Intraperitoneal distribution imaging in ovarian cancer patients

Abstract

BACKGROUND/AIMS: Optimal delivery of intraperitoneal (i.p.) chemotherapy is dependent on adequate drug distribution. An accurate understanding of the limitations of i.p. distribution is critical if we are to improve cytotoxic delivery through this route. METHODS: Using repeated scintigraphic peritoneography we investigated peritoneal fluid distribution in patients receiving i.p. therapy. Both early (1-6 h) and late (24-48 h) images were performed. The peritoneal cavity was divided into six regions; pouch of Douglas, left and right paracolic gutters, left and right subphrenic spaces and the right subhepatic space. The distribution in each region was classified as absent (0), faint (1) or inte..
