Surgical treatment of adrenal metastasis following pulmonary resection for lung cancer: comparison of adrenalectomy with palliative therapy.
Although adrenal metastases from lung cancer are frequently detected during the late clinical stage or at autopsy, they are rarely surgically treated following pulmonary resection for lung cancer. We detected adrenal lesions as initial clinical recurrence in 9 (1%) of 904 patients who underwent pulmonary resection for lung cancer at our institute between 1980 and 1992. Adrenalectomy was performed in five who had developed unilateral adrenal metastasis. One underwent simultaneous operation for primary and metastatic lesions, and 4 underwent adrenal surgery following pulmonary resection. The adrenal tumor was removed via laparotomy in three patients, and via posterolateral non laparotomic approach in two. Co-metastatic lesions which were detected incidentally at operation included intestinal metastasis in two patients and regional lymph node metastasis in two; these were simultaneously resected. Following adrenalectomy, all these patients were treated with adjuvant chemotherapy or radiotherapy. Two patients have remained free of relapse for 40 and 26 months, respectively, after adrenal surgery, while three died of other distant metastases more than 9 months after adrenalectomy. In contrast, the four patients who received chemotherapy or radiation therapy died less than 6 months after palliative therapy. Thus, we consider that surgical treatment for adrenal metastases following pulmonary resection for lung cancer is effective in selected cases. The indications for adrenalectomy are presented in comparison with those for palliative therapy, and several difficulties in the surgical management of adrenal metastases are discussed.
