Abstract
PURPOSE Survival rates for children diagnosed with acute lymphoblastic leukemia (ALL) have increased significantly over recent decades, and thus attention shifted toward understanding the adverse effects of cancer treatment. Chemotherapy has side effects that could affect muscle state and diminish motor performance. This scoping review was conducted to map the breadth of evidence for different tools used in fine motor skills assessment, the extent of upper extremity strength, and fine motor performance, highlighting the potential risk factors that may influence these skills. METHODS In March 2023, full-text studies that examined fine motor performance and/or upper extremity strength were identified via searches in PubMed, Science Direct, Scopus, Web of Science, and PEDro databases. The titles and abstracts of selected studies were screened according to the inclusion and exclusion criteria. RESULTS The search yielded initial 418 citations and 26 peer-reviewed articles were finally included in the review. Considerable heterogeneity was observed regarding the methods of evaluating fine motor skills. The results of this review indicate that children and adolescents with ALL experienced fine motor limitations and upper extremity weakness either during or after cessation of treatment. CONCLUSION This scoping review presents a broad overview of the literature addressing fine motor difficulties in the pediatric population with ALL. Results accentuate the need to incorporate strengthening and occupational therapy training to preserve muscle strength and minimize future fine motor problems along the course of chemotherapeutic treatment. Little evidence was reported regarding the risk factors that may impair muscle strength and motor performance.

Abstract
Peripheral neuropathy is a well described complication in children with cancer. Oncologists are generally well aware of the toxicity of the main agents, but fear the side effects of new drugs. As chemotherapeutic agents have been correlated with the activation of the immune system such as in Chemotherapy Induced Peripheral Neuropathy (CIPN), an abnormal response can lead to Autoimmune Peripheral Neuropathy (APN). Although less frequent but more severe, Radiation Induced Peripheral Neuropathy may be related to irreversible peripheral nervous system (PNS). Pediatric cancer patients also have a higher risk of entering a Pediatric Intensive Care Unit for complications related to therapy and disease. Injury to peripheral nerves is cumulative, and frequently, the additional stress of a malignancy and its therapy can unmask a subclinical neuropathy. Emerging risk factors for CIPN include treatment factors such as dose, duration and concurrent medication along with patient factors, namely age and inherited susceptibilities. The recent identification of individual genetic variations has advanced the understanding of physiopathological mechanisms and may direct future treatment approaches. More research is needed on pharmacological agents for the prevention or treatment of the condition as well as rehabilitation interventions, in order to allow for the simultaneous delivery of optimal cancer therapy and the mitigation of toxicity associated with pain and functional impairment. The aim of this paper is to review literature data regarding PNS complications in non-primary pediatric cancer.

Abstract
Skeletal muscle (muscle) is essential for physical health and for metabolic integrity, with sarcopenia (progressive muscle mass loss and weakness), a pre-curser of aging and chronic disease. Loss of lean mass and muscle quality (force generation per unit of muscle) in the general population are associated with fatigue, weakness, and slowed walking speed, eventually interfering with the ability to maintain physical independence, and impacting participation in social roles and quality of life. Muscle mass and strength impairments are also documented during childhood cancer treatment, which often persist into adult survivorship, and contribute to an aging phenotype in this vulnerable population. Although several treatment exposures appear to confer increased risk for loss of mass and strength that persists after therapy, the pathophysiology responsible for poor muscle quantity and quality is not well understood in the childhood cancer survivor population. This is partly due to limited access to both pediatric and adult survivor muscle tissue samples, and to difficulties surrounding non-invasive investigative approaches for muscle assessment. Because muscle accounts for just under half of the body's mass, and is essential for movement, metabolism and metabolic health, understanding mechanisms of injury responsible for both initial and persistent dysfunction is important, and will provide a foundation for intervention. The purpose of this review is to provide an overview of the available evidence describing associations between childhood cancer, its treatment, and muscle outcomes, identifying gaps in current knowledge.

Clinical utility of complex assessment with evoked potentials in acute lymphoblastic leukemia survivors: comparison of various treatment protocols. BMC Cancer 2021; 21:150. [PMID: 33568096 PMCID: PMC7876796 DOI: 10.1186/s12885-021-07873-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2020] [Accepted: 02/03/2021] [Indexed: 11/21/2022] Open
Abstract
BACKGROUND One of the greatest success of pediatric hematology is a prominent improvement of survival in acute lymphoblastic leukemia (ALL). Therefore, special attention needs to be paid to long-term side effects of the treatment such as neurotoxicity. One of the few diagnostic methods that allow an objective assessment of sensory systems are evoked potentials (EP). METHODS The analyzed group consisted of 167 ALL long-term survivors, aged 4.9-28.4 years, without auditory, visual and sensory deviations. Patients were treated with New York (NY, n = 35), previous modified Berlin-Frankfurt-Münster (pBFM, n = 47) and BFM95 (n = 85) protocols. In order to assess the impact of radiotherapy on recorded EP, a joint analysis of NY and pBFM groups was performed. The control group consisted of 35 patients, aged 6-17 years. The analyzed patients underwent a complex assessment with visual EP (VEP), somatosensory EP (SEP) and brainstem auditory EP (BAEP) in accordance with current standards. RESULTS ALL treatment contributed to the shortening of wave I latency (1.59 vs 1.90, P = 0.003) and prolongation of I-III (2.23 vs 2.04, P = 0.004) and I-V (4.57 vs 4.24, P = 0.002) interwave latencies of BAEP. A significant effect was also noticed in P100 (106.32 vs 101.57, P < 0.001) and N135 (151.42 vs 138.22, P < 0.001) latencies of VEP and N18 amplitude (3.24 vs 4.70, P = 0.007) and P25 latency (21.32 vs 23.39, P < 0.001) of SEP. The distribution of abnormalities between protocols was similar in BAEP (NY - 68.6%, pBFM - 61.7%, BFM95-69.4%, P = 0.650), VEP (NY - 68.6%, pBFM - 42.5%, BFM95-58.3%, P = 0.053) and significantly different for SEP (NY - 62.9%, pBFM - 36.2%, BFM95-53.0%, P = 0.045). The harmful effect of radiotherapy was most clearly marked in numerous disturbances of SEP parameters. CONCLUSIONS The presented analysis indicates a high frequency of subclinical abnormalities in EP regardless of the analyzed protocol. To our knowledge current study is the largest and one of the most complex research examining the role of EP in ALL patients. The obtained results indicate the possibility of using a single, objective and non-invasive measurement of EP in ALL survivors in order to stratify the risk of developing sensory abnormalities in adulthood.

Abstract
The surface of halloysite nanotubes (HNTs) was bifunctionalized with two ligands—folic acid and a fluorochrome. In tandem, this combination should selectively target cancer cells and provide a means for imaging the nanoparticle. Modified bi-functionalized HNTs (bi-HNTs) were then doped with the anti-cancer drug methotrexate. bi-HNTs were characterized and subjected to in vitro tests to assess cellular growth and changes in cellular behavior in three cell lines—colon cancer, osteosarcoma, and a pre-osteoblast cell line (MC3T3-E1). Cell viability, proliferation, and cell uptake efficiency were assessed. The bi-HNTs showed cytocompatibility at a wide range of concentrations. Compared with regular-sized HNTs, reduced HNTs (~6 microns) were taken up by cells in more significant amounts, but increased cytotoxicity lead to apoptosis. Multi-photon images confirmed the intracellular location of bi-HNTs, and the method of cell entry was mainly through caveolae-mediated endocytosis. The bi-HNTs showed a high drug loading efficiency with methotrexate and a prolonged period of release. Most importantly, bi-HNTs were designed as a drug carrier to target cancer cells specifically, and imaging data shows that non-cancerous cells were unaffected after exposure to MTX-doped bi-HNTs. All data provide support for our nanoparticle design as a mechanism to selectively target cancer cells and significantly reduce the side-effects caused by off-targeting of anti-cancer drugs.

Abstract
Pediatric acute lymphoblastic leukemia survivors are at risk for developing neurocognitive late effects following intensive medical treatment. Motor impairments have been highlighted as a common neurocognitive late effect, including fine-, gross-, and visual-motor skills. The severity of these motor deficits is variable in the existing literature, warranting additional investigations with more homogenous samples. In addition, there is an even greater paucity regarding the interrelations between motor deficits and the impact motor challenges may have on other domains of functioning, such as academics. Therefore, the present study aimed to characterize motor functioning in children who were treated for acute lymphoblastic leukemia with chemotherapy (n = 13) in comparison to healthy controls (n = 13). Additionally, this study investigated the relationship between primary (e.g., visual-spatial, fine-motor), secondary (e.g., visual-motor), and tertiary (e.g., academics) skills. The results revealed that oncology survivors had significantly lower fine- and gross-motor skills compared to healthy controls. No significant differences were observed between the groups on visual-perception and visual-motor tasks. Fine-motor functioning was significantly associated with visual-motor functioning in ALL survivors. Motor skills were not related to academic outcomes. The present findings provide evidence for motor impairments in pediatric ALL survivors, along with initial findings highlighting the cascading effect of primary motor impairments on other cognitive domains. This research sheds light on the need for clinical screening and intervention of motor skills in the survivorship population. Future research is warranted to examine the effect of motor deficits on cognitive and psychosocial functioning in pediatric oncology.

Abstract
PURPOSE Vincristine is widely used as anticancer therapy for a variety of hematological malignancies. The treatment is limited by progressive vincristine-induced neuropathy, possibly including both peripheral sensory and motor nerves, autonomic nervous functions, and the central nervous system. This dose-limiting side-effect can diminish quality of life and, furthermore, cause discontinuation of vincristine treatment. The present review elucidates the current knowledge regarding vincristine-induced neuropathy in hematologic malignancies, focusing on neuropathy assessment, clinical and molecular predictive markers, drug-drug interference, prevention, and treatment. METHODS This review is conducted by a systematic search strategy for the identification of relevant literature in the PubMed and Embase databases. RESULTS No clinical parameters displayed convincing potential as predictors of vincristine-induced neuropathy; however, preexisting neuropathy was consistently reported to be associated with an increased risk of neurotoxicity. In contrast, molecular markers, including polymorphisms in genes involved in the pharmacodynamics and pharmacokinetics of vincristine, displayed great potential as predictive markers of neuropathy incidence and severity. Furthermore, antifungal drugs, such as itraconazole and voriconazole, decrease the metabolism of vincristine and consequently lead to severe neuropathy when co-administered with vincristine, underscoring why fluconazole should be the antifungal drug of choice. CONCLUSION Reports from the 71 included studies clearly emphasize the lack of consistency in neuropathy assessment, grading systems, and reporting, making it difficult to interpret results between studies. Thus, truer clinical and molecular markers could emerge if the consistency of neuropathy detection and reporting increases by the use of conventional standardized neuropathy assessment tools and grading scales.

Abstract
BACKGROUND Up to 43% of survivors of pediatric acute lymphoblastic leukemia (ALL) may exhibit fine-motor problems. Information on manual dexterity in this cohort is still limited. OBJECTIVES We tested survivors of childhood ALL treated with chemotherapy-only for fine-motor function in terms of drawing and handwriting abilities using a Digitizing Tablet (DT) with three tasks for drawing and handwriting of varying complexity, for ataxia using the International Cooperative Ataxia Rating Scale (ICARS), and for tremor and hand-eye coordination using the Nine Hole Steadiness Tester (NHST). RESULTS We examined a cohort of non-irradiated survivors (n = 31) after a median time of 3.5 years after end of therapy. In all tasks of the DT the cohort demonstrated significant (p < 0.05) impairment of speed, automation, and variability in at least two tasks and significantly more pressure. Impaired speed (SPV) inversely correlated with lag time since end of therapy. Dexterity performance of six survivors (19%) lay below the 5th percentile. No survivor exhibited ataxia, tremor, or impaired hand-steadiness. CONCLUSION Despite the absence of gross ataxia, tremor, and impaired hand-eye coordination, we nevertheless detected significant fine-motor impairment in a relevant number of survivors of childhood ALL. Prospective studies are needed to reveal the pathophysiological underpinnings and genetic risk factors for development of such deficits due to ALL and its treatment.

Abstract
BACKGROUND The early effects of childhood acute lymphoblastic leukemia (ALL) include decreased physical function, bone mineral density (BMD/g/cm2 ), and health-related quality of life (HRQL). We assessed the capacity of a physical therapy and motivation-based intervention, beginning after diagnosis and continuing through the end of treatment, to positively modify these factors. PROCEDURE A 2.5-year randomized controlled trial of 73 patients aged 4-18.99 years within 10 days of ALL diagnosis assessed BMD at baseline (T0 ) and end of therapy (T3 ), strength, range of motion, endurance, motor skills, and HRQL at baseline (T0 ), 8 (T1 ), 15 (T2 ), and 135 (T3 ) weeks. RESULTS There were no significant changes between groups (intervention, n = 33; usual care, n = 40) in BMD (P = 0.059) at T3 or physical function and HRQL at T0 -T3 . While BMD declined in both the intervention (T0 = -0.21, T3 = -0.55) and usual care (T0 = -0.62, T3 = -0.78) groups, rates of decline did not differ between groups (P = 0.56). Univariate analysis (n = 73) showed associations of higher T3 bone density with body mass index T1 (P = 0.01), T2 (P = <0.0001), T3 (P = 0.01), T3 ankle flexibility/strength (P = 0.001), and T2 parent (P = 0.02)/T0 child (P = 0.03) perceptions of less bodily pain. CONCLUSIONS The intervention delivered during treatment was not successful in modifying BMD, physical function, or HRQL. Physical activity, at the level and intensity required to modify these factors, may not be feasible during early treatment owing to the child's responses to the disease and treatment. Future studies will consider intervention implementation during late maintenance therapy, extending into survivorship.

Abstract
BACKGROUND Treatment for acute lymphoblastic leukemia (ALL) can affect balance via different mechanisms, including sensory and motor peripheral neuropathy, cognitive impairment, and reduced muscle strength and flexibility. To provide an overview of what is currently known about the effects of cancer treatment on balance in pediatric ALL patients and survivors, and of the predictors of poor balance, a review of the literature was conducted. METHODS Five databases were searched for English-language original research articles on balance during or after treatment for pediatric ALL. RESULTS From a total of nine studies, six identified significant balance problems in children with ALL during or after treatment. The percentage of patients or survivors with impaired balance varied between 27% and 69% during treatment, 7% and 65% a few years after completion of treatment, and 14% and 17% many years after the completion of treatment. Factors associated with impaired balance were higher body mass index; higher intrathecal methotrexate dose; cranial radiation; knee extensor weakness; and impaired cognition. CONCLUSION Although heterogeneity between the studies regarding patient age; age at diagnosis; time since completion of treatment; and methods of quantifying balance make it difficult to reach a single conclusion, the evidence suggests that survivors may experience short- and/or long-term balance difficulties. While there is a need for additional studies to better understand the effects of impaired balance in survivors, clinicians treating both child and adult survivors of ALL need to be aware of these potential risks.

Abstract
This review aims to summarize the evidence for impairments of muscle strength and balance during and after treatment for childhood cancer. Thirty-two articles, identified in scientific databases by means of a structured search for investigations of muscle strength and balance in pediatric cancer patients and survivors, are evaluated. A summary of results is given with respect to matching reporting items to provide a qualitative analysis of the evidence. The majority of the studies reached a level 3 rating according to Oxford Centre for Evidence-Based Medicine (OCEBM) 2011 levels of evidence. Muscle strength and balance seem to be impaired in varying degrees depending on the diagnosis, treatment received, and time elapsed between treatment and evaluation. Drawing specific conclusions from the identified studies is difficult because of heterogeneous study samples and methods of research. Individual targeted exercise therapy programs during treatment and follow-up of childhood cancer could help to prevent and further diminish impairments of muscle strength and balance function among childhood cancer patients and survivors.

Abstract
Children treated for cancer are exposed to a variety of chemotherapeutic agents with known toxicity to the peripheral nervous system. The side effect of peripheral neuropathy can cause changes in sensation, function, and even cause pain. Although peripheral neuropathy is recognized by pediatric oncology nurses as an important and significant side effect, measuring neuropathy can be quite complex for clinical care and research efforts. With more children surviving a cancer diagnosis today, this issue is increasingly important for childhood cancer survivors. This article has reviewed existing literature examining peripheral neuropathy in childhood cancer survivors with particular interest paid to measurement tools available and needs for future research. It is important for nurses to choose appropriate measures for clinical care and research methods in order to have an impact on patients experiencing this condition.

Abstract
OBJECTIVE Assess the association between fine motor (FM) and visual-motor integration (VMI) skills and academic achievement in pediatric acute lymphoblastic leukemia (ALL) survivors. METHODS In this 28-site cross-sectional study of 256 children in first remission, a mean of 8.9 ± 2.2 years after treatment for standard-risk precursor-B ALL, validated measures of FM, VMI, reading, math, and intelligence were administered at mean follow-up age of 12.8 ± 2.5 years. RESULTS VMI was significantly associated with written math calculation ability (p < .0069) after adjusting for intelligence (p < .0001). VMI was more strongly associated with math in those with lower intelligence (p = .0141). Word decoding was also significantly associated with VMI but with no effect modification by intelligence. FM skills were not associated with either reading or math achievement. CONCLUSION These findings suggest that VMI is associated with aspects of math and reading achievement in leukemia survivors. These skills may be amenable to intervention.

Abstract
Children treated for cancer are at increased risk of developing chronic health conditions, some of which may manifest during or soon after treatment while others emerge many years after therapy. These health problems may limit physical performance and functional capacity, interfering with participation in work, social, and recreational activities. In this review, we discuss treatment-induced impairments in the endocrine, musculoskeletal, neurological, and cardiopulmonary systems and their influence on mobility and physical function. We found that cranial radiation at a young age was associated with broad range of chronic conditions including obesity, short stature, low bone mineral density and neuromotor impairments. Anthracyclines and chest radiation are associated with both short and long-term cardiotoxicity. Although numerous chronic conditions are documented among individuals treated for childhood cancer, the impact of these conditions on mobility and function are not well characterized, with most studies limited to survivors of acute lymphoblastic leukemia and brain tumors. Moving forward, further research assessing the impact of chronic conditions on participation in work and social activities is required. Moreover, interventions to prevent or ameliorate the loss of physical function among children treated for cancer are likely to become an important area of survivorship research.

Abstract
Background. Children with acute lymphoblastic leukemia receive vincristine, a chemotherapy drug known to cause peripheral neuropathy. Yet, few studies have examined the association of vincristine to fine motor function. Purpose. This study will describe the fine motor skills and function of children with acute lymphoblastic leukemia on maintenance vincristine. Method. A prospective case series design assessed manual dexterity and parent-reported fine motor dysfunction of 15 children with acute lymphoblastic leukemia in relation to cumulative vincristine exposure. Findings. Almost half of the participants had below-average fine motor skills compared to age-related norms, and 57% of parents observed functional motor problems in their children. No significant associations were found between vincristine, manual dexterity, and functional motor skills. Implications. Early detection and intervention for fine motor difficulties is suggested. Research with a larger sample is necessary to further explore the association of vincristine and fine motor function in this clinical population.

Abstract
BACKGROUND Separating out the effects of cancer and treatment between central and peripheral components of the O2 delivery chain should be of interest to clinicians for longitudinal evaluation of potential functional impairment in order to set appropriate individually tailored training/rehabilitation programmes. We propose a non-invasive method (NIRS, near infrared spectroscopy) to be used in routine clinical practice to evaluate a potential impairment of skeletal muscle oxidative capacity during exercise in children previously diagnosed with acute lymphoblastic leukaemia (ALL). The purpose of this study was to evaluate the capacity of skeletal muscle to extract O2 in 10 children diagnosed with ALL, 1 year after the end of malignancy treatment, compared to a control group matched for gender and age (mean±SD = 7.8±1.5 and 7.3±1.4 years, respectively). METHODS AND FINDINGS Participants underwent an incremental exercise test on a treadmill until exhaustion. Oxygen uptake ([Formula: see text]), heart rate (HR), and tissue oxygenation status (Δ[HHb]) of the vastus lateralis muscle evaluated by NIRS, were measured. The results showed that, in children with ALL, a significant linear regression was found by plotting [Formula: see text] vs Δ[HHb] both measured at peak of exercise. In children with ALL, the slope of the HR vs [Formula: see text] linear response (during sub-maximal and peak work rates) was negatively correlated with the peak value of Δ[HHb]. CONCLUSIONS The present study proves that the NIRS technique allows us to identify large inter-individual differences in levels of impairment in muscle O2 extraction in children with ALL. The outcome of these findings is variable and may reflect either muscle atrophy due to lack of use or, in the most severe cases, an undiagnosed myopathy.

Abstract
This study aimed to evaluate visuomotor function in children treated for acute lymphoblastic leukaemia (ALL). The performance of 64 children, 1-7 years post-chemotherapy for ALL, was compared to that of their healthy peers (n = 56) on visuomotor integration (VMI) and motor coordination (MC) tasks. Children posttreatment for ALL displayed significantly reduced VMI, but not MC, performances as compared to controls. Children treated on chemotherapy-only ALL regimes are at heightened risk for visuomotor integration deficits. Monitoring of visuomotor skills and implementation of appropriate interventions targeting higher level visuomotor integration skills should form an important component of any ALL long-term effects program.

Abstract
Bipolar affective disorder is characterized by recurring episodes of mania with or without, but commonly with, episodes of depression. It usually begins in adolescence and can cause enduring and substantial impairment if left untreated. It needs a long-term treatment with mood stabilizers to prevent relapses. Elevated or depressed mood relapses can be either primary or secondary. However, primary mood relapses can occur without a significant precipitating factor, more often tending to occur following stressful life events or discontinuation of mood stabilizer medications. Secondary mood relapses can be caused by many conditions, such as physical illnesses, substance misuse and medications. When a mental illness coexists with another physical illness and the treatment of one complicates the other, it adds complexity to the selection of appropriate pharmacological regime for either condition. In this paper, the authors present a case of bipolar affective disorder who had two episodes of mania likely precipitated by methotrexate, which were reversed by the withdrawal of the offending drug (methotrexate). To the best of the authors' knowledge, to date there have been no published reports in the literature in which methotrexate, an immunosuppressive and a cytotoxic drug, precipitated a manic episode in a patient with bipolar affective disorder.

Abstract
BACKGROUND Treatment regimens for childhood acute lymphoblastic leukemia (ALL) contain neurotoxic agents that may interfere with neuromuscular health. In this study, the authors examined associations between neuromuscular impairments and physical function and between neuromuscular impairments and doses of vincristine and intrathecal methotrexate used to treat leukemia among survivors of childhood ALL. METHODS ALL survivors >10 years from diagnosis participated in neuromuscular performance testing. Treatment data were abstracted from medical records. Regression models were used to evaluate associations between treatment factors, neuromuscular impairments, and physical performance. RESULTS Among 415 survivors (median age, 35 years; age range, 21-52 years), balance, mobility, and 6-minute walk (6MW) distances were 1.3 standard deviations below age-specific and sex-specific values in 15.4%, 3.6%, and 46.5% of participants, respectively. Impairments included absent Achilles tendon reflexes (39.5%), active dorsiflexion range of motion (ROM) <5 degrees (33.5%), and impaired knee extension strength (30.1%). In adjusted models (including cranial radiation), survivors who received cumulative intrathecal methotrexate doses ≥215 mg/m(2) were 3.4 times more likely (95% confidence interval, 1.2-9.8 times more likely) to have impaired ROM than survivors who received no intrathecal methotrexate, and survivors who received cumulative vincristine doses ≥39 mg/m(2) were 1.5 times more likely (95% CI, 1.0-2.5 times more likely) to have impaired ROM than survivors who received lower cumulative doses of vincristine. Higher intrathecal methotrexate doses were associated with reduced knee extension strength and 6MW distances. CONCLUSIONS Neuromuscular impairments were prevalent in childhood ALL survivors and interfered with physical performance. Higher cumulative doses of vincristine and/or intrathecal methotrexate were associated with long-term neuromuscular impairments, which have implications on future function as these survivors age.

Abstract
Survival of childhood acute lymphoblastic leukemia (ALL) is one of the greatest medical success stories of the last four decades. Unfortunately, childhood ALL survivors experience medical late effects that increase their risk of morbidity and premature death, often due to heart and vascular disease. Research has helped elucidate the mechanisms and trajectory of direct damage to the heart from treatment exposure, particularly to anthracyclines, and has also contributed knowledge on the influences of related chronic conditions, such as obesity and insulin resistance on heart health in these survivors. This article summarizes the key issues associated with early morbidity and mortality from cardiac-related disease in childhood ALL survivors and suggests directions for interventions to improve long-term outcomes.

Abstract
To evaluate neurological changes developing during paediatric Acute Lymphoblastic Leukaemia (ALL) therapy clinically and through electrophysiological Study of Somatosensory Evoked Potentials (SSEPs) changes in different phases of therapy. Thirty five-ALL patients with age range from 3-14 years were included compared to 30 healthy controls. History, neurological examination, complete blood counts, cytological examination of bone marrow aspirate and cerebrospinal fluid with Measurement of Serum Methotrexate (MTX) were done. The SSEPs were performed and patients subjected to another SSEP with measurement of serum MTX level before and 10 days after intra-thecal injection (IMTX). Clinical neurological findings in patients after induction were depressed deep tendon reflexes (43.3%), hypotonia (28.6%), lost pain sensation (28.6%), muscle weakness (17.1%) and movement disorders (17.1%). Percentage of delayed SSEPs after induction were at levels of brachial plexus (28.6%), spinal cord (68.6%), cortical conduction (31.4%), ERB-N13 Inter Peak Latency (IPL) (74.3%) and N13-N20 IPL (17.1%) in the studied patients. Significant prolonged latency of N13 (p = 0.005), N20 (p = 0.04) and IPL of ERB-N 13 (p = 0.005), N13-N20 (p = 0.01), Inter-Side Difference (ISD) of N13 (p = 0.01), ERB-N13 (p = 0.02) and N13-N20 (p = 0.03) after induction compared to values at diagnosis. Significant positive correlation were found between serum MTX after IMTX with N13-N20 IPL (p = 0.01), N20 ISD (p = 0.03) with significant prolongation in N20 latency, N13-N20 IPL and ISD of N20 compared to values before injection. ALL patients have prolonged latency of SSEPs at cervical cord and cortical levels which increased after IMTX due to axonal injury throughout the cord. SSEPs could be an early diagnostic tool for subclinical neuropathy.

Abstract
Children with acute lymphoblastic leukemia (ALL) are at risk for developing musculoskeletal complications. Few studies have examined the role of physical therapy (PT) for addressing these complications. The study objective was to examine why and when in the medical treatment, children with ALL receive a referral to PT. Retrospective chart review of 35 children, diagnosed with ALL in 2006 and 2007 at Penn State Children's Hospital was carried out. A questionnaire was completed by 6 pediatric oncologists, to identify their referral patterns. The chart review demonstrated that 25 of the 35 patients had reports of musculoskeletal complications sometime during their treatment, but only 10 (30%) were referred to PT. The most common reason for referral was decreased functional mobility. Patients were referred evenly through all phases of therapy. Vincristine was reduced in 5 patients, the most common cause being peripheral neuropathy and foot drop. The majority (5/6) of the physicians reported that they "sometimes" refer patients to PT, through different phases of therapy, with 1/3 reporting all phases. The results show that although physicians identified the musculoskeletal complications, only a minority of patients were referred for PT. This supports the need for increasing the awareness of physicians about benefits of early integration of PT into the medical treatment.

Abstract
Neurologic signs and symptoms are often the initial presenting features of a primary brain tumor and may also emerge during the course of therapy or as late effects of the tumor and its treatment. Variables that influence the development of such neurologic complications include the type, size, and location of the tumor, the patient's age at diagnosis, and the treatment modalities used. Heightened surveillance and improved neuroimaging modalities have been instrumental in detecting and addressing such complications, which are often not appreciated until many years after completion of therapy. As current brain tumor therapies are continually refined and newer targeted therapies are developed, it will be important for future cooperative group studies to include systematic assessments to determine the incidence of neurologic complications and to provide a framework for the development of novel strategies for prevention and intervention.

Abstract
BACKGROUND Although physical activity may modify the late effects of childhood cancer treatment, from 20% to 52% of adult survivors are sedentary. The authors of this report sought to identify modifiable factors that influence survivors' participation in physical activity. METHODS Structural equation modeling of data were derived from the Childhood Cancer Survivors Study of adult survivors (current mean age, 30.98 years; mean years since diagnosis, 23.74; mean age at diagnosis, 9.25 years) who were diagnosed between 1970 and 1986. RESULTS Approximately 40% of the variance in male survivors' recent participation versus nonparticipation in physical activity was explained directly and/or indirectly by self-reported health fears (P = .01), perceived primary-care physician (PCP) expertise (P = .01), baseline exercise frequency (P < or = .001), education level (P = .01), self-reported stamina (P = .01), cancer-related pain (P < or = .001), fatigue (P < or = .001), age at diagnosis (P = .01), cancer-related anxiety (P < or = .001), motivation (P = .01), affect (P = .01), and discussion of subsequent cancer risk with the PCP (P < or = .001) (N = 256; chi-square test statistic = 53.38; degrees of freedom [df] = 51; P = .38, Comparative Fit Index [CFI] = 1.000; Tucker Lewis Index [TLI] = 1.000; root mean square of approximation [RMSEA] = 0.014; weighted root mean square residual [WRMR] = 0.76). Thirty-one percent of the variance in women' recent physical activity participation was explained directly and/or indirectly by self-reported stamina (P < or = .001), fatigue (P = .01), baseline exercise frequency (P = .01), cancer-related pain (P < or = .001), cancer-related anxiety (P = .01), recency of visits with PCP (<0.001), quality of interaction with the PCP (P = .01), and motivation (P < or = .001; N = 366; chi-square test statistic = 67.52; df = 55; P = .12; CFI = 0.98; TLI = 0.98; RMSEA = 0.025; WRMR = 0.76). CONCLUSIONS Gender-tailored intervention strategies in which providers specifically target motivation, fear, and affect may support physical activity in childhood cancer survivors.

Abstract
The neurotoxicity of methotrexate (MTX) is more severe when administered intrathecally (IT) than by the oral and intravenous (IV) routes, and has been reported even with a single administration of therapeutic doses of 12 or 15mg. Prompt recognition and treatment are essential to improve the outcome after massive IT-MTX overdose. Treatment options include CSF drainage or CSF exchange, ventriculolumbar perfusion, IT corticosteroids to reduce CSF inflammation and IV leucovorin to reduce systemic toxicity. Toxicity resulting from IT injection of leucovorin is controversial. CSF drainage and exchange are particularly effective if performed soon after the overdose. In this paper we describe a protocol of treatment for severe cases of IT-MTX overdose in excess of 100mg. The mainstay of treatment is dilution and removal from CSF of excessive methotrexate alongside with specific antidotal therapy.

Abstract
BACKGROUND The purpose of this study was to examine the effects of physical therapy intervention in children with acute lymphoblastic leukemia (ALL). PROCEDURE Twenty-eight children aged 4-15 years were randomly assigned to an intervention or control group. The intervention group received five sessions of physical therapy and was instructed to perform an individualized home exercise program consisting of ankle dorsiflexion stretching, lower extremity strengthening, and aerobic exercise. RESULTS After 4 months children who received physical therapy intervention had significantly improved ankle dorsiflexion active range of motion and knee extension strength (P < 0.01). Differences were not found between the two groups for any of the other dependent variables. CONCLUSIONS Physical therapy intervention for children with ALL receiving maintenance chemotherapy improved two body functions important for normal gait. Physical therapy programs initiated earlier in treatment and with greater emphasis on endurance activities may also improve stamina and quality of life (QOL).

Abstract
Survivors of acute lymphoblastic leukemia (ALL) in childhood have been identified with balance problems. The goals of this study were to objectively quantify these observations by measuring the displacement and velocity of the body centre of pressure, a measure of 'sway'. The subjects included 79 ALL survivors who were at least 1 year post-treatment for ALL and 83 age-matched controls. Testing was carried out using various static balance tests designed to challenge central nervous system maintenance of balance and postural control. Patients were different from controls, across all age groups, in the more difficult task in which they were required to balance over a narrow base of support. However this did not reach statistical significance. When they were asked to perform this task with their eyes closed 32% of the patients tested, as opposed to 2% of controls, were unable to complete the task (significant at P<0.01, chi(2)). The youngest group of patients (children aged 5-7 years) presented consistently with lower (or similar) displacement and lower velocity measures. This phenomenon has been observed in healthy children, however, in patients, these trends were magnified and beyond the normal age range in healthy children. The velocity values were significantly different from the other patient groups (normalized values for velocity; P<0.01). These observations then manifested as higher sway values when patients were challenged with a difficult task with their eyes closed. We propose that survivors of childhood ALL have delayed motor development compared to age-matched controls giving rise to impairment in balance and postural control. It is possible that these impairments are a consequence of intensive multi-agent chemotherapy and cranial irradiation.

Abstract
BACKGROUND Previous research has indicated that children who have received treatment for leukaemia which includes cranial irradiation exhibit deficits in their ability to focus attention. It has been suggested that the use of cranial irradiation may have a role to play in long term sequelae. AIMS To investigate neuropsychological functioning among children treated for leukaemia without cranial irradiation. METHODS In a cross sectional study, 17 leukaemic patients and their sibling controls were assessed using a neuropsychological model of attention. All were treated on the UKALL XI protocol and none had received cranial irradiation. Participants completed the Arithmetic subtest and Digit Span subtest of the Weschler Intelligence Scale for Children-Revised to assess focus-encode elements of attention; the Coding subtest and the Speed of Information subtest of the BAS to assess focus-execute aspects of attention; the VIGIL computerised battery to assess sustain elements of attention; and the Wisconsin Card Sorting test to assess the ability to shift attention. RESULTS These children did not exhibit the deficits witnessed in previous cohorts, and were performing at comparable levels to their controls on all measures of attention CONCLUSIONS These findings suggest that children who have received treatment for leukaemia without the use of cranial irradiation do not show the neuropsychological insult found in earlier treatment groups.

Abstract
BACKGROUND The objective of the current study was to determine whether therapy for childhood acute lymphoblastic leukemia (ALL) results in long-lasting neurologic signs or electrophysiologic injuries within the motor tracts. METHODS Twenty-seven children who were treated for ALL were studied clinically 5 years after the cessation of therapy by means of motor-evoked potentials (MEPs) elicited by magnetic stimulation transcranially and peripherally. An equal number of healthy children matched with regard to age, gender, and height served as the control group. RESULTS The MEP latencies to the hands and legs elicited by stimulation at the cortex were prolonged significantly in the children treated for ALL compared with the control group, with the differences being 2.2 milliseconds [ms] (P < 0.001) from the cortex to the thenar on the right side and 2.0 ms (P < 0.001) on the left, and 1.4 ms (P = 0.004) from the cortex to the leg on the right side and 1.3 ms (P = 0.004) on the left. Correspondingly, the MEP latency from the fifth lumbar vertebrae (LV) level to the leg also was prolonged, by 1.0 ms (P = 0.005) on the right side and 0.8 ms (P = 0.005) on the left side. The calculated latency between the cortex and the LV level was not found to be significantly longer in those patients treated for ALL compared with the healthy controls. Neurologic signs, in the form of depressed deep tendon reflexes, were observed in 8% of the patients, whereas approximately 33% of the patients were found to have fine or gross motor difficulties and dysdiadochokinesia. CONCLUSIONS Neurologic signs still persisted 5 years after therapy for ALL. Approximately 33% of the patients had fine or gross motor difficulties and dysdiadochokinesia, and demyelinative injuries to the peripheral nerve tracts were found proximally but not within the central nervous system.

Abstract
BACKGROUND The objective was to evaluate whether motor nervous pathways are affected when patients are treated for childhood acute lymphoblastic leukemia (ALL). PROCEDURE Thirty-two children with ALL were studied at the end of treatment by means of motor evoked potentials (MEPs) elicited by magnetic stimulation (MS) transcranially and peripherally and underwent a detailed neurological examination. Thirty-two healthy children matched with them for age, sex, and height served as a control group. RESULTS The latencies of the MEPs were significantly prolonged along the entire motor nervous pathway in the patients with ALL compared with the healthy controls, indicating demyelination in the thick motor fibres. The MEP amplitudes of the distal extremities elicited by stimulation at the brachial plexus and LV spinal level were significantly lowered in the patients treated for ALL, also indicating anatomical or functional loss of descending motor fibres and/or muscle fibres. The MEP amplitudes elicited by cortical MS showed wider variation and no clear abnormalities were found. Neurological signs and symptoms were common after treatment: 41% of the patients had depressed deep tendon reflexes, 31% had fine motor difficulties and 63% gross motor difficulties, and 34% had dysdiadochokinesia. The conduction delay within the peripheral nerve was related to the post-therapeutic interval after administration of vincristine and the lesions within the CNS to the number of injections of intrathecal methotrexate. CONCLUSIONS The present results show adverse effects of the ALL treatment on the entire motor nervous pathways. In our experience, the measurement of MEPs by MS provides an objective, painless, and practical tool for assessing the treatment-related neurotoxicity in both the CNS and the peripheral nerves. These disturbances in the motor nervous pathways at the end of treatment raise the question of the long-term effects of ALL treatment on the motor nerve tracts, and have led us to employ MEPs to study these effects in long-term survivors of ALL.

Abstract
Methotrexate can influence the central nervous system through several metabolic toxic pathways. These effects can be categorized as immediate, acute to subacute, or chronic neurologic syndromes. The acute to subacute syndrome occurs frequently in acute lymphoblastic leukemia treatment protocols, generally manifesting with focal neurologic signs and changes seen on magnetic resonance imaging and single photon emission computed tomography. While in some patients the neurotoxicity is transient and benign and allows for continuation of chemotherapy, in others it can be quite severe and debilitating, leading to permanent neurologic deficits. The need to modify the treatment protocols when neurotoxicity appears is not fully established. It is also unknown whether the use of sufficient amounts of leucovorin can overcome the toxic effects of the drug.

Abstract
PURPOSE Cytarabine (ara-C) is one of the most effective chemotherapeutic agents in patients with acute leukemia (AL), with a clear dose effect. Use of high-dose ara-C is hampered, however, by a noticeable toxicity, particularly to the CNS. We investigated the usefulness of CNS perfusion imaging with technetium-99m ((99m)Tc)-hexamethyl-propylene-amine oxime (HMPAO) single-photon emission computed tomography (SPECT) concurrent to magnetic resonance imaging (MRI) to specifically assess the effects of standard- and high-dose ara-C in children with AL. PATIENTS AND METHODS Twenty-six perfusion studies using (99m)Tc-HMPAO SPECT were performed in 12 children (age range, 4 to 15 years) with AL after induction therapy, which consisted of a standard-dose ara-C, immediately after consolidation with high-dose ara-C, and later during follow-up (range, 6 to 44 months). The chemotherapy-related adverse events were monitored and correlated to SPECT and MRI. RESULTS After the induction phase, all children were neurologically normal on MRI. On SPECT imaging, four children displayed a slightly heterogeneous perfusion. After high-dose ara-C (4 to 36 g/m(2)), five children had regressive neurologic signs of potential toxic origin. Of these five children, only one had an abnormal MRI scan, whereas all patients showed evidence of diffuse cerebral and/or cerebellar heterogeneous perfusion on SPECT. The seven other patients without any neurologic symptoms had normal MRI scans; SPECT was normal for three patients and abnormal for four patients. On follow-up, for four children who had presented with clinical neurologic toxicity, SPECT improved in three patients and remained unchanged in one patients. In two of these four children, delayed abnormalities (T2 white matter hypersignal and cerebellar atrophy) appeared on MRI scans. CONCLUSION In our series, diffuse heterogeneous brain hypoperfusion is often the sole early objective imaging feature identified by SPECT of high-dose ara-C neurotoxicity, where MRI still demonstrates normal pictures.

Abstract
BACKGROUND The purpose of this study was to evaluate and determine the factors related to active and passive dorsiflexion range of motion (DF-ROM) in survivors of acute lymphoblastic leukemia (ALL), which is the most obvious impairment of musculoskeletal function in such children. PROCEDURE The subjects included 54 survivors of ALL treated on Dana-Farber Cancer Institute protocols and 54 comparable healthy children. Bilateral active and passive DF-ROM were measured with the knee extended. RESULTS The survivors of ALL had significantly less active and passive DF-ROM (6.4 vs. 16.8, 10.5 vs. 18.8 degrees, respectively, P < 0.001) than the comparison children. Weight for age at the time of assessment and change in height during treatment showed significant negative correlations with DF-ROM. Length of time-off treatment was not associated with DF-ROM. CONCLUSIONS Multiple regression analyses identified the variables of age at diagnosis and gender as significant predictors of both DF-ROM measures following treatment. Children diagnosed at a younger age and females were at greater risk for restricted DF-ROM. Close monitoring and preventative therapy programs for this complication are warranted for children, especially young girls receiving treatment for ALL.
