1976年Sporn等[1]提出“化學預防（chemoprevention）”的概念，指用化學藥物和飲食來干預腫瘤的發生過程，從而降低腫瘤的發生危險。化學預防對乳腺癌、結腸癌和前列腺癌等腫瘤的作用已有很多的研究，并取得了一些可喜的進展，但在肺癌領域進展甚微。1996年在《新英格蘭醫學雜志》上發表的b-胡蘿卜素聯合維生素A用于肺癌化學預防的報道[2]，讓人大失所望。曾經認為β-胡蘿卜素和維生素A具有“抗癌”作用，這項研究發現用β-胡蘿卜素和維生素A長期干預肺癌高危人群，干預組患肺癌的相對風險顯著高于安慰劑對照組，相對風險為1.28（95％可信區間1.04~1.57，P=0.02），肺癌發生的風險不降反升。最新的Meta分析資料也顯示β-胡蘿卜素增加吸煙者患肺癌的風險[3]。近年來肺癌的化學預防研究一直處于“低谷”之中。
