Two series of consecutive TTNB with 18-gauge needles performed before and after the publication of the ATS/ERS/IASLC guidelines, were retrospectively compared regarding their adequacy for histological sub-typing and EGFR/KRAS mutations and ALK rearrangement testing.     ///    Adequacy of CT-guided biopsies with histomolecular subtyping of pulmonary adenocarcinomas: influence of ATS/ERS/IASLC guidelines..     ///    "With respect to ATS/ERS/IASLC guidelines, radiologists, biologists and pathologists have improved their practice. "    ///    " As metastatic pulmonary adenocarcinomas are routinely investigated for EGFR, KRAS, and ALK mutations/rearrangement, adequacy of CT-guided trans-thoracic needle biopsies (TTNB) needs to be evaluated in respect with the 2011 ATS/ERS/IASLC guidelines.
