peritoneal carcinomatosis
Pronunciation: pair-i-tuh-NEE-uhl kar-suh-noh-muh-TOH-sis
Advanced cancer with widespread metastatic implants throughout the peritoneal cavity lining.
Full Definition
Peritoneal carcinomatosis represents advanced-stage disease where malignant cells have seeded throughout the peritoneal surfaces, forming multiple tumor deposits. This condition commonly arises from gastric, colorectal, ovarian, and pancreatic primary tumors through transcoelomic spread. The extent is often quantified using the Peritoneal Carcinomatosis Index (PCI) for surgical planning. Treatment approaches may include cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) in selected cases. Editorial care is needed to distinguish from primary peritoneal malignancy.
Usage
Usage note: Use singular form; avoid redundant phrases like 'peritoneal carcinomatosis deposits.'
