Essential Updates 2024–2025: Surgical Strategy for Esophageal Cancer Toward a New Paradigm in the Era of Immunotherapy and Personalization

Annals of Gastroenterological Surgery, EarlyView.
This review summarizes key advances from 2024 to 2025 that are reshaping esophageal cancer surgery toward a strategy‐oriented, personalized paradigm through the integration of immunotherapy, population aging, and intelligent technologies. Adjuvant nivolumab after neoadjuvant chemoradiotherapy remains the only perioperative approach with durable benefit,

Malignant Lymphoma in the Psoas Major Muscle [PDF]

Case Reports in Hematology, 2017
An 84-year-old Japanese man taking warfarin to prevent cerebral infarction secondary to atrial fibrillation was admitted to our hospital for evaluation of a painless right back mass. Magnetic resonance imaging (MRI) showed an oval-shaped mass in the right psoas major muscle. The mass showed high intensity on T1-, T2-, and diffusion-weighted imaging and

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

The Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Iliac Attachment of the Psoas Major Muscle: Anatomical Study of a Novel Muscle Attachment

Clinical Anatomy, EarlyView.
ABSTRACT The iliopsoas muscle is important functionally and is often encountered during various surgical procedures. During routine cadaveric dissection, a previously undescribed muscular structure was located deep to the iliacus muscle and coursed inferomedially to merge with the posterior aspect of the psoas major, running over the iliopectineal ...

Potential of whole-body dual-energy X-ray absorptiometry to predict muscle size of psoas major, gluteus maximus and back muscles

BMC Musculoskeletal Disorders, 2023
Background Measurement of trunk muscle cross-sectional area (CSA) using axial magnetic resonance imaging (MRI) is considered clinically meaningful for understanding several spinal pathologies, such as low back pain and spinal sagittal imbalance. However,

Solitary neurofibroma of the psoas muscle

Current Medicine Research and Practice, 2022
Neurofibroma is a benign peripheral nerve sheath tumour usually present on superficial tissues of the head and trunk. Retroperitoneal location is extremely rare for neurofibroma and comprises only 1% of all retroperitoneal tumours.

Utilisation of Objective and Subjective Image Quality Metrics to Guide Optimal Contrast Volumes for Abdominal CT

Journal of Medical Radiation Sciences, EarlyView.
Determining the appropriate volume of iodinated contrast media (ICM) for portal venous phase abdominal CT is challenging. Objective image quality assessment demonstrates weight‐based volume dosing reduces the dependence of enhancement on patient size, compared to fixed volume.

Psoas muscle index is not representative of skeletal muscle index for evaluating cancer sarcopenia

Journal of Cachexia, Sarcopenia and Muscle, 2023
Background A common method for diagnosing sarcopenia involves estimating the muscle mass by computed tomography (CT) via measurements of the cross‐sectional muscle area (CSMA) of all muscles at the third lumbar vertebra (L3) level.
