Abstract

OBJECTIVE: To evaluate the effect of levonorgestrel releasing intrauterine device on endometrium in postmenopausal women with breast cancer on tamoxifen therapy. Design: A prospective randomised controlled study Setting: Sisli Etfal Training and Research Hospital, Second Gynecology and Obstetrics Clinic, Istanbul Patients: Thirty-four asymptomatic postmenopausal women, with uteruses, operated for breast cancer, on tamoxifen therapy for at least one year. Interventions: Levonorgestrel intrauterine systems were applied to 17 subjects (study group). Main outcome measures: At 1. 3. 6. and 12. months of study, endometrial thickness and anteroposterior diameter of uterus was measured, and vaginal bleeding was scored as 0,1,2 and 3 when bleeding was respectively as &#8216;spotting, minimal, mild or heavy&#8217;. Endometrial biopsies were repeated at the end. RESULTS: There was no difference between the groups with regard to age, gravity, parity, plasma hormone levels, duration of menopause, time passed till diagnosis of breast cancer and duration of tamoxifen use (p>0.05). For all time intervals, there was no difference in the anteroposterior diameter of uterus and endometrial thickness between the groups. However, in the study group, there was a significant decrease in anteroposterior diameter between 1. and 12. months of study (p<0.05) and a meaningful decline in endometrial thickness beginning from the third month (p<0.001). Vaginal bleeding declined significantly (p<0.0001). At the end of one year, the endometrial biopsies in the study group revealed 100% decidual reaction. CONCLUSION: Levonorgestrel intrauterine system is a new preventive measure against undesirable agonistic effects of tamoxifen on endometrium.

Özet

AMAÇ: Tamoksifen alan meme kanserli postmenopozal kadınlarda levonorgestrel intrauterin sistemin endometriyum üzerine etkisinin incelenmesi. Planlama: Prospektif randomize kontrollü çalışma. Ortam: Şisli Etfal Eğitim ve Araştırma Hastanesi 2. Kadın Hastalıkları ve Doğum Kliniği, İstanbul. Hastalar: Otuzdört asemptomatik postmenopozal, meme kanseri nedeniyle opere olmuş, en az bir yıldır tamoksifen tedavisi alan, uterusları olan hastalar. Girişim: : Levonorgestrel intrauterin sistem 17 olguya uygulandı (çalışma grubu). Değerlendirme parametreleri: Çalışmanın 1. 3. 6. ve 12. aylarında, endometriyal kalınlık ve uterus ön-arka çapı ölçüldü ve vaginal kanama miktarı ‘lekelenme, minimal, orta veya ağır’ olacak şekilde sırasıyla 0,1,2 ve 3 olarak skorlandı. Çalışma sonunda endometriyal biyopsiler tekrarlandı. SONUÇ: Çalışma ve kontrol grubu arasında yaş, gravida, parite, plazma hormon düzeyleri, menopoz süresi, meme kanser tanısından sonra geçen süre ve tamoksifen tedavi süresi açısından fark yoktu (p>0.05). İncelenen tüm zaman dilimlerinde, gruplar arasında uterus ön-arka çapı ve endometriyal kalınlık farkı yoktu. Ancak, çalışma grubunda, 1. ve 12. aylar arası uterus ön-arka çapında anlamlı bir azalma oldu (p<0.05) ve 3. aydan başlayarak endometriyal kalınlıkta anlamlı bir incelme gözlendi (p<0.001). Vaginal kanama anlamlı derecede azaldı (p<0.0001). Bir yılın sonunda, çalışma grubundaki endometriyal biopsilerde %100 desidual reaksiyon izlendi. YORUM: Levonorgestrel intrauterin sistem, tamoksifen tedavisinin endometriyum üzerindeki istenmeyen etkilerini önlemede yeni ve etkili bir yöntemdir.
