Summary
We examined the usefulness of radiotherapy for bone metastasis after esophageal cancer surgery. Between 2001 and 2016, we performed surgical resection for esophageal cancer in our department and 11 patients had postoperative bone metastases. Of these, 7 underwent radiotherapy. The median age was 71(60 to 76)years, with 5 males and 2 females. Six cases were squamous cell carcinoma and 1 case was adenocarcinoma. Metastatic sites included 3 vertebral bodies, 2 ribs, 2 skull bones, 1 ilium, 2 humerus, and 1 femur(there was overlap). Six cases also had other distant metastases. Three cases also underwent chemotherapy. Four of 7 cases(57%)showed reduction of metastatic lesions. The pain improvement rate was 57%. Radiation therapy for bone metastasis in esophageal cancer is thought to be effective for reduction of metastatic lesions and pain relief.
要旨
食道癌術後骨転移に対する放射線治療の有用性を検討した。2001～2016年に当科で食道癌に対し根治術を施行し,術後骨転移を11例に認めた。このうち放射線治療を施行した7例の検討を行った。年齢は中央値71(60～76)歳で,男性5例,女性2例であった。病理組織型は,扁平上皮癌6例,腺癌1例であった。転移部位は椎体3例,肋骨2例,頭蓋骨2例,腸骨1例,上腕骨2例,大腿骨1例(重複あり)であった。6例は他の遠隔転移も認めており,うち3例は化学療法も併用した。57%(4/7例)で転移巣の縮小および疼痛の軽快を認めた。食道癌の骨転移に対し,放射線治療は転移巣の縮小および疼痛緩和に有効と考えられる。
