Abstract

With the development of cancer immunotherapy that may activate T cells, a practical and quantitative method to improve monitoring and/or prediction of immunological response of patients as a predictive biomarker is of importance. To examine possible biomarkers for a therapeutic cancer vaccine containing a mixture of three epitope peptides derived from cell division‑associated 1, lymphocyte antigen 6 complex locus K and insulin‑like growth factor‑II mRNA‑binding protein 3, T‑cell receptor β (TCRβ) repertoires of blood samples from 24 patients with human leukocyte antigen‑A*2402‑positive non‑small cell lung cancer were characterized prior to and following 8 weeks of the cancer vaccine treatment, by applying a next‑generation sequencing method. It was identified that 14 patients with overall survival (OS) times of ≥12 months had significantly lower TCRβ diversity indexes in samples prior to treatment, compared with 10 patients who succumbed within 1 year (P=0.03). In addition, patients with a high level of activated CD8+ T cells that are defined by a high granzyme A/CD8 ratio had favorable OS rates (log‑rank test, P=0.04). The TCRβ diversity index and immunogenic gene markers following vaccine administration may serve as predictive or monitoring biomarkers for cancer vaccine treatment.
