Health economics evidence plays an important role in linking clinical value evidence with health resource allocation decisions in the development of clinical practice guidelines. It can not only effectively balance clinical effectiveness and economic feasibility but also avoid forming "idealized" recommendations that are detached from the affordability of the healthcare system or the burden-bearing capacity of patients. To promote guideline developers to use health economics evidence more standardizedly and fully, this paper conducts an in-depth analysis of the current application status, existing challenges, access channels, and application processes of health economics evidence in current guidelines, and on this basis, puts forward considerations and suggestions for strengthening and standardizing the application of health economics evidence in China's clinical practice guidelines.

Objective To address the national requirements for high-quality development of public hospitals issued by the National Health Commission(NHC),this study establishes a knowledge-value-oriented performance management system tailored to dental specialty characteristics,aiming to synergistically enhance disciplinary advancement and operational efficiency.Methods Guided by policies such as Guidelines on Strengthening Operational Management in Public Hospitals,we integrated resources in oral and maxillofacial surgery through data-driven decision-making and multidimensional investigations.A"2-3-3"performance manage-ment model was developed,featuring dual objectives(public welfare and economic efficiency),a three-tier allocation mechanism(hospital-department-individual),and triple support strategies(key disciplines,young talents,and under-resourced projects).Im-plementation involved organizational restructuring,business-finance integration,and digital transformation.Results Post-reform outcomes demonstrated a 14％year-on-year increase in outpatient volume and a 9％growth in bed-to-surgery ratio.Both medical quality indicators and revenue and expenditure structures were optimized,achieving better equilibrium between public welfare and economic sustainability.Conclusion This model replaces the egalitarian distribution approach with a value-driven incentive mech-anism,effectively promoting disciplinary specialization and talent engagement.It provides a replicable framework for performance reform in dental specialty hospitals,aligning with the NHC's policy orientation on refined public hospital management.

Objective:To explore the pathogenesis,clinical features,treatment strategies,and prognosis of pediatric lymphoepithelioma-like carcinoma(LELC).Methods:A retrospective analysis was conducted on the clinical data of patients with LELC aged<18 years,treated at Sun Yat-sen University Cancer Center from March 2008 to June 2023.Results:A total of 19 children and adolescents were included in the analys-is,comprising 10 males(52.6%)and 9 females(47.4%),with a median age of 12.9(4.3-17.0)years.Fourteen patients(73.7%)lived in Guangdong province,with the remainder scattered across other regions.Primary LELC sites were the mediastinum(11 cases,57.9%),parot-id glands(4 cases,21%),neck(1 case,5.3%),lungs(1 case,5.3%),salivary glands(1 case,5.3%),and submandibular glands(1 case,5.3%).Among these,15 patients(78.9%)had at least one distant metastasis at initial diagnosis,with common metastasis sites being cervical lymph nodes.Multivariate Cox regression analysis identified tumor volume≥801 cm3 as an independent adverse prognostic factor of poor overall survival(OS)(P<0.01).The 2-year OS and progression-free survival(PFS)rates were 84.2%and 57.9%,respectively.The 2-year OS for pa-tients who underwent surgery,chemotherapy,and radiotherapy was 100%,compared with 25%for those who received only partial treat-ment(P=0.007).The 2-year PFS rate was significantly higher in patients receiving first-line combination therapy with programmed death-1(PD-1)antibodies(100%)compared with those not treated with PD-1 antibodies(38.5%)(P=0.020).For patients with tumor volume≥801 cm3,the 2-year OS was 40.0%,whereas for those with a tumor volume<801 cm3,the 2-year OS was 100%(P<0.001).The 2-year OS for pa-tients who underwent radiotherapy was 100%,while it was 0 for those who did not receive radiotherapy(P<0.001).Conclusions:Pediatric LELC exhibits a relatively favorable prognosis with multidisciplinary treatment,including surgery,chemotherapy,and radiotherapy.The com-bined use of PD-1 antibodies at the time of initial diagnosis could offer potential benefits and warrants further exploration.

Objective:To analyze the clinical features and prognosis of acute B lymphoblastic leukemia (B-ALL) children carrying a TCF3: : PBX1 fusion gene and to evaluate the prognostic value of this gene.Methods:Retrospective cohort study.A total of 2 164 B-ALL children aged 0-18 years diagnosed and treated at 19 pediatric centers from October 2016 to June 2022 were enrolled.They were divided into the positive group and the negative group according to whether they carried a TCF3: : PBX1 fusion gene.The clinical characteristics, treatment response, adverse reactions, and prognosis of the 2 groups of patients were analyzed.The rank sum and Kruskal-Wallis tests were used to compare two and more than two groups of numerical variables, respectively.Fisher′s exact test was used to compare categorical variables.Results:Among the 2 164 patients, 116 (5.4%) were TCF3: : PBX1 positive, of which 70 patients were female, accounting for 60.3%.There were 840 female patients in the TCF3: : PBX1-negative group, accounting for 41.0%.There was a significant difference in the ratio of females between the TCF3: : PBX1-positive and TCF3: : PBX1-negative groups ( P<0.001).No significant difference was observed in age of onset between the two groups( P>0.05).The proportion of bone marrow naive cells [54.00 (14.00, 76.50)% vs.29.00 (3.00, 68.00)%], white blood cell counts [25.30 (10.46, 60.94)×10 9/L vs.9.03 (4.38, 30.73)×10 9/L] and hemoglobin counts [82.00(63.00, 101.00) g/L vs.74.00(60.00, 90.00) g/L] in the TCF3: : PBX1-positive group were significantly higher than those in the negative group at the onset (all P<0.05).In terms of treatment response, the proportion of peripheral blood naive cells on Day 8 in the TCF3: : PBX1-positive group was significantly higher than that in the negative group [2.00 (0, 9.00)% vs.0 (0, 2.00)%, P<0.001].The proportion of minimal residual disease <0.1% on Day 15 in the TCF3: : PBX1-positive group was significantly higher than that in the negative group ( P=0.038).There were no significant differences in cumulative recurrence rate, treatment-related mortality (TRM), and overall survival (OS) between the TCF3: : PBX1-positive group and TCF3: : PBX1-negative group (all P>0.05).The cumulative recurrence risk of TCF3: : PBX1-positive patients was 9.646 times higher than that of ETV6: : RUNX1-positive patients with better prognosis( HR=9.646, 95% CI: 1.026-90.700, P=0.047).There were no significant differences in TRM and OS between TCF3: : PBX1-positive and ETV6: : RUNX1-positive patients (all P>0.05).A significant enrichment of PAX5 mutations was detected in TCF3: : PBX1-positive patients.Among the 7 high-risk TCF3: : PBX1-positive patients in a single center, 4 patients had PAX5 mutations, and this proportion was significantly higher than that in other patients ( P<0.001). Conclusions:B-ALL children carrying a TCF3: : PBX1 fusion gene have a high remission rate and good long-term prognosis after intensive chemotherapy.It is suggesting that TCF3: : PBX1-positive B-ALL patients should be rated at intermediate risk to receive intensive chemotherapy.

Purpose: The risk stratification of pediatric anaplastic large cell lymphoma (ALCL) has not been standardized. In this study, new risk factors were included to establish a new risk stratification system for ALCL, and its feasibility in clinical practice was explored. Materials and Methods: On the basis of the non-Hodgkin’s lymphoma Berlin–Frankfurt–Munster 95 (NHL-BFM-95) protocol, patients with minimal disseminated disease (MDD), high-risk tumor site (multiple bone, skin, liver, and lung involvement), and small cell/lymphohistiocytic (SC/LH) pathological subtype were enrolled in risk stratification. Patients were treated with a modified NHL-BFM-95 protocol combined with an anaplastic lymphoma kinase inhibitor or vinblastine (VBL). Results: A total of 136 patients were enrolled in this study. The median age was 8.8 years. The 3-year event-free survival (EFS) and overall survival of the entire cohort were 77.7% (95% confidence interval [CI], 69.0% to 83.9%) and 92.3% (95% CI, 86.1% to 95.8%), respectively. The 3-year EFS rates of low-risk group (R1), intermediate-risk group (R2), and high-risk group (R3) patients were 100%, 89.5% (95% CI, 76.5% to 95.5%), and 67.9% (95% CI, 55.4% to 77.6%), respectively. The prognosis of patients with MDD (+), stage IV cancer, SC/LH lymphoma, and high-risk sites was poor, and the 3-year EFS rates were 45.3% (95% CI, 68.6% to 19.0%), 65.7% (95% CI, 47.6% to 78.9%), 55.7% (95% CI, 26.2% to 77.5%), and 70.7% (95% CI, 48.6% to 84.6%), respectively. At the end of follow-up, one of the five patients who received maintenance therapy with VBL relapsed, and seven patients receiving anaplastic lymphoma kinase inhibitor maintenance therapy did not experience relapse. Conclusion This study has confirmed the poor prognostic of MDD (+), high-risk site and SC/LH, but patients with SC/LH lymphoma and MDD (+) at diagnosis still need to receive better treatment (ClinicalTrials.gov number, NCT03971305).

Objective:Glucorticoid therapy has the potential to mitigate immunogical effect of naxitamab. Ketamine is an anesthetic medica-tion and cause weak or shallow breathing. This article is to analyze the effect of modified conditioning regimen with substitution re-mifentanil for ketamine and without glucorticoid therapy on adverse events associated with naxitamab. Methods:Clinical data with naxit-amab infusion under modified conditioning regimen in Sun Yat-sen University Cancer Center between June 2023 and June 2024 were re-trieved to analyze adverse events and risk factors. Results:Overall,seventeen patients underwent 201 infusions. The most frequent adverse events were as follows:neurological pain (all grades) 93.0％,hypertension 55.7％,hypotension 34.8％,respectively. Bronchospasm and hyp-oxia were seen in 3.0％ and 10.9％ infusions,respectively. Fever occurred less frequently in the second cycle of infusion. No patients suspen-ded infusion due to severe adverse event. Conclusions:The infusion of naxitamab is tolerable under the modified conditioning regimen and adverse event is less than expected and controllable.
