简要总结
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.
详细描述
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.

结局指标
主要结局
Difference in Salivary Interleukin-6 Levels Between OSCC N0M0 and OSCC N+M0 Patients
时间窗: Baseline, before any OSCC-specific oncological treatment
Salivary interleukin-6 levels will be compared between patients with oral squamous cell carcinoma without regional lymph node metastasis, classified as OSCC N0M0, and patients with oral squamous cell carcinoma with regional lymph node metastasis, classified as OSCC N+M0. Salivary interleukin-6 will be measured from saliva samples collected using sterile absorbent swabs and expressed as a continuous variable in pg/mL.
次要结局
- Association Between Regional Lymph Node Status and Interleukin Gene Polymorphisms(Baseline, before any OSCC-specific oncological treatment)
- Association Between Interleukin Gene Polymorphisms and Salivary Interleukin-6 Levels(Baseline, before any OSCC-specific oncological treatment)
