    目的:直到2018年3月,在我们机构,高危局限性前列腺癌患者接受了高剂量率近距离放射治疗(HDR-BT)联合外照射放射治疗(EBRT),而没有额外的激素治疗(HT)。在这项研究中,我们旨在评估该治疗的长期结局.
    方法:在1997年4月至2021年3月期间接受HDR-BT和EBRT并随访至少6个月的前列腺癌患者被纳入研究。根据国家综合癌症网络指南将高危人群分为五个级别。EBRT和HDR-BT剂量为39-45Gy/13-25分。和16.5-22Gy/2-4分数,分别。在初始治疗期间没有患者接受HT。Kaplan-Meier方法用于估计生化免于失败(bFFF),特定原因生存(CSS),和总生存率(OS)。还确定了生化失败。
    结果:72名患者被纳入研究,中位随访时间为91.9个月。中位年龄和初始前列腺特异性抗原(iPSA)水平为71岁和10.95ng/mL,分别。HDR-BT加EBRT的中位生物学有效剂量为270.3Gy。5年和7年的bFFF,CSS,OS率分别为85.2%和74.2%,100和100%,95.7%和91.9%,分别。只有iPSA≤20组与较高的bFFF率相关。iPSA≤20和iPSA>20的7年bFFF率为86.6%和48.6%,分别。
    结论:HDR-BT加不含HT的EBRT可能是高危局限性前列腺癌且iPSA水平≤20的患者的替代治疗选择。需要进一步的研究来验证这种治疗策略的有效性。
    OBJECTIVE: Until March 2018, patients with high-risk localized prostate cancer had been administered high-dose-rate brachytherapy (HDR-BT) combined with external beam radiotherapy (EBRT) without additional hormone therapy (HT) at our institution. In this study, we aimed to evaluate long-term outcomes of this treatment.
    METHODS: Patients with prostate cancer who received HDR-BT and EBRT between April 1997 and March 2021 and who were followed up for at least 6 months were included in the study. High-risk groups were classified into five levels according to the National Comprehensive Cancer Network guidelines. The EBRT and HDR-BT doses were 39-45 Gy/13-25 fractions. and 16.5-22 Gy/2-4 fractions, respectively. None of the patients received HT during initial treatment. The Kaplan-Meier method was used to estimate biochemical freedom from failure (bFFF), cause-specific survival (CSS), and overall survival (OS) rates. Biochemical failure was also determined.
    RESULTS: Seventy-two patients were enrolled in the study, with a median follow-up of 91.9 months. The median age and initial prostate-specific antigen (iPSA) level were 71 years and 10.95 ng/mL, respectively. The median biologically effective dose for HDR-BT plus EBRT was 270.3 Gy. The 5- and 7-year bFFF, CSS, and OS rates were 85.2 and 74.2%, 100 and 100%, and 95.7 and 91.9%, respectively. Only the iPSA ≤ 20 group was associated with the higher bFFF rate. The 7-year bFFF rates in the groups with iPSA ≤ 20 and iPSA > 20 were 86.6 and 48.6%, respectively.
    CONCLUSIONS: HDR-BT plus EBRT without HT might be an alternative treatment option for patients with high-risk localized prostate cancer and iPSA levels ≤ 20. Further studies are required to validate the efficacy of this treatment strategy.

    硬皮病是一种以炎症和血管异常为特征的多系统疾病,和过度纤维化。进行性系统性硬化症(PSS)主要随皮肤进展,接头,肺,心,和肾脏受累。在局部硬皮病和PSS中,脑血管的受累很少见。短暂性脑缺血发作和中风是硬皮病的罕见并发症。
    我们介绍了一位60岁的中风患者,患有局限性硬皮病,表现为言语障碍,忘记单词,偶尔会暂时失忆.
    在我们介绍的情况下,在缺血性危险因素方面进行的临床和实验室检查中未发现病理.皮肤表现包括挛缩,皮肤活检结果,与硬皮病相关的抗体阳性。鉴于硬皮病目前的发病机制,病人怀疑中风。
    UNASSIGNED: Scleroderma is a multisystemic disorder characterised by inflammatory and vascular anomalies, and excess fibrosis. Progressive systemic sclerosis (PSS) mainly progresses with skin, joint, lung, heart, and kidney involvement. Involvement of cerebral vessels is rare in both localised scleroderma and PSS. Transient ischemic attack and stroke are rare complications of scleroderma.
    UNASSIGNED: We present a 60-year-old stroke patient with localised scleroderma presenting with impaired speech, forgetting words, and occasional temporary memory loss.
    UNASSIGNED: In the case we present, no pathology was found in the clinical and laboratory tests performed in terms of ischemic risk factors. Skin findings included contracture, skin biopsy results, and antibody positivity related to scleroderma. Given the current pathogenesis of scleroderma, the patient was suspected of having a stroke.

    背景:间变性淋巴瘤激酶(ALK)阳性组织细胞增生症(ALK-H)是组织细胞肿瘤类别中的新兴实体,2008年首次报道为3名婴儿的多系统疾病。ALK-H的临床病理范围已扩展到包括特定器官的局部疾病,但这种亚型的特征并不为人所知。作者报告1例位于中枢神经系统的ALK-H难以治疗,并复习相关文献。
    方法:作者回顾了他们研究所的存档组织细胞肿瘤,发现了一例位于小脑半球的ALK-H患儿病例,以前曾报道过这种病例为组织细胞肉瘤。化疗(约1年),额外的手术,和常规化疗(大约2.5年)导致临床缓解,并继续维持化疗(约1.5年).完成治疗三年后,在大脑半球发现了一个高级别神经胶质瘤,2年后患者死于胶质瘤.
    结论:尽管根据以前的病例,ALK-H的预后通常良好,作者\'病例需要长期常规化疗,提示肿瘤表现出侵袭性特征。ALK抑制剂的早期给药可能是必要的。
    BACKGROUND: Anaplastic lymphoma kinase (ALK)-positive histiocytosis (ALK-H) is an emerging entity in the category of histiocytic neoplasms that was first reported as a multisystemic disease in three infants in 2008. The clinicopathological spectrum of ALK-H has been expanded to include localized disorders in specific organs, but the features of this subtype are not well known. The authors report a case of ALK-H localized in the central nervous system that was difficult to treat and review the relevant literature.
    METHODS: The authors reviewed archival histiocytic tumors at their institute and found a pediatric case of ALK-H localized in a cerebellar hemisphere that had previously been reported as histiocytic sarcoma. Chemotherapy (approximately 1 year), additional surgery, and conventional chemotherapy (approximately 2.5 years) led to clinical remission, and maintenance chemotherapy was continued (approximately 1.5 years). Three years after completing treatment, a high-grade glioma was found in a cerebral hemisphere, and the patient died of the glioma 2 years later.
    CONCLUSIONS: Although the prognosis of ALK-H is generally good according to prior cases, the authors\' case required long-term conventional chemotherapy, suggesting the tumor displayed aggressive characteristics. Early administration of ALK inhibitors may be necessary.

    纵向红斑狼疮(LE)被定义为指甲的纵向红色带,并且被分类为局部的(一个指甲受累)或多指的(一个以上的指甲受累)。这些分类的鉴别诊断是不同的。局部纵行性红斑狼疮(LLE)的病因最常见的是良性甲下肿瘤,很少见恶性肿瘤。多指纵行性甲沟炎(PLE)通常继发于区域性或全身性疾病,包括扁平苔藓和达里尔病。LE是常见的,但未被认可的临床发现。鉴于恶性肿瘤和相关全身性疾病的可能性,有必要提高皮肤科医生对LE的临床特征和鉴别诊断的认识。在这篇临床综述中,临床特征,鉴别诊断,评估,并对LE的管理进行了描述。
    Longitudinal erythronychia (LE) is defined as a longitudinal red band of the nail(s) and is classified as localized (involvement of 1 nail) or polydactylous (involvement of more than 1 nail). The differential diagnosis is distinct for these classifications. The etiologies of localized longitudinal erythronychia are most frequently benign subungual neoplasms and less often malignancies. Polydactylous longitudinal erythronychia is typically secondary to regional or systemic diseases, including lichen planus and Darier disease. LE is a common but underrecognized clinical finding. Increased dermatologist awareness of the clinical characteristics and differential diagnosis for LE is necessary given the possibility for malignancy and associated systemic disease. In this clinical review, the clinical features, differential diagnosis, evaluation, and management of LE are described.

    这里,我们报告了左无名指近端指间关节反复肿胀和疼痛的情况,后来被诊断为一名年轻成年女性的局部腱鞘巨细胞瘤。第一次出现是在四年前的同一解剖部位。演示时的检查显示,左无名指的掌侧有一个坚硬的肤色结节。可以看出,肿胀部分附着在下面的结构上,并且没有触痛。经过仔细的体格检查和手部的X光片成像,两种鉴别诊断为腱鞘膜巨细胞瘤和神经节囊肿。进行了手术切除,组织病理学评估显示与腱鞘膜巨细胞瘤一致的特征,本地化类型。切除边缘明确肿瘤。患者无术中或术后并发症。建议术后物理治疗。术后随访1年无复发。该报告强调了组织病理学评估和明确手术切缘确认在腱鞘膜巨细胞瘤治疗中的重要性。在复发病例中,切缘清晰的手术再切除可提供良好的临床结果.手术切除前,应告知患者病变的生物学性质和高复发风险.还应与患者讨论预防复发的管理方式以及长期随访的必要性。
    Here, we report the case of recurrent swelling and pain in the proximal interphalangeal joint of the left ring finger, which was later diagnosed as a localized tenosynovial giant cell tumor in a young adult female. The first presentation was at the same anatomical site four years prior. Examination at presentation showed a firm skin-colored nodule in the volar aspect of the left ring finger. The swelling was seen to be partly attached to underlying structures and was non-tender. After a careful physical examination and plain radiograph imaging of the hand, the two differential diagnoses considered were tenosynovial giant cell tumor and ganglion cyst. A surgical excision was performed, and histopathologic evaluation showed features consistent with a tenosynovial giant cell tumor, localized type. The resection margins were clear of tumor. The patient had no intraoperative or postoperative complications. Postoperative physiotherapy was recommended. No recurrence was seen after postoperative surgical follow-up for one year. This report highlights the importance of histopathologic evaluation and confirmation of clear surgical margins in the management of tenosynovial giant cell tumors. In recurrent cases, surgical re-excision with clear margins provides good clinical outcomes. Before surgical excision, patients should be informed about the biologic nature of the lesion and the high risk of recurrence. The management modalities to prevent recurrence and the need for long-term follow-up should also be discussed with the patient.

    背景:国际前列腺癌分期合作(STAR-CAP)已被提出作为前列腺癌的风险模型,与目前的分期系统相比具有更高的预后能力。这项研究旨在评估STAR-CAP在预测初始治疗后后续治疗风险和发展转移风险方面的表现。
    方法:该研究包括来自机构观察登记的3425名男性,中位年龄为64.9岁,中位随访时间为5.4年。主要终点是转移和初始治疗后进展到额外治疗(放射±手术)。使用竞争风险模型(死亡)估计STAR-CAP组的进展风险。
    结果:结果显示,STAR-CAP1A-1C期患者需要额外治疗和发生转移的风险相似。与阶段IC相比,从2A到3B的每个阶段都会逐渐增加后续治疗的风险(风险比(HR)分别为1.4~5.8)和转移的风险(HR分别为1.5~10.8).IC期患者接受后续治疗的5年概率为8.6%,对于2A至3B阶段的人,从11.4%增加到37.4%。IC期患者发生转移的5年概率为1.5%,对于2A至3B期的患者,这一比例从2.2%增加到8.2%。
    结论:接受手术的患者接受后续治疗的可能性更高,而放射治疗患者更有可能接受前期强化多模式治疗。
    The International Staging Collaboration for Prostate Cancer (STAR-CAP) has been proposed as a risk model for prostate cancer with superior prognostic power compared to the current staging system. This study aimed to evaluate the performance of STAR-CAP in predicting the risk of subsequent therapy after initial treatment and the risk of developing metastases.
    The study included 3425 men from an institutional observational registry with a median age of 64.9 years and a median follow-up time of 5.4 years. The primary endpoints were metastases and progression to additional therapy after initial therapy (radiation ± surgery). The risk of progression in the STAR-CAP group was estimated using a competing risk model (death).
    The results showed that patients with STAR-CAP stages 1A-1C had a similar risk of requiring additional therapies and developing metastasis. Compared to stage IC, each stage from 2A to 3B incrementally increased the risk of subsequent therapy (hazard ratio (HR) 1.4-5.8, respectively) and metastases (HR 1.5-10.8, respectively). The 5-year probability of receiving subsequent therapy for a patient with stage IC was 8.6%, which increased from 11.4% to 37.4% for those with stages 2A to 3B. The 5-year probability of developing metastases for patients with stage IC was 1.5%, which increased from 2.2% to 8.2% for patients with stages 2A to 3B.
    The probability of receiving subsequent therapy was higher for patients undergoing surgery, while radiation therapy patients were more likely to receive treatment with intensified multimodality therapies upfront.

    尽管近年来在治疗策略和手术方法方面取得了进展,在接受根治性治疗的食管胃癌(EGC)患者中,改善生存结局仍然是未满足需求的重要领域.最近出现的辅助免疫疗法作为切除的EGC的护理标准证明了免疫疗法在改善无复发生存率方面的影响。新辅助和围手术期免疫疗法代表了另一种有希望的方法,与辅助疗法相比具有潜在的优势。尽管早期新辅助免疫疗法研究取得了有希望的结果,有几个挑战和未来的研究需求。最佳时机,与手术相关的持续时间和剂量数量以及免疫疗法的最佳组合仍不清楚.此外,需要进行严格的相关研究,以确定用于患者选择和治疗反应预测的生物标志物,从而最大限度地发挥新辅助免疫治疗的益处.在这次审查中,我们简要总结了目前可切除EGC的治疗标准,并讨论了在这种情况下使用免疫检查点抑制剂的理由,以及这些新疗法的临床前和早期临床数据.最后,我们将研究免疫治疗在治疗模式中的潜在作用和未来方向,以及未来的挑战和机遇。
    Despite advances in treatment strategies and surgical approaches in recent years, improving survival outcomes in esophagogastric cancer (EGC) patients treated with curative intent remains a significant area of unmet need. The recent emergence of adjuvant immunotherapy as the standard of care for resected EGC demonstrates the impact of immunotherapy in improving recurrence-free survival. Neoadjuvant and perioperative immunotherapies represent another promising approach with potential advantages over adjuvant therapy. Despite the promising results of early neoadjuvant immunotherapy studies, there are several challenges and future research needs. The optimal timing, duration and number of doses in relation to surgery and the optimal combination of immunotherapies are still unclear. In addition, rigorous correlative studies need to be performed to identify biomarkers for patient selection and treatment response prediction to maximize the benefits of neoadjuvant immunotherapy. In this review, we provide a concise summary of the current standard of care for resectable EGC and discuss the rationale for the use of immune checkpoint inhibitors in this setting and the pre-clinical and early clinical data of these novel therapies. Finally, we will examine the potential role and future direction of immunotherapy in the treatment paradigm and the perceived challenges and opportunities that lay ahead.

  • 文章类型: Randomized Controlled Trial
    目的:前列腺癌(PC)是影响全球男性健康的重要疾病。超过60%的65岁以上的患者和超过80%的患者被诊断为局部PC。目前局部PC的治疗方式选择以及过度治疗是否存在争议。因此,我们希望构建一个列线图来预测局部PC老年患者的癌症特异性生存率(CSS)和总生存率(OS)相关危险因素,同时评估局部PC老年患者手术和放疗的生存率差异.
    方法:从监测中获得65岁以上局限性PC患者的数据,流行病学,和结束结果(SEER)数据库。使用单变量和多变量Cox回归模型来确定CSS和OS的独立危险因素。使用多变量Cox回归模型构建预测CSS和OS的列线图。一致性指数(C指数),受试者工作特性曲线下的面积(AUC),和校准曲线用于检验预测模型的准确性和区分度。使用决策曲线分析(DCA)来测试该模型的潜在临床价值。
    结果:从2010年到2018年,共有90,434名65岁以上的患者被诊断为局部PC。将所有患者随机分配到训练集(n=63,328)和验证集(n=27,106)。单因素和多因素Cox回归模型分析表明,种族,婚姻,T级,外科,放射治疗,前列腺特异性抗原(PSA),Gleason评分(GS)是预测老年局限性PC患者CSS的独立危险因素。年龄,种族,婚姻,手术,放射治疗,PSA,GS和GS是预测老年局限性PC患者OS的独立危险因素。预测的CSS的训练和验证集的c指数分别为0.802(95CI:0.788-0.816)和0.798(95CI:0.776-0.820)。用于预测OS的训练和验证集的c指数为0.712(95%:0.704-0.720)和0.724(95%:0.714-0.734)。这表明列线图具有良好的判别能力。AUC和校准曲线也显示出良好的准确性和可辨别性。
    结论:我们开发了新的列线图来预测患有局部PC的老年患者的CSS和OS。经过内部验证和外部时间验证,具有合理的准确性,可靠性和潜在临床价值,该模型可用于临床辅助决策。
    OBJECTIVE: Prostate cancer (PC) is a significant disease affecting men\'s health worldwide. More than 60% of patients over 65 years old and more than 80% are diagnosed with localized PC. The current choice of treatment modalities for localized PC and whether overtreatment is controversial. Therefore, we wanted to construct a nomogram to predict the risk factors associated with cancer-specific survival (CSS) and overall survival (OS) in elderly patients with localized PC while assessing the survival differences in surgery and radiotherapy for elderly patients with localized PC.
    METHODS: Data of patients with localized PC over 65 years were obtained from the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate Cox regression models were used to determine independent risk factors for CSS and OS. Nomograms predicting CSS and OS were built using multivariate Cox regression models. The consistency index (C-index), the area under the subject operating characteristic curve (AUC), and the calibration curve were used to test the accuracy and discrimination of the prediction model. Decision curve analysis (DCA) was used to test the potential clinical value of this model.
    RESULTS: A total of 90,434 patients over 65 years and diagnosed with localized PC from 2010 to 2018 were included in the study. All patients were randomly assigned to the training set (n = 63,328) and the validation set (n = 27,106). Univariate and multivariate Cox regression model analysis showed that age, race, marriage, T stage, surgical, radiotherapy, prostate-specific antigen (PSA), and Gleason score (GS) were independent risk factors for predicting CSS in elderly patients with localized PC. Age, race, marriage, surgery, radiotherapy, PSA, and GS were independent risk factors for predicting OS in elderly patients with localized PC. The c-index of the training and validation sets for the predicted CSS is 0.802(95%CI:0.788-0.816) and 0.798(95%CI:0.776-0.820, respectively). The c-index of the training and validation sets for predicting OS is 0.712(95%:0.704-0.720) and 0.724(95%:0.714-0.734). It shows that the nomograms have excellent discriminatory ability. The AUC and the calibration curves also show good accuracy and discriminability.
    CONCLUSIONS: We have developed new nomograms to predict CSS and OS in elderly patients with localized PC. After internal validation and external temporal validation with reasonable accuracy, reliability and potential clinical value, the model can be used for clinically assisted decision-making.
