Carcinoma-in-situ of the cerivix treated with colposcopy guided epithelial conization. Report of a 4-7 year follow-up study.

Twenty-five patients with the diagnosis of carcinoma-in-situ (CIS) of the cervix were treated with colposcopy guided epithelial conization. During the follow-up study of 4-7 years' duration, there was no recurrence of CIS in 20 of the 25 patients. Between 6 and 12 months after conization, 3 patients showed recurrence of CIS. Two of these patients were treated with further epithelial conization with no evidence of further recurrence 4 years after the second treatment. The third patient refused to accept further epithelial conization and modified radical hysterectomy was done without any evidence of residual tumour in the hysterectomy specimen. One patient showed stromal invasion in both colposcopically guided biopsy and bone biopsy. Modified radical hysterectomy specimen showed remnants of stromal invasion. One patient with Class IV smear failed to show any atypical transformation zone and cervicitis was proven on colposcopy guided biopsy following treatment with Flagyl. For two of the 25 patients, cytology was Class II and therefore failed to diagnose the pre-malignant condition; but colposcopy showed a grade 3 atypical transformation zone and the presence of CIS was confirmed histologically. Simultaneous use of cytology, colposcopy and colposcopically guided biopsy confirmed the diagnosis of CIS in all cases. The authors recommend colposcopically guided epithelial conization in younger patients, provided the malignant lesion is strictly intra-epithelial, and limited to the ectocervix. Routine follow-up with the aid of cyto-colposcopy remains the key factor in this schedule of therapy.[1]
