Abstract:

Objectives: Purpose of this study was to compare prognostic factors and outcome of patients with multiple myeloma (MM) aged > 70 yr at diagnosis with those of younger patients. We also applied the recently proposed International Staging System (ISS) for MM in these patients. Patients and methods: Among 1,162 newly diagnosed, symptomatic MM patients included in our database, 357 (31%) were > 70 yr of age. Clinical and laboratory variables were evaluated in patients > 70 yr and in younger patients and were assessed for possible correlation with survival in patients > 70 yr of age. Results: Most clinical and laboratory features were similar in the two groups of patients but older patients presented more frequently with advanced ISS (P = 0.02). Despite similar response rates to primary treatment, younger patients survived longer than patients > 70 yr of age (40 vs. 28 months, P = 0.001). There was a longer survival of younger patients than that of older patients diagnosed with ISS stage 1 (median 71 vs. 54 months, P = 0.007) and ISS stage-2 patients (median: 38 vs. 26 months, P = 0.0008) but for patients with ISS stage 3 median survival was similarly poor in the younger and older age group (21 and 20 months, P = 0.283). Other variables associated with impaired prognosis were severe anemia, extensive bone marrow plasmacytosis and elevated serum LDH. Conclusions: Older patients with MM present more often with advanced ISS and have significantly shorter survival than younger patients. The ISS retained its prognostic significance within the group of elderly patients. © Blackwell Munksgaard 2005.
