Study Overview
Brief Summary
Diffuse large B cell lymphoma (DLBCL) is the most common non-Hodgkin's lymphoma, accounting for between 30% and 50% of the patients. Although it is considered a curable disease, still at least 40 % of the patients will fail first line chemotherapy. The International Prognostic Index (IPI) score and the age adjusted IPI (aIPI) has been used since they were published to identify patients with different outcome.
There is not standard therapy for young patients with DLBCL and unfavourable IPI score. The survival of these patients remains poor, with EFS around 40%.
The combination of RCHOP with new drugs is an attractive approach to treat these patients.
The goal is to evaluate the proportion of patients with Event-Free Survival (EFS) after 2 years, with a diagnosis of DLBCL with an aIPI > 1 or an aIPI =1 with increased levels of beta-2-microglobulin (above the Upper Limits of Normal.)
Detailed Description
Diffuse large B cell lymphoma (DLBCL) is the most common non-Hodgkin's lymphoma, accounting for between 30% and 50% of the patients. Although it is considered a curable disease, still at least 40 % of the patients will fail first line chemotherapy. The International Prognostic Index (IPI) score and the age adjusted IPI (aIPI) has been used since they were published to identify patients with different outcome.
CHOP chemotherapy administered every 21 days has been for years the standard therapy for advanced DLBCL achieving a long term overall survival (OS) of about 40%. Many studies show that the addition of the monoclonal antibody Rituximab improves the patients survival achieving higher rates of event-free survival in elderly patients with both,favourable and unfavourable IPI score. R-CHOP also improved survival in young patients with favourable IPI score.
There is not standard therapy for young patients with DLBCL and unfavourable IPI score. The survival of these patients remains poor, with EFS around 40%.
The combination of RCHOP with new drugs is an attractive approach to treat these patients.
The investigators propose a phase II randomized clinical trial for young patients with unfavourable IPI score DLBCL using 6 cycles of the combination of subcutaneous Bortezomib with R-CAP (RCHOP without vincristine, to avoid neuropathy) comparing with the standard immunochemotherapy regimen R- CHOP every 21 days.
