title: [Aromatase inhibitors of the 3rd generation. What can the "pill against breast cancer" really do?].
abstract: Metastatic cancer of the breast in postmenopausal women can be treated with a number of "hormone-active" substances. The drugs of first choice are still anti-estrogens. Today, the three highly selective oral aromatase inhibitors anastrozole, letrozole and exemestane are additionally available for use in continuing progression under anti-estrogen treatment. Roughly one woman in three derives benefit from these new medications as reflected by objective remission or stabilization of the disease for more than 6 months. Neither chemical structure (steroidal/non-steroidal), nor the different nature of inhibition of the active centre of the aromatase, nor whether the inhibition of the enzyme is reversible or irreversible, has any influence on the parameters: response rate, response duration and clinical benefit.
