RESUMEN
Background: Neoadjuvant therapy improves survival benefits in patients with locally advanced non-small cell lung cancer but increases tissue density, presenting challenges for surgeons. Objectives: To compare the differences in surgical complexity and short-term prognostic outcomes between neoadjuvant targeted therapy (NTT) and neoadjuvant chemoimmunotherapy (NCI). Design/methods: This study enrolled 106 patients underwent curative surgery after neoadjuvant therapy between January 2020 and December 2023 at the National Cancer Center of China. Differences in surgical complexity and short-term prognostic outcomes between the two neoadjuvant therapy cohorts were evaluated. The pathological indicators such as pathological response rate and lymph node upstaging/downstaging were then analyzed. Results: In total, 33 patients underwent NTT and 73 underwent NCI preoperatively. Patients who received NTT showed a higher minimally invasive surgery rate (84.8% versus 53.4%, p < 0.01), shorter operative time (144 versus 184 min, p < 0.01), lower conversion rate (3.3% versus 17.8%, p = 0.03), less postoperative drainage (day 3: 140 versus 200 mL, p = 0.03), and lower incidence of postoperative complications including arrhythmias (6.1% versus 26%, p = 0.02). The pathological response rate in the NTT and NCI groups was 70% and 75%, respectively, with the latter group showing a higher complete pathological response rate. The two groups had no significant differences in major pathological response and lymph node pathological response rate. Conclusion: Patients who received NTT presented fewer surgical challenges for surgeons and had better surgical outcomes than those who received NCI therapy, with comparable pathological response rates between the two cohorts. Accordingly, NTT is the preferred induction regimen for patients harboring mutation status.
RESUMEN
INTRODUCTION: Lung cancer (LC) remains a leading cause of cancer mortality worldwide, underscoring the urgent need for novel therapeutic targets. The integration of Mendelian randomization (MR) with proteomic data presents a novel approach to identifying potential targets for LC treatment. METHODS: This study utilized a proteome-wide MR analysis, leveraging publicly available data from genome-wide association studies (GWAS) and protein quantitative trait loci (pQTL) studies. We analyzed genetic association data for LC from the TRICL-ILCCO Consortium and proteomic data from the Decode cohort. The MR framework was employed to estimate the causal effects of specific proteins on LC risk, supplemented by external validation, co-localization analyses, and exploration of protein-protein interaction (PPI) networks. RESULTS: Our analysis identified five proteins (TFPI, ICAM5, SFTPB, COL6A3, EPHB1) with significant associations to LC risk. External validation confirmed the potential therapeutic relevance of ICAM5 and SFTPB. Co-localization analyses and PPI network exploration provided further insights into the biological pathways involved and their potential mechanistic roles in LC pathogenesis. CONCLUSION: The study highlights the power of integrating genomic and proteomic data through MR analysis to uncover novel therapeutic targets for lung cancer. The identified proteins, particularly ICAM5 and SFTPB, offer promising directions for future research and development of targeted therapies, demonstrating the potential to advance personalized medicine in lung cancer treatment.
RESUMEN
BACKGROUND: Several previous studies have examined the association of ambient temperature with drowning. However, no study has investigated the effects of heat-humidity compound events on drowning mortality. METHODS: The drowning mortality data and meteorological data during the five hottest months (May to September) were collected from 46 cities in Southern China (2013-2018 in Guangdong, Hunan and Zhejiang provinces). Distributed lag non-linear model was first conducted to examine the association between heat-humidity compound events and drowning mortality at city level. Then, meta-analysis was employed to pool the city-specific exposure-response associations. Finally, we analysed the additive interaction of heat and humidity on drowning mortality. RESULTS: Compared with wet-non-hot days, dry-hot days had greater effects (excess rate (ER)=32.34%, 95% CI: 24.64 to 40.50) on drowning mortality than wet-hot days (ER=14.38%, 95%CI: 6.80 to 22.50). During dry-hot days, males (ER=42.40%, 95% CI: 31.92 to 53.72), adolescents aged 0-14 years (ER=45.00%, 95% CI: 21.98 to 72.35) and urban city (ER=36.91%, 95% CI: 23.87 to 51.32) showed higher drowning mortality risk than their counterparts. For wet-hot days, males, adolescents and urban city had higher ERs than their counterparts. Attributable fraction (AF) of drowning attributed to dry-hot days was 23.83% (95% CI: 21.67 to 26.99) which was significantly higher than that for wet-hot days (11.32%, 95% CI: 9.64 to 13.48%). We also observed that high temperature and low humidity had an additive interaction on drowning mortality. CONCLUSION: We found that dry-hot days had greater drowning mortality risk and burden than wet-hot days, and high temperature and low humidity might have synergy on drowning mortality.
RESUMEN
PURPOSE: Major pathological response (MPR) has become a surrogate endpoint for overall survival (OS) in non-small cell lung cancer (NSCLC) after neoadjuvant therapy, however, the prognostic histologic features and optimal N descriptor after neoadjuvant therapy are poorly defined. METHODS: We retrospectively analyzed data from 368 NSCLC patients who underwent surgery after neoadjuvant chemotherapy (NAC) from January 2010 to December 2020. The percentage of residual viable tumors in the primary tumor, lymph nodes (LN), and inflammation components within the tumor stroma were comprehensively reviewed. The primary endpoint was OS. RESULTS: Of the 368 enrolled patients, 12.0% (44/368) achieved MPR in the primary tumor, which was associated with significantly better OS (HR, 0.36 0.17-0.77, p = 0.008) and DFS (HR = 0.59, 0.36-0.92, p = 0.038). In patients who did not have an MPR, we identified an immune-activated phenotype in primary tumors, characterized by intense tumor-infiltrating lymphocyte or multinucleated giant cell infiltration, that was associated with similar OS and DFS as patients who had MPR. Neoadjuvant pathologic grade (NPG), consisting of MPR and immune-activated phenotype, identified 30.7% (113/368) patients that derived significant OS (HR 0.28, 0.17-0.46, p < 0.001) and DFS (HR 0.44, 0.31-0.61, p < 0.001) benefit from NAC. Moreover, the combination of NPG and the number of positive LN stations (nS) in the multivariate analysis had a higher C-index (0.711 vs. 0.663, p < 0.001) than the ypTNM Stage when examining OS. CONCLUSION: NPG integrated with nS can provide a simple, practical, and robust approach that may allow for better stratification of patients when evaluating neoadjuvant chemotherapy in clinical practice.

OBJECTIVES: To explore the association between non-high-density lipoprotein (non-HDL) and mortality risk, both short-term and long-term, in Chinese people. DESIGN: A prospective cohort study. SETTING: The National Basic Public Health Service (BPHS) in China. PARTICIPANTS: Including 621 164 elderly individuals around Hunan Province who underwent healthcare management receiving check-ups in China BPHS from 2010 to 2020. EXCLUSION CRITERIA: (1) missing information on gender; (2) missing records of lipid screening; (3) missing information on key covariates; and (4) missing records of comorbidities (cardiovascular disease, hypertension, diabetes, cancer.) PRIMARY AND SECONDARY OUTCOME MEASURES: The study's primary endpoint was all-cause and cause-specific mortality, sourced from Hunan's CDC(Center for Disease Control and Prevention)-operated National Mortality Surveillance System, tracking participants until 24 February 2021. RESULTS: 26 758 (4.3%) deaths were recorded, with a median follow-up of 0.83 years. Association between non-HDL and mortality was non-linear after multivariable adjustment, with the optimum concentration (OC) being 3.29 and 4.85 mmol/L. Compared with OC, the risk increased by 1.12-fold for non-HDL <3.29 mmol/L (HR: 1.12 (1.09 to 1.15)) and 1.08-fold for non-HDL ≥4.85 mmol/L (HR: 1.08 (1.02 to 1.13)) for all-cause mortality. Furthermore, there is also an increased risk of cardiovascular mortality (HR for non-HDL <3.29: 1.10 (1.06 to 1.32) and HR for non-HDL ≥4.85: 1.07 (1.01 to 1.14)). However, cancer mortality risk was significantly increased only for non-HDL <3.29 mmol/L (HR: 1.11 (1.04 to 1.18)). Non-optimum concentration of non-HDL had significant effects on both the long-term and the short-term risk of mortality, especially for risks of mortality for all-cause (log HR:0 .086 (0.038 to 0.134)), cardiovascular (log HR:0 .082 (0.021 to 0.144)), and cancer (log HR:0 .187 (0.058 to 0.315)) within 3 months. A two-sided value of p <0.05 was considered to be statistically significant. CONCLUSIONS: Non-HDL was non-linearly associated with the risk of mortality, and non-optimal concentrations of non-HDL significantly increased short-term mortality in elderly Chinese, which needs more attention for cardiovascular disease prevention.
