Despite being already known that p27 can regulate cell proliferation, cell motility and apoptosis, the role of p27 expression in oral squamous cell carcinoma (OSCC) remains controversial. The purpose of this study was to comprehensively evaluate, with a meta-analysis, the clinicopathological and prognostic role of p27 expression in OSCC. A meta-analysis of eligible studies was performed to assess the effects of p27 expression on clinicopathological parameters and overall survival (OS) in patients with OSCC, using pooled relative risks with 95% confidence intervals. Heterogeneity and publication bias were also assessed. Fourteen studies involving a total of 1,010 patients met the inclusion criteria. Low p27 expression was significantly associated with advanced TNM stage (p<0.001), worse histology (p=0.025), and lymph node metastasis (p<0.001), but not with tumor size (p=0.181). The pooled RR of 0.743 (p=0.002) suggested that low p27 expression has a poor prognosis in patients with OSCC. A significant heterogeneity among studies was detected for lymph node status (χ2=34.60, I2=68.2%, p<0.001) and OS (χ2=14.86, I2=39.4%, p=0.095). We did not detect a significant publication bias in this meta-analysis. Our meta-analysis suggests that p27 expression status might be useful as a predictive biomarker in clinical practice, and might potently predict OS in OSCC patients.

BACKGROUND Mortality and Morbidity rates in the patients diagnosed with oral cancers remain static despite availability of advanced diagnostic and treatment modalities. For improving the survival status of the patients, a thorough understanding of the factors that predicts the progression of oral cancer is necessary to determine appropriate line of treatment. To do so in practise, critical knowledge regarding the prognostic factors that has high sensitivity holds immense importance. For determination of prognosis in oral cancer patients, clinical and histopathological parameters are widely used for assessment of treatment strategies. The primary objective of this study was to determine the clinical and histopathological prognostic factors in patients of oral squamous cell carcinoma of gingivobuccal sulcus (GBSSCC) treated by surgical intervention (neck dissection). METHODS Histopathological evaluation of archived samples of 60 GBSSCC patients which were treated by surgical intervention (Neck Dissection) in the time period from January 2011 to December 2020. Recurrent cases were excluded. Clinicopathological parameters such as age, sex, habit, tumour site, tumour size, tumour differentiation, depth of invasion, bone invasion, muscle invasion, perineural invasion & extracapsular spread were evaluated & then correlated with lymphnode status. RESULTS Among all the parameters, variables like habit (tobacco use) (P = 0.045), tumour size (P = 0.003), perineural invasion (P = 0.000) emerged as independent prognosticators and significantly correlated to the lymph node status of the patients. CONCLUSIONS This analysis suggests that habit, tumour size, perineural invasion to be consistent, easy to assess and reliable independent prognosticators which are significantly correlated to the lymph node status. To conclude, it is of paramount importance to include the aforementioned prognosticators in histopathological reports for the prediction of clinical outcome and archiving of valued data for future analysis.

Abstract Background The most important prognostic factor in squamous cell carcinoma of the head and neck (HNSCC) is the presence or absence of clinically involved neck nodes. The presence of metastases in a lymph node is said to reduce the 5-years survival rate by about 50%. The appropriate diagnosis of the presence of metastatic node is very important for the management of HNSCC Aim To compare difTerent diagnostic modalities for assessment of the clinically non palpable lymph nodes in HNSCC including by meta-analysis: CT, MRI, US, USFNAC and PET/CT for the proper cervical lymph node staging. Methods Met-analysis study on patients with HNSCC of clinically non palpable lymph nodes (cN0). Results Analysis was divided in 6 groups .Each group contain analysis of one modality according to available studies per patient, per level and per lesion .US is fair test per patient and per lesion.CT is good test per patient and excellent test per lesion.MRI is poor test per patient and fair test per lesion.CT-MRl combined is fair per patient and excellent per level.PET/CT is good per patient, fair per lesion and excellent per level. USFNAC is excellent per lesion. Conclusion CT, CT-MRI combined, PET/CT and USFNAC proved to be excellent in detecting cN0.MRI was poor test in detecting cN0.US was a fair test in detecting cN0 if used alone.

ObjectiveLymph node metastasis is the most important factor influencing the prognosis of oral squamous cell carcinoma (OSCC) patients. However, there is no proper method for predicting lymph node metastasis. This study aimed to construct and validate a preoperative prediction model for lymph node metastasis and guide personalized neck management based on the gene expression profile and clinicopathological parameters of OSCC.MethodsBased on a previous study of related genes in OSCC, the mRNA expression of candidate genes was evaluated by real-time PCR in OSCC specimens. In this retrospective study, the gene expression profile and clinicopathological parameters of 112 OSCC patients were combined to construct the best prediction model for lymph node metastasis of OSCC. The model was validated with 95 OSCC samples in this study. Logistic regression analysis was used. The area under the curve (AUC) ultimately determined the diagnostic value of the prediction model.ResultsThe two genes CDKN2A + PLAU were closely related to lymph node metastasis of oral squamous cell carcinoma. The model with the combination of CDKN2A, PLAU, T stage and pathological grade was the best in predicting lymph node metastasis (AUC = 0.807, 95% CI: 0.713-0.881, P=0.0001). The prediction model had a specificity of 96% and sensitivity of 72.73% for stage T1 and T2 OSCC (AUC = 0.855, 95% CI: 0.697-0.949, P=0.0001).ConclusionsHigh expression of CDKN2A and PLAU was associated with lymph node metastasis in OSCC. The prediction model including CDKN2A, PLAU, T stage and pathological grade can be used as the best diagnostic model for lymph node metastasis in OSCC.

Abstract Background: Vasculogenic mimicry (VM) is the formation of an alternative circulatory system by aggressive tumor cells. The characteristics of VM and its underlying mechanism in oral squamous cell carcinoma (OSCC) remain unclear. This study aims to determine the relationship between VM channels in OSCC tissues and clinical outcomes and to investigate the biological role of SOX7 in VM in OSCC cells.Methods: CD31/PAS double staining was performed to evaluate VM status in OSCC tissue. The relationships between VM and clinicopathological variables, and VM and SOX7 levels were analyzed. The correlation between SOX7 levels and head and Neck cancer corhorts were investigated using in silico analysis.VM channel formation assay was performed to observe VM channels in the OSCC cell lines. To investigate the role of SOX7 in VM channel formation, SOX7 was transiently over-expressed in SCC-9 cells. VM-modulating genes were identified by Western blotting.Results: We confirmed the presence of VM channels in OSCC tissue and several cell lines and found a positive correlation between VM and lymph node metastasis and patient survival in OSCC (P = 0.003). In silico analysis from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) database showed that down-regulation of SOX7 expression was significantly correlated with head and neck squamous cell carcinoma (HNSCC) patient cohorts (P = 0.0187) and lymph node metastasis (P = 0.0017). We also found that the presence of VM channels in OSCC tissue was inversely associated with SOX7 expression (P = 0.020). We observed that overexpression of SOX7 impaired VM channel formation by reducing the expression of VE-cadherin, thereby inhibiting cell migration and invasion.Conclusion: These results suggest that SOX7 plays an important role in the regulation of VM channel formation and may inhibit OSCC metastasis.

A cross sectional study of 29 cases of oral squamous cell carcinoma with or without  cervical lymph node metastasis was done among Bangladeshi patients from January 2006 to December 2007. Majority of the study subjects (34.5%) belonged to the age group of 40-49 years. 58.6% of the study subjects were male, while remaining 41.4% of them were female. 51.7% of the lesions were located in the alveolar ridge where the other common sites were buccal mucosa (27.6%) and retro molar area (13.8%). Half of the study subjects (51.7%) were habituated to betel quid chewing followed by 37.9% and 10.3% were habituated to smoking and betel quid-smoking respectively. Grade I lesions was most prevalent (75.9%) in the study subjects.  Majority of cases presented with Stage IV lesions (55.2%). The sensitivity, specificity, positive predictive value, negative predictive value & accuracy of clinical palpation method for determining metastatic cervical lymph nodes were 93.33%, 64.29%, 73.68%, 90% and 79.3% respectively. Careful and repeated clinical palpation plays important role in evaluation of cervical lymph nodes though several modern techniques may help additionally in the management of oral cancer.DOI: http://dx.doi.org/10.3329/updcj.v1i2.13978 Update Dent.
