Abstract:
The clinical characteristics and prognosis remain unclear for nasal-type NK/T-cell lymphoma of Waldeyer ring (WR-NKTL). The aim of this study is to determine the clinical features and outcome. Ninety-one patients with WR-NKTL were reviewed. According to the Ann Arbor system, 15, 56, 12, and 8 patients had stage I, II, III, and IV. Of patients with stage I and II, 54 received combined chemotherapy and radiotherapy (CMT), 13 received radiotherapy alone, and 4 patients received chemotherapy alone. All 20 patients with stage III/IV received primary chemotherapy. The disease is characterized by predominance in young males, good performance, a propensity for nodal involvement, frequent stage II through IV diseases, low frequency of elevated LDH, low-risk international prognostic index (IPI), high sensitivity to radiotherapy, and intermediate sensitivity to chemotherapy. The 5-year overall survival and progression-free survival for all patients were 65% and 51%, respectively. The age, B symptoms, stage, and IPI were important prognostic factors. CMT tended to improve the survival compared with radiotherapy alone for patients with stage I and II diseases. Both nodal involvement and distant extranodal dissemination were the primary failure patterns. WR-NKTL appears to have distinct clinical characteristics and favorable outcomes.
