A clinical-pathology review of cervical intraepithelial neoplasia following cryotherapy failure.
Cervical intraepithelial neoplasia (CIN) after cryotherapy can pose both diagnostic and therapeutic problems. To clarify these issues, 27 consecutive patients who underwent cone biopsy for CIN after cryotherapy over a 10-year period at Women's Hospital LAC + USC Medical Center were reviewed. Although the initial features of the cervical intraepithelial neoplasia allowed for outpatient cryotherapy, the features of these failures did not (unsatisfactory colposcopy or CIN in the endocervical curettings). Eleven percent of these patients had stromal invasion on cone biopsy that was not suspected clinically. Patients presenting with cervical intraepithelial neoplasia following cryotherapy may, in fact, have progressive disease (i.e., stromal invasion) that is inapparent clinically. Hence, surgical excision should be considered in these circumstances.
