Reviewer: Thomas Aparicio  
 
Reviewer's report:  
 
It is an interesting cases reports of 5 SBA occuring in coeliac disease.  
 
Despite the small number new findings are reported with these well describe cases  
 
Other comments  
 
Title: title is to emphatic. 5 cases could not resume research of millennium  
 
Abstract: conclusion should be nuanced as there is only 5 cases  
 
Discussion:  
 
1) It is very interesting that even poor prognostic patient (N2) according to the literature 
have a good prognosis in this study.  That should be pointed out  
 
 
2) The author recommand investigation for patient with CD to detect SBA. According to the 
low rate of SBA in CD (despite an elevated relative risk), the doubtfull about the 
adenoma to carcinoma sequence, the fact that in this st udy the majority of the cases had 
concomittent diagnosis of CD and SBA, and the lack of standardized repeated screening 
procedure it is difficult to made any recommandation about screening.  
 
 
3) SBA associate with Crohn disease are not located in duodenum (P alascak -Juif V, 
Inflamm Bowel Dis. 2005 ; Aparicio T, ESMO 2018, Ann Oncol (2018) 29 (suppl_8): 
viii150 -viii204)  
 
 
4) It is unclear that the new diagnostic tools allowed early diagnosis and better prognosis. A 
recent european study did not find a significant improvment of diagnosis and prognosis 
of SBA (Legue L, Acta Oncol 2016)  
 
 
5) Overall conclusion should be nuanced as it is difficult to draw robust findings from 5 
cases
