Choi E, Lee JK, Baek JK, Chung Y, Kim H, Yun BH, Seo SK. Hormone replacement therapy and breast cancer incidence in Korean women. Maturitas 2024; 183:107946. [PMID: 38412593 DOI: 10.1016/j.maturitas.2024.107946] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2023] [Revised: 02/06/2024] [Accepted: 02/15/2024] [Indexed: 02/29/2024]
Abstract
OBJECTIVES After the 2002 Women's Health Initiative (WHI) study, the global use of menopausal hormone therapy (MHT) declined, and despite subsequent studies indicating a low risk of breast cancer, concerns about MHT usage persist. We examined the relationship between changes in MHT use and changes in the incidence of breast cancer from 2002 to 2020 in South Korea. STUDY DESIGN This study used tumor registry information from 2002 to 2020 from the Korean Statistical Information Service and analyzed the incidence rate of invasive breast cancer in women, who were divided into two age groups: <50 and >50 years. The numbers of MHT prescriptions in Korea between 2002 and 2020 was determined from pharmacy data. RESULTS The incidence of breast cancer per 100,000 women in South Korea increased from 34.3 in 2002 to 96.4 in 2020. Breast cancer incidence rates increased annually in both groups of women (those aged under and over 50 years), with no significant difference between the two (p = 0.614). Prescriptions for estrogen therapy (ET) in 2020 were 52.7 % lower than those in 2002. Prescriptions for estrogen-progesterone therapy (EPT) decreased by 27.9 % over the same period. Conversely, tibolone prescriptions, which had initially decreased by 25.4 % in 2004, subsequently showed a steady increase and were 93.6 % higher in 2020 than in 2002. CONCLUSION The incidence of breast cancer increased annually in Korean women of all ages; however, the use of ET and EPT for MHT has declined since 2002, particularly the use of EPT after 2010. MHT, especially EPT, did not significantly increase the incidence of breast cancer in Korean women.

Abstract
Tibolone, a selective tissue estrogenic activity regulator, is a synthetic steroid with distinct pharmacological and clinical characteristics in contrast to conventional menopausal hormone therapy. Tibolone induces estrogenic activity in the brain, vagina, and bone but remains inactive in the endometrium and breast. In particular, several studies have investigated whether tibolone usage increases the risk of breast cancer. This study aims to determine the effects of tibolone on the breast by focusing on the relation between tibolone use and breast cancer. Our investigation emphasizes recent studies, particularly those based on Asian populations.

Yuk JS, Lee JS, Park JH. Menopausal hormone therapy and risk of dementia: health insurance database in South Korea-based retrospective cohort study. Front Aging Neurosci 2023; 15:1213481. [PMID: 37744387 PMCID: PMC10512830 DOI: 10.3389/fnagi.2023.1213481] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2023] [Accepted: 08/21/2023] [Indexed: 09/26/2023] Open
Abstract
Introduction Menopausal hormone therapy (MHT) is used to alleviate the symptoms associated with menopause, despite the lack of recommendations for MHT in preventing dementia. Recent nationwide studies have explored the association between MHT and dementia risk, but the findings remain limited. This study aims to investigate the association between MHT and the incidence of Alzheimer's disease (AD) and non-AD dementia using national population data from Korea. Methods We conducted a retrospective study using data from the National Health Insurance Service in Korea between January 1, 2002, and December 31, 2019. Women over 40 years were eligible for this study and classified into the MHT or non-MHT groups. The MHT group consisted of women who used Tibolone (TIB), combined estrogen plus progestin by the manufacturer (CEPM), estrogen, combined estrogen plus progestin by a physician (CEPP), and transdermal estrogen during menopause. We compared the risk of dementia between the MHT and non-MHT groups. Results The study included 1,399,256 patients, of whom 387,477 were in the MHT group, and 1,011,779 were in the non-MHT group. The median duration of MHT was 23 months (range: 10-55 months). After adjusting for available confounders, we found that different types of MHT had varying effects on the occurrence of dementia. TIB (HR 1.041, 95% confidence interval (CI) 1.01-1.072) and oral estrogen alone (HR 1.081, 95% CI 1.03-1.134) were associated with a higher risk of AD dementia. In contrast, there was no difference in the risk of AD dementia by CEPM (HR 0.975, 95% CI 0.93-1.019), CEPP (HR 1.131, 95% CI 0.997-1.283), and transdermal estrogen (HR 0.989, 95% CI 0.757-1.292) use. The use of TIB, CEPM, and oral estrogen alone increased the risk of non-AD dementia (HR 1.335, 95% CI 1.303-1.368; HR 1.25, 95% CI 1.21-1.292; and HR 1.128, 95% CI 1.079-1.179; respectively), but there was no risk of non-AD dementia in the other MHT groups (CEPP and topical estrogen). Conclusion Our findings indicate that MHT has varying effects on the incidence of AD and non-AD dementia. Specifically, TIB, CEPM, and oral estrogen alone increase the risk of non-AD dementia, while transdermal estrogen is not associated with dementia risk. It is essential to consider the type of MHT used when assessing the risk of dementia in women.

Abstract
Background Tibolone is an alternative to conventional estrogen and progesterone in relieving post-menopausal symptoms in Indian women. Material and Methods A prospective short-term observational study was done at a tertiary care teaching hospital in New Delhi from November 2019 to September 2021. Fifty-three women, less than 60 years of age, presenting with moderate to severe intensity of menopausal symptoms as assessed by measuring menopausal rating score (MRS > 8) were enrolled and given Tibolone 2.5 mg daily for 3 months. Improvements in symptoms were seen at 1 month and 3 months. Side effects were also noted. Results Marked improvement was seen as reduction in scores of psychological, somatic and genitourinary symptoms was noted. The psychological symptoms reduced from 8.92 ± 1.959 to 2.905 ± 1.042, the somatic symptoms decreased from 8.33 ± 2.299 to 3.4 ± 1.167, and genitourinary symptoms decreased from 3.64 ± 1.42 to 2.150 ± 0.948 after 3 months of treatment with Tibolone. Only 3 patients (5.6%) experienced vaginal spotting with no major side effects. Conclusions Tibolone is a highly effective and well accepted drug to reduce moderate to severe menopausal symptoms, especially psychological symptoms including depression.

Abstract
Some women experience bothersome symptoms around the time of menopause that may have a negative impact on their quality of life and prompt them to seek treatments. Menopausal hormone therapy was historically the treatment of choice. However, medical contraindications and personal preference for nonhormonal therapy have prompted the evaluation of a range of nonhormonal pharmacologic and non-pharmacologic therapies. This review provides an update focusing on the latest evidence-based approach for the management of bothersome symptoms of menopause.

Abstract
BACKGROUND This study aimed to explore the molecular mechanisms of tibolone treatment in postmenopausal women. METHODS The gene set enrichment profile, GSE12446, which includes 9 human endometrial samples from postmenopausal women treated with tibolone (tibolone group) and 9 control samples (control group), was downloaded from GEO database for analysis. Differentially expressed genes (DEGs) in tibolone vs. control groups were identified and then used for function and pathway enrichment analysis. Protein-protein interaction (PPI) network and module analyses were also performed. Finally, drug-target interaction was predicted for genes in modules, and then were validated in Pubmed. RESULTS A total of 238 up-regulated DEGs and 72 down-regulated DEGs were identified. These DEGs were mainly enriched in various biological processed and pathways, such as cilium movement (e.g., CCDC114 and DNAI2), calcium ion homeostasis, regulation of hormone levels and complement/coagulation cascades. PPI network contained 368 interactions and 166 genes, of which IGF1, DNALI1, CCDC114, TOP2A, DNAH5 and DNAI2 were the hue genes. A total of 96 drug-gene interactions were obtained, including 94 drugs and eight genes. TOP2A and HTR2B were found to be targets of 28 drugs and 38 drugs, respectively. Among the 94 obtained drugs, only 12 drugs were reported in studies, of which 7 drugs (e.g., epirubicin) were found to target TOP2A. CONCLUSIONS CCDC114 and DNAI2 might play important roles in tibolone-treated postmenopausal women via cilium movement function. TOP2A might be a crucial target of tibolone in endometrium of postmenopausal women.

Abstract
OBJECTIVE Few studies have examined whether tibolone (TIB), a type of hormone replacement therapy widely used in Asia and Europe, affects dementia risk in postmenopausal women. Our study aims to investigate the association of TIB and dementia risk in Korean women aged 50-80 years. METHODS A population-based longitudinal study was conducted using the Korean National Health Insurance Service claims database merged with national health examination data from 2002 to 2015. Among 13,110 participants, exposure to TIB was determined using the standardized defined daily dose (DDD) system from 2003 to 2007. Starting from 2007, participants were followed up for overall dementia, Alzheimer's disease (AD) and vascular dementia (VD) until 2015. Cox proportional hazards regression was used to determine the adjusted hazard ratios (aHRs) and 95% confidence intervals (CIs) of dementia according to TIB use. RESULTS TIB use was not significantly associated with the risk of total dementia (aHR = 1.040; 95% CI = 0.734-1.472; p = .827), AD (aHR = 0.949; 95% CI = 0.652-1.381; p = .785) and VD (aHR = 1.245; 95% CI = 0.631-2.457; p = .528). CONCLUSIONS Our results suggest that TIB use does not have a significant association with dementia risk. Further randomized controlled trials are necessary to elucidate the role of exogenous hormones in the development of dementia.

Abstract
Tibolone (TIB), a selective tissue estrogenic activity regulator (STEAR) in clinical use by postmenopausal women, activates hormonal receptors in a tissue-specific manner. Estrogenic activity is present mostly in the brain, vagina, and bone, while the inactive forms predominate in the endometrium and breast. Conflicting literature on TIB's actions has been observed. While it has benefits for vasomotor symptoms, bone demineralization, and sexual health, a higher relative risk of hormone-sensitive cancer has been reported. In the brain, TIB can improve mood and cognition, neuroinflammation, and reactive gliosis. This review aims to discuss the systemic effects of TIB on peri- and post-menopausal women and its role in the brain. We suggest that TIB is a hormonal therapy with promising neuroprotective properties.

Abstract
Background and Objectives: Hormonal replacement therapy (HRT) is effective in treating many debilitating symptoms of menopause. However, its use in women with uterine fibroids is widely debated, based on the susceptibility of these tumors to sexual steroids. This review aims to ascertain the effects of HRT on leiomyomas development and growth in postmenopausal women. Materials and Methods: Electronic databases (i.e., MEDLINE, Scopus, ClinicalTrials.gov, EMBASE, Sciencedirect, the Cochrane Library at the CENTRAL Register of Controlled Trials, Scielo) were searched from January 1990 until May 2019. All English-written studies evaluating the impact of various HRT regimens on uterine leiomyomas were selected. Results: Seventeen papers, considering a total of 1122 participants, were included. Fifteen of these were prospective trials, of which nine were randomized controlled trials. The remaining two works were a retrospective observational trial and a retrospective case series respectively. Five studies evaluated the effects of tibolone, also comparing it with various estrogen/progestin combinations, while two were about raloxifene. Thirteen studies compared different combinations of estrogens/progestins, the most common being transdermal estrogens (used in nine studies) and medroxyprogesterone acetate at different doses (used in 10 studies). Conclusions: For women with uterine fibroids, the choice of the most appropriate HRT regimen is crucial to avoid leiomyomas growth and the symptoms possibly related to it. Available data are conflicting, but suggest that uterine fibroids might be influenced by HRT, without representing an absolute contraindication to hormonal replacement therapy. Women with uterine fibroids subjected to HRT should be periodically examined and hormonal treatment should be discontinued if leiomyomas appear to increase in size. Moreover, the minimal effective dose of progestin should be employed.

Abstract
OBJECTIVE The objective of this study was to evaluate the effects of switching from hormone therapy to tissue-selective estrogen complex (TSEC) in women who experience vaginal bleeding or breast discomfort. METHODS This retrospective cohort study included 82 postmenopausal women who received TSEC after switching from another hormone therapy due to adverse events. Changes in symptoms and imaging after switching to TSEC were evaluated. RESULTS The mean age was 56.9 years. The women were switched to TSEC due to vaginal bleeding in 56.1% and breast discomfort in 47.6% (multiple choices were allowed). After the switch, almost all women (97.6%) experienced an improvement in adverse events. However, 27% of the women had worsening of vasomotor symptoms, which was more common when hormone therapy was changed from 2 mg of estradiol (41.7%) compared with 1 mg of estradiol (16.7%), 0.625 mg of conjugated estrogen (30%), or tibolone (12.5%). Images of breast lesions and fibroids before the switch were assessed, showing no change in most women. CONCLUSIONS This study suggests that TSEC is a good option for women who have breast discomfort or persistent bleeding during other hormone therapy when taking into account the differences in estrogen dose.

Abstract
Menopause is an important transition in the life of women. It has been estimated that by the year 2030, worldwide 1.2 billion women will be menopausal. The most bothersome symptoms of menopause are believed to be due to declines in estrogen levels in postmenopausal women. Thus, hormone therapy is an effective treatment option for menopausal women, although prolonged use of hormone therapy is associated with a slightly increased risk of breast cancer, thromboembolism, and stroke. A literature search for studies evaluating the effects of hormone therapy in menopausal women with asymptomatic fibroids demonstrated variable effects of hormone therapy on the volume and size of the fibroids. Some studies have demonstrated an increase in size of pre-existing asymptomatic fibroids and formation of new fibroids with higher doses of progestogen in combination therapy. The finding of low resistance index in uterine arteries of women with asymptomatic fibroids is associated with an increased risk of fibroid growth, and thus making the measurement of pulsatility index of uterine arteries a possible screening tool before initiating hormone therapy in menopausal women with fibroids. Although the effect of hormone treatment is variable and statistically insignificant in many cases, the newer selective estrogen receptor modulators having tissue-specific estrogen agonistic and antagonistic actions such as raloxifene have a favorable clinical profile and may be better alternatives in women with asymptomatic fibroids.

Abstract
Hormone replacement therapy (HRT) increases the risk of endometrial and breast cancer. A strategy to reduce this incidence is the use of tibolone (TIB). The aim of this paper was to address the effects of TIB on the central nervous system (CNS). For the present review, MEDLINE (via PubMed), LILACS (via BIREME), Ovid Global Health, SCOPUS, Scielo, and PsycINFO (ProQuest Research Library) electronic databases were searched for the results of controlled clinical trials on peri- and postmenopausal women published from 1990 to September 2016. Also, this paper reviews experimental studies performed to analyze neuroprotective effects, cognitive deficits, neuroplasticity, oxidative stress, and stroke using TIB. Although there are few studies on the effect of this hormone in the CNS, it has been reported that TIB decreases lipid peroxidation levels and improves memory and learning. TIB has important neuroprotective effects that could prevent the risk of neurodegenerative diseases in postmenopausal women as well as the benefits of HRT in counteracting hot flashes, improving mood, and libido. Some reports have found that TIB delays cognitive impairment in various models of neuronal damage. It also modifies brain plasticity since it acts as an endocrine modulator regulating neurotransmitters, Tau phosphorylation, and decreasing neuronal death. Finally, its antioxidant effects have also been reported in different animal models.

Abstract
OBJECTIVE To determine the effects of estrogen therapy on objective sleep quality in insomniac postmenopausal women without severe vasomotor symptoms and/or recognized hot flushes during sleep. Study design Randomized, double-blinded, placebo-controlled trial, parallel design (ClinicalTrials.gov Identifier: NCT01501422). METHODS Forty insomniac postmenopausal women with no severe vasomotor symptoms and/or recognized hot flushes during sleep were randomized into 2 months' treatment with a 50-μg transdermal estradiol patch or placebo. Sleep quality was determined objectively with wrist actigraphy. Sleep efficiency, total sleep time, wake up after sleep onset and number of awakenings were compared before and after treatment. The Insomnia Severity Index (ISI) and Epworth Sleepiness Scale (ESS) questionnaires were used for subjective sleep quality assessment before and after treatment. RESULTS The study showed no significant difference in sleep efficiency improvement between women having estrogen alone or placebo (median 85.7% vs. 85.2%, respectively, p = 0.71). Similarly, sleep quality scores assessed by ISI and ESS were not significantly different. CONCLUSION Estrogen therapy in insomniac postmenopausal women without severe vasomotor symptoms and/or recognized hot flushes during sleep was not found to improve sleep efficiency during the study period.

Abstract
OBJECTIVE To evaluate the efficacy, safety and tolerability of Tibolone use during the menopausal transition (MT). METHODS Sixty-five healthy women aged 40-55 years (48.5 ± 3.5 years) were recruited for a randomized, double-blind controlled trial. Thirty participants were recruited to receive oral Tibolone 2.5 mg/day - Tibolone Group (TG), and 35 participants were assigned to the Placebo Group (PG), which received one capsule of lactose/day. Both groups were treated for 12 consecutive weeks. The Blatt-Kupperman Menopausal Index (KMI) and the Greene Climacteric Scale (GCS) were used. The glycaemic and lipid profiles, biochemical measures of hepatic function and endometrial thickness were measured for safety. A daily registry of complaints related to the treatment was maintained, and anthropometric measures were obtained to assess tolerability. RESULTS A total of 57 women completed the study. After 12 weeks of Tibolone use, the total score and percentage of the KMI and GCS were significantly decreased compared to baseline, which reflected the efficacy of the treatment of climacteric symptoms. The improvement in blood biochemistry, endometrial atrophy and maintenance of the anthropometrical measures reflected the safety of Tibolone use. The absence of serious side effects demonstrated good tolerability for Tibolone use. CONCLUSIONS The results showed good efficacy, tolerability and safety of Tibolone use during the MT.
