Outcome and prognostic factors were described. Methods: The MEDLINE database was searched using the PubMed engine to retrieve all relevant articles related to en bloc resection for pulmonary sulcus NSCLC invading the spine. All articles’ corresponding authors were contacted to share their most updated anonymized patient’s data. Data were pooled and analyzed, focusing on outcome and prognostic factors. Results: Search strategy yielded a total of 134 articles. Out of these, only 6 were relevant and non-duplicative. Four out of 6 authors were able to share updated data for a total of 135 patients.
