Tretinoin is a derivative of vitamin A. It has the potential to enhance the effects of chemotherapy. Combining tretinoin with chemotherapy improved survival rates in mesothelioma in mice. Mesothelioma is a rare cancer that is hard to diagnose and treat. It develops on the thin layer of tissue that surrounds different internal organs and is a result of asbestos exposure. When treating mesothelioma, doctors will most of the time use more than one treatment to remove as many cancer cells as possible from a patient’s body. The standard therapies that are used include chemotherapy, radiation, and surgery.
When a patient gets chemotherapy treatment, he or she is given drugs that kill cells by damaging their DNA. Currently, the only FDA-Approved chemotherapy regimen for mesothelioma is a combination of pemetrexed and cisplatin. Cisplatin is a platinum-based drug. It works by damaging the DNA of dividing cells and slowing down the growth of cancer cells. Doctors have noticed that in some cases, cancer cells become resistant to cisplatin, making the treatment less effective.
Chemotherapy is commonly used to treat advanced cancers. It is not curative though and can have serious side effects. Immune checkpoint therapy boosts the body’s immune response against cancer. It has shown promise in improving outcomes. Not all patients respond to this treatment though and it can cause serious side effects. In a new study, researchers looked at drugs that could enhance the anti-cancer effects of chemotherapy. They found that tretinoin could improve the response to chemotherapy. It creates an environment within the tumor that is more sensitive to chemotherapy. It does this by increasing the presence of immune cells called CD8+ T cells in the tumor. These are known to be important for fighting cancer. The combination of tretinoin and chemotherapy was effective against mesothelioma. It did not show the same benefit in other types of cancer cells tested. Overall, tretinoin shows promise as a potential addition to chemotherapy in mesothelioma. More research is needed to understand the potential of this treatment in a clinical setting.
Clinical trials are a very important part of the cancer treatment process. Clinical trials allow for a safe way to test new treatments without putting patients in harm’s way. More research continues to be needed for the treatment of mesothelioma because there is currently no cure for the cancer. If more research is completed, maybe one day a cure for mesothelioma will be found and more people will live longer after a mesothelioma diagnosis.
