The prognostic significance of pelvic lymph node morphology in carcinoma of the uterine cervix.
Pelvic lymph nodes from 80 patients with primary invasive cervical cancer undergoing radical hysterectomy and pelvic lymphadenectomy were evaluated morphologically. Six to 25 (mean 14) lymph nodes from each patient were examined histologically and classified as follows: lymphocyte preominant, germinal center predominant, unstimulated, or lymphocyte depleted. Tumors were classified according to their primary cell type: large cell non-keratinizing, keratinizing squamous cell, small cell, and adenocarcinoma. There was no direct relationship between lymph node morphology and patient age, lesion size, or tumor cell type. A lymphocyte predominant nodal pattern was associated with a statistically significant decrease in lymph node metastases, and tumor recurrence, and an increase in patient survival. In contrast, patients with a lymphocyte depleted nodal pattern had a high incidence of metastatic disease and tumor recurrence, and a decreased survival. Patients with lymph nodes showing an unstimulated or germinal center predominant pattern had an intermediate incidence of nodal metastases and tumor recurrence. These findings suggest that regional lymph nodal morphology may be of prognostic significance in patients with invasive carcinoma of the uterine cervix.
