In the natural history of lung cancer, small bowel metastasis is a rare complication. We experienced two cases of small bowel metastases from carcinoma of the lung. One was a 75-year-old woman with the onset of diffuse peritonitis due to small bowel perforation. The another was a 65-year-old man with complete obstruction of small bowel.
Until the abdminal symptoms appeared, they had not been diagnosed as having cancer. After the resection of metastatic carcinoma of small intestine and postoperative irradation therapy to the pulmonary lesion the patients were discharged. Histological diagnoses of both cases were squamous cell carcinoma. Both of them died within 32 weeks after their operations.
According to 16 operations (9 cases in English and 7 cases in Japanese) for the small bowel metastases from lung cancer have been reported.
In conclusion, the best operative procedure is intestinal resection with end-to-end anastomosis. But the rate of operative deathi s high (50%). The average survival time of the patients who could tolerate the surgery is about 20 weeks.
Postoperative irradiation therapy to pulmonary lesion seems to have good effects on survival time.
