ABSTRACT
OBJECTIVE:
To investigate the clinical features and prognostic factors of patients with extranodal NK/T cell lymphoma (ENKTL).METHODS:
The clinical data of patients with ENKTL from November 2009 to November 2019 was collected and retrospectively analyzed to clarify the clinical features of ENKTL, and evaluate the factors that affected survival and prognosis.RESULTS:
Forty-seven patients with ENKTL were collected, median age was 40 (12-82) years old, and more common in males than females, at the ratio of 1.47ⶠ1. The median follow-up was 28 (1-112) months, and 5-year overall survival (OS) rate was 49.3%. The 5-year OS rates of the subjects with ECOG performance stage 0-1 and ≥2 were 51.6% and 0 (P=0.001), respectively. The 5-year OS rates of International Prognostic Index (IPI) score 0-1 and ≥2 were 60.0% and 40.6% (P=0.027), respectively. The 5-year OS rates of Ann Arbor staging â /â ¡ and stage â ¢/â £ were 61.3% and 31.7% (P=0.005), respectively. The 5-year OS rates of the patients with presentation of B symptoms and without presentation of B symptoms were 79.0% and 30.1% (P=0.013), respectively. The 5-year OS rates of plasma EBV-DNA level < 5×102/ml and ≥ 5×102/ml were 60.4% and 33.3% (P=0.003), respectively. The 5-year OS rates of the patients receiving chemotherapy alone, combined chemotherapy and radiotherapy, and chemotherapy followed by autologous hematopoietic stem cell transplantation (auto-HSCT) were 12.9%, 86.5%, and 62.5% (P=0.001), respectively. Univariate analysis showed that ECOG score, IPI score, Ann Arbor staging, B symptoms, the copy number of EBV-DNA, and treatment regimens were statistically significant for OS. Multivariate analysis showed that ECOG score, B symptoms, the copy number of EBV-DNA, and treatment regimens were independent factors of ENKTL OS.CONCLUSION:
ECOG score, B symptoms, the copy number of EBV-DNA, and treatment regimens are independent prognostic factors for OS of patients with ENKTL.
