Unusual intra-abdominal metastases from carcinoma of the lung.

Eleven patients with bronchogenic carcinoma underwent surgical treatment of metastatic abdominal visceral lesions. Successful surgical palliation was achieved in nine. In eight patients intraabdominal metastasis marked the first clinical sign of spread of the primary tumor outside the chest. The longest interval following diagnosis of the primary lung lesion and the appearance of the abdominal symptoms due to metastatic disease was three and one-half years.
