Bevacizumab found to improve survival for patients with advanced breast cancer

Inhibiting the growth of blood vessels that supply tumors slows the progression of metastatic breast cancer according to results of a large clinical trial of Avastin, an anti-angiogenic therapy.

Cancer stem cells may be at the root of brain tumors

Stem cells -- popularly known as a source of biological rejuvenation -- may play harmful roles in the body, specifically in the growth and spread of cancer. Amongst the wildly dividing cells of a tumor, scientists have located cancer stem cells.

Advanced melanoma - new treatment

University of Illinois at Chicago researchers are participating in a multi-center research trial to evaluate the safety and effectiveness of Allovectin-7, an investigational treatment for advanced melanoma.

Researchers train the immune system to deliver virus that destroys cancer in lab models

An international team of researchers led by Mayo Clinic have designed a technique that uses the body's own cells and a virus to destroy cancer cells that spread from primary tumors to other parts of the body through the lymphatic system.

Plant constituent with selective effect on cancer cells

The substance wogonin triggers the death program apoptosis in tumor cells, while it has virtually no effect on healthy cells.

Scientists identify and repress breast cancer stem cells in mouse tissue

By manipulating highly specific gene-regulating molecules called microRNAs, scientists at Cold Spring Harbor Laboratory (CSHL) report that they have succeeded in singling out and repressing stem-like cells in mouse breast tissue - cells that are widely thought to give rise to cancer.

Agent orange chemical, dioxin, attacks the mitochondria to cause cancer

Researchers with the University of Pennsylvania School of Veterinary Medicine have demonstrated the process by which the cancer-causing chemical dioxin attacks the cellular machinery, disrupts normal cellular function and ultimately promotes tumor progression.

Survival shortened when estrogen or progesterone receptor negative breast cancer spreads to the brain

Two studies from Mayo Clinic's site in Jacksonville, Fla., of women whose breast cancer spread to their brain, have found that women whose tumors do not have estrogen or progesterone receptors have the worst overall outcomes.

Herceptin helps women with multiple chromosomes containing HER2 gene

The targeted therapy Herceptin helps women with HER2+ type of breast cancer independent of whether patients have extra copies of chromosome 17, home to the HER2 gene which produces the HER2 protein that fuels cancer growth.

Tumors less than 1 centimeter in size can be aggressive and may require maximum therapy

Breast tumors that are 1 centimeter in size or smaller - no more than 0.4 inch in length - can still be very aggressive and may require more intensive therapy than is routinely offered today, say researchers at Mayo Clinic in Jacksonville, Fla.

Avastin shows promise for brain cancer

A clinical study conducted at Henry Ford Hospital on the use of a drug to extend the survival of patients with the most common and aggressive type of brain cancer, has yielded results that were significantly better than expected.

Sunitinib may be associated with cardiac toxicity

Another FDA-approved targeted cancer drug, sunitinib (SutentTM, Pfizer), may be associated with cardiac toxicity, report researchers at Children's Hospital Boston, Dana-Farber Cancer Institute (Boston), and Thomas Jefferson University (Philadelphia).

Researchers zero in on the tiniest members in the war on cancer

Researchers from the University of Pennsylvania and Johns Hopkins University have uncovered another reason why one of the most commonly activated proteins in cancer is so dangerous.

New study suggests why vaccines directed against cancer, HIV don't work

Researchers from the University of Missouri and Imperial College London have found evidence suggesting why vaccines directed against the virus that causes AIDS and many cancers do not work.
