IPI provide survival predictions at diagnosis, but not known whether retain prognostic value for patients completed initial treatment and in remission.
Investigators studied conditional survival (CS), to describe outcomes in patients who surviveda pre-specified time since diagnosis.
For SLL patients with advanced stage had continuously worse CS.
For SLL/CLL, the CS in black patients persistently worse compared to other racial groups.
Age, race and stage continue to affect disease-related mortality in indolent NHL.
In black patients favorable survival with MCL and persistently poorer outcomes in SLL/CLL suggest biological differences.
