Title: Epidemiology and prognostic analysis of patients with pancreatic  signet ring cell
carcinoma: a population-based study

Reviewer's report:
Dear Author,
I read with interest the manuscript you submitted to BMC Gastroenterology. As far as I can see,
you addressed all the comments provided by reviewers in the first place. I understand missing
data are unlikely to be fixed when retrospectively analyzing an administrative database as SEER.
However, this should be properly underlined in the manuscript, since it definitely constitutes
the major limitation of the study and prevents to draw absolute conclusions about the topics
under study.
Also, scientific English needs further improvement and proofreading before consideration for
publication in an international scientific journal.
