Introduction: The radioimmunoscintigraphy (RIS) has found widespread clinical applications in  tumor  diagnosis.  Human  epithelial  mucin,  MUC1,  is  commonly  over  expressed  in  adenocarcinoma including 80% of breast cancers and represents a useful target for RIS. The PR81  is  a  new  murine  anti-MUC1  monoclonal  antibody  that  was  found  to  react  with  the  membrane  extracts of se...

Monoclonal antibody scintigraphy with 111In-ZCE025 was used in presurgical staging of 45 patients prior to abdominal exploration for primary, recurrent or metastatic colorectal carcinoma. A total of 186 lesions were identified, of which 147 were evaluated by abdominal surgery and pathology. Sensitivity was 40.5% (49 of 121) for immunoscintigraphy (IS), 61.2% (74 of 121) for computerized tomogra...

BACKGROUND Vascular endothelial E-selectin expression is induced by proinflammatory cytokines and contributes to accumulation of leucocytes in tissues. AIMS To investigate the role of E-selectin in inflammatory bowel disease (IBD). METHODS E-selectin expression was assessed in patients with ulcerative colitis and Crohn's disease by measuring the concentration of circulating soluble E-select...

Experience in using rapidly internalizing antibodies, such as the anti-CD22 antibody, for radioimmunotherapy of B-cell lymphomas is still limited. The present study was conducted to assess the efficacy and toxicity of a 131I-labeled anti-CD22 monoclonal antibody (mAb), LL2, in patients with B-cell lymphomas failing first- or second-line chemotherapy. Eligible patients were required to have meas...

A radiolabeled monoclonal antibody (MAb) that has been shown to react specifically in vitro and ex vivo to human colorectal carcinoma and to inhibit growth of human carcinomas grafted in nude mice was administered to 52 colorectal carcinoma patients and 15 patients with other types of cancer. Of 63 colorectal carcinoma tumor sites studied, 34 showed significant accumulation of antibody by exter...
