The computer tomography-guided wire marking of the metastases in the liver is a possibility to overcome these problems. All patients with complete radiologic response of metastases in the liver and metastases ≤ 1 cm are included in the study (RECISTE-Criteria). On day of surgical procedure patients will brought to interventional radiologist and based on computer tomography images before neoadjuvant chemotherapy the lesions will be marked computer tomography-guided with a wire(X-Reidy Breast Lesion Localization Needle, Cook Medical). The wire is placed percutaneously and under antibiotic prophylaxis. After the marking procedure, the patient is brought into the operating room to resect the metastases in the liver.
