The value of magnetic resonance imaging in predicting vesicovaginal fistula in cervical cancer with bladder invasion treated with definitive chemoradiotherapy.
Gynecol Oncol
January 2025
Department of Radiation Oncology, Asan Medical Center, University of Ulsan College of Medicine, Seoul, Republic of Korea. Electronic address:
Objectives: To assess the predictive value of magnetic resonance imaging for vesicovaginal fistula development in cervical cancer patients with bladder invasion treated with definitive chemoradiotherapy.
Methods: A retrospective review was conducted of the medical records of 43 cervical cancer patients with bladder invasion between 1999 and 2015. Bladder invasion was confirmed through magnetic resonance imaging (scores ≥3) or cystoscopic findings, with or without biopsy.
Learning curve and proficiency assessment for gynecological brachytherapy amongst radiation oncology trainees in India: Results from a prospective study.
Brachytherapy
January 2025
Department of Radiation Oncology and Medical Physics, Advanced Centre for Treatment Research and Education in Cancer, Tata Memorial Centre, Homi Bhabha National Institute, Navi Mumbai, India. Electronic address:
Purpose: The quality of cervical cancer intracavitary brachytherapy (ICBT) depends on the training and experience of the radiation oncologist (RO). The present study was performed to establish primary learning curve for ICBT.
Materials And Methods: Forty-three skill parameters were identified for performing ICBT and were included for Brachytherapy Proficiency Assessment and Scoring System (Brachy-PASS) questionnaire.
Intracavitary cisplatin-fibrin followed by irradiation improved tumor control compared to the single treatments in a mesothelioma rat model.

Department of Thoracic Surgery, University Hospital Zurich, Zurich, Switzerland.
Objective: To test the safety and efficacy of combination treatment for pleural mesothelioma (PM) with intracavitary cisplatin-fibrin (cis-fib) plus hemithoracic irradiation (IR) applied after lung-sparing surgery in an orthotopic immunocompetent rat model.
Methods: We randomized male F344 rats into 5 groups: cis-fib (n = 9), 10 Gy IR (n = 6), 20 Gy IR (n = 9), cis-fib+10 Gy IR (n = 6), and cis-fib+20 Gy IR (n = 9). Subpleural tumor implantation was performed on day 0 with 1 million syngeneic rat mesothelioma cells (IL45-luciferase).
Preclinical Experience Using 4D Intracardiac Echocardiography to Guide Cardiac Electrophysiology Procedures.
J Cardiovasc Electrophysiol
December 2024
Division of Cardiovascular Medicine, Cardiac Electrophysiology Section, Hospital of the University of Pennsylvania, Philadelphia, Pennsylvania, USA.
Introduction: Intracardiac echocardiography (ICE) is an essential imaging modality for electrophysiology procedures, allowing intraprocedural monitoring, real-time catheter manipulation guidance, and visualization of complex anatomic structures. Four-dimentional (4D) ICE is the next stage in the evolution of the technology, permitting 360° rotation of the imaging plane, simultaneous multiplanar imaging, and volumetric acquisition, similar to transesophageal echocardiography (TEE). In this study, we report our experience with a novel 4D ICE catheter (NuVision, Biosense Webster) in structural electrophysiology procedures and difficult ventricular ablations in a swine preclinical model.

Echocardiography
January 2025
Echocardiography Department, National Institute of Cardiology Ignacio Chávez, México City, México.
We present a case of a 72-year-old female patient with dyspnea and lipothymia. Echocardiography demonstrates an intracavitary cystic mass that fills almost all left atria causing supravalvular obstruction. The magnetic resonance image revealed a 53 × 47 × 48 mm heterogeneous mass with regular edges, tissue characterization suggested myxoma.
