A partir d'une revue systématique de la littérature publiée jusqu'en novembre 2020 (7 études), cette méta-analyse évalue l'association entre l'index glycémique, la charge glycémique ou l'apport quotidien en glucides et le risque de carcinome hépatocellulaire

Background: Glycemic index (GI), glycemic load (GL) and daily carbohydrates intake have been associated with a variety of cancers, but their implications in hepatocellular carcinoma (HCC) remain controversial. The purpose of our study is to investigate the association of GI, GL and daily carbohydrates intake with the risk of HCC. Methods: Systematic searches were conducted in PubMed, Embase and Web of Science until November 2020. According to the degree of heterogeneity, random effect model or [...]

Menée à partir des données d'une étude portant sur 34 421 Afro-américaines, cette étude analyse l'association entre des perturbations du rythme circadien (travail de nuit, chronotype, fuseau horaire...) et le risque de cancer colorectal (204 cas)

Circadian disruption and colorectal cancer incidence in Black women

Barber, Lauren E. ; VoPham, Trang ; White, Laura F. ; Roy, Hemant K. ; Palmer, Julie R. ; Bertrand, Kimberly A.

Background: Animal and experimental studies suggest circadian disruption increases colorectal cancer risk, but evidence in humans is limited. We examined night shift work, chronotype, and residential position within a time zone, proxies for circadian disruption, in relation to colorectal cancer risk. Methods: Participants in the Black Women’s Health Study, a prospective cohort of 59,000 Black American women established in 1995, reported history of night shift work and chronotype on follow-up [...]

Menée à partir des données de 8 études portant au total sur 3 124 témoins et 811 patientes atteintes d'un cancer de l'endomètre, cette étude identifie les facteurs de risque associés à la maladie chez les femmes afro-américaines

Risk factors for endometrial cancer in Black women

Sponholtz, Todd R. ; Palmer, Julie R. ; Rosenberg, Lynn ; Chen, Chu ; Chen, Yu ; Clarke, Megan A. ; Clendenen, Tess ; Du, Mengmeng ; Johnson, Lisa ; Liao, Linda M. ; Michels, Kara A. ; O’Connell, Kelli ; Olson, Sara H. ; Petruzella, Stacey ; Rebbeck, Timothy R. ; Setiawan, Veronica Wendy ; Trabert, Britton ; Weiss, Noel S. ; Wentzensen, Nicholas ; Wilkens, Lynne ; Wise, Lauren A.

Purpose: The incidence of endometrial cancer (EC) has been increasing faster among Black women than among other racial/ethnic groups in the United States. Although the mortality rate is nearly twice as high among Black than White women, there is a paucity of literature on risk factors for EC among Black women, particularly regarding menopausal hormone use and severe obesity. Methods: We pooled questionnaire data on 811 EC cases and 3,124 controls from eight studies with data on self-identified [...]

Menée à l'aide de données 2000-2018 des registres américains des cancers portant sur 56 784 patientes atteintes d'un cancer du sein et ayant subi une mastectomie (âge médian : 50-54 ans ; durée médiane de suivi : 81 mois), cette étude analyse le risque de lymphome anaplasique à grandes cellules associé à une reconstruction par implant mammaire

Risk of Anaplastic Large Cell Lymphoma Following Postmastectomy Implant Reconstruction in Women With Breast Cancer and Ductal Carcinoma in Situ

Kinslow, Connor J. ; DeStephano, David M. ; Rohde, Christine H. ; Kachnic, Lisa A. ; Cheng, Simon K. ; Neugut, Alfred I. ; Horowitz, David P.

Approximately 291 000 and 51 000 cases of breast cancer and ductal carcinoma in situ, respectively, are diagnosed in the US annually, the majority of whom undergo local curative surgery, including mastectomy with implant-based reconstruction. National and regulatory guidelines recommend that patients eligible for reconstruction be counseled on the association of breast implants with subsequent anaplastic large cell lymphoma (ALCL) as part of routine informed consent. Several series of patients [...]
