Dallas Cowboys owner Jerry Jones revealed he suffered from stage 4 melanoma for over a decade but survived, according to the Dallas Morning News.
Jones said his life was saved by an experimental drug treatment called PD-1 therapy, which, according to the American Cancer Society, keeps T cells from attacking normal cells.
“PD-1 is a checkpoint protein on immune cells called T cells. It acts as a ‘off switch’ to helps keep the T cells from attacking normal cells. PD-1 does this by attaching to PD-L1, a protein found on some normal and cancer cells. When PD-1 binds to PD-L1, it tells the T cell not to attack. Some cancer cells have large amounts of PD-L1, which helps them avoid being attacked by the immune system.”
Jones received treatment from the MD Anderson Cancer Center in Houston after being diagnosed in 2010 and went through four surgeries over the next decade, two on his lungs and two on his lymph nodes.
Jones said he is now tumor-free.
“I was saved by a fabulous treatment and great doctors and a real miracle [drug] called PD-1 [therapy],” Jones said. “I went into trials for that PD-1, and it has been one of the great medicines.”
Jones has been conducting interviews ahead of the release of the documentary “America’s Team: The Gambler and His Cowboys,” which debuts Tuesday on Netflix.
