Delayed diagnostic interval and survival outcomes in pediatric leukemia: A single-center, retrospective study. Eur J Haematol 2024; 112:714-722. [PMID: 38152024 DOI: 10.1111/ejh.14162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/03/2023] [Revised: 12/11/2023] [Accepted: 12/12/2023] [Indexed: 12/29/2023]
Abstract
OBJECTIVE This study primarily focused on the diagnostic interval (DI), defined as the duration from the onset of leukemic symptoms to diagnosis. We investigated whether a prolonged DI is associated with the outcomes of pediatric leukemia. METHODS We retrospectively collected data of children with newly diagnosed pediatric leukemia at Okayama University Hospital from January 2007 to December 2022. Survival analyses were conducted using Kaplan-Meier methods, and an unadjusted analysis to compare differences in survival was performed using the log-rank test. RESULTS In total, 103 children with leukemia were included in the analysis. The median DI was 20 days (interquartile range, 9.5-33.5 days). A prolonged DI (≥30 days) demonstrated no association with either 5-year event-free survival (70.1% for <30 days and 68.3% for ≥30 days, p = .99, log-rank test) or overall survival (84.7% for <30 days and 89.4% for ≥30 days, p = .85, log-rank test). CONCLUSIONS A prolonged DI was not associated with the survival of children with leukemia. If a precise classification of leukemia biology is provided for pediatric patients, a prolonged DI may have little impact on the prognosis of these patients.

Abstract
Acute lymphoblastic leukemia (ALL) is the most common childhood malignancy, with diagnosis preceded by symptoms that may include fever, weight loss, fatigue, bleeding, and bruising. Timely diagnosis and treatment of ALL may lead to improved outcomes and reduced morbidity from associated complications, including tumor lysis syndrome, hyperviscosity, and stroke. We performed a retrospective cohort analysis of 274 pediatric pre-B cell ALL and acute lymphoblastic lymphoma patients within Montefiore Health System to determine whether there were factors associated with time from symptom onset to diagnosis. The median time to diagnosis for all patients was 11.5 days (interquartile range: 7.8, 14.3). Those with Medicaid insurance (n=189) were diagnosed sooner than those with private/self-pay insurance (n=85) (median of 10 vs. 16 days; P =0.05). English and other language speakers experienced fewer median days from symptom onset to diagnosis date compared with Spanish speakers (11 vs. 7 vs. 14; P =0.05). Insurance status may impact the time to diagnosis to a greater degree in non-Hispanic patients, while the English language and female sex may represent a greater advantage to Hispanic patients. Insurance status and language preference may impact the time to diagnosis of pediatric ALL. There is a further need to confirm our findings and to study possible causes driving these disparities.

Abstract
Introduction More than 85% of childhood malignancies occur in developing countries with less than a 30% cure rate as opposed to more than 80% cure rate in developed countries. This disproportionately significant difference might be due to delays in diagnosis, treatment initiation, lack of adequate supportive care, and treatment abandonment. We aimed to determine the impact of overall treatment delay on induction mortality of children with acute lymphoblastic leukemia treated at Tikur Anbessa specialized hospital (TASH). Methods A cross-sectional study was conducted among children who were treated from 2016 to 2019. Children with Down syndrome and relapsed leukemia were excluded from this study. Results A total of 166 children were included; most patients were males (71.7%). The mean age at diagnosis was 5.9 years. The median time interval from the onset of symptoms to the first TASH visit was 30 days and the median period from TASH's first clinic visit to diagnosis was 11 days. The median time to initiate chemotherapy after diagnosis was 8 days. The total median time from the first onset of symptoms to chemotherapy initiation was 53.5 days. Induction mortality was 31.3%. High-risk ALL and patients with an overall delay between 30 and 90 days were more likely to experience induction mortality. Discussion Patient and healthcare system delay is high compared to most studies done and a significant association has been noted with induction mortality. Efforts to expand the pediatric oncology service in the country and efficient diagnostic and treatment approach need to be established to reduce mortality associated with overall delay.

Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) is the most common childhood cancer. Early diagnosis and timely treatment are essential for effective cancer control and have been widely analyzed in childhood cancer. However, few studies have described the time to diagnosis and treatment in children with ALL. This study investigated delays in diagnosis and treatment initiation and their impact on survival. METHODS This retrospective cohort study included 419 patients 0 to 14 years old at a tertiary hospital between 2011 and 2015. The optimal cutoff values for delays were determined by X-tile software. The Kaplan-Meier method and Cox regression models were used to evaluate the impact of delays on survival. RESULTS The median diagnosis, treatment, and total delays were 21 (interquartile range [IQR]: 11-35), 4 (IQR: 2-7), and 26 (IQR: 16-43) days, respectively. The results of multivariate analyses showed that diagnosis delay, risk stratification, and minimal residual disease level were independent predictors for treatment outcome in childhood ALL. CONCLUSIONS These findings suggested that a longer time to diagnosis negatively affected the clinical outcome of childhood ALL. Reducing the time to diagnosis could help to improve survival in these patients.

How can fertility counseling be implemented for every newly diagnosed pediatric patient facing gonadotoxic treatment?-A single-center experience. Ann Hematol 2021; 100:2831-2841. [PMID: 34536088 PMCID: PMC8510917 DOI: 10.1007/s00277-021-04648-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2021] [Accepted: 08/17/2021] [Indexed: 11/14/2022]
Abstract
Since the survival rates of pediatric patients undergoing cancer treatment or hematopoietic stem cell transplantation (HSCT) have increased rapidly in recent decades, the late effects of treatment are now an important focus of patient care. Access to fertility preservation (FP) procedures as well as their financing differs considerably across Europe. However, some countries in Europe have recently changed the legal basis for financing FP procedures; therefore, the implementation of structures is mandatory to give patients access to FP. In this prospective cohort study, we characterized the process for establishing pediatric fertility counseling, including the development of an in-house standard procedure for recommendations regarding FP with potentially gonadotoxic treatment and valuating data from all FP counseling sessions. All data concerning patient characteristics (pubertal status, disease group) and recommendation of FP measures were prospectively collected and adoption of FP measures analyzed. Prior to the establishment of a structured process for FP in our pediatric oncology and stem cell transplantation center, there was no standardized FP counseling. We demonstrate that with the establishment of an inhouse standard procedure, it is possible to give consistent yet individualized FP counseling to approximately 90% of our patients facing gonadotoxic treatment, counseling over 200 patients between 2017 and 2019. This pilot study could potentially be adapted in other pediatric hematology, oncology, and stem cell transplantation centers to allow a more standardized handling of FP counseling for all patients facing gonadotoxic treatment.

Population-Based Analysis of Demographic and Socioeconomic Disparities in Pediatric CNS Cancer Survival in the United States. Sci Rep 2020; 10:4588.

Abstract
Previous studies have demonstrated effects of racial and socioeconomic factors on survival of adults with cancer. While less studied in the pediatric population, data exist demonstrating disparities of care and survival in pediatric oncology patients based on socioeconomic and racial/ethnic factors. Brain cancers recently overtook leukemia as the number one cause of childhood cancer fatalities, but demographic and socioeconomic disparities in these tumors have not been adequately studied. We obtained data from the SEER Program of the National Cancer Institute (NCI). We selected patients under 19 years of age with central nervous system (CNS) cancers diagnosed between 2000 and 2015. We included patient demographics, tumor characteristics, treatment, and socioeconomic characteristics as covariates in the analysis. We measured overall survival and extent of disease at diagnosis. We saw that Black and Hispanic patients overall had a higher risk of death than non-Hispanic White patients on multivariable analysis. On stratified analysis, Black and Hispanic patients with both metastatic and localized disease at diagnosis had a higher risk of death compared to White, non-Hispanic patients, although the difference in Black patients was not significant after adjusting for mediating factors. However, our findings on extent of disease at diagnosis demonstrated that neither Black race nor Hispanic ethnicity increased the chance of metastatic disease at presentation when controlling for mediating variables. In summary, racial and ethnic disparities in childhood CNS tumor survival appear to have their roots at least partially in post-diagnosis factors, potentially due to the lack of access to high quality care, leading to poorer overall outcomes.

Abstract
BACKGROUND Not all children with acute lymphoblastic leukemia (ALL) were developing in a typical manner prior to diagnosis. Pre-existing developmental vulnerabilities (DV) may be related to long-term neuropsychological sequelae following ALL treatment, yet little is known about the prevalence or nature of prior DV in this population. PROCEDURE Children with newly diagnosed ALL aged 2-18 years (n = 115) were screened for DV by asking parents about the child's prior developmental history and with the Developmental Profile-3 (DP-3). RESULTS Twenty-six participants (23% of total sample) screened positive for prior DV, with one or more of the following: delayed early motor and/or language milestones that required intervention (n = 17), prior diagnosis of Down syndrome (n = 3), prior diagnosis of autism spectrum disorder (n = 1), prior diagnosis of attention-deficit/hyperactivity disorder and/or learning disability (n = 6), or prior neurological conditions (n = 5). CONCLUSIONS A sizable proportion of children with newly diagnosed ALL have pre-morbid DV that could potentially make them more vulnerable to reduced educational opportunities during treatment and neurotoxic late effects following treatment. Identification of the subset of children with ALL and DV is essential to direct early interventions and to study their long-term outcomes.
