To the Editor I read the article published by Wei et al1 investigating whether vein-first procedure or artery-first procedure would be better in terms of surgery of oncology. The authors demonstrated that artery-first procedure significantly increased circulating tumor cells and was significantly associated with worse survival outcomes. These results have a huge effect on surgery of lung cancer. I would like to add 1 point that should be discussed.
