Researchers have found a new way of halting the growth of breast cancer cells. The researchers explored a new way to starve cancer cells from their molecular energy source. They hope that their discoveries can be further developed into a new way of treating breast cancer, and possibly other types of cancer.
|'Breakthrough' breast cancer drug thwarted by chemical found in bread|

A chemical found in bread and a range of other common foods can thwart treatment for breast cancer, scientists have warned. New research suggested the benefits of the “breakthrough” new drug palbociclib, which is given to women with oestrogen receptor-positive breast cancer, was effectively reversed by xenoestrogens. The compounds are present in products made from wheat, maize, barley and other staples. Scientists said women currently taking the drug should consider altering their diet. They also suggested that, as well as hindering the benefit of the palbociclib, xenoestrogens may accelerate the growth of oestrogen-fuelled cancers themselves. Manufactured by Pfizer, the medication was approved for use on the NHS in November for women with oestrogen receptor-positive breast cancer - which accounts for about 70 per cent of cases - in whom the disease was advanced and unlikely to be cured. The National Institute for Health and Care Excellence gave the green light after trials showed palbociclib could double the period progression-free survival in some patients. Palbociclib was described as the 'next best thing to a cure' Credit: PA Currently available to up to 8,000 women in the UK, it has been described as the “closest thing to a cure”, although scientists have hinted the drug may one day be improved to form a replacement to chemotherapy for women with early-stage breast cancer. However, the new laboratory research by The Scripps Research Institute in California showed that even limited exposure to xenoestrogens largely reversed the impact of the medication when used in combination with letrozole. "It's intriguing that even a low, background-level exposure to these xenoestrogens was enough to impact the effect of the therapy to this degree," said Dr Benedikt Warth, lead author of the study, which is published in the journal Cell Chemical Biology. His colleague, Dr Gary Siuzdak, said: “Breast cancer patients taking palbociclib/letrozole should consider limiting their exposure to foods that contain xenoestrogens." The Scripps team warned they had only tested the effect of two types of xenoestrogens and that many more were to be found in the human diet. “There are probably a lot of clinically relevant discoveries yet to be made,” said Dr Warth.

The Food and Drug Administration on Friday cleared the first treatment for patients with advanced breast cancer caused by BRCA mutations, which are genetic defects that raise the risk of malignancies.
The drug, called Lynparza, already is approved for certain patients with advanced ovarian cancer...
