- Abstract
To evaluate the clinical significance of CD21S expression of diffuse large B-cell lymphoma (DLBCL) tumour cells, we compared their clinical features, immunophenotype, response to therapy and outcome in relation to CD21S expression. Between 1987 and 1999, frozen sections from 240 DLBCL cases were examined for CD21S expression by immunohistochemical methods. CD21S expression was detected on the tumour cells of 87 (36%) cases. The median age of the CD21S+ DLBCL cases was 65 years (range: 17–84 years), the male–female ratio was 42:45, and they showed the following clinical features: Eastern Cooperative Oncology Group score >1 in 14%, lactate dehydrogenase greater than normal levels in 38%, extranodal sites >1 in 14%, stages III/IV disease at diagnosis in 29%, B symptoms in 17%, and a high/high–intermediate International Prognostic Index (IPI) in 23%. They also showed a better overall survival ( P = 0·00001, log-rank test) and a better complete remission rate ( P = 0·00004, chi-square test) than CD21S− DLBCL. Moreover, CD21S+ DLBCL showed a better survival than CD21S− DLBCL for both low/low–intermediate and high/high–intermediate risk categories of IPI ( P = 0·045 and P = 0·0016 respectively). Multivariate analysis identified CD21S expression as an independent factor for survival when compared with the five IPI factors. These findings indicate that CD21S expression of DLBCL tumour cells is a useful prognostic factor for survival.
