Hypofractionation With Simultaneous Integrated Boost vs. Standard Fractionation in Early Breast Cancer

Hypofractionation with simultaneous integrated boost has been investigated in a few trials and appears to be safe and feasible. Investigators initiated this multicenter two-armed phase III prospective trial to analyse the non-inferiority of hypofractionation with simultaneous integrated boost in patients with early breast cancer in comparison to standard fractionation.

Neoadjuvant Response-guided Treatment of Luminal B-type Tumors and Luminal A-type Tumors With Node Metastases

The purpose of this neoadjuvant trial is to evaluate efficacy and toxicity of chemotherapy using weekly paclitaxel (arm A) versus the combination of the cdk 4/6 inhibitor palbociclib and standard endocrine treatment (arm B). After 12 weeks treatment is switched crossover. During the 24-weekly treatment period, clinical and radiological evaluations are performed repeatedly. Switch between the treatment arms A and B is allowed in case of lack of response or due to toxicity. A translational subprotocol is a mandatory part of the study protocol, except for use of PET-CT evaluations. Postoperatively, patients receive three 3-weekly courses of chemotherapy with a combination of epirubicin and cyclophosphamide.

Neoadjuvant Response-guided Treatment of HER2 Positive Breast Cancer

The purpose of this trial is to evaluate efficacy and toxicity of either the combination of docetaxel, trastuzumab sc and pertuzumab (arm A) or trastuzumab emtansin (arm B). Switch of therapy to the opposite treatment alternative is applicable in case of lack of response after two courses of treatment, or for medical reasons under exceptional circumstances (drug reaction, other medical conditions) at any point. After termination of the primary treatment follow-up for five years. A translational subprotocol is a mandatory part of the study protocol, with exception for the use of PET-CT evaluations.

Neoadjuvant Response-guided Treatment of Slowly Proliferating Hormone Receptor Positive Tumors

The purpose of this neoadjuvant trial is to evaluate efficacy and toxicity of the cdk 4/6 inhibitor palbociclib when added to standard endocrine treatment. Initially, patients receive endocrine treatment for 4 weeks. In case of decrease of proliferation (Ki67) patients are then randomized between either continuous endocrine therapy (arm A) or the same treatment with addition of palbociclib (arm B). Patients with no change of proliferation are allocated to endocrine treatment + palbociclib without randomization (arm C). During the 12-weekly treatment period, clinical and radiological evaluations are performed repeatedly. Switch between the treatment arms A and B is allowed in case of lack of response or due to toxicity. A translational subprotocol is a mandatory part of the study protocol, except for use of PET-CT evaluations.
