    性健康是子宫内膜异位症女性的主要关注点,然而,只有少数对照研究用经过验证的仪器检查了这一点。激素治疗对子宫内膜异位症性功能的影响也是一个被低估的话题。这项研究的目的是通过一种特定的工具来调查子宫内膜异位症患者的性功能,以更好地评估他们的性功能(包括不同的领域)。以及激素治疗或手术对这些参数的影响。
    观测,横截面,多中心研究是在一组(n=194)性活跃的人中进行的,25-45岁的女性,手术或超声诊断为子宫内膜异位症,转诊到Careggi大学医院或NegrardiValpolicella的子宫内膜异位症中心。通过女性性功能指数(FSFI)评估性功能,评估欲望的领域,唤醒,润滑,性高潮,满意和痛苦。根据子宫内膜异位症患者接受的治疗,将FSFI评分与对照组(n=58)进行比较。
    卵巢子宫内膜异位症有50例(25.8%),65例(33.5%)和79例(40.7%)均为深部浸润型子宫内膜异位症。102例(52.6%)同时存在子宫腺肌病。子宫内膜异位症女性FSFI平均总评分为18.3[4.2-25.8](<26.55),表明所有患者的女性性功能障碍(FSD)。在多变量分析中,在调整了混杂因素(BMI和激素治疗)后,在所有FSFI中,子宫内膜异位症女性的评分均显著低于对照组(p<0.001).激素治疗下的子宫内膜异位症患者(n=124;64%),无论类型,在所有FSFI分量表和总分中得分明显较低,即使在调整了混杂因素年龄之后,BMI和手术史。
    子宫内膜异位症患者有FSD的风险,不仅包括性交困难,而是性功能的所有领域。激素治疗不会导致性症状的改善。
    UNASSIGNED: Sexual health is a major concern in women with endometriosis, however only a few controlled studies have examined this with validated instruments. The effect of hormonal treatments on sexual function in endometriosis is also an underrated topic. The aim of this study was to investigate sexual function of patients with endometriosis by a specific tool to better evaluate their sexual function (including different domains), and the influence of hormonal treatment or surgery on these parameters.
    UNASSIGNED: An observational, cross-sectional, multicentre study was conducted in a group (n=194) of sexually active, women aged 25-45 years old, with surgical or ultrasonographic diagnosis of endometriosis, referred to the Endometriosis Center of Careggi University Hospital or Negrar di Valpolicella. Sexual function was assessed by administering the Female Sexual Function Index (FSFI), which assesses the domains of desire, arousal, lubrication, orgasm, satisfaction and pain. FSFI scores were compared to those of a control group (n=58) and according to the treatment received by patients with endometriosis.
    UNASSIGNED: Ovarian endometriosis was present in 50 patients (25.8%), deep infiltrating endometriosis in 65 patients (33.5%) and both in 79 patients (40.7%). Adenomyosis coexisted in 102 patients (52.6%). Women with endometriosis reported a mean total FSFI score of 18.3 [4.2-25.8] (< 26.55), indicating female sexual dysfunction (FSD) in all patients. At multivariate analysis, after adjusting for confounders (BMI and hormonal therapy), women with endometriosis presented significantly lower scores than controls in all the FSFI (p<0.001). Patients with endometriosis under hormonal treatments (n=124; 64%), regardless of the type, had significantly lower scores in all FSFI subscales and total score, even after adjusting for confounders-age, BMI and history of surgery.
    UNASSIGNED: Patients with endometriosis are at risk for FSD, encompassing not only dyspareunia, but all domains of sexual function. Hormonal treatments do not result in improvement in sexual symptoms.

    前列腺癌(PC)通常是激素依赖性肿瘤。雄激素剥夺疗法(80多年来一直是转移性疾病的标准护理。随后的研究强调了ADT的功效,即使在早期疾病中,例如在局部疾病中或在生化复发(BCR)的情况下。对PC生物学和ADT抗性机制的认识提高导致了新一代雄激素受体途径抑制剂(ARPI)的开发。最初仅用于对ADT产生抗药性的患者,随后,ARPI在用于转移性激素初治疾病的患者中时显示出有效的效果,并且近年来,在局部疾病和BCR的情况下也对其有效性进行了评估。这篇综述的目的是描述在PC的不同阶段干扰雄激素受体的试剂的当前作用,并指出未来的观点。
    Prostate cancer (PC) is generally a hormone-dependent tumor. Androgen deprivation therapy ( has been the standard of care in metastatic disease for more than 80 years. Subsequent studies have highlighted the efficacy of ADT even in earlier disease settings such as in localized disease or in the case of biochemical recurrence (BCR). Improved knowledge of PC biology and ADT resistance mechanisms have led to the development of novel generation androgen receptor pathway inhibitors (ARPI). Initially used only in patients who became resistant to ADT, ARPI have subsequently shown to be effective when used in patients with metastatic hormone-naive disease and in recent years their effectiveness has also been evaluated in localized disease and in case of BCR. The objective of this review is to describe the current role of agents interfering with the androgen receptor in different stages of PC and to point out future perspectives.

    最近的研究利用进化机制来阻止耐药人群的出现。在本文中,我们开发了一个结合激素治疗的数学模型,免疫疗法,以及三种细胞类型之间的相互作用:药物敏感的癌细胞,耐药癌细胞和免疫效应细胞。进行了动态分析,考察均衡的存在性和稳定性,从而确认模型的可解释性。使用可用的前列腺癌数据和文献校准模型参数。通过分叉分析不同免疫效应细胞募集反应下的药物敏感性,我们发现耐药癌细胞在弱募集反应下生长迅速,在强烈的招聘反应下保持在较低水平,两者都可能发生在适度的招募反应下。为了量化敏感和抗性细胞的竞争力,我们分别介绍了综合措施R1和R2,这决定了竞争的结果。此外,我们引入定量指标CIE1和CIE2作为对敏感和耐药癌细胞免疫效应的综合指标,分别。这两个指标决定了相应的癌细胞能否维持在较低水平。我们的工作表明,免疫系统是影响耐药性演变的重要因素,并为如何增强免疫反应以控制耐药性提供了见解。
    Recent studies have utilized evolutionary mechanisms to impede the emergence of drug-resistant populations. In this paper, we develop a mathematical model that integrates hormonal treatment, immunotherapy, and the interactions among three cell types: drug-sensitive cancer cells, drug-resistant cancer cells and immune effector cells. Dynamical analysis is performed, examining the existence and stability of equilibria, thereby confirming the model\'s interpretability. Model parameters are calibrated using available prostate cancer data and literature. Through bifurcation analysis for drug sensitivity under different immune effector cells recruitment responses, we find that resistant cancer cells grow rapidly under weak recruitment response, maintain at a low level under strong recruitment response, and both may occur under moderate recruitment response. To quantify the competitiveness of sensitive and resistant cells, we introduce the comprehensive measures R1 and R2, respectively, which determine the outcome of competition. Additionally, we introduce the quantitative indicators CIE1 and CIE2 as comprehensive measures of the immune effects on sensitive and resistant cancer cells, respectively. These two indicators determine whether the corresponding cancer cells can maintain at a low level. Our work shows that the immune system is an important factor affecting the evolution of drug resistance and provides insights into how to enhance immune response to control resistance.

    低级别浆液性卵巢癌(LGSOC)是浆液性卵巢癌的一种非常罕见的组织学亚型,约占所有上皮性卵巢癌病例的2%。与高级别浆液性卵巢癌(HGSOC)相比,LGSOC具有更好的预后,但对化疗的反应率较低。本研究是对2003年1月至2019年12月在单一机构中诊断和治疗的所有经组织学证实的LGSOC患者的医疗记录的回顾性回顾。共有23例诊断为LGSOC并在费萨尔国王专科医院和研究中心(利雅得,沙特阿拉伯)已确定。诊断时的中位年龄为45.5岁(范围,26-66岁),中位体重指数为26.1(范围,18-43).共有21例患者(91.3%)有从头LGSOC,而只有2例患者(8.7%)的LGSOC从浆液性交界性卵巢肿瘤转化并复发.共有8例(34.8%)被诊断为国际妇产科联合会IV期,而3(13.0%),3(13.0%)和9(39.1%)被诊断为I期,II和III,分别。此外,10(43.5%),5(21.7%),3例(13.0%)患者完全缓解,一线治疗后疾病稳定和部分反应状态,分别。中位随访时间为34个月[95%置信区间(CI),25.32-42.69],中位无进展生存期(PFS)时间为75.2个月(95%CI,17.35~133.05),未达到中位总生存期(OS)时间.总之,与文献数据相比,LGSOC表现出比HGSOC更好的PFS和OS时间,并且有全身治疗(化疗或激素治疗)的选择。最佳的细胞还原显示数值更高,但不重要,PFS和OS时间与次优剔除相比;然而,最佳的全身化疗或激素治疗仍存在争议.
    Low-grade serous ovarian cancer (LGSOC) is a very rare histological subtype of serous ovarian cancer, representing ~2% of all epithelial ovarian cancer cases. LGSOC has a better prognosis but a lower response rate to chemotherapy in comparison to high-grade serous ovarian carcinoma (HGSOC). The present study is a retrospective review of the medical records of all patients with histologically proven LGSOC diagnosed and treated in a single institute between January 2003 and December 2019. A total of 23 patients diagnosed with LGSOC and treated at King Faisal Specialist Hospital and Research Center (Riyadh, Saudi Arabia) were identified. The median age at diagnosis was 45.5 years (range, 26-66 years) and the median body mass index was 26.1 (range, 18-43). A total of 21 patients (91.3%) had de novo LGSOC, whereas only 2 patients (8.7%) had LGSOC that had transformed from serous borderline ovarian tumors and recurred. A total of 8 patients (34.8%) were diagnosed with International Federation of Gynecology and Obstetrics stage IV, whereas 3 (13.0%), 3 (13.0%) and 9 (39.1%) were diagnosed with stages I, II and III, respectively. In addition, 10 (43.5%), 5 (21.7%), and 3 (13.0%) patients had complete response, stable disease and partial response statuses after first-line therapy, respectively. At a median follow-up time of 34 months [95% confidence interval (CI), 25.32-42.69], the median progression-free survival (PFS) time was 75.2 months (95% CI, 17.35-133.05) and the median overall survival (OS) time was not reached. In conclusion, LGSOC exhibited better PFS and OS times than HGSOC as compared with data from the literature, and there is the option for systemic treatment (chemotherapy or hormonal therapy). Optimal cytoreduction showed numerically higher, but non-significant, PFS and OS times compared with suboptimal debulking; however, the optimal systemic chemotherapy or hormonal treatment remains controversial.

    目的:描述经活检证实的子宫内膜异位症的青少年和年轻成人患者子宫内膜异位症激素治疗的当代趋势。
    方法:回顾性图表回顾了2011年1月至2020年9月在三级医院系统接受腹腔镜检查的年龄在14-25岁的女性盆腔疼痛并经活检证实的子宫内膜异位症。最终样本包括91例活检证实的子宫内膜异位症患者。
    结果:联合口服避孕药(COCs)是最常见的初始治疗(64%的患者)。与COC(19.9±3.3岁)和左炔诺孕酮宫内节育器(LNG-IUD)(21.9±1.7岁)相比,向年轻患者(年龄15.9±2.7岁)提供了仅含孕激素的制剂(低剂量和高剂量醋酸炔诺酮)。目前的治疗方法差异很大,包括COCs(32%),液化天然气宫内节育器(18%),口服孕激素(低剂量和高剂量的炔诺酮,甲羟孕酮)(14%),elagolix(9%),和亮丙瑞林(8%)。LNG-IUD的口服辅助治疗很常见:通常使用低剂量或高剂量的炔诺酮(37%的LNG-IUD患者),但也包括黄体酮,COCs,还有Elagolix.
    结论:口服孕激素,液化天然气宫内节育器,COCs是初始治疗的主体。随后的治疗差异很大,包括COCs,液化天然气宫内节育器,口服孕激素,elagolix,亮丙瑞林,以及这些试剂的组合。我们观察到大多数年轻女性在治疗之间切换,建议在当前可用的多种选择中,通常使用个性化方法来确定治疗计划。这项研究有助于确定青春期女性子宫内膜异位症的治疗方案。
    OBJECTIVE: To characterise contemporary trends in the hormonal management of endometriosis in adolescent and young adult patients with biopsy-proven endometriosis.
    METHODS: Retrospective chart review of women aged 14-25 years who underwent laparoscopy for pelvic pain with biopsy-proven endometriosis between January 2011 and September 2020 at an academic tertiary hospital system. The final sample included 91 patients with biopsy-confirmed endometriosis.
    RESULTS: Combined oral contraceptives (COCs) were the most common initial treatment (64% of patients). Progestin-only formulations (low- and high-dose norethindrone acetate) were offered to younger patients (age 15.9 ± 2.7 years) than those offered COCs (19.9 ± 3.3 years) and levonorgestrel intrauterine devices (LNG-IUDs) (21.9 ± 1.7 years). Current treatments varied widely and included COCs (32%), LNG-IUDs (18%), oral progestins (low- and high-dose norethindrone, medroxyprogesterone) (14%), elagolix (9%), and leuprolide (8%). Oral adjuncts to LNG-IUD were common: usually low- or high-dose norethindrone (37% of patients with an LNG-IUD), but also included progesterone, COCs, and elagolix.
    CONCLUSIONS: Oral progestins, LNG-IUDs, and COCs were the mainstay of initial treatment. Subsequent treatments varied widely and included COCs, LNG-IUDs, oral progestins, elagolix, leuprolide, and combinations of these agents. We observed that most young women switched between therapies, suggesting that a personalised approach is often used to determine treatment plans among the wide range of options currently available. This study helps define the spectrum of treatment regimens for endometriosis in adolescent females.

    目的:双侧蝶眶脑膜瘤(bSOM)是脑膜瘤中的一种罕见实体。这些肿瘤是良性的,主要影响女性。它们占蝶眶脑膜瘤(SOM)的4%,在文献中描述甚少。本研究旨在描述其特点,危险因素,进化,
    方法:20例bSOM患者被纳入一项多中心描述性研究,包括15个神经外科。
    结果:在这项研究中,作者发现bSOM只影响女性,平均年龄50岁.大约65%的患者接受孕激素治疗。该系列的平均随访时间为55个月。临床上,视觉症状占优势:20例患者中有17例存在眼球突出(85%;7例单侧,10双边),20例患者中有11例视力下降(55%;6例患者为6/10至9/10,3/10至5/101例患者,4例患者中<3/10)。与单方面的SOM相反,作者认为颅内高压是bSOM的常见表现(25%),全切手术是治疗的金标准.复发仅发生在36%至60%的患者的次全切除术后,手术后的中位时间为50至54个月。75%的病例术后观察到视力改善或稳定性。11例中有10例(91%)的孕激素受体表达水平为70%至100%。
    结论:双侧SOM通常见于女性患者,与激素替代疗法密切相关。就复发和改善视力而言,早期手术治疗和全切除是最有效的治疗方法。鉴于bSOM的缓慢进展性质及其复发时间,可能长达十年,患者的长期随访至关重要。
    OBJECTIVE: Bilateral spheno-orbital meningiomas (bSOMs) are a rare entity among meningiomas. These tumors are benign and predominantly affect women. They represent 4% of spheno-orbital meningiomas (SOMs) and are poorly described in the literature. This study aimed to describe the characteristics, risk factors, evolution, and management of bSOMs.
    METHODS: Twenty patients with bSOMs were enrolled in a multicentric descriptive study including 15 neurosurgical departments.
    RESULTS: In this study, the authors found that bSOMs affected exclusively women, with a mean age of 50 years. Approximately 65% of patients were on progestin therapy. The mean follow-up in this series was 55 months. Clinically, visual symptoms were predominant: proptosis was present in 17 of 20 patients (85%; 7 unilateral, 10 bilateral), and a decrease in visual acuity was observed in 11 of 20 patients (55%; 6/10 to 9/10 in 6 patients, 3/10 to 5/10 in 1 patient, and < 3/10 in 4 patients). Contrary to unilateral SOMs, the authors identified that intracranial hypertension was a common presentation (25%) of bSOMs. Surgical management with gross-total resection was the gold standard treatment. Recurrences only occurred following subtotal resection in 36% to 60% of patients, with a median time of 50 to 54 months after surgery. Visual improvement or stability was observed in 75% of cases postoperatively. Progesterone receptor expression levels were 70% to 100% in 10 of 11 (91%) cases.
    CONCLUSIONS: Bilateral SOMs are usually found in female patients and are strongly associated with hormone replacement therapy. Early surgical management with gross-total resection is the most effective treatment in terms of recurrence and improves visual acuity. Given the slow progressive nature of bSOMs and their time to recurrence, which can be up to 10 years, long-term follow-up of patients is essential.

    目的:这篇综述的目的是讨论绝经与夜尿症之间的联系,并概述患病率的增加,危险因素,致病因素,围绝经期妇女夜尿症的治疗需求和选择。
    方法:本文是基于各种关键意见领袖的专业知识和共识的叙述性回顾,结合广泛的文献综述。该文献检索包括对PubMed数据库和WebofScience上的潜在出版物的全面分析,并于2022年11月至2022年12月进行。使用以下关键词“夜尿症”和“更年期”或“夜间频率和更年期”。\"此外,关键词包括“发病率”,“\”患病率,\"\"失眠,“\”雌激素疗法,代谢综合征,“”和“潮热”与上述关键词结合使用。最后,对所获得的参考文献列表进行了筛选,以获得其他相关文献.
    结果:围绝经期可能是诱发夜尿症的触发因素。通常,肥胖,体重指数(BMI),腰围是围绝经期夜尿症的危险因素。据推测,围绝经期夜尿症的发展是多因素的,膀胱之间的相互作用,睡眠,以及更年期后雌激素耗尽导致的肾脏问题。首先,泌尿生殖区域雌激素受体刺激受损导致阴道萎缩和膀胱容量降低。此外,绝经与膀胱过度活动症的发病率增加有关.第二,雌激素缺乏可通过抗利尿激素分泌和肾素-血管紧张素-醛固酮系统激活的昼夜节律减弱,引起盐和水利尿。此外,睡眠障碍的发病率增加,包括血管舒缩症状和阻塞性睡眠呼吸暂停症状,被观察到。口腔干燥和随之而来的更高的液体摄入量是围绝经期常见的症状。较高的胰岛素抵抗和较高的心血管疾病风险可能会引起夜尿症。考虑到夜尿症对一般健康和生活质量的影响,讨厌的夜尿症应该治疗。最初,应建议进行行为治疗。如果这些修改不充分,应提出具体的处理方法。发现全身性激素替代对夜尿症有有益作用,不影响夜间多尿患者的钠和水清除率。据推测,激素治疗引起的夜尿症的改善是由于睡眠障碍的改善。
    OBJECTIVE: The aim of this review is to discuss the link between menopause and nocturia and to give an overview of the increasing prevalence, risk factors, causative factors, treatment needs and options for nocturia in peri-menopausal women.
    METHODS: This opinion article is a narrative review based on the expertise and consensus of a variety of key opinion leaders, in combination with an extensive literature review. This literature search included a thorough analysis of potential publications on both the PubMed Database and the Web of Science and was conducted between November 2022 and December 2022. The following key words were used \"nocturia\" and \"menopause\" or \"nocturnal frequency and menopause.\" Moreover, key words including \"incidence,\" \"prevalence,\" \"insomnia,\" \"estrogen therapy,\" \"metabolic syndrome,\" and \"hot flushes\" were used in combination with the aforementioned key words. Last, the reference lists of articles obtained were screened for other relevant literature.
    RESULTS: The perimenopause can be a trigger for inducing nocturia. Typically, obesity, body mass index (BMI), and waist circumference are risk factors for developing peri-menopausal nocturia. Presumably the development of peri-menopausal nocturia is multifactorial, with interplay among bladder, sleep, and kidney problems due to estrogen depletion after the menopause. First, impaired stimulation of estrogen receptors in the urogenital region leads to vaginal atrophy and reduced bladder capacity. Moreover, menopause is associated with an increased incidence of overactive bladder syndrome. Second, estrogen deficiency can induce salt and water diuresis through blunted circadian rhythms for the secretion of antidiuretic hormone and the activation of the renin-angiotensin-aldosterone system. Additionally, an increased incidence of sleep disorders, including vasomotor symptoms and obstructive sleep apnea signs, is observed. Oral dryness and a consequent higher fluid intake are common peri-menopausal symptoms. Higher insulin resistance and a higher risk of cardiovascular diseases may provoke nocturia. Given the impact of nocturia on general health and quality of life, bothersome nocturia should be treated. Initially, behavioral therapy should be advised. If these modifications are inadequate, specific treatment should be proposed. Systemic hormone replacement is found to have a beneficial effect on nocturia, without influencing sodium and water clearance in patients with nocturnal polyuria. It is presumed that the improvement in nocturia from hormonal treatment is due to an improvement in sleep disorders.

    背景:雄激素剥夺疗法(ADT)是晚期前列腺癌(PCa)的有效治疗方法。多项研究强调了这种疗法对心理健康造成的严重后果,尤其是抑郁症。我们旨在回顾男性PCa患者ADT的发生率及其与抑郁风险之间的关系。
    方法:我们系统地搜索了多个数据库,包括MEDLINE,Scopus至2023年8月,用于比较ADT与对照治疗PCa的研究报告抑郁症作为结果。使用随机效应模型进行Meta分析,结果以比值比(ORs)和95%置信区间(CI)表示。使用JoannaBriggs研究所关键评估清单对纳入的研究进行质量评估。
    结果:共38项研究(17项回顾性研究,16项前瞻性研究,两项横断面研究和两项随机试验),有360,650名受试者符合纳入标准,并被纳入本荟萃分析.ADT患者中抑郁症的估计合并发生率为209.5(95%CI=122.3;312.2)/1000患者。ADT治疗与抑郁症之间存在统计学上的显著关系(OR=1.46,95%CI=1.28,1.67;p=0,I2=86.4%)。不同亚组的结果保持一致。漏斗图和Eggers检验未发现发表偏倚风险(p>0.05)。
    结论:接受ADT的男性患抑郁症的风险更高。有必要进一步研究评估ADT男性抑郁症的最佳治疗方法。
    BACKGROUND: Androgen deprivation therapy (ADT) is an effective treatment for advanced prostate cancer (PCa). Multiple studies have highlighted serious consequences this therapy poses to mental health, particularly depression. We aimed to review the incidence and association between ADT in men with PCa and the risk of depression.
    METHODS: We systematically searched multiple databases, including MEDLINE, Scopus till August 2023 for studies that compared ADT versus control for treating PCa reporting depression as outcome. Meta-analysis was performed using random-effects models and results presented as odds ratios (ORs) with 95% confidence interval (CI). Quality assessment of the included studies was conducted using Joanna Briggs Institute critical appraisal checklists.
    RESULTS: A total of 38 studies (17 retrospective studies, 16 prospective studies, two cross-sectional studies and two randomized trials) with 360,650 subjects met the inclusion criteria and were included in this meta-analysis. The estimated pooled incidence of depression among ADT patients is 209.5 (95% CI = 122.3; 312.2) per 1000 patients. There is statistically significant relationship between ADT treatment and depression (OR = 1.46, 95% CI = 1.28, 1.67; p = 0, I2 = 86.4%). The results remained consistent across various subgroups. No risk of publication bias was detected by funnel plot and Eggers\'s test (p > 0.05).
    CONCLUSIONS: There is a higher risk of depression for men receiving ADT. Further studies evaluating optimal treatments for depression in men on ADT are warranted.

    子宫内膜癌(EC)是美国最常见的妇科恶性肿瘤,非典型子宫内膜增生(AEH)被认为是EC的高危前兆。激素疗法和子宫切除术是AEH和早期EC的实用治疗选择。一些患者出于诸如保留生育力或作为不良手术候选人的原因而喜欢激素治疗。然而,准确预测个体患者对激素治疗的反应将为这些疾病提供个性化和潜在改进的建议。这项研究旨在探索在子宫内膜组织样本的整个幻灯片图像(WSI)上使用深度学习模型来预测患者对激素治疗的反应的可行性。
    我们整理了来自两个临床站点的112名患者的临床WSI数据集。专家病理学家通过概述AEH/EC区域来注释这些图像。我们开发了一种具有混合监督的端到端机器学习模型。该模型基于从病理学家注释的AEH/EC区域提取的图像块。无监督的深度学习架构(自动编码器或ResNet50),或非深度学习(影像组学特征提取)用于将图像嵌入到低维空间中,其次是用于二进制预测的完全连接层,用病理学家建立的二元应答者/非应答者标签进行训练。我们使用分层抽样将数据集划分为开发集和测试集,以对我们模型的性能进行内部验证。
    自动编码器模型在独立测试集上产生的AUROC为0.80,95%CI[0.63,0.95],用于预测AEH/EC患者作为激素治疗的应答者与非应答者。
    这些发现证明了在WSI上使用混合监督机器学习模型来预测AEH/EC患者对激素治疗的反应的潜力。
    UNASSIGNED: Endometrial cancer (EC) is the most common gynecologic malignancy in the United States, and atypical endometrial hyperplasia (AEH) is considered a high-risk precursor to EC. Hormone therapies and hysterectomy are practical treatment options for AEH and early-stage EC. Some patients prefer hormone therapies for reasons such as fertility preservation or being poor surgical candidates. However, accurate prediction of an individual patient\'s response to hormonal treatment would allow for personalized and potentially improved recommendations for these conditions. This study aims to explore the feasibility of using deep learning models on whole slide images (WSI) of endometrial tissue samples to predict the patient\'s response to hormonal treatment.
    UNASSIGNED: We curated a clinical WSI dataset of 112 patients from two clinical sites. An expert pathologist annotated these images by outlining AEH/EC regions. We developed an end-to-end machine learning model with mixed supervision. The model is based on image patches extracted from pathologist-annotated AEH/EC regions. Either an unsupervised deep learning architecture (Autoencoder or ResNet50), or non-deep learning (radiomics feature extraction) is used to embed the images into a low-dimensional space, followed by fully connected layers for binary prediction, which was trained with binary responder/non-responder labels established by pathologists. We used stratified sampling to partition the dataset into a development set and a test set for internal validation of the performance of our models.
    UNASSIGNED: The autoencoder model yielded an AUROC of 0.80 with 95% CI [0.63, 0.95] on the independent test set for the task of predicting a patient with AEH/EC as a responder vs non-responder to hormonal treatment.
    UNASSIGNED: These findings demonstrate the potential of using mixed supervised machine learning models on WSIs for predicting the response to hormonal treatment in AEH/EC patients.
