Comprehensive survival analysis of oral squamous cell carcinoma patients undergoing initial radical surgery.

OBJECTIVE: This study was designed to evaluate the five-year overall survival (OS) rate and postoperative survival time of patients diagnosed with oral squamous cell carcinoma (OSCC), as well as examine the clinical and pathological factors influencing survival outcomes in OSCC patients. METHODS: Data were collected from OSCC patients who underwent their first radical surgical intervention in the Department of Maxillofacial Surgery at the First Affiliated Hospital of Chongqing Medical University between April 2014 and December 2016. Follow-up was conducted until March 2022. RESULTS: The study included a total of 162 patients. The observed 5-year OS rate was 59.3%. Approximately 45.7% of OSCC patients experienced postoperative recurrence or metastasis, with a 5-year overall disease-free survival rate of 49.4%. There was no significant difference in the impact of sex, age, smoking, alcohol consumption, primary tumour location, depth of invasion or primary tumour size on the 5-year survival rate (p > 0.05). Univariate analysis revealed that clinical stage (Hazard Ratio = 2.239, p = 0.004), perineural invasion (PNI) (Hazard Ratio = 1.712, p = 0.03), lymph node metastasis (pN) (Hazard Ratio = 2.119, p = 0.002), pathological differentiation (Hazard Ratio = 2.715, p < 0.001), and recurrence or metastasis (Hazard Ratio = 10.02, p < 0.001) were significant factors influencing survival. Multivariate analysis further indicated that pathological differentiation (Hazard Ratio = 2.291, p = 0.001), PNI (Hazard Ratio = 1.765, p = 0.031) and recurrence or metastasis (Hazard Ratio = 9.256, p < 0.001) were independent risk factors of survival. Intriguingly, 11 OSCC patients were diagnosed with oesophageal squamous cell carcinoma (ESCC) within 1-4 years following surgery. CONCLUSION: The survival prognosis of OSCC patients is significantly associated with clinical stage, PNI, lymph node metastasis, pathological differentiation, and recurrence or metastasis. Pathological differentiation, PNI and recurrence or metastasis are independent risk factors affecting survival. Routine clinical screening for ESCC may be recommended for OSCC patients with a history of alcohol consumption and tobacco use.

Association between juvenile idiopathic arthritis and periodontal diseases: a systematic review and meta-analysis.

Although periodontal diseases have been widely reported in patients with juvenile idiopathic arthritis (JIA), their association with JIA remains controversial. This systematic review and meta-analysis aimed to evaluate the association between JIA and periodontal diseases to facilitate oral health management and periodontal disease prevention in JIA patients. We conducted a comprehensive search of Web of Science, Cochrane Library, PubMed, Embase, Chinese Scientific and Technological Journal (VIP) database, Wan Fang Data, China National Knowledge Infrastructure (CNKI), and China Biomedical Literature Database (CBM) up to 30 September 2022, without publication dates or language restrictions. Two authors independently evaluated observational studies for inclusion, and the quality of the included studies was assessed using the Newcastle Ottawa Scale (NOS) and the Agency for Healthcare Research and Quality (AHRQ). Continuous variables are presented as mean difference (MD) and 95% confidence interval (CI). Parameters of the simplified oral hygiene index (OHI-S), plaque index (PI), gingival index (GI), clinical attachment loss (CAL), and probing depth (PD) were considered as outcome measures and were compared between JIA patients and healthy controls. The initial search comprised 15 studies with a total of 1537 individuals. The meta-analysis showed the parameters of OHI-S (MD = 0.12, 95% CI: 0.04-0.19, p = 0.002), PI (MD = 2.08, 95% CI: 1.67-2.50, p < 0.00001), GI (MD = 0.50, 95% CI: 0.17-0.82, p = 0.003), CAL (MD = 0.22, 95% CI: 0.01-0.43, p = 0.04), and PD (MD = 1.42, 95% CI: 0.08-2.77, p = 0.04) in JIA patients were significantly higher than those of healthy controls. All of the included studies were of high quality. This systematic review and meta-analysis showed a possible association between JIA and periodontal diseases. Therefore, it is recommended to continuously pay attention to the periodontal health of JIA patients and fully explore the underlying mechanism.

[Expression and prognostic value of IL-6 and ß-catenin in oral squamous cell carcinoma].

PURPOSE: To investigate the expression of interleukin-6 (IL-6) and ß-catenin in oral squamous cell carcinoma (OSCC) and its clinicopathological significance. METHODS: The serum IL-6 concentration in 110 OSCC patients and 109 healthy controls were determined by chemiluminescence analysis. IL-6 and ß-catenin expression levels in 68 tumor specimens of OSCC patients undergoing surgical treatment and 6 normal mucosal tissues were determined by immunohistochemistry method. The correlation between IL-6 and ß-catenin and clinicopathological parameters and their prognostic value were analyzed. SPSS 22.0 software package was used for data analysis. RESULTS: Chemiluminescence method showed that the serum IL-6 content of OSCC patients was significantly increased (P＜0.001). Immunohistochemical results demonstrated that high expression of IL-6 in OSCC tissues was remarkably associated with cervical lymph node metastasis(P=0.017), pathological differentiation(P=0.014), recurrence and distant metastasis (P=0.048). OSCC patients with high IL-6 expression showed a poor prognosis by Kaplan-Meier survival analysis. Multivariate Cox regression analysis showed that high expression of IL-6 was an independent risk factor affecting the prognosis of patients with OSCC(P＜0.05). ß-catenin hyperexpression was associated with pathological differentiation(P=0.006) and overall poor survival in OSCC patients. Spearman correlation analysis showed a positive correlation between IL-6 and ß-catenin expression in OSCC (P＜0.001). CONCLUSIONS: Serum IL-6 is expected to be a biomarker for detection of OSCC, and IL-6 and ß-catenin expression in tumour tissues can be used as markers to evaluate the poor prognosis of OSCC.
