Abstract
Aims: The current study aims to present epidemiologic changes and clinical aspects of Merkel cell carcinoma (MCC) in Brazil. Methods: Data were collected fromthe Brazilian Population-Based Cancer Registries (2000-2015) and Hospital-Based Cancer Registries (2000-2017). Results: The average age-standardized incidence rates significantly increased in men between the years 2000 (0.31/1,000,000) and 2015 (1.21/1,000,000), with an annual percentage change of 9.4 (95%CI: 4.7-14.4;p<0.001). In women, the incidence rates rose insignificantly in the period with an annual percentage change of 3.1 (95%CI: 0.0-6.2;p<0.10). From the hospital-based database, 881 MCC patients were identified. Most of the patients were females (51.2%), aged>60years (82.2%), White (67.6%) and diagnosed at stages III or IV (50.5%). Conclusions: A key aspect of public health promotion is to understand the incidence and morbidity of MCC.
