Overview
Brief Summary
The purpose of this clinical trial is to primarily assess the efficacy of an intensified chemotherapy consisting of a combination of FOLFOXIRI + bevacizumab. The main focus will be laid on the rate of patients who achieve secondary complete (R0)-resectable metastases.
The FOLFIRI + bevacizumab as well as the FOLFOXIRI regimens have been shown previously to be both effective in the treatment of advanced CRC with having manageable toxicities. Therefore, an intensified chemotherapy combining these two standard regimens might be a promising therapeutic approach improving the treatment of metastatic disease and outcome of CRC.
Patients with advanced colorectal carcinoma of UICC stage IV, and liver and/or lung metasta¬ses only, which are not optimally resectable, will be enrolled in this single-arm phase II study.
A minimum of 4 cycles (=8 weeks) of chemo¬therapy prior to surgery is mandatory for all patients. However, patients may withdraw from the study at any time upon their own request. Treatment with preoperative chemothera¬py will continue until 2-4 weeks prior to surgery with the last application of bevacizumab (only FOLFOXIRI) 4 weeks before surgery, at longest 16 cycles (= 32 weeks) for candidates not eli¬gible for surgery. Treatment will be discontinued prematurely at disease progression or unacceptable toxicity.
As secondary endpoints the acute and perioperative toxi¬city of preoperative chemotherapy according to NCI CTCAE v 3.0 including all peri-and post-surgical complications as well as progression free survival and overall survival and quality of life will be assessed.

- •Measurable disease according to RECIST criteria.
- •In case of liver metastases: 70% liver replacement and/or \> 6 segments tumor involved, and/or involvement of all three hepatic veins, and/or involvement of the right and left portal pedicle, and/ or involvement of the vena cava.
- •In case of lung metastases: No tumor with direct infiltration of myocardium, esophagus, spine or intrapericardial large vessels. Preoperative data indicate a significant loss of pulmonary function after pulmonary metastasectomy with severe impairment of quality of life.

Exclusion Criteria
- •Past or current history of malignancies other than colorectal carcinoma. Patients with curatively treated basal and squamous cell carcinoma of the skin and/or in-situ carcinoma of the cervix are eligible.
- •Previous chemotherapy (except adjuvant chemotherapy).
- •Extrahepatic and/or extrapulmonary meta-stases except of the initially removed lymph node metastases.
- •History or evidence upon physical examination of CNS disease unless adequately treated (e.g., seizure not controlled with standard medical therapy or history of stroke).
- •Major surgical procedures, open biopsy, or significant traumatic injury within 28 days prior to study treatment start (wound healing has to be completed), or anticipation of the need for major surgical procedure during the course of the study.
- •Evidence of bleeding diathesis or coagulopathy
- •Serious, non-healing wound, ulcer, or bone fracture
- •Treatment with investigational agents or participation in clinical trials within 30 days before study entry.
- •Clinically significant (i.e. active) cardiovascular disease, e.g., uncontrolled hyper-tension, cerebrovascular accidents (. 6 months prior to treatment start), myocardial infarction (. 6 months prior to treatment start), unstable angina, New York Heart Association (NYHA) grade . II, congestive heart failure, serious cardiac arrhythmia requiring medication.
- •Current or recent serious polyneuropathy (grade . 1 according to NCI CTCAE v3.0 criteria; exception: absence of tendon reflexes)
