Although interleukin (IL) 17A can promote angiogenesis in several tumors, there are limited clinical evidences on cancer about the correlation between serum vascular endothelial growth factor (VEGF) and IL-17F, which is the most homologous to IL-17A. In this study, serum concentration of IL-17F and VEGF from healthy (n = 28), leukoplakia (n = 15), and oral squamous cell carcinoma (OSCC) groups (n = 85) were assessed and showed that IL-17F level was remarkably downregulated from healthy group (394.3 pg/ml) to OSCC group (82.96 pg/ml). Conversely, the OSCC group had a highest level of VEGF (P < 0.05) in whole groups, and there was a negative correlation between IL-17F and VEGF in serum or in the peripheral blood mononuclear cells (PBMCs) at mRNA level. Moreover, the lowest ratio of IL-17F/VEGF was found in OSCC patients (P < 0.05) and lower ratio of IL-17F/VEGF correlated to higher tumor stage and lymph node metastasis. Furthermore, the serum level of IL-17F and the ratio of IL-17F/VEGF were positively associated with the numbers of CD3(+) CD4(+) T cells, which indicated that serum IL-17F could originate from PBMCs during the development of OSCC, and could be used for the diagnosis by effectively distinguishing OSCC patients from healthy individuals.

Poor oral health is an independent risk factor for upper-aerodigestive tract cancers, including esophageal squamous cell carcinoma (ESCC); thus, good oral health may reduce the risk of ESCC. We previously reported that high expression of Toll-like receptor (TLR) 6, which recognizes peptidoglycan (PGN) from Gram-positive bacteria correlates with a good prognosis after esophagectomy for ESCC. Most beneficial bacteria in the mouth are Gram-positive.

Objectives: Head and neck malignancies (HNMs) encompass a variety of cancers that affect the oral and para-oral tissues, the most common of which are squamous cell carcinomas. Radiotherapy is commonly used to treat these cancers, often involving radiation exposure to the salivary glands. This study aims to investigate the early impacts of radiotherapy on the internal microstructure of the salivary gland cells and identify which gland exhibits the highest level of radiosensitivity.

Background: The Naples prognostic score (NPS) and its relation to the prognosis of oral squamous cell carcinoma (OSCC) have been inconclusive. This study aimed to investigate the correlation between NPS and the prognosis of postoperative OSCC patients. Additionally, the study sought to develop a new nomogram for predicting disease-free survival (DFS) and overall survival (OS).

Background: We explored the interaction between the oral microbiome and the development of radiation-induced mucositis in patients with head and neck squamous cell cancer (HNSCC) undergoing chemoradiotherapy (CRT). We prospectively studied the oral microbiome and compared it to healthy controls. Additionally, we compared patients with low-grade (LGM) vs.

Background: Oral squamous cell carcinoma (OSCC) is one of the most prevalent oral cancers in the world. The major etiological factors are considered to be tobacco and alcohol. However, the etiological factors for non-habit associated oral squamous cell carcinoma (NHOSCC) remains an enigma.
