Expression of p300 and CBP is associated with poor prognosis in small cell lung cancer.
PurposeTo investigate the correlation among p300, CBP and MLL expression and the clinicopathological characteristics in resected SCLC patients.MethodsTwo hundred and twenty-two resected SCLC patients were included in this study. We evaluated p300, CBP and MLL expression by immunohistochemistry.ResultsPatients with high p300 expression had shorter OS and DFS than those with low p300 expression (p = 0.01; p = 0.009, respectively). The patients with CBP-positive tumors had significantly lower OS and DFS than those with CBP-negative tumors (p = 0.005 and p = 0.007, respectively). Moreover, the p300- and CBP-positive (+) group had a significantly poor OS and DFS. The multivariate Cox regression analysis showed that high p300 and CBP expression are independent markers of poor overall survival (p = 0.006; p = 0.017, respectively) in operable SCLC patients.ConclusionsHigh p300 and CBP expression are independent prognostic markers of poor overall survival for resected SCLC patients. The combination of p300 and CBP expression may be useful in identifying patients with increased risks of cancer recurrence of SCLC.
