Introduction
Intracranial metastases are a common cause of morbidity and mortality in patients with advanced NSCLC, and are frequently managed with radiation therapy (RT). The safety of cranial RT in the setting of treatment with immune checkpoint inhibitors (ICIs) has not been established.Methods
We identified patients with advanced NSCLC with brain metastases who received cranial RT and were treated with or without programmed cell death 1/programmed death ligand 1 inhibitors between August 2013 and September 2016. RT-related adverse events (AEs) were retrospectively evaluated and analyzed according to ICI treatment status, cranial RT type, and timing of RT with respect to ICI.Results
Of 163 patients, 50 (31%) received ICIs, whereas 113 (69%) were ICI naive. Overall, 94 (58%), 28 (17%), and 101 (62%) patients received stereotactic radiosurgery, partial brain irradiation, and/or whole brain RT, respectively. Fifty percent of patients received more than one radiation course. We observed no significant difference in rates of all-grade AEs and grade 3 or higher AEs between the ICI-naive and ICI-treated patients across different cranial RT types (grade ≥3 AEs in 8% of ICI-naive patients versus in 9% of ICI-treated patients for stereotactic radiosurgery [p = 1.00] and in 8% of ICI-naive patients versus in 10% of ICI-treated patients for whole brain RT [p = 0.71]). Additionally, there was no difference in AE rates on the basis of timing of ICI administration with respect to RT.Conclusions
Treatment with an ICI and cranial RT was not associated with a significant increase in RT-related AEs, suggesting that use of programmed cell death 1/programmed death ligand 1 inhibitors in patients receiving cranial RT may have an acceptable safety profile. Nonetheless, additional studies are needed to validate this approach. 相似文献922.

Introduction
Skeletal muscle depletion, referred to as sarcopenia, has recently been identified as a risk factor for poor outcomes in various malignancies. However, the prognostic significance of sarcopenia in patients with NSCLC after surgery has not been adequately determined. This study investigated the impact of sarcopenia in patients undergoing pulmonary resection for lung cancer.Methods
This retrospective study consisted of 328 patients with pathologically confirmed NSCLC who underwent curative resection between January 2005 and April 2017. Preoperative computed tomography imaging at the third lumbar vertebrae level was assessed to measure the psoas muscle mass index (PMI, cm2/m2). Sarcopenia was defined as a cutoff value of PMI less than 6.36 cm2/m2 for males and 3.92 cm2/m2 for females, based on PMI values from “healthy” subjects.Results
The median patient age was 71 years and 59% were male. Sarcopenia was present in 183 (55.8%) and was significantly related with increasing age (p < 0.001), being male (p < 0.001), smoking habit (p < 0.001), lower body mass index (p < 0.001), and postoperative major complication (Clavien-Dindo grade ≥3, p = 0.036). The prevalence of sarcopenia was higher in men than in women, and the prevalence increased with age in men, whereas the prevalence did not increase in females older than 70 years. The 5-year survival rate was 61% in patients with sarcopenia and 91% in those without. Multivariate analysis revealed that sarcopenia was an independent unfavorable prognostic factor (p = 0.019).Conclusions
Sarcopenia as determined using preoperative computed tomography could be used to predict postoperative major complication and prognosis in patients with resected NSCLC. Our results may provide some important information for preoperative management. 相似文献923.

Introduction
The aim of the current study was to investigate whether consolidative local ablative therapy (LAT) can improve the survival of patients with stage IV EGFR-mutant NSCLC who have oligometastatic disease treated with first-line EGFR–tyrosine kinase inhibitor (TKI) therapy.Methods
Patients with stage IV EGFR-mutant NSCLC and no more than five metastases within 2 months of diagnosis were identified. All patients were treated with first-line EGFR-TKIs. Consolidative LAT included radiotherapy, surgery, or both. Overall survival (OS) and progression-free survival (PFS) were estimated by Kaplan-Meier curves.Results
From October 2010 to May 2016, 145 patients were enrolled, including 51 (35.2%) who received consolidative LAT to all oligometastatic sites (all-LAT group), 55 (37.9%) who received consolidative LAT to either primary tumor or oligometastatic sites (part-LAT group), and 39 (26.9%) who did not receive any consolidative LAT (non-LAT group). The median PFS in all-LAT, part-LAT, and non-LAT groups were 20.6, 15.6, and 13.9 months, respectively (p < 0.001). The median OS in all-LAT, part-LAT, and non-LAT groups were 40.9, 34.1, and 30.8 months, respectively (p < 0.001). The difference was statistically significant between the all-LAT group and part-LAT or non-LAT group but was not between the part-LAT and non-LAT group. The median OS was significantly improved with consolidative LAT for primary tumor (40.5 versus 31.5 months, p < 0.001), brain metastases (38.2 versus 29.2 months, p = 0.002), and adrenal metastases (37.1 versus 29.2 months, p = 0.032). Adverse events (grade ≥ 3) due to radiotherapy included pneumonitis (7.7%) and esophagitis (16.9%).Conclusions
The current study showed that consolidative LAT to all metastatic sites was a feasible option for patients with EGFR-mutant oligometastatic NSCLC during first-line EGFR-TKI treatment, with significantly improved PFS and OS compared with consolidative LAT to partial sites or observation alone. 相似文献924.

Introduction
Cancer immunotherapy may alter tumor biology such that treatment effects can extend beyond radiographic progression. In the randomized, phase III OAK study of atezolizumab (anti–programmed death-ligand 1) versus docetaxel in advanced NSCLC, overall survival (OS) benefit with atezolizumab was observed in the overall patient population, without improvement in objective response rate (ORR) or progression-free survival (PFS). We examine the benefit-risk of atezolizumab treatment beyond progression (TBP).Methods
Eight hundred fifty patients included in the OAK primary efficacy analysis were evaluated. Atezolizumab was continued until loss of clinical benefit. Docetaxel was administered until Response Evaluation Criteria in Solid Tumors version 1.1 (RECIST v1.1) disease progression (PD)/unacceptable toxicity; no crossover to atezolizumab was allowed. ORR, PFS, post-PD OS, target lesion change, and safety were evaluated.Results
In atezolizumab-arm patients, ORR was 16% versus 14% and median PFS was 4.2 versus 2.8 months per immune-modified RECIST versus RECIST v1.1. The median post-PD OS was 12.7 months (95% confidence interval [CI]: 9.3–14.9) in 168 atezolizumab-arm patients continuing TBP, 8.8 months (95% CI: 6.0–12.1) in 94 patients switching to nonprotocol therapy, and 2.2 months (95% CI: 1.9–3.4) in 70 patients receiving no further therapy. Of the atezolizumab TBP patients, 7% achieved a post-progression response in target lesions and 49% had stable target lesions. Atezolizumab TBP was not associated with increased safety risks.Conclusions
Within the limitations of this retrospective analysis, the post-PD efficacy and safety data from OAK are consistent with a positive benefit-risk profile of atezolizumab TBP in patients performing well clinically at the time of PD. 相似文献925.

目的研究核苷酸切除修复交叉互补基因1(ERCC1),抑癌基因p53(p53)和B细胞淋巴瘤因子2(bcl-2)基因的表达水平与晚期非小细胞肺癌(NSCLC)患者铂类化疗疗效的关系。方法收集晚期NSCLC患者的肿瘤组织并制备组织芯片,进行ERCC1,p53和bcl-2基因的免疫组织化学染色,检测其在NSCLC组织中的表达情况;同时采集患者外周血检测其血清中ERCC1,p53和bcl-2蛋白的表达情况。根据RECIST肿瘤化疗疗效的评价标准评价患者的疗效,分析影响NSCLC患者铂类化疗疗效的因素及3种基因的表达情况和疗效的关系。结果 ERCC1阴性表达和阳性表达时的化疗有效率分别为55.81%和25.58%(P<0.01);bcl-2阴性表达和阳性表达时的化疗有效率分别为45.28%和25%(P<0.05);p53阴性表达和阳性表达时的化疗有效率分别为53.85%和29.79%(P<0.05)。以ERCC1阴性,同时bcl-2阴性和p53阳性表达的患者人数为最多,与其他各组相比差异有统计学意义(P<0.05),而其他各组人数差异无统计学意义(P>0.05);以ERCC1阴性表达同时bcl-2阳性表达和p53阴性表达的患者采用铂类化疗的有效率为最高,与其他情况相比差异有统计学意义(P<0.05);而ERCC1,bcl-2和p53基因均为阳性表达时的化疗有效率最差,与其他情况相比差异有统计学意义(P<0.01)。结论 ERCC1,p53和bcl-2基因的表达水平可以作为预测NSCLC患者铂类化疗疗效和预后的指标。 相似文献
