Compartmental resection for subfascial extremity soft tissue sarcoma and quality of life in long-term survivors

Abstract

The surgical management of soft tissue sarcoma has changed over the past years, resulting in an interdisciplinary multimodal approach and limb-preserving treatment modalities. From 464 consecutive patients with a soft tissue sarcoma (STS) of an extremity, a compartmental resection was performed in 82 patients, usually for primary subfascial large tumors. Postoperative quality of life was evaluated using the EORTC Score C30. In our study population, 52% of STS was poorly differentiated, 32% moderately, and 16% well differentiated. Survival proved to be dependent on tumor grade and tumor biology, but not on tumor size. The overall survival rate was 81.5%, 71.9%, and 58.3% after 2, 3, and 5 years, respectively. Leiomyosarcoma (39%) and malignant fibrous histiocytoma (42%) are associated with poor 5-year survival rate compared to liposarcoma (82%). Metastases were observed in 33% of T1 and 43% of T2 tumors corresponding to 51% with G3 tumors, 52% with G2 and 23% with G1 tumors. We found a decreased quality of life score in our patients in all dimensions compared to a normal population. Despite the elevated risk of a functional deficit, compartmental resection reduces the risk of local recurrence comparable to the recurrence rates after the most radical surgery limb amputation.
