Impact of the Ratio of Metastatic to Examined Lymph Nodes on the Survival of Early-Stage Cervical Cancer Patients

Background: The aim of the study was to determine the impact of the ratio of metastatic to examined lymph nodes (LN) on the survival of early-stage cervical cancer patients. Methods: A retrospective review was performed of all patients undergoing primary radical hysterectomy and pelvicparaaortic lymphadenectomy for stage I–II cervical cancer at the Ankara Oncology Hospital from 1995 to 2000. Survival was determined by Kaplan-Meier method and differences were assessed by log-rank test. Results: A total of 2,085 LN were examined. Nodal metastasis was found in 22.1% of the patients. Patients with zero involved LN had a 5-year survival of 89.19%, while patients with 1 positive LN and > 1 positive LNs had a 5-year survival of 100 and 76.92%, respectively. The difference in survival among these three groups was not statistically significant. The 5-year survival rates according to the metastatic/examined LN ratio (LNR) were 75, 90, and 89.19% in the groups of patients with LNR >10, 1–10, and 0%, respectively. The difference in survival among these three groups was not statistically significant. Conclusions: This factor might be helpful for a better prognostic discrimination of patients with metastatic LN. The stratification of node-positive cervical cancer for prognostic and treatment purposes warrants further investigation.
