Li Y, et al. - Researchers used data from the Surveillance, Epidemiology, and End Results Program database, to investigate the differences in incidence and survival of advanced Hodgkin lymphoma (aHL) according to four patient variables in recent decades. They paid attention to the outcomes of treatment of aHL and the advancement of public health care. They investigated prognosis indicators for aHL by performing relative survival, Kaplan-Meier, and Cox proportional hazards regression analyses. In each decade, an increased long-term survival rate was observed for patients with aHL, whereas findings showed narrowing of variations in survival rate according to sex, race, and socioeconomic status, except for older patients aged >60 years and the high-poverty group.
