peritoneal carcinomatosis
Pronunciation: pair-ih-toh-NEE-al kar-sin-oh-mah-TOH-sis
Widespread dissemination of cancer throughout the peritoneal cavity, commonly seen in advanced ovarian cancer.
Full Definition
Peritoneal carcinomatosis refers to the extensive spread of malignant cells throughout the peritoneal cavity, involving the peritoneal surfaces that line the abdomen and pelvis. This condition is most commonly associated with advanced ovarian cancer, but can also result from gastric, colorectal, or primary peritoneal cancers. The cancer cells implant and grow on peritoneal surfaces, often causing ascites, bowel obstruction, and other complications. Treatment typically involves cytoreductive surgery combined with chemotherapy, and in some cases, hyperthermic intraperitoneal chemotherapy (HIPEC).
Usage
Usage note: Not to be confused with peritonitis (infection) or simple ascites (fluid accumulation).
