Reviewer's report:
Thank you for an opportunity to review a case-report entitled "The Aggressive Surgical Treatment
and Outcome of a Colon Cancer Patient Infected with SARS-CoV-2 in Wuhan, China and OurExperience Sharing". I read the manuscript with great interest as COVID-19 pandemic surelyaffects the treatment of cancer patients - in this case a 69 y/o lady with ascending colon cancerwith incomplete colonic obstruction - complicated by severe novel coronavirus pneumonia.
Given the fact that there was no emergency condition requiring immediate surgical treatment and
antiviral drug was given for treating pneumonia, the patient eventually got well and underwent'scheduled' surgery at about 6 weeks after diagnosis of COVID-19 infection (with IgG +ve andRT-PCR -ve for the virus). It is well known that time from diagnosis to surgery mainly had noadverse effects on oncological outcomes in patients undergoing surgery for colon cancer providingthat it was not later than 8 weeks (Eur J Surg Oncol 2018;44:1479-1485). For these reasons, thismanuscript barely add new information to the published literature.
