Background Since 2010, nationwide networks of reference centers for sarcomas (RREPS/NETSARC/RESOS) collected and prospectively reviewed all cases connective tumors intermediate malignancy (TIM) in France. Methods The incidence sarcoma or TIM (2013–2016) was measured using the 2013 WHO classification confirmed by a second independent review expert pathologists. Simple clinical characteristics, yearly variations correlation with published trials are presented analyzed. Results Over 150...

Abstract Background Spatial inequalities in health result from different exposures to risk factors according the features of geographical contexts, terms physical environment, social deprivation, and care accessibility. Using a common referential, which combines indices measuring these contextual features, could improve comparability studies understanding spatial dimension inequalities. Methods We developed Geographical Classification for Health (GeoClasH) distinguish French municipalities...

Investigation of the disparities in access to experimental treatment early-phase clinical trials is lacking. The objective EGALICAN-2 study was identify factors underpinning such inequalities.A national prospective survey conducted 11 trial centers (CLIP2) certified by French National Cancer Institute. Sociodemographic, socioeconomic and medical data were collected. Univariate logistic regression models carried out estimate odds ratios 90% confidence intervals associated with effect each...

Spatial inequalities in cancer management have been evidenced by studies reporting lower quality of care or/and survival for patients living remote or socially deprived areas. NETSARC+ is a national reference network implemented to improve the outcome sarcoma France since 2010, providing access specialized diagnosis and Multidisciplinary Tumour Board (MTB). The IGéAS research program aims assess potential this innovative organization, with cancers including rare tumours, go through...

Rare cancer patients face lower survival and experience delays in diagnosis therapeutic mismanagement. Considering the specificities of rare cancers, referral networks have been implemented France to improve management patients. The IGéAS research program aims assess networks’ ability reduce inequalities. Data analysis cohort (n = 20,590, sarcoma diagnosed between 2011 2014) by gathering medical data geographical index will identify risk factors associated with belated access expertise or no...

Abstract This article provides a critical and genealogical analysis of the allostatic load research framework. AL is used as case study to analyse how current biosocial context articulated in field health inequalities research. Providing contemporary studies with genealogy concept, we show that ambition use biological tools improve measurements, predictions, ultimately public action, rooted history predates entanglements. We conceptual methodological grounding relation ambitious propositions...

Dans un contexte post-génomique, le concept d’exposome a été introduit par Christopher Wild pour proposer une approche unifiée des expositions et fédérer différents champs disciplinaires de la recherche en santé environnement. L’approche « exposomique » se caractérise volonté développer analyse à fois intégrative, longitudinale plus précise expositions, cela principalement grâce l’identification biomarqueurs. L’usage du d’exposome, qui révèle particulièrement plastique, constitue terrain...

Aim: We performed a clinical audit of the management patients with EGFR mutations, 1 year after introduction tyrosine kinase inhibitor (EGFR-TKI) in first-line treatment. Methods: Compliance was defined by tumor molecular profiling for stage IIIB and IV non-small-cell lung cancer treatment as recommended French guidelines. Results: Among 169 EGFR-mutated patients, compliance 76.4%. The most common noncompliance criterion chemotherapy given instead EGFR-TKI. No dedicated multidisciplinary...

Agir efficacement contre les inégalités géographiques face aux cancers implique une meilleure compréhension du processus aboutissant à ces inégalités. Une méthodologie interdisciplinaire, traitant conjointement multiples dimensions par lesquelles le territoire impacte la santé et retraçant l'évolution pronostique des patients, permettrait de répondre ce besoin. La cohorte EMS, prise en charge patients atteints sarcomes (cancers rares) Rhône-Alpes, a été analysée suivant principes...
