Half and total body radiation for carcinoma of the prostate.

Despite recent advances in the treatment of stage D carcinoma of the prostate many patients become refractory to all therapeutic modalities. Progressive and incapacitating pain is one of the most difficult symptoms to manage. Ten patients with severely symptomatic metastatic adenocarcinoma of the prostate have been treated with either single or sequential doses of half body radiation using 800 rad delivered by a Linac 10 mV linear accelerator. There were 15 courses of half body radiation delivered and a good to excellent response was noted in 11 instances. Results often were immediate and the duration of the response was variable. Treatment was well tolerated with no fatal complications. Half and total body radiation appears to offer significant palliation and its use with other forms of therapy warrants further investigation.
