Peripheral neuropathy in survivors of childhood acute lymphoblastic leukemia
Journal of the Peripheral Nervous System, 2009
Acute lymphoblastic leukemia (ALL) is the most common form of cancer in children. Recent advances in treatment have led to dramatically improved survival rates. Standard ALL treatment includes multiple administrations of the chemotherapeutic drug vincristine, which is a known neurotoxic agent. Although peripheral neuropathy is a wellknown toxicity among children receiving vincristine acutely, the long-term effects on the peripheral nervous system in these children are not clear. The objective of this study was to determine the prevalence of neuropathy and its impact on motor function and quality of life (QOL) among children who survived ALL. Thirty-seven survivors of childhood ALL aged 8-18 underwent evaluation for neuropathy through self-reported symptoms, standardized examinations, and nerve conduction studies (NCS). Functional impact of neuropathy was assessed using the Bruininks-Oseretsky test of Motor Proficiency (BOT-2). QOL was assessed using the PedsQL. Nerve conduction study abnormalities were seen in 29.7% of children who were longer than 2 years off therapy for ALL. Most children with an abnormal examination or NCS did not have subjective symptoms. Although overall motor function was below population norms on the BOT-2, presence of neuropathy did not significantly correlate with motor functional status or QOL.

BACKGROUNDThe 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.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.METHODSTwenty-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.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.RESULTSThe 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.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.

Mild axonal neuropathy of children during treatment for acute lymphoblastic leukaemia
European Journal …, 2000
Neurophysiological functioning was studied prospectively in children treated for acute lymphoblastic leukaemia with a low dose vincristine regime (861.5 mg/m 2 /dose), to obtain more insight into vincristine neuropathy. A WHO neurotoxicity score was estimated and vibration sense and electrophysiological measurements were taken at standardized times during vincristine treatment. The WHO neurotoxicity score showed decreased or disappearance of Achilles tendon reflexes, and mild sensory disturbances, but a grade 3±4 neurotoxicity was not demonstrated by any of the children. Vibration perception thresholds increased progressively during treatment and amplitudes of action potentials of peroneal and sensory ulnar and median nerves decreased, whereas nerve conduction velocities stayed unchanged. Both vibration perception thresholds and the electrophysiological findings hardly exceeded the limits of normality. We conclude that children treated for acute lymphoblastic leukaemia with a low dose vincristine regimen have mild axonal neuropathy which may be responsible for the motor problems in these children.
A review of movement disorders in chemotherapy-induced neurotoxicity
Journal of NeuroEngineering and Rehabilitation, 2021
Chemotherapy agents used in the standard treatments for many types of cancer are neurotoxic and can lead to lasting sensory and motor symptoms that compromise day-to-day movement functions in cancer survivors. To date, the details of movement disorders associated with chemotherapy are known largely through self-reported symptoms and functional limitations. There are few quantitative studies of specific movement deficits, limiting our understanding of dysfunction, as well as effective assessments and interventions. The aim of this narrative review is to consolidate the current understanding of sensorimotor disabilities based on quantitative measures in cancer survivors who received chemotherapy. We performed literature searches on PubMed and found 32 relevant movement studies. We categorized these studies into three themes based on the movement deficits investigated: (1) balance and postural control; (2) gait function; (3) upper limb function. This literature suggests that cancer sur...
Risk Factors of Vincristine-Induced Peripheral Neuropathy in Acute Lymphoblastic Leukaemia Children
The Journal of Medical Investigation, 2021
Objective : This study analysed Vincristine-induced peripheral neuropathy (VIPN) risk factors in Acute Lymphoblastic Leukaemia (ALL) children. Method : This cross-sectional study design was performed at Dr. Soetomo Hospital, Surabaya, Indonesia, from August to October 2019. It included ALL children, aged 4-18 years, undergoing the 2013 or 2018 ALL Indonesian Protocol of Chemotherapy, with a cumulative vincristine dose ≥ 12 mg / m 2. VIPN diagnosis is based on complaints, the Total Neuropathy Score Pediatric Vincristine (TNS-PV), and nerve conduction studies (NCS). The examined risk factors were sex, age, ALL classification, nutritional status, impaired liver function, and cumulative vincristine dose. Results : There were 52 ALL children : median age 7 years, 59.6% boys, 59.6% ALL standard risk, 44.2% experienced impaired liver function at initial ALL diagnosis. Based on a single parameter for diagnosis, 26.9% had VIPN based on complaints, 76.9% had it based on the TNS-PV, and 100% had it based on NCS. VIPN was diagnosed in 25% of children, with predominantly motor impairment and located in lower extremities. Impaired liver function is a risk factor for VIPN in ALL children (p = 0.046, prevalence ratio (PR) 2.84). Conclusion : Impaired liver function is a significant risk factor for VIPN in ALL children.
Measuring Vincristine-Induced Peripheral Neuropathy in Children With Acute Lymphoblastic Leukemia
Cancer Nursing, 2013
Background: Vincristine-induced peripheral neuropathy (VIPN) is difficult to quantify in children. Objective: The study objective was to examine the reliability, validity, and clinical feasibility of several VIPN measures for use in children with acute lymphoblastic leukemia. Interventions/Methods: Children (n = 65) aged 1 to 18 years receiving vincristine at 4 academic centers participated in the study. Baseline and preYvincristine administration VIPN assessments were obtained using the Total Neuropathy ScoreYPediatric Vincristine (TNSB-PV), the National Cancer Institute Common Terminology Criteria for Adverse Events, the Balis grading scale, and the FACES Pain Scale. The TNS-PV scores (n = 806) were obtained over 15 weeks. Blood was obtained at several time points to quantify pharmacokinetic parameters. Results: Cronbach's ! for a reduced TNS-PV scale was .84. The TNS-PV scores correlated with cumulative vincristine dosage (r = 0.53, P = 0.01), pharmacokinetic parameters (r = 0.41, P = 0.05), and grading scale scores (r range = 0.46Y0.52, P = .01). FACES scores correlated with the TNS-PV neuropathic pain item (r = 0.48; P = .01) and were attainable in all ages. A 2-item V-Rex score (vibration and reflex items) was the most responsive to change (effect size = 0.65, P G 0.001). The TNS-PV scores were attainable in 95% of children 6 years or older. Conclusions: The TNS-PV is reliable and valid for measuring Measuring
The effect of peripheral neuropathy on daily life activities in patients receiving chemotherapy
Clinical Nursing Studies, 2020
Objective: The aim of this study is to determine the relationship between pain and pain related factors associated with peripheral neuropathy and daily life activities in patients receiving chemotherapy.Methods: The study used a descriptive and cross-sectional design to examine 80 patients who came to the outpatient chemotherapy unit of two university hospitals to receive chemotherapy drugs such as taxane, platinum analogs and vinca alkaloids. The data were collected by using face-to-face interview method through “General Information Form”, “S-LANSS Pain Scale” that is a bedside test for distinctive diagnosis of neuropathic pain and “Health Assessment Questionnaire (HAQ)” which is a scale prepared by the researcher and measures daily activities to evaluate physical disability.Results: In the group with neuropathic pain, HAQ scores (p = .003; p < .01) and S-LANSS scores (p = .005; p < .01) of the patients who did not have hand-foot complaints prior to the treatment but experien...

Vincristine, a critical component of combination chemotherapy treatment for pediatric acute lymphoblastic leukemia (ALL), can lead to vincristine-induced peripheral neuropathy (VIPN). Longitudinal VIPN assessments were obtained over 12 months from newly diagnosed children with ALL (N = 128) aged 1-18 years who received vincristine at one of four academic children's hospitals. VIPN assessments were obtained using the Total Neuropathy Score-Pediatric Vincristine (TNS©-PV), National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE©), Balis© grading scale, and Pediatric Neuropathic Pain Scale©-Five (PNPS©-5). Of children who provided a full TNS©-PV score, 85/109 (78%) developed VIPN (TNS©-PV ≥4). Mean TNS©-PV, grading scale, and pain scores were low. CTCAE©-derived grades 3 and 4 sensory and motor VIPN occurred in 1.6%/0%, and 1.9%/0% of subjects, respectively. VIPN did not resolve in months 8-12 despite decreasing dose density. VIPN was worse in older children. Partition cluster analysis revealed 2-3 patient clusters; one cluster (n = 14) experienced severe VIPN. In this population, VIPN occurs more commonly than previous research suggests, persists throughout the first year of treatment, and can be severe.
Peripheral Neuropathy, Sensory Processing, and Balance in Survivors of Acute Lymphoblastic Leukemia
Journal of clinical oncology : official journal of the American Society of Clinical Oncology, 2018
Purpose To compare peripheral nervous system function and balance between adult survivors of childhood acute lymphoblastic leukemia (ALL) and matched controls and to determine associations between peripheral neuropathy (PN) and limitations in static balance, mobility, walking endurance, and quality of life (QoL) among survivors. Patients and Methods Three hundred sixty-five adult survivors of childhood ALL and 365 controls with no cancer history completed assessments of PN (modified Total Neuropathy Score [mTNS]), static balance (Sensory Organization Test [SOT]), mobility (Timed Up and Go), walking endurance (6-minute walk test), QoL (Medical Outcomes Study 36-Item Short Form Survey), and visual-motor processing speed (Wechsler Adult Intelligence Scale). Results PN, but not impairments, in performance on SOT was more common in survivors than controls (41.4% v 9.5%, respectively; P < .001). In multivariable models, higher mTNS scores were associated with longer time to complete th...
