PIPAC Therapy: A Modern Treatment for Advanced Abdominal Cancer

PIPAC therapy (Pressurized Intraperitoneal Aerosol Chemotherapy) is an advanced, minimally invasive treatment used for cancers that spread within the abdominal cavity. It is especially helpful for patients who are not suitable for major surgery, offering better symptom control and improved quality of life.

What Is PIPAC Therapy?

PIPAC therapy is a technique where chemotherapy is delivered directly into the abdomen as a fine pressurized mist. Unlike traditional chemotherapy that travels through the bloodstream, this approach targets cancer cells locally.

The pressurized aerosol ensures even distribution of the drug across the abdominal lining and improves penetration into tumor tissues while reducing overall side effects.

Who Can Benefit from PIPAC Therapy?

PIPAC therapy is mainly recommended for patients with peritoneal carcinomatosis.

Suitable candidates include:

• Patients not eligible for CRS and HIPEC

• Cancer not responding to systemic chemotherapy

• Individuals with symptoms like ascites or abdominal pain

• Patients fit for minimally invasive procedures

Cancers Treated with PIPAC Therapy

PIPAC therapy is used in multiple abdominal cancers such as:

• Ovarian cancer

• Gastric cancer

• Colorectal cancer

• Appendix tumors

• Peritoneal mesothelioma

• Pancreatic cancers

Is PIPAC Therapy Curative?

PIPAC therapy is mainly a palliative treatment. Its goal is to slow disease progression and relieve symptoms.

In some cases, repeated sessions of PIPAC therapy may shrink tumors enough to allow further treatments like HIPEC, making it a bridging therapy.

How Is PIPAC Therapy Performed?

PIPAC therapy is done under general anesthesia using a laparoscopic approach.

Steps include:

1. Small incisions in the abdomen

2. Examination of the abdominal cavity

3. Removal of fluid and biopsy (if needed)

4. Delivery of aerosol chemotherapy under pressure

5. Safe removal of gas and closure

Duration and Recovery After PIPAC Therapy

• Procedure time: 90–120 minutes

• Hospital stay: Usually 1 day

• Recovery: Faster than open surgery

Follow-Up After PIPAC Therapy

After PIPAC therapy, patients may require:

• Regular doctor visits

• CT scans and blood tests

• Repeat sessions every few weeks

• Nutritional and supportive care

PIPAC Therapy vs HIPEC vs Chemotherapy

Benefits of PIPAC Therapy

• Minimally invasive

• Faster recovery

• Targeted drug delivery

• Fewer side effects

• Can be repeated

• Better symptom relief

When Is PIPAC Therapy Not Recommended?

Absolute conditions:

• Severe adhesions

• Active infection

• Bowel obstruction

• Serious heart/lung disease

Relative conditions:

• Malnutrition

• Prior extensive surgeries

• High tumor burden

Effectiveness of PIPAC Therapy

Studies show that PIPAC therapy can:

• Stabilize disease

• Reduce symptoms like pain and ascites

• Improve quality of life

Survival outcomes vary depending on patient condition and cancer type.

Side Effects of PIPAC Therapy

Common:

• Mild abdominal pain

• Nausea

• Fatigue

Rare:

• Infection

• Internal injury

• Bleeding

Overall, PIPAC therapy is better tolerated than traditional chemotherapy.

Conclusion

PIPAC therapy is an important advancement in treating advanced abdominal cancers. While it is not a cure, it provides effective symptom control and improves patient comfort. With ongoing research, its role in cancer treatment continues to expand.
