Abstract
Endometrial cancer is one the most prevalent gynecological cancers and, unfortunately, has a poor prognosis due to low response rates to traditional treatments. However, the progress in molecular biology and understanding the genetic mechanisms involved in tumor processes offers valuable information that has led to the current classification that describes four molecular subtypes of endometrial cancer. This review focuses on the molecular mechanisms involved in the pathogenesis of endometrial cancers, such as genetic mutations, defects in the DNA mismatch repair pathway, epigenetic changes, or dysregulation in angiogenic or hormonal signaling pathways. The preclinical genomic and molecular investigations presented allowed for the identification of some molecules that could be used as biomarkers to diagnose, predict, and monitor the progression of endometrial cancer. Besides the therapies known in clinical practice, targeted therapy is described as a new cancer treatment that involves identifying specific molecular targets in tumor cells. By selectively inhibiting these targets, key signaling pathways involved in cancer progression can be disrupted while normal cells are protected. The connection between molecular biomarkers and targeted therapy is vital in the fight against cancer. Ongoing research and clinical trials are exploring the use of standard therapy agents in combination with other treatment strategies like immunotherapy and anti-angiogenesis therapy to improve outcomes and personalize treatment for patients with endometrial cancer. This approach has the potential to transform the management of cancer patients. In conclusion, enhancing molecular tools is essential for stratifying the risk and guiding surgery, adjuvant therapy, and cancer treatment for women with endometrial cancer. In addition, the information from this review may have an essential value in the personalized therapy approach for endometrial cancer to improve the patient's life.

Abstract
INTRODUCTION Cancer remains a worldwide threat, having caused almost 10 million deaths in 2020. The American Cancer Society has identified both known and probable carcinogens, including commonly used drugs. The aim of this study is to describe the drugs most frequently reported in the occurrence of cancer. METHODS Among all individual case safety reports (ICSRs) in the global pharmacovigilance database VigiBase, we searched for the 50 most reported drugs with an adverse drug reaction term belonging to the query "Malignant or unspecified tumors" until June 30, 2023. Then, we extracted the disproportionality measurement data, information component (IC), and reporting odds ratio (ROR) in order to assess a disproportionality signal. RESULTS Among all ICSRs in VigiBase, 871,925 contained an ADR belonging to the SMQ "Malignant or unspecified tumors". Ranitidine was the drug with the most reported ADRs related to cancer (n=106,484), followed by lenalidomide (n=13,466), and etanercept (n=8014). The drugs with the highest IC were ranitidine (IC=5.2, 95% confidence interval [95% CI]=5.2-5.2), pioglitazone (1353 ICSRs, IC=4.2, 95% CI=4.2-4.2), and regorafenib (1272 ICSRs, IC=2.8, 95% CI=2.8-2.8). DISCUSSION Our results show that the main pharmacological mechanisms are associated with ranitidine (link with levels of N-nitrosodimethylamine in ranitidine-based drugs), gene-activating drugs (pioglitazone: link with agonist effects on PPAR-γ gene activation), various pharmacological families with immunosuppressive effects (protein kinase inhibitors, immunomodulators, azathioprine, etc.), certain types of protein kinase inhibitors whose oncogenic mechanisms remain unclear (regorafenib, sorafenib, imatinib, ibrutinib, etc.), and hormone antagonists (tamoxifen, letrozole). Special monitoring of patients exposed to these drugs may be required. Further studies are needed to assess the risk with certain drugs in this ranking.

Abstract
PURPOSE Uterine cancer risk is high in breast cancer survivors. Although breast cancer and uterine cancer share some common epidemiological risk factors, association of metabolic syndrome with incident uterine cancer in breast cancer survivors is under-studied. We evaluated the association of metabolic syndrome conditions with second primary uterine cancer in breast cancer survivors. METHODS In this retrospective cohort study, 37,303 breast cancer patients diagnosed between 2008 and 2020 at Kaiser Permanente Southern California, an integrated healthcare system, were included. Data on cancer-related variables, sociodemographic, and clinical variables were extracted from KPSC's Surveillance, Epidemiology, and End Results (SEER)-affiliated cancer registry and electronic health records, as appropriate. Patients were followed from breast cancer diagnosis until 12/31/2021 for incident uterine cancer. Proportional hazards regression was used to report association [HR (95% CI)] between metabolic conditions and uterine cancer. RESULTS More than half (53.1%) of the breast cancer survivors had 1-2 metabolic conditions; 19.4% had 3 + , while 27. 5% had no metabolic conditions. Median time to follow-up was 5.33 years and 185 (0.5%) patients developed second primary uterine cancer. Obesity was associated with an elevated uterine cancer risk in the adjusted model [HR (95% CI) 1.64 (1.20-2.25)]. Having 1-2 metabolic conditions (versus none) was not associated with increased uterine cancer risk [adjusted HR (95% CI) 1.24 (0.85-1.82)]; however, there was an increased uterine cancer risk with 3 + metabolic conditions [adjusted HR (95% CI) 1.82 (1.16-2.87)]. CONCLUSION Although not statistically significant, we found a trend demonstrating greater uterine cancer risk by increasing numbers of metabolic syndrome conditions in breast cancer survivors.

Abstract
INTRODUCTION breast cancer is the cancer with the highest incidence in women in Brazil, representing 29.7% of all cancers. More than two thirds of women with breast cancer show expression for hormone receptors, and in these cases, hormone therapy with tamoxifen is indicated, which may represent a risk factor for the development of endometrial cancer (four-fold greater relative risk). OBJECTIVE this study aimed to evaluate the association of tamoxifen and the development of endometrial disturbances and to assess possible other associated risk factors. PATIENTS AND METHOD a total of 364 breast cancer patients were evaluated, 286 who used tamoxifen and 78 who did not use this hormone therapy. Results: patients who used tamoxifen had a mean follow-up time of 51.42 months similar to those without hormone therapy (p=0.081). A total of 21 (7.3%) women who used tamofixen and no cases among women without hormone therapy presented endometrial changes during follow-up (p=0.01). Despite information regarding obesity was available for only 270 women, obesity was also significantly associated with the development of endometrial changes (p=0.008). CONCLUSION furthermore, the association between tamofixen and endometrial changes remained significant (p=0.039) after adjusting for obesity.

Abstract
BACKGROUND Worse prognosis of endometrial cancers (EC) in tamoxifen-treated women compared to non-tamoxifen-treated women been proposed. The relationship between tamoxifen treatment of breast cancer (BC) and the risk of EC is controversial and there is no agreement between publication results on this issue (the answer to all comments provided in the page 2 of manuscript). The aim of this study is investigation the association between tamoxifen treatment and the risk of EC in patients with BC. METHODS AND RESULTS We conducted a comprehensive search with related keywords in MEDLINE/PubMed, SCOPUS, and Web of Science databases until April 16, 2022. Random-effects model (DerSimonian and Laird) was used to pool risk ratios (RRs) with 95% confidence intervals (CIs) of EC. Dose, cumulative dose, and duration-response analysis were performed in linear and non-linear states. Twenty-six studies reported a relation between tamoxifen treatment and risk of EC in patients with BC. Results showed a direct relationship between tamoxifen use and EC (RR: 2.03, 95% CI: 1.68-2.45; I2:76%). By increase the age of participants, the risk of EC was decrease (coef = -.0206), although this was not statistically significant (p = .37). Linear dose-response model indicated a direct significant association between dose and duration use of tamoxifen and EC (dose: exe(b) = 1.019, p = .001; duration: exe(b) = 1.014, p = .001). Non-linear dose-response analysis confirmed linear analysis. CONCLUSION This study highlights that tamoxifen use is a significant risk factor related to the incidence of EC in patients with BC.

Abstract
Background Tamoxifen has been successfully administered as adjunctive therapy for breast cancer. However, the effect of tamoxifen as an estrogen agonist and antagonist can cause pathological changes in the uterus. The agonist effect may stimulate endometrial proliferation leading to endometrial polyps, hyperplasia, and, rarely, endometrial cancer. Objective We present the case of tamoxifen-treated breast cancer case to better understand one of the most serious consequences, endometrial cancer. Case presentation A 37-year-old woman came to our centre with complaints of abnormal vaginal bleeding. She has diagnosed with grade I infiltrative ductal carcinoma in 2018, with primary complaints of right breast mass and axillary lymphadenopathy. During this period, adjuvant chemotherapy was given tamoxifen 20 mg once daily. There were no complaints or relapses at a six-month follow-up over three years. In the fourth year, the patient complained of vaginal bleeding. A vaginal biopsy was performed, and the results showed low-grade endometrioid-type endometrial carcinoma. Total hysterectomy and bilateral salpingo-oophorectomy were performed with the resultant mass of up to half of the myometrial lining with metastatic negative parallax lymph nodes. Conclusion Following tamoxifen therapy, endometrial cancer is more likely to occur in patients. Patients who experience irregular vaginal hemorrhage should have hysteroscopy or uterine ultrasound performed, and if the cause is unknown, a biopsy should be performed.

Abstract
RESUMO Introdução: o câncer da mama é o câncer de maior incidência no sexo feminino no Brasil, representando 29,7% de todos os cânceres. Mais de dois terços das mulheres com câncer da mama apresentam expressão para receptores hormonais, estando, nestes casos, indicada a terapia hormonal com tamoxifeno, que pode representar fator de risco para o desenvolvimento do câncer do endométrio (risco relativo quatro vezes maior). Objetivo: este trabalho teve como objetivo avaliar a associação entre o uso de tamoxifeno e o desenvolvimento de distúrbios endometriais bem como eventuais outros fatores associados. Pacientes e método: Estudo de coorte retrospectivo de 364 pacientes com câncer da mama, das quais 286 utilizaram tamoxifeno e 78 não utilizaram esta hormonioterapia. Resultados: pacientes que usaram tamoxifeno tiveram um seguimento médio de 51,42 meses, semelhante àquelas sem terapia hormonal (p=0,081). Um total de 21 (7,3%) mulheres que usaram tamofixeno e nenhuma mulher sem terapia hormonal apresentaram alterações endometriais durante o seguimento (p=0,01). Nas 270 mulheres que tinham informação sobre obesidade, esta se associou significantemente com o desenvolvimento de alterações endometriais (p=0,008). A associação entre tamofixeno e alterações endometriais permaneceu significante (p=0,039) após ajustar para interação com obesidade. Conclusão: o uso de tamoxifeno no tratamento do câncer da mama esteve associado ao maior risco para desenvolvimento de alterações endometriais especialmente quando associado à obesidade.

Abstract
Abstract
Background
Despite benefits of endocrine therapy (ET) for patients with hormone-receptor (HR)-positive breast cancer, many patients do not initiate or discontinue ET against recommendations.
Methods
We identified variables associated with ET initiation and continuation, analyzing pooled data from two longitudinal studies at a National Cancer Institute comprehensive cancer center in St. Louis, Missouri. The sample included 533 women with newly diagnosed, non-metastatic, HR-positive breast cancer who completed interviews at enrollment and 6, 12, and 24 months after definitive surgical treatment. Logistic regression models estimated the adjusted odds ratio and 95% confidence interval (aOR [95% CI]) for each of self-reported ET initiation by the 12-month interview and continuation for ≥12 months by the 24-month interview in association with self-reported diabetes, elevated depressed mood, menopausal-symptom severity and obesity, adjusting for race, age, insurance status, chemotherapy, and radiation therapy.
Results
Overall, 81.4% (434/533) of patients initiated ET, and 86.5% (371/429) continued ET ≥12 months. Patients with diabetes had lower odds of initiating ET (0.50 [0.27-0.91]). Patients reporting greater menopausal-symptom severity had lower odds of continuing ET (0.72 [0.53-0.99]).
Conclusion
Efforts to increase ET initiation among patients with diabetes and better manage severe menopausal symptoms among ET users might promote ET continuation.

Abstract
IMPORTANCE The association of tamoxifen use with the risk of uterine diseases, such as endometrial cancer, in premenopausal women with breast cancer remains controversial. However, many studies have reported an increased risk of uterine disease among postmenopausal tamoxifen users. OBJECTIVE To investigate the association of tamoxifen use with the risk of endometrial cancer and other uterine diseases in premenopausal women with breast cancer. DESIGN, SETTING, AND PARTICIPANTS A nationwide, population-based, retrospective longitudinal cohort study with an 18-year study period was conducted using data obtained from the Korean National Health Insurance Service. Participants included premenopausal women aged 20 to 50 years with breast cancer diagnoses between January 2003 and December 2018. Data were analyzed from April to December 2021. EXPOSURES Tamoxifen treatment. MAIN OUTCOMES AND MEASURES The incidence of uterine diseases, including endometrial cancer, hyperplasia, polyps, and other uterine cancers, was identified in the study cohort using insurance claim codes. The incidence of uterine diseases per 1000 person-years was compared between women receiving tamoxifen and those not treated with adjuvant hormone therapy. Multivariable Cox proportional hazard regression analysis was performed to determine the risk of each uterine disease. RESULTS Among 78 320 female participants with a mean (SD) age of 42.1 (6.1) years, 34 637 (44.2%) were categorized into the tamoxifen group and 43 683 (55.8%) were categorized into the control group. Among tamoxifen users, during the mean (SD) follow-up duration of 6.13 (4.15) years, the incidence of newly diagnosed endometrial polyps was 20.13 cases per 1000 person-years, that of endometrial hyperplasia was 13.49 cases per 1000 person-years, that of endometrial cancer was 2.01 cases per 1000 person-years, and that of other uterine cancers was 0.45 cases per 1000 person-years. The risk of endometrial cancer was higher in the tamoxifen group than in the control group (hazard ratio, 3.77; 95% CI, 3.04-4.66) after adjusting for age, body mass index, history of diabetes, hypertension, dyslipidemia, polycystic ovary syndrome, gonadotropin-releasing hormone agonist treatment, and trastuzumab treatment. CONCLUSIONS AND RELEVANCE In this longitudinal cohort study, premenopausal Korean women with breast cancer who received tamoxifen as adjuvant hormone therapy had a significantly increased risk of endometrial hyperplasia, polyps, carcinoma, and other uterine cancers compared with those who were not treated with adjuvant hormone therapy. These findings suggest that clinicians should consider the risk of uterine disease among tamoxifen users, including premenopausal women.

Conservative Management of Atypical Endometrial Hyperplasia and Early Endometrial Cancer in Childbearing Age Women. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58091256.

Abstract
Total hysterectomy and bilateral adnexectomy is the standard treatment for atypical endometrial hyperplasia and early-stage endometrial cancer. However, the recommended surgical treatment precludes future pregnancy when these conditions are diagnosed in women in their fertile age. In these patients, fertility-sparing treatment may be feasible if the desire for childbearing is consistent and specific conditions are present. This review summarizes the available evidence on fertility-sparing management for atypical endometrial hyperplasia and early-stage endometrial cancer. Historically, oral progestins have been the mainstay of conservative management for atypical endometrial hyperplasia and stage IA endometrioid endometrial cancer with no myometrial invasion, although there is no consensus on dosage and treatment length. Intrauterine progestin therapy has proved a valid alternative option when oral progestins are not tolerated. GnRH analogs, metformin, and hysteroscopic resection in combination with progestins appear to increase the overall efficacy of the treatment. After a complete response, conception is recommended; alternatively, maintenance therapy with strict follow-up has been proposed to decrease recurrence. The risk of disease progression is not negligible, and clinicians should not overlook the risk of hereditary forms of the disease in young patients, in particular, Lynch syndrome. Hysterectomy is performed once the desire for childbearing desire has been established. The conservative management of atypical endometrial hyperplasia and early-stage endometrial cancer is feasible, provided a strong desire for childbearing and permitting clinical–pathological conditions. However, patients must be aware of the need for a strict follow-up and the risk of progression with a possible consequent worsening of the prognosis. More homogenous and well-designed studies are necessary to standardize and identify the best treatment and follow-up protocols.

Abstract
The mammary gland is closely related to the female reproductive system in many aspects, affecting the whole gynecological system. Breast cancer (BC) is the most common malignancy in women and associated with considerable negative effects. Due to various factors including co-pathogenic genetic mutations, environment factors, lifestyle, behavioral factors, treatment regimens and in-creased survival of patients with BC, there is an increased probability of developing additional primary gynecologic cancers such as ovarian cancer (OC), endometrial cancer (EC), and cervical cancer (CC). More and more studies have been conducted in recent years. Multiple primary cancers (MPCs), also known as multiple primary malignancies, refers to two or more different primary cancers in the same patient occurring in the same or different organs or tissues. The pathogenesis of multiple primary cancers is complex and has a negative effect on the prognosis and survival of patients. This review discusses the common types of BC-associated MPCs, namely, BC associated with OC, BC associated with EC and BC associated with CC, as well as risk factors, pathogenesis, treatment, and prognosis of MPCs associated with breast and gynecologic cancers. It provides new intervention and treatment ideas for patients with BC-associated MPCs to improve quality of life and prognosis.

Abstract
The long-term administration of tamoxifen to estrogen receptor α (ERα)-positive breast cancer patients is an established treatment that reduces mortality and recurrence. However, resistance to tamoxifen and an increased risk of endometrial cancer may occur; therefore, the mechanisms by which tamoxifen causes these adverse effects warrant further study. Tamoxifen has been shown to activate mitogen-activated protein kinase (MAPK) in an ERα-independent manner; therefore, we investigated its effects on the MAPK-mediated non-canonical activation of EphA2, a critical event regulating cell migration. Tamoxifen at slightly higher concentrations induced the rapid phosphorylation of EphA2 at Ser-897 via the MAPK/extracellular signal-regulated kinase (ERK) kinase (MEK)-ERK-ribosomal S6 kinases (RSK) pathway in HeLa cells. In addition, tamoxifen significantly enhanced the migration ability of ERα-negative MDA-MB-231 breast cancer cells in RSK- and EphA2-dependent manners. Phosphorylated EphA2 was internalized and re-localized to the plasma membrane, including lamellipodia, in an RSK-dependent manner. Collectively, the present results provide novel insights into the tumor-promoting activity of tamoxifen.

Hormonal Therapy for Gynecological Cancers: How Far Has Science Progressed toward Clinical Applications? Cancers (Basel) 2022; 14:cancers14030759. [PMID: 35159024 PMCID: PMC8833573 DOI: 10.3390/cancers14030759] [Citation(s) in RCA: 31] [Impact Index Per Article: 15.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2021] [Revised: 01/27/2022] [Accepted: 01/30/2022] [Indexed: 02/01/2023] Open
Abstract
Simple Summary The most common therapies for severe and recurrent gynecological cancers are hormone therapy and chemotherapy, and responsiveness to therapy is a key component in prognosis and survivability. Hormone therapy has recently been demonstrated to be an excellent cancer treatment approach. Hormone treatment for gynecological cancers is taking drugs that decrease hormone levels or impede their biological activity, halting or slowing cancer progression. Hormone therapy works by suppressing the multiplication of cancer cells triggered by hormones. Hormonal therapy, such as progestogens or tamoxifen, is frequently recommended for patients with hormone-sensitive recurrent or metastatic gynecological cancers, but response rates and therapeutic effects are inconsistent. Therefore, we discuss the pathogenesis of gynecological malignancies from the hormonal landscape and the use of hormonal therapies toward clinical applications. Abstract In recent years, hormone therapy has been shown to be a remarkable treatment option for cancer. Hormone treatment for gynecological cancers involves the use of medications that reduce the level of hormones or inhibit their biological activity, thereby stopping or slowing cancer growth. Hormone treatment works by preventing hormones from causing cancer cells to multiply. Aromatase inhibitors, anti-estrogens, progestin, estrogen receptor (ER) antagonists, GnRH agonists, and progestogen are effectively used as therapeutics for vulvar cancer, cervical cancer, vaginal cancer, uterine cancer, and ovarian cancer. Hormone replacement therapy has a high success rate. In particular, progestogen and estrogen replacement are associated with a decreased incidence of gynecological cancers in women infected with human papillomavirus (HPV). The activation of estrogen via the transcriptional functionality of ERα may either be promoted or decreased by gene products of HPV. Hormonal treatment is frequently administered to patients with hormone-sensitive recurring or metastatic gynecologic malignancies, although response rates and therapeutic outcomes are inconsistent. Therefore, this review outlines the use of hormonal therapy for gynecological cancers and identifies the current knowledge gaps.

Abstract
Background Extending endocrine therapy from 5 to 10 years is recommended for women with invasive estrogen receptor (ER)‐positive breast cancers. We evaluated the benefits and harms of the five additional years of therapy. Methods An established Cancer Intervention and Surveillance Network (CISNET) model used a lifetime horizon with national and clinical trial data on treatment efficacy and adverse events and other‐cause mortality among multiple birth cohorts of U.S. women ages 25–79 newly diagnosed with ER+, non‐metastatic breast cancer. We assumed 100% use of therapy. Outcomes included life years (LYs), quality‐adjusted life years (QALYs), and breast cancer mortality. Results were discounted at 3%. Sensitivity analyses tested a 15‐year time horizon and alternative assumptions. Results Extending tamoxifen therapy duration among women ages 25–49 reduced the lifetime probability of breast cancer death from 11.9% to 9.3% (absolute difference 2.6%). This translates to a gain of 0.77 LYs (281 days)/woman (undiscounted). Adverse events reduce this gain to 0.44 QALYs and after discounting, gains are 0.20 QALYs (73 days)/woman. Extended aromatase inhibitor therapy in women 50–79 had small absolute benefits and gains were offset by adverse events (loss of 0.06 discounted QALYs). There were greater gains with extended endocrine therapy for women with node‐positive versus negative cancers, but only women ages 25–49 and 50–59 had a net QALY gain. All gains were reduced with less than 100% treatment completion. Conclusion The extension of endocrine therapy from 5 to 10 years modestly improved lifetime breast cancer outcomes, but in some women, treatment‐related adverse events may outweigh benefits.

Abstract
Background: Our study aimed to assess the risk of endometrial pathologies after tamoxifen and aromatase inhibitors (AIs) adjuvant treatment for female breast cancer patients treated at Sultan Qaboos University Hospital in Oman. Materials and Methods: A total of 457 patients diagnosed with estrogen positive breast cancer between January 2011 and December 2018 were screened. Two hundred and four patients met the inclusion criteria, and their detailed clinicopathological and endometrial surveillance data were collected from their electronic health records. Results: All patients underwent endometrial assessment during tamoxifen or letrozole therapy. The mean diagnostic age of breast cancer patients is 43.6 years, ranging from 27-84 years. Eighty-three percent of those patients are premenopausal, and 17% are postmenopausal. The mean tamoxifen use duration was 33 months. The majority of patients, 123 (60.3%), have had tamoxifen for three years or less, 47 (23.1%) for 3-5 years, and only 22 (10.8%) were on tamoxifen for more than five years. Increased endometrial thickness was reported in 8% of the premenopausal and 14% of the postmenopausal group. Other endometrial pathologies that were detected are inactive endometrium three (1.47%), atrophic endometrium three (1.47%), serous carcinoma one (0.50%), endometrial cancer two (0.98%), and chronic endometritis one (0.50%), which were not significantly associated with tamoxifen or letrozole therapy duration. Two patients have developed endometrial cancer, and both are postmenopausal and > 60 years old. Conclusions: Tamoxifen and letrozole did not increase the risk of endometrial cancer in premenopausal patients. Breast Cancer (BC) patients on tamoxifen or letrozole might need a pre-treatment endometrial evaluation and explanation of alarming symptoms to guide further endometrial surveillance.

Abstract
Granulosa cell tumors (GCTs) can have a wide variety of appearances on magnetic resonance imaging (MRI), ranging from entirely solid to multilocular cystic, suggesting that GCTs undergo remarkable morphological changes during growth. These temporal changes in MRI appearance of individual GCTs have not been documented. A 54-year-old asymptomatic postmenopausal woman was referred to our department for a small ovarian mass. This 3-cm solid mass showed high intensity on diffusion-weighted MRI and low intensity on apparent diffusion coefficient mapping. Close clinical follow-up was recommended, but she did not return to our hospital until the age of 63, when she was referred for a large ovarian tumor. MRI showed a 15-cm multilocular cyst containing a solid component with hemorrhaging. Postoperative diagnosis was adult GCT (AGCT). These temporal changes demonstrate a possible reason why GCTs can have such a wide range of MRI appearance. This knowledge might promote accurate preoperative diagnosis of AGCTs.

Abstract
Simple Summary Tamoxifen, an antiestrogen, is a potent drug to treat and prevent hormone dependent breast cancer. As it has low toxicity and is widely available, tamoxifen has become one of the most frequently prescribed anticancer drugs worldwide. A major side effect of tamoxifen is to increase the risk of uterine corpus cancer (endometrial cancer). This happens after long-term (>2 years) application, especially in postmenopausal women with preexisting pathologies in the uterus. On the other hand, tamoxifen is an efficacious treatment for certain forms of advanced endometrial cancer, thus making it a Janus-headed drug that can support the development of endometrial cancer on one hand and be used as a remedy for this disease on the other. This article reviews the clinical data on these controversial effects of tamoxifen and the possible explanations. Abstract Tamoxifen is a selective estrogen receptor modulator used for the treatment and prevention of estrogen receptor (ER)—positive breast cancer. However, tamoxifen increases the risk of endometrial cancer (EC) by about 2–7 fold, and more aggressive types of EC with poor prognoses are observed in tamoxifen users. On the other hand, tamoxifen is an efficacious treatment for advanced or recurrent EC with low toxicity. The differential agonistic or antagonistic effects of tamoxifen on ERα are explained by the tissue-specific expression profiles of co-activators and co-repressors of the receptor. The estrogen-agonistic effect of tamoxifen in endometrial cancers can also be explained by the expression of G-protein coupled estrogen receptor 1 (GPER-1), a membrane-bound estrogen receptor for which tamoxifen and other “antiestrogens” are pure agonists.

Abstract
PURPOSE Epidemiological evidence on the risk factors for uterine/endometrial cancer in breast cancer (BCa) survivors is limited and inconsistent. Therefore, we critically reviewed and summarized available evidence related to the risk factors for uterine/endometrial cancer in BCa survivors. METHODS We conducted a literature search through PubMed, Web of Science Core Collection/Cited Reference Search, as well as through manual searches of the bibliographies of the articles identified in electronic searches. We included in this review studies that were published up to November 30, 2018 that were accessible in full-text format and were published in English. RESULTS Of the 27 eligible studies, 96% had > 700 participants, 74% were prospective cohorts, 70% originated outside of the US, 44% reported as having pre-/postmenopausal women, and 26% reported having racially heterogeneous populations. Risk factors positively associated with uterine/endometrial cancer risk among BCa survivors included age at BCa diagnosis > 50 years, African American race, greater BMI/weight gain, and Tamoxifen treatment. For other lifestyle, reproductive and clinical factors, associations were either not significant (parity) or inconsistent (HRT use, menopausal status, smoking status) or had limited evidence (alcohol intake, family history of cancer, age at first birth, oral contraceptive use, age at menopause, comorbidities). CONCLUSION We identified several methodological concerns and limitations across epidemiological studies on potential risk factors for uterine/endometrial cancer in BCa survivors, including lack of details on uterine/endometrial cancer case ascertainment, varying and imprecise definitions of important covariates, insufficient adjustment for potential confounders, and small numbers of uterine/endometrial cancer cases in the overall as well as stratified analyses. Based on the available evidence, older age and higher body weight measures appear to be a shared risk factor for uterine/endometrial cancer in the general population as well as in BCa survivors. In addition, there is suggestive evidence that African American BCa survivors have a higher risk of uterine/endometrial cancer as compared to their White counterparts. There is also evidence that Tamoxifen contributes to uterine/endometrial cancer in BCa survivors. Given limitations of existing studies, more thorough investigation of these associations is warranted to identify additional preventive strategies needed for BCa survivors to reduce uterine/endometrial cancer risk and improve overall survival.

Abstract
Fluorene-9-bisphenol (BHPF), a new derivative of bisphenol A (BPA), has been introduced for treatment with estrogen-related tumors, such as endometrial cancer. This study investigated the potential mechanism underlying the action of BHPF against endometrial cancer in vitro. We used the cell counting kit-8 (CCK8) method on Ishikawa cells to screen sub-lethal doses of BHPF and established the optimal concentration at which BHPF influenced the proliferation of Ishikawa cells. Effect of BHPF on cell migration and invasion was investigated by cell scratch assay and transwell assay, respectively. Expression levels of epithelial-mesenchymal transition (EMT)-related proteins were detected by Western blot analysis. BHPF was found to inhibit the proliferation of Ishikawa cells, whose migration and invasion abilities were also reduced. Western blot indicated that BHPF can significantly inhibit the EMT process of Ishikawa cells by blocking transforming growth factor-β (TGF-β) signaling pathway. This is the first report of the effect of BHPF on the biological behavior of endometrial cancer cells and its inhibition of endometrial cancer progression by repressing both endometrial cell proliferation and epithelial-mesenchymal transition, hence suggesting it as a novel anti-cancer drug. Graphical abstract Schematic representation of the molecular basis underlying BHPF treatment. BHPF repressed the EMT process by regulating EMT-related genes, such as E-cadherin, N-cadherin, and vimentin as well as the TGF-β signaling pathway-related genes, including p-Smad2/3 and slug, in a BHPF-dependent manner.

Abstract
Purpose Breast cancer is a common disease with a relatively good prognosis. Therefore, understanding the spectrum of diseases and mortality among breast cancer patients is important, though currently incomplete. We systematically examined the incidence and mortality of all diseases following a breast cancer diagnosis, as well as the sequential association of disease occurrences (trajectories). Methods In this national cohort study, 57,501 breast cancer patients (2001–2011) were compared to 564,703 matched women from the general Swedish population and followed until 2012. The matching criteria included year of birth, county of residence, and socioeconomic status. Based on information from the Swedish Patient and Cause of Death Registries, hazard ratios (HR) were estimated for disease incidence and mortality. Conditional logistic regression models were used to identify disease trajectories among breast cancer patients. Results Among 225 diseases, 45 had HRs > 1.5 and p < 0.0002 when comparing breast cancer patients with the general population. Diseases with highest HRs included lymphedema, radiodermatitis, and neutropenia, which are side effects of surgery, radiotherapy, and chemotherapy. Other than breast cancer, the only significantly increased cause of death was other solid cancers (HR = 1.16, 95% CI = 1.08–1.24). Two main groups of disease trajectories were identified, which suggest menopausal disorders as indicators for other solid cancers, and both neutropenia and dorsalgia as diseases and symptoms preceding death due to breast cancer. Conclusions While an increased incidence of other diseases was found among breast cancer patients, increased mortality was only due to other solid cancers. Preventing death due to breast cancer should be a priority to prolong life in breast cancer patients, but closer surveillance of other solid cancers is also needed.

Mohamed HH, Ibrahim Sokkar M, Afifi AM, Saad AM, Albarouki S, Al-Husseini MJ. Does a history of malignancy impact the survival of a subsequent endometrial adenocarcinoma? Should clinical trials eligibility criteria be revisited? J OBSTET GYNAECOL 2019; 40:233-239.

Abstract
We aimed at finding the impact of prior malignancies on the survival of patients with endometrial adenocarcinoma using SEER database (from 1973 to 2014). We identified 127,988 patients who were diagnosed with endometrial adenocarcinoma (6485 had a prior malignancy), and we compared the overall and cancer-specific survival based on the presence or absence of a prior malignancy and the latency period between the two diagnoses using Kaplan-Meier test and Cox models. Adjusted cox models showed that a history of a prior malignancy neither affected the overall survival nor the cancer-specific survival of stage IV cases in all latency groups except the one diagnosed within 1 year of the first cancer. Therefore, there is no rational explanation for excluding stage IV endometrial adenocarcinoma patients with a prior malignancy from clinical trials except for the group that was diagnosed with endometrial adenocarcinoma within 1 year from the first cancer.Impact statementWhat is already known on this subject? Not enough evidence is found on the impact of prior malignancies on the survival of patients with subsequent endometrial adenocarcinoma.What do the results of this study add? History of a prior malignancy neither affects the overall survival of stage IV endometrial adenocarcinoma nor the cancer-specific survival. Only patients who had their second malignancy diagnosed within one year of the first malignancy should be excluded from clinical trials, while patients diagnosed within one to five years of the first cancer should be encouraged to enrol in clinical trials as they have an enhanced survival than patients without a history of malignancy.What are the implications of these findings for clinical practice and/or further research? We recommend that future researchers should consider including the aforementioned group of patients in their trials to achieve more accurate results and in order not to strip the patients of potential therapeutic benefits of enrolling in clinical trials.

Chu SC, Hsieh CJ, Wang TF, Hong MK, Chu TY. Younger tamoxifen-treated breast cancer patients also had higher risk of endometrial cancer and the risk could be reduced by sequenced aromatase inhibitor use: A population-based study in Taiwan. Tzu Chi Med J 2019; 32:175-180. [PMID: 32269951 PMCID: PMC7137368 DOI: 10.4103/tcmj.tcmj_17_19] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/15/2019] [Revised: 03/21/2019] [Accepted: 04/06/2019] [Indexed: 01/13/2023] Open
Abstract
Objective: Previous Western studies reported that older (≥50 years) breast cancer survivors with tamoxifen treatment had higher risk of endometrial cancer. This study aims to disclose whether younger (<50 years) tamoxifen-treated breast cancer patients also had higher risk of endometrial cancer and to examine whether sequenced aromatase inhibitor (AI) use could reduce the risk. Materials and Methods: A population-based cohort of 39,216 newly diagnosed breast cancer patients was identified from Taiwan National Health Insurance Database from 1999 to 2012. The risk of endometrial cancer in nonusers (n = 14,588), tamoxifen-only (n = 19,302), and sequenced AI (n = 5326) users was compared with Cox regression analysis and was adjusted with age, diabetes, hypertension, and chemotherapy. Results: During the 14-year study period, 133 patients were diagnosed with subsequent endometrial cancers. Compared with nonusers, tamoxifen-only users had higher risk of endometrial cancer (14-year incidence 1.7% vs. 0.3%; adjusted hazard ratio [HR] 3.90; 95% confidence interval [CI], 2.37–6.42). This was observed in both older (≥50 years) and younger (40–50 years) age groups. Adjusted HR (95% CI) for the latter was 3.74 (1.65–8.48). This risk persisted after cessation of tamoxifen use. The risk of endometrial cancer was lower in sequenced AI when compared with tamoxifen-only users (adjusted HR 0.43; 95% CI, 0.25–0.72). Conclusions: Not only patients ≥50 years but also younger (40–49 years) patients with tamoxifen treatment had higher risk of subsequent endometrial cancer in this nation-wide cohort. We suggest regular gynecologic monitoring not only during active use but also during follow-up phase. Sequenced AI use may reduce the risk of endometrial cancer in tamoxifen-treated breast cancer patients.

Abstract
Due to the anatomical continuity of the uterine cavity with the cervix, genomic exploitation of material from routine Pap smears and other noninvasive sampling methods represent a unique opportunity to detect signs of disease using biological material shed from the upper genital tract. Recent research findings offer a promising perspective in the detection of endometrial cancer, but certain questions need to be addressed in order to accelerate the implementation of novel technologies in a routine screening or clinical setting. We discuss here new perspectives on detection of endometrial cancer using genomic and other biomarkers in minimally invasive sampling methods with a special focus on public health classic screening criteria, highlighting current gaps in knowledge.

Abstract
AIM A rapid UPLC-MS/MS method for the determination of tamoxifen (TAM), N-desmethyltamoxifen, 4-hydroxytamoxifen and endoxifen in human plasma was validated, after a simple protein precipitation. MATERIALS AND METHODS The analysis was achieved on a C18 analytical column, using a gradient elution with a mobile phase of water and acetonitrile for 4.5 min. RESULTS The validated method demonstrated good linearity between 1 and 500 ng/ml for TAM and N-desmethyltamoxifen; between 0.2 and 100 ng/ml for endoxifen and between 0.1 and 50 ng/ml for 4-hydroxytamoxifen. The method also provided satisfactory results in terms of within day and between day imprecisions and accuracy, and also in terms of time stability and specificity. CONCLUSION The method is applied routinely for TAM monitoring from patients undergoing therapy.

Abstract
Retrospective evidence drawn from real-world experience of a medicine's use outside its labelled indication is one of a number of techniques used in drug repurposing (DRP). Relying as it does on large numbers of real incidences of human experience, rather than individual case reports with limited statistical support, preclinical experiments with poor translatability or in silico associations, which are early-stage hypotheses, it represents the best validated form of DRP. Cancer is the most frequent of such DRP examples (e.g. aspirin in pancreatic cancer, hazard ratio = 0.25). This approach can be combined with pathway analysis to provide first-in-class treatments for complex diseases. Alternatively, it can be combined with prospective preclinical studies to uncover a validated mechanism for a new indication, after which a repurposed molecule is chemically optimized.

Pir2/Rnf144b is a potential endometrial cancer biomarker that promotes cell proliferation. Cell Death Dis 2018; 9:504.

Abstract
Endometrial cancer is one of the most common gynaecological cancers in developed countries. Its incidence has increased 20% over the last decade and the death rate has increased >100% over the past two decades. Current models for prediction of prognosis and treatment response are suboptimal, and as such biomarkers to support clinical decision-making and contribute to individualised treatment are needed. In this study, we show that the E3-ubiquitin ligase PIR2/RNF144B is a potential targetable biomarker in endometrial cancer. At transcript level, it is expressed both in normal endometrium and tumour samples, but at protein level, it is expressed in tumours only. By using endometrial cancer cell lines, we demonstrated that PIR2/RNF144B is stabilised via phosphorylation downstream of GSK3β and this is necessary for the proliferation of endometrial cancer cells, in the absence of oestrogenic growth stimuli. Here, inactivation of GSK3β activity is associated with loss of PIR2/RNF144B protein and consequent inhibition of cell proliferation. Our results, therefore, substantiate PIR2/RNF144B as a novel candidate for targeted therapy in endometrial cancer.

Abstract
BACKGROUND Previous studies have suggested that metformin may be useful for preventing and treating endometrial cancer (EC), while the results have been inconsistent. This systematic review and meta-analysis aimed to investigate the association between metformin use and risk and prognosis of patients with EC. METHODS PubMed, Embase, and the Cochrane Library databases were searched for observational studies evaluating the effect of metformin on EC prevention or treatment. The odds ratio (OR) was used for analyzing risks, and the hazard ratio (HR) was used for analyzing survival outcomes. A random-effects model was used for data analysis. RESULTS Seven studies reported data on EC risk. The pooled results suggested that metformin was not significantly associated with a lower risk of EC [OR = 1.05, 95% confidence interval (CI) 0.82-1.35, P = 0.70]. For patients with diabetes, metformin showed no advantage in reducing the EC risk compared with other interventions (OR = 0.99, 95% CI 0.78-1.26, P = 0.95). Further, seven studies were included for survival analysis. The pooled data showed that metformin could significantly improve the overall survival of patients with EC (HR = 0.61, 95% CI 0.48-0.77, P < 0.05) and reduce the risk of EC recurrence (OR = 0.50, 95% CI 0.28-0.92, P < 0.05) Finally, we noted metformin was associated with significantly improving the overall survival of EC patients among diabetes (HR = 0.47; 95%CI 0.33-0.67, P < 0.05). CONCLUSIONS This meta-analysis did not prove that metformin was beneficial for preventing EC. However, metformin could prolong the overall survival of patients with EC and reduce their risk of cancer relapse.

Abstract
The incidence of endometrial cancer is increasing, and the age of onset is younger than in prior years. Although endometrial cancer still occurs more commonly in older women, for whom the mortality rate is increasing, it also is being diagnosed in younger and younger women. The underlying cause of the increase in incidence is the epidemic of obesity and the resulting hyperinsulinemia. Conservative treatment may be indicated for younger women who wish to retain their fertility. Lifestyle modifications such as diet and exercise can modulate the risk of developing endometrial cancer as well as prevent recurrence and other comorbidities associated with obesity.

Abstract
Purpose Breast cancer survivors have slightly increased the risk of second primary cancers. Breast, colon, uterine, and ovarian cancers are common secondary cancers in breast cancer survivors. In this study, we assessed the development of second primary cancers of breast cancer survivors in Korea. Methods Medical records of patients with breast cancer in 3 tertiary medical institutions were reviewed retrospectively. We evaluated secondary malignancy diagnosed at least 2 months after the breast cancer diagnosis. Based on the International Classification of Disease-9 codes of malignancies, secondary primary breast cancer records were evaluated with person-year adjustment. The standardized incidence ratio (SIR) was assessed using national cancer incidence. Results A total of 3,444 treatment records were included from 3 medical centers. The cumulative incidence of overall second primary cancers was 2.8% (n = 93). The SIR was significantly higher in all sites (1.56; 95% confidence interval [CI], 1.26–1.91), endometrial cancer (5.65; 95% CI, 2.06–12.31), biliary tract cancer (3.96; 95% CI, 1.19–8.60), and thyroid cancer (2.29; 95% CI, 1.67–3.08). Conclusion The incidence of cancer was higher in breast cancer survivors compared to general population. Surveillance of secondary cancer in this group should be recommended individually considering the benefit related to the prognosis of primary breast cancer.

Abstract
BACKGROUND The selective estrogen receptor modulator tamoxifen is now widely used for the treatment and prevention of breast cancer. Tamoxifen use has been associated with a variety of gynecologic problems. Despite the frequency with which hormonal therapy is used for the treatment of breast cancer, limited population-level data are available to describe the occurrence of gynecologic conditions and the use of surveillance testing in women receiving tamoxifen and aromatase inhibitors. OBJECTIVE We performed a population-based analysis among women with breast cancer receiving hormonal therapy with tamoxifen, a drug commonly used in premenopausal and sometimes postmenopausal women, to determine the frequency of gynecologic abnormalities and use of diagnostic and surveillance testing. We compared these findings to women treated with aromatase inhibitors, agents commonly used in postmenopausal women. STUDY DESIGN The MarketScan database was used to identify women diagnosed with breast cancer from 2009 through 2013 who underwent mastectomy or lumpectomy. Women receiving tamoxifen (age <50 vs ≥50 years) were compared to women ≥50 years of age treated with aromatase inhibitors. We examined the occurrence of gynecologic symptoms and diseases (vaginal bleeding, endometrial polyps, endometrial hyperplasia, and endometrial cancer) and gynecologic procedures and interventions (transvaginal ultrasound, endometrial biopsy, hysteroscopy/dilation and curettage, and hysterectomy). Time-dependent analyses were performed to examine symptoms and testing. RESULTS A total of 75,170 women, including 15,735 (20.9%) age <50 years treated with tamoxifen, 13,827 (18.4%) age ≥50 years treated with tamoxifen, and 45,608 (60.7%) age ≥50 years treated with aromatase inhibitors were identified. The cumulative incidence of any gynecologic symptom or pathologic diagnosis during the study period was 20.2%, 12.3%, and 3.5%, respectively (P < .001), while the cumulative incidence of any gynecologic procedure or intervention during the study period was 34.2%, 20.9%, and 9.0%, respectively (P < .0001). Among women without symptoms or pathology, interventions were performed in 20.0%, 11.0%, and 6.8%, respectively (P < .0001). CONCLUSION Compared to women taking aromatase inhibitors, gynecologic symptoms, procedures, and pathology are higher for both premenopausal and postmenopausal women with breast cancer on tamoxifen. Increased efforts to curb use of gynecologic interventions in asymptomatic women are needed.

Abstract
Aromatase is the rate-limiting enzyme in the biosynthesis of estrogens, which play crucial roles on a spectrum of developmental and physiological processes. The biological actions of estrogens are classically mediated by binding to two estrogen receptors (ERs), ERα and ERβ. Encoded by the cytochrome P450, family 19, subfamily A, polypeptide 1 (CYP19A1) gene, aromatase is expressed in a wide variety of tissues, as well as benign and malignant tumors, and is regulated in a pathway- and tissue-specific manner. Overexpression of aromatase, leading to elevated systemic levels of estrogen, is unequivocally linked to the pathogenesis and growth of a number malignancies, including breast, endometrium, and ovarian cancers. Aromatase inhibitors (AIs) are routinely used to treat estrogen-dependent breast cancers in postmenopausal women; however, their roles in endometrial and ovarian cancers remain obscure. While AI therapy is effective in hormone sensitive cancers, they diminish estrogen production throughout the body and, thus, generate undesirable side effects. Despite the effectiveness of AI therapy, resistance to endocrine therapy remains a major concern and is the leading cause of cancer death. Considerable advances, toward mitigating these issues, have evolved in conjunction with a number of histone deacetylase (HDAC) inhibitors for countering an assortment of diseases and cancers, including the aforesaid malignancies. HDACs are a family of enzymes that are frequently dysregulated in human tumors. This chapter will discuss the current understanding of aberrant regulation and expression of aromatase in breast, endometrial, and ovarian cancers, and potential therapeutic strategies for prevention and treatment of these life-threatening diseases.

Abstract
INTRODUCTION The gynaecological toxicity profile of tamoxifen presents a significant burden to the patients and oncologist as tamoxifen-related side effects result in additional investigations, procedures and referrals. Aromatase inhibitor have been shown to result in significant reduction in gynaecological problems, possibly including endometrial cancer. Areas covered: We reviewed the main breast cancer trials, observation or cohort studies investigating tamoxifen or an aromatase inhibitor to report on endometrial adverse events and cancer. Expert commentary: Evidence for an increase in endometrial cancers with tamoxifen in breast cancer treated patients is now very clear. Aromatase inhibitors have shown to have a beneficial effect on the endometrium. There is an important need for further studies to clearly determine the influence of aromatase inhibitors on the endometrial in tamoxifen-naïve women. The effect of aromatase inhibitors on gynaecological problems may have potentially a very important impact in clinical practice.
