Anatomic resection, such as segmentectomy, provides more favourable outcomes than non-anatomic wedge resection in STAS-positive disease. Visceral pleural invasion is associated with an increased risk of distant metastasis, which may contribute to the comparable survival observed between segmentectomy and lobectomy in small VPI-positive tumours. The preoperative and intraoperative identification of both features remains limited due to the low sensitivity of frozen-section analysis for STAS and the modest accuracy of current radiologic predictors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>Tumour size alone is insufficient to guide surgical planning in early-stage NSCLC.
