2Up-regulation of mitochondrial chaperone TRAP1 in ulcerative colitis associated colorectal cancer显示文摘AIM:To characterize tumor necrosis factor receptorassociated protein 1(TRAP1)expression in the progression of ulcerative colitis(UC)-associated colorectal cancer.METHODS:Chronic UC is an inflammatory bowel disease that predisposes to colorectal cancer.Immunohistochemical analysis was used to evaluate TRAP1expression on tissue microarrays containing colonic tissues from 42 UC progressors(patients with cancer or dysplasia)and 38 non-progressors(dysplasia/cancer free patients).Statistical analyses of the TRAP1immunohistochemistry staining were performed using Graph Pad Prism.Differences in the TRAP1 level between non-progressors and progressors were tested for statistical significance using the Mann-Whitney test.Receiver operating characteristic curve method was used to quantify marker performance in distinguishing diseased cases from controls.RESULTS:TRAP1 was up-regulated in the colon tissues from UC progressors,but not in the colon tissues from UC non-progressors.Moreover,up-regulation of TRAP1 preceded the neoplastic changes:it was present in both the dysplastic and non-dysplastic tissues of UC progressors.When TRAP1 staining in rectal tissue was used as a diagnostic marker,it could distinguish progressors from non-progressors with 59%sensitivity and 80%specificity.Our study further showed that the increase of TRAP1 expression positively correlated with the degree of inflammation in the colorectal cancer tissues,which could be related to the increased oxidation present in the colonic mucosa from UC progressors.We then investigated the cellular proteome changes underlying oxidative stress,and found that oxidative stress could induce up-regulation of TRAP1 along with several other negative modulators of apoptosis.CONCLUSION:These results suggest that oxidative stress in long standing UC could lead to the increase of cytoprotective protein TRAP1,which in turn could promote cancer progression by preventing or protecting the oxidative damaged epithelial cells from undergoing apoptosis.TRAP1 could be a potential diagnostic marker for UC associated colorectal cancer.Ru Chen Sheng Pan Keith Lai Lisa A Lai David A Crispin Mary P Bronner Teresa A Brentnall 2014World Journal of Gastroenterology2014,20,45:9

8Oncogenic fingerprint of epidermal growth factor receptor pathway and emerging epidermal growth factor receptor blockade resistance in colorectal cancer显示文摘Epidermal growth factor receptor(EGFR) has been an attractive target for treatment of epithelial cancers, including colorectal cancer(CRC). Evidence from clinical trials indicates that cetuximab and panitumumab(antiEGFR monoclonal antibodies) have clinical activity in patients with metastatic CRC. The discovery of intrinsic EGFR blockade resistance in Kirsten RAS(KRAS)-mutant patients led to the restriction of anti-EGFR antibodies to KRAS wild-type patients by Food and Drug Administration and European Medicine Agency. Studies have since focused on the evaluation of biomarkers to identify appropriate patient populations that may benefit from EGFR blockade. Accumulating evidence suggests that patients with mutations in EGFR downstream signaling pathways including KRAS, BRAF, PIK3CA and PTEN could be intrinsically resistant to EGFR blockade. Recent whole genome studies also suggest that dynamic alterations in signaling pathways downstream of EGFR leads to distinct oncogenic signatures and subclones which might have some impact on emerging resistance in KRAS wild-type patients. While anti-EGFR monoclonal antibodies have a clear potential in the management of a subset of patients with metastatic CRC, further studies are warranted to uncover exact mechanisms related to acquired resistance to EGFR blockade.Zain A Sobani Ashwin Sawant Mikram Jafri Amit Keith Correa Ibrahim Halil Sahin 2016World Journal of Clinical Oncology2016,7,5:3
9光动力疗法治疗非小细胞肺癌显示文摘光动力疗法被越来越多地应用于治疗胸部恶性肿瘤。对于早期非小细胞肺癌(如支气管腔内肺癌)、X线检查阴性或同时性原发癌,光动疗法可作为主要治疗手段进行腔内根治性治疗。作为单一根治疗法,光动力疗法是治疗支气管镜可见≤1 cm且无软骨外浸润的肺部肿瘤的最有效方法。对于晚期非小细胞癌患者,光动力治疗可以作为综合根治疗法的一部分,用于减轻阻塞性支气管内病变,增加可手术性或缩小所需手术范围。本文对现有发表的应用光动力疗法治疗至少10例以上非小细胞肺癌病例的研究文献进行综述,提出了光动力疗法应用的治疗建议并进行了总结。Charles B Simone II Joseph S Friedberg Eli Glatstein James P Stevenson Daniel H Sterman Stephen M Hahn Keith A Cengel 袁光金 李金銮 朱宇熹 凌扬 2013国际病理科学与临床杂志2013,33,3:3
10Stratification of outcomes for mucinous appendiceal adenocarcinoma with peritoneal metastasis by histological grade显示文摘AIM To investigate the importance of a three-tiered histologic grade on outcomes for patients with mucinous appendiceal adenocarcinoma(MAA).METHODS Two hundred and sixty-five patients with MAA undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy were identified from a prospective database from 2004 through 2014. All pathology was reviewed by our gastrointestinal subspecialty pathologists and histological grade was classified as well-differentiated, moderately differentiated, and poorly differentiated. Survival analysis was performed using Cox proportional hazards regression.RESULTS There were 201(75.8%) well-, 45(16.9%) moderatelyand 19(7.2%) poorly-differentiated tumors. Histological grade significantly stratified the 5-year overall survival(OS), 94%, 71% and 30% respectively(P < 0.001) as well as the 5-year disease-free survival(DFS) 66%, 21% and 0%, respectively(P < 0.001). Independent predictors of DFS included tumor grade(HR = 1.78, 95%CI: 1.21-2.63, P = 0.008), lymph node involvement(HR = 0.33, 95%CI: 0.11-0.98, P < 0.02), previous surgical score(HR = 1.31, 95%CI: 1.1-1.65, P = 0.03) and peritoneal carcinomatosis index(PCI)(HR = 1.05, 95%CI: 1.02-1.08, P = 0.002). Independent predictors of OS include tumor grade(HR = 2.79, 95%CI: 1.26-6.21, P = 0.01), PCI(HR = 1.10, 95%CI: 1.03-1.16, P = 0.002), and complete cytoreduction(HR = 0.32, 95%CI: 0.11-0.92, P = 0.03). Tumor grade and PCI were the only independent predictors of both DFS and OS. Furthermore, histological grade and lymphovascular invasion stratified the risk of lymph node metastasis into a low(6%) and high(40%) risk groups. CONCLUSION Our data demonstrates that moderately differentiated MAA have a clinical behavior and outcome that is distinct from well-and poorly-differentiated MAA. The threetier grade classification provides improved prognostic stratification and should be incorporated into patient selection and treatment algorithms.Travis Edward Grotz Richard E Royal Paul F Mansfield Michael James Overman Gary N Mann Kristen Ashlee Robinson Karen A Beaty Safiea Rafeeq Auerlio Matamoros Michelle W Taggart Keith Francis Fournier 2017World Journal of Gastrointestinal Oncology2017,9,9:2

12Para-aortic lymph node involvement should not be a contraindication to resection of pancreatic ductal adenocarcinoma显示文摘BACKGROUND Para-aortic lymph nodes(PALN)are found in the aortocaval groove and they are staged as metastatic disease if involved by pancreatic ductal adenocarcinoma(PDAC).The data in the literature is conflicting with some studies having associated PALN involvement with poor prognosis,while others not sharing the same results.PALN resection is not included in the standard lymphadenectomy during pancreatic resections as per the International Study Group for Pancreatic Surgery and there is no consensus on the management of these cases.AIM To investigate the prognostic significance of PALN metastases on the oncological outcomes after resection for PDAC.METHODS This is a retrospective cohort study of data retrieved from a prospectively maintained database on consecutive patients undergoing pancreatectomies for PDAC where PALN was sampled between 2011 and 2020.Statistical comparison of the data between PALN+and PALN-subgroups,survival analysis with the Kaplan-Meier method and risk analysis with univariable and multivariable time to event Cox regression analysis were performed,specifically assessing oncological outcomes such as median overall survival(OS)and disease-free survival(DFS).RESULTS 81 cases had PALN sampling and 17(21%)were positive.Pathological N stage was significantly different between PALN+and PALN-patients(P=0.005),while no difference was observed in any of the other characteristics.Preoperative imaging diagnosed PALN positivity in one case.OS and DFS were comparable between PALN+and PALN-patients with lymph node positive disease(OS:13.2 mo vs 18.8 mo,P=0.161;DFS:13 mo vs 16.4 mo,P=0.179).No difference in OS or DFS was identified between PALN positive and negative patients when they received chemotherapy either in the neoadjuvant or in the adjuvant setting(OS:23.4 mo vs 20.6 mo,P=0.192;DFS:23.9 mo vs 20.5 mo,P=0.718).On the contrary,when patients did not receive chemotherapy,PALN disease had substantially shorter OS(5.5 mo vs 14.2 mo;P=0.015)and DFS(4.4 mo vs 9.8 mo;P<0.001).PALN involvement was not identified as an independent predictor for OS after multivariable analysis,while it was for DFS doubling the risk of recurrence.CONCLUSION PALN involvement does not affect OS when patients complete the indicated treatment pathway for PDAC,surgery and chemotherapy,and should not be considered as a contraindication to resection.Rupaly Pande Shafiq Chughtai Manish Ahuja Rachel Brown David C Bartlett Bobby V Dasari Ravi Marudanayagam Darius Mirza Keith Roberts John Isaac Robert P Sutcliffe Nikolaos A Chatzizacharias 2022World Journal of Gastrointestinal Surgery2022,14,5:2
13Neuromuscular scoliosis and pelvic fixation in 2015: Where do we stand?显示文摘Neuromuscular scoliosis is a challenging problem to treat in a heterogeneous patient population. When thedecision is made for surgery the surgeon must select a technique employed to correct the curve and achieve the goals of surgery, namely a straight spine over a level pelvis. Pre-operatively the surgeon must ask if pelvic fixation is worth the extra complications and infection risk it introduces to an already compromised host. Since the advent of posterior spinal fusion the technology used for instrumentation has changed drastically. However, many of the common problems seen with the unit rod decades ago we are still dealing with today with pedicle screw technology. Screw cut out, pseudoarthrosis, non-union, prominent hardware, wound complications, and infection are all possible complications when extending a spinal fusion construct to the pelvis in a neuromuscular scoliosis patient. Additionally, placing pelvic fixation in a neuromuscular patient results in extra blood loss, greater surgical time, more extensive dissection with creation of a deep dead space, and an incision that extends close to the rectum in patients who are commonly incontinent. Balancing the risk of placing pelvic fixation when the benefit, some may argue, is limited in non-ambulating patients is difficult when the literature is so mottled. Despite frequent advancements in technology issues with neuromuscular scoliosis remain the same and in the next 10 years we must do what we can to make safe neuromuscular spine surgery a reality.Jason B Anari David A Spiegel Keith D Baldwin 2015World Journal of Orthopedics2015,6,8:2

17Lymphoepithelial cysts and cystic lymphangiomas: Underrecognized benign cystic lesions of the pancreas显示文摘AIM: To identify their diagnostic and prognostic clinical characteristics in a large series.METHODS: Retrospective review of clinicopathologic and imaging characteristics of patients diagnosed with lymphoepithelial cysts and cystic lymphangiomas of the pancreas at Massachusetts General Hospital.RESULTS: Twelve patients were identified between 1/1/1997 and 8/1/2007. Their median age was 55.5 years(range 19-78 years), and 6 were females. The le-sion was incidentally discovered in half of the patients.Contrast enhanced computed tomography demonstrat-ed that the cysts had thin walls, without calcifications, pancreatic duct dilation or pancreatic parenchyma inva-sion. Endoscopic ultrasound with fine needle aspiration(EUS/FNA) confirmed the diagnosis of a lymphoepithe-lial cyst in 3 patients, one of whom was spared an op-eration and continues to do well after 6 years. Eleven patients had a resection: 3 pancreaticoduodenecto-mies, 7 distal pancreatectomies, and 1 enucleation. The median size of the cysts was 3 cm(range 2-20 cm). At a median follow-up of 57 mo no recurrences or other pancreas-related conditions occurred.CONCLUSION: Lymphoepithelial cysts and cystic lymphangiomas of the pancreas can be diagnosed with a combination of contrast-enhanced computed tomog-raphy scans and EUS/FNA. If the lesion is asymptom-atic, an operation might be avoided.Ioannis T Konstantinidis Avinash Kambadakone Onofrio A Catalano Dushyant V Sahani Vikram Deshpe David G Forcione Jennifer A Wargo Carlos Fernandez-del Castillo Keith D Lillemoe Andrew L Warshaw Cristina R Ferrone 2014World Journal of Gastrointestinal Surgery2014,6,7:2
