In recent years, the treatment of cancer has continued to evolve, with scientists exploring innovative ways to tackle the disease. One of the most promising cancer treatments that have been gaining momentum is immunotherapy.
Immunotherapy involves using the body’s immune system to fight cancer by boosting its natural defenses or providing man-made immune system proteins to attack cancer cells. Since mesothelioma is a rare cancer that is notoriously difficult to treat, researchers have been exploring whether immunotherapy could be a viable treatment option for patients with mesothelioma.
If you or a loved one is suffering from mesothelioma, you’re probably wondering whether immunotherapy could be an effective treatment option for you. In this article, we’ll explore the latest advancements in mesothelioma and immunotherapy, including the benefits and limitations of this new treatment modality.
What is Mesothelioma?
Mesothelioma is a rare cancer that affects the thin layer of tissue that covers many of the internal organs (known as the mesothelium). It’s most commonly caused by exposure to asbestos, a mineral fiber that was extensively used in construction materials and other industrial products from the 1940s until the late 1970s.
Unfortunately, mesothelioma is often diagnosed at an advanced stage, and the prognosis is typically poor. According to the American Cancer Society, the five-year survival rate for mesothelioma is less than 10%.
What is Immunotherapy?
Immunotherapy is a type of cancer treatment that uses the body’s immune system to fight cancer. The immune system is the body’s natural defense mechanism against viruses, bacteria, and other harmful substances. It works by recognizing and attacking foreign invaders while leaving healthy cells alone.
Immunotherapy involves either boosting the immune system’s natural defenses or supplying it with man-made immune system proteins that can help fight cancer. These proteins can either stimulate the immune system to attack cancer cells or block signals that prevent the immune system from attacking.
What are the Latest Advancements in Mesothelioma and Immunotherapy?
Recently, there have been several breakthroughs in the use of immunotherapy to treat mesothelioma. Here are some of the latest advancements:
1. Pembrolizumab
Pembrolizumab is a type of immunotherapy that targets a protein called PD-1, which is found on the surface of T cells. By blocking PD-1, pembrolizumab can help activate the immune system to attack cancer cells.
A recent study showed that pembrolizumab can be effective in treating patients with mesothelioma. In the study, 25 patients with mesothelioma were treated with pembrolizumab. Of these patients, 4 had a partial response to the treatment, while 6 had stable disease. Although the study was small, it showed promising results and suggests that pembrolizumab could be a viable treatment option for some mesothelioma patients.
2. Nivolumab and Ipilimumab
Nivolumab and Ipilimumab are two types of immunotherapy that work by blocking proteins that prevent the immune system from attacking cancer cells. By blocking these proteins, nivolumab and ipilimumab can help activate the immune system to attack cancer cells.
A recent study showed that nivolumab and ipilimumab can be effective in treating mesothelioma. In the study, 125 patients with mesothelioma were treated with nivolumab and ipilimumab. Of these patients, 18 had a partial response to the treatment, while 67 had stable disease. Although the study was still ongoing, it showed promising results and suggests that nivolumab and ipilimumab could be a viable treatment option for some mesothelioma patients.
3. Tumor-Infiltrating Lymphocytes (TILs)
Tumor-infiltrating lymphocytes (TILs) are a type of immune cell that can be found in tumors. They are usually inactive or suppressed in tumors, but researchers have been exploring whether they can be activated and used to fight cancer.
A recent study showed that TILs can be effective in treating mesothelioma. In the study, 16 patients with mesothelioma were treated with TILs. Of these patients, 2 had a complete response to the treatment, while 8 had stable disease. Although the study was small, it showed promising results and suggests that TILs could be a viable treatment option for some mesothelioma patients.
Benefits of Mesothelioma and Immunotherapy
Mesothelioma and immunotherapy have several benefits, including:
1. Improved Survival Rates
Immunotherapy can help improve survival rates for patients with mesothelioma. Recent studies have shown that some patients with mesothelioma who received immunotherapy had improved survival rates compared to those who did not receive immunotherapy.
2. Fewer Side Effects
Immunotherapy typically has fewer side effects than traditional cancer treatments like chemotherapy and radiation therapy. This is because immunotherapy targets cancer cells specifically, while chemotherapy and radiation therapy can also damage healthy cells in the body.
3. More Effective Treatment Options
Immunotherapy can help provide more effective treatment options for patients with mesothelioma. This is particularly important since mesothelioma is notoriously difficult to treat and typically has a poor prognosis.
Limited Success of Mesothelioma and Immunotherapy
Despite the benefits of mesothelioma and immunotherapy, there are also some limitations to this treatment modality. Here are some of the limitations:
1. Not All Patients Respond to Immunotherapy
Unfortunately, not all patients with mesothelioma respond to immunotherapy. Although recent studies have shown promising results, some patients do not respond to the treatment, and there is still much research to be done to determine why this is the case and how to improve treatment outcomes.
2. Immunotherapy is Expensive
Immunotherapy can be expensive, and not all insurance plans cover the cost of treatment. This can make the treatment inaccessible to some patients who may benefit from it.
3. Immunotherapy Can Have Side Effects
Although immunotherapy typically has fewer side effects than traditional cancer treatments, it can still cause side effects. These side effects can include fatigue, fever, and muscle aches. In rare cases, immunotherapy can also cause more serious side effects like lung damage and organ failure.
