Achieving Thoracic Oncology data collection in Europe: a precursor study in 35 Countries

Background: A minority of European countries have participated in international comparisons with high level data on lung cancer. However, the nature and extent of data collection across the continent is simply unknown, and without accurate data collection it is not possible to compare practice and set benchmarks to which lung cancer services can aspire. Methods: Using an established network of lung cancer specialists in 37 European countries, a survey was distributed in December 2014. The results relate to current practice in each country at the time, early 2015. The results were compiled and then verified with co-authors over the following months. Results: Thirty-five completed surveys were received which describe a range of current practice for lung cancer data collection. Thirty countries have data collection at the national level, but this is not so in Albania, BosniaHerzegovina, Italy, Spain and Switzerland. Data collection varied from paper records with no survival analysis, to well-established electronic databases with links to census data and survival analyses. Conclusion: Using a network of committed clinicians, we have gathered validated comparative data reporting an observed difference in data collection mechanisms across Europe. We have identified the need to develop a welldesigned dataset, whilst acknowledging what is feasible within each country, and aspiring to collect high quality data for clinical research

Efficacy and safety of nivolumab for patients with pre-treated type B3 thymoma and thymic carcinoma: results from the EORTC-ETOP NIVOTHYM phase II trial

Immunotherapy; Thymic carcinoma; ThymomaImmunoteràpia; Carcinoma tímic; TimomaInmunoterapia; Carcinoma tímico; TimomaBackground Thymic malignancies are rare intrathoracic tumors, which may be aggressive and difficult to treat. They represent a therapeutic challenge in the advanced/metastatic setting, with limited treatment options after the failure of first-line platinum-based chemotherapy. They are frequently associated with autoimmune disorders that also impact oncological management. Materials and methods NIVOTHYM is an international, multicenter, phase II, two-cohort, single-arm trial evaluating the activity and safety of nivolumab [240 mg intravenously (i.v.) q2 weeks] alone or with ipilimumab (1 mg /kg i.v. q6 weeks) in patients with advanced/relapsed type B3 thymoma or thymic carcinoma, after exposure to platinum-based chemotherapy. The primary endpoint is progression-free survival rate at 6 months (PFSR-6) based on RECIST 1.1 as per independent radiological review. Results From April 2018 to February 2020, 55 patients were enrolled in 15 centers from 5 countries. Ten patients (18%) had type B3 thymoma and 43 (78%) had thymic carcinoma. The majority were male (64%), and the median age was 58 years. Among the 49 eligible patients who started treatment, PFSR-6 by central review was 35% [95% confidence interval (CI) 22% to 50%]. The overall response rate and disease control rate were 12% (95% CI 5% to 25%) and 63% (95% CI 48% to 77%), respectively. Using the Kaplan–Meier method, median progression-free survival and overall survival by local assessment were 6.0 (95% CI 3.1-10.4) months and 21.3 (95% CI 11.6-not estimable) months, respectively. In the safety population of 54 patients, adverse events (AEs) of grade 1/2 were observed in 22 (41%) patients and grade 3/4 in 31 (57%) patients. Treatment-related AEs of grade 4 included one case of neutropenia, one case of immune-mediated transaminitis, and two cases of myocarditis. Conclusions Nivolumab monotherapy demonstrated an acceptable safety profile and objective activity, although it has been insufficient to meet its primary objective. The second cohort of NIVOTHYM is currently ongoing to assess the combination of nivolumab plus ipilimumab

Results of screening in early and advanced thoracic malignancies in the EORTC pan-European SPECTAlung platform

Cancer screening; Non-small-cell lung cancerCribado de cáncer; Cáncer de pulmón de células no pequeñasCribratge de càncer; Càncer de pulmó no de cèl·lules petitesAccess to a comprehensive molecular alteration screening is patchy in Europe and quality of the molecular analysis varies. SPECTAlung was created in 2015 as a pan-European screening platform for patients with thoracic malignancies. Here we report the results of almost 4 years of prospective molecular screening of patients with thoracic malignancies, in terms of quality of the program and molecular alterations identified. Patients with thoracic malignancies at any stage of disease were recruited in SPECTAlung, from June 2015 to May 2019, in 7 different countries. Molecular tumour boards were organised monthly to discuss patients’ molecular and clinical profile and possible biomarker-driven treatments, including clinical trial options. FFPE material was collected and analysed for 576 patients with diagnosis of pleural, lung, or thymic malignancies. Ultimately, 539 patients were eligible (93.6%) and 528 patients were assessable (91.7%). The turn-around time for report generation and molecular tumour board was 214 days (median). Targetable molecular alterations were observed in almost 20% of cases, but treatment adaptation was low (3% of patients). SPECTAlung showed the feasibility of a pan-European screening platform. One fifth of the patients had a targetable molecular alteration. Some operational issues were discovered and adapted to improve efficiency.This publication was supported by Fonds Baillet Latour from Belgium and Walgreens Boots Alliance

A Phase III Randomized Study Comparing a Chemotherapy with Cisplatin and Etoposide to a Etoposide Regimen without Cisplatin for Patients with Extensive Small-Cell Lung Cancer

IntroductionIn a literature meta-analysis, we showed survival benefits for regimens including cisplatin [hazard ratio (HR) 0.61; 95% confidence interval (CI), 0.57–0.66] and for those including etoposide (HR 0.65; 0.61–0.69). That benefit was mainly observed when etoposide alone or in combination with cisplatin was included in the chemotherapy regimens. Our objective was to determine if chemotherapy with both drugs improves survival in comparison to a non-platinum regimen with etoposide.MethodsExtensive small-cell lung cancer patients were randomized between cisplatin–etoposide (CE) and ifosfamide + etoposide + epirubicin regimen (IVE) between 2000 and 2013.Results176 and 170 eligible patients were allocated to CE and IVE (315 deaths were required before analysis), respectively. Objective response rates were not significantly different: 60% with CE and 59% with IVE. No statistically significant difference in median survival and 1-year and 2-year was observed with rates of 9.6 months, 31 and 5% for CE and 10 months, 39 and 9% for IVE, respectively. HR was 0.84 (95% CI 0.68–1.05, p = 0.16). Only two prognostic factors for survival were retained in multivariate analysis: sex with HR = 0.69 (95% CI 0.49–0.97, p = 0.03) and performance status with HR = 0.53 (95% CI 0.49–0.97, p < 0.0001). After adjustment for these prognostic factors, HR for survival was 0.83 (95% CI 0.65–1.08, p = 0.17). There was more thrombopenia in the CE regimen and more leukopenia with IVE.ConclusionCombination of CE failed to improve survival in comparison to an etoposide-containing regimen without cisplatin.Clinical Trial Registrationhttps://clinicaltrials.gov/ct2/show/NCT00658580?term=ELCWP+01994&rank=1, identifier NCT00658580

Phase I trial of volasertib, a Polo-like kinase inhibitor, plus platinum agents in solid tumors: safety, pharmacokinetics and activity

Summary: Background This trial evaluated the maximum tolerated dose (MTD), safety, pharmacokinetics, and activity of volasertib, a selective Polo-like kinase 1 inhibitor that induces mitotic arrest and apoptosis, combined with cisplatin or carboplatin in patients with advanced/metastatic solid tumors (NCT00969761; 1230.6). Methods Sequential patient cohorts (3+3 dose-escalation design) received a single infusion of volasertib (100-350 mg) with cisplatin (60-100 mg/m2) or carboplatin (area under the concentration versus time curve [AUC]4-AUC6) on day 1 every 3 weeks for up to six cycles. Sixty-one patients received volasertib/cisplatin (n=30) or volasertib/carboplatin (n=31) for a median of 3.5 (range, 1-6) and 2.0 (range, 1-6) treatment cycles, respectively. Results The most common cycle 1 dose-limiting toxicities (DLTs) were thrombocytopenia, neutropenia and fatigue. MTDs (based on cycle 1 DLTs) were determined to be volasertib 300 mg plus cisplatin 100 mg/m2 and volasertib 300 mg plus carboplatin AUC6. Co-administration did not affect the pharmacokinetics of each drug. Partial responses were observed in two patients in each arm. Stable disease was achieved in 11 and six patients treated with volasertib/cisplatin and volasertib/carboplatin, respectively. Conclusions Volasertib plus cisplatin or carboplatin at full single-agent doses was generally manageable and demonstrated activity in heavily pretreated patients with advanced solid tumors.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

Current management of limited-stage SCLC and CONVERT trial impact:Results of the EORTC Lung Cancer Group survey

Objectives: The CONVERT trial showed that twice-daily (BD) concurrent chemoradiotherapy should continue tobe considered the standard of care in localised LS-SCLC. A survey was conducted to assess the impact of theCONVERT trial in clinical practice and to identify any relevant research questions for future trials in this setting.Methods and materials: An EORTC Group online survey of LS-SCLC practice was distributed to the EORTC LCGand to members of several European thoracic oncology societies between April and December 2018.Results: 198 responses were analysed. The majority of respondents (88%, n=174) were aware of the CONVERTtrial. Radiation oncologists comprised 56% of all respondents. Once-daily (OD) radiotherapy is still the mostcommonly used regimen, however the use of concurrent BD radiotherapy increased after the publication ofCONVERT (n=59/186, 32% prior to and n=78/187, 42% after the publication, p=0.053). The main reasonsfor not implementing BD after the CONVERT publication were logistical issues (n=88, 44%), inconvenience forpatients (n=56, 28%), and the absence of a statistical survival difference between the two arms in CONVERT(n=38, 19%). Brain MRI was used by 28% during staging but more than half (60%) of the respondents did notroutinely image the brain during follow-up. The main research questions of interest in LS-SCLC were 1) integratingnovel targeted therapies-immunotherapies (n=160, 81%), 2) PCI (+/- hippocampal sparing) vs. MRIsurveillance (n=140, 71%) and, 3) biomarker driven trials (n=92, 46%).Conclusion: Once daily radiotherapy (60–66 Gy in 30–33 fractions) remains the most prescribed radiotherapyfractionation, despite the findings suggested by the CONVERT trial.info:eu-repo/semantics/publishe

Ecofriendly recycled aggregate concrete and bioreceptivity

Nowadays, it becomes essential to limit environmental impact of building materials and to consider the life cycle of materials used. Recycling of materials from demolition has the dual objective of preserving natural resources and limiting the number of storage sites. The study presented here aims to develop the use of recycled aggregate issued of concrete in total replacement of natural materials (sand and gravel). This work has to be done upstream the studies on bio-corrosion or bio-receptivity of these concrete composed of recycled aggregates. Following an experimental analysis of physical, mechanical and mineralogical properties of recycled aggregates,the influence of these characteristics on choosing formulation parameters of concrete and mortar was studied. It was shown that the use of superplasticizers is necessary to reach satisfactory properties of concrete. The next step of this work will be toanalyse the bio-receptivity of these concrete and compatibilitywith bio-admixture used to decrease bio-receptivity and bio-corrosion; and to develop bio-superplasticizers to replace chemical ones
