Background and objective: Up to 60% of all oncological patients use me
thods of alternative medicine in the course of their illness. In earli
er blinded studies demographic characteristics and the patients' motiv
es of using alternative medicine had been recorded, but a correlation
with individual illnesses had not been possible. Patients and methods:
142 patients of a oncological outpatient clinic gave their experience
with alternative medicine in interviews and non-blinded questionnaire
s, 103 of them (72.5%; 46 men and 57 women; median age 58 years, range
18-91 years) returning questionnaires that could be evaluated. Result
s: 46 patients stated that they had used alternative medicine. There w
as no difference between users and nonusers regarding sex, age, profes
sion, education, family status or religion. 58% of all patients with a
dvanced disease used alternative medicine, compared with only 31% with
partial remission or stable disease and 41% in complete remission (P=
0.042). Vitamins and mistletoe preparations were the most commonly use
d substances (50 and 45 %, respectively). The predominant purpose was
to stimulate the immune system (77 %) and strengthen general physical
capacity (64.5 %). As main stimulus for using alternative medicine the
patients came from their family doctor (56%), followed by family and
friends (41 %). Alternative medicine was used largely as complementary
and not an alternative to conventional medicine. Health insurances me
t all or of some of the costs of alternative treatment in 59% of patie
nts. Conclusion: A large number of patients treated with conventional
oncological regimens also use alternative medicine, most of them becau
se of a polypragmatic attitude to tumor treatment. Family doctors and
health insurance companies are playing a more important role than had
hitherto been assumed in spreading the use of treatment options withou
t providing scientifically based evidence of their efficacy.
