Salivary IL-6 and Interleukin Gene Polymorphisms in Oral Squamous Cell Carcinoma (IL6-OSCC)
Salivary Interleukin-6 Levels and Interleukin Gene Polymorphisms for the Biological Stratification of Locoregional Progression in Oral Squamous Cell Carcinoma (OSCC): A Multicentre Observational Cross-Sectional Study
This observational study will evaluate whether salivary interleukin-6 levels and selected interleukin gene polymorphisms are associated with regional lymph node involvement in patients with oral squamous cell carcinoma.
Adult patients with histologically confirmed oral squamous cell carcinoma will be enrolled before receiving any cancer-specific treatment. Participants will be classified into two groups according to the presence or absence of regional lymph node metastasis: OSCC N0M0 and OSCC N+M0.
The study does not involve any experimental treatment and does not change the standard diagnostic or therapeutic pathway. Each participant will provide a saliva sample using a sterile absorbent swab. The saliva sample will be used to measure interleukin-6 levels. Available biological material will also be used to analyze selected interleukin gene polymorphisms, including IL6, IL1B, IL10, IL8/CXCL8, and IL1RN.
The aim of the study is to explore whether these salivary and genetic markers may help characterize different biological patterns of locoregional progression in oral squamous cell carcinoma.
연구 개요
상세 설명
Oral squamous cell carcinoma is characterized by variable biological behavior, including different patterns of regional lymph node involvement. Regional lymph node metastasis is one of the main prognostic factors in this disease. However, patients with similar clinicopathological characteristics may show different patterns of locoregional progression, suggesting that additional biological markers may help describe tumor behavior.
This multicentre observational cross-sectional study will investigate salivary interleukin-6 and selected interleukin gene polymorphisms in adult patients with histologically confirmed oral squamous cell carcinoma. Participants will be enrolled before any cancer-specific treatment and classified according to regional lymph node status as OSCC N0M0 or OSCC N+M0.
Saliva will be collected using a standardized sterile absorbent swab procedure. Salivary interleukin-6 levels will be quantified and expressed as pg/mL. Selected interleukin-related genetic polymorphisms, including IL6, IL1B, IL10, IL8/CXCL8, and IL1RN, will be analyzed from available biological material using validated molecular biology methods.
The primary objective is to compare salivary interleukin-6 levels between patients without regional lymph node metastasis and patients with regional lymph node metastasis. Secondary objectives include evaluating the association between nodal status and interleukin gene polymorphisms, and exploring the relationship between these polymorphisms and salivary interleukin-6 levels.
No experimental treatment will be administered, and participation will not modify the standard diagnostic or therapeutic management of oral squamous cell carcinoma.

Association Between Regional Lymph Node Status and Interleukin Gene Polymorphisms
기간: Baseline, before any OSCC-specific oncological treatment
|
The association between regional lymph node status and selected interleukin gene polymorphisms will be evaluated by comparing genotype and/or allele frequencies of IL6, IL1B, IL10, IL8/CXCL8, and IL1RN between patients with OSCC N0M0 and patients with OSCC N+M0.
Where appropriate, results will be expressed as odds ratios for regional lymph node metastasis.
