Abstract:
OBJECTIVETo investigate the roles of different clinicopathological features and expression of EBV genome in prognosis of intestinal T-cell lymphoma (ITCL).
METHODSPolymerase chain reaction for TCR-gamma gene rearrangement, in situ hybridization for EBER1/2 and immunohistochemical staining for CD4, CD8, CD45RO, CD56, TIA-1 were investigated and all patients followed-up. The LMP-1 expression was determined in forty-two ITCLs cases. The relationship between clinical data, different clinicopathological features, expression of EBV genome and prognosis were analyzed by SPSS10.0 program.
RESULTS(1) All 42 cases of ITCL had an extremely poor prognosis with a median survival of 3.0 months, of which the one year survival rate and two year survival rate being 30% and 22% respectively. (2) The patients without TCR-gamma gene rearrangements showed poorer prognosis than those with TCR-gamma gene rearrangements, and the patients who received operation and chemotherapy showed better prognosis than those who only received operation (P < 0.05). (3) No significant prognostic factor for ITCLs was determined.
CONCLUSIONThe special clinicopathological features of ITCL could be due to the cytotoxic function and the role of EBV infection in the pathogenesis of ITCL.
