The aim of this study is to evaluate the accuracy of hysteroscopy in detecting tamoxifen-associated endometrial morbidity. Ninety-eight menopausal breast cancer patients taking tamoxifen underwent hysteroscopy because of an endometrial thickness above 4mm measured by Transvaginal Ultrasonography. Thirty-one women recorded uterine bleeding while 67 were asymptomatic. Hysteroscopies with operative facilities were performed, mainly in out-patient setting. Hysteroscopic findings were matched with histopathology derived from various modalities of tissue collection as suction-curettage, oriented-streak curettage, hysteroscopically-targeted biopsies or polypectomies and hysterectomies. Accuracy of hysteroscopy to estimate a normal or abnormal endometrium was calculated. Abnormal endometrium was detected in 35 patients (64.5% in symptomatic and 22.3% in asymptomatic women, P < 0.001). We found six carcinomas, 18 polyps and 11 hyperplasias. Hysteroscopy showed sensitivity and specificity of 89.2 and 98.4%, respectively. By blind sampling, tissue collection was too scant to give a diagnosis in 29. 1% of patients and in 80.5% of patients in whom hysteroscopy showed cystic atrophy the pathologist failed to confirm this condition. Moreover, eight endometrial polyps (36.3%) detected by hysteroscopy were missed. Conversely, by tissue sampling under vision no inadequate specimen was sent to the pathologist and all hysteroscopies showing cystic atrophy and polyps were pathologically confirmed. From literature data, the detection-rate of endometrial pathology in tamoxifen users varies from the lowest to the highest prevalences whether blind or hysteroscopically-targeted modalities of tissue sampling were used, respectively. Hysteroscopy with targeted sampling appears to be the most effective method to assess the endometrial lining. In our experience it is safe, well tolerated and it should be considered the reference test to assess a thickened endometrium in women under tamoxifen.
