Investigators tried condult a retrospective study to analysis the prognostic factors and oncological outcome analysis of Retroperitoneal Sarcoma treated in our high volume medical center.
Retroperitoneal Sarcoma (RPS) which is a rare disease which incidence is 1.79/100,000. The treatment is difficult to due to it anatomy position which often invade to multiple organs and cause the complete surgical resection to be very complex and difficult. It was known to sacrifice one side kidney will improve the resection rate. To this days, successful surgical resection was still the gold standard that provide most benefit in overall survival. To reach that goal, pre-operative radiotherapy was applied to RPS which intended to achieve similar effect in rectal cancer for the down staging effect and improved the respectability but with limited benefit. Herein, investigators conducted this study to find the best way to achieve successful surgical resection and prognostic factor analysis.
