Abstract:
OBJECTIVETo investigate the clinical significance of peripheral blood regulatory T cell (Treg) population in patients with extranodal NK/T cell lymphoma, nasal type (ENKL).
METHODSThe peripheral blood CD4+CD25+ Treg cell population was detected by flow cytometry in 41 newly diagnosed ENKL patients between March 2009 and December 2012.
RESULTSThe proportion of CD4+CD25+ Treg cell population increased in ENKL patients compared to healthy donors [(9.64±4.96)% vs(7.31±3.02)%, P<0.05], and decreased significantly after treatment [(5.18±2.19)%, P<0.01]. Patients when got response had significantly lower proportion of Treg cells [(8.79±4.15)%] as compared with those without response [(14.57±6.73)%, P<0.05]. The proportion of Treg population was positively related to the serum lactate dehydrogenass level.
CONCLUSIONThe proportion of peripheral blood Treg cells may be helpful for predicting prognosis and therapeutic efficacy in ENKL patients.
