What Hyperthermic Intraperitoneal Chemotherapy Means

Hyperthermic Intraperitoneal Chemotherapy, often called HIPEC or Continuous Hyperthermic Peritoneal Perfusion (CHPP), is a treatment given during surgery for certain cancers that have spread to the peritoneum, the thin lining inside the abdomen. After surgeons remove as much visible tumor as possible, a warm liquid containing chemotherapy drugs is circulated inside the abdominal cavity. This heated chemotherapy bathes the lining of the abdomen to help kill any remaining cancer cells that are too small to see or remove by surgery alone. The warmth helps the chemotherapy drugs work better at destroying these leftover cells.

Why HIPEC Can Matter in Cancer Care

Cancers that spread to the peritoneum can be difficult to treat with standard chemotherapy given through the bloodstream. HIPEC 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 treatment, 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 HIPEC

Patients may hear the terms HIPEC, CHPP, 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 HIPEC involves circulating a warm chemotherapy solution inside the abdomen for a set time, often several hours. Recovery may take longer than surgery alone. It is important to understand that HIPEC is part of a combined treatment plan and does not guarantee all cancer cells will be gone.

Where the Term Might Appear

The term HIPEC 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 HIPEC Does Not Automatically Mean

Hearing the term HIPEC does not mean the cancer is cured or that this is the only treatment option. HIPEC 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 HIPEC 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 HIPEC and how it may affect recovery can help you make informed decisions about your treatment.

How to Read the Term in Context

Reading about HIPEC 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. If you see this term in a report or plan, ask your care team what it means for your specific case.

Safety and Next Steps

This information is educational and does not decide what is safe or appropriate for any individual. If you or a loved one is facing a cancer diagnosis involving the peritoneum, asking your care team about HIPEC can be a good next step. They can explain if this treatment is an option, what it involves, and how it fits with other therapies.
