Platinum-based regimens in relapsed DLBCL

The antitumor effects of cisplatin, carboplatin, and, most recently, oxaliplatin, against B-cell lymphomas have been demonstrated in preclinical and clinical studies. Cisplatin has been extensively studied in combination with high-dose cytarabine- or gemcitabine-based regimens such as, rituximab plus/minus DHAP, ESHAP, or GDP, in patients with refractory/relapsed DLBCL. [119, 111, 115, 117, 118, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129] In addition, carboplatin has been combined with ifosfamide and etoposide (ICE) with or without rituximab.

In general, platinum-based regimens have response rates ranging from 43-82% and CR rates of 16-61%. Successful PBSC mobilization has been documented in the majority of patients eligible for bone marrow transplantation (BMT) treated with such regimens. On the other hand, significant grade 3 and 4 hematological and, to a lesser degree nonhematological, toxicity (grade 1-2) has been observed. Grade 3-4 neutropenia occurs in 50-70% of cases; grade 3-4 thrombocytopenia is observed in 30-90%. From 40-70% of the cases require at least 1 unit of red blood cell transfusion. Hospitalization for febrile neutropenia has been reported in 10-20% of the relapsed/refractory DLBCL patients receiving platinum-based salvage regimens. [119, 111, 115, 116, 117, 118, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129]

In addition nonhematological toxicity seen with these regimens includes renal dysfunction, cardiac toxicity (for ifosfamide-containing regimens only), neurotoxicity in the form of confusion (ifosfamide-containing regimens), and cerebellar toxicity (high-dose cytarabine-containing regimens) (< 5% of the cases). Recently several investigators had evaluated the possibility of replacing cisplatin/carboplatin with oxaliplatin given its favorable toxicity profile. However, no significant changes in the antitumor activity or toxicity profile of current available salvage regimens has been demonstrated by this strategy. [126]
