Reviewer's report:  
 
Dear Authors  
 
 
 
I read this paper with great interest. I think that this paper has clinical value and I hope your 
patient's good clinical course. I would like to ask several things to authors  
 
 
1. Authors described that there  is no recurrence of disease. I would like to ask whether 
complete remission was acquired or not? Did you check CT or Pet CT or EGD 
consecutively after RT?  
 
 
2. How did his symptom improve? No swallowing difficulty after RT?  
 
 
3. I would like to request authors to describe the outcome of head and neck BSCC more 
delicately.  
 
 
4. It is somewhat awkward to mention HPV suddenly. I think it is better to remove this 
information.  
 
 
 
 
Thank you.
