Clinical Trial Summary

The investigators would like to conduct a prospective, multicenter, two-armed trial (RCT with follow-up). Patients will be recruited from 7 centers (CH/D). All patients (and their guardians) scheduled to receive chemotherapy containing either a platinum derivate or vinca-alkaloid, will be asked to participate. Willing patients will then be randomized either into an intervention group or a control group. Patients in the intervention group will perform a standardized, age-adjusted, specific playful sensorimotor training (SMT) program twice a week for the duration of their medical therapy, in addition to usual care, while the control group receives treatment as usual. The CG will be given the opportunity to participate in the intervention after therapy. Data will be assessed at 3-4 time points: Prior to chemotherapy (baseline T0), after 12 weeks (T1), after completion of therapy for children that are treated >3 months (Tp) and after 12 months follow-up (T3). Additionally, status of Chemotherapy-induced peripheral neuropathy (CIPN) reported symptoms will be monitored twice in-between (6 weeks).

The investigators hypothesize that less children in the intervention group will develop symptoms of CIPN (TNS score) with its debilitating side-effects. Furthermore, children in the intervention group will be able to maintain relevant motor and sensory functions and their associated physical functions which will enable them to receive their planned medical therapy but also to stay on the age-appropriate motor development level, improve their quality life and enhance social reintegration after therapy.

Description:

Modern therapy has improved survival for children with cancer. However, treatment has unintended consequences. Depending on the neurotoxic agent (platinum derivates or vinca-alkaloids), 52%-100% of children develop a peripheral neuropathy. Diagnosis is underreported and its impact as potentially initial cause for many sensory and motor symptoms underestimated. The severe symptoms such as loss of sensation, numbness, pain, absent reflexes as well as loss of balance control not only delays motor development milestones such as walking, running, jumping or climbing, diminishing children's quality of life and affecting their social reintegration, but is also of high clinical relevance. Additionally, recovery is poor and there are currently no effective options to prevent or treat the symptoms of Chemotherapy-induced peripheral neuropathy (CIPN). Promising results have so far been achieved with specific exercise interventions.

The investigators would therefore like to conduct a prospective, multicenter, two-armed trial (RCT with follow-up). Patients N=131 will be recruited from 7 centers: University Children's Hospital of Basel, the Inselspital Bern, Kantonsspital Aarau, Children Hospital for Eastern Switzerland St. Gallen, University Children Hospital Freiburg and the National Center for tumor diseases (NCT), University Children Hospital Heidelberg, Charité Berlin. All patients (and their guardians) scheduled to receive chemotherapy containing either a platinum derivate or vinca-alkaloid, will be asked to participate. Willing patients will then be randomized either into an intervention group or a control group (CG). Patients in the intervention group will perform a standardized, age-adjusted, specific playful sensorimotor training (SMT) program twice a week for the duration of their medical therapy, in addition to usual care, while the control group receives treatment as usual. The CG will be given the opportunity to participate in the intervention after therapy. Data will be assessed at 3-4 time points: Prior to chemotherapy (baseline T0), after 12 weeks (T1), after completion of therapy for children that are treated >3 months (Tp) and after 12 months follow-up (T3). Additionally, status of CIPN reported symptoms will be monitored twice in-between (6 weeks). The investigators hypothesize that less children in the intervention group will develop symptoms of CIPN (TNS score) with its debilitating side-effects. Furthermore, children in the intervention group will be able to maintain relevant motor and sensory functions and their associated physical functions which will enable them to receive their planned medical therapy but also to stay on the age-appropriate motor development level, improve their quality life and enhance social reintegration after therapy.

Intervention

Behavioral:
• Playful sensorimotor training
For the max. duration of the first in-hospital phase (3weeks), all children will receive supervised training. When children go home they will be supplied with a manual, specific exercises and the necessary training devices. Regular supervision will allow to ensure that the training is performed at maximum benefit. Each session will last for about 20 to 30 minutes in total, including a child-specific warm-up and cool-down. The children will be asked to maintain balance in a previously acquired "short-foot-position", knees slightly flexed (30°), without shoes. Training will consist of 5 playful balance exercises chosen from a standardized pool of exercises according to the child's age, with increasing difficulty in order to allow for individual, optimal progression. Each of the 5 exercises will contain of 5 repetitions for 10sec. allowing for a 20sec. rest in between each set and a 1min rest between each exercise in order to avoid neural fatigue.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pre-/Post incidence of neuropathic symptoms via Ped-mTNS score	Primary endpoint is the Ped-mTNS score. It contains a short questionnaire as well as a clinical test battery. The questionnaire is composed of three sets of questions on sensory symptoms and pain, motor function, and autonomic function, and a five- part neurologic exam. The clinical test battery contains light touch sensation, evaluated with Semmes-Weinstein-monofilaments, pin sensibility (MediPin), vibration sensibility assessed with a biothesiometer, deep tendon reflexes of Achilles and patellar tendons and muscular strength examined by a manual muscle test36, each category is rated on a likert scale from 0-4 (0 indicating no symptoms and 4 severe symptoms).
