Reviewer's report:  
 
It is a study that, although retrospective, analyzes in detail the problem of the treatment of GLM 
and adds considerable experience on the disease as well as a very valuable therapeutic advice.  
 
 
It should be taken into account:  
 
 
1.- Patients are analyzed fro m March 2008 to March 2014. Three years have passed since the 
reviewable data. Why so long?  
 
 
2.- The types of treatment as well as the duration vary a lot. Possibly depended on the 
invididualization of each case, however does not explain what reasons exist for one or another 
treatment. It would be interesting to explain.  
 
 
3.- I would like the authors to further specify the concept of recurrence. When they considered 
disease recurrence?
