Abstract

Background and Objectives

Soft tissue sarcoma localization in distal extremities (DESTS) of the limbs (hand/fingers, and foot/toes) is unusual. The literature is scarce about their behavior and this study was designed to assess their epidemiological characteristics, outcomes, and prognosis compared to other limb localizations (OLSTS).

Methods

From 1980 to 2010, adult DESTS and OLSTS in 22 centers were included. Demographics, tumor type, treatment modalities, and latest follow-up status were collected. Primary endpoints were overall survival and local/metastatic recurrence incidences.

Results

Two hundred five DESTS and 3001 OLSTS were included. The patients were younger, with more female and smaller tumors in DESTS. There were more clear cell/epithelioid sarcomas, synovial sarcomas, and myxoid liposarcomas vs more dedifferentiated liposarcomas in OLSTS. DESTS tumors were less irradiated and more often amputated (24.3% vs 3.4%). The five-year survival rate was 78.2% compared to 68.6% in OLSTS and after multivariate analysis, STS localization did not impact survival or local/metastatic recurrence.

Conclusion

Though rare and smaller than other limb localizations, DESTS are to be considered as aggressive. Despite a higher amputation rate, the prognosis remains the same as in OLSTS. Limb sparing vs amputation should be carefully assessed in DESTS, especially if grade 3 or of a poor prognosis histological subtype.
