When cancer spreads within the abdominal cavity, treatment can become more complex. Depending on the type of cancer, its location, and how far it has spread, doctors may consider a specialized treatment called HIPEC surgery.
HIPEC stands for Hyperthermic Intraperitoneal Chemotherapy. It combines surgery to remove visible cancer with heated chemotherapy delivered directly into the abdominal cavity. It may be appropriate for carefully selected patients with certain cancers involving the lining of the abdomen.
Understanding how HIPEC works, who may benefit, and what the treatment involves can help patients and their families have more informed discussions with their cancer care team.
HIPEC is a specialized treatment generally performed after a procedure called cytoreductive surgery (CRS).
During cytoreductive surgery, the surgeon aims to remove as much visible cancer as possible from the abdominal cavity. Once this step is completed, a heated chemotherapy solution is circulated directly inside the abdomen to target microscopic cancer cells that may remain.
Unlike conventional intravenous chemotherapy, which travels through the bloodstream, HIPEC delivers chemotherapy directly to the abdominal cavity. The medicines, temperature, and duration of treatment are selected according to the patient's condition and the treatment protocol.
HIPEC is not suitable for every type of cancer or every patient. Its potential benefits depend on the specific diagnosis and clinical circumstances.
The procedure generally involves the following stages:
The cancer team reviews the patient's biopsy reports, imaging scans, medical history, general health, and extent of cancer spread. This helps determine whether cytoreductive surgery and HIPEC may be appropriate.
Under general anaesthesia, the surgeon removes visible cancer deposits from the abdominal cavity. Depending on the extent and location of the disease, this may involve removing affected tissues or parts of certain organs.
The goal is to achieve the greatest possible removal of visible disease while considering patient safety.
After the surgical removal of visible tumours, a specialized system circulates a heated chemotherapy solution through the abdominal cavity for a defined period. The heat and direct delivery of chemotherapy are intended to help destroy remaining microscopic cancer cells.
The chemotherapy solution is drained, and the surgical team completes the operation. The patient is then monitored closely during recovery.
The operation can be lengthy, particularly when extensive tumour removal is required. Hospital stay and recovery time vary according to the procedure, the patient's overall health, and any complications.
HIPEC may be considered for selected patients whose cancer involves the peritoneum, the membrane lining the abdominal cavity.
Depending on the diagnosis and clinical evidence, this may include:
The evidence supporting HIPEC differs across cancer types and clinical situations. The treatment is not routinely appropriate for every patient with these diagnoses.
A specialist team considers several factors before recommending this procedure.
Doctors assess where the cancer is located, how extensively it involves the peritoneum, and whether complete or near-complete removal of visible disease is feasible.
The original site of the cancer, its biological characteristics, and the available evidence for HIPEC in that particular diagnosis are important considerations.
HIPEC combined with cytoreductive surgery can be a major operation. Heart and lung function, kidney function, nutritional status, age-related considerations, and other medical conditions may influence eligibility.
Previous chemotherapy or other treatments, and how the cancer responded, may help the team determine the next appropriate step.
A team that may include surgical oncologists, medical oncologists, radiologists, pathologists, and other specialists can help assess the potential benefits and risks for an individual patient.
For appropriately selected patients, HIPEC may offer certain benefits when used alongside cytoreductive surgery.
However, the benefits are not identical for every cancer type. HIPEC does not guarantee a cure or prevent cancer from returning. Your oncologist can explain the evidence relevant to your diagnosis.
Because HIPEC is usually combined with extensive surgery, it carries risks that must be carefully discussed before treatment.
Possible complications include:
The specific risks depend on the chemotherapy medicines used, the extent of surgery, and the patient's health. Careful preparation and postoperative monitoring are important parts of treatment.
HIPEC and conventional systemic chemotherapy serve different purposes.
Conventional chemotherapy is generally delivered through a vein or by another systemic route, allowing medicines to circulate throughout the body. HIPEC delivers heated chemotherapy directly into the abdominal cavity during surgery, after the removal of visible cancer.
In some treatment plans, HIPEC is used alongside other cancer therapies rather than replacing them. Whether a patient needs chemotherapy before or after surgery depends on the cancer type, stage, treatment response, and specialist recommendation.
If HIPEC has been suggested as a possible treatment, consider asking:
These questions can help you understand the purpose of treatment and make decisions in collaboration with your care team.
HIPEC is a specialized treatment that may be beneficial for selected patients with certain cancers involving the abdominal cavity. However, deciding whether to proceed requires a detailed assessment of the cancer, the feasibility of surgery, the patient's overall health, and the evidence for HIPEC in that specific situation.
If you or a family member has been diagnosed with an abdominal or peritoneal cancer, consult a qualified surgical oncologist to discuss the diagnosis, available treatment options, and whether an individualized evaluation for HIPEC is appropriate.
