- Abstract:
- CLL is a chronic lymphoproliferative disorder which is characterized by the proliferation of a CD5 positive B cell clone. At diagnosis most patients are in early stage of the disease (stage A). It is well established that an early treatment in stage A is not associated with a survival advantage. Therefore, the disease should be treated only when signs of progression are present. The standard initial therapy is chlorambucil +/- prednisone. By this treatment remissions (mostly partial remissions) are achieved in about half of the patients. Fludarabine, a purine analogue, is more effective than chlorambucil as initial treatment (75% remissions, 27% complete remissions, 33 months progression free survival). However, the overall survival is not prolonged when compared to chlorambucil treatment. Fludarabine has a high efficacy in patients with recurrent disease, in particular in those who are resistant to alkylating agents. The allogeneic and autologous stem cell transplantation is an experimental treatment which may be indicated in younger patients who show a response to conventional treatment. With both procedures hematological remissions are frequently achieved and in some of the patients long lasting molecular remissions were obtained. Currently, it is unknown whether patients can be cured by stem cell transplantation and longer follow-up will be necessary to clarify this question. Monoclonal B-cell antibodies are effective in vivo and partial remissions can be obtained in chemotherapy refractory patients. Antibodies have a high efficacy in clearing lymphoma cells from peripheral blood and bone marrow but are less effective on the organomegaly.
