PURPOSE: Fludarabine phosphate is effective as a single agent in
low-grade non-Hodgkin's lymphoma (NHL). Combined with other
antineoplastic agents it enhances the antitumor effect. Our aim was to
define the therapeutic efficacy and toxicity of a combination of
fludarabine, cyclophosphamide and dexamethasone (FluCyD) in patients
with advanced low-grade lymphoma. PATIENTS AND METHODS: Twenty-five
adults with pretreated advanced-stage low-grade NHL were treated with
three-day courses of fludarabine 25 mg/m2/day, cyclophosphamide 350
mg/m2/day, and dexamethasone 20 mg/day, every four weeks for a maximum
of six courses. RESULTS: Of the 25 patients, 18 (72%) responded, 8 (32%)
achieving CR and 10 (40%) PR. Seven were failures. The median follow-up
was 21 months (5-26). Eight CR patients remain in CR after 5-21 months.
Of 10 PR patients, 3 are in continuous PR without further treatment
after 12, 17 and 18 months. Myelosuppression was the most prevalent
toxic effect. Although severe granulocytopenia (granulocyte count nadir
< 500/microliter) and thrombocytopenia (platelet count nadir <
50,000/microliter) occurred in only 10% and 16% of courses,
respectively, slow granulocyte or platelet count recovery caused delay
of 40% of the courses. Nine patients (36%) required discontinuation of
therapy because of persistent granulocytopenia and/or thrombocytopenia:
three after one course, three after 2-4 courses, and three after five
courses. Thirteen infectious episodes in 11 patients complicated 11% of
courses. Two of 10 patients monitored for the circulating EBV load
showed increased viral load. One of these developed aggressive lymphoma.
CD4+ lymphocytes declined from a pre-therapy median value of
425/microliter to 141/microliter post-treatment (P = 0.001).
Non-hematologic toxicities were rare and mild. CONCLUSIONS: The
combination of fludarabine with cyclophosphamide and dexamethasone is
effective in pretreated advanced-stage low-grade NHL. It may broaden the
range of therapeutic options in the salvage treatment of these patients.
The main toxicity of this combination is prolonged myelosuppression that
may cause treatment delay or withdrawal. The benefit of adding
granulocyte colony-stimulating factor, particularly in patients with
poor marrow reserve, needs to be investigated.
