<p><strong>Background:</strong> More recently, established systemic inflammation-based prognostic scores have been explored extensively, such as neutrophil-lymphocyte ratio (NLR) and serum C-reactive protein. We postulated that NLR might be a readily available and inexpensive objective prognostic index that could be used in daily oncologic clinical practice and could help to stratify patients in clinical trials.<br /><strong>Materials and Methods:</strong> In total, there were 150 patients with oral squamous cell carcinoma (OSCC) treated at GSVM Medical College, Kanpur, between October 2012 and January 2015 whose clinical information and laboratory parameters were obtained. The NLR was determined by dividing the absolute neutrophil count by the absolute lymphocyte count, and the NLR data were then dichotomized and divided into two groups as NLR low and high. <strong>Conclusion:</strong> Our findings reported herein demonstrated that pretreatment NLR is a potential biomarker for predicting the overall survival in OSCC patients. Combined with other markers, NLR may be used in decision-making and the selection of treatment modality in patients with oral SCC.</p>

Introduction: Stathmin, one of the most important intracellular phosphoprotein that plays the vital role in the regulation of cell cycle and cell proliferation. It acts by disassembly of Microtubules (MT) that helps in the formation of mitotic spindle. It is overexpressed in various human cancers. Aim: To investigate the expression status of stathmin and its relation with clinicopathologic significance in Oral Squamous Cell Carcinoma (OSCC) and its association with age, sex, tobacco chewing, histomorphological features and pathological staging. Materials and Methods: A descriptive and observational study in cross-sectional design was conducted in a tertiary care centre of Kolkata, West Bengal, India, from January 2020 to March 2020 in the Department of Pathology of RG Kar Medical College and Hospital in collaboration with Department of Oto-Rhino-Laryngology of the same institute. Stathmin expression was assessed by immunohistochemistry (IHC) in 28 OSCC cases. The association between stathmin expression and clinicopathological parameters like age, sex, tobacco chewing, tumour site, histomorphological type, Tumor Nodes Metastases (TNM) stage and Worst Pattern Of Invasion (WPOI) were evaluated on the basis of Chi-square test and Fisher’s-exact test (software Statistical Package for the Social Sciences (SPSS) V 25.0). Results: Stathmin was overexpressed in 18 cases out of 28 cases of OSCC. In this study a positive association was observed between stathmin expression and age group, history of tobacco chewing, advanced T stage, advanced pTNM staging and WPOI of OSCC. Conclusion: The study suggests that overexpression of stathmin could contribute to cancer progression. There is a higher likelihood that stathmin may be used as a potential biomarker as well as therapeutic target for OSCC.

Background: Autophagy is a cellular process responsible for maintaining homeostasis; a dysregulation of this process is involved in the development and progression of neoplasms. Beclin-1 is one of the major proteins linked to autophagy. However, the data regarding the association between the role of Beclin-1 and the progression of Oral Squamous Cell Carcinoma (OSCC) are rather low. For this reason, the objective of this study is to evaluate, through immunohistochemical techniques, the prognostic role of the expression of Beclin-1 autophagy marker in patients with OSCC. Methods: This is a single-centre retrospective study that includes patients with OSCC admitted to the Maxillofacial Unit of “Magna Graecia” University between January 2019 and September 2020. All the samples obtained from surgery were treated with anti Beclin-1 antibodies and subjected to immunohistochemical methods. Results: A total of 26 samples were analysed and the following variables were evaluated for each: percentage of positive Beclin-1 expression by tumour cells, signal strength of tumour cells, and total score. The variables considered were first normalised according to the D’Agostino and Pearson test, then analysed using the Pearson linear correlation coefficient: a statistically significant correlation was found between the parameters infiltration-intensity (p = 0.0088), infiltration-percent (p = 0.0123), intensity-total score (p = 0.0060). Conclusions: The immunohistochemical evaluation of Beclin-1 revealed a statistically significant correlation between the intensity of the molecule’s expression and a greater degree of infiltration of the neoplasm. Beclin-1 can, therefore, be considered a valid prognostic index of disease.

The levels of different classes of extracellular RNAs (exRNAs) remain stable in bodily fluids. The detection of either enriched or depleted specific subsets of salivary microRNAs (miRNAs) has the potential to serve as a non-invasive approach for biomarker development. Thus, salivary miRNAs have emerged as a promising molecular tool for early diagnosis and screening of oral squamous cell carcinoma (OSCC). Total RNA was extracted from saliva supernatant of 33 OSCC patients and 12 controls (discovery set), and the differential expression of 8 cancer-related miRNAs was detected by TaqMan assay. Among the screened miRNAs, miR-30c-5p (p < 0.04) was significantly decreased in OSCC saliva. The same transcriptional behavior of miR30c-5p was observed in an additional validation set. miR-30c-5p showed a significant statistical difference between cases and controls with areas under the curve (AUC) of 0.82 (95% CI: 0.71–0.89). The sensitivity and the specificity of miR-30c-5p were 86% and 74%, respectively. The target identification analysis revealed enrichment of miR-30c-5p targets in p53 and Wnt signaling pathways in OSCC. Additionally, the miR-30c-5p targets had clinical significance related to overall survival. In conclusion, these findings show that downregulated miR-30c-5p has the potential to serve as a novel, non-invasive biomarker for early OSCC detection.
