Introduction: This study aimed to assess the prognostic value of CD8+CD28− T lymphocyte in peripheral blood among breast cancer patients treated with adoptive T lymphocytes immunotherapy.Methods: 217 patients participated in the follow-up study. CD8+CD28− proportion was measured by flow cytometry in peripheral T cells. The median survival was estimated by Kaplan-Meier curve, Log-rank test and Cox hazard proportion regression model, between groups of CD8+CD28− proportion more than 24.2% and less than or equal to 24.2% in peripheral T cells.ResultsThe median follow-up period was 15 months. Median time to progression was 11.8 months among patients with CD8+CD28− proportion less than or equal to 24.2% and 7.1 months among patients with CD8+CD28− proportion more than 24.2% (p<0.05). With further adjustments, CD8+CD28− proportion of more than 24.2% produced a HR being 2.13 (95%CI 1.45, 3.12) for progression. Patients with CD8+CD28− proportion of less than or equal to 24.2% had median overall survival of 36.2 months, 10.6-month longer than patients with higher CD8+CD28− proportion (p<0.05). With further adjustments, CD8+CD28− proportion of more than 24.2% produced a 86% higher risk for death (HR = 1.86, 95%CI 1.07, 3.24).ConclusionPeripheral CD8+CD28− proportion had a negative association with progression-free and overall survival among breast cancer patients receiving adoptive T cell immunotherapy. CD8+CD28− suppressive T cell was a potential biomarker for breast cancer patients’ prognosis.Citation Format: Qingkun Song, Jun Ren, Jing Yu, Xiaoli Wang, Xinna Zhou, Herbert Kim Lyerly.
