Few studies have investigated the late (i.e. ≥ 5 years post-treatment) effects of chemotherapy for non-central nervous system (non-CNS) cancer on the brain. Here we discuss the studies that have investigated the late effects of adjuvant chemotherapy for non-CNS cancer on cognitive function (n=6); brain structure and function (n=5); and incidence of dementia (n=4). The neuropsychological studies showed long-term adverse cognitive problems in chemotherapy-exposed breast cancer survivors. This is in line with results from neuroimaging studies that report long-term brain structural alterations after chemotherapy. The studies exploring the association between chemotherapy and the incidence of dementia were contradictive and showed no clear relationship between the two phenomena. Although several methodological issues limit the validity and interpretation of some of the results of these studies, they suggest that chemotherapy is associated with subtle, yet long-lasting cognitive deficits, possibly related to brain structural and functional differences, but as yet not with an increased risk of dementia.

Background: TRK-inhibitors have demonstrated efficacy across several cancers with NTRK fusions. Their activity in cancers with NTRK overexpression remains unclear.
Methods: This trial enrolled patients with advanced cancers harboring NTRK fusions or extreme mRNA overexpression, defined as NTRK1/2/3 expression by RNA profiling >5 SDs for a given cancer type.

Neuroinflammation is a key factor in cognitive and behavioral changes seen in patients with non-CNS cancers, and cytokine levels in the blood are often used as a proxy for brain inflammation. However, this approach has yielded inconsistent results, and a common inflammatory signature remains elusive. To explore whether a blood-to-brain inflammatory signature exists across breast cancer types, we assessed cytokine and glial protein responses in the hippocampus, prefrontal cortex (PFC), and their relationship to serum cytokines in mice bearing three different mammary cancers (n = 40).

Background: Current paediatric cancer care requires innovative approaches to predict prognosis that facilitates personalised stratification, yet studies on the performance, composition and limitations of contemporary prognostic models are lacking. We aimed to compare the accuracy of traditional and advanced prognostic models.
Methods: A systematic search for this systematic review and meta-analysis (CRTN42022370251) was conducted in PubMed, Embase, Scopus, and the Cochrane Library databases on 28 June 2024.
