Case Report: Adjuvant Crizotinib Therapy Exerted Favorable Survival Benefit in a Resectable Stage IIIA NSCLC Patient With Novel LDLR–ROS1 Fusion
Novel adjuvant strategies are needed to optimize outcomes after complete surgical resection in patients with early-stage non-small-cell lung cancer (NSCLC). The adjuvant treatment of ROS Proto-Oncogene 1 (ROS1) fusion-positive resected NSCLC is challenging because there is no curative confirmed rand...

Sumario: | Novel adjuvant strategies are needed to optimize outcomes after complete surgical resection in patients with early-stage non-small-cell lung cancer (NSCLC). The adjuvant treatment of ROS Proto-Oncogene 1 (ROS1) fusion-positive resected NSCLC is challenging because there is no curative confirmed randomized controlled trial. Next-generation sequencing (NGS) and immunohistochemistry (IHC) staining were performed on the biopsy sample. In this case, we identified a novel LDLR–ROS1 fusion in a resectable stage IIIA NSCLC patient. The patient received crizotinib as adjuvant treatment and achieved recurrence-free survival (RFS) for 29 months, without significant symptoms of toxicity. In this case, we report a novel LDLR–ROS1 fusion responding to crizotinib in a patient with lung adenocarcinoma, supporting the use of adjuvant treatment with the ROS1 inhibitor exerting clinical survival benefit in ROS1 fusion-positive resected NSCLC. |
