Neoadjuvant therapy for advanced squamous cell carcinoma of the cervix: Cisplatin followed by radiation therapy—A pilot study of the gynecologic oncology group

Eleven patients with untreated advanced squamous cell carcinoma of the cervix (FIGO Stage IIIB and IVA, or positive paraaortic nodes) were treated with cisplatin 50 mg/m2 every 3 weeks for six courses prior to irradiation therapy (RT). Six patients completed six courses of cisplatin prior to RT with one complete and two partial responses (PR). Five other patients did not complete cisplatin therapy; two progressed after two and three courses, one had a PR after three courses and refused further therapy, one refused treatment after two courses and one elected to begin RT after one course. Two patients had reversible nephrotoxicity. No other major toxicity was noted. Six patients had stem cell assay prior to treatment and assay results were predictive of cisplatin response in five. Only one patient remains alive at 44+ months. Cisplatin chemotherapy prior to irradiation therapy is feasible and without substantial toxicity but is unlikely to be of benefit in patients with advanced cervical cancer.
