I'd like to clarify information in my article on cervical cancer ("Taking a Stand Against Cervical Cancer," May 2004). According to the research I'm seeing, the investigational drug ZYC101a is being used to treat human papillomavirus in high-grade dysplasia (or carcinoma in situ), not high-grade cervical cancer.
