PTCL-U: peripheral T-cell lymphoma-unspecified, NK/T: extranodal natural killer/T-cell lymphoma, ALCL: anaplastic large cell lymphoma, ECOG: Eastern Cooperative Oncology Group, LDH: lactate dehydrogenase, -MG: serum microglobulin, IPI: International Prognostic Index, HR: hazard ratio, and 95% CI: 95% confidence interval. B-symptoms include unexplained fever over 38°C (100.4°F) for 1-2 weeks, unintentional weight loss of >10% of normal body weight over a period of 6 months or less, and drenching sweats, especially at night. IPI scores were calculated by summing the number of risk factors (age > 60 years, stage III/IV, involved extranodal sites > 1, ECOG performance status > 1, and elevated LDH levels).
