Clinical analysis of 251 cases of soft tissue sarcomas

Objective To explore the therapeutic principles and prognostic factors of soft tissue sarcoma. Methods Two hundred and fifty-one patients with soft tissue sarcoma (STS) treated at Shanghai Cancer Hospital during 1986 -1990 were reviewed retrospectively. Results The 1-, 3 - , 5 - , 10 - year tumor-free survival rates were 67. 74% , 57. 16% , 52, 41% , 38. 60% , respectively.The overall survival rates for 1,3,5 and 10 years were 81. 01 % ,67.75% ,60.79% ,and 49.23% respectively. Log-rank test showed that the patients with different pathological findings, histological grades,mass location and size, anatomical depth, and surgical margin showed different outcomes. Whether the sarcomas invaded the vessels or metastasized would influence the survival rates. The patients who underwent different interventions or operations also had different outcomes. The prognosis of STS was associated with age,histological type,histological grade, tumor size, surgical margin and metastasis according to the Cox regression analy
