Short-term\/acute and long-term\/late side effects also were measured.<\/p>\n\n\n\n<p>At five years, survival rates for men who received brachytherapy alone were comparable to those who underwent more aggressive radiation treatment.<\/p>\n\n\n\n<p>The rate at five years post-treatment was 85% for EBT+B patients and 86% for B patients.<\/p>\n\n\n\n<p>Although rates were comparable between treatment groups, differences emerged in the rates of more serious side effects.<\/p>\n\n\n\n<p>Overall toxicity levels were similar across groups only for acute side effects (i.e., those that occur closely following treatment), with eight percent of patients in each cohort reporting acute grade 3+ side effects.<\/p>\n\n\n\n<p>Late severe toxicities were more common for EBT+B patients (12 percent) than for B patients (7 percent), as were severe GU side effects GU (7 vs. 3 percent) and severe GI toxicities (3 vs. 2 percent).<\/p>\n\n\n\n<p>\u201cThese findings suggest that many men with intermediate risk prostate cancer can be well managed with seed implant alone and do not require the addition of external beam radiation,\u201d said Bradley Prestidge, MD, lead author of the study.<\/p>\n\n\n\n<p>\u201cContrary to expectations, the more aggressive, combined treatment did not result in superior cancer control rates at five years follow-up, indicating that men can achieve a similar survival benefit with fewer late side effects through brachytherapy alone.\u201d<\/p>\n<\/div><\/div><\/div>","protected":false},"excerpt":{"rendered":"","protected":false},"author":10,"featured_media":2650,"comment_status":"open","ping_status":"open","sticky":false,"template":"template-old-blog.php","format":"standard","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[9],"tags":[],"class_list":["post-2649","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-healthcare-professionals"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.4 -
