Abstract

PURPOSE:

On the basis of the benefits of frontline radiation in early-stage, extranodal, natural killer (NK)/T-cell lymphoma (ENKTL), we conducted a phase II trial of concurrent chemoradiotherapy (CCRT) followed by three cycles of etoposide, ifosfamide, cisplatin, and dexamethasone (VIPD).

PATIENTS AND METHODS:

Thirty patients with newly diagnosed, stages IE to IIE, nasal ENKTL received CCRT (ie radiation 40 to 52.8 Gy and cisplatin 30 mg/m(2) weekly). Three cycles of VIPD (etoposide 100 mg/m(2) days 1 through 3, ifosfamide 1,200 mg/m(2) days 1 through 3, cisplatin 33 mg/m(2) days 1 through 3, and dexamethasone 40 mg days 1 through 4) were scheduled after CCRT.

RESULTS:

All patients completed CCRT, which resulted in 100% response that included 22 complete responses (CRs) and eight partial responses (PRs). The CR rate after CCRT was 73.3% (ie, 22 of 30 responses; 95% CI, 57.46 to 89.13). Twenty-six of 30 patients completed the planned three cycles of VIPD, whereas four patients did not because they withdrew (n = 2) or because they had an infection (n = 2). The overall response rate and the CR rate were 83.3% (ie; 25 of 30 responses; 95% CI, 65.28 to 94.36) and 80.0% (ie, 24 of 30 responses; 95% CI, 65.69 to 94.31), respectively. Only one patient experienced grade 3 toxicity during CCRT (nausea), whereas 12 of 29 patients experienced grade 4 neutropenia. The estimated 3-year, progression-free and overall survival rates were 85.19% (95% CI, 72.48 to 97.90) and 86.28% (95% CI, 73.97 to 98.59), respectively.

CONCLUSION:

Patients with newly diagnosed, stages IE to IIE, nasal ENKTL are best treated with frontline CCRT.
