| 1 | 帕博利珠单抗单用或与放疗联用治疗转移性非小细胞肺癌:两个随机试验的汇总分析显示文摘背景放疗可以提高整个机体对免疫治疗的应答。在Ⅱ期PEMBRO-RT研究和Ⅰ/Ⅱ期MDACC研究中,患有转移性非小细胞肺癌(NSCLC)的患者被随机分配入组,接受免疫治疗(帕博利珠单抗)+放疗联合疗法,或免疫治疗单一疗法。当上述2个研究单独分析时,联合疗法组显示出潜在获益。由于每个研究的样本量较小,缓解率和结局并未显示出统计学意义,然而却有显著的临床获益。因此,本研究进行汇总分析,来判断放疗是否会改善转移性NSCLC患者的免疫治疗应答。方法PEMBRO-RT和MDACC研究纳入标准:患者年龄≥18岁,患有转移性NSCLC,且有≥1处未经放疗照射的病灶,以便进行射野外应答监测。PEMBRO-RT研究纳入曾接受过化疗患者,MDACC研究纳入曾接受过治疗或新诊断患者。2个研究中的患者均未接受过免疫治疗。在PEMBRO-RT研究中患者被等比例随机分配入组,并根据吸烟状态进行分层(分为<10年组和≥10年组)。MDACC研究的患者根据放疗计划可行性被等比例随机分配入2个受试组。由于联合治疗组的干预本质,每个研究中的放疗均不适用盲法。在2个研究中,不论是否进行放疗,均静脉滴入帕博利珠单抗(每3周200 mg)。在PEMBRO-RT研究中,在放疗(24 Gy 3次分割照射)结束后1周给予第1剂帕博利珠单抗。在MDACC研究中,在第1次放疗(50 Gy 4次分割照射或45 Gy 15次分割照射)同时给予帕博利珠单抗。仅检测未经照射病灶的应答。本研究的终点为最佳射野外(远隔)应答率(ARR)、最佳射野外疾病控制率(ACR)、12周时ARR、12周时ACR、无进展生存期(PFS)和总生存期(OS)。2个研究的意向治疗(ITT)人群均纳入分析。PEMBRO-RT研究(NCT02492568)和MDACC研究(NCT02444741)均在ClinicalTrials.gov上注册。发现纳入148例患者,76例接受帕博利珠单抗治疗,72例接受帕博利珠单抗+放疗治疗。所有患者随访时间中位数为33个月[四分位距(IQR):32.4~33.6]。148例患者中124例(84%)组织学特征为非鳞癌,111例(75%)患者曾经接受过化疗。组间没有基线特征差异,包括PD-L1表达状态和转移灶体积。最常见的照射部位为肺转移灶(39%,28/72)、胸腔内淋巴结(21%,15/72)和非原发灶(17%,12/72)。帕博利珠单抗组和联合治疗组的最佳ARR分别为19.7%(15/76)和41.7%(30/72),OR=2.96,95%CI:1.42~6.20,P=0.0039;最佳ACR分别为43.4%(33/76)和65.3%(47/72),OR=2.51,95%CI:1.28~4.91,P=0.0071;PFS中位数分别为4.4(IQR:2.9~5.9)和9.0个月(IQR:6.8~11.2),HR=0.67,95%CI:0.45~0.99,P=0.045;OS中位数分别为8.7(IQR:6.4~11.0)和19.2个月(IQR:14.6~23.8),OR=0.67,95%CI:0.54~0.84,P=0.0004。在汇总分析中没有发现新的安全问题。解读帕博利珠单抗免疫疗法+放疗显著提高转移性NSCLC患者的应答和改善治疗结局。这些结果需要在三期临床试验中进行验证。 | 陈大卫(翻译) 于金明(校对) Willemijn S M E Theelen Vivek Verma Brian P Hobbs Heike M U Peulen Joachim G J V Aerts Idris Bahce Anna Larissa N Niemeijer Joe Y Chang Patricia M de Groot Quynh-Nhu Nguyen Nathan I Comeaux George R Simon Ferdinandos Skoulidis Steven H Lin Kewen He Roshal Patel John Heymach Paul Baas James W Welsh | 2021 | 中华肿瘤防治杂志2021，28，24： | 49 |

| 3 | 在诊断 choledochal 包囊的磁性的回声 cholangiopancreatography 的角色: 盒子系列和评论显示文摘 AIM:To determine the merits of magnetic resonance cholangiopancreatography(MRCP) as the primary diagnostic test for choledochal cysts(CC’s).METHODS:Between 2009 and 2012,patients who underwent MRCP for perioperative diagnosis were identified.Demographic information,clinical characteristics,and radiographic findings were recorded.MRCP results were compared with intraoperative findings.A PubMed search identified studies published between 1996-2012,employing MRCP as the primary preoperative imaging and comparing results with either endoscopic retrograde cholangiopancreatography(ERCP) or operative findings.Detection rates for CC’s and abnormal pancreaticobiliary junction(APBJ) were calculated.In addition detection rates for clinically related biliary pathology like choledocholithiasis and cholangiocarcinomas in patients diagnosed with CC’s were also evaluated.RESULTS:Eight patients were identified with CC’s.Six patients out of them had typeⅣCC’s,1 had type I and 1 had a new variant of choledochal cyst with confluent dilatation of the common bile duct(CBD) and cystic duct.Seven patients had an APBJ and 3 of those had a long common-channel.Gallstones were found in 2 patients,1 had a CBD stone,and 1 pancreatic-duct stone was also detected.In all cases,MRCP successfully identified the type of CC’s,as well as APBJ with ductal stones.From analyzing the literature,we found that MRCP has 96%-100% detection rate for CC’s.Additionally,we found that the range for sensitivity,specificity,and diagnostic accuracy was 53%-100%,90%-100% and 56%-100% in diagnosing APBJ.MRCP’s detection rate was 100% for choledocholithiasis and 87% for cholangiocarcinomas with concurrent CC’s.CONCLUSION:After initial ultrasound and computed tomography scan,MRCP should be the next diagnostic test in both adult and pediatric patients.ERCP should be reserved for patients where therapeutic intervention is needed. | Vikas Y Sacher James S Davis Danny Sleeman Javier Casillas | 2013 | World Journal of Radiology2013，5，8： | 15 |
| 4 | miR-182参与调节胶质母细胞瘤的凋亡、生长和分化(英文)显示文摘Glioblastoma multiforme(GBM)is a lethal,therapy-resistant brain cancer consisting of numerous tumor cell subpopulations,including stem-like glioma-initiating cells(GICs),which contribute to tumor recurrence following initial response to therapy.Here,we identified miR-182 as a regulator of apoptosis,growth,and differentiation programs whose expression level is correlated with GBM patient survival.Repression of Bcl2-like12(Bcl2L12),c-Met,and hypoxia-inducible factor 2α(HIF2A)is of central importance to miR-182 anti-tumor activity,as it results in enhanced therapy susceptibility,decreased GIC sphere size,expansion,and stemness in vitro.To evaluate the tumor-suppressive function of miR-182 in vivo,we synthesized miR-182-based spherical nucleic acids(182-SNAs);i.e.,gold nanoparticles covalently functionalized with mature miR-182 duplexes.Intravenously administered 182-SNAs penetrated the bloodbrain/blood-tumor barriers(BBB/BTB)in orthotopic GBM xenografts and selectively disseminated throughout extravascular glioma parenchyma,causing reduced tumor burden and increased animal survival.Our results indicate that harnessing the anti-tumor activities of miR-182 via safe and robust delivery of 182-SNAs represents a novel strategy for therapeutic intervention in GBM. | Kouri FM Hurley LA Daniel WL Day ES Hua Y Hao L Peng CY Merkel TJ Queisser MA Ritner C Zhang H James CD Sznajder JI Chin L Giljohann DA Kessler JA Peter ME Mirkin CA Stegh AH | 2015 | 中华神经外科疾病研究杂志2015，14，2： | 14 |
| 5 | 在结肠和直肠的癌症的淋巴节点收获: 当前的考虑显示文摘 The prognostic significance of identifying lymph node(LN) metastases following surgical resection for colon and rectal cancer is well recognized and is reflected in accurate staging of the disease.An established body of evidence exists,demonstrating an association between a higher total LN count and improved survival,particularly for node negative colon cancer.In node positive disease,however,the lymph node ratios may represent a better prognostic indicator,although the impact of this on clinical treatment has yet to be universally established.By extension,strategies to increase surgical node harvest and/or laboratory methods to increase LN yield seem logical and might improve cancer staging.However,debate prevails as to whether or not these extrapolations are clinically relevant,particularly when very high LN counts are sought.Current guidelines recommend a minimum of 12 nodes harvested as the standard of care,yet the evidence for such is questionable as it is unclear whether an increasing the LN count results in improved survival.Findings from modern treatments,including down-staging in rectal cancer using pre-operative chemoradiotherapy,paradoxically suggest that lower LN count,or indeed complete absence of LNs,are associated with improved survival;implying that using a specific number of LNs harvested as a measure of surgical quality is not always appropriate.The pursuit of a sufficient LN harvest represents good clinical practice;however,recent evidence shows that the exhaustive searching for very high LN yields may be unnecessary and has little in? uence on modern approaches to treatment. | James R McDonald Andrew G Renehan Sarah T O’Dwyer Najib Y Haboubi | 2012 | World Journal of Gastrointestinal Surgery2012，4，1： | 8 |
| 6 | Difficult biliary cannulation: Historical perspective, practical updates, and guide for the endoscopist显示文摘Despite improvements in endoscopic technologies and accessories, development of advanced endoscopy fellowship programs, and advances in ancillary imaging techniques, biliary cannulation in endoscopic retrograde cholangiopancreatography(ERCP) can still be unsuccessful in up to 20% of patients, even in referral centers. Once cannulation has been deemed to be difficult, the risk of post-ERCP pancreatitis and technical failure inherently increases. A number of factors, including endoscopist experience and patient anatomy, have been associated with difficult biliary cannulation, but predicting a case of difficult cannulation a priori is often not possible. Numerous techniques such as pancreatic guidewire and stenting, early pre-cut, and rendezvous may be employed when standard approaches fail. Data regarding the rate of success and adverse events of these techniques have been variable, though most studies suggest that pancreatic duct stenting generally reduces the rate of post-ERCP pancreatitis in instances of difficult biliary cannulation. Here we provide a review on difficult biliary cannulation and discuss how the choice of which techniques to employ and how to best employ them should be individualized and take into account the skill of the endoscopist, the disorder being treated, the anatomy of the patient, and the available biomedical literature. | Rani Berry James Y Han James H Tabibian | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，1： | 8 |
| 7 | MicroRNAs in pancreatic ductal adenocarcinoma显示文摘Ductal adenocarcinoma of the pancreas is a lethal cancer for which the only chance of long-term survival belongs to the patient with localized disease in whom a potentially curative resection can be done. Therefore, biomarkers for early detection and new therapeutic strategies are urgently needed. miRNAs are a recently discovered class of small endogenous non-coding RNAs of about 22 nucleotides that have gained attention for their role in downregulation of mRNA expression at the post-transcriptional level. miRNAs regulate proteins involved in critical cellular processes such as differentiation, proliferation, and apoptosis. Evidence suggests that deregulated miRNA expression is involved in carcinogenesis at many sites, including the pancreas. Aberrant expression of miRNAs may upregulate the expression of oncogenes or downregulate the expression of tumor suppressor genes, as well as play a role in other mechanisms of carcinogenesis. The purpose of this review is to summarize our knowledge of deregulated miRNA expression in pancreatic cancer and discuss the implication for potential translation of this knowledge into clinical practice. | Jong Y Park James Helm Domenico Coppola Donghwa Kim Mokenge Malafa Seung Joon Kim | 2011 | World Journal of Gastroenterology2011，17，7： | 7 |
| 8 | Randomised controlled trial comparing modified Sano's and narrow band imaging international colorectal endoscopic classifications for colorectal lesions显示文摘AIM To assess the utility of modified Sano′s(MS) vs thenarrow band imaging international colorectal endoscopic(NICE) classification in differentiating colorectal polyps.METHODS Patients undergoing colonoscopy between 2013 and 2015 were enrolled in this trial.Based on the MS or the NICE classifications,patients were randomised for real-time endoscopic diagnosis.This was followed by biopsies,endoscopic or surgical resection.The endoscopic diagnosis was then compared to the final(blinded) histopathology.The primary endpoint was the sensitivity(Sn),specificity(Sp),positive predictive value(PPV) and negative predictive value(NPV) of differentiating neoplastic and non-neoplastic polyps(MSⅡ/Ⅱo/Ⅲa/Ⅲb vs I or NICE 1 vs 2/3).The secondary endpoints were 'endoscopic resectability'(MSⅡ/Ⅱo/Ⅲa vs Ⅰ/Ⅲb or NICE 2 vs 1/3),NPV for diminutive distal adenomas and prediction of post-polypectomy surveillance intervals.RESULTS A total of 348 patients were evaluated.The Sn,Sp,PPV and NPV in differentiating neoplastic polyps from non-neoplastic polyps were,98.9%,85.7%,98.2% and 90.9% for MS;and 99.1%,57.7%,95.4% and 88.2% for NICE,respectively.The area under the receiver operating characteristic curve(AUC) for MS was 0.92(95%CI:0.86-0.98);and AUC for NICE was 0.78(95%CI:0.69,0.88).The Sn,Sp,PPV and NPV in predicting 'endoscopic resectability' were 98.9%,86.1%,97.8% and 92.5% for MS;and 98.6%,66.7%,94.7% and 88.9% for NICE,respectively.The AUC for MS was 0.92(95%CI:0.87-0.98);and the AUC for NICE was 0.83(95%CI:0.75-0.90).The AUC values were statistically different for both comparisons(P = 0.0165 and P = 0.0420,respectively).The accuracy for diagnosis of sessile serrated adenoma/polyp(SSA/P) with high confidence utilizing MS classification was 93.2%.The differentiation of SSA/P from other lesions achieved Sp,Sn,PPV and NPV of 87.2%,91.5%,89.6% and 98.6%,respectively.The NPV for predicting adenomas in diminutive rectosigmoid polyps(n = 150) was 96.6% and 95% with MS and NICE respectively.The calculated accuracy of post-polypectomy surveillance for MS group was 98.2%(167 out of 170) and for NICE group was 92.1%(139 out of 151).CONCLUSION The MS classification outperformed the NICE classification in differentiating neoplastic polyps and predicting endoscopic resectability.Both classifications met ASGE PIVI thresholds. | Leonardo Zorrón Cheng Tao Pu Kuan Loong Cheong Doreen Siew Ching Koay Sze Pheh Yeap Amanda Ovenden Mahima Raju Andrew Ruszkiewicz Philip W Chiu James Y Lau Rajvinder Singh | 2018 | World Journal of Gastrointestinal Endoscopy2018，10，9： | 4 |
| 9 | Gastric intestinal metaplasia is associated with gastric dysplasia but is inversely correlated with esophageal dysplasia显示文摘AIM To determine which clinical factors might be associated with gastric intestinal metaplasia(IM) in a North American population.METHODS Pathology and endoscopy databases at an academicmedical center were reviewed to identify patients with and without gastric IM on biopsies for a retrospective cohort study. Patient demographics, insurance status, and other clinical factors were reviewed.RESULTS Four hundred and sixty-eight patients with gastric IM(mean age: 61.0 years ± 14.4 years, 55.5% female) and 171 without gastric IM(mean age: 48.8 years ± 20.8 years, 55.0% female) were compared. The endoscopic appearance of atrophic gastritis correlated with finding gastric IM on histopathology(OR = 2.05, P = 0.051). Gastric IM was associated with histologic findings of chronic gastritis(OR = 2.56, P < 0.001), gastric ulcer(OR = 6.97, P = 0.015), gastric dysplasia(OR = 6.11, P = 0.038), and gastric cancer(OR = 6.53, P = 0.027). Histologic findings of Barrett's esophagus(OR = 0.28, P = 0.003) and esophageal dysplasia(OR = 0.11, P = 0.014) were inversely associated with gastric IM. Tobacco use(OR = 1.73, P = 0.005) was associated with gastric IM.CONCLUSION Patients who smoke or have the endoscopic finding of atrophic gastritis are more likely to have gastric IM and should have screening gastric biopsies during esophagogastroduodenoscopy(EGD). Patients with gastric IM are at increased risk for having gastric dysplasia and cancer, and surveillance EGD with gastric biopsies in these patients might be reasonable. | Justin M Gomez James T Patrie Wissam Bleibel Jeanetta W Frye Bryan G Sauer Vanessa M Shami Edward B Stelow Christopher A Moskaluk Andrew Y Wang | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，2： | 3 |
| 10 | Laparoscopic resection of gastrointestinal stromal tumors:Does laparoscopic surgery provide an adequate oncologic resection?显示文摘Gastrointestinal stromal tumors (GISTs) are rare tumors of the GI tract.Surgical resection remains the mainstay of non-metastatic disease.However,the ability to provide an adequate oncologic resection using laparoscopic surgery is still an area of debate.This is a thorough review of the current literature,looking particularly at the use of laparoscopic surgery for larger GISTs and the long-term oncologic outcomes compared to the results of open surgery.Laparoscopic resections provide an adequate oncologic result for GISTs of all sizes,including those greater than 5 cm in size. | Joseph J Kim James Y Lim Scott Q Nguyen | 2017 | World Journal of Gastrointestinal Endoscopy2017，9，9： | 3 |

| 12 | 新一代渴望导管: 在肺的栓塞的处理的可行性显示文摘 AIM: To report our preliminary experience with a new generation aspiration catheter in the treatment of symptomatic pulmonary embolism(PE). METHODS: A retrospective database search for pulmonary artery embolectomy since introduction of the Pronto.035' and XL extraction catheter(Vascular Solutions, Minneapolis, MN) at our institution in 10/2009 was performed. Ten consecutive patients were identified in which the Pronto.035' or XL catheter was used between 01/2010 and 03/2013. All patients were referred for catheter based embolectomy due to contraindications to systemic lysis, or for being in such a critical clinical condition that immediate percutaneous treatment deemed warranted. The computed tomography(CT) right to left heart ratio as predictor for the severity of the PE was retrospectively evaluated on standard axial views. The difference between pre- and post-procedure pulmonary pressure measures was taken to assess the procedural effect.RESULTS: Extensive PE was confirmed angiographically in all patients. Measured right- to left ventricle(RV/LV) ratios were elevated beyond one in seven of the eight available CTs. Acute procedural success defined as clinical removal of visible thrombus and improvement in mean pulmonary artery pressure was seen in all recorded patients(n = 8), the mean pulmonary pressures declined from a median(range) of 35.5(19-46) to 23(10-37, P = 0.008) mmHg. Neither death nor other complications occurred intra- or immediately periprocedural, yet short term mortality within 30 d was found in 6 out of 9 patients, one patient was lost in follow up. The cause of death within 30 d in the 6 patients was identified as: Circulatory failure in direct connection with the PE(n = 2), stroke, sepsis, or succumbing to malignancy in a hospice setting(n = 2). CONCLUSION: Success in thrombus removal with improved pulmonary hypertension and systemic hypotension suggests this aspiration technique to be effective. Aspiration catheters should be part of further trials. | Wolf E Heberlein Mollie E Meek Omar Saleh James C Meek Shelly Y Lensing William C Culp | 2013 | World Journal of Radiology2013，5，11： | 2 |
