STAGE-I CERVICAL ADENOCARCINOMA - PROGNOSTIC EVALUATION OF SURGICALLY TREATED PATIENTS

In order to evaluate clinicopathologic determinants of recurrence in adenocarcinoma of the uterine cervix, a detailed retrospective chart review and complete pathology analysis were performed for 79 patients who had been treated by Type III radical hysterectomy between 1975 and 1988. All patients had clinical stage I disease; 77 had cervical diameters of 4 cm or less. Eleven patients (14%) developed recurrent disease with a median time to recurrence of 14 months (range, 7-51). Recurrence location was central in 5 patients, pelvic wall in 2, and distant in 4. Seven patients died of disease. Five-year actuarial survival was 89%. None of the clinical features examined as possible prognostic factors was predictive of recurrence, including patient age (P = 0.91), cervical diameter (P = 0.30), presence of pain (P = 0.53), presence of abnormal bleeding (P = 0.19), and history of oral contraceptive use (P = 0.58). However, univariate analysis showed lymph node spread (P = 0.008), lymph-vascular space invasion (P = 0.05), and increasing grade (P = 0.05) to be significant predictors of recurrence. Lymph-vascular space invasion remained significant when patients with positive nodes were excluded (P = 0.026). Depth of invasion >3 mm was associated with greater recurrence risk than depth ≤3 mm (P = 0.01). Number of mitoses (P = 0.10) was not significant. Multivariate analysis selected nodal positivity as the major prognostic parameter (P = 0.04). Further studies are needed to more clearly define the role of lymph-vascular space invasion, as an elevated risk ratio of 1.6 suggests an increased risk for recurrence. Patients whose pretreatment biopsies demonstrate obvious lymph-vascular space invasion might be considered for alternate treatment. © 1993 Academic Press, Inc.
