【广东会GDH基因检测】局部区域癌症扩散中胚胎发育的形态发生基因解码
靶向药基因检测两万有必要吗—标准
与专家交流如何选择有效的靶向药物治疗知道《Lancet Oncol》在. 2015 Mar;16(3):e148-51.发表了一篇题目为《局部区域癌症扩散中胚胎发育的形态发生领域》肿瘤靶向药物治疗基因检测临床研究文章。该研究由Michael Höckel 等完成。本体发生理论认为癌症是组织发育过程中特定阶段的病理性重活化和维持的临床表现。在成人有机体特征性的形态稳定状态下,这些发育程序被静默。在恶性进程中,这些程序以逆序运行,导致癌细胞渗透入越来越大的组织区域。然而,因为重活化的发生学程序需要拓扑定义的组织域来提供定位信息以便解释,局部肿瘤传播仅限于允许区(恶性细胞可以存活、迁移和增殖的组织域),这取决于恶性进程的状态。易受局部肿瘤侵袭的组织,即癌症领域,是对应胚胎发生学领域在成熟组织中的后代,带有相应的定位信息。该理论可在所有肿瘤中进行形态学和临床检验。理论验证将可显著提高预后评估和外科治疗。识别不同本体发生阶段肿瘤细胞的互补定位信息及其相关的癌症领域,可以成为进一步检验该理论的分子研究策略。促进了肿瘤的正确治疗与个性化用药的发展,进一步强调了基因信息检测与分析的重要性。
同国外肿瘤基因检测相比,优势是如何建立的:
区域癌症扩散,个体发生,癌场,形态发生场,恶变发生隔间
肿瘤靶向治疗基因检测临床应用结果
基因解码理论体中包括局疗区域癌症扩散的个体发生理论。局部区域癌症扩散的个体发生理论认为癌症是病理再激活和维持顺序发育程序的临床表现,该程序以前控制着癌症起源组织的逐步胚胎形态发生,背后的基因序列变化,包括驱动基因和乘客基因的突变是其基础,而这是基因检测的科学支撑。在以成年有机体为特征的形态静止状态下,这些程序被沉默了。在恶性进展期间,这些程序以逆行顺序运行,导致癌症浸润更大的组织区域。然而,由于重新激活的形态发生程序需要拓扑定义的组织域(形态发生场)来为其解释提供位置信息,因此局部肿瘤传播仅限于允许的隔间(恶性细胞可以存活、迁移和增殖的拓扑定义的组织域) ,这是由恶性进展的状态决定的。具有局部肿瘤扩散风险的组织,即癌场,是源自胚胎中相应形态发生场的成熟组织,其标记有各自的位置信息。该理论可以在所有肿瘤的形态学和临床上进行检验。对该理论的验证将为改善预后评估和手术治疗提供巨大的潜力。识别不同个体发育阶段的肿瘤细胞及其相关癌症领域的互补位置信息可能是进一步检验该理论的分子研究策略。
肿瘤发生与反复转移国际数据库描述:
The ontogenetic theory of locoregional cancer spread regards cancer as a clinical manifestation of the pathological reactivation and maintenance of the sequential developmental programmes that previously controlled the stepwise embryological morphogenesis of the tissue from which the cancer originated. In the state of morphostasis that characterises adult organisms, these programmes are silenced. During malignant progression, these programmes run in retrograde sequence, which leads to cancer infiltration of ever larger tissue areas. However, because the reactivated morphogenetic programmes need topologically defined tissue domains--morphogenetic fields--to provide positional information for their interpretation, local tumour propagation is confined to permissive compartments (topographically defined tissue domains where malignant cells can survive, migrate, and proliferate), which are determined by the state of malignant progression. The tissue at risk of local tumour spread, the cancer field, is the mature tissue derived from the corresponding morphogenetic field in the embryo, which is labelled with the respective positional information. The theory can be tested morphologically and clinically for all tumours. Verification of this theory would offer substantial potential to improve prognostic assessment and surgical treatment. Identification of the complementary positional information for tumour cells in different ontogenetic stages, and their associated cancer fields, could be a molecular research strategy to further test the theory.
