Local recurrence after surgical resection is the main cause of disease‐related mortality in patients with primary retroperitoneal sarcoma (RPS). This study analysed predictors of local recurrence and disease‐specific survival.
A prospective database was reviewed to identify patients who underwent surgery for primary RPS between 1990 and 2009. Patient demographics, operative outcomes and tumour variables were correlated with local recurrence and disease‐specific survival. Multivariable analysis was performed to evaluate predictors for local recurrence and disease‐free survival.
Macroscopic clearance was achieved in 170 of 200 patients. The median weight of tumours was 4·0 kg and median maximum diameter 27 cm. Resection of adjacent organs was required in 126 patients. The postoperative mortality rate was 3·0 per cent. Seventy‐five patients developed local recurrence during follow‐up. At 5 years the local recurrence‐free survival rate was 54·6 per cent and the disease‐specific survival rate 68·6 per cent. Inability to obtain macroscopic clearance at resection and high‐grade tumours were significant predictors for local recurrence and disease‐specific survival.
Complete macroscopic excision should be the goal of surgical resection. Ability to resect a RPS completely and tumour grade are the most important predictors of local recurrence and overall survival.
