Ovarian tumours: anatomohistopathological contribution to their interpretation

Area of Science:

• Gynecologic Oncology
• Epidemiology
• Pathology

Background:

• Ovarian tumors represent a significant health concern globally.
• Understanding local epidemiological patterns is crucial for targeted public health strategies.

Purpose of the Study:

• To present epidemiological and anatomopathological data on ovarian tumors in the Trieste province.
• To analyze incidence rates, age distribution, and histological types of ovarian neoplasms.

Main Methods:

• Retrospective analysis of 970 ovarian neoplasms diagnosed between 1969-1985.
• Data collected from the Institute of Pathological Anatomy and Histology, Trieste University.
• Calculation of crude and standardized incidence rates for benign and malignant ovarian tumors.

Main Results:

• Overall, 66.7% of ovarian tumors were benign and 33.3% were malignant.
• Crude incidence rates: 24.2/100,000 for benign and 12.1/100,000 for malignant tumors.
• Standardized incidence of malignant ovarian tumors was low (6.5/100,000) and stable over time. Malignant tumors were more prevalent in elderly women, while benign tumors affected all age groups.
• Epithelial tumors were the most frequent histological type for both benign (over 50%) and malignant (94.4%) ovarian neoplasms.

Conclusions:

• The incidence of malignant ovarian neoplasms in Trieste is low and has not increased over time.
• Histological type and age distribution vary significantly between benign and malignant ovarian tumors.
• Epidemiological data provide valuable insights into ovarian tumor patterns for public health planning.
