Debulking surgery, sometimes referred to as cytoreduction or tumor debulking, is a surgical procedure that is used to treat some types of cancers.

What Is Debulking Surgery?

Doctors may recommend debulking surgery for a wide range of cancer types. However, it is most frequently used to treat ovarian cancer or endometrial (uterine) cancer, as well as cancers that have spread from another location to the lining of the abdomen (peritoneum). Its goal is to remove as much cancer as possible from someone’s body. Debulking surgery is often combined with other treatments as part of a comprehensive cancer care plan.

Tumor Debulking Procedure

Debulking surgery is performed by expert surgeons under general anesthesia. The goal is to surgically remove tumors from the body, and leave behind no remaining disease. The procedure may be performed using a traditional incision in the abdomen or using more minimally invasive techniques that require smaller incisions.

For people with ovarian cancer, debulking surgery usually involves removing the ovaries and fallopian tubes and, in some cases, the uterus or cervix. Surgeons may also need to remove a small piece of the colon, small intestine, bladder or other organs in order to fully remove cancer from the body.

How Long Does It Take?

Most debulking surgeries take between 4 and 9 hours, depending on a variety of factors including the extent of the cancer, its location and a patient’s overall health. Sometimes, a debulking surgery is combined with hyperthermic intraperitoneal chemotherapy (HIPEC).

Recovery

Patients may stay in the hospital for up to 7 days after debulking surgery. During this time, they are monitored closely by nurses and doctors. Immediately after surgery, patients often need intravenous medicines and fluids and they may also have tubes inserted into the abdomen to help drain blood, fluid and urine.

For at least the first 6 weeks after returning home, patients should:

• Slowly build up their activity levels over time
• Avoid heavy lifting or housework
• Avoid driving
• Gradually return to a normal diet

If debulking surgery also included removal of part of the bowel, it may take longer for bowel movements to return to normal. Patients should talk to their doctor or nursing team about how to manage a return to normal bowel function.

Debulking Surgery Side Effects

As with any type of surgical procedure, debulking surgery may cause some side effects. Patients should contact their care time if they experience any of the following signs of possible complications or side effects.

Infection: Signs of an infection may be swelling or soreness at the site of an incision, a fever or chills, or — in the case of a chest infection — a cough or a feeling of being generally unwell.

Blood clots: Caused by blood not moving around the body as normal, blood clots may cause sore, swollen or red spots, often on the legs.

Internal bleeding: Although rare, some patients may experience internal bleeding during or immediately after surgery, requiring a blood transfusion.

Vaginal bleeding: Light spotting or bleeding from the vagina is normal immediately after surgery. If it continues, becomes heavier or is accompanied by green or yellow discharge, patients should contact a doctor immediately.

Lymphedema: If any lymph nodes are removed during surgery, this may lead to lymphedema, a build-up of lymph fluid, most often in the legs.

Issues with urinating or bowel movements: If surgery involves removing part of the bladder or bowels, this may cause changes to urination or bowel movements. In most cases, these issues are fixed during debulking surgery or in a follow-up procedure.

How Successful Is Debulking Surgery?

Studies have shown that debulking surgery may be a highly successful treatment option for patients with advanced ovarian cancer, significantly improving the chances that their cancer may be treated effectively or cured. Debulking surgery is most effective when it achieves what is known as “optimal debulking,” meaning that surgeons are able to remove all visible tumors.
