Abstract

Background: This investigation delineated the survival rates and transitional probability trends of patients with endometrial cancer. This information is pivotal for optimizing patient management and counseling strategies. Methods: We conducted a retrospective cohort analysis of patients diagnosed with stage I or II endometrial cancer between November 2006 and October 2012 and those diagnosed with stage III or IV endometrial cancer between January 2012 and May 2017 at Siriraj Hospital, Bangkok, Thailand. Our examination included baseline demographics, clinical characteristics, and adjuvant therapy data. Survival rates and transitional probabilities were assessed using the Kaplan–Meier method for survival curve construction and Markov models, respectively. Results: After exclusions, 229 individuals with early-stage endometrial cancer and 119 with advanced-stage histologically verified endometrial cancer were included in the final cohort. Throughout a median follow-up duration of 12.8 years, the 5-year overall survival rates were 89.05% for the early-stage cohort and 50.42% for the advanced-stage cohort. The transitional probability analysis revealed an elevated likelihood of achieving a curative state in early-stage patients, contrasting with a greater propensity for disease progression or distant metastasis in advanced-stage patients. Conclusions: The findings from this study offer critical insights into the overall survival rates and transitional probabilities of endometrial cancer patients. These insights underscore the importance of strategies focused on preventing recurrence and enhancing treatment. Moreover, the results serve as a cornerstone for clinicians in devising individualized treatment plans and facilitating cost-effective analyses in the context of endometrial cancer care.
