Abstract

Background: Breast cancer is one of the most common diseases globally that may have side effects on liver and renal function. Pharmacological treatments to reduce adverse liver and renal effects are still limited. It has been proposed that silymarin may possess hepatoprotective and anti-inflammatory properties. The present trial aims to assess the hepatorenal protective efficacy of silymarin supplementation in cancer patients receiving chemotherapy in an outpatient setting. Method: This is a randomized, placebo-controlled clinical trial that recruited female breast cancer patients. Participants were randomly assigned to one placebo group and two intervention groups. The control group received 140 mg of placebo daily, while the two intervention groups received 140 mg silymarin daily. Follow-up assessments were conducted at baseline, 3 weeks, and 6 weeks. At the beginning of the study, the patients were subjected to a computed tomography (CT) scan, and the liver and renal parameters such as alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), bilirubin, Blood urea nitrogen (BUN) and Creatinine (Cr) were examined through laboratory tests. Results: Despite two deaths and three dropouts, 100 patients completed the study. Silymarin showed significant effects on liver enzymes in the levels of ALP and bilirubin (P < 0.05), with no significant impact on renal function in the levels of Blood urea nitrogen (BUN) and Creatinine (Cr) (P > 0.05). The medication was well-tolerated, with minimal reported side effects (P > 0.05). Discussion: The study suggests that silymarin may have hepato-renal protective potential in breast cancer patients and improve patient tolerance to chemotherapy. The data presented on the efficacy and safety of silymarin may provide stronger foundation for further trials and for a possible use in clinical practice.
