Interventions

Patients in this study will be treated with Cofactor (5,10-Methylenetetrahydrofolate), in 100 mg vials, at a dose of 60 mg / m2 / day, administered in an IV bolus infusion, for 2-3 minutes + 5- Fluorouracil, in 10 ml ampoules containing 50 mg / ml of the drug, at a dose of 500 mg / m2 / day, in an IV bolus infusion, for 2-3 minutes, 20 minutes after the Cofactor infusion. This scheme will be administered once a week for 6 weeks, each treatment cycle lasting 8 weeks, until the progression of the

Patients who have failed with both previous chemotherapy regimens with anthracycline and taxane derivatives.

Exclusion criteria

Exclusion criteria: 1. Positive tumor Her2 / neu 2+ or 3+. 2. Pregnancy or lactation. 3. Systemic cytotoxic anticancer therapy, within ≤ 4 weeks of enrollment or 6 weeks if systemic therapy contains a nitrosourea or mitomycin. 4.

Design outcomes

Primary

MeasureTime frame
Outcome name:Clinical and imaging evaluation (MRI, CT) of the presence or absence of a confirmed objective response. Which is defined as a Complete Response (CR) or a Partial Response (PR), according to the RECIST criteria. Where CR is the disappearance of all target lesions and PR is a 30% decrease in the sum of the larger diameters of the target lesions. Measure:Rate of confirmed objective answers. Timepoints:At the end of each treatment cycle of 8 weeks, at the end of the study and during the follow-up.

Secondary

MeasureTime frame
Outcome name:Criterion 1: Determination of the time from the randomization until reaching the Objective Response criteria (determined previously). Criterion 2: Determination of the time elapsed from the entrance to the study to the progression of the disease (according to the RECIST criteria) or death. The progression of the disease is defined as: 1) For white lesions: Increase of 20% in the sum of the larger diameters or the appearance of one or more new lesions. 2) For non-white lesions: Occurrence of one or more new lesions and / or unambiguous progression of the existing lesions. Criterion 3: Determination of the time elapsed from entry into the study to death from any cause. Measure:Secondary efficacy: 1) Target response duration. 2) Free survival of progression (PFS). 3) Total survival. Timepoints:When the requirements for any of the criteria are met. ; Outcome name:Criterion 1: Toxicity will be assessed and classified according to the Common Terminology Criteria for Adverse Events of the NCI - Version 3.0 of the Cancer Therapy Evaluation Program (DCTD - NCI). Criterion 2: Clinical evaluation of all adverse events that generate inability to work or develop normal daily activities. Criterion 3: Determination of the number of patients who discontinue the medication due to some toxicity. Criterion 4: Panels of hematology and serum chemistry, laboratory analysis. Measure:Safety: 1) Incidence and safety of toxicity. 2) Incidence of Serious Adverse Events. 3) Incidence of treatment discontinuation due to toxicity. 4) Laboratory tests. Timepoints:Criteria 1, 2 and 4: Weeks 1-8 of the first cycle and in each subsequent treatment cycle. Criterion 3: When the event is presented.
