Hopefully Tony will give you a short summary of some of his research, experiences, and very thoughtful decision-tree work on HT treatments. (Look for his Journey under TC-Las Vegas.)
At my pre-surgery 2nd opinion consultations at M.D. Anderson, Dr. Maten indicated that he recommends considering the HT approach first
for most capsular penetration.
I'm sure the decisions are more complex and individualized than this generalized comment.
While I don't look to be a candidate for HT Therapy (See updated signature below!), I really do appreciate the question and Susan's information.
