The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors' suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice.A 54-year-old man with a former 15-pack-year smoking history presents with cough and dyspnea. Initial work-up with imaging demonstrates a right suprahilar mass measuring 4.7 cm as well as several enlarged hilar and ipsilateral mediastinal lymph nodes. Bronchoscopy with biopsy reveals adenocarcinoma consistent with a lung primary. Staging with positron emission tomography/computed tomography (PET/CT) reidentifies the primary mass and lymph nodes and shows several PET-avid bone metastases. Brain magnetic resonance imaging (MRI) demonstrates a 1.6-cm right parietal mass with mild vasogenic edema and four additional brain metastases measuring 4 to 9 mm in size. Molecular testing is positive for an anaplastic lymphoma kinase (ALK) gene rearrangement using fluorescence in situ hybridization and negative for EGFR, ROS1, RET, BRAF, KRAS, and other oncogenes. The patient denies any neurologic symptoms and has no significant findings on neurologic exam. He is referred to you for management options for newly diagnosed stage IV (T2aN2M1b) lung adenocarcinoma.

Non-small cell lung cancer is a devastating disease and with the advent of targeted therapies and molecular testing, the decision-making process has become complex. While established guidelines and pathways offer some guidance, they are difficult to utilize in a busy community practice and are not always implemented in the community. The rationale of the study was to identify a cohort of patients with lung adenocarcinoma at a City of Hope community site (n = 11) and utilize their case studies to develop a decision-making framework utilizing fast-and-frugal tree (FFT) heuristics. Most patients had stage IV (N = 9, 81.8%) disease at the time of the first consultation. The most common symptoms at initial presentation were cough (N = 5, 45.5%), shortness of breath (N = 3, 27.2%), and weight loss (N = 3, 27.2%). The Eastern Cooperative Oncology Group (ECOG) performance status ranged from 0-1 in all patients in this study. Distribution of molecular drivers among the patients were as follows: EGFR (N = 5, 45.5%), KRAS (N = 2, 18.2%), ALK (N = 2, 18.2%), MET (N = 2, 18.2%), and RET (N = 1, 9.1%). Seven initial FFTs were developed for the various case scenarios, but ultimately the decisions were condensed into one FFT, a molecular stage IV FFT, that arrived at accurate decisions without sacrificing initial information. While these FFT decision trees may seem arbitrary to an experienced oncologist at an academic site, the simplicity of their utility is essential for community practice where patients often do not get molecular testing and are not assigned proper therapy.
