根據歐洲癌症研究與治療組織(EORTC)乳腺癌和放射治療小組進行的一項研究,對早期乳腺癌患者進行額外劑量的放射治療可大大降低區域性復發的風險。 該研究結果將於今天在伊斯坦布林舉行的歐洲治療放射學和腫瘤學會會議上公佈。

為了確定這種加強劑量是否會幫助接受過乳房保留手術的女性,研究人員研究了 5,569 名患者,其中 95.5% 的患者已完全切除腫瘤。所有患者都接受了全乳房放射治療,然後隨機選擇接受區域性加強劑量或不接受進一步的放射治療。幾年後,對照組中有 182 名患者出現癌症復發,而加強劑量組中只有 109 名患者遭受挫折——迄今為止,風險降低了近 50%。40 歲以下的女性獲益最大,她們的復發機率降低了 54%。

研究人員將在未來幾年繼續監測患者,以觀察加強劑量是否能降低死亡率。與此同時,首席試驗協調員哈里·巴特林克斷言,研究結果應立即改變臨床實踐。他說:“這些令人印象深刻的結果意味著,加強劑量現在應被視為早期乳腺癌的標準治療方法,尤其是在年輕女性中。”

She is fascinated by human origins, which she has covered for more than 25 years. Recently she has become obsessed with birds. Her reporting has taken her to caves in France and Croatia that Neandertals once called home, to the shores of Kenya's Lake Turkana in search of the oldest stone tools in the world, to Madagascar on an expedition to unearth ancient mammals and dinosaurs, to the icy waters of Antarctica, where humpback whales feast on krill, and on a "Big Day" race around the state of Connecticut to find as many bird species as possible in 24 hours. Kate is co-author, with Donald Johanson, of Lucy's Legacy: The Quest for Human Origins. She holds a bachelor of science degree in biological anthropology and zoology from the University of Michigan.
