Article Abstract
Background: Pediatric acute lymphoblastic leukemia (ALL) arises from B- or T-lineage lymphoid progenitors is the most common form of childhood cancer.
Aim: This study aimed to develop a prognostic signature for overall survival (OS) in pediatric ALL patients.
Methods: Pediatric ALL driver genes were used for LASSO-Cox regression to construct a prognostic model in a training cohort (GDC TARGET-ALL-P2, n = 103). The model's performance was assessed and validated in an independent cohort (GDC MP2PRT-ALL, n = 132).
Results: Thirteen genes out of 367 potential driver genes associated with ALL were selected for model construction. In the training cohort, the model has AUC values of 0.73, 0.89, and 0.832 at 365, 1,095 and 1,825 days, respectively. High-risk patients had significantly worse OS (hazard Ratio, HR = 10.87, 95% CI: 5.93-19.95, P < 0.001). In the invalidation cohort, it has an AUC value of 0.82 at 365 days and an HR of 3.048 (95% CI: 1.780-5.219, P < 0.001).
Conclusion: This study identifies a 13-gene signature as a promising tool for risk stratification in pediatric ALL.

Background: Previous studies indicated that over-dissection of lymph nodes might impair the efficacy of immunotherapy. This study aims to explore the prognostic value of ypN + status and the impact of lymph node dissection (LND) on survival after neoadjuvant immunochemotherapy (NICT) for esophageal squamous cell cancer (ESCC).
Methods: This double-center retrospective study enrolled 206 consecutive ESCC patients who underwent NICT followed by esophagectomy between 2018 and 2024.

Whole blood (WB) transcriptomics offers a minimal-invasive method to assess patients' immune system. This study aimed to identify transcriptional patterns in WB associated with clinical outcomes in patients treated with immune checkpoint inhibitors (ICIs). We performed RNA-sequencing on pre-treatment WB samples from 145 patients with advanced cancer.

Introduction: Goals of left ventricular assist device (LVAD) therapy includes low rates of right ventricular failure (RVF) and favorable survival outcomes. However, conventional metrics often fail to capture its physiologic complexity. We evaluated the prognostic utility of the Active Cardiac Index (ActCI) and Passive Cardiac Index (PasCI)-which reflect cardiac output driven by active RV contractility and passive venous return, respectively.

Background: Acute upper gastrointestinal bleeding (AUGIB) is a critical medical emergency and is a common cause of illness and death in individuals with liver cirrhosis.
Objective: The point of this study was to check how well the albumin-to-bilirubin ratio (ALBI) and model for end-stage liver disease (MELD) scores could predict how these patients would do in the future.
Methods: The Imam Khomeini Hospital gastroenterology department conducted a retrospective examination.
