The following published paper gives the detail and summary of every trial conducted on localized treatments. It's 187 pages long and also gives states on side affects of each treatment option.
Basically the summary says there is no evidence to confirm that one option is better than another, although some options do have less side affects. It's interesting reading if you have nothing else to do.
