Abstract
Pentoxifylline (PTX) has pharmacological properties that suggest potential utility as a radiation sensitizer, and preclinical animal studies have been promising. In a non-randomized phase II trial, we used PTX plus standard-dose external-beam whole-brain radiation treatment (WBRT) in patients with brain metastases. Seventeen patients were entered; 14 received both WBRT and PTX and were considered evaluable. Nine of the 14 completed treatment. Analyzing data on all 14 evaluable patients according to intent to treat, median survival time was 33 days, comparable to published data from historical controls. PTX toxicity was not a common cause of patient dropout, supporting higher PTX doses in future trials.
