The Frontline and Relapsed Rhabdomyosarcoma (FaR-RMS) clinical trial is an overarching, multinational study for children and adults with rhabdomyosarcoma (RMS). The trial, developed by the European Soft Tissue Sarcoma Study Group (EpSSG), incorporates multiple different research questions within a multistage design with a focus on (i) novel regimens for poor prognostic subgroups, (ii) optimal duration of maintenance chemotherapy, and (iii) optimal use of radiotherapy for local control and widespread metastatic disease. Additional sub-studies focusing on biological risk stratification, use of imaging modalities, including [F]FDG PET-CT and diffusion-weighted MRI imaging (DWI) as prognostic markers, and impact of therapy on quality of life are described.

Background: Patients with intermediate and high-risk oropharyngeal cancer (OPC) have poorer response to standard treatment and poorer overall survival compared to low-risk OPC. CompARE is designed to test alternative approaches to intensified treatment for these patients to improve survival.

Methods: CompARE is a pragmatic phase III, open-label, multicenter randomised controlled trial with an adaptive multi-arm, multi-stage design and an integrated QuinteT Recruitment Intervention.

Article Synopsis
  • Late-phase platform protocols, such as basket and master protocols, are more efficient than traditional two-arm trials but are underutilized; this study shares operational recommendations from successful implementations.* -
  • A meeting of UK clinical trial experts was held to discuss the practical challenges and operational aspects specific to running late-phase platform trials, leading to a set of guidance for trialists.* -
  • The recommendations cover all stages of a platform trial, emphasizing key areas like protocol development, funding, staffing, data management, and effective communication with participants and stakeholders.*

Background: Sarcopenia is an important cause of morbidity and mortality in older adults, with immunosenescence and inflammation being possible underlying mechanisms. We investigated the relationship between latent cytomegalovirus (CMV) infection, Interleukin 6 (IL-6) levels, muscle size and strength in a group of healthy older community-dwelling people.

Methods: Participants were healthy volunteers from the Lothian Birth Cohort 1936 study.

Cytomegalovirus infection has been implicated in cognitive impairment in studies using brief clinical assessments though findings are inconsistent. The association between cytomegalovirus infection, measured as serostatus or a semiquantitative assessment of antibody level, and cognitive abilities in a sample of older adults was examined. Cytomegalovirus status was assessed at a mean age of 70 years in 1061 participants of the Lothian Birth Cohort 1936.

Aging is accompanied by the development of low-grade systemic inflammation, termed 'inflammaging', characterized by raised serum C-reactive protein (CRP) and pro-inflammatory cytokines. Importantly, inflammaging is implicated in the pathogenesis of several of the major age-related diseases including cardiovascular disease, type 2 diabetes, and dementia and is associated with increased mortality. The incidence of infection with the persistent herpes virus cytomegalovirus (CMV) also increases with age.
