Brief Summary:
The trial investigates the effect of oral supplement of molecular iodine (I2) alone and in combination with 4 to 6 cycles of FEC/TE (5-fluorouracil, epirubicin, cyclophosphamide/taxotere, epirubicin) treatment in woman diagnosticated with early (stage II) and advance (stage III) breast cancer, respectively. The study analyzes the clinical response [tumor size, thyroid status, side effects (Common Toxicity Criteria V4.0)] and molecular mechanisms in the tumor samples (transcriptomic, proteins and immune responses).

Breast Cancer Drug: Placebo Drug: iodine Drug: FEC/TE Placebo Drug: FEC/TE iodine Phase 2

Detailed Description:
The leading causes of failure of breast cancer treatment are the rapid development of metastases and tumor resistance to antineoplastic drugs. Anthracyclines (doxorubicin (DOX), epirubicin, etc.) are the golden standard in neoadjuvant therapy and are commonly used in the FEC/TE (5-fluorouracil, epirubicin, cyclophosphamide/taxotere, epirubicin) combination therapy during advanced breast cancer. However, even when treated with this potent chemotherapeutic combination, 30% of patients develop chemoresistance and cardiomyopathic side effects. Previous studies support that the oral supplement of molecular iodine (I2) exerts synergistic antineoplastic and cardioprotective impact when used in combination with the DOX in rodent and canine mammary cancer model. The present study performed two randomized clinical groups including women with early (stage II) and advanced (stage III) breast cancer. In the Early group, women were treated with I2 (5 mg/day) or placebo (colored water) for 7 to 35 days. In the Advanced group, patients received treatment (I2 or placebo) along with 4 to 6 cycles of FEC/TE treatment. The study analyzes the clinical response [tumor size, thyroid status, side effects (Common Toxicity Criteria V4.0)] and molecular mechanisms in the tumor samples (transcriptomic, proteins and immune responses).

Primary Outcome Measures :
  1. Tumor response [change in size] [ Time Frame: 20 minutes ]
    The size of the tumor is calculated by measuring the largest diameter of the tumor in the axial plane. The first measurement is obtained in the mammography taken before the start of the protocol and the second measurement is made on the tissue after surgery. The change percentage is obtained by dividing the final size between the initial size by 100.

  2. Incidence of treatment-emergent adverse events [Safety and Tolerability]). [ Time Frame: 40 minutes ]
    Presence or not of: Edema, hand-foot syndrome, anorexia, vomiting, diarrhea, nausea, asthenia (patient interview and clinical auscultation)

  3. Differential Blood Count [ Time Frame: 10 minutes (duration of blood withdrawal)] ]
    Differential blood count gives relative percentage of each type of white blood cell and helps reveal abnormal white blood cell populations (eg, blasts, immature granulocytes, or circulating mature cells in the peripheral blood).

  4. Thyroid Test [ Time Frame: 10 minutes (duration of blood withdrawal) ]
    Serum quantification of thyroxine, triiodothyronine, and thyroid stimulating hormone (nmol/ml) by ELISA Method

  5. Cardiac damage [ Time Frame: 10 minutes (duration of blood withdrawal) ]
    Measurement of creatine kinase myocardial band (CK-MB) concentration in serum (ImU/ml) by Colorimetric Method.

  6. Iodine consumes [ Time Frame: 10 minutes (duration of urine recollection) ]
    Measurement of iodine concentration in urine (ug/mL) by Ion Chromatography Method.

  7. Tumor classification type and modification after treatment [ Time Frame: 40 minutes ]
    Estrogen receptor (ER), Progesterone receptor (PR) and Human epidermal growth factor receptor 2 (HER2) presence in biopsy (initial) and tumor sample after treatments (final) by immunohistochemical method (number of positive cells/field).


Secondary Outcome Measures :
  1. Disease-free survival [ Time Frame: Every 6 months for 5 years ]
    The follow-up of the disease-free survival (DFS) at 5 years. (patient interview and clinical auscultation each six months)
