Ovarian Tumors (Serous Carcinoma)

Overview


Plain-Language Overview

Ovarian tumors (serous carcinoma) are a type of cancer that starts in the ovaries, which are part of the female reproductive system. These tumors develop from the cells lining the ovary and can grow and spread to other parts of the body. The main health impact is due to the tumor's ability to invade nearby tissues and organs, causing symptoms like abdominal pain, bloating, and changes in bowel habits. Early stages may have no symptoms, making detection difficult. This cancer can affect fertility and overall health if not treated promptly. Diagnosis often involves imaging and tissue sampling to confirm the presence of cancer cells. Treatment usually requires surgery and chemotherapy to control the disease.

Clinical Definition

Ovarian tumors (serous carcinoma) are malignant epithelial neoplasms arising from the ovarian surface epithelium or fallopian tube epithelium, characterized by serous (fluid-producing) differentiation. They are the most common subtype of epithelial ovarian cancers and are classified into low-grade and high-grade based on histopathology and molecular features. High-grade serous carcinoma is associated with frequent mutations in the TP53 gene and often presents at an advanced stage with peritoneal spread. These tumors are clinically significant due to their aggressive behavior, poor prognosis, and high mortality rate among gynecologic malignancies. They typically produce elevated levels of the tumor marker CA-125. The pathogenesis involves genetic alterations leading to uncontrolled cell proliferation and resistance to apoptosis. Early detection is challenging due to nonspecific symptoms and lack of effective screening.
