Jan 22, 2025 · The ROS1 gene is altered in about 1-2% of patients with lung cancer and generally appears in adenocarcinoma non-small cell lung cancer. Patients who are ROS1-positive tend to be younger than the average patient with lung cancer and have little to no smoking history.

ROS1 is a receptor tyrosine kinase (encoded by the gene ROS1) with structural similarity to the anaplastic lymphoma kinase (ALK) protein; it is encoded by the c-ros oncogene and was first identified in 1986. [7][8][9][10] The exact role of the ROS1 protein in normal development, as well as its normal physiologic ligand, have not been defined. [8] .

A ROS1-positive lung cancer, also known as a ROS1 rearrangement in lung cancer, refers to any lung cancer that tests positive for a fusion in the ROS1 gene. ROS1 rearrangements occur in approximately 1-2% of patients with non-small cell lung cancer (NSCLC). ROS1-positive lung cancer tends to be aggressive and can spread to the brain and the bones.

Feb 3, 2024 · ROS1 positive lung cancer is an aggressive form of lung cancer that often spreads quickly. New, targeted medications can help keep this type of lung cancer from progressing for a period of time, providing a better prognosis today compared to previous generations.

This review summarizes current knowledge on ROS-1 rearrangement in NSCLCs, including the mechanisms responsible for ROS-1 oncogenicity, epidemiology of ROS-1-positive tumors, methods for detecting rearrangement, phenotypic, histological, and molecular characteristics, and their therapeutic management. Much of this work is devoted to resistance ...

The ROS1 (c-ros oncogene 1) gene is located at 6q22 on the long arm of chromosome 6. ROS1 has been described as an ‘orphan’ receptor tyrosine kinase and has no known ligand. The protein product of the gene is a member of the insulin receptor family and is related to ALK.

ROS1 is the oncogene product of the avian sarcoma RNA tumour virus 2 – 4 that encodes a transmembrane tyrosine kinase receptor from the insulin receptor subfamily, and has high homology with the intracellular kinase domain and ATP binding site of ALK.

Rearrangements of the ROS1 gene occur in 1–2 % of non-small cell lung cancers (NSCLCs). Crizotinib, a highly effective inhibitor of ROS1 kinase activity, is now FDA-approved for the treatment of patients with advanced ROS1 -positive NSCLC. Consequently, focus on ROS1 testing is growing.
