中文摘要:
      目的对比分析免疫组化(IHC)、荧光原位杂交(FISH)、实时荧光定量PCR(qRT-PCR)检测非小细胞肺癌(NSCLC)ALK融合基因情况。 方法收集453例NSCLC标本。随机选取IHC检测的ALK融合基因不同表达程度标本40例,采用FISH和qRT-PCR法分别检测各组ALK融合基因表达水平,并进行一致性分析。 结果IHC与FISH、qRT-PCR的ALK融合基因检测结果比较,IHC ALK(-)/(3+)与FISH、qRT-PCR检测结果一致率均为100%,具有高度一致性(r=0.781、r=0.740,P<0.05)。FISH与qRT-PCR的检测结果一致率为97.5%,具有高度一致性(r=0.943,P<0.05)。 结论FISH、qRT-PCR法与IHC法检测在不同表达程度ALK融合基因样本中检测结果存在差别,IHC敏感性更高。FISH、qRT-PCR法在ALK融合基因样本的检测结果具有高度一致性。
英文摘要:
      AimTo comparatively analyze the detection of ALK fusion gene in non-small cell lung cancer (NSCLC) using immunohistochemistry (IHC), fluorescence in situ hybridization (FISH), real-time quantitative polymerase chain reaction (qRT-PCR). MethodsA total of 453 NSCLC specimens were collected. Forty specimens with different levels of ALK fusion gene expression detected by IHC [ALK (-), (+), (2+), (3+), 10 specimens each] were randomly selected. FISH and qRT-PCR were employed to detect the expression levels of ALK fusion genes, and consistency analysis was conducted. ResultsWhen comparing the results of ALK fusion gene detection between IHC and FISH/qRT-PCR, the concordance rate for IHC ALK(-)/(3+) with FISH and qRT-PCR was 100%, demonstrating high consistency (r=0.781, r=0.740, P<0.05). The concordance rate between FISH and qRT-PCR was 97.5%, showing high consistency (r=0.943, P<0.05). ConclusionThere are variations in the results of ALK fusion gene detection among samples with different expression levels using FISH, qRT-PCR, and IHC methods, with IHC demonstrating higher sensitivity. FISH and qRT-PCR show high consistency in the detection of ALK fusion gene samples.
