Invasive cancer of the cervix after cryosurgery. Pitfalls of conservative management.

ABSTRACT

Eight cases of invasive cervical carcinoma detected after cryotherapy for presumably noninvasive cervical lesions are reported. Three of these patients died from their disease less than 2 years following definitive therapy. The potential dangers of a less-than-optimal work-up of patients prior to freezing are analyzed and discussed in detail. Possible explanations for failures of cryotherapy are discussed, and guidelines for prevention of failures are presented.
