  • Title: [Sublobar curative resection for non-small-cell lung cancer].
    Author: Bonnette P.
    Journal: Bull Cancer; 2012 Nov; 99(11):1069-75. PubMed ID: 23092959.
    Abstract:
    It has been proved that lobectomy for lung cancer of less than 3 cm is superior to sublobar resection (segmentectomy and wedge resection) in the Lung Cancer Study Group trial published in 1995. Lobectomy is therefore recommended, with lymph node resection. Nevertheless, some publications have shown identical or close results after segmentectomy for tumors of less than 2 cm, and after wedge resection for tumors of less than 1 cm. It is likely that local recurrences are avoided by respecting a macroscopic margin of more than 2 cm around the tumor. A new trial comparing lobectomy and sublobar resection has been ongoing since 2007 for tumors of less than 2 cm. Persistent ground glass opacities are now often discovered after screening, either pure or with a small solid component, and correspond to an in situ or a micro-invasive adenocarcinoma, that can be removed with sublobar resection without recurrence.
