ABSTRACT
Metronomic chemotherapy-based combinations have received interest for relapsed/refractory malignancies. Preclinical and clinical studies showed activity of metronomic etoposide and axitinib. We report our retrospective experience in six children treated with axitinib and metronomic etoposide for refractory/relapsed brain tumors as an "off-label" combination. Three patients with medulloblastoma experienced partial response; one patient with atypical teratoid rhabdoid tumor (ATRT) displays an ongoing stable disease (12 months); two patients with medulloblastoma had progressive disease. Grade 3-4 toxicities were observed in two patients (thrombocytopenia, anemia, diarrhea, fatigue). The axitinib-etoposide combination shows signals of efficacy in heavily pretreated patients with relapsed/refractory brain tumors. These results were based on real-world observation and will need formal evaluation in a phase I/II trial.

BACKGROUND: The need for new therapies to improve survival and outcomes in pediatric oncology along with the lack of approval and accessible clinical trials has led to "out-of-trial" use of innovative therapies. We conducted a retrospective analysis of requests for innovative anticancer therapy in Canadian pediatric oncology tertiary centers for patients less than 30 years old between 2013 and 2020. METHODS: Innovative therapies were defined as cancer-directed drugs used (a) off-label, (b) unlicensed drugs being used outside the context of a clinical trial, or (c) approved drugs with limited evidence in pediatrics. We excluded cytotoxic chemotherapy, cellular products, and cytokines. RESULTS: We retrieved data on 352 innovative therapy drug requests. Underlying diagnosis was primary CNS tumor 31%; extracranial solid tumor 37%, leukemia/lymphoma 22%, LCH 2%, and plexiform neurofibroma 6%. RAS/MAP kinase pathway inhibitors were the most frequently requested innovative therapies in 28% of all requests followed by multi-targeted tyrosine kinase inhibitors (17%), inhibitors of the PIK3CA-mTOR-AKT pathway (8%), immune checkpoints inhibitors (8%), and antibody drug conjugates (8%). In 112 out of 352 requests, innovative therapies were used in combination with another anticancer agent. 48% of requests were motivated by the presence of an actionable molecular target. Compassionate access accounted for 52% of all requests while public insurance was used in 27%. Mechanisms of funding varied between provinces. CONCLUSION: This real-world data collection illustrates an increasing use of "out-of-trial" innovative therapies in pediatric oncology. This new field of practice warrants further studies to understand the impact on patient trajectory and equity in access to innovative therapies.

Objectives: To evaluate physicians' opinions concerning continuous deep sedation until death (CDSUD) and implementation of Claeys-Leonetti; a law intended to be applicable to all patients, but without a specific framework for children thus giving rise to ethically and legally complex situations. The secondary objective was to identify if physicians' characteristics could influence their opinions. Study Design: This was a national, multicenter, noninterventional cross-sectional survey from January 30, 2020, until March 1, 2020. The target population consisted of French physicians involved in children's end-of-life situations. The validated questionnaire explored respondents' characteristics and their opinions on four hypothetical pediatric clinical cases. Results: Analysis was conducted on 391 respondents. The oncological situation was more easily recognized as end of life compared with the neurological pathology (77% vs. 40.4%). Dependence on mechanical ventilation was another major factor influencing physicians in identifying end-of-life situations. Physicians clearly recognized the difference in intention between CDSUD and euthanasia. They accepted to implement CDSUD more easily in newborns. The withdrawal of artificial nutrition and hydration gave rise to divergent opinions. Respondents were in favor of adolescents' decision-making autonomy and their access to drafting advance directives. The child's best interest prevailed in case of objection by parents, except in situations outside the law's framework or in cases of disagreement within the health care team. Conclusion: Results of our study showed differences in the interpretation of the law concerning the CDSUD application framework and provide elements for reflection, which may ultimately contribute to the development of specific guidelines in CDSUD in children at the end of life.

Solid tumors or predisposition syndromes are increasingly suspected before birth. However optimal management and outcomes remain unclear. We have performed a ten-year retrospective study of oncologic indications of prenatal diagnosis in public hospitals in Marseille. Data were obtained from prenatal diagnosis center and hospital imaging databases and pediatric oncology department files. Fifty-one cases were identified, 40 with mass: adrenal 17, sacrococcygeal 9, cardiac 7, abdominal 4, ovarian 1, cervical 2; 8 with developmental abnormalities (omphalocele 4, macroglossia 4), 3 WITH familial predisposition syndromes (familial rhabdoid 2, Li-Fraumeni 1). Median detection time was 30 week. Termination of pregnancy was decided for 9 fetuses (4 cardiac lesions and suspected tuberous sclerosis, 2 sacrococcygeal tumors, 1 Beckwith-Wiedemann Syndrome, 2 SMARCB1 mutations. Preterm birth occurred in 8 cases. Eleven newborns (26,1%) required intensive care (8 for mechanical complications). Of of 17 adrenal mass ES, 4 disappeared before birth and 5 before one year. Seventeen newborns underwent surgery: 13 masses (teratoma 7, myelomeningocele 2, cystic nephroma 1, neuroblastoma 2), 4 omphaloceles, one biopsy. Surgery performed after one year for incomplete regression identified 1 neuroblastoma, 2 bronchogenic cysts and 2 nonmalignant masses. Three newborns received chemotherapy. Except one patient with BWS who died of obstructive apnea, all children are alive disease free with a median follow-up of 60 months [9-131 months]. Twelve have sequelae. Various solid tumors and cancer predisposition syndromes can be detected before birth. A multidisciplinary collaboration is strongly recommended for optimal management before and after birth.

Innovative therapeutic approaches are needed to alleviate the burden of life-limiting, rare, and chronic conditions affecting children, adolescents, and young adults (CAYA). This includes a need for improved access to both clinical research and to non-approved or off-label therapies, together with, ultimately, more therapies achieving regulatory approval in Canada. The single patient study (SPS), also known as an open label individual patient (OLIP) study, was introduced by Health Canada to open access to non-marketed drugs where a clinical trial is not readily available, but the drug is considered too investigational to be managed on a standard Special Access Program. SPS is designed for patients who have a serious or life-threatening condition and have exhausted available treatment options. Our report summarizes this relatively new development in the Canadian regulatory environment and highlights the opportunities and challenges as identified by regulators, pharmaceutical representatives, academic researchers, and patient/parent advocates.
ABSTRACT
(1) Background: Children and young adults with cancer are poorly represented in COVID-19 vaccination studies, and long-term protection conferred by vaccination is not known. (2) Objectives: 1. To determine the adverse effects associated with BNT162B2 vaccination in children and young adults with cancer. 2. To assess its efficacy in stimulating immunological response and in preventing severe COVID-19 disease. (3) Methods: Retrospective single-center study evaluating patients aged 8 to 22 years, with cancer, who underwent vaccination from January 2021 to June 2022. ELISA serologies and serum neutralization were collected monthly from the first injection. Serologies below 26 were considered negative, while those above 264 BAU/mL were considered positive and indicative of protection. Antibodies titers were considered positive above 20. Data on adverse events and infections were collected. (4) Results: 38 patients were included (M/F = 1.7, median age 16 years), of whom 63% had a localized tumor and 76% were undergoing treatment at the time of the first vaccination. Two or three vaccine injections were administered in 90% of patients. Adverse events were mainly systemic and not severe, except for seven grade 3 toxicities. Four cancer-related deaths were reported. Median serology was negative the month following the first vaccination and became protective during the third month. At 3 and 12 months, median serology was 1778 and 6437 BAU/mL, respectively. Serum neutralization was positive in 97% of the patients. COVID-19 infection occurred despite vaccination in 18%; all were mild forms. (5) Conclusions: In children and young adults with cancer, vaccination was well tolerated and conferred effective serum neutralization. COVID-19 infections were mild, and vaccine seroconversion persisted after 12 months in most patients. The value of additional vaccination should be further established.
ABSTRACT
OBJECTIVE: Childhood and adolescent cancer can result in high burden of distressing symptoms, particularly in high-risk malignancies. The Symptom Screening in Pediatrics Tool (SSPedi) is a reliable and valid approach to measure bothersome symptoms in paediatric patients receiving cancer treatments. Objective was to describe the feasibility of using SSPedi administration among paediatric patients with high-risk malignancies. METHODS: We conducted a single-centre, cross-sectional study of patients aged 8-18 years with high-risk malignancies in a French paediatric oncology unit. Patients self-reported the degree of bothersome symptoms using SSPedi and difficulty with SSPedi completion. The total SSPedi Score ranging from 0 to 60 (where 60 is worst) and most common moderately bothersome symptoms (scored ≥2 on 0-4 Likert Scale) were described. Feasibility was defined as more than 75% of patients agreeing to participate and more than 90% completion of SSPedi questionnaire. RESULTS: Out of 16 patients approached, 1 declined participation. Median age was 13 years (IQR 8-19). All were able to self-report SSPedi without difficulty. Patients experienced a median number of 6 (range 0-15) bothersome symptoms (score >0). The mean total SSPedi Score was 12 (SD=9.4). Most common moderately bothersome symptoms were pain (8/15), changes in hunger (8/15) and feeling tired (7/15). CONCLUSION: Patient-reported symptom assessment among children and adolescents with high-risk malignancies is feasible using SSPedi. These patients experience a high burden of bothersome symptoms.

Precision oncology requires tumor molecular profiling to identify actionable targets. Tumor biopsies are considered as the gold standard, but their indications are limited by the burden of procedures in children. Blood-derived liquid biopsy (LB) is a potential alternative that is not yet documented in real-world settings, especially in pediatric oncology. We performed a retrospective analysis of children and teenagers with a relapsing or refractory disease, upon whom LB was performed using the Foundation One® liquid CDx from 1 January 2020 to 31 December 2021 in a single center. Forty-five patients (27 boys) were included, with a median age of 9 years of age (range: 1.5-17 years old). Underlying malignancies were neuroblastoma (12 patients), bone sarcoma (12), soft tissue sarcoma (9), brain tumors (7), and miscellaneous tumors (5). Forty-three patients had metastatic disease. Six patients had more than one biopsy because of a failure in first LB. Median time to obtain results was 13 days. Overall, analysis was successful for 33/45 patients. Eight patients did not present any molecular abnormalities. Molecular alterations were identified in 25 samples with a mean of 2.1 alterations per sample. The most common alterations concerned TP53 (7 pts), EWS-FLI1 (5), ALK (3), MYC (3), and CREBBP (2). TMB was low in all cases. Six patients received treatment based on the results from LB analysis and all were treated off-trial. Three additional patients were included in early phase clinical trials. Mean duration of treatment was 85 days, with one patient with stable disease after eight months. Molecular profiling using Foundation One® Liquid CDx was feasible in pediatric patients with high-risk solid tumors and lead to identification of targetable mutations in a subset of patients.
ABSTRACT
BACKGROUND AND AIMS: COVID-19 infection in paediatric patients with cancer is severe or critical in 20% of the patients. It can therefore directly affect paediatric patients with cancer and/or their care. We aimed at evaluating the safety and efficacy of the BNT162b2 mRNA COVID-19 vaccine in adolescents and young adults (AYA) with solid tumour. METHODS: This study includes a retrospective analysis of safety and efficacy of the BNT162b2 mRNA COVID-19 vaccine administered to patients, ≥16 years old, under treatment for a solid tumour or within 6 months after treatment from 15th February 2021 to 15th April 2021. Two administrations of the vaccine 3 weeks apart were given. Sera were tested for anti-SARS-Cov-2 immunoglobulin G (IgG) antibodies directed against the S1 domain of the spike protein. In case of positive serology, neutralisation of SARS-Cov-2 was tested. RESULTS: Twenty-three patients with solid tumours were identified and proposed to get vaccinated. Nine patients refused, and 1 previously developed COVID-19 infection with positive serology. At the time of writing, 13 patients (10 M/2 F; median age: 17) started vaccination. All patients received 2 injections except 2 patients who stopped vaccination because of tumour progression. Ten patients were under treatment (alone or in combination: chemotherapy: 7 patients [pts], immunotherapy: 2 pts, targeted therapy: 3 pts, follow-up: 3 patients). Overall, vaccines were well tolerated. Five patients did not report any side-effects after the first injection and 4 after the second injection. The main local reactivity symptom was mild pain at the site of injection (6 and 2 pts). Fatigue (2 pts and 5 pts) was the most frequent systemic symptom. One patient refused serology testing. All patients but 1 had pre-vaccination negative serology; 7 of 10 patients tested had positive serology before second vaccine injection, and 9 of 10 patients had positive serology one month after the second injection. All patients with seroconversion had positive COVID-19 neutralisation test. No patient developed COVID infections. CONCLUSIONS: We report the good safety profile and good efficacy of the BNT162B2 vaccine in AYA with solid tumours. Larger series and monitoring of the kinetics of anti-Sars-Cov-2 IgG antibodies for several months are mandatory to confirm these preliminary results and to determine long-term vaccination.

PURPOSE: To update the 2015 clinical practice guideline for the prevention of oral mucositis in pediatric cancer or hematopoietic stem cell transplant (HSCT) patients. METHODS: We performed seven systematic reviews of mucositis prevention. Three reviews included randomized controlled trials (RCTs) conducted in pediatric and adult patients evaluating cryotherapy, keratinocyte growth factor (KGF) or photobiomodulation therapy with a focus on efficacy. Three reviews included studies of any design conducted in pediatric patients evaluating these same interventions with a focus on adverse events and feasibility. One review included all RCTs of any intervention for mucositis prevention in pediatric patients. Primary outcome was severe oral mucositis. RESULTS: We included 107 unique studies of cryotherapy (22 RCTs and 4 pediatric studies); KGF (15 RCTs and 12 pediatric studies); photobiomodulation therapy (29 RCTs and 8 pediatric studies) and any intervention (31 pediatric RCTs). Effects on severe mucositis reduction from RCTs were cryotherapy risk ratio (RR) 0.49 and 95% confidence interval (CI) 0.31-0.76; palifermin RR 0.81 and 95% CI 0.69-0.95 and photobiomodulation therapy RR 0.40 and 95% CI 0.27-0.60. Cryotherapy was not feasible in young children while photobiomodulation therapy was feasible across age groups. Palifermin was associated with adverse effects. CONCLUSIONS: Cryotherapy should be used for older cooperative pediatric patients who will receive short infusions of melphalan or 5-fluorouracil. Intraoral photobiomodulation therapy (620-750 nm spectrum) should be used in pediatric patients undergoing autologous or allogeneic HSCT and for pediatric head and neck carcinoma patients undergoing radiotherapy. Palifermin should not be used routinely in pediatric cancer or HSCT patients.

There is a growing interest in physical activity (PA) in paediatric oncology. Overall studies in children with cancer have reported good adherence, positive trends in health status, and no adverse events. Thus, a general PA program should be offered to paediatric oncology inpatients. Anyhow, the absence of a dedicated place to perform PA sessions beyond the paediatric oncology department corridors and patients' room has been identified as one of the major limiting factors. We do believe "in the ward" sport rooms should be further implemented and evaluated in paediatric oncology departments worldwide.

BACKGROUND: to evaluate the safety and efficacy of a physical activity program (PAP) in children and adolescents with cancer. METHODS: children and adolescents with cancer were randomly assigned in a 1:1 ratio to the six-month PAP (intervention group) or to the control group. The first evaluation was performed at the end of the PAP (T0 + 6 mo). At T0 + 6 mo, both groups received the six-month PAP with a second evaluation at T0 + 12 mo. The primary outcome was the evolution of exercise capacity measured using the six-minute walk test (6 MWT) at T0 + 6 mo. Secondary outcomes included PAP safety and changes in other physical functions, self-esteem, and quality-of-life parameters. RESULTS: The trial involved 80 children and adolescents (age range 5.0-18.4 years), of whom 41 were assigned to the interventional group and 39 to the control group. Underlying malignancies were leukemia (39%) and a broad range of solid tumors (61%). No adverse events occurred. At T0 + 6 mo, the evolution of the 6 MWT distance (±SEM) was improved in the intervention group vs. the control group (86 ± 12 m vs. 32 ± 6 m, p < 0.001). Several other physical parameters were significantly improved in the intervention group. Global self-esteem and parent-reported quality-of-life were significantly increased in the intervention group. Analysis at T0 + 12 mo showed persistence of the benefits in the intervention group on exercise capacity evolution (115 ± 18 m vs. 49 ± 11 m, p = 0.004) and on most physical and QoL parameters. CONCLUSION: In children and adolescents with cancer, a physical activity program is safe, improves exercise capacity, and may have physical and psychological benefits.
ABSTRACT
BACKGROUND: Pediatric low-grade glioma (pLGG) represents the most common brain tumor in childhood. Previous studies have reported that a therapeutic strategy on the basis of the association of bevacizumab alone (B) or in combination with irinotecan (BI) could produce rapid tumor response and clinical improvement in children with pLGG. Nevertheless, a majority of patients relapses shortly (median, 5 mo) after stopping B or BI treatment. We proposed metronomic maintenance with weekly vinblastine added after a 6 months induction of B/BI to prevent early relapse. PATIENTS AND METHODS: Monocentric retrospective analysis of a patient with pLGG treated with B or BI for 6 months followed by a 12-month maintenance with weekly vinblastine (6 mg/m²) from October 2012 to September 2019 in a single institution. RESULTS: In total, 18 patients (7 males and 11 females) were identified. Because of progression during the B or BI induction 2/18 children were excluded. In total, 16 patients were analyzed with a median age of 10 years (range, 4 to 16 y). A total of 13 patients received BI and 3 patients received B alone. The mean duration of induction was 6.2 months (range, 2 to 12 mo). After induction 5/16 patients had a partial radiologic response, 11/16 patients had stable disease. All patients started maintenance (median duration, 12 mo; range, 3 to 12 mo). With a median follow-up of 3.9 years after the end of B or BI (range, 11 mo to 7.2 y), 15/16 patients were alive and 9/16 patients were progression-free. Seven of 16 children progressed with a median time to progression of 23 months (ranges, 5 to 39 mo). Three of 16 (18%) children progressed during vinblastine maintenance and 4/16 (25%) patients after the end of maintenance. After the total duration of treatment, clinical improvement was noted in 4 patients, 9 patients had stable symptoms, and only 3 patients progressed. One and 2-year event-free survival were, respectively, 81.2% and 56.2%. Two-year overall survival was 93.7%. CONCLUSIONS: We report here, the potential benefit and the improvement of progression-free survival by adding metronomic maintenance with weekly vinblastine after initial induction with B or BI in children with low-grade glioma.

OBJECTIVES: Symptom Screening in Pediatrics Tool (SSPedi) is a validated approach to measuring bothersome symptoms for English-speaking and Spanish-speaking children with cancer and paediatric haematopoietic stem cell transplantation (HSCT) recipients. Objectives were to translate SSPedi into French, and among French-speaking children receiving cancer treatments, to evaluate understandability and cultural relevance. METHODS: We conducted a multiphase, descriptive study to translate SSPedi into French. Forward translation was performed by four medical translators. After confirming that back translation was satisfactory, we enrolled French-speaking children with cancer and paediatric HSCT recipients at four centres in France and Canada. PRIMARY AND SECONDARY OUTCOME MEASURES: Understandability was evaluated by children themselves who self-reported degree of difficulty, and by two adjudicators who rated incorrectness. Assessment of cultural relevance was qualitative. Participants were enrolled in cohorts of 10. RESULTS: There were 30 children enrolled. Participants were enrolled from Marseille (n=10, 33%), Ottawa (n=1, 3%), Quebec City (n=11, 37%) and Toronto (n=8, 27%). No child reported that it was hard or very hard to complete French SSPedi in the last cohort of 10 participants. Changes to the instrument itself were not required. After enrolment of 30 respondents, the French translation of SSPedi was considered finalised based on self-reported difficulty with understanding, adjudicated incorrect understanding and cultural relevance. CONCLUSIONS: We translated and finalised SSPedi for use by French-speaking children and adolescents receiving cancer treatments. Future work should begin to use the translated version to conduct research and to facilitate clinical care.

PURPOSE: Low- and middle-income countries (LMICs) experience the burden of 80% of new childhood cancer cases worldwide, with cure rates as low as 10% in some countries. Metronomics combines frequent administrations of low-dose chemotherapy with drug repurposing, which consists of using already-approved drugs for new medical applications. With wide availability, limited costs, and little infrastructure needs, metronomics can be part of constraint-adapted regimens in these resource-limited settings-with the understanding that metronomics shall not be a substitute for standard treatments when available and doable. Our study aims to describe the experience, practices, opinions, and needs in metronomics of physicians working in LMICs. METHODS: An online questionnaire was sent to more than 1,200 physicians in pediatric oncology networks in LMICs. Items included the type of center, physician's demographics, experience in pediatric oncology, and experience with current knowledge of metronomics. Opinions and perspectives were explored using multiple-answer and open questions. RESULTS: Of physicians, 17% responded. Of respondents, 54.9% declared that they had already used a metronomic regimen. The most frequently cited repositioned drugs were celecoxib (44%) followed by propranolol and valproic acid (17%). Respondents highlighted the advantages of outpatient use (20%) and expected low toxicity (24%). In considering the drawbacks of metronomics, 47% of responses highlighted the lack of scientific evidence or guidelines, 33% the availability or affordability of drugs, and 18% the problem of acceptance or compliance. Of physicians, 79% believed that use of metronomics will spread in LMICs in the near future and 98% of them were willing to participate in international metronomic protocols or registries. CONCLUSION: Metronomics is already used in LMICs and is a potential answer to unmet needs in pediatric oncology. There is room for improvement in the availability of drugs and a necessity to develop collaborative protocols and research to generate level A evidence.

BACKGROUND: Efforts to improve the quality of end-of-life (EOL) care depend on better knowledge of the care that children, adolescents, and young adults with cancer receive, including high-intensity EOL (HI-EOL) care. The objective was to assess the rates of HI-EOL care in this population and to determine patient- and hospital-related predictors of HI-EOL from the French national hospital database. METHODS: This was a population-based, retrospective study of a cohort of patients aged 0 to 25 years at the time of death who died at hospital as a result of cancer in France between 2014 and 2016. The primary outcome was HI-EOL care, defined as the occurrence of ≥1 chemotherapy session <14 days from death, receiving care in an intensive care unit ≥1 time, >1 emergency room admission, and >1 hospitalization in an acute care unit in the last 30 days of life. RESULTS: The study included 1899 individuals from 345 hospitals; 61.4% experienced HI-EOL care. HI-EOL was increased with social disadvantage (adjusted odds ratio [AOR], 1.30; 95% confidence interval [CI], 1.03-1.65; P = .028), hematological malignancies (AOR, 2.09; 95% CI, 1.57-2.77; P < .001), complex chronic conditions (AOR, 1.60; 95% CI, 1.23-2.09; P = .001) and care delivered in a specialty center (AOR, 1.70; 95% CI, 1.22-2.36; P = .001). HI-EOL was reduced in cases of palliative care (AOR, 0.31; 95% CI, 0.24-0.41; P < .001). CONCLUSION: A majority of children, adolescents, and young adults experience HI-EOL care. Several features (eg, social disadvantage, cancer diagnosis, complex chronic conditions, and specialty center care) were associated with HI-EOL care. These findings should now be discussed with patients, families, and professionals to define the optimal EOL.
