The short answer: HIPEC (heated chemotherapy washed through the belly during cancer surgery, often called garam chemo) is not experimental, but it is also not for everyone and not a guaranteed cure. It helps selected women, mainly with stage 3 ovarian cancer when all visible tumour can be removed and they are fit for a long operation, and the evidence is strongest when surgery comes after about three cycles of chemotherapy. Read about HIPEC eligibility and treatment to see who may be considered.
HIPEC (hyperthermic intraperitoneal chemotherapy) is one of the most misunderstood procedures in oncology. Below are 7 myths Dr. Nishtha hears repeatedly in consultations, and the evidence-based answers.

1. Myth: HIPEC is “experimental”
HIPEC has been performed worldwide for over 25 years, and international guidelines list it as an option that may be considered for selected women with stage 3 ovarian cancer at interval surgery (surgery after chemotherapy). The landmark 2018 New England Journal of Medicine trial by van Driel et al. (OVHIPEC-1) showed longer survival in that group. It is not experimental — but it is highly specialised, and a benefit at upfront (surgery-first) operations is not proven.
2. Myth: HIPEC is too painful to consider
HIPEC combined with cytoreductive surgery is a major procedure, but modern enhanced-recovery protocols mean most patients are mobilised within 24-48 hours. Pain is well-controlled with multimodal analgesia. Hospital stay is usually 10–14 days, including 3–5 days in intensive care.
3. Myth: HIPEC has a very low success rate
In carefully selected patients, HIPEC does help. In the main trial (OVHIPEC-1: women with stage 3 ovarian cancer having surgery after three cycles of chemotherapy), adding HIPEC delayed the cancer coming back by about 3.5 months (median 14.2 vs 10.7 months) and lengthened median overall survival by about 12 months (45.7 vs 33.9 months). That is a real benefit, but most women still needed further treatment later, so HIPEC is not a guaranteed cure. Results also depend on the team: centres that do this surgery regularly tend to have better outcomes.
4. Myth: HIPEC costs are out of reach
The total cost in Ahmedabad ranges Rs 5-12 lakh including the procedure, hospital stay, and standard pre-op work-up. Most cashless insurance policies cover HIPEC under cancer surgery benefits. PMJAY covers eligible families up to Rs 5 lakh per family per year.
5. Myth: HIPEC means no more chemotherapy needed
HIPEC is one component of treatment, not a substitute. Most patients still receive systemic chemotherapy before and/or after HIPEC. The HIPEC component specifically targets microscopic peritoneal disease that systemic chemotherapy alone cannot eradicate.
6. Myth: HIPEC works for any cancer that has spread in the belly
HIPEC is most established for advanced ovarian cancer, primary peritoneal cancer, pseudomyxoma peritonei, and selected colorectal cancers with peritoneal spread. It is NOT appropriate for every cancer, every stage or every patient: it is considered only when all visible tumour can be removed and the patient is fit for a long operation. Patient selection requires a specialist team.
7. Myth: Recovery from HIPEC takes a year
No. Most patients return to light activities within 4–6 weeks, and full recovery usually takes about 3–4 months. Energy can take longer to return fully, especially if chemotherapy follows. For a step-by-step guide, read about preparation and recovery around HIPEC.

HIPEC is only one part of ovarian cancer diagnosis and treatment; the team first decides the overall plan, including when surgery and chemotherapy should happen.

FAQs
Is HIPEC experimental?
No. It has been used for over 25 years and is a recognised option for selected women with stage 3 ovarian cancer at interval surgery (after chemotherapy). It is highly specialised and is not offered to everyone.
Is HIPEC surgery painful?
The operation is done under general anaesthesia. Afterwards, pain is controlled with several methods together (often an epidural), and most patients are helped to sit up and walk within 24–48 hours.
What is the success rate of HIPEC? Is it a cure?
It is not a guaranteed cure. In the main ovarian-cancer trial (OVHIPEC-1), median overall survival was about 12 months longer with HIPEC (45.7 vs 33.9 months) in women having surgery after chemotherapy. Benefit at upfront (surgery-first) operations is not proven.
How long is the hospital stay and recovery?
The operation often takes 8–14 hours. Most patients stay in hospital about 10–14 days, including 3–5 days in intensive care, and full recovery usually takes about 3–4 months.
Will I still need chemotherapy after HIPEC?
Usually yes. HIPEC is one component of treatment, not a substitute. Most patients also receive chemotherapy through a vein before and/or after the operation.
