Electrochemotherapy is now in routine clinical use to treat cutaneous metastases of any histology, and is listed in national and international guidelines for cutaneous metastases and primary skin cancer. Electrochemotherapy is used by dermatologists, surgeons, and oncologists, and for different degrees and manifestations of metastases to skin and primary skin tumours not amenable to surgery. This treatment utilises electric pulses to permeabilize cell membranes in tumours, thus allowing a dramatic increase of the cytotoxicity of anti-cancer agents. Response rates, often after only one treatment, are very high across all tumour types. The most frequent indications are cutaneous metastases from malignant melanoma and breast cancer. In 2006, standard operating procedures (SOPs) were written for this novel technology, greatly facilitating introduction and dissemination of the therapy. Since then considerable experience has been obtained treating a wider range of tumour histologies and increasing size of tumours which was not originally thought possible. A pan-European expert panel drawn from a range of disciplines from dermatology, general surgery, head and neck surgery, plastic surgery, and oncology met to form a consensus opinion to update the SOPs based on the experience obtained. This paper contains these updated recommendations for indications for electrochemotherapy, pretreatment information and evaluation, treatment choices, as well as follow-up. [ABSTRACT FROM AUTHOR]

Following neoadjuvant chemotherapy (NAC) for resectable gastric cancer, the prognostic adequacy of the UICC staging system needs to be investigated. In particular to explore whether the ypTNM curves for radically resected gastric cancer patients receiving NAC follow the stage-matched survival curves of radically resected chemo-naïve patients (pTNM). Further, to disclose any interaction between the TNM-response mode to NAC and stage-specific survival rates, i.e., whether survival for a particular pathological disease stage was dependent on whether this was reached through a downstaging or as stable disease following NAC. Retrospective study on radically resected patients ≤ 75 years of age with gastric adenocarcinoma stages I-III diagnosed during 2001–2016. The patients constitute two population-based cohorts; the SURG-group with n = 121 patients treated before 2007 when NAC was introduced, and the NAC-group with n = 126 patients diagnosed since early 2007, receiving NAC and subsequent radical resection. Long-term survival rates were similar when specific ypTNM-stages were compared to their corresponding pTNM chemo-naïve counterparts. The dichotomised N0 vs. N + had a substantial impact on the long-term survival rates in both groups, however, no discrepancy in long-term survival rates between pN0 vs. ypN0, and pN + vs. ypN + was found. The pathological stage determined long-term survival rates irrespective of the baseline disease stage, as no interaction between the response mode and stage-specific survival rates was found. Survival curves for specific ypTNM-stages following NAC did not differ from the corresponding survival curves of their chemo-naïve pTNM counterparts. The interpretation is that NAC affected the gastric cancer, lymph nodes, and micrometastases, in such a way that the final ypTNM-stage provided similar prognostic information as the chemo-naïve pTNM-stages. Survival rates were contingent on the final ypTNM-stages alone, and not influenced by the response mode to reach that particular disease stage, or predetermined by the original clinical TNM-stage.

Using real-world (RW) data from registries to mimic or substitute a comparator arm of clinical trials is increasingly investigated. The feasibility of using data sources for this purpose depends on the source's completeness of the wide spectrum of a disease characteristics and relevant endpoints, which could allow for proper matching of important variables. This is a Norwegian study using data from three population-based registries, the Cancer Registry (CRN), the National Patient Registry (NPR), and the Norwegian Prescribed Drug Registry (LMR). We assessed if the registries contained the information necessary for selecting a RW cohort of patients with characteristics that mimicked the inclusion and exclusion criteria from the control arm of the phase 3 trial (KeyNote-407) on patients with stage IV, squamous NSCLC. We did this both on an aggregated - and individual data level. We also described the survival in the RW-cohorts and compared it with the survival in the control arm of the KN-407 trial. Using aggregated data from the CRN allowed us to find the patients based on some clinically relevant inclusion criteria, but only to a limited extent could we apply the exclusion criteria of KN-407. When we used individual data from the CRN, NPR and the LMR we could create a patient cohort that shared more criteria corresponding to the eligibility criteria from KN-407, including exclusion criteria. Compared to the 11.3 months (CI 95% 9.5, 14.8) median survival in the control arm of KN-407, both RW-cohorts had a shorter median survival, 7.07 months (CI 95% 6.7, 9.5) (individual) and 8.0 months (CI 95% 5.8, 10.5) (aggregated). Even if we demonstrated that the registries contain clinically relevant information necessary to mimic the eligibility criteria of a selected RCT, the survival is shorter for RW patients compared to their control arm counterpart in the RCT.

BackgroundTreatment of cancer with chemotherapy decreases endurance capacity and muscle strength. Training during chemotherapy might prevent this. There are no clear guidelines concerning which type of training and which training dose are effective. This review aims to gain insight into the different training modalities during chemotherapy and the effects of such training to improve endurance capacity and muscle strength in order to obtain the knowledge to compose a future training program which trains cancer patients in the most effective way.Material and methodsA systematic search of PubMed was carried out. In total, 809 studies of randomized controlled trials studying the effects of training during chemotherapy on endurance capacity and muscle strength were considered. Only 14 studies met all the inclusion criteria. The studies were assessed on methodological quality by using Cochrane criteria for randomized controlled trials.ResultsThe quality of the studies was generally poor and the study populations varied considerably as the training programs were very heterogeneous. Variables of endurance capacity reported beneficial effects in 10 groups (59%). Increases due to training ranged from 8% to 31%. Endurance capacity decreased in nine of 13 control groups (69%), which ranged from 1% to 32%. Muscle strength improved significantly in 17 of 18 intervention groups (94%), ranging from 2% to 38%. Muscle strength also improved in 11 of 14 control groups (79%), but this increase was only minimal, ranging from 1.3% to 6.5%.ConclusionsThis review indicates that training during chemotherapy may help in preventing the decrease in muscle strength and endurance capacity. It is important to know which training intensity and duration is the most effective in training cancer patients, to provide a training program suitable for every cancer patient. Training should be based on good research and should be implemented into international guidelines and daily practice. More research is needed. [ABSTRACT FROM PUBLISHER]

With the advent of multimodality therapy, the overall five-year survival rate from childhood cancer has improved considerably now exceeding 80% in developed European countries. This growing cohort of survivors, with many years of life ahead of them, has raised the necessity for knowledge concerning the risks of adverse long-term sequelae of the life-saving treatments in order to provide optimal screening and care and to identify and provide adequate interventions. Childhood cancer survivor cohorts in Europe. Considerable advantages exist to study late effects in individuals treated for childhood cancer in a European context, including the complementary advantages of large population-based cancer registries and the unrivalled opportunities to study lifetime risks, together with rich and detailed hospital-based cohorts which fill many of the gaps left by the large-scale population-based studies, such as sparse treatment information. Several large national cohorts have been established within Europe to study late effects in individuals treated for childhood cancer including the Nordic Adult Life after Childhood Cancer in Scandinavia study (ALiCCS), the British Childhood Cancer Survivor Study (BCCSS), the Dutch Childhood Oncology Group (DCOG) LATER study, and the Swiss Childhood Cancer Survivor Study (SCCSS). Furthermore, there are other large cohorts, which may eventually become national in scope including the French Childhood Cancer Survivor Study (FCCSS), the French Childhood Cancer Survivor Study for Leukaemia (LEA), and the Italian Study on off-therapy Childhood Cancer Survivors (OTR). In recent years significant steps have been taken to extend these national studies into a larger pan-European context through the establishment of two large consortia - PanCareSurFup and PanCareLIFE. The purpose of this paper is to present an overview of the current large, national and pan-European studies of late effects after childhood cancer. This overview will highlight the strong cooperation across Europe, in particular the EU-funded collaborative research projects PanCareSurFup and PanCareLIFE. Overall goal. The overall goal of these large cohort studies is to provide every European childhood cancer survivor with better care and better long-term health so that they reach their full potential, and to the degree possible, enjoy the same quality of life and opportunities as their peers.

Cancer treatment frequently results in chemotherapy-induced peripheral neuropathy (CIPN), which is a side effect that is now neither properly preventable nor treatable. Physical therapy has been studied in this patient population and is frequently utilised for neurological rehabilitation after damage. This study set out to thoroughly review randomised controlled trials (RCTs) examining the efficacy of physical therapy for patients with chemotherapy-induced peripheral neuropathy. From their beginning in January 2017 to January 2023, EMBASE, PubMed, Medline, PEDro, and the Cochrane Library were searched for pertinent RCTs. Additionally, manual search techniques were applied. On the basis of the inclusion criteria, two reviewers independently determined the study's eligibility. Reviewers evaluated the quality of the studies and took note of their methodologies, designs, interventions, outcomes, and conclusions. Ten RCTs met all inclusion criteria. Overall results are constrained by the variety of interventions and the small sample sizes of the included studies, which also indicate the need for more studies. Physical therapy has additional benefits for enhancing the quality of life of patients with peripheral neuropathy brought on by chemotherapy. [ABSTRACT FROM AUTHOR]

Convincing results from randomized controlled trials (RCTs) have led to increasing use of immune checkpoint inhibitors (ICI) as part of standard therapies in real-world (RW) scenarios. However, RW patients differ clinically from RCT populations and might have reduced long-term survival. Currently, only sparse data on 3-5-year survival rate for RW patients with advanced non-small cell lung cancer (NSCLC) treated with ICI exist. A multicenter study was performed including 729 patients with advanced NSCLC receiving monotherapy with ICI (retrospective data (n = 566) and prospective data (n = 163)). Detailed baseline clinical characteristics, programmed death-ligand 1 (PD-L1) tumor proportion score (TPS), and baseline haematological count were registered. Kaplan–Meier estimates and log-rank test were used for survival analyses, Cox regression for determination of prognostic factors. Median time of follow-up (FU) was 48.7 months (IQR 37.2–54.3). Median overall survival (OS) in first line treatment was 20.4 months (IQR 8.5–45.0) compared to 11.4 months (IQR 4.6–27.1) in ≥2nd line (HR 1.48, 95% CI 1.25–1.75). Estimated probability of OS was 30% at 3 years, 23% at 4 years, and 13% at 5 years in first line compared to 17, 13, and 11% in ≥2nd line, respectively. For those with performance status (PS) 2, the 2-year OS rate was 32% (95% CI 0.22–0.43) compared to 5% (95% CI 0.01–0.15) in patients with PD-L1 ≥ 50% versus <50%, respectively. Compared to RCTs, long-term OS and PFS rates are lower in real-world patients treated with ICI in first line but much improved compared to historic rates on chemotherapy. A promising flattening of both the OS and progression free survival curves illustrates that also a subset of real-world patients obtain long-term remission. Patients with PS 2 and PD-L1 ≥ 50% may obtain clinically meaningful 2-year PFS and OS rates. [ABSTRACT FROM AUTHOR]

Background: Men with testicular cancer receiving platinum-based chemotherapy have an increased risk of thromboembolic events, with incidence rates between 8–24%. A recent trial evaluating the effect of high-intensity interval training (HIIT) prematurely closed as three out of nine participants (33%) in the intervention group developed a thromboembolic event. The purpose of this retrospective cohort study was: 1) (primary) to evaluate the incidence of thromboembolic events in men receiving chemotherapy for testicular cancer who had participated in HIIT during a 6-week exercise program (Body & Cancer) 2) to describe the feasibility of this program. Material and methods: Forty men who had participated in at least one HIIT session from February 2007 to February 2020 were included. Electronic medical records were searched for incident thromboembolic events (arterial and venous) during Body & Cancer and up to one-year post-chemotherapy. Attendance, cardiorespiratory fitness (VO2-peak), and upper and lower extremity muscular strength (1 repetition maximum (RM)) were obtained from the Body & Cancer database. Results: One participant developed a thromboembolic event during Body & Cancer. No participants developed a thromboembolic event in the follow-up period. In all, data represent 160 HIIT sessions with a median attendance of eight sessions [range 1–19]. Statistically significant increases in upper and lower extremity strength were observed (8.6 (4.2 to 13.0) and 26.0 (14.9 to 37.0) kg, respectively). No significant increase in cardiorespiratory fitness was found (0.14 (−0.03 to 0.31) l/min). Conclusion: While conclusions on the safety of HIIT cannot be drawn, data from the present study do not support previous findings cautioning avoidance of HIIT due to a possible added risk of thromboembolic events in men receiving platinum-based chemotherapy for testicular cancer. Considering the potential for positive effects on cardiovascular outcomes associated with HIIT, future studies with robust design should be performed in this population to confirm these observations.

Fear of cancer recurrence (FCR) in breast cancer survivors (BCSs) is common, associated with reduced quality of life and effective interventions exist. There are knowledge gaps concerning FCR among long-term, early-stage BCSs and its associations with other late effects. Within a national cohort, we explored these knowledge gaps, with the ultimate aim of improved care for BCSs experiencing long-term FCR. In this cross-sectional study, all BCSs aged 20–65 years with early-stage breast cancer in 2011–2012 (n = 2803), were identified by the Cancer Registry of Norway in 2019 and mailed a survey including the Assessment of Survivor Concerns used to measure FCR. Factors associated with moderate/high FCR (defined as a sum score of ≥ 6 of a possible range 3–12, or a single score on one of the items of ≥ 3) were explored using a three-block regression analyses including relevant sociodemographic-, health- and cancer-related variables. In total, 1311 BCSs were included (47%). Median age at survey was 60 years. Fifty-six % reported moderate-to-high FCR, associated with younger age (OR 0.96, 95% CI 0.95–0.97) and receiving chemo- and endocrine therapy (OR 1.59, 95% CI 1.15–2.20). After adding late effects into the model, FCR remained significantly associated with these variables, in addition to sleep disturbances (OR 1.58, 95% CI 1.18–2.10). In the final block, adding mental distress, FCR remained significantly associated with younger age (OR 0.97, 95% CI 0.96–0.99), receiving chemo- and endocrine therapy (OR 1.14, 95% CI 1.00–1.97), sleep disturbances (OR 1.44, 95% CI 1.08–1.94) and anxiety (OR 2.67, 95% CI 1.38–5.19). FCR was prevalent eight years after early-stage breast cancer. Being younger, receiving intensive treatment, experiencing sleep disturbances and/or anxiety were associated with moderate/high FCR. Addressing FCR should be part of standard follow-up care of long-term BCSs. [ABSTRACT FROM AUTHOR]

Hippocampus is a central component for neurocognitive function and memory. We investigated the predicted risk of neurocognitive impairment of craniospinal irradiation (CSI) and the deliverability and effects of hippocampal sparing. The risk estimates were derived from published NTCP models. Specifically, we leveraged the estimated benefit of reduced neurocognitive impairment with the risk of reduced tumor control. For this dose planning study, a total of 504 hippocampal sparing intensity modulated proton therapy (HS-IMPT) plans were generated for 24 pediatric patients whom had previously received CSI. Plans were evaluated with respect to target coverage and homogeneity index to target volumes, maximum and mean dose to OARs. Paired t-tests were used to compare hippocampal mean doses and normal tissue complication probability estimates. The median mean dose to the hippocampus could be reduced from 31.3 GyRBE to 7.3 GyRBE (p <.001), though 20% of these plans were not considered clinically acceptable as they failed one or more acceptance criterion. Reducing the median mean hippocampus dose to 10.6 GyRBE was possible with all plans considered as clinically acceptable treatment plans. By sparing the hippocampus to the lowest dose level, the risk estimation of neurocognitive impairment could be reduced from 89.6%, 62.1% and 51.1% to 41.0% (p <.001), 20.1% (p <.001) and 29.9% (p <.001) for task efficiency, organization and memory, respectively. Estimated tumor control probability was not adversely affected by HS-IMPT, ranging from 78.5 to 80.5% for all plans. We present estimates of potential clinical benefit in terms of neurocognitive impairment and demonstrate the possibility of considerably reducing neurocognitive adverse effects, minimally compromising target coverage locally using HS-IMPT.

Osimertinib is a recently approved third-generation epidermal growth factor receptor tyrosine kinase inhibitor (EGFR-TKI) that selectively inhibits both EGFR-TKI-sensitizing and EGFR-T790M resistance mutations. The aim of the present meta-analysis was to investigate the efficacy and safety of osimertinib for patients with EGFR-mutated non-small-cell lung cancer (NSCLC). Databases were searched for randomized controlled studies that reported the efficacy and safety of osimertinib versus other treatments (chemotherapy, other EGFR-TKIs, etc.) in treating EGFR-mutated NSCLC. The measured effects included objective response rate (ORR), disease control rate (DCR), progression-free survival (PFS), central nervous system progression-free survival (CNS-PFS), and overall survival (OS). Additional outcome was the incidence of adverse event. Relative risk (RR) for incidence and hazard ratio (HR) for survival outcomes were pooled. Seven studies containing 3335 participants were finally included. Osimertinib tended to improve ORR and DCR (RRs >1) as compared with other treatments. Osimertinib was also a significant protective factor for PFS, CNS-PFS, and OS (HRs <1 and p <.05). Osimertinib showed similar advantages in improving tumor response and patient survival when used as first-line, second-line, and third-line/adjuvant therapy, respectively, as compared with other treatments (RRs >1 for ORR and DCR; HRs <1 for PFS, CNS-PFS, and OS). Osimertinib also had better therapeutic effects as compared with chemotherapy, other EGFR TKIs, docetaxel + bevacizumab, and placebo, respectively. The five most common adverse events with pooled incidence > 20% were diarrhea, rash, nail effects, dry skin, and stomatitis, yet the pooled incidence of serious adverse events was less than 2%. This meta-analysis suggests that osimertinib has a positive effect in disease control and survival for patients with EGFR-mutated NSCLC with acceptable toxicities. [ABSTRACT FROM AUTHOR]

Electrochemotherapy (ECT) is an established treatment for primary and secondary cutaneous tumours. The method combines chemotherapy with electroporation, thus increasing the cytotoxic effect of the chemotherapeutic drug. Bleomycin is the drug of choice for ECT, as it is already well established as a treatment for several cancer types and has the largest increase in efficacy after electroporation, enhancing the cytotoxic effect several hundred fold. The response rates of ECT have over the past 30 years been high and consistent. Case based reports point out that the efficacy possibly can be maintained even when the dose of bleomycin is reduced. Consequently in 2018, studies began investigating reducing the bleomycin dose. The purpose of this review is to summarise all data published using intravenous bleomycin for cutaneous malignancies and is to our knowledge the first review to examine the use of a reduced bleomycin dose in ECT. This study is a systematic review. Fifty-five clinical studies investigating ECT with intravenous bleomycin for patients with cutaneous malignancies were included. Studies published from 1993 to 2021 investigating the effect of ECT include 3729 patients and indicate a consistent and high response with a mean objective response rate (ORR) of 81.5%. Interestingly, studies using lower doses of bleomycin observe a similar ORR (85.5%), opening the possibility that a lower dose may not be inferior. This study gives an overview of published studies on ECT with intravenous bleomycin for patients with cutaneous malignancies, including the use of a reduced bleomycin dose, as preparation for a randomised study.

Anthracycline induced cardiotoxicity is well recognized but only few data exist in sarcoma patients. This study retrospectively aimed to analyze sequential Cadmium Zinc Telluride (CZT)-multigated equilibrium radionuclide angiography (ERNA) for monitoring left ventricular ejection fraction (LVEF) and to assess the real-life incidence of cardiotoxicity in sarcoma patients receiving doxorubicin based chemotherapy. A retrospective analysis was performed on all sarcoma patients referred to Herlev University Hospital between 2012 and 2015. Cardiotoxicity was defined as a decline in LVEF of > 10% percentage point to a LVEF < 50% as compared to baseline. Early cardiotoxicity was defined as < 1 year and late cardiotoxicity as ≥ 1 year. Recovery of cardiotoxicity was defined as a LVEF ≥ 50%. A total of 149 patients were referred, 75 (50%) sarcoma patients were included. The main reason for exclusion was that only one CZT-ERNA had been performed in 50 (68%) of the patients. Twenty-three (31%) of the patients experienced cardiotoxicity, 11 (48%) were female, mean age was 56.9 years. Early cardiotoxicity was observed in 16 (70%) of the patients and 11 (48%) experienced clinical symptoms of cardiotoxicity at diagnosis. Recovery of LVEF was seen in 12 (55%) of the patients and persistent recovery in 10 (45%). The diastolic blood pressure at baseline was positively and significantly associated with a higher risk of developing cardiotoxicity (Relative Risk (RR): 1.039 (95% CI= 1.001 − 1.079; p = 0.042)). The median survival was 1.4 years (range 0.5 − 2.2 years) for patients with metastatic disease versus 3.9 years (range 1.5 − 6.4 years) (p = 0.009) for localized disease at baseline. Cardiotoxicity is a relative frequent complication in sarcoma patients treated with doxorubicin based chemotherapy and the diastolic blood pressure at baseline was significantly associated with a higher risk of developing cardiotoxicity.

Prevalence of peripheral neuropathy (PN) has been studied in patients undergoing treatment with taxanes, platinums and vinca alkaloids. The prevalence is unknown in the general oncological cancer population, characterized by advanced age, comorbidities and heterogeneous treatments. A cross-sectional survey was administered to all adult patients, attending outpatient services at three Danish departments of oncology. The survey contained the EORTC-CIPN20, the EORTC-QLQ-C30, the GAD7 and PHQ9 questionnaires. A high PN symptom score was defined as a summary score ≥30 points on the CIPN20. P-values were adjusted for multiple testing. With an overall response rate of 83% (2839 patients), prevalence of PN was 17% overall, varying from 6 to 33% between diagnosis groups. A high score was more common among females (19 vs. 14%, p =.008), smokers (21 vs. 15%, p =.04), patients living alone (21 vs. 15%, p =.002) and patients using cannabis (29 vs. 15%, p <.001), as well as patients suffering from diabetes (26 vs. 16%, p <.001), cardiac heart disease (27 vs. 16%, p <.001), arthritis (32 vs. 15%, p <.001) or chronic obstructive pulmonary disease (25 vs. 16%, p =.01). High score patients were also older (69ys vs 67ys, p =.048) and more likely experiencing polypharmacy (OR = 3.38 [95% CI, 2.64;4.35]). Patients with a high CIPN20 symptom score scored worse on all EORTC QLQ-C30 function and symptom scales. The mean adjusted C30 SumScore difference was −18.66 ([95% CI, −20.31; −17.02], p <.001). Symptoms of PN are experienced widely across cancer groups in the oncology setting. PN symptoms were associated with clinically relevant worse health-related quality of life and with patient-related factors as living alone, various comorbidities, polypharmacy, and cannabis use.

Short-course radiotherapy with consolidation chemotherapy (SCRT-CCT) has emerged as a promising alternative to the long course chemoradiotherapy (LCRT) regimen in locally advanced rectal cancer management. The systematic review and meta-analysis is aimed at summarizing current evidence on SCRT-CCT and comparing it to LCRT. Electronic databases of MEDLINE, Web of Science, and Cochrane library were searched using a predefined search strategy returning 3314 articles. This review included 11 studies (6 randomized trials and 5 non-randomized studies) on SCRT-CCT regimen based on seven different cohorts. Weighted arithmetic means and forest plots were generated to determine summary estimates. The probability of achieving pathological complete response (pCR) was higher with SCRT-CCT compared to LCRT (risk ratio [RR] = 1.75, 95% confidence interval [CI]: 1.41–2.19). No statistically significant difference in 3-year overall survival (OS) was observed between the two groups (RR= 1.06, 95% CI: 0.98–1.14). The weighted arithmetic mean of 3-year OS and pCR was 83.6% versus 80.9%, and 24.5% versus 13.6% for SCRT-CCT and LCRT, respectively. R0 resection and T-downstaging rates ranged from 69.2–100% to 47–75% for SCRT-CCT, and 71–92.3% and 41–75% for LCRT, respectively. The regimens had similar compliance, postoperative, and late toxicity, however, acute toxicity rates varied primarily due to differences in treatment protocols. This review highlights the ability of SCRT-CCT to produce improved tumor response with comparable OS, R0 resection, and T-downstaging at the cost of increased acute toxicity. However, heterogeneity in treatment protocols across studies makes it difficult to provide definitive conclusions regarding the regimen. Several ongoing trials are expected to provide further evidence confirming the findings of RAPIDO trial and detail appropriate SCRT-CCT protocols to improve oncological outcomes, minimize toxicity, and determine its effectiveness as the standard-of-care for locally advanced rectal cancer patients.

The incidence of primary cardiac lymphoma (PCL) is increasing, but the optimal management approach remains unclear. We assessed the clinical characteristics of a single-centre cohort with the goal of determining the optimal management approach. The treatment outcomes and prognostic factors are reported. All PCL patients were diagnosed via biopsy guided by whole-body imaging (positron emission tomography/computed tomography [PET/CT] and/or contrast-enhanced CT]. Curative therapy involved either surgery or prephase steroids followed by definitive immunochemotherapy, depending on the histological type. The primary outcomes were overall survival (OS) and progression-free survival (PFS); the secondary outcome was the treatment response. Twenty-two PCL patients (14 males, 8 females; age: 59.5 ± 14.7 years [mean ± S.D.]) were histologically confirmed to have diffuse large B-cell lymphoma (DLBCL; n = 17 [77.3%]), fibrin-associated DLBCL (FA-DLBCL) (n = 4 [18.2%]) and Burkitt lymphoma (n = 1 [4.5%]). Seven patients underwent cardiotomy (three for biopsy, four with curative intent). The median and longest follow-up periods were 16.3 and 180.0 months, respectively. The 16 patients who received curative therapy (complete response [CR], n = 15 [93.8%]; partial response [PR], n = 1 [6.2%]) showed better survival than those who did not (5-year OS: 83.0 ± 11.3% vs. 0%; hazard ratio [HR]: 0.025[95% confidence interval, CI: 0.003–0.187], p < 0.001); 5-year PFS: 78.7 ± 11.0% vs. 0%, HR= 0.010[0.001–0.093], p < 0.001). The left ventricular ejection fractions (LVEF) before and after definitive treatment was 63.6 ± 2.4% and 64.6 ± 4.5%, respectively (p = 0.275, power = 0.318). Extrapericardial lesions were associated with poorer survival (5-year OS: 40.0 ± 29.7% vs. 100%, p = 0.027; 5-year PFS:40.0 ± 21.9% vs. 100%, p = 0.010). Whole-body imaging is essential for diagnosis and prognosis. Curative therapy provided reasonable outcomes and survival; extrapericardial lesions were associated with a poorer treatment response.

Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting side effect of Hodgkin's lymphoma (HL) treatment. We aimed to describe the prevalence of CIPN associated symptoms in long-term HL survivors compared to controls, and determine associated factors, including impact on health-related quality of life (HRQoL). A questionnaire, including EORTC QLQ-CIPN-20 for CIPN related symptoms and SF-36 for HRQoL, was completed by 303 HL survivors at a median of 16 years after diagnosis. CIPN results were compared to a normative population (n = 606). CIPN associated factors were identified by linear regression analysis. Total CIPN score and subscores were significantly higher in HL survivors compared to controls. In multivariate analysis of HL survivors, a number of comorbidities (p < 0.001) and female gender (p = 0.05) were significantly associated with more CIPN. No association with disease or treatment factors was found. In a multivariate analysis including survivors and controls, the number of comorbidities (p < 0.001) and caseness (p < 0.001) were significantly associated with more CIPN. In HL survivors higher CIPN score was associated with reduced HRQoL (p < 0.001). HL survivors more than a decade after treatment report higher neuropathy-related symptom burden than controls, with a negative impact on HRQoL. Symptoms may be related to factors other than neurotoxic chemotherapy. [ABSTRACT FROM AUTHOR]

In the article, the authors discuss their retrospective analysis of the effects of centralised care of younger patients with acute myeloid leukaemia (AML) in the U.S. and Czech Republic. Other topics include the data on early mortality following allogeneic transplantation of haematopoietic stem cells (HSCT), and the complete remission (CR) rate following induction chemotherapy.

This study aims to investigate patient- and disease characteristics associated with survival in malignant pleural mesothelioma (MPM) patients with anti-tumor treatment or with best supportive care (BSC). Consecutive MPM cases diagnosed in North Denmark Region from 1972 to 2015 were reevaluated and verified by two pathologists using modern immunohistochemical techniques. Danish registries and hospital records were used to gather patient-, asbestos exposure-, and disease information. Of the 279 patients, anti-tumor treatment was administered to 184 patients (66.0%). All of those received chemotherapy alone or as part of a multimodal treatment, where pemetrexed was given to 126 (68.5%) patients. Asbestos exposure was documented in 92.5% of all patients. In the treated group, mean age was lower (66 years versus 74 years, p < 0.01), rate of occupational asbestos exposure was higher (74.5 versus 54.7%, p < 0.01), more patients had better performance score (98.4 versus 60%, p < 0.01) and stage was lower (81 versus 63.2%, p < 0.01) compared to the BSC group. Multivariate analysis showed that epithelioid subtype was the only common prognostic factor for OS in both groups. In BSC patients, good PS and female gender was associated with improved OS. Median overall survival (OS) was 17 versus 4 months (p < 0.01), and independently of the histopathological subtype, the median and 2-year survival was higher in the treated versus the BSC group (p < 0.02). This retrospective study showed that epithelioid subtype is the only independent positive prognostic factor of survival in treated patients with MPM. For BSC patients, the epithelioid subtype, good PS, and female gender were positive prognostic factors, while age and comorbidities were not significant. This study with long-term follow-up of treated and BSC MPM patients can contribute to the clinical stratification of patients. Further validation is appropriate to verify these findings.

Objectives: Two phase III trials show that maintenance pemetrexed therapy after platinum-doublet chemotherapy prolongs overall survival (OS) and progression free survival (PFS) in advanced non-squamous non-small-cell lung cancer (NSCLC). However, few patients in the control arms received pemetrexed at progression in these trials, performance status (PS) two patients were ineligible and few of the participants were elderly. Thus, we designed this study comparing immediate switch-maintenance pemetrexed therapy with pemetrexed at progression after platinum-doublet chemotherapy. Methods: Patients with stage IIIB/IV non-squamous NSCLC, ≥18 years, PS 0–2, and non-progression after four courses of carboplatin/vinorelbine were randomized to receive immediate maintenance pemetrexed therapy or observation followed by pemetrexed at progression. The primary endpoint was OS, secondary endpoints were PFS, toxicity and health related quality of life (HRQoL). Results: 105 patients were randomized between May 2014 and September 2017. Median age was 67 years, 36% were >70 years, 9% had PS 2, 91% stage IV and 47% were women. In the observation arm, 73% received pemetrexed at progression. Patients in the maintenance arm had a numerically longer OS (median 12.0 vs. 10.0 months; p =.10) and a statistically significant longer PFS (median 3.1 vs. 1.9 months; p <.01). In multivariable analyses adjusting for baseline characteristics, there was a trend toward improved OS (HR 0.65, 95% CI 0.42–1.01); p =.05), and a significantly improved PFS (HR 0.53, 95% CI 0.35–0.80; p <.01). There were no significant differences in toxicity or HRQoL between the treatment arms. Conclusion: There was a trend toward prolonged OS and significantly longer PFS from switch- maintenance pemetrexed therapy when 73% of patients in the control arm received pemetrexed at progression.

Background: In 2013, eribulin was reimbursed under a coverage with evidence development (CED) as third or later chemotherapy line for advanced breast cancer (ABC) patients in the Netherlands because of uncertain cost effectiveness. In 2016, the final decision of reimbursing eribulin was taken without considering the evidence collected during CED research. We analysed the cost effectiveness of eribulin versus non-eribulin chemotherapy, using real-world data. Methods: A three health states (progression-free, progressed disease, dead) partitioned survival model was developed. The SOuth East Netherlands Advanced BREast Cancer (SONABRE) registry informed the effectiveness and costs inputs. Health state utility values were obtained from the literature. Incremental cost-effectiveness ratio (ICER) between the eribulin and matched non-eribulin chemotherapy was estimated. Deterministic and probabilistic sensitivity analyses and scenario analyses were performed. The financial risk (i.e., the expected value of perfect information (EVPI) plus the expected monetary loss (eML) associated with reimbursing eribulin) and budget impact associated with reimbursing eribulin were calculated. Results: Eribulin led to higher health benefits (0.07 quality-adjusted life year (QALY)) and costs (€15,321) compared with non-eribulin chemotherapy. This resulted in an ICER of €220,608. At a €80,000 per QALY threshold, the risk of reimbursing eribulin was €9,791 per patient (EVPI €13, eML €9,778). Scaled up to the Dutch population, the estimated annual budget impact was €1.9 million and the annual risk of reimbursing eribulin was €2.7 million. Conclusion: From a Dutch societal perspective, eribulin is not cost effective when considering its list price as third and later chemotherapy line for ABC patients. [ABSTRACT FROM AUTHOR]

Background: Previously, we showed that reintroduction of the same (first-line) chemotherapy at progression could only partially make up for the loss in efficacy as compared to continuously delivered first-line chemotherapy. Here, we report the probability of starting second-line study chemotherapy in the Stop&Go trial, and the progression-free survival (PFS) and overall survival (OS) of patients who received both the first- and second-line treatment in an intermittent versus continuous schedule. Methods: First-line chemotherapy comprised paclitaxel plus bevacizumab, second-line capecitabine or non-pegylated liposomal doxorubicin, given per treatment line as two times four cycles (intermittent) or as eight consecutive cycles (continuous). Results: Of the 420 patients who started first-line treatment within the Stop&Go trial (210:210), a total of 270 patients continued on second-line study treatment (64% of all), which consisted of capecitabine in 201 patients and of non-pegylated liposomal doxorubicin in 69 patients, evenly distributed between the treatment arms. Median PFS was 3.7 versus 5.0 months (HR 1.07; 95% CI: 0.82–1.38) and median OS 10.9 versus 12.4 months (HR 1.27; 95% CI: 0.98–1.66) for intermittent versus continuous second-line chemotherapy. Second-line PFS was positively influenced by prior hormonal therapy for metastatic disease and longer first-line PFS duration, while triple-negative tumor status had a negative influence. Patients with a shorter time to progression (TTP) in first-line (≤10 months) had a higher probability of starting second-line treatment if they received intermittent compared to continuous chemotherapy (OR 1.97; 95% CI: 1.02–3.80). Conclusion: We recommend continuous scheduling of both the first- and second-line chemotherapy for advanced breast cancer. [ABSTRACT FROM AUTHOR]

Background: Glioblastoma (GBM) is an aggressive brain tumor with a short overall survival (OS) in general. The treatment of GBM has evolved over the last decades and is today multimodal including surgical resection followed by radiochemotherapy and adjuvant chemotherapy for patients in good performance status. The aim of this study was to evaluate the development of treatment and the outcome for GBM patients at a single regional center. Patients and methods: Survival was studied for 571 patients in our region diagnosed with GBM between 1995 and 2015. Samples from 244 patients out of those treated 2005-2015 have been included in a tissue/blood bank and a clinical database has been set up with basic patient characteristics and details on surgery and non-surgical treatment. Results: The median OS for all patients from 1995 to 2015 was 9.3 months. There was a stepwise improvement from 6.9 to 10.3 months for patients diagnosed 1995-1996 and 2010-2015, respectively (p < .05). The 2-year survival for the same time periods improved from 7% to 18% (p < .01). After introduction of postoperative radiochemotherapy for patients in good performance status in 2005 an increased OS was noted and following implementation of intraoperative 5-aminolevulinic acid the number of tumor resection ≥95% did increase from 33% to 54% (p < .001). Positive prognostic factors for survival were young age, good performance status, absence of inflammatory disease, absence of diabetes or metabolic disease, tumor resection ≥95%, and completion of postoperative radiochemotherapy. Discussion: The results of this study are consistent with earlier results regarding survival and prognostic factors and confirm results from randomized controlled trials in a clinical setting. Despite the improvements made, the prognosis is still dismal and the need for further research on GBM treatment is great. [ABSTRACT FROM AUTHOR]

Background: The long-term toxicities after cisplatin-based chemotherapy (CBCT) reveal a remarkable inter-individual variation among testicular cancer survivors (TCSs). Therefore, we assessed long-term platinum (Pt) changes and their associations with CBCT-related late effects in TCSs. Material and methods: In 77 TCSs treated with CBCT from 1984 to 1990, blood samples for analyses of Pt and a questionnaire including self-reported neuro- and ototoxicity (NTX) symptoms were collected during two follow-up surveys at median 12 (Survey I; SI) and 20 (Survey II; SII) years after treatment. Information about second cancers after SII was retrieved from the Norwegian Cancer Registry. Results: A larger Pt decline from SI to SII was associated with a decreased risk of a second cancer diagnosis (HR 0.78, 95% CI 0.62-0.99 per 10 ng/L/year), and worsening of paresthesias in hands (OR 1.98, 95% CI 1.09-3.59 per 10 ng/L/year) and tinnitus (OR 1.51, 95% CI 1.01-2.27 per 10 ng/L/year). Conclusion: In summary, we found a significant association between a larger Pt decline and a reduced risk of second cancers and deterioration of paresthesias in hands and tinnitus.

Background: Hearing loss is a well-known long-term effect after cisplatin-based chemotherapy (CBCT) in testicular cancer survivors (TCS), but longitudinal data are sparse. We evaluate hearing loss and the impact of age in TCS treated with CBCT in this longitudinal study. Material and methods: Forty-six TCS treated with CBCT 1980-1994 with audiograms (0.25-8 kHz) prechemotherapy (PRE) and at a follow-up survey (SURV) after median 10 years were included (cases). Audiograms at SURV from 46 age-matched TCS without CBCT were included as controls. Linear regression was performed to evaluate predictors for change in the hearing threshold level (HTL) from PRE to SURV. Two definitions of a audiogram-defined hearing loss was applied if: (1) mean HTL for both ears exceeded 20 dB at any frequency 0.25-8 kHz (American Speech-Language-Hearing Association (ASHA) definition) and (2) average HTL for the frequencies 0.5, 1, 2 and 4 kHz exceeded 20 dB (WHO-M4 definition). Self-reported hearing impairment (SURV) was assessed by a questionnaire. Results: Age and cisplatin dose was significantly associated with a greater change in HTL for the frequencies 2-8 kHz. For the 8 kHz frequency, each 100mg increase in cumulative cisplatin dose was associated with a deterioration of 3.6 dB (95% CI 1.8-5.3, p<.001). The prevalence of hearing loss (ASHA) among cases was 33% PRE, 70% at SURV and 65% among controls at SURV (cases vs. controls, p≤.66). According to M4, the prevalence of hearing loss among cases was 6.5% PRE, 13% at SURV and 2.2% among controls at SURV (cases vs. controls, p≤.049). Twenty-nine percent of cases, and 33% of controls (p≤.70) reported hearing impairment at SURV. Conclusion: Cisplatin is associated with a hearing loss particularly at higher frequencies. Age appear to be an important factor for hearing loss regardless of treatment. The ASHA definition overestimates the hearing problem. [ABSTRACT FROM AUTHOR]

Aim: To compare 18F-sodium fluoride positron emission tomography/computed tomography (NaF PET/ CT) and 99mTc-labelled diphosphonate bone scan (BS) for the monitoring of bone metastases in patients with prostate cancer undergoing anti-cancer treatment. Material and methods: Data from 64 patients with prostate cancer were included. The patients received androgen-deprivation therapy (ADT), next-generation hormonal therapy (NGH) or chemotherapy. The patients had a baseline scan and 1-3 subsequent scans during six months of treatment. Images were evaluated by experienced nuclear medicine physicians and classified for progressive disease (PD) or non-PD according to the Prostate Cancer Working Group 2 (PCWG-2) criteria. The patients were also classified as having PD/non-PD according to the clinical and prostate-specific antigen (PSA) responses. Results: There was no difference between NaF PET/CT and BS in the detection of PD and non-PD during treatment (McNemar’s test, p = .18). The agreement between BS and NaF PET/CT for PD/non-PD was moderate (Cohen’s kappa 0.53, 95% confidence interval 0.26-0.79). Crude agreement between BS and NaF PET/CT for the assessment of PD/non-PD was 86% (89% for ADT, n = 28; 88% for NGH, n = 16, and 80% for chemotherapy, n = 20). In most discordant cases, BS found PD when NaF PET/CT did not, or BS detected PD on an earlier scan than NaF PET/CT. Biochemical progression (27%) occurred more frequently than progression on functional imaging (BS, 22% and NaF PET/CT, 14%). Clinical progression was rare (11%), and almost exclusively seen in patients receiving chemotherapy. Conclusion: There was no difference between NaF PET/CT and BS in the detection of PD and non-PD; however, BS seemingly detects PD by the PCWG-2 criteria earlier than NaF-PET, which might be explained by the fact that NaF-PET is more sensitive at the baseline scan.

Introduction: Evaluation of patient characteristics inducing toxicity in breast radiotherapy, using simultaneous modeling of multiple endpoints. Methods and Materials: In 269 early-stage breast cancer patients treated with whole-breast irradiation (WBI) after breast-conserving surgery, toxicity was scored, based on five dichotomized endpoints. Five logistic regression models were fitted, one for each endpoint and the effect sizes of all variables were estimated using maximum likelihood (MLE). The MLEs are improved with James-Stein estimates (JSEs). The method combines all the MLEs, obtained for the same variable but from different endpoints. Misclassification errors were computed using MLE- and JSE-based prediction models. For associations, p-values from the sum of squares of MLEs were compared with p-values from the Standardized Total Average Toxicity (STAT) Score. Results: With JSEs, 19 highest ranked variables were predictive of the five different endpoints. Important variables increasing radiation-induced toxicity were chemotherapy, age, SATB2 rs2881208 SNP and nodal irradiation. Treatment position (prone position) was most protective and ranked eighth. Overall, the misclassification errors were 45% and 34% for the MLE- and JSE-based models, respectively. p-Values from the sum of squares of MLEs and p-values from STAT score led to very similar conclusions, except for the variables nodal irradiation and treatment position, for which STAT p-values suggested an association with radiosensitivity, whereas p-values from the sum of squares indicated no association. Breast volume was ranked as the most significant variable in both strategies. Discussion: The James-Stein estimator was used for selecting variables that are predictive for multiple toxicity endpoints. With this estimator, 19 variables were predictive for all toxicities of which four were significantly associated with overall radiosensitivity. JSEs led to almost 25% reduction in the misclassification error rate compared to conventional MLEs. Finally, patient characteristics that are associated with radiosensitivity were identified without explicitly quantifying radiosensitivity. [ABSTRACT FROM AUTHOR]

Background:Neoadjuvant therapy response correlates with survival in multiple gastrointestinal malignancies. To potentially augment neoadjuvant response for pancreas adenocarcinoma, we intensified treatment with stereotactic body radiotherapy (SBRT) following multi-agent chemotherapy. Using this regimen, we analyzed whether the College of American Pathology (CAP) tumor regression grade (TRG) at pancreatectomy correlated with established response biomarkers and survival. Materials and methods:We identified borderline resectable (BRPC) and locally advanced (LAPC) pancreatic cancer patients treated according to our institutional clinical pathway who underwent surgical resection with reported TRG (n = 81, median follow-up after surgery 24.2 months). Patients had baseline CA19-9, computed tomography (CT), endoscopic ultrasound, and FDG positron emission tomography (PET)/CT then underwent multi-agent chemotherapy (79% with three cycles of gemcitabine, docetaxel and capecitabine) followed by 5-fraction SBRT. They then underwent restaging CT, PET/CT and CA19-9. Overall (OS) and progression-free (PFS) survival were estimated and compared by Kaplan–Meier and log-rank methods. Univariate ordinal logistic regression correlated TRG with baseline, restaging and change in CA19-9 and the PET maximum standardized uptake value (SUVmax). Results:Restaging level and decrease in CA19-9 correlated with improved TRG (p = .02 for both) as did restaging SUVmax (p < .01), yet there was no TRG correlation with decrease in SUVmax (p = .10) or CT response (p = .30). The TRG groups had similar OS and PFS except the TRG 0 (complete response) group. Compared to partial response levels (TRG 1-3, median OS 33.9 months, median PFS 13.0 months), the six (7%) patients with TRG 0 had no deaths (p = .05) and only one progression (p = .03). A group of 10 (12%) TRG 1 patients with only residual isolated tumor cells had similar outcomes to the other TRG 1-3 patients. Conclusion:Pre-operative PET-CT and CA19-9 response correlate with histopathologic tumor regression. Patients with complete pathologic response have superior outcomes, suggesting a rationale for intensification and personalization of neoadjuvant therapy in BRPC and LAPC. [ABSTRACT FROM PUBLISHER]

Background:Electrochemotherapy, the combination of electroporation and chemotherapy, is mainly used in the palliative setting for treatment of cutaneous and subcutaneous metastases; however, new applications are continuously being explored. Patients with head and neck cancer are primarily treated with surgery and/or radio-chemotherapy. In the setting of local recurrence with no further curative treatment options available, electrochemotherapy could be of value. We therefore performed a systematic search of the present literature. Materials and methods:Eligible studies presented data from patients with head and neck cancer treated across the mucosal surface with electrochemotherapy. The search resulted in 11 studies with a total of 72 patients. Results:Overall complete response was reported as good, especially in primary small tumors. Side effects were minor in primary tumors whereas large, recurrent tumors displayed more frequent side effects and some serious adverse events. Design and structure of the studies differed considerably, making general comparisons difficult. Conclusion:Few studies concerning electrochemotherapy on mucosal head and neck tumors are available and they are not easily comparable. Overall response to treatment is good; nonetheless, further systematic studies are warranted. [ABSTRACT FROM PUBLISHER]

BackgroundThis study examined employment patterns and associated factors in lymphoma survivors treated with high-dose chemotherapy with autologous stem cell transplantation (HDT-ASCT) from diagnosis to a follow-up survey at a mean of 10 years after HDT-ASCT. Patients and methodsAll lymphoma survivors aged ≥18 years at HDT-ASCT in Norway from 1987 to 2008, and alive at the end of 2011 were eligible for this cross-sectional study performed in 2012/2013. Participants completed a mailed questionnaire. Job status was dichotomized as either employed (paid work) or not-employed (disability and retirement pension, on economic support, home-makers, or students). ResultsThe response rate was 78%, and the sample (N = 312) contained 60% men. Mean age at HDT-ASCT was 44.3 and at survey 54.0 years. At diagnosis 85% of survivors were employed, 77% before and 77% after HDT-ASCT, and 58% at follow-up. Forty seven percent of the survivors were employed at all time points. The not-employed group at survey was significantly older and included significantly more females than the employed group. No significant between-group differences were observed for lymphoma-related variables. Fatigue, mental distress and type D personality were significantly higher among those not-employed, while quality of life was significantly lower compared to the employed group. Older age at survey, being female, work ability and presence of type D personality remained significantly related to being not-employed at survey in the multivariable analysis. ConclusionsOur findings show that not-employed long-term survivors after HDT-ASCT for lymphoma have more comorbidity, cognitive problems and higher levels of anxiety/depression than employed survivors. These factors should be checked and eventually treated in order to improve work ability. [ABSTRACT FROM PUBLISHER]

ObjectiveTo evaluate the safety, local tumor efficacy and relief of symptoms of electrochemotherapy (ECT) treatment in patients affected by recurrence of vulvar cancer (VC), unsuitable for standard treatments. MethodsTen patients were recruited with histological diagnosis of recurrence of VC. Intravenous bleomycin was injected, after an accurate mapping of all lesions and ECT was performed. Response to therapy was evaluated and quality of life (QoL) was evaluated via questionnaires. ResultsDiagnosis stage of primary tumors, according to the FIGO system, was: four patients respectively at stage IB (40%), and at stage II (40%), one patient at stage IIIA (10%), one patient with Paget cancer (10%). Mean age was 76 years (SD ± 7) at time of enrollment. Eight patients (80%) were previously submitted to surgery and/or radio-chemotherapy. Mean treatment time was 20 (range 10–20) min. After a median follow-up of 12 (3–22) months, six patients (60%) were alive. ConclusionsObjective responses (ORs) with local control of the tumor were obtained in 80%. After a mean follow-up of 12 (3–22) months six patients (60%) were alive. The favorable outcome of this study, indicates that ECT is a reliable treatment option that may improve their functioning, thus enhancing the care provided in the palliative setting.

Background.Comprehensive geriatric assessment (CGA) is a multidimensional method to detect frailty in elderly patients. Time saving could be accomplished by identifying those individual items that classify elderly cancer patients at risk for feasibility of chemotherapy and for mortality. Material and methods.Patients older than 70 years of age were assessed before the first chemotherapy administration. GA consisted of the Mini Nutritional Assessment (MNA), Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE), Groningen Frailty Indicator (GFI) and Mini Mental State Examination (MMSE). Predictive individual items for feasibility of chemotherapy and mortality were entered in the multivariable logistic regression and Cox-regression models, and a three-item sum scale was constructed: the Geriatric Prognostic Index (GPI). Results.The 494 patients had a median age of 75 years (range 70–92 years). The majority of the patients had malignancies of the digestive tract (41.7%) followed by hematological tumors (22.3%). Three items of the MNA (‘psychological distress or acute disease in the past three months’, ‘neuropsychological problems’ and ‘using > 3 prescript drugs’) independently predicted for feasibility of chemotherapy. Two items of the MNA and one of the GFI (‘declining food intake in past 3 months’, ‘using > 3 prescript drugs’, and ‘dependence in shopping’) independently predicted for mortality. In comparison with patients without any positive item on the three-item GPI, patients with one, two or three positive items had hazard ratios (HRs) of 1.58, 2.32, and 5.58, respectively (all p < 0.001). Conclusions.With only three items of the MNA, feasibility of chemotherapy can be predicted. The three-item GPI may help to identify elderly cancer patients at elevated risk for mortality.

Background.R-CHOP-21 has remained the standard chemotherapy for aggressive non-Hodgkin's lymphoma. It was suggested that decreasing the treatment interval from three weeks (CHOP-21) to two weeks (CHOP-14) may improve survival and disease control of patients with aggressive lymphoma. Purpose.To evaluate the effect of CHOP-like-14 (with or without rituximab) compared to standard CHOP-like -21 on overall survival (OS), disease control and toxicity of patients with aggressive non-Hodgkin lymphoma. Methods.Systematic review and meta-analysis of RCTs. In October 2014 we searched The Cochrane Library, MEDLINE, LILACS, conference proceedings, and databases of ongoing trials. Authors were contacted for complementary data. The primary outcome was OS. Results.We identified seven trials (4073 patients), conducted between the years 1999 and 2008. Trials were at low or unclear risk for selection bias, and at low or unclear risk of attrition bias. CHOP-like-14 improved OS of patients with aggressive lymphoma compared to the same regimen given every 21 days (all trials): HR of death 0.86, 95% confidence interval (CI) 0.77–0.97. There was no OS difference between rituximab-CHOP-like 14 to rituximab-CHOP-like-21 (3 trials): HR 0.93 95% CI 0.78–1.10. The rates of progression or death, complete response, treatment-related mortality, grade 3–4 infection, and discontinuation were similar between groups. Conclusion.R-CHOP-21 remains the standard of care for patient with aggressive B-cell lymphoma. CHOP-14 can be considered as in case rituximab is omitted. [ABSTRACT FROM PUBLISHER]

Background and aims. Platelets are believed to promote tumor growth and metastasis but their prognostic role in locally advanced pancreatic cancer (LAPC) remains largely unknown. We assessed whether pretreatment platelet counts independently predict survival outcomes in patients with LAPC treated with chemoradiation (CRT). Methods. We retrospectively reviewed the MD Anderson pancreatic cancer database and identified 199 patients with LAPC treated with CRT between 2006 and 2012. Induction chemotherapy was used prior to consolidative CRT in 177 (89%) patients. Median radiation dose was 50.4 Gy. Concurrent radiosensitizers were gemcitabine-based (13%) or capecitabine-based (84%) regimens. Actuarial univariate and multivariate statistical methods were used to determine significant prognostic factors for overall survival (OS) and progression-free survival (PFS) calculated from the start of treatment. Results. Median follow-up was 9.9 months. Median OS and PFS durations were 17.7 and 10.7 months, respectively. On univariate analysis, platelet count > 300 K/μl, KPS ≤ 80, ≥ 5% weight loss and pretreatment CA19-9 above the median were associated with inferior OS or PFS. Median OS was lower in patients with platelet count > 300 K/μl compared to patients with platelet count ≤ 300 K/μl (10.2 vs. 19 months; p = 0.0002). Corresponding median PFS times were 7.8 months and 11.1 months (p = 0.004), respectively. On multivariate analysis, platelet count > 300 K/μl (p = 0.012), ≥ 5% weight loss (p = 0.002) and elevated pretreatment CA19-9 (p = 0.005) were independent prognostic factors for OS. Platelet count > 300 K/μl (p = 0.03) and KPS ≤ 80 (p = 0.05) independently predicted PFS. Conclusions. Our analysis suggests that pretreatment thrombocytosis independently predicts inferior OS and PFS in LAPC. [ABSTRACT FROM AUTHOR]

A letter to the editor is presented regarding the use of diffusion-weighted magnetic resonance imaging (DW-MRI) to examine chemoradiotherapy (CRT) effect on the salivary glands.

The article discusses the study the treatment of patient with metastatic head and neck squamous cell carcinoma. Topics discussed include method of the study which include analysis of patients with the history of metastasis, the intake of cisplatin and cetuximab drugs, and the analysis of overall survival (OS) and progression-free survival (PFS) which were performed using the Kaplan-Meier method.

Purpose/Objective. A phase II clinical trial evaluating the feasibility and outcome of treating locally advanced head and neck squamous cell carcinoma (HNSCC) with accelerated radiotherapy, the hypoxic modifier nimorazole and weekly cisplatin. Material and methods. A total of 227 patients with stage III or IV HNSCC of the larynx, oropharynx, hypopharynx, or oral cavity where included between January 2007 and December 2010. The prescribed radiotherapy (RT) dose was 66-68 Gy in 2 Gy fractions, 6 F/W. The hypoxic radiosensitiser nimorazole was given orally at a dose of 1200 mg/m2 before each fraction. Concomitant cisplatin (40 mg/m2) i.v. was given once a week for a maximum of six cycles. Outcome data were evaluated in terms of loco-regional tumour control (LRC), event-free survival (EFS) and overall survival (OS). Morbidity data were evaluated based on the DAHANCA routine registration. Human papillomavirus (HPV)-status was estimated by immunohistochemical staining of p16. Results. Included were 178 (78%) men and 49 (22%) women with a median age of 57 years. All except five patients received RT as prescribed. At least five series of cisplatin was given to 164 (72%) of the patients, and 149 patients (66%) received the full dose of nimorazole. The five-year actuarial LRC, EFS and OS rates were 80%, 67% and 72%, respectively. The LRC rates according to site were: oropharynx: 88%, larynx: 77%, hypopharynx 72% and oral cavity 49%, respectively. HPV/p16 staining was obtained in 141 of the 150 oropharyngeal cancers. Of these, 112 (79%) were p16 pos and 29 (21%) were p16 neg. LRC for the p16 neg oropharyngeal cancers was poorer than for the p16 pos (74% vs. 91%; p = 0.02). Tube feeding during treatment was necessary for 146 (64%) patients. At 12 months this number was reduced to 6%. Conclusion. The treatment was tolerable in this cohort of locally advanced HNSCC patients. Acute and late toxicity was comparable to similar studies of chemoradiotherapy, and the outcome superior to the data reported in the literature. This strongly indicates that RT of advanced head and neck cancer must include as well hypoxic modification, accelerated fractionation as chemoradiotherapy to yield optimal outcome.

Objective. To evaluate from a planning point of view the dose distribution of adaptive radiation dose escalation in head and neck squamous cell carcinoma (HNSCC) using 18F-Fluoroazomycin arabinoside (FAZA) positron emission tomography/computed tomography (PET-CT). Material/methods. Twelve patients with locally advanced HNSCC underwent three FAZA PET-CT before treatment, after 7 fractions and after 17 fractions of a carboplatin-5FU chemo-radiotherapy regimen (70 Gy in 2 Gy per fraction over 7 weeks). The dose constraints were that every hypoxic voxel delineated before and during treatment (newborn hypoxic voxels) should receive a total dose of 86 Gy. A median dose of 2.47 Gy per fraction was prescribed on the hypoxic PTV defined on the pre-treatment FAZA PET-CT; a median dose of 2.57 Gy per fraction was prescribed on the newborn voxels identified on the first per-treatment FAZA PET-CT; a median dose of 2.89 Gy per fraction was prescribed on the newborn voxels identified on the second per-treatment FAZA PET-CT. Results. Ten of 12 patients had hypoxic volumes. Six of 10 patients completed all the FAZA PET-CT during radiotherapy. For the hypoxic PTVs, the average D50% matched the prescribed dose within 2% and the homogeneity indices reached 0.10 and 0.12 for the nodal PTV 86 Gy and the primary PTV 86 Gy, respectively. Compared to a homogeneous 70 Gy mean dose to the PTVs, the dose escalation up to 86 Gy to the hypoxic volumes did not typically modify the dose metrics on the surrounding normal tissues. Conclusion. From a planning point of view, FAZA-PET-guided dose adaptive escalation is feasible without substantial dose increase to normal tissues above tolerance limits. Clinical prospective studies, however, need to be performed to validate hypoxia-guided adaptive radiation dose escalation in head and neck carcinoma. [ABSTRACT FROM AUTHOR]

Background. Chemotherapy and targeted drugs are important tools in the treatment of malignant diseases. A number of the planned treatments are cancelled late which is a great challenge for the clinic to minimize in order to prevent the risk for misused resources. The aim of this study was to analyze the frequency and reasons for late (<48 hours) cancellations and also to get an overview of all intravenous medical anti-cancer treatment at the clinic. Material and methods. During four weeks in October 2010 all patients with intravenously administered chemotherapy and/or targeted drugs were registered at the Department of Oncology, Karolinska University Hospital. The survey comprehends the vast majority of all such treatment for solid tumors in adult patients in the Stockholm region with two million inhabitants. All bookings and late cancellations including their reasons were recorded. Diagnoses, treatment indication, line of treatment and survival, in particular short term survival, were analyzed. Results. Almost 3000 bookings for 1460 patients were included and 13% were cancelled late. Patient detoriation was the dominating cause for late cancellation in patients with palliative treatment (59%), while hematological toxicity was most common in the adjuvant group (42%). The most common treatment indication was palliative (62%). Of the palliative treatments, 95% where given in the first to third treatment line. Breast cancer (31.9%) and colorectal cancer (29.9%) were the two most common diagnoses. Seventy-one patients (4.9%) died within two months after the treatment. Conclusion. A more careful selection and monitoring of the patients might reduce the number of late cancellations due to patient detoriation. To record performance status (PS) as a routine for all patients might be helpful in that process. If the number of late cancellations could be reduced, resources at the clinic could be used more efficiently. [ABSTRACT FROM AUTHOR]

Purpose. Limited data are available to guide neoadjuvant treatment of borderline resectable (BRPC) and locally advanced (LAPC) pancreatic cancer. Material and methods. We updated our institutional outcomes with a neoadjuvant chemotherapy and stereotactic body radiotherapy (SBRT) approach. An IRB-approved analysis was performed of all BRPC and LAPC patients treated with our departmental treatment protocol. After staging, medically fit patients underwent chemotherapy for 2-3 months, with regimen at the discretion of the treating medical oncologist. Patients then received SBRT delivered in five consecutive daily fractions with median total radiation doses of 30 Gy to tumor and 40 Gy dose painted to tumor-vessel interfaces. This was followed by restaging imaging for possible resection. Overall survival (OS), event free survival (EFS), and locoregional control (LRC) rates were estimated and compared by Kaplan-Meier and log-rank methods. Results. We identified 159 patients, 110 BRPC and 49 LAPC, with 14.0 months median overall follow-up. The resection and margin negative (R0) rate for BRPC patients who completed neoadjuvant therapy was 51% and 96%, respectively. Estimated median OS was 19.2 months for BRPC patients and 15.0 months for LAPC patients (p = 0.402). Median OS was 34.2 months for surgically resected patients versus 14.0 months for unresected patients (p < 0.001). Five of 21 (24%) LAPC patients receiving FOLFIRINOX chemotherapy underwent R0 resection. In LAPC, FOLFIRINOX recipients underwent R0 resection more often than other chemotherapy recipients (5 of 21 vs. 0 of 28, p = 0.011). There was a trend for improved survival in those resected LAPC patients (p = 0.09). For those not undergoing resection, one year LRC was 78%. Any grade ≥ 3 potentially radiation-related toxicity rate was 7%. Conclusions. These data underscore the feasibility, safety, and effectiveness of neoadjuvant SBRT and chemotherapy for BRPC and LAPC.

Background. A planning study investigated whether reduced target volumes defined on FDG-PET/CT during radiotherapy allow total dose escalation without compromising normal tissue tolerance in patients with esophageal cancer. Material and methods. Ten patients with esophageal squamous cell carcinoma (SCC), candidate to curative-intent concomitant chemo-radiotherapy (CRT), had FDG-PET/CT performed in treatment position, before and during (Day 21) radiotherapy (RT). Four planning scenarios were investigated: 1) 50 Gy total dose with target volumes defined on pre-RT FDG-PET/CT; 2) 50 Gy with boost target volume defined on FDG-PET/CT during RT; 3) 66 Gy with target volumes from pre-RT FDG-PET/CT; and 4) 66 Gy with boost target volume from during-RT FDG-PET/CT. Results. The median metabolic target volume decreased from 12.9 cm3 (minimum 3.7-maximum 44.8) to 5.0 cm3 (1.7-13.5) (p = 0.01) between pre- and during-RCT FDG-PET/CT. The median PTV66 was smaller on during-RT than on baseline FDG-PET/CT [108 cm3 (62.5-194) vs. 156 cm3 (68.8-251), p = 0.02]. When total dose was set to 50 Gy, planning on during-RT FDG-PET/CT was associated with a marginal reduction in normal tissues irradiation. When total dose was increased to 66 Gy, planning on during-RT PET yielded significantly lower doses to the spinal cord [Dmax = 44.1Gy (40.8-44.9) vs. 44.7Gy (41.5-45.0), p = 0.007] and reduced lung exposure [V20Gy = 23.2% (17.3-27) vs. 26.8% (19.7-30.2), p = 0.006]. Conclusion. This planning study suggests that adaptive RT based on target volume reduction assessed on FDG-PET/CT during treatment could facilitate dose escalation up to 66 Gy in patients with esophageal SCC.

Background. Primary central nervous system lymphoma (PCNSL) is a rare brain tumour with a dismal prognosis. Several phase II studies with high-dose methotrexate-based regimens have shown promising early results, but in all hospital-based data published so far, the disease outcome is poor. Material and methods. We performed a hospital-based retrospective analysis to evaluate the long-term results of the Nordic type of Bonn chemotherapy regimen in PCNSL patients. The study included 54 patients with newly diagnosed PCNSL who received chemotherapy with curative intent as their first-line treatment. Results. We found promising response rates, 76% of the patients achieving CR and 22% patients achieving PR, with corresponding two-year EFS 53% and OS 76%. However, with longer follow-up a constant pattern of relapses was observed with only one patient remaining in primary remission after 60 months. Discussion. The finding suggests that basic biological differences exist between PCNSL and systemic diffuse large B-cell lymphoma and there is a need for consolidation or maintenance therapy after achieving a remission in patients with PCNSL.

Background. Chemotherapy with taxanes and platinum compounds has resulted in substantial survival benefits both in adjuvant and metastatic settings. However, as a side effect, such chemotherapy may cause peripheral neuropathy (CIPN) which may result in discontinuation of treatment, and if it persists after treatment completion, has a negative impact on quality of life (QoL). Results. Symptoms of CIPN are sensory, like pain, numbness, and tingling, typically located in the hands and feet. For oxaliplatin, there is an acute form of CIPN, resulting in paraesthesias in the mouth and throat during or shortly after the infusion triggered by exposure to cold. Risks factors for CIPN include preexisting neuropathy, either from treatment with other neurotoxic agents, or from comorbid conditions. The incidence of CIPN is related to dose per cycle, cumulative dose, and duration of infusion. While cisplatin-induced neuropathy is irreversible, CIPN induced by taxanes may persist for several years in about 30% of patients. Evidence from the literature is suggestive that CIPN is likely to be negatively associated with QoL. No agents have been identified to be recommended for the prevention of CIPN. For treatment of CIPN, the best available data supports a moderate recommendation for treatment with duloxetine and evidence is inconclusive regarding the use of tricyclic antidepressants (such as nortriptyline), gabapentin, and a compounded topical gel containing baclofen, amitriptyline HCL, and ketamine. Conclusion. Research is still needed to predict which patients are at high risk of developing CIPN during treatment and in whom CIPN will persist after completion of chemotherapy.

Purpose. Before, during and after autologous hematopoietic stem cell transplantation (HD-ASCT) patients suffer from significant loss of physical function, and experience multiple complications during and after hospitalization. Studies regarding safety and feasibility of physical exercise interventions for patients undergoing treatment with HD-ASCT are missing. Methods. Forty patients referred to HD-ASCT treatment, suffering from multiple myeloma, lymphoma or amyloidosis aged 23-70 years were enrolled in a prospective longitudinal study. The study consisted of a home-based exercise program for use in the ambulatory setting and supervised exercise sessions Monday to Friday for 30-40 minutes during admission. Safety of the exercise program and physical tests were assessed by using a weekly questionnaire and report of inadvertent incidences. Adherence to the home-based exercise program was reported by using a patient diary, weekly questionnaire and count of daily attendance in supervised sessions during hospital stay. Data collection was scheduled shortly after diagnosis, admission, discharge and eight weeks after discharge. Success criteria were: no severe adverse events in relation to exercise program and assessments; performance of three days of physical exercises during ambulatory period and hospital stay and 150 minutes of weekly physical activity. Results. Of the 25 patients who completed the exercise program during the ambulatory period prior to HD-ASCT a mean weekly attendance to home exercises of 5.3 (± 2.8) days and a median weekly physical activity of 240 (± 153.8) minutes was found. During hospital stay the median attendance was 9 (± 3.9) days of 10 (± 6.9) possible. Two months after discharge the patients reported a median weekly physical activity of 360 (2745.5) minutes. No severe adverse events in relation to the exercise program or assessments were reported. Conclusion. Based on the enrolled number of patients the physical exercise intervention for patients undergoing HD-ASCT seems promising regarding feasibility and safety. [ABSTRACT FROM AUTHOR]

Background. Anxiety and depressive symptoms are common among cancer survivors. Studies of a possible association with social position have had divergent results. We examined these associations, social position being measured by education, in Danish cancer survivors approximately two years after diagnosis. Material and methods. People aged over 18, living in Denmark and registered for a first cancer in the Danish National Patient Registry between 1 May and 31 August 2010 were contacted; 4346 returned a questionnaire shortly after diagnosis, and 2568 were followed up in 2012. Age, sex and cancer site were derived from the registry; all other information was self-reported, with that on education from the 2010 questionnaire and responses to the Hospital Anxiety and Depression Scale from the 2012 questionnaire. General linear models were used, with adjustment for demographic factors, cancer-specific factors, and comorbidity. Results. The study population consisted of 1667 people (response rate, 51%). The mean symptom scores were 4.34 (SD 3.77) for anxiety and 2.94 (SD 3.25) for depression. People with medium and higher education had slightly higher anxiety symptom scores (mean differencemedium = 0.41, 95% CI 20.07; 0.88, mean differencehigher = 0.19, 95% CI 20.27; 0.65). Depressive symptom scores were slightly elevated for people with medium education and reduced for those with higher education (mean differencemedium = 0.34, 95% CI 20.07; 0.75, mean differencehigher = 20,11, 95% CI 20.50; 0.29). Female sex, smoking-related cancers and chemotherapy were significantly associated with higher scores for both anxiety and depressive symptoms, but somatic comorbidity and mental disorders at the time of treatment were most strongly, significantly associated with elevated anxiety and depressive symptom scores. Conclusion. No overall significant differences in anxiety or depressive symptom scores were found with length of education. Previous mental disorders and somatic comorbidity are the strongest indicators of higher levels of anxiety and depressive symptoms. [ABSTRACT FROM AUTHOR]

Background. Treatment of testicular germ cell cancer constitutes a major success story in modern oncology. Today, the vast majority of patients are cured by a therapeutic strategy using one or more highly effective components including surgery (orchiectomy), radiotherapy and/or chemotherapy. However, the excellent cancer-specific survival comes at considerable costs, as individuals with a history of germ cell cancer experience serious long-term complications, including markedly increased risk of cardiovascular morbidities and premature cardiovascular death. The factors responsible, as well as their mode of action, are not fully understood and there is a lack of knowledge concerning optimal evidence-based long-term follow-up strategies. Results. Here, we present the growing body of evidence suggesting that germ cell cancer patients as a consequence of the different treatment components, are subjected to toxicities, which individually, and synergistically, can cause physiological impairments leading to sub-clinical or clinical cardiovascular disorders (i.e. the 'multiple-hit hypothesis'). Furthermore, we discuss the efficacy and utility of structured exercise training to ameliorate treatment-induced cardiovascular dysfunction to prevent premature onset of clinical cardiovascular disease in germ cell cancer survivors, with a view towards highlighting future directions of exercise-based survivorship research in the germ cell cancer setting. Conclusion. As exercise training may have the potential to ameliorate and/or reverse long-term cardiovascular disease sequelae in germ cell cancer survivors, a strong rationale exists for the promotion of exercise oncology research in this setting, in order to provide exercise recommendations for optimal germ cell cancer survivorship.

Backgrounds. Eribulin is a non-taxane, microtubule dynamics inhibitor approved for the treatment of patients with metastatic breast cancer (MBC) in Europe in March 2011. Material and methods. For the purpose of an internal quality control, all patients with MBC treated with eribulin at Karolinska University Hospital were registered in a database. Clinical data were collected retrospectively for patients that were registered by August 2012 and safety and efficacy of eribulin were evaluated. Treatment toxicity including fatigue, neurotoxicity and infection was graded according to CTCAE v4.0. Objective response to treatment was investigated using routinely performed radiological assessments. When only clinical assessments were made, the evaluation of the treating physician was used. Furthermore, the efficacy of eribulin was investigated in different tumor subtypes. Results. Forty-eight patients who received at least one cycle of eribulin were identified. Most patients were heavily pretreated with a median of 3 (range 1-7) previous chemotherapy lines prior to eribulin. Median patient age was 56 years (range 35-74). At the end of the analysis, 23 patients were alive and two were still treated with eribulin. No hypersensitivity reactions and no toxic deaths were seen. Fatigue grade 3-4 was observed in three patients (6.3%). One patient experienced grade 4 neurotoxicity. Grade 3-4 neutropenia was documented in 18.8%, and three patients were treated for a grade 3 infection. Interestingly, three individuals developed Herpes zoster reactivation. One patient responded to treatment with complete remission, while 33.3% had a partial response. 48% of all patients had a clinical benefit (objective response or stable disease for more than six months). Conclusions. Eribulin administered outside of a clinical trial in patients with advanced breast cancer was safe and well tolerated. A clinical benefit was seen in half of the cases. No statistically significant differences in objective response or survival were observed between histopathological subgroups. [ABSTRACT FROM AUTHOR]

Background. Chemotherapy-induced peripheral neuropathy (CIPN) is a dose-limiting side effect of oxaliplatin which can negatively influence quality of life. We aimed to study the influence of cumulative dose, dose schedule and dose reductions of adjuvant oxaliplatin on long-term severity and prevalence of CIPN among colorectal cancer (CRC) survivors. Material and methods. In total 207 patients, diagnosed with CRC between 2000 and 2009 who underwent adjuvant treatment with oxaliplatin, were included. They completed the EORTC QLQ-CIPN20 2-11 years after diagnosis. Data on oxaliplatin administration and acute neuropathy during treatment were extracted from the medical files. Subscales were analyzed with analysis of covariance and neuropathy symptoms with logistic regression analysis. Results. Patients who received cumulative oxaliplatin dose of ≥ 842 mg/m2 had a significantly worse EORTC QLQ-CIPN20 sensory score compared to those who received a low cumulative dose of < 421 mg/m2 (mean 19 vs. 8; p = 0.02). They more often reported tingling toes/feet (13% vs. 2%, respectively; p = 0.01). Dose intensity and time delay did not influence the occurrence of CIPN. Patients receiving a dose reduction because of neuropathy (N = 50) reported a significantly worse sensory score at very similar cumulative doses, than those who did not receive a dose reduction because of neuropathy (N = 96) (mean 21 vs. 15; p = 0.01). Conclusion. Cumulative dose of oxaliplatin is associated with long-term CIPN. The risk of developing long-term CIPN could only be reduced by decreasing the cumulative dose, whereas delay probably is not beneficial. Patients receiving a dose reduction because of acute neuropathy are still at risk of developing long-term CIPN. Future studies should focus on identifying patients who are at risk of developing CIPN.
