Brief summary

Patients are eligible for inclusion in this NIS if they have taken anastrozole either upfront or following two to three years of tamoxifen treatment (switch) for at least three and not more than six months prior to offering an individual participation in this program. Treatment should follow local therapy guidelines and standard practice. Treatment decisions for patients participating in this study including assessments or supportive therapy during follow-up visits will also follow guidelines and remain independent of the program.

Detailed description

The patient population will include postmenopausal women with hormone-receptor positive primary breast cancer scheduled for adjuvant upfront endocrine treatment with anastrozole or following two to three years of tamoxifen treatment (switch) according to the current SmPC (Appendix C). Patients will have taken anastrozole for at least three months and not more than six months before the start of the study.
