title: Radiotherapy for adrenal gland metastasis from lung cancer: report of three cases.
abstract: Adrenal gland metastasis is often observed during the clinical course of patients with lung cancer. However, treatment of adrenal gland metastasis is seldom considered because of the systemic spread of the disease. Treatment with curative intent is very rare, but palliative treatment may sometimes be considered when symptoms such as flank pain are observed. Three cases of adrenal gland metastasis were reported. Two of them received surgery for lung cancer and developed a sole metastasis of the adrenal gland. Case 1 developed a sole left adrenal gland metastasis with left flank pain 14 months after surgery for large cell carcinoma of the lung. Curative radiotherapy after intra-arterial chemotherapy was given. A good response was obtained, and he has been alive for 2 years and 9 months. Case 2 developed a right adrenal gland metastasis after radiotherapy for brain metastasis, after having received right upper lobectomy because of SCLC. The increase in the size of the right adrenal gland led us to treat the lesion before symptoms developed. Radiotherapy was given on an outpatient basis. Case 3, who was previously treated with chemoradiotherapy for SCLC, developed brain, liver, and bilateral adrenal gland metastasis. Huge adrenal gland metastases displaced the pancreas and caused severe pain with the increase in serum amylase level. Concurrent radiotherapy with systemic chemotherapy was given and remarkable shrinkage of the adrenal gland metastases was obtained together with pain relief. Cases 2 and 3 died after 8 and 4 months, respectively. In some cases, radiotherapy for adrenal gland metastasis is a good palliative therapy even in the advanced stage patients. Radiotherapy can sometimes curatively treat adrenal metastasis from NSCLC, as in our Case 1, in which adrenalectomy appeared difficult at the time of recurrence.
