Prognostic factors in surgically treated stage IB–IIB carcinoma of the cervix with negative lymph nodes

Comerci G, Bolger BS, Flannelly G, Maini M, de Barros Lopes A, Monaghan JM. Prognostic factors in surgically treated stage IB–IIB carcinoma of the cervix with negative lymph nodes. Int J Gynecol Cancer 1998; 8: 23–26.
Two hundred and seventy-five females with stage IB–IIB negative lymph node cervical cancer, treated between January 1988 and December 1994 by radical hysterectomy and pelvic lymph node dissection, form the basis of this analysis. The clinical records were reviewed for all patients including histopathology, clinical features at presentation, and follow-up. Tumors were re-staged according to the 1995 FIGO classification.
Median follow-up was 55 months and 85.8% were followed for longer than two years. There were 21 recurrences, 12 of which were true central recurrence (disease-free survival at 5 years: 91.66%). Fifteen of 25 deaths were due to cervical cancer (crude survival at 5 years: 93.27%). In univariate log-rank analysis, stage ( P = 0.005), tumor size ( P = 0.0002), and lymph-vascular space involvement (LVSI) ( P = 0.01) appeared to be statistically significant factors for tumor recurrence. Other factors including age, histology type, differentiation, adjacent cervical intraepithelial neoplasia or cervical glandular intraepithelial neoplasia, and presence of intraepithelial disease at resection margin were not found to be statistically significant. In multivariate analysis (Cox regression) tumor size ( P = 0.02) and LVSI ( P = 0.03) were the only independent variables. In the presence of negative lymph nodes and complete surgical excision, tumor size and LVSI are important predictors of local recurrence.
