The purpose

Established in 2010, the Long-term Anastrozole vs Tamoxifen Treatment Effects (LATTE) observational study aims to collect vital long-term safety and efficacy data on anastrozole and tamoxifen, drugs that were taken by post-menopausal women as part of the Anastrozole Tamoxifen Alone or in Combination (ATAC) trial. ATAC was a crucial breast cancer trial evaluating the use of aromatase inhibitors (AIs) in the adjuvant setting, with a median follow-up of over 10 years. The ATAC trial assessed the safety and efficacy of anastrozole+placebo, tamoxifen+placebo and anastrozole+tamoxifen in postmenopausal women undergoing treatment for invasive primary breast cancer
