Mistletoe extract (Iscador®) in cancer patients undergoing chemotherapy for prostate and bladder tumors: A prospective observational study

Objective

While mistletoe (a semi-parasitic evergreen plant) extract is commonly used as a complementary therapy in Europe, the evidence for its efficacy against the toxicity of chemotherapy is mixed. Our study aimed to evaluate the impact of mistletoe extract as a complementary therapy on the health-related quality of life (HRQoL) and hematological toxicities in patients with metastatic prostate and bladder cancers undergoing chemotherapy.
