American researchers test a hundred drugs in the laboratory on patients' tumor cells to identify the most accurate drugs against their cancer cells. The research, still in very early stages and with few patients, worked with Logan Jenner and the little boy, who is now eight years old, has now been cancer-free for two years.

According to the scientists, 21 patients underwent these drug tests and 20 of the participants also underwent genomic analysis. The researchers returned treatment recommendations for 19 and of them, 14 of them received therapeutic interventions. In eight cases, the oncologists were not guided by the indications reported by the project, but by the results of the project. The little boy had been battling aggressive myeloid leukemia since he was three years old. He was kept alive for 14 months, but kept coming back. The project kept him alive for three years, but he was kept back for six months. The results of this project are published this Thursday in Nature Medicine. The study was led by Diana Azzam, researcher in the Department of Environmental Health Sciences at the International University of Florida.
