Summary
Meningeal leukemia, a rare complication of chronic lymphocytic leukemia (CLL), can be effectively treated with intrathecal chemotherapy. Patients can achieve long-term remission, demonstrating the efficacy of this therapy for CNS involvement in CLL.
Area of Science:
- Hematology
- Neuro-oncology
- Oncology
Background:
- Chronic lymphocytic leukemia (CLL) is a common B-cell malignancy.
- Meningeal leukemia, while uncommon, represents a serious complication of CLL.
- Central nervous system (CNS) involvement in CLL requires specific therapeutic approaches.
Observation:
- Two patients with classic CLL presented with meningeal leukemia.
- Meningeal involvement occurred as a complication of their underlying hematologic malignancy.
- Clinical signs and symptoms of CNS leukemia were present at diagnosis.
Findings:
- Intrathecal chemotherapy was administered to both patients.
- The chemotherapy regimen successfully eradicated the signs and symptoms of meningeal involvement.
- One patient remained alive with no evidence of CNS leukemia 30 months post-meningeal diagnosis and 5.5 years post-CLL diagnosis.
Implications:
- Meningeal leukemia in CLL, though infrequent, is a recognized clinical entity.
- Conventional intrathecal chemotherapy is an effective treatment for meningeal leukemia in CLL.
- Early diagnosis and treatment can lead to favorable long-term outcomes for patients with CNS involvement in CLL.
