Metastasis controlled by blood vessel lining cells

without overt appear to be “tumor-free” upon surgical removal of the . Yet, metastatic spread of may already have occurred at the time of surgery. Many are consequently treated with chemotherapy after surgery to fight metastasis. This may be necessary in patients with detectable metastases, but what kind of more gentle treatment options can be offered in patients without overt metastasis?
