Is fractionated robotic stereotactic body radiosurgery optional salvage treatment for the re-irradiation of locally recurrent nasopharyngeal carcinoma?

Purpose: Recurrent nasopharyngeal carcinoma (NPC) after previous radiation therapy is a significant problem. This study was to determine the potential benefits from re-irradiation by fractionated stereotactic body radiotherapy (FSRT) on survival benefits and effects of severe late toxicities.

Materials And Methods: Between 2009 and 2018, treatment outcomes were evaluated retrospectively in 26 patients with locally recurrent NPC treated using FSRT with CyberKnife.

LONG-TERM RESULTS OF EXTREMITY SOFT TISSUE SARCOMAS LIMB-SPARING SURGERY AND RADIOTHERAPY.

Objective: To assess the prognostic factors and results of limb sparing surgery and postoperative radiotherapy (PORT) in patients with non-metastatic soft tissue sarcomas (STS) of the extremities.

Methods: Between 1980-2007, 114 extremity-located STS treated with PORT were analyzed retrospectively. Tumors were mostly localized in the lower extremities (71,9%).
