Abstract
Chemotherapy-induced side effects include an impaired nutritional status and reduced quality of life in patients. The contribution of propolis, as a co-adjuvant nutritional supplement in cancer treatment, is suggested due to its functional characteristics and biological activities such as antitumoral activity, DNA protection, free radicals scavenging, and immune stimulation; however, clinical trials to support these effects in cancer patients are necessary. This is a randomized, double-blind, placebo-controlled clinical trial to assess the effect of propolis vs. placebo on the nutritional status and quality of life in patients diagnosed with breast cancer who are receiving chemotherapy (No. IRCT2016062828679N1). A total of 60 patients from the Oncology Clinic at Tohid Hospital, Sanandaj, Iran were randomized to receive propolis (250 mg/two times per day for three months) or a placebo. After three months of intervention, energy intake of patients who received propolis increased significantly compared to placebo group (p = 0.000). The quality of life also showed significant improvements in patients receiving propolis, particularly with regards to emotional functioning (p = 0.03), global QoL functioning (p = 0.04), and financial difficulties (p = 0.01) compared to the control group. Propolis is suggested an adequate and safe therapeutic option to improve the nutritional status and quality of life in patients diagnosed with breast cancer receiving chemotherapy. However, more trials are needed in order to draw robust conclusions with regard to its efficacy in chemotherapy-induced side effects.
