12502 Tumor-reactive CD4 and CD8 memory T cells (MTC) can be found in bone marrow (BM) of the majority of primary and metastatic breast cancer patients. In xenotransplant mouse models these cells, upon specific re-activation ex vivo, mediated efficient rejection of autologous breast tumors suggesting that the polyclonal natural MTC repertoire possesses therapeutic potential. In order to clinically exploit these anti-tumor capacities we treated 11 advanced metastasized breast cancer patients with autologous, tumor-reactive, reactivated MTC of BM in a phase-1 trial. Activation of T cells was done by MCF-7 lysate pulsed dendritic cells (DC). After reactivation both, T cells and pulsed DC were injected once intravenously. Peripheral blood was drawn on day 0, 1, 7, 14, 28. BM-re-aspiration was done on day 28 and 84. While TAA-reactive memory T cells were absent in the peripheral blood (PB) before therapy, 5 from 11 patients (=responders) showed TAA-specific PB T cell reactivity 7 days after therapeutic cell application suggesting a massive proliferation and mobilization into the blood of TAA-reactive T cells in these patients. A comparison of responders to adoptive cellular immunotherapy with non-responders revealed differences in the numbers of therapeutic cells that could be generated ex vivo and in the decreased frequency of tumor-reactive MTC in responders’ BM on days 28 and 84 which could be expained by a mobilization due to in situ activation by co-transferred DCs or due to local or systemic cytokine signals by transferred, activated T lymphocytes. Such effect might have contributed to the high numbers of circulating TAA-reactive T cells observed 7 days after the transfer. Furthermore we observed different concentrations of IL-4, IL-10, TNF-α, and INF-γ in PB and BM between the two groups leading to the hypothesis of a polarization in T cell responses (T1 type in responders vs T2 type in non-responders). No significant financial relationships to disclose.

The rationale for therapeutic targeting of Vδ2+ γδ T cells in breast cancer is strongly supported by in vitro and murine preclinical investigations, characterizing them as potent breast tumor cell killers and source of Th1-related cytokines, backing cytotoxic αβ T cells. Nonetheless, insights regarding Vδ2+ γδ T cell phenotypic alterations in human breast cancers are still lacking. This paucity of information is partly due to the challenging scarcity of these cells in surgical specimens. αβ T cell phenotypic alterations occurring in the tumor bed are detectable in the periphery and correlate with adverse clinical outcomes. Thus, we sought to determine through an exploratory study whether Vδ2+ γδ T cells phenotypic changes can be detected within breast cancer patients’ peripheral blood, along with association with tumor progression. By using mass cytometry, we quantified 130 immune variables from untreated breast cancer patients’ peripheral blood. Supervised analyses and dimensionality reduction algorithms evidenced circulating Vδ2+ γδ T cell phenotypic alterations already established at diagnosis. Foremost, terminally differentiated Vδ2+ γδ T cells displaying phenotypes of exhausted senescent T cells associated with lymph node involvement. Thereby, our results support Vδ2+ γδ T cells implication in breast cancer pathogenesis and progression, besides shedding light on liquid biopsies to monitor surrogate markers of tumor-infiltrating Vδ2+ γδ T cell antitumor activity.

AbstractIn tumor cells, higher expression of glucose transporter proteins (GLUT) and carbonic anhydrases (CAIX) genes is influenced by hypoxia-induced factors (HIF).Thus, we aimed to study the expression profile of these markers in sequential peripheral blood collections performed in breast cancer patients in order to verify their predictive potential in liquid biopsies. Gene expressions were analyzed by qPCR in tumor and blood samples from 125 patients and 25 healthy women. Differential expression was determined by the 2(−ΔCq) method. Expression of HIF-1α and GLUT1 in the blood of breast cancer patients is significantly higher (90–91 and 160–161 fold increased expression, respectively; p < 0.0001) than that found in healthy women. Their diagnostic power was confirmed by ROC curve. CAIX is also more expressed in breast cancer women blood, but its expression was detected only in a few samples. But none of these genes could be considered predictive markers. Therefore, evaluation of the expression of HIF-1α and GLUT1 in blood may be a useful laboratory tool to complement the diagnosis of breast cancer, in addition to being useful for follow-up of patients and of women with a family history of breast cancer.
