PURPOSE As treatment options expand for metastatic colorectal cancer (mCRC), a blood marker with a prognostic and predictive role could guide treatment. We tested the hypothesis that circulating tumor cells (CTCs) could predict clinical outcome in patients with mCRC. PATIENTS AND METHODS In a prospective multicenter study, CTCs were enumerated in the(More)
BACKGROUND We demonstrated that circulating tumor cell (CTC) number at baseline and follow-up is an independent prognostic factor in metastatic colorectal cancer (mCRC). This analysis was undertaken to explore whether patient and treatment characteristics impact the prognostic value of CTCs. PATIENTS AND METHODS CTCs were enumerated with immunomagnetic(More)
The NCCN Soft Tissue Sarcoma Guidelines include a subsection about treatment recommendations for gastrointestinal stromal tumors (GISTs). The standard of practice rapidly changed after the introduction of effective molecularly targeted therapy (such as imatinib and sunitinib) for GIST. Because of these changes, NCCN organized a multidisciplinary panel(More)
BACKGROUND Although commonly used in combination with irinotecan or oxaliplatin (iri/oxal) for treatment of colorectal liver metastases before extirpation, the effects of preoperative bevacizumab on surgical outcomes are not established. The objective of this retrospective study was to determine if addition of bevacizumab to iri/oxal preoperative(More)
BACKGROUND Although established for metastatic colorectal (CR) and neuroendocrine (NE) malignancies, the role of partial hepatectomy in management of metastases from other primaries (NCRNE) is not well-defined. STUDY DESIGN The objective of this retrospective study is to compare outcomes after partial hepatectomy for NCRNE, NE, and CR metastases and to(More)
Following analysis by reversed-phase HPLC, a previously uncharacterized metabolite of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) was found in the urine of A/J mice treated with NNK. Treatment with beta-glucuronidase converted the metabolite to a peak that co-eluted with 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL). Treatment with sulfatase(More)
PURPOSE GVAX pancreas, granulocyte-macrophage colony-stimulating factor-secreting allogeneic pancreatic tumor cells, induces T-cell immunity to cancer antigens, including mesothelin. GVAX is administered with low-dose cyclophosphamide (Cy) to inhibit regulatory T cells. CRS-207, live-attenuated Listeria monocytogenes-expressing mesothelin, induces innate(More)
Our previous studies showed that phenethyl isothiocyanate (PEITC), a cruciferous vegetable constituent, inhibited the lung tumorigenesis induced by a potent tobacco-specific carcinogenic nitrosamine in animals. These results implicate dietary PEITC as a risk-reducing factor of lung cancers induced by smoking. To define the effect of dietary PEITC on human(More)
Laboratory isolates of human immunodeficiency virus type 1 (HIV-1) that utilize CXCR4 as a coreceptor infect primary human macrophages inefficiently even though these express a low but detectable level of cell surface CXCR4. In contrast, infection of primary macrophages by primary CXCR4-tropic HIV-1 isolates is readily detectable. Here, we provide evidence(More)
Immunizations with dendritic cells (DC) transfected with RNA encoding tumor antigens induce potent tumor antigen-specific immune responses in vitro and in murine models. We performed a phase I study of patients with advanced carcinoembryonic antigen (CEA)-expressing malignancies followed by a phase II study of patients with resected hepatic metastases of(More)
