Most Women with Early Breast Cancer Do Not Benefit From Chemotherapy

Most girls with the most Frequent kind of early-stage Breast cancer may safely bypass chemotherapy without damaging their chances of beating the illness, physicians are reporting from a landmark study that used genetic testing to evaluate every individual's risk.

Around half of women taking aromatase inhibitors, a common drug for postmenopausal women with hormone receptor positive breast cancer, experience joint pain.

Of those, 6711 scored in the intermediate range of 11-25, and were randomly assigned hormone therapy alone or hormone therapy plus chemotherapy.

Certain girls 50 or younger did gain from chemo; marginally fewer Instances of cancer spreading far beyond the breast happened among a number of them awarded chemo, based upon their threat scores on the gene evaluation.

"Until now, we've been able to recommend treatment for women with these cancers at high and low risk of recurrence, but women at intermediate risk have been uncertain about the appropriate strategy to take", said Jeffrey Abrams, M.D., associate director of NCI's Cancer Therapy Evaluation Program. "We know that we can use this data and tell women firmly, 'You don't need chemotherapy; you're going to do so well without it'".

After nine Decades, 94 percent of both teams were still living, and About 84 percent were living with no signs of cancer, therefore adding chemo made no real difference. The study confirmed that using a 21-gene analyzation to assess cancer recurrence risk can successfully indicate whether or not a woman needs to undergo invasive and unnecessary chemotherapy treatment. This finding indicates the need to develop more effective therapies for women at high risk of recurrence.

The results of the trial suggest that up to 85 percent of women with early breast cancer can be spared chemotherapy - especially those over 50 years of age.

There is one caveat to the new findings. "The trial was created to address this question and provides a very definitive answer", said Dr. Sparano.

Dr. Chang, who leads part of Cancer Research UK's Precision Panc trial, said many different treatment combinations for pancreatic cancer are now emerging and further work is needed to see which may benefit patients most before surgery. Typically, it is performed on tumors that are in the early stages. Without the stamp money, the study may never have been done, he said. It was first issued in 1998 and has been reissued multiple times since, and has raised more than $86 million for breast cancer research.

The genomic assay used in the trial was the Oncotype DX Breast Recurrence Score test from Genomic Health, Inc., Redwood City, California.
