Abstract

BACKGROUND:

Patients with relapsed diffuse large B-cell lymphoma (DLBCL) have a poor prognosis. Gemcitabine, methylprednisolone, cisplatin +/- rituximab (GEM-P+/-R) is a salvage regimen with limited overlap in toxicity with first-line therapy and short duration of inpatient delivery.

METHODS:

We assessed the efficacy and safety of GEM-P+/-R in a retrospective single-centre analysis including patients meeting criteria of ≥ 18 yr of age, histologically proven DLBCL, treated between 2001 and 2011 in second-line with gemcitabine 1000 mg/m(2) day 1, 8 and 15, methylprednisolone 1000 mg day 1-5, cisplatin 100 mg/m(2) day 15 (replaced with carboplatin AUC5 if contraindication/toxicity) +/- rituximab 375 mg/m(2) day 1 and 15, every 28 d.

RESULTS:

Forty-five patients aged 25-74 received a median of three cycles of GEM-P+/-R; 64% received rituximab. In 44 evaluable patients receiving GEM-P+/-R, overall response rate (ORR) was 48%; in 28 evaluable patients treated with rituximab + GEM-P (R-GEM-P), ORR was 61%. With median follow-up of 50.5 months (95% CI: 28.3-72.7), 3-yr overall survival (OS) from start of GEM-P+/-R was 31.4% (95% CI: 16.5-46.3); in patients treated with R-GEM-P, 3-yr OS was 49.1% (95% CI: 28.7-69.5). Predominant grade ≥ 3 toxicities were haematological; thrombocytopenia 69%, neutropenia 60% and febrile neutropenia 7%.

CONCLUSION:

R-GEM-P is a deliverable regimen with useful activity in second-line treatment of DLBCL. Our data suggest that rituximab should be given concurrently.
