Episode notes
Exceptional Responders to ALK Inhibitors
- Some patients exhibit remarkable and long-lasting responses to ALK inhibitors, with cases lasting over a decade.
- Identifying these exceptional responders is an ongoing scientific goal despite tissue sample limitations.
Avoid Stopping ALK Therapy
- Stopping ALK therapy is generally avoided due to inevitable disease recurrence.
- Fertility concerns can prompt breaks but require careful consideration, especially in aggressive or dual-resistant disease.
ctDNA Limitations for ALK Detection
- Cell-free DNA tests have lower sensitivity for ALK fusions than for point mutations due to genomic complexity.
- Combining assay methods and tumor-informed approaches may improve minimal residual disease detection.
