abstract = {Harnessing the immune system by checkpoint blockade has
greatly expanded the therapeutic options for advanced
cancer. Since the efficacy of immunotherapies is influenced
by the molecular make-up of the tumor and its crosstalk with
the immune system, comprehensive analysis of genetic and
immunologic tumor characteristics is essential to gain
insight into mechanisms of therapy response and resistance.
We investigated the association of immune cell contexture
and tumor genetics including tumor mutational burden (TMB),
copy number alteration (CNA) load, mutant allele
heterogeneity (MATH) and specific mutational signatures
(MutSigs) using TCGA data of 5722 tumor samples from 21
cancer types. Among all genetic variables, MutSigs
associated with DNA repair deficiency and AID/APOBEC gene
activity showed the strongest positive correlations with
immune parameters. For smoking-related and UV-light-exposure
associated MutSigs a few positive correlations were
identified, while MutSig 1 (clock-like process) correlated
non-significantly or negatively with the major immune
parameters in most cancer types. High TMB was associated
with high immune cell infiltrates in some but not all cancer
types, in contrast, high CNA load and high MATH were mostly
associated with low immune cell infiltrates. While a bi- or
multimodal distribution of TMB was observed in colorectal,
stomach and endometrial cancer where its levels were
associated with POLE/POLD1 mutations and MSI status, TMB was
unimodal distributed in the most other cancer types
including NSCLC and melanoma. In summary, this study
uncovered specific genetic-immunology associations in major
cancer types and suggests that mutational signatures should
be further investigated as interesting candidates for
response prediction beyond TMB.},
