概括
这项研究确定了肥胖和低胆固醇作为神经内分泌瘤 (NEN) 的潜在危险因素. 虽然吸烟和HbA1c与小细胞/大细胞肺癌有关,但没有发现新的遗传变异.
科学领域:
- 在瘤学瘤学.
- 遗传学 是一个遗传学.
- 流行病学 流行病学
背景情况:
- 全球神经内分泌瘤 (NENs) 发病率正在增加,临床和遗传风险因素的理解不足.
- 关于肥胖在NEN发展中的作用,存在相互矛盾的证据.
- 有限的研究利用前性收集的数据来调查NEN风险因素.
研究的目的:
- 使用英国生物银行数据,确定NEN的临床和生殖基因风险因素.
- 将NEN病例分为神经内分泌瘤 (NET),神经内分泌癌瘤 (NEC) 和小细胞/大细胞肺癌 (SLCLC).
- 探索临床表型,生殖系变体和NEN风险之间的关联.
主要方法:
- 利用英国生物银行癌症注册数据 (N≈500,000) 来识别NEN个病例.
- 用于癌症部位的ICD-O3代码和病例分层的组织学.
- 应用了Cox的比例危险模型和Regenie基因负担测试来分析临床和遗传数据.
主要成果:
- 确定了704个NET,340个NEC和550个SLCLC病例.
- 肥胖 (BMI,腰比) 和较低的胆固醇 (LDL,HDL,总量) 与NEN风险的关联显著,尽管边际.
- 吸烟和HbA1c与SLCLC相关;在社会经济调整后,空气污染没有显著的相关性.
- 复制了 MEN-1 变体和 NEC 之间的已知生殖系关联;没有检测到新的外体变体关联.
结论:
- 这是第一个大型前性基于人群的研究,确定了NEN的潜在临床和遗传风险因素.
- 需要进一步的研究来证实观察到的关系的因果关系.
- 外体研究没有足够的力量;未来的研究应该专注于对大型数据集的元分析.

01:37Neural Regulation
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.
02:18Cancer
Cancers arise due to mutations in genes involved in the regulation of cell division, which leads to unrestricted cell proliferation. Modern science and medicine have made great strides in the understanding and treatment of cancer, including eradicating cancer in some patients. However, there is still no cure for cancer. This is largely due to the fact that cancer is a large group of many diseases.
02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
