title: Radiotherapy of choroidal metastases: breast cancer as primary site.
abstract: Forty-two cases of metastatic breast cancer to the choroid treated by radiation therapy were reviewed. Fifteen patients (36%) had bilateral and 27 patients (64%) had unilateral choroidal involvement. In 12 patients (29%) the choroid was the first site of dissemination. The median survival period after choroidal metastases was 10 months. Most patients were treated with Co60 in doses of 2500 rads tumor dose (TD) in ten fractions, 2500 rads, (TD) in five fractions and 3000 rads (TD) in ten fractions. An early group of patients had orthovoltage therapy. Good visual responses were obtained with each of the above treatment programs. Radiation treatment in the range of 2500-3000 rads TD in a short course is recommended for palliation of metastatic breast cancer to the choroid.
