Vascularity and uptake of photosensitizer in small human tumor nodules: implications for intraperitoneal photodynamic therapy.

Abstract

We conclude that STNs, as small as 1 mm in diameter, have a functional vasculature, because these tumors show PF uptake after i.v. delivery. Both properties are crucial for the treatment of residual STNs by IP-PDT after surgical debulking.
