چکیده
BACKGROUND Few studies have investigated the prognostic factors for nasal natural killer (NK)/T-cell lymphoma. METHODS This was a retrospective multicenter clinical study. The clinical records of 36 patients with nasal NK/T-cell lymphoma who had been first treated between 1996 and 2011 were collected from 12 hospitals. RESULTS High serum levels of C-reactive protein (≥1.0 mg/dL), lactate dehydrogenase (≥350 IU/L), and soluble interleukin-2 receptor (sIL-2R; ≥600 U/mL) were associated with worse prognosis. A prognostic score was devised by totaling the number of these 3 predictors: 0 or 1 = score 0; and 2 or 3 = score 1. As for tumor invasion, local invasion beyond the nasal cavity was associated with poor prognosis, and a prognostic score was devised as: tumor restricted to nasal cavity, yes = score 0; no = score 1. A novel prognostic index (NPI) was established based on these scores from 0 to 2. Disease-specific survival rates at 5 years were: 90.0% for NPI = 0; 29.3% for NPI = 1; and 0.0% for NPI = 2. CONCLUSION Our NPI is valid for anticipating prognosis of nasal NK/T-cell lymphoma.

متن کاملClinical differences between nasal and extranasal natural killer/T-cell lymphoma: a study of 136 cases from the International Peripheral T-Cell Lymphoma Project.
Among 1153 new adult cases of peripheral/T-cell lymphoma from 1990-2002 at 22 centers in 13 countries, 136 cases (11.8%) of extranodal natural killer (NK)/T-cell lymphoma were identified (nasal 68%, extranasal 26%, aggressive/unclassifiable 6%). The disease frequency was higher in Asian than in Western countries and in Continental Asia than in Japan. There were no differences in age, sex, ethni...
متن کاملDecreased apolipoprotein A-I level indicates poor prognosis in extranodal natural killer/T-cell lymphoma, nasal type
BACKGROUND Extranodal natural killer (NK)/T-cell lymphoma, nasal type (ENKTL) is an invasive lymphoid malignancy with unfavorable survival, for which a prognostic model has not yet been validated. We hypothesized that serum apolipoprotein A-I (ApoA-I) may serve as a novel prognostic marker for ENKTL. PATIENTS AND METHODS A total of 236 newly diagnosed cases of ENKTL were analyzed retrospectiv...
متن کاملPrognostic factors for mature natural killer (NK) cell neoplasms: aggressive NK cell leukemia and extranodal NK cell lymphoma, nasal type.
BACKGROUND Patients with natural killer (NK) cell neoplasms, aggressive NK cell leukemia (ANKL) and extranodal NK cell lymphoma, nasal type (ENKL), have poor outcome. Both diseases show a spectrum and the boundary of them remains unclear. The purpose of this study is to draw a prognostic model of total NK cell neoplasms. PATIENTS AND METHODS We retrospectively analyzed 172 patients (22 with A...

The "sandwich" protocol, was first proposed by us and comprised of l-asparaginase, vincristine, and prednisone chemotherapy with radiotherapy, results in 2-year overall survival and progression-free survival rates that surpass traditional therapies for patients with newly diagnosed, stage IE-IIE, nasal type, extranodal natural killer/T-cell lymphoma. The results had been published by cancer. Th...
