Irinotecan for the treatment of cervical cancer.

Topoisomerase inhibitors have been widely studied for the treatment of refractory or recurrent cervical cancer. Various schedules have been used, with response rates ranging from 13% to 20%. The combination of cisplatin and irinotecan (CPT-11, Camptosar) is being studied in cervical cancer. Hematologic and gastrointestinal toxicities have been observed. Gastrointestinal toxicities have been particularly problematic at high irinotecan doses. Further studies of irinotecan in combination with other drugs and radiotherapy are warranted.
