Malignant peripheral nerve sheath tumour (MPNST) of the cervix: differential diagnosis and a favourable oncological outcome with multimodality treatment.
BMJ Case Rep
January 2025
Obstetrics and Gynecology, All India Institute of Medical Sciences, New Delhi, Delhi, India.
Malignant peripheral nerve sheath tumours (MPNSTs) are aggressive sarcomas that occur rarely in the cervix. Considering the varied clinical features and the absence of a pathognomonic immunohistochemical marker, it is always challenging to diagnose these tumours. Treatment has not been standardised as yet, but a combination of surgery, radiotherapy and chemotherapy is used to treat MPNSTs of the cervix.

Background: B7-H3 or CD276 is notably overexpressed in various malignant tumor cells in humans, with extremely high expression rates. The development of a radiotracer that targets B7-H3 may provide a universal tumor-specific imaging agent and allow the noninvasive assessment of the whole-body distribution of B7-H3-expressing lesions.
Methods: We enhanced and optimized the structure of an affibody (ABY) that targets B7-H3 to create the radiolabeled radiotracer [68Ga]Ga-B7H3-BCH, and then, we conducted both foundational experiments and clinical translational studies.
Physical Activity and Quality of Life After Distal Femur Tumor Resection and Limb Salvage.
J Funct Morphol Kinesiol
December 2024
First Department of Orthopedic Surgery, School of Medicine, National and Kapodistrian University of Athens, Attikon University General Hospital, 12462 Athens, Greece.
: Distal femur tumor resection with limb salvage is a demanding procedure that offers hope for patients by preserving the limb rather than opting for amputation. While limb salvage can improve both physical function and psychological well-being, there's limited knowledge on how active patients remain afterward and how their Quality of Life (QoL) is affected, especially regarding physical activities and sports. This study investigates the quality of life of the patients through the development of motor activity, focusing on both physical and sporting activity of the above-mentioned individuals and their physical abilities to participate in activities of daily and sporting life after surgery.

J Magn Reson Imaging
January 2025
Department of Medical Imaging, University of Toronto, Toronto, Ontario, Canada.
Background: Differentiation of benign myxomas and malignant myxoid sarcomas can be difficult with an overlapping spectrum of morphologic MR findings.
Purpose: To assess the diagnostic utility of MRI radiomics in the differentiation of musculoskeletal myxomas and myxoid sarcomas.
Study Type: Retrospective.
Design, Synthesis, and SAR of Covalent KIT and PDGFRA Inhibitors─Exploring Their Potential in Targeting GIST.

Department of Chemistry and Chemical Biology, TU Dortmund University and Drug Discovery Hub Dortmund (DDHD), Zentrum für Integrierte Wirkstoffforschung (ZIW), Otto-Hahn-Strasse 4a, Dortmund 44227, Germany.
Gastrointestinal stromal tumors (GIST), driven by KIT and PDGFRA mutations, are the most common mesenchymal tumors of the gastrointestinal tract. Although tyrosine kinase inhibitors (TKIs) have advanced treatment, resistance mutations and off-target toxicity limit their efficacy. This study develops covalent TKIs targeting drug-resistant GIST through structure-based design, synthesis, and biological evaluation.
