Peritoneal metastases are difficult to treat because standard IV chemotherapy often cannot reach tumors inside the abdomen effectively. This review explores NIPS, an approach that combines intravenous chemotherapy with repeated chemotherapy delivered directly into the abdominal cavity. Early research—especially in gastric cancer—suggests this strategy may improve disease control, increase eligibility for surgery, and help some patients live longer.

International experts are working to make treatment for advanced ovarian cancer more personalized. This special issue of PSOGI World News highlights new evidence supporting careful patient selection for cytoreductive surgery and HIPEC, the growing role of minimally invasive surgery, and how emerging technologies like artificial intelligence may improve treatment planning and outcomes in the future.

The CHARLIE-2 trial is the first randomized study to directly compare HIPEC and PIPAC, two methods of delivering chemotherapy directly into the abdomen for patients with peritoneal carcinomatosis. Researchers will evaluate safety, quality of life, treatment response, and cost to determine which approach may provide the greatest benefit for patients who are not candidates for complete tumor-removal surgery.

Genetic mutations may determine which ovarian cancer patients do better following HIPEC

Pancreatic cancer that has spread to the lining of the abdomen (called the peritoneum) is often difficult to treat and is associated with poor outcomes. Standard treatment typically involves chemotherapy, but survival rates remain low. Researchers conducted a systematic review to examine whether a treatment approach called cytoreductive surgery (CRS) combined with hyperthermic intraperitoneal chemotherapy (HIPEC) may improve outcomes for some patients with pancreatic cance

Peritoneal metastases occur when cancer spreads to the lining of the abdomen (the peritoneum). This can happen with cancers such as colorectal, appendiceal, gastric (stomach), ovarian cancers, and peritoneal mesothelioma. Historically, patients with peritoneal metastases had very limited treatment options and poor survival. Researchers reviewed published studies to better understand how a treatment called cytoreductive surgery combined with HIPEC affected survival.

In the fight against advanced abdominal cancers, we stand behind a powerful treatment that is changing outcomes and saving lives: CRS/HIPEC (Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy). This life-extending procedure offers renewed hope for patients with complex peritoneal surface malignancies. And yet far too many never hear about it in time. The Abdominal Cancers Alliance is here to support patients in their fight.

This research study explored outcomes for people with colorectal cancer that had spread to two places at the same time: the lining of the abdomen (called the peritoneum), and the liver.
