Abstract

Up to 60% of patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL) do not respond to second-line (salvage) chemotherapy and hence are not offered autologous hematopoietic cell transplantation (AHCT). The utility of further salvage chemotherapy in an attempt to proceed with AHCT remains undefined. The authors reviewed 201 patients with DLBCL relapsed/refractory to anthracycline-based chemotherapy who received first-line salvage chemotherapy containing cis-platinum. Of the 120 non-responders to first-line platinum-based salvage chemotherapy, 73 received second-line salvage chemotherapy. The response rate to second-line salvage chemotherapy was 14%. Factors predicting lack of response were progression on primary therapy (p = 0.007), abnormal lactate dehydrogenase findings (p = 0.0027) and tumor bulk (p = 0.013) at second progression. Eight patients who responded received AHCT and appeared to have comparable survival to those transplanted after one salvage regimen. The authors conclude that the utility of second-line salvage chemotherapy is low, and that it is best reserved for patients demonstrating initial anthracycline sensitivity and low tumor burden.
