Interdisciplinary Integrative Oncology Group-Based Program: Evaluation of Long-Term Effects on Resilience and Use of Complementary and Alternative Medicine in Patients With Cancer

Background: Cancer often causes reduced resilience, quality of life (QoL) and poorer overall well-being. To mitigate these problems, complementary and alternative medicine (CAM) is widely used among patients with cancer. This study aimed to evaluate the long-term effects of an interdisciplinary integrative oncology group-based program (IO-GP) on the resilience and use of CAM in patients with cancer. Methods: This was a prospective, observational, single-center study. Resilience (RS-13), CAM usage (I-CAM-G), QoL (SF-12) and health-related lifestyle factor (nutrition, smoking, alcohol consumption and physical exercise) data were collected for 70 patients who participated in a 10-week IO-GP between January 2019 and June 2022 due to cancer. The IO-GP is offered at the setting of a university hospital and is open to adult patients with cancer. It contains elements from mind-body medicine and positive psychology, as well as recommendations on healthy diet, exercise and CAM approaches. Patients who completed the IO-GP at least 12 months prior (1-4.5 years ago) were included in this study. Statistical analysis included descriptive analysis and parametric and nonparametric tests to identify significant differences ( P 36 months”) showed no statistically significant interaction with changes in resilience ( P = .226, F = 1.544). The most frequently used CAM modalities within the past 12 months were vitamins/minerals (85.7%), relaxation techniques (54.3%), herbs and plant medicine (41.1%), yoga (41.4%) and meditation (41.4%). The IO-GP was the most common source informing study participants about relaxation techniques (n = 24, 64.9%), meditation (n = 21, 72.4%) and taking vitamin D (n = 16, 40.0%). Significantly greater levels of resilience were found in those practicing meditation ( P = .010, d = −.642) or visualization ( P = .003, d = −.805) compared to non-practitioners. Conclusion: IO-GPs have the potential to empower patients with cancer to continue using CAM practices—especially from mind-body medicine—even 1 to 4.5 years after completing the program. Additionally, resilience levels increased. These findings provide notable insight into the long-term effects of integrative oncology interventions on resilience and the use of CAM, especially in patients with breast cancer.
