Facteurs épidémiologiques influençant la survie dans le lymphome à cellules du manteau

subject

description

Mantle Cell Lymphoma (MCL) is a recently defined entity, typically characterised by the genetic translocation t(11 ;14)(q13 ;q32) and counting for 2 - 10% of all non-Hodgkin Lymphomas. With a median survival between 3 and 5 years after diagnosis, MCL is an agressive disease and despite the recent therapeutic advances little in know about its prognostic factors. Some studies had investigated clinicopathological features and new treatment strategies, but there is a lack of knowledge regarding the impact of lifestyle and environnemental factors on outcome of MCL patients. From 2008 to 2012, the LYSA Group conducted in France two prospective multi center clinical trials on MCL : LM manteau 2010 SA "RiBVD" (NCI01457144) and Manteau 2007 SJ "LyMa" (NCT00921414). After a comparison of these patients with population-based data, socioeconomic factors, lifestyle factors and their influence on survival had been investigated through a qualitative survey administrated to each volunteer after diagnosis. Our findings suggest that low educational attainment, low body body mass index and alcohol consumption are associated with a higher risk of death in MCL. However, to investigate lifestyle factors in this rare NHL subtype, larger studies should be carried out. Clinical trial inclusion criteria must be widen to select more patients and patients more representative of general population. Implementation of these epidemiological studies in clinical practice should be considered.
