In this study, we aim to evaluate the relationship between maximum standardized uptake value (max.SUV) with the primary tumor size and its T-stage as well as patients’ age and sex. In addition, we try to suggest the equations between (max.SUV) and tumor size in patients with non-small cell lung cancer (NSCLC)

Lung cancer is the most commonly diagnosed cancer; of which non-small cell lung cancer (NSCLC) accounting for approximately 80% of newly diagnosed lung cancer. The prognosis of lung tumors depends on early and accurate staging and the histopathological type of the tumor.[1] Although CT scanning has long been the go-to imaging modality to stage lung cancer, it is hindered by many limitations and pitfalls. It may be unable to distinguish a tumor from atelectasis, does not reflect tumoral metabolic activity and gives no idea about...

This cross-sectional study included forty patients, with (nine) females (22.5 %) and 31 males (77.5%). Ages ranged between 35 and 88 years with the mean age of 62.95 years ±10.01SD. The study included (25) 62.5% patients with adenocarcinoma, (12) 30% patients with squamous cell carcinoma and (30) 7.5% patients with large cell carcinoma The (T) staging of the described primary lung masses were: (9) 22.5% with T1, (11) 27.5% with T2, (14) 35% with T3 and (6) 15% with T4 primary mass staging.

Discussion: Computed tomography (CT) of the chest has been the workhorse for establishment of the precise anatomical and morphological information. Though, (FDG) PET/CT acquired an increased dependance for the diagnosis and staging of lung cancer.[7] The metabolic activity represented by (FDG) uptake is now considered to be a prognostic factor in patients with lung cancer [7,8]. Meaning that patients with positive FDG-PET-CT results in treated lung cancer had a significantly worse prognosis than patients with negative results. [9]. In our study, we explore whether max.SUV...
