Significance of CEBPE Gene Promoter Polymorphism (Rs2239630 G > A ) Assessment in Childhood B-cell Acute Lymphoblastic Leukemia.

BACKGROUND: A significant association has been reported between CEBPE gene promoter polymorphisms (rs2239630 G > A ) and the incidence of B-cell acute lymphoblastic leukemia (B-ALL). However, no previous study on this issue has been included among the Egyptian cohort of pediatric patients with B-ALL. Therefore, this study was designed to address the associations between CEBPE polymorphisms and susceptibility to B-ALL, as well as its impact on the outcome of B-ALL Egyptian patients with B-ALL. PATIENTS AND METHODS: In the current study, we evaluated the rs2239630 polymorphism in 225 pediatric patients and 228 controls to assess the association of different rs2239630 genotypes with childhood susceptibility to B-ALL and the impact on the outcome of the patients. RESULTS: The frequency of the A allele was significantly higher in the cases of B-ALL compared with the control group ( P = 0.004). By analyzing different genotypes for the predictive value of disease development, the GA and AA genotypes have been identified to be the highest among multivariate factors with an odds ratio of 3.330 (95% CI: 1.105-10.035). Likewise, the A allele was significantly associated with the shortest overall survival. CONCLUSIONS: CEBPE gene promoter polymorphism (rs2239630 G > A ) AA is frequently associated with B-ALL; and has the worst overall survival among the 3 genotypes, followed by the GA and GG genotypes ( P < 0.001).

Effects of COVID-19 on Pediatric Cancer Care: A Multicenter Study of 11 Middle Eastern Countries.

During the COVID-19 pandemic, major challenges are facing pediatric cancer centers regarding access to cancer centers, continuity of the anti-cancer therapy, hospital admission, and infection protection precautions. Pediatric oncologists actively treating children with cancer from 29 cancer centers at 11 countries were asked to answer a survey from May 2020 to August 2020 either directly or through the internet. COVID-19 pandemic affected the access to pediatric cancer care in the form of difficulty in reaching the center in 22 (75.9%) centers and affection of patients' flow in 21 (72.4%) centers. Health care professionals (HCP) were infected with COVID-19 in 20 (69%) surveyed centers. Eighteen centers (62%) modified the treatment guidelines. Care of follow-up patients was provided in-hospital in 8(27.6%) centers, through telemedicine in 10 (34.5%) centers, and just delayed in 11 (38%) centers. Pediatric oncologists had different expectations about the future effects of COVID-19 on pediatric cancer care. Seventy-six percent of pediatric oncologists think the COVID-19 pandemic will increase the use of telemedicine. Fifty-five percent of pediatric oncologists think if the COVID-19 pandemic persists, we will need to change chemotherapy protocols to less myelosuppressive ones. Collaborative studies are required to prioritize pediatric cancer management during COVID-19 era.

Treatment outcomes of children with acute lymphoblastic leukemia in a middle-income developing country: high mortalities, early relapses, and poor survival / Desfechos do tratamento de crianças com leucemia linfoblástica aguda em um paísem desenvolvimento de renda média: altas taxas de mortalidade, recidivas precocese baixa sobrevida

Abstract Objective Acute lymphoblastic leukemia is the most common childhood cancer, yet surprisingly, very few studies have reported the treatment outcomes and the relapse rate of patients from low/middle-income countries. Method This study was a 5-year retrospective cohort study. It was conducted at Oncology Center of Mansoura University in Egypt and aimed to estimate the treatment outcomes and the relapse rates of newly diagnosed acute lymphoblastic leukemia in children. Results Two hundred children suffering from acute lymphoblastic leukemia were studied; forty-six patients (23%) died during induction and most of those deaths were related to infection. Forty-one patients (27%) relapsed out of the 152 patients who achieved complete remission. The most common site of relapse was the bone marrow, followed by the isolated central nervous system, 53.7% and 31.7%, respectively. Seventy-eight percent of relapses occurred very early/early rather than later. The majority of relapse patients' deaths were related to infection and disease progression. The 5-year overall survival rate for patients was 63.1% (82.1% for non-relapsed compared to 36.6% for relapsed patients). Conclusion There was a high incidence of induction deaths related to infection and high percentages of very early/early relapses, with high mortalities and low 5-year overall survival rates. These findings suggest the urgent need for modification of chemotherapy regimens to be suitable for the local conditions, including implementation of supportive care and infection control policies. There is also a requirement for antimicrobial prophylaxis during induction period combined with the necessary increase in government healthcare spending to improve the survival of acute lymphoblastic leukemia in Egyptian children.

Resumo Objetivo Estimar os desfechos do tratamento e as taxas de recidiva de crianças recém-diagnosticadas com leucemia linfoblástica aguda. É o câncer infantil mais comum, mas surpreendentemente poucos estudos relataram os desfechos do tratamento e a taxa de recidiva em pacientes de países de renda baixa/média. Método Estudo de coorte retrospectivo de cinco anos. Foi feito no Centro de Oncologia da Universidade de Mansoura, no Egito. Resultados Foram estudadas 200 crianças com leucemia linfoblástica aguda, das quais 46 (23%) morreram durante a indução e a maioria dessas mortes estava relacionada à infecção. Dos 152 pacientes que alcançaram a remissão completa, 41 (27%) apresentaram recidiva. O local mais comum de recidiva foi a medula óssea, seguido pelo sistema nervoso central isolado, com 53,7% e 31,7% dos casos, respectivamente. Das recidivas, 78% ocorreram muito precocemente ou precocemente, em vez de tardiamente. A maioria das mortes de pacientes com recidiva estava relacionada à infecção e progressão da doença. A taxa de sobrevida global em cinco anos para os pacientes foi de 63,1% (82,1% para não recidivados em comparação com 36,6% para os recidivados). Conclusão Houve uma alta incidência de mortes na indução relacionadas à infecção e altos percentuais de recidivas muito precoces ou precoces, com altas taxas de mortalidade e baixas taxas de sobrevida global em cinco anos. Nossos achados sugerem a necessidade urgente de modificação dos esquemas quimioterápicos para adequação às nossas condições locais, implantação de políticas de cuidados de suporte e controle de infecções. Há também a necessidade de profilaxia antimicrobiana durante o período de indução, junto com um aumento necessário nos gastos governamentais com a saúde, para melhorar a capacidade de sobrevivência das crianças egípcias com leucemia linfoblástica aguda.

Psychiatric Disorders and Quality of Life in Egyptian Patients with Chronic Immune Thrombocytopenic Purpura: A Single Center Study.

The impact of chronic immune thrombocytopenic purpura (ITP) on the psychological health and quality of life is evident among children and adolescents. We aimed to describe psychological disorders and assess quality of life in children with chronic ITP and compared their results with their healthy peers. A cross-sectional comparative study was carried out in a tertiary care university-affiliated hospital during a period from November, 2015 till April, 2018. We enrolled 119 children with chronic ITP and compared with 220 healthy peers. Relevant demographic and clinical data were collected and statistically analyzed. Quality of life for both patients and control groups was measured using pediatric quality of life inventory version 4 (Arabic one). Also psychiatric evaluation of both groups was done using Arabic version of Mini-International Neuropsychiatric Interview for Children (Mini-KID). Majority of patients (90.7%) exhibited mucocutaneous bleeding. Most of patients (61.3%) did not need any definitive treatment for chronic ITP while 38.6% received second line therapy. About one-third of the patients needed rescue medications to control active bleeding. The scores of all sub-scales of Peds QL 4.0 were significantly decreased among patients group when compared to their healthy peers (P < 0.001). General anxiety disorder and oppositional defiant disorders were the commonest psychiatric disorders among children with chronic ITP. Quality of life in children with chronic ITP is markedly impaired with occurrence of a variable spectrum of psychiatric disorders among the studied patients.

An Analysis of Overweight and Obesity Status among Childhood Cancer Survivors in Saudi Arabia: A Single Center Study.

Overweight and obesity in the pediatric population remains a growing worldwide health burden. The extent to which this trend extends to childhood cancer survivors (CCS) remains less well explored. We conducted a retrospective observational study from a single institution in Saudi Arabia to estimate the prevalence of overweight and obese status among CCS over a five-year period. A total of 91 CCS patients were identified, 63 of whom had complete weight data from their treatment to the time of the study. Of these patients, 29 (46.0%) were found to be overweight or obese [body mass index (BMI) ≥85th percentile] at the time of the study. Of these patients, this rate was particularly high for patients who were female, older at the time of diagnosis (>6 years) (72.8%) and among pubescent patients (Tanner 3-5 at diagnosis). The rate of overweight and obesity increased from 31.7% immediately after the end of treatment (average age of 7.1 years) to 36.5% one year after. Thereafter, these percentages increased to approximately 38% over the 5-year follow-up period and increased beyond that up to 46%. A high prevalence of overweight and obesity among CCS was found at the end of their treatment with an observed increasing trend towards overweight and obesity in the following years, suggesting the need for early and continuous intensive intervention and frequent dietary evaluation.

Delays in diagnosis and treatment among children with cancer: Egyptian perspective.

Delayed diagnosis is one of the contributing factors to lower cure rates for cancer in low-income countries. This was a cross-sectional study of 138 children with cancer who were treated at the Pediatric Oncology Unit, Oncology Center of Mansoura University, Egypt. One hundred and sixteen patients were initially misdiagnosed. The median total delay was 37 days, including median patient/parent delay of 3 days and median physician delay of 28 days. The type of cancer significantly influenced the diagnostic delay. Patients' sex, level of parents' education, and residence did not significantly affect the median total delay, while patients aged < 5 years and those who had an initial provisional diagnosis of cancer had the shortest median total delay. We suggest implementation of continuing medical education programmes, improving access to diagnostic facilities, and facilitating referral to give priority to those with suspected cancer to shorten the time for cancer diagnosis.
