Anti-estrogen medication reduces risk of dying from lung cancer

24.01.2011
A new study has found that tamoxifen, an anti-estrogen breast cancer medication, may reduce an individual's risk of death from lung cancer.

Published early online in Cancer, a peer-reviewed journal of the American Cancer Society, the study supports the hypothesis that there is a hormonal influence on lung cancer and that estrogen levels play a role in lung cancer patients' prognosis.

Previous research suggests that menopausal hormone therapy increases women's risk of dying from lung cancer. If this is true, the use of anti-estrogens should have the opposite effect. Elisabetta Rapiti, MD, of the Geneva Cancer Registry led a study that compared lung cancer incidence and mortality among breast cancer patients who were and were not treated with anti-estrogen therapy.

The study included all 6,655 women diagnosed with breast cancer between 1980 and 2003 and registered at the Geneva Cancer Registry. Among these women, 46 percent (3,066) received anti-estrogens. All women were followed for occurrence and death from lung cancer until December 2007.

The investigators found that 40 women in the study developed lung cancer. Incidences of lung cancer was not significantly different between breast cancer patients who were and were not treated with anti-estrogens compared with the general population; however, fewer women taking anti-estrogens died from lung cancer than expected. Specifically, there were 87 percent fewer cases of death due to lung cancer in the anti-estrogen group than in the general population.

"Our results support the hypothesis that there is a hormonal influence on lung cancer which has been suggested by findings such as the presence of estrogen and progesterone receptors in a substantial proportion of lung cancers," said Dr. Rapiti. "If prospective studies confirm our results and find that anti-estrogen agents improve lung cancer outcomes, this could have substantial implications for clinical practice," she added.

Im Focus: It’s All in the Mix: Jülich Researchers are Developing Fast-Charging Solid-State Batteries

There are currently great hopes for solid-state batteries. They contain no liquid parts that could leak or catch fire. For this reason, they do not require cooling and are considered to be much safer, more reliable, and longer lasting than traditional lithium-ion batteries. Jülich scientists have now introduced a new concept that allows currents up to ten times greater during charging and discharging than previously described in the literature. The improvement was achieved by a “clever” choice of materials with a focus on consistently good compatibility. All components were made from phosphate compounds, which are well matched both chemically and mechanically.

The low current is considered one of the biggest hurdles in the development of solid-state batteries. It is the reason why the batteries take a relatively long...
