Sequential P-GEMOX and radiotherapy for early-stage extranodal natural killer/T-cell lymphoma: A multicenter study.

For the KPI model, distinction in survival outcomes was observed between groups, but the severity of the prognostic risk was not consistent with the grading of the index stratification: group two had an obvious trend for longer PFS than group one ( p = 0.129), and no statistical survival differences were detected between group one and group four (PFS, p = 0.389; OS, p = 0.271) (Figure 2C,D ).

Besides, the other three unfavorable risk factors (age >60 years, stage II and elevated LDH) also showed a trend for the distinction of survival.
