PURPOSE: A phase II trial was conducted to evaluate the therapeutic efficacy and safety profiles of frontline concurrent chemoradiotherapy (CCRT) plus consolidation chemotherapy for patients with stage I/II nasal natural killer/T-cell lymphoma (NKTCL). PATIENTS AND METHODS: Patients with newly diagnosed, measurable stage I/II nasal NKTCL were eligible. The CCRT included two cycles of the DEP regimen (dexamethasone, etoposide, and cisplatin) every 4 wk with concurrent 5040 cGy radiation in 28 fractions for 5 wk. Patients without disease progression after CCRT were subjected to two cycles of DVIP consisted of dexamethasone, etoposide, ifosphamide, mesna, and cisplatin every 4 wk. The primary endpoint was tumor response rate, and secondary endpoints were survival and toxicities. This phase II study has been registered in the ClinicalTrials.gov (NCT00292695). RESULTS: Thirty-three patients received CCRT, and 29 patients received two cycles of consolidation DVIP after CCRT. Among the 32 evaluable patients, 20 achieved complete response and 6 achieved partial response. The overall and complete response rate was 81% (95% CI, 68-95%) and 63% (95% CI, 46-79%), respectively. The 2-yr and 5-yr progression-free survival rate for intention-to-treat population was 64% (95% CI, 47-80%) and 60% (95% CI, 39-73%), respectively; while the corresponding overall survival rate was 73% (95% CI, 57-88%) and 66% (95% CI, 50-83%), respectively. The most common treatment-related grade 3/4 adverse event was leukopenia (85%). CONCLUSION: Frontline CCRT plus consolidation chemotherapy is feasible and effective for treating localized nasal NKTCL.
