Role of surgery for stage IIIA-N2 non-small cell lung cancer

Perhaps no topic other than stage IIIA-N2 non-small-cell lung cancer management is as controversial among surgeons, radiologists and medical oncologists. Much of the debate relates to the choice between surgical resection and radiation as the local controlmodality. Although limited, available evidence from randomized controlled trails raised concerns about the role of surgical resection. However, there is no perfect study, and the results should not be over-interpreted. This mini review will scrutinize these trials, focusing on the study design, results and, most importantly, limitations, and will explore the possible role of surgery for stage IIIA-N2 non-small-cell lung cancer.
