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.

Cabozantinib has been shown to have potent anti-ROS1 activity in many solid malignancies, particularly against those with solvent-front resistance mutations following crizotinib therapy. With regard to the most common CD74-ROS1 fusion, the efficacy of cabozantinib has only been demonstrated in vitro. Therefore, we evaluate the efficacy of cabozantinib in a patient with advanced non-small-cell lung cancer (NSCLC) harboring a CD74-ROS1 fusion in the present study. A 40-year-old female patient presented with 1-month history of cough, white sputum and chest pain. Chest CT scan revealed a consolidation in the middle lobe of the right lung together with multiple cavity lesions spreading in both lungs. Histopathological analysis of biopsy samples from the lesion in the middle lobe of the right lung suggested lung adenocarcinoma. After two lines of chemotherapy and EGFR-TKI therapy, a CD74-ROS1 rearrangement was detected and the patient was administered with cabozantinib for 1.5 years. Since cabozantinib resistance developed, crizotinib therapy was applied and demonstrated clinical effectiveness until now. Together, we report the first case of cabozantinib effectiveness in treating a CD74-ROS1-positive advanced NSCLC patient. Crizotinib remained as an effective therapeutic option following the acquisition of cabozantinib resistance.

Miliary lung metastases are a rare form of metastasis of non-small-cell lung carcinoma. Miliary lung metastases commonly develop in lung adenocarcinoma with epidermal growth factor receptor mutation. In the present study, we present a case of miliary lung metastases from lung adenocarcinoma with ROS1 rearrangement. The patient, who had a history of surgery for stage IIIA lung adenocarcinoma, presented to our hospital with cough, dyspnea, and severe hypoxia. Chest computed tomography showed numerous tiny, randomly distributed nodules throughout both lungs. No metastases were observed in other organs. Molecular profiling of the surgical specimens was positive for ROS1 rearrangement. The results suggest that chest physicians should be aware that miliary lung metastases can develop in patients with lung adenocarcinoma with ROS1 rearrangement.
