文摘Gastric cancer(GC)is the fifth most common malignancy and the fourth leading cause of cancer-related death worldwide,with China bearing nearly half of the global burden[1,2].Most patients are diagnosed at stage Ⅲ–Ⅳ,and despite perioperative therapy plus D2 gastrectomy being the standard of care,long-term survival remains poor[3,4].
文摘BACKGROUND Neutrophil extracellular traps(NETs)are associated with an immunosuppressive tumor microenvironment and may influence the efficacy of immune-based therapies.However,their role in neoadjuvant chemotherapy combined with immunotherapy(NACI)for locally advanced gastric cancer(LAGC)remains unclear.AIM To investigate the prognostic and predictive value of NET density in LAGC patients undergoing NACI.METHODS We enrolled 31 LAGC patients treated with NACI.NET density was assessed through dual immunofluorescence staining of citrullinated histone H3 and myeloperoxidase in pretreatment biopsy and post-treatment surgical specimens.Patients were stratified into high and low pre-NACI NET groups based on median NET density.Pathological complete response(pCR)and overall response rates were evaluated in relation to NET density.Logistic regression analyses were performed to identify independent predictors of treatment outcomes.Dynamic changes in NET density during NACI were also analyzed.RESULTS Patients with low pre-NACI NET density demonstrated significantly higher rates of pCR(40%vs 6%,P=0.037)and overall response(53%vs 12%,P=0.023)compared to those with high NET density.Low pre-NACI NET density and higher programmed death protein ligand 1 expression were identified as independent protective factors for achieving pCR and better response rates.NACI increased NET density;however,this increase was primarily observed in non-pCR and nonresponder groups.Patients in the pCR and responder groups showed stable NET density before and after treatment.Higher post-NACI NET density was associated with poorer respond to NACI.High post-NACI NET density was associated with increased infiltration of immunosuppressive FOXP3+T regulatory cells(P=0.025)and CD68+macrophages(P=0.038).CONCLUSION Pre-NACI NET density serves as a prognostic and predictive biomarker for NACI efficacy in LAGC patients.Low pretreatment NET density is associated with favorable outcomes,while increased post-treatment NET density correlates with poorer response.Targeting NET formation may represent a novel therapeutic strategy to enhance NACI efficacy in LAGC.

文摘BACKGROUND Endoscopy allows for the direct observation of primary tumor characteristics and responses after neoadjuvant treatment.However,reports on endoscopic evaluation following neoadjuvant immunotherapy remain limited.AIM To examine the predictive value of endoscopic findings of primary tumors for responses to neoadjuvant immunotherapy.METHODS This retrospective study,conducted at a tertiary center in China,evaluated 74 patients with colorectal cancer,including 17 with deficient mismatch repair(dMMR)and 15 with proficient mismatch repair(pMMR)tumors.Patients underwent neoadjuvant immunotherapy followed by surgery.Endoscopic findings before and after neoadjuvant immunotherapy were reviewed and compared with the pathology of the resected specimens.RESULTS In the pMMR group(n=57 evaluable patients),endoscopy identified 11/17 patients who achieved a complete response(CR),while misidentifying 1/40 patients with residual disease as CR(64.7%vs 2.5%,P<0.01).Conversely,22/40 patients with residual disease were accurately identified as achieving a partial response(PR),with 1/17 patients who achieved CR misclassified as PR(55.0%vs 5.9%,P<0.01).The sensitivity,specificity,and accuracy of endoscopic diagnosis for pathological CR were 64.7%,97.5%,and 87.7%,respectively.In the dMMR cohort,endoscopy classified 9/17 patients as CR and 2 of the remaining patients with residual tumors as PR(64.3%vs 66.7%,P=0.73).The method demonstrated 100%sensitivity and 82.4%accuracy in diagnosing pathological CR.CONCLUSION Endoscopic evidence of CR or PR was well correlated with postoperative pathological outcomes in the pMMR cohort.Despite endoscopic indications of tumor residue,a complete pathological response post-surgery was possible in the dMMR cohort.

文摘Background:The effect of neoadjuvant immunotherapy on minimally invasive gastrectomy(MIG)for locally advanced gastric cancer(LAGC)remains controversial.This study aimed to compare short-term outcomes between MIG after neoadjuvant chemo-immunotherapy(NICT-MIG)and MIG after neoadjuvant chemotherapy alone(NCT-MIG),and determine risk factors for post-operative complications(POCs).Methods:This retrospective study included clinicopathologic data from 193 patients who underwent NCT-MIG or NICT-MIG between January 2020 and February 2023 in the Department of General Surgery,Chinese People’s Liberation Army General Hospital First Medical Center(Beijing,China).Propensity score-matched analysis at a ratio of 1:2 was performed to reduce bias from confounding patient-related variables and short-term outcomes were compared between the two groups.Results:The baseline characteristics were comparable between 49 patients in the NICT-MIG group and 86 patients in the NCT-MIG group after propensity score matching.Objective and pathologic complete response rates were significantly higher in the NICT-MIG group than in the NCT-MIG group(P<0.05).The overall incidence of treat-related adverse events,intraoperative bleeding,operation time,number of retrieved lymph nodes,time to the first flatus,post-operative duration of hospitalization,overall morbidity,and severe morbidity were comparable between the NCT-MIG and NICT-MIG groups(P>0.05).By multivariate logistic analysis,estimated blood loss of>200mL(P=0.010)and prognostic nutritional index(PNI)score of<45(P=0.003)were independent risk factors for POCs after MIG following neoadjuvant therapy.Conclusions:Safety and feasibility of NICT were comparable to those of NCT in patients undergoing MIG for LAGC.Patients with an estimated blood loss of>200mL or a PNI score of<45 should be carefully evaluated for increased POCs risk.

文摘Immune checkpoint inhibitors(ICIs)have transformed the treatment landscape for resectable non-small cell lung cancer.Numerous trials have explored the use of ICIs,either as monotherapy or in combination with other therapies,in the neoadjuvant setting for stage Ⅰ-Ⅲ non-small cell lung cancer.Most trials have demonstrated neoadjuvant immunotherapy to be safe and to have remarkable efficacy,with a high pathological response rate and significantly improved event-free survival.This review summarizes the findings of Phase Ⅰ-Ⅲ clinical trials investigating various neoadjuvant regimens,including ICI monotherapy,ICI therapy combined with chemother-apy,ICI plus anti-angiogenic therapy,dual ICI therapy,and ICI therapy in combination with radiotherapy or chemoradiotherapy.We discuss the benefits and outcomes associated with each approach.Despite the results being promising,several unresolved issues remain,including identification of reliable biomarkers,the appropri-ate duration of therapy,the optimal treatment regimen for tumors with high programmed cell death ligand 1(PD-L1)expression,the false-negative pathological complete response rate,and the role of digital pathology in assessing the response to treatment.Resistance to immunotherapy,in particular,remains a significant barrier to effective use of ICIs.Given the critical influence of the tumor microenvironment(TME)on the response to treat-ment,we examine the characteristics of the TME in both responsive and resistant tumors as well as the dynamic changes that occur in the TME in response to neoadjuvant immunotherapy.We also summarize the mechanisms underlying T cell responses following neoadjuvant immunotherapy and provide a perspective on strategies to enhance the understanding of tumor heterogeneity,therapy-driven TME remodeling,and overcoming resistance to therapy.Finally,we propose future directions for advancements in personalized neoadjuvant immunotherapy.
文摘Despite existing curative options like surgical removal,tissue destruction techniques,and liver transplantation for early-stage hepatocellular carcinoma(HCC),the rising incidence and mortality rates of this global health burden necessitate continuous exploration of novel therapeutic strategies.This review critically assesses the dynamic treatment panorama for HCC,focusing specifically on the burgeoning role of immunotherapy in two key contexts:early-stage HCC and downstaging advanced HCC to facilitate liver transplant candidacy.It delves into the unique immunobiology of the liver and HCC,highlighting tumor-mediated immune evasion mechanisms.Analyzing the diverse immunothera-peutic approaches including checkpoint inhibitors,cytokine modulators,vaccines,oncolytic viruses,antigen-targeting antibodies,and adoptive cell therapy,this review acknowledges the limitations of current diagnostic markers alpha-fetoprotein and glypican-3 and emphasizes the need for novel biomarkers for patient selection and treatment monitoring.Exploring the rationale for neoadjuvant and adjuvant immunotherapy in early-stage HCC,current research is actively exploring the safety and effectiveness of diverse immunothera-peutic approaches through ongoing clinical trials.The review further explores the potential benefits and challenges of combining immunotherapy and liver transplant,highlighting the need for careful patient selection,meticulous monitoring,and novel strategies to mitigate post-transplant complications.Finally,this review delves into the latest findings from the clinical research landscape and future directions in HCC management,paving the way for optimizing treatment strategies and improving long-term survival rates for patients with this challenging malignancy.

文摘The optimal chemotherapy backbone and specific population of triple-negative breast cancer(TNBC)patients that benefit from neoadjuvant immunotherapy are not well established.This prospective,single-arm,phaseⅡTREND trial assessed the efficacy and safety of tislelizumab plus nab-paclitaxel and epirubicin/cyclophosphamide-based chemotherapy as a neoadjuvant treatment for TNBC(ChiCTR2000035262).The primary endpoint was pathological complete response(pCR),with the secondary endpoints including safety assessment and objective response rate(ORR).ScRNA-seq,bulk RNA-seq,TCR-seq,cyTOF and WES were performed on pre-treatment and post-treatment samples.Among 53 total enrolled patients,44 completed the combined neoadjuvant therapy,and 30 of 44 patients(68.18%)achieved pCR.Additionally,14 out of 44 patients had a complete response(31.82%),with an ORR of 93.18%.The most commonly observed treatment-related adverse events(TRAEs)were alopecia,nausea and liver injury with 6 cases classified as grade 3 or higher adverse events.Immune response-related pathways,including TNF signaling pathway,T cell receptor signaling pathway,were enriched in pCR group.Pre-treatment model was identified and construct to predict response to immunotherapy.CDKN1A+CD8 T lymphocytes were enriched in pCR group after neoadjuvant immunotherapy.Dynamic change of immune-related pathways at an early stage during the neoadjuvant immunotherapy may be associated with the treatment effcacy.In conclusion,neoadjuvant treatment of tislelizumab with nab-paclitaxel and anthracycline-based chemotherapy showed promising clinical activity and was well-tolerated among TNBC patients,without high incidence of TRAEs.These findings provide evidence supporting neoadjuvant tislelizumab with chemotherapy as an effective rational approach for treating TNBC.

文摘Background:Immune checkpoint inhibitors(ICIs)have been included in various neoadjuvant therapy(NAT)regimens for non-small cell lung cancer(NSCLC).However,due to the relatively short period for the use of ICIs in NAT,patients’clinical outcomes with different regimens are uncertain.Our study aims to examine the efficacy of neoadjuvant immunotherapy(NAIT)for NSCLC patients and compare the overall survival(OS)and event-free survival(EFS)of patients receiving different NAT regimens.Methods:This study retrospectively included 308 NSCLC patients treated with different NAT regimens and subsequent surgery in National Cancer Center between August 1,2016 and July 31,2022.Kaplan-Meier survival analysis and Cox proportional hazards regression analysis were conducted to evaluate the prognosis of patients.Results:With a median follow-up of 27.5 months,the 1-year OS rates were 98.8%and 96.2%,and the 2-year OS rates were 96.6%and 85.8%in patients of the NAIT and neoadjuvant chemotherapy(NACT)group,respectively(hazard ratio[HR],0.339;95%confidence interval[CI],0.160-0.720;P=0.003).The 1-year EFS rates were 96.0%and 88.0%,and the 2-year EFS rates were 92.0%and 77.7%for patients in the NAIT and NACT groups,respectively(HR,0.438;95%CI,0.276-0.846;P=0.010).For patients who did not achieve pathological complete response(pCR),significantly longer OS(P=0.012)and EFS(P=0.019)were observed in patients receiving NAIT than those receiving NACT.Different NAT regimens had little effect on surgery and the postoperative length of stay(6[4,7]days vs.6[4,7]days,Z=-0.227,P=0.820).Conclusions:NAIT exhibited superior efficacy to NACT for NSCLC,resulting in longer OS and EFS.The OS and EFS benefits were also observed among patients in the NAIT group who did not achieve pCR.
