BACKGROUND The combination of transarterial chemoembolization(TACE),lenvatinib,and programmed cell death 1(PD-1)inhibitor has been widely used in the treatment of advanced hepatocellular carcinoma(HCC)and has achieved promising results.However,there are few studies comparing whether drug-eluting beads TACE(DTACE)can bring more survival benefits to patients with large HCC compared to conventional TACE(C-TACE)in this triplet therapy.AIM To compare the efficacy and adverse events(AEs)of triple therapy comprising DTACE,PD-1 inhibitors,and lenvatinib(D-TACE-P-L)and C-TACE,PD-1 inhibitors,and lenvatinib(C-TACE-P-L)in patients with large HCC(maximum diameter≥5 cm),and analyze the prognostic factors.METHODS Following a comprehensive review of our hospital’s medical records,this retrospective study included 104 patients:50 received D-TACE-P-L,and 54 received CTACE-P-L.We employed Kaplan-Meier estimation to assess the median progression-free survival(PFS)between the two groups,utilized Cox multivariate regression analysis to identify prognostic factors,and applied theχ2 test to evaluate AEs.RESULTS The objective response rate(ORR)and median PFS were significantly higher in the D-TACE-P-L group compared to the C-TACE-P-L group(ORR:66.0%vs 44.4%,P=0.027;median PFS:6.8 months vs 5.0 months,P=0.041).Cox regression analysis identified treatment option,portal vein tumor thrombus,and hepatic vein invasion as protective factors for PFS.AEs were comparable between the two CONCLUSION D-TACE-P-L may have significantly better PFS and ORR for large HCC,while exhibiting similar AEs to C-TACE-PL. 展开更多

BACKGROUND The combination of programmed cell death protein-1(PD-1)inhibitor and che-motherapy is approved as a standard first-or second-line treatment in patients with advanced oesophageal or gastric cancer.However,it is unclear whether this combination is superior to chemotherapy alone.AIM To assess the comparative effectiveness and tolerability of combining PD-1 inhibitors with chemotherapy vs chemotherapy alone in patients with advanced gastric cancer,gastroesophageal junction(GEJ)cancer,or oesophageal carcinoma.METHODS We searched the PubMed and Embase databases for studies that compared the efficacy and tolerance of PD-1 inhibitors in combination with chemotherapy vs chemotherapy alone in patients with advanced oesophageal or gastric cancer.We employed either random or fixed models to analyze the outcomes of each clinical trial,en-compassing data on overall survival(OS),progression-free survival(PFS),objective response rate,and adverse events(AEs).RESULTS Nine phase 3 clinical trials(7016 advanced oesophageal and gastric cancer patients)met the inclusion criteria.Our meta-analysis demonstrated that the pooled PD-1 inhibitor+chemotherapy group had a significantly longer OS than the chemotherapy-alone group[hazard ratio(HR)=0.76,95%confidence interval(CI):0.71-0.81];the pooled PFS result was consistent with that of OS(HR=0.67,95%CI:0.61-0.74).The count of patients achieving an objective response in the PD-1 inhibitor+chemotherapy group surpassed that of the chemotherapy-alone group[odds ratio(OR)=1.86,95%CI:1.59-2.18].AE incidence was also higher in the combination-therapy group than in the chemotherapy-alone group,regardless of whether≥grade 3 only(OR=1.30,95%CI:1.07-1.57)or all AE grades(OR=1.88,95%CI:1.39-2.54)were examined.We performed a subgroup analysis based on the programmed death-ligand 1(PD-L1)combined positive score(CPS)and noted extended OS and PFS durations within the CPS≥1,CPS≥5,and CPS≥10 subgroups of the PD-1 inhibitor+chemotherapy group.CONCLUSION In contrast to chemotherapy alone,the combination of PD-1 inhibitor and chemotherapy appears to present a more favorable option for initial or subsequent treatment in patients with gastric cancer,GEJ tumor,or oesophageal cancer.This holds true particularly for individuals with PD-L1 CPS scores of≥5 and≥10. 展开更多

Despite the continuous developments and advancements in the treatment of gastric cancer(GC),which is one of the most prevalent types of cancer in China,the overall survival is still poor for most patients with advanced GC.In recent years,with the progress in tumor immunology research,attention has shifted toward immunotherapy as a therapeutic approach for GC.Programmed cell death protein 1(PD-1)inhibitors,as novel immunosuppressive medications,have been widely utilized in the treatment of GC.However,many patients are still resistant to PD-1 inhibitors and experience recurrence in the advanced stages of PD-1 immunotherapy.To reduce the occurrence of drug resistance and recurrence in GC patients receiving PD-1 immunotherapy,to maximize the clinical activity of immunosuppressive drugs,and to elicit a lasting immune response,it is essential to research the tumor microenvironment mechanisms leading to PD-1 inhibitor resistance in GC patients.This article reviews the progress in studying the factors influencing the resistance to PD-1 inhibitors in the GC tumor microenvironment,aiming to provide insights and a basis for reducing resistance to PD-1 inhibitors for GC patients in the future. 展开更多

BACKGROUND Over the years,programmed cell death-1(PD-1)inhibitors have been routinely used for hepatocellular carcinoma(HCC)treatment and yielded improved survival outcomes.Nonetheless,significant heterogeneity surrounds the outcomes of most studies.Therefore,it is critical to search for biomarkers that predict the efficacy of PD-1 inhibitors in patients with HCC.AIM To investigate the role of the C-reactive protein to albumin ratio(CAR)in evaluating the efficacy of PD-1 inhibitors for HCC.METHODS The clinical data of 160 patients with HCC treated with PD-1 inhibitors from January 2018 to November 2022 at the First Affiliated Hospital of Guangxi Medical University were retrospectively analyzed.RESULTS The optimal cut-off value for CAR based on progression-free survival(PFS)was determined to be 1.20 using x-tile software.Cox proportional risk model was used to determine the factors affecting prognosis.Eastern Cooperative Oncology Group performance status[hazard ratio(HR)=1.754,95%confidence interval(95%CI)=1.045-2.944,P=0.033],CAR(HR=2.118,95%CI=1.057-4.243,P=0.034)and tumor number(HR=2.932,95%CI=1.246-6.897,P=0.014)were independent prognostic factors for overall survival.CAR(HR=2.730,95%CI=1.502-4.961,P=0.001),tumor number(HR=1.584,95%CI=1.003-2.500,P=0.048)and neutrophil to lymphocyte ratio(HR=1.120,95%CI=1.022-1.228,P=0.015)were independent prognostic factors for PFS.Two nomograms were constructed based on independent prognostic factors.The C-index index and calibration plots confirmed that the nomogram is a reliable risk prediction tool.The ROC curve and decision curve analysis confirmed that the nomogram has a good predictive effect as well as a net clinical benefit.CONCLUSION Overall,we reveal that the CAR is a potential predictor of short-and long-term prognosis in patients with HCC treated with PD-1 inhibitors.If further verified,CAR-based nomogram may increase the number of markers that predict individualized prognosis. 展开更多

BACKGROUND Programmed death receptor-1(PD-1)inhibitors have been approved as secondline treatment regimen in hepatocellular carcinoma(HCC),but it is still worth studying whether patients can benefit from PD-1 inhibitors as first-line drugs combined with targeted drugs and locoregional therapy.AIM To estimate the clinical outcome of transarterial chemoembolization(TACE)and lenvatinib plus PD-1 inhibitors for patients with unresectable HCC(uHCC).METHODS We carried out retrospective research of 65 patients with uHCC who were treated at Peking Union Medical College Hospital from September 2017 to February 2022.45 patients received the PD-1 inhibitors,lenvatinib,TACE(PD-1-Lenv-T)therapy,and 20 received the lenvatinib,TACE(Lenv-T)therapy.In terms of the dose of lenvatinib,8 mg was given orally for patients weighing less than 60 kg and 12 mg for those weighing more than 60 kg.Of the patients in the PD-1 inhibitor combination group,15 received Toripalimab,14 received Toripalimab,14 received Camrelizumab,4 received Pembrolizumab,9 received Sintilimab,and 2 received Nivolumab,1 with Tislelizumab.According to the investigators’assessment,TACE was performed every 4-6 wk when the patient had good hepatic function(Child-Pugh class A or B)until disease progression occurred.We evaluated the efficacy by the modified Response Evaluation Criteria in Solid Tumors(mRECIST criteria).We accessd the safety by the National Cancer Institute Common Terminology Criteria for Adverse Events,v 5.0.The key adverse events(AEs)after the initiation of combination therapy were observed.RESULTS Patients with uHCC who received PD-1-Lenv-T therapy(n=45)had a clearly longer overall survival than those who underwent Lenv-T therapy(n=20,26.8 vs 14.0 mo;P=0.027).The median progression-free survival time between the two treatment regimens was also measured{11.7 mo[95%confidence interval(CI):7.7-15.7]in the PD-1-Lenv-T group vs 8.5 mo(95%CI:3.0-13.9)in the Lenv-T group(P=0.028)}.The objective response rates of the PD-1-Lenv-T group and Lenv-T group were 44.4%and 20%(P=0.059)according to the mRECIST criteria,meanwhile the disease control rates were 93.3%and 64.0%(P=0.003),respectively.The type and frequency of AEs showed little distinction between patients received the two treatment regimens.CONCLUSION Our results suggest that the early combination of PD-1 inhibitors has manageable toxicity and hopeful efficacy in patients with uHCC. 展开更多

BACKGROUND Bevacizumab,an anti-vascular endothelial growth factor(VEGF)monoclonal antibody,inhibits angiogenesis and reduces tumor growth.Serum VEGF-C,lactate dehydrogenase,and inflammatory markers have been reported as predictive markers related to bevacizumab treatment.Programmed cell death ligand 1(PD-L1)could act upon VEGF receptor 2 to induce cancer cell angiogenesis and metastasis.AIM To investigate the efficacy of bevacizumab-containing chemotherapy in patients with metastatic colorectal cancer(CRC)according to the expression of PD-L1.METHODS This analysis included CRC patients who received bevacizumab plus FOLFOX or FOLFIRI as first-line therapy between June 24,2014 and February 28,2022,at Samsung Medical Center(Seoul,South Korea).Analysis of patient data included evaluation of PD-L1 expression by the combined positive score(CPS).We analyzed the efficacy of bevacizumab according to PD-L1 expression status in patients with CRC.RESULTS A total of 124 patients was included in this analysis.Almost all patients were treated with bevacizumab plus FOLFIRI or FOLFOX as the first-line chemotherapy.While 77%of patients received FOLFOX,23%received FOLFIRI as backbone first-line chemotherapy.The numbers of patients with a PD-L1 CPS of 1 or more,5 or more,or 10 or more were 105(85%),64(52%),and 32(26%),respectively.The results showed no significant difference in progression-free survival(PFS)and overall survival(OS)with bevacizumab treatment between patients with PDL1 CPS less than 1 and those with PD-L1 CPS of 1 or more(PD-L1<1%vs PD-L1≥1%;PFS:P=0.93,OS:P=0.33),between patients with PD-L1 CPS less than 5 and of 5 or more(PD-L1<5%vs PD-L1≥5%;PFS:P=0.409,OS:P=0.746),and between patients with PD-L1 CPS less than 10 and of 10 or more(PD-L1<10%vs PD-L1≥10%;PFS:P=0.529,OS:P=0.568).CONCLUSION Chemotherapy containing bevacizumab can be considered as first-line therapy in metastatic CRC irrespective of PD-L1 expression. 展开更多

In this editorial,we comment on the article(World J Gastrointest Oncol 2024;16:1236-1247),which is a retrospective study of transarterial chemoembolization(TACE)combined with multi-targeted tyrosine kinase inhibitor(TKI)and programmed cell death protein-1(PD-1)inhibitor for the treatment of unresectable hepatocellular carcinoma(HCC).Herein,we focus specifically on the mechanisms of this triple therapy,administration sequence and selection of each medication,and implications for future clinical trials.Based on the interaction mechanisms between medications,the triple therapy of TACE+TKI+PD-1 is proposed to complement the deficiency of each monotherapy,and achieve synergistic antitumor effects.Although this triple therapy has been evaluated by several retrospective trials,it is still controversial whether the triple therapy achieves better clinical benefits,due to the flawed study design and heterogeneity in medications.In addition,the administration sequence,which may greatly affect the clinical benefit,needs to be fully considered at clinical decision-making for obtaining better prognosis.We hope that this editorial could contribute to the design and optimization of future trials. 展开更多

BACKGROUND Diffuse large B-cell lymphoma(DLBCL)is a common aggressive non-Hodgkin's lymphoma(NHL),accounting for 30%-40%of adult NHL.Primary testicular(PT)lymphoma is an uncommon extranodal disease representing approximately 1%-2%of lymphoma.Approximately 30%–40%of patients are refractory to frontline therapy or relapse after complete remission.Refractory DLBCL responds poorly to other lines of chemotherapy,and experiences short-term survival.CASE SUMMARY We present a 41-year-old male patient who was diagnosed with PT-DLBCL.Further disease progression was observed after multiline chemotherapy.Chimeric antigen receptor T cells(CAR-T)therapy salvaged the patient.Unfortunately,a new mass was observed in the right adrenal area after six months.The patient was administered programmed cell death protein-1(PD-1)inhibitor therapy and maintained progression-free survival at more than 17 mo of follow-up.CONCLUSION Our findings support the potential benefit of CAR-T combined with PD-1 inhibitor therapies in this type of relapsed and refractory PT-DLBCL. 展开更多

BACKGROUND Chimeric antigen receptor T cell(CART)therapy has benefited many refractory lymphoma patients,but some patients experience poor effects.Previous studies have shown that programmed cell death protein-1(PD-1)inhibitors can improve and prolong the therapeutic effect of CAR-T cell treatment.CASE SUMMARY A 61-year-old male presented with 15-d history of diarrhea and lower-limb edema.A large mass was detected in the pelvis,and pathology indicated non-Hodgkin diffuse large B-cell lymphoma.After three cycles of the R-CHOP chemotherapeutic regimen,the patient showed three subcutaneous nodules under the left armpit and both sides of the cervical spine.Pathological examination of the nodules indicated DLBCL again.The patient was diagnosed with relapsed and refractory diffuse large B-cell lymphoma.We recommended CAR-T cell treatment.Before treatment,the patient’s T cell function and expression of immune detection points were tested.Expression of PD-1 was obviously increased(52.7%)on cluster of differentiation(CD)3+T cells.The PD-1 inhibitor(3 mg/kg)was infused prior to lymphodepleting chemotherapy with fludarabine and cyclophosphamide.CAR-CD19 T cells of 3×10^(6)/kg and CAR-CD22 T cells 1×10^(6)/kg were infused,respectively.The therapeutic effect was significant,and the deoxyribonucleic acid copy numbers of CAR-CD19 T cells and CAR-CD22 T cells were stable.Presently,the patient has been disease-free for more than 12 mo.CONCLUSION This case suggests that the combination of PD-1 inhibitors and CAR-T cellsimproved therapeutic efficacy in B-cell lymphoma. 展开更多

Lymphoma,which is highly malignant,stems from lymph nodes and lymphoid tissue.Lymphoma cells express programmed death-ligand 1/2(PD-L1/PD-L2),which binds with programmed cell death 1 protein(PD-1)to establish inhibitory signaling that impedes the normal function of T cells and allows tumor cells to escape immune system surveillance.Recently,immune checkpoint inhibitor immunotherapies such as PD-1 inhibitors(nivolumab and pembrolizumab)have been introduced into the lymphoma treatment algorithm and have shown remarkable clinical efficacy and greatly improve prognosis in lymphoma patients.Accordingly,the number of lymphoma patients who are seeking treatment with PD-1 inhibitors is growing annually,which results in an increasing number of patients developing immune-related adverse events(irAEs).The occurrence of irAEs inevitably affects the benefits provided by immunotherapy,particularly when PD-1 inhibitors are applied.However,the mechanisms and characteristics of irAEs induced by PD-1 inhibitors in lymphoma need further investigation.This review article summarizes the latest research advances in irAEs during treatment of lymphoma with PD-1 inhibitors.A comprehensive understanding of irAEs incurred in immunotherapy can help to achieve better efficacy with PD-1 inhibitors in lymphoma. 展开更多

The recent discovery of immune checkpoints inhibitors, especially anti-programmed cell death protein 1(PD-1)and anti-programmed cell death protein ligand 1(PD-L1) monoclonal antibodies, has opened new scenarios in the management of non-small cell lung cancer(NSCLC) and this new class of drugs has achieved a rapid development in the treatment of this disease. However, considering the costs of these drugs and the fact that only a subset of patients experience long-term disease control, the identification of predictive biomarkers for the selection of candidates suitable for treatment has become a priority. The research focused mainly on the expression of the PD-L1 receptor on both tumor cells and/or immune infiltrates determined by immunohistochemistry(IHC). However, different checkpoint inhibitors were tested, different IHC assays were used, different targets were considered(tumor cells, immune infiltrates or both) and different expression thresholds were employed in clinical trials. In some trials the assay was used prospectively to select the patients, while in other trials it was evaluated retrospectively. Some confusion emerges, which makes it difficult to easily compare the literature data and to translate them in practice management. This mini-review shows the possibilities and pitfalls of the PD-L1 expression to predict the activity and efficacy of anti PD1/PD-L1 monoclonal antibodies in the treatment of NSCLC. 展开更多

BACKGROUND Programmed cell death-1(PD-1)inhibitor has been indicated for many types of malignancies.However,these inhibitors also cause immune-related adverse events.Hepatobiliary disorder is a phenotype of immune-related adverse event affecting 0%–4.5%of patients treated with PD-1 inhibitors.Recent studies have reported PD-1 inhibitor-related sclerosing cholangitis(SC);however,the associated clinical and pathological features are unclear.AIM To evaluate the clinical and pathological features of PD-1 inhibitor-related SC through a systematic review of the literature.METHODS The review,conducted using electronic databases in PubMed,was restricted to the period from January 2014 to September 2019 and focused on case reports/series on PD-1 inhibitor-related SC published in English.We scanned the references of the selected literature to identify any further relevant studies.Six cases previously studied by us,including three that have not yet been published,were included in this review.RESULTS Thirty-one PD-1 inhibitor-related SC cases were evaluated.Median age of patients was 67 years(range,43–89),with a male to female ratio of 21:10.The main disease requiring PD-1 inhibitor treatment was non-small cell lung cancer.Agents that caused PD-1 inhibitor-related SC were nivolumab(19 cases),pembrolizumab(10 cases),avelumab(1 case),and durvalumab(1 case).The median number of cycles until PD-1 inhibitor-related SC onset was 5.5(range,1–27).Abdominal pain or discomfort(35.5%,11/31)was the most frequent symptom.Blood serum tests identified liver dysfunction with a notable increase in biliary tract enzymes relative to hepatic enzymes,and a normal level of serum immunoglobulin G4.Biliary dilation without obstruction(76.9%,20/26),diffuse hypertrophy of the extrahepatic biliary tract(90.5%,19/21),and multiple strictures of the intrahepatic biliary tract(30.4%,7/23)were noted.In 11/23(47.8%)cases,pathological examination indicated that CD8+T cells were the dominant inflammatory cells in the bile duct or peribiliary tract.Although corticosteroids were mainly used for PD inhibitor-related SC treatment,the response rate was 11.5%(3/26).CONCLUSION Some clinical and pathological features of PD-1 inhibitor-related SC were revealed.To establish diagnostic criteria for PD-1 inhibitor-related SC,more cases need to be evaluated. 展开更多

BACKGROUND Hepatic arterial infusion chemotherapy(HAIC)has been proven to be an ideal choice for treating unresectable hepatocellular carcinoma(uHCC).HAIC-based treatment showed great potential for treating uHCC.However,large-scale studies on HAIC-based treatments and meta-analyses of first-line treatments for uHCC are lacking.AIM To investigate better first-line treatment options for uHCC and to assess the safety and efficacy of HAIC combined with angiogenesis inhibitors,programmed cell death of protein 1(PD-1)and its ligand(PD-L1)blockers(triple therapy)under real-world conditions.METHODS Several electronic databases were searched to identify eligible randomized controlled trials for this meta-analysis.Study-level pooled analyses of hazard ratios(HRs)and odds ratios(ORs)were performed.This was a retrospective single-center study involving 442 patients with uHCC who received triple therapy or angiogenesis inhibitors plus PD-1/PD-L1 blockades(AIPB)at Sun Yat-sen University Cancer Center from January 2018 to April 2023.Propensity score matching(PSM)was performed to balance the bias between the groups.The Kaplan-Meier method and cox regression were used to analyse the survival data,and the log-rank test was used to compare the suvival time between the groups.RESULTS A total of 13 randomized controlled trials were included.HAIC alone and in combination with sorafenib were found to be effective treatments(P values for ORs:HAIC,0.95;for HRs:HAIC+sorafenib,0.04).After PSM,176 HCC patients were included in the analysis.The triple therapy group(n=88)had a longer median overall survival than the AIPB group(n=88)(31.6 months vs 14.6 months,P<0.001)and a greater incidence of adverse events(94.3%vs 75.4%,P<0.001).CONCLUSION This meta-analysis suggests that HAIC-based treatments are likely to be the best choice for uHCC.Our findings confirm that triple therapy is more effective for uHCC patients than AIPB. 展开更多

BACKGROUND The effectiveness of regorafenib plus programmed cell death-1(PD-1)inhibitor in treating microsatellite stable(MSS)metastatic colorectal cancer(mCRC)remains controversial.AIM To investigate the benefits of regorafenib combined with PD-1 inhibitor in treating MSS mCRC and explore indicators predicting response.METHODS This retrospective study included a total of 30 patients with microsatellite stable metastatic colorectal cancer treated with regorafenib combined with programmed cell death-1 inhibitor at Henan Provincial People’s Hospital between December 2018 and December 2020.During a 4-wk treatment cycle,regorafenib was performed for 3 continuous weeks.PD-1 inhibitor was intravenously injected starting on the first day of the oral intake of regorafenib.We reviewed tumor response,progression-free survival(PFS),overall survival,and treatment-related adverse events(TRAEs)and evaluated association between platelet-tolymphocyte ratio(PLR)and outcomes in this retrospective study.RESULTS Stable disease and progressive disease were found in 18(60.0%)and 12(40.0%)patients,respectively.The disease control rate was 60.0%.The median follow-up time was 12.0 mo,and median PFS was 3.4 mo[95%confidence interval(CI):2.2-4.6 mo].Of the 12 patients with progressive disease,10(83.3%)had liver metastasis before starting the combined treatment.Among the 18 patients with SD,10(55.6%)did not have liver metastases.One patient without liver metastases at baseline was found with a substantially prolonged PFS of 11.2 mo.The liver metastasis,the choice of programmed cell death-1 inhibitor other than nivolumab or pembrolizumab and previous exposure to regorafenib was’t associated with treatment outcome.The median PFS in the low-PLR group was 4.2 mo(95%CI:3.5-4.9 mo),compared with 2.8 mo(95%CI:1.4-4.2 mo)in the high-PLR group(P=0.005).The major TRAEs included hand-foot syndrome(33.3%),hypertension(23.3%),malaise(20.0%),and gastrointestinal reaction(16.7%).The incidence of grade 3 TRAEs was 13.3%(4/30),which comprised abnormal capillary proliferation(n=1),transaminase elevation(n=1),and hand-foot syndrome(n=2).No grade 4 or higher toxicity was observed.CONCLUSION Regorafenib combined with PD-1 inhibitor could lead to a longer PFS in some patients with MSS mCRC.The PLR might be a prediction of the patient response to this therapy. 展开更多

Objective: IMpower210(NCT02813785) explored the efficacy and safety of single-agent atezolizumab vs.docetaxel as second-line treatment for advanced non-small cell lung cancer(NSCLC) in East Asian patients.Methods: Key eligibility criteria for this phase Ⅲ, open-label, randomized study included age ≥18 years;histologically documented advanced NSCLC per the Union for International Cancer Control/American Joint Committee on Cancer staging system(7th edition);Eastern Cooperative Oncology Group performance status of 0 or 1;and disease progression following platinum-based chemotherapy for advanced or metastatic NSCLC. Patients were randomized 2:1 to receive either atezolizumab(1,200 mg) or docetaxel(75 mg/m^(2)). The primary study endpoint was overall survival(OS) in the intention-to-treat(ITT) population with wild-type epidermal growth factor receptor expression(ITT EGFR-WT) and in the overall ITT population.Results: Median OS in the ITT EGFR-WT population(n=467) was 12.3 [95% confidence interval(95% CI),10.3-13.8] months in the atezolizumab arm(n=312) and 9.9(95% CI, 7.8-13.9) months in the docetaxel arm[n=155;stratified hazard ratio(HR), 0.82;95% CI, 0.66-1.03]. Median OS in the overall ITT population was 12.5(95% CI, 10.8-13.8) months with atezolizumab treatment and 11.1(95% CI, 8.4-14.2) months(n=377) with docetaxel treatment(n=188;stratified HR, 0.87;95% CI, 0.71-1.08). Grade 3/4 treatment-related adverse events(TRAEs) occurred in 18.4% of patients in the atezolizumab arm and 50.0% of patients in the docetaxel arm.Conclusions: IMpower210 did not meet its primary efficacy endpoint of OS in the ITT EGFR-WT or overall ITT populations. Atezolizumab was comparatively more tolerable than docetaxel, with a lower incidence of grade3/4 TRAEs. 展开更多
