Abstract

The exclusion of mediastinal involvement in patients with non-small cell lung cancer is essential for choosing an appropriate therapy. The aim of the study was to analyze the ability of a new minimally invasive strategy combining positron emission tomography (PET), endobronchial ultrasound needle aspiration (EBUS-NA), and endoscopic ultrasound needle aspiration (EUS-NA) to exclude mediastinal nodal metastases of non-small cell lung cancer. In a group of consecutive patients with primary non-small cell lung cancer, the preoperative assessment of medisastinal lymph nodes using PET, EBUS-NA, and EUS-NA. Patients in whom this minimally invasive staging protocol did not confirm mediastinal nodal metastases underwent pulmonary resection with systematic lymph node dissection. The negative predictive values of the combined EBUS-NA/EUS-NA as well as PET/EBUS -NA/EUS-NA were calculated. We analyzed data of 532 patients (367 men and 165 women; mean age, 65 years [range, 30-84 years]). Squamous carcinoma were diagnosed in 276 patients; adenocarcinoma, in 150; large cell carcinoma, in 22; adenosquamous carcinoma, in 40; small cell carcinoma, in 4; carcinoids, in 21; and other histological types, in 19. We performed 421 lobectomies, 55 pneum...Continue Reading
