OBJECTIVE: Symptomatic small bowel metastases from primary carcinoma of the lung have been rarely reported. The aim of this study was to describe clinical presentation and outcome in a series of patients.
METHODS: Between 1984 and 1996, 1544 patients with lung cancer were referred to our institution for surgery and 1399 were operated on. Seven of them developed a symptomatic small bowel metastasis. Clinical, radiological, and pathology records were reviewed.
RESULTS: In 6 of 7 patients, the lung cancer was previously operated on from 0.5 to 24 months before the diagnosis of small bowel metastasis. In 1 patient, the primary tumor was diagnosed after small bowel metastasis resection. Clinical symptoms at presentation were acute peritonitis in 2 patients, progressive digestive obstruction in 3, and gastrointestinal bleeding in 2. The diagnosis was suspected on abdominal ultrasonography in 2 cases, and small bowel radiography in 3 cases. It was confirmed either by computed tomographic scan or by push enteroscopy. All patients underwent operation (intestinal resection in 6 and bypass in 1) with no postoperative death. Small bowel metastases were located in the jejunum in 2 patients, in the ileum in 3, and in both sites in 2. Histological features of the metastases were identical to the primary tumor: squamous cell carcinoma (n = 3), undifferentiated large cell carcinoma (n = 2), adenosquamous carcinoma (n = 1), and adenocarcinoma (n = 1). In 6 patients, small bowel metastases were associated with other metastatic sites. Six patients died within 8 months after metastasis resection. One patient was alive 22 months after bowel resection.
CONCLUSIONS: Symptomatic small bowel metastases can occur early in the course of lung cancer. Resection should be considered as the best palliative treatment to prevent bowel obstruction or peritonitis.
