6xFU/Epirubicin/Cyclophosphamide (FEC) Compared to 3xFEC-3xDocetaxel in High-risk Node-negative Breast Cancer Patients

Phase 3

• Conditions: Breast Cancer
• Interventions: Drug: 5-Fluorouracil, Epirubicin, Cyclophosphamide, Docetaxel

• Registration Number: NCT01222052
• Lead Sponsor: Martin-Luther-Universität Halle-Wittenberg

Brief Summary

In low-risk node-negative breast cancer patients adjuvant chemotherapy should be spared. The identification of this subgroup can be based either on clinical and pathological or on tumour-biological criteria. Due to their high prognostic impact, the tumour-biological invasion markers uPA/PAI-1 (urokinase-type plasminogen activator and its inhibitor PAI-1) are potential candidates to effectively assess the risk of relapse in node-negative breast cancer. This study is aimed to compare the risk assessment by the traditional clinico-pathological factors and by tumour-biological factors. The second study question refers to the comparison between an adjuvant combination treatment with FE100C\*6 and a sequential treatment with FE100C\*3 and Docetaxel\*3.

Detailed Description

1. To compare FEC\*6 with FEC\*3 followed by DOC\*3 with regard to:

* the primary endpoint of the study: Disease-Free Survival (DFS)

* the secondary endpoints: Overall Survival (OS), compliance, and toxicity of chemotherapy in each patient group

2. To compare patients with low risk according to clinico-pathological versus those according to biological risk criteria with regard to:

* the proportion of low risk versus high risk patients

* DFS

* OS (secondary endpoint)

Recruitment & Eligibility

• Status: UNKNOWN
• Sex: Female
• Target Recruitment: 4150

Inclusion Criteria

• Histological proven primary breast cancer
• Tumour size >0.5 cm and <5 cm (pT1b-pT2, pN0, M0)
• Axillary lymph nodes tumour free (node-negative disease)
• Adequate surgical procedure: R0-resection and axillary dissection with more than 10 lymph nodes examined or adequate sentinel procedure in a qualified centre
• Frozen tumour tissue available (for analysis of biological markers and microarrays, centres with biological risk assessment only). The material has to be stored in liquid nitrogen immediately after excision.
• Paraffin blocks or (at least) pathology slides of primary tumour (stained and unstained) and axillary nodes (stained) available for central review.
• HER-2/neu determination by immunohistochemistry. Patients will be stratified to be HER-2/neu-negative or HER-2/neu-positive (HER-2/neu Score 3+, or HER-2/neu Score 2+ and FISH positive).
• No distant metastasis
• Age >18 years, <70 years
• Performance status ECOG <2 (WHO Performance Status 0-1)
• Adequate cardiac function (echocardiographically measured left ventricular ejection fraction (LVEF) or shortening fraction (SF) within the normal limits, i.e. ≥55%)
• Adequate bone function (neutrophil count >1.5 x109 /l and platelet count >100 x109 /l)
• Adequate renal function (serum creatinine <120 µmol/l or 1.35 mg/dl) and hepatic function (serum bilirubin <1 x UNL, ASAT or ALAT (SGOT or SGPT) <2,5 x UNL)
• Before patient registration/randomization, written informed consent must be obtained according to ICH/EU GCP, and national/local regulations

• Pregnancy, lactation (sufficient non-hormonal contraception in fertile women required)
• Surgery more than six weeks ago at the start of chemotherapy
• Pre-existing polyneuropathy
• Previous or concomitant other malignancy (including contralateral breast cancer) except adequately treated basal or squamous cell carcinoma of the skin or in situ carcinoma of the cervix
• Prior chemotherapy or radiotherapy or endocrine therapy
