Physical activity and survival after breast cancer diagnosis: Meta-analysis of published studies

Ibrahim, Ezzeldin M., Al-Homaidh, Abdelaziz·2011·Medical Oncology

Abstract

Published data have shown that physical activity (PA) has a positive role on the primary prevention of breast cancer risk. However, the role of PA on breast cancer outcome has been controversial with inconsistent data. The lack of a meta-analysis that addresses that issue prompted the current report. A comprehensive literature search identified eight studies, of which two studies were excluded. The remaining six studies (12,108 patients with breast cancer) were included in this meta-analysis. Pre-diagnosis PA reduced all causes mortality by 18% but had no effect on breast cancer deaths. Post-diagnosis PA reduced breast cancer deaths by 34% (HR=0.66, 95% CI, 0.57-0.77, P<0.00001), all causes mortality by 41% (HR=0.59, 95% CI, 0.53-0.65, P<0.00001), and disease recurrence by 24% (HR=0.76, 95% CI, 0.66-0.87, P=0.00001). Breast cancer mortality was reduced by pre-diagnosis PA in women with body mass index (BMI)<25 kg/m2, while post-diagnosis PA reduced that risk among those with BMI≥25 kg/m2. On the other hand, post-diagnosis PA reduced all causes mortality regardless of the BMI. The analysis showed that post-diagnosis PA reduced breast cancer deaths (HR=0.50, 95% CI, 0.34-0.74, P=0.0005), and all causes mortality (HR=0.36, 95% CI, 0.12-1.03, P=0.06) among patients with estrogen receptor (ER)-positive tumor, while women with ER-negative disease showed no gain. The current meta-analysis provides evidence for an inverse relationship between PA and mortality in patients with breast cancer and supports the notion that appropriate PA should be embraced by breast cancer survivors.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Scientific evidence supports the safety and effectiveness of physical activity for people with cancer, indicating health benefits such as reduced anxiety, reduced depressive symptoms, reduced fatigue, improved quality of life, and improved physical function.

    “Scientific evidence supports the safety and effectiveness of physical activity, indicating—for people with cancer experience—health benefits such as reduced anxiety, reduced depressive symptoms, reduced fatigue, improved quality of life, and improved physical function [40,41,42,43].”

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.
