| 1 | Molecular detection of pancreatic neoplasia: Current status and future promise显示文摘Pancreatic cancer is usually diagnosed at an advanced stage and curative resection is feasible in only a small minority of patients at the time of diagnosis. Diagnosis at an early stage is unequivocally associated with better long-term survival. Several candidate molecular markers for early detection are currently under investigation in different phases of discovery and validation. Recent advances in the technology for whole genome,methylome,ribonucleome,and proteome interrogation has enabled rapid advancements in the field of biomarker discovery. In this review we discuss the current status of molecular markers for detection of pancreatic cancer in blood,pancreatic cyst fluid,pancreatic juice and stool and briefly highlight some promising preliminary results of new approaches that have the potential of advancing this field in the near future. | Shounak Majumder Suresh T Chari David A Ahlquist | 2015 | World Journal of Gastroenterology2015，21，40： | 3 |
| 5 | Patient perceptions of stool DNA testing for pan-digestive cancer screening:A survey questionnaire显示文摘AIM:To explore patient interest in a potential multiorgan stool-DNA test(MUST)for pan-digestive cancer screening.METHODS:A questionnaire was designed and mailed to 1200 randomly-selected patients from the Mayo Clinic registry.The 29-item survey questionnaire included items related to demographics,knowledge of digestive cancers,personal and family history of cancer,personal concern of cancer,colorectal cancer(CRC)screening behavior,interest in MUST,importance of test features in a cancer screening tool,and comparison of MUST with available CRC screening tests.All responses were summarized descriptively.χ2 and Rank Sum Test were used for categorical and continuous variables,respectively.RESULTS:Completed surveys were returned by 434(29%aged 50-59,37%60-69,34%70-79,52%women).Most participants(98%)responded they would use MUST.In order of importance,respondents rated multicancer detection,absence of bowel preparation,safety and noninvasiveness as most attractive characteristics.For CRC screening,MUST was preferred over colorectal-only stool-DNA testing(53%),occult blood testing(75%),colonoscopy(84%),sigmoidoscopy(91%),and barium enema(95%),P<0.0001 for each.Among those not previously screened,most(96%)indicated they would use MUST if available.Respondents were confident in their ability to follow instructions to perform MUST(98%).Only 9%of respondents indicated that fear of finding cancer was a concern with MUST,and only 3%indicated unpleasantness of stool sampling as a potential barrier.CONCLUSION:Patients are receptive to the concept of MUST,preferred MUST over conventional CRC screening modalities and valued its potential feature of multi-cancer detection. | Dennis Yang Shauna L Hillman Ann M Harris Pamela S Sinicrope Mary E Devens David A Ahlquist | 2014 | World Journal of Gastroenterology2014，20，17： | 1 |
