Purpose: No consensus exists regarding the most appropriate staging system to predict overall survival (OS) for hepatocellular carcinoma (HCC) in surgical candidates. Thus, we aimed to determine the prognostic ability of eight different staging systems in a European cohort of patients undergoing liver resection for HCC.
Methods: Patients resected for HCC between 2010 and 2019 at our institution were analyzed with Kaplan-Meier and Cox regression analyses. Likelihood ratio (LR) χ (homogeneity), linear trend (LT) χ (discriminatory ability), and Akaike Information Criterion (AIC, explanatory ability) were used to determine the staging system with the best overall prognostic performance.
Results: Liver resection for HCC was performed in 160 patients. Median OS was 39 months (95% confidence interval (CI): 32-46 months) and median RFS was 26 months (95% CI: 16-34 months). All staging systems (BCLC, HKLC, Okuda, CLIP, ITA.LI.CA staging and score, MESH, and GRETCH) showed significant discriminatory ability regarding OS, with ITA.LI.CA score (LR χ 30.08, LT χ 13.90, AIC 455.27) and CLIP (LR χ 28.65, LT χ 18.95, AIC 460.07) being the best performing staging systems.
Conclusions: ITA.LI.CA and CLIP are the most suitable staging system to predict OS in European HCC patients scheduled for curative-intent surgery.

This study investigates the relationship between SARS-CoV-2 RT-PCR cycle threshold (Ct) values and key COVID-19 transmission and outcome metrics across five years of the pandemic in Jalisco, Mexico. Utilizing a comprehensive time-series analysis, we evaluated weekly median Ct values as proxies for viral load and their temporal associations with positivity rates, reproduction numbers (Rt), hospitalizations, and mortality. Cross-correlation and lagged regression analyses revealed significant lead-lag relationships, with declining Ct values consistently preceding surges in positivity rates and hospitalizations, particularly during the early phases of the pandemic.

This in vivo study introduces a newly developed spirooxindole derivative that is deemed safe and effective as a potential targeted therapy for various cancers. Extensive in vivo investigations, including histopathology, immunohistochemistry, and molecular biology, validated its potential for further preclinical and clinical exploration, necessitating comprehensive examinations of its bioavailability, pharmacodynamics, and pharmacokinetics. Additionally, this study involves the development of a commercially viable proniosomal drug delivery system for the compound, facilitating controlled drug release.

Lung cancer remains a major global health problem because of its high cancer-related mortality rate despite advances in therapeutic approaches. Non-small cell lung cancer (NSCLC), a major subtype of lung cancer, is more amenable to surgical intervention in its early stages. However, the prognosis for advanced NSCLC remains poor, owing to limited treatment options.
