“…In these studies a high complete response rate is associated with improved survival. The toxicity of these regimens is, however, considerable and a significant number of elderly patients may not complete the required number of chemotherapy courses (Connors, 1988), due to a poor performance status and/or considerable therapy-related morbidity (Anderson et al, 1982;Goh & Williams, 1983;Armitage & Potter, 1984;Mead et al, 1984;O'Connell et al, 1986). Several studies have found a poorer prognosis of unfavourable NHL in elderly patients when compared to their younger counterparts (Jagannath et al, 1985;Solal-Celigny et al, 1987;Fisher et al, 1987;Dixon et al, 1986).…”
