JADWIGA Nowak studied the efficacy and safety of combining Ccarica papaya Linn (CP), Vernonia amygdalina Delile (VA), artemis- inin (DHA) and iodine as potential agents in the management of breast cancer. She found out that the combination of CP + VA presented the strongest cytotoxic and synergistic activity against MCF-7 and additive activity on MDA-MB-231 breast cancer cell lines respectively and had a minimal cytotoxic effect on PBMCs compared to doxorubicin (DOX). Despite the combination index (CI) >1 combination of CP+VA+DHA was included in the study based on its possible multi-target mechanism of action. The cytotoxicity of most efficacious formulations was found to be more selective towards cancer cells compared to DOX and generally non-toxic in rat models with regard to the effect on body weights and histopathology, however, some hematological and biochemical parameters of tested rats showed significant changes. Additionally, UHPLC-MS analysis of Ugandan ori- gin CP and VA provided new data on their phenolic composition giving a new research perspective on the possible mechanisms of their bio-logical activity. It is recommended that the best treatment outcomes are further explored for the development of effective herbal therapy against breast cancer.
