Objectives: To assess the level of serum lactate dehydrogenase 2 (LD2) in patients with NHL with and without bone marrow infiltration. Place and Duration: In the Oncology department of Mayo Hospital, Lahore for one-year duration from September 2019 to September 2020. Introduction: Lactate dehydrogenase (LDH) is often elevated in patients with hematopoietic tumors and has been shown to be prognostic, especially in patients with non-Hodgkin's lymphoma (NHL). The level of the LD2 isoenzyme in the serum was determined in 60 already diagnosed patients with NHL. Aims and Objectives: The patients were divided into two groups, 30 patients with bone marrow infiltration (group B) and the rest without infiltration (group C). The values were compared with 20 healthy controls matched for age and sex (Group A). Estimates were made before starting chemotherapy. Results: LD2 level was significantly increased in NHL patients compared to the control group. There was also a significant difference when the values were compared between NHL patients with and without bone marrow infiltration. The levels showed a positive correlation with the extent of the disease. Conclusion: We conclude that the above-mentioned non-invasive parameter is a useful indicator of the severity of the disease.
