To the Editor: de-escalating the treatment of ductal carcinoma in situ (dCIS) of the breast has been investigated in recent years. A 5-year adjuvant endocrine therapy (AET) regimen is the recommended treatment for hormone receptor-positive dCIS. Selective estrogen receptor modulators (such as the commonly used tamoxifen and toremifene) and aromatase inhibitors (AIs) are the currently used AET drugs. However, long-term AET is accompanied.b. severe side effects such as menopausal symptoms, endometrial carcinoma, cardiovascular events, venous thromboembolic events, osteoporosis, and joint pain that can significantly reduce patients’ quality of life. It was reported that only 50% of the patients completed the recommended 5-year AET mainly because of side effects, while higher adherence rates were observed with shorter-duration regimens. Therefore, de-escalation of AET should.b. considered to reduce the side effects of AET and improve adherence.
