PURPOSE: Extranodal NK/T-cell lymphoma, nasal type (ENKL), is an Epstein-Barr virus (EBV)-associated lymphoma for which a new chemotherapeutic regimen called SMILE (steroid, methotrexate, ifosfamide, L-asparaginase and etoposide) recently showed promising results. Experimental design: The amount of EBV-DNA was prospectively measured in whole blood and plasma samples by real-time quantitative polymerase chain reaction from 26 patients registered in the SMILE phase II study.
RESULTS: Before treatment, the EBV-DNA was detected in 22 samples of whole blood with a median number of 3,691 copies/mL (range: 0-1.14 x 107), but 15 samples of plasma with a median of 867 copies/mL (range: 0-1.27 x 107). Results of these 2 measurements of EBV-DNA well correlated (R2 = 0.994, P less than 0.001). The overall response rate to SMILE was significantly higher in patients with less than 105 copies/mL of EBV-DNA in whole blood at enrollment (90% vs. 20%, P = 0.007), and in patients with less than 104 copies/mL of EBV-DNA in plasma (95% vs. 29%, P = 0.002). The incidence of grade 4 toxicity of SMILE other than leukopenia/neutropenia was significantly higher in patients with 105 copies/mL of EBV-DNA or more in whole blood (100% vs. 35%, P = 0.007) than that of others, and in patients with 104 copies/mL or more in plasma (86% vs. 26%, P = 0.002).
CONCLUSIONS: These findings suggest that whole blood is more sensitive for clinical use than plasma. The EBV-DNA amount in whole blood was useful for predicting tumor response, toxicity and prognosis after SMILE chemotherapy for ENKL.
