A multidisciplinary team of specialists, including medical oncologists, surgeons, radiation oncologists, and pulmonologists, is essential for creating a comprehensive treatment plan.

This article aims to provide an up-to-date overview of mesothelioma treatment options available in 2025, focusing on both established methods and cutting-edge research. We will discuss the benefits and limitations of each approach, explore ongoing clinical trials, and offer insights into the evolving landscape of mesothelioma care. Our goal is to empower patients and their families with the knowledge they need to make informed decisions and navigate the complexities of this challenging disease.

Current Standard of Care for Mesothelioma

The current standard of care for mesothelioma typically involves a multimodal approach, combining surgery, chemotherapy, and radiation therapy. The specific combination and sequence of these treatments are tailored to the individual patient’s characteristics and the stage of their disease.

Surgery

Surgical options for mesothelioma depend on the location and extent of the tumor. Two primary surgical procedures are commonly used for pleural mesothelioma (affecting the lining of the lungs):

• Extrapleural Pneumonectomy (EPP): This is a radical surgery involving the removal of the affected lung, the pleura (lining of the lung), part of the diaphragm, and the pericardium (sac around the heart). EPP is a highly invasive procedure and is typically reserved for patients with early-stage disease and good overall health.
• Pleurectomy/Decortication (P/D): This surgery involves removing the pleura and any visible tumor tissue. P/D is a less invasive option than EPP and may be suitable for patients who are not candidates for more aggressive surgery. It aims to relieve symptoms and improve quality of life.

For peritoneal mesothelioma (affecting the lining of the abdomen), cytoreductive surgery (CRS) is often performed. CRS involves removing as much visible tumor tissue as possible, followed by hyperthermic intraperitoneal chemotherapy (HIPEC).

Chemotherapy

Chemotherapy remains a cornerstone of mesothelioma treatment. The standard chemotherapy regimen for pleural mesothelioma typically involves a combination of pemetrexed (Alimta) and cisplatin. Other chemotherapy drugs, such as carboplatin, gemcitabine, and vinorelbine, may be used in certain situations or if the patient cannot tolerate the standard regimen. For peritoneal mesothelioma, chemotherapy is often administered systemically or as part of HIPEC.

Radiation Therapy

Radiation therapy uses high-energy rays to kill cancer cells. It may be used as a primary treatment for mesothelioma or as an adjuvant therapy after surgery to kill any remaining cancer cells. Radiation therapy can also be used to relieve symptoms, such as pain or shortness of breath. Techniques like intensity-modulated radiation therapy (IMRT) are used to precisely target the tumor while minimizing damage to surrounding healthy tissues.

Emerging Treatment Options and Advances in 2025

Significant research efforts are focused on developing novel therapies for mesothelioma. Several promising approaches are showing potential for improving patient outcomes.

Immunotherapy

Immunotherapy harnesses the power of the body’s own immune system to fight cancer. Immune checkpoint inhibitors, such as pembrolizumab (Keytruda) and nivolumab (Opdivo), have shown promising results in treating mesothelioma. These drugs work by blocking proteins that prevent the immune system from attacking cancer cells. The combination of nivolumab and ipilimumab is approved for the treatment of unresectable pleural mesothelioma.

Ongoing research is exploring new immunotherapy strategies, including:

• Adoptive Cell Therapy (ACT): This involves collecting immune cells from the patient, modifying them in the laboratory to enhance their ability to fight cancer, and then infusing them back into the patient.
• Cancer Vaccines: These vaccines are designed to stimulate the immune system to recognize and attack cancer cells.
• Oncolytic Viruses: These are genetically engineered viruses that selectively infect and kill cancer cells.

Targeted Therapy

Targeted therapies are drugs that target specific molecules or pathways involved in cancer cell growth and survival. While targeted therapies have not been as successful in mesothelioma as in some other cancers, research is ongoing to identify potential targets and develop effective drugs. Some promising targets include:

• VEGF (Vascular Endothelial Growth Factor): This protein promotes the growth of new blood vessels, which are essential for tumor growth. Drugs that block VEGF, such as bevacizumab, may be used in combination with chemotherapy.
• MET (Mesenchymal-Epithelial Transition Factor): This receptor tyrosine kinase is involved in cell growth and survival. MET inhibitors are being investigated in clinical trials for mesothelioma.

Gene Therapy

Gene therapy involves introducing genetic material into cells to treat disease. In mesothelioma, gene therapy is being explored as a way to deliver cancer-killing genes directly to tumor cells or to enhance the immune response against the tumor. Clinical trials are investigating the use of gene therapy in combination with other treatments, such as chemotherapy and radiation therapy.

Hyperthermic Intraperitoneal Chemotherapy (HIPEC) Advances

For peritoneal mesothelioma, advancements in HIPEC techniques are improving outcomes. Refinements in the chemotherapy drugs used, the duration of treatment, and the temperature of the perfusate are all being studied. Additionally, researchers are exploring the use of novel drug delivery systems to enhance the effectiveness of HIPEC.

Clinical Trials: A Gateway to New Treatments

Clinical trials are research studies that evaluate the safety and effectiveness of new treatments. Participating in a clinical trial can provide access to cutting-edge therapies that are not yet widely available. Patients with mesothelioma should consider participating in a clinical trial, as it may offer the best chance for improved outcomes. Resources such as the National Cancer Institute (NCI) and the Mesothelioma Applied Research Foundation (MARF) provide information about ongoing clinical trials.

Finding Relevant Clinical Trials

Identifying relevant clinical trials can be a complex process. It’s important to discuss potential clinical trial options with your oncologist. Online resources and patient advocacy groups can also help you find trials that are appropriate for your specific situation. Factors to consider when evaluating a clinical trial include:

• Eligibility Criteria: Each clinical trial has specific eligibility criteria that patients must meet in order to participate.
• Treatment Protocol: Understand the treatment protocol and potential risks and benefits.
• Trial Phase: Clinical trials are conducted in phases, with each phase designed to answer different questions about the treatment.
• Location: Consider the location of the trial and whether you are able to travel to the treatment center.

Palliative Care and Supportive Therapies

Palliative care focuses on relieving symptoms and improving quality of life for patients with serious illnesses, such as mesothelioma. It can be provided at any stage of the disease and is often integrated with other treatments. Supportive therapies can help manage side effects of treatment and improve overall well-being.

Managing Symptoms

Mesothelioma can cause a variety of symptoms, including pain, shortness of breath, fatigue, and nausea. Palliative care can help manage these symptoms through:

• Pain Management: Medications, nerve blocks, and other techniques can be used to relieve pain.
• Respiratory Support: Oxygen therapy, thoracentesis (removing fluid from the chest cavity), and pleurodesis (sealing the space between the lung and chest wall) can help improve breathing.
• Nutritional Support: Dietitians can provide guidance on maintaining adequate nutrition and managing side effects that affect appetite.
• Emotional Support: Counselors and support groups can provide emotional support and help patients cope with the challenges of mesothelioma.

Improving Quality of Life

Palliative care aims to improve the overall quality of life for patients with mesothelioma by addressing their physical, emotional, and spiritual needs. This can involve:

• Physical Therapy: Physical therapy can help maintain strength and mobility.
• Occupational Therapy: Occupational therapy can help patients adapt to changes in their ability to perform daily activities.
• Spiritual Care: Chaplains and other spiritual advisors can provide spiritual support and guidance.
