Postradiation sarcoma of the chest wall: report of two cases.
Postradiation sarcoma is a rare late complication of external radiotherapy. We herein present two cases with this disease. A 54-year-old man had undergone a lobectomy and chest wall resection for Pancoast type lung cancer 7 years previously. He had undergone irradiation with a total dose of 50 Gy. Computed tomography (CT) demonstrated a tumorous expansion of the right lateral thoracic wall. A pathological examination confirmed a diagnosis of osteosarcoma. A 60-year-old woman had undergone a resection of the lateral chest wall mass, which was diagnosed to be Hodgkin's disease in 1991. Chemotherapy was given postoperatively. A tumorous lesion arose again and irradiation was performed with a total dose of 110 Gy. In 2000, two tumors appeared in the irradiation field. A pathological examination showed a sarcoma with divergent differentiation. In 2003, a tumor recurred and was diagnosed to be a liposarcoma. Patients who have received radiotherapy should therefore be followed up while taking into consideration the possible development of postradiation sarcoma.
