CONTEXT For the treatment of a single metastasis to the brain, surgical resection combined with postoperative radiotherapy is more effective than treatment with radiotherapy alone. However, the efficacy of postoperative radiotherapy after complete surgical resection has not been established. OBJECTIVE To determine if postoperative radiotherapy resulted in(More)
Carcinoembryonic antigen (CEA) is expressed in a wide variety of adenocarcinomas, and it is well recognized that cancer patients are immunologically "tolerant" to CEA. The purpose of this study was to determine whether we could break immune tolerance to CEA by vaccinating patients with a monoclonal anti-idiotype antibody that is the internal image of CEA(More)
Carcinoembryonic antigen (CEA) is a tumor-associated antigen expressed on most gastrointestinal adenocarcinomas and is a putative target for cancer immunotherapy. We developed a murine monoclonal anti-idiotype (anti-Id) antibody, 3H1, which mimics a specific epitope of CEA, for cancer immunotherapy. In this study, the efficacy of 3H1 as a tumor vaccine was(More)
Interleukin-15 (IL-15) has a major role in NK-cell homeostasis. Modulation of the relative frequency and expression intensity of the NK-cell receptors by IL-15 may increase NK cell-mediated cytotoxicity in cancer patients. We investigated the receptor repertoire and measured NK-cell activity in newly diagnosed AML patients and evaluated the ex vivo effects(More)
Carcinomas of the gastrointestinal tract are not curable by standard therapies. Thus, new therapeutic approaches for this disease are needed. This study proposes the use of anti-Id mAb as Ag substitutes to induce anti-tumor immunity in gastrointestinal cancer patients. Recently, we have generated and characterized one monoclonal anti-Id antibody, designated(More)
One-hundred and seven patients with acute myelogenous leukemia (AML) ranging in age from 15 to 82 yr who were previously untreated, received a 70 day high-dose remission induction regimen consisting of daunorubicin, cytarabine, and thioguanine (TAD). Identical complete remission rates of 65% were observed for 33 patients 60 yr of age and older and for 74(More)
PURPOSE We generated an anti-idiotype antibody, designated CeaVac, that is an internal image of the carcinoembryonic antigen (CEA). We previously demonstrated that the majority of patients with advanced colorectal cancer generate specific anti-CEA responses. The purpose of the current study was to treat patients with surgically resected colon cancer with(More)
Over the past ten years, there have been substantial advances in the treatment of AML. Intensive induction chemotherapy using seven-day courses of cytarabine and daunorubicin or amsacrine produce remission in 60-85% of patients. Median remission duration is 9-16 months. In some series, 20-40% of patients are in continuous remission for two years or more;(More)
PURPOSE To determine the antitumor activity of ABX-EGF, a fully human monoclonal antibody to the epidermal growth factor receptor (EGFr), in previously treated patients with metastatic renal cell carcinoma, and to characterize its toxicity, immunogenicity, pharmacokinetics, and pharmacodynamics. PATIENTS AND METHODS The antitumor activity, as well as the(More)
