Flap reconstruction and interstitial brachytherapy in nonextremity soft tissue sarcoma.

Radiotherapy is an integral component of management of high-grade soft tissue sarcomas. Interstitial brachytherapy is used to deliver a boost or radical dose with several advantages over external beam radiotherapy. There has always been a concern to use brachytherapy with flap reconstruction of skin defects after wide excision. We preset our initial experience with interstitial brachytherapy in two patients of recurrent high-grade non-extremity sarcomas treated with surgical excision and soft tissue reconstruction of surgical defect.
