The 26th World Conference on Lung Cancer (WCLC) was held in Barcelona during September 6-9, 2025. As the world's largest and most influential academic meeting in the field of lung cancer, this year's congress unveiled long-term follow-up data from several pivotal studies and significant advances in novel therapeutic strategies. In the realm of targeted therapy, a next-generation combination strategy has been established as the new standard of care for the first-line treatment of patients with advanced epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC), demonstrating a significant improvement in overall survival. In immunotherapy, novel combination regimens have not only addressed the therapeutic challenge of acquired resistance to EGFR targeted therapies, but also shown clear long-term survival benefits in both the perioperative and locally advanced settings. These findings pave the way for shifting the treatment paradigm to earlier stages for patients with NSCLC. Antibody-drug conjugates have made remarkable strides in this field. They have shown outstanding efficacy in patients with specific resistance mutations and those with brain metastases, and have also demonstrated immense potential in treating patients with HER2-aberrant lung cancer and broader NSCLC populations. This offers new therapeutic options for patients with refractory lung cancer.However, significant challenges remain, including the heterogeneity of resistance mechanisms, the selection of optimal treatment regimens, and management strategies for special populations. Future research should focus on identifying novel precision biomarkers and optimizing therapeutic strategies to ultimately improve clinical outcomes for all patients with lung cancer.

The 2025 European Lung Cancer Congress (ELCC) convened in Paris, France, centering on the optimization and innovation of immunotherapy for non-small cell lung cancer (NSCLC). Key topics at the congress included the application strategies for perioperative immunotherapy, breakthroughs in combination therapy models for advanced NSCLC, and the emerging roles of biomarkers in predicting diverse treatment outcomes. This paper integrates data from several key pivotal studies to systematically analyze the clinical value of neoadjuvant therapy within the perioperative setting, the potential of targeted combination regimens, and the challenges of managing drug resistance, thus offering new directions for clinical practice.

Objective·To evaluate the applicability of dual-unit cantilever restorations supported by a single narrow-diameter implant for consecutive missing teeth in the anterior mandibular region.Methods·A simplified mandibular anterior jaw model and a dual-unit cantilever model supported by a single narrow-diameter implant were constructed.The dimensions of the mandibular anterior bone block were set to 20 mm(length),5 mm(width),and 15 mm(height).The narrow-diameter implant used was the Axiom 2.8 two-stage implant,2.8 mm× 10 mm,paired with a 2.5 mm straight abutment.Based on calculations,the edentulous gap ranged from 5.8 mm to 11.6 mm,leading to the creation of seven crown models with mesiodistal widths of 5.8,6.8,7.8,8.8,9.8,10.8,and 11.8 mm.The implant,crowns,and jaw model were assembled using Siemens Nx 12.0 software,and the data were imported into Ansys Workbench 18.0 for finite element analysis.A vertical load of 100 N and a 30° oblique load were applied to simulate occlusal forces.The Von-Mises stress on the implants,as well as the maximum compressive and tensile stresses in the cortical bone and the maximum tensile stress in the cancellous bone,was analyzed to investigate stress distribution under varying cantilever lengths.Results·The implant neck region exhibited the highest stress concentration.As the cantilever length increased,the peak Von-Mises stress on the implants,the maximum tensile stress in the cortical and cancellous bones,and the maximum compressive stress in the cortical bones all increased progressively.However,all stress values remained within physiological limits.The peak Von-Mises stress ranged from 141.52 MPa to 707.17 MPa,below the implant's ultimate tensile strength of 930 MPa.The maximum tensile stress in the cortical bones(with a peak of 60.82 MPa in the 11.8 mm group)was below the cortical bone's tensile strength limit of 100-130 MPa.The maximum compressive stress in the cortical bone(with an absolute maximum value of 129.39 MPa in the 11.8 mm group)was below the cortical bone's compressive strength limit of 170 to 190 MPa(absolute values).The maximum tensile stress in the cancellous bone ranged from 0.84 MPa to 4.70 MPa,which was below or close to its ultimate tensile strength of 2-5 MPa.Conclusion·Dual-unit cantilever restorations supported by a single narrow-diameter implant may represent a viable treatment option for consecutive missing teeth in the anterior mandibular region.

Objective To explore the effect of Huangqi Danzhi Shenmai Decoction in treatment of coronary atherosclerosis patients with qi deficiency and blood stasis syndrome and its influence on the levels of serum malondialdehyde(MDA),superoxide dismutase(SOD),tumor necrosis factor-α(TNF-α),and interleukin-1 β(IL-1β).Methods A total of 120 patients with coronary atheroscle-rosis were selected and randomly divided into control group(conventional treatment+simvastatin)and observation group(conventional treatment+Huangqi Danzhi Shenmai Decoction)by random number table method,with 60 cases in each group.The clinical efficacy of the two groups was evalua-ted.The changes in traditional Chinese medicine(TCM)syndrome scores,blood lipids,inflammatory factors,and oxidative stress indicators before and after treatment were recorded for both groups.Re-sults The total effective rate in the observation group was higher than that in the control group(P＜0.05).After treatment,the TCM syndrome scores in the observation group were lower than those in the control group(P＜0.05).The improvement in blood lipid indicators was more pronounced in the observation group compared to the control group(P＜0.05).The serum levels of TNF-α,IL-1 β,and MDA in the observation group were lower than those in the control group,while the serum levels of SOD and glutathione peroxidase(GSH-PX)were higher than those in the control group,with statis-tically significant differences(P＜0.05).No severe adverse reactions occurred in either group dur-ing the treatment period.Conclusion Huangqi Danzhi Shenmai Decoction has a good clinical effi-cacy in treating coronary atherosclerosis with qi deficiency and blood stasis syndrome,and can im-prove the oxidative stress status,reduce inflammatory responses,and regulate blood lipid levels in patients,so it is worthy of clinical promotion and use.

Objective To investigate the inhibitory effect of morin on the cell cycle progression and prolif-eration ability of lung adenocarcinoma cells by regulating the transforming growth factor β1(TGF-β1)/Smads signaling pathway.Methods Human lung adenocarcinoma cell line A549 was used for in vitro experiments.Different concentrations of morin(0,30,90,150 μg/mL)were used to treat human lung adenocarcinoma cell line A549.Cell survival rate was detected by CCK-8 method,cell cycle distribution was detected by Hoechst 33342 staining method,cell proliferation ability was detected by clone formation assay,cell invasion ability was detected by Transwell invasion assay,cell apoptosis was detected by TUNEL staining method,and the expres-sion levels of TGF-β1/Smads signaling pathway related proteins were analyzed by Western blot.Results CCK-8 experimental results showed that the survival rate of A549 cells in the morin-treated group significantly decreased with the increase in morin concentration(P＜0.05).The results of Hoechst 33342 staining showed that the proportion of G1 phase cells in the morin-treated group significantly increased,and the proportion of S phase and G2/M phase cells significantly decreased(P＜0.05).The results of the colony formation assay showed that the number of colonies formed in the morin-treated group was significantly less than that in the control group,and the colony formation rates in the 90 μg/mL and 150 μg/mL groups were reduced by approximately 50％and 70％respectively(P＜0.05).Transwell invasion assay results showed that the number of invasive cells in the morin-treated group was significantly reduced(P＜0.05).TUNEL staining results showed that the proportion of apoptotic cells in the morin-treated group significantly increased(P＜0.05).Western blot results showed that the expression levels of TGF-β1 and p-Smad2/3 in the morin-treated group were significantly reduced(P＜0.05),and the expression level of Smad7 was significantly in-creased(P＜0.05).Conclusion Morin blocks A549 cells in the G1 phase by regulating the TGF-β1/Smads signaling pathway,thereby inhibiting cell proliferation,reducing cell invasion ability,and inducing cell apopto-sis.This indicates that morin has potential application value in the treatment of lung adenocarcinoma.

Objective To discover the mechanism by which miR-1287-5p affects the sensitivity of human esophageal cancer cell line KYSE30 to paclitaxel.Methods KYSE30 cells were divided into control group,group of transfected with miR-1287-5p mimic and inhibitor groups.RT-qPCR was used to detect the transfection rate.A paclitaxel-resistant cell line was established and cell viability and half inhibitory concentration(IC50)were detected by CCK-8 assay.The scratch test,Transwell chamber test and TUNEL method were used to evaluate the migration,invasion and apoptosis of cells.Western blot and immunocytochemistry(ICC)were used to detect the expression and localization of Akt and GSK-3β in cells.Results The expression level of miR-1287-5p in the miR-1287-5p mimic group was significantly higher than that in the miR-NC group and control group(P＜0.05),while the ex-pression level of the miR-1287-5p inhibitor group was significantly lower than that in miR-NC group and control group(P＜0.05).The cell survival rate of the miR-1287-5p mimic group was higher than that of the miR-NC group and the miR-1287-5p inhibitor group(P＜0.05).The cell migration rate and number of invasive cells in the miR-1287-5p mimic group were higher than those of the miR-NC group(P＜0.05),and the apoptosis rate was lower than that of the miR-NC group(P＜0.05).While in miR-1287-5p,the cell migration rate was lower and invasive cells were less in the inhibitor group and the apoptosis rate was increased as compared to the miR-NC group(P＜0.05).The expression of Akt and GSK-3β in the miR-1287-5p mimic group was significantly increased than in the miR-NC group(P＜0.05),while the expression in the miR-1287-5p inhibitor group was significantly inhibited than in miR-NC group(P＜0.05).Conclusions Up-regulation of miR-1287-5p can promote the migration and invasion of paclitaxel-resistant cell lines,inhibit cell apoptosis and thereby promote the development of paclitaxel resistance.

Objective To analyze the relationship between fragmented QRS(fQRS)and microalbuminuria(MAU)and serum uric acid(SUA)in patients with type 2 diabetes mellitus(T2DM).Methods From October 2022 to June 2023,245 T2DM patients diagnosed by The Department of Endocrinology,Jinhua Hospital Affiliated to Zhejiang University School of Medicine were selected and divided into fQRS group(fQRS,n=111)and T2DM group(n=134)according to ECG results.The general data,biochemical indexes,left ventricular end-diastolic diameter(LVEDd),left ventricular end-systolic diameter(LVESd),interventricular septum(IVS),left ventricular posterior wall(LVPW),left ventricular ejection fraction(LVEF),left atrial diameter(LAd),peak value ratio of mitral orifice blood flow velocity in early and late diastole(E/A)and mitral orifice blood flow velocity in early diastole were compared between the two groups.Pearson correlation analysis was used to analyze the correlation between fQRS wave and other indexes in T2DM patients,and Logistic regression analysis was used to analyze the influencing factors of fQRS.Results The prevalence rates of UACR,SUA,HbA1c and MAU in fQRS group were higher than in T2DM group(P＜0.05 or P＜0.01).LVEDd,LAd,E,E/e'and E/A>1.5 in QRS group were higher than in T2DM group(P＜0.05 or P＜0.01).Pearson correlation analysis showed that fQRS wave was positively correlated with smoking history,BMI,HbA1c,UACR,MAU,SUA,LVEDd,LAd,E/A and E/e'(P＜0.05).Logistic regression analysis showed that MAU was the influencing factor of fQRS wave in T2DM patients.Conclusions The fQRS in ECG in patients with T2DM is associated with MAU and SUA and may be an important evidence of myocardial fibrosis associated with subclinical cardiac diastolic dysfunction.

Objective:To establish the Chinese version of (strength, assistance with walking, rise from a chair, climb stairs and falls, SARC-F) scale using the standardized methods and to validate the reliability and validity for sarcopenia screening among elderly population.Methods:Following the recommended procedure by World Health Organization and European Union Geriatric Medicine Society Sarcopenia Special Interest Group, the translation process included forward translation, expert panel, back-translation, pre-testing and cognitive interviewing to generate the final version. In the pilot study, the test-retest reliability, inter-rater reliability, and internal consistency of the Chinese version of SARC-F scale were assessed. In the diagnostic test for clinical validation, the participants were consecutively recruited from communities and hospitals in Beijing and Tianjin between December 2021 and October 2022. The scale administration, anthropometry, and body composition measurement were conducted by trained investigators. Participants with the SARC-F score ≥ 4 were considered at risk of sarcopenia. Diagnostic tests and receiver operating characteristic curve analysis were performed against the definitions of sarcopenia according to European Working Group on Sarcopenia in Older People (EWGSOP2) and Asian Working Group for Sarcopenia (AWGS2019), and the sensitivity, specificity, positive predictive value, negative predictive value and the area under curve were displayed.Results:The Chinese version of SARC-F scale was approved by the author that the translation has expressed the original meaning correctly. The Chinese version of SARC-F had good test-retest reliability (ICC = 0.914), inter-rater reliability ( r = 0.726), and internal consistency ( α = 0.729). There were altogether 1 882 participants included in the clinical validation. According to the diagnostic criteria of EWGSOP2 and AWGS2019, the Chinese version of SARC-F scale had low sensitivity (13.6% and 16.0%) and positive predictive value (44.6% and 35.4%), high specificity (95.1% and 94.7%) and negative predictive value (79.0% and 86.2%), and moderate AUC of 0.619 and 0.616 (all P < 0.001) for sarcopenia screening. Conclusions:The Chinese version of SARC-F scale was of good reliability and validity. The application of SARC-F in the primary healthcare settings would contribute to the early diagnosis of sarcopenia.

【Objective】 To learn the production efficient of platelet components among prefecture-level blood stations in China, to provide supporting data for those blood stations to optimize the production mode of platelet components and continuously improve production efficiency and supply capacity. 【Methods】 The data from 2017 to 2020 was obtained from 24 prefecture-level blood stations who were the members of the practice comparison network for blood institutes in China. The collection units of apheresis platelets, the number of dual-collections of apheresis platelets and plasma, the average apheresis units of one platelet apheresis procedure, the discarded rate of apheresis platelets, the amount of expired apheresis platelets and the amount of apheresis platelets issued were collected. For concentrated platelets, the prepared amount of platelet concentrates and the amount of expired platelet concentrates were collected; both the quantity of qualified and issued concentrated platelets were submitted for statistical analysis.The total output and efficiency of platelet components were calculated based on the collected data. 【Results】 The average annual growth rate of apheresis platelets collection in 24 prefecture-level blood stations was 12.23%, accounting for 99.80% of the total platelet output; the average collection unit of one platelets apheresis procedure was 1.75; from 2019 to 2020, only 5 blood stations performed dual-collection of platelet and plasma during one apheresis procedure; the discarded rate of apheresis platelets was 0.28%, of which 0.007% was due to expiration. A total of 1 621.2 therapeutic units of concentrated platelets were prepared, and 13.03% of them was discarded due to the expiration. The production efficiency of platelet components was 97.56%, of which the production efficiency of apheresis platelets was 97.61% and the production efficiency of concentrated platelets was 74.43%. 【Conclusion】 There are large regional differences in the supply capacity of platelet components in prefecture-level blood stations. Apheresis platelets are the main resource of platelet components product, and the collection capacity is increasing over the years with the characteristics of high production efficiency and low expiration scrapping rate. However, the preparation of concentrated platelets are still limited with relatively low production and high expiration discarded rate.
