Objective: This study aimed to evaluate the effect of waiting time from diagnosis to initiation of definitive concurrent chemoradiation (CCRT) on overall survival in patients with cervical cancer.
Methods: Patients with cervical cancer who had definitive CCRT between 2000 and 2017 were retrospectively reviewed. Time from pathological diagnosis to definitive CCRT was analyzed both as a continuous variable (per day) and as a categorical variable in 2 groups (Group 1 median, Group 2 > median). Patients with waiting time more than 60 days were excluded. Associations between waiting time, patients baseline characteristics, and survivals were analyzed using the Cox proportional-hazards model.
Results: The median waiting time was 14 days (0-60). There were differences between Group 1 and Group 2 in age and type of chemotherapy. However, no significant difference was found in the FIGO stage, cell type, and the number of cycles of chemotherapy received during CCRT. Longer waiting time was associated with poorer overall survival on the Kaplan-Meir curve (Group 1 vs. Group 2, P = .042). On multivariate analysis, intervals as either a continuous variable (HR; 1. 023, 95% CI; 1.0061.040, P = .007) or a categorical variable (HR; 1.513, 95% CI; 1.0732.134, P = .018), FIGO stage, cell type, and the number of cycles of chemotherapy received during CCRT were significant independent prognostic factors for overall survival.
Conclusion: Longer waiting time from pathological diagnosis to definitive CCRT was associated with worse overall survival. Our findings suggest that stakeholders in healthcare, including physicians and policymakers, should make an effort to minimize waiting time by rethinking factors involved in waiting time, such as referral time and time from decision making to treatment.
