    一种罕见的局部侵袭性血管肿瘤,青少年鼻咽血管纤维瘤(JNA)主要影响男性青少年。本文描述了一名14岁的男性患者,他表现为嗜睡和复发性鼻出血,这是JNA的症状。CT和MRI扫描证实血管肿块具有明显的局部侵袭,起源于蝶腭孔。CT血管造影后,这揭示了肿瘤的大量血液供应,并有助于有效切除,设计了一个有针对性的手术策略。组织病理学证实了肿瘤的良性性质,手术成功,患者顺利康复。这个案例增加了关于JNA的小文献。它强调了医疗保健专业人员在管理疾病时需要了解早期识别和仔细的术前准备的要求。
    A rare and locally aggressive vascular tumor, juvenile nasopharyngeal angiofibroma (JNA) mostly affects male teenagers. This paper describes a 14-year-old male patient who presented with lethargy and recurrent nasal bleeding, which are symptoms of JNA. CT and MRI scans confirmed a vascular mass with a significant local invasion originating from the sphenopalatine foramen. After a CT angiography, which revealed the tumor\'s large blood supply and helped with efficient excision, a focused surgical strategy was designed. Histopathology verified the benign nature of the tumor, and the operation was successful and the patient had a smooth recovery. This case adds to the little literature on JNA. It highlights the need for healthcare professionals to be aware of the requirement of early identification and careful presurgical preparation in managing the illness.

    生活方式因素,包括吸烟,与肿瘤疾病有关,报道提示吸烟与某些肿瘤中FGFR(成纤维细胞生长因子受体)的过度表达之间存在关联。这项研究旨在评估有和没有吸烟史的患者FGFR3和FGFR4基因的表达。总共招募了118名参与者,包括83名青少年鼻咽血管纤维瘤(JNA)患者和35名健康参与者,将JNA患者进一步分层为吸烟者和非吸烟者.使用TRIzol试剂从血液和唾液样品中提取总RNA,并使用Nanodrop进行量化,然后使用RT-PCR对FGFR3/4进行基因表达分析。使用JNA的新鲜活检采用免疫组织化学分析来验证发现。所有实验一式三份进行,并使用卡方检验进行分析(P<0.05)。吸烟者在所有样品类型中表现出显著较低的总RNA浓度(P<0.001)。研究显示JNA患者中两种FGFR3/4基因均显著上调(P<0.05)。此外,FGFR3表达在吸烟者中显著高于66%(95%CI:53-79%),而非吸烟者为22%(95%CI:18-26%)。免疫组织化学分析表明吸烟者中FGFR3的中等至强染色强度。该研究强调了JNA患者中FGFR3/4基因的过度表达,在吸烟者中观察到更强的关联。此外,医学报告显示吸烟者的复发率和出血强度较高.这些发现强调了FGFR3作为JNA关键分子因子的潜在作用,特别是在吸烟的背景下。
    Lifestyle factors, including smoking, have been linked to neoplastic diseases, and reports suggest an association between smoking and overexpression of FGFR (fibroblast growth factor receptor) in certain neoplasms. This study aims to assess the expression of FGFR3 and FGFR4 genes in patients with and without a history of smoking.A total of 118 participants were recruited, including 83 Juvenile Nasopharyngeal Angiofibroma (JNA) patients and 35 healthy participants, the JNA patients were further stratified as smokers and nonsmokers. Total RNA was extracted from the blood & saliva sample by using TRIzol reagent, and quantified using a Nanodrop, and then subjected to gene expression analysis of FGFR3/4 using RT-PCR. Immunohistochemistry analysis was employed using fresh biopsies of JNA to validate the findings. All experiments were performed in triplicates and analysed using the Chi-Square test (P < 0.05). Smokers exhibited significantly lower total RNA concentrations across all sample types (P < 0.001). The study revealed significant upregulation of both FGFR3/4 genes in JNA patients (P < 0.05). Moreover, FGFR3 expression was significantly higher among smokers 66% (95% CI: 53-79%) compared to non-smokers 22% (95% CI: 18-26%). Immunohistochemistry analysis demonstrated moderate to strong staining intensity for FGFR3 among smokers. The study highlights the overexpression of FGFR3/4 genes in JNA patients, with a stronger association observed among smokers. Furthermore, medical reports indicated higher rates of recurrence and bleeding intensity among smokers. These findings emphasize the potential role of FGFR3 as a key molecular factor in JNA, particularly in the context of smoking.

    我们描述了第一例青少年鼻咽血管纤维瘤从促鼓室动脉接受血液供应,导致术中大出血。患者是一个12岁的男孩,患有Radkowski3BJNA。尽管外科医生由于无法控制的肿瘤出血而未能完全切除肿瘤,但我们利用了颈动脉外动脉的进料器的术前栓塞。在血管造影的回顾性分析中,仅发现了罪魁祸首。在一周后进行的第二次手术中切除肿瘤。尽管文献中描述了ICA分支的选择性栓塞,但数据很少,此类病例的处理也是如此。
    We describe the first case of juvenile nasopharyngeal angiofibroma receiving blood supply from caroticotympanic artery which resulted in catastrophic bleeding intraoperatively. The patient was an 12-year-old boy with a Radkowski stage 3B JNA. We utilized preoperative embolization of feeders from external carotid artery though the surgeon failed to excise the tumor completely due to uncontrollable bleeding from the tumor. On retrospective analysis of angiography only the culprit feeder found. Tumor was excised in the second surgery conducted a week later. Although selective embolization of ICA branches are described in literature the data are sparse and so is the management of such cases.

    The detection of androgen receptors within Juvenile Nasopharyngeal Angiofibroma (JNA) has prompted investigation of the role of Flutamide. The aim of this review is to evaluate Flutamide as a possible neo-adjuvant treatment for JNA. Literature searches were conducted using MEDLINE, EMBASE and Web of Science. The Joanna Briggs Institute (JBI) checklist was used to assess risk of bias. The Oxford Centre of Evidence-Based Medicine (OCEBM) Levels of Evidence was used to stratify the evidence level. Literature searches were conducted using MEDLINE, EMBASE and Web of Science. Flutamide as neo-adjuvant treatment potentially causes a reduction in JNA tumor volume by ≥ 25%. Based on the current limited evidence, Flutamide has a limited role in JNA management and further research is required. Its utilization should only follow discussion with the patient, their families, and within the multidisciplinary team.

    目的该研究的目的是使用国家儿科住院数据库评估术前血管栓塞(PVE)对青少年鼻咽血管纤维瘤(JNA)手术结果的影响。方法查询1997年至2016年JNA所有手术管理病例的医疗费用和利用项目儿童住院患者数据库。根据患者是否接受PVE对病例进行分层。在控制患者人口统计学因素和合并症的同时,使用多元线性回归预测PVE对住院时间(LOS)和总费用的影响。使用二元逻辑回归计算PVE患者接受围手术期输血的比值比(OR)。结果共有473例患者在此时间段内接受了JNA手术切除。PVE的使用率从1997年的0%增加到2016年的66%。发现PVE可将LOS降低1天(p=0.036),并降低需要围手术期输血的几率(OR=0.511,p=0.041)。接受PVE的患者被额外收取35,600美元(p<0.001),但2016年的最新数据表明,PVE的医院成本正在下降。结论JNA的PVE越来越普遍。栓塞导致医院LOS降低和需要输血的几率降低。虽然栓塞增加了管理成本,这一趋势应该重新评估,因为这一程序正变得越来越普遍。
    Objectives  The aim of the study is to evaluate the effect of preoperative vascular embolization (PVE) on juvenile nasopharyngeal angiofibroma (JNA) surgical outcomes using a national pediatric hospitalization database. Methods  The health care cost and utilization project Kids\' Inpatient Database was queried for all cases of operative management of JNA between the years of 1997 and 2016. Cases were stratified based on whether the patient received PVE. A multiple linear regression was used to predict the effect of PVE on hospital length of stay (LOS) and total cost while controlling for patient demographic factors and comorbidities. The odds ratio (OR) of receiving a perioperative blood transfusion was computed using a binary logistic regression for PVE patients. Results  A total of 473 patients who underwent JNA surgical resection in this time period were identified. The use of PVE has increased from 0% in 1997 to 66% of all cases by 2016. PVE was found to decrease LOS by 1 day ( p  = 0.036) and decrease the odds of needing a perioperative blood transfusion (OR = 0.511, p  = 0.041). Patients receiving PVE were charged an additional $35,600 ( p  < 0.001), but recent data in 2016 indicate that hospital costs for PVE are decreasing. Conclusion  PVE of JNA is becoming increasingly prevalent. Embolization results in decreased hospital LOS and lower odds of needing blood transfusions. While embolization increases the cost of management, this trend should be re-evaluated as this procedure is becoming more widespread.

    Juvenile nasopharyngeal angiofibroma (JNA) is a benign tumor of the nasal cavity that predominantly affects young boys. Surgical removal remains the gold standard for the management of this disease. Preoperative intra-arterial embolization (PIAE) is useful for reductions in intraoperative blood loss and surgical complications. In our series of 79 patients who underwent preoperative embolization from 1999 to 2020, demographics, procedural aspects, surgical management and follow-up outcome were analyzed. Embolization was performed in a similar fashion for all patients, with a superselective microcatheterization of external carotid artery (ECA) feeders and an injection of polyvinyl alcohol (PVA) particles, followed, in some cases, by the deployment of coils . Procedural success was reached in 100% of cases, with no complications such as bleeding or thromboembolic occlusion, and surgical intraoperative blood loss was significantly decreased. In conclusion, PIAE is a safe and effective technique in JNA treatment, minimizing intraoperative bleeding.

    Somatostatin receptors (SSTRs) are highly expressed in neuroendocrine tumors and is exploited for its imaging and treatment. SSTRs expression is also demonstrated in diverse benign and malignant tumor cell types and proliferating peri-tumoral vessels. Similarly, Juvenile Nasopharyngeal Angiofibroma (JNA) expresses different SSTRs and may be utilized for its imaging and treatment using DOTA, 1-Nal3-octreotide (DOTANOC)-PET/CT scan.
    Prospective cohort.
    Nineteen clinico-radiologically diagnosed primary JNA patients underwent a 68 Ga-DOTANOC PET-CT scan. Using a dedicated PET/CT scanner, a low-dose head and neck spot CT scan was performed after 45 to 60 minutes of intravenous injection of 2 to 3 mCi(74-111 MBq) of DOTANOC. The primary objective was to assess the intensity and pattern of DOTANOC uptake in these patients.
    DOTANOC expression was noted in all cases (n = 19) of primary JNA (100%). The mean (SD) DOTANOC SUVmax ratio of tumor and background was 6.9+/-1.4(range, 3.8-9.5). Intra-cranial extension in all 13/19 patients was prominently visualized due to the absence of DOTANOC uptake in the brain. Compared to the background all stages of JNA showed significant DOTANOC uptake (P < .0001). No difference in uptake between advanced-stage tumors and early tumors was noted (P = .47). A statistically non-significant negative trend was noted for decreasing uptake with increasing age (Spearman correlation coefficient, r = -0.19).
    This first study of 68 Ga-DOTANOC-PET/CT scan in JNA demonstrates consistent and reliable uptake activity in all patients irrespective of age and stage. This opens up possibilities to physiological diagnostic imaging with a promise of greater specificity and sensitivity and may have applications in ambivalent diagnostic situations such as the detection of recurrence.

    Juvenile nasopharyngeal angiofibroma (JNA) has a high recurrence rate after surgery. Cofilin overexpression is associated with increased tumor cell metastasis, and progression of various human cancers. However, studies on cofilin expression in JNA are rare. The purpose of this study was to investigate the expression and localization of cofilin in a tissue microarray (TMA) of JNA specimens. In addition, we also analyzed its correlation with clinicopathological features and recurrence.
    Immunohistochemistry was performed to detect cofilin expression in a TMA of samples from 70 JNA patients and 10 control subjects. The association between clinicopathological variables and cofilin immunostaining was analyzed using Pearson\'s chi-square test. Kaplan-Meier survival analysis was used to calculate the disease-free survival rate, and investigate the effect of cofilin expression on time to recurrence (TTR) in JNA patients. The Cox regression model was used for multivariate survival analysis.
    Cofilin was detected in irregular smooth muscle cells, pericytes, less differentiated stromal cells, and plump cells, but not in inactive fibroblasts and mature vascular endothelial cells of JNA specimens. The presence of cofilin in JNA was correlated with tumor stage (p = 0.012) and volume of intraoperative hemorrhage (p < 0.001). JNA patients with high cofilin expression had a higher recurrence rate than those with low cofilin expression (p = 0.012). Cofilin expression and patient\'s age were significant predictors of TTR, and cofilin was a better predictor for disease recurrence (area under the receiver operating curve [AUROC; 0.711; p = 0.005) than other clinicopathological features.
    Cofilin is an independent prognostic marker for JNA patients who have undergone surgical treatment and may represent a novel therapeutic target for extensive JNA.
