The Society of Thoracic Surgeons (STS) Clinical Practice Guideline on Surgical Management of Oligometastatic Non-small Cell Lung Cancer.

Background: The use of local consolidative therapy (LCT) in patients with oligometastatic non-small cell lung cancer (NSCLC) is rapidly evolving, with a preponderance of data supporting the benefits of such therapeutic approaches incorporating pulmonary resection for appropriately selected candidates. However, practices vary widely institutionally and regionally, and evidence-based guidelines are lacking.

Methods: The Society of Thoracic Surgeons assembled a panel of thoracic surgical oncologists to evaluate and synthesize the available evidence regarding the role of pulmonary resection as LCT. Clinical and research questions of interest were identified, and a complete literature review was conducted. Best practice guidelines were developed accordingly.

Results: The panel identified 7 areas of controversy, and data were assimilated to support the best recommended practices related to these clinical issues. Ultimately, a number of issues in this realm were found to have a high level of evidence to support the role for surgical therapy in patients with stage IV lung cancer. However, the nuances of how these operations are conducted remain in equipoise, without ample evidence to support the extent of resection or nodal dissection.

Conclusions: Clear data exist to support the use of surgical resection of the primary lung tumor as LCT in stage IV lung cancer. Evidence-based recommendations have been provided to guide multidisciplinary teams on the implementation of treatment plans as well as to guide researchers on areas of ongoing need for further investigation.
