Foamy cell mesothelioma

on cytoplasmic ⁄ nuclear b-ct expression support also the hypothesis that activation of the Wnt ⁄ b-ct signalling pathway occurs in a subset of gastric carcinomas. Finally, we observed a significant association between cytoplasmic ⁄ nuclear over-expression of b-ct and mixed carcinoma histotype, which we had previously shown to carry a guarded prognosis. It would be interesting to know whether or not the same applies to the series of Grabsch et al.
