In 44 patients with end-stage renal disease, 24 on hemodialysis and 20
on CAPD, the survival was calculated using the life table method. Med
ian survival for CAPD was 19 months and for hemodialysis 47 months. Us
ing Cox's proportional hazards model, treatment modality and performan
ce score were significant determinants of survival. Performance score
was influenced by age and kidney disease. When survival was analyzed s
eparately for patients with a good or a bad performance score, the sur
vival was better in the hemodialysis group only in patients with a bad
score (ECOG 3 and 4). Patients with a good score had similar prognose
s, irrespective of treatment modality.
