Recent advances in radiotherapy for soft-tissue sarcoma

The use of radiotherapy in soft-tissue sarcoma continues to evolve. This review focuses on how current management is influenced by the most recent publications in the field. In particular, experience of patients treated without radiotherapy permits guidelines to be established that define a subset of patients who do not need radiotherapy to achieve sarcoma cure with good function. Strategies for radiotherapy delivery are discussed, including the most recent prospective results from a trial of preoperative and postoperative radiotherapy, with particular emphasis on randomized data. Also, the definitions for adequacy of surgical excision and the ability to achieve high rates of local control when margins are minimally positive are integrated into a planned approach. The difficult problem of retroperitoneal sarcoma is discussed, as are chemoradiotherapy protocols that may enhance local and systemic outcome. Finally, the potential for image-guided radiotherapy, enhanced targeting, and better radiotherapy delivery in the contemporary era is addressed.
