OBJECTIVES: Currently, there are no studies that have established the self-perceived cognitive trajectories experienced by breast cancer patients (BCPs) post-chemotherapy. Therefore, we characterized the long-term trajectory of self-perceived cognitive function among Asian early-stage BCPs using the minimal clinically important difference (MCID) of a subjective measure of cognitive function. METHODS: Early-stage BCPs who received chemotherapy were recruited and assessed at four time points: Before chemotherapy initiation (T1), 6 weeks post-chemotherapy initiation (T2), 12 weeks post-chemotherapy initiation (T3), and 15-months post-chemotherapy initiation (T4)...

A boy with central nervous system relapse of Burkitt leukemia developed fever and neurological symptoms and cognitive impairment. He had received multi-drug chemotherapy including rituximab. Enterovirus (EV) was detected in cerebrospinal fluid by polymerase chain reaction, and magnetic resonance imaging findings were consistent with viral infection. The patient was treated with intravenous immunoglobulin and within 1 month cleared his EV. Rituximab can cause a profound B-cell deficiency predisposing patients to infections including EV encephalitis...

PURPOSE: Cancer-related fatigue (CRF) and chemotherapy-related cognitive impairment (CRCI) are reported to be associated with mitochondrial dysfunction. Hence, mitochondrial DNA (mtDNA) content, a biomarker of mitochondrial dysfunction, is hypothesized to correlate with the onset of CRF and CRCI. This study aims to evaluate the association between peripheral blood mtDNA content reduction and severity of CRF and CRCI in patients receiving chemotherapy. METHODS: This was a prospective cohort study...

BACKGROUND: Preliminary evidence suggests that changes in plasma brain-derived neurotrophic factor (BDNF) levels may contribute to the occurrence of chemotherapy-associated cognitive impairment (CACI), and a previous study suggested that carriers of the BDNF Met homozygous genotype are protected from CACI. METHODS: This multicenter, prospective cohort study involved chemotherapy-receiving early-stage breast cancer (ESBC) patients. Self-perceived cognitive function was longitudinally assessed using the validated FACT-Cog (ver...

Attention and memory dysfunction is a common complaint among patients with breast cancer that can be reported during and up to several years after treatment. It can negatively affect patients' quality of life and their ability to work. This phenomenon has mainly been studied in patients with breast cancer who are treated with adjuvant chemotherapy. Women describe concentration problems and difficulties with word finding, multitasking, or remembering new information, as well as more effort and time needed to accomplish these tasks...

Acute lymphoblastic leukemia (ALL) is the most prevalent childhood cancer and accounts for 26.8% of cancer diagnoses among children, worldwide-approximately 3,000 children each year. While advancements in treating ALL have led to a remission rate of more than 90%, many survivors experience adverse neurocognitive and/or neurobehavioral effects as a result of intrathecal chemotherapy. Methotrexate (MTX) is commonly administered with cytosine arabinoside (AraC, cytarabine) during intrathecal chemotherapy for ALL...

Post-chemotherapy cognitive impairment, or PCCI, is a common complaint, particularly among breast cancer patients. However, the exact nature of PCCI appears complex. To model the human condition, ovariectomized C57BL/6J mice were treated iv weekly for 4 weeks with saline, 2 mg/kg doxorubicin (DOX), 50 mg/kg cyclophosphamide (CYP), or DOX+CYP. For the subsequent 10 weeks, mice were assessed on several behavioral tests, including those measuring spatial learning and memory. After sacrifice, hippocampal spine density and morphology in the dentate gyrus, CA1, and CA3 regions were measured...

A 48 year-old man with lung squamous cell carcinoma was admitted to acute care with cognitive impairment after recent chemotherapy. He developed myoclonus, ataxia, agitation, and visual hallucinations. Morvan's Syndrome, a rare voltage-gated potassium channel antibody disorder characterized by neuromyotonia with central nervous system dysfunction, was eventually diagnosed. He received plasmapheresis and was admitted to inpatient rehabilitation, where he safely participated in therapies. By focusing on neuromuscular rehabilitation, balance training, fine motor skills, and cognitive retraining emphasizing skills relevant to the patient's premorbid cognitive activities, the patient demonstrated significant functional improvement, decreasing the burden of care of his caregivers...

A substantial number of cancer survivors who undergo chemotherapy report cognitive disturbances that severely limit daily function (chemobrain). Despite supportive neuropsychological evidence, there is controversy over whether cognitive impairment is caused by the chemotherapy or is the result of potentially confounding factors that include the disease itself, age, and psychological stress. Our research program, conducted on rodents, has confirmed that a range of cognitive processes, mediated in particular by hippocampal and prefrontal brain regions, are affected by anticancer drugs in combination with tumor development and that many of the effects are long lasting...

PURPOSE OF REVIEW: Neurologic problems resulting from systemic cancer metastases to brain parenchyma, dura, spinal cord, and leptomeninges are among the most common types of consultations addressed by neurologists. With patients surviving longer from systemic cancer, along with the rapidly evolving therapeutic options, the treatment of these devastating complications has become both more effective and more complicated. This article reviews current patterns of metastatic disease and the increasingly nuanced landscape of evolving therapies, their complications, and their impact on quality of survival...

PURPOSE OF REVIEW: Low-grade gliomas present vexing management issues for neuro-oncologists. The relatively long survival compared to other brain tumors makes consideration of treatment toxicity, and thus timing of potentially damaging interventions such as surgery, radiation, and chemotherapy, crucial. Moreover, the rarity of these tumors makes clinical trials to ascertain optimal care challenging. RECENT FINDINGS: The discovery that most low-grade gliomas harbor isocitrate dehydrogenase (IDH) mutations that confer a favorable prognosis has improved diagnosis and risk stratification of these tumors...

We aimed to determine if resting state functional magnetic resonance imaging (fMRI) acquired at pre-treatment baseline could accurately predict breast cancer-related cognitive impairment at long-term follow-up. We evaluated 31 patients with breast cancer (age 34-65) prior to any treatment, post-chemotherapy and 1 year later. Cognitive testing scores were normalized based on data obtained from 43 healthy female controls and then used to categorize patients as impaired or not based on longitudinal changes. We measured clustering coefficient, a measure of local connectivity, by applying graph theory to baseline resting state fMRI and entered these metrics along with relevant patient-related and medical variables into random forest classification...
