From the Guidelines
Lymphoma cases often present with elevated lactate dehydrogenase (LDH), lymphocytosis, and anemia, but high lactate levels, high monocytes, and macrocytic anemia are not typically characteristic laboratory abnormalities associated with lymphoma diagnosis. When evaluating laboratory abnormalities in lymphoma, common findings include anemia, leukopenia or leukocytosis, thrombocytopenia, hypercalcemia, elevated erythrocyte sedimentation rate (ESR), and abnormal liver function tests 1. Treatment options for lymphoma depend on the type, stage, and patient factors, with regimens such as ABVD for Hodgkin lymphoma, R-CHOP for diffuse large B-cell lymphoma, and rituximab alone or in combination with chemotherapy for follicular lymphoma 1. Key laboratory tests for monitoring lymphoma include complete blood counts, liver function tests, and lactate dehydrogenase (LDH) levels, with regular follow-up examinations of lymph nodes, liver, and spleen, as well as monitoring for autoimmune cytopenias 1. Some lymphoma subtypes, like chronic lymphocytic leukemia (CLL), may have specific treatment options, including fludarabine, cladribine, or monoclonal antibodies like alemtuzumab, with allogeneic progenitor cell transplantation considered for high-risk or refractory disease 1. In terms of specific laboratory abnormalities, lymphoma can present with a range of findings, but elevated LDH, anemia, and lymphocytosis are more commonly associated with lymphoma than high lactate levels, high monocytes, or macrocytic anemia. Regular monitoring and follow-up are crucial in managing lymphoma, with a focus on detecting relapse or progression, as well as managing treatment-related side effects 1. Overall, the management of lymphoma requires a comprehensive approach, incorporating laboratory testing, imaging studies, and individualized treatment planning.

From the Research
Laboratory Abnormalities in Lymphoma
- Elevated lactate levels: Studies have shown that patients with lymphoma can have elevated serum lactate levels, which can be used to differentiate between sepsis and progressive lymphoma 2.
- Lymphocytosis: Some types of lymphoma, such as angioimmunoblastic T-cell lymphoma, can present with lymphocytosis, although lymphopenia is also common 3.
- High monocytes: Absolute monocyte count (AMC) has been proposed as a prognostic factor in patients with follicular lymphoma, with higher AMC associated with shorter overall survival (OS) and progression-free survival (PFS) 4.
- Macrocytic anemia: Macrocytosis is a relatively common finding in adult patients, and some studies suggest that it can be associated with lymphoma, particularly in patients with unexplained macrocytosis 5.
Treatment Options and Prognosis
- The prognosis of lymphoma patients can be affected by various factors, including lactate levels, absolute lymphocyte count (ALC), AMC, and the lymphocyte to monocyte ratio (LMR) 2, 4.
- Elevated lactate dehydrogenase (LDH) levels have been associated with inferior overall survival (OS) in patients with lymphoma 2.
- ALC, AMC, and LMR at diagnosis can predict clinical outcomes in follicular lymphoma, with lower ALC, higher AMC, and lower LMR associated with shorter OS and PFS 4.
- The combination of lactate-targeted therapy and classical immunotherapy may be a promising development direction in the future for the treatment of lymphoma 6.
