Alpha-Lipoic Acid in Breast Cancer Patients

Damanhour University64 enrolled

Overview

• Investigate the ability of alpha lipoic acid to counter act anthracycline associated cardiotoxicity and cumulative taxens-related PN in patients with breast cancer.

Fifty breast cancer patients with stage from stage I to stage III will be involved in this study. Staging is done according to the American joint committee on cancer: TNM staging of breast cancer. * All participants will be recruited from Tanta Oncology Center. The study will be approved by Research Ethics Committee of Damanhour University. All participants will give their consent. * All 64 patients will be scheduled to receive 4 cycles of AC: cycled every 21 days followed by weekly cycle of taxol for 12 weeks. Patients will be classified as follow: * Group one: 32 patients will receive four cycles of AC followed by weekly taxol for 12 weeks plus placebo. * Group two: 32 patients will receive the same regimen as group 1 in addition to oral 600 mg alpha lipoic acid (ALA) once daily. All patients will be submitted to: 1. Full patient history and clinical examination. 2. Venous blood will be collected before the first cycle of chemotherapy and after the last cycle of chemotherapy. 1- Cardio-toxcity assessment: i. Echo-cardiogram. ii. Troponin I. iii. The Brain Natriuretic Peptide (BNP). 2- Neurotoxicity assessment: i. National Cancer Institute common Terminology criteria for Adverse Effect grading: NCI-CTCAE version 4.0. ii. Neurotoxicity questionnaire from the validated Functional Assessment of cancer therapy/gynecologic oncology group taxane specific neurotoxicity questionnaire: FACT-Taxane. iii. Neurotensin 3- Oxidative stress and inflammatory markers: i. Malondialdehyde (MDA). ii. TNF-alpha

Inclusion Criteria: 1. All patients age ≥ 18 and \< 70 years old with confirmed stage from stage I to stage III. 2. No evidence of metastases at initial assessment. 3. Patients has to have a good performance status (ECOG 0-2) according to Eastern Cooperative Oncology Group (ECOG) score. 4. Adequate baseline hematologic values (absolute neutrophilic count ≥ 1.5 × 109/L, platelet count ≥ 100 × 109/L, and hemoglobin level ≥ 10g/dL). 5. Patients with adequate liver function (serum creatinine \< 1.5 mg/dL) and adequate renal function (serum creatinine \< 1.5 mg/dL, creatinine clearance (CrCl) \> 45 ml/min). 6. Either pre operative or post operative chemotherapy are allowed. Exclusion Criteria: 1. Evidence of metastases at initial assessment. 2. Pregnancy or breast-feeding patients. 3. Prior exposure to neurotoxic chemotherapy was not allowed (no carboplatin, vincristine, vinblastine, paclitaxel, or docetaxol ) for 6 months prior study treatment. 4. Clinical evidence of serious cardiac illness (myocardial dysfunctional, angina pectoris requiring anti-angina medication, poorly controlled hypertension, and uncontrolled arrhythmias). 5. Patients with a reduced cardiac output with a left ventricular ejection fraction (LVEF) ejection fraction \< 50%. 6.
