Conclusions
•
PD-L1 (imperfect) gold standard to
give
IO.
•
TMB expensive and immature to
give
IO.
–
Better than PD-L1? Better TMB & PD-L1?
Threshold? Platform?
–
High TMB predictive in PD-L1 neg. tumours
•
LIPI, easy score (LDH/neutrophils) to
give
IO.
•
Some groups of patients
not
to
give
IO.
•
Immunotherapy probably does not fit all patients.
