Purpose
CT-guided-lung biopsy (CTLB) is a relatively safe and widely accepted procedure for the diagnosis and characterization of several focal lung pathologies, including benign and malignant lesions.[1,8,9]
With advances in CT imaging and the growing interest of lung cancer screening, an increased incidence of small lung cancer, especially small adenocarcinoma, has been reported, and the management of lung nodules is becoming increasingly challenging.[2-5] Although observation strategy or direct surgical resection could be proposed if cancer probability is respectively low or high, many decision-making algorithms include a nodule-sampling step. [6,7] CTLB is considered as the standard technique, representing an essential step for diagnosis and treatment planning particularly for peripheral lung lesions and is capable of providing large samples allowing histological and biomolecular analysis. [10-13]
To our knowledge, no important studies have investigated CTLB performance according to nodule and patient characteristics, especially in those nodules showing poor evidence of glucose metabolism at 18-FDG PET examination. The aim of our study is to assess the possibility to select a subgroup of patients, with poor probability of biopsy technical success, who can benefit of different strategies.
