SRX OS vs PFS

While scrolling through the posts here and trying to understand the implications of the recent results, and what they may, or may not have, meant I ended up reading an article on another site which discussed SRX and OS vs PFS, which I found very helpful. There were a couple of links within that article, one to the FDA and the other to the Journal Of Clinical Oncology which were also very informative...  the link is **promotion blocked**/2015/05/15/sirflox-os-v-pfs/  for anyone interested.  I'm still very positive on SRX but it will be any sales increase/slowdown which will tell us how oncologists view the results.
