Abstract

乳房温存療法後に46~60Gyの放射線照射を行った201例の中4例(2.0%)の放射線肺炎を経験した.いずれも照射終了後7週から20週で咳漱で発症し,胸部X線写真でも照射野に一致した間質性肺炎像を示した. 3例に副腎皮質ステロイドの内服を要したが,いずれも重篤化せず転快した.乳房温存手術後に乳房照射を行った場合に咳漱等の症状が続いた時には,放射線肺炎を念頭に置き診断,治療にあたることが必要である.

Between 1983 and 1996, a series of 240 patients with early stage breast cancer were treated with breast conservative treatment, and 201 patients of them all received irradiation at a dose of 46-60 Gy to the affected breast. Among the 201 patients who received breast irradiation, four (2.0%) patients experienced radiation pneumonia. These four patients with radiation pneumonia presented with coughing from 7 to 20 weeks after irradiation. Chest X-ray film revealed interstitial pneumonia in a lung field where coincided with the irradiated field in them. Three out of four patients demanded steroids, but all patients got well within 4 months. Radiation pneumonia following conservative surgery and radiotherapy for breast cancer is an infrequent complication, but attention should be paid to radiation pneumonia if the patient suffers from persistent coughing after radiotherapy.
