PURPOSE The study aimed to investigate strategies to prevent and treat cetuximab-induced skin reactions and their perceived effectiveness in patients with metastatic colorectal cancer (mCRC) and recurrent/metastatic squamous cell cancer of the head and neck (SCCHN). METHODS This open-label, prospective observational study was conducted in Switzerland. RESULTS A total of 125 patients were included (n = 91 mCRC, n = 34 SCCHN; mean age 63.3 years; 73.6% males). The frequency of acneiform rash grade ≥ 2 increased from 12.6% at week 2 to 21.7% at week 16. The proportion of patients who reported no skin reaction decreased from 75.6% at week 2 to 43.3% at week 16. The most frequently used skin products at any time of observation were moisturizing (77.6%), lipid-regenerating (56.8%) or urea-containing products (52%), systemic antibiotics (49.6%), and vitamin K1 cream (43.2%). There was no clear effectiveness pattern for all product classes: in given patients, either the product showed no effect at all or a moderate/strong effect, consistently over time. CONCLUSIONS A great variety of low-cost general skin care products were commonly used. According to physician's preference, systemic antibiotics and vitamin K1 cream are an appropriate approach to prevent or treat cetuximab-related skin toxicity.

Background First-line pembrolizumab monotherapy improves overall and progression-free survival in patients with untreated metastatic non-small-cell lung cancer with a programmed death ligand 1 (PD-L1) tumour proportion score (TPS) of 50% or greater. We investigated overall survival after treatment with pembrolizumab monotherapy in patients with a PD-L1 TPS of 1% or greater. Methods This randomised, open-label, phase 3 study was done in 213 medical centres in 32 countries. Eligible patients were adults (≥18 years) with previously untreated locally advanced or metastatic non-small-cell lung cancer without a sensitising EGFR mutation or ALK translocation and with an Eastern Cooperative Oncology Group (ECOG) performance status score of 0 or 1, life expectancy 3 months or longer, and a PD-L1 TPS of 1% or greater. Randomisation was computer generated, accessed via an interactive voice-response and integrated web-response system, and stratified by region of enrolment (east Asia vs rest of world), ECOG performance status score (0 vs 1), histology (squamous vs non-squamous), and PD-L1 TPS (≥50% vs 1-49%). Enrolled patients were randomly assigned 1:1 in blocks of four per stratum to receive pembrolizumab 200 mg every 3 weeks for up to 35 cycles or the investigator's choice of platinum-based chemotherapy for four to six cycles. Primary endpoints were overall survival in patients with a TPS of 50% or greater, 20% or greater, and 1% or greater (one-sided significance thresholds, p=0·0122, p=0·0120, and p=0·0124, respectively) in the intention-to-treat population, assessed sequentially if the previous findings were significant. This study is registered at ClinicalTrials.gov, number NCT02220894. Findings From Dec 19, 2014, to March 6, 2017, 1274 patients (902 men, 372 women, median age 63 years [IQR 57-69]) with a PD-L1 TPS of 1% or greater were allocated to pembrolizumab (n=637) or chemotherapy (n=637) and included in the intention-to-treat population. 599 (47%) had a TPS of 50% or greater and 818 patients (64%) had a TPS of 20% or greater. As of Feb 26, 2018, median follow-up was 12·8 months. Overall survival was significantly longer in the pembrolizumab group than in the chemotherapy group in all three TPS populations (≥50% hazard ratio 0·69, 95% CI 0·56-0·85, p=0·0003; ≥20% 0·77, 0·64-0·92, p=0·0020, and ≥1% 0·81, 0·71-0·93, p=0·0018). The median surival values by TPS population were 20·0 months (95% CI 15·4-24·9) for pembrolizumab versus 12·2 months (10·4-14·2) for chemotherapy, 17·7 months (15·3-22·1) versus 13·0 months (11·6-15·3), and 16·7 months (13·9-19·7) versus 12·1 months (11·3-13·3), respectively. Treatment-related adverse events of grade 3 or worse occurred in 113 (18%) of 636 treated patients in the pembrolizumab group and in 252 (41%) of 615 in the chemotherapy group and led to death in 13 (2%) and 14 (2%) patients, respectively. Interpretation The benefit-to-risk profile suggests that pembrolizumab monotherapy can be extended as first-line therapy to patients with locally advanced or metastatic non-small-cell lung cancer without sensitising EGFR or ALK alterations and with low PD-L1 TPS.

Background Breast cancer screening mammography is widespread in industrialised countries within the framework of public health program or opportunist form. Only few data exist on the comparison of effectiveness between organised and opportunistic screening. The aim of this study is to compare organised and opportunistic screening using population-based data from the Fribourg cancer registry, Switzerland. Methods We included all first primary breast adenocarcinoma diagnosed between 2006 and 2014 in women aged 50–69 years resident in the canton of Fribourg. We considered only breast cancer discovered by mammography screening. We compared patients, tumour characteristics and treatment modalities between breast cancer detected by the organised screening program versus opportunistic screening using logistic regression. Results Out of 989 patients diagnosed with breast cancer, 402 (40.6%) were diagnosed by organised and 205 (20.7%) by opportunistic screening. Women with breast cancer detected within the screening program were more likely to be from rural areas (P = 0.035) and lived less frequently in high favoured regions (P = 0.020). They presented more frequently in situ than invasive cancer (P = 0.022). For patients with invasive breast cancer, those detected by the program were less likely to undergo mastectomy (P = 0.06) and consequently, they were more likely to undergo radiation therapy (P = 0.003). Adjustment for area of residence and financial context of the region did not modify the results presented. Conclusions The present study reports an increased rate of detection of carcinoma in situ in organised screening program as compared to opportunistic screening mammographies, an indirect evidence of a higher radiologic sensitivity. Furthermore, the results show a trend towards more mastectomies among patients with breast cancer discovered after opportunistic than after organized mammography screening, reflecting lower treatment burden. Those results were independent of socio-economic factors which differed across screening groups.

Background: For patients with resectable stage IIIA(N2) non-small cell lung cancer (NSCLC) neoadjuvant chemotherapy with three cycles of cisplatin and docetaxel followed by surgery has been shown to yield a 1-year event-free survival (EFS) rate of 48% and is an accepted standard of care. Neoadjuvant PD-(L)1 inhibitors can result in high response rates in resectable NSCLC. Methods: Neoadjuvant treatment consisted of three cycles of cisplatin 100 mg/m 2 and docetaxel 85 mg/m 2 q3w followed by two cycles of durvalumab 750 mg q2w. Adjuvant durvalumab was continued for 1 year after surgery. The primary endpoint was 1-year EFS. The hypothesis for statistical considerations was an improvement of 1-year EFS from 48% to 65%. This trial is registered with ClinicialTrials.gov, NCT02572843. Findings: Sixty-eight patients were enrolled, 67 were included in the full analysis set. Radiographic response rate was 43·3% (95%CI: 31·2-56·0) after neoadjuvant chemotherapy (complete remission (CR): 2·9%, partial remission (PR): 40·3%, stable disease (SD): 44·8%) and 58·1% (95%CI: 44·8-70·5) after additional neoadjuvant immunotherapy (CR: 6·5%, PR: 51·6%, SD: 25·8%). Fifty-five patients were resected, of which 34 (61·8%) achieved a major pathological response (MPR; ≤10% viable tumour cells), and 10 (18·2%) amongst them a complete pathological response. Postoperative nodal down-staging (ypN0-1) was observed in 37 patients (67·3%). Fifty-one (92·7%) patients had an R0 resection. There was no significant effect of pre-treatment PD-L1 expression on MPR or nodal down-staging. In the entire study population, the 1-year EFS rate was 73·4% (90%CI: 62·7-81·5). Median EFS and overall survival were not reached after 28 months of median follow-up. Fifty-nine (88·1%) patients had an adverse event (AE) grade ≥3 including two fatal AEs that were not assessed to be treatment-related. Interpretation: This is thus far the largest report on perioperative PD-(L)1 inhibition in patients with resectable stage IIIA(N2) NSCLC. The addition of perioperative durvalumab to neoadjuvant chemotherapy is safe and exceeds historical data of chemotherapy alone with a high MPR and an encouraging 1-year EFS rate of 73·4%.

Introduction: Receptor activator of NF-kB ligand stimulates NF-kB-dependent cell signaling and acts as the primary signal for bone resorption. Retrospective analysis of a large trial comparing denosumab versus zoledronic acid in bone metastatic solid tumors suggested significant overall survival (OS) advantage for patients with lung cancer with denosumab (p = 0.01). The randomized open-label phase III SPLENDOUR trial was designed to evaluate whether the addition of denosumab to standard first-line platinum-based doublet chemotherapy improved OS in advanced NSCLC. Methods: Patients with stage IV NSCLC were randomized in a 1:1 ratio to either chemotherapy with or without denosumab (120 mg every 3-4 wks), stratified by the presence of bone metastases (at diagnosis), Eastern Cooperative Oncology Group performance status, histology, and region. To detect an OS increase from 9 to 11.25 months (hazard ratio [HR] = 0.80), 847 OS events were required. The trial closed prematurely owing to decreasing accrual rate. Results: A total of 514 patients were randomized, with 509 receiving one or more doses of the assigned treatment (chemotherapy: 252, chemotherapy-denosumab: 257). The median age was 66.1 years, 71% were men, and 59% were former smokers. Bone metastases were identified in 275 patients (53%). Median OS (95% confidence interval [CI]) was 8.7 (7.6-11.0) months in the control arm versus 8.2 (7.5-10.4) months in the chemotherapy-denosumab arm (HR = 0.96; 95% CI: 0.78-1.19; one-sided p = 0.36). For patients with bone metastasis, HR was 1.02 (95% CI: 0.77-1.35), whereas for those without, HR was 0.90 (95% CI: 0.66-1.23). Adverse events grade 3 or greater were observed in 40.9%, 5.2%, 8.7% versus 45.5%, 10.9%, 10.5% of patients. Conditional power for OS benefit was less than or equal to 10%. Conclusions: Denosumab was well-tolerated without unexpected safety concerns. There was no OS improvement for denosumab when added to chemotherapy in the intention-to-treat population and the subgroups with and without bone metastases. Our data do not provide evidence of a clinical benefit for denosumab in patients with NSCLC without bone metastases. (C) 2020 International Association for the Study of Lung Cancer.

TO THE EDITOR: Treatment of proteasome inhibitor (PI)–refractory multiple myeloma (MM) is challenging, with response rates of only 15% to 35% being achieved with next-generation drugs such as pomalidomide, carfilzomib, and daratumumab, alone or in combination.[1][1][⇓][2]-[3][3] The oral HIV

Autologous stem cell transplantation (ASCT) as part of the primary therapy in multiple myeloma (MM) is standard practice. In contrast, the role of a second ASCT (ASCT2) and subsequent lenalidomide maintenance for relapsed disease remains unclear. In this study, we analysed 86 consecutive MM patients with a first relapse after prior ASCT receiving either a second ASCT or conventional chemotherapy. After a median follow-up of 37.7 months since first relapse, 54 (62.8%) patients were still alive and 29 (33.7%) without progression. Sixty-one (71.0%) patients received ASCT2 and had better progression-free survival (PFS) (30.2 versus 13.0 mo; P = .0262) and overall survival (OS) rates (129.6 versus 33.5 mo; P = .0003) compared with 25 (29.0%) patients with conventional treatment. Patients relapsing later than 12 months after ASCT1 benefitted from a second ASCT with better PFS2 (P = .0179) and OS2 (P = .0009). Finally, lenalidomide maintenance after ASCT2 was associated with longer PFS (41.0 vs 21.6 mo; P = .0034) and better OS (not yet reached vs 129.6 mo; P = .0434) compared with patients without maintenance. Our data suggest that a second ASCT and lenalidomide maintenance given at first relapse in MM after prior ASCT are associated with better survival rates.

Chemotherapy with G-CSF is used to mobilize peripheral stem cells in multiple myeloma (MM) patients, with plerixafor as a rescue strategy for poorly mobilizing patients. Preclinical studies suggested that the nonsteroidal anti-inflammatory drug meloxicam enhances the mobilization of CD34+ cells. In this single-center study, we evaluated whether adding meloxicam to chemotherapy/G-CSF mobilization increases peripheral hematopoietic CD34+ cell levels and reduces the need of using plerixafor. We prospectively compared two consecutive cohorts of MM patients in first remission mobilized with G-CSF and non-myelosuppressive chemotherapy with vinorelbine or gemcitabine. The second cohort additionally received oral meloxicam. The cohorts comprised 84 patients without meloxicam (-M) and 66 patients with meloxicam (+M). Meloxicam was well tolerated and associated with similar hematologic engraftment after transplantation and equal survival rates. However, the meloxicam group had higher CD34+ cell levels on day 8 of the mobilization procedure (53 200 versus 35 600 CD34+ cells/mL; P=0.007), and fewer patients needed >1 collection day (+M: 6 (9%) patients versus -M: 16 (19%) patients; P=0.04). This resulted in reduced plerixafor administrations (+M: 7 (11%) patients versus -M: 18 (21%) patients; P=0.03) and less costs. Our data suggest that meloxicam enhances the mobilization of hematopoietic CD34+ blood cells in MM patients.Bone Marrow Transplantation advance online publication, 23 October 2017; doi:10.1038/bmt.2017.234.

AIMS OF THE STUDY Iron deficiency (ID) and iron deficiency anaemia (IDA) are important conditions affecting a large proportion of the general population, causing the patients physical and psychosomatic symptoms, particularly fatigue, and significantly affecting their quality of life. General practitioners (GPs) are frequently consulted with nonspecific symptoms due to the ID. However, little evidence is available to guide iron treatment. The aim of the Swiss Delphi study was to generate a broad consensual Swiss expert opinion in various therapeutic areas on diagnosis and treatment of ID/IDA and their practical implications. METHODS Specific statements regarding clinical relevance, practical diagnostic and therapeutic approaches, and treatment were evaluated by Swiss experts in various therapeutic areas using the Delphi method. “Consensus” was defined as ≥80% agreement; the agreement of 50–79% was defined as “critical”, of

Autologous stem cell transplantation (ASCT) continues to be a critical part of the disease control in younger patients with multiple myeloma (MM). Current evidence suggests that an induction treatm...

INTRODUCTION High-dose chemotherapy (HDCT)/autologous stem cell transplantation (ASCT) is the standard for patients with relapsed/refractory lymphomas and multiple myeloma (MM), thereby improving DFS and OS. Relapse after HDCT/ASCT remains the major cause of death in patients with lymphomas or MM after melphalan-based HDCT. Dose-intensified bendamustine by replacing carmustine in the BEAM regimen (BeEAM) or by combining it with melphalan (BenMel) is a promising strategy to lower the relapse rates.Renal toxicity after BeEAM emerges as a major concern. METHODS We investigated renal toxicity in consecutive lymphoma patients treated with BeEAM and in consecutive MM patients treated with the same dose of 400 mg/m2 bendamustine (split into 200 mg/m2 on two consecutive days) together with full-dosed (200 mg/m2) melphalan. Patients with a history of renal impairment before HDCT were included. We assessed renal damage summarized as acute kidney injury (AKI) by measuring renal parameters on a daily basis starting from the first day of HDCT until the last day of hospitalization for HDCT/ASCT. AKI: rise of s-creatinine ≥26.5 μmol/L in 48 hours or increase to more than or equal to twofold compared to baseline s-creatinine within 7 days (Kidney Disease International Global Organization, KDIGO, criteria). Grading of AKI: KDIGO. Treatment-related AKI (rAKI): occurred within 10 days from the last administration of bendamustine; no relation to sepsis. Consequently, we defined as treatment-unrelated AKI (uAKI) all renal damage occurring because of sepsis or later than 10 days since the last administration of bendamustine. Statistical Analysis Subgroup differences: Chi-squared test, Fisher Exact test. IBM SPSS software version 21. RESULTS Patient characteristics and therapy regimen: 122 consecutive patients with lymphomas or MM who underwent high- dose bendamustine regimen before ASCT in 01/2013-06/2016. Factors related to rAKIOccurrence of rAKI: correlated (p60 years, previous AKI, cardiovascular comorbidities and concomitant nephrotoxic drugs. In addition, rAKI correlated (p=0.004) with cardiovascular complications during hospitalization; details of subgroups analysis: Table 2.No differences in the incidence of rAKI MM (n=7/15; 46.7%) and lymphoma patients (n=44/107; 41.1%), p=0.683. Acute kidney Injury related to High Dose Bendamustine is reversible and manageable • Acute kidney injury related to bendamustine (rAKI): in 51 patients (41.8%); completely reversible in n=50/51 (98.0%). • rAKI: mild to moderate in 90% of affected patients; did not increase TRM after ASCT. • 3/51 patients (5.9%) with rAKI required transient renal dialysis to enable recovery from renal damage, whereas approaches such as additional hydration were sufficient in the vast majority (n=48 with rAKI; 94.1% of this subgroup). • The median duration of rAKI was 7 days (range, 1-22). ­ According to Cox ZL et al., Adverse Drug Events during AKI and its recovery, Clin J Am Soc Nephrol 2013; 8:1070-1078. CONCLUSION • Our data suggest that treatment-related acute renal toxicity is common in lymphoma and MM patients receiving dose-intensified bendamustine HDCT before ASCT. • However, renal impairment is reversible and manageable. • Our data identify a subgroup of patients at increased risk for the development of renal damage following bendamustine-based HDCT. • Such patients should be strictly monitored during hospitalization, and a generous hydration strategy before, during and after administration of bendamustine is recommended. • Assessing the pre-transplant renal risk profile may help to identify those patients, which may not be candidates for bendamustine-based HDCT thereby avoiding prolonged hospitalization due to rAKI and eventual transient dialysis treatment. • Our results may contribute to design appropriate selection criteria for dose-intensified bendamustine as part of the conditioning regimens preceding HDCT/ASCT in lymphoma and MM patients.

9016 Background: For patients (pts) with resectable stage IIIA(N2) non-small cell lung cancer (NSCLC) neoadjuvant chemotherapy (chemo) with 3 cycles cisplatin (cis)/docetaxel (doc) followed by surgery is an accepted standard of care leading to a 1-year (yr) event-free survival (EFS) of 48% and a 5-yr overall survival (OS) of 37%. PD-1/PD-L1 inhibitors have recently shown to lead to high response rates in resectable NSCLC. Methods: SAKK 16/14 is an open-label single-arm phase II study including 68 pts with resectable NSCLC stage IIIA(N2) (T1-3 N2 M0), irrespective of histological subtype, genomic aberrations or PD-L1 expression status. Neoadjuvant treatment consisted of 3 cycles of cis 100 mg/m2 and doc 85 mg/m2 q3w followed by 2 cycles of durvalumab 750 mg q2w. Durvalumab was continued after surgery q2w for 1 yr. The primary endpoint is EFS at 1 yr. The statistical hypothesis is to improve EFS at 1 yr from 48% based on the SAKK 16/00 study to 65%. Here, we report the primary endpoint and response data from 67 evaluable pts included in the study. Results: 68 pts were included from 06/16 to 01/19 and 67 pts (35 males, 32 females) were evaluable. Median age was 61 yrs (range, 41-74). 52 pts (77.6%) had a WHO PS of 0. 95.5% were current or former smokers. The majority of tumors were adenocarcinoma (55.2%) followed by squamous cell histology (32.8%). Clinical stage T1, T2 and T3 were present at diagnosis in 22.4%, 49.3% and 28.4%, respectively. 81.1% of pts underwent resection. The main reason for not undergoing surgery was disease progression (33.3%). Pneumonectomy was performed in 5 pts (9.1%), 43 pts underwent lobectomy and 7 pts bilobectomy. 30-day postoperative mortality was observed in one patient (1.8%). One patient died due to a bleeding complication after surgery most likely not related to neoadjuvant therapy. Radiographic response was 44.8% (95%CI: 32.6-57.4) after neoadjuvant chemo and 59.7% (95%CI: 46.4-71.9) after additional neoadjuvant immunotherapy. 1-yr EFS was 73.3% (90%CI: 62.5-81.4). Results for pathologic remission rate as well as correlation with PD-L1 status will be presented during the meeting. Conclusions: We report on treatment outcomes of the largest cohort of pts with resectable stage IIIA(N2) NSCLC receiving perioperative immune checkpoint inhibitor therapy. The addition of perioperative durvalumab to standard of care cis/doc is safe and leads to a high response rate and a very encouraging 1-yr EFS rate that appears substantially higher than with chemo alone. Clinical trial information: NCT 02572843.

BEAM with BCNU is commonly used for conditioning treatment followed by autologous stem cell transplantation (ASCT). However, pulmonary toxicity and availability issues associated with BCNU prompted us to evaluate bendamustine-replacing BCNU (BeEAM). We analyzed 39 lymphoma patients receiving BeEAM conditioning with 200 mg/m(2) bendamustine at days -7 and -6. The median duration until neutrophil recovery was 11 days, and 15 days for platelet recovery (>20 g/L). The most common grade 3/4 non-hematologic toxicities comprised mucosal side effects (27 pts.). Pulmonary toxicity was observed in one patient (2.5%), and one patient died of septic complications. The CR rate increased from 33% to 74% 100 days after ASCT. After a median follow-up of 18.5 months, progression and death each occurred in 11 patients (28%). Median progression-free and overall survival at 2 years were 69% and 72%. Our data suggest that BeEAM conditioning using bendamustine is safe and results in promising survival rates.

Background The aim was to evaluate quality of life (QoL), pain, and fatigue in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with different regimens after first-line docetaxel, as well as disease progression. Patients and Methods Patients with mCRPC having received first-line chemotherapy with docetaxel were eligible. Second-line treatment choice was at the discretion of the local investigator. All patients had regular assessments of QoL with the Functional Assessment of Cancer Therapy-Prostate (FACT-P) questionnaire, of fatigue with the Brief Fatigue Inventory, and of pain with the McGill Pain Questionnaire-Short Form. The primary end point was QoL maintenance defined as having a maximum decrease in 2 functional domains of the FACT-P. Results One hundred thirty-eight patients were included in 36 oncology centers across Switzerland. QoL analysis was available for all patients (59 who received cabazitaxel; 79 who received other therapy [OT] including 75 who received abiraterone). No significant differences for any of the end points were found between groups. A numerically higher number of patients had QoL maintenance with OT (25 of 79 patients, 32%) compared with cabazitaxel (8 of 59 patients, 14%). QoL improvement was found in 20% of patients (12 of 59) who received cabazitaxel and 24% (19 of 79) who received OT. Mean FACT-P score did not change in a clinically relevant manner over time in either group. Pain was present in 70% of patients (96 of 138), and a pain response to treatment was noted in 22% (13 of 59) who received cabazitaxel and 29% (23 of 79) who received OT. A similar but minor improvement of fatigue was noted in both groups. Conclusion Some degree of QoL decrease was seen in most patients regardless of second-line treatment. No significant differences in QoL parameters between cabazitaxel or other second line treatments were found.

Background Pemetrexed and bevacizumab as single agents have been approved for maintenance therapy after platinum-based induction in patients with advanced nonsquamous non–small-cell lung cancer. It is currently unknown whether bevacizumab plus pemetrexed is superior to pemetrexed alone. Patients and Methods We conducted a nonrandomized phase II trial with 2 sequential cohorts. In the first cohort, 77 patients were treated with 4 cycles of cisplatin, bevacizumab, and pemetrexed every 3 weeks, followed by bevacizumab plus pemetrexed maintenance until progression. In the second cohort, we treated 52 patients without bevacizumab, using maintenance with pemetrexed alone. Progression-free survival (PFS), overall survival (OS), overall response rate (ORR), adverse events, and the treatment costs of the 2 cohorts were compared. Results The median PFS from the time of registration was 6.9 months in cohort 1 and 5.6 months in cohort 2. The ORR was 62.3% in cohort 1% and 44.2% in cohort 2. The PFS (hazard ratio, 0.7; 95% confidence interval [CI], 0.5-1.0; P = .041) and ORR (odds ratio, 2.1; 95% CI, 1.0-4.3; P = .049) were better in cohort 1 than in cohort 2. No OS difference was found (hazard ratio, 1.0; 95% CI, 0.7-1.6; P = .890) after a median follow-up period of 47 months for cohort 1 and 27 months for cohort 2. The rate of grade ≥ 3 adverse events was greater in cohort 1. The treatment costs per patient were on average 1.4 times greater for cohort 1. Conclusion The addition of bevacizumab increased the ORR and PFS, but not OS, in our nonrandomized trial. Furthermore, the addition of bevacizumab was associated with greater toxicity and higher costs.

Objectives Molecular subclassification of non small-cell lung cancer (NSCLC) is essential to improve clinical outcome. This study assessed the prognostic and predictive value of circulating micro-RNA (miRNA) in patients with non-squamous NSCLC enrolled in the phase II SAKK (Swiss Group for Clinical Cancer Research) trial 19/05, receiving uniform treatment with first-line bevacizumab and erlotinib followed by platinum-based chemotherapy at progression. Materials and methods Fifty patients with baseline and 24h blood samples were included from SAKK 19/05. The primary study endpoint was to identify prognostic (overall survival, OS) miRNA's. Patient samples were analyzed with Agilent human miRNA 8x60K microarrays, each glass slide formatted with eight high-definition 60K arrays. Each array contained 40 probes targeting each of the 1347 miRNA. Data preprocessing included quantile normalization using robust multi-array average (RMA) algorithm. Prognostic and predictive miRNA expression profiles were identified by Spearman's rank correlation test (percentage tumor shrinkage) or log-rank testing (for time-to-event endpoints). Results Data preprocessing kept 49 patients and 424 miRNA for further analysis. Ten miRNA's were significantly associated with OS, with hsa-miR-29a being the strongest prognostic marker (HR=6.44, 95%-CI 2.39–17.33). Patients with high has-miR-29a expression had a significantly lower survival at 10 months compared to patients with a low expression (54% versus 83%). Six out of the 10 miRNA's (hsa-miRN-29a, hsa-miR-542-5p, hsa-miR-502-3p, hsa-miR-376a, hsa-miR-500a, hsa-miR-424) were insensitive to perturbations according to jackknife cross-validation on their HR for OS. The respective principal component analysis (PCA) defined a meta-miRNA signature including the same 6 miRNA's, resulting in a HR of 0.66 (95%-CI 0.53–0.82). Conclusion Cell-free circulating miRNA-profiling successfully identified a highly prognostic 6-gene signature in patients with advanced non-squamous NSCLC. Circulating miRNA profiling should further be validated in external cohorts for the selection and monitoring of systemic treatment in patients with advanced NSCLC.

Insertion of central venous port (CVP) catheter in the cancer population is associated with increased incidence of venous thromboembolic events (VTE). However, trials have shown limited benefit of antithrombotic treatment to prevent catheter-related venous thrombosis. This prospective observational cohort study was designed to assess the incidence of VTE closely related to CVP implantation in patients with cancer and undergoing chemotherapy, and to identify a high risk subgroup of patients. Between February 2006 and December 2011, 1097 consecutive cancer patients with first CVP implantation were included. Catheter-related VTE were defined as deep venous thrombosis in the arm, with or without pulmonary embolism (PE), or isolated PE. The incidence of CVP-associated VTE was 5.9% (IC95 4.4–7.3%) at 3 months, and 11.3% (IC95 9.4–13.2%) at 12 months. The incidence of any VTE was 7.6% (IC95 6.0–9.3%) at 3 months, and 15.3% (IC95 13.1–17.6%) at 12 months. High Khorana risk score and lung cancer were significant predictors of 3 month VTE. In conclusion, this large cohort study of patients with first CVP catheter implantation confirms the high incidence of VTE associated with the CVP implantation and allow identifying high risk patients who may benefit from thromboprophylaxis.

Background Low intensity, intermediate frequency, alternating electric fields (Tumor Treating Fields; TTFields) exhibit anti-mitotic activity in cancer cells. Promising preclinical data have led to a single arm phase I/II trial in NSCLC patients. Methods Forty-two inoperable stage IIIB (with pleural effusion) and IV NSCLC patients who had had tumor progression received pemetrexed 500 mg/m2 iv q3w together with daily TTFields therapy until disease progression. The primary endpoint was time to “in-field” progression. Results Median age for all patients was 63 years, 76% had stage IV disease, 78% had adenocarcinoma and 17% had performance status of 2. The median time to in-field progression was 28 weeks and the median time to systemic progression was 22 weeks. Six patients (14.6%) had a partial remission (PR) and 20 had stable disease (SD) (48.8%). Median overall survival was 13.8 months and 1 year survival rate was 57%. There were no TTFields-related serious adverse events. Conclusions The combination of TTFields and pemetrexed as a second line therapy for NSCLC is safe and potentially more effective than pemetrexed alone. TTFields improved disease control within the treatment field and a phase III study is planned to further investigate its role as a novel treatment in NSCLC.

Chemotherapy-induced alopecia is very distressing for a patient and may have an impact on treatment decisions. On docetaxel-based therapy, alopecia occurs in a substantial proportion of patients. We aimed to investigate whether two different methods of scalp cooling can prevent hair loss.In this open-label, prospective, nonrandomized trial, patients with solid tumors receiving docetaxel in a palliative setting were allocated according to patients' preference to short-term cooling (over 45 min postinfusion) with a Paxman PSC-2 machine (PAX), with cold cap (CC), or no cooling. The combined endpoint was alopecia World Health Organisation (WHO) III or IV or the necessity to wear a wig. Study identifier is Clinicaltrials.gov NCT01008774.Two hundred thirty-eight patients were included in the trial (128 patients PAX, 71 CC, and 39 no cooling). Number of cycles (median 4) and median docetaxel doses were similar across groups (55-60 mg/day on weekly therapy, 135-140 mg/day on 3-weekly therapy). Alopecia occurred with PAX, CC, and no cooling under 3-weekly docetaxel in 23, 27, and 74% and under weekly docetaxel in 7, 8, and 17%, respectively. Overall, cooling (PAX and CC combined) reduced risk of alopecia by 78% (hazard ratio 0.22; 95% confidence interval 0.12 to 0.41). CC and PAX prophylaxis led to the same degree of prevention of alopecia. Adverse events (AE) were reported in 5% (most frequently, sensation of cold), and 30 patients (13%) discontinued cooling measures after cycle 1.In this first comparison published to date, both PAX and CC offer efficacious protection against hair loss, in particular when docetaxel is administered in a 3-weekly interval.

Purpose This phase II trial aimed to evaluate feasibility and efficacy of a first-line combination of targeted therapies for advanced non-squamous NSCLC: bevacizumab (B) and erlotinib (E), followed by platinum-based CT at disease progression (PD). Methods 103 patients with advanced non-squamous NSCLC were treated with B (15 mg/kg day 1 of each 21-day cycle) and E (150 mg daily) until PD or unacceptable toxicity. Upon PD patients received 6 cycles of CT (cisplatin/carboplatin and gemcitabine). The primary endpoint was disease stabilization rate (DSR) after 12 weeks of BE treatment. Results 101 patients were evaluable. Under BE, DSR at week 12 was 54.5%. 73 patients had at least stable disease (SD), including 1 complete remission and 17 partial responses (PR). No unexpected toxicities were observed. Median time to progression (TTP) under BE was 4.1 months. 62 patients started CT; 35 received at least 4 cycles (6 PR, 32 SD). At a median follow-up of 36 months, median overall survival (OS) was 14.1 months. Conclusions First-line BE treatment followed by a fixed CT regimen at PD is feasible with acceptable toxicity and activity. In a non-squamous NSCLC population unselected for EGFR status, we found OS rates similar to standard CT.

BACKGROUND: Stage IIIB non-small-cell lung cancer (NSCLC) is usually thought to be unresectable, and is managed with chemotherapy with or without radiotherapy. However, selected patients might benefit from surgical resection after neoadjuvant chemotherapy and radiotherapy. The aim of this multicentre, phase II trial was to assess the efficacy and toxicity of a neoadjuvant chemotherapy and radiotherapy followed by surgery in patients with technically operable stage IIIB NSCLC. METHODS: Between September, 2001, and May, 2006, patients with pathologically proven and technically resectable stage IIIB NSCLC were sequentially treated with three cycles of neoadjuvant chemotherapy (cisplatin with docetaxel), immediately followed by accelerated concomitant boost radiotherapy (44 Gy in 22 fractions) and definitive surgery. The primary endpoint was event-free survival at 12 months. Efficacy analyses were done by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00030810. FINDINGS: 46 patients were enrolled, with a median age of 60 years (range 28-70). 13 (28%) patients had N3 disease, 36 (78%) had T4 disease. All patients received chemotherapy; 35 (76%) patients received radiotherapy. The main toxicities during chemotherapy were neutropenia (25 patients [54%] at grade 3 or 4) and febrile neutropenia (nine [20%]); the main toxicity after radiotherapy was oesophagitis (ten patients [29%]; nine grade 2, one grade 3). 35 patients (76%) underwent surgery, with pneumonectomy in 17 patients. A complete (R0) resection was achieved in 27 patients. Peri-operative complications occurred in 14 patients, including two deaths (30-day mortality 5.7%). Seven patients required a second surgical intervention. Pathological mediastinal downstaging was seen in 11 of the 28 patients who had lymph-node involvement at enrolment, a complete pathological response was seen in six patients. Event-free survival at 12 months was 54% (95% CI 39-67). After a median follow-up of 58 months, the median overall survival was 29 months (95% CI 16.1-NA), with survival at 1, 3, and 5 years of 67% (95% CI 52-79), 47% (32-61), and 40% (24-55). INTERPRETATION: A treatment strategy of neoadjuvant chemotherapy and radiotherapy followed by surgery is feasible in selected patients. Toxicity is considerable, but manageable. Survival compares favourably with historical results of combined treatment for less advanced stage IIIA disease.

Summary Background In patients with malignant pleural mesothelioma undergoing a multimodality therapy, treatment toxicity may outweigh the benefit of progression-free survival. The subjective experience across different treatment phases is an important clinical outcome. This study compares a standard with an individual quality of life (QoL) measure used in a multi-center phase II trial. Patients and methods Sixty-one patients with stage I–III technically operable pleural mesothelioma were treated with preoperative chemotherapy, followed by pleuropneumonectomy and subsequent radiotherapy. QoL was assessed at baseline, at day 1 of cycle 3, and 1, 3 and 6 months post-surgery by using the Rotterdam Symptom Checklist (RSCL) and the Schedule for the Evaluation of Quality of Life-Direct Weighting (SEIQoL-DW), a measure that is based on five individually nominated and weighted QoL-domains. Results Completion rates were 98% (RSCL) and 92% (SEIQoL) at baseline and 98%/89% at cycle 3, respectively. Of the operated patients (N = 45) RSCL and SEIQoL were available from 86%/72%, 93%/74%, and 94%/76% at months 1, 3, and 6 post-surgery. Average assessment time for the SEIQoL was 24 min compared to 8 min needed for the RSCL. Median changes from baseline indicate that both RSCL QoL overall score and SEIQoL index remained stable during chemotherapy with a clinically significant deterioration (change ≥ 8 points) 1 month after surgery (median change of −66 and −14 for RSCL and SEIQoL, respectively). RSCL QoL overall scores improved thereafter, but remained beneath baseline level until 6 months after surgery. SEIQoL scores improved to baseline-level at month 3 after surgery, but worsened again at month 6. RSCL QoL overall score and SEIQoL index were moderately correlated at baseline (r = .30; p ≤ .05) and at 6-month follow-up (r = .42; p ≤ .05) but not at the other time points. Conclusion The SEIQoL assessment seems to be feasible within a phase II clinical trial, but may require more effort from staff. More distinctive QoL changes in accordance with clinical changes were measured with the RSCL. Our findings suggest that the two measures are not interchangeable: the RSCL is to favor when mainly information related to the course of disease- and treatment is of interest.

Background: The role of epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKI) in the treatment of patients with advanced non-small cell lung cancer (NSCLC) and unknown EGFR mutation status has recently been questioned. Patients and Methods: We conducted a retrospective study of patients with unknown EGFR mutation status and long-term response (LTR) to gefitinib in the Swiss Iressa expanded access program (EAP). We assessed patient characteristics, and performed Sanger sequencing and next generation sequencing on archived tumor tissue. We hypothesized that EGFR mutations are prevalent in patients with LTR. Results: Of 430 patients in the EAP, 18 (4%) fulfilled our definition of LTR, and 16 of them had archived tumor tissue. Patient characteristics were as expected for age, sex, and smoking history. Median duration of therapy was 38 months (range 24-142 months). Sanger sequencing revealed EGFR exon 18-21 mutations in 6 (38%) of the tumors. Next generation sequencing revealed no further EGFR-mutated cases, but reported in 15 (94%) of the tumors mutations in other genes (ALK, BRAF, DDR2, KEAP1, MET, PTEN, STK11) previously associated with NSCLC. Conclusion: Larger studies are needed to define the prognostic values of different driver mutations in patients with NSCLC.

Vinorelbine chemotherapy with granulocyte-colony stimulating factor (G-CSF) stimulation is a widely applied non-myelosuppressive mobilization regimen in Switzerland for myeloma patients, but its neurotoxic potential limits its use in patients with bortezomib-induced polyneuropathy. In this single-center study, we alternatively evaluated safety and effectiveness of gemcitabine chemotherapy with G-CSF for mobilization of autologous stem cells. Between March 2012 and February 2013, all bortezomib-pretreated myeloma patients planned to undergo first-line high-dose melphalan chemotherapy received a single dose of 1250 mg/m(2) gemcitabine, with G-CSF started on day 4. The 24 patients in this study had received a median of four cycles of bortezomib-dexamethason-based induction. Bortezomib-related polyneuropathy was identified in 21 patients (88%) by clinical evaluation and a standardized questionnaire. Administration of gemcitabine mobilization did not induce new or aggravate pre-existing neuropathy. Stem cell mobilization was successful in all 24 patients, with a single day of apheresis being sufficient in 19 patients (78%). The median yield was 9.51 × 10(6) CD34+ cells/kg. Stem collection could be accomplished at day 8 in 67%. Our data suggest that single-dose gemcitabine together with G-CSF is an effective mobilization regimen in myeloma patients and a safe alternative non-myelosuppressive mobilization chemotherapy for myeloma patients with bortezomib-induced polyneuropathy.

The availability of drugs such as thalidomide, bortezomib and lenalidomide changed the landscape in myeloma treatment and has extended the median survival up to 10 years with a substantial improvement in quality of life. This development prompted a Swiss expert panel to re-evaluate the current status and formulate updated clinical recommendations for the diagnosis and treatment of plasma cell myeloma. These recommendations should help clinicians in their decision making to achieve the best outcome based on currently available data.

Summary Background One of the standard options in the treatment of stage IIIA/N2 non-small-cell lung cancer is neoadjuvant chemotherapy and surgery. We did a randomised trial to investigate whether the addition of neoadjuvant radiotherapy improves outcomes. Methods We enrolled patients in 23 centres in Switzerland, Germany and Serbia. Eligible patients had pathologically proven, stage IIIA/N2 non-small-cell lung cancer and were randomly assigned to treatment groups in a 1:1 ratio. Those in the chemoradiotherapy group received three cycles of neoadjuvant chemotherapy (100 mg/m 2 cisplatin and 85 mg/m 2 docetaxel) followed by radiotherapy with 44 Gy in 22 fractions over 3 weeks, and those in the control group received neoadjuvant chemotherapy alone. All patients were scheduled to undergo surgery. Randomisation was stratified by centre, mediastinal bulk (less than 5 cm vs 5 cm or more), and weight loss (5% or more vs less than 5% in the previous 6 months). The primary endpoint was event-free survival. Analyses were done by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00030771. Findings From 2001 to 2012, 232 patients were enrolled, of whom 117 were allocated to the chemoradiotherapy group and 115 to the chemotherapy group. Median event-free survival was similar in the two groups at 12·8 months (95% CI 9·7–22·9) in the chemoradiotherapy group and 11·6 months (8·4–15·2) in the chemotherapy group (p=0·67). Median overall survival was 37·1 months (95% CI 22·6–50·0) with radiotherapy, compared with 26·2 months (19·9–52·1) in the control group. Chemotherapy-related toxic effects were reported in most patients, but 91% of patients completed three cycles of chemotherapy. Radiotherapy-induced grade 3 dysphagia was seen in seven (7%) patients. Three patients died in the control group within 30 days after surgery. Interpretation Radiotherapy did not add any benefit to induction chemotherapy followed by surgery. We suggest that one definitive local treatment modality combined with neoadjuvant chemotherapy is adequate to treat resectable stage IIIA/N2 non-small-cell lung cancer.

The role of adjuvant chemotherapy in patients with early-stage non-small cell lung cancer (NSCLC) remained controversial for many years. Although a positive impact on overall survival was long suggested for cisplatin-based chemotherapy, early randomized clinical trials failed to confirm a clear survival benefit. Recently, the results from 4 large randomized trials, IALT, JBR.10, CALGB 9633, and ANITA indicate a significant survival benefit with adjuvant chemotherapy for patients with IB through IIIA NSCLC, and the results of these trials support the adoption of chemotherapy in addition to surgery as a new standard of care. Neoadjuvant chemotherapy is potentially better tolerated compared to post-surgical adjuvant chemotherapy, though definitive survival benefits with this approach have yet to be shown. The current status of adjuvant and neoadjuvant chemotherapy for patients with early-stage NSCLC will be discussed.

Mediastinal lymph-node dissection was compared to systematic mediastinal lymph-node sampling in patients undergoing complete resection for non-small cell lung cancer with respect to morbidity, duration of chest tube drainage and hospitalization, survival, disease-free survival, and site of recurrence.A consecutive series of one hundred patients with non-small-cell lung cancer, clinical stage T1-3 N0-1 after standardized staging, was divided into two groups of 50 patients each, according to the technique of intraoperative mediastinal lymph-node assessment (dissection versus sampling). Mediastinal lymph-node dissection consisted of removal of all lymphatic tissues within defined anatomic landmarks of stations 2-4 and 7-9 on the right side, and stations 4-9 on the left side according to the classification of the American Thoracic Society. Systematic mediastinal lymph-node sampling consisted of harvesting of one or more representative lymph nodes from stations 2-4 and 7-9 on the right side, and stations 4-9 on the left side.All patients had complete resection. A mean follow-up time of 89 months was achieved in 92 patients. The two groups of patients were comparable with respect to age, gender, performance status, tumor stage, histology, extent of lung resection, and follow-up time. No significant difference was found between both groups regarding the duration of chest tube drainage, hospitalization, and morbidity. However, dissection required a longer operation time than sampling (179 +/- 38 min versus 149 +/- 37 min, p0.001). There was no significant difference in overall survival between the two groups; however, patients with stage I disease had a significantly longer disease-free survival after dissection than after sampling (60.2 +/- 7 versus 44.8 +/- 8 months, p0.03). Local recurrence was significantly higher after sampling than after dissection in patients with stage I tumor (12.5% versus 45%, p = 0.02) and in patients with nodal tumor negative mediastinum (N0/N1 disease) (46% versus 13%, p = 0.004).Our results suggest that mediastinal lymph-node dissection may provide a longer disease-free survival in stage I non-small cell lung cancer and, most importantly, a better local tumor control than mediastinal lymph-node sampling after complete resection for N0/N1 disease without leading to increased morbidity.

Purpose To evaluate the effect of single-agent rituximab given at the standard or a prolonged schedule in patients with newly diagnosed, or refractory or relapsed mantle cell lymphoma (MCL). Patients and Methods After induction treatment with the standard schedule (375 mg/m2 weekly × 4), patients who were responding or who had stable disease at week 12 from the start of treatment were randomly assigned to no further treatment (arm A) or prolonged rituximab administration (375 mg/m2) every 8 weeks for four times (arm B). Results The trial enrolled 104 patients. After induction, clinical response was 27% with 2% complete responses. Among patients with detectable t(11;14)-positive cells in blood and bone marrow at baseline, four of 20, and one of 14, respectively, became polymerase chain-reaction–negative after induction. Anemia was the only adverse predictor of response in the multivariate analysis. After a median follow-up of 29 months, response rate and duration of response were not significantly different between the two schedules in 61 randomly assigned patients. Median event-free survival (EFS) was 6 months in arm A versus 12 months in arm B; the difference was not significant (P = .1). Prolonged treatment seemed to improve EFS in the subgroup of pretreated patients (5 months in arm A v 11 months in arm B; P = .04). Thirteen percent of patients in arm A and 9% in arm B presented with grade 3 to 4 hematologic toxicity. Conclusion Single-agent rituximab is active in MCL, but the addition of four single doses at 8-week intervals does not seem to significantly improve response rate, duration of response, or EFS after treatment with the standard schedule.

Purpose: A multicenter, phase II trial investigated the efficacy and toxicity of neoadjuvant docetaxel-cisplatin in locally advanced non–small-cell lung cancer (NSCLC) and examined prognostic factors for patients not benefiting from surgery. Patients and Methods: Ninety patients with previously untreated, potentially operable stage IIIA (mediastinoscopically pN2) NSCLC received three cycles of docetaxel 85 mg/m2 day 1 plus cisplatin 40 mg/m2 days 1 and 2, with subsequent surgical resection. Results: Administered dose-intensities were docetaxel 85 mg/m2/3 weeks (range, 53 to 96) and cisplatin 95 mg/m2/3 weeks (range, 0 to 104). The 265 cycles were well tolerated, and the overall response rate was 66% (95% confidence interval [CI], 55% to 75%). Seventy-five patients underwent tumor resection with positive resection margin and involvement of the uppermost mediastinal lymph node in 16% and 35% of patients, respectively (perioperative mortality, 3%; morbidity, 17%). Pathologic complete response occurred in 19% of patients with tumor resection. In patients with tumor resection, downstaging to N0–1 at surgery was prognostic and significantly prolonged event-free survival (EFS) and overall survival (OS; P = .0001). At median follow-up of 32 months, the median EFS and OS were 14.8 months (range, 2.4 to 53.4) and 33 months (range, 2.4 to 53.4), respectively. Local relapse occurred in 27% of patients with tumor resection, with distant metastases in 37%. Multivariate analyses identified mediastinal clearance (hazard ratio, 0.22; P = .0003) and complete resection (hazard ratio, 0.26; P = .0006) as strongly prognostic for increased survival. Conclusion: Neoadjuvant docetaxel-cisplatin is effective and tolerable in stage IIIA pN2 NSCLC. Resection is recommended only for patients with mediastinal downstaging after chemotherapy.

Background Prospective assessment of accuracy and safety of video-mediastinoscopy (VMS) in patients without pretreatment and those after induction therapy for potentially operable non–small cell lung cancer. Methods Between 1996 and 1999, 219 patients underwent VMS at our institution: 195 patients without pretreatment and 24 after completion of induction therapy. Mediastinal lymph nodes were dissected and biopsied according to the American Thoracic Society (ATS) lymph node mapping system using a video-assisted approach. The accuracy of VMS was assessed for each patient according to the results obtained from mediastinal lymph node dissection (MLND) performed during lung resection. Results Video-mediastinoscopy in patients without pretreatment revealed a sensitivity, specificity, and accuracy as compared with MLND of 87%, 100%, and 95.6%, respectively, and a procedure-related complication rate of 4% (8/195 patients). Video-mediastinoscopy in patients after induction therapy revealed a sensitivity, specificity, and accuracy of 81%, 100%, and 91% as compared with MLND, without apparent complications. Conclusions Video-mediastinoscopy performed after induction therapy for non–small cell lung cancer is as accurate as mediastinoscopy in patients without pretreatment and did not confer additional morbidity.

Purpose: We aimed to identify gene expression signatures associated with angiogenesis and hypoxia pathways with predictive value for treatment response to bevacizumab/erlotinib (BE) of nonsquamous advanced non–small cell lung cancer (NSCLC) patients. Experimental Design: Whole-genome gene expression profiling was performed on 42 biopsy samples (from SAKK 19/05 trial) using Affymetrix exon arrays, and associations with the following endpoints: time-to-progression (TTP) under therapy, tumor-shrinkage (TS), and overall survival (OS) were investigated. Next, we performed gene set enrichment analyses using genes associated with the angiogenic process and hypoxia response to evaluate their predictive value for patients' outcome. Results: Our analysis revealed that both the angiogenic and hypoxia response signatures were enriched within the genes predictive of BE response, TS, and OS. Higher gene expression levels (GEL) of the 10-gene angiogenesis-associated signature and lower levels of the 10-gene hypoxia response signature predicted improved TTP under BE, 7.1 months versus 2.1 months for low versus high-risk patients (P = 0.005), and median TTP 6.9 months versus 2.9 months (P = 0.016), respectively. The hypoxia response signature associated with higher TS at 12 weeks and improved OS (17.8 months vs. 9.9 months for low vs. high-risk patients, P = 0.001). Conclusions: We were able to identify gene expression signatures derived from the angiogenesis and hypoxia response pathways with predictive value for clinical outcome in advanced nonsquamous NSCLC patients. This could lead to the identification of clinically relevant biomarkers, which will allow for selecting the subset of patients who benefit from the treatment and predict drug response.

Treatment allocation by epidermal growth factor receptor mutation status is a new standard in patients with metastatic nonesmall-cell lung cancer. Yet, relatively few modern chemotherapy trials were conducted in patients characterized by epidermal growth factor receptor wild type. We describe the results of a multicenter phase II trial, testing in parallel 2 novel combination therapies, predefined molecular markers, and tumor rebiopsy at progression. Objective: The goal was to demonstrate that tailored therapy, according to tumor histology and epidermal growth factor receptor (EGFR) mutation status, and the introduction of novel drug combinations in the treatment of advanced nonesmall-cell lung cancer are promising for further investigation. Methods: We conducted a multicenter phase II trial with mandatory EGFR testing and 2 strata. Patients with EGFR wild type received 4 cycles of bevacizumab, pemetrexed, and cisplatin, followed by maintenance with bevacizumab and pemetrexed until progression. Patients with EGFR mutations received bevacizumab and erlotinib until progression. Patients had computed tomography scans every 6 weeks and repeat biopsy at progression. The primary end point was progression-free survival (PFS) ≥ 35% at 6 months in stratum EGFR wild type; 77 patients were required to reach a power of 90% with an alpha of 5%. Secondary end points were median PFS, overall survival, best overall response rate (ORR), and tolerability. Further biomarkers and biopsy at progression were also evaluated. Results: A total of 77 evaluable patients with EGFR wild type received an average of 9 cycles (range, 1-25). PFS at 6 months was 45.5%, median PFS was 6.9 months, overall survival was 12.1 months, and ORR was 62%. Kirsten rat sarcoma oncogene mutations and circulating vascular endothelial growth factor negatively correlated with survival, but thymidylate synthase expression did not. A total of 20 patients with EGFR mutations received an average of 16.

The concept of resilience is gaining increasing importance as a key component of supportive care but to date has rarely been addressed in studies with adult cancer patients. The purpose of our study was to describe resilience and its potential predictors and supportive care needs in cancer patients during early treatment and to explore associations between both concepts.This descriptive study included adult cancer patients under treatment in ambulatory cancer services of a Swiss hospital. Subjects completed the 25-item Connor-Davidson-Resilience Scale and the 34-item Supportive Care Needs Survey. Descriptive, correlational and regression analysis were performed.68 patients with cancer were included in the study. Compared to general population, resilience scores were significantly lower (74.4 ± 12.6 vs. 80.4 ± 12.8, p = .0002). Multiple regression analysis showed predictors ("age", "metastasis", "recurrence" and "living alone") of resilience (adjusted R2 = .19, p .001). Highest unmet needs were observed in the domain of psychological needs. Lower resilience scores were significantly and strongly associated with higher levels of unmet psychological needs (Rho = -.68, p .001), supportive care needs (Rho = -.49, p .001) and information needs (Rho = -.42, p = .001).Ambulatory patients with higher levels of resilience express fewer unmet needs. Further work is needed to elucidate the mechanism of the observed relationships and if interventions facilitating resilience have a positive effect on unmet needs.

The occurrence of varicella zoster virus (VZV) reactivation is increased after allogeneic transplantation whereas limited data are available for herpes zoster (HZ) after autologous SCT (ASCT). We determined the incidence and the prognostic significance of HZ and its correlation with VZV serology in 191 consecutive myeloma patients undergoing high dose melphalan chemotherapy with ASCT. We found that VZV reactivation occurred in 57 (30) patients in 8.5 during induction and in 21.5 after ASCT peaking at 8 months after ASCT. Disease burden due to HZ was assessed as high or rather high in 70 of the patients. By immune fluorescence and Serion Elisa VZV IgG assessment 90.8 of all patients had specific anti VZV antibodies at ASCT. Lower specific antibody titers at transplantation were observed in patients with HZ after ASCT than in those without reactivation (P=0.009). Finally OS was better in myeloma patients with HZ after ASCT compared with patients without HZ (P=0.007). Our data indicate that VZV reactivation after ASCT is a frequent event carrying a significant disease burden and it is associated with improved survival. Low levels of specific VZV antibodies at ASCT suggest increased vulnerability for VZV reactivation.Bone Marrow Transplantation advance online publication 19 January 2015; doi:10.1038/bmt.2014.290.

Introduction The World Health Organization classification of chronic myeloproliferative disease encompasses eight entities of bone marrow neoplasms, among them Breakpoint cluster region-Abelson murine leukemia viral oncogene homolog 1-positive chronic myeloid leukemia and polycythemia vera. Polycythemia vera requires, in the majority of cases (95%), the negativity of Breakpoint cluster region-Abelson murine leukemia viral oncogene homolog 1 rearrangement and the presence of the Janus kinase 2 mutation. We report a case of erythrocytosis as the primary manifestation of a chronic myeloid leukemia, with the presence of the Philadelphia chromosome and the Breakpoint cluster region-Abelson murine leukemia viral oncogene homolog 1 fusion gene, and in the absence of any Janus kinase 2 mutation. Case presentation A 68-year-old Caucasian woman, with a history of cigarette consumption and obstructive sleep apnoea syndrome (undergoing continuous positive airway pressure treatment) had presented to our institution with fatigue and a hemoglobin level of 18.6g/L, with slight leukocytosis at 16G/L, and no other anomalies on her complete blood cell count. Examination of her arterial blood gases found only a slight hypoxemia; erythropoietin and ferritin levels were very low and could not explain a secondary erythrocytosis. Further analyses revealed the absence of any Janus kinase 2 mutation, thus excluding polycythemia vera. Taken together with a high vitamin B12 level, we conducted a Breakpoint cluster region-Abelson murine leukemia viral oncogene homolog 1 gene analysis and bone marrow cytogenetic analysis, both of which returned positive, leading to the diagnosis of chronic myeloid leukemia. Conclusions To date, this case is the first description of a Breakpoint cluster region-Abelson murine leukemia viral oncogene homolog 1-positive chronic myeloid leukemia, presenting with erythrocytosis as the initial manifestation, and mimicking a Janus kinase 2 V617F-negative polycythemia vera. Her impressive response to imatinib therapy underscores the importance of not missing this diagnosis.

Rituximab 375 mg/m(2) weekly x 4 has been reported to induce a 60% response rate in patients with relapsed follicular lymphomas (FL). Our aim was to examine the effect of this rituximab schedule on circulating FL cells in an ongoing multicenter study. One hundred fifty-four patients with FL were examined by nested polymerase chain reaction (PCR) at baseline for the presence of t(14;18) translocation-carrying lymphoma cells in bone marrow and/or blood. Sixty-four patients (42%) had PCR-detectable t(14;18)(+) FL cells. Pretreatment characteristics of these 64 patients were as follows: one had stage I, nine had stage II, 14 had stage III, and 40 had stage IV disease. Thirty-five patients had bulky disease (or = 5 cm) and 25 patients had an elevated serum lactate dehydrogenase (LDH) level. Bone marrow was morphologically assessed in 64 patients, and 39 of these patients had an infiltration with FL cells. Blood samples from 51 patients were available for PCR analysis between weeks 8-12 after induction therapy, and 28 of these patients (55%) were PCR negative. Paired blood and bone marrow samples were available for PCR analysis from 39 patients between weeks 8-12 after induction therapy with rituximab. Thirteen of these patients (33%) did not have PCR-detectable cells in blood and bone marrow, while 26 patients (67%) still had circulating t(14;18)(+) cells in either bone marrow (eight patients), blood (one patient), or both (17 patients). PCR negativity in blood and bone marrow in 13 patients was statistically significantly associated with partial or complete response after induction therapy with rituximab (P = 0.006). However, clearance of PCR-detectable t(14;18)(+) cells in bone marrow and/or blood could not be associated with any low tumor burden pretreatment characteristics such as stages I/II, absence of morphological bone marrow infiltration or tumor bulk ofor = 5 cm, and normal serum LDH.

Tumours develop through the accumulation of genetic alterations associated with a progressive increase of the malignant phenotype. In lung cancer, chronic exposure of bronchial epithelium to carcinogens in cigarette smoke may lead to multiple dysplastic and hyperplastic lesions scattered throughout the tracheobronchial tree. Little is known about the genetic alterations in such lesions. This study was carried out to examine cyclin D1 (CCND1) and retinoblastoma (RB1) gene expression in the bronchial epithelium of patients with lung cancer. Lung tumours and their corresponding tumour-free resection margins from 33 patients who underwent resection of non-small-cell lung cancer (NSCLC) were examined by immunostaining with monoclonal antibodies against cyclin D1 (DCS-6; Novocastra) and pRb (NCL Rb-1; Novocastra). Examination of the resection margins revealed four carcinomas in situ, 19 hyperplasias and ten sections showing apparently normal bronchial epithelium. A control group of patients, without lung tumours and who had never smoked, revealed no or weak cyclin D1 and positive pRb staining within bronchial epithelia. Increased cyclin D1 and diminished pRb expression were found in 76% (n = 25) and 27% (n = 9) of the resection margins respectively, and in 12% (n = 4) both cyclin D1 and pRb expression were altered. In the corresponding tumours, 48% (n = 16) were normal, while altered expression was found for cyclin D1 in 33% (n = 11), pRb in 27% (n = 9) and both in 9% (n = 3) of cases. It appears that altered expression of cyclin D1 and pRb is an early event in NSCLC development in almost half of cases analysed. Further investigations are needed to determine the significance of immunostaining of bronchial specimens in individuals at risk of lung cancer, with the possibility that the observations are of importance in the early diagnosis of NSCLC.

Amifostine (WR-2721), a thiol compound, has been shown to protect normal tissue from alkylating agents and cisplatin-induced toxicity without loss of anti-tumour effects. To confirm this result, we conducted a phase II randomised trial to determine if the addition of amifostine reduces the toxicity of carboplatin without loss of anti-tumour activity in patients with inoperable non-small-cell lung cancer (NSCLC). After the first course of carboplatin (600 mg m-2 i.v. infusion), 21 patients were randomised to receive three cycles of carboplatin alone (C arm) or three infusions of amifostine at 910 mg m-2 (CA arm) at 28 day intervals. The amifostine was given 20 min before and at 2 and 4 h after carboplatin. Since the 910 mg m-2 amifostine infusion led to hypotension in six patients, the dosage was reduced by 25%, to 683 mg m-2 t.i.d., in the other four patients. Amifostine was well tolerated at this dose level. Five patients in the CA arm and three in the C arm had their planned treatment discontinued owing to progressive disease (n = 3), amifostine side-effects (hypotension, sneezing and sickness, n = 4), and carboplatin-induced thrombocytopenia (n = 1). Bone marrow and renal function at study entry and after the first course of carboplatin before randomisation were similar in both treatment arms. Twenty courses of carboplatin+amifostine have been compared with 25 courses of carboplatin alone. Although there was no statistically significant difference with respect to haematological values comparing both arms, the median time to platelet recovery (> 100 x 10(9) l-1) (13.5 days vs 21 days; P = 0.04) and the need for hospitalisation for i.v. antibiotic and other supportive treatment tended to be reduced in the CA arm (0/20 vs 6/25 patient courses; P = 0.06). Response rates and median survival (14 vs 9 months) were no different, excluding tumour protection activity by amifostine. These results with a small number of patients suggest that amifostine given with carboplatin may reduce the duration of thrombocytopenia and hospitalisation.

Rationale: Proteasome inhibitor-refractory multiple myeloma (MM) patients are a difficult to treat population with a very poor prognosis. The activity of registered, current or next generation MM drugs (pomalidomide, carfilzomib, daratumumab) in heavily pretreated, proteasome inhibitor-refractory MM is in the range of 30%. The biology of proteasome inhibitor resistance is driven by adaptive downregulation of the unfolded protein response (UPR), which regulates plasma cell maturation and sensitivity to proteasome inhibitor treatment (Leung-HagesteijnC. et al., Cancer Cell 2013 Sep 9;24(3):289-304). The oral HIV protease inhibitor nelfinavir (NFV) has anti-MM activity in vivo, triggers UPR activation, sensitizes MM to proteasome inhibitors and overcomes proteasome inhibitor resistance in vitro. Combination therapy with NFV and bortezomib (BTZ) showed UPR activation in vivo and strong signals of activity in bortezomib-refractory MM in the SAKK 65/08 phase I trial (Driessen C. et al.,Haematologica 2016 Mar;101(3):346-55). Objective: We performed a prospective, multicenter phase II trial to assess the activity ofnelfinavir,bortezomiband dexamethasone (NVd) in proteasome inhibitor-refractory MM. Methods: Patients with progressing, measurable, proteasome inhibitor-refractory MM (IMWG criteria) were included in this multicenter phase II trial. Further selection criteria included WHO performance status ≤ 3, platelets ≥ 50 x 109/L, hemoglobin ≥ 80 g/L (both may be achieved by transfusion) and adequate hepatic function. Concomitant use of other anti-cancer medication or radiotherapy, except for local pain control, was excluded. Patient age or prior number or types of therapy were not limited. Simon's two stage design was used to differentiate a promising activity (best response at any time point, partial response (PR) or better, ≥ 35 %) from an uninteresting activity (≤ 15% PR; power 80%, alpha 5%). Results: 34 patients were treated with oral nelfinavir 2500 mg days 1-14 b.i.d. in combination with bortezomib + dexamethasone (BTZ 1.3 mg/m2 days 1, 4, 8, 11, dexamethasone 20 mg p.o. days 1-2, 4-5, 8-9, 11-12) for a maximum of 6 21-day cycles at 9 SAKK trial sites throughout Switzerland. Patients (median age 67.5 years, range 42-82 years) had a median of 5 (range 2-12) prior therapy lines, 26 (76%) patients had prior high dose chemotherapy, and 13 (39%) had known poor prognosis cytogenetic abnormalities. All treated patients had proteasome inhibitor refractory MM according to IMWG criteria, i.e. they had progressed during or within 60 days after adequately dosed proteasome inhibitor-containing therapy. Moreover, 26 (76%) patients werelenalidomide-refractory by IMWG criteria (double refractory). Trial therapy is still ongoing in 2 patients. The median number of treatment cycles delivered per patient is 4. 22 patients achieved an objective response with a PR or better, resulting in an overall response rate (OR) of 65% (90% CI 49.2%-75.7%) to date. VGPR was reached in 5 patients, PR in 17 patients, MR in 3 patients, SD in 4 patients and PD in 3. Inpatients double-refractory for proteasome inhibitors andlenalidomide, the OR was 69%, in patients with poor prognosis cytogenetic abnormalities it was 77%. The OR was independent from the number of prior therapy lines (OR rate 69% with < 5 prior therapy lines, OR rate 61% with ≥ 5 prior lines). Most frequent > grade (G) 2 adverse events to date were anemia (G3 29%), thrombocytopenia (G3 24%, G4 18%), infections (G3 24%, G4 9%, G5 3%), hyperglycemia (G3 18%, G4 3%) and fatigue (G3 12%). Six patients maintained their PR or better for the full 6 cycles per protocol while on study. Four patients continuedNVd therapy on a compassionate use basis after completing the study. Updated final data will be provided at the meeting. Conclusion: Nelfinavir in combination with bortezomib and dexamethasone (NVd) is a reasonable, active, safe and widely available treatment option for patients with proteasome inhibitor-refractory multiple myeloma. The objective response rate of 65% observed in this very advanced, heavily pretreated, mostly dual-refractory patient population is exceptional. Our results warrant further development of nelfinavir as a sensitizing drug for proteasome inhibitor-based treatments and promising new agent for MM therapy.

Background Bevacizumab (BEV)-containing therapies are costly. We performed a health economic analysis of a randomized phase 3 study (SAKK 41/06) that compared BEV continuation as a single agent (BEV) with treatment holidays (no BEV) after completing 4 to 6 cycles of first-line chemotherapy plus BEV in metastatic colorectal cancer patients. Patients and Methods Costs for first-line chemotherapy with BEV, BEV continuation therapy, hospitalizations (length of stay), control visits, diagnostic tests, and second-line and later rounds of chemotherapy were collected. Mean costs per patient per treatment arm and an incremental cost-effectiveness ratio were calculated. Probabilistic sensitivity analysis was performed to account for uncertainty in the input parameters. Results The total incurred mean costs per patient were 126,631 Swiss francs (CHF) [95% confidence interval (CI), 116,521-136,740] for BEV versus CHF100,146 (95% CI, 92,811-107,481) for no BEV. The incremental cost effectiveness ratio was CHF108,991 per life-year gained (LYG; 95% CI from probabilistic sensitivity analysis, 62,890-248,515). Compared to a willingness-to-pay threshold of CHF100,000/LYG, there was 42% probability that BEV continuation was cost effective, which decreased to 20% at a threshold of CHF75,000/LYG. Economic equality was reached in only 0.07% of cases. Conclusion The clinical conclusion that BEV continuation as a single agent after completion of first-line chemotherapy is of low therapeutic value is supported by this health economic analysis. Costs increase without significant clinical benefit in this setting.

Transfusion-associated graft-versus-host disease can occur in both immunocompetent and immunocompromised hosts. Cladribine is a synthetic analogue of adenine used in the treatment of lymphoid malignancies, commonly associated with a decrease in T lymphocytes. Cladribine was given for a low-grade non-Hodgkin's lymphoma with thrombocytopenia as the main side-effect. Six units of pooled non-irradiated platelets were transfused from six unrelated donors; 10 d later a clinical picture typical of graft-versus-host disease resulted. Polymerase chain reaction of the highly polymorphic DNA minisatellites and HLA-DR oligotyping were used to demonstrate the exogenous DNA. In the patient's blood and tissues, only the pattern of donor 5 was found. The patient (DRB1*0301/1101; DRB3*0101/02) and this donor (DRB1*0301/1104; DRB3*02) by chance shared a partial common haplotype. This complication highlights the sensitivity of DNA minisatellite analysis. It further raises the question of transfusion and of prophylactic irradiation of all blood products in immunosuppressed patients and those treated with cladribine. This case represents a previously unreported situation where an immunosuppressed patient was able to eliminate cells from five totally HLA-DR dissimilar donors but not from one heterozygous donor with strong HLA-DR similarity.

269 Background: TTFields are alternating electric fields delivered to the region of the tumor by means of non-invasive transducer arrays. TTFields interfere with mitotic spindle formation, thus having an anti-mitotic activity. In pancreatic cancer, TTFields decreased proliferation and clonogenic potential in vitro, and reduced tumor volume in vivo. The PANOVA trial was designed to test TTFields, combined with chemotherapy, in pancreatic cancer. Methods: Twenty patients with advanced pancreatic adenocarcinoma were enrolled in a prospective, single arm study of TTFields at 150 kHz, concomitant with standard weekly gemcitabine. All patients had histologically-confirmed unresectable tumors, with an ECOG performance score of 0-1 and no prior chemotherapy or radiation therapy. The primary endpoint was incidence and severity of treatment emergent adverse events (AEs). Secondary endpoints included progression free survival (PFS), PFS rate at 6 months, overall survival (OS) and response rate. Results: The median age was 73 (range – 49-81) and 60% of the patients were females. Most patients (80%) had an ECOG score of 1. Twelve patients (60%) had distant metastases, while the others had locally advanced disease. Median compliance with TTFields was 78% (14 hours/day), with median duration of 5 months. Fourteen patients (70%) had serious (grade 3-5) AEs during the study period. Six patients (30%) had hematological, 45% gastrointestinal and 15% pulmonary AEs. Ten patients (50%) had treatment-related skin toxicity, of which only 2 were grade 3, both resolved with appropriate treatment. No TTFields-related serious AEs were reported. The median PFS was 8.3 months (95% CI 4.3, 10.3). PFS rate at 6 months was 56%. Of the evaluable tumors, 30% had partial response and another 30% stable disease. The median OS was 14.9 months and 1-year survival rate was 55%. Conclusions: TTFields concomitant to gemcitabine are tolerable and safe for advanced pancreatic cancer patients. The efficacy results are promising and support further research in this indication. An extension of the PANOVA protocol, including 20 additional patients who receive gemcitabine, nab-paclitaxel and TTFields is ongoing. Clinical trial information: NCT01971281.

Purpose: The EGF receptor (EGFR) is overexpressed in the majority of metastatic castration-resistant prostate cancers (mCRPC) and might represent a valid therapeutic target. The combination of docetaxel and cetuximab, the monoclonal antibody against EGFR, has not been tested in patients with prostate cancer. Experimental Design: Patients with mCRPC progressing during or within 90 days after at least 12 weeks of docetaxel were included in this phase II trial. Treatment consisted of docetaxel (75 mg/m2 every 3 weeks or 35 mg/m2 on days 1, 8, 15 every 4 weeks) in combination with cetuximab (400 mg/m2 on day 1 and then 250 mg/m2 weekly). The primary endpoint was progression-free survival (PFS) at 12 weeks defined as the absence of prostate-specific antigen (PSA), radiographic, or clinical progression. Evaluation of known biomarkers of response and resistance to cetuximab (EGFR, PTEN, amphiregulin, epiregulin) was conducted. Results: Thirty-eight patients were enrolled at 15 Swiss centers. Median age was 68 years and median PSA was 212 ng/mL. PFS at 12 weeks was 34% [95% confidence interval (CI), 19%–52%], PFS at 24 weeks was 20%, and median overall survival (OS) was 13.3 months (95% CI, 7.3–15.4). Seven patients (20%) had a confirmed ≥50% and 11 patients (31%) a confirmed ≥30% PSA decline. About 47% of enrolled patients experienced grade 3 and 8% grade 4 toxicities. A significantly improved PFS was found in patients with overexpression of EGFR and persistent activity of PTEN. Conclusions: EGFR inhibition with cetuximab might improve the outcome of patients with mCRPC. A potential correlation between EGFR overexpression, persistent expression of PTEN, and EGFR inhibition should be investigated further. Clin Cancer Res; 18(21); 6049–57. ©2012 AACR.

The treatment of multiple myeloma has undergone significant changes in the recent past. The arrival of novel agents, especially thalidomide, bortezomib and lenalidomide, has expanded treatment options and patient outcomes are improving significantly. This article summarises the discussions of an expert meeting which was held to debate current treatment practices for multiple myeloma in Switzerland concerning the role of the novel agents and to provide recommendations for their use in different treatment stages based on currently available clinical data. Novel agent combinations for the treatment of newly diagnosed, as well as relapsed multiple myeloma are examined. In addition, the role of novel agents in patients with cytogenetic abnormalities and renal impairment, as well as the management of the most frequent side effects of the novel agents are discussed. The aim of this article is to assist in treatment decisions in daily clinical practice to achieve the best possible outcome for patients with multiple myeloma.

Non-small-cell lung cancer is the most common cause of cancer-related death worldwide. Surgery remains the cornerstone of treatment for localized, resectable lung cancer, although advanced stages are associated with a high risk of developing distant metastases. Large randomized trials have demonstrated an improvement in survival with additional chemotherapy administered before or after surgical intervention. Several meta-analyses have shown improved survival for adjuvant and neoadjuvant chemotherapy. This review discusses the data on adjuvant and neoadjuvant chemotherapy for resectable non-small-cell lung cancer and focuses especially on the advantages and disadvantages of induction treatment of operable stage IIIA N2 diseases.

The association of simian virus 40 (SV40) with malignant pleural mesothelioma is currently under debate. In some malignancies of viral aetiology, viral DNA can be detected in the patients' serum or plasma. To characterize the prevalence of SV40 in Swiss mesothelioma patients, we optimized a real-time PCR for quantitative detection of SV40 DNA in plasma, and used a monoclonal antibody for immunohistochemical detection of SV40 in mesothelioma tissue microarrays. Real-time PCR was linear over five orders of magnitude, and sensitive to a single gene copy. Repeat PCR determinations showed excellent reproducibility. However, SV40 status varied for independent DNA isolates of single samples. We noted that SV40 detection rates by PCR were drastically reduced by the implementation of strict room compartmentalization and decontamination procedures. Therefore, we systematically addressed common sources of contamination and found no cross-reactivity with DNA of other polyomaviruses. Contamination during PCR was rare and plasmid contamination was infrequent. SV40 DNA was reproducibly detected in only 4 of 78 (5.1%) plasma samples. SV40 DNA levels were low and not consistently observed in paired plasma and tumour samples from the same patient. Immunohistochemical analysis revealed a weak but reproducible SV40 staining in 16 of 341 (4.7%) mesotheliomas. Our data support the occurrence of non-reproducible SV40 PCR amplifications and underscore the importance of proper sample handling and analysis. SV40 DNA and protein were found at low prevalence (5%) in plasma and tumour tissue, respectively. This suggests that SV40 does not appear to play a major role in the development of mesothelioma.
