Radioimmunotherapy (RIT or RAIT) dates back more than 2 decades and has evolved to encompass a variety of tumorseeking antibodies in various forms, with different radionuclides, different delivery methods, for different clinical indications (usually advanced disease).1 Although selective antibody targeting has been demonstrated, the radiation doses delivered have been insufficient to markedly i...
BACKGROUND AND OBJECTIVE Cytoreductive surgery (CS) and heated intraperitoneal chemotherapy (HIPEC) are standard treatment for peritoneal carcinomatosis (PC) of colorectal cancer. Previously, we demonstrated that preclinical radioimmunotherapy (RIT) adjuvant to surgery in PC is a good alternative for HIPEC. Now we aimed to improve the effectiveness of RIT by combining it with whole-body hyperth...
Radioimmunotherapy (RIT) potentially is an attractive treatment for radiosensitive early-stage solid tumors and as an adjuvant to cytoreductive surgery. Topical administration of RIT may improve the efficacy because higher local concentrations are achieved. We reviewed the results of locally applied radiolabeled monoclonal antibodies for the treatment of solid tumors. Intracavitary RIT in patie...
Radioimmunotherapy (RIT) prolongs the survival of mice infected with Cryptococcus neoformans. To compare the efficacy of RIT with that of amphotericin B, we infected AJ/Cr mice intravenously with either nonmelanized or melanized C. neoformans cells. Infected mice were either left untreated or treated 24 h after infection with (213)Bi-18B7 antibody, amphotericin B, or both. Melanization before i...
Timing effects of radioimmunotherapy (RIT) combined with external-beam radiotherapy (RT) were assessed in human colon carcinoma xenografts. Initially, dose effects of fractionated RT and RIT were evaluated separately. Then, 30 Gy RT (10 fractions over 12 days) were combined with three weekly i.v. injections of 200 microCi of 131I-labeled anti-carcinoembryonic antigen monoclonal antibodies in fo...
PURPOSE Melanin has emerged as an attractive target for radioimmunotherapy (RIT) of melanoma, and a radiolabeled monoclonal antibody (mAb) 6D2 to melanin is currently in clinical evaluation. We investigated two approaches to improve the targeting of radiation to tumors using melanin-binding mAbs: (a) the use of an additional mAb to melanin could provide information on whether using antibodies t...
BACKGROUND Chemoradiotherapy for head and neck cancer (SCCHN) is challenging in elderly, multi-morbid patients. Radioimmunotherapy (RIT) with cetuximab provides an option to enhance efficacy of radiotherapy without increased toxicity. We present a single-centre experience of RIT these patients. METHODS Toxicity and outcome was retrospectively analysed in patients treated with radiotherapy and...
The effect of combined radioimmunotherapy (RIT) and fractionated external beam radiotherapy (RT) was assessed in two human colon cancer xenografts, Co112 and LS174T in nude mice. These tumors were selected for being resistant to RIT alone, as is usually the case in the clinical situation. Tumor-bearing mice were treated with a combination of five X-ray fractions over 5 days followed by RIT with...
Radioimmunotherapy (RIT) with anti-CD123 monoclonal antibody CSL360 modified with nuclear translocation sequence (NLS) peptides and labeled with the Auger electron-emitter, (111)In ((111)In-NLS-CSL360) was studied in the prevalent NOD/SCID mouse AML engraftment assay. Significant decreases in CD123(+) leukemic cells and impairment of leukemic stem cell self-renewal were achieved with high doses...
