Sarcomas are rare tumors of mesenchymal origin and comprise only around 1% of adult cancers. The abundance of sarcoma histiotypes, with distinct imaging characteristics, biology, clinical behavior and treatment strategy, result in a complex disease presentation, requiring management by multidisciplinary specialized sarcoma centers. Oncologic and musculoskeletal radiology guidelines provide minimal guidance and only fragmentary information on the indications of F-FDG PET/CT in sarcoma. Therefore, knowledge of various phenotypes with preference for bone and lymph node metastases or higher incidence of local and distant recurrence is essential to select the appropriate diagnostic imaging tests and its interpretation. Benign and malignant soft tissue and bone tumors often share common radiographic and metabolic imaging characteristics. In addition, metastases of various histiotypes might exhibit a spectrum of atypical imaging appearances. Therefore, imaging specialists need to be aware of these variants and associated pitfalls of sarcoma imaging.

Longitudinal assessment of diffusion-weighted imaging during magnetic resonance-guided radiotherapy in head and neck cancer.
Radiat Oncol
January 2025
German Cancer Consortium (DKTK), partner site Tübingen, and German Cancer Research Center (DKFZ), Heidelberg, Germany.
Background: For radiotherapy of head and neck cancer (HNC) magnetic resonance imaging (MRI) plays a pivotal role due to its high soft tissue contrast. Moreover, it offers the potential to acquire functional information through diffusion weighted imaging (DWI) with the potential to personalize treatment. The aim of this study was to acquire repetitive DWI during the course of online adaptive radiotherapy on an 1.

BMC Palliat Care
January 2025
Palliative Care Unit, National Cancer Institute, Rio de Janeiro, Brazil.
Objective: To compare the sociodemographic and clinical profiles of patients with advanced cancer admitted to a tertiary palliative care unit before and during the COVID-19 pandemic.
Methods: This is an analysis of data from patients receiving care before (10/21/2019 to 03/16/2020) and during (09/23/2020 to 08/26/2021) the COVID-19 pandemic. Sociodemographic and clinical data were evaluated.
An evaluation of surgical excision versus steroid injection for the management of ganglion cysts.
Sci Rep
January 2025
Department of General Surgery, Saveetha Medical College and Hospital, Saveetha Institute of Medical and Technical Sciences (SIMATS), Saveetha University, Chennai, India.
Ganglion cysts are benign soft tissue tumors that commonly occur in the joints, especially the wrist. Surgical excision and steroid injection are the two main treatment options; however, their efficacy remains unclear. This prospective interventional control trial included 54 patients with ganglion cysts treated between March 2023 and March 2024 at Saveetha Medical College Hospital, Chennai.

Department of Plastic and Reconstructive Surgery, Dongtan Sacred Heart Hospital, Hallym University College of Medicine, Hwaseong, Republic of Korea.
Background: Unicortical plate fixation offers several theoretical advantages in the treatment of metacarpal shaft fractures compared to bicortical fixation. This approach avoids the potential hazard of excessive drilling into the volar cortex, thus minimizing damage to surrounding soft tissues and helping prevent complications related to improperly sized screws. These benefits prompted our team to conduct a preliminary clinical study to investigate the effectiveness and safety of this approach.

Background: Inflammatory myofibroblastic tumors (IMTs), rare soft tissue neoplasms, are characterized by a blend of myofibroblastic proliferation and inflammatory features. While generally characterized by slow growth, IMTs can exhibit locally aggressive behavior, and in rare instances, metastasize to distant sites. This study elucidated the clinical characteristics, molecular profile, and tumor microenvironment of thoracic IMTs.
