概括

林奇综合征 (LS) 患有原发性结直肠癌 (CRC) 的患者面临超慢性CRC风险. 男性性别,年龄较大和左侧瘤增加了风险,影响了手术决定.

科学领域:

在瘤学瘤学.
遗传学遗传学是一个
外科胃肠道外科手术

背景情况:

林奇综合征 (LS) 是最常见的遗传性结直肠癌 (CRC) 综合征.
在LS患者中,初级CRC的外科治疗包括在扩展或部分切除术之间进行选择.
手术策略对LS患者中超慢性CRC风险的影响需要进一步阐明.

研究的目的:

在林奇综合征患者中确定甲时慢性CRC的关键风险因素.
评估手术切除术程度与甲时性CRC风险之间的关联.
为患有初级CRC的LS患者提供个性化的外科决策信息.

主要方法:

来自德国家族肠癌联盟的数据分析.
包括852名林奇综合征携带者,他们因原发性CRC而接受了扩大或部分切除.
应用考克斯回归模型来评估超慢性CRC风险,调整共变量.

主要成果:

在7.9年的中位数随访期间,观察到超慢性CRC的发病率为21.1%.
部分切除术显示,与扩展切除术相比,高风险的LS患者 (HR 3.78,P=.063) 的甲时慢性CRC风险增加趋势.
重要风险因素包括男性性别 (HR 2.16),诊断时的年龄 (HR 1.03) 和左侧瘤位置 (HR 1.53).

结论:

男性性别,年龄较大和左侧瘤是林奇综合征中甲时性CRC的重要危险因素.
手术方法可能会影响甲时慢性CRC风险,需要个性化患者咨询.
需要进一步的研究来优化LS患者的风险分层和长期结果.

Non-LTR Retrotransposons

Non-LTR Retrotransposons

As the name suggests, non-LTR retrotransposons lack the long terminal repeats characteristic of the LTR retrotransposons. Additionally, both LTR and non-LTR retrotransposons use distinct mechanisms of mobilization. Non-LTR retrotransposons are further divided into two classes - Long interspersed nuclear elements (LINEs) and short interspersed nuclear elements (SINEs), both of which occur abundantly in most mammals, including humans. Some of the active non-LTR retrotransposons in humans are L1...

Cancer Prevention

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.
Some...
