ABSTRACT
| Histomorphology and Epidemiological Pattern of Ovarian surface Epithelial Tumours in a Nigerian Tertiary Hospital - A Ten-Year Retrospective Analysis |
| Aliyu Salihu*, Usman Bello |
| Background: Ovarian cancer remains one of the most lethal gynecological malignancies worldwide, with the majority of these being ovarian surface epithelium tumours. Despite its importance, the paucity of information regarding long-term histomorphological and epidemiological characteristics of thes tumour pose a great concern in our environment. This study aimed to evaluate and document the histomorphological and epidemiological patterns of. Ovarian surface epithelial tumours in our settings. Materials/methods: A review of histologically confirmed ovarian surface epithelial tumors diagnosed between January 2011 and December 2020 was conducted. Formalin-fixed, paraffin-embedded tissue blocks were retrieved, and hematoxylin and eosin-stained slides were reevaluated. Tumors were classified according to world health organization classification. Patient demographic data was also collected and analyzed using descriptive statistics. Results: There were 753 ovarian tumors out of which 218 (29%) were surface epithelial tumors. Patient ages ranged from 17 to 72 years, with the highest incidence in the 41–50 age group. Serous tumors were most common (55%), followed by mucinous (33%) and Brenner tumors (10%). Malignant tumors predominated (53%), with serous carcinoma being the most common subtype (61% of malignancies). Benign tumors accounted for 36% and borderline tumors for 11% of cases. Notably, mucinous tumors were more common among benign tumours, hence contrasting with global trends. Conclusions: The most common ovarian surface epithelial neoplasm in our setting was serous cyst adenocarcinoma while muscinouscystadenoma was the most predominant benign lesion. The tumours show biphasic peak of incidence. Regional differences in tumor subtype prevalence highlight the importance of localized data in guiding diagnostic and treatment options for ovarian cancer. |
