The investigators aim to investigate the validity of their previous results in a randomized
prospective, placebo-controlled, double-blind, multicenter controlled evaluation of
questionnaires in patients with advanced malignant tumors. The investigators plan to compare
the treatment outcome (quality of life and survival) in tumor patients, receiving standard or
"add-on" homeopathic treatment.
The null hypothesis is that "add-on" homeopathic treatment does not create a benefit for
cancer patients. In addition the investigators evaluate survival time.
