I’ve read that the peer-review process – where in a panel of independent experts within the field weigh in on the methods, results and so on – on such studies can take as long as the studies themselves.
So if the study phase takes six months, and the peer review takes six months, we’re probably looking at these PFS studies being published in the fall or winter of 2014.
But, again, I am just guessing here based on what I’ve read.
