Recent studies have shown that systemic injection of anti-VEGF antibody into tumor-bearing mice results in decreases in tumor vascular permeability, vessel diameters, and tumor regression. Using a similar animal model, we have applied anti-VEGF antibody directly to the tumor tissue growing in transparent window chambers in SCID mice. Similar to the results obtained with systemic injection, vascular permeability was greatly reduced, but the response was reached at much lower concentrations with local application. Implications of these findings on local control of tumors are discussed.
