Abstract
Background and objectives This study aimed to investigate the impact of intermediate-risk factors (IRFs) on the prognosis of stage I-II cervical cancer (CC) patients, and evaluate the necessity of adjuvant treatment based on investigation. Methods Medical records of 976 negative high-risk factors’ CC patients were retrospectively reviewed. Clinicopathologic characteristics and adjuctive therapy were analyzed using Kaplan–Meier analysis and log-rank tests to identify significant factors. The multivariate Cox proportional hazards regression analysis was performed to identify the independent prognostic factors. Results For patients with none, single and multiple IRFs, the 3-year recurrence-free survival rates were 97.8%, 86.3%, and 68.0% respectively (p < 0.001), and 3-year overall survival rates were 99.3%, 93.6% and 79.0% respectively (p < 0.001). Multivariate analysis showed histological type, differentiation grade, the number of IRFs and adjuvant therapy were independent prognostic factors. Conclusions The number of IRFs was demonstrated with higher predictive efficacy on survival of CC than individual IRF. Patients with multiple IRFs had significantly worse survival outcomes than patients with none or one. Different adjuvant treatment plans should be formulated based on the number of present IRFs. The prognostic management of patients with multiple IRFs should be pay more attention.
