A recently published study by Japanese researchers appears to show that a novel type of cancer immunotherapy helped shrink tumors in lab mice, which could bode as a promising treatment for mesothelioma cancer and other serious types of cancers. The study examined the use of near-infrared photoimmunotherapy, a type of technology that uses a chemical to make some cells more sensitive to light and then targets the cancer cells with focused light beams.
Through the course of their study, the Japanese team exploited certain proteins which mesothelioma tumors overexpress. By targeting these proteins with the photoimmunty treatments, researchers were able to shrink the size of the mesothelioma tumors in the mice studied. Furthermore, when the tumor cells exploded, the lab subject’s immune system was able to identify the remaining cancer cell tissues as foreign bodies and attack them in response to destroy the cancer.
Researchers believe that by using a combination of surgery to remove the tumor and photoimmunotherapy to destroy remaining tumor cells, doctors can make great strides in treating cancer. While surgery and chemotherapy have been the traditional methods used to treat mesothelioma, various types of immunotherapy have shown great promise to treat mesothelioma and other forms of aggressive cancers.
