Differences in the dialogue between tumor cells and the cells of their microenvironment have a substantial impact on the clinical outcomes observed in head and neck squamous cell carcinoma (HNSCC). CD8+ T cells and macrophages, acting as effector cells within the immune system, directly kill and phagocytose tumor cells. The relationship between the evolution of their roles in the tumor microenvironment and its clinical impact on patients is currently a mystery. This investigation seeks to explore the intricate communication networks within the HNSCC tumor immune microenvironment, unraveling the interactions between immune cells and the tumor, and formulating a prognostic risk model.
Publicly available databases provided access to 20 head and neck squamous cell carcinoma (HNSCC) samples, including data for both single-cell RNA sequencing (scRNA-seq) and bulk RNA sequencing (bulk RNA-seq). The cellchat R package was applied to identify cell-to-cell communication networks and genes associated with prognosis, and subsequently, cell-cell communication (CCC) molecular subtypes were constructed through unsupervised clustering. A multifaceted approach included analyses of Kaplan-Meier survival, clinical characteristics, immune microenvironment composition, immune cell infiltration profiles, and correlations with CD8+ T cell differentiation. After analyzing the various genes, the ccc gene signature, including APP, ALCAM, IL6, IL10, and CD6, was built through a combination of univariate Cox analysis and multivariate Cox regression. Kaplan-Meier and time-dependent ROC analyses were respectively employed to assess the model's performance in the training and validation cohorts.
In HNSCC cases, a notable reduction in CD6 gene expression within CD8+T cells, as they shift from a naive to an exhausted phenotype, is significantly correlated with poorer patient outcomes. Tumor-associated macrophages (TAMs), characteristic of the tumor microenvironment, contribute to tumor growth and proliferation, enabling tumor cells to acquire essential nutrients. This crucial process also supports tumor cell invasion and metastasis. Subsequently, from the comprehensive evaluation of all ccc factors present in the tumor microenvironment, we delineated five prognostic ccc gene signatures (cccgs), identified through independent univariate and multivariate analysis as critical prognostic markers. The predictive potential of cccgs was markedly apparent in different clinical groups, evaluated in both training and testing sets.
This study emphasizes the frequent interaction between tumor cells and neighboring cells, and established a unique signature derived from a strongly correlated gene associated with cell-cell communication, which possesses substantial predictive power for patient prognosis and immunotherapy effectiveness in HNSCC. The identification of diagnostic biomarkers for risk stratification and therapeutic targets for innovative therapies might be aided by the provided guidance.
This study elucidates the frequency of communication between tumor cells and other cells, establishing a novel signature based on a strongly associated gene for cell signaling that effectively forecasts patient prognosis and immunotherapy response in head and neck squamous cell carcinoma patients. The identification of diagnostic biomarkers for risk stratification and therapeutic targets for novel therapeutic strategies might benefit from this insight.
