[Predictive value of the early metabolic response in patients with advanced-stage non-small cell lung cancer].

Fig. 1. Maximum intensity projection PET images. Axial fused PET/CT images. (A) Initial study. Increased uptake of F-FDG (SUVmax 7.6) in the nodule located in the anterior segment, upper lobe of the left lung (1). Radiotracer uptake in subcarinal adenopathy (SUVmax 9.1) related to tumor involvement (2). Heterogeneous metabolic activity in the left pleura, more intense in the middle posterior region (SUVmax 11.6) related to tumor implants (3). (B) Early response assessment (one month). Resolution of the initial metabolic activity in the nodule located in the left upper lobe of the lung (1), in the subcarinal adenopathy (2), and in the middle posterior pleural implant (3). An early complete metabolic response is observed.
