Metformin and progestins in women with atypical hyperplasia or endometrial cancer: systematic review and meta-analysis

PURPOSE

To assess metformin's effectiveness in adding it to progestin-based hormone therapy for treating atypical endometrial hyperplasia (AEH) and early endometrial cancer (EEC).

METHODS

We conducted a systematic review and meta-analysis following PRISMA guidelines (registration number CRD42023399094). We searched databases for studies up to March 2023, including randomized and non-randomized clinical trials in English.

RESULTS

Out of 280 studies, 9 studies (1104 patients) were eligible. A total of 408 patients were allocated to receive metformin, and 696 patients entered the control group. Primary analysis focused on evaluating the CR showed a significant difference in patients with AEH treated with metformin (RR = 1.10, 95% CI 1.02-1.20, p = 0.02). Relapse rate (RR = 0.62, 95% CI 0.33-1.17, p = 0.14) was also evaluated. Secondary analysis indicated higher pregnancy rates (RR = 1.28, 95% CI 1.04-1.57, p = 0.02) with no significant difference in live birth rates (RR = 0.56, 95% CI 0.29-1.10, p = 0.09).

CONCLUSION

Combined therapy is effective. Metformin shows superiority to the standard regimen in achieving better CR rate in patients with AEH and benefits pregnancy rates but not recurrence or live birth rates. Therefore, the ideal fertility-sparing treatment for EC has not yet been determined and further clinical trials are needed.

Cronkhite-Canada syndrome with esophagus involvement and six-year follow-up: A case report

BACKGROUND

Cronkhite-Canada syndrome (CCS) is a rare, noninherited disease characterized by gastrointestinal polyposis with diarrhea and ectodermal abnormalities. CCS polyps are distributed through the whole digestive tract, and they are common in the stomach and colon but very uncommon in the esophagus.

CASE SUMMARY

Here, we present a case of a 63-year-old man with skin hyperpigmentation accompanied by diarrhea, alopecia, and loss of his fingernails. Laboratory data indicated anemia, hypoalbuminemia, hypocalcemia, hypokalemia, and positive fecal occult blood. Endoscopy showed numerous polyps scattered throughout the digestive tract, including the esophagus. He was treated with nutritional support and glucocorticoids with remission of his symptoms.

CONCLUSION

Comprehensive treatment led by hormonal therapy can result in partial or full remission of clinical symptoms. Treatment should be individualized for each patient according to their therapy response. Surveillance endoscopy is necessary for assessing mucosal disease activity and detecting malignant transformation.

Effect of strategies to increase progesterone levels on fertility of bovine embryo transfer recipients - A meta-analysis

The pregnancy rate following embryo transfer (ET) is a very important factor in the success of embryo production programs. Different strategies were therefore developed to increase pregnancy rates. The aim of this meta-analysis was to investigate the effects of hormone treatments used to increase the success of embryo transfer programs on pregnancy rates. A meta-analysis was performed of 46 trials from 39 publications involving treated (n = 7856) and control (n = 6663) cattle. The meta-analysis explained the effect size with its 95 % confidence interval (CI) for pregnancy per embryo transfer (P/ET) after hormonal treatment under different moderators. Hormonal support was found to increase P/ET compared to the control group (P < 0.05). However, GnRH treatment was found to increase P/ET by approximately 4.3 % and hCG treatment by 8.0 %. Progesterone supplementation was not found to have a statistically significant effect on P/ET. In addition, GnRH treatment significantly increased P/ET when used to transfer in vitro or frozen-thawed embryos or in studies using cows as recipients. It was observed that hCG treatment had a positive effect on P/ET according to all moderators. Progesterone supplementation significantly increased P/ET when frozen embryos were transferred and reduced P/ET, especially in publications where fresh or in vitro produced embryos were transferred or cows were used as recipients. The results of this meta-analysis showed that the use of GnRH, and hCG, in bovine embryo transfer programs increased P/ET, whereas the use of progesterone had no effect on P/ET. However, it was found that P/ET could increase/decrease depending on the moderator.

Cardiovascular Mortality and Duration of Androgen Deprivation in Locally Advanced Prostate Cancer: Long-term Update of NRG/RTOG 9202

BACKGROUND

Androgen deprivation therapy (ADT) has been associated with coronary heart disease and myocardial infarction (MI) in prostate cancer patients, but controversy persists regarding its effects on cardiovascular mortality (CVM).

OBJECTIVE

We assessed the long-term relationship between ADT and CVM in a prostate cancer randomized trial (NRG Oncology/Radiation Therapy Oncology Group 9202).

DESIGN, SETTING, AND PARTICIPANTS

From 1992 to 1995, 1554 men with locally advanced prostate cancer (T2c-T4, prostate-specific antigen <150 ng/ml) received radiotherapy with 4 mo (short-term [STADT]) versus 28 mo (longer-term [LTADT]) of ADT.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

Using the Fine-Gray and Cox regression models, the relationship between ADT and mortality was evaluated.

RESULTS AND LIMITATIONS

With a median follow-up of 19.6 yr, LTADT was associated with improved overall survival (OS) versus STADT (adjusted hazard ratio [HR] 0.88; p = 0.03) and prostate cancer survival (subdistribution HR [sHR] 0.70, p = 0.003). Comparing LTADT with STADT, prostate cancer mortality improved by 6.0% (15.6% [95% confidence interval 13.0-18.3%] vs 21.6% [18.6-24.7%]) at 15 yr, while CVM increased by 2.2% (14.9% [12.4-17.6%] vs 12.7% [10.4-15.3%]). In multivariable analyses, LTADT was not associated with increased CVM versus STADT (sHR 1.22 [0.93-1.59]; p = 0.15). An association between LTADT and MI death was detected (sHR 1.58 [1.00-2.50]; p = 0.05), particularly in patients with prevalent cardiovascular disease (CVD; sHR 2.54 [1.16-5.58]; p = 0.02).

CONCLUSIONS

With 19.6 yr of follow-up, LTADT was not significantly associated with increased CVM in men with locally advanced prostate cancer. Patients may have increased MI mortality with LTADT, particularly those with baseline CVD. Overall, there remained a prostate cancer mortality benefit and no OS detriment with LTADT.

PATIENT SUMMARY

In a long-term analysis of a large randomized prostate cancer trial, radiation with 28 mo of hormone therapy did not increase the risk of cardiovascular death significantly versus 4 mo of hormone therapy. Future studies are needed for patients with pre-existing heart disease, who may have an increased risk of myocardial infarction death with longer hormone use.

European Society of Cardiology Core Curriculum for cardio-oncology

Cardio-oncology is a rapidly growing field of cardiovascular (CV) medicine that has resulted from the continuously increasing clinical demand for specialized CV evaluation, prevention and management of patients suffering or surviving from malignant diseases. Dealing with CV disease in patients with cancer requires special knowledge beyond that included in the general core curriculum for cardiology. Therefore, the European Society of Cardiology (ESC) has developed a special core curriculum for cardio-oncology, a consensus document that defines the level of experience and knowledge required for cardiologists in this particular field. It is structured into 8 chapters, including (i) principles of cancer biology and therapy; (ii) forms and definitions of cancer therapy-related cardiovascular toxicity (CTR-CVT); (iii) risk stratification, prevention and monitoring protocols for CTR-CVT; (iv) diagnosis and management of CV disease in patients with cancer; (v) long-term survivorship programmes and cardio-oncology rehabilitation; (vi) multidisciplinary team management of special populations; (vii) organization of cardio-oncology services; (viii) research in cardio-oncology. The core curriculum aims at promoting standardization and harmonization of training and evaluation in cardio-oncology, while it further provides the ground for an ESC certification programme designed to recognize the competencies of certified specialists.

Nonsurgical management of early-stage endometrial cancer due to obesity: a survey of the practice patterns of current Society of Gynecologic Oncology members

Objective

Nonsurgical management for endometrial cancer in patients with class 3 obesity (BMI ≥ 40 kg/m2) is a challenging scenario given lack of consensus on patient selection and treatment options. Our objective was to evaluate trends in practice patterns and physician opinions in the Society of Gynecologic Oncology (SGO) on nonsurgical management of endometrial cancer and complex atypical hyperplasia due to obesity.

Methods

An online survey was sent to all gynecologic oncologist members of the SGO with questions centered on decision-making for nonsurgical approaches for patients with class 3 obesity patients. Fisher's exact tests were used to assess the associations between offering nonsurgical management and geographic region, practice type, and time in practice.

Results

255 (19.8 %) members from 6 geographic regions responded, of which 183 (71.8 %) offered primary nonsurgical management of endometrial cancer to patients with class 3 obesity and 72 (28.2 %) do not. The choice to offer initial nonsurgical management did not vary based on geographic region, time in practice or practice type. When asked to select BMI cutoff, the majority (65.2 %) started to offer nonsurgical management was BMI 60-64 kg/m2. Progesterone intrauterine device was the preferred treatment (68.3 %, 125/183). Of those who offered nonsurgical management, 97.3 % (178/183) recommended resampling in 3-6 months.

Conclusion

Primary nonsurgical management of endometrial cancer in patients with class 3 obesity is offered by most gynecologic oncologists in SGO. However, almost one-third of gynecologic oncologists indicated they do not offer nonsurgical management for endometrial cancer for obesity alone. Additional data are needed to determine the safety of both approaches in these complex patients.

Sleep During Menopause

Postmenopause is defined retrospectively after 12 consecutive months of amenorrhea. It represents the end of the reproductive period and ovarian failure. A decrease in estrogen leads to several changes in the short and long term. Among the early changes, vasomotor symptoms (hot flashes) are particularly common, occurring in about 70% of women. In addition, there are changes in mood, anxiety, depression, and insomnia. Insomnia occurs in almost 60% of postmenopausal women. Psychosocial aspects may also affect sleep. Proper diagnosis may lead to adequate treatment of sleep disturbances during menopause. Hormonal or other complementary therapies can improve sleep quality.

Cardiovascular Adverse Events Associated With New-Generation Androgen Receptor Pathway Inhibitors (ARPI) for Prostate Cancer: A Disproportionality Analysis Based on the FDA Adverse Event Reporting System (FAERS)

BACKGROUND

The potential cardiovascular adverse events associated with new-generation androgen receptor pathway inhibitors (ARPI) in the treatment of prostate cancer remain unclear. We aimed to assess the pharmacovigilance (PV), reporting rate, severity, and reaction outcomes of major adverse cardiovascular events (MACE) related to new-generation ARPI for prostate cancer reported to the United States Food and Drug Administration Adverse Event Reporting System (FAERS).

METHODS

We analyzed reports of cardiovascular adverse events associated with drug therapy for prostate cancer submitted to FAERS between January 2014 and December 2022. Three primary new-generation ARPIs were identified: abiraterone acetate, enzalutamide, and apalutamide. Our primary composite endpoint was the PV of MACE caused by ARPIs in the treatment of prostate cancer, and the secondary endpoint was PV of other cardiovascular events. The software implemented was STATA 17.0 MP.

RESULTS

A total of 278,031 suspected drug-adverse event pairs related to drug treatment in patients with prostate cancer were identified, of which 10,861 reports were cardiovascular events, including 5800 reports of MACE and 5061 reports of other cardiovascular events. The majority of these cardiovascular adverse event reports came from the United States (36.6%) and were mostly older men (age 76.0 ± 8.6 years). Compared with enzalutamide, the constituent ratio of MACE caused by abiraterone acetate and apalutamide was significantly increased, but the incidence of severe MACE decreased significantly. The PV signal regarding MACE was detected in abiraterone acetate and apalutamide but not in enzalutamide.

CONCLUSION

Abiraterone acetate and apalutamide presumably are associated with a higher risk of MACE than enzalutamide in new-generation ARPI for prostate cancer. More extensive prospective studies and more extended follow-up periods need to confirm this further.

Differential outcomes and immune checkpoint inhibitor response among endometrial cancer patients with MLH1 hypermethylation versus MLH1 "Lynch-like" mismatch repair gene mutation

OBJECTIVES

To identify differential survival outcomes and immune checkpoint inhibitor (ICI) response in MLH1 hypermethylated versus MLH1 mutated ("Lynch-like") endometrial tumors and determine whether their molecular profiles can elucidate the differential outcomes.

METHODS

1673 mismatch repair deficient endometrial tumors were analyzed by next-generation sequencing and whole transcriptome sequencing (Caris Life Sciences, Phoenix, AZ). PD-L1, ER, and PR were tested by immunohistochemistry and immune cell infiltrates were calculated using MCP-counter. Significance was determined using Chi-square and Mann-Whitney U tests and adjusted for multiple comparisons. Overall survival (OS) was depicted using Kaplan-Meier survival curves.

RESULTS

The endometrial cancer cohort comprised 89.2% patients with MLH1 hypermethylated tumors and 10.8% with MLH1 mutated tumors, with median ages of 67 and 60 years, respectively (p < 0.01). Patients with MLH1 hypermethylated tumors had significantly worse OS and trended toward worse OS following ICI treatment than patients with MLH1 mutated tumors. The immune microenvironment of MLH1 hypermethylated relative to MLH1 mutated was characterized by decreased PD-L1 positivity, immune checkpoint gene expression, immune cell infiltration, T cell inflamed scores, and interferon gamma (IFNγ) scores. MLH1 hypermethylation was also associated with decreased mutation rates in TP53 and DNA damage repair genes, but increased rates of JAK1, FGFR2, CCND1, and PTEN mutations, as well as increased ER and PR positivity.

CONCLUSIONS

Endometrial cancer patients with MLH1 hypermethylation display significantly decreased survival and discrepant immunotherapy responses compared to patients with MLH1 mutated tumors, which was associated with differential mutational profiles, a more immune cold phenotype, and increased ER/PR expression in MLH1 hypermethylated tumors. Providers may consider early transition from single agent ICI to a multi-agent regimen or hormonal therapy for patients with MLH1 hypermethylated tumors.

Topical estrogens for the treatment of superficial dyspareunia related to genitourinary syndrome of menopause in women with a history of endometriosis: A clinical dilemma

Estrogen withdrawal, which occurs with the cessation of ovulation, causes genitourinary syndrome of menopause in up to 50-85% of women. Symptoms may profoundly impact quality of life and sexual function, interfering with enjoyment of sex in up to three out of four individuals. Topical estrogens have been found to provide symptom relief with minimal systemic absorption and appear to be superior to systemic therapy as what regards genitourinary symptoms. However, conclusive data on their appropriateness in postmenopausal women with a history of endometriosis is not available and the hypothesis that exogenous estrogen stimulation may reactivate endometriotic foci or even promote their malignant transformation is still open. On the other hand, endometriosis affects around 10% of premenopausal women, many of which may be exposed to an acute hypoestrogenic depletion even before spontaneous menopause occurs. This considered, excluding on principle patients with a history of endometriosis from first-line treatment for vulvovaginal atrophy would mean excluding a considerable percentage of the population from adequate care. More robust evidence is urgently needed in these regards. Meanwhile, it would appear reasonable to tailor the prescription of topical hormones in these patients, taking into account the entity of symptoms and the impact such symptoms have on patients' quality of life, as well as the form of endometriosis and the possible risks hormonal may entail. Moreover, the application of estrogens on the vulva instead of the vagina could be efficacious, while outweighing the possible biological cost of hormonal treatment in women with a history of endometriosis.

Liver Pathology Related to Onco-Therapeutic Agents

Oncotherapeutic agents can cause a wide range of liver injuries from elevated liver functions tests to fulminant liver failure. In this review, we emphasize a newer generation of drugs including immune checkpoint inhibitors, protein kinase inhibitors, monoclonal antibodies, and hormonal therapy. A few conventional chemotherapy agents are also discussed.

Cancer-related post-treatment pain and its impact on treatment satisfaction with medication in women with breast cancer: a cross-sectional study from Palestine

BACKGROUND

Pain after therapy is an important clinical problem in patients with breast cancer. Unfortunately, cancer patients have a lower quality of life due to inadequate treatment of posttreatment pain; therefore, improving medication management plans and palliative care has become one of the most important targets of cancer therapy. Therefore, the current study aimed to examine the impact of posttreatment pain on medication satisfaction in patients with various stages of breast cancer in Palestine.

METHODS

A cross-sectional analytical study was conducted et al.-Watani Hospital and An-Najah National University Hospital in the Nablus area. Using the Brief Pain Inventory (BPI), the intensity and interference of pain were evaluated. In addition, patients' satisfaction with cancer management medications was measured using the Treatment Satisfaction Questionnaire for Medication (TSQM).

RESULTS

Two hundred fifty-four patients were included in this study. All were women, with a mean ± SD age of 53.1 ± 10.7 years. The median score for pain severity was 7.0. Pain in the lower extremities was the most reported location. There was a negative association between the global satisfaction domain and the presence of posttreatment pain (p < 0.001). Furthermore, significant differences and negative correlations were found between global satisfaction and posttreatment pain on the day of the interview (p = 0.001), pain medication (p < 0.001), paracetamol use (p < 0.001), and the presence of side effects (p = 0.003). There were significant negative correlations (p < 0.05) between pain severity and interference with effectiveness (r = -0.258, -0.319, respectively), side effects (r = -0.414, -0.514, respectively), convenience (r = -0.274, -0.307, respectively), and global satisfaction domain scores (r = -0.293, -0.287, respectively). Exposure to chemotherapy was the only significant positive correlation with global satisfaction (p = 0.007). The regression analysis results indicated an independent association between chemotherapy use and a higher global satisfaction score (p = 0.011).

CONCLUSIONS

Patients with posttreatment pain, side effects, and greater interference of pain with their functioning had lower satisfaction scores. Therefore, better management of their treatment medications, side effects, and pain medications is recommended to enhance their satisfaction and quality of life. Several aspects of palliative care should be organized to improve the patient's satisfaction and quality of life in addition to conducting longitudinal studies to evaluate the pain and satisfaction of different types of cancers.

Nutritional vitamin B12 deficiency-associated Infantile epileptic spasms syndrome: Clinico-neurophysiological presentation, response to treatment, and neurodevelopmental outcome

INTRODUCTION

Nutritional vitamin B12 deficiency has been shown to cause Infantile epileptic spasms syndrome (IESS) in infants in anecdotal studies.

METHODS

In this retrospective cohort study, we intended to study the clinical presentation, neurophysiological, laboratory abnormalities, treatment, and neurodevelopmental outcome at 6-months in infants presenting with IESS secondary to nutritional vitamin B12 deficiency (NVBD) and to compare these variables from the rest of the infants with IESS without vitamin B12 deficiency. We included only spasm-free cases or those who showed at least a 50% reduction in spasm frequency on D7 after starting oral/parenteral vitamin B12. We used well-validated measurement tools like the Developmental Assessment Scale for Indian Infants (DASII), Child Feeding Index (CFI), Burden of amplitudes and epileptiform discharges (BASED) score, countable Hypsarrhythmia paroxysm index (cHPI), durational Hypsarrhythmia paroxysm index (dHPI), and Early childhood epilepsy severity scale (E-CHESS) score for documenting these variables.

RESULTS

Data from 162 infants with IESS (21 caused by NVBD) were included in our study. The NVBD group had more patients residing in the rural region, with lower socioeconomic status, vegetarian mothers and poor complementary feeding index (p<0.001 for all). The NVBD group also had less number of patients requiring antiseizure medications (ASMs) and hormonal therapy(p<0.001), remained seizure free at six months (p=0.008), lower number of clusters per day (p=0.02) and the number of spasms per clusters at presentation (p=0.03), lower BASED score (p=0.03) and cHPI, dHPI at presentation (p<0.001). All of them remained spasm-free, with normal electroencephalogram at 6-months. Development quotient at baseline, at 6-months, and improvement in development quotient between these two-time points were more in the vitamin B12 deficiency group (p<0.001). All of them had clinical features of pre-ITS (infantile tremor syndrome) or ITS and it was found to be the only independent predictor of NVBD in infants with IESS. Mothers of all these infants had low serum vitamin B12 levels (<200 pg/ml).

CONCLUSIONS

Nutritional vitamin B12 deficiency may cause IESS in infants. Hence, vitamin B12 deficiency needs to be ruled out in patients with IESS without any definite etiology.

Impact of 18F-fluciclovine PET/CT on plans for androgen deprivation therapy in patients with biochemical recurrence of prostate cancer: data analysis from two prospective clinical trials

INTRODUCTION

Despite early detection and primary therapy improvements, biochemical recurrence (BCR) of prostate cancer remains common. The advent of highly sensitive molecular imaging has facilitated identification of men with limited metastatic disease burden that might be more optimally treated with metastases-directed therapy than with androgen deprivation therapy (ADT). The LOCATE (NCT02680041) and FALCON (NCT02578940) trials assessed the impact of 18F-fluciclovine PET/CT on the management of patients with BCR after curative-intent primary therapy. We performed a secondary analysis of LOCATE and FALCON data to characterize sites of recurrence and management decisions for BCR patients who had an intended management plan including ADT prior to undergoing 18F-fluciclovine PET/CT.

METHODS

Data from 317 LOCATE/FALCON patients who underwent 18F-fluciclovine PET/CT were analyzed and those with a prescan plan for ADT (± another treatment) were selected. 18F-Fluciclovine detection rates were determined at the patient level and for the prostate/prostate bed region, pelvic and extra-pelvic lymph nodes (LN), soft tissues, and bones. The patients' pre- and postscan treatment plans were compared and were stratified by imaging results.

RESULTS

A total of 146 patients had a prescan plan for ADT (60 as monotherapy and 86 in combination with another modality). 18F-Fluciclovine detected lesions in 85 of 146 (58%) patients planned for ADT. Detection rates in the prostate/bed, pelvic LN, extra-pelvic LN, soft tissues and bone were 30%, 25%, 13%, 2.1%, and 13%, respectively. Twenty-five (17%) patients had positivity confined to the prostate/bed, 21 (14%) had 18F-fluciclovine-positive pelvic LN (±prostate/bed) but no other involvement and 39 (27%) had involvement outside the prostate/bed and pelvic LN. Postscan, 93 of 146 (64%) patients had a management change, 55 (59%) of which were to abort ADT. Only 25% of the patients originally planned for ADT monotherapy still had an unaltered plan for ADT monotherapy postscan. Patients with a postscan plan for ADT monotherapy had the most disseminated disease. Disease in the prostate/bed only was most common in those whose plan was altered to abort ADT.

CONCLUSIONS

18F-Fluciclovine-PET/CT influenced management plans for the majority of patients with a prescan plan for ADT. Plans were commonly amended to target salvage therapy for lesions identified with 18F-fluciclovine PET/CT, and consequently likely spared/delayed patients the morbidity associated with ADT.

Casein kinase 1 controls the shuttling of epidermal growth factor receptor and estrogen receptor in endometrial carcinoma induced by breast cancer hormonal therapy: Relevance of GPER1/Src

Casein kinase 1 plays a crucial role in carcinogenesis. 4-Hydroxytamoxifen (4-OHT), which is widely used to treat breast cancer, often leads to the development of endometrial carcinoma with poor prognosis, particularly among women who receiving long-term treatment. This study was performed to elucidate whether specific inhibition of casein kinase 1 (CK1) controls 4-OHT-mediated Ishikawa cell carcinogenesis. 4-OHT significantly stimulated the activity of estrogen receptor alpha (ERα) and nuclear translocation and expression of epidermal growth factor receptor (EGFR) from the plasma membrane to perinuclear or nuclear regions, as well as the activities of G-protein-coupled estrogen receptor 1 (GPER1) and Src in Ishikawa cells. However, inhibition of EGFR by Gefitinib blocked all these events, and inhibition of GPER1 or Src produced a partial block. GPER1 and Src controlled Ishikawa cell carcinogenesis in different manners: GPER1 accelerated EGFR mobility without affecting ERα activity, while Src activated ERα and EGFR without any change in GPER1 expression. EGFR and GPER1 performed reciprocal regulation in endometrial cell carcinogenesis via direct interaction in 4-OHT-treated Ishikawa cells, implying a possible key role of GPER1 in these events. Inhibition of CK1 by CKI-7 and IC261, however, impeded all changes beginning with EGFR translocation and activity in 4-OHT-treated Ishikawa cells. These findings indicate that inhibition of CK1 could control 4-OHT-mediated activation and translocation of ER/EGFR and GPER1/Src expression, inhibiting 4-OHT-triggered endometrial carcinogenesis. Therefore, targeting of CK1 by CKI-7 and IC261 could be a prospective adjuvant therapy for breast cancer patients taking tamoxifen.

Metformin, placebo, and endocrine therapy discontinuation among participants in a randomized double-blind trial of metformin vs placebo in hormone receptor-positive early-stage breast cancer (CCTG MA32)

BACKGROUND

The MA32 study investigated whether 5 years of metformin (versus placebo) improves invasive disease-free survival in early-stage breast cancer (BC). Non-adherence to endocrine therapy (ET) and medications for chronic conditions is common and increases with drug toxicity and polypharmacy. This secondary analysis evaluates rates and predictors of early discontinuation of metformin, placebo, and ET among participants with HR-positive BC.

METHODS

Patients with high-risk non-metastatic BC were randomized to 60 months of metformin (850 mg BID) or placebo BID. Patients were administered bottles of metformin/placebo every 180 days. Metformin/placebo adherence was defined as a bottle dispensed at month 48 or later. The ET adherence analysis included patients with HR-positive BC who received ET with start and stop date reported, with adherence defined as > 48 months of use. Associations of covariates with study drug and ET adherence were examined using multivariable models.

RESULTS

Among the 2521 HR-positive BC patients, 32.9% were non-adherent to study drug. Non-adherence was higher among patients on metformin vs placebo (37.1% vs 28.7%, p < 0.001). Reassuringly, ET discontinuation rates were similar between treatment arms (28.4% vs 28.0%, p = 0.86). Patients who were non-adherent to ET were more likely to discontinue study therapy (38.8% vs 30.1%, p < 0.0001). In a multivariable analysis, study drug non-adherence was increased with metformin vs placebo (OR: 1.50, 95% CI 1.25-1.80; p < 0.0001); non-adherence to ET (OR: 1.47, 95% CI 1.20-1.79, p < 0.0001); grade 1 or greater GI toxicity during the first 2 years; lower age; and higher body mass index.

CONCLUSION

While non-adherence was higher among patients on metformin, it was still considerable among patients on placebo. Reassuringly, treatment arm allocation did not impact ET adherence. Attention to global medication adherence is needed to improve BC and non-oncological outcomes in cancer survivors.

Adherence to adjuvant tamoxifen and associated factors in breast cancer survivors

PURPOSE

Adjuvant endocrine therapy reduces the recurrence and mortality of early hormone receptor-positive breast cancer in both pre- and postmenopausal women. The aim of this study was to investigate adjuvant tamoxifen adherence and associated factors in breast cancer survivors.

METHODS

This descriptive, prospective study was conducted in 2019-2020 with the participation of 531 women who survived breast cancer and were under follow-up at the Senology Institute of a hospital in Istanbul. Inclusion criteria were having completed treatment for early hormone receptor-positive breast cancer, being prescribed tamoxifen, and being 18 years or older. Data were collected using a patient information form and the Morisky Medication Adherence Scale-8 (MMAS-8).

RESULTS

The mean age of the participants was 44.9 ± 6.5 years, and the mean duration of tamoxifen use was 834.4 ± 685.7 days. The women's mean MMAS-8 score was 6.86 ± 1.39. Medication adherence was significantly positively correlated with current age (p = 0.006) and age at diagnosis (p = 0.002). There was a statistically significant difference between tamoxifen adherence according to participants' employment status (p = 0.028), chronic disease status (p = 0.018), loss of libido (p = 0.012), treatment-related changes in mood changes (p = 0.004), and having negative effects affecting daily life (p < 0.001).

CONCLUSION

Overall, breast cancer survivors in this study reported moderate adherence to tamoxifen. The women's individual characteristics and the adverse effects of treatment influenced medication adherence. Healthcare professionals can help increase adherence to this treatment, which reduces the risk of mortality, by explaining the importance of the medication, identifying and eliminating barriers to adherence, and informing women about evidence-based interventions to increase medication compliance.

Effect of menopause and age on vascular impairment

AIMS

The prevalence of cardiovascular diseases increases in women after menopause. The aim of the study was to determine the impact of conventional cardiovascular risk factors such as age, blood pressure, smoking, cholesterol, obesity, and glucose balance, but also menopausal state and sleep-disordered breathing on vascular impairment during menopausal transition.

METHODS

89 women initiated the study and 74 of them participated in the 10-year follow-up. Cardiovascular disease risk factor assessments, ultrasound measurements of brachial artery function, including nitroglycerin-mediated vasodilatation and flow-mediated endothelium-dependent vasodilation, and sleep studies were repeated at baseline and at 5-year and 10-year follow-ups.

RESULTS

Over the study period, all the cardiovascular disease risk estimates increased. Both flow-mediated endothelium-dependent vasodilatation (decline 55 %) and nitroglycerin-mediated vasodilatation (decline 18 %) worsened over the 10 years (p < 0.001). Vascular function was not associated with menopausal state (determined with follicle stimulating hormone). Systolic blood pressure (p = 0.009) and smoking (p = 0.006) at baseline were negatively associated with nitroglycerin-mediated vasodilatation at 5-year follow-up and the use of hormonal therapy at 5-year follow-up was positively associated with concurrent nitroglycerin-mediated vasodilatation (p = 0.041). Intermittent nocturnal hypoxemia at baseline was associated with flow-mediated endothelium-dependent vasodilatation at 10-year follow-up (p = 0.043). High body mass index and impaired glucose balance at 5-year follow-up were associated with nitroglycerin-mediated vasodilatation decline at 10-year follow-up (p = 0.022 and p = 0.037, respectively).

CONCLUSIONS

We demonstrate how cardiovascular risk factors and vascular function evolve during menopausal transition. Although menopause was not associated with vascular impairment, short-term improvement in vascular function was observed in those using menopausal hormonal therapy. Intermittent nocturnal hypoxemia, obesity and impaired glucose control are early predictors of vascular decline during postmenopause.

Male infertility and gonadotropin treatment: What can we learn from real-world data?

Gonadotropin therapy to treat specific male infertility disorders associated with hypogonadotropic hypogonadism is evidence-based and effective in restoring spermatogenesis and fertility. In contrast, its use to improve fertility in men with idiopathic oligozoospermia or nonobstructive azoospermia remains controversial, despite being widely practiced. The existence of two major inter-related pathways for spermatogenesis, including FSH and intratesticular testosterone, provides a rationale for empiric hormone stimulation therapy in both eugonadal and hypogonadal males with idiopathic oligozoospermia or nonobstructive azoospermia. Real-world data (RWD) on gonadotropin stimulating for these patient subsets, mainly using human chorionic gonadotropin and follicle-stimulating hormone, accumulated gradually, showing a positive therapeutic effect in some patients, translated by increased sperm production, sperm quality, and sperm retrieval rates. Although more evidence is needed, current insights from RWD research indicate that selected male infertility patients might be managed more effectively using gonadotropin therapy, with potential gains for all parties involved.

Appropriateness and complications of androgen deprivation therapy for prostate cancer: Can we do better? A retrospective observational analysis from a referral center

INTRODUCTION

Androgen deprivation therapy (ADT) is the key of medical treatment for advanced prostate cancer (PCa), especially in elderly patients. However, the adherence of ADT prescription to current guidelines is not optimal and must be balanced against possible side effects. Aim of this study was to evaluate the prescriptive appropriateness of ADT and ADT-related adverse events in a referral center for PCa.

METHODS

Five hundred fifty six patients who received an outpatient prescription for ADT from 2014 to 2018 were retrospectively identified from an administrative database. Only standard ADT was considered, including GnRH agonists, GnRH antagonists, and antiandrogens. Prescriptive appropriateness was defined according to the last European Association of Urology (EAU) guidelines. Our cohort was stratified according to age categories and patient follow-up was updated.

RESULTS

Four hundred twenty five patients were available for analysis. Mean age was 80 years; 96.3% of our patients fell in the "elderly" category. There was a predominance of GnRH agonists over the antagonists (84.9% vs 13%). 15.5% of ADTs did not have an appropriate indication according to guidelines. Patient compliance to ADT was evaluated as good in 372 (87.5%) cases. ADT-related complications were detected in 166 (39%) patients: bone, cardiovascular, and other complications were reported in 7.3%, 8.9%, and 19% of patients. Progression of disease was noted in 165 (38.8%) cases during ADT. At last follow-up, 124 (30.1%) patients were deceased.

CONCLUSIONS

In a referral center, most ADT prescriptions followed EAU guidelines, but a non-negligible proportion still did not fall within these indications, exposing patients to unnecessary side effects. Compliance to ADT was generally good with a predominant use of GnRH agonists. Tolerance to ADT was fair, even if standardized reports were lacking.

Introduction and Overview of Cancer Therapeutics

Cancer is a complex disease. According to the Globocan survey, 63% deaths are due to cancer. There are some conventional methods that are used to treat cancer. However, certain treatment modalities are under clinical trials still. The success of treatment depends on type and stage of cancer, locality, and patient's response to that specific treatment. Most widely used treatments are surgery, radiotherapy, and chemotherapy. Personalized treatment approach has some promising effects, yet some of the points are still unclear. This chapter has provided the overview of some of the therapeutic modalities; however, the therapeutic potential has been discussed in details throughout the book.

Potential New Approaches for Prostate Cancer Management in Resource-Limited Countries in Africa

Prostate cancer is a major male malignancy in many sub-Saharan countries in Africa. Because of resource limitations, screening, early detection, diagnosis, and curative treatments are not available for many men on the subcontinent, and there are even barriers to the treatment of advanced-stage metastatic prostate cancer. We are making the case for new approaches to the detection, diagnosis, and treatment of this malignancy in sub-Saharan Africa and other low-resource regions-approaches that differ from the ones available and used in high-income countries. The development of one-step dipstick-type detection assays of serum prostate-specific antigen (PSA) offers an approach to prostate cancer detection, treatment and monitoring that circumvents issues related to laboratory quality control and is also low-cost. Curative-intent treatments of early-stage prostate cancer are often unavailable in low-resource contexts, and most prostate cancers are not detected in Africa until they are at an advanced stage. Hence, androgen deprivation treatments, including orchiectomy and older low-cost drugs, offer feasible and affordable approaches to prolong survival and sustain a reasonable quality of life. However, clinical trials are needed to identify which of these androgen deprivation treatments are most efficacious and best tolerated to make progress in providing medical care for men with prostate cancer in sub-Saharan Africa and other low- and lower-middle-income areas around the world.

A case series of triplet anti-hormonal therapy in androgen receptor-positive recurrent adult ovarian granulosa cell tumor

Therapeutic options for recurrent adult granulosa cell tumors (AGCT) are limited. After examining the hormonal pathways involved in FOXL2-mutated granulosa cell tumor development, a novel treatment regimen was utilized for recurrent AGCT: a combination of an androgen receptor antagonist, a gonadotropin-releasing hormone receptor agonist, and an aromatase inhibitor for hormonal blockade. In this case series, seven patients at our institution were treated with bicalutamide 50 mg orally once daily, Leuprolide acetate 7.5 mg intramuscular (IM) injection every 4 weeks, and a daily oral aromatase inhibitor. These patients had recurrent AGCT with androgen receptor positive tumors and had failed prior aromatase inhibitor therapy. All patients had undergone multiple surgical resections and many cycles of chemotherapy. Patients were monitored for toxicities and for response to treatment. Of the seven patients receiving the triple therapy, six saw clinical benefit. Two patients demonstrated a partial response and four patients had stable disease. One patient had progressive disease on the regimen. For the two patients who had a partial response to the triple therapy, there was strong expression of the androgen receptor (AR) noted on tumor immunohistochemistry. This drug combination was well-tolerated except for severe hot flashes in one patient. In conclusion, the triple therapy combination of an androgen receptor antagonist, aromatase inhibitor, and GnRH agonist demonstrated measurable responses in patients with recurrent AGCTs after multiple previous treatments. A prospective clinical trial is planned to further investigate these findings.

Evaluation of Trends in Treatment of Metastatic Hormone Sensitive Prostate Cancer (mHSPC) Across Canada During the COVID-19 Pandemic

BACKGROUND

In metastatic hormone sensitive prostate cancer (mHSPC), treatment intensification with either docetaxel or an androgen-receptor-axis targeted therapy (ARAT), added to androgen deprivation therapy (ADT) is the new standard of care. To better understand patterns of treatment intensification in Canada and specifically how it has been influenced by the COVID-19 pandemic, we conducted a national survey of genitourinary medical oncologists from across Canada.

METHODS

Using SurveyMonkey, we conducted an online survey of 119 medical oncologists in Canada from January 15 to January 27, 2021. The survey consisted of 16 questions, including demographics, and asked specifically about their approach to managing mHSPC before and during the pandemic.

RESULTS

Overall there were 50/119 (42%) respondents. Most were male (65%), from Ontario (35%), practicing in academic centers (71%), with 45% reporting their practices focused primarily on genitourinary malignancies and one other tumor site. The majority were in practice 1 to 5 years (34%). Overall 65% indicated their practice patterns had changed since the pandemic, with 51% offering more ARATs and less docetaxel chemotherapy. In low volume mHSPC, the use of ARATs increased from 73% to 79%, while the use of docetaxel remained unaltered at 2%. In high volume disease, the use of ARATs increased from 63% to 84%, while the use of docetaxel decreased from 37% to 14%. Use of granulocyte colony stimulating factor (G-CSF) with docetaxel chemotherapy increased by 35%. Post-pandemic, 45% reported they intend to maintain these changes. Only 18% reported they had prostate cancer patients test positive for COVID-19, and all patients recovered.

CONCLUSION

Management of patients with mHSPC in Canada has changed during the pandemic, with increased uptake of ARATs and reduced use of docetaxel, a trend expected to continue beyond the pandemic. How this trend will impact uptake of triplet therapy (ADT + ARAT + Docetaxel), downstream treatment choices and overall outcomes remains to be seen.

Thoracic endometriosis masquerading as Meigs' syndrome in a young woman: A case report and literature review

Thoracic endometriosis is an exceedingly rare condition characterized by the presence of endometriotic deposits on the diaphragm, lungs or pleural space. Patients may present with massive hemothorax, pneumothorax, hemoptysis or pulmonary nodules. It is a complex condition that often proves to be a diagnostic challenge, resulting in under-diagnosis, delays in treatment and significant morbidity in women of reproductive age. We report a case of endometriosis causing massive pleural effusion and ascites, with a left adnexal fibroid mass mimicking Meigs' syndrome in a nulliparous woman in her late 30s. The patient was successfully managed with hormonal therapy following fertility-sparing surgical treatment. This case highlights the diagnostic and therapeutic challenges associated with thoracic endometriosis because of its close resemblance to more sinister gynecological conditions. Hormonal therapy is the long-term treatment of choice in patients with thoracic endometriosis to reduce the risk of symptom recurrence and preserve fertility.

•

The most common presentation of thoracic endometriosis is catamenial pneumothorax followed by catamenial hemothorax.

•

Thoracic endometriosis should be considered in a woman presenting with a haemothorax and other stigmata of endometriosis

•

Although video-assisted thoracoscopy provides a definitive diagnosis, thoracic endometriosis can be diagnosed clinically.

•

Hormonal therapy is the mainstay of treatment to control symptoms, reduce recurrence and preserve fertility.

Impact of cytochrome P450 2D6 polymorphisms on decision-making and clinical outcomes in adjuvant hormonal therapy for breast cancer

BACKGROUND

There are concerns that tamoxifen is less effective in Asian women because of the high prevalence of impaired function cytochrome P450 2D6 (CYP2D6) polymor-phisms.

AIM

To evaluate how knowledge of CYP2D6 genotype impacted the choice of hormonal agent and how CYP2D6 genotype and agent were associated with clinical outcomes.

METHODS

Eighty-two women were recruited. Seventy-eight completed CYP2D6 genotyping and were categorized into poor, intermediate (IM) and extensive or ultra metabolizer phenotypes. Women with poor metabolizer and IM phenotypes were recommended aromatase inhibitors as the preferred agent.

RESULTS

More than 70% of the women had an IM phenotype, 32% an extensive or ultra metabolizer phenotype, and 0% had a poor metabolizer phenotype. Regardless of genotype, more women opted for aromatase inhibitors. Overall, 80% of women completed 5 years of hormonal therapy. Five women developed recurrence, 3 contralateral breast cancer, 5 died, and 1 was diagnosed with a second primary cancer. Five-year recurrence-free and overall survival were slightly better in women with the extensive or ultra metabolizer phenotype compared to those with the IM phenotype, though not statistically significant [P = 0.743, hazard ratio (HR): 1.441, 95% confidence interval (CI): 0.191 to 10.17 and P = 0.798, HR: 1.327, 95%CI: 0.172 to 9.915, respectively]. Women receiving aromatase inhibitors also appeared to have a better, but also nonsignificant, 5-year recurrence-free and overall survival (P = 0.253, HR: 0.368, 95%CI: 0.031 to 0.258 and P = 0.292, HR: 0.252, 95%CI: 0.005 to 4.951, respectively).

CONCLUSION

The IM phenotype was highly prevalent but was not associated with clinical outcome.

combined hormonal therapy on fertility of patients with cryptorchidism: results of a longitudinal cohort study

BACKGROUND

To investigate in a longitudinal cohort study, the best treatment to preserve fertility in cryptorchid subjects. Patients treated with immediate hormonal vs. delayed vs. combined (hormone plus surgery) therapy consecutively enrolled during the period 1987-1997, were evaluated.

METHODS

Two hundred fifty-five subjects were enrolled and 192 patients completed the follow-upt. One hundred fifty-six patients and 36 out 192 had monolateral and bilateral cryptorchidism, respectively. Twenty-nine out of 192 were previously treated by surgery alone (Group A), 93/192 by hormone therapy alone (Group B), 51/192 received sequential combined hormone therapy plus surgery (Group C) whilst 19/192 refused any type of treatment (Group D). The other 63 patients were considered lost to follow-up. All the patients underwent medical consultation, scrotal ultrasound scan, sperm analysis and Inhibin B, Follicular Stimulating Hormone (FSH) and Testosterone (T) serum level determination.

RESULTS

Testicular volume was found decreased in the Group D patients whilst hormone serum levels were comparable in all groups. Statistically significant differences for sperm characteristics were found in patients treated with hormonal therapy alone or combined with surgery (Groups B and C). These two groups reported better semen quality than patients who received surgery alone or no treatment. No differences were observed between monolateral and bilateral cryptorchidism patients.

CONCLUSIONS

Early prolonged hormonal therapy is advisable in all patients with cryptorchidism independently from the surgical option of promoting testicular descent to the scrotum. Hormonal therapy provides in our study better chance to obtain adequate sperm quality in adult life.

Urinary Tract Endometriosis: How to Predict and Prevent Recurrence after Primary Surgical Excision

STUDY OBJECTIVE

To investigate the clinical and surgical predictors of urinary tract endometriosis (UTE) relapse.

DESIGN

Retrospective single institutional study.

SETTING

Italian multidisciplinary referral center for endometriosis.

PATIENTS

Consecutive patients affected by UTE and surgically treated between January 2016 and March 2020.

INTERVENTION

Surgical excision for UTE. Uni- and multivariate logistic regression analyses were fitted to evaluate clinical and surgical predictors of recurrence.

MEASUREMENTS AND MAIN RESULTS

A total of 105 female age-reproductive patients were enrolled. Median age was 32 years (interquartile range, 24-37). Ureteral involvement was recorded in 53 patients (50.5%), being unilateral and bilateral in 46 patients (43.8%) and 7 patients (6.7%), respectively. Bladder involvement occurred in 52 patients (49.5%). Open surgical approach was performed in 24 cases (22.9%), whereas 30 patients (28.5%) and 51 patients (48.6%) were treated with laparoscopic and robot-assisted approach, respectively. Overall, 53 patients (50.5%) received adjuvant hormonal therapy. At a median follow-up of 39 months (interquartile range, 22-51), 30 patients (28.6%) experienced disease relapse, with 14 recurrences (13.3%) recorded at the level of the urinary tract. At multivariable analysis, age at first surgery <25 years (odds ratio [OR], 1.23; 95% confidence interval [CI], 1.10-1.84; p = .02) and the presence of a concomitant autoimmune disease (OR, 1.45; 95% CI, 1.24-2.17; p = .02) were found as predictors of deep infiltrating endometriosis recurrence, whereas adjuvant postsurgical therapy showed a protective role (OR, 0.83; 95% CI, 0.53-0.98; p = .01).

CONCLUSIONS

Young age (<25 years) and the presence of autoimmune diseases were significant predictors for the development of disease recurrence, whereas adjuvant hormonal therapy showed a protective role.

Suboptimal use of hormonal therapy among German men with localized high-risk prostate Cancer during 2005 to 2015: analysis of registry data

Background

This study assesses the use of hormonal therapy to treat high-risk localized prostate cancer (HRLPCa) cases diagnosed between 2005 and 2015.

Methods

All N_0-XM₀ with ≥T_3a, or PCa cases with poorly differentiated feature (equivalent to Gleason score ≥ 8), diagnosed between 2005 and 2015 were extracted from German population-based cancer registries. Cases treated by surgery or chemotherapy were excluded. Description of hormonal therapy use by HRLPCa cases’ profile was presented. Relative risk (RR) was computed with a log-link function to identify factors associated with hormonal therapy use among radiotherapy-treated HRLPCa cases.

Results

A total of 5361 HRLPCa cases were analyzed. Only 27.6% (95% confidence interval [CI]: 26.4–28.8%) of the HRLPCa cases received hormonal therapy in combination with radiotherapy. The use of combined hormonal therapy and radiotherapy varied from 19.8% in Saxony to 47.8% in Schleswig-Holstein.

Application of hormonal therapy was higher for the locally advanced cases compared to the poorly differentiated cases (relative risk [RR] = 1.28; 95%CI: 1.19, 1.37). Older patients showed a slightly increased use of hormonal therapy (RR for a 10-year age increase = 1.09; 95%CI: 1.02, 1.16). Compared to PCa cases from the most affluent residential areas, cases from the least affluent (RR = 0.71; 95%CI: 0.55, 0.92) and medium (RR = 0.75; 95%CI: 0.58, 0.96) areas had decreased use of hormonal therapy. The introduction of the German S3-guideline did not make a marked difference in the uptake of both hormonal therapy and radiotherapy (RR = 1.02; 95%CI: 0.95, 1.09).

Conclusion

This study found a low use of hormonal therapy among HRLPCa patients treated without surgery. The introduction of the German S3-guideline for prostate cancer treatment does not seem to have impacted hormonal therapy use.

Emergency Department Evaluation of Abnormal Uterine Bleeding in US Children's Hospitals

STUDY OBJECTIVE

To assess initial evaluation patterns of patients presenting to the Emergency Department (ED) with abnormal uterine bleeding (AUB) including differences by race DESIGN: Retrospective multicenter cohort study from October 2015 through September 2020 SETTING: Forty-seven children's hospitals submitting data to the Pediatric Health Information System PARTICIPANTS: Female patients aged 8-21 with an ED encounter with AUB as the primary diagnosis code INTERVENTIONS AND MAIN OUTCOME MEASURES: Proportion of visits with at least 1 laboratory assessment for the evaluation of anemia, iron deficiency, and/or hemostatic disorders RESULTS: We identified 17,759 unique patients with AUB seen in the ED who met inclusion criteria. Median age was 16.3 years (IQR, 14.1-17.8 years). Most encounters (n = 11,576, 65.2%) included evaluation for anemia, but only 6.8% (n = 1,215) included assessment for iron deficiency and 26.2% (n = 4,654) for hemostatic disorders. Black patients accounted for 34.7% (n = 6,155) of AUB encounters yet constituted only 25% of all ED encounters (n = 198,192). Black patients with AUB were less likely to undergo bleeding disorder evaluation (OR = 0.76; 95% CI, 0.69-0.83) but more likely to receive evaluation for sexually transmitted infections (OR = 1.63; 95% CI, 1.48-1.80) compared with White patients, despite controlling for age and concomitant pain.

CONCLUSIONS

In a national cohort of adolescents presenting to the ED with AUB, evaluations for anemia and hemostatic disorders were infrequently performed, and racial differences existed regarding initial assessment. Further studies are needed to understand the factors underlying racial differences in hematologic testing and the impact of this disparity on health outcomes for females with AUB.

Neonatal bilateral adrenal hemorrhage and adrenal insufficiency accompanied by Subgaleal hematoma: a case report with brief review of literature

Background

Neonatal adrenal hemorrhage (NAH) is an almost infrequent phenomenon (0.2–0.55%). Mechanical compression and alterations of venous pressure during delivery are considered the most probable explanations. Approximately 10% of the cases might have bilateral involvement. Clinical symptoms include abdominal mass, poor feeding, vomiting, prolonged jaundice, and anemia. Subgaleal hemorrhage (SGH) is one of the most clinically remarkable and potentially hazardous postnatal cranial injuries.

Case presentation

An early-term Iranian male neonate who was born through spontaneous vaginal delivery and experienced shoulder dystocia was diagnosed with bilateral NAH leading to adrenal insufficiency requiring glucocorticoid and mineralocorticoid supplementation. The SGH and jaundice were other postnatal complications. Serial monthly abdominal and brain ultrasound revealed complete regression of lesions after 70 days. However, after 16 months, the neonate has been still treated with hydrocortisone and fludrocortisone for the adrenal insufficiency diagnosis. He has a lower limit weight for age; however, developmental milestones have been appropriate for age.

Discussion and conclusion

Adrenal hemorrhage and SGH should be examined and looked for, particularly with proven evidence of difficult delivery and asphyxia in at-risk newborns. Clinical and ultrasound follow-up is mandatory for the assessment of hemorrhage resolution and conservative management. The early detection and treatment of adrenal insufficiency by laboratory examination is strongly recommended in bilateral cases. Furthermore, the early recognition of postnatal SGH to prevent clinical and neurological outcomes seems essential.

Attitudes of Israeli gynecologists towards risk reduction salpingo-oophorectomy at hysterectomy for benign conditions and the use of hormonal therapy

OBJECTIVES

To investigate the perspectives and attitudes of gynecologists towards risk reduction bilateral salpingo-oophorectomy (RRBSO) in average-risk women at the time of hysterectomy procedure for benign indications divided by age groups, and whether they recommend the use of hormonal therapy post oophorectomy.

METHODS

A questionnaire was distributed during staff meetings either by a printed questionnaire or by a link to a total number of 360 gynecologists include seniors and practitioners. Three hundred and one gynecologists participated in a national survey. Participants completed a structured questionnaire including three different scenarios. The subject group included both attending (senior) and second-year and above resident gynecologists, from divergent subspecialties. The demographic information of the survey responders included sex, age, years of experience, working domain, and subspecialty.

RESULTS

There was a 95% consensus rate among Israeli gynecologists, in favor of the ovarian conservation approach among 45-year-old women, elected for hysterectomy due to benign indications. Whereas in 50-year-old perimenopause women, without any evident family history of ovarian cancer, 39% of gynecologists advocated BSO at the time of hysterectomy, for benign indications. As for 46-year-old women, with a first-degree relative diagnosed with ovarian cancer at the age of 65 years old, 70.4% voted for prophylactic BSO. For the second part of the questionnaire regarding the utilization of hormone therapy (HT) after BSO, 66.1% of our responders proclaimed they would always encourage the use of HT in 45-year-old-women, while 52.8% recommended HT in 46-year-old-women with a family history of ovarian cancer and 39.5% for 50-year-old perimenopause women.

CONCLUSION

Our national survey confirms the wide variability in attitudes among gynecologists towards performing RRBSO at hysterectomy for a benign indication in women aged 45-50, with family history being a major factor in the decision.

Endometriosis and Pelvic Pain for the Gastroenterologist

Endometriosis, affecting 5-10% of reproductive-age women, is a common contributor to dysmenorrhea and chronic pelvic pain. Diagnosis requires laparoscopic tissue biopsy, but careful pelvic examination, and/or imaging with either ultrasound or MRI, may identify patients who should receive empiric first-line therapy. The presence of dyschezia, particularly with cyclical exacerbation, should raise suspicion for bowel or rectovaginal septum involvement, and a greater need for surgical management. Treatment of dysmenorrhea includes hormonal suppression of the menstrual cycle, and/or analgesics; more severe cases with strong pain and disability may require earlier surgical intervention to excise disease while preserving fertility desires.

The prognostic significance of serum interferon-gamma (IFN-γ) in hormonally dependent breast cancer

BACKGROUND

Interferon-γ (IFN-γ) is a pleiotropic immunomodulatory cytokine. Because of its contradictory and even dualistic roles in malignancies, its potential as a biomarker remains to be unraveled.

AIM

To evaluate the prognostic significance of serum IFN-γ in hormonally treated breast cancer patients.

MATERIAL AND METHODS

The study included 72 premenopausal breast cancer patients with known clinicopathological characteristics. All patients received adjuvant hormonal therapy based on hormone receptor-positivity. The median follow-up period was 93 months. IFN-γ serum protein levels were determined by quantitative ELISA. Prognostic performance was evaluated by the receiver operating characteristic (ROC), Cox proportional hazards regression and Kaplan-Meier analyses. Classification of patients into IFN-γ^low and IFN-γ^high subgroups was performed by the use of the outcome-oriented cut-off point categorization approach.

RESULTS

The best prognostic performance was achieved by IFN-γ (AUC = 0.24 and p = 0.01 for distant events, AUC = 0.29 and p = 0.01 for local and distant events combined). Age and IFN-γ were prognostically significant in instances of all types of outcomes and IFN-γ was the independent prognostic parameter (Cox regression). There was a significant difference between IFN-γ values of patients without any events and those with distant metastases (Mann-Whitney test, p = 0.007). IFN-γ levels correlated significantly with nodal status and tumor stage (Spearman's rank order, r = -0.283 and r = -0.238, respectively). Distant recurrence incidence was 4% for the IFN-γ^high subgroup and 33% for the IFN-γ^low subgroup (Kaplan-Meier analysis).

CONCLUSIONS

Raised serum IFN-γ levels associate independently with favorable disease outcome in hormonally dependent breast cancer.

The Use of Targeted Agents in the Treatment of Gynecologic Cancers

OPINION STATEMENT

Patients with advanced and recurrent ovarian, uterine, and cervical cancers have limited efficacious treatment options and poor outcomes. The development of agents that target DNA repair mechanisms, angiogenesis, immune checkpoints, and hormone receptor expression provides additional options for these patients. Many available targeted therapies have limited efficacy as single agents, so clinical trials investigating combination therapies as well as continued identification and validation of predictive biomarkers are critical. Many novel small molecule therapies, antibody drug conjugates, and therapeutic vaccines are also in development. This review will focus on recent evidence supporting the use of clinically available targeted therapies for gynecologic cancer.

Sexuality in breast cancer survivors: sexual experiences, emotions, and cognitions in a group of women under hormonal therapy

BACKGROUND

Earlier diagnosis and improved treatments have led to better outcomes in breast cancer, making quality of life a key issue. Sexuality represents a pillar of quality of life, although it is often neglected by both healthcare providers and patients when it comes to cancer. This study aims to explore the differences in sexual functioning, distress, psychopathology, emotions, and cognitions between breast cancer patients under hormonal treatment and controls.

METHODS

Seventy-nine women (age range between 24 and 69 years) in hormonal therapy for breast cancer completed a self-reported protocol. A matched control group of 103 women was randomly extracted from an Italian general population database. Eight self-report questionnaires exploring biopsychosocial factors were administered.

RESULTS

The current study showed an impaired sexuality in breast cancer patients compared to controls. Breast cancer women under hormonal treatment were characterized by diminished or absent sexual activity (chi² = 36.16; p < 0.001), lower level of sexual functioning in all areas except for pain (F_(1,180) = 8.1; p < 0.01), higher sexual (F_(1,180) = 10.08; p < 0.001) and psychological distress (F_(1,180) = 6.23; p < 0.05), higher scores in Difficulties in Identifying Feelings (F_(1,180) = 7.31; p < 0.01) and Externally Oriented Thinking (F_(1,180) = 6.64; p < 0.05), higher level of negative emotions related to sexuality (F_(1,180) = 11.13; p < 0.001), and more rigid cognition towards peculiar aspects of sexuality, such as Failure Disengagement Thoughts (F_(1,180) = 22.01; p < 0.001) and Age related Beliefs (F_(1,180) = 5.7; p < 0.05).

CONCLUSIONS

Health care providers do not usually assess those issues in their routine practice, so that sexuality remains an unmet need with remarkable effects on general health and quality of life.

Low Corticosterone Response to Stress in a Perimenopausal Rat Model Is Associated with the Hypoactivation of PaMP Region of the Paraventricular Nucleus and Can Be Corrected by Exogenous Progesterone Supplementation

INTRODUCTION

The transition to menopause is characterized by mood, behavioral and metabolic changes. However, little is known about the changes in adrenal response to stress.

AIMS

The aim of the study was to evaluate, in an animal model of perimenopause induced by 4-vinylcyclohexene diepoxide (VCD), (1) the endocrine and neuronal stress system activity in response to acute restraint stress and (2) the effect of hormonal therapy in this response.

METHODS

Prepubertal female Wistar rats received daily injections (s.c) of oil or VCD (160 mg/kg) for 15 days. On 56th-66th days after treatment onset, the groups to be stressed received s.c implants containing placebo (PL), 17β-estradiol (E2), progesterone (P4), or E2P4. At 80 ± 5 days after VCD/oil injections, stress was applied for 30 min. Blood samples were collected immediately after and 60 min after the end of stress session from the tail tip followed by transcardial perfusion with PFA 4% for the assessment of c-Fos expression in the medial and posterior parvocellular (PaMP and PaPo) subdivisions of the paraventricular nucleus (PVN) and c-Fos/tyrosine hydroxylase in the locus coeruleus (LC) using immunohistochemistry. Control groups were not stressed nor received hormone therapy.

RESULTS

While basal corticosterone levels were similar between VCD-periestropausal and control rats, the secretion in response to stress in the VCD group was lower. This effect was prevented by P4 therapy. Inversely, basal levels of P4 were lower in VCD-periestropausal rats than in the controls, and no differences were found in response to stress between the groups. As expected, 30-min restraint stress increased c-Fos immunoreactivity in all brain areas studied in both control and VCD-periestropausal rats. However, the c-Fos increase in the PaMP region was attenuated. In all areas examined, there were no significant differences in the number of c-Fos-positive neurons across hormonal therapies.

DISCUSSION/CONCLUSION

This is the first study to demonstrate in a perimenopausal rat model that reproductive aging is accompanied by inadequate secretion of corticosterone in response to acute stress in association with the hypoactivation of the PaMP region of the PVN, while adrenal P4 response is preserved. Moreover, P4 therapy was shown to attenuate the effects of progressive ovarian failure on adrenal functioning during stress.

Phase II Trial of Enzalutamide and Androgen Deprivation Therapy with Salvage Radiation in Men with High-risk Prostate-specific Antigen Recurrent Prostate Cancer: The STREAM Trial

BACKGROUND

Salvage external beam radiotherapy (RT) with androgen deprivation therapy (ADT) improves survival over RT in men with prostate cancer (PC) and rising prostate-specific antigen (PSA) levels after radical prostatectomy (RP).

OBJECTIVE

To investigate the safety and efficacy of enzalutamide concurrent with salvage RT and ADT.

DESIGN, SETTING, AND PARTICIPANTS

This was a three-center prospective phase 2 single-arm trial (NCT02057939) of men with Gleason 7-10 PC and PSA recurrence within 4 yr of RP ranging from 0.2 to 4.0 ng/dl, no prior hormonal therapy, and no radiographic evidence of metastases. We enrolled 38 men; 37 completed therapy and were evaluable with testosterone recovery at 2 yr.

INTERVENTION

Six months of ADT with 160 mg/d enzalutamide and 66 Gy RT to the prostate bed.

OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS

The primary endpoint was improved 2-yr progression-free survival (PFS) over historical controls. Secondary objectives included 3-yr PFS, safety, and patient-reported quality of life (QOL).

RESULTS AND LIMITATIONS

The primary endpoint of 2-yr PFS was 65% (95% confidence interval [CI]: 47, 78) versus 51% (95% CI: 33, 67) in a trial of men with similar eligibility treated with salvage RT and adjuvant docetaxel. The 3-yr PFS was 53%. Eleven (29%) men experienced G3 toxicities, and there were no G4-5 or unexpected toxicities. QOL data suggest modest worsening of bowel, bladder, and hormonal symptoms at 3 mo, with recovery by 24 mo in most men.

CONCLUSIONS

Salvage RT with enzalutamide and ADT following RP for men with PSA recurrent high-risk PC is safe and demonstrates encouraging efficacy, warranting prospective controlled phase 3 trials of ADT with or without potent androgen receptor inhibition in this curative-intent setting.

PATIENT SUMMARY

Addition of 6 mo of oral daily enzalutamide to standard salvage radiation and hormone therapy is safe and may improve prostate cancer remission rates at 2 and 3 yr.

Effect of Estrogen Receptor Expression Level and Hormonal Therapy on Prognosis of Early Breast Cancer

Purpose

Estrogen receptor (ER) expression in breast cancer plays an essential role in carcinogenesis and disease progression. Recently, tumors with low level (1%–10%) of ER expression have been separately defined as ER low positive (ER^low). It is suggested that ER^low tumors might be morphologically and behaviorally different from tumors with high ER expression (ER^high).

Materials and Methods

Retrospective analysis of a prospective cohort database was performed. Patients who underwent curative surgery for early breast cancer and had available medical records were included for analysis. Difference in clinicopathological characteristics, endocrine responsiveness and five-year recurrence-free survival was evaluated between different ER subgroups (ER^high, ER^low, and ER-negative [ER⁻]).

Results

A total of 2,162 breast cancer patients were included in the analysis, Tis and T1 stage. Among them, 1,654 (76.5%) were ER^high, 54 (2.5%) were ER^low, and 454 (21.0%) were ER⁻ patients. ER^low cases were associated with smaller size, higher histologic grade, positive human epidermal growth factor receptor 2, negative progesterone receptor, and higher Ki-67 expression. Recurrence rate was highest in ER⁻ tumors and was inversely proportional to ER expression. Recurrence-free survival was not affected by hormonal therapy in the ER^low group (p=0.418).

Conclusion

ER^low breast cancer showed distinct clinicopathological features. ER^low tumors seemed to have higher recurrence rates compared to ER^high tumors, and they showed no significant benefit from hormonal therapy. Future large scale prospective studies are necessary to validate the treatment options for ER^low breast cancer.

The Effect of an Information Support Program on Self-Efficacy of Prostate Cancer Patients during Hormonal Therapy

OBJECTIVE

This study was conducted to evaluate the effect of an information support program on the self-efficacy (SE) of prostate cancer (PCa) patients receiving hormonal therapy (HT).

METHODS

Based on the information support program constructed in a previous study, a randomized controlled trial was conducted in a cancer hospital in Shanghai, China. One hundred subjects were randomly divided into two groups. The control group was provided routine care and communication, and the experimental group participated in an informational support program. Three months later, the following outcomes were compared between the two groups: information acquisition, disease knowledge mastery, SE, healthy behavior adherence, health-related quality of life (HRQoL), and serum prostate-specific antigen (PSA) levels. t-test and Wilcoxon rank-sum test were used to compare the differences between the two groups, and intention-to-treat analysis was used to increase the reliability of the results.

RESULTS

After the intervention, information acquisition, disease knowledge mastery, and the SE and healthy behavior adherence of the experimental group were significantly increased compared with the control group, whereas the HRQoL and PSA did not significantly differ from that observed in the control group.

CONCLUSIONS

The results showed that information support programs improve information acquisition, disease knowledge mastery, SE, and healthy behavior adherence among PCa patients receiving HT.

Development and Refinement of a Telehealth Intervention for Symptom Management, Distress, and Adherence to Adjuvant Endocrine Therapy after Breast Cancer

Adjuvant endocrine therapy (AET) prevents recurrence after early stage, hormone sensitive breast cancer; however, adherence to AET is suboptimal, and efficacious interventions are severely lacking. Barriers to adherence are well established; however, interventions, thus, far have failed to produce meaningful changes in adherence and have generally not followed guiding principles of psychosocial intervention development. The purpose of this paper is to describe the iterative development, using the National Institutes of Health Stage Model for Behavioral Intervention Development, of an evidence-based, patient-centered, telehealth intervention to enhance adherence, improve symptom management, and reduce distress for patients taking AET after breast cancer, with a focus on (1) a small open pilot study which informed modifications and refinement of the intervention based on quantitative and qualitative patient feedback about feasibility and acceptability and (2) the underlying theoretical and empirical rationale for each component of the finalized intervention. Clinical implications and directions for future research are discussed.

The significance of HOXB7 and IL17RB serum levels in prognosis of hormonally dependent breast cancer: A pilot study

PURPOSE

Improved prognostication of a patient's outcome could allow for personalized treatment decisions in breast cancer. Homeobox B7 (HOXB7) and interleukin 17 receptor B (IL17RB) are proteins reportedly involved in the development of hormonal therapy resistance. Their prognostic value was previously investigated in tumor tissue but recent mass spectrometric detection of HOXB7 and IL17RB proteins in serum has prompted us to perform the first prognostic evaluation of their serum levels.

PATIENTS AND METHODS

The study included 81 premenopausal breast cancer patients that received adjuvant hormonal therapy. The median follow-up period was 61 months. HOXB7 and IL17RB serum protein levels were measured by quantitative sandwich ELISA and prognostically evaluated by Cox proportional hazards regression analysis.

RESULTS

HOXB7 protein was detected in 96.3% and IL17RB in 33.3% of serum samples. Higher levels of serum HOXB7 significantly associated with favorable disease outcome by prognosticating distant (by HR ​= ​0.04; P ​= ​0.001) and local recurrence (by HR ​= ​0.03, P ​= ​0.001). The recurrence rates in the HOXB7^high and HOXB7^low subgroups of patients (cut-off 81.5 ​pg/mL) were 0% and 17%, respectively. Serum IL17RB levels did not significantly associate with either local or distant events. The multivariate analysis highlighted estrogen receptor, histological grade, nodal status and HOXB7 as independent prognostic parameters.

CONCLUSIONS

Our findings validate the previous mass-spectrometry data by showing that HOXB7 and IL17RB cellular proteins are detectable in serum by a standard ELISA assay. Furthermore, we show that HOXB7 serum levels are the relevant prognosticator of response to hormonal therapy.

Intravenous Methylprednisolone Versus Oral Prednisolone for West Syndrome: A Randomized Open-Label Trial

OBJECTIVE

To compare intravenous methylprednisolone (IVMP) with oral prednisolone (OP) for the treatment of West syndrome.

METHODS

In this randomized, open-label trial, children aged 2 to 30 mo presenting with epileptic spasms with hypsarrhythmia or its variants on EEG were randomized to receive either IVMP (30 mg/kg/d for 3 d followed by oral prednisolone taper) or OP (4 mg/kg/d for two weeks followed by taper). The primary outcome measure was spasms cessation on day 14. Secondary outcomes included time to response, electroclinical remission at 2 and 6 wk, and frequency of adverse effects. ( ClinicalTrials.gov Identifier: NCT03876444).

RESULTS

Sixty children were enrolled; 31 in the IVMP and 29 in the OP arm. Proportion of children achieving spasms cessation at day 14 was similar in both groups (54.8% versus 68.9%, p = 0.26). Time to achieve remission was lower in the IVMP group (mean 5.4 ± 0.9 versus 9.5 ± 2.6 d, p < 0.0001). Electroclinical remission at 2 wk was similar in both groups (51.6% versus 44.8%, p = 0.59) but lower at 6 wk in the IVMP group (45.2% versus 75.9%, p < 0.015). Adverse effects like sleep disturbance, irritability and hypertension were more common in IVMP group whereas weight gain was more common in the OP group.

CONCLUSIONS

There was no significant difference in spasms cessation between the groups on day 14 although remission was higher at 6 wk in OP group. Our study suggests that OP was better than IVMP in efficacy and sustained remission with fewer adverse effects.

Complete remission of advanced low-grade endometrial stromal sarcoma after aromatase inhibitor therapy: a case report

Background

Low-grade endometrial stromal sarcoma is a rare neoplastic growth in the uterine cavity, representing less than 1% of uterine tumors. Such tumors usually affect premenopausal and perimenopausal women, with a mean age of 46 years. Treatment generally starts with surgical resection of the tumor, followed by chemotherapy, radiotherapy, or hormonal therapy.

Case presentation

In the current report, we again present a case of low-grade endometrial stromal sarcoma in a 51-year-old Mediterranean woman presenting with abdominopelvic pain. Computed tomography scan revealed a primary uterine tumor measuring 17 × 9 × 9 cm metastasizing to the lungs, bladder, and ureteral orifice, along with lymphovascular involvement. The patient underwent total abdominal hysterectomy, omentectomy, and lymph node dissection. Estrogen deprivation was accomplished by bilateral salpingo-oophorectomy. Lifelong hormonal therapy consisting of letrozole 2.5 mg per day was prescribed, which demonstrated remarkable efficacy, resulting in a partial remission of lung metastasis within 8 months after surgery. Full remission was observed after 18 months of hormonal therapy, with no recurrence. Another scan was performed after 2.5 years, revealing complete remission with no recurrence.

Conclusion

We again report a case of complete remission of low-grade endometrial stromal sarcoma after surgical removal of the tumor along with first-line hormonal therapy without the use of chemotherapy or radiotherapy, emphasizing the role of hormonal therapy in the treatment of such tumors.

Mapping evidence on the effects of gender-affirming hormone therapy on the hard and soft tissues of the craniofacial complex in transgender people: a protocol for a scoping review

BACKGROUND

Gender-affirming hormone (GAH) therapy aims to support the transition of transgender people to their gender identity. GAHs can induce changes in their secondary sex characteristics such as the development of breasts in transgender females and increased muscle mass in transgender males. The face and its surrounding tissues also have an important role in gender confirmation. The aim of this scoping review is to systematically map the available evidence in order to provide an overview of the effects of GAH therapy on the hard and soft tissues of the craniofacial complex in transgender people.

METHODS/DESIGN

The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA) extension for Scoping Reviews was consulted for reporting this protocol. The methods were based on the Arksey and O'Malley's framework and the Reviewer's Manual of the Joanna Briggs Institute for conducting scoping reviews. Ten transgender people were involved in the development of the primary research question through short interviews. The eligibility criteria were defined for transgender people undergoing GAH therapy and for quantitative and qualitative outcomes on the hard and soft tissues of the craniofacial complex. Eligible sources of evidence include observational, experimental, qualitative, and mixed method studies. No exclusion criteria will be applied for the language of publication and the setting. To identify eligible sources of evidence, we will conduct searches from inception onwards in PubMed, Embase.com , the Cochrane Library, Web of Science Core Collection, Scopus, CINAHL, LIVIVO, and various grey literature sources such as Google Scholar. Two reviewers will independently select eligible studies in these information sources and will subsequently conduct data extraction. The same operators will chart, categorize, and summarize the extracted data. A narrative summary of findings will be conducted. Frequency counts of quantitative and qualitative data on items such as concepts, populations, interventions, and other characteristics of the eligible sources will be given. Where possible, these items will be mapped descriptively.

DISCUSSION

We chose the scoping review over the systematic review approach, because the research questions are broad-spectrum and the literature is expected to be widely scattered. No systematic review has previously assessed this topic. Identifying knowledge gaps in this area and summarizing and disseminating research findings are important for a wide spectrum of stakeholders, in particular, for transgender people who want to undergo additional interventions such as plastic or orthognathic surgery or orthodontics.

The prognostic value of cyclin D1 in breast cancer patients treated with hormonal therapy: A pilot study

THE AIM

of the study was to determine the clinical relevance of cyclin D1 (cD1) and its association with clinicopathological parameters in breast cancer patients treated with hormonal therapy.

MATERIAL AND METHODS

The study included 96 primary breast cancer patients with known clinicopathological parameters. In adjuvant setting, 44 patients were tamoxifen-treated and 52 were treated with ovarian irradiation/ablation. The cD1 status (gene amplified/nonamplified) was determined on formalin-fixed paraffin-embedded tumor tissue sections by chromogenic in situ hybridization. Associations between parameters were analyzed by Chi-square and Spearman's rank order correlation tests. Cox proportional hazards regression test was performed. Survival curves for relapse-free survival were constructed according to the Kaplan-Meier method.

RESULTS

There were no significant associations between cyclin D1 and clinicopathological parameters in either patient group. Amplified cyclin D1 associated significantly with the actual relapse incidence in the ovarian ablation patient group (p = 0.01, HR = 3.1), but not in the tamoxifen-treated patient group. Estrogen receptor and cyclin D1 have proven to be independent parameters of poor outcome in the ovarian ablation patient group (p = 0.03, HR = 2.9; and p = 0.009, HR = 2.5; respectively).

CONCLUSIONS

Cyclin D1 might be a candidate biomarker of poor outcome in breast cancer patients treated with ovarian ablation, suggesting its possible involvement in acquirement of hormonal resistance. The role of cyclin D1 as potential parameter of response to tamoxifen was not as pronounced.

Assessment of Total, PTEN-, and AR-V7+ Circulating Tumor Cell Count by Flow Cytometry in Patients with Metastatic Castration-Resistant Prostate Cancer Receiving Enzalutamide

INTRODUCTION

Metastatic castration-resistant prostate cancer (mCRPC) is a deadly disease. Enzalutamide is an oral second-generation anti-androgen that is active in mCRPC. Circulating tumor cells (CTC) count correlates with overall survival (OS) in mCRPC, whereas detection of the androgen-receptor splice variant 7 (AR-V7) in CTC predicts poor response to oral second-generation anti-androgens. Also, loss of PTEN (phosphatase and tensin homolog) in CTC is a biomarker of poor prognosis in mCRPC.

PATIENTS AND METHODS

In this translational study, we employed flow cytometry to assess total, PTEN^-, and AR-V7⁺ CTC count per 7.5 mL of whole blood in a prospective cohort of patients with mCRPC receiving enzalutamide.

RESULTS

CTCs were assessed in a total of 45 men with mCRPC at baseline and at 12 weeks. Overall, CTC, PTEN^- CTC, and AR-V7⁺ CTC detection rate was high, at baseline, with 84.4%, 71.1%, and 51.1% of samples showing at least 1 cell/7.5-mL blood, respectively, and after 3 months, with 93.3%, 64.4%, and 77.7% of samples showing at least 1 cell/7.5-mL blood, respectively. Median radiographic progression-free survival (rPFS) and OS were 6 (95% confidence interval [CI], 5.6-9) and 14.3 (95% CI, 12.8-20.3) months, respectively. Median (interquartile range) total CTC count at baseline was 5 (3; 8), whereas median (interquartile range) PTEN^- CTC count was 2 (0; 4) and median (interquartile range) AR-V7⁺ CTC count was 1 (0; 3). At baseline, ≥ 5 versus < 5 total CTC count was associated with worse rPFS (hazard ratio [HR], 2.35; 95% CI, 1.14-4.84; P= .021) and OS (HR, 3.08; 95% CI, 1.45-6.54; P = .003), whereas ≥ 2 versus < 2 PTEN^- CTC count was associated with worse rPFS (HR, 3.96; 95% CI, 1.8-8.72; P= .001) and OS (HR, 2.36; 95% CI, 1.12-5; P= .025). Finally, ≥ 1 versus < 1 AR-V7⁺ CTC count was also associated with worse rPFS (HR, 5.05; 95% CI, 2.4-10.64; P< .001) and OS (HR, 2.25; 95% CI, 1.1-4.58; P= .026).

CONCLUSIONS

Despite multiple limitations, including the small sample size, our preliminary study suggests that assessment of CTC via flow cytometry may provide potentially useful prognostic and predictive information in advanced prostate cancer. Further studies are warranted. Micro-Abstract: In this study, men with metastatic castration-resistant prostate cancer, scheduled to start enzalutamide, were assessed for circulating tumor cell count and molecular characterization (total, PTEN^-, and AR-V7⁺ circulating tumor cell count) by the use of flow cytometry. We found that flow cytometry could be used to enumerate circulating tumor cells, but also to assess molecular biomarkers on their surface.

Stroke in Male-to-Female Transgenders: A Systematic Review and Meta-Analysis

BACKGROUND

The effect of hormonal therapy has been extensively studied in women. However, similar data on male-to-female (MTF) transgenders, another important population that receives hormonal therapy is lacking. Existing studies in MTF transgenders are skewed toward mental health and health-harming behaviors while few have focused on chronic health conditions. Our study aims to review the existing data on stroke in MTF transgenders and perform a quantitative analysis on the frequency of this condition in this special population.

METHODS

PubMed, Cochrane, Scopus, Embase, ClinicalTrials.gov, and Web of Science were systematically searched for studies that reported data on the occurrence of cerebrovascular diseases in MTF transgenders. We reported the hormonal regimens, clinical characteristics, and outcomes of stroke in MTF transgenders. A meta-analysis of proportions was performed by the random-effects model to compute for the frequency of cerebrovascular events in MTF transgenders.

RESULTS

Fourteen studies were included in the qualitative analysis while five studies were included in the quantitative analysis. A total of 109 MTF transgenders (Mean 14; range 1-53) suffered a cerebrovascular event. Random-effect modeling analysis showed an overall estimated frequency of 2% for cerebrovascular events in transgenders with a moderate degree of heterogeneity (I2 = 62%).

CONCLUSION

Hormonal therapy in MTF transgenders may confer cardiovascular risks in this population. However, more population-based studies that include clinical characteristics and outcomes of chronic health diseases in MTF transgenders are warranted. Such studies may be crucial in directing future guidelines on the health care and management of MTF transgenders.

Effect of adjunctive hormonal therapy on testicular descent and spermatogenic function among children with cryptorchidism: a systematic review and meta-analysis

OBJECTIVES

To systematically evaluate the effect of adjunctive hormonal therapy on testicular descent and spermatogenic function among children with cryptorchidism.

METHODS

A comprehensive literature search of electronic databases up to February 21, 2019 was performed. Continuous data of fertility indices were evaluated using weighted mean difference (WMD) with 95% confidence interval (CI), while nominal data of fertility indices and the complete descent rates were analyzed by risk ratio (RR) with 95% CI. A fixed effect or random effect model was used.

RESULTS

A total of 27 previous studies were included for the current analysis. Hormonal therapy increased complete testicular descent rate, reaching statistical significance (RR = 3.74; 95% CI, 2.78-5.04; P < 0.001). The success rate was 22.43%. A similar result was found in subgroup analysis of hormonal category and effect on unilateral or bilateral cryptorchidism. Studies reporting primary outcome as continuous data showed that cryptorchid males have significantly increased germ cell numbers per tubule (WMD = 0.10; 95% CI, 0.01-0.20, P = 0.032) after hormonal therapy. The nominal data of pooled studies showed no significant difference (RR = 1.62; 95% CI, 0.65-4.00, P = 0.298). In addition, a significant result was noted in the luteinizing hormone-releasing hormone (LHRH) therapy group but not in those undergoing human chorionic gonadotropin (hCG) treatment.

CONCLUSIONS

Our findings have demonstrated that hormonal therapy can effectively increase the success rate of complete testicular descent, while some boys may benefit as regards improvement of the fertility index.

Live births and maintenance with levonorgestrel IUD improve disease-free survival after fertility-sparing treatment of atypical hyperplasia and early endometrial cancer

OBJECTIVE

Our objectives were to (1) compare different regimens of hormonal therapy (HT) in young women with atypical endometrial hyperplasia (AEH) and early endometrial cancer (EC), (2) assess reproductive and oncologic outcomes and (3) explore possible predictors of complete response (CR) and disease free survival (DFS).

METHODS

Reproductive age women with AEH and Grade 1-2 endometrioid EC with no or minimal myometrial invasion on MRI treated with different regimens of HT were prospectively analyzed. Treatment protocols included levonorgestrel intrauterine device (LNG IUD), gonadotropin-releasing hormone agonist (aGnRH) or high-dose oral medroxyprogesteron acetate (MPA) separately and in combinations.

RESULTS

Total of 418 patients with AEH (n = 228) and EC (n = 190) aged 19-46 years received HT. Overall CR rate was 96% in AEH and 88% in EC patients (р < 0.001). None of the regimens used in AEH (LNG IUD + 2 D&C vs. LNG IUD + aGnRH vs. LNG IUD + 3 D&C) was found inferior to the others (CR of 98%, 95%, 100%, respectively, p > 0.05) except for MPA alone (CR 87%, р = 0.009). Out of four HT regimens used in EC LNG IUD + aGnRH+3 D&C was superior to all others (CR 96%, р = 0.026) where 2 D&Cs were performed or oral MPA was prescribed. The median follow-up for 339 patients was 33 months (range: 3-136), 68% of patients (n = 232) attempted conception, 38% (n = 89) of them used ART. The birth rate was 42% (n = 97). The rate of recurrence was 26% (50/196) in AEH group and 36% (51/143) in EC group (p = 0.05). Birth after treatment (HR = 0.24) or LNG IUD maintenance (HR = 0.18) were associated with superior DFS (p < 0.001 for both). ART use did not influence DFS.

CONCLUSION

Hormonal therapy of AEH and early EC with LNG IUD is superior to MPA-containing regimens, however still carries high risk of recurrence. Post-treatment pregnancy rates are satisfactory and can be further improved by broader ART use which was proven safe. Initial diagnosis of AEH, post-treatment child birth and LNG IUD maintenance were associated with decreased rates of recurrence.
