of ICPN whose natural history was closely followed by ultrasound.
Version: 
0 
Date: 
18 Apr 2022
Reviewer's report:
1. ICPN - better term would be intracholecystic papillary neoplasm. Using
intracystic papillary neoplasm is vague as these are also seen in other organs.
2. Molecular alterations and prognosis of ICPN when compared to other gall
bladder cancers needs to be discussed.
3.. Further elaboration on what type of gastric ICPN would be great 
4. The ICPN has better prognosis when compared to other types of gall bladder
cancers. 
5. Grammar and English need improvement.
