Urine Protein and Avastin (Bevacizumab)

Avastin (Bevacizumab) is a good medication in metastatic bowel cancer (both colon and rectum). It is used for extended periods of time with chemotherapy to control and reduce the burden of cancer.

It is very important to check the urinary protein while on this medication, as it does have a potential to damage the functioning of the kidney. In case, the kidneys are secreting increased amounts of proteins, it is then important to check the quantity and then if needed to stop Avastin till the kidneys recover.

We have found that a significant number of doctors forget to check urine protein, while patients are on Avastin.
