Insights
Enlargement of abdominal nodes is rare in hairy cell leukemia (HCL) but can indicate advanced disease or transformation. Early CT scans are recommended for diagnosis and monitoring of retroperitoneal lymphadenopathy.
Area of Science:
- Hematology
- Oncology
Background:
- Hairy cell leukemia (HCL) is a rare chronic B-cell leukemia.
- Lymphadenopathy is not a common initial finding in HCL.
Observation:
- Enlargement of retroperitoneal lymph nodes was observed in two HCL patients.
- One patient showed node reduction after irradiation; the other had pancytopenia preventing treatment.
- Alpha-interferon treatment failed in one patient with severe pancytopenia.
Findings:
- Lymph node enlargement, particularly retroperitoneal, is infrequent at initial HCL diagnosis.
- Significant lymphadenopathy was present in 60% of patients in the final disease stage.
- The clinical significance of marked abdominal lymphadenopathy requires further investigation.
Implications:
- Computed tomography (CT) is recommended for initial and follow-up assessment of abdominal lymph nodes in HCL.
- Early detection of lymphadenopathy may aid in identifying disease progression or transformation.
- Further research is needed to understand the prognostic value of abdominal lymphadenopathy in HCL.
Abstract:
Enlargement of nodes in leukaemia with hairy cells (LVB) during the initial examination is rarely encountered. In the final stage of the disease it was found in six of our ten patients. A special situation is marked enlargement of retroperitoneal nodes observed in two patients. In one of them the nodes diminished after irradiation, in the second patient irradiation was not possible because of severe pancytopenia. Treatment with alpha-interferon failed previously in this patient. The question remains whether marked enlargement of the abdominal nodes is part of the picture of the disease or whether it is the manifestation of transformation of the disease into a more acute type. The authors recommend examination of the abdominal nodes by means of computed tomography (CT) already during the initial examination and during the subsequent course of the disease, in particular when there are signs of relapse.
