According to a study, a new cancer vaccine is being reversed to the disease in nine patients. Researchers said that patients with fatal diseases along with cancer remained disease-free for at least three years after receiving doses.

Research, ending or metastized kidney cancer conducted by Yale University is testing individual remedies. For every person with the disease, the vaccine was unique to them, which was created by examining DNA and RNA in their tumors.

Scientists said that it helped identify personal mutations in each of their cancer which were not otherwise present in normal and healthy cells. Like all vaccines, individual cancer vaccines train to train the body’s immune system and destroy a danger.

How was the study done?

Researchers said that all nine participants had undergone surgery to treat phase three or four kidney cancer. After that, JAB promoted its immune system to search for any remaining cancer cells while avoiding healthy cells.

Currently approved immune treatments approved for kidney cancer are asked to “release brakes” on the immune system so that it allows to attack cancer cells, but they do not tell immune cells where to go. As a result, some patients do not get much benefit from treatment, while others may experience side effects from a highly active immune system.

The first writer and researcher of the study of Yale Cancer Center, Dr. “The idea behind this test was specifically to run the immune system that is unique to the tumor,” David Braun said. Sun. Kidney cancer is the 13th most common cancer worldwide, with 434,840 new cases diagnosed every year.

Dr. Braun stated that all the patients participating in the study were clarified the cell renel cell carcinoma, or CCRCC, and seven had stage three diseases. Two had stage four kidney cancer, and studies states that only 15 percent of patients with stage four live more than five years.

Kidney cell carcinoma is 80 percent of all types of kidney cancer. Standard treatment for patients with CCRCC is currently surgery to remove tumors, followed by immunotherapy with targeted therapy to explode the remaining cells. “For patients with high -risk CCRC, we want to improve post -surgery treatment options that reduce the risk of returning of cancer,” Dr. Braun said.

Nine patients received several doses of individual cancer vaccines. Four of them got only the vaccine, while the remaining five also had a small dose of immunotherapy drug iPilumumab. All nine patients had immune response to the vaccine within three weeks. Scientists said that in seven of the nine patients, T cells were able to identify the patient’s tumor. Cancer -fighting T cells remained elevated in the entire study and later, researchers saw.

“This strong and durable activation in T cells was encouraging and indicates that we are able to generate a long -lasting, anti -cancer immune response with vaccines,” Dr. Braun said.

Side effects of vaccine

Dr. According to Braun, patients experienced flu -like symptoms after one to two days after their vaccination, but no one reported any serious side effects. In addition, there was no major difference in the results between patients who received the JAB along with the IPILMUB and who received cancer vaccines.

Testing results, published in magazine Nature, It is said that it is promising. Researchers said that tests are required with more patients to confirm the effectiveness of the vaccine and detect its full potential.
