Popis: Radical dose radiation therapy alone or combined with limited surgery has been employed in the management of 100 patients with primary (71) and recurrent (29) sarcoma of soft tissue. Results of this experience show that a combination of conservative surgery and radiation therapy, based upon radical dose levels and sophisticated techniques, is effective: only 13 of 100 patients showed local regrowth during a followup of 2-12 years. This may be compared with an expected congruent to 25 recurrences had treatment been radical surgery (wide resection or amputation). For lesions located on the distal extremities (elbow-hand, knee-foot) there were local failures in only 3 of 59 (5 percent). Further, 75 percent of patients treated by the improved techniques utilized in the recent 8 years retained a useful limb which is free of pain or edema. Histopathologic grade is demonstrated to be an important indicator of prognosis of local recurrence and of disease-free survival. Local recurrence rates were 0/23, 9/53, and 4/24 for Grades 1, 2, and 3. Disease-free survival rates were 19/23 (86 percent), 27/53 (51 percent), and 4/24 (17 percent) for Grades 1, 2, and 3, respectively. Invasion of skin appeared to be a sign of poor prognosis; 8 of 9 such patients developed distant metastases.
