Aim: Toxicity and efficacy assessment of the R-EPOCH/R-GIDIOX and R-EPOCH/R-HMA schemes in primary MCL patients eligible for autoSCT.

Methods: On May 2008 18 untreated MCL patients, average 55 years (29–63) were enrolled. After the first R-EPOCH cycle, patients were stratified according to the toxicity they had received, with either R-EPOCH/R-HD-Met-Ara-C (Romanguera J. 2005) or R-EPOCH/R-GIDIOX (gemcitabine 800 mg/m2 days 1 and 4, oxaliplatin 120 mg/m2 day 2, irinotecan 100 mg/m2 day 3, dexamethasone 10 mg/m2 IV days 1-5, ifosfamide 1000 mg/m2 days 1–5) for those who received higher hematological toxicity (grade 4 for more than 3 days) being administered. Depending on the terms of response, the patients received 6–8 cycles of chemotherapy and autoSCT (BEAM-R). Rituximab maintenance was performed every three months for 2 years.

Results: Thirty-three GIDIOX cycles were analyzed, with evidence that GIDIOX is a less intensive and toxic regimen than HMA, but in our selection the hematologic toxicity in the R-GIDIOX and R-HMA arms were similar due to less patients fitting into the R-GIDIOX arm. The main non-hematological toxicity of GIDIOX was hepatic, with elevated aminotransferases grades 1–2 and 3 in 55% and 2% of cycles respectively, without clinical signs. The sources of the stem cells were PB in 16 patients and BM in one case. Eight patients achieved CR (MRD-) from 9 in the HMA arm, with 1 induction death after the first HMA cycle (acute renal failure and septic shock), and one relapse 8 months after autoSCT, with observation from 4 to 17 months. The GIDIOX arm included 9 patients: OR 100%, 7 CR, 2 PR, with observation from 3 to 27 months, without relapses.

Conclusion: The GIDIOX scheme is less toxic than HMA and equally effective in response induction and mobilization, so it could be recommended for those in whom high-dose AraC and methotrexate can potentially cause severe adverse consequences.
