5直肠癌放化疗后观察等待与手术治疗的配对队列研究显示文摘目的近年对于直肠癌放化疗后临床完全缓解的患者出现了新的治疗模式。这类患者在新辅助治疗后不进行手术治疗而进行观察-等待(watch-and-wait)的随诊观察。本研究旨在通过对比放化疗后临床完全缓解的患者接受手术治疗和观察-等待方式两者的肿瘤学转归,研究观察-等待随诊方式的安全性。方法 On Co Re(直肠癌完全缓解病例肿瘤学转归)研究是在英国曼切斯特一所三级癌中心进行的配对队列研究。自2011年1月到2013年4月,收集所有年龄段、无远处转移且接受了术前化放疗(45Gy,25天,同期氟尿嘧啶化疗)的直肠腺癌病例。达到临床完全缓解的患者,进入观察-等待方式,而未获临床完全缓解的患者,在条件允许下接受手术治疗。本研究通过注册登记,同时纳入自2005年3月10日至2015年1月21日来自相邻区域的3所英国癌中心临床完全缓解而接受单纯等待-观察方式的直肠癌患者。研究采用采用1∶1配比队列,使用倾向得分匹配分析法(包括T分期、年龄和体力状态),比较患者接受单纯观察等待与手术切除的治疗转归。主要观察终点为自化放疗开始后无疾病进展生存,次要终点为总体生存以及结肠造口术后无瘤生存。本研究以更保守的P〈0.01视为差异具有统计学意义。结果共有259例患者来自曼彻斯特癌中心,228例接受手术治疗,而31例临床完全缓解患者单纯进行观察-等待。此外通过注册登记的98例患者也进入观察-等待组。观察-等待组共129位患者[中位随访33个月(IQR 19~43个月)],44例(34%)局部复发。41例无转移的局部复发患者中36例(88%)接受了补救性手术。配对分析显示(各109例),观察-等待组和手术组的3年无疾病进展生存无统计学差异[88%(95%CI 75~94)vs.78%(63~87),P=0.043]。同时3年总体生存也没有显著性差异(96%vs.87%,P=0.024)。观察-等待组的结肠造口率明显低于手术组,其3年结肠造口术后无瘤生存率为74%(95%CI 64~82),而手术组为47%(P〈0.0001)。风险比0.445(95%CI 0.31~0.63,P〈0.0001),观察-等待组较手术组的3年终生造口风险降低26%(95%CI 13~39)。结论本研究显示,确实存在一定比例的直肠癌患者可以通过观察-等待方式避免手术,免除终生造口,同时获得3年良好的肿瘤安全性。这结果提示,应从一开始就认真考虑直肠癌患者化放疗策略,观察-等待治疗作为标准治疗方式看来是可行的。研究者认为如果患者在化放疗开始后,少于14周内取得早期临床完全缓解,或者大于24周取得临床完全缓解,其复发的机会较少。此外,广泛使用45 Gy的放疗的患者的临床完全缓解率为10%~15%,更高剂量的放化疗能够将其提高到大于50%。如此高的临床完全缓解率如果能够在可接受的毒副作用范围内反复出现,那么以上两种策略就可以实现长期、持续的临床完全缓解。然而,这一观察结果还需要临床研究验证。Renehan AG Malcomson L Emsley R 张信华 2016消化肿瘤杂志(电子版)2016,8,1:27

8Evaluation of quantitative contrast harmonic imaging to assess malignancy of liver tumors:A prospective controlled two-center study显示文摘AIM: To establish the extent to which contrast enhancement with SonoVue in combination with quantitative evaluation of contrast-medium dynamics facilitates the detection of hepatic tumors. METHODS: One hundred patients with histologically confirmed malignant or benign hepatic tumor (maximum size 5 cm) were analyzed. Contrast-enhanced ultrasound (bolus injection 2.5 mL SonoVue) was carried out with intermittent breath-holding technique using a multifrequency transducer (2.5-4 MHz). Native vascularization was analyzed with power Doppler. The contrast-enhanced dynamic ultrasound investigation was carried out with contrast harmonic imaging in true detection mode during the arterial,portal venous and late phases. Mechanical index was set at 0.15. Perfusion analysis was performed by post-processing of the raw data time intensity curve (TIC) analysis. The cut-off of the gray value differences between tumor and normal liver tissue was established using Receiver Operating Characteristic (ROC) analysis 64-line multi-slice computed tomography served as reference method in all cases. Magnetic resonance tomography was used additionally in 19 cases. RESULTS: One hundred patients with 59 malignant (43 colon,5 breast,2 endocrine metastases,7 hepatocellular carcinomas and 2 kidney cancers) and 41 benign (15 hemangiomas,7 focal nodular hyperplasias,5 complicated cysts,2 abscesses and 12 circumscribed fatty changes) tumors were included. The late venous phase proved to be the most sensitive for classification of the tumor type. Fifty-eight of the 59 malignant tumors were classified as true positive,and one as false negative. This resulted in a sensitivity of 98.3%. Of the 41 benign tumors,37 were classified as true negative and 4 as false negative,which corresponds to a specificity of 90.2%. Altogether,95.0% of the diagnoses were classified as correct on the basis of the histological classification. No investigator-dependency (P = 0.23) was noted. CONCLUSION: The results show the possibility of accurate prediction of malignancy of hepatic tumors with a positive prognostic value of 93.5% using advanced contrast-enhanced ultrasound. Contrast enhancement with SonoVue in combination with quantitative evaluation of contrast-medium dynamics is a valuable tool to discriminate hepatic tumors.EM Jung DA Clevert AG Schreyer S Schmitt J Rennert R Kubale S Feuerbach F Jung 2007World Journal of Gastroenterology2007,13,47:15
9Computed tomography-guided percutaneous core needle biopsy in pancreatic tumor diagnosis显示文摘AIM: To evaluate the techniques, results, and complications related to computed tomography(CT)-guided percutaneous core needle biopsies of solid pancreatic lesions.METHODS: CT-guided percutaneous biopsies of solid pancreatic lesions performed at a cancer reference center between January 2012 and September 2013 were retrospectively analyzed. Biopsy material was collected with a 16-20 G Tru-Core needle(10-15 cm; Angiotech, Vancouver, CA) using a coaxial system and automatic biopsy gun. When direct access to the lesion was not possible, indirect(transgastric or transhepatic) access or hydrodissection and/or pneumodissection maneuvers were used. Characteristics of the patients, lesions, procedures, and histologic results were recorded using a standardized form. RESULTS: A total of 103 procedures included in the study were performed on patients with a mean age of 64.8 year(range: 39-94 year). The mean size of the pancreatic lesions was 45.5 mm(range: 15-195 mm). Most(75/103, 72.8%) procedures were performed via direct access, though hydrodissection and/or pneumodissection were used in 22.2%(23/103) of cases and indirect transhepatic or transgastric access was used in 4.8%(5/103) of cases. Histologic analysis was performed on all biopsies, and diagnoses were conclusive in 98.1%(101/103) of cases, confirming3.9%(4/103) of tumors were benign and 94.2%(97/103) were malignant; results were atypical in 1.9%(2/103) of cases, requiring a repeat biopsy to diagnose a neuroendocrine tumor, and surgical resection to confirm a primary adenocarcinoma. Only mild/moderate complications were observed in 9/103 patients(8.7%),and they were more commonly associated with biopsies of lesions located in the head/uncinate process(n =8), than of those located in the body/tail(n = 1) of the pancreas, but this difference was not significant.CONCLUSION: CT-guided biopsy of a pancreatic lesion is a safe procedure with a high success rate, and is an excellent option for minimally invasive diagnosis.Chiang J Tyng Maria Fernanda A Almeida Paula NV Barbosa Almir GV Bitencourt José Augusto AG Berg Macello S Maciel Felipe JF Coimbra Luiz Henrique O Schiavon Maria Dirlei Begnami Marcos D Guimares Charles E Zurstrassen Rubens Chojniak 2015World Journal of Gastroenterology2015,21,12:14

11Characteristics of common solid liver lesions and recommendations for diagnostic workup显示文摘Due to the widespread clinical use of imaging modalities such as ultrasonography,computed tomography and magnetic resonance imaging (MRI),previously unsuspected liver masses are increasingly being found in asymptomatic patients.This review discusses the various characteristics of the most common solid liver lesions and recommends a practical approach for diagnostic workup.Likely diagnoses include hepatocellular carcinoma (the most likely;a solid liver lesion in a cirrhotic liver) and hemangioma (generally presenting as a mass in a non-cirrhotic liver).Focal nodular hyperplasia and hepatic adenoma should be ruled out in young women.In 70% of cases,MRI with gadolinium differentiates between these lesions.Fine needle core biopsy or aspiration,or both,might be required in doubtful cases.If uncertainty persists as to the nature of the lesion,surgical resection is recommended.If the patient is known to have a primary malignancy and the lesion was found at tumor staging or follow up,histology is required only when the nature of the liver lesion is doubtful.Nimer Assy Gattas Nasser Agness Djibre Zaza Beniashvili Saad Elias Jamal Zidan 2009World Journal of Gastroenterology2009,15,26:9

14Lower baseline ALT cut-off values and HBV DNA levels better differentiate HBeAg(-) chronic hepatitis B patients from inactive chronic carriers显示文摘AIM:To determine whether new cut-off values for alanine aminotransferase(ALT)and baseline hepatitis B virus(HBV)DNA levels better differentiate HBeAg(-) chronic hepatitis B(CHB)patients from inactive chronic carriers. METHODS:Ninety-one patients[32 HBeAg(+)CHB, 19 inactive carriers and 40 HBeAg(-)CHB]were followed up for 2 years and were tested for HBV DNA levels by a PCR-based assay.ALT was tested twice during the last 6 mo using new cut-off values:ULN(upper limit of normal)30 IU/L for males,19 IU/L for females. Diagnostic accuracy,sensitivity,specificity,positive and negative predictive values were calculated by discriminant analysis. RESULTS:When using the revised ALT cut-off values, the lowest optimal HBV DNA level that differentiated HBeAg(-)CHB patients from inactive carriers was 50000 copies/mL.The diagnostic accuracy of HBV DNA to determine inactive carriers with a cut-off of 50000 copies/mL was similar to the previously recommended cut-off of 100 000 copies/mL(91%).HBV DNA levels were lower than the cut-off value in 95%of inactive carriers and in 28%of HBeAg(-)CHB patients.With ALT<30 IU/L in men and<19 IU/L in women and HBV DNA levels<100 000 copies/mL,the risk of CHB is 5%.On the other hand,if ALT values were>30 IU in men and>19 IU in women and baseline HBV DNA levels were>100000 copies/mL,the risk is 86%. CONCLUSION:New cut-off values for ALT together with HBV DNA levels proposed by AASLD(American Association for the Study of Liver Diseases)and NIH (National Institute of Health)consensus seem appropriate to characterize inactive carriers.Nimer Assy Zaza Beniashvili Agness Djibre Gattas Nasser Maria Grosovski William Nseir 2009World Journal of Gastroenterology2009,15,24:7

20Tumor-stroma ratio as prognostic factor for survival in rectal adenocarcinoma: A retrospective cohort study显示文摘AIM To evaluate the prognostic value of the tumor-stroma ratio(TSR) in rectal cancer.METHODS TSR was determined on hematoxylin and eosin stained histological sections of 154 patients treated for rectal adenocarcinoma without prior neoadjuvant treatment in the period 1996-2006 by two observers to assessreproducibility. Patients were categorized into three categories: TSR-high [carcinoma percentage(CP) ≥ 70%], TSR-intermediate(CP 40%, 50% and 60%) and TSR-low(CP ≤ 30%). The relation between categorized TSR and survival was analyzed using Cox proportional hazards model.RESULTS Thirty-six(23.4%) patients were scored as TSR-low, 70(45.4%) as TSR-intermediate and 48(31.2%) as TSRhigh. TSR had a good interobserver agreement(κ = 0.724, concordance 82.5%). Overall survival(OS) and disease free survival(DFS) were significantly better for patients with a high TSR(P = 0.01 and P = 0.02, respectively). A similar association existed for disease specific survival(P = 0.06). In multivariate analysis, patients without lymph node metastasis and an intermediate TSR had a higher risk of dying from rectal cancer(HR = 5.27, 95%CI: 1.54-18.10), compared to lymph node metastasis negative patients with a high TSR. This group also had a worse DFS(HR = 6.41, 95%CI: 1.84-22.28). An identical association was seen for OS. These relations were not seen in lymph node metastasis positive patients. CONCLUSION The TSR has potential as a prognostic factor for survival in surgically treated rectal cancer patients, especially in lymph node negative cases.René Scheer Alexi Baidoshvili Shorena Zoidze Marloes AG Elferink Annefleur EM Berkel Joost M Klaase Paul J van Diest 2017World Journal of Gastrointestinal Oncology2017,9,12:3
