I have absolutely no idea what the current frontline treatment drugs are for literally any form of cancer, and would bet the same is true for almost everyone else here. Most of the exceptions are people who know the frontline treatment drugs for one or two forms of cancer that impacted them personally. "And then you never hear about it again" is subtly implying that the drugs behind headlines never proceed beyond that point, but I didn't hear about it when the current frontline became the frontline treatment for any form of cancer. Most people just aren't in the loop about the evolution of the field of oncology, beyond pop-sci headlines.

And yes, most headlines like this don't result in changes to the care provided to anybody outside of clinical trials, but some do, and you and I probably won't hear about those either.
