Article Abstract
Objective: Dysregulation of long noncoding RNA is associated with a variety of cancers and LncRNA has anticancer or carcinogenic activities. PVT1, as a long noncoding RNA, plays an important role in the development of cancer.
Methods: We use R to download and analyze the data in TCGA database. ROC curve is generated to evaluate the significance of PVT1 expression for the diagnosis of prostate cancer. Chi-square test is used to test correlation between PVT1 expression and clinical pathological features. Survival curve and univariate and multivariate cox regression analysis is performed to compare differences in the effect on the survival rate between PVT1 high expression and low expression.
Results: The expression of PTV1 in tumor tissues was significantly higher than that in normal tissues(P<2.2e-16). The difference of PTV1 expression was observed according to vital status (P = 0.0051) and Gleason score (P = 0.0012). The expression of PTV1 is significantly associated with T classification (P < 0.0001), N classification (P = 0.0499), PSA (P = 0.0001), Gleason Score (P < 0.0001), targeted molecular therapy (P = 0.0264) and vital status(P = 0.0036). The area under the ROC curve (AUC) was 0.860, which revealed PTV1 expression has excellent diagnostic value in prostate cancer. Patients with high PVT1 expression had a worse prognosis.
Conclusions: PVT1 expression may be a biomarker for the diagnosis and prognosis of prostate cancer.

Broad-Spectrum Antibiotic Use at the End of Life in Patients With Advanced Cancer.
JAMA Netw Open
September 2025
Department of Internal Medicine, Seoul National University Hospital, Seoul National University College of Medicine, Seoul, South Korea.
Importance: Patients with advanced cancer frequently receive broad-spectrum antibiotics, but changing use patterns across the end-of-life trajectory remain poorly understood.
Objective: To describe the patterns of broad-spectrum antibiotic use across defined end-of-life intervals in patients with advanced cancer.
Design, Setting, And Participants: This nationwide, population-based, retrospective cohort study used data from the South Korean National Health Insurance Service database to examine broad-spectrum antibiotic use among patients with advanced cancer who died between July 1, 2002, and December 31, 2021.
The dynamic nature of frailty in metastatic spine disease patients.

Department of Neurosurgery, University of Michigan, Ann Arbor, MI, USA.
Purpose: Frailty measures are critical for predicting outcomes in metastatic spine disease (MSD) patients. This study aimed to evaluate frailty measures throughout the disease process.
Methods: This retrospective analysis measured frailty in MSD patients at multiple time points using a modified Metastatic Spinal Tumor Frailty Index (MSTFI).
Impact of sociodemographic and socioeconomic factors on functional and health-related quality of life outcomes 24 months after radical prostatectomy.

Department of Urology, University Hospital Tübingen, Eberhard Karls University, Hoppe-Seyler Str. 3, 72076, Tübingen, Germany.
Introduction And Objectives: High socioeconomic status (SES) is associated with improved oncological outcomes across various cancer types, including prostate cancer. However, limited evidence exists regarding the impact of SES and lifestyle factors on patient-reported outcomes (PROs), including quality of life (QoL), health status (HS), and functional recovery following radical prostatectomy (RP).
Materials And Methods: We conducted a retrospective single-center analysis of 327 patients undergoing RP (177 open, 150 robotic-assisted) assessing pre- and postoperative functional outcomes (QoL, HS, erectile function, continence).

Introduction: Brachytherapy has been used for the multimodal treatment of pediatric bladder-prostate rhabdomyosarcoma in the last two decades. The aim of this systematic review is to gather the current evidence about this innovative technique with a special focus on long-term outcomes.
Methods: According to PRISMA criteria, PubMed, Scopus, and Web of Science were searched for papers published between 2000 and 2022.

Objective: CXCR4 and integrin αβ play important roles in tumor biology and are highly expressed in multiple types of tumors. This study aimed to synthesize, preclinically evaluate, and clinically validate a novel dual-targeted PET imaging probe Ga-pentixafor-c(RGDfK) for its potential in imaging tumors.
Methods: The effects of Ga-pentixafor-c(RGDfK) on cell viability, targeting specificity, and affinity were assessed in the U87MG cells.
