BackgroundSurvival for patients with early stage cervical cancer without any high-risk factors treated with radical hysterectomy is excellent. However, there are few data on the survival outcomes for low-risk and intermediate-risk early stage cervical cancer patients.ObjectiveTo determine survival outcomes and prognostic factors of low-risk and intermediate-risk stage IB1 cervical cancer patients.MethodsStage IB1 cervical cancer patients with radical hysterectomy and pelvic lymphadenectomy were retrospectively reviewed. Patients with positive pelvic nodes, parametrial involvement, and positive margin who are classified as high-risk patients were excluded. Patients with squamous cell carcinoma or grade 1–2 adenocarcinoma, tumor size less than 2 cm, no lymphovascular space invasion (LVSI), and depth of stromal invasion (DSI) less than 10 mm were defined as low-risk patients. Survival was evaluated using the Kaplan–Meier method and compared by the log-rank test. Multivariate analysis was performed using Cox proportional-hazards regression.ResultsThere were 82 (42.3%) low-risk patients and 112 (57.7%) intermediate-risk patients. More patients in intermediate risk received adjuvant treatment (3.6% and 14.3%, P = 0.07). Three (3.6%) low-risk patients and 18 (16.1%) intermediate-risk patients had recurrent disease (P = 0.004). At median follow-up of 86 months, 1.2% of low-risk patients and 8.9% of intermediate-risk had cancer-related deaths (P = 0.02). Low-risk patients had significantly better 5-year disease-free survival (98.2% vs 91.1%, P = 0.01) and estimated 5-year overall survival (98.5% vs 91.1%, P = 0.01). DSI more than 10 mm and presence of LVSI were significantly associated with recurrence. However, LVSI was an independent prognostic factor.ConclusionStage IB1 cervical cancer patients had excellent survival. Low-risk patients had significantly better survival. Presence of LVSI was an independent prognostic factor.
