A total of 184 patients started extended adjuvant therapy with Femara (172patients) or with another aromatase inhibitor (12 patients). To explore the impact of this selective crossover, results fromanalyses censoring follow-up at the date of the selective crossover (in the tamoxifen arm) are presented for the MAA. For first-line treatment of most premenopausal women, ASCO recommends combination therapy with a nonsteroidal aromatase inhibitor (e.g., letrozole, anastrozole) and a CDK 4/6 inhibitor, in conjunction with chemical ovarian function suppression.

In total, 41% of patients were aged 65 years or older at enrollment, while 12% were 75 or older.

Median progression free survival was beyond 19.3 months and no patients discontinued therapy due to toxicities. Cholesterol levels should be monitored and some patients may require treatment for high cholesterol levels.
