    Abstract:
    Twenty-two cases of sarcomas arising from irradiated soft tissues were observed in 531 patients operated on for soft tissue sarcomas over 38 years in our Department. Eleven women were initially irradiated for cervical cancer (ce-ca), two for endometrial cancers. The remaining nine patients were irradiated for other lesions, malignant or benign. The median interval between the radiation for uterine cancer and the outcome of clinical symptoms of a sarcoma was 18 years. Sarcomas more frequently arose in the posterior fields (buttock or sacral region in nine patients) than in the anterior (pubis, hypogastrium-four patients). The infiltration of skin was almost always present (10/13), in seven cases with an ulceration (7/13). Histologically, four hemangiosarcomas, four fibrosarcomas, three malignant fibrous histiocytomas and two neurofibrosarcomas were found. The irradiation administered to ce-ca patients consisted of radium (22.0 mcd to 58.0 mcd) and an external radiation from X-ray units (except in one case) from two pairs of two anterior and posterior fields, with skin doses of 3200 cGy to 4200 cGy directly on one field plus several hundreds cGy from the opposite field. Three-year overall survival rate was low (30%) similar to that observed in patients with primary high-grade (G-3) sarcomas. We observed more cases subjected to radiotherapy for cervical cancer than might be expected.
