Abstract
The present study aimed to investigate the real-world results of childhood acute lymphoblastic leukemia (cALL) cases in Fujian, China. The clinical data of 1414 patients with newly diagnosed cALL in Fujian were retrospectively analyzed. Patients were treated according to the Chinese Children Leukemia Group 2008 protocol (CCLG-ALL 2008 group) or Chinese Children's Cancer Group 2015 protocol (CCCG-ALL 2015 group). Cumulative incidence of treatment abandonment (TA) at 5 years was 4.2% ± 0.6% and significantly associated with treatment period and risk stratification. The 5-OS and EFS were significantly higher in the CCCG-ALL 2015 group than in the CCLG-ALL 2008 group. Patients treated with CCCG-ALL 2015 from Fujian Medical Union Hospital had a significantly higher 4-year OS and EFS than did those from the other four hospitals. Real-world TA of cALL greatly decreased, and its long-term survival significantly increased in Fujian, which may be related to optimizing programs, multi-center collaboration, and improving treatment compliance.

Abstract
INTRODUCTION Insurance status at diagnosis remains an important barrier to health care access and adherence to treatment. Here, we aim to assess the impact of insurance status, and age on overall survival (OS) in patients with acute lymphoblastic leukemia (ALL). MATERIALS AND METHODS Using the Surveillance, Epidemiology, and End Results database, we identified all patients younger than 65 years of age diagnosed with ALL from 2010 to 2016. OS was estimated for each group using the Kaplan Meier curves and compared based on insurance type using a log-rank test. Multivariate analysis using Cox proportional hazard regression model was used to assess the effect of insurance status on OS. RESULTS A total of 9057 patients were included in the analysis. Medicaid beneficiaries had worse 5-year OS than insured patients (HR 1.33, 95% CI 1.08-1.63, P = .006) in 0-18 years age group. Despite chemotherapy, patients older than 18 years showed poor OS in all insurance categories. Patients on Medicaid showed inferior OS compared to insured in 19-40 years (HR 1.46, 95% CI 1.21-1.76, P < .001) and 41-65 years age group (HR 1.27, 95% CI 1.09-1.49, P = .003). Interestingly, no significant difference was observed in the OS between the Medicaid and uninsured groups in each age category. CONCLUSION Our large database study demonstrates that insured status is associated with better OS in ALL across all age groups. Further studies to develop effective strategies to bridge health care disparities areessential.

[PMID: 35468327 DOI: 10.1016/s2352-4642(22)00095-5] [Citation(s) in RCA: 20] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/25/2021] [Revised: 02/28/2022] [Accepted: 03/17/2022] [Indexed: 06/14/2023]
Abstract
BACKGROUND Leukaemias comprise a heterogenous group of haematological malignancies. In CONCORD-3, we analysed data for children (aged 0-14 years) and adults (aged 15-99 years) diagnosed with a haematological malignancy during 2000-14 in 61 countries. Here, we aimed to examine worldwide trends in survival from leukaemia, by age and morphology, in young patients (aged 0-24 years). METHODS We analysed data from 258 population-based cancer registries in 61 countries participating in CONCORD-3 that submitted data on patients diagnosed with leukaemia. We grouped patients by age as children (0-14 years), adolescents (15-19 years), and young adults (20-24 years). We categorised leukaemia subtypes according to the International Classification of Childhood Cancer (ICCC-3), updated with International Classification of Diseases for Oncology, third edition (ICD-O-3) codes. We estimated 5-year net survival by age and morphology, with 95% CIs, using the non-parametric Pohar-Perme estimator. To control for background mortality, we used life tables by country or region, single year of age, single calendar year and sex, and, where possible, by race or ethnicity. All-age survival estimates were standardised to the marginal distribution of young people with leukaemia included in the analysis. FINDINGS 164 563 young people were included in this analysis: 121 328 (73·7%) children, 22 963 (14·0%) adolescents, and 20 272 (12·3%) young adults. In 2010-14, the most common subtypes were lymphoid leukaemia (28 205 [68·2%] patients) and acute myeloid leukaemia (7863 [19·0%] patients). Age-standardised 5-year net survival in children, adolescents, and young adults for all leukaemias combined during 2010-14 varied widely, ranging from 46% in Mexico to more than 85% in Canada, Cyprus, Belgium, Denmark, Finland, and Australia. Individuals with lymphoid leukaemia had better age-standardised survival (from 43% in Ecuador to ≥80% in parts of Europe, North America, Oceania, and Asia) than those with acute myeloid leukaemia (from 32% in Peru to ≥70% in most high-income countries in Europe, North America, and Oceania). Throughout 2000-14, survival from all leukaemias combined remained consistently higher for children than adolescents and young adults, and minimal improvement was seen for adolescents and young adults in most countries. INTERPRETATION This study offers the first worldwide picture of population-based survival from leukaemia in children, adolescents, and young adults. Adolescents and young adults diagnosed with leukaemia continue to have lower survival than children. Trends in survival from leukaemia for adolescents and young adults are important indicators of the quality of cancer management in this age group.

Disparities in economic burden for children with leukemia insured by resident basic medical insurance: evidence from real-world data 2015–2019 in Guangdong, China. BMC Health Serv Res 2022; 22:229. [PMID: 35183172 PMCID: PMC8858506 DOI: 10.1186/s12913-022-07564-8] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Accepted: 01/31/2022] [Indexed: 12/04/2022] Open
Abstract
Background Pediatric leukemia is the most prevalent childhood cancer in China and incurs heavy economic burden to patients without sufficient insurance protection. Although all Chinese children are obliged to enroll in the national insurance scheme, “Resident Basic Medical Insurance (RBMI)”, the protection may vary among patient subgroups. This study is designed to measure the disparities in economic burden for patients with leukemia under RBMI protection and explore the influencing factors. Methods The included patients were aged ≤ 15 and diagnosed with acute lymphoblastic leukemia (ALL) or acute myeloid leukemia (AML, with/without transplantation). They all completed treatment course consecutively in Nanfang Hospital and Zhujiang Hospital from Jan.1, 2015, to Dec.30, 2019, in Guangzhou, China. Their inpatient treatment and insurance settlement data were drawn from the Hospital Information System (HIS) and Insurance Settlement System (ISS). A total of 765 consecutive patients and 14,477 inpatient medical records were included and analyzed. Their insurance status (6 subtypes), economic burden [total cost, out-of-pocket cost (OOP), reimbursement, reimbursement rate (RR)], and cost structures (operation/procedure, blood products, drug, simple treatment) were calculated respectively. Non-normally distributed costs were reported as the median and interquartile range (IQR). Wilcoxon test was used for univariate tests and generalized linear model with log link was used to explore the influencing factors. Results The insured patients who were treated in the location of insurance with instant reimbursement reported the highest total cost and reimbursement, while those who seek medical care cross-province with no instant reimbursement reported the lowest total cost and highest OOP payment. In terms of annual change, the total cost of children with leukemia decreased from 2015–2019 with stably increasing reimbursement rate. Blood products and drugs were the major components of total cost, but they decreased annually. Patients who received transplantation and treated across provinces were with a higher economic burden. Conclusion The economic burden for children with leukemia decreased overtime under the protection of RBMI, but disparities exist among subtypes. The payer-provider contract on instant reimbursement and drug cost control are effective measures for insurance administrators to curb the economic burdens of pediatric leukemia treatment.

Abstract
Background The patterns of leukemia burden have dramatically changed in recent years. This study aimed to estimate the global trends of leukemia‐related death and disability‐adjusted life‐years (DALYs) from 1990 to 2017. Methods The data was acquired from the latest version of the Global Burden of Disease (GBD) study. Estimated annual percentage changes (EAPCs) were calculated to estimate the trend of age‐standardized rate (ASR) of death and DALYs due to leukemia and its main subtypes from 1990 to 2017. Results Globally, the numbers of death and DALYs due to leukemia were 347.58 × 103 (95% uncertainty interval [UI] = 317.26 × 103‐364.88 × 103) and 11975.35 × 103 (95% UI = 10749.15 × 103‐12793.58 × 103) in 2017, with a 31.22% and 0.03% increase in absolute numbers from 1990 to 2017, respectively. Both of their ASR showed decreasing trends from 1990 to 2017 with the EAPCs being −1.04 (95% confidence interval [CI] = (−1.10‐−0.99) and −1.52 (95% CI = −1.59‐−1.44), respectively. Globally, the most pronounced decreasing trend of death and DALYs occurred in chronic myeloid leukemia with EAPCs of −2.76 (95% CI = −2.88‐−2.64) and −2.84 (95% CI = −2.97‐−2.70), respectively, while the trend increased in acute myeloid leukemia. The death and DALYs of leukemia decreased in most areas and countries with high socio‐demographic index (SDI) including Bahrain, Finland, and Australia. Conclusions The disease burden of death and DALYs due to leukemia decreased globally, and for most regions and countries from 1990 to 2017. However, the leukemia burden is still a substantial challenge globally and required adequate and affordable medical resources to improve the survival and quality of life of leukemia patients.

Abstract
Central nervous system (CNS) tumors represent the most deadly cancer in pediatric age group. In China, thousands of children are diagnosed with CNS tumors every year. Despite the improving socioeconomic status and availability of medical expertise within the country, unique challenges remain for the delivery of pediatric neuro-oncology service. In this review, we discuss the existing hurdles for improving the outcome of children with CNS tumors in China. Need for precise disease burden estimation, lack of intra- and inter-hospital collaborative networks, high probability of treatment abandonment, along with financial toxicities from treatment represent the key challenges that Chinese healthcare providers encounter. The tremendous opportunities for advancing the status of pediatric neuro-oncology care in and beyond the country are explored.

Abstract
This study evaluated the long-term therapeutic effect and prognostic factors of acute lymphoblastic leukemia (ALL) in 100 young Chinese children (<2 years old) who were enrolled in the Shanghai Children's Medical Center (SCMC)-ALL-2009 study in five pediatric hematological disease centers based on collaboration. The 5-year and 10-year event-free survivals (EFS) were 74.7 ± 3.2% and 73.3 ± 3.4%. The 10-year EFS rates for low risk, intermediate-risk, and high-risk patients were 81.9 ± 5.0%, 71.3 ± 4.3%, and 22.2 ± 13.9%, respectively. Relapse occurred in 19 patients. MRD results on day 55, good or poor response to prednisolone, and age at diagnosis were shown to have important prognostic and therapeutic implications. Compared with the SCMC-ALL-2005 protocol, showed that the 10-year-EFS and 10-year-overall survival of the SCMC-ALL-2009 protocol were better than that of the -2005 protocol. Notably, the intermediate-risk group was improved after the chemotherapy intensity was strengthened.

Abstract
Background B cell acute lymphoblastic leukemia (B-ALL) is the most common type of ALL. This study aimed to explore risk factors for relapse of childhood B-ALL. Material/Methods Total of 102 pediatric B-ALL patients were included in this study. B-ALL patients were divided into a relapse group and a non-relapse group. Chemotherapy-induced agranulocytosis time, fusion gene, and minimal residual disease (MRD) were assessed. White blood cell (WBC) count in peripheral blood and risk stratification were evaluated in newly-diagnosed patients. Kaplan-Meier plots were used to evaluate the correlation between risk factors and relapse rates. Multivariate analysis was performed with Cox proportional hazard model to estimate relative risk (RR), 95% confidence interval (95% CI), and hazard ratio (HR). Finally, 99 cases of B-ALL were included in this study. Results There were significant differences between the relapse group and the non-relapse group in age (p=0.004), chemotherapy-induced agranulocytopenia (p=0.001), WBC count in peripheral blood of newly diagnosed patients (p=0.016), risk stratification (p=0.000), and MRD at 12th week (p=0.007). Age over 10 years, high-risk stratification, long period of agranulocytopenia, higher WBC counts, and MRD more than 10−4 were correlated with higher B-ALL relapse rate (p<0.05). Multivariate analysis showed significantly higher relapse rates for age ≥10 years, high-risk stratification, and MRD at 12th week >10−4, with RR (95% CI) of 4.001 (1.005–15.930), 4.964 (1.050–23.456), and 4.646 (1.383–15.614), respectively. Conclusions Agranulocytopenia ≤7 days, peripheral blood WBC >100×109/L, and MRD at 33rd day >10−4 were associated with B-ALL relapse. Age ≥10 years, high-risk stratification, and MRD at 12th week >10−4 were independent risk factors for relapse.

Treatment abandonment in childhood acute lymphoblastic leukaemia in China: a retrospective cohort study of the Chinese Children's Cancer Group. Arch Dis Child 2019; 104:522-529. [PMID: 30705079 DOI: 10.1136/archdischild-2018-316181] [Citation(s) in RCA: 41] [Impact Index Per Article: 8.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2018] [Revised: 12/12/2018] [Accepted: 12/13/2018] [Indexed: 11/04/2022]
Abstract
OBJECTIVES Before 2003, most children with acute lymphoblastic leukaemia (ALL) abandoned treatment, with only approximately 30% treated in China. With the development of national insurance for underprivileged patients, we assessed the current frequency and causes of treatment abandonment among patients with ALL who were enrolled in the Chinese Children's Cancer Group ALL protocol between 2015 and 2016. METHODS Demographic, clinical and laboratory data on patients who abandoned treatment, as well as economic and sociocultural data of their families were collected and analysed. General health-related statistics were retrieved from publicly accessible databanks maintained by the Chinese government. RESULTS At a median follow-up of 119 weeks, 83 (3.1%, 95% CI 2.5% to 3.8%) of the 2641 patients abandoned treatment. Factors independently associated with abandonment included standard/high-risk ALL (OR 2.62, 95% CI 1.43 to 4.77), presence of minimal residual disease at the end of remission induction (OR 3.57, 95% CI 1.90 to 6.74) and low-income economic region (OR 3.7, 95% CI 1.89 to 7.05). According to the family members, economic constraints (50.6%, p=0.0001) were the main reason for treatment abandonment, followed by the belief of incurability, severe side effects and concern over late complications. CONCLUSIONS The rate of ALL treatment abandonment has been greatly reduced in China. Standard/high-risk ALL, residence in a low-income region and economic difficulties were associated with treatment abandonment. CLINICAL TRIAL REGISTRATION NUMBER ChiCTR-IPR-14005706, pre-results.

Abstract
Acute lymphoblastic leukemia (ALL) is the most common malignancy among children. The trial Chinese Children Leukemia Group (CCLG)-ALL 2008 was a prospective clinical trial designed to improve treatment outcome of childhood ALL through the first nation-wide collaborative study in China. Totally 2231 patients were recruited from ten tertiary hospitals in eight cities. The patients were stratified according to clinical-biological characteristics and early treatment response. Standard risk (SR) and intermediate risk (IR) groups were treated with a modified BFM based protocol, and there was 25%-50% dose reduction during intensification phases in the SR group. Patients in high risk (HR) group received a more intensive maintenance treatment. Minimal residual disease (MRD) monitoring with treatment adjustment was performed in two hospitals (the MRD group). Complete remission (CR) was achieved in 2100 patients (94.1%). At five years, the estimate for overall survival (OS) and event-free survival (EFS) of the whole group was 85.3% and 79.9%, respectively. The cumulative incidence of relapse (CIR) was 15.3% at five years. The OS, EFS and CIR for the SR group were 91.5%, 87.9%, and 9.7%, respectively. The outcome of the MRD group is better than the non-MRD group (5y-EFS: 82.4% vs 78.3%, P = .038; 5y-CIR: 10.7% vs 18.0%, P < .001). Our results demonstrated that the large-scale multicenter trial for pediatric ALL was feasible in China. Dose reduction in the SR group could achieve high EFS. MRD-based risk stratification might improve the treatment outcome for childhood ALL.

Abstract
BACKGROUND Treatment abandonment (TxA) is a primary cause of therapy failure in children with cancer in low-/middle-income countries. We explored the absence of social support network (SSN), among other predictive factors, and TxA in children with cancer in Cali, Colombia. PROCEDURE In this prospective cohort study, we included children diagnosed with cancer at a public university hospital. A social worker and a psychologist administered semistructured questionnaires to patients' caregivers. We extracted information from the questionnaires about social, economic, and psychological conditions of the patients' families. Outcomes were death, relapse, and TxA. Failure either to start or to continue the planned course of curative treatment for 4 weeks or more was defined as TxA. We identified events with Cali's childhood cancer outcomes surveillance system (VIGICANCER). We adjusted the hazard ratios (HRs) for potential confounders using multivariate Cox regression analyses. RESULTS Among 188 patients diagnosed from January 2011 to June 2013, 99 interviews were conducted. Median age was 5 years old (range: 0.3, 14.9), 53% were male, 17% were of Colombian-Indian ethnicity, and 68% lived in rural areas. The 2-year cumulative incidence of TxA was 21% (95% confidence interval [CI]: 13, 35) and the annual proportion was 14%. The adjusted HR for the absence of SSN was 4.9 (95% CI: 1.6, 15.3). CONCLUSIONS We found a strong association between the absence of SSN and TxA that was independent of other covariates, including surrogate measures of wealth. Our findings highlight the imperative understanding of social ties and support surrounding children's families for planning strategies to prevent TxA.

Abstract
Partnerships between medical institutions in high-income countries (HICs) and low- to mid-income countries (LMICs) have succeeded in initiating and expanding pediatric cancer control efforts. The long-term goal is consistently a sustainable national pediatric cancer program. Here, we review the elements required for successful implementation, development, and long-term sustainability of pediatric cancer programs in LMICs that first arise as partnerships with institutions in HICs. Although plans must be adapted to each country's resources, certain components are unfailingly necessary. First, an essential step is provision of treatment regardless of ability to pay. Second, financial support for program development and long-term sustainability must be sought from sources both international and local, public and private. A local leader, typically a well-trained pediatric oncologist who devotes full-time effort to the project, should direct medical care and collaborate with hospital, governmental, and community leadership and international agencies. Third, nurses must be trained in pediatric cancer care and allowed to practice this specialty full-time. It is also essential to develop a grassroots organization, such as a foundation, dedicated solely to pediatric oncology. Its members must be trained and educated to provide pediatric cancer advocacy, fundraising, and (in concert with government) program sustainability. Finally, a project mentor in the HIC is crucial and should explore the possibility of collaborative research in the LMIC, which may offer significant opportunities. Relationships between the partnership's leaders and influential individuals in the community, hospital, grassroots foundation, and government will lay the foundation for productive collaboration and a sustainable pediatric oncology program.

Abstract
Marjolin's ulcers, which are epidermoid carcinomas arising on non-healing scar tissue, may be of various pathological types, including squamous cell carcinoma. The pathogenesis of squamous cell carcinoma arising in an ulcer differs from that of the primary cutaneous squamous cell carcinoma. This squamous cell carcinoma is aggressive in nature, and has a high rate of metastasis. Between January 2001 and September 2013, 51 patients with Marjolin's ulcers were admitted to the Departments of Plastic Surgery of the Affiliated Foshan Hospital and the Second Affiliated Hospital of Sun Yat-sen University. The ulcers included 43 cases of squamous cell carcinoma, six of melanoma, one of basal cell carcinoma and one of epithelioid sarcoma. The clinical data of these patients were retrospectively analyzed. Patients were followed until mortality. Among the patients with squamous cell carcinoma, 30.23% exhibited sentinel lymph node metastasis and 11.63% had distant metastasis. Among the patients with melanoma, 66.67% had sentinel lymph node metastasis and 33.33% had distant metastasis. Sentinel lymph node metastasis was successfully detected in 11 patients with Marjolin's ulcer using 18F-fluorodeoxyglucose positron emission tomography-computed tomography and B-mode ultrasound guided biopsy. Squamous cell carcinoma was often treated by extended resection and skin grafting or skin flap repair. Patients with deep, aggressive squamous cell carcinoma of an extremity and sentinel lymph node metastasis underwent amputation and lymph node dissection. This treatment was also used for melanoma type Marjolin's ulcers.
