We analyzed data from women who had ER-positive breast cancer that had been diagnosed before the age of 75 years and who had T1 disease (tumor diameter, ≤2.0 cm) or T2 disease (tumor diameter, >2.0 to 5.0 cm), fewer than 10 involved nodes (stratified according to a pathological nodal status of no nodes [N0], 1 to 3 nodes [N1–3], or 4 to 9 nodes [N4–9]), and no distant metastases. All the patients were scheduled to receive endocrine therapy for 5 years then stop, regardless of actual adherence. Most of the patients entered the study at the time of diagnosis, but some entered later, having already received 2 to 5 years of endocrine therapy, but were scheduled to stop therapy at 5 years.
How long does endocrine therapy last?
The administration of endocrine therapy for 5 years substantially reduces recurrence rates during and after treatment in women with early-stage, estrogen-receptor (ER)–positive breast cancer. Extending such therapy beyond 5 years offers further protection but has additional side effects. Obtaining data on the absolute risk of subsequent distant recurrence if therapy stops at 5 years could help determine whether to extend treatment.
Can you extend tamoxifen for 5 years?
Extending adjuvant endocrine therapy (with either tamoxifen or an aromatase inhibitor) beyond 5 years can further reduce recurrence.4–9For some women, however, receiving endocrine therapy for 5 years causes appreciable side effects, such as menopausal symptoms and arthropathy, which could continue with extended treatment.9–11Much less common, but potentially life-threatening, side effects of adjuvant endocrine therapy include pulmonary embolus and endometrial cancer associated with tamoxifen and osteoporotic fracture associated with aromatase inhibitors, and the cumulative risk of these toxic events increases with longer treatment.2,3,5,6,9

What is the treatment for breast cancer?
After surgery, women diagnosed with early-stage, hormone-receptor-positive breast cancer usually take hormonal therapy medicine to reduce the risk of the cancer coming back (recurrence). Recurrence can be local (the cancer coming back in the breast area), regional (coming back in the chest wall or area near the breast), or distant/metastatic (the cancer coming back in a part of the body away from the breast, such as the bones or liver).
How long does it take for breast cancer to recur?
If doctors knew the specific risk of distant recurrence of a breast cancer after 5 years of hormonal therapy, it could help decide whether to extend hormonal therapy to 10 years. A study suggests that after 5 years of hormonal therapy, the risk of distant recurrence is still sizable, even 20 years after the initial diagnosis.
