Abstract

OBJECTIVE:

The aim of this study was to determine predictive factors for post-cone residual disease in subsequent hysterectomy for CIN III.

METHODS:

From June 1994 to June 1999, 120 patients with CIN III who received hysterectomy within 6 months of conization regardless of marginal status were identified from 1450 conization cases. The demographic features and pathologic parameters were analyzed for the predictive rate of post-cone residual disease.

RESULTS:

Age >==50 years and parity >==5 were significant factors associated with residual disease. The incidence of residual disease was 56.5 and 29. 3% in patients >==50 and <50 years, respectively, and 61.8 and 36.0% in patients with parity >==5 and <5. Post-cone endocervical curettage (ECC) and multiple-quadrant disease were the only pathologic predictive factors identified. The incidence of residual disease was 64.6 and 29.2% in patients with positive ECC and negative ECC, respectively, and 48.4 and 25.9% in patient with multiple-quadrant disease and one- or two-quadrant disease. Other pathologic parameters, including endocervical margins, ectocervical margins, endocervical gland involvement, and depth of conization, were not predictive of residual disease. When ECC was combined individually with age, endocervical margins, or multiple-quadrant disease, there was no increase of positive predictive rate.

CONCLUSIONS:

(1) Age 50 years or more and parity >==5 were two demographic features that predicted post-cone residual disease. (2) ECC and multiple-quadrant disease were the only pathologic parameters that predicted post-cone residual disease. (3) With the appropriate application of the predictive factors, post-cone hysterectomy may be further decreased.
