Risk factors for local and nodal recurrence in patients with head and neck cutaneous squamous cell carcinoma in a high-reference oncological center in Poland.

Background: The behavior of cutaneous squamous cell carcinoma (cSCC) of the head and neck remains poorly understood. There is much controversy regarding the risk of local and nodal recurrences, as well as individual/environmental factors that increase the risk, such as tumor size, perineural invasion, and the state of the immune system. The objective was to analyze factors influencing local and/or regional lymph node recurrence in patients with cSCC in the head and neck region.

The impact of XPC gene single nucleotide polymorphism rs2228001 on head and neck cancer patients' response to radiotherapy treatment.

Background: Head and neck squamous carcinoma (HNSC) is the sixth most common neoplasm, with a 40-50% overall survival rate. HNSC standard treatment depends on tumor size, metastasis or human papillomavirus (HPV) status including surgery, chemotherapy, and radiotherapy. The last two may lead to defects in the tumor microenvironment and cancer cell biology as disorders in DNA damage repair systems.

Improving therapeutic strategies for Head and Neck Cancer: Insights from 3D hypoxic cell culture models in treatment response evaluation.

Hypoxia in the tumor core negatively affects the outcome of patients with head and neck squamous cell carcinoma (HNSCC). Nevertheless, its role in predicting treatment response requires further exploration. Typically, reduced oxygen levels in the tumor core correlate with diminished efficacy of radiotherapy, chemotherapy, and immunotherapy, which are commonly used for HNSCC patients' treatment.

The two-faced role of RNA methyltransferase METTL3 on cellular response to cisplatin in head and neck squamous cell carcinoma model.

Background: RNA methyltransferase-like 3 (METTL3) is responsible for methyl group transfer in the progression of -methyladenosine (mA) modification. This epigenetic feature contributes to the structural and functional regulation of RNA and consequently may promote tumorigenesis, tumor progression, and cellular response to anticancer treatment (chemo-, radio-, and immunotherapy). In head and neck squamous cell carcinoma (HNSCC), the commonly used chemotherapy is cisplatin.

Understanding Hypoxia-Driven Tumorigenesis: The Interplay of HIF1A, DNA Methylation, and Prolyl Hydroxylases in Head and Neck Squamous Cell Carcinoma.

Hypoxia-inducible factor 1-alpha (HIF1A) is a key transcription factor aiding tumor cells' adaptation to hypoxia, regulated by the prolyl hydroxylase family (EGLN1-3) by directing toward degradation pathways. DNA methylation potentially influences EGLN and HIF1A levels, impacting cellular responses to hypoxia. We examined 96 HNSCC patients and three cell lines, analyzing gene expression of , , , , and at the mRNA level and EGLN1 protein levels.

A Matter of Margins in Oral Cancer-How Close Is Enough?

In patients with oral cancer, the risk factors for local, regional, and distant recurrence according to margin status have not been well established.
