ROS1 rearranged non-small cell lung cancer brain metastases respond to low dose radiotherapy

Abstract

We present a young woman with ROS1 gene rearranged non-small cell lung cancer (NSCLC) with brain metastases. ROS is a proto-oncogene tyrosine protein kinase. The patient received a partial course of whole brain radiation therapy and experienced a sustained partial response in the brain. We hypothesize that ROS1 rearranged NSCLC brain metastases may be particularly sensitive to radiation therapy.

Keywords: Brain metastases; Crizotinib; Non-small cell lung cancer; ROS1; Radiotherapy.
