| 1 | Retrospective study on mixed neuroendocrine non-neuroendocrine neoplasms from five European centres显示文摘BACKGROUND Mixed neuroendocrine non-neuroendocrine neoplasm(MiNEN)is a rare diagnosis,mainly encountered in the gastro-entero-pancreatic tract.There is limited knowledge of its epidemiology,prognosis and biology,and the best management for affected patients is still to be defined.AIM To investigate clinical-pathological characteristics,treatment modalities and survival outcomes of a retrospective cohort of patients with a diagnosis of MiNEN.METHODS Consecutive patients with a histologically proven diagnosis of MiNEN were identified at 5 European centres.Patient data were retrospectively collected from medical records.Pathological samples were reviewed to ascertain compliance with the 2017 World Health Organisation definition of MiNEN.Tumour responses to systemic treatment were assessed according to the Response Evaluation Criteria in Solid Tumours 1.1.Kaplan-Meier analysis was applied to estimate survival outcomes.Associations between clinical-pathological characteristics and survival outcomes were explored using Log-rank test for equality of survivors functions(univariate)and Cox-regression analysis(multivariable).RESULTS Sixty-nine consecutive patients identified;Median age at diagnosis:64 years.Males:63.8%.Localised disease(curable):53.6%.Commonest sites of origin:colon-rectum(43.5%)and oesophagus/oesophagogastric junction(15.9%).The neuroendocrine component was;predominant in 58.6%,poorly differentiated in 86.3%,and large cell in 81.25%,of cases analysed.Most distant metastases analysed(73.4%)were occupied only by a poorly differentiated neuroendocrine component.Ninety-four percent of patients with localised disease underwent curative surgery;53%also received perioperative treatment,most often in line with protocols for adenocarcinomas from the same sites of origin.Chemotherapy was offered to most patients(68.1%)with advanced disease,and followed protocols for pure neuroendocrine carcinomas or adenocarcinomas in equal proportion.In localised cases,median recurrence free survival(RFS);14.0 months(95%CI:9.2-24.4),and median overall survival(OS):28.6 months(95%CI:18.3-41.1).On univariate analysis,receipt of perioperative treatment(vs surgery alone)did not improve RFS(P=0.375),or OS(P=0.240).In advanced cases,median progression free survival(PFS);5.6 months(95%CI:4.4-7.4),and median OS;9.0 months(95%CI:5.2-13.4).On univariate analysis,receipt of palliative active treatment(vs best supportive care)prolonged PFS and OS(both,P<0.001).CONCLUSION MiNEN is most commonly driven by a poorly differentiated neuroendocrine component,and has poor prognosis.Advances in its biological understanding are needed to identify effective treatments and improve patient outcomes. | Melissa Frizziero Xin Wang Bipasha Chakrabarty Alexa Childs Tu V Luong Thomas Walter Mohid S Khan Meleri Morgan Adam Christian Mona Elshafie Tahir Shah Annamaria Minicozzi Wasat Mansoor Tim Meyer Angela Lamarca Richard A Hubner Juan W Valle Mairéad G McNamara | 2019 | World Journal of Gastroenterology2019，25，39： | 13 |
| 2 | Predictive value of multi-detector computed tomography for accurate diagnosis of serous cystadenoma:Radiologic-pathologic correlation显示文摘AIM:To identify multi-detector computed tomography(MDCT) features most predictive of serous cystadenomas(SCAs),correlating with histopathology,and to study the impact of cyst size and MDCT technique on reader performance.METHODS:The MDCT scans of 164 patients with surgically verified pancreatic cystic lesions were reviewed by two readers to study the predictive value of various morphological features for establishing a diagnosis of SCAs.Accuracy in lesion characterization and reader conf idence were correlated with lesion size(≤3cm or≥3cm) and scanning protocols(dedicated vs routine).RESULTS:28/164 cysts(mean size,39 mm;range,8-92mm) were diagnosed as SCA on pathology.The MDCT features predictive of diagnosis of SCA were microcystic appearance(22/28,78.6%),surface lobulations(25/28,89.3%) and central scar(9/28,32.4%).Stepwise logistic regression analysis showed that only microcystic appearance was signifi cant for CT diagnosis of SCA(P=0.0001).The sensitivity,specificity and PPV of central scar and of combined microcystic appearance and lobulations were 32.4%/100%/100% and 68%/100%/100%,respectively.The reader confidence was higher for lesions>3cm(P=0.02) and for MDCT scans performed using thin collimation(1.25-2.5mm) compared to routine 5 mm collimation exams(P>0.05).CONCLUSION:Central scar on MDCT is diagnostic of SCA but is seen in only one third of SCAs.Microcystic morphology is the most significant CT feature in diagnosis of SCA.A combination of microcystic appearance and surface lobulations offers accuracy comparable to central scar with higher sensitivity. | Anjuli A Shah Nisha I Sainani Avinash Kambadakone Ramesh Zarine K Shah Vikram Deshpande Peter F Hahn Dushyant V Sahani | 2009 | World Journal of Gastroenterology2009，15，22： | 11 |
| 3 | Systematic review of dynamization vs exchange nailing for delayed/non-union femoral fractures显示文摘AIM To analyze the literature on efficacy of dynamamization vs exchange nailing in treatment of delayed and nonunion femur fractures.METHODS Ultimately, 31 peer-reviewed articles with 644 exchanged nailing patients and 131 dynamization patients were identified and analyzed. The following key words were inputted in different combinations in order to search the field of publications in its entirety: 'nonunion', 'delayed union', 'ununited', 'femur fracture', 'femoral fracture', 'exchange nailing', 'dynaiz(s)ation', 'secondary nailing', 'dynamic', 'static', and 'nail revision'. The initial search yielded over 150 results, and was refined based on the inclusion criteria: Only studies reporting on humans, non-unions and delayed unions, and the usage of exchange nailing and/or dynamization as a secondary treatment after failed IM nailing. The resulting 66 articles were obtained through online journal access. The results were filtered further based on the exclusion criteria: No articles that failed to report overall union rates, differentiate between success rates of their reported techniques, or articles that analyzed less than 5 patients. RESULTS Exchange nailing lead to fracture union in 84.785% of patients compared to the 66.412% of dynamization with statistically comparable durations until union(5.193 ± 2.310 mo and 4.769 ± 1.986 mo respectively). Dynamically locking exchange nails resulted in an average union time of 5.208 ± 2.475 mo compared to 5.149 ± 2.366 mo(P = 0.8682) in statically locked exchange nails. The overall union rate of the two procedures, statically and dynamically locked exchange nailing yielded union rates of 84.259% and 82.381% respectively. Therefore, there was no significant difference between the different locking methods of exchange nailing for union rate or time to union at a significance value of P < 0.05. The analysis showed exchange nailing to be the more successful choice in the treatment of femoral non-unions in respect to its higher success rate(491/567 EN, 24/57 dynam, P < 0.0001). However, there was no significant difference between the success rates of the two procedures for delayed union fractures(25/27 EN, 45/55 dynam, P = 0.3299). Nevertheless, dynamization was more efficient in the treatment of delayed unions(at rates comparable to exchange nailing) than in the treatment of non-unions.CONCLUSION In conclusion, after examination of factors, dynamization is recommended treatment of delayed femur fractures, while exchange nailing is the treatment of choice for non-unions. | Jacob E Vaughn Ronit V Shah Tarek Samman Jacob Stirton Jiayong Liu Nabil A Ebraheim | 2018 | World Journal of Orthopedics2018，9，7： | 5 |

| 5 | Combination drug regimens for metastatic clear cell renal cell carcinoma显示文摘Renal cell carcinomas(RCC)make up about 90%of kidney cancers,of which 80%are of the clear cell subtype.About 20%of patients are already metastatic at the time of diagnosis.Initial treatment is often cytoreductive nephrectomy,but systemic therapy is required for advanced RCC.Single agent targeted therapies are moderately toxic and only somewhat effective,leading to development of immunotherapies and combination therapies.This review identifies limitations of monotherapies for metastatic renal cell carcinoma,discusses recent advances in combination therapies,and highlights therapeutic options under development.The goal behind combining various modalities of systemic therapy is to potentiate a synergistic antitumor effect.However,combining targeted therapies may cause increased toxicity.The initial attempts to create therapeutic combinations based on inhibition of the vascular endothelial growth factor or mammalian target of rapamycin pathways were largely unsuccessful in achieving a profile of increased synergy without increased toxicity.To date,five combination therapies have been approved by the U.S.Food and Drug Administration,with the most recently approved therapies being a combination of checkpoint inhibition plus targeted therapy.Several other combination therapies are under development,including some in the phase 3 stage.The new wave of combination therapies for metastatic RCC has the potential to increase response rates and improve survival outcomes while maintaining tolerable side effect profiles. | Viraj V Khetani Daniella E Portal Mansi R Shah Tina Mayer Eric A Singer | 2020 | World Journal of Clinical Oncology2020，11，8： | 2 |
