Randomized Controlled Trial Multicenter Study Clinical Trial
Lumpectomy plus tamoxifen with or without irradiation in women 70 years of age or older with early breast cancer.
In women 70 years of age or older who have early breast cancer, it is unclear whether lumpectomy plus tamoxifen is as effective as lumpectomy followed by tamoxifen plus radiation therapy. ⋯ Lumpectomy plus adjuvant therapy with tamoxifen alone is a realistic choice for the treatment of women 70 years of age or older who have early, estrogen-receptor-positive breast cancer.
