The goal of this paper was to investigate the influence of FDG-PET/CT scan on the modification of staging and irradiation planning in patients suffering from non-small cell lung cancer (NSCLC). Fifteen patients suffering from NSCLC were analyzed by the authors from January, 2008 to July, 2009. The aim of the analysis was to examine the influence of FDG-PET/CT on irradiation planning and on decision-making of the complex oncologic therapy. ⋯ We likewise found a decrease in the mean dose load of the heart (17.3 Gy/16.8 Gy) and left ventricle (12.9 Gy/9.6 Gy). In the majority of the cases the FDG-PET/CT scan modified the therapeutic decision, the size of the irradiated volume, and the dose load of the lung, the organ at risk causing the most difficulties at irradiation planning, was also reduced. The PET/CT scan plays an essential role in the complex oncologic treatment and irradiation therapy of NSCLC.
