Abstract

Patients older than 75 years old with multiple myeloma (MM) have shorter survival and are usually treated differently from what features in clinical trials. In this study, the authors characterized the Portuguese population of MM patients above 75 years old, treated between 2009 and 2016. We compared the outcomes obtained with bortezomib-based protocols (BBP), thalidomide-based protocols (TBP), and chemotherapy (CT) using univariate and multivariate controlling for age, performance status, International Staging System score, renal impairment, and number of comorbidities. We retrieved data from 386 patients, treated in 12 hospitals. Three hundred thirty-one cases were analyzed: 119 patients treated with BBP, 65 with TBP, 147 with CT. Median age was 79 years; CT-treated patients were older, had a worse performance status, and have more comorbidities. The median follow-up was 25 months. The 2-year OS was 58% and the median OS was 29.5 months. Patients treated with BBP had more frequently very good partial response (VGPR) or better response, and the subgroup of more fit patients had a significantly longer progression-free survival (PFS) and OS. The most frequently grade 3–4 toxicities were hematologic, infectious, and neurologic and were significantly lower in TBP and CT groups vs BBP. The most common second line was CT, followed by lenalidomide. Patients treated with lenalidomide had a higher probability of VGPR or better and a superior 1-year PFS. Despite the limitations of a retrospective study, our cohort represents the reality of older patients with MM in a western country. The hazard of death or progression was higher for old, fit patients treated, in first line, with CT and with TBP compared with that of BBP.
