Prognostic factors in microinvasive cervical squamous cell cancer: long-term results.
We examined tumor-related pathologic factors and cone-related characteristics to identify parameters related to recurrence in microinvasive squamous cell carcinoma of the cervix treated with conization. This is a retrospective study on 67 consecutive cases of microinvasive carcinoma of the cervix [depth of invasion (DI) < 3 mm] treated with conization. The mean follow-up was 121 months (range 72-276 months). Four (6%) invasive recurrences were observed. Presence of lymphvascular space involvement (LVSI) was significantly related with recurrences (P < 0.05). The mean distance between tumor margin and apex of the cone (apical clearance) was 10.6 mm (range 5-22 mm), and the mean distance between lateral border of the cone and tumor margin (lateral clearance) was 6.5 mm (range 1.7-15 mm). We adopted cut-off values of 10 and 8 mm for apical and lateral clearances, respectively. We found a statistically significant difference between apical clearance and recurrence rate (P < 0.02). The LVSI was, other than DI, an important prognostic factor. Apical clearance was significantly correlated with recurrence. The cone-related characteristics, other than tumor-related pathologic factors, could help the decision concerning the definitive therapy for microinvasive carcinoma of the cervix.
