Prediction of effectiveness of intraperitoneal chemotherapy by intraperitoneal scintigraphy in patients with advanced ovarian carcinoma

Abstract

Intraperitoneal scintigraphy with Tc-99m MAA was performed in nine patients with carcinomatous peritonitis secondary to ovarian or tubal carcinoma. Tc-99m MAA (370 MBq) and NaCl was delivered through an implantable injection port. For patients with good diffusion on intraperitoneal scintigraphy, intraperitoneal chemotherapy was effective. However, for patients with only local diffusion, intraperitoneal chemotherapy was not effective. Intraperitoneal scintigraphy can predict the effectiveness Intraperitoneal scintigraphy can predict the effectiveness of chemotherapy through the implantable injection port.
