Defining research priorities in complementary medicine in oncology.

Objectives: The high usage of complementary and alternative medicines (CAM) by cancer patients is increasing, despite limited research available to support their use. Therefore identifying research priorities that can inform the evidence base for CAM treatment is relevant for many stakeholders, including funders, researchers and consumers.

Design And Setting: Integrative medicine experts, oncologists with interest in CAM research, consumer representatives and CAM practitioners and researchers took part in a modified Delphi process conducted online over three rounds. In round 1 each participant recommended up to five CAM research priorities, which were collated and ranked in round 2 by their potential usefulness in cancer care, using a Likert scale. In round 3, participants ranked the remaining propositions by their ability to impact cancer care in Australia. The lowest ranking priorities were eliminated at the completion of each round.

Results: From the 122 propositions originally submitted by the 27 participants, the highest scoring ones included: studying interactions between biologically based CAM and conventional cancer treatments, examining CAM effects on quality of life, identifying effective communication strategies around CAM, studying the role of physical activity in symptom relief and cancer prevention and exploring the role of acupuncture in cancer care.

Conclusion: This method of research prioritisation achieved consensus of opinion among a very diverse group of stakeholders, invited to collaborate around a highly polarising topic. Through a structured interaction, the group agreed on a priority research list acceptable to all stakeholders, which can serve as a blueprint for CAM research in oncology in Australia.
