Mindfulness Meditation and Qigong for Colorectal Cancer Survivors

Colorectal cancer is one of the most common forms of cancer. Lifestyle modification and development of self-regulatory and self-care skills for maintaining psychological and physical well-being are especially important for recurrence prevention and long-term illness management. Mind-body practices are popular among cancer patients for being non-pharmacological, holistically beneficial, in addition to its feasibility for sustainable self-practice and self-care. Despite the popularity of practising qigong and mindfulness meditation among local patients, a systematic study on their effectiveness for cancer patients has yet to be conducted. Qigong and mindfulness meditation represent two distinct forms of mind-body practices: dynamic and static. With both approaches attending to the breath, Qigong relies on physical exertion to arrive at mental and psychological changes while mindfulness meditation begins at mental level but can also impact physical health. Yet current knowledge on mind-body practices tells little about these contrasting approaches. Hence, this study not only aims to provide evidence for the psychophysiological effectiveness of qigong and mindfulness meditation for colorectal cancer patients, but also elucidate how these two fundamentally contrasting approaches differ in psychophysiological outcomes, rebalancing of dysfunctional cortisol rhythm, and affect long-term practice compliance. Adopting a 3-arm randomized controlled trial design, this study will first independently study the effectiveness of Baduanjin qigong and Mindfulness meditation for Chinese colorectal cancer patients compared to controls on cancer-related symptoms and symptom distress, mental health, quality of life, biomarkers and mindfulness level. Another main objective is to examine the commonalities and differential effectiveness between a movement-based (Baduanjin qigong) and a mind-based (Mindfulness meditation) practice on the above outcomes, magnitude and pace of change, and the extended compliance throughout the 8-month study. A final objective is to examine the relationships among physical, psychological, and psychophysical variables and how these interactions between the mind and body. This study envisions advancing relationships change across the time. 189 Chinese-speaking patients with colorectal cancer will be recruited from local hospital and community organizations, then randomized into an 8-week (90-min/week) (i) Baduanjin qigong intervention, (ii) Mindfulness meditation intervention and (iii) No-intervention waitlist control. Participants will be assessed on 4 time points at (i) baseline prior randomization, (ii) mid-intervention (4th week), (iii) post-intervention (8th week) and (iv) 6 months post-intervention. The measurement of both physiological and psychological outcomes will offer a comprehensive understanding on the mental and bodily changes after each intervention and their maintenance. Results will further support the reciprocal evidence-based mind-body practices which can be easily learned, self-practiced and incorporated into patients' lifestyles.
