UNLABELLED Imaging of osteomyelitis and soft-tissue infections can be problematic with currently available agents; bone scans are often false-positive. Indium-111-oxine and 99mTc-HMPAO white blood cell (WBC) scans require ex vivo handling of blood with potential exposure to infectious agents, and 99mTc-antigranulocyte (IgG1) antibodies need 24 hr for final diagnosis. METHODS We investigated t...
The natural history of prostate cancer is notoriously variable and whilst some tumours remain indolent for many years, others result in rapid progression to metastasis and death. A substantial minority of patients treated with radical prostatectomy or radiotherapy with curative intent have rising levels of PSA in their serum after treatment, and this is often associated with the eventual develo...
Thirteen patients with metastatic breast carcinoma were given injec dons of 50—1593@ag of †̃311-monoclonal antibody (MAb) B6.2 immuno globulin G and F(ab')@for pharmacokinetic evaluation and radioimmu noimaging. Blood clearance of the †̃31I-MAb-B6.2 was biphasic. The mean half-times (t@, t@.,)for the immunoglobulin G were 33 ±1.7 and 20.9 ±11.0 h, respectively. The t@ for the F(ab'>@was 1...
For immunoscintigraphic localization of human breast cancer two monoclonal antibodies (mabs) 12H12 (immunoglobulin G1) and BM-2 (immunoglobulin G3) were developed. The mabs, directed against two different epitopes on the mucin glycoprotein TAG-12, showed reactivity with 96% of all primary mammary carcinomas. The antibodies were labeled with either 125I or 131I. In addition, 12H12 was directly l...
سابقه و هدف: آنتی بادی های مونوکلونال (monoclonal) با توجه به اتصال اختصاصی به آنتی ژن، امروزه به عنوان ابزار تحقیقاتی و عوامل تشخیصی بهسازی می شوند. در این تحقیق آنتی بادی های مونوکلونال بر علیه سلول های سرطان روده تهیه شده و نشان دارسازی آن ها با رادیوایزوتوپ تکنسیم - 99m صورت گرفت.مواد و روش ها: این پژوهش در سه مرحله انجام شد که شامل تهیه سلول های هیبریدوما علیه سلول های سرطانی روده (ht29)، ...
PURPOSE Standard imaging for assessing osseous metastases in advanced prostate cancer remains focused on altered bone metabolism and is inadequate for diagnostic, prognostic, or predictive purposes. We performed a first-in-human phase I/II study of (89)Zr-DFO-huJ591 ((89)Zr-J591) PET/CT immunoscintigraphy to assess performance characteristics for detecting metastases compared with conventional ...
This pharmacokinetic study was performed to assess the potential usefulness of the murine monoclonal antibody (MoAb) PAM4-IgG, as an immunotargeting agent for pancreatic cancer imaging or therapy. This MoAb reacts specifically with mucin purified from human pancreatic cancer. †̃311-labeled PAM4-IgG, was injected i.v. into five patients with sus pected pancreatic cancer. Whole-body scans and sp...
