Waldenstrom's macroglobulinemia (WM) is a rare and indolent B-cell lymphoma. To investigate the type and survival of hematologic secondary malignancies (SMs) in Chinese patients with WM, we retrospectively reviewed the characteristics of 102 patients with WM from February 2002 to May 2023 in our center. Four men and two women were diagnosed with hematologic SMs. Of the six patients with hematologic SMs, one was diagnosed with acute myeloid leukemia (AML), one with multiple myeloma (MM), one with myelodysplastic syndrome (MDS), one with B-cell acute lymphoblastic leukemia (B-ALL), and two with diffuse large B-cell lymphoma (DLBCL). The median age was 65.5 years (56-74 years). The median interval time between diagnosis of WM and hematologic SMs was 39.5 months (10-117 months). Among those with WM with hematologic SMs, five died and one survived. Overall survival (OS) was just 33 months (12-119 months) on median. A total of 32 patients died and 64 survived in the group of WM without hematologic SMs, and the median OS was 82 months (3-250 months). This is the first study in the Chinese population on hematologic SMs in WM. The purpose of this study was to investigate the prognosis of hematologic SMs in WM in the Chinese population, as well as to compare the population's characteristics to those of other centers. We investigated the underlying causes further and presented a research strategy for our forthcoming investigation. We intend to investigate risk factors for SMs as well as more accessible screening methods.
