Reed-Sternberg cells (malig cell in Hodgkin) strongly express PDL1 due to amplification of 9p24 which contains the PDL1 & PDL2 locus. An exuberant microenvironment includes plenty of PD1+ T-cells and other immune cells. (fig: Roemer et al, JCO 2018) (@graham74GC)

PD-1 blockades doesn't seem to work in DLBCL [Ansell. JCO. 2019.] Perhaps better patient selection like our solid tumor colleagues? High TMB? PD-L1 expression? PD-L1 amplification? PD-L1 translocations? Anything I am missing @Dr_R_Kurzrock (@AaronGoodman33)

The updated ORR and PFS are presented here, noting an increase in ORR. Difference seems amplify with PD-L1 overexpression. Surprising - why should PD-L1 lead to TIGIT working better. I would note that the ORR to atezolizumab alone in this group seems low. #ASCO20 #LCSM (@Jbauml)

PD-L1 gain/amplification as biomarker for #TNBC selection to IO Few patients, but encouraging OS benefit for patients in durvalumab cohort 👉Efficacy of IO also observed in other tumors 👉Can PD-L1 amplification be an agnostic biomarker for IO? @FAndreMD @myESMO @OncoAlert (@antoniomarraMD)

The #overallsurvival spread here according to PDL1/CD274 gain/amplification is impressive. I think we can all agree PDL1 testing alone is likely not the ideal bio marker- this should be examined further. #SAFIR02 #ESMOBreast20 @OncoAlert #bcsm (@ErikaHamilton9)
