Uterine Malignancy: Pathological Pattern and Changing Incidence in a Teaching Hospital in Jeddah, Saudi Arabia

Introduction: Uterine carcinoma is one of the most common malignancies affecting women globally. It is the second most common gynecologic malignancy in impoverished countries and the most common in industrialized countries. Objective: To describe the histopathological patterns of uterine malignancies and their changing incidence at King Abdulaziz University Hospital from 2011 to 2020. Methodology: A retrospective study was conducted to analyze female patient record files from 2011 to 2020 who underwent uterine resection surgery at the King Abdulaziz University Hospital, Jeddah, Saudi Arabia. Results: A total of 263 patients were included. The age ranged from 30 to 95 years old; median age of 61 years. The majority (71%) presented with the complaint of abnormal uterine bleeding. The most common histopathological diagnosis was endometrioid carcinoma (70%), followed by serous carcinoma (13.7%). The lowest reported uterine cancer diagnoses were in the year of 2011 with (<5%) of the cases while the highest were in the year of 2020. These findings demonstrate a variable incidence of endometrial carcinomas in the study population over the study period. With trends of an increasing incidence till 2018 followed by a marginal reduction in 2019 and 2020. Conclusion: The most frequent histopathological diagnosis of uterine cancer was endometrioid carcinoma followed by serous carcinoma, (70%) and (13.7%) respectively. Type 1 endometrial carcinoma was prevalent throughout the decade surpassing the type-2 endometrial carcinoma. The trend also shows a steady increase in the frequency of uterine cancer which is alarming and prompts further research to determine factors associated with and molecular classification of reported uterine cancer cases.
