  • Return to sports after pediatric brain tumors: time to move beyond survival

    by William Zardo, Olga Nigro, Veronica Biassoni, Elisabetta Schiavello, Marta Podda, Monica Terenziani, Maura Massimino, Filippo Spreafico

    Brain tumors are the second most common malignancy in children and adolescents and the leading cause of cancer-related death in this population. While survival rates have improved, survivors are at risk of neurocognitive, motor, and psychosocial sequelae due to both tumor location and treatments used. Participation in sport is increasingly recognized as beneficial for functional recovery, cardiorespiratory fitness, and overall well-being in children and adolescents treated for brain tumors. However, return to play (RTP) may pose some challenges, particularly in the presence of neurosurgical devices, cranial radiotherapy, or residual neurological deficits. This narrative clinical review summarizes current evidence on the risks of sport-related injuries in pediatric brain tumor patients and survivors, highlighting factors influencing vulnerability, including treatment history and specific sport characteristics. We propose a risk-based framework for RTP evaluation emphasizing individualized coordinated assessment by pediatric oncologists, neurosurgeons, and sports medicine specialists. Protective strategies are discussed, although evidence for concussion prevention remains limited. A safe RTP should be enhanced by the here-proposed structured evaluation, balancing safety with the physical, cognitive, and psychosocial benefits of active participation. This framework aims to support clinicians and families in facilitating safe and effective reintegration of pediatric brain tumor survivors into both recreational and competitive sports.

    The Impact of a Precision-Based Exercise Intervention in Childhood Hematological Malignancies Evaluated by an Adapted Yo-Yo Intermittent Recovery Test

    During cancer treatments in childhood hematological malignancies, reduced exercise tolerance is one of the main hardships. Precision-based training programs help children, adolescents, and young adults and their families to resume regular physical activity, exercise, and sports once they return to their communities after the intensive phases spent in hospital. This study was aimed at verifying whether an intermittent recovery test, the Yo-Yo AD, could provide a simple and valid way to evaluate an individual’s capacity to perform repeated intense exercise and to follow up on the impact of tailored exercise in children, adolescents, and young adults with hematological malignancies. The Yo-Yo AD involved the repetition of several shuttles to muscle exhaustion, at pre-established speeds (walking and slow running). The heart rate (HR) and oxygen saturation (SaO2) were monitored during the test. The total distance and the walking/running ability, measured as the slope of the HR vs. distance correlation, were investigated before (T0) and after 11 weeks (T1) of precision exercise intervention. The Yo-Yo AD was also performed by healthy children (CTRL). Ninety-seven patients (10.58 ± 4.5 years, 46% female) were enrolled. The Yo-Yo AD showed the positive impact of the exercise intervention by increasing the distance covered by the individuals (T0 = 946.6 ± 438.2 vs. T1 = 1352.3 ± 600.6 m, p < 0.001) with a more efficient walking/running ability (T0 = 2.17 ± 0.84 vs. T1 = 1.73 ± 0.89 slope, p < 0.0164). CTRLs performed better (1754.0 ± 444.0 m, p = 0.010). They were equally skillful (1.71 ± 0.27 slope) when compared to the patients after they received the precision-based intervention. No adverse events occurred during the Yo-Yo AD and it proved to be an accurate way of correctly depicting the changes in performance in childhood hematological malignancies.

    Osteopathic Treatment and Evaluation in the Clinical Setting of Childhood Hematological Malignancies

    Children: adolescents, and young who are adults affected with hematological malignancies (CAYA-H) and who are undergoing intensive phases of cancer treatment, including hematopoietic stem cell transplantation (HSCT), experience diminished functional ability. This study was aimed at assessing the feasibility, efficacy, safety, and satisfaction of an osteopathic intervention in CAYA-H attending an 11-week precision-based exercise program (PEx). All of the participants were given 4–10 treatments according to the prescription ordered by the sports medicine doctor in charge of the PEx, and the following outcomes were assessed: (1) spinal column range of motion (ROM) by palpation; (2) lower and upper limb joints ROM by a goniometer; (3) orthostatic posture by plumb line assessment; (4) chest and abdomen mobility by inspection and palpation; (5) cranial-sacral rhythmic impulse (CRI) by palpation; and (6) adverse effects. Goal attainment scaling (GAS) was used to identify the accomplishment of a desired clinical result. Moreover, HSCT patients who were affected with graft-versus-host disease and/or osteonecrosis had their joints assessed in terms of ROM as tools to monitor the effectiveness of immunosuppressive treatment. A total of 231 CAYA-H were identified, and 104 participated in the study (age 10.66 ± 4.51 yrs; 43% F). PEx plus osteopathy reached positive GAS scores by improving the ROMs of the spinal column and/or limbs (81% and 78%, respectively), chest and abdomen mobility (82%), and CRI (76%). Only minor reversible adverse effects were noticed during the study. Together, our data seem to initiate a new course where osteopathy could be useful in evaluating structural edges due to the clinical history of each CAYA-H. Given the contributions that were obtained by the GAS scores, osteopathic treatment seems to reveal interesting potential that can be targeted in the future.
