内容紹介
Summary
A 57-year-old man underwent curative resection for StageⅠ sigmoid colon cancer; 6 years later, lung metastasis was detected and subsequently resected. Eight years after the first curative resection, retroperitoneal metastasis was detected and subsequently resected. Nine years after the first curative resection, a growing tumor was detected at the bottom of the right lower lobe of the lung. Partial lung resection was performed; pathological examination revealed a secondary tumor formed as a result of colon cancer metastasis. When we searched previous cases of late recurrence in colorectal cancer, the primary colorectal cancer was classified as StageⅠ or Ⅱ in more than half of the cases. Therefore, even after curative resection of StageⅠ colon cancer, late recurrences may occur.
要旨
症例は67歳,男性。57歳時にStageⅠのS状結腸癌に対して根治切除術が施行された。術後6年目に肺,8年目に後腹膜に異時性再発を来し,それぞれ切除された。今回,術後9年6か月に右肺底区に増大する結節を認め,右肺下葉部分切除術が施行された。病理学的診断にて大腸癌肺転移と診断された。大腸癌根治切除後5年以上経過再発例を検索したところ,原発巣StageⅠ/Ⅱが半数以上を占めていた。本症例のようにStageⅠ大腸癌根治切除後であっても遅発性再発が起こり得ることを念頭に置くべきである。
