serous carcinoma
Aggressive type of gynecologic cancer that can arise from ovary, fallopian tube, or peritoneum, often presenting at advanced stages.
Full Definition
Serous carcinoma is a highly aggressive form of adenocarcinoma that can arise from the ovary, fallopian tube, or primary peritoneum, collectively referred to as high-grade serous carcinoma (HGSC) when discussing the most common variant. This cancer type is characterized by rapid growth and early metastatic spread, often presenting with advanced-stage disease and peritoneal carcinomatosis. Serous carcinomas are frequently associated with BRCA mutations and homologous recombination deficiency, making them potentially responsive to PARP inhibitor therapy. The tumor typically shows papillary architecture and high-grade nuclear features. Treatment usually involves aggressive cytoreductive surgery followed by platinum-based chemotherapy, though prognosis remains challenging due to the advanced stage at presentation in most cases.
Usage
Usage note: Specify the grade (high-grade vs low-grade) and site of origin when documenting serous carcinoma.
