title: Palliative radiotherapy for symptomatic adrenal metastases.
abstract: To evaluate the role of palliative radiotherapy for adrenal metastases, a retrospective review was performed on 16 patients treated between 1972 and 1988 for palliation of symptomatic adrenal metastases. The median patient age was 56 years. In 15 cases lung cancer was the primary site (7 adenocarcinomas, 3 squamous cell carcinomas, 3 large cell carcinomas, and 2 small cell carcinomas) and in 1 case there was an unknown primary (squamous cell carcinoma). Ten of 16 patients were treated with 3000 cGy to opposed anterior and posterior fields (300-cGy fractions [four patients] and 250-cGy fractions [six patients]). The remaining six patients were treated with a variety of techniques, with total doses ranging from 2925 cGy to 4500 cGy. The patients were analyzed for response at their first follow-up visit (2 to 4 weeks after treatment). The overall response rate was 75% (12 of 16 patients). Six patients (38%) had complete pain relief without medication that lasted until death. Two patients had marked pain relief, but still required analgesics. Four patients had marked or moderate pain relief that did not continue through follow-up. Four patients had minimal to no response. All patients were observed until death, with a median survival time after irradiation of 3 months (range, 0.5 to 11 months). Although the prognosis for patients with adrenal metastases is poor, radiotherapy to symptomatic adrenal metastases can be administered with a high probability of achieving effective palliation.
