RATIONALE: Radiolabeled monoclonal antibodies can locate tumor cells and deliver radioactive tumor-killing substances to them without harming normal cells. Giving radiolabeled monoclonal antibody directly into the abdominal cavity may kill more tumor cells.
PURPOSE: Phase I trial to study the effectiveness of giving radiolabeled monoclonal antibody therapy directly into the abdominal cavity in treating patients who have advanced ovarian epithelial cancer.
- Determine the safety and maximum tolerated dose of intraperitoneal yttrium Y 90 monoclonal antibody Hu3S193 (Y90 MOAB Hu3S193) in patients with advanced ovarian epithelial cancer.
- Determine the localization and whole body and abdominal clearance of this drug in these patients using indium In 111 monoclonal antibody Hu3S193 and gamma camera imaging.
- Determine the serum pharmacokinetics of Y90 MOAB Hu3S193 in these patients using gamma well counting.
- Determine the antibody response in patients treated with this drug.
OUTLINE: This is a dose-escalation study of yttrium Y 90 monoclonal antibody Hu3S193 (Y90 MOAB Hu3S193).
Patients receive intraperitoneal (IP) technetium Tc 99m sulfur colloid and undergo abdominal imaging on day 1. Provided distribution of technetium Tc 99m sulfur colloid is deemed adequate, patients then receive IP Y90 MOAB Hu3S193 and IP indium In 111 monoclonal antibody Hu3S193 (for imaging) over 30 minutes on day 1. Within 3-5 hours after antibody administration, patients undergo whole body imaging and single-photon emission-computed tomography (SPECT) imaging of the abdomen and pelvis.
Cohorts of 3-6 patients receive escalating doses of Y90 MOAB Hu3S193 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity.
Patients are followed every 3 months for at least 2 years and then every 6 months for up to 5 years.
PROJECTED ACCRUAL: A maximum of 42 patients will be accrued for this study.
Primary Purpose: Treatment

Stable yttrium atoms that have the same atomic number as the element yttrium, but differ in atomic weight. Y-89 is the only naturally occurring stable isotope of yttrium.
Unstable isotopes of yttrium that decay or disintegrate emitting radiation. Y atoms with atomic weights 82-88 and 90-96 are radioactive yttrium isotopes.
A humanized monoclonal antibody against the ERBB-2 RECEPTOR (HER2). As an ANTINEOPLASTIC AGENT, it is used to treat BREAST CANCER where HER2 is overexpressed.
An element of the rare earth family of metals. It has the atomic symbol Y, atomic number 39, and atomic weight 88.91. In conjunction with other rare earths, yttrium is used as a phosphor in television receivers and is a component of the yttrium-aluminum garnet (YAG) lasers.
