    Tamoxifen versus femara


    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. 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.

    Re Side effects of Tamoxifen compared to Letrozole Good luck with whatever decision you,this is a great forum, lots of advice and support from people who understand. 0 Hugs Die beiden Studien untersuchten die Relevanz einer ovariellen Suppression mit AI versus Tamoxifen. Die Therapie mit Exemestan senkte das Rückfallrisiko. Women who received letrozole alone also had better overall survival at 8 years than women receiving tamoxifen alone 83.4 versus 81.2 percent. The differences between the groups were slightly greater in the analysis accounting for the crossover.

    Das Antiöstrogen Tamoxifen (NOLVADEX u.a.) senkt bei Frauen vor und nach den Wechseljahren Rückfallrate und Sterblichkeit bei lokalisiertem Brustkrebs mit positivem oder unbekanntem Hormonrezeptorstatus.1 Die Rezidivrate nach Abschluss der adjuvanten Therapie ist mit jährlich 2% bis 3%2 dennoch beträchtlich. Die durch fünfjährige Tamoxifeneinnahme erzielte Wirksamkeit lässt sich aber offensichtlich nicht weiter steigern. Nach derzeitigem Kenntnisstand bringt eine Verlängerung keinen zusätzlichen Nutzen, sondern scheint sogar zu schaden, möglicherweise wegen Entwicklung einer Abhängigkeit des Tumors von den partiellen östrogen-agonistischen Effekten des Mittels (a-t 1996; Nr. In mehreren randomisierten kontrollierten Studien wird inzwischen geprüft, ob eine Anschlusstherapie mit Aromatasehemmern wie Anastrozol (ARIMIDEX) oder Letrozol (FEMARA) die Rezidivrate und Sterblichkeit weiter senken kann.3 Aromatasehemmer blockieren in peripheren Geweben die Umwandlung von Androgenen in Östrogene und damit den Hauptweg der Östrogensynthese nach den Wechseljahren. Vor der Menopause sind Aromatasehemmer allein unwirksam. Sie sind bisher nur bei fortgeschrittenem Brustkrebs zugelassen, Anastrozol auch zur adjuvanten Behandlung, wenn Tamoxifen kontraindiziert ist. In einem noch nicht abgeschlossenen direkten Vergleich von Anastrozol mit Tamoxifen als primäre adjuvante Therapie nimmt nach einer Zwischenauswertung die krankheitsfreie Überlebenszeit unter Anastrozol zu, ein Vorteil im Hinblick auf die Gesamtsterblichkeit ist aber nicht belegt (a-t 2002; 33: 93-4). Eine Studie zur adjuvanten Anschlusstherapie mit Letrozol wird jetzt aufgrund der ersten Zwischenanalyse nach im Median 2,4 Jahren vorzeitig abgebrochen. uses cookies to improve performance by remembering your session ID when you navigate from page to page.
