Round 1

Reviewer 1 Report

The paper is well written and the research topic is of great interest and modernity.

I have the following remarks.

1) The research was carried out in a well-defined geographical area with unique health assistance facilities that may or may not be replicated elsewhere. I think this limitation should be better emphasized in the title as well as in the discussion.

2) The authors assumed that the inferior survival in the pandemic cohort may be attributable to worse access to surgery, chemotherapy, and maybe to the hospital facility as a whole (people were told to stay at home in those days). Is it possible to evaluate which of these factors weighed more than the others?

3) The ultimate cause of death has not been elucidated. Is it possible that a certain amount of deaths of these pancreatic cancer patients might have been due to COVID itself? If this had been the case, then the entire scenario should be reinterpreted.
