1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract

Adoptive cell transfer (ACT)-based immunotherapies can mediate objective cancer regression in animal models and in up to 70% of patients with metastatic melanoma; however, it remains unclear whether the tumor vasculature impedes the egress of tumor-specific T cells, thus hindering this immunotherapy. Disruption of the proangiogenic interaction of vascular endothelial growth factor (VEGF) with its receptor (VEGFR-2) has been reported to "normalize" tumor vasculature, enhancing the efficacy of chemotherapeutic agents by increasing their delivery to the tumor intersitium. We thus sought to determine whether disrupting VEGF/VEGFR-2 signaling could enhance the effectiveness of ACT in a murine cancer model. The administration of an antibody against mouse VEGF synergized with ACT to enhance inhibition of established, vascularized, B16 melanoma (P = 0.009) and improve survival (P = 0.003). Additive effects of an antibody against VEGFR-2 in conjunction with ACT were seen in this model (P = 0.013). Anti-VEGF, but not anti-VEGFR-2, antibody significantly increased infiltration of transferred cells into the tumor. Thus, normalization of tumor vasculature through disruption of the VEGF/VEGFR-2 axis can increase extravasation of adoptively transferred T cells into the tumor and improve ACT-based immunotherapy. These studies provide a rationale for the exploration of combining antiangiogenic agents with ACT for the treatment of patients with cancer.
