| 8 | Is proliferative colonic disease presentation changing?显示文摘AIM:To compare the site,age and gender of cases of colorectal cancer(CRC) and polyps in a single referral center in Rome,Italy,during two periods.METHODS:CRC data were collected from surgery/pathology registers,and polyp data from colonoscopy reports.Patients who met the criteria for familial adenomatous polyposis,hereditary non-polyposis colorectal cancer syndrome or inflammatory bowel disease were excluded from the study.Overlap of patients between the two groups(cancers and polyps) was carefully avoided.Theχ 2 statistical test and a regression analysis were performed.RESULTS:Data from a total of 768 patients(352 and 416 patients,respectively,in periods A and B) who underwent surgery for cancer were collected.During the same time periods,a total of 1693 polyps were analyzed from 978 patients with complete colonoscopies(428 polyps from 273 patients during period A and 1265 polyps from 705 patients during period B).A proximal shift in cancer occurred during the latter years for both sexes,but particularly in males.Proximal cancer increased > 3-fold in period B compared to period A in males [odds ratio(OR) 3.31,95%CI:2.00-5.47;P < 0.0001).A similar proximal shift was observed for polyps,particularly in males(OR 1.87,95%CI:1.23-2.87;P < 0.0038),but also in females(OR 1.62,95%CI:0.96-2.73;P < 0.07).CONCLUSION:The prevalence of proximal proliferative colonic lesions seems to have increased over the last decade,particularly in males. | Vito D Corleto Cristiano Pagnini Maria Sofia Cattaruzza Ermira Zykaj Emilio Di Giulio Giovanna Margagnoni Emanuela Pilozzi Giancarlo D'Ambra Antonietta Lamazza Enrico Fiori Mario Ferri Luigi Masoni Vincenzo Ziparo Bruno Annibale Gianfranco Delle Fave | 2012 | World Journal of Gastroenterology2012，18，45： | 0 |
