Echinomycin (NSC 526417) in squamous-cell carcinoma of the cervix. A phase II trial of the Gynecologic Oncology Group.

Twenty-eight evaluable patients with advanced or recurrent squamous-cell carcinoma of the cervix were treated with 1,500 micrograms/m2 of echinomycin every 4 weeks. All patients had prior chemotherapy. Two patients had partial responses (7% response, 95% confidence interval for response of 1 to 24%). The major toxicity was nausea and vomiting. Myelosuppression and other toxicity were modest. Echinomycin, at this dose and schedule, displays minimal activity in patients with squamous-cell carcinoma of the cervix who have had prior chemotherapy.
