Objective This study aimed to compare the clinical characteristics and prognoses of primary Waldeyer′s ring diffuse large B-cell lymphoma (DLBCL) and extranodal nasal-type NK/T-cell lymphoma (ENKTCL). Methods From 2000 to 2008, 122 patients with primary Waldeyer′s ring DLBCL and 44 patients with primary Waldeyer′s ring ENKTCL consecutively diagnosed were retrospectively compared. Patients with DLBCL usually received 4－6 cycles of CHOP-based chemotherapy followed by involved-field radiotherapy. Patients with early stage ENKTCL usually received extended-field radiotherapy with or without subsequent chemotherapy, or short courses (1－3 cycles) of chemotherapy followed by radiotherapy. Kaplan-Meier method was used for survival analysis. Logrank method was used for univariate analysis. Results The follow-up rate was 82%. The number of patients followed 5 years were 32 and 15 in DLBCL and ENKTCL. DLBCL mainly presented with stage Ⅱ tonsillar disease with regional lymph nodeinvolvement. ENKTCL occurred predominately in young males, as nasopharyngeal stageⅠ disease with B symptoms and involving adjacent structures. The 5-year overall survival (OS) and progression-free survival(PFS) rates were 74% and 67% in DLBCL, and 68% and 59% in ENKTCL (χ2=0.53,1.06,P=0.468,0.303), respectively. In stage Ⅰ and Ⅱ diseases, the 5-year OS and PFS rates were 79% and 76% forDLBCL compared to 72% and 62% for ENKTCL (χ2=1.20,2.46,P=0.273,0.117). On univariate analysis, age>60 years, elevated lactate dehydrogenase, eastern cooperative oncology group performance status>1, international prognosis index (IPI) score ≥1, stage Ⅲ/IV diseases and bulky disease were associated with unfavorable survival for DLBCL (χ2=9.40,12.72,6.15,10.36,12.48,5.53,P=0.002,0.000,0.013,0.001,0.000,0.019), and only age>60 years and IPI score ≥1 were associated with poor survival for ENKTCL (χ2=3.98,8.41,P=0.046,0.004). Conclusions These results indicate that remarkable clinical disparities exist between DLBCL and ENKTCL in Waldeyer′s ring. Different treatment strategies for each can result in similarly favorable prognoses.
