Abstract

HLA genotype affects response: Immunotherapy works by activating the patient's own immune system to fight cancer. For effective tumor killing, CD8 + T cells recognize tumor peptides presented by human leukocyte antigen class I (HLA-I) molecules. In humans, there are three major HLA-I genes ( HLA-A, HLA-B , and HLA-C ). Chowell et al. asked whether germline HLA-I genotype influences how T cells recognize tumor peptides and respond to checkpoint inhibitor immunotherapies (see the Perspective by Kvistborg and Yewdell). They examined more than 1500 patients and found that heterozygosity at HLA-I loci was associated with better survival than homozygosity for one or more HLA-I genes. Thus, specific HLA-I mutations could have implications for immune recognition and for the design of epitopes for cancer vaccines and immunotherapies. Science , this issue p. 582 ; see also p. 516

    In cohort 1, tumor loss of heterozygosity at HLA-I in patients heterozygous at all HLA-I loci was associated with reduced survival.

    “Patients with LOH of HLA-I were associated with reduced survival (P = 0.05, HR = 1.60, 95% CI 1.03 to 2.43) (Fig. 1H).”

  • The authors state this as an assumption.

    Before this study, the extent to which a patient's HLA class I genotype affects response to anti-PD-1 or anti-CTLA-4 therapy was unknown.

    “However, the extent to which patient-specific HLA-I genotype influences response to anti–programmed cell death protein 1 or anti–cytotoxic T lymphocyte–associated protein 4 is currently unknown.”
  • The paper relies on this without support.

    The two study cohorts are representative of advanced cancer patients treated with immune checkpoint blockade, so the observed associations apply beyond these cohorts.

    “We examined two sets of cancer patients (henceforth called cohort 1 and cohort 2) treated with ICB.”
  • The paper relies on this without support.

    The TCGA melanoma cohort is an appropriate untreated comparator for determining whether B44 is prognostic rather than predictive.

    “The B44 alleles did not associate with survival in patients with melanoma from The Cancer Genome Atlas (TCGA), suggesting that the presence of B44 was predictive of response to ICB and was not prognostic (Fig. 2I).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
