Table 1.

Five-year relapse-free and overall survival rates according to the International Prognostic Index (IPI) and age-adjusted IPI (adapted from reference ¹).

Risk Group	Number of Adverse Factors*	5-Year Relapse-Free Survival (%)	5-Year Overall Survival (%)
* Adverse risk factors for IPI are: stage III or IV disease, age > 60 years, elevated lactate dehydrogenase (LDH), ECOG performance status ≥ 2, ≥ 2 extranodal sites
^# Adverse risk factors for age-adjusted IPI are: stage III or IV disease, elevated LDH, ECOG performance status ≥ 2
*International Prognostic Index*
Low	0 or 1	70	73
Low-intermediate	2	50	51
High-intermediate	3	49	43
High	4 or 5	40	26
*Age-adjusted International Prognostic Index*
Low	0	86	83
Low-intermediate	1	66	69
High-intermediate	2	53	46
High	3	58	32
