Περίληψη:
In the present study we report our results on the efficacy of
Fludarabine monophosphate in 20 B-chronic lymphocytic leukemia (CLL)
patients, refractory to conventional chemotherapy. Of the 20 patients 14
were males and 6 females with a median age of 58 years (44-70). Eight
had Binet stage B and 12 stage C. They were previously treated with
chlorambucil, prednisone, mini-CHOP or irradiation. Their disease
duration prior to fludarabine administration was 49 months (7-180).
Fludarabine was given at a dose of 25mg/m(2) daily, for five consecutive
days, monthly for six months and if responding for six additional
months. Treatment was administered on an outpatient basis. Complete
response (CR) was observed in 7 patients (33%) and partial remission
(PR) in 5 (25%). Of the complete responders 5 were males and 2 females
with a median age of 60 years (range 55-68); three of them had stage B
and 4 stage C disease; the median number of fludarabine courses for
achieving CR was 3 (range 2-5). In all CR patients a residual monoclonal
CD5/CD19 positive lymphocyte population was found in the peripheral
blood. All CRs relapsed shortly after discontinuation of therapy within
12 months. The main toxicity observed was upper respiratory tract and/or
pulmonary infections in 8 patients, requiring hospitalization. Among the
CRs one patient died during the administration of the third course of
therapy, due to a severe hypersensitivity reaction with Stevens-Johnson
syndrome. The importance of maintenance therapy is also stressed as PR
was sustained in some patients using 3 day cycles every 2-4 months. One
patient was maintained in this fashion for 60 + months.
This study showed that fludarabine is effective in CLL patients
refractory to conventional chemotherapy thus it may be given as the
treatment of choice if such patients still require treatment.
