Abstract

Background and Objectives Cervical lymph node enlargement is observed in various diseases, including malignant lymphoma (ML). Open biopsy of the enlarged lymph node is frequently required for diagnosis, especially when ML is suspected. Serum levels of soluble interleukin 2 receptor (sIL-2R) may be useful as a biomarker of ML. This study aimed to determine whether the measurement of serum sIL-2R levels might be useful to diagnose ML.

Materials and Methods We retrospectively reviewed the data of 281 patients who had undergone open cervical lymph node biopsy at our institution between 2015 and 2019, including 157 males and 124 females (age range, 5–90 years). Data on the patients' age, final diagnosis, and serum sIL-2R levels were obtained from their medical records.

Results Overall, 184 cases of MLs and 97 cases of other diseases (non-MLs [NMLs]) were recorded. The mean age was significantly higher and mean serum sIL-2R levels were significantly higher in the ML group than in the NML group. In the ML group, the serum sIL-2R levels were significantly higher in patients with T cell lymphoma than in those with B cell lymphoma. The area under the receiver operating characteristic curve of the serum sIL-2R level for predicting ML was 0.711, and a serum sIL-2R level of 1,246 U/mL was associated with the maximum value of the sensitivity + specificity for the diagnosis of ML. Multivariate analysis revealed that the area under the receiver operating characteristic curve increased to 0.758 for patients aged >61 years and patients with serum sIL-2R levels of >1,246 U/mL.

Conclusions Among patients presenting with cervical lymphadenopathy, the measurement of serum sIL-2R levels could be useful for distinguishing between patients with and without ML, with a cutoff level of 1,246 U/mL for the diagnosis of ML.
