The role of coenzyme Q10 in breast cancer
Journal Title: Journal of Pharmaceutical and Biomedical Sciences - Year 2016, Vol 6, Issue 9
Abstract
Oxidative stress plays a crucial role in pathogenesis as well as progression of all cancers including breast cancer. The aim of the present study was to explore the possible protective effects of coenzyme Q10, an antioxidant agent, on Doxorubicin induced cardiotoxicity in breast cancer patients, we also investigated the role of coenzyme Q10 on oxidative stress. Sixty-four women having histologically confirmed breast cancer participated in this study. The patients divided into two groups. Group (A) who treated with coenzyme Q10 supplement in addition to chemotherapy adriamycin plus cyclophosphamide (AC). Group (B) treated with chemotherapy only. In this study, serum coenzyme Q10, malondialdehyde (MDA), total antioxidant status (TAS), complete blood count (CBC), serum ALT, AST, creatine kinase (CK), renal functions (serum creatinine and urea), creatine phosphokinase (CPK), high sensitivity C-Reactive protein (hs-CRP) levels were determined. Ejection Fraction (EF) was determined by echocardiography for all participants at baseline as well as post treatment. Statistical analysis was performed using SPSS, version 23, USA for WINDOWS, results are defined as mean ± standard deviation SD. Serum coenzyme Q10, total antioxidant status (TAS) were low at baseline in both groups, serum malondialdehyde (MDA), high sensitivity C-reactive protein (hs-CRP) levels had decreased significantly after supplementation with coenzyme Q10. The reduction in EF was more pronounced in group B at the end of the work. The present study demonstrated that women with breast cancer have a low level of coenzyme Q10 as compared to those of healthy women. It also emphasizes the growing concern that oxidative damage may occur in those patients that exhaust the antioxidant defense of the body leading to a low levels of Coenzyme Q10 and TAS and increasing in inflammatory markers as well as oxidative stress markers which lead to cardiotoxicity. Administration of antioxidant supplements such as a coenzyme Q10 is necessary in women with breast cancer postoperative with adjuvant chemotherapy to minimizes its cardiotoxicity.
