N2 - Background Several population-based and cohort studies have reported an increased risk of second cancers in lymphoproliferative disorders (LPDs). The cause of second cancers in LPDs is probably multifactorial, and the relative contribution of treatments, genetic predisposition, and immune dysfunction typical of LPDs is still unclear. Patients and Methods We retrospectively studied 230 patients with Waldenström macroglobulinemia (WM) to assess the frequency, characteristics, and predictive factors of second cancers and to evaluate whether patients with WM are at higher risk of second cancers compared with an age- and sex-matched control population. Results In a competing-risk model, the cumulative incidence of solid cancers was 6% at 5 years, 11% at 10 years, and 17% at 15 years, whereas the incidence of hematologic malignancies was 4% at 5 years, 7% at 10 years, and 8% at 15 years. Compared with an age- and sex-matched population, the overall risk of second cancers was 1.7-fold higher than expected (95% confidence interval [CI], 1.22-2.38; P =.002). Patients with WM were at increased risk for diffuse large B-cell lymphoma (DLBCL) (standardized incidence ratio [SIR], 8.64; 95% CI, 3.88-19.22; P
