Abstract
BACKGROUND Adjuvant tamoxifen reduces the risk of breast cancer recurrence in women with oestrogen receptor-positive breast cancer. Tamoxifen also increases the risk of postmenopausal bleeding, endometrial polyps, hyperplasia, and endometrial cancer. The levonorgestrel-releasing intrauterine system (LNG-IUS) causes profound endometrial suppression. This systematic review considered the evidence that the LNG-IUS prevents the development of endometrial pathology in women taking tamoxifen as adjuvant endocrine therapy for breast cancer. OBJECTIVES To determine the effectiveness and safety of the levonorgestrel intrauterine system (LNG-IUS) in pre- and postmenopausal women taking adjuvant tamoxifen following breast cancer for the outcomes of endometrial and uterine pathology including abnormal vaginal bleeding or spotting, and secondary breast cancer events. SEARCH METHODS We searched the following databases on 29 June 2020; The Cochrane Gynaecology and Fertility Group specialised register, Cochrane Central Register of Controlled Trials, MEDLINE, Embase, PsycINFO and Cumulative Index to Nursing and Allied Health Literature. We searched the Cochrane Breast Cancer Group specialised register on 4 March 2020. We also searched two trials registers, checked references for relevant trials and contacted study authors and experts in the field to identify additional studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) of women with breast cancer on adjuvant tamoxifen that compared the effectiveness of the LNG-IUS with endometrial surveillance versus endometrial surveillance alone on the incidence of endometrial pathology. DATA COLLECTION AND ANALYSIS We used standard methodological procedures recommended by Cochrane. The primary outcome measure was endometrial pathology (including polyps, endometrial hyperplasia, or endometrial cancer), diagnosed at hysteroscopy or endometrial biopsy. Secondary outcome measures included fibroids, abnormal vaginal bleeding or spotting, breast cancer recurrence, and breast cancer-related deaths. We rated the overall certainty of evidence using GRADE methods. MAIN RESULTS We included four RCTs (543 women analysed) in this review. We judged the certainty of the evidence to be moderate for all of the outcomes, due to imprecision (i.e. limited sample sizes and low event rates). In the included studies, the active treatment arm was the 20 μg/day LNG-IUS plus endometrial surveillance; the control arm was endometrial surveillance alone. In tamoxifen users, the LNG-IUS probably reduces the incidence of endometrial polyps compared to the control group over both a 12-month period (Peto odds ratio (OR) 0.22, 95% confidence interval (CI) 0.08 to 0.64, I² = 0%; 2 RCTs, n = 212; moderate-certainty evidence) and over a long-term follow-up period (24 to 60 months) (Peto OR 0.22, 95% CI 0.13 to 0.39; I² = 0%; 4 RCTs, n = 417; moderate-certainty evidence). For long-term follow-up, this suggests that if the incidence of endometrial polyps following endometrial surveillance alone is assumed to be 23.5%, the incidence following LNG-IUS with endometrial surveillance would be between 3.8% and 10.7%. The LNG-IUS probably slightly reduces the incidence of endometrial hyperplasia compared with controls over a long-term follow-up period (24 to 60 months) (Peto OR 0.13, 95% CI 0.03 to 0.67; I² = 0%; 4 RCTs, n = 417; moderate-certainty evidence). This suggests that if the chance of endometrial hyperplasia following endometrial surveillance alone is assumed to be 2.8%, the chance following LNG-IUS with endometrial surveillance would be between 0.1% and 1.9%. However, it should be noted that there were only six cases of endometrial hyperplasia. There was insufficient evidence to reach a conclusion regarding the incidence of endometrial cancer in tamoxifen users, as no studies reported cases of endometrial cancer. At 12 months of follow-up, the LNG-IUS probably increases abnormal vaginal bleeding or spotting compared to the control group (Peto OR 7.26, 95% CI 3.37 to 15.66; I² = 0%; 3 RCTs, n = 376; moderate-certainty evidence). This suggests that if the chance of abnormal vaginal bleeding or spotting following endometrial surveillance alone is assumed to be 1.7%, the chance following LNG-IUS with endometrial surveillance would be between 5.6% and 21.5%. By 24 months of follow-up, abnormal vaginal bleeding or spotting occurs less frequently than at 12 months of follow-up, but is still more common in the LNG-IUS group than the control group (Peto OR 2.72, 95% CI 1.04 to 7.10; I² = 0%; 2 RCTs, n = 233; moderate-certainty evidence). This suggests that if the chance of abnormal vaginal bleeding or spotting following endometrial surveillance alone is assumed to be 4.2%, the chance following LNG-IUS with endometrial surveillance would be between 4.4% and 23.9%. By 60 months of follow-up, there were no cases of abnormal vaginal bleeding or spotting in either group. The numbers of events for the following outcomes were low: fibroids (n = 13), breast cancer recurrence (n = 18), and breast cancer-related deaths (n = 16). As a result, there is probably little or no difference in these outcomes between the LNG-IUS treatment group and the control group. AUTHORS' CONCLUSIONS: The LNG-IUS probably slightly reduces the incidence of benign endometrial polyps and endometrial hyperplasia in women with breast cancer taking tamoxifen. At 12 and 24 months of follow-up, the LNG-IUS probably increases abnormal vaginal bleeding or spotting among women in the treatment group compared to those in the control. Data were lacking on whether the LNG-IUS prevents endometrial cancer in these women. There is no clear evidence from the available RCTs that the LNG-IUS affects the risk of breast cancer recurrence or breast cancer-related deaths. Larger studies are necessary to assess the effects of the LNG-IUS on the incidence of endometrial cancer, and to determine whether the LNG-IUS might have an impact on the risk of secondary breast cancer events.

Abstract
The levonorgestrel-releasing intrauterine system (LNG-IUS) is widely used and recommended as a reliable contraceptive. It also acts by opposing the effects of estrogen on the endometrium, thereby preventing development of endometrial hyperplasia and its possible malignant transformation. This case describes a 52-year-old multiparous amenorrhoeic patient who was seen in the gynecology outpatient department for a routine control 46 months after the insertion LNG-IUS as contraception. Hysteroscopy with a target biopsy following suspicious ultrasound scan confirmed well-differentiated endometrioid adenocarcinoma. Ultrasound scan prior to inserting LNG-IUS revealed normal 5 mm thin endometrium with the sharp edges. Uterine bleeding before the LNG-IUS insertion was regular and not excessive and the woman has remained amenorrhoeic after the LNG-IUS insertion. We present a case of the growth of a polyp-shaped endometrial carcinoma in a LNG-IUS asymptomatic user.

Abstract
OBJECTIVES The study was designed to assess user satisfaction and duration of use of intrauterine contraceptive device (IUD) in Fife. METHODS A questionnaire was given to 254 women attending a Fife Family Planning Clinic, in whom an IUD had been fitted over 3 years ago, with a 71% response rate. RESULTS The majority of respondents were over age 30 years (81%) and parous (91%). The most frequently used IUD was the levonorgestrel-releasing intrauterine system (LNG-IUS: 39%), with the rest of the coils being an assortment of copper-medicated coils. Side effects were common, occurring in 92% of users and compliance was low, with 23% using for less than 1 year. Comparisons between LNG-IUS and other IUD-users showed similar side-effects, although mood disorders were higher with LNG-IUS. CONCLUSIONS Overall satisfaction rates with the family planning service were high. Methods to improve IUD uptake and compliance are needed, particularly in younger women and nulliparous women.

Abstract
This study outlines the histologic changes seen in 106 endometrial specimens after use of the Mirena coil (levonorgestrel) and compares these changes with previous studies. The variables assessed include nature of the endometrial glands, metaplastic glandular changes, nuclear atypia, hobnail change, and endometrial hyperplasia. Stromal changes include pseudodecidualization, mucinous change, ulceration, and infiltration by granulocytes, neutrophils, and plasma cells, and stromal hyaline nodules, a feature not described previously. Additional changes include superficial micropapillary change, infarcted decidua, dystrophic calcification, hemosiderophages, polypoid indentations, cervical microglandular hyperplasia and endocervical pseudodecidualization. These variables are compared with a similar previous study. Significant differences in the incidence of glandular metaplasia, dystrophic calcification, plasma cell infiltrates, hemosiderophages, and presence of nuclear atypia are noted. With increased use of the Mirena coil, histopathologists need to be aware of the characteristic and constant endometrial changes due to progestogenic and mechanical effects, despite a wide variation in the duration of usage.

Abstract
BACKGROUND Uterine polyps cause abnormal bleeding in women and conventional practice is to remove them in hospital under general anaesthetic. Advances in technology make it possible to perform polypectomy in an outpatient setting, yet evidence of effectiveness is limited. OBJECTIVES To test the hypothesis that in women with abnormal uterine bleeding (AUB) associated with benign uterine polyp(s), outpatient polyp treatment achieved as good, or no more than 25% worse, alleviation of bleeding symptoms at 6 months compared with standard inpatient treatment. The hypothesis that response to uterine polyp treatment differed according to the pattern of AUB, menopausal status and longer-term follow-up was tested. The cost-effectiveness and acceptability of outpatient polypectomy was examined. DESIGN A multicentre, non-inferiority, randomised controlled trial, incorporating a cost-effectiveness analysis and supplemented by a parallel patient preference study. Patient acceptability was evaluated by interview in a qualitative study. SETTING Outpatient hysteroscopy clinics and inpatient gynaecology departments within UK NHS hospitals. PARTICIPANTS Women with AUB - defined as heavy menstrual bleeding (formerly known as menorrhagia) (HMB), intermenstrual bleeding or postmenopausal bleeding - and hysteroscopically diagnosed uterine polyps. INTERVENTIONS We randomly assigned 507 women, using a minimisation algorithm, to outpatient polypectomy compared with conventional inpatient polypectomy as a day case in hospital under general anaesthesia. MAIN OUTCOME MEASURES The primary outcome was successful treatment at 6 months, determined by the woman's assessment of her bleeding. Secondary outcomes included quality of life, procedure feasibility, acceptability and cost per quality-adjusted life-year (QALY) gained. RESULTS At 6 months, 73% (166/228) of women who underwent outpatient polypectomy were successfully treated compared with 80% (168/211) following inpatient polypectomy [relative risk (RR) 0.91, 95% confidence interval (CI) 0.82 to 1.02]. The lower end of the CIs showed that outpatient polypectomy was at most 18% worse, in relative terms, than inpatient treatment, within the 25% margin of non-inferiority set at the outset of the study. By 1 and 2 years the corresponding proportions were similar producing RRs close to unity. There was no evidence that the treatment effect differed according to any of the predefined subgroups when treatments by variable interaction parameters were examined. Failure to completely remove polyps was higher (19% vs. 7%; RR 2.5, 95% CI 1.5 to 4.1) with outpatient polypectomy. Procedure acceptability was reduced with outpatient compared with inpatient polyp treatment (83% vs. 92%; RR 0.90, 95% CI 0.84 to 0.97). There were no significant differences in quality of life. The incremental cost-effectiveness ratios at 6 and 12 months for inpatient treatment were £1,099,167 and £668,800 per additional QALY, respectively. CONCLUSIONS When treating women with AUB associated with uterine polyps, outpatient polypectomy was non-inferior to inpatient polypectomy at 6 and 12 months, and relatively cost-effective. However, patients need to be aware that failure to remove a polyp is more likely with outpatient polypectomy and procedure acceptability lower.

Abstract
OBJECTIVE To provide guidelines for health care providers on the use of contraceptive methods to prevent pregnancy and on the promotion of healthy sexuality. OUTCOMES Overall efficacy of cited contraceptive methods, assessing reduction in pregnancy rate, safety, ease of use, and side effects; the effect of cited contraceptive methods on sexual health and general well-being; and the relative cost and availability of cited contraceptive methods in Canada. EVIDENCE Published literature was retrieved through searches of Medline and The Cochrane Database from January 1994 to January 2015 using appropriate controlled vocabulary (e.g., contraception, sexuality, sexual health) and key words (e.g., contraception, family planning, hormonal contraception, emergency contraception). Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies published in English from January 1994 to January 2015. Searches were updated on a regular basis in incorporated in the guideline to June 2015. Grey (unpublished) literature was identified through searching the websites of health technology assessment and health technology-related agencies, clinical practice guideline collections, clinical trial registries, and national and international medical specialty societies. VALUES The quality of the evidence in this document was rated using the criteria described in the Report of the Canadian Task Force on Preventive Health Care (Table 1). CHAPTER 7: INTRAUTERINE CONTRACEPTION: SUMMARY STATEMENTS 1. Intrauterine contraceptives are as effective as permanent contraception methods. (II-2) 2. The use of levonorgestrel-releasing intrauterine system (LNG-IUS) 52 mg by patients taking tamoxifen is not associated with recurrence of breast cancer. (I) 3. Intrauterine contraceptives have a number of noncontraceptive benefits. The levonorgestrel-releasing intrauterine system (LNG-IUS) 52 mg significantly decreases menstrual blood loss (I) and dysmenorrhea. (II-2) Both the copper intrauterine device and the LNG-IUS significantly decrease the risk of endometrial cancer. (II-2) 4. The risk of uterine perforation decreases with inserter experience but is higher in postpartum and breastfeeding women. (II-2) 5. The risk of pelvic inflammatory disease (PID) is increased slightly in the first month after intrauterine contraceptive (IUC) insertion, but the absolute risk is low. Exposure to sexually transmitted infections and not the IUC itself is responsible for PID occurring after the first month of use. (II-2) 6. Nulliparity is not associated with an increased risk of intrauterine contraceptive expulsion. (II-2) 7. Ectopic pregnancy with an intrauterine contraceptive (IUC) is rare, but when a pregnancy occurs with an IUC in situ, it is an ectopic pregnancy in 15% to 50% of the cases. (II-2) 8. In women who conceive with an intrauterine contraceptive (IUC) in place, early IUC removal improves outcomes but does not entirely eliminate risks. (II-2) 9. Intrauterine contraceptives do not increase the risk of infertility. (II-2) 10. Immediate insertion of an intrauterine contraceptive (10 minutes postplacental to 48 hours) postpartum or post-Caesarean section is associated with a higher continuation rate compared with insertion at 6 weeks postpartum. (I) 11. Immediate insertion of an intrauterine contraceptive (IUC; 10 minutes postplacental to 48 hours) postpartum or post-Caesarean section is associated with a higher risk of expulsion. (I) The benefit of inserting an IUC immediately postpartum or post-Caesarean section outweighs the disadvantages of increased risk of perforation and expulsion. (II-C) 12. Insertion of an intrauterine contraceptive in breastfeeding women is associated with a higher risk of uterine perforation in the first postpartum year. (II-2) 13. Immediate insertion of an intrauterine contraceptive (IUC) post-abortion significantly reduces the risk of repeat abortion (II-2) and increases IUC continuation rates at 6 months. (I) 14. Antibiotic prophylaxis for intrauterine contraceptive insertion does not significantly reduce postinsertion pelvic infection. (I) RECOMMENDATIONS: 1. Health care professionals should be careful not to restrict access to intrauterine contraceptives (IUC) owing to theoretical or unproven risks. (III-A) Health care professionals should offer IUCs as a first-line method of contraception to both nulliparous and multiparous women. (II-2A) 2. In women seeking intrauterine contraception (IUC) and presenting with heavy menstrual bleeding and/or dysmenorrhea, health care professionals should consider the use of the levonorgestrel intrauterine system 52 mg over other IUCs. (I-A) 3. Patients with breast cancer taking tamoxifen may consider a levonorgestrel-releasing intrauterine system 52 mg after consultation with their oncologist. (I-A) 4. Women requesting a levonorgestrel-releasing intrauterine system or a copper-intrauterine device should be counseled regarding changes in bleeding patterns, sexually transmitted infection risk, and duration of use. (III-A) 5. A health care professional should be reasonably certain that the woman is not pregnant prior to inserting an intrauterine contraceptive at any time during the menstrual cycle. (III-A) 6. Health care providers should consider inserting an intrauterine contraceptive immediately after an induced abortion rather than waiting for an interval insertion. (I-B) 7. In women who conceive with an intrauterine contraceptive (IUC) in place, the diagnosis of ectopic pregnancy should be excluded as arly as possible. (II-2A) Once an ectopic pregnancy has been excluded, the IUC should be removed without an invasive procedure. The IUC may be removed at the time of a surgical termination. (II-2B) 8. In the case of pelvic inflammatory disease, it is not necessary to remove the intrauterine contraceptive unless there is no clinical improvement after 48 to 72 hours of appropriate antibiotic treatment. (II-2B) 9. Routine antibiotic prophylaxis for intrauterine contraceptive (IUC) insertion is not indicated. (I-B) Health care providers should perform sexually transmitted infection (STI) testing in women at high risk of STI at the time of IUC insertion. If the test is positive for chlamydia and/or gonorrhea, the woman should be appropriately treated postinsertion and the IUC can remain in situ. (II-2B) 10. Unscheduled bleeding in intrauterine contraception users, when persistent or associated with pelvic pain, should be investigated to rule out infection, pregnancy, gynecological pathology, expulsion or malposition.

Abstract
BACKGROUND Adjuvant tamoxifen reduces the risk of breast cancer recurrence in women with oestrogen receptor-positive breast cancer. Tamoxifen also increases the risk of postmenopausal bleeding, endometrial polyps, hyperplasia, and endometrial cancer. The levonorgestrel-releasing intrauterine system (LNG-IUS) causes profound endometrial suppression. This systematic review considered the evidence that the LNG-IUS prevents the development of endometrial pathology in women taking tamoxifen as adjuvant endocrine therapy for breast cancer. OBJECTIVES To determine the effectiveness and safety of levonorgestrel intrauterine system (LNG-IUS) in pre- and postmenopausal women taking adjuvant tamoxifen following breast cancer for the outcomes of endometrial and uterine pathology including abnormal vaginal bleeding or spotting, and secondary breast cancer events. SEARCH METHODS We searched the following databases: Cochrane Menstrual Disorders and Subfertility Group Specialised Register (MDSG), Cochrane Breast Cancer Group Specialised Register (CBCG), Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Abstracts of Reviews of Effects (DARE), The Cochrane Library, clinicaltrials.gov, The World Health Organisation International Trials Registry, ProQuest Dissertations & Theses, MEDLINE, EMBASE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), PsycINFO, Web of Science, OpenGrey, LILACS, PubMed, and Google. The final search was performed in October 2015. SELECTION CRITERIA Randomised controlled trials of women with breast cancer on adjuvant tamoxifen that compared endometrial surveillance alone (control condition) versus the LNG-IUS with endometrial surveillance (experimental condition) on the incidence of endometrial pathology. DATA COLLECTION AND ANALYSIS Study selection, risk of bias assessment and data extraction were performed independently by two review authors. The primary outcome measure was endometrial pathology (including polyps, endometrial hyperplasia, or endometrial cancer) diagnosed at hysteroscopy or endometrial biopsy. Secondary outcome measures included fibroids, abnormal vaginal bleeding or spotting, breast cancer recurrence, and breast cancer-related deaths. The overall quality of evidence was rated using GRADE methods. MAIN RESULTS Four randomised controlled trials involving 543 women were identified and are included in this review. In the included studies, the active treatment arm was the 20 μg/day levonorgestrel-releasing intrauterine system (LNG-IUS) plus endometrial surveillance; the control arm was endometrial surveillance alone. In tamoxifen users, the LNG-IUS led to a reduction in the incidence of endometrial polyps over both a 12-month period (Peto OR 0.22, 95% CI 0.08 to 0.64, 2 studies, n = 212, I² = 0%) and over a long-term follow-up period (24 to 60 months) (Peto OR 0.22, 95% CI 0.13 to 0.39, 4 studies, n = 417, I² = 0%, moderate quality evidence). Also the LNG-IUS led to a reduction in the incidence of endometrial hyperplasia over a long-term follow-up period (24 to 60 months) (Peto OR 0.13, 95% CI 0.03 to 0.67, four studies, n = 417, I² = 0%, moderate quality evidence). However, it should be noted that the number of events of endometrial hyperplasia was low (n = 6). None of the trials were sufficiently powered to detect whether LNG-IUS leads to significant changes in the incidence of endometrial cancer in tamoxifen users. At 12 months of follow-up abnormal vaginal bleeding or spotting was more common in the LNG-IUS treatment group (Peto OR 7.26, 95% CI 3.37 to 15.66, 3 studies, n = 376, I² = 0%, moderate quality evidence). By 24 months of follow-up, abnormal vaginal bleeding or spotting occurred less frequently compared to 12 months of follow-up in the LNG-IUS treatment group but was still more common than the control group (Peto OR 2.72, 95% CI 1.04 to 7.10, 2 studies, n = 233, I² = 0%, moderate quality evidence). By 60 months of follow-up, no cases of abnormal vaginal bleeding or spotting were reported in either group. The numbers of events for the following outcomes were low: fibroids (n = 13), breast cancer recurrence (n = 18), and breast cancer-related deaths (n = 16). There was no evidence of a difference between the LNG-IUS treatment group and controls for these outcomes. The quality of the evidence was judged as moderate, due to limited sample sizes and low event rates for the outcome comparisons. AUTHORS' CONCLUSIONS The LNG-IUS reduces the incidence of benign endometrial polyps and endometrial hyperplasia in women with breast cancer taking tamoxifen. At 12 and 24 months of follow-up, the LNG-IUS increased abnormal vaginal bleeding or spotting among women in the treatment group compared to those in the control. There is no clear evidence from the available randomised controlled trials that the LNG-IUS prevents endometrial cancer in these women. There is no clear evidence from the available randomised controlled trials that the LNG-IUS affects the risk of breast cancer recurrence or breast cancer-related deaths. Larger studies are necessary to assess the effects of the LNG-IUS on the incidence of endometrial cancer, and to determine whether the LNG-IUS might have an impact on the risk of secondary breast cancer events.

Combined effects of goserelin and tamoxifen on estradiol level, breast density, and endometrial thickness in premenopausal and perimenopausal women with early-stage hormone receptor-positive breast cancer: a randomised controlled clinical trial. Br J Cancer 2013; 109:582-8. [PMID: 23860520 PMCID: PMC3738136 DOI: 10.1038/bjc.2013.324] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2013] [Revised: 05/28/2013] [Accepted: 06/04/2013] [Indexed: 12/02/2022] Open
Abstract
Background: This study is to investigate the effects of geserelin+tamoxifen (TAM) on estradiol level, breast density (BD), endometrial thickness (ET), and blood lipids in premenopausal and perimenopausal women with hormone receptor-positive early-stage breast cancer. Methods: This study recruited 110 premenopausal and perimenopausal patients with hormone receptor-positive early-stage breast cancer between 22 June 2008 and 31 December 2009 and randomly assigned them to receive either goserelin plus TAM or TAM alone for 1.5 years. Blood levels of sex hormones and lipids and ET were determined at 0, 3, 6, 12, and 18 months. Contralateral BD was also measured at 0, 12, and 18 months. Results: Five participants dropped out of the goserelin plus TAM group, and two participants dropped out of the TAM-alone group before initiation of endocrine therapy. The rest of patients received scheduled treatment and 3 years of median follow-up. No serious adverse effects were observed, and only two local recurrences have been observed in these patients. Estradiol level and BD were lower in the goserelin plus TAM group than in the TAM-alone group (P<0.05). The endometrium in the goserelin plus TAM group was significantly thinner than that in the TAM-alone group (P<0.05), and women in the TAM-alone group exhibited endometrial thickening over the course of the study. Furthermore, no significant differences in blood lipid levels were reported between the two groups. Conclusion: The data from the current study demonstrated that the addition of goserelin to TAM results in downregulation of estradiol level, followed by significant reduction in BD and ET in premenopausal and perimenopausal women with hormone receptor-positive breast cancer, which may eventually lead to better outcome in these patients.

Abstract
Hormonal contraceptives are not only effective methods of birth control but also are effective at treating and/or preventing a variety of gynecologic and general disorders. Hormonal contraceptives can decrease the severity of acne, correct menstrual irregularities, treat endometriosis-associated pain, decrease bleeding associated with uterine myomas, decrease pain associated with menstrual periods, moderate symptoms associated with premenstrual syndrome, reduce menstrual migraine frequency, and increase bone mineral density as well as decrease the risk of specific cancers such as endometrial and ovarian cancer. Women need to receive this information to guide them in their decisions regarding choice of contraception as well as treatment options for gynecologic disorders.

Abstract
BackgroundUterine leiomyomas are extremely common in surgical pathology practice and in the vast majority there are no issues in diagnosis. Progestogens are widely prescribed drugs for a variety of indications, including abnormal uterine bleeding, and are often given to women with leiomyomas but the pathological features of leiomyomas treated with progestogens are poorly described.MethodsWe report the pathological features in eight cases of uterine leiomyomas in women who had been treated with oral progestogens or a progestogen-containing intrauterine device; all cases were received in consultation because the features raised concern for leiomyosarcoma, smooth muscle tumour of uncertain malignant potential or a benign leiomyoma with unusual features. Additionally, we reviewed a series of cases of uterine leiomyomas (n=99) in women who exhibited progestogenic effects in the endometrium.ResultsThe morphological features in the consult cases, which were widespread and marked and which varied somewhat from case to case, included small and/or large areas of infarct-type necrosis (sometimes mimicking coagulative tumour cell necrosis) with surrounding increased cellularity, mitotic activity, nuclear pyknosis, cytoplasmic eosinophilia, epithelioid morphology, stromal oedema, haemorrhage, and myxoid change and infiltration by CD56 positive granulated lymphocytes. Sometimes the features resulted in an almost deciduoid appearance. Similar features were present to a minor degree in significant numbers of the additional series of cases.ConclusionsPathologists should be aware of these progestogen-associated features when reporting uterine leiomyomas whether or not the clinician has indicated that the woman is taking progestogens since otherwise a diagnosis of leiomyosarcoma or smooth muscle tumour of uncertain malignant potential may be rendered. Useful features in suggesting a benign leiomyoma, in addition to recognition of the morphological features described which, in combination, are characteristic of progestogens, are the lack of true nuclear atypia and the low mitotic activity away from the abnormal areas.

Abstract
OBJECTIVE To compare the efficacy of a levonorgestrel-releasing intrauterine system (LNG-IUS) with that of a low-dose combined oral contraceptive (COC) in reducing fibroid-related menorrhagia. METHODS In this single-center, open, randomized clinical trial, 58 women with menorrhagia who desired contraception were randomized to receive a LNG-IUS or COC. The outcomes included treatment failure, defined as the need for another treatment; menstrual blood loss (MBL) by the alkaline hematin method and a pictorial assessment chart (PBAC); hemoglobin levels; and "lost days." RESULTS Treatment failed in 6 women (23.1%) in the LNG-IUS group and 11 (37.9%) in the COC group, for a hazard ratio of 0.46 (95% CI, 0.17-1.17, P=0.101). Using the alkaline hematin test, the reduction of MBL was significantly greater in the LNG-IUS group (90.9% ± 12.8% vs 13.4% ± 11.1%; P<0.001). Using PBAC scores, the reduction was also significantly greater in the LNG-IUS group (88.0% ± 16.5% vs 53.5% ± 5 1.2%; P=0.02). Moreover, hemoglobin levels increased from 9.7 ± 1.9g/dL to 11.7 ± 1.2g/dL (P<0.001) and lost days decreased from 8.2 ± 3.3 days to 1.3 ± 1.5 days (P=0.003) in the LNG-IUS group. CONCLUSION Although the rate of treatment failure was similar in both groups, the LNG-IUS was more effective in reducing MBL than the COC in women with fibroid-related menorrhagia.

Abstract
Intrauterine devices (IUDs) provide highly effective, long-term, safe, reversible contraception, and are the most widely used reversible contraceptive method worldwide. The levonorgestrel-releasing intrauterine system (LNG-IUS) is a T-shaped IUD with a steroid reservoir containing 52 mg of levonorgestrel that is released at an initial rate of 20 μg daily. It is highly effective, with a typical-use first year pregnancy rate of 0.1% - similar to surgical tubal occlusion. It is approved for 5 years of contraceptive use, and there is evidence that it can be effective for up to 7 years of continuous use. After removal, there is rapid return to fertility, with 1-year life-table pregnancy rates of 89 per 100 for women less than 30 years of age. Most users experience a dramatic reduction in menstrual bleeding, and about 15% to 20% of women become amenorrheic 1 year after insertion. The device's strong local effects on the endometrium benefit women with various benign gynecological conditions such as menorrhagia, dysmenorrhea, leiomyomata, adenomyosis, and endometriosis. There is also evidence to support its role in endometrial protection during postmenopausal estrogen replacement therapy, and in the treatment of endometrial hyperplasia.

Abstract
BACKGROUND Adjuvant tamoxifen reduces the risk of breast cancer recurrence in women with estrogen receptor-positive breast cancer. Tamoxifen also increases the risk of postmenopausal bleeding, endometrial hyperplasia, polyps, and endometrial cancer. The levonorgestrel-releasing intrauterine system (LNG-IUS) causes profound endometrial suppression. This systematic review considered the evidence that the LNG-IUS prevents the development of endometrial pathology in women taking tamoxifen as adjuvant endocrine therapy for breast cancer. OBJECTIVES To determine the effectiveness of the levonorgestrel intrauterine system in preventing the development of endometrial hyperplasia, polyps, and adenocarcinoma in pre and postmenopausal women taking adjuvant tamoxifen following breast cancer. SEARCH STRATEGY All reports which described randomised controlled trials of effects of the levonorgestrel intrauterine system on the endometrium in breast cancer patients taking adjuvant tamoxifen were obtained through searches of the Menstrual Disorders and Subfertility Group Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2009), MEDLINE (1996 to August 2009), EMBASE (1980 to August 2009), CINAHL (Cumulative Index to Nursing and Allied Health Literature) (1982 to August 2009). SELECTION CRITERIA Randomised controlled trials of women with breast cancer on adjuvant tamoxifen that compared endometrial surveillance or placebo alone versus the LNG-IUS. Women with known endometrial pathology or contraindications to LNG-IUS were excluded. DATA COLLECTION AND ANALYSIS Only two randomised controlled trials were identified and are included in this review. Risk of bias assessment and data extraction were performed independently by two review authors. The outcome measures were endometrial pathology (including polyps, endometrial hyperplasia, or adenocarcinoma) diagnosed at hysteroscopy or endometrial biopsy; any reported side effects of treatment; and abnormal vaginal bleeding. MAIN RESULTS In both included studies, the active treatment arm was the Mirena 20 mug/day levonorgestrel-releasing intrauterine device (Bayer Health Care, US). The LNG-IUS in tamoxifen users led to a significant reduction in the incidence of endometrial polyps (Peto odds ratio 0.14, 95% confidence interval 0.03 to 0.61). Neither trial was sufficiently powered to detect whether LNG-IUS leads to significant changes in the incidence of endometrial hyperplasia or adenocarcinoma in tamoxifen users, nor whether LNG-IUS leads to any increased risk of breast cancer recurrence. There appeared to be more vaginal bleeding in the Mirena treatment group, in the first six months only. However, the bleeding patterns at 12 months were fairly similar for both groups. AUTHORS' CONCLUSIONS The Mirena LNG-IUS appears to prevent the development of benign endometrial polyps in breast cancer patients taking tamoxifen, over a one-year period. There is no clear evidence from the available randomised controlled trials that LNG-IUS prevents endometrial hyperplasia or adenocarcinoma in these patients. Larger studies are necessary to assess the effects of LNG-IUS in preventing endometrial hyperplasia and endometrial cancer, and to determine whether LNG-IUS might have an impact on the risk of breast cancer recurrence.

Abstract
Although fertility declines with advancing age as the woman approaches the menopause, some risk of pregnancy persists, and effective contraception needs to be offered to avoid an unintended pregnancy. An older woman may have menstrual dysfunction or climacteric symptoms and these factors would need consideration when making the choice of contraception. Low-estrogen dose combined oral contraceptives may be prescribed to healthy non-smoking women up to about 50 years of age. The progestogen-only pill may be an appropriate option in an older woman with declining fertility. The copper intrauterine device is an optimal method for parous women free of pre-existing menstrual problems. The levonorgestrel-releasing intrauterine system is considered the contraceptive method of choice for perimenopausal women with menstrual dysfunction. The woman should be provided with individualized advice so that she has a choice between the newer, effective, largely safe, reversible methods and sterilization.

Abstract
PURPOSE OF REVIEW Hereditary non-polyposis colorectal cancer (HNPCC) or Lynch syndrome is characterized by a number of other cancers including colorectal, endometrial and ovarian cancer. This review covers the gynaecological aspects of managing women with HNPCC: diagnostic criteria, molecular tests for diagnosis, cancer risks and different strategies for surveillance and prevention. RECENT FINDINGS Studies correcting for ascertainment bias found slightly lower penetrance estimates than those obtained from high-risk families. HNPCC linked ovarian cancer presents at an earlier age and stage and has similar survival rates as sporadic cancer. In endometrial tumours, microsatellite instability or immunohistochemistry has limited effectiveness in selecting individuals for genetic testing, due to molecular differences. Population-based data indicate that a significant proportion of mismatch repair gene carriers would be missed by current clinical criteria. Effective risk prediction models complement clinical risk assessment. Effectiveness of screening is unproven and prophylactic surgery is the best preventive option for women who have completed their families. Multimodal screening protocols from the age of 30-35 years are being evaluated. SUMMARY Risk of endometrial cancer in women with Lynch syndrome is as high as the risk of colorectal cancer. Further research is needed to identify the appropriate strategy for clinical risk assessment and optimize screening. A multidisciplinary approach is necessary to manage these women.

Abstract
Hormonal contraceptives have been a part of clinical practice for more than 40 years, and family planning programs, based largely on contraceptive provision, are regarded as one of the most successful public health interventions of the 20th century. Thus, discussion of family planning issues and contraceptive considerations has become an integral component of women's health care and one of the benchmarks of the traditional annual well-women visit. In terms of cost-effectiveness, prevention of unplanned pregnancies through contraceptive use has repeatedly been shown to be a highly cost-effective use of health care dollars. Options for effective hormonal contraception have expanded tremendously and include a variety of delivery options, including the pills both in traditional 21/7 format, and more recently in a 24/4 format, as well as a vaginal ring, a skin patch, implants, and the hormonally medicated intrauterine device. Importantly, the overall risks associated with hormonal contraceptives have been reduced as compared with older formulations, even for women with medical conditions. Many modern hormonal contraceptives also offer valuable noncontraceptive benefits. To help clinical decision making, a number of evidence-based guides have been published, and the American College of Obstetricians and Gynecologists has recently updated their practice bulletin on contraception use in women with medical conditions. In general, clinical protocols for provision of hormonal contraceptives have been streamlined, and unnecessary practices, tests, and procedures are identified and discouraged. In this review, we will summarize both technical and programmatic aspects of hormonal contraceptive use, and methods are discussed in order of efficacy from highest to lowest.

Abstract
OBJECTIVE The purpose of this study was to evaluate the long-term efficacy and prognosis of hysteroscopic resection and coagulation of the base of endometrial polyps with focal atypia in fertile women with or without progestin suppression. STUDY DESIGN We conducted a quasi-randomized trial in which conservative treatment was offered to 21 patients who had endometrial polyps with focal atypia and a surrounding normal endometrium. The polyps were analyzed separately from their bases. Random biopsy specimens were taken from 4 standard places of the endometrium. RESULTS Eighteen women (10 women with an intrauterine device and 8 women with no intrauterine device) completed the follow-up procedure. After 5 years, we found no difference in the 2 groups regarding recurrence of atypical polyps. CONCLUSION Conservative resectoscopic treatment may be considered in fertile women with atypical polyps if polyp base and surrounding endometrium are benign. If women want to become pregnant at short term, the use of progestins can be delayed, with a strict follow-up procedure. Larger studies should be encouraged.

Abstract
PURPOSE We sought to study the association between intrauterine device (IUD) use and endometrial cancer. METHODS A comprehensive search of literature published through April 2007 was conducted, studies reviewed, and data abstracted. Data from ten studies were pooled and analyzed using both fixed- and random-effects models to examine the association of ever use of an IUD and endometrial cancer. RESULTS Based on the random effects model, a protective crude association between IUD use and endometrial cancer was observed (odds ratio [OR] = 0.39; 95% confidence interval [CI] = 0.29-0.51; heterogeneity p < 0.001) with a pooled adjusted risk of OR = 0.54 (95% CI, 0.47-0.63; heterogeneity p = 0.40). A decreased risk of endometrial cancer also was seen for increased years of IUD use (OR for 5 years of use 0.88; 95% CI = 0.84-0.92; n = 5; heterogeneity p = 0.14), increased years since last IUD use (OR for 5 years of use 0.91; 95% CI, 0.86-0.95; n = 4; heterogeneity p = 0.02), and increased years since first IUD use (OR for 5 years of use 0.89; 95% CI, 0.83-0.95; n = 4; heterogeneity p = 0.04). CONCLUSIONS Our results suggest that nonhormonal IUD use may be associated with a decreased risk for endometrial cancer; however, the exact mechanism for this association is unclear. Future investigations should address the difference in the proposed association by specific type of IUDs.

Abstract
The levonorgestrel-containing intrauterine system is an extremely effective, reversible and safe form of long-term yet reversible birth control. In view of its efficacy, it is a safer alternative to permanent contraceptive methods such as sterilization. It is especially useful in situations where use of estrogen-containing contraceptives is contraindicated. While menstrual disturbances are a common side effect, proper counseling improves compliance. In addition to its contraceptive effect, the levonorgestrel intrauterine system offers potential therapeutic benefits in other clinical contexts, including menorrhagia, symptomatic fibroids, endometriosis, and endometrial protection.

Abstract
Purpose The combination of hormone replacement therapy (HRT) and low-dose tamoxifen may retain the benefits while reducing the risks of either agent. We assessed the optimal biologic dose and schedule of tamoxifen in HRT users using surrogate end point biomarkers and menopausal symptoms. Subjects and Methods Two hundred ten current or de novo HRT users were randomly assigned to one of the following four arms: tamoxifen 1 mg/day and placebo/week, placebo/day and tamoxifen 10 mg/week, tamoxifen 5 mg/day and placebo/week, or both placebos for 12 months. The primary end point was the change of plasma insulinlike growth factor 1 (IGF-I) through 12 months, and secondary end points were IGF-I/IGF binding protein-3 (IGFBP-3) ratio, fibrinogen, antithrombin III, C reactive protein, C-telopeptide, mammographic percent density, and endometrial thickness. Endometrial proliferation was assessed by Pipelle biopsy in superficial, deep glandular, and stromal compartments after 12 months. Results Compared with placebo, IGF-I declined in all tamoxifen arms (P = .005), with a greater change on 5 mg/day (P = .019 v 10 mg/week or 1 mg/day). Tamoxifen increased IGFBP-3 and lowered antithrombin-III, C reactive protein, and mammographic density, with greater effects of 5 mg/day. Tamoxifen increased endometrial thickness but not Ki-67 expression, which was lower on 5 mg/day among the three doses. Menopausal symptoms were not significantly worsened by tamoxifen. Conclusion Doses of tamoxifen ≤ 5 mg/day modulate favorably biomarkers of breast carcinogenesis and cardiovascular risk in HRT users with no increase of endometrial proliferation and menopausal symptoms. A dose of 5 mg/day was the most effective and has been selected for a phase III trial in HRT users.

Abstract
OBJECTIVE To study the recurrence of breast cancer among patients who were using the levonorgestrel-releasing intrauterine system (LNG IUS). DESIGN A retrospective, controlled cohort analysis. SETTING Six Belgian hospitals. PATIENT(S) We identified 79 breast cancer patients who used the LNG IUS, and we selected a control group of 120 patients with no history of LNG IUS use and who were closely matched for age at diagnosis, tumor stage, tumor grade, and treatment modalities. Two subgroups were identified: [1] breast cancer patients who continued using the LNG IUS after diagnosis and [2] breast cancer patients who began using an LNG IUS after treatment for breast cancer. INTERVENTION(S) Patient's data were collected and survival analysis was performed. MAIN OUTCOME MEASURE(S) Breast cancer recurrence rate. RESULT(S) There was a recurrence rate of 21.5% (17/79) among LNG IUS users and of 16.6% (20/120) among the control group (adjusted hazard ratio, 1.86; 95% confidence interval, 0.86-4.00; no statistically significant difference). Subgroup analysis showed that women using the LNG IUS (n = 38) at the time of breast cancer diagnosis (and who continued its use) had a statistically significantly increased risk of recurrence (adjusted hazard ratio, 3.39; 95% confidence interval, 1.01-11.35) compared with patients in the control group. There was 47.4% (18/38) nodal involvement in this subgroup, and all patients who recurred had metastatic disease. CONCLUSION(S) Overall, we did not find an increased risk of breast cancer recurrence associated with use of the LNG-IUS. However, in a subgroup analysis of women who developed breast cancer while using an LNG IUS and who continued to use the LNG IUS, we found a higher risk of recurrence of borderline statistical significance. Additional research is needed to confirm or refute these findings.

Abstract
Hemostatic disorders in women are frequently associated with long-standing menorrhagia. This leads to significant morbidity and adversely affects quality of life. Management of these women poses a particular challenge; medical treatments may be contraindicated, and surgery carries additional risks. The levonorgestrel intrauterine system (LNG-IUS) has been shown to be highly efficacy in reducing menstrual blood loss in women with normal coagulation. It is also a reliable and reversible contraceptive. Data on the use of this system in women with bleeding disorders or those receiving anticoagulant therapy are limited. Analysis of data from four reported studies suggests that LNG-IUS is a viable and safe option for the management of menorrhagia in these women. Whether the underlying hemostatic disorders lead to a shorter duration of action or prolonged irregular bleeding/spotting post insertion is unknown and requires large prospective studies. Proper counselling remains crucial for patients' satisfaction.

Abstract
Local intrauterine delivery of levonorgestrel (LNG) results in extensive decidualization of endometrial stromal cells, atrophy of the glandular and surface epithelium and changes in vascular morphology (suppression of spiral artery formation and presence of large dilated vessels). With endometrial exposure to LNG, there is down-regulation of sex steroid receptors in all cellular components. As a consequence of endometrial sex steroid receptor down-regulation, there is perturbation of progesterone-regulated locally acting mediators, and the integrity of blood vessel walls is disturbed. Thus, intrauterine LNG administration results in modulation of local mediators regulating endometrial function. To date, no single factor has been identified where the expression correlates closely with unscheduled breakthrough bleeding (BTB). BTB is a common side effect and reason for discontinuation of LNG-IUS use. Much remains to be determined about the mechanisms involved in suppression of menstruation, BTB episodes and the local endometrial environment with local LNG administration.

Abstract
CONTEXT Progestins delivered by a variety of routes have been demonstrated, in addition to their high contraceptive effect, to have substantial benefits in the treatment of various gynecological disorders, and the intrauterine route has particular efficacy in treating endometrial and myometrial disorders. It should be possible to extend this to prevention of disease. THERAPY OF GYNECOLOGICAL DISEASE Those conditions for which there is most evidence of therapeutic benefit from intrauterine release of progestins include heavy menstrual bleeding (due to most causes), endometrial hyperplasia, endometriosis and adenomyosis. PREVENTION OF GYNECOLOGICAL DISEASE Reasonable evidence exists to support the findings that intrauterine levonorgestrel helps to prevent the development of uterine fibroids, endometriosis, endometrial hyperplasia, acute episodes of pelvic infection and a wide range of menstrual symptoms. There is also promise of prevention of endometrial carcinoma, endometrial polyps, infertility and perhaps adenomyosis. CONCLUSIONS There is a need for specific studies to further explore the prevention of these gynecological conditions which can cause major health disturbances and community distress.

Abstract
BACKGROUND One of the mechanisms by which intrauterine devices (IUDs) prevent pregnancy is the creation of a sterile inflammatory response in the endometrium. Additionally, hormone-releasing IUDs or intrauterine systems (IUSs) release progestins or progesterone into the uterus. Both of these mechanisms may affect users' risk for neoplasia. STUDY DESIGN We searched the PubMed database for studies on IUD use and risk for neoplasia conducted between 1960 and September 2006 and published in all languages. We excluded case reports and case series. For the association between ever using an IUD and risk for endometrial cancer, we conducted a meta-analysis using a Bayesian random-effects model to account for between-study heterogeneity. RESULTS We found no evidence of increased risk for neoplasia with IUD use. Nine case-control studies and one cohort study found reduced risks for endometrial cancer with having ever used an IUD (pooled adjusted odds ratio=0.6, 95% confidence interval=0.4-0.7). No trend in associations was observed with characteristics of IUD use, type of IUD and histologic type of cancer. Four case-control studies found no association between IUD use and risk for cervical cancer. One study found no increased incidence of breast cancer among levonorgestrel-releasing IUS users as compared with the general population in Finland. Finally, three studies found no association between IUD use and occurrence of hydatidiform moles or malignant sequelae. CONCLUSIONS Use of an IUD does not appear to increase the risk for neoplasia. While nearly all studies found that IUD use was associated with a decreased risk for endometrial cancer, it remains unclear whether this association is causal.

Abstract
Annual occurrence of breast cancer is constantly increasing in France. In 2000, the number of breast cancer cases for women of 30-49 years was estimated at 9,918, which represents 23.7% of all breast cancer cases diagnosed that year. The levonorgestrel-releasing intrauterine device (IUD LNG) is one of the most frequently used coils in France. Because contraception is an important matter for women whose ovarian function survived cancer treatments, the question of whether to use such device on a woman with breast cancer has become a frequent and controversial gynaecological issue. With the review of available literature as a basis, we have tried to answer the following questions. First, whether the use of IUD LNG increases the risk of breast cancer: there is at the moment no "A" level answer available. According to the only study published, which may be considered "C" level, there is no such increase. Second, whether the use of IUD LNG counterbalances the endometrial effects of Tamoxifene: based on a limited level of evidence via a single randomised controlled trial on a small number of patients for one year only, this device appears to be able to prevent benign endometrial modifications. However, there is no conclusive study regarding its effectiveness on the prevention of endometrium adenocarcinoma caused by Tamoxifene. In addition, there are numerous uncertainties as to whether levonorgestrel presence in the plasma would have a systemic prejudicial impact. Third, whether a woman with a personal antecedent of breast cancer can safely use DIU LNG: it is necessary to remove it promptly upon suspicion or diagnosis, to dissuade its use in case of current cancer, and, in the event of cancer remission for more than 5 years, to generally avoid this contraceptive method except on a case by case basis and with a regular medical follow-up. In the latter situation, the use of IUD LNG can be considered only after a multidisciplinary collective formal decision and after the woman gave her informed consent.
