Overview

Cancer treatment with immunotherapy is often associated with symptoms such as fatigue, pain, and emotional distress, which may affect patients' daily functioning and quality of life. Additional supportive care approaches are being studied to better understand their potential role in supporting these symptoms.

The purpose of this study is to learn whether a biofield therapy, called Reiki may help to support adults with cancer who are receiving immunotherapy and currently struggling with fatigue. Reiki is a non-invasive complementary therapy delivered by a trained practitioner who places their hands lightly near the body. It is intended to promote relaxation and support general well-being. Reiki is used as a supportive practice and is not considered a medical treatment or replacement for standard care.

The secondary goal of this study is to evaluate the feasibility of delivering Reiki in this clinical setting. This includes examining recruitment, retention, adherence to study procedures, and overall participant engagement.

Lastly, the third aim is to explore participants' experiences with Reiki through guided interviews.

Participants enrolled in this study will first be asked to participate in a one-hour, one-on-one interview about their experiences with cancer treatment, their symptoms, and their thoughts about integrative care practices such as Reiki. After the interview, they will be randomly assigned to one of two groups:

Immediate Reiki Group:

If participants are assigned to this group, they will receive six weekly, in-person 30-minute Usui Reiki sessions from a Reiki master at the Susan Samueli Integrative Health Institute. Before and after each session, participants will complete questionnaires about fatigue, pain, and stress. At the first and final sessions, a small blood sample will be collected to measure inflammatory biomarkers, and Electroencephalogram (EEG) hyperscanning will be conducted to measure brain activity and connectivity between the participant and the practitioner. Four weeks after the final session, they will complete the questionnaires again, followed by a short satisfaction survey about their experience.

Waitlist Group:

If they are assigned to the waitlist group, they will first complete a 6-week observation period that includes brief weekly fatigue questionnaires and two in-person 30-minute sessions with EEG measurements at Week 1 and Week 6. This will be followed by a 4-week period with no sessions, after which they will complete questionnaires about fatigue, pain, and psychological distress. Participants will then begin the same six weekly, in-person 30-minute sessions described above. As with the Immediate Group, they will complete questionnaires before and after each session. At the first and final sessions, a small blood sample will be collected and EEG hyperscanning will be conducted. At the end of the study, participants will also complete a short satisfaction survey about their experience.

The investigators hypothesize that participants receiving Reiki will report improvements in symptoms and well-being compared to those not yet receiving Reiki, and that the intervention will be feasible to implement and acceptable to participants.
