What are the factors that determine the choice of treatment for recurrent disease?
The choice of subsequent treatment is based on multiple factors, including patient age, fitness status, the type of first-line treatment that was used, the quality and duration of response obtained with the first line of therapy, and individual patient characteristics. For the latter, the most important considerations are the presence or absence of unfavorable chromosomal abnormalities such as deletion 17p and/or 11q and whether the patient has developed resistance to treatment with purine analogs. It seems reasonable to offer the same or similar treatment plan to patients who have had a response with initial therapy that was longer than 2 to 3 years. Patients who have received initial therapy with single-agent alkylating agents, purine analogs, or a combination of these can achieve a significant benefit from treatment with CIT. Dmoszynska et al. 31 demonstrated that in patients with recurrent disease, the FCR combination is associated with a higher overall response rate (70% vs. 58%), higher complete response rate (24% vs. 13%), and a longer PFS (30.6 vs. 20.6 months) than the FC combination.

Allogeneic stem-cell transplantation (SCT) is the only curative treatment modality for patients with CLL.

The European Group for Blood and Marrow Transplantation released guidelines for consideration for SCT in patients with CLL, including younger patients, in 2007. 35 Patients who have fludarabine-refractory disease, patients with recurrent disease within 2 years of intensive treatment, and patients with P53 abnormalities requiring treatment should be considered candidates for SCT. Some of the high-risk features that warrant evaluation for SCT in younger patients with CLL are summarized in Table 4.
What is the complete response rate of fludarabine?
Treatment with single-agent purine nucleoside analogs such as fludarabine, pentostatin, or cladribine achieves complete response rates of 20% to 30%. Following these initial results, combination therapies such as FC were developed. Combining these two agents was based on in vitro data showing that fludarabine inhibits repair of cyclophosphamide-induced DNA inter-strand cross-links, suggesting the presence of complementary activity between the two. 11 The FC combination was studied in phase II clinical trials, 12 and was compared with single-agent fludarabine in phase III clinical trials. 13, 14 The FC combination was found to give a 35% complete response rate that was superior to that of single-agent fludarabine.
