RESUMO
Introduction: Mediport use as a clinical option for the administration of chimeric antigen receptor T cell (CAR T cell) therapy in patients with B-cell malignancies has yet to be standardized. Concern for mediport dislodgement, cell infiltration, and ineffective therapy delivery to systemic circulation has resulted in variable practice with intravenous administration of CAR T cell therapy. With CAR T cell commercialization, it is important to establish practice standards for CAR T cell delivery. We conducted a study to establish usage patterns of mediports in the clinical setting and provide a standard of care recommendation for mediport use as an acceptable form of access for CAR T cell infusions. Methods: In this retrospective cohort study, data on mediport use and infiltration rate was collected from a survey across 34 medical centers in the Pediatric Real-World CAR Consortium, capturing 504 CAR T cell infusion routes across 489 patients. Data represents the largest, and to our knowledge sole, report on clinical CAR T cell infusion practice patterns since FDA approval and CAR T cell commercialization in 2017. Results: Across 34 sites, all reported tunneled central venous catheters, including Broviac® and Hickman® catheters, as accepted standard venous options for CAR T cell infusion. Use of mediports as a standard clinical practice was reported in 29 of 34 sites (85%). Of 489 evaluable patients with reported route of CAR T cell infusion, 184 patients were infused using mediports, with no reported incidences of CAR T cell infiltration. Discussion/Conclusion: Based on current clinical practice, mediports are a commonly utilized form of access for CAR T cell therapy administration. These findings support the safe practice of mediport usage as an accepted standard line option for CAR T cell infusion.

BACKGROUNDCurrently, no laboratory tests exist to stratify for the risk of developing sinusoidal obstruction syndrome (SOS), an early endothelial complication after hematopoietic cell transplantation (HCT). Risk biomarkers of SOS have not been verified in a prospective cohort accounting for differences between practices across institutions. Herein, we aimed to define risk groups for SOS occurrence using 3 proteins: L-ficolin, hyaluronic acid (HA), and stimulation 2 (ST2). METHODSBetween 2017 and 2021, we prospectively accrued 80 pediatric patients across 4 US centers. Biomarkers were tested by ELISA blind to patient groupings and associated with SOS incidence on day 35 after HCT, and overall survival (OS) on day 100 after HCT. Cutpoints were identified using retrospective cohorts and applied to the prospective cohort.RESULTSCombination of the 3 biomarkers measured on day 3 after HCT in the prospective cohort provided 80% (95% CI 55%-100%) sensitivity and 73% (95% CI 62%-83%) specificity for risk of SOS occurrence. Patients with low L-ficolin were 9 times (95% CI 3-32) more likely to develop SOS, while patients with high HA and ST2 were 6.5 (95% CI 1.9-22.0) and 5.5 (95% CI 2.3-13.1) times more likely to develop SOS. These 3 markers also predicted worse day 100 OS - L-ficolin: HR, 10.0 (95% CI 2.2-45.1), P = 0.0002; HA: HR, 4.1 (95% CI 1.0-16.4), P = 0.031; and ST2: HR, 3.9 (95% CI 0.9-16.4), P = 0.04.CONCLUSIONL-ficolin, HA, and ST2 levels measured as early as 3 days after HCT improved risk stratification for SOS occurrence and OS and may guide risk-adapted preemptive therapy.TRIAL REGISTRATIONClinicalTrials.gov NCT03132337.FUNDINGNIH.

OBJECTIVES: To describe the prevalence of multiple organ dysfunction syndrome (MODS) and critical care utilization in children and young adults with acute myeloid leukemia (AML) who have not undergone hematopoietic cell transplantation (HCT). DESIGN: Retrospective cohort study of MODS (defined as dysfunction of two or more organ systems) occurring any day within the first 72 hours of PICU admission. SETTING: Large, quaternary-care children's hospital. PATIENTS: Patients 1 month through 26 years old who were treated for AML from 2011-2019. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Eighty patients with AML were included. These 80 patients had a total of 409 total non-HCT-related hospital and 71 PICU admissions. The majority 53 of 71 of PICU admissions (75%) were associated with MODS within the first 72 hours. MODS was present in 49 of 71 of PICU admissions (69%) on day 1, 29 of 52 (56%) on day 2, and 25 of 32 (78%) on day 3. The organ systems most often involved were hematologic, respiratory, and cardiovascular. There was an increasing proportion of renal failure (8/71 [11%] on day 1 to 8/32 [25%] on day 3; p = 0.02) and respiratory failure (33/71 [47%] to 24/32 [75%]; p = 0.001) as PICU stay progressed. The presence of MODS on day 1 was associated with a longer PICU length of stay (LOS) (ß = 5.4 [95% CI, 0.7-10.2]; p = 0.024) and over a six-fold increased risk of an LOS over 2 days (odds ratio, 6.08 [95% CI, 1.59-23.23]; p = 0.008). Respiratory failure on admission was associated with higher risk of increased LOS. CONCLUSIONS: AML patients frequently require intensive care. In this cohort, MODS occurred in over half of PICU admissions and was associated with longer PICU LOS. Respiratory failure was associated with the development of MODS and progressive MODS, as well as prolonged LOS.

INTRODUCTION: Western Kenya is home to approximately 24 million people, with 10 million children under the age of 15 years.1 Based on estimates of cancer incidence in similar populations from around the world, approximately 1500 patients should be diagnosed with pediatric cancer each year. This article describes the international collaboration that investigates potential barriers preventing the effective diagnosis of pediatric patients with cancer. METHODS: Here, we describe a multidisciplinary and sequential approach to better evaluate the complex factors affecting the lack of appropriate diagnosis of pediatric cancer in Western Kenya. RESULTS: Internal review at a large tertiary hospital noted 200-250 patients were diagnosed annually, suggesting the remaining 75%-80% of patients go undiagnosed and do not receive treatment. Following our screening process at a local referring hospital, 41 malaria slides demonstrated both morphologic and genetic evidence of leukemia. Knowledge assessments of local providers at referring institutions suggested a lack of education and training as the factors that contribute to lower rates of diagnosis. DISCUSSION: Through a multi-step approach, our teams were better able to isolate potential issues impeding the appropriate and timely diagnosis of pediatric cancer in Kenya.

Chimeric antigen receptor T-cell (CAR-T) Cell Therapy is approved for the treatment of pediatric patients with relapsed/refractory acute lymphoblastic leukemia B-ALL. Lentiviral vector technology, highly modified from HIV-1, is used to induce stable, long-term transgene expression by integration into the host genome. This integration may interfere with HIV-1 NAAT producing false-positive results. Guidance for HIV diagnostic testing in pediatric B-ALL undergoing this type of therapy is lacking. Herein, we report case series with presented scenarios in which HIV-1 NAAT testing among CAR-T cell patients produced false-positive results, highlighting the importance careful assay selection and performance among this patient population.

Granulocyte colony-stimulating factor (G-CSF) used after hematopoietic stem cell transplantation (HSCT) can enhance neutrophil recovery in patients rendered neutropenic by the preparative regimen. G-CSF is contraindicated in patients with sickle cell disease (SCD), because life-threatening complications can ensue in the presence of sickle vasculopathy. The safety profile of G-CSF after HSCT for SCD has not been described, however. We report clinical outcomes in the first 100 days post-HSCT in 62 patients supported with G-CSF until neutrophil recovery on a clinical trial of reduced- intensity conditioning HSCT for SCD. The patients received G-CSF for a median of 9 days (range, 5 to 33 days) post-transplantation from the best available stem cell source. Preparation for transplantation included a target hemoglobin S level of ≤45%. Neutrophil engraftment (absolute neutrophil count >0.5 × 103/mL) was achieved at a median of 13 days (range, 10 to 34 days), and platelet engraftment (>50 × 103/mL) was achieved at a median of 19 days (range, 12 to 71 days). The median duration of inpatient hospitalization following stem cell infusion (day 0) was 21.5 days (range, 11 to 33 days). No patient developed SCD-related complications following G-CSF use. The most common organ toxicities encountered between G-CSF initiation (on day +7) and day +100 were anorexia (n = 14), hypertension (n = 11), and electrolyte imbalance requiring correction (n = 9). Central nervous system-related events were noted in 5 patients, all of whom had preexisting cerebral vasculopathy/moyamoya disease, attributed to reversible posterior leukoencephalopathy syndrome in the presence of calcineurin inhibitor therapy and hypertension. We conclude that G-CSF does not adversely impact SCD HSCT recipients and can be safely used post-transplantation to enhance neutrophil recovery.

The etiology and outcomes of posterior reversible encephalopathy syndrome (PRES) in children with cancer are not well understood. We aim to determine the incidence of PRES, describe associated morbidity and mortality, and better understand risk factors in this patient population. A total of 473 children with a hematologic malignancy or postallogeneic hematopoietic cell transplantation between June 2015 and June 2020 were screened for PRES to determine incidence and whether age or underlying diagnosis are associated with development of PRES. We conducted a case-control study to evaluate whether comorbidities or chemotherapeutic agents are associated with PRES. Children with PRES were matched with 2 controls based on age and underlying diagnosis to identify additional risk factors. Fourteen patients developed PRES, with an incidence of 5.9/1000 people/year. Those diagnosed with PRES had commonly described PRES symptoms: hypertension, seizures, nausea/vomiting, altered mental status, and headaches. All patients received an magnetic resonance imaging, and most had findings consistent with PRES. Hematopoietic cell transplantation was associated with the development of PRES. The use of Etoposide was associated with PRES but comorbidities, steroids and calcineurin inhibitors were not. While PRES was infrequent in this population, it is associated with high morbidity and mortality, with ICU admissions and an overall hospital mortality, because of secondary causes, of 29%.

BACKGROUND: Early deaths and treatment nonadherence are major reasons for low childhood acute lymphoblastic leukemia (ALL) survival in low- and middle-income countries. This study assessed treatment outcomes of children presenting with ALL and evaluated perspectives of health-care providers (HCP) on ALL treatment at a Kenyan academic hospital. METHODS: This was a combined retrospective medical records and cross-sectional questionnaire study. Treatment outcomes of 136 children diagnosed with ALL between 2010 and 2016 were collected. Questionnaires were completed by 245 HCP (response rate, 86%) between September and October 2016. RESULTS: Childhood ALL treatment outcomes were death (30%), progressive or relapsed disease (26%), abandonment (24%), and event-free survival (20%). Of all deaths, 80% were early deaths (prior or during induction), whereas 20% occurred in remission. Probability of event-free survival at three years was 18%. Only 57% of HCP believed childhood ALL can be cured, with more doctors (96%) than other HCP (45%) believing in curability of ALL (P < 0.001). The majority of HCP (96%) thought that experienced doctors should put more time and effort into making parents understand the diagnosis and necessity to complete treatment. According to HCP, reasons for protocol nonadherence included parental financial difficulties (94%) and use of alternative treatment (79%). CONCLUSIONS: Event-free survival for ALL in Kenya is low. The primary reason for treatment failure is early death from treatment-related complications. More efforts should be directed toward improving supportive care strategies. In the opinion of HCPs, improved communication with parents and supervision of junior staff will improve ALL treatment outcomes.

Long-term outcomes after allogeneic hematopoietic cell transplantation (HCT) for therapy-related myeloid neoplasms (tMNs) are dismal. There are few multicenter studies defining prognostic factors in pediatric patients with tMNs. We have accumulated the largest cohort of pediatric patients who have undergone HCT for a tMN to perform a multivariate analysis defining factors predictive of long-term survival. Sixty-eight percent of the 401 patients underwent HCT using a myeloablative conditioning (MAC) regimen, but there were no statistically significant differences in the overall survival (OS), event-free survival (EFS), or cumulative incidence of relapse and non-relapse mortality based on the conditioning intensity. Among the recipients of MAC regimens, 38.4% of deaths were from treatment-related causes, especially acute graft versus host disease (GVHD) and end-organ failure, as compared to only 20.9% of deaths in the reduced-intensity conditioning (RIC) cohort. Exposure to total body irradiation (TBI) during conditioning and experiencing grade III/IV acute GVHD was associated with worse OS. In addition, a diagnosis of therapy-related myelodysplastic syndrome and having a structurally complex karyotype at tMN diagnosis were associated with worse EFS. Reduced-toxicity (but not reduced-intensity) regimens might help to decrease relapse while limiting mortality associated with TBI-based HCT conditioning in pediatric patients with tMNs.

Vincristine (VCR) is an integral part of chemotherapy regimens in the US and in developing countries. There is a paucity of information about its disposition and optimal therapeutic dosing. VCR is preferentially metabolized to its major M1 metabolite by the polymorphic CYP3A5 enzyme, which may be clinically significant as CYP3A5 expression varies across populations. Thus, it is important to monitor both VCR and M1 and characterize their dispositions. A previously developed HPLC-MS/MS method for VCR quantification was not sensitive enough to quantify the M1 metabolite beyond 1 h post VCR dose (not published). Establishing a highly sensitive assay is a pre-requisite to simultaneously quantify and monitor VCR and M1, which will enable characterization of drug exposure and dispositions of both analytes in a pediatric cancer population. The addition of formic acid during the extraction process enhanced M1 extraction from DBS samples. A sensitive, accurate, and precise UPLC-MS/MS assay method for the simultaneous quantification of VCR and M1 from human dried blood spots (DBS) was developed and validated. Chromatographic separation was performed on Inertsil ODS-3 C18 column (5 µm, 3.0 × 150 mm). A gradient elution of mobile phase A (methanol-0.2 % formic acid in water, 20:80 v/v) and mobile phase B (methanol-0.2 % formic acid in water, 80:20 v/v) was used with a flow rate of 0.4 mL/min and a total run time of 5 min. The analytes were ionized by electrospray ionization in the positive ion mode. The linearity range for both analytes in DBS were 0.6-100 ng/mL for VCR and 0.4-100 ng/mL for M1. The intra- and inter-day accuracies for VCR and M1 were 93.10-117.17 % and 95.88-111.21 %, respectively. While their intra- and inter-day precisions were 1.05-10.11 % and 5.78-8.91 %, respectively. The extraction recovery of VCR from DBS paper was 35.3-39.4 % and 10.4-13.4 % for M1, with no carryover observed for both analytes. This is the first analytical method to report the simultaneous quantification of VCR and M1 from human DBS. For the first time, concentrations of M1 from DBS patient samples were obtained beyond 1 h post VCR dose. The developed method was successfully employed to monitor both compounds and perform pharmacokinetic analysis in a population of Kenyan pediatric cancer patients.

Vincristine is a core chemotherapeutic drug administered to pediatric acute lymphoblastic leukemia patients. Despite its efficacy in treating leukemia, it can lead to severe peripheral neuropathy in a subgroup of the patients. Peripheral neuropathy is a debilitating and painful side-effect that can severely impact an individual's quality of life. Currently, there are no established predictors of peripheral neuropathy incidence during the early stage of chemotherapeutic treatment. As a result, patients who are not susceptible to peripheral neuropathy may receive sub-therapeutic treatment due to an empirical upper cap on the dose, while others may experience severe neuropathy at the same dose. Contrary to previous genomics based approaches, we employed a metabolomics approach to identify small sets of metabolites that can be used to predict a patient's susceptibility to peripheral neuropathy at different time points during the treatment. Using those identified metabolites, we developed a novel strategy to predict peripheral neuropathy and subsequently adjust the vincristine dose accordingly. In accordance with this novel strategy, we created a free user-friendly tool, VIPNp, for physicians to easily implement our prediction strategy. Our results showed that focusing on metabolites, which encompasses both genotypic and phenotypic variations, can enable early prediction of peripheral neuropathy in pediatric leukemia patients.

Chemotherapy-associated cardiotoxicity may delay or impair the ability to administer fully myeloablative chemotherapy for stem cell transplant in those with reduced left ventricular ejection fraction. Studies in adults have been inconsistent regarding the value of ejection fraction in predicting cardiotoxicity in the posttransplant period. Recent publications, however, have demonstrated successful stem cell transplantation in adults despite low ejection fractions. This case series highlights 2 pediatric patients who were successfully treated with stem cell transplantation without posttransplant cardiac complications, despite pretransplant ejection fractions of 38% and 29%.

BACKGROUND: Although attending to spiritual and religious needs is part of high quality care of pediatric cancer patients, oncology clinicians may not understand the role of the chaplain, resulting in underutilization of resources and failure to fully integrate the chaplain into the clinical team. We provide a description of what the chaplain does in the care of pediatric oncology patients. METHODS: We conducted a qualitative content analysis of chaplain chart notes over a one-year period on the pediatric oncology service at a freestanding children's hospital. Using criteria designed to capture multiple potential factors in chaplain referral, we selected 30 patients for thematic analysis. RESULTS: In 2016, 166 pediatric patients were diagnosed with cancer and received ongoing care at our institution. From the 30 patients selected, 230 chaplain encounters were documented in the medical chart. Three major themes emerged. (1) The chaplains provided a rich description of spiritual and psychosocial aspects of the patient and family's experience; (2) chaplains provided diverse interventions, both religious and secular in nature; and (3) chaplains provided care within a longitudinal relationship. All three themes depend on the empathic listening by a chaplain. CONCLUSIONS: The chaplains' observations about patient and family beliefs, experiences, and emotional/spiritual states have the potential to inform the interdisciplinary care of the patient. Chaplain documentation provides insight into how spiritual care interventions and close relationships may promote patient and family well-being. In future work, we will explore how to give voice to their insights in caring for pediatric oncology patients.

Vincristine is one of the core chemotherapy agents used in the treatment of pediatric acute lymphoblastic leukemia (ALL). However, one of the major toxicities resulting from vincristine exposure is vincristine-induced peripheral neuropathy (VIPN). When VIPN results in significant morbidity, the vincristine dose may need to be reduced, thus potentially decreasing the effectiveness of treatment. To date, there are no robust biomarkers used clinically to determine which patients will be at risk for worse neuropathy. The current study included genomewide association study (GWAS) in two independent cohorts: Pediatric Oncology Group (POG) ALL trials and a multicenter study based at Indiana University in children with ALL. A meta-analysis of the cohorts identified two single-nucleotide polymorphisms (SNPs), rs1045644 and rs7963521, as being significantly (P value threshold 0.05/4749 = 1.05E-05) associated with neuropathy. Subsequently these SNPs may be effective biomarkers of VIPN in children with ALL.

Once unimaginable, fertility management is now a nationally established part of cancer care in institutions, from academic centers to community hospitals to private practices. Over the last two decades, advances in medicine and reproductive science have made it possible for men, women and children to be connected with an oncofertility specialist or offered fertility preservation soon after a cancer diagnosis. The Oncofertility Consortium's National Physicians Cooperative is a large-scale effort to engage physicians across disciplines - oncology, urology, obstetrics and gynecology, reproductive endocrinology, and behavioral health - in clinical and research activities to enable significant progress in providing fertility preservation options to children and adults. Here, we review the structure and function of the National Physicians Cooperative and identify next steps.

PURPOSE: Traditional and complementary alternative medicine (TCAM) use is rising globally. In many African countries, TCAM has been a way of life as the first and last resort remedy for many ailments, including cancer. Health-care providers (HCP) should address this need properly. This study explores HCP perspectives on TCAM in Kenya. METHODS: This cross-sectional study used questionnaires. HCP involved in the care of children with cancer at a Kenyan academic hospital were interviewed. RESULTS: In total, 155 HCP (response rate 79%) participated. Only 18% of HCP were positive about TCAM use. However, most HCP (85%) use TCAM themselves. More doctors (90%) than other HCP (56%) think that chemotherapy can cure cancer (P < 0.001).Thirty-three percent of HCP believe a combination of TCAM and chemotherapy is the best way to cure cancer, while 56% think that usefulness of TCAM is underestimated in conventional medicine. Self-prayer is regarded as most effective (58%) and safe (76%). Most harmful is witchcraft (80%). Most HCP (71%) think their knowledge about safety and efficacy of TCAM is inadequate. HCP think that their cancer patients use TCAM (97%) and that it is important that parents inform them about this (97%). However, only 5% of HCP always openly discuss TCAM with parents. CONCLUSIONS: HCP need to improve their knowledge of TCAM and facilitate open communication about TCAM with families so parents feel safe to discuss their interest in it.

BACKGROUND: Patients at Kenyan public hospitals are detained if their families cannot pay their medical bills. Access to health insurance and waiving procedures to prevent detention may be limited. This study explores the perspectives of health-care providers (HCP) on health-insurance access, waiving procedures, and hospital detention practices. PROCEDURE: A self-administered structured questionnaire was completed by 104 HCP (response rate 78%) involved in childhood cancer care. RESULTS: The perspectives of respondents were as follows: all children with cancer should have health insurance according to 96% of HCP. After parents apply for health insurance, it takes too long before treatment costs are covered (67% agree). Patients with childhood cancer without health insurance have a higher chance of abandoning treatment (82% agree). Hospitals should waive bills of all children with cancer when parents have payment difficulties (69% agree). Waiving procedures take too long (75%). Parents are scared by waiving procedures and may decide never to return to the hospital again (68%). Poor families delay visiting the hospital because they fear hospital detention and first seek alternative treatment (92%). When poor families finally come to the hospital, the disease is in advanced stage already (94%). Parents sometimes have to abandon their detained child at the hospital if they cannot pay hospital bills (68%). Detention of children at the hospital if parents cannot pay their medical bills is not approved by 84% of HCP. CONCLUSIONS: HCP acknowledge that access to health insurance needs improvement and that waiving procedures contribute to treatment abandonment. By far, most HCP disapprove of hospital detention practices. These factors warrant urgent attention and adjustment.
