Title:A shift from distal to proximal neoplasia in the colon: a decade of polyps
and CRC in Italy.
Version: 1Date:24 November 2009
Reviewer: Yutaka Atomi
Reviewer's report:
This paper is not suitable for publication in our journal due to the following
reasons.
1) There are lots of misspelling and grammatical errors in this manuscript. The
authors should have asked native speakers to check their work before
submission.
2) Was there any necessity to show the annual data separately in Tables and
figures?
3) This was a single institutional study during a relatively short period of time. As
the authors commented in Discussion, this study contained lots of bias in its
design.
4) When an ordinary adenoma or an early cancer in the right colon and an
advanced adenoma or cancer in the left colon were located synchronously, the
former lesion was neglected and the latter lesion only was analyzed according to
the study protocol. This study design may obscure actual change of distribution
patterns, and may lead to wrong conclusions.
Level of interest: An article of limited interest
Quality of written English: Needs some language corrections before being
published
Statistical review: No, the manuscript does not need to be seen by a
statistician.
Declaration of competing interests:
