Abstract

The influence of time to chemotherapy (TTC) on recurrence and survival among epithelial ovarian cancer (EOC) patients still remains unknown. This single center retrospective cohort study was conducted on 489 EOC patients who underwent surgery followed by taxane- plus platinum-based chemotherapy in the Shengjing Hospital of China Medical University between 2011 and 2015. The Multivariate cox proportional regression models were used to calculate hazard ratios (HRs) and 95% confidence intervals (CIs) for progression-free survival (PFS) and overall survival (OS) after adjustment for potential confounders. The median follow-up duration was 2.97 years (inter-quartile range from 2.11 to 4.13 years). The recurrence and mortality rate of the all patients was 50.9% (249/489) and 43.6% (213/489), respectively. Having comorbidity, residual disease, ascites, and advanced FIGO stage (III-IV) was associated worse PFS and OS of EOC patients. Compared to TTC less than 14 days, delayed TTC (more than 28 days) was associated with a worse PFS (HR=1.36; 95%CI: 0.96-1.92) and OS (HR=1.38; 95%CI: 0.95-2.00). Notably, in EOC patients with advanced stage, delayed TTC (more than 28 days) was associated with worse PFS (HR=1.51; 95%CI: 1.02-2.24) and OS (HR=1.53; 95%CI: 1.01-2.32) when comparing to TTC less than 14 days. In conclusion, delayed TTC was associated with higher rates of EOC recurrence and survival among these patients with advanced stage. The findings of the present study may provide evidence for gynecologist as well as these ovarian cancer patients to make further decision for the treatment.
