Abstract

Increasing evidence suggested obesity, measured by body mass index (BMI), was associated with prostate cancer–specific mortality, and its impact on biochemical recurrence was also inconclusive. We systematically searched MEDLINE, EMBASE, and bibliographies of retrieved studies up to January 5, 2010. We used random-effects meta-analysis to assess the relative risks (RR) of prostate cancer-specific mortality and biochemical recurrence associated with a 5 kg/m2 increase in BMI. Among the six population-based cohort studies in 1,263,483 initially cancer-free men, 6,817 prostate cancer deaths occurred; a 5 kg/m2 increase in BMI was associated with 15% (RR: 1.15, 95% confidence interval (CI): 1.06–1.25, P < 0.01) higher risk of dying of prostate cancer. In the six postdiagnosis survival studies on 18,203 patients with 932 prostate cancer deaths, a 5 kg/m2 increase in BMI was associated with 20% higher prostate cancer–specific mortality (RR: 1.20, 95% CI: 0.99–1.46, P = 0.06). In the sixteen studies which followed 26,479 prostate cancer patients after primary treatment, a 5 kg/m2 increase in BMI was significantly associated with 21% increased risk of biochemical recurrence (RR: 1.21, 95% CI: 1.11–1.31 P < 0.01). Elevated BMI is associated with risk of prostate cancer–specific mortality in prospective cohort studies and biochemical recurrence in prostate cancer patients. Its association with prostate cancer–specific mortality in diagnosed patients needs to be further evaluated. Cancer Prev Res; 4(4); 486–501. ©2011 AACR.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
