Preoperative PLR is directly associated with nodal involvement status of OSCC. Preoperative PLR is superior to NLR for predicting LNM in OSCC.

Context:Biochemical changes occur in biological fluids and tissues of different types of malignancies. Tumor markers in serum, tissue, and other body fluids during neoplastic process are of clinical value in the management of patients with cancers. Serum alkaline phosphatase (ALP) activity is potentially a useful indicator for detection of malignancies, but its status in oral squamous cell carcinoma (OSCC) is less explored.Aims:The aim of this study is to evaluate the serum level of ALP in OSCC patients and assess its relation with the clinicopathological features.Settings and Design:A total of 175 participants (145 OSCC patients and 30 healthy controls) were included in the study. One hundred and forty-five patients with OSCC who underwent treatment at our institution were included to obtain the clinicopathological data.Materials and Methods:Fasting blood ALP activity was evaluated using ALP assessment kit and biochemistry analyzer.Statistical Analysis Used:The data were analyzed by SPSS-21 software (SPSS Statistics for Windows, Version 21.0, Armonk, NY, USA), using t-test, Mann–Whitney U, and Kruskal–Wallis tests.Results:Raised ALP was seen in 24% of OSCC patients. The mean ALP in OSCC was significantly higher than the control. ALP level in patients with advanced stage was significantly higher than with early stage. The serum ALP level in OSCC patients with bone involvement (BI) by local extension of tumor was significantly higher than without BI.Conclusion:ALP showed statistically significant differences in relation to tumor stages and BI. Hence, ALP could be useful in advanced stage disease for expressing the endurance of patient and tumor expansion. Elevated ALP in OSCC patients may indicate BI.

Background:Secretor status may possibly be one of the factors in the etiopathogenesis of oral precancerous lesions and subsequently cancer. Studies have shown the relationship between the pathogenesis of disease and secretor status. They have made known that secretor status is a possible factor influencing disease status. Studies have revealed the association between blood groups and specific diseases.Aims:To assess any association of ABO blood grouping with oral potentially malignant disorders (OPMDs) and to examine whether there is any difference in the saliva secretor status in the patients with OPMDs and healthy controls.Materials and Methods:The study consisted of 90 subjects, with 45 patients assigned to two groups (a) Patients with potentially malignant disorders and (b) healthy controls. ABO blood grouping was done and 1 ml of unstimulated saliva was collected in a sterile test tube. The Wiener agglutination test was performed to analyze the secretor status in both the groups. Chi-square test and odd ratio were used to assess the relationship between ABO blood group and OPMDs. Chi-square test was performed to assess the relationship between secretor status and OPMDs. Probability level was fixed at <0.05.Results:The results demonstrated a statistically significant relation between OPMDs and secretor status (P = 0.00). Eighty-seven percent of patients with OPMDs were nonsecretors, while in the control group sixteen percent of them were nonsecretors. There was no statistically significant relationship between ABO blood groups and OPMDs (P > 0.05).Conclusions:The study confirms the inability to secrete blood group antigens in the saliva of patients with OPMDs which could be regarded as a host risk factor. Results could not propose a relationship between ABO blood group and OPMDs.

Introduction: Percutaneous thermal ablation is widely adopted as a curative treatment approach for unresectable liver neoplasms. Accurate immediate assessment of therapeutic response post-ablation is critical to achieve favourable outcomes. The conventional technique of side-by-side comparison of pre- and post-ablation scans is challenging and hence there is a need for improved methods, which will accurately evaluate the immediate post-therapeutic response. Objectives and Significance: This review summarizes the findings of studies investigating the feasibility and efficacy of the fusion imaging systems in the immediate post-operative assessment of the therapeutic response to thermal ablation in liver neoplasms. The findings could potentially empower the clinicians with updated knowledge of the state-of-the-art in the assessment of treatment response for unresectable liver neoplasms. Methods and Analysis: A rapid review will be performed on publicly available major electronic databases to identify articles reporting the feasibility and efficacy of the fusion imaging systems in the immediate assessment of the therapeutic response to thermal ablation in liver neoplasms. The risk of bias and quality of articles will be assessed using the Cochrane risk of bias tool 2.0 and Newcastle Ottawa tool. Ethics and Dissemination: Being a review, we do not anticipate the need for any approval from the Institutional Review Board. The outcomes of this study will be published in a peer-reviewed journal. Highlights Evaluation of the therapeutic response in liver neoplasms immediately post-ablation is critical to achieve favourable patient outcomes. We will examine the feasibility and technical efficacy of different fusion imaging systems in assessing the immediate treatment response post-ablation. The findings are expected to guide the clinicians with updated knowledge on the state-of-the-art when assessing the immediate treatment response for unresectable liver neoplasms.
