ABSTRACT

Children with acute lymphoblastic leukaemia (ALL) are at risk for obesity and cardiometabolic diseases. To gain insight into body composition changes among children with ALL, we assessed quantitative computed tomography (QCT) data for specific body compartments (subcutaneous adipose tissue [SAT], visceral adipose tissue [VAT], total adipose tissue [TAT], lean tissue [LT], LT/TAT and VAT/SAT at lumbar vertebrae L1 and L2) at diagnosis and at off-therapy for 189 children with ALL and evaluated associations between body mass index (BMI) Z-score and clinical characteristics. BMI Z-score correlated positively with SAT, VAT and TAT and negatively with LT/TAT and VAT/SAT. At off-therapy, BMI Z-score, SAT, VAT and TAT values were higher than at diagnosis, but LT, LT/TAT and VAT/SAT were lower. Patients aged ≥10 years at diagnosis had higher SAT, VAT and TAT and lower LT and LT/TAT than patients aged 2.0-9.9 years. Female patients had lower LT and LT/TAT than male patients. Black patients had less VAT than White patients. QCT analysis showed increases in adipose tissue and decreases in LT during ALL therapy when BMI Z-scores increased. Early dietary and physical therapy interventions should be considered, particularly for patients at risk for obesity.

ABSTRACT

Children with acute lymphoblastic leukemia (ALL) now have a five-year survival rate of 80-90% thanks to advances in risk-directed treatment and supportive care. Further, as the number of childhood ALL survivors grows, much emphasis should be directed to their after-treatment life quality, which largely depends on later complications. By removing cranial radiation, the likelihood of severe late problems such as second malignant neoplasm and endocrine disease was reduced. The risk for neurocognitive dysfunction was also reduced. However, among ALL survivors who have only received chemotherapy, there is still a risk of neurocognitive impairment. Although their overall cognitive abilities have been intact, individuals exhibit domain-specific neurocognitive impairment, which needs a thorough evaluation. Therefore, it now became more challenging to elucidate their neurocognitive dysfunction. The neurocognitive function of ALL survivors treated just with chemotherapy will be reviewed.

ABSTRACT

Little is known about body composition changes in patients with acute myeloid leukemia (AML) during and after treatment or their associations with outcomes. Z-scores for body mass index (BMI), weight, and height at diagnosis, their longitudinal changes from diagnosis to 5 years off therapy, and their associations with adverse effects and outcomes were evaluated in 227 pediatric patients with AML enrolled in the AML02 and AML08 trials at St. Jude Children's Research Hospital between 2002-2017. The median Z-scores for baseline weight, height, and BMI were 0.193, 0.209, and 0.170, respectively, and those for weight and height decreased significantly during therapy to -0.038 and -0.163, respectively, at off-therapy (P < .001 for both). At 5 years off therapy, the Z-scores for weight and BMI had increased significantly to 0.492 (P = .003) and 0.911 (P < .001), respectively, whereas the height Z-score remained significantly lower at -0.066 (P < .001) compared with baseline. The height Z-score of transplant recipients decreased further from -0.211 at transplant to -0.617 12 months later (P < .001). Baseline BMI category and Z-score were not associated with outcomes, but higher weight Z-scores were associated with lower incidences of refractory or relapsed disease (hazard ratio [HR], 0.82; 95% confidence interval [CI], 0.67-0.99) and higher incidences of death in remission (HR, 1.31; 95% CI, 1.01-1.70). Furthermore, weight Z-score decrease during induction therapy was associated with gastrointestinal, hepatic, and infection toxicities during subsequent therapy and with death in remission (HR, 2.66; 95% CI, 1.11-6.45). Multidisciplinary monitoring for weight changes and short stature is required from diagnosis to the off-therapy period.

ABSTRACT

BACKGROUND: Neurocognitive impairment and obesity are common adverse sequelae in survivors of childhood acute lymphoblastic leukemia (ALL); however, the association has not been investigated. METHODS: Neurocognitive function was evaluated once in survivors of ALL who were at least 8 years old and 5 years from their diagnosis. In a cross-sectional analysis, the associations with the body mass index (BMI) category and Z score were examined. A longitudinal analysis used the overweight/obesity area under the curve (AUC), which was determined via the trapezoidal rule by a sum of the integrals defined by the BMI Z score at each time point and the time intervals of the BMI measurement. RESULTS: For 210 survivors, the median BMI Z score at diagnosis was 0.17, which increased to 0.54 at the end of induction and to 0.74 at the neurocognitive assessment. In the cross-sectional analysis, overweight/obese survivors scored significantly lower than others on the measures of executive function (cognitive flexibility, planning, verbal fluency, working memory, and spatial construction; all P < .05), attention (attention span and risk taking; all P < .05), and processing speed (visual motor coordination, visual speed, and motor speed; all P < .05). In the longitudinal analysis, when the treatment period was subdivided into 4 time periods (induction, consolidation, early maintenance, and late maintenance), a greater overweight/obesity AUC during induction therapy was associated with worse cognitive flexibility (P = .01) and slower motor speed (P = .02), which persisted throughout the treatment. CONCLUSIONS: Overweight/obesity was significantly associated with neurocognitive impairment during long-term follow-up, and this association started early in treatment for ALL. Novel early interventions to provide cognitive training and prevent weight gain are required for patients at risk.

ABSTRACT

OBJECTIVE: To evaluate the diagnostic yield of baseline chest radiographs (CXRs) of children with acute lymphoblastic leukemia (ALL). STUDY DESIGN: We reviewed the CXR findings at diagnosis for 990 patients aged 1-18 years with ALL treated during the Total XV and XVI studies at St. Jude Children's Research Hospital and evaluated the associations of these findings with clinical characteristics and initial management. RESULTS: Common findings were peribronchial/perihilar thickening (n = 187 [19.0%]), pulmonary opacity/infiltrate (n = 159 [16.1%]), pleural effusion/thickening (n = 109 [11.1%]), mediastinal mass (n = 107 [10.9%]), and cardiomegaly (n = 68 [6.9%]). Portable CXRs provided results comparable with those obtained with 2-view films. Forty of 107 patients with a mediastinal mass (37.4%) had tracheal deviation/compression. Mediastinal mass, pleural effusion/thickening, and tracheal deviation/compression were more often associated with T-cell ALL than with B-cell ALL (P < .001 for all). Pulmonary opacity/infiltrate was associated with younger age (P = .003) and was more common in T-cell ALL than in B-cell ALL (P = .001). Peribronchial/perihilar thickening was associated with younger age (P < .001) and with positive central nervous system disease (P = .012). Patients with cardiomegaly were younger (P = .031), more often black than white (P = .007), and more often categorized as low risk than standard/high risk (P = .017). Patients with a mediastinal mass, pleural effusion/thickening, tracheal deviation/compression, or pulmonary opacity/infiltrate were more likely to receive less invasive sedation and more intensive care unit admissions and respiratory support (P ≤ .001 for all). Cardiomegaly was associated with intensive care unit admission (P = .008). No patients died of cardiorespiratory events during the initial 7 days of management. CONCLUSIONS: The CXR can detect various intrathoracic lesions and is helpful in planning initial management.

ABSTRACT

Nuclear factor (NF)-κB essential modifier (NEMO), also known as IκB kinase subunit-γ (IKKγ), is a pivotal molecule in the NF-κB signaling pathway. Mutations of NEMO cause incontinentia pigmenti and X-linked ectodermal dysplasia with immunodeficiency. Mendelian susceptibility to mycobacterial diseases (MSMD), which confers an almost selective predisposition to mycobacterial infection, is also caused by NEMO mutations. We herein report the first case of a patient with X-linked recessive (XR) MSMD who developed cutaneous squamous cell carcinoma, thyroid cancer and Langerhans cell histiocytosis. The relationship between NEMO mutation and oncogenesis is discussed.
