A prospective and descriptive study was carried out in the Oncology Unit of the Hospital General de la Secretaria de Salud in 10 patients diagnosed with soft tissue sarcomas, corroborated by histopathology, who had already undergone one or more surgeries and have been treated several times with radio- and chemotherapy. The patients had tumors larger than 5 cm in diameter and had completed laboratory and imaging exams. The radiotherapy was administered in the modality of hypofractionation, which consists of a smaller number of sessions, with the dose/session being higher than the standard, administered twice a week. The dose was 4,000 cGy in four weeks (eight sessions), using photons of cobalt 60 with the Phoenix® equipment, and depending on the tumor’s location the procedure was done in an individualized way, leaving a lapse of three weeks during which they were clinically assessed in order to plan the overdose of 2,000 cGy in two weeks (ten sessions). Patients were transferred to radiotherapy as soon as possible, in order to receive the first dose of radiation between 60-90 minutes after the procedure was completed. There were no deaths attributable to the procedure.
