Special Issue Information

Dear Colleagues,

This Special Issue, “Genetic Analysis and Clinical Therapy in Head and Neck Cancers”, aims to provide a comprehensive platform for researchers and clinicians to explore the intricate relationship between genetic factors and clinical therapeutic approaches in the context of head and neck cancers. As advances in genomic research continue to unravel the complexities of cancer biology, understanding the genetic underpinnings of head and neck cancers has become crucial for developing targeted and personalized treatment strategies. This Special Issue invites contributions that bridge the gap between genetic insights and clinical applications, fostering a deeper understanding of the molecular mechanisms driving these cancers and facilitating the translation of genetic knowledge into effective therapeutic interventions. Join us in advancing the frontiers of knowledge in head and neck cancer research, with a focus on integrating genetic analysis into clinical practice.

Dr. Alfonso Scarpa

Objectives: Head and neck squamous cell carcinoma (HNSCC) is characterized by complex genetic alterations. This study aimed to identify WBP5 as a promising therapeutic target and evaluate the effect of WBP5 expression on prognosis and treatment response in HNSCC. Methods: Publicly available datasets were comprehensively analyzed to investigate WBP5 expression through comprehensive bioinformatics analysis and functional validation. Results: WBP5 was particularly overexpressed in HNSCC, as analyzed through the Gene Expression Profiling Interactive Analysis version 2 (GEPIA2) database and validated using multiple Gene Expression Omnibus (GEO) datasets. Analysis with UALCAN confirmed that WBP5 expression was significantly higher in advanced cancer stages and tumor grades than that of normal samples. A Kaplan–Meier analysis demonstrated that patients overexpressing WBP5 had a poor prognosis. Moreover, WBP5 expression correlated with the overexpression of the epidermal growth factor receptor in HNSCC. In vitro experiments revealed that WBP5 knockdown significantly reduced FaDu cell proliferation and viability. Furthermore, silencing WBP5 enhanced cisplatin sensitivity, indicating its potential role in chemoresistance. Conclusions: These results indicate that WBP5 could act as a prognostic marker and a viable therapeutic target in HNSCC. Modulating WBP5 expression may represent a novel strategy to enhance treatment efficacy. Future studies should elucidate the precise mechanisms of WBP5 action and develop targeted therapies. This integrated approach, combining a comprehensive analysis of publicly available datasets with in vitro experimental validation provides strong evidence for the clinical significance of WBP5 in HNSCC.

Background/Objectives: Studies have shown that dose to the parotid gland stem cell rich (SCR) regions should be reduced to lower the risk of xerostomia after radiotherapy (RT). This study aimed to assess whether stem cell sparing (SCS)-RT can be adopted in routine clinical practice. Methods: Multiple planning studies were performed to compare SCS-RT with standard (ST)-RT using 30 head and neck cancer patients. Shifts in mean dose to the SCR regions (Dmean,SCR) and other organs at risk and their estimated impact on normal tissue complication probability (NTCP) for side-effects were compared using Wilcoxon signed-rank test. A multicenter study was performed (eight institutions, three patients) to test the generalizability of SCS-RT using the Friedman test. Results: Using photons, Dmean,SCR was reduced with median 4.1/3.5 Gy for ipsilateral/contralateral (p < 0.001). The largest reductions were when the SCR regions overlapped less with target volumes. Subsequently, NTCPs for xerostomia decreased (p < 0.001). Using protons, Dmean,SCR was also reduced (2.2/1.9 Gy for ipsilateral/contralateral, p < 0.002). Nevertheless, SCS-RT did not further decrease NTCPs for xerostomia (p > 0.17). Target coverage and prevention of other side-effects were not compromised. However, increased mean oral cavity dose was observed in some patients. Lastly, in the multicenter study Dmean,SCR could be reduced by slightly adjusting the standard optimization. Contralateral Dmean,SCR reductions differed between centers (p = 0.01), which was attributed to differences in ST-RT plans. Conclusions: Stem cell sparing radiotherapy can be clinically introduced by making small adjustments to the optimization strategy and can reduce the risk of xerostomia. Full article
