The effect of bone marrow plasma cell morphology at diagnosis on survival time was evaluated in 139 patients with multiple myeloma. According to the morphological classification scheme the patients were categorized as mature (30 patients), immature (76 patients) or plasmablastic (33 patients). The plasmablastic group had an estimated median survival (Kaplan‐Meier method) of 10.9 months, compared with 32.2 months for immature and 60 months for mature types (P = 0.0000). The prognostic value of a morphologic classification in multiple myeloma was further demonstrated by means of a multivariate linear regression analysis of survival data. Expected survival was calculated using clinical features and morphologic subtypes. The estimated survival time for plasmablastic myeloma was shorter by 51.4 months and for immature myeloma patients by 35 months, compared with mature myeloma patients with similar clinical characteristics. Plasma cell morphology at diagnosis is an important predictor of survival duration in patients with multiple myeloma.
