Unlike the studies described above reporting the expression of A-FABP protein by immunohistochemical or two-dimensional electrophoresis analyses, we show on a long-term follow-up of patients that high expression of A-FABP was associated with a good prognosis and that the decrease of A-FABP expression is a tumor progression marker of pTa and pTa/pT1 group. The gene discussed is FABP4; the disease is neoplasm.
