| 1 | Pancreatic cancer: A review of clinical diagnosis, epidemiology, treatment and outcomes显示文摘This review aims to outline the most up-to-date knowledge of pancreatic adenocarcinoma risk, diagnostics, treatment and outcomes, while identifying gaps that aim to stimulate further research in this understudied malignancy. Pancreatic adenocarcinoma is a lethal condition with a rising incidence, predicted to become the second leading cause of cancer death in some regions. It often presents at an advanced stage, which contributes to poor five-year survival rates of 2%-9%, ranking firmly last amongst all cancer sites in terms of prognostic outcomes for patients. Better understanding of the risk factors and symptoms associated with this disease is essential to inform both health professionals and the general population of potential preventive and/or early detection measures. The identification of high-risk patients who could benefit from screening to detect pre-malignant conditions such as pancreatic intraepithelial neoplasia, intraductal papillary mucinous neoplasms and mucinous cystic neoplasms is urgently required, however an acceptable screening test has yet to be identified. The management of pancreatic adenocarcinoma is evolving, with the introduction of new surgical techniques and medical therapies such as laparoscopic techniques and neo-adjuvant chemoradiotherapy, however this has only led to modest improvements in outcomes. The identification of novel biomarkers is desirable to move towards a precision medicine era, where pancreatic cancer therapy can be tailored to the individual patient, while unnecessary treatments that have negative consequences on quality of life could be prevented for others. Research efforts must also focus on the development of new agents and delivery systems. Overall, considerable progress is required to reduce the burden associated with pancreatic cancer. Recent, renewed efforts to fund large consortia and research into pancreatic adenocarcinoma are welcomed, but further streams will be necessary to facilitate the momentum needed to bring breakthroughs seen for other cancer sites. | Andrew McGuigan Paul Kelly Richard C Turkington Claire Jones Helen G Coleman R Stephen McCain | 2018 | World Journal of Gastroenterology2018，24，43： | 140 |
| 2 | Intentional ingestions of foreign objects among prisoners: A review显示文摘The intentional ingestion of foreign objects(IIFO) is described more commonly in prison populations than in the general population, with an estimated annual incidence of 1 in 1900 inmates in our state correctional facilities. Incidents often involve ingestion of small metal objects(e.g., paperclips, razor blades) or other commonly available items like pens or eating utensils. Despite ingestion of relatively sharp objects, most episodes can be clinically managed with either observation or endoscopy. Surgery should be reserved for those with signs or symptoms of gastrointestinal perforation or obstruction. For those with a history of IIFO, efforts should focus on prevention of recurrenceas subsequent episodes are associated with higher morbidity, significant healthcare and security costs. The pattern of IIFO is often repetitive, with escalation both in frequency of ingestions and in number of items ingested. Little is known about successful prevention strategies, but efforts to monitor patients and provide psychiatric care are potential best-practice strategies. This article aims to provide state-of-the art review on the topic, followed by a set of basic recommendations. | David C Evans Thomas R Wojda Christian D Jones Andrew J Otey Stanislaw P Stawicki | 2015 | World Journal of Gastrointestinal Endoscopy2015，7，3： | 10 |
| 3 | Primary squamous cell carcinoma of the rectum: An update and implications for treatment显示文摘AIM: To provide an update on the aetiology, pathogenesis, diagnosis, staging and management of rectal squamous cell carcinoma(SCC).METHODS: A systematic review was conducted according to the preferred reporting items for Systematic Reviews and Meta-Analyses guidelines. A comprehensive search of Ovid MEDLINE was performed with the reference list of selected articles reviewed to ensure all relevant publications were captured. The search strategy was limited to the English language, spanning from 1946 to 2015. A qualitative analysis was undertaken examining patient demographics, clinical presentation, diagnosis, staging, treatment and outcome. The quantitaive analysis was limited to data extracted on treatment and outcomes including radiological, clinical and pathological complete response where available. The narrative and quantitative review were synthesised in concert.RESULTS: The search identified 487 articles in total with 79 included in the qualitative review. The quantitative analysis involved 63 articles, consisting of 43 case reports and 20 case series with a total of 142 individual cases. The underlying pathogenesis of rectal SCC while unclear, continues to be defined, with increasing evidence of a metaplasia-dysplasia-carcinoma sequence and a possible role for human papilloma virus in this progression. The presentation is similar to rectal adenocarcinoma, with a diagnosis confirmed by endoscopic biopsy. Many presumed rectal SCC's are in fact an extension of an anal SCC, and cytokeratin markers are a useful adjunct in this distinction. Staging is most accurately reflected by the tumour-nodemetastasis classification for rectal adenocarcinoma. It involves examining locoregional disease by way of magnetic resonance imaging and/or endorectal ultrasound, with systemic spread excluded by way of computed tomography. Positron emission tomography is integral in the workup to exclude an external siteof primary SCC with metastasis to the rectum. While the optimal treatment remains as yet undefined, recent studies have demonstrated a global shift away from surgery towards definitive chemoradiotherapy as primary treatment. Pooled overall survival was calculated to be 86% in patients managed with chemoradiation compared with 48% for those treated traditionally with surgery. Furthermore, local recurrence and metastatic rates were 25% vs 10% and 30% vs 13% for the chemoradiation vs conventional treatment cohorts.CONCLUSION: The changing paradigm in the treatment of rectal SCC holds great promise for improved outcomes in this rare disease. | Glen R Guerra Cherng H Kong Satish K Warrier Andrew C Lynch Alexander G Heriot Samuel Y Ngan | 2016 | World Journal of Gastrointestinal Surgery2016，8，3： | 5 |
| 4 | Refining pathological evaluation of neoadjuvant therapy for adenocarcinoma of the esophagus显示文摘AIM:To assess tumour regression grade(TRG)and lymph node downstaging to help define patients who benefit from neoadjuvant chemotherapy.METHODS:Two hundred and eighteen consecutive patients with adenocarcinoma of the esophagus or gastro-esophageal junction treated with surgery alone or neoadjuvant chemotherapy and surgery between 2005and 2011 at a single institution were reviewed.Triplet neoadjuvant chemotherapy consisting of platinum,fluoropyrimidine and anthracycline was considered for operable patients(World Health Organization performance status≤2)with clinical stage T2-4 N0-1.Response to neoadjuvant chemotherapy(NAC)was assessed using TRG,as described by Mandard et al.In addition lymph node downstaging was also assessed.Lymph node downstaging was defined by cN1 at diagnosis:assessed radiologically(computed tomography,positron emission tomography,endoscopic ultrasonography),then pathologically recorded as N0 after surgery;ypN0 if NAC given prior to surgery,or pN0if surgery alone.Patients were followed up for 5 years post surgery.Recurrence was defined radiologically,with or without pathological confirmation.An association was examined between t TRG and lymph node downstaging with disease free survival(DFS)and a comprehensive range of clinicopathological characteristics.RESULTS:Two hundred and eighteen patients underwent esophageal resection during the study interval with a mean follow up of 3 years(median follow up:2.552,95%CI:2.022-3.081).There was a 1.8%(n=4)inpatient mortality rate.One hundred and thirty-six(62.4%)patients received NAC,with 74.3%(n=101)of patients demonstrating some signs of pathological tumour regression(TRG 1-4)and 5.9%(n=8)having a complete pathological response.Forty four point one percent(n=60)had downstaging of their nodal disease(cN1 to ypN0),compared to only 15.9%(n=13)that underwent surgery alone(pre-operatively overstaged:cN1 to pN0),(P<0.0001).Response to NAC was associated with significantly increased DFS(mean DFS;TRG 1-2:5.1years,95%CI:4.6-5.6 vs TRG 3-5:2.8 years,95%CI:2.2-3.3,P<0.0001).Nodal down-staging conferred a significant DFS advantage for those patients with a poor primary tumour response to NAC(median DFS;TRG 3-5 and nodal down-staging:5.533 years,95%CI:3.558-7.531 vs TRG 3-5 and no nodal down-staging:1.114 years,95%CI:0.961-1.267,P<0.0001).CONCLUSION:Response to NAC in the primary tumour and in the lymph nodes are both independently associated with improved DFS. | Fergus Noble Luke Nolan Adrian C Bateman James P Byrne Jamie J Kelly Ian S Bailey Donna M Sharland Charlotte N Rees Timothy J Iveson Tim J Underwood Andrew R Bateman | 2013 | World Journal of Gastroenterology2013，19，48： | 4 |
| 5 | A new Early Cretaceous dinosaur track assemblage and the first definite non-avian theropod swim trackway from China显示文摘The trackway of a swimming theropod (ichnogenus Characichnos) is reported from the Lower Cretaceous Feitianshan Formation of Sichuan, China. These swim tracks help confirm that non-avian theropods were capable of forging moderately deep bodies of water. The trackway occurs on the same surface as a typical walking trackway of a sauropod (ichnogenus Brontopodus). Both occurrences are the first reported from the Cretaceous of Sichuan, and the swim tracks are the first well-preserved example of a Characichnos trackway from China. Additionally, a theropod walking trackway and several ornithopod walking trackways (similar to the ichnogenus Caririchnium) occur in the same horizon. The ornithopod trackways show a parallel orientation, suggesting gregarious behavior of the trackmakers, which may have been iguanodontiforms and/or hadrosauriforms. The co-occurrence of theropod swim tracks and theropod walking tracks suggests a fluctuation of water depth within a distinct time span. | XING LiDa LOCKLEY Martin G ZHANG JianPing MILNER Andrew R C KLEIN Hendrik LI DaQing PERSONS IV W Scott EBI JieFang | 2013 | Chinese Science Bulletin2013，58，19： | 3 |
