Brief Summary

Soft tissue sarcomas are rare malignant tumors. Liposarcoma constitute the most frequent histological subtype of retroperitoneal sarcoma. The prognosis of soft tissue sarcomas depend on clinical and histologic characteristics. Objective: Evaluate variables that may be related to overall survival and local recurrence free survival in patients with retroperitoneal liposarcoma. Methods: retrospective analysis of medical records of 60 patients attended from 1997 to 2017, who underwent surgical resection of retroperitoneal liposarcoma.

Study Population

60 patients attended at the University of São Paulo Medical School Hospital (HC-FMUSP) and the Cancer Institute of the State of São Paulo (ICESP) from 1997 to 2017, who underwent surgical resection of the primary tumor at these institutions, as well as those referred after resection at other services.

You may qualify if:
