Important Facts About Mesothelioma Multimodal Therapy

  • Multimodal therapy applies different types of treatment to slow or stop the growth of cancer.
  • The purpose of multimodal therapy is to attack cancer tumors in various ways.
  • Mesothelioma multimodal therapy utilizes some combination of surgery, chemotherapy, radiation, immunotherapy and other novel options.
  • Two terms related to multimodal therapy are adjuvant and neoadjuvant therapy. Adjuvant therapy is treatment after surgery and neoadjuvant therapy is treatment before surgery.

How Mesothelioma Multimodal Therapy Works

Mesothelioma is stubborn and is resistant to most single therapies (called “monotherapy”). Tumors often continue growing and spreading despite initial effectiveness from chemotherapy drugs, immunotherapy drugs or radiation beams.

Multimodal therapy attacks mesothelioma tumors in multiple ways. This approach reduces the chances of tumors becoming resistant to a single therapy.

Two treatments working in tandem can make each individual therapy stronger. This is called a synergistic effect:

  • Immunotherapy makes the immune system a stronger ally for other therapies fighting mesothelioma
  • Chemotherapy weakens tumors, helping the immune system
  • Radiation breaks up the DNA of mesothelioma cells, which can inspire a response from the immune system

Components of Multimodal Therapy for Mesothelioma

Multimodal therapy for mesothelioma usually includes a combination of these five:










Tumor treating fields

Specific types of chemotherapy, immunotherapy and tumor treating fields are FDA-approved therapies for malignant pleural mesothelioma. Surgery and radiation are not FDA-approved and still considered experimental, although surgery provides the best survival rates for select patients.

Other multimodal therapy options are tested in clinical trials. They include:

Combining Mesothelioma Surgery With Other Treatments

Surgery is the first option considered for any mesothelioma case. While many patients have metastasis or are not healthy enough for surgery, this option is associated with the best survival times.

Cytoreduction with HIPEC is the best peritoneal mesothelioma surgery. The two surgeries for pleural mesothelioma are:

Doctors prefer to build multimodal treatment plans around mesothelioma surgery. The first multimodal therapy approach was combining surgery with chemotherapy and radiation.

Some clinical studies use immunotherapy before or after surgery. While immunotherapy drugs Opdivo and Yervoy are approved for malignant pleural mesothelioma, they’re only allowed for non-surgical cases. Their use as multimodal therapies with surgery is in the experimental phase.

Mesothelioma Neoadjuvant Treatment

Mesothelioma neoadjuvant treatment is therapy used before surgery. Patients can receive chemotherapy, radiation or immunotherapy (in clinical trials) before an aggressive mesothelioma surgery. The purpose is to shrink tumor volume and help surgeons remove the disease easier.

Mesothelioma Adjuvant Treatment

Mesothelioma adjuvant treatment is therapy used after surgery. Patients receive chemotherapy, radiation and immunotherapy (in clinical trials) after an aggressive surgery. The purpose is to treat any remaining tumors not taken out during the operation.

Multimodal Treatment With Mesothelioma Chemotherapy

Systemic chemotherapy works both before and after surgery, especially for pleural mesothelioma. Systemic chemotherapy is delivered intravenously into the bloodstream. The FDA approved intravenous cisplatin and pemetrexed for malignant pleural mesothelioma.

P/D survival can reach an average of 32 months when paired with chemotherapy. This length occurred from a study at Memorial Sloan Kettering Cancer Center.

Other studies led to median survival of:

  • 32 months for P/D with neoadjuvant and adjuvant chemotherapy
  • 32 months for P/D with adjuvant chemotherapy and radiation
  • 18 months for EPP with adjuvant chemotherapy and radiation


Multimodal Treatment With Mesothelioma Radiation

Doctors use radiation before or after pleural mesothelioma surgery:

  • Radiation is preferable after P/D.
  • Radiation is preferable before EPP.

SMART (surgery for mesothelioma after radiation therapy) led to a median survival of 24.4 months. The method started in Toronto, Canada, and is featured at multiple U.S. cancer centers. SMART usually relies on EPP as the surgery.

Two trials used P/D followed by radiation therapy:

  • Dr. Kenneth Rosenzweig, a mesothelioma specialist, reported in 2017 a median survival of 24 months.
  • Dr. Valerie Rusch, another specialist, reported in 2017 a median survival of 20 months.

Multimodal Treatment With Mesothelioma Intraoperative Therapies

The most well-known intraoperative therapy for mesothelioma is hyperthermic intraoperative chemotherapy (HIOC). There are two forms used for mesothelioma:

  • Hyperthermic intraperitoneal chemotherapy (HIPEC) for peritoneal mesothelioma
  • Hyperthermic intrathoracic chemotherapy (HITHOC) for pleural mesothelioma

HIOC sends hot liquid chemotherapy drugs into the abdomen or chest. Specialists deliver the drugs through ports or the surgical incision. This occurs the same day as surgery after the main resection is completed.

HIPEC is paired with cytoreduction for peritoneal mesothelioma. A study conducted at Wake Forest Baptist Cancer Center reported a median survival of 40 months and one-year survival rate of 77%. Another study surpassed a median survival of five years.

HITHOC with P/D or EPP was impressive in multiple studies:

  • 42 months median survival in 2019
  • 27 months median survival in 2020
  • 35.3 months median survival in 2013


Multimodal Treatment With Mesothelioma Immunotherapy

Mesothelioma immunotherapy helps the body fight cancer naturally. Some immunotherapy drugs are approved officially for malignant mesothelioma. Others are still in testing.

The FDA approved Opdivo and Yervoy for unresectable malignant pleural mesothelioma in October 2020. These two drugs are immune checkpoint inhibitors. They “take the breaks off” the immune system, as specialist Dr. Daniel Sterman explained, and help the body’s T-cells fight mesothelioma effectively.

The FDA’s approval was due to impressive results from a study:

  • Immunotherapy with chemotherapy led to median survival of 18 months.
  • This outperformed chemotherapy on its own.

Another study paired ramucirumab with chemotherapy. The median survival was 14 months, and more than half reached the one-year mark.

A study at Johns Hopkins Hospital in Baltimore, Maryland, gives patients Opdivo and Yervoy six weeks before surgery. This study is a groundbreaking example of pairing immunotherapy with aggressive pleural mesothelioma surgery.

Multimodal Treatment With Other Emerging Mesothelioma Therapies

Other mesothelioma therapies include:

  • Tumor treating fields
  • Gene therapy
  • Virotherapy
  • Photodynamic therapy

These therapies are often paired with some of the main options — surgery, chemotherapy, radiation or immunotherapy — in clinical studies. In some trials, these emerging options are paired together.

Multimodal Treatment With Mesothelioma Tumor Treating Fields

A tumor treating fields device is FDA-approved to treat malignant pleural mesothelioma. It’s approved for unresectable cases and must be used with chemotherapy. The device, Optune Lua, sends electric waves through the patient’s body.

Optune Lua has a median survival of 18.4 months, which outperforms chemotherapy alone.

Multimodal Treatment With Gene Therapy

Gene therapy is still in the infant stages of investigation for mesothelioma. The theory is to alter the genetics of cancerous cells, causing them to die, or repair the cells to health status.

Some trials use gene therapy with virotherapy or chemotherapy.

Multimodal Treatment With Mesothelioma Virotherapy

Virotherapy delivers a programmed virus to attack mesothelioma cells or induce an immune response — or both.

An example is ONCOS-102, a multimodal therapy despite being just one drug. It applies elements of virotherapy and immunotherapy. ONCOS-102 is an oncolytic adenovirus that breaks up mesothelioma cells and signals for the immune system’s help.

ONCOS-102 is close to FDA approval after median survival of 20-21 months. The manufacturer, Novocure, is planning a pairing of ONCOS-102 and immune checkpoint inhibitors, creating a new multimodal therapy approach.

Multimodal Treatment With Mesothelioma Photodynamic Therapy

Photodynamic therapy (PDT) sends a special drug, called a photosensitizer, into the patient. The drug attaches to mesothelioma cells.

These drugs are sensitive to light, and doctors aim a laser light at the location of the cancer. This causes the drug to react and kill the cancer cells.

Dr. Joseph Freidberg at the University of Maryland Medical Center paired PDT with P/D surgery. The median survival was 31.7 months.

PDT is still an experimental treatment. It can be used with surgery and chemotherapy.

How to Get Multimodal Treatment for Your Mesothelioma

The top Mesothelioma Centers of Excellence offer some form of multimodal treatment. Each cancer center may have a unique tweak to some of the combinations.

For instance, Michigan Medicine is the first U.S. cancer center to implement the SMART approach of radiotherapy before surgery. Wake Forest Baptist Cancer Center in North Carolina is one of the premier institutions for cytoreduction and HIPEC to treat peritoneal mesothelioma.

Other cancer centers offer clinical trials testing new multimodal approaches. A few other top mesothelioma hospitals are:

Many community hospitals don’t offer multimodal therapy for a rare cancer like mesothelioma. They’ll likely offer just one therapy, such as chemotherapy or radiation, but don’t have experienced surgeons for aggressive operations.
