Update on nodal staging in non-small cell lung cancer with integrated positron emission tomography/computed tomography: a meta-analysis

Abstract: PET/CT has a high specificity, but low sensitivity for detecting LN metastasis in patients with NSCLC. Tb might be one of the main reasons for lower sensitivity of PET/CT in several countries. The primary clinicians of lung cancer should be aware of the possibility of hidden metastatic LNs in bilateral FDG uptake of mediastinal and hilar LNs, especially in the Tb endemic countries.

“…Although the sensitivity and specificity of imaging techniques for LC staging have improved with the introduction of FDG-PET, the technique lacks sufficient accuracy to guide treatment after the procedure, mainly because its sensitivity and negative predictive value (NPV) for malignancy have shown figures below 80% in most studies [6, 16–18]. Therefore, in accordance with current guidelines a biopsy is still needed to confirm lymph node involvement, except in peripheral lung cancers below 3 cm in diameter and negative results of imaging studies of the mediastinum in which case the probability of malignancy is very low [19–21].…”

“…FDG PET/BT görüntülemenin mediastinal lenf nodu metastazlarını belirlemedeki tanısal doğruluğunu mediastinoskopi ve cerrahi sonuçlarını referans alarak değerlendiren çok sayıda araştırma bulunmakta olup, bu araştırmaların sonuçları çeşitli meta-analizler ile derlenmiştir (23,24,25). Bu çalışmalar FDG PET/BT görüntülemenin duyarlılığının mediastinal lenf nodlarını değerlendirmek için yeterli olmadığını göstermiştir.…”

“…Çapı 1 cm üzerinde olan lenf nodlarında FDG PET/BT görüntülemenin duyarlılığı %85 düzeyinde iken, 1 cm altındaki lenf nodlarında bu değer %32'ye düşmektedir (26). Ayrıca birçok benign hastalıkta (enfeksiyon, sarkoidoz, tüberküloz gibi) lenf nodlarında artmış FDG tutulumu gözlenebilir (23). Bu nedenle FDG tutulumu göstermeyen mediastinal lenf nodlarında metastaz varlığı dışlamayacağı gibi, FDG tutulumu gösteren tüm lenf nodları da metastatik olarak kabul edilmemelidir (3).…”
