    废弃矿山(AML)是先前进行过矿物开采或加工的地区。在美国存在成千上万的AMLs。AML污染的径流会对周围陆地和水生生境和物种的生理和生态产生负面影响,并可能对人类健康有害。作为回应,一些美国联邦和州机构已经启动了评估与AMLs相关的健康风险的计划.在某些情况下,然而,AMLs可能对特定的野生动物类群有益。调查AMLs对野生动物的生理和生态影响的研究相对较少。我们进行了系统的审查,研究了已发表的科学文章,这些文章评估了AMLs对无脊椎动物和脊椎动物分类群的负面影响和积极影响。我们还提供有关评估AMLs的建议,以制定有效的缓解策略,以减少其对人类和野生动植物群落的负面影响。同行评审的出版物在WebofScience中进行了筛选,PubMed和GoogleScholar数据库。废弃的地雷通常对野生动物有害,不利影响范围从重金属的生物积累到生态适应性下降。相反,AMLs对受到威胁的蝙蝠种群具有整体利益,可以作为保护工具。研究在不同的野生动物类群中分布不均,呼应了额外的分类学多样化研究的必要性。我们建议使用标准化的野生动物调查方法来评估不同物种如何利用AMLs。联邦和州机构可以利用这些调查为各个反洗钱网站制定有效的补救计划,并将野生动物和人类的风险降至最低。
    Abandoned Mine Lands (AMLs) are areas where previous mineral extraction or processing has occurred. Hundreds of thousands of AMLs exist within the United States. Contaminated runoff from AMLs can negatively affect the physiology and ecology of surrounding terrestrial and aquatic habitats and species and can be detrimental to human health. As a response, several U.S. federal and state agencies have launched programs to assess health risks associated with AMLs. In some cases, however, AMLs may be beneficial to specific wildlife taxa. There is a relative paucity of studies investigating the physiological and ecological impacts of AMLs on wildlife. We conducted a systematic review examining published scientific articles that assessed the negative and positive impacts of AMLs across invertebrate and vertebrate taxa. We also offer suggestions on evaluating AMLs to develop effective mitigation strategies that reduce their negative tole on human and wildlife communities. Peer-reviewed publications were screened across WebofScience, PubMed and Google Scholar databases. Abandoned mine lands were generally detrimental to wildlife, with adverse effects ranging from bioaccumulation of heavy metals to decreased ecological fitness. Conversely, AMLs were an overall benefit to imperiled bat populations and could serve as tools for conservation. Studies were unevenly distributed across different wildlife taxa groups, echoing the necessity for additional taxonomically diverse research. We suggest that standardized wildlife survey methods be used to assess how different species utilize AMLs. Federal and state agencies can use these surveys to establish effective remediation plans for individual AML sites and minimize the risks to both wildlife and humans.

    肛周/会阴横纹肌肉瘤(PRMS)很少见,结果很差。一名29岁的女性出现会阴横纹肌肉瘤,发现双侧腹股沟淋巴结转移。当患者接受辅助表柔比星治疗时,发现疾病进展,异环磷酰胺,贝伐单抗治疗2个周期。经过3个周期的nivolumab,达卡巴嗪,顺铂,和长春碱治疗,患者出现部分缓解.进行手术切除。患者术前接受新辅助化疗,术后虚弱,所以他没有接受放化疗。由于广泛的腹腔内转移,患者在术后11个月后死亡。
    Perianal/perineal rhabdomyosarcomas (PRMS) is rare, and the outcome is poor. A 29-year-old female presented with perineal rhabdomyosarcomas revealed metastases to inguinal lymph nodes on the bilateral side. Disease progression was discovered when the patient got adjuvant epirubicin, ifosfamide, and bevacizumab for 2 cycles. After 3 cycles of nivolumab, dacarbazine, cisplatin, and vinblastine therapy, a partial response was identified in the patient. The surgical resection was performed. The patient received neoadjuvant chemotherapy before surgery and was weak after surgery, so he did not receive chemoradiotherapy. The patient succumbed after 11 months postoperatively due to widespread intraabdominal metastasis.

    高风险软组织肉瘤(STS)的治疗仍然是一个跨学科的挑战。区域性热疗(RHT)引起了人们的兴趣,因为它已被证明可以提高围手术期化疗(CTX)的总生存率。然而,关于如何将RHT最佳地整合到当前的多模式疗法中的问题出现了。
    我们根据系统评价和荟萃分析(PRISMA)指南的首选报告项目进行了系统文献综述。评估并纳入了以英语编写的研究,主要集中在放射性RHT和浅表热疗上。研究包括18岁以下患有转移性疾病的患者或评论文章,被排除在外。
    我们从1990年到2022年7月确定了15例临床报告。三篇文章结合了RHT+CTX,12例集中于联合RHT+放疗(RT)或新辅助放化疗(CRT)。大多数治疗都是基于侵入式测温,基于磁共振成像(MRI)的研究较少,四肢STS的无创测温。围手术期化疗用于RHT和CTX联合治疗,主要是基于异环磷酰胺的。RHT似乎增加了RT的有效性,特别是每周两次RHT会议。新辅助RHT和CRT的三模态同时方法也是可行的。没有报道RHT的显著毒性。
    收集的数据加强了RHT在多模态设置中的有益作用。需要进一步的专家共识和临床试验来确定RHT在治疗STS中的最佳整合。
    The therapy of high-risk soft tissue sarcomas (STS) remains an interdisciplinary challenge. Regional hyperthermia (RHT) sparked interest as it has been shown to improve overall survival when added to perioperative chemotherapy (CTX). However, questions arise on how RHT should be optimally integrated into current multi-modal therapies.
    We performed a systematic literature review according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Studies written in English and focused mainly on radiative RHT and superficial hyperthermia were evaluated and included. Studies including patients below the age of 18, with metastatic disease or review articles, were excluded.
    We identified 15 clinical reports from 1990 until July 2022. Three articles combined RHT + CTX, and twelve focused on combined RHT + radiotherapy (RT) or neoadjuvant chemoradiotherapy (CRT). Most treatments were based on invasive thermometry, and less on magnetic resonance imaging (MRI)-based, noninvasive thermometry for STS of the extremities. Perioperative chemotherapy was used for the combination of RHT and CTX, mostly Ifosfamide-based. The effectiveness of RT appeared to be increased by RHT, especially with two RHT sessions/week. The trimodal simultaneous approach of neoadjuvant RHT and CRT was also feasible. No significant toxicity of RHT was reported.
    The gathered data strengthen the beneficial role of RHT in the multimodal setting. Further expert consensus and clinical trials are required to determine the optimal integration of RHT in treating STS.

    背景:原发性上颌窦癌肉瘤(CS)是一种极其罕见的恶性肿瘤,其特征是双相组织学成分,缺乏规范化治疗,复发率高,预后不良。本文介绍1例原发性上颌窦CS及其治疗。
    方法:一名39岁女性患者于2018年3月21日主诉右侧面部疼痛和上颌牙齿麻木。计算机断层扫描检查显示恶性肿块,溶骨性破坏。术前活检提示肉瘤样癌或CS。2018年4月12日在全身麻醉下进行了右上颌全切术。最终分期为T3N0M0(ACJJ2019)。术后进行放疗和化疗。2018年5月26日,患者接受了第一个周期的阿霉素加异环磷酰胺。放疗前两天,患者接受了口腔内假体。从2018年6月20日至2018年8月22日,患者接受同步放化疗:放疗(60Gy分30次)和第二周期阿霉素。然后,患者接受了4个周期的阿霉素加异环磷酰胺治疗.患者随访39个月,无疾病迹象。
    结论:使用多学科治疗,临床分期T3N0M0(ACJJ2019)上颌窦CS可能取得良好预后。
    Primary maxillary sinus carcinosarcoma (CS) is an extremely rare malignant tumor characterized by biphasic histologic components, lack of standardized treatment, high recurrence rate, and poor prognosis. This paper presents a case of primary maxillary sinus CS and its treatment.
    A 39-year-old female patient complained of right facial pain and maxillary teeth numbness on March 21, 2018. Computed tomography examination revealed a malignant mass with osteolytic destruction. Preoperative biopsy suggested sarcomatoid carcinoma or CS. A total right maxillectomy under general anesthesia was performed on April 12, 2018. The final staging was T3N0M0 (ACJJ 2019). Postoperative radiotherapy and chemotherapy were performed. On May 26, 2018, the patient received the first cycle of doxorubicin plus ifosfamide. Two days before radiotherapy, the patient received an intra-oral prosthesis. From June 20, 2018, to August 22, 2018, the patient received concurrent chemoradiotherapy: radiotherapy (60 Gy in 30 fractions) and the second cycle of doxorubicin. Then, the patient received four cycles of doxorubicin plus ifosfamide. The patient was followed for 39 months with no evidence of disease.
    Using multidisciplinary therapy, clinical-stage T3N0M0 (ACJJ 2019) maxillary sinus CS may achieve a good prognosis.

    软组织肌上皮癌(MEC)是一种极其罕见的间充质肿瘤,除非获得完整的手术切除,否则预后较差。本研究报告了一例38岁的女性,在L2至L3的左侧椎旁区域患有椎体破坏。根据活检标本的分子病理学检查诊断MEC。因为预期治愈性手术会很困难,进行了联合化疗与阿霉素和异环磷酰胺和质子束治疗作为局部治疗,导致至少7.8年的长期生存。据我们所知,这是第一例软组织MEC,经典细胞毒性化疗和质子束治疗有效.尽管切缘阴性的手术切除是MEC的主要治疗方法,对于不可切除或晚期MEC患者,适当的基于多柔比星的全身治疗和大剂量放射治疗可能是可行的替代方案.分子病理特征之间关系的未来研究,包括生物标志物,和治疗剂的选择是必要的。
    Soft tissue myoepithelial carcinoma (MEC) is an extremely rare mesenchymal tumor that has a poor prognosis unless complete surgical resection is achieved. The present study reported a case of a 38-year-old woman with a tumor in the left paraspinal region at L2 to L3 with vertebral destruction. MEC was diagnosed based on molecular pathological examination of a biopsy specimen. Because curative surgery was expected to be difficult, a combination of chemotherapy with doxorubicin and ifosfamide and proton beam therapy as local therapy was performed, resulting in long-term survival for at least 7.8 years. To the best of our knowledge, this is the first case of soft tissue MEC for which classical cytotoxic chemotherapy and proton beam therapy were effective. Although surgical resection with negative margins is the mainstay of treatment for MEC, adequate doxorubicin-based systemic therapy and high-dose radiation therapy may be a feasible alternative in patients with unresectable or advanced MEC. Future studies on the relationship between molecular pathological features, including biomarkers, and the selection of therapeutic agents are warranted.

    背景:肿瘤溶解综合征是一种涉及多种代谢异常和临床症状如急性肾功能衰竭的肿瘤急症,心律失常,癫痫发作,多器官衰竭,如果不及时识别,可能是致命的。肿瘤溶解综合征最常见于血液系统恶性肿瘤患者,并且在肉瘤患者中描述的病例相对较少。
    方法:一名64岁的亚洲裔男性患者向其初级保健医生就诊,其右下肢肿块,最终被诊断为广泛转移性骨肉瘤。他接受了一个周期的顺铂和多柔比星治疗,并发高血容量和低氧性呼吸衰竭。考虑到体积过载,治疗改为单药,剂量减少的异环磷酰胺。在1小时内静脉注射1克/平方米(共1.8克)的异环磷酰胺后,病人出现肾衰竭,高尿酸血症,高钾血症,高磷酸盐血症,和乳酸性酸中毒.患者最终死于与肿瘤溶解综合征相关的严重电解质异常。
    结论:这是在接受异环磷酰胺单药治疗的骨肉瘤患者中首次描述的肿瘤溶解综合征。无论恶性肿瘤类型或化疗方案如何,临床医生都必须警惕识别肿瘤溶解综合征,以防止潜在的致命并发症。
    BACKGROUND: Tumor lysis syndrome is an oncologic emergency that involves multiple metabolic abnormalities and clinical symptoms such as acute renal failure, cardiac arrhythmias, seizures, and multiorgan failure, and may be fatal if not promptly recognized. Tumor lysis syndrome occurs most often in patients with hematologic malignancies, and relatively few cases have been described in patients with sarcoma.
    METHODS: A 64-year-old male of Asian heritage presented to his primary care physician with a right lower-extremity mass and was ultimately diagnosed with widely metastatic osteosarcoma. He was treated with one cycle of cisplatin and doxorubicin that was complicated by hypervolemia and hypoxic respiratory failure. Given concerns for volume overload, therapy was changed to single-agent, dose-reduced ifosfamide. After receiving one dose of ifosfamide 1 g/m2 (1.8 g total) intravenously over 1 hour, the patient developed renal failure, hyperuricemia, hyperkalemia, hyperphosphatemia, and lactic acidosis. The patient ultimately died from severe electrolyte abnormalities associated with tumor lysis syndrome.
    CONCLUSIONS: This is the first instance of tumor lysis syndrome described in a patient with osteosarcoma undergoing ifosfamide monotherapy. Clinicians must be vigilant in identifying tumor lysis syndrome regardless of the malignancy type or chemotherapy regimen in order to prevent potentially fatal complications.

    异环磷酰胺是可能导致高达30%的患者神经毒性的化疗方案之一。阿瑞吡坦在化疗中作为止吐剂给药,关于对CYP3A4的抑制作用,阿瑞吡坦可增加异环磷酰胺不良反应的风险。本研究旨在系统地研究异环磷酰胺诱导的神经毒性与阿瑞吡坦或福沙吡坦在化疗癌症患者中的关系。包括PubMed在内的四个数据库,Scopus,WebofScience,和Embase在没有语言限制的情况下进行了系统审查,并进行了手工搜索,直到2021年12月。共检索到1639份出版物,9项研究符合资格标准。对于质量评估,我们使用纽卡斯尔-渥太华质量评估量表(NOS)进行回顾性队列研究,并使用Cochrane协作工具评估一项随机对照试验的偏倚风险.总的来说,我们的系统评价结果表明神经毒性和同时使用异环磷酰胺和阿瑞匹坦或福沙吡坦之间的积极增强趋势,但相关性无统计学意义.正如我们的发现所表明的,多项研究确定低白蛋白是异环磷酰胺诱发脑病的危险因素.然而,需要对更多患者进行进一步的临床研究,以评估异环磷酰胺相关神经毒性和阿瑞吡坦或福沙吡坦的临床意义.
    Ifosfamide is one of the chemotherapy regimens which potentially causes neurotoxicity in patients up to 30%. Aprepitant is administered as an anti-emetic agent in chemotherapy and regarding the inhibitory effect on CYP3A4, aprepitant can increase the risk of ifosfamide adverse effects. This study aims to systematically investigate the relation of ifosfamide-induced neurotoxicity and aprepitant or fosaprepitant in chemotherapy cancer patients. Four databases including PubMed, Scopus, Web of Science, and Embase were systematically reviewed without language restriction and hand searching was performed until December 2021. Total 1639 publications were retrieved and nine studies fulfilled the eligibility criteria. For quality assessment, we used Newcastle-Ottawa quality assessment scales (NOS) for retrospective cohort studies and Cochrane Collaboration tool to assess the risk of bias for a randomized controlled trial. Overall, the results of our systematic review indicated a positive enhanced trend between neurotoxicity and concomitant use of ifosfamide and aprepitant or fosaprepitant, but the association was not statistically significant. As indicated by our findings, several studies identified low albumin as a risk factor for ifosfamide-induced encephalopathy. However, further clinical studies with a larger population of patients are required to evaluate the clinical significance of ifosfamide-related neurotoxicity and aprepitant or fosaprepitant.

    异环磷酰胺治疗后的脑病是一种描述良好的现象,通常用亚甲基蓝(MB)治疗。氯乙醛,据推测,一种具有潜在神经毒性的异环磷酰胺代谢物会导致这种脑病.目前的治疗指南是停止异环磷酰胺并提供支持性护理。MB具有抑制氯乙醛形成的作用,并已被描述为异环磷酰胺脑病的治疗和预防。MB在30分钟内有效,持续3天。在文献中没有描述长期脑病和MB治疗在治疗后持续超过30天。
    我们介绍了一名11岁女性,患有自闭症谱系障碍,并在异环磷酰胺治疗她的非生殖细胞生殖细胞肿瘤(GCT)后7个月反复出现严重嗜睡的情况。在接受头颅RT之前发生了嗜睡期。甲基溴的管理给予了立即但有限的回应,两次给药之间持续1-2天的嗜睡消退。神经影像学或实验室评估不能解释嗜睡,但脑电图提示持续性脑病.
    文献综述确定神经毒性是异环磷酰胺的副作用,但是这种效果并没有被描述为持续超过30天。我们的病例在停止治疗后继续需要用MB治疗7个月。我们报告了这些新的临床发现,并假设可能存在遗传/代谢成分将这种反应与异环磷酰胺与患者先前存在的自闭症联系起来。这种可能的关联也可能与自闭症和GCT发展之间已经建立的联系有关。这一假设导致进一步讨论异环磷酰胺在合并症儿童中的合适用法以及在使用前进行筛查的必要性。
    Encephalopathy following Ifosfamide treatment is a well-described phenomenon that is typically treated with Methylene Blue (MB). Chloroacetaldehyde, a potentially neurotoxic metabolite of Ifosfamide is hypothesized to cause this encephalopathy. Current guidelines for treatment is to stop Ifosfamide and provide supportive care. MB acts to inhibit Chloroacetaldehyde formation and has been described as a therapy and prophylaxis for Ifosfamide-encephalopathy. MB is effective within 30 min and lasts up to 3 days. Prolonged encephalopathy and MB therapy has not been described in the literature as lasting longer than 30 days following treatment.
    We present the case of an 11-year-old female with autistic spectrum disorder and recurrent episodes of severe somnolence for 7 months following Ifosfamide therapy for her Non-Germinomatous Germ Cell Tumor (GCT). Periods of somnolence occurred prior to receiving cranial RT. Administration of MB gave immediate but limited response, with resolution of somnolence lasting 1-2 days between administrations. The somnolence could not be explained by neuroimaging or laboratory evaluation, but EEG indicated persistent encephalopathy.
    A literature review determines that neurotoxicity is a side effect of Ifosfamide, but this effect has not been described persisting longer than 30 days. Our case continued to require treatment with MB for 7 months following cessation of therapy. We report these novel clinical findings, and hypothesize that there could be a genetic/metabolic component linking this reaction to Ifosfamide with the case patient\'s pre-existing autism. This possible association may also correlate to the already-established link between autism and the development of GCTs. This hypothesis leads to further discussion on the suitable usage of Ifosfamide in children with co-morbidities and the necessity of screening prior to its usage.

    外周T细胞淋巴瘤(PTCL)是一种侵袭性肿瘤,在儿科或青少年和年轻人(AYAs)中很少见,因此没有预先或复发的护理标准。作者描述了一名16岁的PTCL患者,化疗和自体干细胞移植治疗。一旦复发,他接受了异环磷酰胺,卡铂,依托泊苷,和辐射可持续缓解4年。儿科/AYAPCTL的数据仍然缺乏对生物学和微环境的了解,与成年患者的差异,缺乏足够的治疗。靶向治疗可以改善儿童和患有难治性或复发性PTCL的AYAs的预后。
    Peripheral T-cell lymphoma (PTCL) is an aggressive tumor, rarely seen in pediatrics or adolescent and young adults (AYAs) so there is no upfront or relapsed standard of care. The authors describe a 16-year-old with PTCL, treated with chemotherapy and autologous stem cell transplant. Upon relapse, he received ifosfamide, carboplatin, etoposide, and radiation with durable remission of 4 years. Data in pediatric/AYA PCTL continue to lack an understanding of the biology and microenvironment, the differences to adult patients, and a lack of adequate therapy. Targeted therapy may improve outcomes for children and AYAs with refractory or relapsed PTCL.

    肺泡横纹肌肉瘤(ARMS)是最常见的儿童软组织肉瘤,但在成年人中很少见。大多数成人协议是从儿科协议改编的。在这里,我们报告了一个53岁的女性被诊断患有鼻肺泡横纹肌肉瘤的病例,诊断时的IV期,通过化疗(该方案源自儿科方案pEpSSGRMS2005)治疗,导致部分反应,然后进行化疗。我们对成人头颈部ARMS进行了系统评价,发现29例。采用不同方案的主要化疗(VAC,应进行VAI或VIE),然后进行手术和/或外部束放疗(最好使用IMRT)。EBRT似乎对常规分级中剂量约为50Gy的每个ARMS都有益,最终完成了对残留肿瘤的加强。目标体积必须在化疗前成像时确定。近距离放射治疗和质子治疗正在评估中。
    Alveolar rhabdomyosarcoma (ARMS) represents the most common childhood soft tissue sarcoma, but they are rarely seen among adults. Most of the protocols for adults are adapted from pediatric protocols. Here we report a case of a 53-year-old woman diagnosed with a nasal alveolar rhabdomyosarcoma, stage IV at diagnosis, treated by chemotherapy (a regimen inspired from the pediatric protocole pEpSSG RMS 2005) which led to partial response followed by chemo-radiotherapy. We performed a systematic review of adult head and neck ARMS and found 29 cases. Primary chemotherapy with different protocols (VAC, VAI or VIE) should be done followed by surgery and/or external beam radiotherapy (preferably with IMRT). EBRT seems beneficial to every ARMS with a dose around 50Gy in a conventional fractionation, eventually completed with a boost on residual tumor. The target volume must be defined on pre-chemotherapy imaging. Brachytherapy and proton therapy are under evaluation.
