Breast Cancer Treatment (PDQ®): Treatment - Health Professional Information [NCI] - General Information About Breast Cancer


Two randomized trials (including Regional Oncologic Center-Hormonal Replacement Therapy After Breast Cancer--Is It Safe [ROC-HABITS]) comparing HRT with no hormonal supplementation have been reported.[36,37] The first trial included 345 evaluable breast cancer patients with menopausal symptoms and was terminated early because of an increased incidence of recurrences and new primaries in the HRT group (hazard ratio [HR], 3.5; 95% confidence interval [CI], 1.5–7.4).[36][Level of evidence: 1iiDii] In total, 26 women in the HRT group and 7 in the non-HRT group developed recurrences or new primaries. This study, however, was not double blinded, and it is possible that patients on HRT were monitored more closely. Because of the results of the first trial, the second trial, which was conducted under a joint steering committee with the first, closed prematurely after the enrollment of 378 patients.[37] With a median follow-up of 4.1 years, there were 11 recurrences in the hormone replacement group and 13 recurrences in the patients assigned to no hormone replacement (HR, 0.82; 95% CI, 0.35–1.9).[37][Level of evidence: 1iiDii] The trials differed in several ways;[38] however, until further data become available, decisions concerning the use of HRT in patients with breast cancer will have to be based on the results of these studies and on inferences from the impact of HRT use on breast cancer risk in other settings.[38] A comprehensive intervention, including education, counseling, and nonhormonal drug therapy, has been shown to reduce menopausal symptoms and to improve sexual functioning in breast cancer survivors.[39][Level of evidence: 1iiC] (Refer to the PDQ summaries on Fever, Sweats, and Hot Flashes and Sexuality and Reproductive Issues for more information.)

Breast Reconstruction

For patients who opt for a total mastectomy, reconstructive surgery may be used at the time of the mastectomy (immediate reconstruction) or at some subsequent time (delayed reconstruction).[40,41,42,43] Breast contour can be restored by the submuscular insertion of an artificial implant (saline-filled) or a rectus muscle or other flap. If a saline implant is used, a tissue expander can be inserted beneath the pectoral muscle. Saline is injected into the expander to stretch the tissues for a period of weeks or months until the desired volume is obtained. The tissue expander is replaced by a permanent implant. (Visit the FDA's Web site for more information on breast implants.) Rectus muscle flaps require a considerably more complicated and prolonged operative procedure, and blood transfusions may be required.

Following breast reconstruction, radiation therapy can be delivered to the chest wall and regional nodes either in the adjuvant setting or if local disease recurs. Radiation therapy following reconstruction with a breast prosthesis may affect cosmesis, and the incidence of capsular fibrosis, pain, or the need for implant removal may be increased.[44]
