Hyperthermic Intraperitoneal Chemotherapy (HIPEC): What You Need to Know
Request Call Back
Overview
Hyperthermic Intraperitoneal Chemotherapy (HIPEC), also known as heated chemotherapy, is an innovative treatment method for advanced abdominal cancers. Unlike standard chemotherapy, which circulates throughout the entire body, HIPEC delivers chemotherapy directly into the abdominal cavity after surgical removal of visible tumors. By combining surgery with heated chemotherapy drugs, this approach targets residual cancer cells that cannot be seen or safely removed during surgery.
HIPEC is most commonly used for cancers that spread within the abdominal lining (peritoneum), including stomach cancer, colorectal cancer, ovarian cancer, and appendix cancer. At MedicalPoint Hospital, we integrate advanced surgical expertise with HIPEC technology to provide patients with more effective treatment options, aiming to improve survival rates and enhance quality of life.
What Is HIPEC?
HIPEC is a specialized procedure performed immediately after cytoreductive surgery (CRS), where visible tumors in the abdomen are surgically removed. Once this step is complete, the abdominal cavity is filled with a heated chemotherapy solution (around 42°C / 107.6°F) for approximately 60–90 minutes.
The heated solution has two important effects:
- Direct tumor exposure: The chemotherapy directly bathes the cancer cells, increasing drug concentration in the abdominal cavity without affecting the whole body as much as standard chemotherapy.
- Heat-enhanced effectiveness: Heat makes cancer cells more sensitive to chemotherapy, improves drug penetration into tissues, and damages cancer cell proteins, making them less able to repair themselves.
This dual mechanism allows HIPEC to attack residual cancer cells more effectively than conventional systemic chemotherapy.
Why Is HIPEC Used?
HIPEC is recommended for cancers that are prone to spreading within the abdominal lining, such as:
- Colorectal cancer (with peritoneal spread)
- Ovarian cancer (advanced or recurrent cases)
- Stomach cancer with peritoneal involvement
- Appendix cancer, including pseudomyxoma peritonei
- Primary peritoneal cancer
These cancers often develop microscopic tumor deposits in the peritoneum, which are difficult to remove completely with surgery alone. HIPEC addresses this challenge by targeting the peritoneal cavity directly.
How Does HIPEC Differ from Standard Chemotherapy?
Traditional chemotherapy is delivered through the bloodstream and affects the entire body. While effective in many cancers, it often causes systemic side effects such as hair loss, immune suppression, and fatigue.
HIPEC, however:
- Works locally in the abdominal cavity.
- Provides higher drug concentration directly to the cancer site.
- Limits systemic exposure, which may reduce overall side effects.
- Uses heat to boost the cancer-killing effects of chemotherapy.
This makes HIPEC particularly valuable for patients whose cancers have spread locally within the abdomen but not extensively to other organs.
History and Development of HIPEC
HIPEC was first introduced in the 1980s by Dr. Paul Sugarbaker, who demonstrated that combining cytoreductive surgery with heated chemotherapy could significantly improve outcomes for patients with peritoneal cancers. Since then, clinical research and technological advances have refined the procedure. Today, HIPEC is performed in specialized cancer centers worldwide, including MedicalPoint Hospital, where modern oncology practices integrate HIPEC into comprehensive cancer care.
How Is HIPEC Performed?
The procedure has two main steps:
- Cytoreductive Surgery (CRS) – Surgeons remove visible tumors from the abdominal cavity. This may involve partial removal of affected organs or tissues.
- HIPEC Treatment – After tumor removal, the abdominal cavity is filled with heated chemotherapy drugs. Pumps circulate the drug solution for about 60–90 minutes, ensuring even distribution.
Common Drugs Used in HIPEC:
- Mitomycin C – Prevents DNA replication in cancer cells.
- Cisplatin – Binds to DNA, triggering cell death.
- Doxorubicin – Blocks DNA replication and generates free radicals that damage cancer cells.
The combination of chemotherapy and heat enhances cancer cell destruction while sparing most healthy tissues.
Benefits of HIPEC
- Direct delivery of chemotherapy to the cancer site.
- Enhanced effectiveness due to heat.
- Potentially fewer systemic side effects compared to intravenous chemotherapy.
- Increased survival rates in selected patients with advanced abdominal cancers.
- Improved quality of life when cancer-related symptoms such as ascites (fluid buildup) are reduced.
Risks and Side Effects of HIPEC
- Infection – Due to the invasive nature of surgery.
- Kidney problems – Certain drugs like cisplatin can impair kidney function.
- Abdominal adhesions – Scar tissue may form, sometimes leading to bowel obstruction.
- Nausea and vomiting – A common chemotherapy side effect.
- Blood-related effects – Reduced production of blood cells may cause anemia, low white blood cell count, or increased bleeding risk.
- Fluid and electrolyte imbalances – From exposure to chemotherapy solution.
- Postoperative pain – As with most major abdominal surgeries.
Life After HIPEC
Recovery from HIPEC requires careful follow-up:
- Hospital stay – Usually 10–14 days, depending on patient recovery.
- Follow-up scans and tests – To monitor for recurrence.
- Nutritional support – Helps patients regain strength.
- Psychological care – Managing cancer treatment can be emotionally challenging, so counseling and support groups are often recommended.
Many patients experience improved quality of life after HIPEC, as symptoms such as abdominal pain, bloating, and fluid accumulation decrease.
Conclusion
HIPEC is a cutting-edge cancer treatment that combines surgery and heated chemotherapy to target abdominal cancers more effectively. It has proven especially valuable in colorectal, ovarian, gastric, and appendix cancers that have spread within the peritoneum.
At MedicalPoint Hospital, we are proud to offer HIPEC as part of our comprehensive oncology services. By combining advanced surgical expertise, innovative technology, and compassionate patient care, we aim to extend survival and improve quality of life for patients facing complex cancers.
