Reproductive Planning: Short-Acting Reversible Contraceptives.

Short-acting reversible contraceptives (SARCs) are prescribed routinely by primary care clinicians. SARCs are among the most commonly prescribed contraceptive methods and include combined hormonal oral contraceptive pills, the combined hormonal transdermal patch, the combined hormonal vaginal ring, progestin-only pills, and the 3-month depot medroxyprogesterone acetate injection. To ensure safe prescribing and reduce barriers to receiving SARC methods, family physicians should be familiar with two evidence-based national contraceptive guidelines, the U.S. Medical Eligibility Criteria for Contraceptive Use (U.S. MEC) and the U.S. Selected Practice Recommendations for Contraceptive Use (U.S. SPR). SARCs have benefits in addition to pregnancy prevention; as such, these methods may be chosen for reasons other than contraception.

Comparison of resumption of ovulation after cessation of oral contraceptives and medroxyprogesterone acetate in women with polycystic ovary syndrome.

OBJECTIVE: Both oral contraceptive pills (OCPs) and cyclic medroxyprogesterone acetate (MPA) are widely used to control menstrual abnormalities in women with polycystic ovary syndrome (PCOS). We aimed to evaluate the chance of ovulation resumption after cessation of OCPs and MPA in women with PCOS. METHODS: A retrospective study was conducted of women with PCOS who were treated with OCPs or cyclic MPA from September 2015 to March 2019. After cessation of medication, ovulation was assessed using basal body temperature and/or measurement of serum progesterone. The odds ratio for ovulation resumption was assessed with multivariable logistic regression. Additionally, doubly robust analysis was performed with inverse-probability-weighted analysis and regression adjustment based on the covariate balancing propensity score to adjust for the effect of covariates on the treatment assignment. RESULTS: Among 272 women with PCOS, 136 were prescribed OCPs and 136 were prescribed cyclic MPA. Ovulation resumed in 18.4% of women (n = 25) after cessation of MPA and in 24.3% of women (n = 33) after cessation of OCPs. The odds of ovulation resumption in MPA users were comparable with those in OCP users (adjusted odds ratio (aOR) 1.00, 95% confidence interval (CI) 0.89-1.12). After multiple imputation due to missing values, the results did not change substantially (aOR 0.99, 95% CI 0.89-1.10). CONCLUSIONS: Among women with PCOS, MPA users have a similar chance of ovulation resumption as OCP users after cessation of medication. Cyclic MPA can be a good alternative to OCPs in women for whom OCPs are contraindicated or who decline to take OCPs.

Oncologic, fertility, and obstetric outcomes with MPA therapy in women with endometrial cancer and atypical endometrial hyperplasia.

AIM: Medroxyprogesterone acetate (MPA) is one of the treatments of atypical endometrial hyperplasia (AEH) and endometrial cancer (EC) to preserve the fertility. Efficacy of MPA therapy and fertility and obstetric outcomes after remission were evaluated in EC or AEH patients. METHODS: Among patients diagnosed with EC or AEH at Tokushima University Hospital between January 2002 and October 2020, we retrospectively analyzed patients, ages range from 26 to 40, who underwent conservative management using MPA (400-600 mg/day). RESULTS: In total, 19 patients underwent MPA therapy. The 18 (94%) patients achieved complete response (CR), and 1 (5%) patient achieved partial response (PR). Relapse occurred in 6 (32%) patients who had achieved CR. Of the patients who relapsed, 4 patients resumed MPA therapy and were in remission. Among 19 patients, 13 patients attempted pregnancy after CR. All of them underwent ovulation induction or assisted reproductive technology. As a result, 20 pregnancies in 10 (77%) patients and 12 live births in 9 (69%) patients were achieved. Rate of spontaneous abortion was 35% (7/20). CONCLUSIONS: MPA therapy can produce a high remission rate, and be considered an effective treatment for patients who wish fertility preservation. Around 70% patients who attempt to pregnancy can have at least one baby by infertility treatments. Because recurrence rate after MPA therapy is high, it may be desirable to aim for early pregnancy by active intervention.

Vaginal microbiome, antiretroviral concentrations, and HIV genital shedding in the setting of hormonal contraception initiation in Malawi.

OBJECTIVE: The aim of this study was to understand how vaginal microbiota composition affects antiretroviral concentrations in the setting of hormonal contraception initiation. METHODS: Cervicovaginal fluid (CVF) concentrations of tenofovir, lamivudine, and efavirenz from 73 Malawian women with HIV were compared before and after initiation of depot-medroxyprogesterone acetate (DMPA) or levonorgestrel implant. We evaluated antiretroviral concentrations and vaginal microbiota composition/structure in the context of contraception initiation and predicted genital shedding using multivariable repeated measurements models fit by generalized estimating equations. RESULTS: Mean lamivudine CVF concentrations decreased 37% 1 month after contraception initiation. Subgroup analyses revealed a 41% decrease in women 1 month after initiating levonorgestrel implant, but no significant difference was observed in DMPA group alone. Tenofovir, lamivudine, and efavirenz CVF concentrations were positively correlated with anaerobic bacteria associated with nonoptimal vaginal microbiota. Risk of genital HIV shedding was not significantly associated with tenofovir or lamivudine CVF concentrations [tenofovir relative risk (RR): 0.098, P = 0.75; lamivudine RR: 0.142, P = 0.54]. Lack of association between genital HIV shedding and efavirenz CVF concentrations did not change when adjusting for vaginal microbiota composition and lamivudine/tenofovir CVF concentrations (RR: 1.33, P = 0.531). CONCLUSION: No effect of hormone initiation on genital shedding provides confidence that women with HIV on either DMPA or levonorgestrel implant contraception will not have compromised ART efficacy. The unexpected positive correlation between antiretroviral CVF concentrations and certain bacterial taxa relative abundance requires further work to understand the mechanism and clinical relevance.

Medroxyprogesterone as the Initial Systemic Treatment of Recurrent Endometrial Cancer: A Single Institutional Study.

BACKGROUND/AIM: Hormonal treatment is the preferred initial systemic therapy for patients with advanced or recurrent G1 or G2 endometrial cancer (EC) in terms of efficacy, toxicity, and economy. Few reports are available on the topic and we, therefore, conducted a retrospective study. PATIENTS AND METHODS: Patients with EC who received high-dose medroxyprogesterone (MPA) at our Hospital between January 2010 and December 2022 were reviewed. Patients who were treated for fertility preservation or had a history of systemic chemotherapy other than adjuvant therapy were excluded. RESULTS: Sixteen patients who were eligible for study inclusion had recurrent G1 or G2 EC. Their median age was 65 years (range=51-82 years), median body mass index was 22.6 kg/m2 (range=15.3-43.2 kg/m2), and all patients had an ECOG Performance Status of 0. All patients received 200 mg/day of MPA, and eight patients concomitantly received 100 mg/day of aspirin. None of the patients experienced severe adverse events. One patient had grade 2 deep vein thrombosis. Two patients discontinued MPA treatment because of adverse events. The response rate was 44% [95% confidence interval (CI)=20-68%] and median progression-free survival (PFS) was 6.9 months (95% CI=7.5-26 months). Four of 16 patients had PFS longer than 12 months, all of whom had positive tissue estrogen receptor (ER) and progesterone receptor (PR), and PFS at 2 years was 35% (95% CI=10.2-59.8%). CONCLUSION: Hormone therapy is effective long-term in ER- and PR-positive EC and can be recommended as initial systemic therapy. Toxicity is mild and manageable.

Curative Polyendocrine Therapy in a 21-year-Old Patient with Endometrial Carcinoma: Case Report and Review of the Literature.

INTRODUCTION: As the numbers of young patients diagnosed with early-stage endometrial carcinoma continue to rise, the question regarding fertility-preserving therapeutic options will increasingly gain significance in the future. CASE PRESENTATION: Here, we present the case of a 21-year-old patient diagnosed with symptomatic atypical endometrial hyperplasia. After 4 months of treatment with medroxyprogesterone acetate, a follow-up dilatation and curettage revealed early-stage, well-differentiated endometrioid endometrial carcinoma. Despite national guidelines recommending hysterectomy, the nulliparous patient expressed a desire to preserve her fertility. Subsequently, she underwent polyendocrine therapy with letrozole, everolimus, metformin, and Zoladex. Forty-three months after diagnosis, the patient successfully gave birth to a healthy child, and there have been no indications of recurrence thus far. DISCUSSION: This case suggests that triple endocrine therapy may be an option for selected patients with early endometrial cancer and a desire for fertility-sparing therapy.

Prognosis of patients with endometrial cancer or atypical endometrial hyperplasia after complete remission with fertility-sparing therapy.

PURPOSE: Although many patients with endometrial cancer (EC) or atypical endometrial hyperplasia (AEH) achieve complete remission (CR) after high-dose medroxyprogesterone acetate (MPA) treatment, no consensus has been reached on management after CR. Currently, patients receive estrogen-progestin maintenance therapy, but no recommendations exist regarding the duration of maintenance therapy or whether hysterectomy should be considered. This study aimed to provide insights into the management of EC/AEH after achieving CR. METHODS: We retrospectively investigated the prognosis of 50 patients with EC or AEH who achieved CR after MPA therapy. We assessed the association between disease recurrence and clinicopathological features and the pre- and post-operative histological diagnoses of patients who underwent hysterectomy. RESULTS: The median follow-up duration was 34 months (range: 1-179 months). Recurrence was observed in 17 patients. Among the clinical characteristics investigated, only the primary disease was significantly associated with disease recurrence; patients with EC had a higher risk of recurrence than those with AEH (p = 0.037). During the observation period, 27 patients attempted pregnancy, and 14 pregnancies resulted in delivery. Patients who gave birth had significantly longer relapse-free survivals than those who did not (p = 0.031). Further, 16 patients underwent hysterectomies, and AEH was detected postoperatively in 4 of 11 patients (36.4%) with no preoperative abnormalities. CONCLUSIONS: We identified several clinical features of patients with EC and AEH after CR. Given the high probability of endometrial abnormalities detected postoperatively, hysterectomy may be considered for patients who no longer want children.

MET Inhibits the Proliferation of EC Cells by Increasing MPA Sensitivity.

Context: The high resistance rate and high recurrence rate of progesterone only as a treatment for endometrial cancer (EC) limit its clinical application. Metformin (MET) may have antitumor ability. Combining MET and medroxyprogesterone acetate (MPA) may strengthen their inhibitory effects on proliferation of EC cells, but MET's mechanisms remain unclear. Objective: The study intended to identify the specific molecular mechanism that MET combined with MPA uses against EC progression. Design: The research team performed a controlled animal study. Setting: The study took place at Xuzhou Medical University in Xuzhou, China. Animals: The animals were16 female non-obese diabetic-severe combined immunodeficient (NOD-SCID) nude mice, about 12 to 16 g in weight. Interventions: The research team divided randomly, the mice into four groups and induced EC in all groups, four in each group: (1) The control group which received received normal saline, (2) the MPA group, which received 100 mg/kg of MPA; (3) the MET group, which received metformin at the rate of 200 mg/kg, each gavage volume was 0.1ml; (4) the MET+MPA group, which received 100 mg/kg of MPA and 200 mg/kg of MET. Outcome measures: The research team: (1) used a CCK-8 kit, an EdU assay, and a flow-cytometry assay to measure cancer-cell proliferation, count, and viability; determine the cell cycle; and measure apoptosis; (2) performed a Western blot analysis to determine the expression of the PR, CD133, pAkt, totalAkt, p-mTOR, and totalTOR antibodies; and (3) determined the size and volume of tumors in vivo and used immunohistochemical staining to determine expression of the Ki67 protein. Results: The MET+MPA group had a significantly lower number of cancer cells than the MET or MDA groups (both P < .001). That group also had significantly more stagnated cancer cells in the G0/G1 phase and significantly fewer cancer cells in the S phase or G2/M phase control, MET, or MPA groups (all P < .01). The MET+MPA group's PCNA and Ki-67 protein expression was significantly lower than that of the MET and MPA group. The EDU assay yielded similar results. Additionally, the MET+MPA group had significantly higher PR expression than that of to MET or MPA group (both P < .001). The MET and MPA groups' expression of CD133, p-Akt, and p-mTOR were significantly lower than those of the control group, while the MET+MPA group's levels were significantly lower than those of the MET and MPA groups. In-vivo experiments revealed that the MET and MPA groups did show decreased tumor size and volume. The MET+MPA group had tumor weights that were significantly lower and tumor volumes were significantly smaller than those of the MET and MPA groups (all P < .001). Immunohistochemical analysis revealed that the MET+MPA group's levels of the Ki-67 antigen were significantly lower than those of the MET and MPA groups. Conclusions: MET inhibited the proliferation of EC cells by increasing MPA-sensitivity, which was dependent on the inhibition of the CD133 expression and the Akt/mTOR pathway. In addition, if MET acts as an effective progestin sensitizer, it certainly offers promising therapeutic prospects for patients with early-stage EC or overgrown endometrium who have fertility requirements.

Is self-administered DMPA an answer to contraception access in the post-Roe era?

Compared with provider-administered depot medroxyprogesterone acetate, a prefilled formulation may offer patients improved access to effective contraception.

Comparison of the effectiveness of Dienogest with medroxyprogesterone acetate in the treatment of pelvic pain and recurrence of endometriosis after laparoscopic surgery.

PURPOSE: The aim of this study was to compare the effects of Dienogest and medroxyprogesterone acetate (MPA) on the recurrence of endometriosis lesions and clinical symptoms in women undergoing laparoscopic surgery. METHODS: This single center clinical trial was conducted among 106 women with endometriosis undergoing laparoscopic surgery who candidate receiving post-surgery hormone therapy. Participants were allocated to two groups. The first group received Dienogest pills (2 mg) daily for the first three months and then cyclic for three months afterward. The second group received MPA pills twice daily (10 mg) for three months and then cyclic for the next three months. Six months after the intervention, the rate of endometriosis recurrence, the size of endometriosis lesions and pelvic pain were assess and compared between two groups. RESULTS: Finally, data were evaluated based on 48 and 53 women in the Dienogest and MPA groups, respectively. After 6 months follow-up assessments the pelvic pain score was significantly lower in Dienogest group than MPA group (P < 0.001). There was not statistically difference between two groups in terms of recurrence rate of endometriosis (P = 0.4). Although the size of endometriosis cyst recurrence was smaller in Dienogest group compared to MPA group (P = 0.02). CONCLUSIONS: The findings showed that Dienogest treatment has better effect in reducing pelvic pain and the mean size of the recurrent endometriosis lesions after endometriosis laparoscopic surgery when compared to MPA treatment. Although the recurrent rate of endometriosis was similar between these treatments.

Management of Menopausal Symptoms: A Review.

Importance: Menopause, due to loss of ovarian follicular activity without another pathological or physiological cause, typically occurs between the ages of 45 years and 56 years. During the menopausal transition, approximately 50% to 75% of women have hot flashes, night sweats, or both (vasomotor symptoms) and more than 50% have genitourinary symptoms (genitourinary syndrome of menopause [GSM]). Observations: Vasomotor symptoms typically last more than 7 years and GSM is often chronic. Efficacious treatments for women with bothersome vasomotor symptoms or GSM symptoms include hormonal and nonhormonal options. Systemic estrogen alone or combined with a progestogen reduces the frequency of vasomotor symptoms by approximately 75%. Oral and transdermal estrogen have similar efficacy. Conjugated equine estrogens (CEE) with or without medroxyprogesterone acetate (MPA) were the only hormonal treatments for which clinical trials were designed to examine cardiovascular events, venous thromboembolism, and breast cancer risk. Compared with placebo, the increased risk of stroke and venous thromboembolism associated with CEE (with or without MPA) and breast cancer (with use of CEE plus MPA) is approximately 1 excess event/1000 person-years. Low-dose CEE plus bazedoxifene is not associated with increased risk of breast cancer (0.25%/year vs 0.23%/year with placebo). Bioidentical estrogens approved by the US Food and Drug Administration (with identical chemical structure to naturally produced estrogens, and often administered transdermally) also are available to treat vasomotor symptoms. For women who are not candidates for hormonal treatments, nonhormonal approaches such as citalopram, desvenlafaxine, escitalopram, gabapentin, paroxetine, and venlafaxine are available and are associated with a reduction in frequency of vasomotor symptoms by approximately 40% to 65%. Low-dose vaginal estrogen is associated with subjective improvement in GSM symptom severity by approximately 60% to 80%, with improvement in severity by 40% to 80% for vaginal prasterone, and with improvement in severity by 30% to 50% for oral ospemifene. Conclusions and Relevance: During the menopausal transition, approximately 50% to 75% of women have vasomotor symptoms and GSM symptoms. Hormonal therapy with estrogen is the first-line therapy for bothersome vasomotor symptoms and GSM symptoms, but nonhormonal medications (such as paroxetine and venlafaxine) also can be effective. Hormone therapy is not indicated for the prevention of cardiovascular disease.

Effects of Estradiol/Micronized Progesterone vs. Conjugated Equine Estrogens/Medroxyprogesterone Acetate on Breast Cancer Gene Expression in Healthy Postmenopausal Women.

Recent studies suggest estradiol (E2)/natural progesterone (P) confers less breast cancer risk compared with conjugated equine estrogens (CEE)/synthetic progestogens. We investigate if differences in the regulation of breast cancer-related gene expression could provide some explanation. This study is a subset of a monocentric, 2-way, open observer-blinded, phase 4 randomized controlled trial on healthy postmenopausal women with climacteric symptoms (ClinicalTrials.gov; EUCTR-2005/001016-51). Study medication was two 28-day cycles of sequential hormone treatment with oral 0.625 mg CEE and 5 mg of oral medroxyprogesterone acetate (MPA) or 1.5 mg E2 as percutaneous gel/day with the addition of 200 mg oral micronized P. MPA and P were added days 15-28/cycle. Material from two core-needle breast biopsies in 15 women in each group was subject to quantitative PCR (Q-PCR). The primary endpoint was a change in breast carcinoma development gene expression. In the first eight consecutive women, RNA was extracted at baseline and after two months of treatment and subjected to microarray for 28856 genes and Ingenuity Pathways Analysis (IPA) to identify risk factor genes. Microarray analysis showed 3272 genes regulated with a fold-change of >±1.4. IPA showed 225 genes belonging to mammary-tumor development function: 198 for CEE/MPA vs. 34 for E2/P. Sixteen genes involved in mammary tumor inclination were subject to Q-PCR, inclining the CEE/MPA group towards an increased risk for breast carcinoma compared to the E2/P group at a very high significance level (p = 3.1 × 10-8, z-score 1.94). The combination of E2/P affected breast cancer-related genes much less than CEE/MPA.

Obstetric outcomes after medroxyprogesterone acetate treatment for early stage endometrial cancer or atypical endometrial hyperplasia: a single hospital-based study.

BACKGROUND: To investigate perinatal outcomes in pregnancy after high-dose medroxyprogesterone acetate (MPA) therapy for early stage endometrial cancer (EC) and atypical endometrial hyperplasia (AEH) and to determine whether pregnancy after MPA therapy is at a higher risk of placenta accreta. METHODS: Data of 51 pregnancies in 46 women who received MPA therapy for EC or AEH and delivered after 22 weeks of gestation at Keio University Hospital were reviewed. A retrospective matched case-control study was performed to determine the risk of placenta accreta in pregnancy after MPA therapy compared with singleton pregnancies without any history of maternal malignancy treatments. RESULTS: The incidence of placenta accreta was higher in the MPA group than in the control group (15.7 vs. 0%, p = 0.0058). However, no differences in other perinatal outcomes were observed between groups. While gestational weeks at delivery in the MPA group were later than those in the control group (p = 0.0058), no difference in the incidence of preterm delivery was recorded between groups. In the MPA therapy group, the number of patients who underwent ≥ 6 dilation and curettage (D&C) was higher in the placenta accreta group than in the non-placenta accreta group (50.0 vs. 14.0%, p = 0.018). Patients with ≥ 6 D&Cs demonstrated a 6.0-fold increased risk of placenta accreta (p = 0.043, 95% CI 1.05-34.1) than those receiving ≤ 3 D&Cs. CONCLUSION: Pregnancy after MPA therapy is associated with a high risk of placenta accreta. In cases in which the frequency of D&C is high, placenta accreta should be considered.

Influence of Hormonal Contraceptive Use and HIV on Cervicovaginal Cytokines and Microbiota in Malawi.

Important questions remain on how hormonal contraceptives alter the local immune environment and the microbiota in the female genital tract and how such effects may impact susceptibility to HIV infection. We leveraged samples from a previously conducted clinical trial of Malawian women with (n = 73) and without (n = 24) HIV infection randomized to depot medroxyprogesterone acetate (DMPA) or the levonogestrel implant in equal numbers within each group and determined the effects of these hormonal contraceptives (HCs) on the vaginal immune milieu and the composition of the vaginal microbiota. Longitudinal data for soluble immune mediators, measured by multiplex bead arrays and enzyme-linked immunosorbent assays (ELISAs), and vaginal microbiota, assessed by 16S rRNA gene amplicon, were collected prior to and over a period of 180 days post-HC initiation. DMPA and levonogestrel had only minimal effects on the vaginal immune milieu and microbiota. In women with HIV, with the caveat of a small sample size, there was an association between the median log10 change in the interleukin-12 (IL-12)/IL-10 ratio in vaginal fluid at day 180 post-HC compared to baseline when these women were classified as having a community state type (CST) IV vaginal microbiota and were randomized to DMPA. Long-lasting alterations in soluble immune markers or shifts in microbiota composition were not observed. Furthermore, women with HIV did not exhibit increased viral shedding in the genital tract after HC initiation. Consistent with the results of the ECHO (Evidence for Contraceptive Options and HIV Outcomes) trial, our data imply that the progestin-based HC DMPA and levonorgestrel are associated with minimal risk for women with HIV. (This study has been registered at ClinicalTrials.gov under registration no. NCT02103660). IMPORTANCE The results of the Evidence for Contraceptive Options and HIV Outcomes (ECHO) trial, the first large randomized controlled clinical trial comparing the HIV acquisition risk of women receiving DMPA, the levonorgestrel (LNG) implant, or the copper intrauterine device (IUD), did not reveal an increased risk of HIV acquisition for women on any of these three contraceptives. Our study results confirm that the two different progestin-based hormonal contraceptives DMPA and levonogestrel will not increase the risk for HIV infection. Furthermore, DMPA and levonogestrel have only minimal effects on the immune milieu and the microbiota in the vaginal tract, attesting to the safety of these hormonal contraceptives.

Breastfeeding Perceptions and Behavior Among Postpartum Women Initiating Different Hormonally Systemic Contraceptive Methods.

BACKGROUND: There continues to be controversy regarding the simultaneous encouragement of both breastfeeding and immediate postpartum contraception. RESEARCH AIM: To explore postpartum women's perspectives about breastfeeding and their breastfeeding behaviors, while using one of three different hormonally systemic contraceptive methods immediately postpartum over a 6 month period of time. METHODS: This was a retrospective, longitudinal, three group comparative, secondary analysis of a prospective cohort study (N = 471) of immediate postpartum contraception. Breastfeeding, for this study, was defined as providing any human milk to the infant. Participants who chose one of three different hormonally systemic forms of contraception immediately postpartum (a long-acting hormonal reversible contraceptive (n = 200), depot medroxyprogesterone acetate 150 mg (n = 98), or a non-hormonal method (n = 173)) were compared at hospital discharge, 6 weeks, 3 months, and 6 months postpartum. The primary outcome was any breastfeeding at 6 months. Secondary outcomes included any and exclusive breastfeeding, concerns about breastfeeding while using contraception, and reasons for breastfeeding discontinuation. RESULTS: There was no significant difference in the rate of any breastfeeding between the two hormonal and the non-hormonal contraceptive groups at 6 months postpartum (long-acting hormonal 20.1%, non-hormonal 21.7%, depot medroxyprogesterone acetate 13.9%, p = .77, 0.28, respectively). The number of participants who reported stopping breastfeeding due to decreased milk supply was not significantly different between any groups at all time points (total number who discontinued at 6 months postpartum was long-acting hormonal 24.7%, non-hormonal 25.1%, depot medroxyprogesterone acetate 19.3%, p = .30). CONCLUSIONS: Breastfeeding perspectives and behavioral outcomes over the first 6 months postpartum were not influenced by participants chosen form of immediate postpartum contraception.

Medroxyprogesterone Acetate versus Gonadotropin-Releasing Hormone Antagonist for the Prevention of Premature Luteinizing Hormone Surge in hyper-responder women undergoing controlled ovarian stimulation for IVF/ICSI Cycles.

OBJECTIVE: To compare the effect of Medroxyprogesterone acetate versus Gonadotropin releasing hormone antagonist for the prevention of premature luteinizing hormone (LH) surge in infertile hyper-responder women undergoing controlled ovarian stimulation for in vitro fertilization (IVF) /intracytoplasmic sperm injection (ICSI) cycles. METHODS: One hundred infertile hyper-responder women who were candidate for IVF/ICSI were randomly assigned into two groups. Group 1 was given 20 mg Medroxyprogesterone acetate from day 1 of the menstrual cycle till trigger day. Group 2 was given GnRH antagonist (injection Cetrorelix 0.25 mg s/c) from the day when the leading follicle reached 14 mm until the day of trigger for the prevention of premature LH surge (flexible protocol). We measured LH serum levels on day 1, day 7 of cycle and on trigger day. The primary outcome measured was the incidence of premature LH surge. Other outcome measures were total number of mature follicles on trigger day, total number of mature oocytes retrieved and number of good quality day-3 embryos. RESULTS: There was no premature luteinizing hormone surge in both groups of our study. The mean number of follicles on trigger day, mean number of M2 oocytes retrieved and mean number of good quality day-3 embryos were comparable in both the groups, with no statistically significant difference. CONCLUSIONS: The results of this study stated that MPA can be an effective alternative to GnRH antagonist for the prevention of premature LH surge in hyper-responder women undergoing COS for IVF. It is easy to use, widely available and cost-effective. It may establish a new regimen of ovarian stimulation using MPA as an oral alternative to GnRH antagonist treatment in hyper-responders.

Retrospective study on the effectiveness of medroxyprogesterone acetate in the treatment of ER-positive/HER2-negative post-menopausal advanced breast cancer: an additional analysis of the JBCRG-C06 Safari study.

BACKGROUND: Only old evidence exists to back up the use of medroxyprogesterone acetate. Therefore, this study aimed to explore the factors that influence the time to treatment failure of medroxyprogesterone acetate in real-world settings as late-line treatment. METHODS: This was a cohort study that used the database of the Safari study on oestrogen receptor-positive post-menopausal advanced breast cancer (UMIN000015168). We created Kaplan-Meier curves for time to treatment failure with medroxyprogesterone acetate. Further, univariate and multivariate analyses were performed using a Cox hazard model of the clinicopathological factors involved in the time to treatment failure of medroxyprogesterone acetate. RESULTS: From the 1031 patients in the Safari study, 279 patients were selected as the population for the analysis of effectiveness of medroxyprogesterone acetate monotherapy. In the analysis of medroxyprogesterone acetate by treatment line, the median time to treatment failure was 3.0 months for third-line treatment and 4.1 months for fourth and subsequent treatment lines. In cases where medroxyprogesterone acetate was used as a third-line or later endocrine treatment, multivariate analysis showed that the length of the disease-free interval was correlated with the length of time to treatment failure of medroxyprogesterone acetate (P = 0.004). With medroxyprogesterone acetate monotherapy as the fourth-line or later treatment, 20% of the patients achieved a time to treatment failure of 12 months or longer. CONCLUSION: In actual clinical practice, patients treated with medroxyprogesterone acetate alone as the fourth or subsequent treatment lines showed a time to treatment failure of 4 months, suggesting that there is merit in using medroxyprogesterone acetate even in late treatment lines, especially in patients with long disease-free interval and those who are difficult to treat using other antineoplastic agents.

Evaluation of the Safety and Efficacy of Ormeloxifene, a Selective Estrogen Receptor Modulator and Medroxyprogesterone Acetate in Women with Non-Structural Abnormal Uterine Bleeding: A Randomized Clinical Trial.

Background and objectives: Abnormal uterine bleeding is a significant clinical and gynaecological concern that necessitates its safe and effective treatment. The present study aims to compare the cost-effectiveness, safety, efficacy, and health-related quality of life of ormeloxifene with medroxyprogesterone acetate in women with non-structural abnormal uterine bleeding. Materials and Methods: A prospective, randomized, single-blinded clinical trial of 367 patients was carried out at a tertiary care hospital for a period of one year from 5 January 2019 to 4 January 2020. Patients were randomized into two groups for administering ormeloxifene and medroxyprogesterone acetate for a 3-month treatment duration and were evaluated by laboratorial investigations like anaemic status, bleeding duration, endometrial thickness, pictorial blood loss assessment chart (PBLAC) score, and patient's medical and medication history. Health-related quality of life was assessed using short form survey-36 (SF-36) questionnaire scale. Cost-effectiveness was determined on the basis of the three-month treatment regimen. Results: The mean duration of bleeding reduced from 16.88 ± 6.46 to 7.76 ± 1.55 in the ormeloxifene group and from 15.91 ± 5.04 to 8.7 ± 1.91 (p < 0.001) in the medroxyprogesterone acetate. Similarly, mean haemoglobin increased from 8.56 ± 0.77 to 10.1 ± 0.087 g/dL and from 8.60 ±0.97 to 9.551 ± 0.90 g/dL (p < 0.001), and endometrial thickness showed a reduction from 8.52 ± 1.61 mm to 6.92 ± 1.68 mm and from 8.40 ± 2.09 mm to 7.85 ± 2.0 mm (p < 0.001) in the ormeloxifene and medroxyprogesterone acetate groups, respectively. PBLAC score reduced from 289.92 ± 42.39 to 128.11 ± 33.10 and from 287.38 ± 40.94 to 123.5 ± 29.57 (p < 0.001) in these groups, respectively. Health-related quality of life improved in the ormeloxifene group more than the medroxyprogesterone group, which was evidenced by SF-36 scale parameters (physical function, energy/fatigue and pain) that changed from 24.39, 12.99, 6.25 to 28.95, 18, 9 and from 25.41, 13.6, 7.1 to 27.02, 16, 8.3 in the ormeloxifene and medroxyprogesterone acetate groups, respectively. Conclusions: The study concludes that both medroxyprogesterone acetate and ormeloxifene are safe and efficacious in controlling abnormal uterine bleeding, but ormeloxifene was the better of the two in terms of cost effectiveness, reduction in pictorial blood loss assessment score, endometrial thickness, bleeding duration (days), increase in haemoglobin concentration (g/dL) and improvement in the quality of life.

Fertility-Sparing Approach in Patients with Endometrioid Endometrial Cancer Grade 2 Stage IA (FIGO): A Qualitative Systematic Review.

Background: Endometrial cancer (EC) is one of the most common gynecologic malignancy, mostly in postmenopausal women. The gold standard treatment for EC is surgery, but in the early stages, it is possible to opt for conservative treatment. In the last decade, different clinical and pathological markers have been studied to identify women who respond to conservative treatment. A lot of immunohistochemical markers have been evaluated to predict response to progestin treatment, even if their usefulness is still unclear; the prognosis of this neoplasm depends on tumor stage, and a specific therapeutic protocol is set according to the stage of the disease. Objective: (1) To provide an overview of the conservative management of Stage 1A Grade (G) 2 endometrioid EC (FIGO) and the oncological and reproductive outcomes related; (2) to describe the molecular alterations before and after progestin therapy in patients undergoing conservative treatment. Materials and Methods: A systematic computerized search of the literature was performed in the main electronic databases (MEDLINE, Embase, Web of Science, PubMed, and Cochrane Library), from 2010 to September 2021, in order to evaluate the oncological and reproductive outcomes in patients with G2 stage IA EC who ask for fertility-sparing treatment. The expression of several immunohistochemical markers was evaluated in pretreatment phase and during the follow-up in relation to response to hormonal therapy. Only scientific publications in English were included. The risk of bias assessment was performed. Review authors' judgments were categorized as "low risk," "high risk," or "unclear risk" of bias. Results: Twelve articles were included in the study: 7 observational studies and 5 case series/reports. Eighty-four patients who took progestins (megestrol acetate, medroxyprogesterone acetate, and/or levonorgestrel-releasing intrauterine devices) were analyzed. The publication bias analysis turned out to be "low." 54/84 patients had a complete response, 23/84 patients underwent radical surgery, and 20/84 had a relapse after conservative treatment. Twenty-two patients had a pregnancy. The length of follow-up was variable, from 6 to 142 months according to the different studies analyzed. Several clinical and pathological markers have been studied to identify women who do not respond to conservative treatment: PR and ER were the most studied predictive markers, in particular PR appeared as the most promising; MMR, SPAG9, Ki67, and Nrf2-survivin pathway provided good results with a significant association with a good response to progestin therapy. However, no reliable predictive markers are currently available to be used in clinical practice. Conclusions: The conservative treatment may be an option for patients with stage IA G2 EEC who desire to preserve their fertility. The immunohistochemical markers evaluation looks promising in predicting response to conservative treatment. Further large series and randomized clinical trials are needed to confirm these results.

Identification of Candidate Genes in Breast Cancer Induced by Estrogen Plus Progestogens Using Bioinformatic Analysis.

Menopausal hormone therapy (MHT) was widely used to treat menopause-related symptoms in menopausal women. However, MHT therapies were controversial with the increased risk of breast cancer because of different estrogen and progestogen combinations, and the molecular basis behind this phenomenon is currently not understood. To address this issue, we identified differentially expressed genes (DEGs) between the estrogen plus progestogens treatment (EPT) and estrogen treatment (ET) using the Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) data. As a result, a total of 96 upregulated DEGs were first identified. Seven DEGs related to the cell cycle (CCNE2, CDCA5, RAD51, TCF19, KNTC1, MCM10, and NEIL3) were validated by RT-qPCR. Specifically, these seven DEGs were increased in EPT compared to ET (p < 0.05) and had higher expression levels in breast cancer than adjacent normal tissues (p < 0.05). Next, we found that estrogen receptor (ER)-positive breast cancer patients with a higher CNNE2 expression have a shorter overall survival time (p < 0.05), while this effect was not observed in the other six DEGs (p > 0.05). Interestingly, the molecular docking results showed that CCNE2 might bind to 17ß-estradiol (−6.791 kcal/mol), progesterone (−6.847 kcal/mol), and medroxyprogesterone acetate (−6.314 kcal/mol) with a relatively strong binding affinity, respectively. Importantly, CNNE2 protein level could be upregulated with EPT and attenuated by estrogen receptor antagonist, acolbifene and had interactions with cancer driver genes (AKT1 and KRAS) and high mutation frequency gene (TP53 and PTEN) in breast cancer patients. In conclusion, the current study showed that CCNE2, CDCA5, RAD51, TCF19, KNTC1, MCM10, and NEIL3 might contribute to EPT-related tumorigenesis in breast cancer, with CCNE2 might be a sensitive risk indicator of breast cancer risk in women using MHT.
