Prognostic factors in endometrial carcinoma

Area of Science:

• Gynecologic Oncology
• Pathology
• Cancer Research

Background:

• Endometrial carcinoma is Singapore's third most common female genital tract cancer.
• Despite early detection, significant mortality persists, necessitating risk stratification.
• Identifying patients at high risk of relapse is essential for tailored treatment strategies.

Purpose of the Study:

• To evaluate the prognostic significance of various clinical, histologic, and molecular factors in endometrial carcinoma.
• To determine if novel markers add significant prognostic information beyond routine evaluation.
• To improve early identification of patients requiring additional treatment for endometrial cancer.

Main Methods:

• Review of clinical history, gross uterine examination, and routine microscopy.
• Analysis of established prognostic factors: age, stage, histologic type (serous, clear cell), grade, lympho-vascular invasion.
• Investigation of potential markers: tumor size, peritoneal cytology, receptor status (ER/PR), p53, DNA ploidy, S-phase fraction, HER-2/neu (c-erbB-2).

Main Results:

• Routine factors like age, stage, histologic type, grade, and lympho-vascular invasion are key prognostic indicators.
• Tumor size, location, and peritoneal cytology have less certain prognostic value.
• Emerging markers (ER/PR, p53, ploidy, HER-2/neu) show potential independent prognostic significance in multivariate analysis.

Conclusions:

• Routine clinicopathological factors provide essential information for predicting endometrial carcinoma relapse.
• The added prognostic value of newer molecular markers over routine evaluation requires further investigation.
• Accurate risk stratification is vital for optimizing treatment decisions in endometrial carcinoma management.
