Results using a composite measure of prognostic risk in the BIG 1-98 randomized trial. propranolol and exercise The data show that letrozole, 2.5 mg once daily, is as effective in older, postmenopausal women as it is in younger postmenopausal women with advanced breast cancer. In addition, letrozole was more effective than tamoxifen in both younger and older patients. Presently, 48% of breast cancer cases occur in elderly women (aged 65 years and older) [1], and it is the most common cause of cancer death in women of that age group [2]. Demographic changes in the growing age segment of our population are dramatic: with the aging of the general population, the association between cancer and aging has become more evident and paramount as a pandemic public health concern. As such, formidable increases in the incidence and prevalence of breast cancer can be expected in the coming decades if the older population continues to expand at the present rate [1]. Eighty percent of breast tumors occurring in women aged 70 and older are rich in hormone receptors, while the remaining 20% of women have aggressive tumors that have few hormone receptors [3, 4]. Knowledge of the steroid receptor content of human breast cancer is important for deciding the proper treatment for advanced breast cancer. Endocrine therapy is the established treatment in women with hormone-sensitive tumors, as manifested by positive receptor status, a long disease-free interval, and primarily soft tissue disease.

None of the three aromatase inhibitors was superior to the others in terms of efficacy. Therefore, patient preference, tolerability, and financial constraints should be considered when deciding the optimal. J Egypt Natl Canc Inst. 2010 Mar;22179-85. Switching to letrozole versus continued tamoxifen therapy in treatment of postmenopausal women with early.

    ATLANTA—Postmenopausal women with breast cancer who switch from tamoxifen (Nolvadex) to letrozole (Femara) have a dramatically reduced risk of recurrence and distant metastasis, and they live longer, as evidenced by new data presented at the American Society of Clinical Oncology annual meeting. An updated analysis of the landmark MA-17 trial showed that extended adjuvant use of letrozole, even after years without anticancer therapy, provided significant benefit for 2 populations at high risk of recurrence-women whose cancer has already spread to the lymph nodes at diagnosis (node positive), and women who received chemotherapy after surgery. In this phase 3, double-blind, multicenter trial, 5187 postmenopausal women with early breast cancer who were free of disease after 5 years of tamoxifen therapy were randomly assigned to receive 5 years of letrozole treatment or placebo. The trial was unblinded when the first interim analysis in 2003 showed letrozole lowered the risk of recurrence by 42% compared with placebo. Of the 2268 participants originally assigned to placebo who were then offered letrozole, 1655 women elected to switch to letrozole, while 613 chose not to pursue further treatment. Women who used letrozole for 5 years after tamoxifen significantly improved in all end points. After blinding, a numerical (but not significant) trend was seen toward more clinical fractures in the letrozole-treated patients compared with placebo recipients. Many postmenopausal women take hormonal therapy medicine – either an aromatase inhibitor or tamoxifen – after breast cancer surgery and other treatments for hormone-receptor-positive, early-stage breast cancer. Hormonal therapy medicine can reduce the risk of the cancer coming back (recurrence). A new analysis of results from the BIG 1-98 trial found that the aromatase inhibitor Femara (chemical name: letrozole) improved both disease-free survival (living without the cancer growing) and overall survival (living whether or not the cancer grew) compared to tamoxifen in postmenopausal women diagnosed with estrogen-receptor-positive, HER2-negative breast cancer. The benefits of Femara over tamoxifen were most notable in treating lobular breast cancer compared to ductal breast cancer. Femara was also better at treating luminal B breast cancers with a high level of the protein Ki-67, which helps breast cancer cells grow. The study, "Relative effectiveness of letrozole compared with tamoxifen for patients with lobular carcinoma in the BIG 1-98 trial," was presented at the 2012 San Antonio Breast Cancer Symposium. Lobular breast cancer is breast cancer that begins in the milk-producing lobules, which empty out into the milk ducts that carry milk to the nipple.

Letrozole Sandoz innehåller en aktiv substans som heter letrozol. Det tillhör en grupp av läkemedel som kallas aromatashämmare. Metabolism of letrozole is partly mediated via CYP2A6 and CYP3A4. Cimetidine, a weak, unspecific inhibitor of CYP450 enzymes, did not affect the plasma concentrations of letrozole.
