Adenocarcinomas with prevalent (⩾70%) bronchiolo-alveolar component were less commonly (two out of seven cases) immunoreactive for fascin (Figure 2, H, I) than those with prevalent invasive components of acinar (18 out of 23) papillary (24 out of 31), or solid (28 out of 31) types (χ2=19.44, P=0.005) (Figure 2, F, G). Here, FSCN1 is linked to adenocarcinoma.
