Rituximab, gemcitabine and oxaliplatin: An effective regimen in patients with refractory and relapsing mantle cell lymphoma

Mantle cell lymphoma constitutes one of the lymphomas with poorest prognosis at relapse with limited effective salvage regimens due to advanced age. We present results of a new salvage regimen, rituximab, gemcitabine and oxaliplatin (GEMOX-R), in 14 patients with relapsing (n = 9) or refractory (n = 5) mantle cell lymphoma. The median number of cycles was 5.5 for a total of 72 cycles evaluated in the current study. The median age was 69.5 years with high-risk features. Patients received a mean number of prior treatment lines of 1.79. Sixty-four percent achieved CR (total response rate of 85%). With a median follow-up of 11 months, OS and PFS were 58% and 45% at 12 months. The major toxicity was thrombopenia grade III-IV (35%). Factors related with overall survival were ECOG performance status and a-IPI at GEMOX-R. We conclude that GEMOX-R displays an outstanding efficacy with an excellent toxicity profile in a pretreated elderly population.
