Progesterone Enhances Niraparib Efficacy in Ovarian Cancer by Promoting Palmitoleic-Acid-Mediated Ferroptosis. RESEARCH (WASHINGTON, D.C.) 2024; 7:0371.

Abstract
Poly (adenosine 5'-diphosphate-ribose) polymerase inhibitors (PARPi) are increasingly important in the treatment of ovarian cancer. However, more than 40% of BRCA1/2-deficient patients do not respond to PARPi, and BRCA wild-type cases do not show obvious benefit. In this study, we demonstrated that progesterone acted synergistically with niraparib in ovarian cancer cells by enhancing niraparib-mediated DNA damage and death regardless of BRCA status. This synergy was validated in an ovarian cancer organoid model and in vivo experiments. Furthermore, we found that progesterone enhances the activity of niraparib in ovarian cancer through inducing ferroptosis by up-regulating palmitoleic acid and causing mitochondrial damage. In clinical cohort, it was observed that progesterone prolonged the survival of patients with ovarian cancer receiving PARPi as second-line maintenance therapy, and high progesterone receptor expression combined with low glutathione peroxidase 4 (GPX4) expression predicted better efficacy of PARPi in patients with ovarian cancer. These findings not only offer new therapeutic strategies for PARPi poor response ovarian cancer but also provide potential molecular markers for predicting the PARPi efficacy.

Abstract
Combined hormonal contraception (CHC) remains the most widely used contraceptive strategy, particularly in France. While the benefit-risk balance is very beneficial for the majority of women, its use must be cautious in some clinical situations and in particular in women at vascular risk. It is therefore essential to provide information on all the vascular risk factors before prescribing any CHC, regardless of their route of administration. From an oncological point of view, if the use of CHCs is associated with a slight increase in the risk of breast cancer, their potential benefits persist for many years after their discontinuation for the risk of ovarian and endometrial cancer. These benefits counteract largely the risk of breast cancer. Finally, CHCs provide non-contraceptive benefits, especially in clinical situations such as dysmenorrhea or severe endometriosis. Therefore, it is necessary to precisely assess the clinical context of each woman in order to adapt the best contraceptive strategy.

Abstract
Oral contraceptive agents are currently the most popular and one of the most effective methods for preventing pregnancy. The data shows that over 300 million women in the world use contraceptive drugs containing synthetic hormones to avoid an unwanted pregnancy. Their effects may affect other systems, leading to the occurrence of various problems associated with the use of the drug. The aim of the study is to estimate the frequency of prevalence of subjective effects associated with the use of combined hormonal contraception with a predominance of gestagens by young women Surveys were conducted among female students of Wrocław universities from December 2010 to January 2011. They covered 257 women aged statistically 23.58 (SD=2.95). They were divided into three age classes: 19-22, 23-24, 25- 28. The individual age of menarche and the hormonal type of body were determined. Only persons with a gestagenic or estrogenic type of body were qualified for the study. Results: 64.6% of all respondents declared the use of hormonal contraception. Combined agents with a predominance of gestagens constituted 87% in this group. Their use brings both positive (90%) and negative (65%) aspects. The most common positive effects include high contraceptive effectiveness, regulation of menstruation and minimisation of skin problems. The most frequent negative effects include: weight gain, spotting, breast swelling and decreased libido. Surprisingly, the study did not show any correlation between the hormonal type and the occurrence of side effects. There was no significant statistical relationship between the type of hormonal contraception used and the hormonal type.

Abstract
Epithelial ovarian cancer comprises ∼85% of all ovarian cancer cases. Despite acceptance regarding the influence of reproductive hormones on ovarian cancer risk and considerable advances in the understanding of epithelial ovarian carcinogenesis on a molecular level, complete understanding of the biologic processes underlying malignant transformation of ovarian surface epithelium is lacking. Various hypotheses have been proposed over the past several decades to explain the etiology of the disease. The role of reproductive hormones in epithelial ovarian carcinogenesis remains a key topic of research. Primary questions in the field of ovarian cancer biology center on its developmental cell of origin, the positive and negative effects of each class of hormones on ovarian cancer initiation and progression, and the role of the immune system in the ovarian cancer microenvironment. The development of the female reproductive tract is dictated by the hormonal milieu during embryogenesis. Intensive research efforts have revealed that ovarian cancer is a heterogenous disease that may develop from multiple extra-ovarian tissues, including both Müllerian (fallopian tubes, endometrium) and non-Müllerian structures (gastrointestinal tissue), contributing to its heterogeneity and distinct histologic subtypes. The mechanism underlying ovarian localization, however, remains unclear. Here, we discuss the role of reproductive hormones in influencing the immune system and tipping the balance against or in favor of developing ovarian cancer. We comment on animal models that are critical for experimentally validating existing hypotheses in key areas of endocrine research and useful for preclinical drug development. Finally, we address emerging therapeutic trends directed against ovarian cancer.

Abstract
PURPOSE Asian immigrant and Asian American women are less likely to use oral contraceptives (OCs) and tend to rely on low-efficacy methods of contraception. This contraceptive pattern remains poorly understood, in part, because no theory-driven measurement exists to assess psychosocial determinants essential in explaining behaviors related to OC use in this population. The current study aimed to evaluate the psychometric properties of a measure of attitudes and subjective norms toward OC use among Korean American women as a first step to determine whether the measure can be used in this population and, potentially, in other Asian ethnic groups. METHODS The sample consisted of 329 Korean immigrant women living in New York City. The theory of reasoned action guided the development of the measure assessing attitudes and norms. Psychometric evaluation included item analysis, internal consistency estimates of reliability, and construct validity (i.e., factorial, discriminant, and predictive). RESULTS All item-total correlations were above the recommendation of .30. The Cronbach's alpha for the attitudes and subjective norms measure was .88 and .86, respectively. Exploratory factor analyses revealed four interpretable factors, and confirmatory factor analyses confirmed that the factor structures derived from the exploratory factor analyses fit the data well. Discriminant and predictive validity of the measure were also established. CONCLUSIONS The study provides support for the validity and reliability of the measure and its use for determining the degree to which Korean immigrant women intend to use OCs.

Abstract
Background Unintended pregnancy is a public health problem and unmet medical need worldwide. It is estimated that in the year 2012, almost 213 million pregnancies occurred, and the global pregnancy rate decreased only slightly from 2008 to 2012. It was also estimated that 85 million pregnancies (40% of all pregnancies) were unintended and that 38% ended in an unintended birth. Objectives To assess knowledge and attitudes of Latin American (LA) obstetricians and gynecologists (OBGYNs) regarding unintended pregnancies and aspects of combined oral contraceptive (COC) use. Methods A survey was conducted during a scientific meeting about contraception in 2014, in which OBGYNs from 12 LA countries who provide attention in contraception were invited to respond to a multiple-choice questionnaire to assess their knowledge and attitudes regarding unplanned pregnancy and some aspects regarding COC use. Results A total of 210 OBGYNs participated in the study. Their knowledge regarding COC failure was low. The participants reported they believed that their patients habitually forgot to take a pill and that their patients did not know what to do in these situations. They were aware of the benefits of COC use; however, they were less prone to prescribe COCs for the purpose of protecting against ovarian and endometrial cancer, and one-quarter of them had doubts about the association between COC use and cancer risk. Conclusion The interviewed LA OBGYNs showed some flaws in terms of knowledge of COC failure rates and the non-contraceptive benefits and risks of COCs. To adequately counsel their patients regarding COC intake, OBGYNs must be updated regarding all aspects of COC use.

Abstract
Objective To assess the association between condom use and oral contraceptive consumption and the risk of cervical intraepithelial neoplasia (CIN). Methods A cross-sectional study was conducted in Perth clinics. A total of 348 women responded to the structured questionnaire. Information sought included demographic and lifestyle characteristics such as the use of condom for contraception, consumption of oral contraceptive, and duration of oral contraceptive usage. Crude and adjusted odds ratio (OR) and associated 95% confidence interval (CI) were calculated using unconditional logistic regression models and reported as estimates of the relative risk. Results The prevalence of CIN was found to be 15.8%. The duration of oral contraceptive consumption among women with abnormal Papanicolaou (Pap) smear result indicating CIN was significantly shorter than those without abnormal Pap smear result (mean±SD, 5.6±5.2 years vs. 8.2±7.6 years; p=0.002). Comparing to ≤3 years usage, prolonged consumption of oral contraceptive for ≥10 years reduced the risk of CIN (p=0.012). However, use of condom for contraception might not be associated with a reduced risk of CIN after accounting for the effects of confounding factors (adjusted OR, 0.52; 95% CI, 0.05 to 5.11; p=0.577). Conclusion Use of oral contraceptives, but not condoms, for contraception appeared to be inversely associated with CIN. Prolonged use of oral contraceptive demonstrated its benefits of reducing the risk of CIN.

Abstract
Women with polycystic ovary syndrome (PCOS) have a 2.7-fold increased risk for developing endometrial cancer. A major factor for this increased malignancy risk is prolonged exposure of the endometrium to unopposed estrogen that results from anovulation. Additionally, secretory endometrium of some women with PCOS undergoing ovulation induction or receiving exogenous progestin exhibits progesterone resistance accompanied by dysregulation of gene expression controlling steroid action and cell proliferation. Endometrial surveillance includes transvaginal ultrasound and/or endometrial biopsy to assess thickened endometrium, prolonged amenorrhea, unopposed estrogen exposure or abnormal vaginal bleeding. Medical management for abnormal vaginal bleeding or endometrial hyperplasia consists of estrogen-progestin oral contraceptives, cyclic or continuous progestins or a levonorgestrel-releasing (Mirena) intrauterine device. Lifestyle modification with caloric restriction and exercise is appropriate to treat obesity as a concomitant risk factor for developing endometrial disease. An increased risk of ovarian cancer may also exist in some women with PCOS. There are strong data to suggest that oral contraceptive use is protective against ovarian cancer and increases with the duration of therapy. The mechanism of this protection may be through suppression of gonadotropin secretion rather than the prevention of "incessant ovulation". There is no apparent association of PCOS with breast cancer, although the high prevalence of metabolic dysfunction from obesity is a common denominator for both conditions. Recent data suggest that the use of metformin may be protective for both endometrial and breast cancer. There are insufficient data to evaluate any association between PCOS and vaginal, vulvar and cervical cancer or uterine leiomyosarcoma.

Abstract
Objective To investigate the association between reproductive factors and the risk of ovarian cancer among southern Chinese women. Methods A hospital-based case-control study was undertaken in Guangzhou, Guangdong Province, between 2006 and 2008. A structured questionnaire was used to obtain information on parity, oral contraceptive use and other reproductive factors in a sample of 500 incident ovarian cancer patients and 500 controls (mean age, 59 years). Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using unconditional logistic regression models. Results High parity was inversely associated with ovarian cancer, with an adjusted OR 0.43 (95% CI, 0.30 to 0.62) for women who had given birth to 3 or more children compared to women who had given no more than one birth. Ever use of oral contraceptives was also protective against ovarian cancer; adjusted OR 0.56 (95% CI, 0.40 to 0.78). No association was found for hormone replacement therapy, menopausal status, hysterectomy and family history of ovarian and/or breast cancer. Conclusion High parity and oral contraceptive use are associated with a lower risk of ovarian cancer in southern Chinese women.

Abstract
Second and higher-order malignancies now comprise about 18% of all incident cancers in the USA, superseding first primary cancers of the breast, lung, and prostate. The occurrence of second malignant neoplasms (SMN) is influenced by a myriad of factors, including the late effects of cancer therapy, shared aetiological factors with the primary cancer (such as tobacco use, excessive alcohol intake, and obesity), genetic predisposition, environmental determinants, host effects, and combinations of factors, including gene-environment interactions. The influence of these factors on SMN in survivors of adult-onset cancer is reviewed here. We also discuss how modifiable behavioural and lifestyle factors may contribute to SMN, and how these factors can be managed. Cancer survivorship provides an opportune time for oncologists and other health-care providers to counsel patients with regard to health promotion, not only to reduce SMN risk, but to minimize co-morbidities. In particular, the importance of smoking cessation, weight control, physical activity, and other factors consonant with adoption of a healthy lifestyle should be consistently emphasized to cancer survivors. Clinicians can also play a critical role by endorsing genetic counselling for selected patients and making referrals to dieticians, exercise trainers, and others to assist with lifestyle change interventions.

Abstract
PURPOSE The aim of this systematic review is to summarize the current knowledge about the etiology and pathogenesis of borderline tumors ovarian cancer with special emphasis on the role of endocrine treatments and reproductive factors to establish a foundation for future studies. METHODS We performed a systematic review on the relation between ovarian epithelial tumors (OET) and reproductive factors using the keywords: ovarian cancer, ovarian tumor, ovarian borderline tumor, age at menarche, age at menopause, parity, infertility, PCO syndrome, oral contraception, menopausal hormone therapy, fertility treatment. Totally, 3,290 abstracts were scanned for their relevance in this publication and 127 were finally included. RESULTS The incidence of ovarian epithelial cancer and ovarian borderline tumors is influenced by certain reproductive factors. The strongest protective effects are conferred by parity and use of oral contraceptive pills. Recent molecular biologic and histopathologic studies prove that OET represent a diverse group of tumors, each histologic type with a different genetic background. This is at least partly reflected in epidemiologic and clinical studies showing different risk modulating effects of reproductive factors and endocrine therapies on OET. CONCLUSIONS The etiology and pathogenesis of ovarian cancer are still not fully understood. None of the so far proposed hypothesis on the development of OET can fully account for the epidemiologic and clinical findings in the context of reproductive factors and OET development. Further research approaches are warranted and need to put more weight on the clinical and genetical diversity of OET to yield a more detailed insight into their pathogenesis.

Abstract
As more women survive reproductive cancers, menopausal symptoms following treatment can be a significant problem affecting quality of life and wellbeing. Hormone replacement therapy may or may not be contraindicated. Women often receive conflicting information about their management from different specialists. The aim of this study, based in a regional menopause clinic, was to examine referral patterns and symptom profiles of women with cancer or at high risk of cancer; to identify areas of need where a more integrated approach to management might be required; and to reach a local consensus across disciplines involved in the care of these women regarding prescribing of hormonal therapies. A retrospective case record review of all women attending Edinburgh Menopause Clinic for one 12-month period in 2011/2012 for management of cancer-related menopausal symptoms was undertaken. The results of the review were discussed at a multidisciplinary meeting and regional guidance on the management of these women was agreed.

Abstract
Although oral contraceptives have been available to women since the 1960s, contraceptive options for men have remained limited. Spermatogenesis relies on the active metabolite of vitamin A, retinoic acid, to drive spermatogonial differentiation and to allow the production of normal numbers of sperm. Recent evidence describes how the enzymes which control vitamin A metabolism in the testis could be targeted to generate effective male contraceptives; however, the detailed mechanism(s) regarding how vitamin A regulates normal spermatogenesis are still unknown. The essential nature of vitamin A to male germ cell development and the prospects of developing the proteins responsible for the generation, transport, and storage of retinoic acid as targets for male contraceptive development are discussed in this review.

Abstract
BACKGROUND Endometrial cancer (EC) predominantly occurs after menopause and is strongly related to steroid hormones, particularly estrogens. However, the relationship between these hormones and clinical characteristics remains unaddressed. EXPERIMENTAL DESIGN We analyzed the circulating levels of 18 steroids including adrenal precursors, androgens, estrogens, and their glucuronide metabolites, using specific and validated methods based on tandem mass spectrometry. Our goals were to compare circulating levels in postmenopausal women with EC (n = 126) with those of healthy postmenopausal women (n = 110) and to investigate how these hormonal levels relate to clinical characteristics. RESULTS After adjustment for potential confounders, most hormones were significantly elevated in EC patients compared with healthy controls. In women with type I cancer, estrogen levels were up to 3-fold those of healthy women (P < 0.05). These higher levels were associated with an increased risk of cancer, particularly estrogens and their direct precursors, testosterone and androstenedione (odds ratios ranging from 4.4 to 13.3; P ≤ 0.0003). Elevated circulating levels of estrogens and their metabolites were found in cancer cases with type I endometrioid cancer and low-grade and noninvasive tumor, suggesting an association between these hormones and the tumoral estrogenic activity. In addition, levels of estrone-sulfate in EC patients with relapse were 2-fold over levels of EC patients without relapse (P < 0.05), and 4.5-fold over those of healthy women (P < 0.001). CONCLUSIONS Circulating levels of steroids were associated with increased risk of EC. Estrogens may represent novel biomarkers predictive of clinical characteristics, including evidence for an increased risk of relapse.
