RISK OF HEMOLYMPHOPOIETIC NEOPLASM BEFORE AND AFTER THYROID CANCER. A POPULATION‐BASED STUDY IN ITALY, 1998‐2012

Introduction: The number of patients living after a cancer diagnosis is increasing, especially hemolymphopoietic and thyroid (TC). This study aims at evaluating both the risk second in TC as cancer. Methods: Two population-based cohorts aged up to 84 years were identified from 28 Italian registries 1998–2012. first included cancers with cancers. Standardized incidence ratios (SIR) SPC stratified by sex, age, time since diagnosed within 2 months are not computation cancer-specific SIRs. Results: 38,535 154,820 included. Overall SIR for was significantly increased (SIR=1.5 women 1.3 men), well most subtypes (SIR=2.7 acute lymphoid leukemia, 1.6 follicular non-Hodgkin lymphomas, 1.5 chronic 1.4 myelomas sexes). overall higher all three age groups (0-34 years: 2.0, 35-54: 55+: Acute Lymphoid Leukemia (10 cases, SIR=6.1), Hodgkin lymphomas (38, 2.8), neoplasms (183, 1.8). any particularly 0-34 35-54 (SIR 4.3 1.8 respectively). Conclusions: have an developing be An elevated primary tumors use radioactive iodine (RAI) therapy patients, particular pediatric young adult may explain leukaemias hemolymphoiectic overall. present finding help designing surveillance programs vice versa keeping into consideration possibility overdiagnosis TC.
