HIPEC Surgery: Advanced Treatment for Abdominal Cancers

What is HIPEC Surgery?

HIPEC (Hyperthermic Intraperitoneal Chemotherapy) is an advanced cancer treatment used for certain abdominal cancers. It combines cytoreductive surgery, which removes visible tumors, with heated chemotherapy circulated directly inside the abdominal cavity to destroy remaining microscopic cancer cells and reduce the risk of recurrence.

Unlike traditional chemotherapy delivered through the bloodstream, HIPEC delivers high-dose heated chemotherapy directly to the affected area, allowing better cancer targeting while reducing systemic side effects.

Why HIPEC Surgery is Used for Abdominal Cancers

HIPEC surgery is typically recommended when cancer spreads to the peritoneum, the thin lining that covers the abdominal organs.

Cancers commonly treated with HIPEC include:

• Colon cancer
• Ovarian cancer
• Stomach cancer
• Appendix cancer
• Peritoneal mesothelioma
• Peritoneal metastasis from other cancers

These cancers often spread within the abdominal cavity, where standard chemotherapy may not reach effectively. HIPEC allows doctors to deliver treatment directly to the affected area, improving the chances of controlling the disease.

HIPEC Surgery Procedure: Step-by-Step

HIPEC treatment is performed during the same operation as tumor removal.

• Cytoreductive Surgery
  Surgeons remove visible tumors from the abdominal cavity to reduce the overall tumor burden.
• Preparation for Chemotherapy
  After tumor removal, the abdominal cavity is prepared to circulate chemotherapy safely.
• Heated Chemotherapy Circulation
  A chemotherapy solution heated to approximately 41–43°C is circulated throughout the abdomen.
• Drug Absorption Phase
  The heated chemotherapy remains in the abdomen for 60–90 minutes to destroy microscopic cancer cells that cannot be seen during surgery.
• Completion of Surgery
  After the treatment cycle, the chemotherapy fluid is removed and the surgical incision is closed.

Benefits of HIPEC Surgery

HIPEC has emerged as an important treatment option for selected patients with abdominal cancers.

Key Advantages

• Targeted cancer treatment
  Chemotherapy is delivered directly to the tumor area.
• Higher drug concentration
  Doctors can safely use higher chemotherapy doses.
• Reduced systemic side effects
  Most of the chemotherapy remains inside the abdominal cavity.
• Improved survival outcomes
  Studies show improved survival in certain cancers treated with HIPEC.
• Single-session therapy
  Surgery and chemotherapy are performed in one procedure.

In selected cases, HIPEC may significantly improve survival compared to standard treatment approaches.

HIPEC Surgery Survival Rate

The survival rate after HIPEC surgery depends on several factors, including the type of cancer, the stage of disease, and how completely tumors are removed during surgery.

Studies suggest that selected patients undergoing cytoreductive surgery with HIPEC may experience median survival between 30 and 60 months, which can be better than standard chemotherapy alone for certain abdominal cancers.

Who is Eligible for HIPEC Surgery?

Not every patient with abdominal cancer is a candidate for HIPEC.

Doctors usually consider HIPEC when:

• Cancer is limited to the abdominal cavity
• Tumors can be surgically removed
• The patient is healthy enough for major surgery
• There is no widespread cancer outside the abdomen

A surgical oncologist evaluates each patient individually before recommending HIPEC treatment.

Important Facts About HIPEC Treatment

• HIPEC surgery combines tumor removal with heated chemotherapy.
• The treatment targets cancer cells inside the abdominal cavity.
• It is mainly used for cancers that spread to the peritoneum.
• HIPEC may improve survival in selected patients with abdominal cancers.
• The procedure should be performed in specialized cancer centers by experienced surgical oncologists.

Conclusion

HIPEC surgery is an advanced treatment that combines tumor removal with heated chemotherapy to target cancer cells inside the abdominal cavity. In selected patients with abdominal cancers, this approach may improve treatment outcomes and reduce recurrence. Consulting an experienced surgical oncologist can help determine whether HIPEC surgery is the right treatment option.
