RESUMO
OBJECTIVES: Etiological factors of testicular germ cell tumors (TGCT) remain largely unknown, but a causal role of occupational exposures to solvents has been suggested. Previous studies analyzing these exposures reported discordant results, potentially related to exposure assessment methods. The aim of this study was to investigate the role of occupational exposure to solvents on the risk of developing TGCT among young men. METHODS: This study examined occupational exposures to solvents and TGCT risk based on the lifetime work histories of 454 cases and 670 controls, aged 18-45 years, of the French national TESTIS case-control study. Solvent exposure was estimated using: (i) exposure assignment by job-exposure matrix (JEM) and (ii) JEM combined with self-reported exposure data from specific questionnaires (SQ) and expert assessment (EA). Odds ratios (OR) and 95% confidence intervals (CI) were estimated using conditional logistic regression models. RESULTS: Both approaches (JEM and JEM+SQ+EA) showed a consistent association between TGCT and trichloroethylene exposure (exposed versus not exposed; JEM=OR 1.80 [95% confidence interval (CI) 1.12-2.90] and JEM+SQ+EA= OR 2.59 (95% CI 1.42-4.72). Both approaches also observed positive associations with ketone esters and fuels & petroleum-based solvents. CONCLUSION: The results suggest that some organic solvents might be involved in the pathogenesis of TGCT among occupationally exposed men. The combined use of JEM+SQ+EA seemed to limit misclassification by considering individual exposure variability and is, therefore, an appealing approach to assess occupational exposures in epidemiological studies.

This article describes some of the key prevention services in the Leon Berard Comprehensive Cancer Center (CLB) Lyon, France, which are based on clinical prevention services, outreach activities, and collaboration with professional and territorial health communities. In addition, research is embedded at all stages of the prevention continuum, from understanding cancer causes through to the implementation of prevention interventions during and after cancer. Health promotion activities in the community and dedicated outpatient primary cancer prevention services for individuals at increased risk have been implemented. The CLB's experience illustrates how prevention can be integrated into the comprehensive mission of cancer centers, and how in turn, the cancer centers may contribute to bridging the current fragmentation between cancer care and the different components of primary, secondary, and tertiary prevention. With increasing cancer incidence, the shift toward integrated prevention-centered cancer care is not only key for improving population health, but this may also provide a response to the shortage of hospital staff and overcrowding in cancer services, as well as offer opportunities to reduce carbon emissions from cancer care.

Background: Testicular germ cell tumors (TGCT) are the most frequent cancer in young men in developed countries. Parental occupational exposures during early-life periods are suspected to increase TGCT risk. The objective was to estimate the association between parental occupations at birth and adult TGCT. Methods: A case-control study was conducted, including 454 TGCT cases aged 18-45 from 20 French university hospitals, matched to 670 controls based on region and year of birth. Data collected from participants included parental jobs at birth coded according to the International Standard Classification of Occupation-1968 and the French nomenclature of activities-1999. Odds ratios (OR) for TGCT and 95% confidence intervals (CI) were estimated using conditional logistic regression, adjusting for TGCT risk factors. Results: Paternal jobs at birth as service workers (OR = 1.98, CI 1.18-3.30), protective service workers (OR = 2.40, CI 1.20-4.81), transport equipment operators (OR = 1.96, CI 1.14-3.37), specialized farmers (OR = 2.66, CI 1.03-6.90), and maternal jobs as secondary education teachers (OR = 2.27, CI 1.09-4.76) or in secondary education (OR = 2.35, CI 1.13-4.88) were significantly associated with adult TGCT. The risk of seminoma was increased for the above-mentioned paternal jobs and that of non-seminomas for public administration and defence; compulsory social security (OR = 1.99, CI 1.09-3.65); general, economic, and social administration (OR = 3.21, CI 1.23-8.39) for fathers; and secondary education teacher (OR = 4.67, CI 1.87-11.67) and secondary education (OR = 3.50, CI 1.36-9.01) for mothers. Conclusion: Some paternal jobs, such as service workers, transport equipment operators, or specialized farmers, and maternal jobs in secondary education seem to be associated with an increased risk of TGCT with specific features depending on the histological type. These data allow hypotheses to be put forward for further studies as to the involvement of occupational exposures in the risk of developing TGCT, such as exposure to pesticides, solvents, or heavy metals.

BACKGROUND: Spatial inequalities in health result from different exposures to health risk factors according to the features of geographical contexts, in terms of physical environment, social deprivation, and health care accessibility. Using a common geographical referential, which combines indices measuring these contextual features, could improve the comparability of studies and the understanding of the spatial dimension of health inequalities. METHODS: We developed the Geographical Classification for Health studies (GeoClasH) to distinguish French municipalities according to their ability to influence health outcomes. Ten contextual scores measuring physical and social environment as well as spatial accessibility of health care have been computed and combined to classify French municipalities through a K-means clustering. Age-standardized mortality rates according to the clusters of this classification have been calculated to assess its effectiveness. RESULTS: Significant lower mortality rates compared to the mainland France population were found in the Wealthy Metropolitan Areas (SMR = 0.868, 95% CI 0.863-0.873) and in the Residential Outskirts (SMR = 0.971, 95% CI 0.964-0.978), while significant excess mortality were found for Precarious Population Districts (SMR = 1.037, 95% CI 1.035-1.039), Agricultural and Industrial Plains (SMR = 1.066, 95% CI 1.063-1.070) and Rural Margins (SMR = 1.042, 95% CI 1.037-1.047). CONCLUSIONS: Our results evidence the comprehensive contribution of the geographical context in the constitution of health inequalities. To our knowledge, GeoClasH is the first nationwide classification that combines social, environmental and health care access scores at the municipality scale. It can therefore be used as a proxy to assess the geographical context of the individuals in public health studies.

INTRODUCTION: Since the life expectancy of women with breast cancer has increased, tertiary prevention, through the Therapeutic Patient Education (TPE), is now a part of patient support. The main objective of this pilot study is to evaluate the cost of a nutrition and physical activity TPE program intended to help women with breast cancer in the management of their weight. METHODS: This study is a description of costs, based on the micro-costing method, of the first two years of the program, conducted on an outpatient basis, at the Cancer Center Leon Berard, Lyon, France, with the involvement of a dietician and a physical activity trainer. Only the direct costs were taken into account, from the hospital's perspective, in Euro 2016. Sensitivity analyses were also conducted. RESULTS: Sixty-five patients were included in the study in 2014/2015. Their mean age was 52 years, the majority of them were in sick leave (65 %). In most cases, they had undergone surgery (95 %) and chemotherapy (71 %). The average cost per patient of the program was 541.04 (SD 88.44; 95 % IC [520.06-562.03]) excluding overhead costs, i.e. 687.13 overhead costs included. The unit cost of the dietician was the most sensitive parameters. CONCLUSION: This cost study, an accurate estimate of the production costs, allows to inform the decision-maker in term of pricing of such a program and to make the necessary adjustments in order to optimize the organization of this activity.

OBJECTIVE: To assess the quality of recommendations from 161 clinical practice guidelines (CPGs) using AGREE-REX-D (Appraisal of Guidelines REsearch and Evaluation-Recommendations Excellence Draft). DESIGN: Cross-sectional study SETTING: International CPG community. PARTICIPANTS: Three hundred twenty-two international CPG developers, users, and researchers. INTERVENTION: Participants were assigned to appraise one of 161 CPGs selected for the study using the AGREE-REX-D tool MAIN OUTCOME MEASURES: AGREE-REX-D scores of 161 CPGs (7-point scale, maximum 7). RESULTS: Recommendations from 161 CPGs were appraised by 322 participants using the AGREE-REX-D. CPGs were developed by 67 different organizations. The total overall average score of the CPG recommendations was 4.23 (standard deviation (SD) = 1.14). AGREE-REX-D items that scored the highest were (mean; SD): evidence (5.51; 1.14), clinical relevance (5.95; SD 0.8), and patients/population relevance (4.87; SD 1.33), while the lowest scores were observed for the policy values (3.44; SD 1.53), local applicability (3,56; SD 1.47), and resources, tools, and capacity (3.49; SD 1.44) items. CPGs developed by government-supported organizations and developed in the UK and Canada had significantly higher recommendation quality scores with the AGREE-REX-D tool (p < 0.05) than their comparators. CONCLUSIONS: We found that there is significant room for improvement of some CPGs such as the considerations of patient/population values, policy values, local applicability and resources, tools, and capacity. These findings may be considered a baseline upon which to measure future improvements in the quality of CPGs.

As the benefits of physical activity (PA) in oncology field continue to be demonstrated, multiple structures (sports clubs, associations ) develop PA programs and activities to offer cancer patients survivors the opportunity to continue adapted physical activity. Promoted in the 2014-2019 cancer plan as complementary supportive care, the practice of physical activity is legitimized by the 2016 Health Act of the Ministry of Social Affairs and Health, including the amendment 'prescription health sport', by giving it a legislative framework. In this context of development of new PA offers for cancer patients, it seems necessary to determine and evaluate the structures on their capacities to supervise physical activities for this population with specific needs. This article presents the methodological development and validation process of a tool used to characterize the different structures offering physical activity programs for people who have had cancer, and seeks to define the quality criteria that a structure should meet in the current state of knowledge. Ten of these criteria were selected according to a qualitative methodology and the final tool therefore facilitates the identification of quality programs in post-cancer PA, and could be used systematically by both users and professionals as part of the post-cancer care pathway, as well as by the sport-health platforms themselves in the current dynamics of their deployment throughout the national territory.

We undertook a cost-effectiveness analysis (CEA) to compare an exercise and nutritional program with the usual nutritional care concomitant to adjuvant chemotherapy in localized breast cancer patients. The CEA was designed as part of the interventional, controlled, randomized, single-center, open-label PASAPAS study. Breast cancer patients receiving first-line adjuvant chemotherapy at a French Comprehensive Cancer Center were randomized 2:1 to a 6-month exercise program of supervised indoor and outdoor group sessions in addition to usual nutritional care (exercise arm) or a usual nutritional care group receiving dietary and physical activity counseling (control arm). Costs were assessed from the French national insurance perspective (in Euros, 2012). Incremental cost-effectiveness ratios (ICERs) were calculated for four criteria: body mass index, waist circumference, body fat percentage, and estimated aerobic capacity. Uncertainty around the ICERs was captured by a probabilistic analysis using a non-parametric bootstrap method. The analysis was based on 60 patients enrolled between 2011 and 2013. Average intervention costs per participant were 412 in the exercise arm (n = 41) and 117 (n = 19) in the control arm. Total mean costs were 17,344 (standard deviation 9,928) and 20,615 (standard deviation 14,904), respectively, did not differ significantly (p = 0.51). The 6-month exercise program was deemed to be cost-effective compared with usual care for the estimated aerobic capacity. Multicenter randomized studies with long-term costs and outcomes should be done to provide additional evidence. Clinical trial: The PASAPAS study is registered under ClinicalTrials.gov. Trial registration ID: NCT01331772.

Background: Our study examined the social disparities that exist in the implementation of protection measures for occupational exposure to carcinogenic, mutagenic and reprotoxic agents in France, and its aim was to identify which types of employees/jobs require priority action. Methods: We analyzed data from the 2010 French national cross-sectional survey of occupational hazards. The availability of the various collective and individual protections was explored. The associations of job and company characteristics with protective measures were studied by multilevel regressions. Results: Effective collective protection measures were implemented in 25% of the exposure situations. Managers and intellectual professionals, who accumulated lower CMR exposure prevalences, durations, and intensities than blue-collar workers, benefited the most from effective collective protections. The availability of effective collective protection measures was not influenced by the size of the company. The presence of a Committee for health, safety, and work conditions, as well as intervention of occupational health and safety officers in the past 12 months were associated with a lower exposure intensity, but not with the implementation of more protection measures. Longer exposure durations were associated with more effective collective protection. Conclusion: Substantial discrepancies were observed in exposure levels and protection measures as a function of the characteristics of employees' jobs and the companies that they work for. The main priority in regard to prevention should be a focus on unskilled workers, since their collective protection still appears to be insufficient, while their exposure lengths and intensities were the most substantial.

Return to work (RTW) is an important step for breast cancer survivors (BCSs). However, they face many barriers that affect particularly women with low socioeconomic status (SES). Health care, workplace, and insurance actors lack knowledge and collaborate poorly. No intervention to date has proven effective to reduce social disparities in employment after breast cancer. The intervention mapping (IM) protocol is being used in France to develop, implement, and evaluate an intervention to facilitate and sustain RTW after breast cancer [FAciliter et Soutenir le retour au TRAvail après un Cancer du Sein (FASTRACS) project]. The research question of this study was to elicit the needs for RTW after breast cancer from various stakeholders' point of view. The aim of this study was to describe the process and the preliminary results of the needs assessment of the FASTRACS project. Different methods were followed to (a) establish and work with a planning group and (b) conduct a needs assessment to create a logic model of the problem. A planning group was organized to gather the stakeholders with the research team. A review of the literature and indicators was conducted to identify the magnitude of the problem and the factors influencing RTW. A qualitative inquiry was conducted with 12 focus groups and 48 individual semi-structured interviews to explore the needs and experience of the stakeholders. The results of these tasks were the proposition of a charter of partnership to structure the participative process, a review of the scientific evidence and indicators, and the description by the stakeholders of their needs and experience. Many stakeholders disagreed with the concept of "early intervention." They advocated for a better support of BCSs during their RTW, emphasized as a process. Anticipation, intersectoral collaboration, and workplace accommodation were mentioned to fit the needs of the BCS and their environment. A logic model of the problem was elaborated from these data. The ability of the model to consider specific characteristics of women with low SES is discussed, with a view to developing the FASTRACS intervention through the next steps of the IM protocol.
RESUMO
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.

PURPOSE: The proportion of lung cancers with an occupational origin has been estimated to be between 10 and 20%. They are largely under-reported, as 60% are not compensated as occupational disease. Although most patients are not familiar with the process of compensation, other factors could explain this under-reporting. The aim of this study was to identify psychosocial factors that could impact patients with occupational lung cancer to claim for compensation. METHODS: We conducted a case study involving semi-structured interviews with eight lung cancer patients enrolled in a cohort designed to systematically screen occupational exposures and propose claims for compensation to work-related cancer patients. RESULTS: Seven interviewed patients were familiar with occupational cancers, but most of them did not believe that past exposure could be related to their current disease. Patients associated compensation claims with a long and complex procedure for an abstract purpose. Several patients expressed a certain attachment to their employers. CONCLUSION: Interviewed patients often considered compensation claims to be a grievance procedure against the employers whom they did not consider to be responsible for their disease. Lung cancer is itself an obstacle to compensation considering the aggressive treatments and related adverse events, the poor medium-term prognosis and the predominant role of smoking in the etiology of the disease. Patients mentioned the financial compensation and the role of healthcare professionals as key elements to motivate them to claim for compensation.

Ten 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.

Background: To explore trends in social and occupational inequalities in terms of exposure to carcinogenic, mutagenic and reprotoxic chemicals (CMR) for French employees. Our study assessed data from the French national cross-sectional survey of occupational hazards (SUMER) that was conducted in 2003 and 2010. We included all of the 27 CMR agents that were classified by the International Agency for Research on Cancer or European Union regulations as being known or presumed to have CMR potential in humans. Trends in prevalence and degree of exposure were examined using multilevel logistic regression analysis. The number of employees exposed to CMR agents decreased by 17.5% between 2003 and 2010. The only CMR entities for which exposure rates increased are not considered to be proven CMRs according to the European Union regulations. With the exception of apprentices, there was an overall decrease in exposure prevalence for all employees. This decrease occurred, however, to different extents. The decrease in the risk of exposure to CMR agents was much greater for those on permanent contracts, managers, and in enterprises with more than 500 employees. Nonetheless, in situations where there was potential for exposure, companies with fewer than 10 employees were in fact able to decrease the degree of risk more than the others. Our results confirm the relevance of reinforcing regulatory restrictions for CMR products, while also indicating that monitoring of trends in disparities will allow public health policy makers to better evaluate progress made toward reducing disparities that affect vulnerable populations.

BACKGROUND: Environmental exposure assessment based on Geographic Information Systems (GIS) and study participants' residential proximity to environmental exposure sources relies on the positional accuracy of subjects' residences to avoid misclassification bias. Our study compared the positional accuracy of two automatic geocoding methods to a manual reference method. METHODS: We geocoded 4,247 address records representing the residential history (1990-2008) of 1,685 women from the French national E3N cohort living in the Rhône-Alpes region. We compared two automatic geocoding methods, a free-online geocoding service (method A) and an in-house geocoder (method B), to a reference layer created by manually relocating addresses from method A (method R). For each automatic geocoding method, positional accuracy levels were compared according to the urban/rural status of addresses and time-periods (1990-2000, 2001-2008), using Chi Square tests. Kappa statistics were performed to assess agreement of positional accuracy of both methods A and B with the reference method, overall, by time-periods and by urban/rural status of addresses. RESULTS: Respectively 81.4% and 84.4% of addresses were geocoded to the exact address (65.1% and 61.4%) or to the street segment (16.3% and 23.0%) with methods A and B. In the reference layer, geocoding accuracy was higher in urban areas compared to rural areas (74.4% vs. 10.5% addresses geocoded to the address or interpolated address level, p < 0.0001); no difference was observed according to the period of residence. Compared to the reference method, median positional errors were 0.0 m (IQR = 0.0-37.2 m) and 26.5 m (8.0-134.8 m), with positional errors <100 m for 82.5% and 71.3% of addresses, for method A and method B respectively. Positional agreement of method A and method B with method R was 'substantial' for both methods, with kappa coefficients of 0.60 and 0.61 for methods A and B, respectively. CONCLUSION: Our study demonstrates the feasibility of geocoding residential addresses in epidemiological studies not initially recorded for environmental exposure assessment, for both recent addresses and residence locations more than 20 years ago. Accuracy of the two automatic geocoding methods was comparable. The in-house method (B) allowed a better control of the geocoding process and was less time consuming.

PURPOSE: To explore varied exposure to carcinogenic, mutagenic, and reprotoxic chemicals (CMR) for French employees. METHODS: Our study assessed data from the French national cross-sectional survey of occupational risks (SUMER) that was conducted in 2010 in a national representative sample of employees. We selected 28 CMR agents that were classified by the International Agency for Research on Cancer or European Union as being known or presumed to have CMR potential in humans. The association of individual and job characteristics with exposure prevalence, duration, and intensity of the CMR agents during a 1-week period was examined using multilevel logistic regression analysis. RESULTS: Overall, 10.4% of employees in 2010 were exposed to one or more CMR agents at their workplace, and 3.4% were subjected to multiple CMR exposures. Blue-collar workers, night-shift workers and workers with short-term employment contracts experienced higher exposure prevalence (p < 0.01) and intensity (p < 0.05). Blue-collar workers and shift workers experienced also longer exposure duration (p < 0.001). Conversely, managers, workers of large companies, and women were less exposed to CMR agents (p < 0.001). The presence of a Committee for Health, Safety, and Working Conditions, and intervention by Occupational Health and Safety officers were significantly associated with reduced exposure intensities (p < 0.001 and p < 0.05). Establishment of European CMR regulations and the existence of an applicable substitution principle reduced the exposure duration (p < 0.001) and intensity (p < 0.05). CONCLUSIONS: Our results point out disparities in CMR exposure and identify high-priority targets for prevention measures to help reducing social health discrepancies.

CONTEXT: Survival of children, adolescents and young adults treated for cancer increased with improved treatments. But there is still an increased risk of second primary cancer (SPC) in the long term compared to the population of the same age, especially related to treatments. A reflection on the follow-up of this population and the prevention of SPC is an important issue. OBJECTIVES: To perform a synthesis of the available literature on SCP risk factors, related risk behaviors, occupational exposures and prevention strategies. METHODS: Literature search on PubMed from the following equation: "cancer [Tiab] AND young adult [Tiab] or teen [Tiab] or childhood [Tiab] AND prevention [Tiab] AND survivors [Mesh term]". RESULTS: Twenty-seven articles were included in this synthesis. Children, adolescents and young adults have similar risk behaviors than those of their peers regarding tobacco, diet and sun exposure; however, they have lower physical activity. There are few studies on prevention strategies focused on this population. Results of available studies remain inconclusive. No publication was found in relation to occupational exposure and risk of second cancer. CONCLUSIONS: Children, adolescents and young adults treated for cancer are a population at risk and require long-term follow-up and the implementation of effective prevention strategies tailored to this population.

Despite the rising number of lung cancers recognized as occupational disease, occupational lung cancers are still under-reported. To improve the recognition of occupational lung cancer, we implemented at the Léon-Bérard Cancer Centre, a questionnaire-based process to identify occupational exposures in these patients and improve compensation. Between January 2010 and December 2011, 91 lung cancer patients responded to a questionnaire. An "occupational cancer" consultation was proposed to patients reporting exposure to carcinogens or jobs with risk of exposure. Fifty-one patients were seen in consultation (34 following the questionnaire and 17 directly addressed by the oncologist). A suspicion of high or average imputability was identified in 31 (60.8%) patients and a compensation process seemed possible for 27 (61.4%). Asbestos was the most common carcinogen identified. Among 17 compensation processes engaged, 12 succeeded and one is ongoing. The complexity of the administrative process seems to be an obstacle for patients and perpetuates inequality. The implementation of our approach increased the identification and the compensation of occupational lung cancer. Our approach responds to the objectives of the National Cancer Plan and helps to improve the overall care of patients with cancer. This approach has been awarded by the national label in 2011 "Year of the patients and their rights".

PURPOSE: Early menarche has been associated with a greater risk of several major chronic diseases. Although largely genetically determined, age at menarche also has been related to environmental and lifestyle factors. METHODS: Using linear regression models, we explored simultaneously several pre- and postnatal factors as potential determinants of age at menarche and time to menstrual cycle regularity in 96,493 women participating, since 1990, in the French E3N prospective cohort. RESULTS: Younger age at recruitment, greater father's income index, urban birth place, greater birth length, and larger body silhouette during childhood were associated with an earlier age at menarche (from -1.3 to -4.6 months, P(trend) < .0001) whereas greater family size, food deprivation during childhood, and greater birth weight resulted in a delayed menarche (from +1.5 months to +5.3 months, P(trend) < .0001). Father's income index, urban birth place, and prematurity predicted a shorter time to menstrual cycle regularity (from -1.1 to -1.9 months, P(trend) < .04), whereas birth cohort, larger body silhouette at menarche, and childhood exposure to passive smoking were associated with a longer time to menstrual cycle regularity (from +1.1 months to +8.6 months, P(trend) < .006). CONCLUSIONS: Age at menarche and menstrual cycle regularity are significantly influenced by several individual, environmental and lifestyle factors.
