腫瘤靶向治療基因檢測臨床應用結果

循環(huán)腫瘤 DNA (ctDNA) 已被用于監(jiān)測接受靶向藥物突變治療的非小細胞肺癌 (NSCLC) 患者的臨床過程。然而，盡管提供了關于 NSCLC 如何自然進展的寶貴信息，但 ctDNA 用于臨床過程監(jiān)測和預測沒有可藥物突變的初治 NSCLC 患者的臨床效用仍然未知。我們通過收集臨床信息、放射學數(shù)據(jù)和血漿樣本，縱向跟蹤了總共 12 名未接受過治療的 NSCLC 患者，這些患者沒有攜帶 EGFR 和 ALK 突變。相互比較了 ctDNA 水平和腫瘤負荷 (TB) 的變化。就診斷時的 ctDNA 檢測分析了新的轉移發(fā)展、體積倍增時間 (VDT) 和總生存期 (總生存期)。在 7 名 (58.3%) 患者的血漿中檢測到 ctDNA。在相當大一部分（57.1%）患者中，ctDNA 水平的變化與結核病相關，并且還與其他患者的腦轉移、腫瘤壞死或肺炎有關。所有進行 ctDNA 檢測的患者在隨訪期間在診斷時沒有轉移的器官中都出現(xiàn)了新的轉移。未檢測到 ctDNA 的患者未發(fā)生新的轉移（中位隨訪時間：9.8 個月）。此外，與未檢測到 ctDNA 的患者相比，檢測到 ctDNA 的患者 VDT 更短（p = 0.039），總生存期 更差（p = 0.019）?？梢酝ㄟ^測量 ctDNA 水平來監(jiān)測 NSCLC 進展的自然過程。診斷時檢測ctDNA可以預測NSCLC患者新轉移的發(fā)展、腫瘤快速生長和生存率低。監(jiān)測；非小細胞肺癌。

腫瘤發(fā)生與反復轉移國際數(shù)據(jù)庫描述：

Circulating tumor DNA (ctDNA) has been utilized to monitor the clinical course of patients of non-small-cell lung cancer (NSCLC) who receive therapies targeting druggable mutations. However, despite providing valuable information on how NSCLC would naturally progress, the clinical utility of ctDNA for clinical-course monitoring and prediction of treatment-na?ve NSCLC patients without druggable mutations remain unknown. We longitudinally followed a total of 12 treatment-na?ve NSCLC patients, who did not harbor?EGFR?and?ALK?mutations, by collecting clinical information, radiological data, and plasma samples. Changes in ctDNA levels and tumor burden (TB) were compared with each other. New metastasis development, volume doubling time (VDT), and overall survival (OS) were analyzed regarding ctDNA detection at diagnosis. ctDNA was detected in the plasma of seven (58.3%) patients. Changes in ctDNA levels correlated with those in TB in a substantial fraction (57.1%) of patients and was also associated with brain metastasis, tumor necrosis, or pneumonia in other patients. All patients with ctDNA detection developed new metastasis during follow-ups in the organs that had been devoid of metastasis at diagnosis. The patients without ctDNA detection did not develop new metastasis (median duration of follow-ups: 9.8 months). In addition, patients with ctDNA detection had shorter VDT (p?= 0.039) and worse OS (p?= 0.019) than those without ctDNA detection. The natural course of NSCLC progression can be monitored by measuring ctDNA levels. Detection of ctDNA at diagnosis can predict development of new metastasis, rapid tumor growth and poor survival of NSCLC patients.Keywords:?circulating tumor DNA; monitoring; non-small-cell lung cancer.
