This study aims to perform a broad evaluation and description of the epidemiological profile, access to treatment and main clinical outcomes of the Brazilian STS patient. Methods: A population-based cohort study of 66,825 patients who underwent procedures related to STS treatment registered in the Brazilian public health system (Sistema Único de Saúde, SUS) databases. Results: Median age was 57 years, 30% of them older than 65 years, and 50.7% of the cohort was female. The majority, 50,383 patients (75.4%), was diagnosed between 2008 and 2015. Most prevalent anatomic sites were head and neck (13.6%) and upper and lower limbs (12.6%). The registry of sarcomas without a specific location comprehended 29.7% of the cohort. The majority of patients resided in the Northeast (40.2% of the patients). Surgery was the first treatment modality in 77.7% of the cases. The 1,5 and 10 y survival were: 82%, 57% and 42%, in line with international data. Male gender, age above 65 years old and with STS of the peritoneum and retroperitoneum, thorax and torso, were identified as negative prognostic predictors. Conclusion: This 66,825 patient cohort demonstrates Brazilian’s reality about the epidemiology and treatment of the STS, and may contribute to a reorganization of the health system, as well as provide a positive impact on the patients’ clinical outcomesAcesso abertoEpidemiologia, Tratamento, Sobrevida, Sarcoma de partes moles; Soft tissue sarcoma, Survival, Epidemiology, TreatmentDissertação4.01.00.00-6 - Medicina
