Lymph node involvement in T1 non-small-cell lung cancer: could glucose uptake and maximal diameter be predictive criteria?☆

Abstract

The low probability of lymph node involvement in NSCLC <1 cm or showing glucose uptake <2 suggests lymphadenectomy could be avoided. A randomized trial should be performed to validate our data.

Recent Progress in Positron Emission Tomography Concerning Diagnosis and Treatment of Lung Cancer

“…Casiraghi et al analyzed 219 patients with pathologic T1 NSCLC, finding a low probability of lymph node involvement in NSCLC, when the longest dimension of the tumor was less than 1 cm, or when the SUV was less than 2; thus, lymphadenectomy might then be avoided. 8) Veronesi et al studied 97 patients with early-stage clinical N0 lung cancers, obtaining similar results. 9) If we would reconfirm these results in larger studies, we could select limited resection and omit lymphadenectomy for certain patients according to the preoperative FDG-PET/CT.…”

Risk factors for mediastinal lymph node metastasis in non-small-cell lung cancer by PET/CT

“…To our knowledge, numerous studies have described the relationship between nodal SUV and lymph node metastasis [16][17][18], but only a few publications have reported the relationship between the SUV of primary lung cancer lesions and node involvement. It was reported that maximum SUV (SUV max ) of the primary Supplemental digital content is available for this article.…”

T1-2NOMO Kucuk Hucreli Disi Akciger Kanseri Hastalarinda Primer Tumor Metabolik Aktivitesi Gizli Lenf Nodu Metastazi için Risk Faktoru mudur ?

“…Değişik çalışmalarda gizli lenf nodu metastazı için risk faktörleri farklı bildirilmektedir. Bu nedenle operable KHDAK hastalarında operasyon öncesi lenf nodlarının değerlendirilmesi için histopatolojik inceleme gerekebilmektedir (6)(7)(8)(9)(10).…”
