Roche Inc. announced on Monday that Herceptin extended the lives of women with advanced HER2-positive breast cancer when it was used in conjunction with the hormone therapy known as Arimidex.
"Patients who received Herceptin had a statistically significant improvement in progression-free survival," the Swiss drug maker said in a statement.

HER2-positive breast cancer is a particularly aggressive form of hormone receptor-positive breast cancer; the prognosis for these patients is typically bleak. Hormone receptor-positive breast cancers account for two-thirds of all cases worldwide, and roughly a quarter of these cases are also HER2-positive. Roche noted that this was the first randomised trial to look at how Herceptin works in this subset of breast cancer patients.
According to the company statement, Herceptin is currently only licensed to treat metastatic cancer - where tumours have spread throughout the body - in the European Union. On the 24th of May 2006 the EU granted approval in Europe for early use of Herceptin in HER2-positive breast cancer.
To date, more than 230 000 breast cancer patients have been treated with Herceptin worldwide, according to the company statement. (HealthDayNews)
