Metronomic chemotherapy with prednisone, etoposide, and cyclophosphamide resulted in higher ORR and DCR, fewer adverse effects, and longer PFS in patients with relapsed or refractory NHL, with significant reduction in serum CECs and VEGF levels.
Immune checkpoint blockade (ICB) therapy is a promising treatment for hepatocellular carcinoma (HCC). However, it is limited by low response rates. Tumour‐infiltrating immune cells (TIICs), specifically CD8+ T cells, in the tumour microenvironment (TME) are related to tumour immune responses and are potential predictors for immunotherapeutic and survival outcomes. Therefore, we established a new CD8+ T cell‐related genes prognostic index (CD8T‐RGPI) for evaluating immune responses and prognostic outcomes for HCC. Using the TCGA databases, we evaluated the RNA‐seq data of CD8+ T cell‐related genes with gene co‐expression network. Then, the CD8T‐RGPI model was built by combining univariate Cox regression and the least absolute shrinkage and selection operator (LASSO) Cox regression analyses. The nomogram exhibited a good prediction ability for HCC patients' prognosis in either TCGA or ICGC databases. The CD8T‐RGPI was elevated in patients with high T, M and TNM stages. Functional enrichment analyses revealed that in CD8T‐RGPI high‐risk group, tumour‐related and immunosuppressive pathways, such as focal adhesion, aerobic glycolysis, HIF1 transcription factor pathway, IL‐4 and IL‐13 signalling were significantly enriched. Moreover, for CD8T‐RGPI high‐risk HCC patients, immune tolerance and immunosurveillance escape was associated with poor therapeutic outcomes for ICB therapy. The CD8T‐RGPI low‐risk HCC patients with elevated immune infiltration levels were associated with good immunotherapeutic responses to ICB. Our findings provide prospective prognostic biomarkers and elucidate on HCC immunotherapy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
