Tai Chi Improves Health-related Quality of Life in Breast Cancer Survivors
December 28, 2011 -
Breast cancer survivors experience
diminished health-related quality of life (HRQOL). A new study by University of
Rochester reports on the influence of tai chi chuan exercise (TCC) on HRQOL and
explores associations between changes in HRQOL and biomarkers.
Twenty-one breast cancer survivors were randomly assigned to TCC or
standard support therapy (SST) for 12 weeks (three times/week; 60 min/session).
Interleukin-6, interleukin-8 (IL-8), insulin-like growth factor-1 (IGF-1),
insulin-like growth factor-binding protein (IBFBP)-1, IGFBP-3, glucose, insulin,
and cortisol were measured pre- and post-intervention. Overall HRQOL and
sub-domains were assessed at pre-intervention (T1), mid-intervention (T2) and
post-intervention (T3) and biomarkers at T1 and T3.
The TCC group improved in total HRQOL, physical functioning,
physical role limitations, social functioning, and general mental health. The
SST improved in social functioning and vitality. There were relationships
between changes in IGF-1 and overall HRQOL, physical role limitation, and social
functioning. IGFBP-1 changes were associated with physical role limitations
changes. IGFBP-3 changes were associated with physical functioning changes.
Cortisol changes were associated with changes in physical role limitations and
health perceptions. Glucose changes were associated with emotional role
limitation changes. IL-8 changes were associated with emotional role limitation
TCC may improve HRQOL by regulating inflammatory responses and
other biomarkers associated with side effects from cancer and its treatments.
IMPLICATIONS FOR CANCER SURVIVORS: TCC may be an intervention capable of
improving HRQOL in breast cancer survivors.
