阻断肿瘤代际遗传的临床应用结果

疾病的家族聚集性定义为疾病在某些家庭中的发生率超过预期在人群中的发生率。它已被证明适用于几种癌症类型，从罕见的癌症如与腺瘤病相关的结肠癌或李-弗拉美尼综合征到更常见的癌症如乳腺癌和结肠癌。然而，家族聚集只是一种流行病学模式，它并不能说明遗传或环境原因或两者结合是否导致家族聚集。家族聚集可能是由于对该疾病的遗传易感性，但暴露于环境因素（某些家族成员共有，但其他家族成员不共有）也可能导致家族聚集，因此在核研究中模拟遗传遗传。家庭。基于对生物过程中从接触致癌物开始到因播散性癌症死亡而结束的各个步骤的假设，基因解码基因检测建议遗传和环境因素可能都参与其中的大多数步骤。本论文侧重于区分基因和家庭环境在癌症发展中的影响所必需的研究基因解码基因检测的研究方法。

肿瘤在上下几代之间同时发生的研究国际数据库描述：

Familial clustering of a disease is defined as the occurrence of the disease within some families in excess of what would be expected from the occurrence in the population. It has been demonstrated for several cancer types, ranging from rare cancers as the adenomatosis-coli-associated colon cancer or the Li-Fraumeni syndrome to more common cancers as breast cancer and colon cancer. Familial clustering, however, is merely an epidemiological pattern, and it does not tell whether genetic or environmental causes or both in combination are responsible for the familial clustering. Familial clustering may be due to genetic predisposition to the disease, but exposure to environmental factors--shared by members of some families, but not by members of other families--may also cause familial clustering and hence mimic genetic inheritance in the study of nuclear families. Based on assumptions regarding the individual steps in the biological process starting with exposure to carcinogens and ending with death from disseminated cancer we suggest that genetic and environmental factors may both be involved in most of these steps. The present paper focuses on research methodologies necessary to discriminate between the effect of genes and family environment in the development of cancer.
