CoRN at last for breast cancer!

CoRN  at last for breast cancer!

Dr. Weeks’ Comment: CoRN (Co Q 10, Riboflavin and Niacin) are essential nutrients for those suffering with both breast cancer and chemotherapy.  Does your oncologist know this?

BACKGROUND: Tamoxifen (TAM) a non-steroidal antiestrogen, is widely used in adjuvant therapy for all stages of breast carcinomas and in chemoprevention of high-risk group. TAM also has estrogenic activity on liver and endometrium causing severe oxidative stress with various biochemical derangements. Coenzyme Q(10), Riboflavin and Niacin (CoRN) are well-known potent antioxidants and protective agents against many diseases including cancer. In this context, this study was undertaken to find if co-administration of TAM along with CoRN could alleviate the sole TAM-induced biochemical derangements in postmenopausal women with breast cancer. METHOD: The vitamin supplementation with TAM was given for a period of 90 days. Blood samples were collected at the base line, 45th and 90th day during the course of treatment. Various blood chemistry profiles were assessed in 78 untreated, sole TAM treated and combinatorial treated group along with 46 age- and sex-matched controls.

 
RESULTS: A statistically significant alteration in various blood chemistry parameters, such as serum total bilirubin (S. BIL), serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), gamma glutamyl transpeptidase (gamma-GT), uric acid (UA), lipoprotein lipase (LPL), lecithin: cholesterol acyl transferases (LCAT), potassium, calcium and Na(+), K(+)-ATPase in sole TAM-treated group, was favorably reverted back to near normal levels on combinatorial therapy with CoRN.
 
CONCLUSION: TAM on co-administration with CoRN has a favorable impact on various blood chemistry profiles. However, large scale randomized studies over a longer time span are required to ascertain the safety and efficacy of co-administrating antioxidants with conventional chemotherapy.

Augmented antioxidant status in Tamoxifen treated postmenopausal women with breast cancer on co-administration with Coenzyme Q10, Niacin and Riboflavin.

BACKGROUND: Reactive oxygen species (ROS) such as superoxide anion, hydrogen peroxide (H(2)O(2)), hydroxyl radical have been implicated in pathogenesis of various diseases including cancer and metastasis. Tamoxifen (TAM) is a non-steroidal anti-estrogen drug most widely used as an adjuvant hormonal therapy in breast cancer. TAM also has estrogenic activity on liver and endometrium causing severe oxidative stress and hypertriglycerdemia. Coenzyme Q(10) (CoQ(10)), Niacin and Riboflavin are well-known potent antioxidants and protective agents against many diseases including cancer. In this context, this study was undertaken to find if co-administration of CoQ(10), Niacin and Riboflavin along with TAM could augment the antioxidant (AO) status in postmenopausal women with breast cancer. METHODS: The vitamin supplementation with Tamoxifen was given for a period of 90 days. Blood samples were collected at the base line, 45th and 90th day during the course of treatment. Plasma lipids, lipid peroxides and various circulating enzymatic and non-enzymatic antioxidants were estimated in 78 untreated, sole TAM treated and combinatorial treated group along with 46 age- and sex-matched controls.

 
RESULTS: Enhanced oxidative stress as evidenced by increased lipids and lipid peroxides with decreased AO levels in untreated breast cancer patients was observed. Adjuvant TAM-treated group had a limited impact on the increased oxidative stress with decreased AO status. Severe hypertriglycerdemia was observed in TAM-treated group when compared to untreated and control subjects. Combinatorial therapy (CT) of CoQ(10), Niacin and Riboflavin along with TAM decreased the oxidative stress and increased the AO status.
 
CONCLUSION: The antioxidant defense system is compromised in breast cancer patients. There is a shift in the oxidant / antioxidant balance in favor of lipid peroxidation (LPO), which could lead to tumour promotion observed in the disease. CT of CoQ(10), Niacin and Riboflavin along with TAM significantly increased the AO status, while decreasing lipid and lipid peroxides. The results suggest the necessity of therapeutic co-administration of antioxidants along with conventional drug to such patients. However, due to limited number of cases included in this study, more studies may be required to substantiate the results and arrive at a definitive conclusion, in terms of safety and efficacy of adding an AO therapy in treatment of breast cancer.
