Successful surgical treatment of solitary adrenal metastases from non-small cell lung cancer: case report.

Lung cancer is one of the most common types of maligancies and has been one of the leading causes death due to cancer for a long time. Although surgery is the treatment of choice for patients with non-N2 localized disease, most of the lung cancer patients are found to have metastatic lesions at the same time as initial diagnosis. The median survival of patients with metastatic lung cancer is less than one year even when systemic chemotherapy is given. We present a patient with non-small cell lung cancer with no initial evidence of metastasis. He underwent curative resection of the primary tumor followed by local radiotherapy. Adrenal gland metastasis was found fours years after the first surgery. After surgical resection of this metastatic lesion, followed by adjuvant chemotherapy, this patient's survival was prolonged with no evidence of disease recurrence until now. The prolonged survival of this patient may be due to a slow rate of progression of the primary tumor.
