RESUMO

OBJECTIVES: Childhood cancer survivors' social reintegration may be hampered in low and middle-income countries. The nature and extent of social challenges and prejudices that survivors encounter in such settings are largely unknown. This study explores caregivers' perspectives on social reintegration and stigmatization of Kenyan childhood cancer survivors. METHODS: Caretakers of childhood cancer survivors (<18 years) were interviewed using mixed-methods questionnaires during home or clinic visits between 2021 and 2022. Stigma was assessed with an adjusted Social Impact Scale and risk factors were investigated. RESULTS: Caretakers of 54 survivors (median age 11 years) were interviewed. Families' income (93%) decreased since start of treatment. Caretakers (44%) often lost their jobs. Financial struggles (88%) were a burden that provoked conflicts within communities (31%). School fees for siblings became unaffordable (52%). Families received negative responses (26%) and were left or avoided (13%) by community members after cancer disclosure. Survivors and families were discriminated against because the child was perceived fragile, and cancer was considered fatal, contagious, or witchcraft. Survivors repeated school levels (58%) and were excluded from school activities (19%) or bullied (13%). Performance limitations of daily activities (p = 0.019), male sex (p = 0.032), solid tumors (p = 0.056) and a short time since treatment completion (p = 0.047) were associated with increased stigma. Caretakers recommended educational programs in schools and communities to raise awareness about cancer treatment and curability. CONCLUSIONS: Childhood cancer survivors and their families experienced difficulties with re-entry and stigmatization in society. Increasing cancer and survivorship awareness in schools and communities should facilitate social reintegration and prevent stigmatization.

RESUMO

The low incidence of vincristine-induced peripheral neuropathy (VIPN) in Kenyan children may result from low vincristine exposure. We studied vincristine exposure in Kenyan children and dose-escalated in case of low vincristine exposure (NCT05844670). Average vincristine exposure was high. Individual vincristine exposure was assessed with a previously developed nomogram. A 20% dose increase was recommended for participants with low exposure and no VIPN, hyperbilirubinemia, or malnutrition. None of the 15 participants developed VIPN. Low vincristine exposure was seen in one participant: a dose increase was implemented without side effects. In conclusion, the participants did not develop VIPN despite having high vincristine exposure.

RESUMO

BACKGROUND: Awareness could play a key role in reducing underdiagnosis and accelerating referral of childhood cancer in low- and middle-income countries and ultimately improve outcomes. This study describes the implementation of a childhood cancer awareness program in Bungoma County in Kenya, containing five components: (1) baseline data collection of primary healthcare facilities; (2) live training session for healthcare providers (HCP); (3) early warning signs posters; (4) online SMS course for HCP; and (5) radio campaign. METHODS: This study was conducted between January and June 2023. All 144 primary healthcare facilities (level 2 and 3 health facilities) within Bungoma County were visited by the field team. RESULTS: All 125 level 2 (87%) and 19 level 3 (13%) facilities participated in the study. National Health Insurance Fund (NHIF) failed to cover services in 37 (26%) facilities. HCP were more often reported absent at level 3 (89%) than level 2 (64%) facilities (P = 0.034). The 144 live training sessions were attended by over 2000 HCP. Distribution of 144 early warning signs posters resulted in 50 phone calls about suspected childhood cancer cases. Sixteen children were later confirmed with childhood cancer and treated. Online SMS learning was completed by 890 HCP. Knowledge mean scores improved between pre-test (7.1) and post-test (8.1; P < 0.001). Finally, 540 radio messages about childhood cancer and a live question-and-answer session were broadcasted. CONCLUSION: This study described the implementation of a childhood cancer awareness program in Kenya involving both HCP and the general public. The program improved HCP's knowledge and increased the number of referrals for children with cancer.

RESUMO

BACKGROUND: Access to essential childhood cancer medicines is a core determinant of childhood cancer outcomes. Available evidence, although scarce, suggests that access to these medicines is highly variable across countries, particularly in low-income and middle-income countries, where the burden of childhood cancer is greatest. To support evidence-informed national and regional policies for improved childhood cancer outcomes, we aimed to analyse access to essential childhood cancer medicines in four east African countries-Kenya, Rwanda, Tanzania, and Uganda-by determining the availability and price of these medicines and the health system determinants of access. METHODS: In this comparative analysis, we used prospective mixed-method analyses to track and analyse the availability and price of essential childhood cancer medicines, investigate contextual determinants of access to childhood cancer medicines within and across included countries, and assess the potential effects of medicine stockouts on treatment. Eight tertiary care hospitals were included, seven were public sites (Kenyatta National Hospital [KNH; Nairobi, Kenya], Jaramogi Oginga Odinga Referral and Teaching Hospital [JOORTH; Kisumu, Kenya], Moi University Teaching and Referral Hospital [MTRH; Eldoret, Kenya], Bugando Medical Centre [BMC; Mwanza, Tanzania], Muhimbili National Hospital [MNH; Dar es Salaam, Tanzania], Butaro Cancer Centre of Excellence [BCCE; Butaro Sector, Rwanda], and Uganda Cancer Institute [UCI; Kampala, Uganda]) and one was a private site (Aga Khan University Hospital [AKU; Nairobi, Kenya]). We catalogued prices and stockouts for 37 essential drugs from each of the eight study siteson the basis of 52 weeks of prospective data that was collected across sites from May 1, 2020, to Jan 31, 2022. We analysed determinants of medicine access using thematic analysis of academic literature, policy documents, and semi-structured interviews from a purposive sample of health system stakeholders. FINDINGS: Recurrent stockouts of a wide range of cytotoxic and supportive care medicines were observed across sites, with highest mean unavailability in Kenya (JOORTH; 48·5%), Rwanda (BCCE; 39·0%), and Tanzania (BMC; 32·2%). Drugs that had frequent stockouts across at least four sites included methotrexate, bleomycin, etoposide, ifosfamide, oral morphine, and allopurinol. Average median price ratio of medicines at each site was within WHO's internationally accepted threshold for efficient procurement (median price ratio ≤1·5). The effect of stockouts on treatment was noted across most sites, with the greatest potential for treatment interruptions in patients with Hodgkin lymphoma, retinoblastoma, and acute lymphocytic leukaemia. Policy prioritisation of childhood cancers, health financing and coverage, medicine procurement and supply chain management, and health system infrastructure emerged as four prominent determinants of access when the stratified purposive sample of key informants (n=64) across all four countries (Kenya n=19, Rwanda n=15, Tanzania n=13, and Uganda n=17) was interviewed. INTERPRETATION: Access to childhood cancer medicines across east Africa is marked by gaps in availability that have implications for effective treatment delivery for a range of childhood cancers. Our findings provide detailed evidence of barriers to access to childhood cancer medicine at multiple points in the pharmaceutical value chain. These data could inform national and regional policy makers to optimise cancer medicine availability and affordability as part of efforts to improve childhood cancer outcomes specific regions and internationally.

RESUMO

In low- and middle-income countries (LMICs), limited resources, suboptimal risk stratification, and disproportionate patient-to-infrastructure ratio result in low survival of patients with acute myeloid leukemia (AML). A high incidence of relapse, inherent to the biology, renders management arduous. The challenge of treating AML in LMICs is of balancing the intensity of myelosuppressive chemotherapy, which appears necessary for cure, with available supportive care, which influences treatment-related mortality. The recommendations outlined in this paper are based on published evidence and expert opinion. The principle of this adapted protocol is to tailor treatment to available resources, reduce preventable toxic death, and direct limited resources toward those children who are most likely to be cured.

RESUMO

BACKGROUND: Few governments in low and middle-income countries (LMIC) have responded favourably to the international plea for Universal Health Coverage. Childhood cancer survival in LMIC is often below 20%. Limited health-insurance coverage may contribute to this poor survival. Our study explores the influence of health-insurance status on childhood cancer treatment outcomes in a Kenyan academic hospital. METHODS: This was a retrospective medical records review of all children diagnosed with cancer at Moi Teaching and Referral Hospital between 2010 and 2016. Socio-demographic and clinical data was collected using a structured data collection form. Fisher's exact test, chi-squared test, Kaplan-Meier method, log-rank test and Cox proportional hazard model were used to evaluate relationships between treatment outcomes and patient characteristics. Study was approved by Institutional Research Ethics Committee. FINDINGS: From 2010-2016, 879 children were newly diagnosed with cancer. Among 763 patients whose records were available, 28% abandoned treatment, 23% died and 17% had progressive/relapsed disease resulting in 32% event-free survival. In total 280 patients (37%) had health-insurance at diagnosis. After active enrolment during treatment, total health-insurance registration level reached 579 patients (76%). Treatment outcomes differed by health-insurance status (P < 0.001). The most likely treatment outcome in uninsured patients was death (49%), whereas in those with health-insurance at diagnosis and those who enrolled during treatment it was event-free survival (36% and 41% respectively). Overall survival (P < 0.001) and event-free survival (P < 0.001) were higher for insured versus uninsured patients. The hazard-ratio for treatment failure was 0.30 (95% CI:0.22-0.39; P < 0.001) for patients insured at diagnosis and 0.32 (95% CI:0.24-0.41; P < 0.001) for patients insured during treatment in relation to those without insurance. INTERPRETATION: Our study highlights the need for Universal Health Coverage in LMIC. Children without health-insurance had significantly lower survival. Childhood cancer treatment outcomes can be ameliorated by strategies that improve health-insurance access.

RESUMO

BACKGROUND: The COVID-19 pandemic is of grave concern. As scientific data is being collected about the nature of COVID-19, government leaders and policy makers are challenged. They might feel pressured to take strong measures to stop virus spread. However, decisions could cause more harm than do good. This study maps all existing literature regarding the impact of COVID-19 containment measures on the health and healthcare of children in East-Africa. METHODS: This scoping review follows Population Concept Context guidelines of Arksey and O'Malley and PRISMA 2020 checklist. PubMed, Web of Science, and Embase were searched. All peer-reviewed literature published in English between January 2020 and October 2022 was considered. Initial screening of titles and abstracts was undertaken independently by two reviewers, with a third available in case of doubt. This was followed by full-text screening involving two independent reviewers. RESULTS: In total, 70 studies were included. Eight containment measures affecting children's health and healthcare were distinguished: lockdowns, school closures, physical distancing, travel restrictions, business closures, stay-at-home orders, curfews, quarantine measures with contact tracing. The consensus in the studies is that containment measures could minimise COVID-19 spread but have adverse indirect effects on children in East-Africa. Seven indirect effects were distinguished: economic damage, limited education access, food insecurity, child abuse, limited healthcare access, disrupted health-programs, and mental health challenges. CONCLUSION: Government leaders and policy makers should take adverse indirect effects of COVID-19 measures into account, particularly in resource-limited regions such as East-Africa, apply a holistic approach, and strengthen socioeconomic and health-systems to protect the most vulnerable.

RESUMO

BACKGROUND: Children with sickle cell anemia (SCA) in areas of Africa with endemic malaria transmission are commonly prescribed malaria chemoprevention. Chemoprevention regimens vary between countries, and the comparative efficacy of prevention regimens is largely unknown. METHODS AND FINDINGS: We enrolled Kenyan children aged 1 to 10 years with homozygous hemoglobin S (HbSS) in a randomized, open-label trial conducted between January 23, 2018, and December 15, 2020, in Homa Bay, Kenya. Children were assigned 1:1:1 to daily Proguanil (the standard of care), monthly sulfadoxine/pyrimethamine-amodiaquine (SP-AQ), or monthly dihydroartemisinin-piperaquine (DP) and followed monthly for 12 months. The primary outcome was the cumulative incidence of clinical malaria at 12 months, and the main secondary outcome was the cumulative incidence of painful events by self-report. Secondary outcomes included other parasitologic, hematologic, and general events. Negative binomial models were used to estimate incidence rate ratios (IRRs) per patient-year (PPY) at risk relative to Proguanil. The primary analytic population was the As-Treated population. A total of 246 children were randomized to daily Proguanil (n = 81), monthly SP-AQ (n = 83), or monthly DP (n = 82). Overall, 53.3% (n = 131) were boys and the mean age was 4.6 ± 2.5 years. The clinical malaria incidence was 0.04 episodes/PPY; relative to the daily Proguanil group, incidence rates were not significantly different in the monthly SP-AQ (IRR: 3.05, 95% confidence interval [CI]: 0.36 to 26.14; p = 0.39) and DP (IRR: 1.36, 95% CI: 0.21 to 8.85; p = 0.90) groups. Among secondary outcomes, relative to the daily Proguanil group, the incidence of painful events was not significantly different in the monthly SP-AQ and DP groups, while monthly DP was associated with a reduced rate of dactylitis (IRR: 0.47; 95% CI: 0.23 to 0.96; p = 0.038). The incidence of Plasmodium falciparum infection relative to daily Proguanil was similar in the monthly SP-AQ group (IRR 0.46; 95% CI: 0.17 to 1.20; p = 0.13) but reduced with monthly DP (IRR 0.21; 95% CI: 0.08 to 0.56; p = 0.002). Serious adverse events were common and distributed between groups, although compared to daily Proguanil (n = 2), more children died receiving monthly SP-AQ (n = 7; hazard ratio [HR] 5.44; 95% CI: 0.92 to 32.11; p = 0.064) but not DP (n = 1; HR 0.61; 95% CI 0.04 to 9.22; p = 0.89), although differences did not reach statistical significance for either SP-AQ or DP. Study limitations include the unexpectedly limited transmission of P. falciparum in the study setting, the high use of hydroxyurea, and the enhanced supportive care for trial participants, which may limit generalizability to higher-transmission settings where routine sickle cell care is more limited. CONCLUSIONS: In this study with limited malaria transmission, malaria chemoprevention in Kenyan children with SCA with monthly SP-AQ or DP did not reduce clinical malaria, but DP was associated with reduced dactylitis and P. falciparum parasitization. Pragmatic studies of chemoprevention in higher malaria transmission settings are warranted. TRIAL REGISTRATION: clinicaltrials.gov (NCT03178643).

RESUMO

BACKGROUND/OBJECTIVES: Wilms tumor (WT) is a curable type of cancer with 5-year survival rates of over 90% in high-income countries, whereas this is less than 50% in low- and middle-income countries. We assessed treatment outcomes of children with WT treated at a large Kenyan teaching and referral hospital. DESIGN/METHODS: We conducted a retrospective record review of children diagnosed with WT between 2013 and 2016. Treatment protocol consisted of 6 weeks of preoperative chemotherapy and surgery, and 4-18 weeks of postoperative chemotherapy depending on disease stage. Probability of event-free survival (pEFS) and overall survival (pOS) was assessed using Kaplan-Meier method with Cox regression analysis. Competing events were analyzed with cumulative incidences and Fine-Gray regression analysis. RESULTS: Of the 92 diagnosed patients, 69% presented with high-stage disease. Two-year observed EFS and OS were, respectively, 43.5% and 67%. Twenty-seven percent of children died, 19% abandoned treatment, and 11% suffered from progressive or relapsed disease. Patients who were diagnosed in 2015-2016 compared to 2013-2014 showed higher pEFS. They less often had progressive or relapsed disease (p = .015) and borderline significant less often abandonment of treatment (p = .09). Twenty-nine children received radiotherapy, and 2-year pEFS in this group was 86%. CONCLUSION: Outcome of children with WT improved over the years despite advanced stage at presentation. Survival probabilities of patients receiving comprehensive therapy including radiation are approaching those of patients in high-income countries. Additional improvement could be achieved by ensuring that patients receive all required treatment and working on earlier diagnosis strategies.

RESUMO

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.

RESUMO

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.

RESUMO

BACKGROUND: Death during paediatric cancer treatment is common in sub-Saharan Africa. Using the infrastructure of Supportive Care for Children with Cancer in Africa (SUCCOUR), our objective was to describe fever and neutropenia (FN) characteristics and outcomes in order to identify potential areas for future intervention. METHODS: A multicentre prospective, observational cohort study was conducted in sub-Saharan Africa. Data were collected from September 2019 to March 2020. Children below 16 years with newly diagnosed cancer treated with curative intent were included. Data were abstracted in real time using standardised case report forms by trained personnel. Characteristics and outcomes of FN during the first 3 months of treatment were documented. RESULTS: A total of 252 patients were included (median age 6.0, range 0.2-15.0 years, 54% male). The most common cancer was Burkitt lymphoma (63/252, 25%). Among 104 FN episodes, 21 (21%) were associated with prolonged neutropenia (>1 week) and 32 (31%) were associated with profound neutropenia (absolute neutrophil count <0.1 × 109 /L). In 10/104 (10%) episodes, empiric antibiotics were started within 1 hour following fever onset and in 16/104 (15%) episodes, a blood culture was obtained before starting antibiotics. Malaria parasitaemia was detected in four of 104 (4%). A total of 11/104 (11%) patients died in the FN episodes. CONCLUSIONS: Although in most, FN was not associated with prolonged or profound neutropenia, 11% resulted in death. Areas to target include blood cultures prior to antibiotics and earlier initiation of empiric antibiotics. Future efforts should modify FN practices to reduce treatment-related mortality.

RESUMO

BACKGROUND: Deaths during paediatric cancer treatment are common in Africa. It is often difficult to distinguish between treatment-related and disease-related causes. To prevent these deaths, it is important to study them and identify the cause. The Supportive Care for Children with Cancer in Africa (SUCCOUR) programme enabled a study with the objective to identify the reasons for early death during treatment. METHODS: We conducted a multicentre prospective, observational cohort study in sub-Saharan Africa. Children younger than 16 years with newly diagnosed cancer treated with curative intent were included from 1 September 2019 until 30 March 2020. Data were abstracted in real time by trained personnel using standardised case report forms. The treating clinician's assessment of the cause of death and signs, symptoms and laboratory values of patients who died during the first 3 months of treatment (early death) were documented. RESULTS: We included 252 patients (median age 6.0, range 0.2-15.0 years, 54% male). The most common cancer was Burkitt lymphoma (63/252, 25%). Fifteen percent of patients (37/252) died during the first 3 months of treatment. Of these 37 patients, 33 (89%) died of a treatment-related cause. Treatment-related mortality of all patients in the first 3 months of treatment was 13% (33/252). CONCLUSION: Fifteen percent of patients had an early death during treatment and 13% had a treatment-related death. This suggests the need to improve supportive care. Implementation of supportive care pathways adapted to local circumstances may be helpful.

RESUMO

BACKGROUND: 'Treatmentabandonment' is a common and preventable cause of childhood cancer treatment failure in low- and middle-income countries (LMIC). Risk factors and effective interventions in LMIC are reported. Poverty and costs of treatment are perceived as overriding causes in sub-Saharan Africa. The objective of this study was to study potential determinants of treatment abandonment, including aspects of treatment costs in sub-Saharan Africa, to be better informed for planned future interventions. METHODS: A multicentre, prospective, observational, cohort study was conducted in five hospitals in sub-Saharan Africa. Children younger than 16 years with newly diagnosed cancer treated as inpatient with curative intent were included. The occurrence of treatment abandonment and potential determinants including aspects of treatment costs were documented during the first 3 months of treatment. RESULTS: We included 252 patients (median age 6.0, range 0.2-15.0 years, 54% male). The most common cancer was Burkitt lymphoma (63/252, 25%). Seven percent of patients (18 of 252) abandoned treatment. Two thirds (65%, 163/252) of patients had to borrow money to reach the hospital for the diagnosis and start of treatment. Treatment abandonment occurred more frequently in families who had to borrow money (16/163, 10%) versus those who did not (2/89, 2%; p = .026). CONCLUSIONS: Limiting costs for families and improved counselling may reduce treatment abandonment. Development and implementation of interventions to reduce treatment abandonment are required in sub-Saharan Africa.

RESUMO

OBJECTIVES: To characterize the types and magnitude of psychosocial burden present in caregivers who have a child with sickle cell disease (SCD) in Kenya and to identify predictors of caregiver psychosocial burden, including disease severity and financial hardship. METHODS: Primary caregivers (N = 103) of children aged 1-10 years diagnosed with SCD completed surveys assessing multiple domains of caregiver quality of life (QOL), adjustment to child illness, mental health, and financial hardship. Descriptive statistics characterize psychosocial burden, and linear models assess associations. RESULTS: On indicators of QOL, caregivers report multiple difficulties across most domains, including daily activities and physical, social, cognitive, and emotional well-being. Daily activities emerged as most burdensome. On indicators of parental adjustment to chronic illness, guilt and worry emerged as the greatest concern, followed by long-term uncertainty and unresolved sorrow and anger; relative to these, they reported higher levels of emotional resources. Financial hardship was high, as caregivers reported moderate to major financial losses due to the time spent caring for their child. General linear model analyses revealed that level of financial hardship was a significant predictor of all negative psychosocial outcomes. CONCLUSIONS: Results document that Kenyan caregivers of children with SCD experience difficulties across multiple domains of functioning and that financial difficulties are likely associated with psychosocial burden. Results can guide intervention development for caregivers of children with SCD in low-resource, global contexts.

RESUMO

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.

RESUMO

BACKGROUND: Vincristine (VCR) is a critical part of treatment in pediatric malignancies and is associated with dose-dependent peripheral neuropathy (vincristine-induced peripheral neuropathy [VIPN]). Our previous findings show VCR metabolism is regulated by the CYP3A5 gene. Individuals who are low CYP3A5 expressers metabolize VCR slower and experience more severe VIPN as compared to high expressers. Preliminary observations suggest that Caucasians experience more severe VIPN as compared to nonCaucasians. PROCEDURE: Kenyan children with cancer who were undergoing treatment including VCR were recruited for a prospective cohort study. Patients received IV VCR 2 mg/m2 /dose with a maximum dose of 2.5 mg as part of standard treatment protocols. VCR pharmacokinetics (PK) sampling was collected via dried blood spot cards and genotyping was conducted for common functional variants in CYP3A5, multi-drug resistance 1 (MDR1), and microtubule-associated protein tau (MAPT). VIPN was assessed using five neuropathy tools. RESULTS: The majority of subjects (91%) were CYP3A5 high-expresser genotype. CYP3A5 low-expresser genotype subjects had a significantly higher dose and body surface area normalized area under the curve than CYP3A5 high-expresser genotype subjects (0.28 ± 0.15 hr·m2 /l vs. 0.15 ± 0.011 hr·m2 /l, P = 0.027). Regardless of which assessment tool was utilized, minimal neuropathy was detected in this cohort. There was no difference in the presence or severity of neuropathy assessed between CYP3A5 high- and low-expresser genotype groups. CONCLUSION: Genetic factors are associated with VCR PK. Due to the minimal neuropathy observed in this cohort, there was no demonstrable association between genetic factors or VCR PK with development of VIPN. Further studies are needed to determine the role of genetic factors in optimizing dosing of VCR for maximal benefit.

RESUMO

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.

RESUMO

PURPOSE: Traditional and complementary medicine (T&CM) use in children with cancer is well established among high-income, upper middle-income, low-middle-income, and low-income countries (HIC, UMIC, LMIC, LIC, respectively). In HIC, a developing body of evidence exists for several T&CM therapies; however, evidence in other income settings is less well described despite a significantly higher use when compared to reports from HIC. The aim of this systematic review was to evaluate the evidence for T&CM for a variety of supportive care indications among children with cancer. METHODS: We performed a systematic review following the PRISMA guidelines of randomized, controlled clinical trials from inception through September 2016. Our eligibility criteria were limited to T&CM studies performed in children and adolescents undergoing treatment for a pediatric malignancy. RESULTS: Of 6342 studies identified, 44 met inclusion criteria. Two clinical trials reported on acupuncture, 1 reported on aromatherapy, 9 evaluated massage therapy, and 32 reported on dietary supplements. Twenty-two studies were performed in HIC, 15 in UMIC, and 7 in LMIC. T&CM therapies were most commonly investigated for the prevention or management of mucositis, weight loss, and febrile neutropenia. Encouraging results were reported for select interventions; however, the majority of studies were classified as poor to fair quality. CONCLUSION: Our search revealed numerous clinical studies investigating the use of T&CM for supportive care purposes in pediatric oncology in HIC, UMIC, and LMIC. Although limited, these results could inform supportive care resource allocation and indicate where T&CM may serve to fill gaps where access to care may be limited.
