The aim of this study was to evaluate the outcome of patients with soft tissue sarcoma of the extremity and abdominal wall. This is the retrospective analysis of patients from a prospectively maintained data base from a single institute. We identified 79 patients with intermediate- to high-grade soft tissue sarcomas who were treated at our institute between Jan 2015 and July 2018. Low-grade tumors were excluded. There were 60 males and 19 females with a mean age of 44.6 years. Of the 79 sarcomas, 50 were in the lower limb and 24 in the upper limb and 5 were in abdominal wall. The commonest subtypes were undifferentiated pleomorphic sarcoma (n = 21) and synovial sarcoma (n = 19). Only 9 patients had metastatic disease at presentation. All 79 patients underwent surgical resection with an intent to achieve clear margins. Amputation was done in 19 patients while wide excision of the tumor was done in 60 patients. Adjuvant radiotherapy was given in 49 patients while adjuvant chemotherapy was given in 35 patients. At last follow-up (73 patients), 48 patients are alive without disease, 9 are alive with disease, 12 patients had died of disease, and 4 patients died due to other causes. Overall survival (OS) for 3 year is 77.6%, and estimated mean survival is 55.05 months. Relapse-free surviva (RFS)l at 3 year is 74.3%, and estimated mean RFS is 51.78. The only independent factor that affected the OS was the dimension of primary tumor (p = 0.02). For disease-free survival, the independent factors that affected outcome were stage at presentation (p = 0.04) and dimension of the tumor (p = 0.04). Short-term results shown by this study shows good outcome in patient with intermediate- to high-grade sarcomas when multidisciplinary approach is utilized for the management. Patients who had metastatic disease at presentation did worse than patients who did not.
