  Purpose
A Finnish Breast Cancer Group Study (BREX 01-2004). A multicenter phase III open randomised trial of the efficacy of exercise in the prevention of long-term adverse effects of adjuvant treatments and breast cancer recurrences in women with primary breast cancer. The aim of the study is to investigate whether regular exercise training could reduce the long-term side effects of adjuvant treatments of primary breast cancer and improve quality of life and well being.

Condition Intervention Phase
Prevent Osteoporosis and Osteoporotic Fractures Improve Quality of Life Improve Weight Control, and Muscular and Cardiovascular Fitness Help the Patients to Return to Working Life Reduce the Risk of Breast Cancer Recurrence Prevent Other Diseases and Reduce All-Cause Mortality in Patients With Primary Breast Cancer. Other: supervised training Phase 3

Study Type: Interventional

Primary Outcome Measures:
  • The aim of the study is to investigate whether regular exercise after adjuvant treatments of breast cancer could prevent osteoporosis and improve quality of life. [ Time Frame: 1-10 years ]

Secondary Outcome Measures:
  • Fitness and weight control, number of falls and fractures, breast cancer recurrence. [ Time Frame: 1-10 years ]

Enrollment: 573
Study Start Date: September 2005
Study Completion Date: September 2007
Primary Completion Date: September 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
A
Supervised training is organised for the exercise group once a week in groups of 10 to 15 subjects. The training is guided by an experienced physical therapist.
Other: supervised training
Design: supervised training is organised for the exercise group once a week in groups of 10 to 15 subjects. The training is guided by an experienced physical therapist.Content: The supervised training of the exercise group consists of two different classes alternating at four week periods; step aerobics class and circuit training class. The 60-minute aerobics and circuit training classes also include warming-up and cooling-down periods both lasting 10-15 minutes.
No Intervention: B

Detailed Description:
A multicenter phase III open randomised trial of the efficacy of exercise in the prevention of long-term adverse effects of adjuvant treatments and breast cancer recurrences in women with primary breast cancer. The aim of the study is to investigate whether regular exercise training could reduce the long-term side effects of adjuvant treatments of primary breast cancer and improve quality of life and well being. Large controlled prospective studies are needed to confirm the preliminary findings of exercises benefits in cancer patients, and to investigate the type, the frequency, intensity and tolerability of exercise training in cancer patients, before any clinical recommendations can be given. Prevention of osteoporosis, improvement of weight control, and muscular and cardiovascular fitness is been waited. The second aim of the study is to investigate, whether regular exercise training reduces the risk of breast cancer recurrence, prevents other diseases and reduce all-cause mortality and is cost effective in women with primary breast cancer.
