Extensive clinical data, including tumor histologic cell type, stage at presentation, treatment, and SUVmax values in the primary tumor were recorded and survival was examined.ResultsTotal 142 patients were included the study. 32 patients of them have stage I and II. The median SUVmax of early stage patients is determined 13.5. Early stage patient population was subdivided into two groups according to the median value for survival. The median survival of the 17 patients with the primary tumor having an SUVmax ≤ 13.0 was 32.5 months whereas the median survival of the 15 patients with the primary tumor having an SUVmax > 13.0 was 19.0 months. There was no stastistical differences between two groups (p=0.463). The 110 patients were on advanced stage (stage III and 4). Using the median SUVmax of 12.5, the patient population was subdivided in two groups. The median survival of the 54 patients with the primary tumor having an SUVmax ≤ 12.5 was 12.0 months whereas the median survival of the 56 patients with the primary tumor having an SUVmax > 12.5 was 11.0 months. There was no stastistical differences between two groups (p=0.236).Conclusion18-FDG SUVmax uptake of the primary lesions in patients with a new diagnosis of NSCLC does not have a significant relationship with survival.
