Abstract

Background: Endometrial cancer (EC) is the most common gynecological cancer in developed countries and a standard treatment of surgery should be performed as expediently as possible. Delay time to surgery and survival was debated. The aim of this investigation was to evaluate the effect of time-interval between diagnosis and surgery (TDS) in EC patients with regards to prognosis and mortality rates. Methods: This retrospective study was conducted between January 2009 and May 2021 at Bhumibol Adulyadej Hospital, Thailand. Subjects were EC cases who underwent primary surgery during the study period. Cases with partial treatment were disqualified from the study. Subjects who underwent surgery before and after 6 weeks were classified as early and delayed surgery groups. Baseline and clinical characteristics were collected and analyzed. Results: During the study period, 419 EC cases were recruited. The mean age of participants was 56.8 years. Two-thirds (338/491) of subjects were menopausal. Endometrioid histology (406/491) was the most common histology subtype. Five years disease free survival (DFS) of early and delayed surgery groups were comparable at a percentage of 82.5 and 83.0, respectively. Among advanced stage and non-endometrioid EC cases, the delayed surgery group had significantly shorter DFS than the early group. Advanced stage, high grade and positive lympho-vascular space invasion (LVSI) were independent factors for poor DFS. Predictive factors for mortality were advanced stage and tumor recurrence. Conclusion: The TDS was not a prognostic factor for disease recurrence or overall mortality. Time to surgery equal to or more than 6 weeks gave worse prognosis for DFS among advanced stage or non-endometrioid histology EC.
