[The treatment of retroperitoneal soft tissue sarcomas an analysis or 110 cases]

We analyzed the treatment results of 110 patients with retroperitoneal soft tissue sarcomas. Liposarcoma (31.8%) was most common followed by leiomyosarcoma and malignant peripheral nerve sheath tumors (11.8% and 11.8%, respectively). Complete resection was performed in 56 patients (50.9%), of which 18 underwent reoperation for 2-4 times. Adjacent organs were included in 13 patients in the en bloc rejection. Overall 5-year survival rate was 55.6% for those undergoing complete resection, compared to 11.1% and 6.6% respectively for those undergoing partial resection and biopsy only (P < 0.001). 37.5% of patients survived 5 years after their recurrent tumors were completely resected. Adjuvant radiation therapy or chemotherapy failed to have significant impact on survival.
