Comparison of Brock University, Mayo Clinic and Herder models for pretest probability of cancer in solid pulmonary nodules.

Objective: Risk analysis models, which are used in the diagnostic algorithm of incidental pulmonary nodules, are based on patient data from developed countries. Mayo Clinic, Brock University and Herder are among the most known models. We aim to compare the reliability of these models in patients with indeterminate solid nodules and to investigate the contribution of the predictors used to the model.

Comparison of typical and atypical computed tomography patterns regarding reversibility and fibrosis in pulmonary sarcoidosis.

Purpose: This study aims to investigate whether there is a significant difference between typical and atypical parenchymal patterns in the development of fibrosis, which is the most crucial factor affecting morbidity in pulmonary sarcoidosis.

Methods: In our hospital, 145 cases with Siltzbach Types 2 and 3 sarcoidoses diagnosed by clinical, radiological, and histopathologic were retrospectively investigated. Perilymphatic nodules, accompanying mosaic attenuation, and interlobular septal thickening and central peribronchovascular bunch-like thickening on high-resolution computed tomography were assessed as typical.

Effect of Asbestos Exposure on the Frequency of EGFR Mutations and ALK/ROS1 Rearrangements in Patients With Lung Adenocarcinoma: A Multicentric Study.

Objective: The aim of this study is to investigate the effect of asbestos exposure on cancer-driver mutations.

Methods: Between January 2014 and September 2018, epidermal growth factor receptor (EGFR), anaplastic lymphoma receptor tyrosine kinase (ALK), and c-ros oncogene 1 receptor tyrosine kinase gene (ROS1) alterations, demographic characteristics, asbestos exposure, and asbestos-related radiological findings of 1904 patients with lung adenocarcinoma were recorded.

Results: The frequencies of EGFR mutations, ALK, and ROS1 rearrangements were 14.

Diagnostic success of transthoracic needle biopsy and PET-CT for 1 to 2 cm solid indeterminate pulmonary nodules.

Objectives: Among the nodule types, the most controversial group are indeterminate solid nodules from 1 to 2 cm in size with the first choice being transthoracic needle biopsy (TTNB) or positron emission tomography (PET-CT) or both methods together. However, no single diagnostic algorithm could be applied to all cases. This research discusses the diagnostic success of PET-CT and TTNB.
