简介：分发评价是很重要的以便基于这分布为参数或它的函数做统计推理。例如，在这个工作，我们与非光滑的辅助信息建议某变量的分发的一个评估者这个变量的对称的分布。一种变光滑的技术被采用处理非可辨的功能。因此，分布能基于弄平的辅助信息被估计。分发评估者的Asymptotic性质被导出并且分析。没有这些辅助信息，分发评估者基于我们的方法被发现比相应评估者显著地有效。一些模拟研究被进行说明建议评估者的有限样品表演。

简介：AbstractObjective:Salivary gland tumors account for 6%-8% of head and neck neoplasms with the parotid gland as the most common primary site. Pleomorphic adenomas (PA) are considered the most common benign parotid gland neoplasms, followed by Warthin tumors (WT). The goal of this study was to investigate the distribution of parotid gland neoplasms among a United States veteran population.Design:Retrospective chart review.Setting:Washington DC Veterans Affairs Medical Center.Participants:Veterans who underwent fine needle aspiration (FNA) for a parotid gland mass from 2000 to 2018 were included. Medical records were reviewed for gender, age, tobacco use, surgery date, and pathology results.Main outcome measures:Changes in the distribution of parotid neoplasms and tobacco use over an 18-year period.Results:Of 141 patients with parotid gland masses, 86.5% (n = 122) were benign, 9.9% (n = 14) were malignant, and 3.5% (n = 5) were indeterminate. Of benign tumors, WT accounted for the majority at 51.6%, followed by PA at 40.2%. When stratified by decade (2000-2009 and 2010-2018), the proportion of WT compared to all other benign and malignant neoplasms increased from 31.6% to 53.6%, whereas the proportion of PA decreased from 36.8% to 33.3%. The rate of tobacco use was unchanged at approximately 32.0% among our cohort from 2000 to 2018.Conclusion:Among our cohort of veteran patients, WT was the most common benign parotid tumor and has increased in incidence over the last two decades despite an unchanged smoking rate.

简介：AbstractImportance:The diversity of pediatric genitourinary malignancies requires a timely resource detailing tumor characteristics and survival.Objective:To determine the incidence, demographics, and outcomes of all pediatric genitourinary tumors within the United States.Methods:A population-based search for patients diagnosed with genitourinary cancers under age 15 was performed using the National Cancer Institute’s Surveillance, Epidemiology, and End Results 18 registry. Information on primary tumor location, histologic type, patient age, sex, year of diagnosis, race, treatment, cause of death, and survival months was extracted. Descriptive epidemiological and survival statistics were calculated for all variables.Results:A total of 4576 cases from 1973 through 2015 were identified. The most common primary tumor sites were the kidney (80.3%), testis (12.3%), bladder (2.8%), and vagina (1.5%). Nephroblastoma (87.9%) and sarcoma (3.4%) were the most common renal malignancies. Rhabdomyosarcoma was common in the vagina, bladder, and testis at rates of 66.2%, 61.2%, and 24.6%, respectively. Germ cell tumors (71.0%) were the most common primary tumor of the testis. Ten-year overall survival (OS) for renal nephroblastoma and sarcoma was 88% and 82%, respectively. Ten-year OS for RMS of the testis was 91%, the bladder was 79%, the vagina was 79%, and the prostate was 56%. Germ cell tumor 10-year OS were 96% in the testis and 100% in the vagina.Interpretation:A better understanding of the overall distribution and outcomes associated with pediatric genitourinary cancers allows physicians to best understand the patient’s disease in the context of current frequency in a genitourinary setting and reported outcomes.
