2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
3Medically unexplained dyspnea:psychophysiological characteristics and role of breathing therapy显示文摘Background Medically unexplained dyspnea occurs commonly in medical settings and remains poorly understood. This study was conducted to investigate the psychophysiological characteristics of medically unexplained dyspnea and the efficacy of breathing retraining for these patients. Methods A group of patients with medically unexplained dyspnea were compared to patients with a variety of organic lung diseases and healthy subjects. In another group of patients,the influence of breathing therapy on complaints,anxiety, and breath-holding was evaluated for an average of 1.5 years. Results Patients with medically unexplained dyspnea reported more intense dyspnea than patients with a variety of organic lung diseases. Additionally,they were anxious and presented a broad range of symptoms in daily life and under challenge,for instance voluntary hyperventilation. More than one third of them qualified for panic disorder. They had shorter breath-holding time at rest,less increase in breath-holding time and higher chances of showing a “paradoxical” decrease of breath-holding time after hyperventilation. A combination of PaO2,forced expiratory volume in one second (FEV1),and anxiety measures distinguished them from organic dyspnea. Breathing retraining profoundly improved their symptoms and decreased the level of state and trait anxiety. Moreover,they better tolerated the voluntary hyperventilation and the symptoms induced were also markedly decreased after therapy. Breath-holding time was prolonged and PetCO2 in a representative group of patients increased. Conclusions Patients with medically unexplained dyspnea appear to have the feature of a “psychosomatic” patient: an anxious patient with a wide variety of symptoms of different organ systems that do not have an organic basis. They can be distinguished from organic dyspnea using a small set of physiological and psychological measures. Breathing retraining turns out to be an effective therapy for those “difficult to treat patients”.韩江娜 朱元珏 李舜伟 雒冬梅 胡征 Van Diest I De Peuter S Van de Woestijne KP Van den Bergh O 2004Chinese Medical Journal2004,,1:10
4Acute necrotizing pancreatitis as fi rst manifestation of primary hyperparathyroidism显示文摘We report the case of a female patient with severe acute necrotizing pancreatitis associated with hypercalcemia as first manifestation of primary hyperparathyroidism caused by a benign parathyroid adenoma.Initially the acute pancreatitis was treated conservatively.The patient subsequently underwent surgical resection of the parathyroid adenoma and surgical clearance of a large infected pancreatic pseudocyst.Although the association of parathyroid adenoma-induced hypercalcemia and acute pancreatitis is a known medical entity,it is very uncommon.The pathophysiology of hypercalcemia-induced acute pancreatitis is therefore not well known,although some mechanisms have been proposed.It is important to treat the provoking factor.Therefore,the cause of hypercalcemia should be identif ied early.Surgical resection of the parathyroid adenoma is the ultimate therapy.Jeroen I Lenz Jimmy M Jacobs Bart Op de Beeck Ivan A Huyghe Paul A Pelckmans Tom G Moreels 2010World Journal of Gastroenterology2010,16,23:9
5Titanium dioxide induced inflammation in the small intestine显示文摘AIM:To investigate the effects of titanium dioxide (TiO2) nanoparticles (NPTiO 2 ) and microparticles (MPTiO 2 ) on the inflammatory response in the small intestine of mice. METHODS: Bl 57/6 male mice received distilled water suspensions containing TiO 2 (100 mg/kg body weight) as NPTiO 2 (66 nm), or MPTiO 2 (260 nm) by gavage for 10 d, once a day; the control group received only distilled water. At the end of the treatment the duodenum, jejunum and ileum were extracted for assessment of cytokines, inflammatory cells and titanium content. The cytokines interleukin (IL)-1b, IL-4, IL-6, IL-8, IL-10, IL-12, IL-13, IL-17, IL-23, tumor necrosis factor-α (TNF-α), intracellular interferon-γ (IFN-γ) and transforming growth factor-β (TGF-β) were evaluated by enzyme-linked immunosorbent assay in segments of jejunum and ileum (mucosa and underlying muscular tissue). CD4 + and CD8 + T cells, natural killer cells, and dendritic cells were evaluated in duodenum, jejunum and ileum samples fixed in 10% formalin by immuno-histochemistry. The titanium content was determined by inductively coupled plasma atomic emission spectrometry. RESULTS: We found increased levels of T CD4 + cells (cells/mm 2 ) in duodenum:NP 1240 ± 139.4, MP 1070 ± 154.7 vs 458 ± 50.39 (P < 0.01); jejunum:NP 908.4 ± 130.3, MP 813.8 ± 103.8 vs 526.6 ± 61.43 (P < 0.05); and ileum:NP 818.60 ± 123.0, MP 640.1 ± 32.75 vs 466.9 ± 22.4 (P < 0.05). In comparison to the control group, the groups receiving TiO 2 showed a statistically significant increase in the levels of the inflammatory cytokines IL-12, IL-4, IL-23, TNF-α, IFN-γ and TGF-β. The cytokine production was more pronounced in the ileum (mean ± SE):IL-12: NP 33.98 ± 11.76, MP 74.11 ± 25.65 vs 19.06 ± 3.92 (P < 0.05); IL-4: NP 17.36 ± 9.96, MP 22.94 ± 7.47 vs 2.19 ± 0.65 (P < 0.05); IL-23: NP 157.20 ± 75.80, MP 134.50 ± 38.31 vs 22.34 ± 5.81 (P < 0.05); TNFα: NP 3.71 ± 1.33, MP 5.44 ± 1.67 vs 0.99± 019 (P < 0.05); IFNγ: NP 15.85 ± 9.99, MP 34.08 ± 11.44 vs 2.81 ± 0.69 (P < 0.05); and TGF-β: NP 780.70 ± 318.50, MP 1409.00 ± 502.20 vs 205.50 ± 63.93 (P < 0.05). CONCLUSION:Our findings indicate that TiO2 particles induce a Th1-mediated inflammatory response in the small bowel in mice.Carolina Maciel Nogueira Walter Mendes de Azevedo Maria Lucia Zaidan Dagli Sérgio Hiroshi Toma AndréZonetti de Arruda Leite Maria Laura Lordello Iêda Nishitokukado Carmen Lúcia Ortiz-Agostinho Maria IrmaSeixas Duarte Marcelo Alves Ferreira Aytan Miranda Sipahi 2012World Journal of Gastroenterology2012,18,34:8
6Breath test for differential diagnosis between small intestinal bacterial overgrowth and irritable bowel disease:An observation on non-absorbable antibiotics显示文摘AIM: To estimate the prevalence of small intestine bacterial overgrowth (SIBO) among patients with an earlier diagnosis of irritable bowel disease (IBS) in our geographical area, and to collect information on the use of locally acting non-absorbable antibiotics in the management of SIBO. METHODS: A non-interventional study was conducted in 73 consecutive patients with a symptom-based diagnosis.. RESULTS: When the patients underwent a 'breath test', 33 (45.2%) showed the presence of a SIBO. After treatment with rifaximin 1200 mg/d for seven days in 32 patients, 19 (59.4%) showed a negative 'breath test' one week later as well as a significant reduction of symptoms, thus confirming the relationship between SIBO and many of the symptoms claimed by patients. In the other 13 patients, 'breath test' remained positive, and a further cycle of treatment with ciprofloxacin 500 mg/d was given for 7 additional days, resulting in a negative 'breath test' in one patient only. CONCLUSION: (1) about half of the patients with a symptomatic diagnosis of IBS have actually SIBO, which is responsible for most of the symptoms attributed to IBS; (2) only a 'breath test' with lactulose (or with glucose in subjects with an intolerance to lactose) can provide a differential diagnosis between IBS and SIBO, with almost identical symptoms; and (3) the use of non-absorbable antibiotics may be useful to reduce the degree of SIBO and related symptoms; it must be accompanied, however, by the correction of the wrong alimentary habits underlying SIBO.I Esposito A de Leone G Di Gregorio S Giaquinto L de Magistris A Ferrieri G Riegler 2007World Journal of Gastroenterology2007,13,45:8
7Sessile serrated adenomas:Demographic,endoscopic and pathological characteristics显示文摘AIM:To study the demographic and endoscopic characteristics of patients with sessile serrated adenoma(SSA) in a single center.METHODS:Patients with SSA were identified by review of the pathology database of Mayo Clinic Arizona from 2005 to 2007.A retrospective chart review was performed to extract data on demographics,polyp characteristics,presence of synchronous adenomatous polyps or cancer,polypectomy methods,and related complications.RESULTS:One hundred and seventy-one(2.9%) of all patients undergoing colonoscopy had a total of 226 SSAs.The mean(SE) size of the SSAs was 8.1(0.4) mm;42% of SSAs were ≤ 5 mm,and 69% were ≤ 9 mm.Fifty-one per cent of SSAs were located in the cecum or ascending colon.Approximately half of the patients had synchronous polyps of other histological types,including hyperplastic and adenomatous polyps.Synchronous adenocarcinoma was present in seven(4%) cases.Ninety-seven percent of polyps were removed by colonoscopy.CONCLUSION:Among patients with colon polyps,2.9% were found to have SSAs.Most of the SSAs were located in the right side and were safely managed by colonoscopy.Suryakanth R Gurudu Russell I Heigh Giovanni De Petris Evelyn G Heigh Jonathan A Leighton Shabana F Pasha Isaac B Malagon Ananya Das 2010World Journal of Gastroenterology2010,16,27:7
8Chronic stress sensitizes rats to pancreatitis induced by cerulein:Role of TNF-α显示文摘AIM:To investigate chronic stress as a susceptibility factor for developing pancreatitis,as well as tumor necrosis factor-α (TNF-α) as a putative sensitizer.METHODS:Rat pancreatic acini were used to analyze the influence of TNF-α on submaximal (50 pmol/L) cholecystokinin (CCK) stimulation.Chronic restraint (4 h every day for 21 d) was used to evaluate the effects of submaximal (0.2 μg/kg per hour) cerulein stimulation on chronically stressed rats.RESULTS:In vitro exposure of pancreatic acini toTNF-α disorganized the actin cytoskeleton.This was further increased by TNF-α/CCK treatment,which additionally reduced amylase secretion,and increased trypsin and nuclear factor-κB activities in a protein-kinase-C δ and ε-dependent manner.TNF-α/CCK also enhanced caspases' activity and lactate dehydrogenase release,induced ATP loss,and augmented the ADP/ATP ratio.In vivo,rats under chronic restraint exhibited elevated serum and pancreatic TNF-α levels.Serum,pancreatic,and lung inflammatory parameters,as well as caspases' activity in pancreatic and lung tissue,were substantially enhanced in stressed/cerulein-treated rats,which also experienced tissues' ATP loss and greater ADP/ATP ratios.Histological examination revealed that stressed/cerulein-treated animals developed abundant pancreatic and lung edema,hemorrhage and leukocyte infiltrate,and pancreatic necrosis.Pancreatitis severity was greatly decreased by treating animals with an anti-TNF-αantibody,which diminished all inflammatory parameters,histopathological scores,and apoptotic/necrotic markers in stressed/cerulein-treated rats.CONCLUSION:In rats,chronic stress increases susceptibility for developing pancreatitis,which involves TNF-α sensitization of pancreatic acinar cells to undergo injury by physiological cerulein stimulation.Marcelo G Binker Andres A Binker-Cosen Daniel Richards Herbert Y Gaisano Rodica H de Cosen Laura I Cosen-Binker 2010World Journal of Gastroenterology2010,16,44:7
9Quantitative Study on Nonmetallic Inclusion Particles in Steels by Automatic Image Analysis With Extreme Values Method显示文摘The presence of nonmetallic inclusion particles which appear during steelmaking process is harmful to the properties of steels,which is mainly as a function of some aspects such as size,volume fraction,shape,and distribution of these particles.The automatic image analysis technique is one of the most important tools for the quantitative determination of these parameters.The classical Student approach and the Extreme Values Method(EVM) were used for the inclusion size and shape determination and the evaluation of distance between the inclusion particles.The results thus obtained indicated that there were significant differences in the characteristics of the inclusion particles in the analyzed products.Both methods achieved results with some differences,indicating that EVM could be used as a faster and more reliable statistical methodology.Cássio Barbosa José Brant de Campos Jneo Lopes do Nascimento Iêda Maria Vieira Caminha 2009Journal of Iron and Steel Research(International)2009,16,4:7

11The magnetic response of graphene split-ring metamaterials显示文摘Graphene has emerged as a promising platform for THz plasmonics,allowing high confinement,long lifetimes and fast electrical tunability.Here,we predict a strong magnetic dipole response by graphene split nanorings at THz frequencies,allowing the attainment of metamaterials with a high degree of field confinement(approximately one hundredth of the excitation wavelength)that is not reachable with conventional noble metals.The magnetic response of highly doped graphene split-rings in the far-infrared is much stronger than that displayed by gold structures of similar thicknesses.We further explored stacked graphene layers as a practical way of producing high-frequency magnetism in thin,electrically tunable metamaterials.Our results support the great potential of using graphene to achieve electrically tunable magnetic metamaterials.Nikitas Papasimakis Sukosin Thongrattanasiri Nikolay I Zheludev FJ Garcıa de Abajo 2013Light(Science & Applications)2013,2,1:5
12Roscovitine sensitizes breast cancer cells to TRAIL-induced apoptosis through a pleiotropic mechanism显示文摘肿瘤坏死因素(TNF ) 联系了导致 apoptosis ligand (TRAIL/APO2L ) 是在血缘的死亡受体的约会之上导致 apoptosis 的 TNF 基因总科的一个成员。当小道对正常房间相对无毒时,它有选择地在许多转变房间导致 apoptosis。不过,胸肿瘤房间对小道的效果特别地抵抗。这里,我们报导在有 cyclin 依赖的 kinase 禁止者 roscovitine 的联合,落后于的暴露在检验的小道抵抗的乳癌房间线的多数导致了显著 apoptosis。Roscovitine 便于小道导致死亡的发信号的复杂形成和 caspase-8 的激活。FLICE 禁止的蛋白质是的 cFLIP (L) 和 cFLIP 显著地下面调整的列在后面暴露到 roscovitine 并且,确实由 siRNA 的 cFLIP isoforms 击倒敏化的胸肿瘤房间到导致小道的 apoptosis。另外,我们证明 roscovitine 强烈在胸肿瘤房间压制了 Mcl-1 表示和起来调整的 E2F1 蛋白质层次。显著地,由 siRNA 的 Mcl-1 的 silencing 敏化胸肿瘤房间到导致小道的 apoptosis。而且,由减少的 siRNA 的 E2F1 蛋白质击倒在导致小道的 apoptosis 的 roscovitine 的敏化的效果。在摘要,我们的结果为 roscovitine 的 pro-apoptotic 影响揭示 pleitropic 机制,加亮它象在在有小道的联合的乳癌的一个反肿瘤代理人的潜力。Gustavo Ortiz-Ferrón Rosario Yerbes Adriana Eramo Ana I López-Pérez Ruggero De Maria Abelardo Lápez-Rivas 2008Cell Research2008,18,6:5
13TAT-Gap19通过抑制啮齿动物星形胶质细胞的连接蛋白43半通道发挥抗惊厥作用显示文摘越来越多的证据表明,星形胶质细胞连接蛋白43(Cx43)信号在癫痫中发挥至关重要的作用。但是,由于通过实验方法鉴别Cx43间隙连接通道(GJCs)和半通道(HCs)的技术尚不成熟,导致目前尚无法确定哪个通道在癫痫的发生中发挥更重要的作用。因此,本研究观察TAT-Gap19(Cx模拟肽)是否通过抑制Cx43半通道而非Cx43间隙连接通道影响实验诱导的啮齿动物癫痫发作。急性海马切片小鼠染料摄取实验表明,星形胶质Cx43半通道响应化学惊厥毛果芸香碱的作用而开放,并且可被TAT-Gap19抑制。体内实验中,毛果芸香碱诱导的癫痫发作及相伴随的D-丝氨酸微透析液的增长水平被Cx43半通道的抑制所抑制。此外,TAT-Gap19的抗惊厥作用被外源性D-丝氨酸给药逆转,这表明,抑制Cx43半通道可以通过降低细胞外D-丝氨酸水平来防止癫痫发作。抑制Cx43半通道的抗惊厥特性在电癫痫小鼠模型(如急性6 Hz难治性癫痫发作模型和慢性6 Hz角膜点燃模型)中得到了进一步的证实。总而言之,这些结果表明,Cx43半通道在癫痫发作中可以起到一定作用,并且有成为癫痫治疗中新型用药靶点的潜力。Walrave L Pierre A Albertini G Aourz N De Bundel D Van Eeckhaut A Vinken M Giaume C Leybaert L Smolders I 聂昊 2018神经损伤与功能重建2018,13,6:5
14Feasibility study of computed vs measured high b-value(1400 s/mm2) diffusion-weighted MR images of the prostate显示文摘AIM: To evaluate the impact of computed b = 1400 s/mm2(C-b1400) vs measured b = 1400 s/mm2(M-b1400) diffusion-weighted images(DWI) on lesion detection rate, image quality and quality of lesion demarcation using a modern 3T-MR system based on a small-field-of-view sequence(sFOV). METHODS: Thirty patients(PSA: 9.5 ± 8.7 ng/mL; 68 ± 12 years) referred for magnetic resonance imaging(MRI) of the prostate were enrolled in this study. All measurements were performed on a 3T MR system.For DWI, a single-shot EPI diffusion sequence(b = 0, 100, 400, 800 s/mm2) was utilized. C-b1400 was cal-culated voxelwise from the ADC and diffusion images. Additionally, M-b1400 was acquired for evaluation and comparison. Lesion detection rate and maximum lesion diameters were obtained and compared. Image quality and quality of lesion demarcation were rated accord-ing to a 5-point Likert-type scale. Ratios of lesion-to-bladder as well as prostate-to-bladder signal intensity(SI) were calculated to estimate the signal-to-noise-ratio(SNR). RESULTS: Twenty-four lesions were detected on M-b1400 images and compared to C-b1400 images. C-b1400 detected three additional cancer suspicious lesions. Overall image quality was rated significantly better and SI ratios were significantly higher on C-b1400(2.3 ± 0.8 vs 3.1 ± 1.0, P < 0.001; 5.6 ± 1.8 vs 2.8 ± 0.9, P < 0.001). Comparison of lesion size showed no significant differences between C- and M-b1400(P = 0.22). CONCLUSION: Combination of a high b-value extrap-olation and sFOV may contribute to increase diagnostic accuracy of DWI without an increase of acquisition time, which may be useful to guide targeted prostate biopsies and to improve quality of multiparametric MRI(mMRI) especially under economical aspects in a pri-vate practice setting.Leonardo K Bittencourt Ulrike I Attenberger Daniel Lima Ralph Strecker Andre de Oliveira Stefan O Schoenberg Emerson L Gasparetto Daniel Hausmann 2014World Journal of Radiology2014,6,6:5

19Trends in treatment and overall survival among patients with proximal esophageal cancer显示文摘BACKGROUND The management of proximal esophageal cancer differs from that of tumors located in the mid and lower part of the esophagus due to the close vicinity of vital structures.Non-surgical treatment options like radiotherapy and definitive chemoradiation(CRT)have been implemented.The trends in(non-)surgical treatment and its impact on overall survival(OS)in patients with proximal esophageal cancer are unclear,related to its rare disease status.To optimize treatment strategies and counseling of patients with proximal esophageal cancer,it is therefore essential to gain more insight through real-life studies.AIM To establish trends in treatment and OS in patients with proximal esophageal cancer.METHODS In this population-based study,patients with proximal esophageal cancer diagnosed between 1989 and 2014 were identified in the Netherlands Cancer Registry.The proximal esophagus consists of the cervical esophagus and the upper thoracic section,extending to 24 cm from the incisors.Trends in radiotherapy,chemotherapy,and surgery,and OS were assessed.Analyses were stratified by presence of distant metastasis.Multivariable Cox proportional hazards regression analyses was performed to assess the effect of period of diagnosis on OS,adjusted for patient,tumor,and treatment characteristics.RESULTS In total,2783 patients were included.Over the study period,the use of radiotherapy,resection,and CRT in non-metastatic disease changed from 53%,23%,and 1%in 1989-1994 to 21%,9%,and 49%in 2010-2014,respectively.In metastatic disease,the use of chemotherapy and radiotherapy increased over time.Median OS of the total population increased from 7.3 mo[95%confidence interval(CI):6.4-8.1]in 1989-1994 to 9.5 mo(95%CI:8.1-10.8)in 2010-2014(logrank P<0.001).In non-metastatic disease,5-year OS rates improved from 5%(95%CI:3%-7%)in 1989-1994 to 13%(95%CI:9%-17%)in 2010-2014(logrank P<0.001).Multivariable regression analysis demonstrated a significant treatment effect over time on survival.In metastatic disease,median OS was 3.8 mo(95%CI:2.5-5.1)in 1989-1994,and 5.1 mo(95%CI:4.3-5.9)in 2010-2014(logrank P=0.26).CONCLUSION OS significantly improved in non-metastatic proximal esophageal cancer,likely to be associated with an increased use of CRT.Patterns in metastatic disease did not change significantly over time.Judith de Vos-Geelen Sandra ME Geurts Liselot BJ Valkenburg-van Iersel Evelien JM de Jong Vivianne CG Tjan-Heijnen Margreet van Putten Valery EPP Lemmens Heike I Grabsch Nadia Haj Mohammad Frank JP Hoebers Chantal V Hoge Paul M Jeene Hanneke WM van Laarhoven Tom Rozema Marije Slingerland Grard AP Nieuwenhuijzen 2019World Journal of Gastroenterology2019,25,47:2
