Hepatic arterial chemotherapy for primary and metastatic liver cancers

Hepatic arterial chemotherapy represents a means of selectively exposing hepatic tumor to cytotoxic agents. Although 5-fluoro-2′-deoxyuridine has been shown to generate a higher response rate in the treatment of colorectal liver metastases than that achieved by intravenous infusion, responses are largely incomplete and rarely of long duration. This review describes the rationale for the use of the thymidine analogs 5-bromo-2′-deoxyuridine and 5-iodo-2′-deoxyuridine in hepatic arterial infusions and indicates how combination therapy adding radiotherapy, specifically with hepatic arterially administered yttrium-90 microspheres, might generate a new, more efficient and effective therapeutic approach.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/46919/1/280_2004_Article_BF00647244.pd

Activation of T lymphocytes for the adoptive immunotherapy of cancer

Background: Adoptive immunotherapy of malignancy involves the passive transfer of antitumor-reactive cells into a host in order to mediate tumor regression. Based on animal models, the transfer of immune lymphoid cells can eradicate widely disseminated tumors and establish long-term systemic immunity. Critical for successful adoptive immunotherapy is the ability to isolate large numbers of immune cells. For clinical therapy, it will require the development of in vitro methods to promote the sensitization and propagation of tumor-reactive cells. However, this is formidable task since human cancers are postulated to be poorly immunogenic because of their spontaneous origins.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/41399/1/10434_2006_Article_BF02303568.pd
