5 compelling clinical trials presented in San Diego

In this edition of Clinical Quandaries, Ramalingam et al present a 67-year-old man who seeks care for a new, asymptomatic left upper lobe lung mass, which was found incidentally on a routine chest x-ray as part of a preoperative work-up for an elective surgery. Further staging studies included a computed tomography (CT) scan of the chest and a positron-emission tomography (PET) scan followed by a magnetic resonance imaging (MRI) scan of the liver. Pathology from a fine-needle aspiration biopsy of the left lingular lesion was consistent with poorly differentiated adenocarcinoma and immunohistochemical stains consistent with a lung primary. The left lingular lesion and the prevascular lymph node were felt to be the only sites of involvement, making this stage IIIA (T1, N2, M0) lung cancer.
