The combination of an experimental skin cancer vaccine, developed by Moderna Pharmaceuticals, with Merck’s Keytruda drug, was able to reduce the risk of death and recurrence of the disease in patients in a clinical study.
Preliminary results of the research were presented on Sunday at the meeting of the American Association for Cancer Research (AACR, its acronym in English), in Orlando, in the United States.
According to the researchers, the addition of the mRNA vaccine – the same technology used in Moderna’s vaccine against Covid-19 – to the Keytruda treatment, which accelerates the immune response, was 44% more effective than immunotherapy alone.
“From a general cancer therapeutic standpoint, this is a potential major breakthrough,” Ryan Sullivan, a melanoma specialist at Mass General Cancer, said in a statement.
The new data presented on Sunday adds details on partial results released by partner companies in December 2022.
The study included patients who were at high risk of melanoma recurrence. Among the 107 participants who received the experimental vaccine and Keytruda, 24 (22.4%) had their cancer return within two years of follow-up. Of the 50 treated with Keytruda alone, the cancer returned in 20 (40%).
Skin cancer is the most incident type of cancer in the country, according to the National Cancer Institute (Inca). The disease can appear anywhere on the body and, when identified early, has a good chance of being cured.Peter Dazeley/Getty Images

According to Inca, there are several types of the disease, which are generally classified as melanoma and non-melanoma Barcin/Getty Images

****Photo-doctor-investigating-paint-suspicion-2.jpgAccording to experts, it is important to investigate whenever a mole or mole has asymmetry, a rough or irregular edge, two or more colors, has a diameter greater than six millimeters, or changes in size over time. All of these signs can indicate the presence of a melanoma.kali9/Getty Images

It rarely spreads to other parts of the body, but if not identified in time, it can spread to deeper layers of the skin, making it difficult to treat.SCIENCE PHOTO LIBRARY/Getty Images
****Photo-skin-cancer-6.jpgThe diagnosis of skin cancer is made by the dermatologist through clinical examination. In certain situations, it may be necessary to carry out the exam known as “Dermoscopy”, which consists of using a device that allows you to visualize layers of the skin not seen with the naked eye. In more specific situations it is necessary to perform a biopsyNoctiluxx/Getty Images

****Picture-woman-putting-sunscreen-on-man.jpgAmong the recommendations for preventing skin cancer are: avoiding exposure to the sun, using sunglasses with UV protection, as well as umbrellas, umbrellas, wide-brimmed hats and clothes that protect the body. In addition, of course, to the daily use of sunscreen with a sun protection factor (SPF) of 15 or more.frankreporter/Getty Images

Immune system
Moderna’s vaccine is designed to train the immune system, it is made from the analysis of tumors taken from the patient. The vaccine teaches the body to recognize and attack specific cancer cell mutations.
Keytruda belongs to a class of immunotherapies known as checkpoint inhibitors designed to disable or kill the protein that helps cancer evade the immune system. (With information from Reuters agency)
