AIM: To evaluate local control for long-term prognosis in retroperitoneal soft-tissue sarcoma (primary tumors (PT) and local recurrence (LR)).
METHODS: A total of 110 patients underwent surgery between 1988 and 2002. Prospectively gathered clinicopathological data were analyzed. Kaplan-Meier estimations and Cox regression analyses were performed.
RESULTS: Resectability was 90%, being comparable for PT (n=71) and LR (n=39). Morbidity, mortality, blood loss, and operation time did not differ for PT or LR (24% vs. 31%, p=0.41; 7.0% vs. 5.1%, p=1.0; 1000 ml vs. 1500 ml, p=0.17; 240 min vs. 255 min, p=0.13). Hospitalization was comparable in both groups (median, 12 days (PT) and 13 days (LR)). Follow-up was 89 months (median, IQR 37-112 months). Local 3- and 5-year control rates after complete resection of PT were 66% and 59% (19% and 9% for LR, p<0.001). The mean number of operations were 1.4 for PT and 2.4 for LR (p=0.0047). The 5-year survival rates after complete resection were 51% for PT and 43% for LR (p=0.39). The 5-year survival rateswere 65%, 4%, and 0% for complete resection, incomplete resection, and exploration, respectively (p<0.001). Multivariate analysis showed high-grade and blood loss with a poor prognosis.
CONCLUSIONS: Comparable resectability rates and perioperative outcome were observed for surgery of PT and LR. Consequent reoperation leads to respectable long-term survival rates after resection of LR. The prognosis in retroperitoneal sarcomas varies significantly according to resectability, grade and blood loss.
