I have an opinion on this topic....several opinions actually! The paper is coming out soon. We included a tremendous amount of data. I hope you will read through it in your journal clubs. I agree with @Dr. First Last that the results of RTOG 0617 were a 'kick in the gut'. They were (and are) certain...

Re-reading the above commentary, I have updates to my prior comments. The manuscript on 'Experience matters...' has been published in preliminary form by the JNCI. It is worthy of thorough review and dialogue here. People may not like its message, but a 10% survival advantage is huge! It's a larger ...

This is either a difficult question, or very obvious (but with different conclusions) depending on who you ask. My medical oncologists are telling me that it's obvious that 60 Gy is the right dose given 0617, and no other dose is supportable at the moment. Some colleagues in Rad Onc say that it's ob...

The complexity of RTOG 0617 confounds the simple question of dose. A decade earlier, we attempted to mount a "Carolina Consortium" trial of high dose versus low dose and met with barriers: 60 or 63 Gy; 1.8 v 2.0 per fraction, elective nodal irradiation or not, but arguably the most contentious issue...

I am obliged to ask Jeff if one of the trendiest potential explanations for the 0617 results is being explored in a secondary analysis or at least contemplated, and that wo...

As the primary purpose of 0617 was to invetigate 74 Gy vs 60 Gy, and now the post hoc "secondary analyses" describe "a benefit" observed in reducing radiation pneumonitis from ~8% to ~ 4% when IMRT was used, is that observation for the entire study population? For those treated to 74 Gy? Is that mag...
