Association and prognostic significance of BRCA1/2-mutation status
with neoantigen load, number of TIL and expression of PD-1/PD-L1 in
high grade serous ovarian cancer
Kyle C. Strickland et al. Oncotarget 2016
HR deficient tumors, either BRCA1/2-mut or non-
BRCA1/2-mut, demonstrated significantly higher
neoantigen loads than HR proficient tumors
Lower neoantigen load is associated with
inferior overall survival

Damage Associated
Mollecular Patterns
DAMPs
Which would be the (immune) Achilles heel of BRCAmut BC?
i. Extremely sensitive to DNA damaging agents- platinum salts
(especially high score HRD)- immunogenic cell death
ii. Higher mutational load than other non-hereditary BC??- higher
sensitivity to immune checkpoint inhibitors
iii. Neoantigen load and PARP inhibitors effect over immune
microenvironment unknown by now
iv. Why not testing combos with CT (platinum salts) + immune-checkpoint
inhibitors???...

Biomarkers, biomarkers, biomarkers…
Closing remarks and future perspectives TILs as emerging predictive and prognostic factor in BC
Immune gene signatures may complement TILs information
First data with anti-PD1/anti-PD-L1 mAbs in BC promising especially
in TNBC PD-L1+
Immune combos with chemotherapy may have synergistic effects
BRCA+ related to HRD: higher sensitivity to platinum
Molecular features leading to immunogenicity in hereditary BC to be
determined (mutational load, neoantigen load, TILs, PD1/PD-L1…)
Immunotherapy in hereditary BC will probably play a role but most
certainly in the context of combos and hopefully with biomarkers
