Strokes with concomitant malignancy are associated with nonspecific biomarkers such as elevated D-dimer, elevated CRP, elevated fibrinogen, elevated lactate dehydrogenase, low Hb, undetermined stroke etiology (especially ESUS), and multiterritorial infarcts in brain imaging (3, 4, 18, 28). This evidence concerns the gene GSTM1 and stroke disorder.
