摘要Background:Many cancer patients seek adjunctive therapies to biomedical cancer treatments at some point of their disease trajectory.While acupuncture is increasingly recommended by leading oncological associations,limited evidence exists concerning the evidence-informed practice and adherence to current guidelines of traditional complementary and integrative medicine(TCIM)practitioners treating cancer patients.Methods:An international online-survey assessed the demographical data,clinical practice,and sources of information used by TCIM practitioners in Austria,Germany,United States of America,Australia,and New Zealand.Results:In total,404 respondents completed the survey,of which 254(62.9％)treated cancer patients.Most practitioners were acupuncturists and herbalists(57.1％),had(16.8±9.9)years of clinical experi-ence and see a median of 2(1,4)cancer patients per week.Breast cancer(61.8％)is the most common cancer type seen in TCIM clinics.Adjunctive TCIM treatments are frequently concurrent with the patient's cancer specific treatment(39.9％),which is also reflected by the main goal of a TCIM treatment to alleviate side effects(52.4％).However,only 28.0％of the respondents are in contact with the treating oncologist.According to the respondents,pain is most effectively treated using acupuncture,while herbal medicine is best for cancer-related fatigue.TCIM practitioners mostly use certified courses(33.1％)or online data-bases(28.3％)but often believe that experts are more reliable to inform their practice(37.0％)than research publications(32.7％).Conclusion:Acupuncturists and herbalists commonly treat cancer patients.Most practitioners use TCIM as an adjunct to biomedicine as supportive care and use it largely in accordance with current oncological guidelines.
