OBJECTIVE: Complaints about cognitive dysfunction (CD) reportedly persist in approximately one third of breast cancer patients but the nature of CD and possible risk factors are unknown. METHODS: A cross-sectional, multicenter study was set-up at 9 German oncological rehabilitation centers. Objective cognitive performance was assessed by the NeuroCog FX test, a short computerized screening (duration <30 min) which assesses working memory, alertness, verbal/figural memory and language/executive...

PURPOSE: The purpose of this study was to determine the evolution of neurocognitive problems from therapy completion to long-term follow-up in survivors of childhood acute lymphoblastic leukemia treated with chemotherapy only. METHODS: We evaluated whether attention problems observed at therapy completion evolve into long-term executive dysfunction in 158 survivors treated on a single institution protocol. Treatment data (high-dose intravenous methotrexate exposure [serum concentration] and triple intrathecal chemotherapy injections) were collected...

Esophageal adenocarcinoma (EAC) accounts for the most esophageal cancer cases in the US, and is notoriously aggressive. This study examines the role of Sonic Hedgehog (SHh)/Gli signaling in the regulation of epithelial-mesenchymal transition (EMT), a process tied to invasion and metastasis, in EAC. Gli/EMT protein expression levels were examined by western blot in paired EAC patient tissues ( n = 24) and cell lines (OE19, OE33). Functional analyses were performed (siRNA, treatment with Gli-inhibitor, AKT-inhibitor, and N-Shh recombinant proteins) to investigate SHh/Gli signaling and EMT, cell cycle, and prognostic markers in EAC cell lines...

SIGNIFICANCE: B cell lymphoma-2 (Bcl-2) was discovered over three decades ago and is the prototype antiapoptotic member of the Bcl-2 family that comprises proteins with contrasting effects on cell fate. First identified as a consequence of chromosomal translocation (t 14:18) in human lymphoma, subsequent studies have revealed mutations and/or gene copy number alterations as well as posttranslational modifications of Bcl-2 in a variety of human cancers. The canonical function of Bcl-2 is linked to its ability to inhibit mitochondrial membrane permeabilization, thereby regulating apoptosome assembly and activation by blocking the cytosolic translocation of death amplification factors...

A wide array of central nervous system complications, neurological deficits, and cognitive impairments occur and persist as a result of systemic cancer and cancer treatments. This condition is known as chemo brain and it affects over half of cancer survivors. Recent studies reported that cognitive impairments manifest before chemotherapy and are much broader than chemo brain alone, thereby adding in tumor brain as a component. The molecular mechanisms of chemo brain are under-investigated, and the mechanisms of tumor brain have not been analyzed at all...

Brain tumor patients treated with radiotherapy (RT) often develop cognitive dysfunction, and recent studies suggest that the APOE ε-4 allele may influence cognitive outcome. The ε-4 allele is known to promote beta (β) amyloid deposition in the cortex, and preliminary evidence suggests that RT may be associated with this process. However, it is unknown whether β-amyloid accumulation contributes to treatment neurotoxicity. In this pilot study, we assessed neuropsychological functions and β-amyloid retention using18 F-florbetaben (FBB) PET in a subset of brain tumor patients who participated in our study of APOE polymorphisms and cognitive functions...

In this study, we seek to longitudinally investigate the network-level functional connectivity (FC) alternations and its association with irradiation dose and cognition changes in the early stage post radiotherapy (RT) in nasopharyngeal carcinoma (NPC) patients. We performed independent component analysis (ICA) of resting state blood oxygen level-dependent functional magnetic resonance imaging (BOLD-fMRI) from 39 newly diagnosed NPC patients before receiving treatment (baseline), and 3 months post-RT. the default mode network (DMN), salience network (SN), and executive control network (ECN) were extracted with well-validated software (GIFT)...

Women with breast cancer can experience persisting cognitive deficits post treatment. We conducted a multilevel meta-analysis of cognitive function in survivors treated with chemotherapy (Ch+) to estimate the magnitude of cognitive impairment relative to healthy (HC) and chemo-negative (Ch-) controls. Seventy-two studies published up to October 2016 involving 2939 Ch+ yielded 1594 effect sizes. Ch+ demonstrated overall cognitive impairment in comparison with HC but not with Ch-. Relative to HC, Ch+ showed impairment in attention/concentration, processing speed, language, immediate recall, delayed recall, and executive function...

PURPOSE: Cognitive symptoms are common after cancer, but poorly associated with neuropsychological results. We previously reported colorectal cancer (CRC) patients had more cognitive impairment than controls. Here, we explore relationships between cognitive symptoms and neuropsychological domains. METHODS: Subjects with CRC (N = 362) and 72 healthy controls completed neuropsychological assessments and Functional Assessment of Cancer Therapy-Cognition (FACT-COG) at baseline (pre-chemotherapy) and 6, 12, and 24 months...

PURPOSE: The purpose of the study was to evaluate subjective (self-rated), family-rated, and objective (researcher-rated) cognitive functions in patients with breast cancer after chemotherapy. METHOD: We conducted a prospective study to trace self-rated cognitive functions in 30 patients with breast cancer at the completion of chemotherapy (T0) and 6 months later (T1). Subjective cognitive functions were assessed with Cognitive Failures Questionnaire (CFQ), Dysexecutive Questionnaire (DEX-S), and Everyday Memory Checklist (EMC-S) for attention, executive function, and episodic memory, respectively...

Knowledge about cognitive late effects in survivors of childhood acute lymphoblastic leukemia (ALL) is largely based on standardized neuropsychological measures and parent reports. To examine whether cognitive neuroscience paradigms provided additional insights into neurocognitive and behavioral late effects in ALL survivors, we assessed cognition and behavior using a selection of cognitive neuroscience tasks and standardized measures probing domains previously demonstrated to be affected by chemotherapy. 130 ALL survivors and 158 control subjects, between 8 and 18 years old at time of testing, completed the n-back (working memory) and stop-signal (response inhibition) tasks...

BACKGROUND: Children with non-Hodgkin lymphoma (NHL) undergo treatment with central nervous system-directed therapy, the potentially neurotoxic effects of which have not been reported in NHL survivors. METHODS: NHL survivors (n = 187) participating in the St. Jude Lifetime Cohort who were 10 or more years from their diagnosis and were 18 years old or older underwent neurocognitive, emotional distress (Brief Symptom Inventory 18), and health-related quality of life (HRQOL) assessments (36-Item Short Form Health Survey)...

Gastric cancer (GC) is one of the most common tumors worldwide. Standard treatment after early detection involves surgical excision (recurrence is possible), and metastatic gastric cancer is refractory to immuno-, radio-, and most harmful chemotherapies. Various natural compounds have shown efficacy in killing different cancers, albeit not always specifically. In this study, we show that dandelion root extract (DRE) specifically and effectively suppresses proliferation and migration in human gastric cells without inducing toxicity in noncancerous cells...

REVIEW
Christie Yao, Lori J Bernstein, Jill B Rich
PURPOSE: Women with breast cancer have reported adverse cognitive effects following chemotherapy. Evidence is mixed on whether executive functioning is particularly impaired in women treated with chemotherapy, in part due to the wide range of tasks used to measure executive processes. We performed a systematic review of the published literature to evaluate whether some subcomponents of executive functioning are more vulnerable to impairment than others among breast cancer survivors who had been treated with chemotherapy...

Background: Treatment of pediatric medulloblastoma is associated with known neurocognitive deficits that we hypothesize are caused by microstructural damage to frontal white matter (WM). Methods: Longitudinal MRI examinations were collected from baseline (after surgery but before therapy) to 36 months in 146 patients and at 3 time points in 72 controls. Regional analyses of frontal WM volume and diffusion tensor imaging metrics were performed and verified with tract-based spatial statistics...

Pyroptosis is a form of cell death that is critical for immunity. It can be induced by the canonical caspase-1 inflammasomes or by activation of caspase-4, -5 and -11 by cytosolic lipopolysaccharide. The caspases cleave gasdermin D (GSDMD) in its middle linker to release autoinhibition on its gasdermin-N domain, which executes pyroptosis via its pore-forming activity. GSDMD belongs to a gasdermin family that shares the pore-forming domain. The functions and mechanisms of activation of other gasdermins are unknown...
