Not to sound rude, but you’re acting as if you’re the one who paved the way. In 2013, two genetic studies were already launched. --granted, one came from Brigham and Women’s, which has strangely started its own PFS-denial campaign. (that’s a whole other story)
Since genetic studies were already underway a decade ago, it’s hard to get excited about this, especially since you didn’t even mention them. It’s as if they never happened to begin with. You at least could’ve informed us if this study builds on that research, or if it has its own investigative framework.
