Anthropometric measurements and survival after a prostate cancer diagnosis
Menée au Canada auprès de 987 patients atteints d'un cancer de la prostate entre 1997 et 2000, cette étude de cohorte prospective évalue l'association entre des mesures anthropométriques après le diagnostic (taille, poids, indice de masse coporelle, tour de taille, rapport taille-hanches) et la survie
Background: Evidence regarding the role of anthropometrics in prostate cancer survival is inconsistent. We examined the associations between anthropometric measures and survival outcomes. Methods: Men diagnosed with prostate cancer (n=987) were recruited into a population-based case–control study between 1997 and 2000 then a prospective cohort study between 2000 and 2002 where anthropometric measurements (weight, height, body mass index, waist circumference, waist-hip ratio) were taken and participants were followed up to 19 years for survival outcomes. Cox proportional hazards were used to examine these associations. Results: Survival analyses suggested no clear pattern of associations between post-diagnosis anthropometric measurements and all-cause mortality, prostate-specific mortality, first recurrence/progression or new primary cancer. Conclusions: We did not find a significant trend relating anthropometrics to survival outcomes after prostate cancer diagnosis. Continued assessment of objective measurements of body composition over the life-course is warranted to determine true associations between anthropometrics and survival after prostate cancer.
