Figure 10a. Multidisciplinary care of a 44-year-old man with left upper lobe poorly differentiated NSCLC. (a) Transverse CT image at baseline shows a large left upper lobe mass (m) with an adjacent satellite lesion (arrow). (b) Transverse CT image at baseline also reveals a small indeterminate nodule in the right upper lobe (arrow). (c) PET image demonstrates a hypermetabolic mass (m) of the left upper lobe and increased activity in a nodule of the right upper lobe nodule (arrow). Transthoracic needle biopsy of the right upper lobe nodule was positive for poorly differentiated NSCLC. (d) Transverse CT image after induction chemotherapy reveals decrease in left upper lobe mass (m) and resolution of the adjacent satellite nodule. There also is no longer evidence of the right upper lobe nodule. (e) PET image after induction chemotherapy shows the left upper lobe hypermetabolic mass (m) and resolution of activity in the right upper lobe. The patient underwent resection of the left upper lobe mass and radiation therapy in the left upper chest. At a recent follow-up 24 months after initiation of induction chemotherapy, the patient remains free of disease.
