Finding the right biomarker for renal cell carcinoma (RCC): Nivolumab treatment induces the expression of specific peripheral lymphocyte microRNAs in…
2019
Abstract Background The variability of clinical response to immune checkpoint inhibitors in RCC patients makes necessary the discovery of predictive biomarkers for patient selection. Emerging evidence has revealed a multitude of silenced genes and deregulated signalling pathways. These findings point towards extensive microRNAs (miRNAs) regulation and imply epigenetic reprogramming as a key feature of RCC. The aim of this study was to analyze the peripheral lymphocyte miRNA expression profile in metastatic RCC patients undergoing nivolumab treatment, to identify a lymphocyte miRNA signature specifically expressed in patients with partial or complete response (RP; RC) >12 months. Methods miR…
Prognostic significance of circulating PD-1, PD-L1, pan-BTN3As and BTN3A1 in patients with metastatic gastrointestinal stromal tumours (mGISTs)
2019
Abstract Background Gastrointestinal stromal tumours (GISTs) account for 1% of all primary gastrointestinal cancers. In cancer, suppressive immune checkpoints, including butyrophilin sub-family 3A/CD277 receptors (BTN3A), programmed death protein (PD-1) and its ligand PD-L1, are often hyper-activated to ensure an effective evasion of tumor cells from immune surveillance. Since recent studies showed that PD-1 and PD-L1 expression in cancer may be an important prognostic factor, the aim of our study was to investigate if soluble forms of inhibitory immune checkpoints can help predict survival in metastatic GIST patients. Methods Using specific homemade ELISA assays not yet commercially availa…
