The 2025 American Society of Clinical Oncology (ASCO) Annual Meeting was held in Chicago. At the meeting, researches on the treatment of epidermal growth factor receptor (EGFR)-mutant non-small cell lung cancer (NSCLC) once again took the spotlight. Combination therapy strategies have demonstrated the potential to overcome resistance to EGFR tyrosine kinase inhibitor (EGFR-TKI) and prolong survival. Meanwhile, progress has also been made in individualized treatment strategies for young patients and those with fibrotic interstitial lung disease. However, the complexity of resistance mechanisms, special treatment considerations for different populations, and the impact of socioeconomic factors on treatment accessibility remain challenges in the field of EGFR-mutant NSCLC treatment. In the future, it is necessary to further explore more effective treatment regimens and expand the accessibility of precision medicine to maximize patient benefits.

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.

To effectively carry out community health education and prevention and control of chronic obstructive pulmonary disease(COPD),we conducted a questionnaire survey on the awareness of COPD knowledge among residents aged 40 and above in Jiading District of Shanghai by using two-stage sampling method.We included 1 783 permanent residents in 4 districts and collected 1 666 valid questionnaires.The awareness rates of COPD name,pulmonary function test and related knowledge were 15.9%,11.9%and 17.2%,respectively.For the main symptoms of COPD,the awareness rate of sputum was the lowest(65.2%),of shortness of breath and dyspnea was the highest(78.4%).For the risk factors,the awareness rate of severe respiratory tract infection in childhood was the lowest(67.3%),of smoking was the highest(86.8%).Multiple response analysis showed that mobile phones and computers accounted for the highest proportion of acquiring knowledge of COPD(66.7%).Multivariate logistic regression analysis showed that low educational level,low monthly income,engaged in production and manufacturing,never or less exercise,no use of indoor air improvement measures,no wearing of masks in public places and no vaccination of influenza vaccine per year were associated with lower awareness rate of COPD.The community should improve the way and ability of health science popularization,and carry out health education for key groups.

Objective:To explore the clinical characteristics and prognosis risk factors of aggressive NK-cell leukemia(ANKL).Methods:The clinical and laboratory data of 34 patients with ANKL and 15 patients with chronic lymphoproliferative disorders of NK cells(CLPD-NK)admitted to the First Affiliated Hospital of Zhengzhou University from September 2019 to December 2024 were retrospectively analyzed.The Kaplan-Meier method was used to calculate survival rates,and the Cox proportional hazards regression model was used to analyze prognostic factors.Results:Compared with CLPD-NK patients,ANKL patients had a younger median age of onset,a higher proportion patients with EBV-DNA≥500 copies/ml,hepatosplenomegaly and hemophagocytic syndrome.They also presented with a higher peak of fever,a shorter median survival time,lower WBC count,PLT count,ALB and Fib values,while having higher LDH,AST,TG,ferritin,CRP and PCT levels.There were statistically significant differences in the morphology and expression of HLA-DR,CD56,CD57,CD16 and CD158 on abnormall cells between ANKL patients and CLPD-NK patients.Multivariate survival analysis revealed that combined with asparaginase treatment could improve patients' survival,and CRP≥ 15 mg/L and Fib＜2.0 g/L were independent risk factors affecting the overall survival of patients with ANKL.Conclusion:The differences in clinical features and laboratory tests between patients with ANKL and CLPD-NK aid in the diagnosis of ANKL.CRP and Fib levels can be used to predict the prognosis of patients,and combined asparaginase therapy can enhance the overall survival of patients.

Lens injury is an important etiological factor in the reduction of visual function following ocular trauma.Currently, there are no clear standards for the classification of lens injury, and comprehensive diagnostic tools are lacking.This deficiency leads to numerous controversies and challenges in critical areas, such as diagnosis and preoperative evalution, timing of surgery, surgical strategy, and assessment of postoperative prognosis.Tomographic imaging technology, such as computed tomography, magnetic resonance imaging, optical coherence tomography, has introduced a new dimension to the evaluation of lens injury, which is crucial for assessing the transparency, texture, location, morphology, and integrity of the lens, as well as the zonules and nearby intraocular structures.However, the use of tomographic imaging technology is somewhat limited due to the limitations of relying on a single method.With the ongoing advancement of imaging technologies and the rapid development of big data and artificial intelligence, tomographic imaging will become an increasingly essential tool in the future management of lens injury.Our expert group reviewed the epidemiological characteristics and classification of lens injury and the major challenges currently faced in the diagnosis and treatment of lens injury, and provided expert recommendations mainly focusing on the application, shortcomings and limitations of current tomographic imaging technology in the diagnosis and treatment of lens injury, and future development directions.

Objective:To investigate the prevalence and risk factors of cornea guttata in patients with age-related cataract.Methods:A cross-sectional study was conducted.A total of 1 472 patients aged 50-89 years with complete medical records, who were diagnosed with age-related cataract and to undergo surgery, were enrolled at Peking University People's Hospital from August 2018 to July 2019.The presence of guttata was determined according to the specular microscopy images and the overall prevalence of guttata was calculated, as well as the prevalence rates of different gender, eye, and age distribution.Patients were divided into a guttata group (96 cases 130 eyes) and a non-guttata group (1 376 cases 2 814 eyes), and the differences in general information between groups were compared.The corneal endothelial cell density (CD), coefficient of variation of cell size (CV), fraction of hexagonal cells (6A), axial length (AL), white to white (WTW), anterior chamber depth, and corneal vertex thickness were compared between the two groups, and only the right eye of the patient with both eyes affected was included for analysis.The risk factors of guttata were analyzed by multivariate logistic regression.Differences in influencing factors among different guttata grades were compared, and the differences in biometric parameters of each eye in both eyes of guttata patients were compared.This study adhered to the Declaration of Helsinki, and the study protocol was approved by the Ethics Committee of Peking University People's Hospital (No.2023PHB198-001).Results:Of the 1 472 patients, 96(6.52%) patients had cornea guttata.The prevalence rate of guttata in males was 4.04%, which was significantly lower than 8.20% in females ( χ2=10.058, P=0.002).The average age of patients in the guttata group was (71.19±8.57) years old, with 24 males and 72 females, including 62 patients with monocular guttata and 39 patients with isolated guttata.Multivariate logistic regression analysis showed that female (odds ratio [ OR]=2.124, 95% confidence interval [ CI]: 1.306-3.455), greater AL ( OR=1.201, 95% CI: 1.083-1.332), shallow anterior chamber depth ( OR=0.439, 95% CI: 0.252-0.766), and greater corneal vertex thickness ( OR=1.008, 95% CI: 1.001-1.015) were risk factors for guttata.There were statistically significant differences in the proportion of monocular guttata and biocular guttata among different grades groups, and between isolated guttata and non-isolated guttata ( χ2=25.492, 15.362; both P<0.05).Differences in CD and corneal vertex thickness among different grades groups were statistically significant ( F=3.264, 5.784; both P<0.05).The CD was significanty higher and the corneal vertex thickness was significantly thinner in the grade 1 than in the grade ≥3 (both P<0.017).There was no statistically significant difference in binocular CD, CV, 6A, AL, WTW, anterior chamber depth, and corneal vertex thickness between both eyes of monocular or binocular guttata patients (all P>0.05). Conclusions:The risk factors of guttata include female, long AL, shallow anterior chamber depth, and thick corneal vertex thickness.The guttata grade of monocular guttata and isolated guttata patients is lower.With the increase of grade, the corneal vertex thickness increases.There is no difference in ocular structure between both eyes of guttata patients.
