This study was carried out with 389 subjects consisting of 160 breast cancer patients and 229 control subjects from June 1994 to July 1995. The serum concentrations of alpha-tocopherol, carotenoids and retinol were measured simultaneously by a reverse phase, gradient HPLC system. Average serum concentrations of alpha-tocopherol, beta-carotene and retinol were 7.63 +\/- 0.42 &micro;g\/ml, 40.5 +\/- 2.05 &micro;g\/dl, and 49.0 +\/- 4.10 &micro;g\/dl for cases and 11.0 +\/- 0.73 &micro;g\/ml, 48.3 +\/- 1.59 &micro;g\/dl and 64.6 +\/- 1.95 &micro;g\/dl for controls, respectively. Serum levels of alpha-tocopherol, beta -carotene, cryptoxanthin, lutein + zeaxanthin, lycopene and retinol of breast cancer patients were significantly lower than those of controls. Odds ratios (ORs) adjusted for age, body mass index, smoking habit and alcohol drinking revealed a significant gradient of decreasing risk of breast cancer with increasing serum antioxidant vitamins. There were significant interactions between menopausal status and serum levels of antioxidant vitamins. The adjusted odds ratios for highest quintile compared with lowest quintile were 0.41 (95% CI, 0.18, 0.93) for alpha-tocopherol, 0.33 (95% CI, 0.15, 0.73) for beta-carotene, 0.13 (95% CI, 0.06, 0.31) for zeaxanthin + lutein in premenopausal women; 0.13 (95% CI, 0.03, 0.66) for alpha-tocopherol, 0.28 (95% CI, 0.07, 1.12) for beta-carotene, 0.12 (95% CI, 0.03, 0.58) for zeaxanthin + lutein in postmenopausal women. This results support inverse association between serum antioxidant vitamins and the risk of breast cancer in Korea and indicate that antioxidant vitamins may protect against breast cancer.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-56687","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"\"LEE-KIM YC,YONSEI UNIV,COLL HUMAN ECOL DEPT FOOD & NUTR SEODAEMUN GU;134 SINCHON DONG; SEOUL 120749, SOUTH KOREA.ycleekim@yonsei.ac.kr\"","annee":"2001","mois":"6","numero":"21:6","page":"797-809","auteurs":[{"ID":56685,"post_author":"0","post_date":"2018-12-04 07:27:14","post_date_gmt":"2018-12-04 06:27:14","post_content":"","post_title":"Ahn","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"ahn-4","to_ping":"","pinged":"","post_modified":"2018-12-04 07:27:14","post_modified_gmt":"2018-12-04 06:27:14","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/ahn-4\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":9029,"post_author":"0","post_date":"2018-12-03 18:06:34","post_date_gmt":"2018-12-03 17:06:34","post_content":"","post_title":"Mi Kyung Kim","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"mi-kyung-kim","to_ping":"","pinged":"","post_modified":"2018-12-03 18:06:34","post_modified_gmt":"2018-12-03 17:06:34","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/mi-kyung-kim\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":56686,"post_author":"0","post_date":"2018-12-04 07:27:15","post_date_gmt":"2018-12-04 06:27:15","post_content":"","post_title":"Lee-kim","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"lee-kim","to_ping":"","pinged":"","post_modified":"2018-12-04 07:27:15","post_modified_gmt":"2018-12-04 06:27:15","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/lee-kim\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":43958,"post_author":"0","post_date":"2018-12-04 03:15:19","post_date_gmt":"2018-12-04 02:15:19","post_content":"","post_title":"NUTRITION RESEARCH","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"nutrition-research","to_ping":"","pinged":"","post_modified":"2018-12-04 03:15:19","post_modified_gmt":"2018-12-04 02:15:19","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/nutrition-research\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
