    ABSTRACT: In a RCT, we have previously shown that the levonorgestrel intrauterine system (LNG-IUS, Mirena) produces a decidual response protecting the endometrium at one year follow-up. We here report on the long-term follow-up of this group of women, to test the hypothesis that a LNG-IUS could prevent the pro-proliferative uterine responses of tamoxifen for up to 4.5 years. A randomised-controlled trial of postmenopausal women who had taken at least one year of adjuvant tamoxifen therapy. One hundred twenty-two women were recruited. Nine were found to be ineligible after randomisation. The average duration of follow-up was 26.25 months (IQR 14.5-36 months) in the surveillance group and 24.2 months (IQR 13.75-32.5 months) in the LNG-IUS group. Women with LNG-IUS in situ at the time of final assessment had decidualised endometrium, and no polyps. In the surveillance group new polyps arose in 8 cases. There were 3 new polyps in the group initially randomised to LNG-IUS, one in a patient who did not have the device inserted and 2 occurred in patients following the removal of the LNG-IUS. Univariate Cox proportional hazards regression models identified only endometrial thickness at trial entry as a statistically significant variable (HR 1.12, 95% CI 1.02 to 1.22, p=0.01) for the development of polyps. This study confirms that LNG-IUS induces benign endometrial changes and prevents endometrial polyps but only during its use in women taking tamoxifen. Endometrial thickness is a risk factor for the development of polyps.

    ABSTRACT: Tamoxifen is currently the most commonly used adjuvant treatment for breast cancer, however, it frequently causes episodes of unscheduled uterine bleeding, which could be associated with proliferative changes of the endometrium, or even endometrial cancer. We aimed to assess whether a levonorgestrel intrauterine system could modulate the uterine responses to tamoxifen. We also aimed to assess women's tolerance of the screening procedures, the insertion, removal, and potential side-effects of the device. We did a randomised controlled trial, in which postmenopausal women who had had at least 1 year of adjuvant tamoxifen treatment and who were undergoing regular follow-up for breast cancer were randomly assigned to either endometrial surveillance alone, or endometrial surveillance before and after insertion of the levonorgestrel intrauterine system for 12 months. We assessed tolerance of the surveillance procedures and the device with visual analogue scales. Baseline assessment showed only benign uterine changes in all women (n=122). Hysteroscopic assessment indicated a uniform decidual response (confirmed histologically in 40 of 41 cases) in all women fitted with the intrauterine system; there were no new polyps in these women and 13% had fewer fibroids than in controls. Both screening procedures and device were well tolerated. There was an excess of bleeding in the women fitted with intrauterine systems but this resolved to a baseline similar to those receiving surveillance only. The levonorgestrel-releasing intrauterine system had a protective action against the uterine effects of tamoxifen. The effectiveness of this device in preventing uterine changes in the endometrium needs to be assessed in the context of decreasing the need for repeated investigations of postmenopausal bleeding in women taking tamoxifen.

    ABSTRACT: The aim of this study was to assess the ability of transvaginal sonography (TVS) and office hysteroscopy with sharp curettage to characterize the morphological changes in the uteri of asymptomatic postmenopausal women taking long-term tamoxifen for breast cancer. The overall acceptability of a single-visit screening clinic for these women was also evaluated. Fifty-eight women were recruited from patients undergoing regular follow-up at the Leicester Royal Infirmary for breast cancer. A single-visit clinic was acceptable to 94.8% of these women. Transvaginal sonography detected endometrial thickness of greater than 5 mm in 84.5% of cases, but there was no relationship between total tamoxifen exposure and endometrial thickness. Transvaginal sonography also detected uterine lesions such as fibroids and endometrial cysts in 34.5% of cases. Hysteroscopy detected the latter uterine lesions in 53.4% of cases, with three cases (5.2%) of endometrial polyps also being identified in these women. Sharp curettage sampling of the endometrium produced specimens sufficient for diagnosis in 84.5% of cases; 70.7% of specimens were reported as showing types of 'quiescent' endometrium with 13.8% of specimens showing 'active' endometrium. In the latter group, there was a case of complex hyperplasia detected and also a case with granulomatous endometritis. For each histopathological diagnosis identified, there was a wide range of endometrial thickness recorded by TVS. A single-visit screening clinic involving TVS and hysteroscopy with sharp curettage was acceptable to asymptomatic women taking tamoxifen. However, hysteroscopy was more effective than TVS in detecting endometrial lesions such as polyps, fibroids and cystic areas. Although TVS detected endometrial thickness greater than 5 mm in the majority of cases, there were no malignancies detected and, for each histopathological classification, there was a wide range of endometrial thickness associated. Thus, the isolated use of TVS is insufficient for screening the endometria of these women.
