Body mass index at diagnosis is associated with survival outcome in peripheral T-cell lymphoma: a study of Chinese population

Abstract Objective Obesity increases the risk for many diseases, including some malignancies. We found that in diffuse large B-cell lymphoma, the most common form of non-Hodgkin’s lymphoma, patients with higher body mass index had significantly longer overall survival. Patients with peripheral T-cell lymphoma usually have worse outcomes than those with diffuse large B-cell lymphoma. Nonetheless, the association between body mass index at diagnosis and survival in patients with peripheral T-cell lymphoma remains unclear. Methods This retrospective study included 411 peripheral T-cell lymphoma patients from January 2010 to July 2017. Patients were stratified by body mass index into low body mass index (
