在本项研究中,团队利用给癌细胞高效输送抗癌剂的抗体-药物复合体技术,研发出能选择性聚集到癌组织的活性氧探针。这种探针用绿色和红色两种荧光分子修饰能和癌细胞特有表面抗原结合的抗体,观察两种荧光的强度就能评估出癌细胞及周围过氧化氢(活性氧的一种)的量。借助这种探针,研究人员发现癌组织内存在过氧化氢高浓度积聚的热点区域。而在此热点区域肿瘤出芽现象高频发生。肿瘤出芽指癌细胞从原发肿瘤脱离,进入肿瘤基质的现象。肿瘤出芽指示着癌症转移的初期阶段。研究人员认为,从机制上说,暴露于过氧化氢的癌细胞通过部分激活上皮间质转化,从过氧化氢高浓度热点区域逃离。这种逃逸机制在正常上皮细胞中不存在,但在大多数癌症中普遍存在。它揭示了癌细胞内在的应激防御程序。研究团队认为,癌细胞为了躲避对自己有害的活性氧,迈出了转移的第一步。

對於癌症高風險群,例如有家族病史,或是環境汙染(例如輻射屋居民)的人進行基因檢測,可做較深入仔細的檢查分析,服用預防藥物。確定有癌症相關基因突變的人,可藉由預防性的手術,降低癌症機會。
Cytogenetics and immunohistochemistry are other kinds of tissue exams. These tests offer details about molecular adjustments (including mutations, fusion genes and numerical chromosome adjustments) and may So also suggest the prognosis and ideal treatment method.

免疫細胞療法是最近這幾年開發的最新技術,原理是直接將大量未分化的樹狀細胞投入腫瘤中或腫瘤周邊的血管中,能迅速且大量的強化樹狀細胞辨識特定癌細胞的能力,使樹狀細胞可在短時間內幫助輔助型T細胞(helper T mobile)快速誘導出大量細胞毒殺性T淋巴球(CTL),以攻擊特定癌細胞。目前此項研究已在日本進入臨床試驗階段。

The tissue prognosis in the biopsy suggests the type of mobile which is proliferating, its histological quality, genetic abnormalities and also other attributes. Alongside one another, this data is helpful to evaluate the prognosis and also to pick the greatest treatment.
