Purpose Angiogenesis is a crucial phenomenon in the development and progression of breast cancer (BC), but the clinical significance of angiogenesis-related proteins in metastatic BC remains unknown. This study investigates the prognostic value of vascular endothelial growth factor receptors 1, 2, 3 (VEGFR1, VEGFR2, VEGFR3) as well as vascular endothelial growth factors A and C (VEGFA and VEGFC) in metastatic BC patients treated with trastuzumab-based regimens.Materials and Methods Two hundred female patients were included. Protein and mRNA expression of the studied angiogenesis-related factors were evaluated by immunohistochemistry and quantitative polymerase chain reaction, respectively.Results High expression of VEGFA, VEGFC, VEGFR1, VEGFR2, and VEGFR3 in the tumor cells was observed in 43.5%, 24.2%, 36%, 29.5%, and 43%, respectively. Stromal elements expressed high levels of VEGFA, VEGFC, VEGFR1, VEGFR2, and VEGFR3 in 78.9%, 93.3%, 90.7%, 90.2%, and 74.8% of tumors with available data. High tumor cell expression of VEGFR1 was a favorable prognosticator for survival among patients with human epidermal growth factor receptor 2 (HER2)–positive tumors (hazard ratio [HR], 0.55; p=0.013). A trend towards longer progression-free survival was detected univariately for patients with HER2-negative tumors and high expression of VEGFR2 (HR, 0.60; p=0.059).Conclusion VEGFR1 and VEGFR2 seem to have significant prognostic value in BC patients with metastatic disease treated with trastuzumab-based regimens.

BackgroundAs management and prevention strategies against COVID-19 evolve, it is still uncertain whether prior exposure to immune checkpoint inhibitors (ICIs) affects COVID-19 severity in patients with cancer.MethodsIn a joint analysis of ICI recipients from OnCovid (NCT04393974) and European Society for Medical Oncology (ESMO) CoCARE registries, we assessed severity and mortality from SARS-CoV-2 in vaccinated and unvaccinated patients with cancer and explored whether prior immune-related adverse events (irAEs) influenced outcome from COVID-19.FindingsThe study population consisted of 240 patients diagnosed with COVID-19 between January 2020 and February 2022 exposed to ICI within 3 months prior to COVID-19 diagnosis, with a 30-day case fatality rate (CFR30) of 23.6% (95% CI 17.8 to 30.7%). Overall, 42 (17.5%) were fully vaccinated prior to COVID-19 and experienced decreased CFR30(4.8% vs 28.1%, p=0.0009), hospitalization rate (27.5% vs 63.2%, pOverall, 38 patients (15.8%) experienced at least one irAE of any grade at any time prior to COVID-19, at a median time of 3.2 months (range 0.13–48.7) from COVID-19 diagnosis. IrAEs occurred independently of baseline characteristics except for primary tumor (p=0.0373) and were associated with a significantly decreased CFR30(10.8% vs 26.0%, p=0.0462) additionally confirmed by the IPTW-fitted multivariable analysis (aOR 0.47, 95% CI 0.33 to 0.67). Patients who experienced irAEs also presented a higher median absolute lymphocyte count at COVID-19 (1.4 vs 0.8 109 cells/L, p=0.0098).ConclusionAnti-SARS-CoV-2 vaccination reduces morbidity and mortality from COVID-19 in ICI recipients. History of irAEs might identify patients with pre-existing protection from COVID-19, warranting further investigation of adaptive immune determinants of protection from SARS-CoV-2.

Gastric cancer is the fifth most common neoplasm worldwide with high rates of mortality. Afatinib, a low molecular, irreversible potent inhibitor of ErbB trans-membrane receptor family, has shown promising results according to preclinical and phase I clinical trial data when combined with chemotherapy. We aimed at evaluating the safety and efficacy of the combination of cisplatin, 5FU with afatinib in molecularly unselected patients with advanced gastric cancer.Patients with locally advanced or metastatic gastric/gastroesophageal junction adenocarcinoma received first line combination therapy of cisplatin, 5FU and afatinib every 21 days, followed by afatinib maintenance monotherapy. The primary endpoint was the Objective Response Rate (ORR); secondary endpoints included Overall Survival (OS), Progression Free Survival (PFS) and the safety profile. Unplanned exploratory analysis of HER2 and tumor mutational profile was performed.Among 55 patients (ITT population) enrolled, 19 (34.5%) achieved an objective tumor response; stable disease was observed in 16 patients (29.1%) and progressive disease in 10 patients (18.2%). The ORR in the per protocol population (PP) was 42.9%. Within a median follow-up of 56 months, the median PFS and OS in the ITT population was 5.0 and 8.7 months, respectively. Seven of the 47 HER2 informative cases carried HER2 positive tumors whileThe combination of cisplatin/5FU with afatinib did not surpass the benchmarks of efficacy of the contemporary therapeutic regimens that are being applied for the treatment of patients with advanced gastric cancer. However, the observed efficacy and the improved safety profile support that our administration schedule may be further investigated to overcome toxicity problems when integrating afatinib to cytotoxic chemotherapy.NCT01743365.

With the advent of immunotherapy and with the expanding spectrum of malignancies treated with immunomodulatory agents, a new kind of adverse events has come under the spotlight. Clinicians have to be aware of immune-related adverse events and their clinical manifestations. Immunotherapy has been strongly associated with endocrinopathies, gastrointestinal, pulmonary, cutaneous, and renal toxicities but the incidence of rheumatologic adverse events is lower compared to the aforementioned systems. Dermatomyositis is an autoimmune myopathy which has been correlated to underlying evident or occult malignancies. Apart from its characteristic symptoms and signs, the presence of specific antibodies such as anti-transcriptional intermediary factor 1γ (anti-TIF 1γ) usually supports the diagnosis of paraneoplastic nature of the disease. However, a solid distinction between paraneoplastic syndrome and immune-related adverse event is still missing and remains to be elucidated. We here present a case of dermatomyositis in a male patient who underwent four cycles of combined ipilimumab and nivolumab immunotherapy. This is, to our knowledge, the first case of dermatomyositis following combined immune checkpoint inhibition therapy.

Acquired hemophilia is a rare autoimmune bleeding disorder related to the production of autoantibodies that inhibit clotting factor VIII or IX. The underlying cause can be autoimmune disease, malignancy, pregnancy, or medications, but it is most commonly idiopathic. Here we present the case of an 81-year-old patient with locoregionally relapsed periampullary carcinoma who presented with soft tissue hematoma and an abnormally elevated activated partial thromboplastin time (aPTT) in the presence of a normal prothrombin time. A diagnosis of acquired hemophilia was established. The patient was managed with immunosuppressive prednisone and cyclophosphamide plus immunoglobulin G. He also received a cycle of chemotherapy with gemcitabine and oxaliplatin, because the underlying malignancy was the cause of the bleeding disorder. Care was complicated by neutropenia and nosocomial fever, but the patient eventually showed signs of clinical stability, while the aPTT decreased 2-fold. The patient was successfully discharged from the hospital and continued treatment in outpatient care.

International audience; Simple Summary There have been huge improvements in both vaccination and the management of COVID-19 in patients with cancer. In addition, different variants may be associated with different presentations. Therefore, we examined whether indicators of the severity of COVID-19 in patients with cancer who present to hospital varied during different waves of the pandemic and we showed that these indicators remained predictive. We validated that the COVID-19 Risk in Oncology Evaluation Tool (CORONET), which predicts the severity of COVID-19 in cancer patients presenting to hospital, performed well in all waves. In addition, we examined patient outcomes and the factors that influence them and found that there was increased vaccination uptake and steroid use for patients requiring oxygen in later waves, which may be associated with improvements in outcome. Patients with cancer have been shown to have increased risk of COVID-19 severity. We previously built and validated the COVID-19 Risk in Oncology Evaluation Tool (CORONET) to predict the likely severity of COVID-19 in patients with active cancer who present to hospital. We assessed the differences in presentation and outcomes of patients with cancer and COVID-19, depending on the wave of the pandemic. We examined differences in features at presentation and outcomes in patients worldwide, depending on the waves of the pandemic: wave 1 D614G (n = 1430), wave 2 Alpha (n = 475), and wave 4 Omicron variant (n = 63, UK and Spain only). The performance of CORONET was evaluated on 258, 48, and 54 patients for each wave, respectively. We found that mortality rates were reduced in subsequent waves. The majority of patients were vaccinated in wave 4, and 94% were treated with steroids if they required oxygen. The stages of cancer and the median ages of patients significantly differed, but features associated with worse COVID-19 outcomes remained predictive and did not differ between waves. The CORONET tool performed well in all waves, with scores in an area under the curve (AUC) of >0.72. We concluded that patients with cancer who present to hospital with COVID-19 have similar features of severity, which remain discriminatory despite differences in variants and vaccination status. Survival improved following the first wave of the pandemic, which may be associated with vaccination and the increased steroid use in those patients requiring oxygen. The CORONET model demonstrated good performance, independent of the SARS-CoV-2 variants.

Background Alternative splicing of vascular endothelial growth factor A (VEGFA) results in VEGFAxxxb antiangiogenic isoforms that fail to activate angiogenesis. Bevacizumab, widely used in patients with metastatic colorectal cancer (CRC), binds both VEGFA and VEGFAxxxb isoforms. Patients and Methods Formalin-fixed, paraffin-embedded primary tumors from metastatic CRC patients treated with first-line FOLFIRI (leucovorin, 5-fluorouracil, irinotecan, and oxaliplatin) + bevacizumab (n = 285) or FOLFIRI only (n = 75) were collected. The relative expression of VEGFA121a, 121b, 145a, 145b, 165a, and 165b was assessed with custom TaqMan-MGB assays and quantitative PCR. Results At a median follow-up of 101.5 months, left-sided primary CRC was a favorable prognosticator (median survival, 29.2 vs. 18.2 months; P = .015). Positive high VEGFA145b was an unfavorable factor for progression-free survival (PFS; hazard ratio [HR] = 1.66; 95% confidence interval [CI], 1.13-2.44; P = .009) in patients who received FOLFIRI + bevacizumab, without prognostic significance in FOLFIRI-only patients (HR = 0.70; 95% CI, 0.34-1.44; P = .33). The adverse effect on PFS of 145b was more pronounced in patients with right-sided colon cancer (HR = 2.62; 95% CI, 1.35-5.12; P = .005), especially in those who received bevacizumab (HR = 2.85; 95% CI, 1.31-6.21; P = .008). In patients with right-sided colon primary tumors, isoform 121b correlated with inferior PFS (HR = 1.73; 95% CI, 0.94-3.18; P = .076) and overall survival (OS; HR = 2.0; 95% CI, 1.08-3.72; P = .028). In patients with left-sided primary tumors, positive high 165b correlated with superior PFS (HR = 0.76; 95% CI, 0.59-0.99; P = .044) and OS (HR = 0.68; 95% CI, 0.52-0.90; P = .006). At multivariate analysis, right-sided primary tumor was associated with inferior PFS (HR = 1.28; 95% CI, 1.00-1.64), while 145b consistently retained predictive significance for lack of benefit in PFS with bevacizumab (HR = 1.71; 95% CI, 1.16-2.53). Multivariate analysis for OS showed that VEGFA165b expression was favorable in patients with left-sided but unfavorable in patients with right-sided primary tumors (Pinteraction Conclusion The antiangiogenic isoform VEGFA145b messenger RNA may predict resistance to bevacizumab. Differences in biological relevance and prognostic significance of various VEGFA isoforms were found for right- versus left-sided primary tumors.

Prognostic and predictive biomarkers are being studied for the diagnosis and treatment of breast cancer. The present study retrospectively assessed the mRNA expression of HER family receptor ligands and of other potential prognostic biomarkers and their association with time to progression (TTP), survival and clinicopathological characteristics in patients with metastatic breast cancer (MBC) treated with trastuzumab. A total of 145 tumour tissue samples were analysed. mRNA expression analysis of the transcripts of interest was performed and the association of these markers with selected clinicopathological parameters was examined. HER2 status was centrally re-evaluated. Only 67.6% of patients were truly HER2-positive according to the central HER2 re-evaluation. Heparin binding epidermal growth factor (EGF)-like growth factor, transforming growth factor β1 (TGFB1) and thyroid hormone receptor α (THRA) mRNA expression was higher in HER2-positive patients (P=0.026, P

Simple Summary Non-small cell lung cancer (NSCLC) accounts for approximately 85% of lung cancer cases, with few patients carrying driver mutations in the gene encoding for epidermal growth factor receptor (EGFR). Advances in translational research have established EGFR tyrosine kinase inhibitors (TKIs) as the standard first-line therapy for NSCLC patients with activating EGFR mutations. The aim of our observational study was to assess the frequency of T790M acquired resistance and predictors of its presence, in patients with EGFR-mutated locally advanced or metastatic NSCLC who have progressed in the first-line EGFR-TKI treatment setting with first- or second-generation TKIs and have undergone molecular testing in tissue and/or plasma biopsy. The study highlights the challenges of performing tissue re-biopsy in routine care settings, which can lead to patients considered non-eligible for certain therapies from which they can benefit, and merits further actions from the healthcare community, in order to establish re-biopsy as a standard procedure. Abstract Background: Real-world data on the molecular epidemiology of EGFR resistance mutations at or after progression with first- or second-generation EGFR-TKIs in patients with advanced NSCLC are lacking. Methods: This ongoing observational study was carried out by 23 hospital-based physicians in Greece. The decision to perform cobas® EGFR Mutation Test v2 in tissue and/or plasma at disease progression was made before enrollment. For patients with negative/inconclusive T790M plasma-based results, tissue re-biopsy could be performed. Results: Ninety-six (96) eligible patients were consecutively enrolled (median age: 67.8 years) between July-2017 and September-2019. Of the patients, 98% were tested upon progression using plasma and 2% using tissue/cytology biopsy. The T790M mutation was detected in 16.0% of liquid biopsies. Tissue re-biopsy was performed in 22.8% of patients with a T790M-negative plasma result. In total, the T790M positivity rate was 21.9%, not differing between patients on first- or second-generation EGFR-TKI. Higher (≥2) ECOG performance status and longer (≥10 months) time to disease progression following EGFR-TKI treatment initiation were associated with T790M positivity. Conclusions: Results from plasma/tissue-cytology samples in a real-world setting, yielded a T790M positivity rate lower than previous reports. Fewer than one in four patients with negative plasma-based testing underwent tissue re-biopsy, indicating the challenges in routine care settings.

BACKGROUND: Src, CDKN1B, and JAK2 play a crucial role in the coordination of cell signaling pathways. In the present study, we aim to investigate the prognostic significance of these biomarkers in HER2-positive metastatic breast cancer (MBC) patients treated with trastuzumab (T). METHODS: Formalin-fixed paraffin-embedded tumor tissue samples from 197 patients with HER2-positive MBC treated with T were retrospectively collected. All tissue samples were centrally assessed for ER, PgR, Ki67, HER2, and PTEN protein expression; EGFR gene amplification; PI3KCA mutational status; and tumor-infiltrating lympocytes density. Src, CDKN1B, and JAK2 mRNA expression was evaluated using quantitative reverse transcription-polymerase chain reaction. RESULTS: Only 133 of the 197 patients (67.5%) were found to be HER2-positive by central assessment. CDKN1B mRNA expression was strongly correlated with Src (rho = 0.71) and JAK2 (rho = 0.54). In HER2-positive patients, low CDKN1B conferred higher risk for progression [hazard ratio (HR) = 1.58, 95% confidence interval (CI) 1.08-2.32, P = .018]. In HER2-negative patients, low Src was associated with longer survival (HR = 0.56, 95% CI 0.32-0.99, P = .045). Upon multivariate analyses, only low CDKN1B and JAK2 mRNA expression remained unfavorable factors for PFS in de novo and relapsed (R)-MBC patients, respectively (HR = 2.36, 95% CI 1.01-5.48, P = .046 and HR = 1.76, 95% CI 1.01-3.06, P = .047, respectively). CONCLUSIONS: Low CDKN1B and JAK2 mRNA expressions were unfavorable prognosticators in a cohort of T-treated MBC patients. Our results suggest that CDKN1B and JAK2, if validated, may serve as prognostic factors potentially implicated in T resistance, which seems to be associated with distinct pathways in de novo and R-MBC.

PURPOSE To better understand the European Society for Medical Oncology-Magnitude of Clinical Benefit Scale version 1.1 (ESMO-MCBS v1.1) and the ASCO Value Framework Net Health Benefit score version 2 (ASCO-NHB v2), ESMO and ASCO collaborated to evaluate the concordance between the frameworks when used to assess clinical benefit attributable to new therapies. METHODS The 102 randomized controlled trials in the noncurative setting already evaluated in the field testing of ESMO-MCBS v1.1 were scored using ASCO-NHB v2 by its developers. Measures of agreement between the frameworks were calculated and receiver operating characteristic curves used to define thresholds for the ASCO-NHB v2 corresponding to ESMO-MCBS v1.1 categories. Studies with discordant scoring were identified and evaluated to understand the reasons for discordance. RESULTS The correlation of the 102 pairs of scores for studies in the noncurative setting is estimated to be 0.68 (Spearman’s rank correlation coefficient; overall survival, 0.71; progression-free survival, 0.67). Receiver operating characteristic curves identified thresholds for ASCO-NHB v2 for facilitating comparisons with ESMO-MCBS v1.1 categories. After applying pragmatic threshold scores of 40 or less (ASCO-NHB v2) and 2 or less (ESMO-MCBS v1.1) for low benefit and 45 or greater (ASCO-NHB v2) and 4 to 5 (ESMO-MCBS v1.1) for substantial benefit, 37 discordant studies were identified. Major factors that contributed to discordance were different approaches to evaluation of relative and absolute gain for overall survival and progression-free survival, crediting tail of the curve gains, and assessing toxicity. CONCLUSION The agreement between the frameworks was higher than observed in other studies that sought to compare them. The factors that contributed to discordant scores suggest potential approaches to improve convergence between the scales.

BACKGROUND/AIM: PTEN-loss and PIK3CA mutations have been addressed as markers of PI3K activation in breast cancer. We evaluated these markers in early high-risk breast cancer (EBC) focusing on PTEN immunohistochemistry (IHC) issues, particularly in HER2-positive disease. MATERIALS AND METHODS: We examined PTEN-loss and PIK3CA mutations in 1265 EBC patients treated with adjuvant chemotherapy within two clinical trials. Two different methods for the evaluation of PTEN IHC were used, one upfront binary (loss; no-loss) and the other initially multi-scale allowing for the classification of "grey zone" tumors with low and very low PTEN protein expression. RESULTS: PTEN-loss (33.4% and 22.1%, depending on the IHC method) and PIK3CA mutations (29.6%) were associated with ER/PgR/HER2-negative and ER/PgR-positive disease, respectively. Concordance of the two IHC methods was moderate (Cohen's kappa 0.624). PTEN-loss discrepancy and intra-tumor heterogeneity concerned "grey zone" tumors that were prevalent among HER2-positive cancers. PTEN-loss independently conferred higher risk for relapse and death. Compared to single PIK3CA mutations,single PTEN-loss was independently associated with increased risk for relapse and death. Depending on the evaluation method, in HER2-positive cancer, PTEN-loss was without- or of marginal unfavorable prognostic significance. CONCLUSION: In EBC, PTEN-loss is an independent predictor of poor outcome. When occurring singly, PTEN-loss and PIK3CA mutations have opposite prognostic impact. In HER2-positive disease, assessment of PTEN-loss by IHC appears unreliable and the marker is without clear prognostic significance.

Background: Patients with cancer are at increased risk of severe COVID-19, but have heterogeneous presentations and outcomes. Decision-making tools for hospital admission, severity prediction and increased monitoring for early intervention are critical. We sought to identify features of COVID-19 in cancer patients predicting severe disease and build a decision-support online tool; COVID-19 Risk in Oncology Evaluation Tool (CORONET). Methods: Patients with active cancer (stage I-IV) and laboratory confirmed COVID-19 presenting to hospitals worldwide were included. Discharge (within 24hrs), admission (≥24hrs inpatient), oxygen requirement (O2) and death were combined in a 0-3 point severity scale. Association of features with outcome were investigated using Lasso regression and Random Forest (RF) combined with SHapley Additive exPlanations (SHAP). RF was further validated in 4 cohorts, split by geography. The CORONET model was then examined in the entire cohort to build an online CORONET decision-support tool. Admission and severe disease thresholds were established through pragmatically defined cost functions. Findings: The dataset comprised 920 patients; median age 70 (range 5-99), 56% males, 44% females, 81% solid vs. 19% haematological cancers. In derivation, RF demonstrated superior performance over Lasso with lower mean squared error (0.801 vs. 0.807) and was selected for development. During validation, RF achieved mean AUROC 0.77, 0.80 and 0.75 for prediction of admission, O 2 and death, respectively. Using the entire cohort, CORONET cut-offs for admission and mortality of 1.0 and 2.3 were established. The CORONET decision support tool recommended admission for 95% of patients eventually requiring oxygen and 97% of those who died. SHAP explanations revealed National-Early-Warning-Score-2, C-reactive protein and albumin were the most important features contributing to COVID-19 severity prediction in patients with cancer at time of hospital presentation. Interpretation: CORONET, a decision-support tool validated in healthcare systems worldwide can aid admission decisions and predict COVID-19 severity in patients with cancer. Funding Information: R.

In this chapter, we aimed to provide an evidence-based guidance on posttreatment surveillance for the recurrence of several common cancers. We found that there is a lack of strong evidence, as most of the studies are retrospective. Furthermore, many studies were conducted in an era before the emergence of novel effective treatment options and diagnostic methods. Currently, most recommendations on surveillance come from experts’ consensus.

Background CUPISCO is an ongoing randomized phase II trial (NCT03498521) comparing molecularly guided therapy versus platinum‐based chemotherapy in patients newly diagnosed with “unfavorable” cancer of unknown primary (CUP). Materials and Methods Patients with an unfavorable CUP diagnosis, as defined by the European Society of Medical Oncology (ESMO), and available cancer tissue for molecular sequencing are generally eligible. Potential patients with CUP entering screening undergo a review involving reference histopathology and clinical work‐up by a central eligibility review team (ERT). Patients with “favorable” CUP, a strongly suspected primary site of origin, lack of tissue, or unmet inclusion criteria are excluded. Results As of April 30, 2020, 628 patients had entered screening and 346 (55.1%) were screen failed. Screen fails were due to technical reasons (n = 89), failure to meet inclusion and exclusion criteria not directly related to CUP diagnosis (n = 89), and other reasons (n = 33). A total of 124 (35.8%) patients were excluded because unfavorable adeno‐ or poorly differentiated CUP could not be confirmed by the ERT. These cases were classified into three groups ineligible because of (a) histologic subtype, such as squamous and neuroendocrine, or favorable CUP; (b) evidence of a possible primary tumor; or (c) noncarcinoma histology. Conclusion Experience with CUPISCO has highlighted challenges with standardized screening in an international clinical trial and the difficulties in diagnosing unfavorable CUP. Reconfirmation of unfavorable CUP by an ERT in a clinical trial can result in many reasons for screen failures. By sharing this experience, we aim to foster understanding of diagnostic challenges and improve diagnostic pathology and clinical CUP algorithms. Implications for Practice A high unmet need exists for improved treatment of cancer of unknown primary (CUP); however, study in a trial setting is faced with the significant challenge of definitively distinguishing CUP from other cancer types. This article reports the authors' experience of this challenge so far in the ongoing CUPISCO trial, which compares treatments guided by patients’ unique genetic signatures versus standard chemotherapy. The data presented will aid future decision‐making regarding diagnosing true CUP cases; this will have far‐reaching implications in the design, execution, and interpretation of not only CUPISCO but also future clinical studies aiming to find much‐needed treatment strategies., Effective therapeutic regimens are lacking for patients with cancers of unknown primary (CUP). This article reports the clinic‐pathological challenges associated with diagnosis of unfavorable CUP in the CUPSICO trial and suggests refinements for diagnostic algorithms.

Simple Summary Although VEGF-A is well characterized as the principal player of cancer angiogenesis, new data on the interplay with other components of the tumor microenvironment emerge. Here we review the effect of VEGF-A on cancer cells and immune cells as well as investigative and established combinational therapies of anti-angiogenic agents with immune checkpoint inhibitors. We thus elaborate the scientific rationale behind the development of these novel combinational approaches. Abstract Angiogenesis has long been considered to facilitate and sustain cancer growth, making the introduction of anti-angiogenic agents that disrupt the vascular endothelial growth factor/receptor (VEGF/VEGFR) pathway an important milestone at the beginning of the 21st century. Originally research on VEGF signaling focused on its survival and mitogenic effects towards endothelial cells, with moderate so far success of anti-angiogenic therapy. However, VEGF can have multiple effects on additional cell types including immune and tumor cells, by directly influencing and promoting tumor cell survival, proliferation and invasion and contributing to an immunosuppressive microenvironment. In this review, we summarize the effects of the VEGF/VEGFR pathway on non-endothelial cells and the resulting implications of anti-angiogenic agents that include direct inhibition of tumor cell growth and immunostimulatory functions. Finally, we present how previously unappreciated studies on VEGF biology, that have demonstrated immunomodulatory properties and tumor regression by disrupting the VEGF/VEGFR pathway, now provide the scientific basis for new combinational treatments of immunotherapy with anti-angiogenic agents.

Immune checkpoint inhibitors, such as anti-cytotoxic T-lymphocyte–associated antigen-4 and anti-programmed death-1, are a type of cancer immunotherapy approved for late-stage malignancy treatment. However, such therapies often induce immune-related adverse events. During anti-programmed death-1 blockade therapy, the most commonly reported adverse effects are skin toxicities, such as psoriasis—a chronic immune-mediated inflammatory disorder affecting the skin. We present the clinical characteristics of flared psoriasis in one patient under anti-programmed death-1 therapy who was diagnosed with T2N2M0/IIIB squamous lung carcinoma with a history of psoriasis for the past 5 years, exacerbated after the first cycle of nivolumab. After the third cycle, the extensive skin plaques necessitated treatment cessation. Following the discontinuation of anti-programmed death-1 treatment, skin lesions were treated locally. Possibly, anti-programmed death-1 immunotherapy can trigger immune-mediated diseases, such as psoriasis. Physicians should be alert to immune-related adverse events. Continuation or permanent cessation of treatment depends on the severity and reversibility of immune-related adverse events.

ESMO clinical practice guidelines (CPGs) have been developed to provide recommendations for the standard of care according to the highest quality evidence-based data (EBD). European Society for Medical Oncology (ESMO) is also conducting consensus conference (CC) activities to provide answers to crucial questions of clinical relevance, which are then formulated as recommendations. To be successful, a CPG has to be implemented in daily practice, a multistep process which can be affected by CPG features (complexity, poor access), external factors (social norms, health carers workload, local and national guidelines) and physician personal factors (knowledge and attitudes), but mostly relies on dissemination and physician awareness.1 2 Compliance of physicians with national and/or international guidelines has emerged as an important criterium to assess quality of care. Studies to evaluate the compliance with international guidelines, like National Comprehensive Cancer Network (NCCN), have been performed in patients with breast cancer and in elderly patients with stage III colon cancer3 4 by auditing patients medical records. In 2014, the three main European societies active in gynaecological oncology (ESMO, European Society of Gynaecological Oncology (ESGO), European SocieTy for Radiotherapy and Oncology (ESTRO)) performed a CC in endometrial cancer (EC), the most common gynaecological cancer in developed countries, for the treatment of which a multidisciplinary approach is needed.5 To evaluate the clinical implementation of the recommendations 5 years after the endometrial CC, the three societies conducted a survey, the results of which were reported at ESMO 2020.6 The survey was based on three clinical cases, one by each society. Each case consisted of five questions, each with five possible answers, but only one correct according to CC recommendations and adequate for the specific clinical situation. The selected topics were the management of early stage endometrioid EC, of high-grade serous histotype and of poorly differentiated stage …

Background We explored the clinical significance of tumor genotypes and immunophenotypes in non-metastatic colorectal cancer (CRC). Methods In primary tumors (paraffin blocks) from 412 CRC patients treated with adjuvant chemotherapy, we examined pathogenic mutations (panel NGS; 347 informative); mismatch repair (MMR) immunophenotype (360 informative); and CD8+ lymphocyte density (high – low; 412 informative). The primary outcome measure was disease-free survival (DFS). Results We evaluated 1713 pathogenic mutations (median: 3 per tumor; range 0-49); 118/412 (28.6%) tumors exhibited high CD8+ density; and, 40/360 (11.1%) were MMR-deficient.

BACKGROUND/AIM The efficacy of gemcitabine-based chemotherapy in locally advanced/metastatic biliary tract carcinoma is limited. The aim of this trial was to assess the activity of a novel gemcitabine-pazopanib combination in such patients. PATIENTS AND METHODS In this phase II, multicenter trial, patients with histologically/cytologically confirmed biliary tract carcinoma, previously untreated for advanced disease, received 1000 mg/m2 of gemcitabine on days 1 and 8 every 21 days and 800 mg of pazopanib once daily continuously for 8 cycles, followed by pazopanib maintenance. The primary endpoint was objective response rate (ORR). RESULTS A total of 29 patients (median age; 69 years) were enrolled between June 2013 and March 2018. The ORR was 13.8% in the intent-to-treat and 19.1% in the per protocol population. The median progression-free and overall survival were 6.3 and 10.4 months, respectively. CONCLUSION The low response rate precludes further testing of the combination in patients with biliary tract carcinoma.

The use of port central venous catheters (CVCs) for chemotherapeutical use has seen exponential growth over the last decades. However, port CVC misplacement may lead to catheter malfunction (such as partial or total catheter blockade), which might be complicated by thrombosis and catheter superinfections, and these in turn may lead to pulmonary embolism and bloodstream infections. The overall occurrence of port CVC misplacement is up to 6%; nonetheless, port CVC misplacement may occur in up to 67% of patients with early CVC dysfunction (occurring within three months of catheter insertion). Thereafter, the prompt evaluation of catheter position among patients with first-trimester CVC dysfunction is extremely important. The aim of the present manuscript is to support medical oncologists, haematologists, and clinicians in timely suspicion and recognition of port CVC misplacement among patients with early CVC dysfunction. Radiological educational iconographic materials that will assist a prompt estimate of port-CVC dislocation are provided.

Background Trastuzumab is a monoclonal antibody against HER2-positive breast cancer. Despite improving the natural history of the disease, there is a number of patients who are resistant to it, whereas all patients will eventually develop resistance and disease will progress. Inconsistent preclinical data show that the IGF-R pathway may contribute to either de novo or acquired resistance to trastuzumab. Materials and methods In total, 227 trastuzumab-treated metastatic breast cancer patients were evaluated for IGF-1, IGF-1R, GLP-1R, Akt1, Akt2 Akt3 mRNA expression, and IGF-1Rα, IGF-1Rβ, IGF-2R protein expression. Results Only 139 patients were truly HER2-positive by central assessment. Among HER2-positive patients, high Akt2 and GLP-1R mRNA expression showed a trend towards higher and lower risk of progression, respectively (HR=1.83, 95%CI=0.90-3.72, p=0.094 and HR=0.62, 95%CI=0.36-1.06, p=0.079), while high Akt1 and GLP-1R mRNA expression presented a trend towards unfavorable survival (HR=1.67, 95%CI=0.93-2.99, p=0.086 and HR=1.67, 95%CI=0.94-2.96, p=0.080). Among HER2-negative patients, high GLP-1R mRNA expression and negative stromal IGF-1Rβ protein expression showed a trend towards worse survival (HR=2.31, 95%CI=0.87-6.13, p=0.094 and HR=2.03, 95%CI=0.94-4.35, p=0.071, respectively). In the multivariate analyses, HER2-positive patients with high Akt1 and GLP-1R mRNA expression had a worse survival (HR=1.86, 95%CI=1.01-3.43, p=0.045 and HR=1.83, 95%CI=0.99-3.41, p=0.055, respectively). Conclusion This study revealed a crosstalk between the IGF-R pathway and HER2. There was evidence that high Akt1 and GLP-1R mRNA expression might affect survival among HER2-positive metastatic breast cancer patients treated with trastuzumab.

Background: At the height of the first wave of the SARS-COV-2 pandemic, ESMO mobilized to accelerate research for the understanding of COVID-19 in cancer patients (pts). ESMO CoCARE is an international collaborative registry-based, cohort study, gathering real-world data and information from healthcare professionals about the natural history, treatment and outcomes of COVID-19 in cancer pts. Methods: ESMO CoCARE captures information on pts with any solid or hematologic malignancy (including cancer survivors free of disease for ≥5 years) presenting with a COVID-19 diagnosis in any of the participating centers. Data collected since 06/2020 include demographics, cancer characteristics and status, co-morbidities, COVID-19 clinical features, course, management and outcome. Factors influencing COVID-19 severity (hospitalization +/- ICU support needed) and recovery are investigated using multivariable logistic regression with backward elimination method. The study is ongoing. Results: The current analysis includes 1551 registered pts (19 countries;87% pts from 23 European centers, 7% and 6% pts from 5 Northern African and 7 Asian centers), with COVID-19 diagnosis as of 11/03/2021. Median age was 64 years, with the majority female (52%), cancer stage III/IV (58%), and on active cancer treatment (60%). 65% had severe COVID-19 requiring hospitalization, with 11% receiving intensive care. In multivariable analysis, in addition to demographics (male gender, older age, other ethnicity than Caucasian, lower BMI), co-morbidities and symptomatic COVID-19, severe disease was associated to higher ECOG PS (Odds Ratio (OR)2 vs 0=5.9, OR1 vs 0=2.1), hematological malignancies (OR hemvs solid =2.0), and active/progressive cancer status (OR progressivevs no evidence of disease =1.6). 98% of pts with mild disease recovered, as opposed to only 70% of those with severe disease. Cancer stage was an additional prognostic factor for recovery (ORI/II vs IV =3.4). Conclusions: Demographic characteristics, type and status of cancer, and symptomatology of COVID-19 increase the probability of severe disease, while advanced cancer stage is also associated with the risk of death.

Background: The ESMO Magnitude of Clinical Benefit Scale (ESMO-MCBS) version 1.0 (v1.0) was published in May 2015 and was the first version of a validated and reproducible tool to assess the magnitude of clinical benefit from new cancer therapies. The ESMO-MCBS was designed to be a dynamic tool with planned revisions and updates based upon recognition of expanding needs and shortcomings identified since the last review.Methods: The revision process for the ESMO-MCBS incorporates a nine-step process: Careful review of critiques and suggestions, and identification of problems in the application of v1.0; Identification of shortcomings for revision in the upcoming version; Proposal and evaluation of solutions to address identified shortcomings; Field testing of solutions; Preparation of a near-final revised version for peer review for reasonableness by members of the ESMO Faculty and Guidelines Committee; Amendments based on peer review for reasonableness; Near-final review by members of the ESMO-MCBS Working Group and the ESMO Executive Board; Final amendments; Final review and approval by members of the ESMO-MCBS Working Group and the ESMO Executive Board.Results: Twelve issues for revision or amendment were proposed for consideration; proposed amendments were formulated for eight identified shortcomings. The proposed amendments are classified as either structural, technical, immunotherapy triggered or nuanced. All amendments were field tested in a wide range of studies comparing scores generated with ESMO-MCBS v1.0 and version 1.1 (v1.1).Conclusions: ESMO-MCBS v1.1 incorporates 10 revisions and will allow for scoring of single-arm studies. Scoring remains very stable; revisions in v1.1 alter the scores of only 12 out of 118 comparative studies and facilitate scoring for single-arm studies.

BACKGROUND: Prevention of bone metastases is a major issue for breast cancer patients, as it would improve quality of life in a population where long survival is anticipated. PATIENTS AND METHODS: Early breast cancer patients, who had been treated with anthracycline-based chemotherapy within two randomized trials, were included in the study. We evaluated, by quantitative reverse transcription–polymerase chain reaction, 819 formalin-fixed paraffin-embedded tumor tissue samples for mRNA expression of RANK, OPG, and RANKL, as well as their ratios, for potential prognostic significance for the development of bone metastases and also for disease-free survival (DFS) and overall survival. RESULTS: Median age was 52.7 years, whereas 54.2% of the patients were postmenopausal and 78.3% estrogen receptor/progesterone receptor positive. After a median follow-up of 119.9 months, 226 patients (27.6%) had died and 291 patients (35.5%) had disease progression. Low mRNA expression of RANKL was associated with postmenopausal status and greater number of positive lymph nodes (P = .002 and P

Aim: The aim of this study was to evaluate the mRNA expression pattern of growth- and survival-related genes and assess their prognostic significance in patients with advanced pancreatic cancer. Patients and Methods: In total, 98 patients were included in this retrospective translational research study and were evaluated for Kirsten rat sarcoma viral oncogene homolog (KRAS) mutational status, and v-akt murine thymoma viral oncogene homolog 1 (AKT1), AKT serine/threonine kinase 2 (AKT2), AKT serine/threonine kinase 3 (AKT3), cyclin D1 (CCND1), epidermal growth factor receptor (EGFR), mitogen-activated protein kinase 1 (MAPK1), hepatocellular growth factor receptor (MET), avian myelomatosis viral oncogene homolog (MYC), nuclear factor kappa B subunit 1 (NFKb1), phosphatase and tensin homolog (PTEN) and mechanistic target of rapamycin (FRAP1) genes mRNA expression. Among these patients, 73 received first-line gemcitabine combined with erlotinib (N=57) or gefitinib (N=16). Results: KRAS mutation did not correlate with mRNA gene expression. Unsupervised hierarchical clustering according to mRNA gene expression successfully distinguished four prognostically distinct groups of tumors. Overexpression of all genes was associated with best prognosis, while suppression or heterogeneous expression patterns of the examined genes were associated with expression patterns of growth- and survival-related genes, classifying pancreatic tumors into distinct groups with possibly different outcomes.

Licence holders of a new medical agent who apply for marketing authorisation in Europe have two choices: They may either apply to a national health authority (which limits authorisation to the authority’s country) or choose the centralised procedure with the European Medicines Agency (EMA) to apply for authorisation for all countries belonging to the European Union (EU) as well as Liechtenstein, Iceland and Norway. For anticancer drugs, as well as several other categories, the central authorisation approach through EMA is compulsory since 2005.1 On application, EMA will launch a content-defined and timeline-defined verifying procedure (figure 1), which will lead to a recommendation. The agency has no legislative or other decisive power. EMA’s recommendation will then be submitted to the European Commission, which will take the legal binding decision for marketing authorisation, based on EMA’s recommendation. This is not synonymous but a precondition for pricing and reimbursement, as the latter remains within the competence of member states and their national and/or regional health authorities (with requirements, procedures and decisions varying according to each country). Having obtained marketing authorisation by the European Commission following EMA’s recommendation, the drug’s marketing authorisation holder (MAH) must thus proceed applying individually for pricing and reimbursement in each country he wishes to commercialise the drug. Figure 1 Procedure and timelines for first drug marketing approval by EMA. CHMP, Committee for Medicinal Products for Human Use.

Owing to its advantages over prior relevant technologies, massive parallel or next-generation sequencing (NGS) is rapidly evolving, with growing applications in a wide range of human diseases. The burst in actionable molecular alterations in many cancer types advocates for the practicality of using NGS in the clinical setting, as it permits the parallel characterization of multiple genes in a cost- and time-effective way, starting from low-input DNA. In advanced clinical practice, the oncological management of colorectal cancer requires prior knowledge of KRAS, NRAS, and BRAF status, for the design of appropriate therapeutic strategies, with more gene mutations still surfacing as potential biomarkers. Tumor heterogeneity, as well as the need for serial gene profiling due to tumor evolution and the emergence of novel genetic alterations, have promoted the use of liquid biopsies—especially in the form of circulating tumor DNA (ctDNA)—as a promising alternative to tissue molecular analysis. This review discusses recent studies that have used plasma NGS in advanced colorectal cancer and summarizes the clinical applications, as well as the technical challenges involved in adopting this technique in a clinically beneficial oncological practice.

Tumor-infiltrating lymphocytes (TILs) and their subsets contribute to breast cancer prognosis. We investigated the prognostic impact of CD3+, CD8+ and FOXP3+ TILs in patients with early intermediate/high-risk breast cancer treated with adjuvant anthracycline-based chemotherapy within two randomized trials conducted by our Group. We examined 1011 patients (median follow-up 130.9 months) and their tumors for total, stromal (s) and intratumoral (i) CD3, CD8 and FOXP3 lymphocyte density (counts/mm2) on tissue-microarray cores by immunohistochemistry. Morphological sTIL density on whole H&E-stained sections was also evaluated. The majority of TILs were CD3+. Total CD3 and CD8, sCD3 and sCD8, iCD3 and iCD8, sFOXP3 and iFOXP3 were strongly correlated (Spearman’s rho values > 0.6). High individual lymphocytic subsets and sTIL density were strongly associated with high tumor grade, higher proliferation and HER2-positive and triple-negative tumors (all p values

Despite the progress in cancer diagnostics and therapeutics where the use of gene expression profiling has elucidated underlying molecular mechanisms, cancer of unknown primary (CUP) still remains an unexplored area. Being a heterogeneous, often aggressive disease, it poses a significant clinical challenge. The overall worldwide incidence is 3%–5% with the majority of patients presenting with extensive metastatic deposits, ranking relatively high among causes of death attributed to neoplasms. Although thorough clinical examination, laboratory tests, radiology examinations and detailed pathology analysis are performed, the primary site may not be identified.1 Patients with CUP have clinical and radiological findings compatible with metastatic disease in the presence of a cytological or pathological diagnosis of malignancy. Efforts should be made for obtaining a rather generous amount of tumour specimen in order to proceed with the pathology examination. The pathology report should contain morphology review and immunohistochemistry studies in order to confirm malignant diagnosis and exclude melanomas, sarcomas, lymphomas and germ cell tumours. After establishing epithelial histology, staining for CK7 and CK20 may limit the differential diagnosis to few possible sites of tumour origin. Targeted, judicious application of additional immunohistochemical markers (CEA, PSA, CDX-2, TTF-1, ER, PR, AFP, β-HG, PLAP, HMB45) may further enhance the diagnostic output and should be applied according to the patient’ s clinical, radiology and pathology data. Most commonly, CUPs are poorly or moderately differentiated carcinomas or adenocarcinomas, less often squamous cell carcinomas, carcinomas with neuroendocrine differentiation, undifferentiated neoplasms. It is vital to not miss a diagnosis of curable malignancies such as germ cell tumours or lymphomas especially when poorly differentiated/undifferentiated histology is present.2 3 Apart from meticulous pathology review, all patients should undergo thorough physical examination, basic blood and biochemistry analyses and chest/abdominopelvic CT scans. In cases of female patients, bilateral digital mammography should not be omitted in …

Background The clinical relevance of mismatch repair (MMR) status in patients with nonmetastatic cancer across tumour types remains unclear. Our goal was to investigate the prognostic role of MMR deficiency in patients with stage I-III colorectal and endometrial cancer.Methods Patients with nonmetastatic colorectal and endometrial cancer with tumour tissue available for analysis were identified through the Hellenic Cooperative Oncology Group (HeCOG)’s tumour repository. Patients had been referred to Departments of Medical Oncology affiliated with HeCOG. MMR protein expression was evaluated by immunohistochemistry. The primary outcome measure was overall survival (OS).Results From May 1990 to September 2012, 1158 patients with nonmetastatic colorectal (N = 991) and endometrial cancer (N = 167) were identified (median age: 64 years, men: 544). All patients with colorectal and 109 (65%) with endometrial cancer had received adjuvant treatment. MMR deficiency was observed in 114 (11.5%) of colorectal and 80 (47.9%) of endometrial tumours. More commonly deficient proteins were PMS2 (69 patients, 7%) and MLH1 (63 patients, 6.5%) in colorectal cancer and MSH2 (58 patients, 34.7%) in endometrial cancer. Colorectal MMR-deficient (dMMR) tumours were more likely to be right sided (65 % dMMR vs 27 % proficient MMR, pMMR; p < 0.001), high grade (31% vs 15%, χ2, p < 0.001) and with a mucinous component (64% vs 42%, p < 0.001). Endometrial dMMR tumours were more often of endometrioid histology (51.4 % endometrioid vs 20 % serous/clear cell, p = 0.020). Compared with MMR proficiency, MMR deficiency was associated with improved OS in patients with endometrial cancer (HR = 0.38, 95% CI 0.20 to 0.76, p = 0.006), but not in patients with colorectal cancer (HR = 0.73, 95% CI 0.49 to 1.09, p = 0.130). After adjusting for age, stage and grade, MMR deficiency maintained its favourable prognostic significance in patients with endometrial cancer (HR = 0.42, 95% CI 0.20 to 0.88, p = 0.021).Conclusions DMMR was associated with improved outcomes in patients with nonmetastatic endometrial cancer, but not in patients with nonmetastatic colorectal cancer who received adjuvant chemotherapy.

BackgroundAnalysis of circulating tumor nucleic acids in plasma of Non-Small Cell Lung Cancer (NSCLC) patients is the most widespread and documented form of "liquid biopsy" and provides real-time information on the molecular profile of the tumor without an invasive tissue biopsy.MethodsLiquid biopsy analysis was requested by the referral physician in 121 NSCLC patients at diagnosis and was performed using a sensitive Next Generation Sequencing assay. Additionally, a comparative analysis of NSCLC patients at relapse following EGFR Tyrosine Kinase Inhibitor (TKIs) treatment was performed in 50 patients by both the cobas and NGS platforms.ResultsAt least one mutation was identified in almost 49% of the cases by the NGS approach in NSCLC patients analyzed at diagnosis. In 36 cases with paired tissue available a high concordance of 86.11% was observed for clinically relevant mutations, with a Positive Predictive Value (PPV) of 88.89%. Furthermore, a concordance rate of 82% between cobas and the NGS approach for the EGFR sensitizing mutations (in exons 18, 19, 21) was observed in patients with acquired resistance to EGFR TKIs, while this concordance was 94% for the p.T790M mutation, with NGS being able to detect this mutation in three 3 additional patients.ConclusionsThis study indicates the feasibility of circulating tumor nucleic acids (ctNA) analysis as a tumor biopsy surrogate in clinical practice for NSCLC personalized treatment decision making. The use of new sensitive NGS techniques can reliably detect tumor-derived mutations in liquid biopsy and provide clinically relevant information both before and after targeted treatment in patients with NSCLC. Thus, it could aid physicians in treatment decision making in clinical practice.

The CpG island methylator phenotype (CIMP) is a promising biomarker for irinotecan/5-fluorouracil/leucovorin chemotherapy for stage III colon cancer. In the present study, we evaluated whether CIMP is a prognostic biomarker for standard-of-care oxaliplatin-based adjuvant therapy.The HE6C/05 trial randomized 441 patients with stage II-III colorectal adenocarcinoma to adjuvant XELOX (capecitabine, oxaliplatin) or modified FOLFOX6 (5-fluorouracil, leucovorin, oxaliplatin). The primary and secondary objectives were disease-free and overall survival, respectively. CIMP status was determined using the DNA methylation status of CACNA1G, IGF2, NEUROG1, RUNX3, and SOCS1. Cox models were used to assess the association of CIMP with survival.Of the 293 available tumors, 28 (9.6%) were CIMP(+). On univariate Cox regression analysis, no significant differences in survival were observed between individuals with CIMP(+) versus CIMP(-) tumors. CIMP(+) tumors were more likely to be right-sided and BRAF mutant (χ(2), P .001). In the multivariate model, TNM stage II (vs. stage III) was associated with a reduced risk of relapse (hazard ratio [HR], 0.25; 95% confidence interval [CI], 0.11-0.55; Wald's P .001), and a colon primary located on the left side and earlier TNM stage were associated with a reduced risk of death (HR, 0.48; 95% CI, 0.28-0.81; P = .006; and HR, 0.22; 95% CI, 0.10-0.49; P .001, respectively).In the present exploratory analysis, CIMP did not appear to be a prognostic biomarker in oxaliplatin-treated patients with resected colorectal cancer.

Treatment of oncologic patients has progressed greatly the last few years with the development of immune checkpoint inhibitors (ICPIs). These drugs are associated with the immune system and, thus, may cause side effects of immune origin, the so called immune related adverse events (irAEs). Immune related AEs may actually affect all organs and systems and frequently resemble clinical entities commonly encountered in clinical practice. As ICPIs have improved both quality of life and life expectancy, clinicians of various specialties may need to deal with irAEs in their everyday practice. Therefore, they should be able to recognize them timely and treat them accordingly. Herein, we review the pathophysiology, clinical manifestations and treatment of irAEs.

The purpose of this study was to explore the efficacy and safety of everolimus administered as a first-line treatment in newly diagnosed patients with metastatic or inoperable gastroenteropancreatic neuroendocrine tumors (GEP NETs). This phase II, multicenter, single-arm study included patients with well-differentiated GEP NETs and a Ki67 <, 20%. Everolimus, at 10 mg/day, was administered until disease progression, 18 patients (72%) concomitantly received octreotide long-acting release (LAR), at 30 mg/month. The primary endpoint was the 15-month progression-free survival (PFS) rate. Twenty-five patients (grade 1: 11 patients, grade 2: 14 patients) were enrolled between August 2012 and October 2015. At a median follow-up of 58.1 months, the median PFS was 14.6 months, while the 15-month PFS rate was 48%, median overall survival had not been reached yet. Normal baseline chromogranin A (<, 4 nmol/l) confirmed a longer PFS (HR = 0.25, 95% CI 0.08&ndash, 0.77, p = 0.016). Seven patients (28%) achieved an objective response (one complete response and six partial responses) in a median of 2.6 months. Twenty-three grade 3&ndash, 4 events were recorded (14 patients). No fatal reactions occurred. This prospective phase II study unravels the notable activity of everolimus as a first-line treatment in patients with GEP NETS and contributes valuable information about the high activity of the combination of everolimus and octreotide LAR in this setting. Clinical trial information: NCT01648465.

COVID-19 pandemic challenges health system capacities in many countries. National healthcare services have to manage unexpected shortage of healthcare resources that have to be reallocated according to the principles of fair and ethical prioritisation, in order to maintain the highest levels of care to all patients, ensure the safety of patients and healthcare workers and save as many lives as possible. Beyond that, cancer care services have to pursue restructuring, following the same evidence-based dispositions. In this article, we propose guidance to the management of colorectal cancer during the pandemic, prioritised according to a three-tiered framework, based on expert clinical judgement and magnitude of benefit expected from specific interventions. Since the availability of resources for diagnostic procedures, surgery and postoperative care, systemic therapy and radiotherapy may differ, authors did separate prioritisation analyses. The impact of postponing or abrogating cancer interventions on outcomes according to a high, medium or low priority scale, is outlined and discussed. The implementation of healthcare services using telemedicine is explored: it reveals itself as functional and effective for limiting patients' need to travel to centres and thereby has the potential to reduce diffusion of severe acute respiratory syndrome coronavirus 2. Colorectal cancer demands a considerable amount of medical resources. Therefore, the redefinition of its diagnostic and therapeutic algorithms with a rigorous method is crucial in order to ensure the highest quality of continuum of care in the broader context of the pandemic and the challenged healthcare systems.

The prognosis of patients with advanced pancreatic cancer is dismal, and there is a need for novel and effective treatments. Tο determine the maximum tolerated dose (MTD) and dose-limiting toxicities (DLTs) of a novel gemcitabine (G) and temsirolimus (T) combination (phase I) and estimate the 6-month progression-free survival (PFS) in patients treated with the T + G combination (phase II). Eligible patients with histologically confirmed inoperable or metastatic pancreatic carcinoma (MPC) were entered into the trial. G was given bi-weekly and T weekly in a 4-week cycle. The first dose level was set at G 800 mg/m2 and T 10 mg. G was escalated in increments of 200 mg/m2 and T in increments of 5 mg until DLT was reached, and the recommended dose was used for the phase II part. Thirty patients were enrolled in the phase I component at the pre-planned six dose levels; one bilirubin DLT of grade III occurred at the first dose level. The MTD was established as the approved doses of both drugs. Fifty-five patients were entered into the phase II component. Median relative dose intensities administered in the first cycle were 0.75 for T and 0.99 for G. Grade 3-4 hematological toxicities were recorded in 87.3% of patients. The most common non-hematological adverse events were metabolic disorders (81.8%) followed by gastrointestinal disorders (63.6%). Median PFS was 2.69 months (95% CI 1.74-4.95) and median OS was 4.95 months (95% CI 3.54-6.85), while the 6-month PFS rate was 30.9%. Combination of G and T is feasible in patients with locally advanced or MPC with manageable side effects, but lacks clinical efficacy. The study was registered in the Australian New Zealand Clinical Trials Registry (ACTRN12611000643976).

Several studies support an important role of angiogenesis in breast cancer growth and metastasis. The main objectives of the study were to investigate the immunohistochemical expression of vascular endothelial growth factor (VEGF) family ligands (VEGF-A and VEGF-C) and receptors (VEGFR1, VEGFR2 and VEGFR3) in breast cancer and their associations with clinicopathological parameters, cancer subtypes/subgroups and patient outcome. Formalin-fixed paraffin-embedded tumor tissue samples were collected from early-stage breast cancer patients treated with anthracycline-based chemotherapy within a randomized trial. Immunohistochemistry was performed on serial 2.5 μm thick tissue sections from tissue microarray blocks. High VEGF-A, VEGF-C, VEGFR1, VEGFR2 and VEGFR3 protein expression was observed in 11.8% (N = 87), 80.8% (N = 585), 28.1% (N = 202), 64.6% (N = 359) and 71.8% (N = 517) of the cases, respectively.

Background Metastatic colorectal cancer represents a striking example of clonal heterogeneity and tumour evolution, which generates acquired resistance to therapy. Once hard to perform, the study of clonal heterogeneity is now significantly aided by the use of liquid biopsies. Method We herein report a case of a patient with colorectal cancer and serial development of multiple metastases which were all resected and genotyped. A rare point mutation was identified in the primary tumour (but not in any of the organ metastatic sites), as well as in the first and the last out of three consecutive liquid biopsies. The review of the literature offered some insight in the evolution of the patient’s tumour and general directions on how to interpret liquid biopsy results. Conclusions This patient case emphasises the need for large prospective studies designed to bridge liquid biopsy data with useful clinical endpoints, in order to optimally integrate this revolutionary tool in everyday practice.

This clinical trial assessed the efficacy and toxicity of panitumumab combined with oxaliplatin and capecitabine as first-line treatment in KRAS exon 2 wild-type metastatic colorectal cancer (mCRC) patients. Patients with exon 2 KRAS wild-type mCRC received panitumumab 9 mg/Kg, oxaliplatin 130 mg/m2, and capecitabine 2000 mg/m2 repeated every 3 weeks. The primary endpoint was objective response rate (ORR, minimum 42 responses). We retrospectively assessed mutations in genes implicated in CRC with massively parallel sequencing; ERBB2 and EGFR amplification with fluorescence in situ hybridization, and tumor-infiltrating lymphocyte density. Among 78 patients enrolled, 45 (57.7%) completed 6 cycles. Most common grade 3–4 toxicities were skin rash (19.2%), diarrhea (18%), and neuropathy (6.4%). Among 5 (6.4%) potentially treatment-related deaths, 2 (2.6%) were characterized toxic. Objective response occurred in 43 (55.1%) of the patients (complete 6.4% and partial response 48.7%; stable 17.9% and progressive disease 7.7%), while 3.8% were non-evaluable and 15% discontinued their treatment early. Additional mutations in KRAS/NRAS/BRAF were found in 11/62 assessable (18%) tumors. After 51 months median follow-up, median progression-free (PFS) was 8.1 and overall survival 20.2 months, independently of KRAS/NRAS/BRAF or PI3K-pathway mutation status. Patients with TP53 mutations (n = 34; 55%), as well as those with left colon primary tumors (n = 66; 85%), had significantly better PFS, also confirmed in multivariate analysis. Although the clinical trial met its primary endpoint, according to the current standards, the efficacy and tolerability of the drug combination are considered insufficient. Extended genotyping yielded interesting results regarding the significance of TP53 mutations. ClinicalTrials.gov identifier: NCT01215539, Registration date: Sep 29, 2010.

The efficacy and safety of the FOLFIRI (leucovorin, 5-fluorouracil, irinotecan, and oxaliplatin) regimen combined with aflibercept has not been studied in the first-line management of patients with metastatic colorectal cancer (mCRC).In the context of a prospective single-arm trial (NCT02129257), patients with mCRC received standard doses of a maximum of 12 cycles of FOLFIRI combined with aflibercept (4 mg/kg body weight delivered intravenously) every 2 weeks, followed by aflibercept maintenance. Endpoints were 12-month progression-free survival rate, efficacy, and toxicity.Seventy-three fit patients were enrolled onto the study between 2014 and 2016. Median relative dose intensities administered were 0.80 for irinotecan and 1.0 for aflibercept. The most common grade 3/4 adverse events were neutropenia (13 patients, 18%), febrile neutropenia (3 patients, 4%), diarrhea (11 patients, 15%), hypertension (19 patients, 26%), proteinuria (8 patients, 11%), infections (8 patients, 11%), and mucositis (6 patients, 8%), with no toxic deaths. The objective response rate was 46.6%, significantly associated with the presence of right-sided primary, synchronous metastases, and a relapse-free interval of 12 months (odds ratio = 3.00, 2.92, and 3.75 respectively, P ≤ .05). Intermediate infiltration by stromal core lymphocytes correlated with progression-free survival (hazard ratio = 0.40, [95% confidence interval (CI), 0.19-0.83], P = .014). At a median follow-up of 24.5 months, 12-month progression-free survival rate was 21.9% (median overall survival 20.9 months [95% CI, 16.6-29], median progression-free survival 8.4 months [95% CI, 7.4-9.3]).The FOLFIRI + aflibercept regimen is active and tolerable; however, it failed to improve historical benchmarks of efficacy in chemonaive patients with mCRC. Preliminary data hint that this regimen has cytoreductive activity in disease with adverse biology.

BACKGROUND: Data from two trials of panitumumab in metastatic colorectal cancer (mCRC) were retrospectively analysed to investigate the effects of primary tumour location on early-tumour shrinkage (ETS) and depth of response (DpR), and identify factors predicting long-term survival. METHODS: Patients with RAS wild-type mCRC from PRIME (NCT00364013) and PEAK (NCT00819780) were included. ETS was defined as a >= 30% reduction in the sum-of-the-longest-diameters of measurable target lesions at eight weeks. DpR was the maximum percentage change from baseline to nadir in patients with shrinkage. Univariate and multivariate logistic analyses of short-versus long-term survivor data were performed. RESULTS: A total of 435/559 (78%) patients had left-sided disease. Of these, a higher proportion of patients treated with panitumumab versus comparator achieved ETS (PRIME: 62% vs. 36%; PEAK: 58% vs. 41%); median DpR was also higher with panitumumab (PRIME: 59% vs. 49%; PEAK: 70% vs. 48%). In pooled analyses of the studies, more patients with right-sided disease achieved ETS if treated with panitumumab than comparator (39% vs. 29%). Panitumumab treatment consistently predicted long-term survival. CONCLUSIONS: First-line panitumumab was associated with improved ETS and DpR vs. comparator in patients with left-sided mCRC. ETS may identify a subgroup of patients with right-sided disease who might respond to panitumumab.

INTRODUCTION: Sarcomas are a rare and heterogeneous group of tumours of mesenchymal origin. Single agent pazopanib showed activity in a phase II clinical trial designed to screen various soft tissue sarcoma subtypes [10] and a phase III [11] clinical trial followed resulting in FDA approval in 2012 for use in metastatic soft tissue sarcoma exposed to prior chemotherapy. METHODS: We conducted an independent computerised review of PubMed and ScienceDirect database up to May 2015 using combinations of terms such as soft tissue sarcoma, pazopanib, STS ,VEGFR2, TKIs ,angiogenesis, advanced sarcoma treatment, targeted therapy for sarcoma AIM: Our aim was to explore the role of pazopanib in soft tissue sarcoma (STS) treatment, its mode of action, the clinical trials supporting its approval, safety and efficacy, how the product fits into the real world and its contribution to the development of targeted therapy for STS CONCLUSION: Pazopanib is a valid, innovative and cost-effective approach in the treatment of advanced pre-treated STS
