RESISTANCE TO TYROSINE KINASE INHIBITOR
CASE REPORT
• Lorlatinib resistance to Crizotinib in patient with Cysteine to Tyrosine at (C1156Y).
• Later resistance to Lorlatinib created mutation at L1198F which enabled re-sensitization to Crizotinib.

• Importance of Biomarkers• Rapid testing• Sufficient tissue• Immuno-competent patient• Reduce Hospital Admissions• When not to treat• When to stop treating
Doctors are men who prescribe medicines of which they know little, to cure disease of which they know less, in human beings of which they know nothing
