[Endocrine-active tumors of the ovary]

Area of Science:

• Gynecologic Oncology
• Endocrinology
• Pathology

Context:

• Ovarian tumors represent a diverse group, with a small subset exhibiting hormonal activity.
• Tumors of the gonadal stroma are the most common source of hormonally active ovarian neoplasms, accounting for less than 5% of all ovarian tumors.
• Approximately two-thirds of gonadal stromal tumors produce steroid hormones, leading to significant clinical implications.

Purpose:

• To elucidate the characteristics and clinical significance of hormonally active ovarian tumors, particularly those arising from the gonadal stroma.
• To describe the pathological hormone secretion patterns and their effects on target organs.
• To differentiate between primary hormone-secreting tumors and other ovarian tumors that may induce hormonal activity.

Summary:

• Hormonally active ovarian tumors are predominantly tumors of the gonadal stroma, which constitute less than 5% of all ovarian neoplasms.
• About 66% of these gonadal stromal tumors secrete steroid hormones (estrogenic or androgenic), leading to specific clinical manifestations dependent on hormone levels and patient age.
• While gonadal stromal tumors are the primary focus, other ovarian tumors can also exhibit hormonal activity through stimulation of adjacent non-neoplastic ovarian stromal cells.

Impact:

• Understanding the hormonal activity of ovarian tumors is crucial for accurate diagnosis and patient management.
• The clinical presentation of these tumors is directly linked to the type and amount of hormones secreted, necessitating a thorough endocrine evaluation.
• Gonadal stromal tumors possess malignant potential, ranging from borderline to invasive types, highlighting the importance of early detection and treatment.
