A partir d'une revue systématique de la littérature (5 études cas-témoins, 1 étude de cohorte), cette méta-analyse évalue l'association entre un indicateur caractérisant une alimentation pro-inflammatoire et le risque de cancer de la prostate

Association between Dietary Inflammatory Index and the Risk of Prostate Cancer: A Meta-Analysis

Mohseni, Reza ; Abbasi, Soheil ; Mohseni, Fatemeh ; Rahimi, Fateme ; Alizadeh, Shahab

Background: Diet is a known source of pro- and anti-inflammatory mediators, and inflammatory markers have been associated with mechanisms involved in prostate cancer initiation and progression. The Dietary Inflammatory Index (DII?) is a tool to assist researchers in determining the inflammatory potential of diet. The aim of this study was to conduct a meta-analysis to assess the association between DII and prostate cancer. Methods: EMBASE and MEDLINE were searched from inception to February [...]

A partir d'une revue systématique de la littérature (12 études), cette méta-analyse évalue l'association entre une exposition à des amines hétérocycliques d'origine alimentaire et le risque d'adénome colorectal

Dietary Heterocyclic Amine Intake and Colorectal Adenoma Risk: A Systematic Review and Meta-Analysis

Martínez Góngora, Victoria ; Matthes, Katarina L ; Rodríguez Castaño, Patricia ; Linseisen, Jakob ; Rohrmann, Sabine

Background: Heterocyclic amines (HCAs) are potent carcinogenic substances formed in meat. Due to their mutagenic activity, they may increase the risk of colorectal adenomas (CRA), which are precursors of colorectal cancer (CRC), one of the most prevalent cancers worldwide. The aim of this meta-analysis was to synthesize the knowledge about the intake of HCAs and its associations with CRA. Methods: We conducted a systematic search in PubMed and EMBASE. We used odds ratio (OR) (or relative risks, [...]

Menée aux Etats-Unis à partir de données portant sur 61 335 femmes sans antécédent de cancer après la ménopause, cette étude évalue l'association entre des changements de poids et le risque de cancer du sein (durée moyenne de suivi : 11,4 ans ; 3 061 cas)

Chlebowski, Rowan T. ; Luo, Juhua ; Anderson, Garnet L. ; Barrington, Wendy ; Reding, Kerryn ; Simon, Michael S. ; Manson, JoAnn E. ; Rohan, Thomas E. ; Wactawski-Wende, Jean ; Lane, Dorothy ; Strickler, Howard ; Mosaver-Rahmani, Yasmin ; Freudenheim, Jo L. ; Saquib, Nazmus ; Stefanick, Marcia L.

Background : Although obesity is an established risk factor for postmenopausal breast cancer, the results of weight loss and breast cancer studies are inconsistent. Therefore, we evaluated associations between weight change and breast cancer risk in postmenopausal women in the Women’s Health Initiative Observational Study. Methods : Postmenopausal women (n = 61,335) who had no prior breast cancer and a normal mammogram had body weight and height measured and body mass index (BMI) calculated at [...]

A partir d'une revue systématique de la littérature, cette étude analyse l'association entre une exposition à des oligo-éléments (arsenic, cadmium, chrome, cuivre, fer, sélénium et zinc) et le risque de cancer de la peau (mélanome, carcinome épidermoïde)

Exposure to trace elements and risk of skin cancer: A systematic review of epidemiologic studies

Matthews, Natalie H ; Fitch, Katherine ; Li, Wen-Qing ; Morris, J. Steven ; Christiani, David C. ; Qureshi, Abrar A. ; Cho, Eunyoung

Exposure to environmental trace elements has been studied in relation to many cancers. However, an association between exposure to trace elements and skin cancer remains less understood. Therefore, we conducted a systematic review of published epidemiologic literature examining the association between exposure to trace elements, and risk of melanoma and keratinocyte carcinoma in humans. We identified epidemiologic studies investigating exposure to arsenic, cadmium, chromium, copper, iron, [...]

Menée à partir de données portant sur 600 patientes afro-américaines atteintes d'un cancer de l'ovaire et sur 752 témoins, cette étude évalue l'association entre des maladies gynécologiques non malignes (endométriose, maladie inflammatoire pelvienne, kyste ovarien...) et le risque de développer une tumeur épithéliale

Benign gynecologic conditions are associated with ovarian cancer risk in African-American women: a case–control study

Park, Hyo K. ; Schildkraut, Joellen M. ; Alberg, Anthony J. ; Bandera, Elisa V. ; Barnholtz-Sloan, Jill S. ; Bondy, Melissa ; Crankshaw, Sydnee ; Funkhouser, Ellen ; Moorman, Patricia G. ; Peters, Edward S. ; Terry, Paul ; Wang, Frances ; Ruterbusch, Julie J. ; Schwartz, Ann G. ; Coté, Michele L.

Background : The association between common benign gynecologic conditions and ovarian cancer remains under-studied in African Americans. Therefore, we examine the association between self-reported history of benign gynecologic conditions and epithelial ovarian cancer risk in African-American women. Methods : Data from a large population-based, multi-center case–control study of epithelial ovarian cancer in African-American women were analyzed to estimate the association between self-reported [...]
