Background: Serum YKL-40 levels are increased in various inflammatory disorders and a wide range of malignancies. Moreover, these elevated levels correlate with poor prognosis of cancer patients, suggestive of YKL-40 might be a prognostic biomarker. The impact of YKL-40on non-Hodgkin lymphoma prognosis has not been fully explained. Aim: To study the serum levels and lymph node tissue expression of YKL-40 in diffuse large B-cell lymphoma (DLBCL) patients to assess its prognostic value and shed light on its impact on survival. Methods: The study included 60 DLBCL patients. ELISA was used to assess the serum YKL-40 levels. Immuno-histochemical staining was used to detect YKL-40 protein expression in lymphoma specimens. Results: YKL-40 serum levels were significantly higher in DLBCL patients when compared with the control group. YKL-40 was expressed in tumor tissue in 66.67% of patients. Receiver�operator curve analysis showed serum YKL-40 at a cut-off value of � 95.5 (ng/mL) had a sensitivity of 70% and a specificity of 95% for DLBCL diagnosis. In DLBCL, Progression free and overall survival rates significantly decrease in patients with increased serum levels of YKL-40 above the cut off level and YKL- 40 positive expressed patients. Conclusions: Serum YKL-40 and its tissue expression could be a valuable prognostic marker in DLBCL patients.
