Hepatic irradiation in the management of metastatic hormone-secreting tumors.

ABSTRACT

Three patients with extensive liver metastases from hormone-secreting tumors were treated with external beam radiation therapy to palliate signs and symptoms of tumor mass and/or hormone secretion. These patients experienced an objective response of 3, 14, and 24 months duration, respectively, as measured by plasma hormone levels and/or computed tomography (CT) scanning. Using conventional fractionation, a dose of 2400 to 3000 rad was delivered without significant acute or late toxicity. Although these tumors have a long natural history (many years), even after the development of liver metastases, radiation therapy can provide effective palliation and should be considered as a therapeutic option.
