Uterine Endometrial Carcinoma: 10 Years’ Experience with Long-Term Follow-Up at a Single Korean Institution

Aim: To evaluate prognostic factors in Korean patients with endometrial cancer. Methods: A retrospective analysis was conducted on 248 patients who were staged surgically at the Samsung Medical Center between 1995 and 2004. Survival data were analyzed using Kaplan-Meier estimates, and multivariate analysis was performed using the Cox regression method. Results: The median age was 51 years (range 21–75), which was younger than in previous studies in Western patients, and the age of 50 years was the cutoff to predict survival. More than half (55.6%) were normal weight or underweight (BMI <25). Multivariate analysis revealed that age, Fédération Internationale de Gynécologie et d’Obstétrique (FIGO) stage, and histopathology were independent predictors of disease-free survival, and FIGO stage and p53 mutation were independent prognostic factors for disease-specific survival (DSS). The 5-year DSS for patients with stage I, II, III and IV disease was 95.6, 93.8, 69.8 and 50%, respectively. The 5-year DSS rate for patients with a p53 mutation was 84.4%, compared with 97.1% for patients without. Conclusions: Korean patients with endometrial cancer were younger and had a lower BMI than previously reported. Furthermore, age greater than 50 years was predictive of a poor outcome. Age, FIGO stage, histopathology and a p53 mutation were independent prognostic factors for survival.
