有關抑制癌細胞的原理,有沒有高人知道的呢?

抑制癌細胞長大最重要的是
抑制癌細胞長大最重要的是p53基因與NK Cell ,癌細胞長大需要利用醣類,細胞,血管,營養等,若P53基因異常則會利用血管內的營養物質加速癌細胞分化及生長並降低受攻擊之正常細胞自我修復能力

癌細胞開始分泌纖維蛋白原,此時就算是最高階影像醫學也無法偵測
適用於癌細胞初期0-0.2公分→預約檢測

mRNA標記檢測
癌細胞分化中期0.2公分-0.5公分 費用大約落在3到4萬之間

CTC ;Circulating Tumor Cell 循環腫瘤細胞液態切片檢測 本法為全球目前最新檢測技術 費用大約落在5-20左右

何謂循環腫瘤細胞 CTC ;Circulating Tumor Cell癌症轉移會有由原生腫瘤中脫離的癌細胞進入血液中,這些細胞稱為循環腫瘤細胞 (CTC),CTC數量會有動態變化,依據腫瘤本身變化以及對治療反應等,因此可用於體外早期診斷,藥物之快速評估,個體化治療等應用。

如何在最高階影像醫學之前發現未分化之癌細胞?

1.奈米攝影 偵測極限值目前為研究階段

2.正子攝影 偵測0.6公分以上癌細胞/大部分癌細胞具專一性/
特定癌細胞偽陽性高達26%/價格高/輻射劑量極高

3.核磁共振 偵測0.6公分以上癌細胞 有植入性金屬者無法使用,無法辨識傷疤,空腔器官肺癌、乳癌、大腸直腸癌辨識能力差

4.低劑量電腦斷層 偵測0.8公分以上癌細胞 肺癌檢出率較高

5.高階影像電腦斷層 偵測 0.9公分以上癌細胞 判讀誤差大,與病理報告相關性差,大量輻射相當於100張X光片

6.超高頻X光 偵測1公分以上癌細胞/篩檢用/有輻射疑慮

7. 超音波 偵測1公分以上癌細胞/顯示影像陰影/仰賴操作者經驗/易誤差
