- Abstract
Background: Lung cancer is a major public health problem. It is the most common cause of cancer-related death in men and the second most common in women. Moreover, EML4-ALK (the echinoderm microtubule-associated protein like4-anaplastic lymphoma kinase fusion gene) has been identified as a potent oncogenic driver in non-small-cell lung carcinoma (NSCLC), in particular adenocarcinoma (ADC) and less commonly squamous cell carcinoma. The aim of current of study was to investigate ALK protein overexpression and its correlation with EML4-ALK gene rearrangement by CISH. Method: The paraffin embedded blocks were retrospectively collected from 80 patients diagnosed with NSCLC. ALK protein study was performed by using Monoclonal Mouse Anti-Human for IHC and for EML4-ALK fusion gene by using CISH (CISH working solution /Zytovision, Germany). Results: ALK protein overexpression was detected in (10%, n=8/80) of NSCLC and the ALK gene rearrangement was (7.5%, n= 6/80). There was high concordance in the assessment of ALK gene rearrangement by CISH techniques and ALK protein expression by IHC (P=0, r=0.94). Conclusion: IHC and CISH were very well correlated in detection of ALK protein expression and ALK gene rearrangement, respectively. Also, CISH is a new and highly practical method to detect EML4-ALK, therefore, it could be introduced in plans of ADC management and less commonly SCC of the lung.
