Abstract
The purpose of this study is to observe the changes of cortical morphological characteristics and their potential contribution to cognitive function in ALL survivors by using surface-based morphometry (SBM). Using SBM analysis, we calculated and compared group differences in cortical thickness, sulcal depth, gyrification, and fractal dimension of the cerebral cortex between 18 pediatric ALL survivors treated on chemotherapy-only protocols and off treatment within 2 years, and 18 healthy controls (HCs) with two-sample t-tests [P < 0.05, family-wise error (FWE) corrected]. Relationships between abnormal cortical characteristic values and cognitive function parameters were investigated with partial correlation analysis, taking age as a covariate. We found decreased cortical thickness mainly located in the prefrontal and temporal region, and increased sulcal depth in left rostral middle frontal cortex and left pars orbitalis in the ALL survivors compared to HCs. There were no statistically significant differences in the gyrification and fractal dimension between the two groups. In ALL survivors, cortical thickness and sulcal depth of above areas values revealed no significant correlation with the cognitive function parameters. In conclusion, pediatric ALL survivors show decreased cortical thickness in prefrontal and temporal regions, and increased sulcal depth in prefrontal region. These results suggest that SBM-based approach can be used to assess changes of cortical morphological characteristics in pediatric ALL survivors.

Characterizing academic performance in pediatric acute lymphoblastic leukemia with population-based achievement tests. Cancer Rep (Hoboken) 2021; 5:e1560.

Abstract
BACKGROUND Recent shifts from radiation to chemotherapy-based treatment for acute lymphoblastic leukemia (ALL) have contributed to reduced long-term morbidity. Despite this, ALL survivors remain at increased risk for long-term cognitive impairments. AIM To identify demographic and treatment factors associated with school performance in pediatric survivors of ALL. METHODS We collected standardized test scores for reading, math, and science obtained in a school setting from grades 3-11 in 63 ALL survivors (46.0% boys). Most participants were assessed across multiple grades (median number of grades n = 5, range 1-7), and 269 observations were considered in the analyses. Treatment exposures were extracted from medical records. Socio-economic status was estimated using participation in free/reduced lunch programs at school. Mixed effects linear regression models were conducted to determine factors associated with school performance. RESULTS ALL survivors' scores were comparable to state norms on reading, math, and science performances. On multivariable analysis, participation in free/reduced lunch programs was significantly associated with lower reading scores (β = -12.52; 95% CI -22.26:-2.77, p = .01). Exposure to radiation during treatment was also associated with lower reading test scores (β = -30.81, 95% CI -52.00:-9.62, p = .01). No significant associations between demographics and treatment parameters were observed for math and science test scores. CONCLUSIONS We utilized population-based achievement tests conducted from grades 3-11 to characterize school performance in ALL survivors. Our results imply that survivors with low socio-economic status and those exposed to radiation during treatment could benefit from early monitoring and intervention to maximize academic success.

Abstract
Survival rates of childhood acute lymphoblastic leukemia (ALL) have improved greatly due to advanced therapies and supportive care. Intrathecal chemotherapy replaced cranial radiation due to radiation-induced neurotoxicity and late-effects. Survivors treated with chemotherapy-only experience neurologic and cognitive problems following cessation of treatment. Very long-term cognitive outcomes remain unclear. Animal models are being generated to assess late-effects of chemotherapy on cognitive function. Although, few address juvenile models of chemotherapy-induced cognitive impairment (CICI) and developing brain, results of this review outline neurocognitive effects of chemotherapy consistent with childhood ALL therapy. Studies demonstrate deficits across cognitive domains including spatial memory, executive function, short-term memory, anxiety and depression. Inflammation, oxidative stress, excitotoxity, and other metabolic disruptions may lead to neurodegeneration associated with cognitive impairment observed in ALL survivors. Interventions directly targeting these mechanisms may prevent and/or promote recovery of cognitive function and improve long-term outcomes. Evidence suggests success of anti-inflammatory and antioxidant treatments in reducing cognitive decline. Animal models provide basis for assessing effects of chemotherapy on neurologic processes to guide future clinical investigations.

Quantitative MRI outcomes in child and adolescent leukemia survivors: Evidence for global alterations in gray and white matter. NEUROIMAGE-CLINICAL 2020; 28:102428. [PMID: 32980598 PMCID: PMC7522853 DOI: 10.1016/j.nicl.2020.102428] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/11/2020] [Revised: 08/22/2020] [Accepted: 09/08/2020] [Indexed: 12/19/2022]
Abstract
Studies of cognition in ALL survivors consistently show evidence of mild neurocognitive difficulties. Structural MRI showed widespread differences between survivors and controls. Gray and white matter volumes were respectively 5 and 6% smaller in survivors. Survivors also exhibited altered white matter diffusion overall.
Introduction Cure rates for pediatric acute lymphoblastic leukemia (ALL) have reached an all-time high (>90%); however, neurocognitive difficulties continue to affect quality of life in at least a subset of survivors. There are relatively few quantitative neuroimaging studies in child and adolescent ALL survivors treated with chemotherapy only. Use of different outcome measures or limited sample sizes restrict our ability to make inferences about patterns of brain development following chemotherapy treatment. In this study, we used magnetic resonance imaging (MRI) to evaluate brain outcomes in ALL survivors, comparing against a group of typically developing, cancer free peers. Materials and methods Participants included 71 ALL survivors, on average 8 years after diagnosis and 8–18 years of age, and 83 typically developing controls. Anatomical MRI was performed to evaluate brain structure; diffusion and magnetization transfer MRI were used to examine brain tissue microstructure. Results Successful MRI scans were acquired in 67 survivors (94%) and 82 controls (99%). Structurally, ALL survivors exhibited widespread reductions in brain volume, with 6% less white matter and 5% less gray matter than controls (p = 0.003 and 0.0006 respectively). Much of the brain appeared affected – 71 of 90 evaluated structures showed smaller volume – with the most notable exception being the occipital lobe, where no significant differences were observed. Average full-scale IQ in the survivor and control groups were 95 (CI 92–99) and 110 (CI 107–113), respectively. Using data from the NIH Pediatric MRI Data Repository, we evaluated the extent to which elevated IQ in the control group might affect the structural differences observed. We estimated that two thirds of the observed brain differences were attributable to ALL and its treatment. In addition to the structural changes, survivors showed, on average, globally lower white matter fractional anisotropy (-3%) and higher radial diffusivity (+5%) (p < 10−6), but no differences in magnetization transfer ratio. Conclusions Neuroanatomical alterations in late childhood and adolescent ALL survivors treated with chemotherapy-only protocols are widespread, with white matter being somewhat more affected than gray matter. These MRI results indicate brain development is altered in ALL survivors and highlight the need to examine how these alterations emerge.

Abstract
BACKGROUND The purpose was to examine associations between treatment and chronic health conditions with neurocognitive impairment survivors of acute lymphoblastic leukemia (ALL) treated with chemotherapy only. METHODS This cross-sectional study included 1207 ALL survivors (54.0% female; mean age 30.6 years) and 2273 siblings (56.9% female; mean age 47.6 years), who completed the Childhood Cancer Survivor Study Neurocognitive Questionnaire. Multivariable logistic regression compared prevalence of neurocognitive impairment between survivors and siblings by sex. Associations between neurocognitive impairment with treatment exposures and chronic conditions (graded according to Common Terminology Criteria for Adverse Events) were also examined. Statistical tests were 2-sided. RESULTS Relative to same-sex siblings, male and female ALL survivors reported increased prevalence of impaired task efficiency (males: 11.7% vs 16.9%; adjusted odds ratio [OR] = 1.89, 95% confidence interval [CI] = 1.31 to 2.74; females: 12.5% vs 17.6%; OR = 1.50, 95% CI = 1.07 to 2.14), as well as impaired memory (males: 11.6% vs 19.9%, OR = 1.89, CI = 1.31 to 2.74; females: 14.78% vs 25.4%, OR = 1.96, 95% CI = 1.43 to 2.70, respectively). Among male survivors, impaired task efficiency was associated with 2-4 neurologic conditions (OR = 4.33, 95% CI = 1.76 to 10.68) and with pulmonary conditions (OR = 4.99, 95% CI = 1.51 to 16.50), and impaired memory was associated with increased cumulative dose of intrathecal methotrexate (OR = 1.68, 95% CI = 1.16 to 2.46) and with exposure to dexamethasone (OR = 2.44, 95% CI = 1.19 to 5.01). In female survivors, grade 2-4 endocrine conditions were associated with higher risk of impaired task efficiency (OR = 2.19, 95% CI = 1.20 to 3.97) and memory (OR = 2.26, 95% CI = 1.31 to 3.92). CONCLUSION Neurocognitive impairment is associated with methotrexate, dexamethasone, and chronic health conditions in a sex-specific manner, highlighting the need to investigate physiological mechanisms and monitor impact through survivorship.

Switching to Bortezomib may Improve Recovery From Severe Vincristine Neuropathy in Pediatric Acute Lymphoblastic Leukemia. J Pediatr Hematol Oncol 2019; 41:457-462.

Abstract
PURPOSE The purpose of this study was to evaluate the impact of switching patients being treated for acute lymphoblastic leukemia (ALL) from vincristine to bortezomib. PATIENTS AND METHODS A total of 20 patients with ALL were switched from vincristine to bortezomib (1.3 mg/m/dose) because of worsening neuropathy despite physical therapy interventions (n=18) or at increased risk of neuropathy (n=2). Relapse rates were compared with 56 vincristine-only patients matched by prognostic factors. Maintenance blood counts in bortezomib patients were compared with cooperative group data using vincristine during maintenance. In addition, 6 evaluable patients were assessed for neuropathy using the pediatric-modified total neuropathy score. Neuropathy scores were collected during treatment with vincristine and after switching to bortezomib. RESULTS After a median follow-up of 3.5 years the relapse rate in patients switched to bortezomib was nonsignificantly different than those remaining on vincristine. Patients on monthly bortezomib had statistically significantly lower platelet counts that did not require transfusions or dose adjustment. Total neuropathy for all 6 cases decreased significantly when switched to bortezomib from vincristine (P=0.015), with motor neuropathy declines in 5 of 6 subjects. CONCLUSIONS Bortezomib substitution for vincristine in ALL treatment is a potential strategy to mitigate severe vincristine neuropathy. These findings should be confirmed in a randomized clinical trial to further assess benefits and risks of this approach.

Abstract
West syndrome, an age-specific epileptic encephalopathy, manifests with infantile spasms (IS) and impaired neurodevelopmental outcomes and epilepsy. The multiple-hit rat model of IS is a chronic model of IS due to structural etiology, in which spasms respond partially to vigabatrin analogs. Using this model, we investigated whether IS due to structural etiology may have deficits in parvalbumin (PRV) and somatostatin (SST) immunoreactive (-ir) interneurons, and calretinin-ir (CR-ir) neurons of the primary somatosensory cortex of postnatal day (PN) 20-24 rats, using specific immunohistochemical assays. PN3 Sprague-Dawley male rats underwent the multiple-hit induction protocol, were monitored until PN20-24, and were transcardially perfused to collect brains for histology. Age-matched sham and naive control male rats were also used. Coronal brain cryosections were stained with anti-PRV, anti-CR, and anti-SST antibodies, and regions of interest (ROIs) from the primary somatosensory cortices were selected to determine PRV-, CR-, and SST-ir cell counts and cortical ROI volumes, with blinding to experimental group. Statistical analyses were done using a linear mixed model accounting for repeated measures. We found PRV-ir interneuronal selective reduction, sparing of the CR-ir and SST-ir neurons, and bilateral cortical atrophy. Our findings provide evidence for acquired PRV-selective interneuronopathy, possibly underlying the pathogenesis of IS, neurodevelopmental deficits, and epilepsy, and potentially contributing to the partial response to vigabatrin analogs in this model.
