靶向藥一個月費用排序

閱讀腫瘤啟動預防及反復抑制基因檢測，在消化科腫瘤正確治療專場聽到《Eur J Surg Oncol》在. 2006 Nov;32(9):954-60.發(fā)表了一篇題目為《血清微衛(wèi)星分析檢測食管腺癌》腫瘤靶向藥物治療基因檢測臨床研究文章。該研究由C F Eisenberger , N H Stoecklein, S Jazra, S B Hosch, M Peiper, P Scheunemann, J Schulte Am Esch, W T Knoefel等完成。研究食管腺癌的早期預警、轉移及反復特征的基因檢測，是醫(yī)學技術先進的大夫及醫(yī)院選用的腫瘤基檢測項目。

腫瘤靶向治療基因檢測臨床應用結果

食管腺癌腫瘤基因檢測研究的背景與目的：器官局限型食管癌在許多患者中早期可以治好，而更廣泛的病變預后較差。我們試圖通過使用一種新的分子方法開發(fā)一種用于癌癥檢測和評估患者預后的非侵入性測試。食管腺癌腫瘤基因檢測研究的材料和方法：從 32 例腺癌患者中獲得匹配的正常、腫瘤和血清樣本。食管。提取 DNA 并使用 12 個標記對樣品進行微衛(wèi)星分析。來自 10 名健康個體的血清和正常樣本作為對照。結果：32 名惡性腫瘤患者中有 27 名（84.4%）被發(fā)現(xiàn)在其原發(fā)腫瘤中有一個或多個微衛(wèi)星 DNA 改變。通過微衛(wèi)星分析，32 名患者中有 26 名（81.3%）的血清發(fā)生了改變。有趣的是，所有沒有淋巴轉移和三種早期癌（pT1pN0）的患者的血清中都顯示出 LOH 改變，而來自正常對照受試者的所有血清 DNA 均為陰性。存活率與腫瘤中的 LOH 或血清中的 LOH 均無顯著相關性。食管腺癌腫瘤基因檢測研究的結論：這些數(shù)據(jù)表明，血清樣本中的微衛(wèi)星 DNA 分析可能為早期發(fā)現(xiàn)食管癌提供潛在的有價值的工具。循環(huán)腫瘤 DNA 的證據(jù)反映了這些腫瘤擴散到遠處部位的傾向。到目前為止，隨訪時間仍然太短，無法就這一發(fā)現(xiàn)的預后影響得出進一步的結論。

Background and aims: Organ-confined oesophageal cancer in an early stage can be cured in many patients, whereas more extensive lesions have a poor prognosis. We sought to develop a non-invasive test for cancer detection and evaluation of the prognosis of the patients by using a novel molecular approach.Material and methods: Matched normal-, tumour- and serum-samples were obtained from 32 patients with adenocarcinoma of the oesophagus. DNA was extracted and the samples were subjected to microsatellite analysis using 12 markers. Serum and normal samples from 10 healthy individuals served as controls.Results: Twenty-seven of the 32 patients (84.4%) with malignant tumours were found to have one or more microsatellite DNA alterations in their primary tumour. Twenty-six of the 32 patients (81.3%) had alterations in the serum by microsatellite analysis. Interestingly, all patients without lymphatic metastasis and three early carcinomas (pT1pN0) already displayed LOH alteration in the serum, while all serum DNA of samples from normal control subjects were negative. Survival was not significantly correlated with either LOH in the tumour or LOH in the serum.Conclusion: These data suggest that microsatellite DNA analysis in serum specimens might provide a potentially valuable tool for early detection of oesophageal cancer. The evidence of circulating tumour DNA reflects the propensity of these tumours to spread to distant sites. Up to now the follow-up is still too short to draw further conclusions on the prognostic impact of this finding.
