What is Peritoneal Metastasis Surgery (CRS)?
Peritoneal Metastasis Surgery, also known as Cytoreductive Surgery (CRS), is a highly specialized oncologic procedure designed to remove cancer that has spread to the peritoneum — the lining of the abdominal cavity.
These metastases often result from cancers such as:
-
Colon and rectal cancer
-
Appendix cancer (including mucinous tumors)
-
Ovarian cancer
-
Gastric cancer
-
Peritoneal mesothelioma
The goal of CRS is to remove all visible tumor deposits from abdominal organs and peritoneal surfaces.
Why is Cytoreductive Surgery Needed?
CRS is recommended for patients who have:
-
Peritoneal metastases (peritoneal carcinomatosis)
-
Tumor spread within the abdomen without distant organ involvement
-
Pseudomyxoma Peritonei (PMP)
-
Recurrent abdominal cancers causing ascites or discomfort
-
Appendix or colon cancer with mucin-producing tumors
-
Ovarian cancer with peritoneal spread
CRS can significantly improve survival when performed at experienced centers.
