Abstract: Objective Immediate physical exercise has been recommended for patients in the recovery phase to improve survival and quality of life(QOL)and reduce recurrence of disease.The new NCCN Guidelines for Survivorship also highlighted the role of exercise in post-cancer health,encouraging patients to perform light physical activity following treatment.The aim of our study is to effect of Tai Chi Chuan(TCC)on serotonin and cortisol for monitoring stress and QOL in post-treatment breast cancer patients.Methods Totally85 post-treatment breast cancer patients were enrolled in this study to observe the effects of practicing TCC on recovery,as well as stress and happiness which are indicators of QOL of in patients.Peripheral blood was drawn from study subjects to analyze the levels of serotonin,cortisol and high sensitive C-reactive protein(HSCRP)at baseline,and at 3,6 and 12 months of TCC practice.Blood was drawn from healthy subjects only at baseline.A QOL questionnaire was administered to study subjects at three time points throughout the study,and once for healthy controls.The data were processed by analysis of variance of repeated measurement.Results At 3,6 and 12 months time points following regular TCC exercise,WBC,RBC,hemoglobin in blood samples showed a statistically significant difference(F=161.55,172.14,289.73;all P=0.00);the level of serotonin(biomarker for well-being),cortisol(indicator of stress)and HS-CRP(biomarker for inflammation)showed a statistical improvement(F=307.46,182.85,102.23;all P=0.00).After 3,6 and 12 months of regular TCC exercise,according to the results of QOL questionnaire,the indicators including quality of sleep,perceived hunger,fatigue,contentment,stress and social interaction presented a significant difference(F=312.98,222.64,543.90,46.05,28.10,78.92,all P<0.05),while there was no statistical difference in life dissatisfaction(F=56.61,P=0.166)Conclusions TCC physical activity for post-treatment breast cancer patients improved QOL and overall well-being,leading to improved mental,physical and psychological functioning.Regulated levels of serotonin and cortisol mediated by TCC exercises are proved to be vital for continued good health.
