HIPEC vs Traditional Surgery – Key Differences ExplainedA Complete Guide by Dr. Vimalathithan, Oncology Specialist – Chennai

Cancer treatment has evolved rapidly over the last decade. One of the most revolutionary advancements in abdominal cancer care is HIPEC — Hyperthermic Intraperitoneal Chemotherapy. For patients diagnosed with peritoneal cancers, HIPEC offers new hope, improved survival, and better long-term outcomes compared to conventional treatment methods.

As an Oncology Specialist in Chennai, Dr. Vimalathithan explains how HIPEC differs from traditional surgery and how to recognize which option is best for each patient.

📌 What Is Traditional Cancer Surgery?

Traditional cancer surgery focuses on:

• Removing the visible tumor

• Extracting affected tissues or organs

• Preventing the tumor from spreading further

• Supporting diagnosis through biopsy

This method is highly effective when:

• The tumor is localized

• Cancer has not spread to the abdominal cavity

• Early detection makes removal easier

However, traditional surgery cannot treat microscopic cancer cells that remain inside the abdominal lining, which may lead to recurrence.

📌 What Is HIPEC (Hyperthermic Intraperitoneal Chemotherapy)?

HIPEC is an advanced two-step cancer treatment involving:

1. Cytoreductive Surgery – Removal of visible tumors inside the abdomen

2. Heated Chemotherapy Wash – Circulating heated (41–43°C) chemotherapy inside the abdomen for 60–90 minutes

This method allows doctors to treat cancer locally, with minimal systemic toxicity.

HIPEC is highly effective for:

• Ovarian cancer with peritoneal spread

• Colorectal peritoneal metastasis

• Gastric cancer with abdominal spread

• Pseudomyxoma peritonei (PMP)

• Peritoneal mesothelioma

🔬 How HIPEC Works (Step-by-Step Explanation)

1️⃣ Removal of All Visible Tumor Deposits

The surgeon removes cancerous tissues from the abdomen — a process known as cytoreduction.

2️⃣ Direct Delivery of Heated Chemotherapy

A special HIPEC machine circulates heated chemotherapy fluid inside the abdominal cavity.

3️⃣ Heat Enhances Effectiveness

Heat improves drug absorption and kills cancer cells more effectively.

4️⃣ Targeted Treatment

Chemotherapy stays inside the abdomen, not throughout the entire body — greatly reducing side effects.

⭐ HIPEC vs Traditional Surgery — Key Differences

Feature	HIPEC	Traditional Surgery
Tumor Removal	Visible + microscopic cells	Only visible cancer
Chemotherapy	Heated chemo inside abdomen	IV chemotherapy (systemic)
Effectiveness	Higher for peritoneal cancers	Moderate
Recurrence Rate	Lower	Higher
Side Effects	Fewer due to localized chemo	More due to systemic exposure
Recovery	Longer initially, better long-term	Moderate
Best For	Advanced abdominal cancers	Localized tumors

⭐ Major Benefits of HIPEC

HIPEC offers several advantages that traditional surgery cannot:

1. Targets cancer cells that surgery alone cannot reach

Microscopic cancer cells floating in the abdomen are destroyed effectively.

2. Lower recurrence rate

Patients treated with HIPEC often experience significantly lower relapse.

3. Fewer side effects compared to regular chemotherapy

Because the drugs are not circulating through the whole body.

4. Heat itself kills cancer cells

Cancer cells cannot survive at the temperatures used in HIPEC.

5. Better long-term survival

Studies show improved survival for many abdominal cancers.

⭐ When Is HIPEC Recommended?

Dr. Vimalathithan may suggest HIPEC for patients diagnosed with:

• Ovarian cancer stage 3 or 4

• Colon cancer with peritoneal involvement

• Appendiceal cancer

• Pseudomyxoma peritonei

• Gastric cancer spread

• Peritoneal mesothelioma

HIPEC is not suitable for all patients — evaluation is required based on:

• Cancer stage

• Extent of abdominal involvement

• Overall health

• Prior treatments

⭐ Recovery After HIPEC vs Traditional Surgery

HIPEC Recovery

• Hospital stay: 7–10 days

• Initial fatigue and discomfort

• Gradual improvement over 3–6 weeks

• Long-term quality of life is significantly better

Traditional Surgery Recovery

• Hospital stay: 3–5 days

• Faster initial recovery

• May require additional cycles of IV chemotherapy

⭐ Which Treatment Is Better?

There is no “one-size-fits-all” answer.

However:

Traditional Surgery Is Better For:

• Early-stage cancers

• Localized tumors

• Patients who are not candidates for major cytoreductive surgery

HIPEC Is Better For:

• Cancers that have spread inside the abdomen

• Recurrent peritoneal cancers

• Cases where conventional therapy has limited success

Dr. Vimalathithan performs a detailed evaluation to choose the safest and most effective option.

⭐ Frequently Asked Questions (FAQs)

1. Is HIPEC safe?

Yes. HIPEC is performed by trained experts and offers excellent long-term benefits for patients with abdominal cancers.

2. Can HIPEC cure cancer?

While not a guarantee, HIPEC significantly improves survival and can eliminate cancer in many cases if done at the right time.

3. What cancers respond best to HIPEC?

Ovarian cancer, colorectal cancer, PMP, gastric cancer, and peritoneal mesothelioma.

4. Is HIPEC painful?

Patients are under general anesthesia. Post-operative pain is managed effectively.

5. How long does the HIPEC procedure take?

6–12 hours including surgery and heated chemotherapy.

6. What is the success rate of HIPEC?

Success varies by cancer type, but many patients see improved survival and quality of life.
