BACKGROUND:Promyelocytic leukemia (PML) tumor suppressor gene plays a key role in acute PML pathogenesis but its involvement in pathogenesis and prognosis of solid cancers has not been defined yet.PATIENTS AND METHODS:In all, 62 ampullary adenocarcinoma patients who underwent curative surgery between 1996 and 2005 were included. Expression analysis of PML was carried out by immunohistochemical staining and correlated with disease-free survival (DFS) and overall survival (OS).RESULTS:In 24 tumor specimens (38.7%), PML was classified as absent, in 16 (25.8%) as focally expressed and in 22 (35.5%) as diffusely expressed. By univariate analysis, DFS was significantly influenced by pathological T stage (P=0.03), lymph nodal involvement (P=0.002), and PML expression (P=0.001). DFS in patients without PML expression was 28.0 months versus 45.1 and 75.5 for patients with focal and diffuse expression, respectively. OS in the group of patients without PML expression, with focal expression, and with diffuse expression was 40, 48, and 77 months, respectively (P=0.002). By a multivariate analysis, PML expression was the strongest prognostic factor for DFS (P=0.003) and the only statically significant prognostic factor for OS (P=0.009).CONCLUSIONS: Our preliminary data suggest PML as a novel prognostic tool for ampullary cancer patients.
