PET-CT has low specificity for mediastinal staging of non-small-cell lung cancer in an endemic area for tuberculosis: a diagnostic test study (LACOG 0114).

Background: The present study aims to assess the performance of 18F-FDG PET-CT on mediastinal staging of non-small cell lung cancer (NSCLC) in a location with endemic granulomatous infectious disease.

Methods: Diagnostic test study including patients aged 18 years or older with operable stage I-III NSCLC and indication for a mediastinal lymph node biopsy. All patients underwent a 18F-FDG PET-scan before invasive mediastinal staging, either through mediastinoscopy or thoracotomy, which was considered the gold-standard.

Retrograde orotracheal intubation with a double-lumen tube.

Background And Objectives: Difficult airway management in thoracic surgeries is a peculiar subject due to the demands of monopulmonary ventilation with double-lumen tubes. Flexible bronchoscopy guidance is extremely important, but it is not always available. The objective of this report was to describe a case of retrograde selective orotracheal intubation in the absence of specific endoscopy equipment for the procedure.

[Concordance between clinical and pathological staging in patients with stages I or II non-small cell lung cancer subjected to surgical treatment].

Objective: To compare clinical and pathological staging in patients with non-small cell lung cancer submitted to surgical treatment, as well as to identify the causes of discordance.

Methods: Data related to patients treated at the Department of Thoracic Surgery of the Pontifical Catholic University of Rio Grande do Sul São Lucas Hospital were analyzed retrospectively. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy were calculated for clinical stages IA, IB, and IIB.
