Abstract

A retrospective analysis was done using the Surveillance, Epidemiology, and End-Results (SEER) database to determine the trends in overall survival and identify prognostic factors in patients with mantle cell lymphoma (MCL). In total 5367 cases of MCL identified from 1992 to 2007 were split into three cohorts, group 1(1992-1999), group 2 (2000-2003) and group 3 (2004-2007). Survival was analyzed using the Cox proportional hazards model to correct for age, gender and stage of disease. The proportion of patients with advanced disease at diagnosis, male gender and advanced age increased over time and these were all associated with increased mortality. The overall survival remained unchanged. However, when adjusted for the increased proportion of patients with poor prognostic features noted above, we found a significant improvement in survival. The adjusted model also showed an improvement in predicted survival over time in patients with advanced stage. No change in survival was seen in patients with localized disease. Although this analysis is not designed to evaluate specific treatment modalities, these data suggest that the development of new treatment strategies over the past decade may be impacting the survival of patients with advanced MCL despite the finding that the overall survival remains unchanged in the general US population.
