My RO told me that had he known that my SCC was 
HPV+ he MAY HAVE treated me less aggressively. Remember I "only had" the rad and chemo so I still don't know what he would have cut back on and knowing what I know now and knowing how I turned out, I'm not sure that I would have wanted to be some test patient but hopefully 
HPV research and testing will continue and these and plenty more questions will be resolved. Hopefully one day Gardasil and other vaccines will eliminate 
HPV caners all together. I still advocate getting tested for 
HPV, especially if one fits the current profile. I don't see any harm in the treating facility having that knowledge.
