• Life expectancy more than 3 months.
• Adequate renal function: creatinine ≤ 1.5 x UL and calculated creatinine clearance ≥ 30 mL/min.
• Adequate level function: AST and ALT ≤ 2.5 x UL (≤ 5 x UL if liver metastases), bilirubin ≤ 1.5 x UL.
• Adequate haematological function: Hb ≥ 9 gr/dl, neutrophils ≥ 1,5 x 109 /l and platelets ≥ 100000 x 109/l.
• Urine dipstick for proteinuria < 2+. If urine dipstick is ≥ 2+, 24 hour urine must demonstrate ≤ 1 g of protein in 24 hours.
• No clinical evidence or history of metastatic CNS disease.
• No prior Bevacizumab treatment.

Exclusion Criteria:

• Patients who previously received bevacizumab.
• Prior chemotherapeutic treatment for metastatic CRC.
• Prior treatment with monoclonal antibodies.
• Clinical evidence of brain metastases or history or evidence upon physical examination of CNS disease unless adequately treated.
• Past or current history (within the last 5 years prior to treatment start) of other malignancies except metastatic colorectal cancer (Patients with curatively treated basal and squamous cell carcinoma of the skin or in situ carcinoma of the cervix are eligible).
• Clinically significant cardiovascular disease, for example CVA (≤ 6 months before treatment start), myocardial infarction (≤ 6 months before treatment start), unstable angina, NYHA ≥ grade 2, CHF, arrhythmia requiring medication, or uncontrolled hypertension.

• Current or recent (within 10 days prior to study treatment start) use of full-dose oral or parenteral anticoagulants or thrombolytic agent for therapeutic (as opposed to prophylactic) purposes. Patients receiving (or considered candidate to receive) anticoagulants agents as prophylaxis of cardiovascular risk, should continue (or start) the appropriate treatment at study entry.

• Serious, non healing wound, ulcer, or bone fracture.
• Major surgical procedure, open biopsy or significant traumatic injury within 28 days prior to treatment, or anticipation of the need for major surgery during the course of the study.
• Evidence of any other disease, metabolic dysfunction, physical examination finding or laboratory finding giving reasonable suspicion of a disease or condition that contraindicates the use of an investigational drug or puts the patient at high risk for treatment-related complications.
• Patients of childbearing potential not willing to use effective means of contraception.
• Positive HIV serology.
• Known addiction to alcohol or other drugs.
