Supportive Intervention Programs Study

OBJECTIVES:

I. To establish the feasibility of implementing a YST among patients undergoing chemotherapy. This includes the feasibility of implementing yoga in a treatment setting, and patient recruitment, adherence, and retention.

II. To obtain preliminary data on the efficacy of a YST for reducing fatigue among patients undergoing chemotherapy.

III. To obtain exploratory data on the impact of a YST on other treatment-related symptoms (e.g., pain, distress, nausea) and QOL.

IV. To obtain exploratory data on the impact of a YST on potential psychological (self-efficacy for coping with cancer, response expectancies for symptoms) and physiological (interleukin \[IL\]-6 \[IL-6\], IL-1 Receptor Antagonist \[IL-1Ra\], tumor necrosis factor- alpha \[TNF-a\], soluble TNF receptor I \[sTNFRI\], C-reactive protein \[CRP\]) mediators that may explain the impact of the YST on fatigue.

OUTLINE: Patients (n=20) are randomized to 1 of 2 treatment arms.

ARM I: Patients participate in three 15-minute YST sessions, comprising awareness meditation practice, movement practice, and breathing practice and relaxation. Patients also receive a compact disc (CD) recording of a 15-minute YST session and are instructed to practice the YST at home 4 times weekly.

ARM II: Patients participate in three 15-minute CE sessions, comprising empathic attention with an interventionist who allows patients to direct the flow of conversation and provides supportive comments according to standardized procedures. Patients also receive CDs with recorded information related to coping with colorectal cancer similar in length to the suggested practice time in Arm I.

The interventions (Week 2, Week 4, Week 6) and assessments (Week 0, Week 4, Week 8) are implemented during visits for chemotherapy (every two weeks).

• Yoga therapy (Procedure): receive YST
• questionnaire administration (Other): Ancillary studies
• quality-of-life assessment (Procedure): Ancillary studies
• laboratory biomarker analysis (Other): Correlative studies
• assessment of therapy complications (Other): Ancillary studies
• management of therapy complications (Procedure), also known as complications of therapy, management of: Receive YST or CE
• educational intervention (Other): Receive CE

Primary outcomes

• Feasibility of implementing a YST among patients undergoing chemotherapy (participating rate, adherence, and retention) [Up to 8 weeks]: The proportion of participants who participated in all study sessions and those who completed all assessments will be computed and compared by demographic characteristics and intervention group. The investigators will model the relationship between adherence and baseline scores of the measures, as well as change in scores.

Secondary outcomes

• Preliminary efficacy of YST, in terms of reducing fatigue [At week 8]: Measured by the Functional Assessment of Cancer Therapy - Fatigue (FACT-F) subscale. Assessed using analysis of covariance (ANCOVA) models, accounting for possible confounding variables (e.g., medication use) from baseline to post intervention.
• Treatment related symptoms and QOL [At week 8]: The Functional Assessment of Cancer Therapy- Colorectal (FACT-C; 37) will be used to evaluate overall QOL (physical, social, emotional, and functional well-being) and colorectal cancer specific symptoms (e.g., cramps in stomach, control of bowels). Assessed using ANCOVA.
• Mediating variables (self efficacy, response expectancies, inflammatory biomarkers) intervention effect on fatigue, treatment-related symptoms, and QOL [Up to 8 weeks]: Assessed using a simultaneous model of the mediators and the intervention effect in the ANCOVA model.
