ABSTRACT
PURPOSE: Growth failure is common in radiotherapy-treated long-term survivors of pediatric brain tumors, but studies on longitudinal growth in this patient group are lacking. Here, the aim was to assess the changes in growth patterns before and after brain tumor diagnosis, the adult height, and the risk factors for compromised growth. The incidence and treatment practices of growth hormone deficiency were analyzed. METHODS: A cohort of 73 survivors of childhood brain tumor (median age 27.2 years, range 16.2 to 43.8 years) was studied after a median follow-up period of 20.4 years from diagnosis (IQR 14.9 to 22.9 years). Patients were treated in five university hospitals in Finland between 1970 and 2008. Growth curves, final height, and patient- and disease-related risk factors for compromised growth during different growth periods were analyzed. Laboratory analyses for IGF-1 and IGFBP-3 were performed at the follow-up. RESULTS: Growth failure was evident at diagnosis, with a mean height decline of -0.6 SDS (standard deviation score) from birth (95% CI -1.15 to -0.05). Mean height SDS decline after the diagnosis was -1.09 SDS (95%CI -1.51 to -0.66). At follow-up, 37% of the study subjects (27/73) had true short stature (height < -2 SDS). The mean height deficit corrected for target height was -1.9 SDS (95% CI -1.45 to -2.40). Growth failure was associated with the age at diagnosis, corticosteroid dose, radiotherapy modality and mean dose of irradiation in the thalamic area. Low IGF-1 level (below -2.0 SDS) was found in 32% (23/72), and untreated growth hormone deficiency in 40% (29/72) of the subjects. CONCLUSION: Longitudinal growth impairment was common in radiotherapy-treated survivors of childhood brain tumor, resulting in compromised adult height. Loss of growth potential was evident already at diagnosis and further accelerated by the treatments. At young adulthood, unrecognized growth hormone deficiency was common.

BACKGROUND: Little is known of the cognitive functions, employment, and social status in adult survivors of childhood brain tumor (BT). We aimed to determine the long-term neurocognitive profile of radiotherapy-treated adult survivors of childhood BT and the relationship between cognitive functions and employment and social status. METHODS: Neurocognitive profiles of survivors were assessed in a Finnish national cohort of 71 radiotherapy-treated survivors of childhood BT (median follow-up time: 21 years [range: 5-33 years]) using a cross-sectional design. Neurocognitive outcomes were compared to control (n = 45) and normative values. Tumor- and treatment-related data were collected from the patient files. Information on employment and social status was gathered. RESULTS: Survivors' (median age: 27 years [range: 16-43 years]) median verbal and performance intelligence quotient (IQ) was 90 (range: 49-121) and 87 (range: 43-119), respectively. The cognitive domains with the greatest impairment were executive functions (median z score, -3.5 SD [range: -25.0 to 1.3 SD]), and processing speed and attention (median z score, -2.5 SD [range: -24.9 to 0.5 SD]). Executive functions were associated with employment, educational level, living independently, having an intimate relationship, and having a driving license. Processing speed and attention were related to educational level, living independently, having an intimate relationship, and having a driving license. Performance IQ was associated with educational level and employment status. Working memory was associated with educational level and living independently. CONCLUSIONS: Radiotherapy-treated adult survivors of childhood BT experience significant neurocognitive impairment, which is associated with difficulties related to employment and social status.
ABSTRACT
Children with cancer are dealing with different side and long-term effects caused by cancer and its treatments, like vinca-alkaloids, which may have negative effects on motor performance. However, the affected areas of motor performance (aiming and catching, balance, manual dexterity) and the differences in these areas between boys and girls and diagnoses are not frequently reported in a longitudinal design. Therefore, the aim of this study was to investigate how motor performance changes over the course of cancer treatment. The study was conducted with 3-to 16-year-old children with cancer (N = 36) in 2013-2017. The five assessment points were 0, 2, 6, 12 and 30 months from diagnosis. Movement-ABC2 was used to assess motor performance. We found that aiming and catching skills decreased significantly during the follow-up (p < 0.05). Balance was affected at the 2-month measurement point (p < 0.05) and more in children with acute lymphoblastic leukemia than in children with other cancer diagnoses (p < 0.05). Girls performed better than boys in manual dexterity at 6, 12 and 30 months (p < 0.05, p < 0.05, p < 0.05, respectively). Individual monitoring of motor performance with standardized tests and physical activity/exercise programs during and after treatment are needed.
ABSTRACT
BACKGROUND: Cranial radiotherapy may damage the cerebral vasculature. The aim of this study was to understand the prevalence and risk factors of cerebrovascular disease (CVD) and white matter hyperintensities (WMHs) in childhood brain tumors (CBT) survivors treated with radiotherapy. METHODS: Seventy CBT survivors who received radiotherapy were enrolled in a cross-sectional study at a median 20 years after radiotherapy cessation. The prevalence of and risk factors for CVD were investigated using MRI, MRA, and laboratory testing. Tumors, their treatment, and stroke-related data were retrieved from patients' files. RESULTS: Forty-four individuals (63%) had CVD at a median age of 27 years (range, 16-43 years). The prevalence rates at 20 years for CVD, small-vessel disease, and large-vessel disease were 52%, 38%, and 16%, respectively. Ischemic infarcts were diagnosed in 6 survivors, and cerebral hemorrhage in 2. Lacunar infarcts were present in 7, periventricular or deep WMHs in 34 (49%), and mineralizing microangiopathy in 21 (30%) survivors. Multiple pathologies were detected in 44% of the participants, and most lesions were located in a high-dose radiation area. Higher blood pressure was associated with CVD and a presence of WMHs. Higher cholesterol levels increased the risk of ischemic infarcts and WMHs, and lower levels of high-density lipoprotein and higher waist circumference increased the risk of lacunar infarcts. CONCLUSIONS: Treating CBTs with radiotherapy increases the risk of early CVD and WMHs in young adult survivors. These results suggest an urgent need for investigating CVD prevention in CBT patients.
ABSTRACT
BACKGROUND: Children with central nervous system (CNS) toxicity during therapy for acute lymphoblastic leukaemia (ALL) are at risk for treatment modifications, long-term sequelae and even higher mortality. A better understanding of CNS symptoms and their complications improves the potential to prevent and treat them. METHODS: Patient files from 649 children treated with Nordic Society of Pediatric Hematology and Oncology ALL92 and ALL2000 protocols in Finland were reviewed retrospectively for any acute CNS symptom. Detailed data on symptoms, examinations and treatment of the underlying CNS complications were collected from the medical records. Disease-related and outcome data were retrieved from the Nordic leukaemia registry. RESULTS: Altogether, 13% (86) of patients with ALL had acute CNS symptoms. Most symptoms (64%) occurred during the first 2 months of therapy. Posterior reversible encephalopathy syndrome was the most frequent complication (4.5%). Cerebrovascular events were diagnosed in 10 cases (1.6%), while methotrexate-related stroke-like syndrome (SLS) was observed in only one patient (0.2%). CNS symptoms due to systemic or unclear conditions, especially sepsis, were important for differential diagnosis. CNS leukaemia was associated with CNS symptoms (hazard ratio [HR] = 4.03; P = .003), and epilepsy was a common sequel of CNS complications (19%). CONCLUSIONS: Acute CNS symptoms are common during ALL therapy, occurring mainly during the first 2 months of treatment. Patients with CNS leukaemia at diagnosis are at a higher risk for CNS toxicity. Despite intensive CNS-directed methotrexate treatment, SLS was diagnosed extremely rarely in our series.

OBJECTIVE: To evaluate the effect of active video games in promoting physical activity and motor performance, and reducing fatigue in children with cancer. A randomized controlled trial was conducted. The intervention included playing Nintendo Wii™Fit (Nintendo Co., Ltd., Kyoto, Japan) for 30 min/day for 8 weeks. Physical activity was estimated with accelerometers, physical activity diaries and questionnaires. Movement-ABC2 and PedsQL™ were used to examine motor performance and fatigue. Intervention experiences and fidelity were examined with an interview. RESULTS: Participants (n = 36 children with cancer, 3-16 years-old) were randomly assigned to the intervention and control groups. The median [min-max] accelerometer counts/h (500 [131-1130] vs 385 [116-1012], p = 0.63) and physical activity min/day (34 [0-150] vs 23 [0-260], p = 0.95) did not differ between the groups. Change between the pre-test and post-test regarding motor performance and fatigue was similar in both groups (motor performance p = 0.77; fatigue p = 1.00). Participants experienced playing active video games meaningful, but the intervention was not followed completely as instructed. Overall, the physical activity levels were low and one fourth of the children had or were at risk of having movement difficulties. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01748058 (October 15, 2012).

Purpose: Childhood brain tumors (CBTs) and their treatment increase the risk of secondary neoplasms (SNs). We studied the incidence of secondary craniospinal tumors with magnetic resonance imaging (MRI) screening in a national cohort of survivors of CBT treated with radiotherapy, and we analyzed the Finnish Cancer Registry (FCR) data on SNs in survivors of CBT with radiotherapy registered as a part of the primary tumor treatment. Methods: A total of 73 survivors of CBT participated in the MRI study (mean follow-up of 19 ± 6.2 years). The incidence of SNs in a cohort of CBT patients (N = 569) was retrieved from the FCR (mean follow-up of 11 ± 12.9 years). Brain tumors were diagnosed at age ≤16 years between the years 1970 and 2008 in the clinical study and the years 1963 and 2010 in the FCR population. Results: Secondary brain tumors, meningiomas in all and schwannoma in one, were found in 6 of the 73 (8.2%) survivors with a mean of 23 ± 4.3 years after the diagnosis of the primary tumor. The cumulative incidence was 10.2% (95% confidence interval [CI] 3.9-25.1) in 25 years of follow-up. In the FCR data, the 25-year cumulative incidence of SNs was 2.4% (95% CI 1.3-4.1); only two brain tumors, no meningiomas, were registered. Conclusion: Survivors of CBT treated with radiotherapy have a high incidence of meningiomas, which are rarely registered in the FCR.

PURPOSE: Long-term side effects of the treatments are common in survivors of irradiated pediatric brain tumors. Ionizing radiation in combination with surgery and chemotherapy during childhood may reduce vertebral height and bone mineral density (BMD), and cause growth failure. The aim of this study was to evaluate the late consequences of tumor treatments on vertebrae in survivors of childhood brain tumors. METHODS: 72 adult survivors (mean age 27.8 years, standard deviation 6.7) of irradiated childhood brain tumor were studied by spinal magnetic resonance imaging (MRI) for vertebral abnormalities from the national cohort of Finland. Patients were treated in five university hospitals in Finland between the years 1970 and 2008. Subject height and weight were measured and body mass index (BMI) was calculated. The morphology and height/depth ratio of the vertebrae in the middle of the kyphotic thoracic curvature (Th8) and lumbar lordosis (L3) were examined. Vertebrae were analyzed by Genant's semiquantative (SQ) method and spinal deformity index (SDI) was calculated. BMD was measured by using dual X-ray absorptiometry. RESULTS: 4.2% (3/72) of the patients had undiagnosed asymptomatic vertebral fracture and 5.6% (4/72) of patients had radiation-induced decreased vertebral body height. Male patients had flatter vertebrae compared with females. Patient age at the time of irradiation, BMI and irradiation area correlated to vertebral morphology differentially in males and females. BMD had no association with the vertebral shape. Patients who had received craniospinal irradiation were shorter than the general population. CONCLUSION: Childhood brain tumor survivors had a high number of vertebral abnormalities in young adulthood. Irradiation was associated with abnormal vertebral morphology and compromised final height. Male gender may predispose vertebrae to the side effects of irradiation.

INTRODUCTION: The increase in the number of childhood brain tumor survivors warrants detailed research to increase our knowledge regarding the possible physical and psychosocial adverse outcomes of tumor and tumor therapy. The aim of this study was to evaluate the current bone health by measuring the bone mineral density (BMD) in irradiated, adult long-term survivors of childhood brain tumors. MATERIAL AND METHODS: We studied a national cohort of 74 adult survivors of childhood brain tumors treated with irradiation in Finland between 1970 and 2008. Dual X-ray absorptiometry (DXA) was performed for the femoral necks, total hips, and lumbar spine. Laboratory tests were conducted for evaluating the pituitary, thyroid, and gonadal functions. The participants were interviewed, examined clinically, and the disease and treatment related data were retrieved from the patient files. RESULTS: One fourth of the patients (23.6%) had sex- and age-normalized z-scores below the expected range for age (z-score ≤ -2.0). Mean BMD scores were decreased in all the DXA measurement sites. Male sex was associated with low BMD (p < .05), while body mass index (BMI) had a significant positive association with BMD (p < .01). Mode of irradiation (with or without spinal irradiation) or inclusion of chemotherapy in the treatment did not affect BMD significantly. However, patients with a ventriculoperitoneal shunt had lower BMD than those without a shunt (p < .05). Follicle stimulating hormone (FSH) and luteinizing hormone (LH) were negatively associated with BMD in women (p < .05). However, a higher cumulative dose of glucocorticoids during treatment was not associated with lower BMD, while low BMD was significantly associated with previous fractures in long bones. DISCUSSION: Low BMD should be taken in consideration in treatment of irradiated childhood brain tumor survivors especially in those with previous fractures in long bones.

Posterior reversible encephalopathy syndrome (PRES) in children with acute lymphoblastic leukemia has been increasingly recognized as a clinicoradiological entity. Our aim was to describe the incidence of PRES in pediatric patients with ALL, identify its risk factors, and examine its prognostic importance. For this research, we conducted a systematic, retrospective review of the patient records in a population-based series of children with acute lymphoblastic leukemia (n=643) treated in Finland from 1992 to 2008. Of the patients with ALL, 4.5% (n=29) developed radiologically confirmed PRES, of which 28 cases occurred during induction. Hypertension (P=0.006; odds ratio [OR], 4.10, confidence interval [CI], 1.50-11.25), constipation (P=0.001; OR, 5.60; CI, 2.02-15.52), and >14 days of alkalinization (P=0.017; OR, 3.27; CI, 1.23-8.68) were significant independent risk factors for PRES. One-third of the patients developed epilepsy. Relapses occurred significantly more often in those patients with PRES (P=0.001), which was associated with worse overall survival (P=0.040; 5-year survival=75.9% [60.3%-91.4%] vs. 88.4% [85.8%-90.9%]). Using NOPHO-ALL 92/2000 protocols, PRES is a significant early complication of therapy in ALL, and was associated with a poorer prognosis and significant neurological morbidity.

Humoral and cellular immunity were studied in 28 children completing conventional treatment of standard-risk (SR) or intermediate-risk (IR) acute lymphoblastic leukemia (ALL). Both naïve and memory B cells were most severely affected and showed slow recovery during the 2-year follow-up, while the T-cell compartment showed only minor changes. Immunoglobulins and IgG subclasses, components, and antibodies against vaccine-preventable diseases were not significantly affected. In conclusion, immune recovery after conventional chemotherapy for SR and IR ALL is marked by B-cell depletion, but otherwise did not show any severe deficiencies in lymphocyte function.

BACKGROUND: Advanced echocardiographic methods may reveal signs of late anthracycline cardiac toxicity (ACT) even in asymptomatic patients. We studied echocardiographic tissue Doppler imaging (TDI) and velocity vector imaging (VVI) in long-term survivors of childhood acute lymphoblastic leukemia (ALL) before and after an exercise intervention. METHODS: Twenty-one asymptomatic, anthracycline-treated, long-term childhood ALL survivors with matched controls were studied at baseline. Seventeen of the survivors participated in a 3-month home-based exercise program. Echocardiography with TDI and VVI was performed. RESULTS: At baseline, ejection fraction (60.7 ± 4.7% vs. 62.3 ± 3.7%, P = 0.22) and fractional shortening (32.6 ± 3.1% vs. 34.0 ± 2.8%, P = 0.13) were similar in survivors and controls. Lateral early diastolic mitral annulus velocity E' (32.81 ± 5.71 cm/sec vs. 38.03 ± 6.21 cm/sec, P = 0.01), E'/A' (1.60 ± 0.48 vs. 2.07 ± 0.63, P = 0.01), and E/E' (2.78 ± 0.35 vs. 2.42 ± 0.62, P = 0.04) were impaired compared to controls. Peak circumferential strain and strain rate were attenuated at apex (-24.50 ± 3.46% vs. -28.06 ± 4.39%, P = 0.01 and -1.47 ± 0.22 sec(-1) vs. -1.68 ± 0.33 sec(-1) , P = 0.02) compared to controls. After the intervention, early diastolic mitral inflow velocity E (87.76 ± 12.54 cm/s vs. 95.28 ± 10.48 cm/s, P = 0.04) and E' increased (31.78 ± 5.50 cm/s vs. 34.96 ± 5.41 cm/s, P < 0.01). Peak circumferential systolic and diastolic strain rates at mid-level (-1.22 ± 0.21 sec(-1) vs. -1.35 ± 0.24 sec(-1) , P = 0.04 and 1.25 ± 0.25 sec(-1) vs. 1.48 ± 0.35 sec(-1) , P < 0.01) improved after the exercise program. CONCLUSIONS: A simple home-based exercise program improved cardiac function in asymptomatic childhood ALL survivors. Adding TDI in routine echocardiographic examination may improve the recognition of early signs of ACT, and VVI may bring additional information. The improvements in cardiac function after the exercise program emphasize the importance of physical activity in this population.

The burden of late-effects for young onset brain tumor (BT) survivors needs more careful evaluation. Our aim was to assess the need for endocrinological and neurological medication among this specific group. We identified 5-year survivors diagnosed at the age of 0-24 years between 1988 and 2004 from the Finnish Cancer Registry (N = 602). Data on endocrinological and neurological drug purchases were collected from the Social Insurance Institution of Finland. Five years after diagnosis the most commonly purchased drugs had been: antiepileptics (44.8 %), systemic hydrocortisone (18.3 %), female sex hormones (17.6 %), thyroid hormones (11.2 %), and growth hormone (10.0 %). The survivors showed an increased hazard ratio (HR) for a need for new types of drugs still 5 years after diagnosis. Thyroid hormones (HR 10.6, 95 % CI 5.1-21.4), estrogens (HR 8.0, 95 % CI 2.1-25.7), and antiepileptics (HR 6.3, 95 % CI 3.4-11.2) were bought with high frequencies. Irradiation increased the hazard for drug-purchases other than antiepileptics. Cumulative incidence of purchases of estrogens or androgens increased still 15 years after diagnosis. The cumulative incidence of purchasing thyroid hormones and antiepileptics showed continuous increase for the youngest group, whereas survivors diagnosed at 15-24 years of age reached stable level before 15 years from diagnosis. The need for new medication continued more than a decade after BT diagnosis. Especially the need for new thyroid or sex hormone medication among childhood BT survivors may emerge long after diagnosis.

BACKGROUND: Reports on the quality of life (QOL) of childhood brain tumor (BT) survivors have been inconsistent. As cognitive limitations may restrict their participation in questionnaire-based studies, our aim was to evaluate in depth the QOL with a mixed-method analysis. METHODS: The 5-year survivors of childhood BTs born in 1975-2000 and alive in 2010 were identified via the Finnish Cancer Registry and treating clinics. Twenty-one survivors (32%) participated in a mixed-method analysis including 15D (a general health-related QOL questionnaire), the Beck Depression Inventory, and a qualitative semi-structured interview. RESULTS: Based on the 15D-questionnaire, the BT survivors had an impaired health-related QOL in several dimensions such as speech and usual activities. On the other hand, no difference was found in other dimensions such as distress or vitality. A majority (95%) of the survivors showed no increased risk for depression. The qualitative interview revealed that the most important aspects affecting the QOL of the survivors were positive mental growth, negative conceptions concerning illness, living one day at a time, age at diagnosis, time since diagnosis, social relationships, learning disabilities and limitations in vocational opportunities, limitations in independent life, and changed understanding of the term 'health'. CONCLUSIONS: Childhood BT survivors have heterogeneous attitudes on QOL. The survivors assess social aspects to be more important than functionality for their QOL. Social concerns should actively be brought up to offer support for those with significant social difficulties. Interventions for social difficulties should be more actively developed.

BACKGROUND: Brain tumors (BTs) in adolescence and young adulthood (AYA) differ from those in childhood or late adulthood. However, research concerning late effects in this particular survivor group is limited. This study evaluates late morbidity of survivors diagnosed in AYAs. METHODS: We identified from the Finnish Cancer Registry all survivors diagnosed with BT at the ages 16-24 years between 1970 and 2004 (N = 315) and used data from the Hospital Discharge Registry to evaluate their late (≥5 y after diagnosis) morbidity requiring treatment in a specialized health care setting. A sibling cohort of BT patients diagnosed before the age of 25 years was used as a comparison cohort (N = 3615). RESULTS: The AYA BT survivors had an increased risk for late-appearing endocrine diseases (HR, 2.9; 95% CI, 1.1-8.0), psychiatric disorders (HR, 2.0; 95% CI, 1.2-3.2), diseases of the nervous system (HR, 9; 95% CI, 6.6-14.0), disorders of vision/hearing loss (HR, 3.6; 95% CI, 1.5-8.5), diseases of the circulatory system (HR, 4.9; 95% CI, 2.9-8.1), and diseases of the kidney (HR, 5.9; 95% CI, 2.5-14.1). Survivors with irradiation had an increased risk for diseases of the nervous system compared with non-irradiated survivors (HR, 3.3; 95% CI, 1.8-6.2). The cumulative prevalence for most of the diagnoses remained significantly increased for survivors even 20 years after cancer diagnosis. CONCLUSIONS: The AYA BT survivors have an increased risk of morbidity for multiple new outcomes for ≥5 years after their primary diagnosis. This emphasizes the need for structured late-effect follow-up for this patient group.

BACKGROUND: The population of long-term survivors of childhood brain tumors (BTs) is growing. The aim of our study was to evaluate late-appearing morbidity in BT survivors. METHODS: Patients diagnosed with a BT at the age of 0-15 years between 1970 and 2004, and surviving at least 5 years, were identified from the Finnish Cancer Registry (n = 740). Their late new morbidity ≥ 5 years after cancer diagnosis was assessed using the Hospital Discharge Registry containing hospitalizations and outpatient visits in specialized health care settings. The morbidity of BT survivors was compared with that of the sibling cohort (n = 3615). RESULTS: The 5-year survivors had a significantly increased hazard ratio (HR) for endocrine diseases (HR, 14.7), psychiatric disorders (HR, 1.8), cognitive and developmental disorders (HR, 16.6), neurological diseases (HR, 9.8), disorders of vision and hearing (HR, 10.5), and diseases of the circulatory system (HR, 2.7) compared with the sibling cohort. The HRs for disorders of musculoskeletal system (HR, 1.4) and diseases of the kidney (HR, 2.1) were not significantly increased. Radiation treatment did not explain all of the excess morbidity. Female survivors had a higher risk for disorders of vision and hearing (P = .046). Age at diagnosis did not show an effect on HRs. The HRs for endocrine diseases and disorders of vision or hearing loss were highest for survivors treated in the 1980s or later. CONCLUSIONS: Pediatric BT survivors had significant neurocognitive consequences. This, together with the considerable risk for endocrine morbidity, will motivate us to organize systematic follow-up procedures for pediatric BT survivors.

To date, only few studies have been published documenting late mortality among early onset cancer survivors, especially regarding young adulthood (YA) malignancies. Our nation-wide population-based registry study provides information concerning cause-specific long-term mortality among 16,769 5-year survivors of early onset cancer (aged 0-34 years at diagnosis), with follow-up for death extending from 1971 through 2012. A sibling cohort and population data were used as reference. The overall standardized mortality ratio (SMR) of cancer patients was 4.6-fold, (95% CI 4.4-4.8). Highest SMRs were found for malignancies (12.8, 95% CI 12.3-13.3), infectious (4.8, 95%CI 2.9-6.7) and cardiovascular diseases (1.9, 95% CI 1.7-2.1). Malignancies and cardiovascular diseases accounted for the largest number of deaths. Childhood and YA cancer survivors with the same primary cancer site had a similarly elevated overall SMR with the exception of markedly higher SMRs after childhood Hodgkin lymphoma. The highest cumulative non-malignancy-related mortality was due to cardiovascular disease with a steady rise throughout the follow-up, but strongly dependent on the primary cancer site and age at diagnosis. In childhood cancer survivors, the cumulative cardiovascular mortality did not reduce over time. However, overall and malignancy-related mortality showed a declining tendency towards the most recent periods after both, childhood and YA cancer. Our findings on non-malignancy-related mortality stress the need to set up long-term individual follow-up with a focus on cardiovascular late effects for early onset cancer survivors, especially for YA cancer survivors still lacking those.

BACKGROUND: Despite major treatment attempts, the prognosis for pediatric diffuse intrinsic pontine gliomas (DIPGs) remains dismal. Gliomas are highly vascularized tumors, suggesting that the prevention of vessel formation by anti-angiogenic treatment might be effective. PROCEDURE: Forty-one pediatric patients with DIPG were treated according to the Angiocomb protocol, starting with radiotherapy combined with topotecan and followed by anti-angiogenic triple medication consisting of thalidomide, etoposide, and celecoxib. Overall survival, radiological response, quality of life, requirement of corticosteroids, and adverse effects were monitored. Eight patients treated with only radiotherapy were used as controls. RESULTS: For study patients, the 12 and 24 months overall survival was 61% and 17%, respectively. The median overall survival was 12 months (range 4-60 months). Four radiological complete responses were seen, of which two were transient. Radiologically, 56% of the tumors reduced in size and 78% in signal intensity. Study patients were able to visit school or daycare and walk for a significantly longer time compared to controls (Log Rank 0.036 and 0.008, respectively). Adverse effects were generally minor. CONCLUSIONS: The Angiocomb protocol created a noticeable share of long-term survivors and was well tolerated, suggesting that anti-angiogenic therapy for patients with DIPG should be studied more in the future.

BACKGROUND: Low levels of physical activity, musculoskeletal morbidity and weight gain are commonly reported problems in children with cancer. Intensive medical treatment and a decline in physical activity may also result in reduced motor performance. Therefore, simple and inexpensive ways to promote physical activity and exercise are becoming an increasingly important part of children's cancer treatment. METHODS: The aim of this study is to evaluate the effect of active video games in promotion of physical activity in children with cancer. The research is conducted as a parallel randomized clinical trial with follow-up. Patients between 3 and 16 years old, diagnosed with cancer and treated with vincristine in two specialized medical centers are asked to participate. Based on statistical estimates, the target enrollment is 40 patients. The intervention includes playing elective active video games and, in addition, education and consultations for the family. The control group will receive a general recommendation for physical activity for 30 minutes per day. The main outcomes are the amount of physical activity and sedentary behavior. Other outcomes include motor performance, fatigue and metabolic risk factors. The outcomes are examined with questionnaires, diaries, physical examinations and blood tests at baseline and at 2, 6, 12 and 30 months after the baseline. Additionally, the children's perceptions of the most enjoyable activation methods are explored through an interview at 2 months. DISCUSSION: This trial will help to answer the question of whether playing active video games is beneficial for children with cancer. It will also provide further reasoning for physical activity promotion and training of motor skills during treatment. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT01748058 (October 15, 2012).
