The 2025 American Society of Clinical Oncology Gastrointestinal Cancers Symposium (ASCO-GI) was held from January 23 to 25, 2025. Several significant studies on the treatment of esophageal and gastroesophageal junction (GEJ) cancer were presented at the symposium, highlighting notable advances, particularly in the perioperative and advanced settings. Immunotherapy has demonstrated significant promise in the neoadjuvant treatment of esophageal cancer, showing potential to become a standard treatment. Furthermore, the long-term survival benefits of combining immunotherapy with chemotherapy for advanced GEJ cancer were further validated. This article summarizes and interprets the researches presented at the symposium concerning perioperative and advanced treatments for esophageal and GEJ cancers.

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.

Under the background of climate change, the escalating air pollution and extreme weather events have been identified as risk factors for chronic respiratory diseases (CRD), causing serious public health burden worldwide. This review aims to summarize the effects of changed atmospheric environment caused by climate change on CRD. Results indicated an increased risk of CRD (mainly COPD, asthma) associated with environmental factors, such as air pollutants, adverse meteorological conditions, extreme temperatures, sandstorms, wildfire, and atmospheric allergens. Furthermore, this association can be modified by factors such as socioeconomic status, adaptability, individual behavior, medical services. Potential pathophysiological mechanisms linking climate change and increased risk of CRD involved pulmonary inflammation, immune disorders, oxidative stress. Notably, the elderly, children, impoverished groups and people in regions with limited adaptability are more sensitive to respiratory health risks caused by climate change. This review provides a reference for understanding risk factors of CRD in the context of climate change, and calls for the necessity of adaptive strategies. Further interdisciplinary research and global collaboration are needed in the future to enhance adaptability and address climate health inequality.

The cooccurrence of NPM1, FLT3-ITD, and DNMT3A mutations (i.e., triple mutation) is related to dismal prognosis in patients with acute myeloid leukemia (AML) receiving chemotherapy alone. In this multicenter retrospective cohort study, we aimed to identify whether allogeneic hematopoietic stem cell transplantation (allo-HSCT) could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut AML across four transplant centers in China. Fifty-three patients with triple-mutated AML receiving allo-HSCT in complete remission were enrolled. The 1.5-year probabilities of relapse, leukemia-free survival, and overall survival after allo-HSCT were 11.9%, 80.3%, and 81.8%, respectively. Multivariate analysis revealed that more than one course of induction chemotherapy and allo-HSCT beyond CR1 were associated with poor survival. To our knowledge, this work is the largest study to explore the up-to-date undefined role of allo-HSCT in patients with triple-mutated AML. Our real-world data suggest that allo-HSCT could overcome the poor prognosis of DNMT3A^mutNPM1^mutFLT3-ITD^mut in AML.

Advanced gastric cancer(AGC)includes locally unresectable gastric cancer(GC),metastatic GC,and postoperative recurrent GC.Due to delayed diagnosis and lack of effective treatment for AGC,the median survival time of AGC patients is only 6-12 months.At present,the main treatment goal of AGC is to improve symptoms and prolong the survival time of patients receiving sequential chemotherapy.Although the therapeutic effect of systemic therapy on AGC is gradually becoming apparent,the patient's prognosis is far from expected.In addition,targeted therapy and novel immunotherapy have drawbacks such as high incidence of drug resistance,high toxic side effects,and heavy economic burden on patients.Therefore,finding new therapeutic targets and developing anti-tumor drugs is a key issue that urgently needs to be addressed.According to reports,abnormal activation of the hepatocyte growth factor(HGF)/cellular-mesenchymal epithelial transition factor(c-MET)pathway plays a crucial role in the progression of GC and the occurrence of multi-line resistance and may be a potential therapeutic target for GC.In recent years,some HGF/c-MET-targeting small molecule tyrosine kinase inhibitors(TKIs)have been found to show good clinical effects in the treatment of GC.Meanwhile,new HGF/c-MET inhibitors(such as monoclonal antibodies,bispecific antibodies,antibody drug conjugates,etc.)have shown good anti-tumor activity in preclinical studies,but they are all at different stages of clinical research,and their efficacy and safety still need further confirmation.This review elaborates on the latest research progress of HGF/c-MET inhibitors in the treatment of AGC and discusses the main reasons and strategies for drug resistance,aiming to provide better guidance for the treatment of AGC and provide reference for future research.

Objective:To investigate the application value of a multi-dimensional digital moni-toring platform for perioperative period in gastric cancer patients.Methods:The retrospective cohort study was conducted.

The blood oxygen was changed from 97.00%(5.00%) to 97.50%(3.00%), showing no significant difference before and after operation ( F=2.25, P>0.05). (3) Results of exercise and sleep monitoring. From preoperation to the third day after surgery, the number of steps fo 50 pati-ents was changed from 3 043(1 224) to 1 473(767), sleep duration was changed from(8.2±1.1)hours to(7.3±0.8)hours, sleep score was changed from 80±10 to 78±5,showing significant differences in above indicators before and after operation ( F=716.46, 29.02, 47.32, P<0.05).(4) Results of body composition monitoring. The body weight of 50 patients was changed from (63±8)kg to(61±8)kg before and after operation, body fat rate was changed from 24%±8% to 22%±9%, muscle mass was changed from 43 (12)kg to 41(17)kg, body mass index was changed from (23.0±2.6)kg/m 2 to(22.1±2.5)kg/m 2, showing significant differences in above indicators before and after operation ( t=8.19, 3.00, Z=-2.78, t=7.34, P<0.05), while there was no significant difference in basal metabolic indicators from (1 390±134)kcal to (1 379±139)kcal before and after operation ( t=1.02, P>0.05). Conclusion:The multi-dimensional digital monitoring platform for preoperative period can accurately monitor the perioperative stress level and evaluate the postoperative recovery of gastric cancer patients, which can present the visual results.

Objective:To construct an assessment tool for laparoscopic left lateral sectionectomy skills.Methods:From November 2023 to January 2024, 22 clinical experts in hepatopancreatobiliary surgery from different regions of China were selected for this study. A preliminary indicator system was established through literature review, and the indicators and their weights at each level were determined using the Delphi method and analytic hierarchy process (AHP).Results:In the two rounds of consultation, the expert positive coefficients were 100.00% and 90.91%, authority coefficients were 0.984 and 0.985, Kendall coefficients were 0.231 and 0.193 ( P<0.001), and Cronbach's α coefficients were 0.905 and 0.865, respectively. A skill assessment tool for laparoscopic left lateral sectionectomy skills was constructed consisting of 5 primary indicators and 23 secondary indicators. AHP analysis showed that the concordance rate of each matrix of the secondary indicators was <0.1, meeting the consistency test requirements. Conclusions:The assessment tool for laparoscopic left lateral sectionectomy skills developed in this study is objective and reliable for evaluating the surgical skills of novice surgeons.
