Abstract

Both laboratory and clinical data suggest that hypoxia contributes to the failure of radiotherapy to achieve local control of bulky gynecologic tumors. As part of a Phase I trial of hypoxic cell radiosensitizers, 19 women at Stanford University with advanced (n = 6) or recurrent (n = 13) pelvic neoplasms were treated with radiotherapy plus desmethylmisonidazole. Complete or partial response occurred in 42% of patients with some patients achieving local control for over 1 year. It is unknown if the sensitizer added to the results of radiotherapy alone. A Phase I trial of a theoretically superior sensitizer, SR-2508, is soon to begin. It is anticipated that the dose-limiting neurotoxicity seen with misonidazole and desmethylmisonidazole will either be eliminated or will occur at a much higher total dose of drug. Many patients with gynecologic tumors could potentially benefit from participation in the new drug trials.
