OUTLINE: This is a dose escalation study. Patients receive monoclonal antibody F19 (BIBH-1) combined with iodine I 131 IV over 60 minutes. Patients undergo surgical resection approximately 7 days after BIBH-1 infusion. Cohorts of 3-6 patients receive escalating doses of BIBH-1 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 6 patients experience dose limiting toxicities. Patients are followed once during days 5-14 and then at day 30 after surgery.
