Continuous Hyperthermic Peritoneal Perfusion

What Continuous Hyperthermic Peritoneal Perfusion Means in Everyday Medical Language

Continuous Hyperthermic Peritoneal Perfusion, often called CHPP or HIPEC, is a treatment used during surgery for certain cancers that have spread inside the abdomen. After surgeons remove as much visible tumor as they can, a warm liquid containing chemotherapy drugs is circulated inside the belly. This liquid bathes the lining of the abdomen, called the peritoneum, to help kill any cancer cells that remain after surgery. The heat makes the chemotherapy drugs work better at destroying these leftover cells.

Why CHPP Can Matter in Cancer Care

Cancers that spread to the peritoneum can be hard to treat with standard chemotherapy given through the bloodstream. CHPP delivers chemotherapy directly to the area where cancer cells remain after surgery, increasing the chance of killing them. By combining surgery with this heated chemotherapy bath, doctors aim to improve control of the cancer inside the abdomen and reduce the chance it will come back in that area. This approach is often considered when imaging and surgery show cancer spread limited to the abdominal lining.

What Patients Might See or Hear About CHPP

Patients may hear the terms CHPP, HIPEC, or hyperthermic intraperitoneal chemotherapy when discussing treatment options for abdominal cancers such as ovarian or colorectal cancer that have spread within the belly. The procedure usually happens during a longer surgery, right after tumor removal and before closing the incision. Patients might be told that CHPP involves circulating a warm chemotherapy solution inside the abdomen for a set time. Recovery may take longer than surgery alone. It is important to understand that CHPP is part of a combined treatment plan and does not guarantee all cancer cells will be gone.

Where the Term Might Appear

The term CHPP can appear in treatment plans, surgical reports, or clinical trial descriptions related to abdominal cancers. It is not a diagnostic test or a routine chemotherapy method given outside surgery. Instead, it is a specialized treatment step used during surgery to target cancer cells in the peritoneal cavity.

What CHPP Does Not Automatically Mean

Hearing the term CHPP does not mean the cancer is cured or that this is the only treatment option. CHPP is not a cure by itself and is not suitable for all patients or all types of cancer. It is typically considered only when cancer has spread within the peritoneal lining but not to distant organs. It is also not a standalone treatment but part of a combined approach with surgery and chemotherapy.

Common Questions to Ask Your Care Team

If CHPP is mentioned as part of your care, it can help to ask your doctors how this treatment fits with other therapies, what to expect during and after surgery, and what the possible benefits and risks are. Understanding the goals of CHPP and how it may affect recovery can help you make informed decisions about your treatment.

How to Read the Term in Context

Reading about CHPP alone can be confusing. It is best understood as part of a broader treatment plan involving surgery and chemotherapy for cancers that have spread inside the abdomen. Each person’s situation is unique, so treatment decisions depend on many factors.

Safety and Next Steps

This information is educational and does not replace personalized medical advice. If you or a loved one is facing a cancer diagnosis where CHPP is mentioned, the next sensible step is to discuss with your oncology team what this treatment means for your specific case. They can explain how CHPP might fit into your care, what to expect, and help you weigh the potential benefits and risks.
