概括
基因评估在26.6%的泌尿腺癌患者中发现了致病变体. 患有多种癌症的病史增加了基因测试结果的阳性,这表明更广泛的基因查尿癌.
科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 癌症研究 癌症研究
背景情况:
- 尿癌 (UC) 很少与遗传原因有关,但遗传因素越来越多.
- 目前对UC遗传评估的指导方针有限,重点关注早期发病或林奇综合征特征.
- 生殖系变异的全谱和UC的最佳遗传测试标准需要进一步阐明.
研究的目的:
- 在接受基因评估的尿路癌患者中调查致病性生殖系变异的流行率和谱.
- 确定与UC中遗传检测结果阳性相关的临床病理特征.
- 为了告知尿癌遗传评估标准的潜在扩展.
主要方法:
- 对128名被转诊进行遗传评估的泌尿腺癌患者 (2002-2024) 的回顾性分析.
- 记录遗传测试结果,变种流行率和临床病理特征.
- 利用费舍尔的精确测试来比较具有和没有致病性/可能致病性 (P/LP) 变体的患者之间的因素.
主要成果:
- 26.6%的患者有确定的P/LP变体,其中林奇综合征和DNA损伤修复基因是最常见的.
- 两个或两个以上额外的癌症史与阳性遗传测试有显著的关联 (P = .010).
- 遗传测试结果与诊断时的年龄,瘤位置或疾病初始阶段之间没有发现显著的关联.
结论:

Mutations
Overview
Single Nucleotide Polymorphisms-SNPs
A single nucleotide polymorphism or SNP is a single nucleotide variation at a specific genomic position in a large population. It is the most prevalent type of sequence variation found in the human genome. Point mutations that occur in more than 1% of the population qualify as SNPs. These are present once every 1000 nucleotides on an average in the human genome. Replacement of a purine with another purine (A/G) or a pyrimidine with another pyrimidine (C/T) is known as a transition. In contrast,...
Cancer Prevention
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

Sexually Transmitted Infections
Sexually transmitted infections (STIs) are diseases transmitted primarily through unsafe sexual interactions. Bacteria, viruses, or parasites cause them and can result in severe health complications if untreated.ChlamydiaThe bacterium Chlamydia trachomatis is responsible for the disease Chlamydia, the most common STI in the United States. This peculiar pathogen requires human cells to reproduce, residing intracellularly. The initial infection often goes unnoticed because it typically does not...
Nursing Assessment of the Genitourinary System I: Health History
The genitourinary system is critical to maintaining fluid balance, waste elimination, and reproductive function. Nurses play a vital role in assessing this system, beginning with a thorough health history. This process involves gathering patient information, identifying risk factors, and recognizing symptoms of genitourinary disorders. Early detection is vital for timely interventions and management.1. Gathering Patient InformationA complete health history includes the patient’s personal,...
Amebiasis
Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
