Primary chest wall soft tissue sarcomas: predictors of survival following surgical resection in a large population cohort.

10571 Background: Primary soft tissue sarcomas (STS) of the chest wall are rare entities with limited information regarding treatment and oncological outcomes. The aim of this study is to evaluate the outcomes of surgical treatment in malignant primary chest wall STS and identify factors affecting survival using the Surveillance, Epidemiology, and End Results (SEER) database. Methods: We conducted a retrospective analysis using the SEER database (1988 -2010) and queried for all patients with primary chest wall STS. Only adult patients with histologically confirmed single primary tumor undergoing curative surgical resection were included in the study. Primary outcome was overall survival; covariates included demographics, tumor pathology, radiation and type of surgical procedure as coded in SEER (Simple/Partial or Total/Radical). Chi-square tests were performed to analyze categorical variables. Kaplan-Meier and Cox regression analyses were used to evaluate overall survival. Results: A total of 1053 cases o...
