Inclusion Criteria:

* Patients \>18 years affected by advanced or metastatic colorectal cancer (CRC), previously treated with fluoropyrimidine, oxaliplatin and irinotecan based regimens, but not more than three lines of therapy.

  * ECOG Performance status 0 - 1
  * Patients in progression disease at study entry, CT documented
  * Adequate baseline bone marrow, hepatic and renal function, defined as follows:
* Neutrophils \> 1.5 x 10\^9/L and platelets \> 100 x 10\^9/L
* Bilirubin \< 1.5 x ULN
* AST and/or ALT \< 2.5 x ULN in absence of liver metastases
* AST and/or ALT \< 5 x ULN in presence of liver metastases
* Serum creatinine \< 1.5 x ULN

  * Absence of any conditions in which hypervolemia and its consequences (e.g. increased stroke volume, elevated blood pressure) or hemodilution could represent a risk for the patient (reference appendix "Technical data sheet human albumin")
  * Normal cardiac function and absence of uncontrolled hypertension
  * Patients must give written informed consent to participate in the study

Exclusion Criteria:

* More than three lines of chemotherapy (except biological agents)
* Concurrent anticancer therapy
