Goal • The aim of this study was to find out whether maximum standardized uptake value (SUVmax) can predict survival in surgically staged or resected non-small cell lung cancer (NSCLC) patients. Turkish ThoracicSociety 13. Annual Congress, 5-9 May 2010, Istanbul

Conclusion (4) • Conclusion: Current evidence suggests that increasing tumor FDG uptake is associated with worse survival in patients with stage I NSCLC. FDG uptake has the potential to be used as a biomarker for identifying stage I patients who are at increased risk of death or recurrence and therefore could identify candidates for participation in future trials of adjuvant therapy.

Conclusion (5) • The SUVmax of a pulmonary nodule on PET/CT scanning is an independent predictor of an NSCLC’s biologic aggressiveness or its in vivo virulence. • SUVmax predicted survival in patients with NSCLC staged according to new staging system • Prospective trials of adjuvant chemotherapy in patients with early stage NSCLC and high SUVmax should be considered.
