Abstract

This section provides current contact details and a summary of recent or ongoing clinical trials being coordinated by German Breast Group (GBG). Clinical trials include: A multi-center randomized Phase III study evaluating 4 cycles of docetaxel, doxorubicin and cyclophosphamide (TAC) versus 4 cycles of vinorelbine and capecitabine (NX) in patients not sufficiently responding to 2 cycles of TAC and 4 cycles of TAC versus 6 cycles of TAC in patients sufficiently responding to 2 cycles of TAC as preoperative treatment of locally advanced (T4 a-d, N0-3,M0) or operable (T ≥ 2 cm, N0-2,M0) primary breast cancer/GBG 24.A multi-center randomized Phase III study to compare capecitabine alone or in combination with trastuzumab in patients with HER-2 positive metastatic breast cancer and progression after previous treatment with trastuzumab (Treatment Beyond Progression, TBP).

A joint study of GBG and AGO / GBG 40.Randomized study comparing 6 × FEC with 3 × FEC followed by 3 × docetaxel in high-risk node-negative patients with operable breast cancer: comparison of efficacy and evaluation of clinico-pathological and biochemical markers as risk selection criteria. A joint study of AGO, the EORTC Receptor and Biomarker Group, and the GBG (GBG 42 / NNBC 3-Europe).
