Objective: Recent studies have shown that the presence of systemic inflammation and platelet status correlate with poor survival in various cancers. The aim of this study was to evaluate the prognostic value of the preoperative platelet-lymphocyte ratio (PLR) and the neutrophil-lymphocyte ratio (NLR) in patients with oral squamous cell carcinoma (OSCC) undergoing surgery.
Methods: In this study, 306 patients with OSCC who had surgery were enrolled. The optimal cutoff value of PLR and NLR was determined by receiver operating characteristic (ROC) curve analysis. The prognostic significance of both markers was determined by uni- and multivariate analysis.
Results: The results showed that high NLR and PLR were classified using a cutoff value of 2.7 and 135, respectively, based on ROC curve analysis. Only PLR was associated with decreased disease-free survival [hazard ratio (HR) = 2.237; 95% confidence interval (CI): 1.401-3.571; p = 0.001] and overall survival [HR = 2.022; 95% CI: 1.266-3.228; p = 0.003] by both uni- and multivariate analysis.
Conclusion: The preoperative PLR is superior to NLR as an independent indicator in predicting disease-free survival and overall survival in patients who undergo oral cancer resection for OSCC.

Objectives: Albumin-globulin ratio (AGR), prognostic nutritional index (PNI), and platelet-to-lymphocyte ratio (PLR) have been validated as prognostic factors for gastric cancer (GC). However, significant gender differences exist in albumin levels and inflammatory cell counts, and further research is required to understand how these differences influence GC prognosis. This study aims to investigate the prognostic impact of nutritional and inflammatory indicators on GC patients undergoing radical surgery, as well as the influence of gender on these indicators' prognostic value.

Background: This specific study evaluates the accuracy of two ratios, Neutrophil-to-Lymphocyte (N/L) and Platelet-to-Lymphocyte (P/L), as inflammatory markers on differentiating simple and complicated appendicitis preoperatively.
Methods: The medical records of 341 children, up to 16 years old, with suspected acute appendicitis (AA) who underwent appendectomy, laparoscopic or open, between January 2020 and December 2022, in our department, were retrospectively reviewed. Routine blood exams and the demographic details were obtained.

Purpose: Postoperative fever (POF)/urinary tract infection (UTI) is one of the most unpleasant and undesirable conditions for surgeons after retrograde intrarenal surgery (RIRS). RIRS is not recommended for any patient with a positive urine culture to avoid POF and UTI, but some patients may develop postoperative UTI even if the urine culture is sterile. This study investigated the predictive factors of fever and UTIs after RIRS.

Background: There is a paucity of literature regarding the effect of anesthetic techniques on anti-tumor immunity, especially in Oral cavity Malignancies. We designed a study to evaluate the effect of 3 anesthetic techniques - Opioid, Lignocaine infusion and Dexmeditomedine infusion-based on anti-tumor immunity, using TGF-β, T-helper cell profile and inflammatory markers such as IL-6 and IL-10.
Methods: A pilot prospective randomized trial was conducted in 90 patients undergoing surgery for Oral cavity malignancy under general anesthesia in a tertiary specialty cancer hospital.
