概括
患有多种遗传因素的前列腺癌患者面临着更高的早期死亡风险. 结合家族病史,多基因风险评分 (PRS) 和生活方式因素,可以确定有致命前列腺癌风险的男性.
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:
- 前列腺癌导致显著的死亡率,三分之一的死亡发生在75岁之前.
- 确定早期前列腺癌死亡的遗传和环境风险因素对于改善患者的治疗结果至关重要.
- 目前的风险分层需要加强早期致命结果,考虑到遗传和可修改因素.
研究的目的:
- 描述早期致命前列腺癌的遗传和生活方式风险因素.
- 为了改善前列腺癌患者早期致命结果的风险分层.
- 评估遗传倾向和生活方式对疾病死亡率的综合影响.
主要方法:
- 对来自两个具有生殖系遗传数据的前列腺癌患者的966名前列腺癌患者的分析.
- 对三个遗传因素的检查:家族史,多基因风险评分 (PRS) 和DNA修复基因的罕见变异.
- 使用后勤回归和10年风险计算,评估生活方式得分与早期致命结果的关联.
主要成果:
- 早期致死病例显示,家族病史 (23%对15%),高PRS (47%对36%) 和罕见变异 (14%对7.8%) 的患病率较高.
- 两个或两个以上的遗传因素显著增加了早期致命疾病的几率 (OR,3.5;95% CI,1.8-7.0).
- 没有遗传因素的男性患早期致命疾病的几率最低 (OR,0.3;95% CI,0.1-0.7).
结论:
- 结合家族病史,罕见变异,PRS和生活方式因素,可以提高早期致死和致命疾病风险的前列腺癌患者的鉴定.
- 这种多因素的方法有助于精确地分层攻击性前列腺癌的风险.
- 需要进一步的研究来验证这些发现,并将其纳入临床实践.

Cancer Prevention
6.0K
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.

Cancer Survival Analysis
311
Cancer survival analysis focuses on quantifying and interpreting the time from a key starting point, such as diagnosis or the initiation of treatment, to a specific endpoint, such as remission or death. This analysis provides critical insights into treatment effectiveness and factors that influence patient outcomes, helping to shape clinical decisions and guide prognostic evaluations. A cornerstone of oncology research, survival analysis tackles the challenges of skewed, non-normally...

Combination Therapies and Personalized Medicine
4.8K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
