The Power of Immunotherapy in Fighting Mesothelioma
Welcome to our article on the future of mesothelioma treatment through immunotherapy. As one of the most devastating types of cancer, mesothelioma requires a comprehensive approach to treatment that includes traditional methods like chemotherapy and radiation therapy. But in recent years, medical professionals have turned their attention to a promising new approach: immunotherapy.
Immunotherapy is a type of cancer treatment that harnesses the body’s natural immune system to fight cancerous cells. Unlike chemotherapy, which can have a range of difficult side effects, immunotherapy is designed to target only cancerous cells while leaving healthy cells intact. This makes it an appealing option for patients and doctors alike.
In this article, we will explore the potential of immunotherapy in treating mesothelioma. We’ll examine how it works, what types are available, and what it could mean for the future of cancer treatment. Let’s dive in!
What is Mesothelioma?
Mesothelioma is a rare and aggressive form of cancer that affects the thin layer of tissue that lines the lungs, chest cavity, and abdomen. It is caused by exposure to asbestos, a mineral once widely used in construction, shipbuilding, and other industries.
Despite being relatively rare, mesothelioma has a high mortality rate, with most patients only living a few months after diagnosis. This is due, in part, to the fact that mesothelioma is often not diagnosed until it has progressed to a later stage.
How Does Immunotherapy Work?
Immunotherapy works by harnessing the power of the immune system to identify and attack cancerous cells. Normally, the immune system is able to identify and destroy abnormal cells that could potentially become cancerous. However, cancerous cells are able to evade this process by using certain proteins that trick the immune system into thinking they are normal cells.
Immunotherapy aims to overcome this by targeting these proteins, known as immune checkpoints, and allowing the immune system to recognize and attack cancerous cells. There are a variety of different types of immunotherapy, but most fall into one of two categories: checkpoint inhibitors and CAR T-cell therapy.
Checkpoint Inhibitors
Checkpoint inhibitors are drugs that block the proteins that cancer cells use to evade detection by the immune system. By blocking these proteins, the immune system is able to recognize and attack the cancerous cells.
One of the most promising checkpoint inhibitors for mesothelioma is pembrolizumab, which has shown significant promise in early clinical trials. Another checkpoint inhibitor, nivolumab, has also shown some success in treating mesothelioma.
How Does Pembrolizumab Work?
Pembrolizumab is a monoclonal antibody that targets a protein called PD-1, which is often overexpressed in cancer cells. By blocking PD-1, pembrolizumab allows the immune system to recognize and attack cancerous cells more effectively.
CAR T-Cell Therapy
CAR T-cell therapy is a type of immunotherapy that involves modifying a patient’s own immune cells to better target and attack cancerous cells. The process involves harvesting the patient’s T-cells, a type of white blood cell that plays a key role in the immune system, and modifying them in a lab to better target cancer cells. The modified cells are then reintroduced into the patient’s body, where they continue to multiply and attack cancerous cells.
CAR T-cell therapy is still in its early stages, but early clinical trials have shown promise for treating mesothelioma. One study found that patients who received CAR T-cell therapy had a median overall survival of 10 months, compared to just six months for patients who received chemotherapy.
What are the Benefits of Immunotherapy for Mesothelioma?
Immunotherapy offers several potential benefits for mesothelioma patients:
👉 Targeted treatment: Immunotherapy targets only cancerous cells, leaving healthy cells unharmed.
👉 Fewer side effects: Unlike chemotherapy, which can have a range of difficult side effects, immunotherapy is generally well-tolerated by patients.
👉 Potential for long-term remission: Immunotherapy has been shown to be effective in some patients with advanced mesothelioma, potentially leading to long-term remission.
What are the Challenges of Immunotherapy?
While immunotherapy is a promising new approach to mesothelioma treatment, there are still several challenges that need to be overcome:
👉 Limited options: While there are a few checkpoint inhibitors and CAR T-cell therapies that have shown promise in treating mesothelioma, the field is still relatively new and there are limited options available.
👉 Patient selection: Not all patients with mesothelioma will be eligible for immunotherapy, as it requires a certain level of overall health and immune function to be effective.
👉 Cost: Immunotherapy can be expensive, and it may not be covered by all insurance providers.
The Future of Immunotherapy for Mesothelioma
Despite the challenges, the future looks bright for immunotherapy in treating mesothelioma. Researchers are continuing to explore new approaches and refine existing treatments, with the aim of improving outcomes for patients.
As of now, checkpoint inhibitors like pembrolizumab are the most promising approach for mesothelioma treatment, but there is still much to learn about how best to use these drugs and which patients will benefit most. CAR T-cell therapy is also showing promise, but it is still in the early stages and requires further testing.
We can expect to see continued research and development in this field, with the ultimate goal of improving outcomes and extending the lives of mesothelioma patients.

Frequently Asked Questions
What is the success rate of immunotherapy for mesothelioma?
Immunotherapy is still a new approach to mesothelioma treatment, and success rates vary depending on the specific treatment used and the patient’s overall health. However, clinical trials have shown promising results, with some patients experiencing long-term remission.
Is immunotherapy covered by insurance?
It depends on the individual insurance provider. Immunotherapy can be expensive, and some insurance providers may not cover it.
Can all patients with mesothelioma receive immunotherapy?
No. Immunotherapy is not suitable for all patients with mesothelioma, and eligibility depends on factors like overall health and immune function.
What are the side effects of immunotherapy?
While immunotherapy is generally well-tolerated by patients, it can cause side effects like fatigue, fever, and nausea. More serious side effects are rare but can occur.
How long does immunotherapy take to work?
It varies depending on the specific treatment used and the patient’s overall health. Some patients may start to see results within a few weeks, while others may take several months to respond.
Is immunotherapy painful?
No. Unlike some types of cancer treatment, immunotherapy is generally not painful.
What is CAR T-cell therapy?
CAR T-cell therapy is a type of immunotherapy that involves modifying a patient’s own immune cells to better target and attack cancerous cells.
What is pembrolizumab?

What are immune checkpoints?
Immune checkpoints are proteins that cancer cells use to evade detection by the immune system.
