Concurrent weekly cis-platinum in a dose escalating manner and conventional radiotherapy was evaluated in advanced cervical cancer. The toxicity of weekly cis-platinum given 2 hr before standard fractionation of radiotherapy was assessed using the modified GOG toxicity criteria. Sixteen patients having parameters indicating high risk for conventional therapy failure including positive pelvic and paraaortic nodes and intraperitoneal spread were entered. There was no life-threatening toxicity. The toxicity of the administered chemotherapy was only moderate. Patient compliance was good as at the 20 mg/m2 dose level, 79% of the prescribed doses were administered. The use of adjuvant cis-platinum in poor prognosis advanced cervical cancer merits further study.
