In one study, van der Wekken et al. “…found that Dichotomous ALK-IHC is superior to ALK-FISH on small biopsies and FNA to predict tumor response and survival to crizotinib for advanced NSCLC patients.” ⁷

ALK (D5F3) Assay and detection with amplification vs. FISH

Technical benefits of IHC testing

ALK FISH can present technical challenges in evaluating patient results and offers the potential for false negatives. Recent studies indicate that the ALK (D5F3) Assay stained with OptiView DAB Detection and Amplification (OptiView DAB Detection and Amp) is sensitive and specific for determination of ALK status, and a better alternative to ALK FISH. There are reports of ALK IHC-positive, FISH-negative patients benefitting from treatment with XALKORI, ZYKADIA or ALECENSA
