Medical inoperability is clearly defined, anatomical resectability is also pretty much clear (invasion of trachea/carina/esophagus, etc). But what about "oncological-meaningful" resectability? Bulky N2? Multi-Level N2? Many of these tumors are "technically" resectable, yet have a bad prognosis, so that we often opt for concurrent chemo-RT + durvalumab. Does a clearly defined list of such criteria exist?
