Adjuvant 6 Cycles of Docetaxel and Cyclophosphamide or 3 Cycles of Cyclophosphamide/Epirubicin/Fluorouracil Followed by 3 Cycles of Docetaxel Versus 4 Cycles of Epirubicin and Cyclophosphamide Followed by Weekly Paclitaxel in Operable Breast Cancer (MASTER)

Adjuvant Six Cycles of Docetaxel and Cyclophosphamide or Three Cycles of Cyclophosphamide/Epirubicin/Fluorouracil Followed by Three Cycles of Docetaxel Versus Four Cycles of Epirubicin and Cyclophosphamide Followed by Weekly Paclitaxel in Operable Breast Cancer

We aimed to evaluate the noninferiority of a short-term anthracycline-free chemotherapy (TC, six cycles of docetaxel and cyclophosphamide) or a short-term anthracycline-based chemotherapy (CEF-T, three cycles of cyclophosphamide/epirubicin/fluorouracil followed by three cycles of docetaxel) to a standard anthracycline/taxane-containing chemotherapy (EC-P, epirubicin and cyclophosphamide for four cycles followed by paclitaxel for twelve weeks) in operable breast cancer.

Study Overview

• Status: Completed
• Conditions: Primary Breast Cancer
• Intervention / Treatment: Drug: Docetaxel; Drug: Cyclophosphamide; Drug: Epirubicin; Drug: 5-fluorouracil; Drug: Paclitaxel

Detailed Description

It was initiated as an adjuvant chemotherapy trial in 2010 to test noninferiority of an anthracycline-free short-term regimen (T75C600 x 6 [TC] once every 3 weeks) or a short-term regimen (C500E100F500 x 3 once every 3 weeks followed by T100 x 3 every 3 weeks [CEF-T]) compared with a standard long-term anthracycline-containing regimen (E90C600 x 4 once every 3 weeks followed by P80 x 12 once every week [EC-P]). Patients were randomly assigned (1:1:1) to each arm after completing surgical excision of primary tumor. Trastuzumab was administered in combination with chemotherapy to patients with HER2-positive breast cancer and sustained monotherapy as per the current guidelines.
