En Bloc Resection of a Primary Tumor and Lymph Nodes in Non-Small-Cell Lung Cancer.

ABSTRACT:

Purpose

We established a novel surgical procedure for resectable non-small-cell lung cancer (NSCLC), which involves resection of the affected lobe and regional lymph nodes without separation, namely en bloc surgery. We introduced the technical details and early and late outcomes by comparing them with those of conventional surgery.

Methods

We retrospectively analyzed patients who underwent lobectomy with hilar and mediastinal lymph node dissection for stages I-III NSCLC. A propensity score-matched analysis was performed based on demographic variables.

Results

Propensity score-matching yielded 317 pairs. En bloc surgery was not associated with a longer operation time, a higher amount of intraoperative bleeding, or a higher frequency of postoperative complications. The
