Turning viruses into allies against cancer

...s to other parts of the body. "This aims to treat metastatic disease and reduce tumor recurrence," said Robert Coffin, Ph.D., chief scientific officer at Biovex Ltd. While this has not been demonstrated in patients, the approach has show promise in pre-clinical studies. In a phase I/II clinical trial, the sci...

Study reveals dramatic difference between breast cancers in US and Africa

...he drug Herceptin, which was recently approved for metastatic breast cancer. It is over-expressed in about 23 percent of Caucasians and 19 percent of Africans. Breast cancer strikes fewer women in Africa, "but it hits earlier and harder," said Olopade. In America, most breast cancer occurs after menopause, usu...

Unchecked DNA replication drives earliest steps toward cancer

...s or tumor suppressor genes. Full-blown tumors and metastatic cancers, however, often exhibit many genetic mutations, sometimes dozens in a given tumor. An important scientific question, and one with significant clinical implications, has been what happens after the initial mutation that leads to dangerous late...

Characterizing Skin Cancer by Microarrays

...ng in increased risk of metastasis. However, some metastatic tumors retained a gene expression pattern characteristic of the radial growth phase, which implies that both radial and vertical melanomas can metastasize. The authors identified over 2,000 genes that distinguished the stages of melanoma progression....

NCI Researchers Confirm the Effectiveness of Immunotherapy Approach to Treating Melanoma

...timulated, white blood cells can have an impact on metastatic melanoma tumors in patients who do not respond to other therapies. "The results of this study are encouraging, and suggest that some patients with melanoma who do not respond to conventional treatments may get a durable benefit from treatments based ...

New understanding of cell movement may yield ways to brake cancer's spread

Scientists turn tobacco against cancer

...rectal cancer cells and have been used in treating metastatic disease and in preventing recurrence in certain high-risk patients. But the technology to produce large amounts of antibody is expensive, and researchers would like to find alternatives. Dr. Koprowski, Dr. Ko and their co-workers had previously shown...

Treatments have same target, different responses for lung cancer patients with genetic mutation

... cetuximab, which is approved for the treatment of metastatic colorectal cancers that overexpress EGFR. Cetuximab targets EGFR by preventing its activation by extracellular signals, or signals occurring outside of the cell, as opposed to the intra-cellular signal blocking of drugs like gefitinib. The researc...

Columbia scientists develop cancer terminator viruses

... an anti-tumor immune response against the distant metastatic cancer cells. In the PNAS paper, Dr. Fisher and the team describe the production of a virus conceptually similar to the "terminator" virus, which selectively replicates and kills breast cancer cells in mice. Human breast tumor xenografts were estab...

Vaccine targets tumors where they live

...being designed to battle cancer, but their use for metastatic melanoma is a challenge. Effective vaccines against established tumors require tumor-reactive T cells to traffic to the sites of the tumors and are locally activated there in order to kill cancer cells. A problem is that the T cells lose their tumor-...

The Listeria vector is currently being prepared for a clinical trial targeting a tumor antigen associated with cervical cancer by Advaxis Inc., a cancer vaccine biotech company that has licensed Penn patents on ...

Optimizing cell therapy against tumors is a balancing ACT

...nsfer (ACT) therapy is used to treat patients with metastatic solid tumors. ACT involves the removal of some of the patient's cancer cells, and some of their immune T cells. When the cells are mixed together, specific parts of the cancer cells that stimulate the T cells to cause an immune attack can be identifi...

Eleven gene 'signature' reliably predicts cancer prognosis
