A new type of intraperitoneal chemotherapy wash called NIPEC improves survival rates of mesothelioma surgical candidates by over 30% when combined with the current standard of HIPEC. The therapy involves several cycles of room-temperature chemotherapy and is in the early stages of research.

Normothermic intraperitoneal chemotherapy, or NIPEC, is a room-temperature chemotherapy wash. Doctors administer it through an abdominal port. NIPEC, or NIPEC-LT, is a long-term treatment for malignant peritoneal mesothelioma patients.
It complements surgery by delivering consistent anti-cancer medication over multiple cycles. that complements surgery by delivering consistent anti-cancer medication over multiple cycles.
Delivering chemotherapy throughout the abdomen is called HIPEC: hyperthermic intraperitoneal chemotherapy. HIPEC chemotherapy is administered warm and only once, during cytoreductive surgery. NIPEC advances this method. It extends the anti-cancer effects of surgery and potentially improves disease-free survival.
For many years, chemotherapy has been systemic. It involves administering intravenous anti-cancer drugs through an IV line inserted in a vein or port. Systemic chemotherapy travels throughout your body in the bloodstream. It eventually reaches cancerous cells through small blood vessels.
NIPEC is an innovative type of chemotherapy wash applied directly to cancerous tissue within the abdomen. Called a “chemo bath,” the chemotherapy medication fills and circulates in the abdominal cavity. This kills cancer cells and reduces the chance of recurrence.
Evidence suggests NIPEC is most effective when combined with other forms of chemotherapy washes.
HIPEC, EPIC and NIPEC are the three primary types of chemotherapy washes used to treat peritoneal mesothelioma. They vary based on temperature and length of treatment.
Patients have longer survival times when undergoing surgery with HIPEC followed by EPIC and a series of NIPEC treatments. A 2022 study found that these interventions improved 5-year survival to about 80%.
The recommended administration of NIPEC is to give the first dose at four to six weeks postoperatively followed by five more cycles with three weeks between each treatment.
This new treatment may offer advantages over other chemotherapy washes alone because it is a long-term therapy that eradicates cancer cells long after surgery.
Doctors are still developing the best techniques for administering NIPEC. It has shown promising results in gastric cancer, ovarian cancer and peritoneal mesothelioma.
Ovarian cancer and peritoneal mesothelioma are two cancers caused by asbestos-contaminated talc.
Dr. Paul H. Sugarbaker is a pioneer in peritoneal therapy. He has worked on NIPEC as a new standard that improves patient survival over HIPEC mesothelioma treatment and other washes.
The NIPEC procedure can be either an inpatient or outpatient procedure. Doctors deliver it once patients have recovered from surgery.
NIPEC administration takes place over several steps. It involves multiple chemotherapy cycles. In most cases, surgeons will install the port during the initial surgery.
Doctors administer NIPEC after surgery as an adjuvant treatment in a multimodal plan. Multimodal treatment offers many anti-cancer therapy methods working together to eradicate tumors.
Combining treatment improves survival times and the prognosis for mesothelioma.
NIPEC is still in its early stages. It is most effective when combined with other chemotherapy washes such as HIPEC and EPIC after cytoreductive surgery.

We measure mesothelioma treatment success by the percentage of patients that live beyond five years. Doctors call it the five-year survival rate.
NIPEC can improve peritoneal mesothelioma patients’ five-year survival rate. It increases surgical effectiveness alongside other chemotherapy washes such as HIPEC.
NIPEC following HIPEC and post-surgical EPIC | 75% |
HIPEC followed by EPIC after surgery | 52% |
HIPEC alone administered during surgery | 44% |
Over 20 years ago, Sugarbaker helped create the current peritoneal mesothelioma treatment standard of HIPEC. Since then, he’s been able to identify the technique’s shortcomings and has developed NIPEC as the solution.
Surgeons first used NIPEC for ovarian cancer, but Sugarbaker explored its potential for peritoneal mesothelioma cancer in 2012.
Although the current results are impressive, Sugarbaker remains one of the few surgeons using it consistently today. He published a retrospective in 2020 of six malignant peritoneal mesothelioma patients treated with NIPEC. Four patients are free of disease after eight, 13, 18 and 19 years, and two patients died of illness 15 years after definitive treatment.
NIPEC is not available as a standard treatment at most mesothelioma treatment centers due to its limited development.
Sugarbaker currently serves as chief of the Peritoneal Surface Malignancy Program at the MedStar Washington Hospital Center in Washington, D.C., where patients may undergo NIPEC if they are eligible.
At MedStar Washington Hospital Center, Sugarbaker conducted his study on a group of six peritoneal mesothelioma patients who went on to live eight to 19 years after receiving NIPEC.
As development on NIPEC continues, treatment centers are expanding the availability of HIPEC and other intraperitoneal treatments. Patients should consult with their mesothelioma specialist about the possibility of a chemotherapy wash as part of their treatment plan.
NIPEC is a long-term chemotherapy regimen with potential side effects. Side effects of chemotherapy washes such as NIPEC and HIPEC are usually fewer or milder than with systemic chemotherapy.
As with any procedure, there are also possible complications with NIPEC. Complication risks will vary based on the patient’s overall health and stage of the disease.
While NIPEC offers many benefits to long-term survivability, there can be some disadvantages as well. Patients should discuss the pros and cons with their doctor, as other treatment options may better provide better benefits.
NIPEC is an exciting new treatment and may represent the future of peritoneal mesothelioma therapy. Combining long-term NIPEC with other chemotherapy washes has led to improved survival rates, but more research is still needed.
Researchers and specialists will continue to evaluate NIPEC for safety and effectiveness until the procedure becomes widely available.
