We evaluated the local control, survival and complications of treating sarcomas in the wrist, hand, ankle and foot with limb-sparing surgery (LSS) and postoperative radiotherapy (PORT). Patients and Methods: Seventeen patients with STS in wrist, hand, ankle and foot who received PORT after LSS from August 2008 to November 2015 were retrospectively reviewed. Primary outcome was 5-year local recurrence-free survival (LRFS). Secondary outcomes were 5-year distant metastasis-free survival (DMFS) and toxicities. Results: The median age was 32 (range=12-78) years. The most frequent STS location was the foot in 11 patients (64%) followed by two patients each in the wrist, hand and ankle, respectively. Fourteen patients (82%) underwent wide resection with flap grafts and the same number of patients achieved clear resection margins. The median postoperative radiation dose was 54 (range=46-60) Gy. Five patients also received chemotherapy. At a median follow-up of 39 (range=6-87) months, 5-year LRFS and DMFS were both 100%. Only one patient experienced grade 3 radiation dermatitis and there was no major wound complication. Radiation-induced bone fracture occurred in two patients. Conclusion: PORT after LSS showed excellent local control for STS in the wrist, hand, ankle and foot. Considering the good local control and saving of limb function without any significant toxicity, the combination of LSS followed by PORT could be an appropriate and safe modality for STS of the distal extremities.
