ROS1-rearranged non-small cell lung carcinoma is a subtype of non-small cell lung carcinoma that can be treated with ALK inhibitors.[1]
General
- ROS1-rearrangements are seen in approximately 1-2% of non-small cell carcinoma.[2]
- Respond to targeted therapy, e.g. crizotinib.[3]
Microscopic
Features:
- Histology not definitive; however, predictive features are:[4]
Note:
- Most common pattern varies by specimen type:[4]
- Biopsy specimens: solid pattern most common.
- Resection specimens: acinar pattern most common.
