膀胱癌に対する膀胱全摘出術後の経過観察指針についての検討

Abstract

膀胱癌に対して膀胱全摘出術を施行した111症例(pT1以下56例, pT2 22例, pT3以上33例)を対象に, 再発部位及び診断時期と術後の経過観察について検討した.その結果, 尿路外再発は29症例であり, 再発部位は30例で, 骨盤内再発は10例(pT1以下3例, pT2 1例, pT3以上6例), 骨盤外は20例((pT1以下2例, pT2 4例, pT3以上14例)であった.再発部位別では骨盤内, 骨, 脳が診断契機となる頻度が高く, 後腹膜リンパ節及び肺は低い傾向が見られた

With the aim of developing stage-dependent follow-up strategy after radical cystectomy for bladder carcinoma, the records of 111 patients with bladder carcinoma who underwent radical cystectomy during the period between 1986 and 2003, were reviewed for the date and site of recurrence. Intrapelvic recurrence developed in 3 out of 56 patients with pT1> or =, 1 of 22 with pT2 and 6 out of 33 with pT3 or =, 4 with pT2 and 14 with pT3 or =, 4 with pT2 and 14 with pT3 or =. A stage-specific approach to tumor surveillance after radical cystectomy for bladder carcinoma, taking into consideration the risk of recurrence, represents a new approach for efficiently detecting recurrence and reducing medical costs. Our results offer the possibility of a new stage-specific approach to tumor surveillance after radical cystectomy for bladder carcinoma, for efficiently detecting recurrence and reducing medical costs, taking into consideration the risk of recurrence.
