Prognostic relevance of thymidine kinase isozymes in adult non- Hodgkin's
lymphoma
PH Ellims, T Eng Gan, G Medley and MB Van Der Weyden
To determine whether kinase (TK) isozyme status adds clinically useful
information in adult non-Hodgkin's lymphoma (NHL), we have analyzed
peripheral blood plasma and lymphocytes of 44 patients with NHL for either
TK1 or TK2 isozyme activity. On the basis of isozyme status, patients could
be divided into two groups that did not differ significantly with respect
to known determinants for survival. The median survival of patients
exhibiting peripheral blood TK1 thymidine kinase activity was 40 wk and
that of individuals with TK2 activity was in excess of 200 wk. These data
suggest that peripheral blood TK1 isozyme is a useful independent
biochemical marker for a subgroup of NHL who respond poorly to current
therapy and thus require new therapeutic approaches.
