Abstract:
Objective To investigate the clinicopathological and prognosis features of enteropathy-associated T-cell lymphoma (EATL).Methods 21 cases of EATL,6 cases of peripheral T-cell lymphoma (PTCL) and 11 cases of natural-killer/T-cell lymphoma (NKTCL) were collected from January 2008 to May 2015.The immunophenotype of the tumor cell was tested by EnVision and as well as EBV-EBER for EB virus.Some patients were performed with follow-up data.Results 21 EATL patients included 14 males,7 females and the middle age was 55 years old (40-79 years old).15 patients affected the small bowel,4 cases affected colon,2 cases affected more than one site.18 cases were mono-morpholohic EATL while 3 cases were classical EATL.The expression rates of neoplastic cells for CD3ε,CD4,CD8,CD56,Granzyme B,TIA-1 were 95.24 ％ (20/21),20.00 ％ (3/15),73.68 ％ (14/19),85.71％ (18/21),64.71％ (11/17),88.89 ％ (16/18) respectively.The expression of EBER in EATL patients (0,0/21) was obviously lower than that in NKTCL patients (100 ％,11/11).17 EATL patients had follow-up data,and the middle survival time was 15 months.No different prognosis was found in the three kinds of T-NHL (P =0.697).Conclusions EATL usually occurs in elder male and jejunum.The diagnosis of EATL needs a lot of information,including clinical history,endoscopy,histomorphology,immunophenotype and EBV-EBER result.EATL has low mobidity and high malignancy,it still lacks impactful therapeutic regimen.
