A Randomized, Open, Single Center Clinical Study of Dragon Boat Race Versus Family Unsupervised Training to Improve the Physical Function and Quality of Life in Breast Cancer Patients
Investigators plans to conduct a randomized, open, single center clinical study of Dragon Boat Race versus family unsupervised training to improve the physical function and quality of life in breast cancer patients to compare the effects of organized and supervised short-term dragon boat training versus unsupervised home training on body composition, physical function, and quality of life in women after breast cancer surgery. Participants will be assigned to the following intervention protocols at a 1:1 ratio:Dragon Boat Training Group (DB): Conduct 12-week dragon boat training under the guidance of professional coaches.Home-based Unsupervised Training Group (HG): Perform exercises at home independently according to instructional videos for 12 weeks.The primary outcomes are to analyze differences in body composition, physical function, and quality of life.The secondary exploratory outcomes include stratified factors such as menopausal status and surgical methods
• Female patients aged 18-75 years;
• ECOG performance status of 0-1;
• BMI between 18.0 and 30.0;
• No prior experience with dragon boat or kayaking;
• Histologically or pathologically confirmed invasive breast cancer;
• Function levels of major organs must meet the following requirements (no blood transfusion, no use of leukocyte-elevating or platelet-elevating drugs within 2 weeks before screening):
‣ Routine blood test: absolute neutrophil count (ANC) \> 1.5×10⁹/L; platelet count (PLT) \> 75×10⁹/L; hemoglobin (Hb) \> 90g/L; lymphocyte count ≥ 1.5×10⁹/L.
⁃ Blood biochemistry: total bilirubin (TBIL) \< 1.5×ULN; alanine aminotransferase (ALT) and aspartate aminotransferase (AST) \< 1.5×ULN; alkaline phosphatase \< 2.5×ULN; blood urea nitrogen/urea (BUN/UREA) and creatinine (Cr) \< 1.5×ULN.
⁃ Echocardiography: left ventricular ejection fraction (LVEF) \> 55%.
⁃ 12-lead electrocardiogram: Fridericia-corrected QT interval (QTcF) \< 470 msec. For premenopausal female patients or those not surgically sterilized: effective contraceptive methods must be used during treatment and for at least 6 months after the last dose in the study treatment.
• Voluntary participation in the study, signing of informed consent, good compliance, and willingness to cooperate with follow-up.
