Impact of Gender-Affirming Hormonal Therapy on Cardiovascular Risk Factors in Transgender Health: An Updated Meta-Analysis.

Background: Gender-affirming hormone therapy (GAHT) is common among transgender individuals, but its impact on lipid profile and cardiovascular health is not well studied. Objectives: The authors performed a systematic review and meta-analysis of existing literature to assess the impact of GAHT on lipid profiles and metabolic cardiovascular risk factors in transgender individuals. Methods: Online databases including MEDLINE/PubMed, Embase, and Cochrane Central registry were searched to find studies on lipid profile changes in women who are transgender, also referred to as transfeminine (TF), and men who are transgender, also referred to as transmasculine (TM) before and after GAHT. Baseline comorbidities were analyzed using descriptive statistics, and R-statistical software was used to analyze the mean difference in lipid profile change between the two cohorts (pre- and post-GAHT therapy) including transgender patients. Results: Overall, 1,241 TM and 992 TF patients were included from 12 observational studies and 12 randomized controlled trials. The mean age among TM and TF was 28 years and 30 years, respectively. The mean follow-up duration (including pre- and post-GAHT therapy) was 28 months in TM patients and 39 months in TF patients. When compared to baseline measures, TM patients had a significant increase in low-density lipoprotein, triglyceride levels, and total cholesterol while high-density lipoprotein levels decreased. In TF patients, there was a significant increase in triglyceride levels. Conclusions: GAHT affects lipid profiles in transgender patients; however, additional studies are needed to determine how these changes impact clinical outcomes.

Real-World Effectiveness of Menopausal Hormone Therapy in Preventing Relapse in Women With Schizophrenia or Schizoaffective Disorder.

OBJECTIVE: Antipsychotic effectiveness in preventing relapse declines around menopausal age in women with schizophrenia or schizoaffective disorder (SSD). It is not known whether systemic menopausal hormone therapy (MHT) can help to prevent psychosis relapse. METHODS: A within-subject study design was used to study the effectiveness of MHT in preventing relapse in a Finnish nationwide cohort of women with SSD between 40 and 62 years of age who used MHT during follow-up (1994-2017). Hazard ratios adjusted for age and psychotropic drug use were calculated for psychosis relapse as main outcome and any psychiatric hospitalization as secondary outcome. RESULTS: The study population comprised 3,488 women using MHT. Use of MHT was associated with a 16% lower relapse risk (adjusted hazard ratio [aHR]=0.84, 95% CI=0.78-0.90) when compared to non-use. Stratified by age, MHT was associated with decreased relapse risks when used between ages 40-49 (aHR=0.86, 95% CI=0.78-0.95) and ages 50-55 (aHR=0.74, 95% CI=0.66-0.83), but not between ages 56-62 (aHR=1.11, 95% CI=0.91-1.37). Similar effectiveness was found for estrogen alone or combined with fixed or sequential progestogens (aHRs between 0.79 and 0.86), transdermal and oral formulations (aHRs 0.75-0.87), and for most specific formulations (aHRs 0.75-0.85), except tibolone (aHR=1.04, 95% CI=0.75-1.44) and formulations with dydrogesterone (aHR=1.05, 95% CI=0.85-1.30). Similar results were observed with any psychiatric hospitalization as outcome measure. CONCLUSIONS: The findings underscore the potential value of MHT in preventing psychosis relapse among women with SSD of menopausal age. These findings translate clinical evidence on the neuroprotective effects of estrogens to real-world settings, encompassing a group of women for whom current antipsychotic treatment options may be insufficient.

Early and repetitive novel-tracer PET-guided stereotactic body radiotherapy for nodal oligorecurrent prostate cancer after definitive first-line therapy.

BACKGROUND: Prostate-specific membrane antigen (PSMA) positron-emission tomography (PET) imaging can detect prostate cancer (PCa) nodal oligorecurrences (NOR) at very low prostate-specific antigen (PSA) levels. Prospective studies on oligorecurrent (OR) PCa have been hampered by either dated diagnostics or inhomogeneous cohorts and/or treatment approaches. We hypothesized that early and-if necessary and feasible-repetitive PSMA-PET-based metastasis-directed therapy (MDT) using stereotactic body radiotherapy (SBRT) would improve freedom from palliative (systemic) therapy at low toxicity. METHODS: This study is a retrospective analysis of patients treated for OR PCa after definitive first-line therapy using PSMA-PET/CT-based SBRT. Endpoints were biochemical progression-free survival (bPFS), SBRT-free survival (SBRT-FS), androgen deprivation therapy (ADT)-free survival (ADT-FS), and toxicity. RESULTS: A total of 67 patients and 248 metastases (211 nodal) were treated. Patients on concurrent ADT were excluded. Median PSA at inclusion was 2.175 ng/ml. bPFS, SBRT-FS, and ADT-FS for multiple-course SBRT were 9.5, 19.5, and 35.0 months, respectively; 32 patients had ≥ 1 course of SBRT. Median PSA nadir was 0.585 ng/ml. There was no ≥ grade 2 toxicity. CONCLUSION: Modern-tracer PET/CT-based early and repetitive focal SBRT yields promising results with regard to bPFS, SBRT-FS, and ADT-FS with low toxicity. The ability of this approach to postpone initiation of palliative treatment with low toxicity should be re-evaluated prospectively.

Gender-affirming hormonal therapy induces a gender-concordant fecal metagenome transition in transgender individuals.

BACKGROUND: Limited data exists regarding gender-specific microbial alterations during gender-affirming hormonal therapy (GAHT) in transgender individuals. This study aimed to investigate the nuanced impact of sex steroids on gut microbiota taxonomy and function, addressing this gap. We prospectively analyzed gut metagenome changes associated with 12 weeks of GAHT in trans women and trans men, examining both taxonomic and functional shifts. METHODS: Thirty-six transgender individuals (17 trans women, 19 trans men) provided pre- and post-GAHT stool samples. Shotgun metagenomic sequencing was used to assess the changes in gut microbiota structure and potential function following GAHT. RESULTS: While alpha and beta diversity remained unchanged during transition, specific species, including Parabacteroides goldsteinii and Escherichia coli, exhibited significant abundance shifts aligned with affirmed gender. Overall functional metagenome analysis showed a statistically significant effect of gender and transition (R2 = 4.1%, P = 0.0115), emphasizing transitions aligned with affirmed gender, particularly in fatty acid-related metabolism. CONCLUSIONS: This study provides compelling evidence of distinct taxonomic and functional profiles in the gut microbiota between trans men and women. GAHT induces androgenization in trans men and feminization in trans women, potentially impacting physiological and health-related outcomes. TRIAL REGISTRATION: Clinicaltrials.gov NCT02185274.

Nuances of gender affirming therapy for transgender women with spinal cord injury.

CASE DESCRIPTION: 56-year-old transgender woman with new spinal cord injury (SCI) on gender affirming hormonal therapy (GAHT) with estrogen and spironolactone. FINDINGS: After her injury, estrogen and spironolactone were discontinued, for blood clots and hypotension, respectively. Alternative options were explored. CLINICAL RELEVANCE: Little is known about GAHT in SCI for transgender women. Shared decision making should be used to navigate risks, benefits, and alternative options.

Menopausal symptoms and utilization of menopausal hormone therapy among women aged 40-60 years in Addis Ababa, Ethiopia: a cross-sectional study.

BACKGROUND: The onset of menopause leads to diminished estrogen exposure, resulting in a high morbidity burden related to menopausal symptoms. Menopausal hormonal therapy is an effective therapy that offers more advantages than disadvantages for women aged less than 60 years or who have had menopause for less than 10 years. OBJECTIVE: This study aimed to assess the prevalence of menopausal symptoms, identify factors associated with menopausal symptoms, and assess the use of menopausal hormone therapy among women aged 40-60 who visited the gynecological clinics of three hospitals in Addis Ababa, Ethiopia. METHODS: A facility-based cross-sectional study was conducted from January 2022 to June 2022 at Gandhi Memorial Hospital, Tikur Anbessa Hospital, and Zewditu Memorial Hospital on 296 middle-aged women. Data were collected using an interviewer-administered structured questionnaire and analyzed for sociodemographic factors, utilization of menopausal hormone therapy, and prevalence of menopausal symptoms using the menopause rating scale. Data were analyzed using SPSS version 25. Bivariate and multivariate logistic regression analyses were performed to identify independent predictors of each subscale of menopausal symptoms. The strength of the association was measured using odds ratios with 95% confidence intervals, and statistical significance was set at a value of P < 0.05. RESULT: The prevalence of menopausal symptoms was 89.9%. According to the menopausal rating scale, the frequency of reported symptoms was hot flushes (54.7%), muscle and joint pain (32.1%) on the somatic subscale; physical and mental exhaustion (55.1%), irritability (48.6%) on psychological subscale; and sexual problems (41.3%), bladder problems (39.2%) on urogenital subscale. This study also showed that the age of women [aOR: 0.317, 95%CI (0.102, 0.990)], and monthly family income [aOR = 0.182, 95% CI (0.041, 0.912)] were significantly associated with somatic menopausal symptoms. There was no utilization of menopausal hormonal therapy to treat menopausal symptoms and to prevent complications. CONCLUSION: The prevalence of menopausal symptoms is high; however, the utilization of individualized administration of menopausal hormone therapy according to symptoms is negligible. It appears essential for these institutions to work on service availability and delivery of menopausal hormone therapy for those in need of wider benefits for their clients.

Predictors of Progression to Castration-resistant Prostate Cancer After Radical Prostatectomy in High-risk Prostate Cancer Patients.

Background/Aim: To examine the specific time frame and identify associated risk factors from commencement of hormonal therapy to the onset of castration-resistant prostate cancer among patients who have developed biochemical recurrence following radical prostatectomy. Patients and Methods: We retrospectively reviewed the records of 92 patients who developed biochemical recurrence and received hormonal therapy as initial salvage treatment after radical prostatectomy for high-risk localized prostate cancer from 2005 to 2021. The castration-resistant prostate cancer-free survival rates from the commencement of salvage hormonal therapy were analyzed using log-rank methods. Cox proportional hazard regression was performed to analyze the risk factors associated with acquiring castration resistance. The patients were stratified based on those risk factors. Results: During a median follow-up duration of 57 months, 24 (26.1%) patients developed castration-resistant prostate cancer. The 5- and 10-year castration-resistant prostate cancer-free survival rates were 73.6% and 54.5%, respectively. A multivariate analysis showed that Grade Group of 5 and prostate-specific antigen doubling time at biochemical recurrence of ≤3 months were independent predictors of castration-resistant prostate cancer. The 5-year castration-resistant prostate cancer-free survival rates in the low- and high-risk groups, stratified according to the aforementioned factors, were 85.4% and 47.6%, respectively. Conclusion: Patients in high Grade Group and short prostate-specific antigen doubling time after radical prostatectomy are more likely to develop resistance to salvage hormonal therapy.

Impact of HDAC6-mediated progesterone receptor expression on the response of breast cancer cells to hormonal therapy.

Modulation of estrogen receptor (ER) and progesterone receptor (PR) expression, as well as their emerging functional crosstalk, remains a potential approach for enhancing the response to hormonal therapy in breast cancer. Aberrant epigenetic alterations induced by histone deacetylases (HDACs) were massively implicated in dysregulating the function of hormone receptors in breast cancer. Although much is known about the regulation of ER signaling by HDAC, the precise role of HDAC in modulating the expression of PR and its impact on the outcomes of hormonal therapy is poorly defined. Here, we demonstrate the involvement of HDAC6 in regulating PR expression in breast cancer cells. The correlation between HDAC6 and hormone receptors was investigated in patients' tissues by immunohistochemistry (n = 80) and publicly available data (n = 3260) from breast cancer patients. We explored the effect of modulating the expression of HDAC6 as well as its catalytic inhibition on the level of hormone receptors by a variety of molecular analyses, including Western blot, immunofluorescence, Real-time PCR, RNA-seq analysis and chromatin immunoprecipitation. Based on our in-silico and immunohistochemistry analyses, HDAC6 levels were negatively correlated with PR status in breast cancer tissues. The downregulation of HDAC6 enhanced the expression of PR-B in hormone receptor-positive and triple-negative breast cancer (TNBC) cells. The selective targeting of HDAC6 by tubacin resulted in the enrichment of the H3K9 acetylation mark at the PGR-B gene promoter region and enhanced the expression of PR-B. Additionally, transcriptomic analysis of tubacin-treated cells revealed enhanced activity of acetyltransferase and growth factor signaling pathways, along with the enrichment of transcription factors involved in the transcriptional activity of ER, underscoring the crucial role of HDAC6 in regulating hormone receptors. Notably, the addition of HDAC6 inhibitor potentiated the effects of anti-ER and anti-PR drugs mainly in TNBC cells. Together, these data highlight the role of HDAC6 in regulating PR expression and provide a promising therapeutic approach for boosting breast cancer sensitivity to hormonal therapy.

Effectiveness of combined targeted and hormonal therapies for post-menopausal women with hormone receptor-positive and HER2-negative advanced breast cancer: A systematic review and meta-analysis of RCTs.

OBJECTIVE: we aim to synthesize available evidence on the effectiveness of hormonal plus targeted therapies for post-menopausal women with hormone receptor-positive and HER2-negative advanced breast cancer. DATA SOURCES AND METHODS: We searched the following databases: Medline, PubMed, Cochrane Library, CINAHL, Web of Science, Scopus, and African Journal. Only studies that investigated the effectiveness of hormonal therapy combined with targeted therapy for HR+/HER2- advanced breast cancer treatment were included. The outcomes were progression-free survival (PFS), overall survival (OS) and objective response rate (ORR). A random-effect meta-analysis model was employed. Statistical analysis was performed using Comprehensive Meta-analysis version 3. RESULTS: 24 studies were included in the meta-analysis with an overall sample size of 7635. Median PFS, OS and ORR were found to be significantly increased in the combination group compared to hormonal monotherapy [SMD = 6.072 (95% CI = 3.785-8.360), p < 0.001], [SMD = 1.614 (95% CI = 0.139-3.089), p = 0.032] and [OR = 1.584 (CI 1.134-2.213), p = 0.007] respectively. Subgroup analysis showed a significant difference in PFS and ORR between patients who received "hormonal therapy + CDK4/6 inhibitors" vs hormonal therapy only [SMD = 6.015 (CI 3.069-8.960), p < 0.001], (OR = 1.828 (CI 1.030-3.243), p = 0.039] respectively. CONCLUSION: Compared with hormonal monotherapy, targeted plus hormonal therapy significantly improves PFS, OS and ORR in postmenopausal women with HR+/HER2- advanced breast cancer.

A randomized phase II trial on the addition of dutasteride to combined androgen blockade therapy versus combined androgen blockade therapy alone in patients with advanced or metastatic salivary duct carcinoma - the DUCT study protocol.

BACKGROUND: Salivary duct carcinoma (SDC) is a rare and aggressive subtype of salivary gland cancer, frequently associated with incurable recurrences and distant metastases (R/M). Proliferation of SDC relies on androgen receptor (AR) signalling, prompting the use of combined androgen blockade (CAB, i.e., luteinizing hormone-releasing hormone agonist and/or AR antagonists) to R/M SDC patients. However, only a subset of patients benefits from such treatments. We have shown that response to CAB is associated with steroid 5α-reductase 1 (SRD5A1) mRNA expression. SRD5A1 catalyses the intracellular conversion of testosterone into the more potent AR-agonist dihydrotestosterone. This conversion can be inhibited by dutasteride, a potent SRD5A1-inhibitor, which is currently prescribed for benign prostatic hyperplasia. We hypothesize that repurposing dutasteride to target AR signalling in SDC could enhance therapeutic response and clinical outcome in SDC patients. METHODS: This prospective, open-label, randomized controlled phase II clinical trial, is designed to investigate whether dutasteride as an adjunct drug to CAB improves response rate and clinical outcome in patients with AR-positive R/M SDC. Patients are divided in two cohorts based on their prior systemic treatments. In cohort A, CAB-naïve patients (n = 74) will be randomly assigned to either a control arm (Arm 1) receiving CAB (goserelin 10.8 mg/3m and bicalutamide 50 mg/OD) or an experimental arm (Arm 2) where dutasteride (0.5 mg/OD) is added to the CAB regimen. In cohort B, patients with disease progression after adjuvant or first-line palliative CAB therapy (max. n = 24) will receive goserelin, bicalutamide, and dutasteride to assess whether the addition of dutasteride can overcome therapy resistance. The primary endpoints are the objective response rate and duration of response. Secondary endpoints are progression-free survival, overall survival, clinical benefit rate, quality of life, and safety. Translational research will be performed to explore molecular target expression differences and their correlation with clinical outcome. DISCUSSION: The DUCT study addresses an unmet medical need by investigating the repurposing of dutasteride to enhance treatment response and improve clinical outcome for patients with R/M SDC, especially those with limited alternative treatment options, such as HER2-negative cases. By repurposing a registered low-cost drug, this trial's findings could be readily applied into clinical practice. TRIAL REGISTRATION: Clinicaltrials.gov Identifier: NCT05513365. Date of registration: August 24, 2022. PROTOCOL VERSION: Current protocol version 4.0, February 21, 2024.

Uterine preservation in low-grade endometrial stromal sarcoma.

Data on uterine preservation in the management of low grade endometrial stromal sarcoma (LGESS) is scarce due to rarity of this tumor type. Standard management of LGESS involves extrafascial hysterectomy with bilateral salpingo-oophorectomy with debulking of any extrauterine metastatic disease. High estrogen and progesterone receptor expression facilitates adjuvant hormone therapy post-surgery. LGESS frequently affects young women, thus fertility preservation is an important issue in management. Here we describe uterine preservation in two young women diagnosed with LGESS followed by GnRH analogue therapy with favorable outcome. The first case was diagnosed with recurrent endometrial polyp invading myometrium requiring wedge resection of uterus with free margins. Second case presented with a vaginal mass arising from cervix and excision was done through vaginal route. Both patients were prescribed GnRH analogue therapy for six months post-surgery and are currently on follow-up. These case reports add to literature on feasibility of uterine preservation in the management of LGESS.

How We Treat Metastatic Castration-Sensitive Prostate Cancer.

The treatment of metastatic castration-sensitive prostate cancer (mCSPC) has seen remarkable breakthroughs over the last few years. Diagnostic and therapeutic advances have given rise to debates about risk stratification and optimal first-line treatment selection, as well as to concerns about potential overtreatment in a disease state with a highly heterogeneous clinical behavior. Here, we use case reports from our practice to review the clinical trials exploring intensified triplet regimens combining androgen deprivation therapy with second-generation androgen receptor signaling inhibitors and docetaxel, and we offer our recommendations on how to best select candidates for these novel combinations. Furthermore, the growing adoption of PET imaging with increasingly sensitive and prostate tissue-specific tracers replacing conventional staging technologies has led to the identification of a subset of low-volume mCSPC with nodal metastases which would otherwise not be considered abnormal by RECIST criteria. We describe our PSA-adapted approach to treatment in this unique population with non-measurable low-volume mCSPC which has not been specifically investigated in any phase III clinical trials. We also discuss ongoing clinical trials evaluating treatment de-escalation strategies. Finally, we review how local treatment modalities directed at the prostate or distant sites of disease in oligometastatic CSPC may benefit patients, and how we incorporate metastasis-directed therapy in the management of mCSPC.

CDK4/6 and aromatase inhibitors as first-line treatment in metastatic high-grade neuroendocrine carcinoma of the breast: A case report.

Key Clinical Message: There is no consensus regarding the therapeutic approach of breast neuroendocrine carcinomas (NECs). As most NECs are hormone receptor positive and HER-2 negative, we suggest that endocrine-based strategies may play a leading role. Here, we report a new treatment strategy by incorporating CDK4/6 inhibitors in the therapeutic armamentarium. Abstract: Primary neuroendocrine neoplasms of the breast constitute a rare entity. They are characterized by predominant neuroendocrine differentiation and are further divided into well-differentiated neuroendocrine tumors and poorly differentiated (high-grade) neuroendocrine carcinomas (NECs). Regarding their therapeutic approach, there are no standardized guidelines. Herein, we present the first case ever reported, concerning a female patient with de novo metastatic breast NEC who received hormonal therapy, a combination of a CDK4/6 inhibitor palbociclib with letrozole and triptorelin, as first-line treatment with significant clinical and radiological response. As most NECs are estrogen receptor and/or progesterone receptor positive and HER-2 negative, we suggest that hormonal therapy may play a leading role even in the first-line setting. The present report provides a new treatment strategy by incorporating CDK4/6 inhibitors in the therapeutic armamentarium of breast NECs.

Optimizing word embeddings for small dataset: a case study on patient portal messages from breast cancer patients.

Patient portal messages often relate to specific clinical phenomena (e.g., patients undergoing treatment for breast cancer) and, as a result, have received increasing attention in biomedical research. These messages require natural language processing and, while word embedding models, such as word2vec, have the potential to extract meaningful signals from text, they are not readily applicable to patient portal messages. This is because embedding models typically require millions of training samples to sufficiently represent semantics, while the volume of patient portal messages associated with a particular clinical phenomenon is often relatively small. We introduce a novel adaptation of the word2vec model, PK-word2vec (where PK stands for prior knowledge), for small-scale messages. PK-word2vec incorporates the most similar terms for medical words (including problems, treatments, and tests) and non-medical words from two pre-trained embedding models as prior knowledge to improve the training process. We applied PK-word2vec in a case study of patient portal messages in the Vanderbilt University Medical Center electric health record system sent by patients diagnosed with breast cancer from December 2004 to November 2017. We evaluated the model through a set of 1000 tasks, each of which compared the relevance of a given word to a group of the five most similar words generated by PK-word2vec and a group of the five most similar words generated by the standard word2vec model. We recruited 200 Amazon Mechanical Turk (AMT) workers and 7 medical students to perform the tasks. The dataset was composed of 1389 patient records and included 137,554 messages with 10,683 unique words. Prior knowledge was available for 7981 non-medical and 1116 medical words. In over 90% of the tasks, both reviewers indicated PK-word2vec generated more similar words than standard word2vec (p = 0.01).The difference in the evaluation by AMT workers versus medical students was negligible for all comparisons of tasks' choices between the two groups of reviewers ( p = 0.774 under a paired t-test). PK-word2vec can effectively learn word representations from a small message corpus, marking a significant advancement in processing patient portal messages.

Fertility-preserving treatment for stage IA endometrial cancer: a systematic review and meta-analysis.

OBJECTIVE: The increasing use of fertility-preserving treatments in reproductive-aged patients with early-stage endometrial cancer necessitates robust evidence on the effectiveness of oral progestins and levonorgestrel-releasing intrauterine device. We conducted a systematic review and meta-analysis to examine the outcomes following these 2 primary progestin-based therapies in reproductive-aged patients with early-stage endometrial cancer. DATA SOURCES: We conducted a systematic review of observational studies and randomized controlled trials following the Cochrane Handbook guidance. We conducted a literature search of 5 databases and 1 trial registry from inception of the study to April 16, 2024. STUDY ELIGIBILITY CRITERIA: Studies reporting complete response within 1 year in reproductive-aged patients with clinical stage IA endometrioid cancer undergoing progestin therapy treatment were included. We used data from both observational and randomized controlled studies. STUDY APPRAISAL AND SYNTHESIS METHODS: The primary exposure assessed was the type of progestational treatment (oral progestins or LNG-IUD). The primary outcome was the pooled proportion of the best complete response (CR) within 1 year of primary progestational treatment. We performed a proportional meta-analysis to estimate the treatment response. Sensitivity analyses were performed by removing studies with extreme effect sizes or removing grade 2 tumors. The risk of bias was assessed in each study using the Joanna Briggs Institute critical appraisal checklist. RESULTS: Our analysis involved 754 reproductive-aged patients diagnosed with endometrial cancer, with 490 receiving oral progestin and 264 receiving levonorgestrel-releasing intrauterine device as their primary progestational treatment. The pooled proportion of the best complete response within 12 months of oral progestin and levonorgestrel-releasing intrauterine device treatment were 66% (95% CI, 55-76) and 86% (95% CI, 69-95), respectively. After removing outlier studies, the pooled proportion was 66% (95% CI, 57-73) for the oral progestin group and 89% (95% CI, 75-96) for the levonorgestrel-releasing intrauterine device group, showing reduced heterogeneity. Specifically, among studies including grade 1 tumors, the pooled proportions were 66% (95% CI, 54-77) for the oral progestin group and 83% (95% CI, 50-96) for the levonorgestrel-releasing intrauterine device group. The pooled pregnancy rate was 58% (95% CI, 37-76) after oral progestin treatment and 44% (95% CI, 6-90) after levonorgestrel-releasing intrauterine device treatment. CONCLUSION: This meta-analysis provides valuable insights into the effectiveness of oral progestins and levonorgestrel-releasing intrauterine device treatment within a 12-month timeframe for patients with early-stage endometrial cancer who desire to preserve fertility. These findings have the potential to assist in personalized treatment decision-making for patients.

Efficacy of antiobesity medications among breast cancer survivors taking aromatase inhibitors.

PURPOSE: Aromatase inhibitors (AI) block estrogen synthesis and are used as long-term adjuvant treatment for breast cancer in postmenopausal women. AI use can be associated with weight gain that can lead to increased cardiometabolic risk. The response to anti-obesity medications (AOM) in patients using AI has yet to be studied. We sought to investigate weight loss outcomes of AOM in patients taking AI for breast cancer treatment. METHODS: This is a matched retrospective cohort study of breast cancer survivors on AI using AOM (AOM/AI group). We compared their weight loss outcomes with a group of female patients with obesity, without a history of breast cancer or AI use, on AOM (AOM group). The primary endpoint was total body weight loss percentage (TBWL %) at the last follow-up. We performed mixed linear regression models, including diabetes status at baseline, to assess associations between use of AOM with/without AI with total body weight loss percentage (TBWL%). RESULTS: We included 124 patients: 62 in the AOM/AI group (63.6 ± 10 years, body mass index [BMI] 34.3 ± 7.1 kg/m2) and 62 in the AOM group (62.8 ± 9.9 years, BMI 34.6 ± 6.5 kg/m2). The mean time of follow up was 9.3 ± 3.5 months, with no differences among the two groups. The AOM/AI group had a lower TBWL% compared to the AOM group at the last follow-up -5.3 ± 5.0 vs. -8.2 ± 6.3 (p = 0.005). The results remained significant after adjusting for diabetes status (p = 0.0002). At 12 months, the AOM/AI group had a lower TBWL% compared to the AOM group 6.4 ± 0.8% vs. 9.8 ± 0.9% (p = 0.04). The percentage of patients achieving ≥ 5%, ≥ 10%, and ≥ 15% of weight loss at 12 months was greater in the AOM compared to the AOM/AI group. Although the weight loss response was suboptimal, patients in the AOM/AI group had improvement in fasting glucose, glycated hemoglobin, systolic blood pressure, and low-density lipoprotein cholesterol. CONCLUSIONS: The use of AI in breast cancer survivors is associated with less weight loss response to AOM compared to patients without breast cancer history and who do not take AI. Studies are needed to assess the mechanisms behind the differential weight loss response to AOM in women taking AI.

Retrospective Analysis of Effective Management Strategies for Primary Amenorrhea of Reproductive Age in Saudi Arabia.

Primary amenorrhea, the absence of menstruation by age 15, can have significant implications for reproductive health and overall well-being. This retrospective study aimed to evaluate the effectiveness of various management strategies for primary amenorrhea among women of reproductive age in Saudi Arabia. Medical records of 63 eligible patients from 2018 to 2023 were analyzed, assessing diagnostic methods, treatment modalities, and associated outcomes. The findings revealed that hormonal therapy was the most commonly employed management strategy (50.0%) and demonstrated the highest rate of achieving menstrual regularity (62.5%). Surgical interventions were utilized in 28.1% of cases, with a 50.0% rate of symptom resolution. Lifestyle modifications were less frequent (21.9%) but showed a moderate rate of symptom resolution (35.7%). Logistic regression analysis identified age, underlying etiology, and management strategy as significant predictors of treatment success. Subgroup analyses highlighted the efficacy of hormonal therapy and lifestyle modifications for genetic etiologies, while surgical interventions were more effective for anatomical causes. The study underscores the importance of a comprehensive diagnostic approach and personalized treatment plans tailored to individual patient characteristics. Despite limitations, the findings contribute to the understanding of optimal management strategies for primary amenorrhea and emphasize the need for multidisciplinary collaboration in addressing this complex condition.

Expert Consensus Recommendations on the Management of Treatment-emergent Adverse Events Among Men with Prostate Cancer Taking Poly-ADP Ribose Polymerase Inhibitor + Novel Hormonal Therapy Combination Therapy.

BACKGROUND AND OBJECTIVE: Recent clinical trials have shown improvement in progression-free survival in men with metastatic prostate cancer (mPC) treated with combination poly-ADP ribose polymerase (PARP) inhibitors (PARPi) and novel hormonal therapy (NHT). Regulatory bodies in the USA, Canada, Europe, and Japan have recently approved this combination therapy for mPC. Common adverse events (AEs) include fatigue, nausea and vomiting, and anemia. Nuanced AE management guidance for these combinations is lacking. The panel objective was to develop expert consensus on AE management in patients with mPC treated with the combination PARPi + NHT. METHODS: The RAND/University of California Los Angeles modified Delphi Panel method was used. AEs were defined using the Common Terminology Criteria for Adverse Events. Twelve experts (seven medical oncologists, one advanced practice registered nurse, three urologists, and one patient advocate) reviewed the relevant literature; independently rated initial AE management options for the agent suspected of causing the AE for 419 patient scenarios on a 1-9 scale; discussed areas of agreement (AoAs) and disagreement (AoDs) at a March 2023 meeting; and repeated these ratings following the meeting. Second-round ratings formed the basis of guidelines. KEY FINDINGS AND LIMITATIONS: AoDs decreased from 41% to 21% between the first and second round ratings, with agreement on at least one management strategy for every AE. AoAs included the following: (1) continue therapy with symptomatic treatment for patients with mild AEs; (2) for moderate fatigue, recommend nonpharmacologic treatment, hold treatment temporarily, and restart at a reduced dose when symptoms resolve; (3) for severe nausea or any degree of vomiting where symptomatic treatment fails, hold treatment temporarily and restart at a reduced dose when symptoms resolve; and (4) for hemoglobin 7.1-8.0 g/dl and symptoms of anemia, hold treatment temporarily and restart at a reduced dose after red blood cell transfusion. CONCLUSIONS AND CLINICAL IMPLICATIONS: This expert guidance can support management of AEs in patients with mPC receiving combination PARPi + NHT therapy. PATIENT SUMMARY: A panel of experts developed guidelines for adverse event (AE) management in patients with metastatic prostate cancer treated with a combination of poly-ADP ribose polymerase inhibitors and novel hormonal therapy. For mild AEs, continuation of cancer therapy along with symptomatic treatment is recommended. For moderate or severe AEs, cancer therapy should be stopped temporarily and restarted at the same or a reduced dose when AE resolves.
