Abstract
BACKGROUND Lung cancer screening with low-dose chest CT (LDCT) reduces the mortality of eligible individuals. Blood signatures might act as a standalone screening tool, refine the selection of patients at risk, or help to classify undetermined nodules detected on LDCT. We previously showed that circulating tumour cells (CTCs) could be detected, using the isolation by size of epithelial tumour cell technique (ISET), long before the cancer was diagnosed radiologically. We aimed to test whether CTCs could be used as a biomarker for lung cancer screening. METHODS We did a prospective, multicentre, cohort study in 21 French university centres. Participants had to be eligible for lung cancer screening as per National Lung Screening Trial criteria and have chronic obstructive pulmonary disease with a fixed airflow limitation defined as post-bronchodilator FEV1/FVC ratio of less than 0·7. Any cancer, other than basocellular skin carcinomas, detected within the previous 5 years was the main exclusion criterion. Participants had three screening rounds at 1-year intervals (T0 [baseline], T1, and T2), which involved LDCT, clinical examination, and a blood test for CTCs detection. Participants and investigators were masked to the results of CTC detection, and cytopathologists were masked to clinical and radiological findings. Our primary objective was to test the diagnostic performance of CTC detection using the ISET technique in lung cancer screening, compared with cancers diagnosed by final pathology, or follow up if pathology was unavailable as the gold standard. This study is registered with ClinicalTrials.gov identifier, number NCT02500693. FINDINGS Between Oct 30, 2015, and Feb 2, 2017, we enrolled 614 participants, predominantly men (437 [71%]), aged 65·1 years (SD 6·5), and heavy smokers (52·7 pack-years [SD 21·5]). 81 (13%) participants dropped out between baseline and T1, and 56 (11%) did between T1 and T2. Nodules were detected on 178 (29%) of 614 baseline LDCTs. 19 participants (3%) were diagnosed with a prevalent lung cancer at T0 and 19 were diagnosed with incident lung cancer (15 (3%) of 533 at T1 and four (1%) of 477 at T2). Extrapulmonary cancers were diagnosed in 27 (4%) of participants. Overall 28 (2%) of 1187 blood samples were not analysable. At baseline, the sensitivity of CTC detection for lung cancer detection was 26·3% (95% CI 11·8-48·8). ISET was unable to predict lung cancer or extrapulmonary cancer development. INTERPRETATION CTC detection using ISET is not suitable for lung cancer screening.

Swiss medical weekly. 2020;:w20176
Abstract
BACKGROUND In recent years, several treatment modalities have proved to be effective in the treatment of neuroendocrine tumours (NETs). However, there is currently no consensus on the sequence in which these options are best used. METHODS In this observational study, we analysed the treatment modalities and sequences of all patients included in the Swiss NeuroEndocrine Tumour registry (SwissNET). SwissNET is a national registry, which has prospectively included patients with a NET from all regions of Switzerland since 2008. RESULTS The registry includes 1366 patients; 1063 had documented therapies after the main diagnosis and were included in the analysis. The median follow-up time was 1.86 years. The most common primary site was the small intestine (291 patients, 27%) followed by pancreas (254 patients, 24%), lung (172 patients, 16%) and appendix (163 patients, 15%). A total of 167 different therapy sequences were observed. In 708 (67%) patients, surgery was the only treatment. The sequence of surgery followed by chemotherapy was most frequently documented in poorly (G3) differentiated (24 patients, 60%) and pancreatic (15 patients, 34%) NETs. Tumours treated with surgery followed by biotherapy or followed by peptide receptor radionuclide therapy (PRRT) were predominantly well-differentiated G1 NETs of the small intestine. In patients who were treated with either PRRT or systemic therapy (chemotherapy or molecular therapy) or both, PRRT was used more frequently than systemic therapy in patients with a small intestinal NET (35 patients, 62% vs 30, 54%), whereas the opposite held true in pancreatic (44 patients, 59% vs 56, 70%) and lung NETs (6 patients, 14% vs 40, 97%). If both chemotherapy and molecular therapy were used, chemotherapy was applied prior to molecular therapy in 13 of 19 (68%) patients with a pancreatic NET. CONCLUSION Surgery represents the treatment of choice in most patients with a NET irrespective of tumour stage. In patients receiving additional treatment, an impressive variety of treatment sequences were documented. In small intestinal NETs, patients received PRRT more often than chemotherapy, whereas the opposite holds true for patients with pancreatic and lung NETs.

Abstract
The aim of this study was to investigate the association between BMI (kg/m) and prostate cancer risk. BMI is a modifiable lifestyle factor and may provide a unique opportunity for primary prevention of prostate cancer if a causal association exists. Data from 11 886 men from the Carotene and Retinol Efficacy Trial (CARET, 1985-1996 with active follow-up through 2005) comprising current and former heavy smokers were analyzed. CARET was a multicenter randomized, double-blind placebo-controlled chemoprevention trial testing daily supplementation of 30 mg β-carotene+25 000 IU retinyl palmitate for primary prevention of lung cancer. Prostate cancer was a secondary outcome. Nonaggressive disease was defined as Gleason less than 7 and stage I/II. Aggressive disease was primarily defined as at least Gleason 7 or stage III/IV, and secondarily by excluding Gleason 3+4 from the first definition. BMI was calculated from measured weight and height. Cox proportional hazards regression models were used to estimate hazard ratios (HRs) with 95% confidence intervals (CIs) for cancer incidence between BMI categories. During follow-up, 883 men were diagnosed with prostate cancer. In the analysis of aggressive disease when Gleason 3+4 was excluded, men with a BMI of at least 35 kg/m had an increased rate of prostate cancer (HR: 1.80, 95% CI: 1.04-3.11, Ptrend=0.04) compared with men with BMI 18-24.9 kg/m. No other differences were seen in risk estimates for overall, nonaggressive or aggressive prostate cancer including all Gleason 7 cases, between BMI categories. Our results show an association between having a BMI of at least 35 kg/m and an increased risk of aggressive prostate cancer (not including Gleason 3+4 tumors), but do not support an association between BMI and risk of overall, aggressive disease including all Gleason 7, or nonaggressive prostate cancer within a population of current and former heavy smokers.

Abstract
Two phase 1, open-label studies assessed the impact of food or gastric pH modification (omeprazole) on the exposure and safety/tolerability of osimertinib and its metabolites. The food effect study was an open-label, 2-period crossover study in patients with advanced non-small-cell lung cancer, randomized into 2 treatment sequences: single-dose osimertinib 80 mg in a fed then fasted state or fasted then fed. The gastric pH study was an open-label, 2-period fixed sequence study assessing the effect of omeprazole on osimertinib exposure in healthy male volunteers. In period 1, volunteers received omeprazole 40 mg (days 1-4), then omeprazole 40 mg plus osimertinib 80 mg (day 5). In period 2, volunteers received osimertinib 80 mg alone (single dose). Blood samples were collected at prespecified time points for pharmacokinetic analyses. Safety/tolerability was also assessed. In the food effect study 38 patients were randomized to fed/fasted (n = 18) or fasted/fed (n = 20) sequences with all patients completing treatment. Coadministration with food did not affect osimertinib exposure (geometric least-squares mean ratios [90% confidence intervals]: 106.05% [94.82%, 118.60%] [area under the plasma concentration time curve from zero to 72 hours] and 92.75% [81.40%, 105.68%] [maximum plasma concentration]). In the gastric pH study (n = 68 received treatment, n = 47 completed the study), coadministration with omeprazole did not affect osimertinib exposure (geometric least-squares mean ratios 106.66% [100.26%, 113.46%] [area under the concentration-time curve], 101.65% [94.65%, 109.16%] [peak concentration]). Osimertinib was well tolerated in both studies. Osimertinib may be administered without regard to food. Dose restriction is not required in patients whose gastric pH may be altered by concomitant agents or medical conditions. ClinicalTrials.gov: NCT02224053, NCT02163733.

Abstract
OBJECTIVE Chemotherapy with irinotecan plus cisplatin has shown promise in chemo-naïve small-cell lung cancer (SCLC) patients. However, irinotecan treatment for relapsed or refractory SCLC has not been adequately evaluated. This phase II study evaluated the appropriate treatment schedule of irinotecan as a single agent. This study was designed to determine the antitumor activity, toxicity, and survival in previously treated SCLC patients. METHODS Previously treated SCLC patients with at least one platinum-based regimen received irinotecan (100 mg/m2) on days 1 and 8, every 3 weeks, until disease progression. The assessment of the response rate was the primary endpoint. RESULTS Thirty patients were enrolled, with an objective response rate of 41.3% (95% confidence interval [CI] 25.5-59.3), and a disease control rate of 69%. Median progression-free and overall survival was 4.1 months (95% CI, 2.2-5.4) and 10.4 months (95% CI, 8.1-14), respectively. The grade 3/4 hematological toxicities were neutropenia (36.7%), thrombocytopenia (3.3%), anemia (13.3%), and febrile neutropenia (6.6%). There were no grade 4 nonhematological toxicities. Frequent grade 3 nonhematological toxicities included diarrhea (10%), anorexia (6.6%), and hyponatremia (6.6%). CONCLUSIONS This phase II study showed a high objective response rate and long survival. Irinotecan monotherapy schedule used was well tolerated, and could be an active treatment option for these patients.

Abstract
BACKGROUND BTH1677, a beta-glucan pathogen-associated molecular pattern molecule, drives an anti-cancer immune response in combination with oncology antibody therapies. This phase II study explored the efficacy, pharmacokinetics (PK), and safety of BTH1677 combined with bevacizumab/carboplatin/paclitaxel in patients with untreated advanced non-small cell lung cancer (NSCLC). METHODS Patients were randomized to the BTH1677 arm (N = 61; intravenous [IV] BTH1677, 4 mg/kg, weekly; IV bevacizumab, 15 mg/kg, once each 3-week cycle [Q3W]; IV carboplatin, 6 mg/mL/min Calvert formula area-under-the-curve, Q3W; and IV paclitaxel, 200 mg/m2, Q3W) or Control arm (N = 31; bevacizumab/carboplatin/paclitaxel as above). Carboplatin/paclitaxel was discontinued after 4-6 cycles and patients who responded or remained stable received maintenance therapy with BTH1677/bevacizumab (BTH1677 arm) or bevacizumab (Control arm). Efficacy assessments, based on blinded central radiology review, included objective response rate (ORR; primary endpoint), disease control rate, duration of objective response, and progression-free survival. Overall survival and adverse events (AEs) were also assessed. RESULTS ORR was higher in the BTH1677 vs Control arm but the difference between groups was not statistically significant (60.4% vs 43.5%; P = .2096). All other clinical endpoints also favored the BTH1677 arm but none statistically differed between arms. PK was consistent with previous studies. Although a higher incidence of Grade 3/4 AEs occurred in the BTH1677 vs Control arm (93.2% vs 66.7%), no unexpected AEs were observed. Serious AEs and discontinuations due to AEs were lower in the BTH1677 vs Control arm. CONCLUSIONS Improvements in tumor assessments and survival were observed with BTH1677/bevacizumab/carboplatin/paclitaxel compared with control treatment in patients with advanced NSCLC. TRIAL REGISTRATION ClinicalTrials.gov registration ID: NCT00874107 . Registered 2 April 2009. First participant was enrolled on 29 September 2009.

Abstract
BACKGROUND Docetaxel/cisplatin (DP) and gemcitabine/cisplatin (GP) are standard treatment regimens for advanced non-small cell lung cancer (NSCLC). In spite of potent efficacy, the conventional 1-day DP is regarded as having more toxicity as compared with GP. There is increasing interest in a biweekly split administration of DP to reduce its toxicity. Hypothesis was that first-line biweekly DP is as safe as GP in the elderly or poor performance status (PS) patients. METHODS Chemotherapy-naïve patients with advanced NSCLC (IIIB/IV) who were elderly (65<) or PS (ECOG 2) were randomized to DP or GP arm by balancing for ECOG (0-1 vs. 2) and stage (IIIB vs. IV). DP comprised docetaxel (35 mg/m2)/cisplatin (30 mg/m2) iv on days 1 and 8, every 3 weeks. GP comprised gemcitabine (1000 mg/m2)/cisplatin (30 mg/m2) iv on days 1 and 8, every 3 weeks. Chemotherapy lasted up to 4-6 cycles or until progression. Primary endpoint was safety (proportion of grade 3/4 toxicities). Planned sample size was 49 patients in each arm. RESULTS From November 2009 to August 2012, a total of 99 patients were randomized (DP 50/GP 49) from nine institutions. Adenocarcinoma and squamous cell carcinoma were observed in 62% and 33% of patients, respectively. Toxicity profiles were comparable for both arms and the differences were not statistically significant except for anemia and leucocytopenia. Any grade of anemia (86 vs. 98%) and of leucocytopenia (18 vs. 43%) was more common in the GP arm with statistical significance. Oral mucositis tended to be predominant in the DP arm. Patients in the DP arm (51%) suffered grade 3 or higher toxicities as did 47% in the GP arm (47%). The most common grade 3 or higher toxicities were as follows: In the DP arm, neutropenia (8%), leucopenia (8%), anemia (4%), pneumonia with normal ANC (4%) and febrile neutropenia (2%) were observed. In the GP arm, anemia (15%), neutropenia (15%), pneumonia with normal ANC (4%), thrombocytopenia (4%) and leucopenia (2%) were observed. The best overall response rates (CR + PR) for the DP and GP arms were 20.0 and 21% with no CR, respectively, and disease control rates (CR + PR + SD) were 70.0 and 76%, respectively. Median progression-free survival and median overall survival were 3.7 and 14.9 months in the DP arm and 5.6 and 20.8 months in the GP arm, respectively. CONCLUSION This study showed that DP is similar to GP in terms of efficacy and toxicity in treatment of elderly or poor performance patients. Both regimens showed similar grade 3/4 toxicities with different profiles.

Abstract
PURPOSE To assess the feasibility of measuring symptomatic adverse events (AEs) in a multicenter clinical trial using the National Cancer Institute's Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE). METHODS AND MATERIALS Patients enrolled in NRG Oncology's RTOG 1012 (Prophylactic Manuka Honey for Reduction of Chemoradiation Induced Esophagitis-Related Pain during Treatment of Lung Cancer) were asked to self-report 53 PRO-CTCAE items representing 30 symptomatic AEs at 6 time points (baseline; weekly ×4 during treatment; 12 weeks after treatment). Reporting was conducted via wireless tablet computers in clinic waiting areas. Compliance was defined as the proportion of visits when an expected PRO-CTCAE assessment was completed. RESULTS Among 226 study sites participating in RTOG 1012, 100% completed 35-minute PRO-CTCAE training for clinical research associates (CRAs); 80 sites enrolled patients, of which 34 (43%) required tablet computers to be provided. All 152 patients in RTOG 1012 agreed to self-report using the PRO-CTCAE (median age 66 years; 47% female; 84% white). Median time for CRAs to learn the system was 60 minutes (range, 30-240 minutes), and median time for CRAs to teach a patient to self-report was 10 minutes (range, 2-60 minutes). Compliance was high, particularly during active treatment, when patients self-reported at 86% of expected time points, although compliance was lower after treatment (72%). Common reasons for noncompliance were institutional errors, such as forgetting to provide computers to participants; patients missing clinic visits; Internet connectivity; and patients feeling "too sick." CONCLUSIONS Most patients enrolled in a multicenter chemoradiotherapy trial were willing and able to self-report symptomatic AEs at visits using tablet computers. Minimal effort was required by local site staff to support this system. The observed causes of missing data may be obviated by allowing patients to self-report electronically between visits, and by using central compliance monitoring. These approaches are being incorporated into ongoing studies.

Abstract
BACKGROUND Cabazitaxel, a semisynthetic microtubule inhibitor, has shown antitumour activity in models resistant to paclitaxel and docetaxel, and it has been approved for the treatment of docetaxel-resistant prostate cancer. We investigated its activity in patients with advanced non-small-cell lung cancer (NSCLC) progressing under or after docetaxel-based regimens. METHODS Patients with locally advanced unresectable or metastatic NSCLC, with an Eastern Cooperative Oncology Group performance status of 0-2, were enrolled; patients had to have received up to two prior chemotherapy regimens for the treatment of advanced disease, including one docetaxel-containing regimen. Treatment consisted of cabazitaxel (25 mg m(-2) intravenously, every 21 days) until disease progression. The primary end point was the overall response rate. RESULTS Among the 46 evaluable patients, 28.3% had squamous cell carcinoma and 54.3% had adenocarcinoma. Eight (17.4%) patients had received one and 38 (82.6%) two prior chemotherapy regimens. Treatment compliance was 95%; 26 (16%) cycles were delayed because of toxicity, (n=13) and dose reduction was required in 6 (13%) patients because of haematologic toxicity. Six (13%) patients achieved a partial response and 17 (37.0%) stable disease. The median progression-free survival and overall survival were 2.1 (95% confidence interval (CI): 1.0-3.2) and 7.4 (95% CI: 5.2-9.6) months, respectively. Grade 4 adverse events included neutropenia (n=8; 17%), febrile neutropenia (n=6; 13%) and thrombocytopenia (n=3; 6.5%). There was one treatment-related death. CONCLUSIONS Cabazitaxel exhibits activity in NSCLC patients pre-treated with docetaxel-based chemotherapy with a substantial but manageable toxicity profile. The drug merits further evaluation in this indication.

Abstract
AIM: Providing epidemiological data and treatment of anemia in lung cancer patients undergoing first-line chemotherapy. METHODS Epidemiological, observational, retrospective and multicenter study carried out at 30 sites throughout Spain. RESULTS The prevalence of anemia (hemoglobin [Hb] level <12 g/dl) was 18.3% and the incidence 80.7%. Mean Hb levels were 13.4 g/dl (95% Cl: 13.2-13.6) and 11.5 g/dl (95% Cl: 11.3-11.7) at starting and at the end of chemotherapy, respectively. Of the 294 patients with anemia, 174 (59.2%) were treated. Erythropoiesis-stimulating agents were given to 90.2% patients, alone in 31.6% and combined iron in 39.7%, transfusion in 9.2% and iron and transfusion in 9.8%. CONCLUSION These results suggest an appropriate and rational use of erythropoiesis-stimulating agents in the treatment of chemotherapy-associated anemia in lung cancer patients. [corrected].
