Although small-bowel metastasis of lung cancer is unusual, the number of such reports is increasing. In this report, we intend to clarify clinicopathological features of lung cancer metastasis to the small intestine and to determine the indication for surgical treatment. Small-bowel metastases were present in 4 of 877 patients with primary lung cancer during the recent 11-year period at Toranomon Hospital. All 4 patients underwent surgical resection after acute abdominal symptoms. Three of the 4 had other organ metastasis and died within 3 weeks because of postoperative complications and one without other organ metastasis survived 7.5 months postoperatively. Although the prognosis of lung cancer metastasis to the small bowel is poor, surgery is still indicated for palliation in otherwise fatal circumstances.
