They determined that the correct RIGS identification of tumor sites occurred in 80.4% of the 125I-B72.3 monoclonal antibody group and in 92.6% of the 125I-F023C5 monoclonal antibody fragment group, with additional occult sites of tumor identified by RIGS that would modify surgical strategy in 23.3% of the 125I-B72.3 monoclonal antibody group and in only 8.8% of the 125I-F023C5 monoclonal antibody fragment group. This evidence concerns the gene CD86 and neoplasm.
