It’s actually jarring me quite a bit that it’s taken 8 years (6 if we take into consideration the fact that the study was only filled in 2015) for the Baylor paper on epigenetic changes to be compiled, and we’re still waiting.
Surely, there are some means of attaining epigenetic testing in the meanwhile (if this study ever comes out) in order to prove/ disprove the epigenetics hypothesis of PFS.
