This trial tested whether an intervention to reduce these risk factors in patients with Barrett esophagus, a preneoplastic condition for esophageal adenocarcinoma, could reduce biomarkers of cellular proliferation and, by inference, the risk of neoplastic progression. Eighty-seven men and women with Barrett esophagus were randomized to an intensive dietary intervention or control group. At baseline, 18 and 36 months after intervention, biopsies were obtained at 2-cm intervals throughout the length of the Barrett segment. Ki67\/DNA content flow cytometry was used to assess (a) % Ki67-positive proliferating diploid G(1) cells, (b) % total Ki67-positive proliferating cells, (c) presence of aneuploidy, and (d) presence of &gt;6% of cells in the 4N (G(2)\/tetraploid) fraction of the cell cycle. We also assessed re-epithelialization and length of the Barrett segment, reflux symptoms, and medication use. The intervention effects for energy, fat, fruits and vegetables, and weight were, respectively, -314 kcal, -12.2% energy, 1.8 servings\/d, and -4.0 kg at 18 months (all P 6% of cells in 4N were 0.5 (0.1-2.6) at 18 months and 0.75 (0.2-3.1) at 36 months. A single control participant developed aneuploidy. There were no significant effects on re-epithelialization, segment length, or reflux medication use. We conclude that substantial dietary change has no short-term effects on biomarkers of cellular proliferation in Barrett esophagus or on clinical observations of the Barrrett segment.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-49947","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Fred Hutchinson Cancer Research Center, Cancer Prevention Program, M4-B402, P.O.
