Lung cancer is a leading cause of cancer-related morbidity and mortality worldwide. Coupled with the substantial workload, the clinical management of lung cancer is challenged by the critical need to efficiently and accurately process increasingly complex medical information. In recent years, large language models (LLMs) technology has undergone explosive development, demonstrating unique advantages in handling complex medical data by leveraging its powerful natural language processing capabilities, and its application value in the field of lung cancer diagnosis and treatment is continuously increasing. The paper systematically analyzes that the exceptional potential of LLMs in lung cancer auxiliary diagnosis, tumor feature extraction, automatic staging, progression/outcome analysis, treatment recommendations, medical documentation generation, and patient education. However, they face critical technical and ethical challenges including inconsistent performance in complex integrated decision-making (e.g., TNM staging, personalized treatment suggestions) and "black box" opacity issues, along with dilemmas such as training data biases, model hallucinations, data privacy concerns, and cross-lingual adaptation challenges ("data colonization"). Future directions should prioritize constructing high-quality multimodal corpora specific to lung cancer, developing interpretable and compliant specialized models, and achieving seamless integration with existing clinical workflows. Through dual drivers of technological innovation and ethical standardization, LLMs should be prudently advanced for holistic lung cancer management processes, ultimately promoting efficient, standardized, and personalized diagnosis and treatment practices.

Objective:To analyze and compare differences in cortical functioning between patients with post-stroke dysphagia (PSD) following a left hemisphere stroke and healthy individuals using functional near-infrared spectroscopy (fNIRS).Methods:Twenty-six patients recovering from post-stroke dysphagia following a left hemisphere stroke formed the study′s PSD group, and 26 age-matched healthy subjects serves as the HC group. A 41-channel infrared spectroscope was used to record any changes in oxyhemoglobin (HbO) concentration while swallowing and at rest. The fNIRS data were statistically analyzed using Nirspark software. The β-values, reflecting the level of cortical activation, and the swallowing-related specific functional connectivity (FC) strength values (ΔFCs), representing task-specific FC strength, were extracted. The β-values and ΔFCs of the two groups were compared.Results:Compared with the HC group, the PSD group showed significantly reduced activation in Brodmann area (BA) 3/4/6/43 and BA4/6 of the left hemisphere during swallowing. Those areas correspond to the left primary motor cortex (M1), primary somatosensory cortex (S1), premotor cortex, and supplementary motor area (PM). Significantly reduced activation was observed in the PSD group in the right hemisphere at BA45/46/47, BA45/38/48, and BA10, corresponding to the right prefrontal cortex (PFC). The ΔFC values between the left PM-left M1, left PM-left S1, left M1-right S1, and left S1-right M1 in the PSD group were significantly lower than those in the HC group.Conclusions:Left hemispheric PSD is associated not only with decreased activation in the ipsilesional sensorimotor cortex (M1, S1, PM) but also with functional decline in the contra-lesional PFC. During swallowing, persons with left hemispheric PSD exhibit extensive impairment in inter-cortical network connectivity, with particularly marked reductions in connectivity between their ipsilesional and contra-lesional sensorimotor cortices.

Objective To explore the characteritics of spontaneous brain functional activities for patients with hand dysfunction after ischemic stroke using resting state functional magnetic resonance imaging(rs-fMRI).Methods From August,2024 to June,2025,23 patients with hand dysfunction after ischemic stroke were as patients group,and ten age-matched healthy adults were recruited as healthy control group.The patients group was as-sessed with Fugl-Meyer Assessment-Upper Extremities(FMA-UE),Wolf Motor Function Test(WMFT)and modified Lindmark Scale.All subjects underwent rs-fMRI examinations,and the amplitude of low frequency fluctuations(ALFF),fractional amplitude of low frequency fluctuations(fALFF)and regional homogeneity(Re-Ho)were compared between two groups.The resting state functional network was constructed based on indepen-dent component analysis,and the functional connectivity(FC)were analyzed.The rs-fMRI indicators of the pa-tients and the clinical scale scores were analyzed.Results Compared with the healthy control group,the zALFF value decreased in the precentral gyrus(P<0.05,FWE corrected)in the patient group,as well as the values of zfALFF in Cerebelum-Crus2-R(P<0.05,FWE correct-ed),and ReHo values in the putamen(P<0.05,corrected by Alpha Sim).FC of the inferior frontal gyrus(IF-Goperc.R)in the executive control network enhanced(P<0.05,Alpha Sim corrected),while FC of the middle oc-cipital gyrus(MOG.L)in the dorsal attention network(DAN)weakened(P<0.05,Alpha Sim corrected).There was a positive correlation between FC of MOG.L in the patient's DAN and the scores of FMA-UE(r=0.439,P=0.036),WMFT(r=0.516,P=0.012),and modified Lindmark Scales(r=0.425,P=0.043).Conclusion The resting state spontaneous activity of some brain areas of the cerebrum,cerebellum and basal ganglia is reduced in patients with hand dysfunction after ischemic stroke,and some brain network connections are abnor-mal.FC of MOG.L may serve as an objective imaging marker for evaluating hand dysfunction.

Objective:To explore the tumor microenvironment (TME) module associated with pancreatic ductal adenocarcinoma (PDAC) and identify prognostic biomarkers and potential immunotherapeutic targets.Methods:The genetic expression profile data were collected and selected from a dataset of 142 PDAC patients in The Cancer Genome Altas (TCGA) database and 2 microarray datasets (GSE2150, GSE62452) of 168 PDAC patients in Gene Expression Omnibus (GEO) database, and the cell type enrichment analysis of PDAC gene expression data was analyzed by xCell network tool. According to the median cell enrichment score, 142 patients from TCGA were divided into high score group and low score group, and the cell types with prognostic value were determined by univariate survival analysis and validated by GEO datasets. According to the cell type, the differential expression gene analysis and univariate survival analysis were performed to determine the prognosis related differential expression genes (DEGs), and the prognostic DEGs were analyzed by function enrichment analysis and protein-protein interaction (PPI) network analysis. At the same time, GEO dataset was used to verify the prognosis related DEGs of TCGA datasets. Finally, TISIDB database was searched for the common DEGs of TCGA and GEO database, and its correlation with immune system was analyzed.Results:Cell type enrichment analysis showed that Th1 cell and keratinocyte had the same prognostic value in both TCGA and GEO dataset; the overall survival rate of patients with high score was lower than that of those with low score, and the differences were statistically significant (all P values <0.05). 216 prognosis related DEGs were identified, and the results of functional enrichment showed that 9 of the 21 biological process items were closely related to the immune process, and 4 of the 5 KEGG (Kyoto Encyclopedia Of Genes and Genomes) pathways were closely related to the immune process. Through PPI network analysis, CCR7, CD 27, CD 5, CXCL13, ZAP70, MS4A1 and CCL19 were proved to be possibly closely associated with central genes. Through the validation of GEO datasets, there were 15 DEGs with similar prognostic value in GEO and TCGA datasets, which was searched in TISIDB dataset, and the result showed that GIMAP7 was closely related with the immune process of PDAC. Conclusions:A group of 216 TME genes and 7 central genes related to the prognosis of PDAC were identified, and 5 potential targets for immunotherapy of PDAC were provided, including CCR7, CCL19, CD 27, CXCL13 and GIMAP7.
