Survival of bronchopulmonary cancers according to radon exposure

IntroductionResidential exposure is estimated to be responsible for nearly 10% of lung cancers in 2015 in France, making it the second leading cause, after tobacco. The Auvergne-Rhône-Alpes region, in the southwest of France, is particularly affected by this exposure as 30% of the population lives in areas with medium or high radon potential. This study aimed to investigate the impact of radon exposure on the survival of lung cancer patients.MethodsIn this single-center study, patients with a histologically confirmed diagnosis of lung cancer, and newly managed, were prospectively included between 2014 and 2020. Univariate and multivariate survival analyses were carried out using a non-proportional risk survival model to consider variations in risk over time.ResultsA total of 1,477 patients were included in the analysis. In the multivariate analysis and after adjustment for covariates, radon exposure was not statistically associated with survival of bronchopulmonary cancers (HR = 0.82 [0.54–1.23], HR = 0.92 [0.72–1.18], HR = 0.95 [0.76–1.19] at 1, 3, and 5 years, respectively, for patients residing in category 2 municipalities; HR = 0.87 [0.66–1.16], HR = 0.92 [0.76–1.10], and HR = 0.89 [0.75–1.06] at 1, 3, and 5 years, respectively, for patients residing in category 3 municipalities).DiscussionAlthough radon exposure is known to increase the risk of lung cancer, in the present study, no significant association was found between radon exposure and survival of bronchopulmonary cancers

Frequency of Asbestos Exposure and Histological Subtype of Ovarian Carcinoma

The International Agency for Research on Cancer established a causal link between asbestos exposure and ovarian cancer. However, the exposure frequency and histological characteristics of asbestos-associated ovarian cancers remain to be investigated in detail. This multicenter case–case study assessed the asbestos exposure in ovarian carcinoma (OC) patients, alongside its association with histological subtype. Women were recruited in four hospitals in Lyon, France. Histological reports were reviewed by a pathologist. Patient and family members’ data were collected by phone-based questionnaires. Asbestos exposure was defined as direct (occupational and environmental) and indirect (via parents, partners, and children). An industrial hygienist assessed the probability and level of exposure. The 254 enrolled patients (mean age 60 years) reported having an average of 2.3 different jobs (mean working duration 29 years). The prevalence of direct and indirect asbestos exposure was 13% (mean exposure duration 11 years) and 46%, respectively. High-grade serous carcinoma accounted for 73% of all OCs and 82% of histological subtypes in women with direct exposure. After adjustment on a familial history of OC, no significant associations between asbestos exposure (direct and/or indirect) and high-grade serous carcinoma were found. Women with OC had a high prevalence of asbestos exposure. Establishing risk profiles, as reported here, is important in facilitating compensation for asbestos-related OCs and for the surveillance of women at risk

Systematic Screening for Occupational Exposures in Lung Cancer Patients: A Prospective French Cohort

Occupational lung cancers are under-reported and under-compensated worldwide. We assessed systematic screening for occupational exposure to carcinogens combining a self-administered questionnaire and an occupational consultation to improve the detection of occupational lung cancers and their compensation. Social deprivation and the costs of this investigation were estimated. Patients with lung cancer received a self-administered questionnaire to collect their job history, potential exposure to carcinogens and deprivation. A physician assessed the questionnaire and recommended an occupational consultation if necessary. During the consultation, a physician assessed if the lung cancer was work-related and, if it was, delivered a medical certificate to claim for compensation. Over 18 months, 440 patients received the self-administered questionnaire: 234 returned a completed questionnaire and a consultation was required for 120 patients. Compensation was judged possible for 41 patients. Among the 35 medical certificates delivered, 19 patients received compensation. Nearly half the patients (46%) were assessed as socially deprived and these patients took significantly longer to return the questionnaire compared with those who were not deprived. The mean cost of the process was €62.65 per patient. Our results showed a systematic self-administered questionnaire can be used to identify patients potentially exposed to carcinogens and to improve compensation

Évaluation d’un auto-questionnaire de repérage des expositions professionnelles chez les patients atteints de cancer bronchopulmonaire

International audienceTen to 29% of lung cancers might be linked to occupational factors but 60% of them are not compensated. The PROPOUMON project aimed to improve the identification, recognition and compensation of occupational lung cancer as occupational disease using a self-administered questionnaire (AQREP). One objective was to assess the AQREP, comparing it with the questionnaire drawn up by the French Language Pneumology Society (Q-SPLF). From March 2014 to September 2015, 90 lung cancer patients treated at the Centre Léon-Bérard responded to the AQREP and Q-SPLF. The two physicians in charge of the consultation assessed independently whether or not a consultation was indicated. A certificate for the compensation process was proposed when a suspicion of high or average imputability was identified. Analysis of the questionnaires was concordant for 73% of the patients. The AQREP has a sensitivity of 72% and a specificity of 73%. Its positive and negative predictive values were 62 and 82%. The information provided by 24 patients were discordant between questionnaires. In two patients with discordant evaluation (AQREP+/Q-SPLF-; AQREP-/Q-SPLF+), one Initial Medical Certificate (IMC) was written. This study made it possible to conclude that AQREP is relevant for the identification of potentially occupational lung cancers. Collegial discussion of complex cases might be considered. The project is currently been extended to other centers and to lymphoma.Dix à 29 % des cancers bronchopulmonaires seraient d’origine professionnelle dont 60 % ne seraient pas indemnisés.

Les deux médecins responsables de la consultation évaluaient de façon indépendante, sur la base de l’AQREP ou du Q-SPLF, l’indication d’une consultation. Si à l’issue de la consultation des arguments en faveur d’une origine professionnelle étaient réunis, une démarche de déclaration était proposée. L’analyse des questionnaires par les médecins était concordante à 73 %. L’AQREP a une sensibilité de 72 % et une spécificité de 73 %. Ses valeurs prédictives positive et négative sont de 62 et 82 %. Les informations renseignées par 24 patients étaient discordantes entre les questionnaires. Pour deux patients ayant une évaluation discordante (AQREP+/Q-SPLF- ; AQREP-/Q-SPLF+), un « Certificat médical initial » a été rédigé. Le premier a été refusé par l’Assurance maladie, le second est en cours d’instruction. Cette étude a permis de conclure en la capacité de l’AQREP à repérer les cancers bronchopulmonaires potentiellement d’origine professionnelle. Une réunion de concertation pour discuter des cas complexes pourrait être envisagée. Le projet s’élargit actuellement à d’autres centres et aux lymphomes

Connected device and therapeutic patient education to promote physical activity among women with localised breast cancer (DISCO trial): protocol for a multicentre 2×2 factorial randomised controlled trial

International audienceIntroduction: Despite safety and benefits of physical activity during treatment of localised breast cancer, successful exercise strategies remain to be determined. The primary objective of the 'dispositif connecté', that is, connected device in English trial is to evaluate the efficacy of two 6-month exercise interventions, either single or combined, concomitant to adjuvant treatments, on the physical activity level of patients with breast cancer, compared with usual care: an exercise programme using a connected device (activity tracker, smartphone application, website) and a therapeutic patient education intervention. Secondary objectives are to evaluate adherence to interventions, their impact at 6 and 12 months, representations and acceptability of interventions, and to assess the cost-effectiveness of the interventions using quality-adjusted life-years.Methods and analysis: This is a 2×2 factorial, multicentre, phase III randomised controlled trial. The study population (with written informed consent) will consist of 432 women diagnosed with primary localised invasive breast carcinoma and eligible for adjuvant chemotherapy, hormonotherapy and/or radiotherapy. They will be randomly allocated between one of four arms: (1) web-based connected device (evolving target number of daily steps and an individualised, semisupervised, adaptive programme of two walking and one muscle strengthening sessions per week in autonomy), (2) therapeutic patient education (one educational diagnosis, two collective educational sessions, one evaluation), (3) combination of both interventions and (4) control. All participants will receive the international physical activity recommendations. Assessments (baseline, 6 and 12 months) will include physical fitness tests, anthropometrics measures, body composition (CT scan, bioelectrical impedance), self-administered questionnaires (physical activity profile (Recent Physical Activity Questionnaire), quality of life (European Organization for Research and Treatment of Cancer Quality-Of-Life Questionnaire-30, EQ-5D-5L), fatigue (Piper Fatigue Scale-12), social deprivation (Evaluation of Deprivation and Inequalities in Health Examination Centres), lifestyle, physical activity barriers, occupational status) and biological parameters (blood draw).Ethics and dissemination: This study was reviewed and approved by the French Ethics Committee. The findings will be disseminated to the scientific and medical community via publications in peer-reviewed journals and conference presentations.Trial registration number: NCT03529383; Pre-results

Domestic use of pesticides during early periods of development and risk of testicular germ cell tumors in adulthood: a French nationwide case-control study

International audienceBackground - Testicular germ cell tumours (TGCT) are the most frequent cancers in young men in developed countries and their incidence rate has doubled worldwide over the past 40 years. Early life exposures to pesticides are suspected to increase TGCT risk. Our research aimed at estimating adult TGCT risk associated with parental domestic use of pesticides during early periods of child development. Methods - We conducted a case-control study of 304 TGCT cases, aged 18-45 years old, recruited in 20 French university hospitals, and 274 controls frequency-matched on hospital and birth year. Participants' mothers provided information on their domestic use of pesticides from 1 year before start of pregnancy to 1 year after their son's birth, for gardening activities, treatment of indoor plants, pets, wood and mold, and pest control. Odds ratios (OR) for TGCT (overall and by histological subtype) and 95% confidence intervals (CI) were estimated using conditional logistic regression. Results - Prevalence of reported domestic use of pesticides was 77.3% for insecticides, 15.9% for fungicides and 12.1% for herbicides. While no association was found for any use of insecticides (OR = 1.27, CI = 0.80-2.01) or herbicides (OR = 1.15, CI = 0.67-2.00), elevated risks of TGCT overall (OR = 1.73, CI = 1.04-2.87) and non-seminoma subtype (OR = 2.44, CI = 1.26-4.74) were observed for any use of fungicides. When specific purposes were examined, using fungicides and/or insecticides for woodwork (OR = 2.35, CI = 1.06-5.20) and using insecticides on cats and dogs (OR = 1.95, CI = 1.12-3.40) were associated with increased risk of non-seminoma subtype. We found no association for seminoma subtype. Conclusions - Although recall bias may partially explain the elevated ORs, our study provides some evidence of a positive association between domestic use of pesticides during early periods of development, particularly fungicides and risk of adult TGCT and non-seminoma. Given the common domestic use of pesticides in France, further research on TGCT risk is warranted
