BackgroundThe immunohistochemical analysis of programmed cell death ligand 1 (PD-L1) expression in tumor tissue of non–small-cell lung cancer patients has now been integrated in the diagnostic workup. Analysis is commonly done on small tissue biopsy samples representing a minimal fraction of the whole tumor. The aim of the study was to evaluate the correlation of PD-L1 expression on biopsy specimens with corresponding resection specimens.Materials and MethodsIn total, 58 consecutive cases with preoperative biopsy and resected tumor specimens were selected. From each resection specimen 2 tumor cores were compiled into a tissue microarray (TMA). Immunohistochemical staining with the antibody SP263 was performed on biopsy specimens, resection specimens (whole sections), as well as on the TMA.ResultsThe proportion of PD–L1-positive stainings were comparable between the resection specimens (48% and 19%), the biopsies (43% and 17%), and the TMAs (47% and 14%), using cutoffs of 1% and 50%, respectively (P > .39 all comparisons). When the resection specimens were considered as reference, PD-L1 status differed in 16%/5% for biopsies and in 9%/9% for TMAs (1%/50% cutoff). The sensitivity of the biopsy analysis was 79%/82% and the specificity was 90%/98% at the 1%/50% cutoff. The Cohens κ value for the agreement between biopsy and tumor. was 0.70 at the 1% cutoff and 0.83 at the 50% cutoff.ConclusionThe results indicate a moderate concordance between the analysis of biopsy and whole tumor tissue, resulting in misclassification of samples in particular when the lower 1% cutoff was used. Clinicians should be aware of this uncertainty when interpreting PD-L1 reports for treatment decisions.  相似文献

BackgroundImmune checkpoint inhibitors and vascular endothelial growth factor receptor (VEGFR) tyrosine kinase inhibitors are the most commonly used medications in metastatic renal cell carcinoma (mRCC). Recently, large clinical trials have shown favorable outcomes in patients treated with combined immune checkpoint plus VEGFR inhibition compared with VEGFR inhibition alone. However, the benefit among favorable risk (based on International Metastatic Renal Cell Carcinoma Database Consortium score) and elderly (age > 65 years) patients was not clear, leading to a discrepancy between United States Food and Drug Administration and European Association of Urology recommendations.Materials and MethodsWe searched available literature for phase III randomized clinical trials evaluating the efficacy of combining immunotherapy plus VEGF/VEGFR inhibitors versus standard of care in patients with previously untreated mRCC. Combinations that were included in United States Food and Drug Administration recommendations or European Association of Urology guidelines were used for analysis. We performed a meta-analysis with a random effects model to evaluate the efficacy of immunotherapy-VEGFR inhibitor combinations compared with sunitinib in favorable risk and elderly patients.ResultsOur analysis demonstrated that progression-free survival (PFS) was significantly prolonged with combination therapy compared with sunitinib in patients with age > 65 years (hazard ratio, 0.66; 95% confidence interval, 0.52-0.84; P = .001). The PFS in favorable risk disease was improved with combination therapy compared with sunitinib, but the difference was not statistically significant (hazard ratio, 0.68; 95% confidence interval, 0.46-1.01; P = .055).ConclusionOur meta-analysis strengthens the trend of beneficial effect in prolonging PFS in both subgroups compared with each trial alone, indicating that favorable risk and elderly patients with mRCC likely benefit from combining programmed cell death 1 or programmed cell death-ligand 1 and VEGFR inhibition.  相似文献

免疫检查点抑制剂(ICIs)是近年来肿瘤治疗领域的最重要进展之一。随着ICIs适应证的不断拓展及国内原研药相继进入临床,ICIs将用于越来越多的肿瘤患者,然而ICIs的严重不良反应尚未引起临床医师的广泛关注。该文报道1例肝癌术后复发接受帕博利珠单抗治疗引起爆发性心肌炎的病例,患者主要表现为心肌酶升高,难治性心律失常,伴有肝损伤,呼吸衰竭等,虽经积极抢救最终死亡。该例提示ICIs相关免疫性心肌炎早期症状不典型,但疾病呈爆发性进展,需要临床医师早期识别,及早干预。  相似文献

Here, we present an update of a phase 2 study of pembrolizumab in patients with advanced thymic carcinoma who failed previous therapies. Duration of response was approximately 3 years, and median survival was in excess of 2 years with a 5-year survival rate of 18%. The higher than expected incidence of severe autoimmune disorders (15%) did not substantially increase with a longer follow-up. Pembrolizumab induces durable responses in patients with thymic carcinoma. Careful selection of patients and monitoring of toxicities are warranted.  相似文献

The majority of patients with classical Hodgkin lymphoma (cHL) may be cured, but for patients with relapsed or refractory (R/R) cHL, the prognosis is unfavorable. Immune dysfunction is a significant contributor of relapse and a hallmark of cHL; in particular, the immune system is unable to eradicate lymphoma cells that overexpress immune checkpoint proteins. The blocking of this mechanism used by lymphoma cells to evade the immune system has resulted in clinical benefits. Use of checkpoint inhibitors (CPIs) in R/R cHL is associated with high response rates and an acceptable adverse effects profile. There is growing interest in combining chemotherapy with CPIs in frontline therapy of cHL treatment to improve relapse rates without significant additive toxicity. In this review, we discuss the current evidence supporting CPI use in R/R cHL and maintenance therapy. We present emerging CPI data in frontline adult cHL and assess its role in the elderly. In addition, we discuss critical immune-related toxicities and their management, and elaborate on the challenges of monitoring response and minimal residual disease as tools for maximizing efficacy by limiting toxicity.  相似文献

IntroductionThe incidence of kidney cancer is increasing; it could be counteracted with new ways to predict and detect it. We aimed to implement an artificial neural network in order to predict new cases of renal-cell carcinoma (RCC) in the population using population rate, obesity, smoking incidence, uncontrolled hypertension, and life expectancy data in the United States.Patients and MethodsStatistics were collected on US population numbers, life expectancy, obesity, smoking, and hypertension. We used MATLAB R2018 (MathWorks) software to implement an artificial neural network. Data were repeatedly and randomly divided into training (70%) and validation (30%) subsets.ResultsThe number of new RCC cases will grow from 44,400 (2020) to 55,400 (2050), an increase of +24.7%. Our data show that preventing hypertension would have the greatest impact on reduction of the incidence, estimated at ?775 and ?575 cases per year in 2020 and in 2030, respectively. The prevention of obesity and smoking would have a more limited impact, estimated at ?64 and ?180 cases per year in 2020 and in 2030, respectively, for obesity, and ?173 and ?21 cases per year in 2020 and in 2030, respectively, for smoking.ConclusionsOur predictions underline the need for accurate studies on RCC-related risk factors to reduce the incidence.  相似文献

Recent meta-analyses on checkpoint inhibitors in cancer report conflicting data regarding the association of patient gender with inhibitor efficacy. In advanced kidney cancer, checkpoint inhibitors have shown improved outcomes in first- and second-line settings compared with standard of care, but the role of patient gender on treatment outcome is unclear. We aimed to assess the efficacy of immunotherapy according to patient gender in advanced kidney cancer.We performed a systematic review and meta-analysis according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A literature search was performed using PubMed, Scopus, Web of Science, and The Cochrane Library to identify eligible studies published through February 16, 2019. Studies were included if they reported on the differential outcomes of male and female patients with metastatic kidney cancer receiving immunotherapy. Our outcomes of interest were overall survival (OS) or progression-free survival (PFS).Four randomized controlled trials comprising a total of 3664 patients (2715 males and 949 females) met our inclusion criteria. Both men and women with metastatic kidney cancer had an OS and PFS advantage with immunotherapy compared with standard-of-care, but no statistically significant difference between the genders was observed (OS hazard ratio [HR] for men, 0.69; 95% confidence interval [CI], 0.59-0.8; P = .40; HR for women, 0.62; 95% CI, 0.48-0.81; P = .13; PFS HR for men, 0.7; 95% CI, 0.59-0.82; P = .24; HR for women, 0.68; 95% CI, 0.52-0.90; P = .105).In patients with advanced kidney cancer receiving checkpoint inhibitors, there seems to be no association of patient gender with treatment outcome.  相似文献
