Does Preoperative Transbronchial Biopsy Worsen the Postsurgical Prognosis of Lung Cancer?

Conclusions: The postsurgical prognosis of the patients with NSCLC was significantly better if the preoperative TBLB was unsuccessful. This result suggested that advanced NSCLC had a tendency to be diagnosed with TBLB and, possibly, that the TBLB procedure might worsen the prognosis of patients with resectable NSCLC. We suggest that intraoperative diagnosis followed by the consecutive resection of NSCLC may be beneficial for improving the surgical outcomes of NSCLC patients.
