Objectives: We investigated the prognostic value of pre-treatment hematological parameters in patients with p16-positive oropharyngeal squamous-cell carcinoma (OPSCC).
Material And Methods: Neutrophil count, lymphocyte count, neutrophil-to-lymphocyte ratio (NLR), and hemoglobin concentration measurement (Hb), were collected on day one of treatment. Endpoints were overall survival (OS) and progression-free survival (PFS). All patients were planned to receive concurrent chemoradiation. Staging were reviewed according to the recent AJCC 8th edition.
Results: We included 167 patients in this study. In multivariate analyses, a smoking history > 30 packyears was associated with decreased OS (p = 0.009; HR, 3.4827) and PFS (p = 0.042; HR, 2.421); Hb < 12g/dL was associated with impaired OS (p = 0.007; HR, 6.527) and PFS (p = 0.014; HR, 4.092); an NLR > 5 before treatment was associated with decreased OS (p = 0.042; HR, 2.945). Hemoglobin concentration and the NLR were not correlated (p = 0.577), nor anemia and an NLR > 5 (p = 0.167). Patients with an NLR > 5 had a significantly higher rate of disease recurrence (30.8% vs. 8.4%, p = 0.0299, RR = 3.922, 95% CI 1.351-11.386).
Discussion: We found hemoglobin level and the NLR to be independent prognostic factors in p16-positive OPSCC patients. This approach is to be considered for further clinical investigations, and its significance in treatment decision-making should be further explored.

Prognostic scores for predicting overall survival in patients with metastatic renal and urothelial cancer undergoing immunotherapy - which one to use?
World J Urol
January 2025
Department of Urology, University of Kiel (UKSH), Arnold-Heller-Strasse 1-3, 24105, Kiel, Germany.
Purpose: Evaluation of the prognostic significance of four different scoring systems in a real-world cohort of patients with metastatic urothelial carcinoma (mUC) or renal cell carcinoma (mRCC) undergoing immunotherapy (IO).
Methods: For 120 patients with mUC (n = 67) and mRCC (n = 53) who received IO between July 2016 and December 2020 at the tertiary Urological University Medical Centre Mannheim, the following scores were recorded at pre-treatment baseline: modified Glasgow prognostic score (mGPS), systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-eosinophil ratio (NER). Overall survival (time between the beginning of IO until the patients' death or last contact) was determined for every patient.
THE IMPACT OF NEUTROPHIL-TO-LYMPHOCYTE RATIO ON SHORT- AND LONG-TERM PROGNOSIS FOLLOWING ELECTIVE INFRARENAL EVAR.
Ann Vasc Surg
January 2025
Hospital de Santa Marta, Unidade Local de Saúde São José, Lisboa, Portugal.
Objective: Neutrophil-to-lymphocyte ratio (NLR) is a readily available parameter, associated with long-term outcomes in cardiovascular conditions. This study aims to analyze the predictors of NLR and its impact on prognosis and disease-specific outcomes following EVAR.
Methods: Single-center retrospective cohort study.
Relationship between muscular mass, inflammatory status, tumor metabolic activity and oral intake in head and neck cancer at the outset of management.

Background And Aims: Patients with head and neck cancer (HNC) are often malnourished with a low muscular mass at the outset of management. This is thought to be mainly due to poor nutritional intake. The aim of this study was to assess the correlation between tumor metabolic activity, inflammatory status and body composition in HNC patients.

Hemolysis, elevated liver enzymes, low platelet count (HELLP) syndrome is a severe complication of preeclampsia (PE), with a higher incidence rate in people living at high altitudes, such as Tibet area. Maternal HELLP syndrome is associated with an elevated neonatal mortality rate. The purpose of this study was to investigate the predicting factors for neonatal outcomes with maternal HELLP syndrome.

Objective: T cell-mediated rejection (TCMR) is a major concern following liver transplantation (LT), and identifying its predictors could help improve post-transplant prognosis. This study aimed to develop a model to predict the risk of TCMR in children and adults after LT.
Method: Pre-transplant demographic characteristics, intraoperative parameters, and especially early post-transplant laboratory data for 1,221 LT recipients (1,096 adults and 125 children) were obtained from Hospital, University, between 1 January 2015, and 1 January 2022.
