Immunotherapy Might Not Be a Good Option for Mesothelioma

Published: June 20, 2025

Mesothelioma is a rare and aggressive cancer mainly caused by asbestos exposure that creates challenges for patients and caregivers. Immune checkpoint inhibitors have brought hope to patients, but new data from Australia is raising questions about their safety and effectiveness. In order to make informed decisions, patients must understand all details about immunotherapy so they can know the effects it has on their bodies. A new article from the Journal of Thoracic Oncology shows the real-world results of immunotherapy for mesothelioma.

Mesothelioma treatment has changed with the approval of immune checkpoint inhibitors like ipilimumab and nivolumab. Clinical trials show promise but real-world evidence is more complex. Real-world evidence highlights high drug discontinuation rates, serious side effects, and the need for more treatments. This makes it crucial for the benefits and risks of immunotherapy to be carefully considered by each patient. The histological subtype of mesothelioma is crucial for immunotherapy responses. Some patients can benefit but others can face severe side effects without good responses. One example is that people with the epithelioid subtype often experience adverse events with no survival benefits. Non-epithelioid patients on the other hand may see some improvement. More research is needed to understand the differences and to identify the best candidates for immunotherapy.

Patients or their caregivers should speak to healthcare providers about the risks and benefits of immunotherapy. Not everyone is suited for immune checkpoint inhibitors as a treatment, despite their benefit for some patients. Factors like health, goals, and cancer type are crucial in the treatment decision process. New clinical trials now check for safety and effectiveness of immunotherapy in various patient groups. The goal of the clinical trials is to find out how to best use immunotherapy for mesothelioma. Mesothelioma treatment is very complex, especially when it is immunotherapy. It can be tough for patients and their caregivers. Staying informed, asking questions, and working closely with doctors can help people make the right decisions. These decisions should focus on the patient’s health.

Research is an important part of the cancer treatment process. Without research, we would not be where we are today in treating mesothelioma. Mesothelioma is a complex cancer that requires a multi-step approach for patients to see a benefit. Immunotherapy is just one part of multiple types of treatments that can help mesothelioma patients. With continuing research, mesothelioma treatments will help improve outcomes for mesothelioma patients globally.
