Abstract

Due to the substantial limitation of study population, Spindle cell sarcoma (SCS) was unexplored comprehensively. In this study, we investigated the clinical characteristics and disease specific prognostic factors of SCS. 3299 SCS cases were identified and extracted from Surveillance, Epidemiology, and End Results (SEER) database (1973-2017). White people account for 79.1% with median age of 57 years without predominance in any gender. Significant disease specific survival (DSS) and overall survival (OS) were found differentiated in age, T stage, N stage, M stage, AJCC stage, SEER historic stage, tumor locations, surgery, and pathologic grade. In the multivariate Cox analysis, the age >64 years (for DSS, P < 0.001 and for OS, P < 0.001; Reference age ≤64 years), AJCC stage III (for DSS, P = 0.006 and for OS, P = 0.04; Reference: AJCC stage I), and non-surgical treatment (for DSS, P < 0.001 and for OS, P < 0.001; Reference: surgery) were independently associated with worse DSS and OS. In brief, our study demonstrated that SCS mostly found in white people at fifth to seventh decades of life without gender predilection. The patient's age, AJCC stage, tumor location and surgery were independent prognostic indicators for both DSS and OS of SCS.
