Recent advances in radiopharmaceutical therapy (RPT) and radioembolization (RE) will make these forms of therapy more prevalent in radiation oncology and nuclear medicine clinics. This article guides medical physicists in radiation oncology by summarizing current RPT and RE techniques, processes, safety, quality assurance, equipment, etc. The summarized guidance, which addresses technical considerations, may be applied broadly to develop a clinical RPT/RE program that offers multiple types of such therapies.

Resistance to chimaeric antigen receptor (CAR) T cell therapy develops through multiple mechanisms, most notably antigen loss and tumour-induced immune suppression. It has been suggested that T cells expressing multiple CARs may overcome the resistance of tumours and that T cells expressing receptors that switch inhibitory immune-checkpoint signals into costimulatory signals may enhance the activity of the T cells in the tumour microenvironment. However, engineering multiple features into a single T cell product is difficult because of the transgene-packaging constraints of current gene-delivery vectors.

Background: Gliomas are a major cause of cancer-related death among children, adolescents, and young adults (age 0-40 years). Primary mismatch repair deficiency (MMRD) is a pan-cancer mechanism with unique biology and therapeutic opportunities. We aimed to determine the extent and impact of primary MMRD in gliomas among children, adolescents, and young adults.

Article Synopsis
  • Understanding the connectivity between endangered marine populations is crucial for their management and conservation, as factors like ocean conditions and species-specific traits influence how these populations interact.
  • In the study, researchers examined five species of Rockfish in Puget Sound using extensive genetic data, revealing distinct patterns of genetic differentiation influenced by both external and internal factors.
  • The findings highlighted that most Rockfish species displayed unique population structures, emphasizing the need for tailored management strategies instead of relying on generalized assumptions, like federal management boundaries, to effectively support recovery efforts.

is a partially migratory salmonid species, and many migratory populations (known as steelhead) have declined in recent decades in the western United States and Canada. Closely related resident populations (known as rainbow trout) may be an effective resource in the recovery of these declining migratory populations. However, the extent to which different populations of resident rainbow trout produce migratory individuals and how likely these individuals are to return as adults to spawn remains unknown.
