Circulating U2 small nuclear RNA fragments as a novel diagnostic biomarker for primary central nervous system lymphoma.

ABSTRACT:

Background

Primary central nervous system lymphomas (PCNSLs) are highly aggressive tumors. Chemotherapy has improved prognosis significantly; however, early diagnosis is crucial for effective treatment. Presently, the diagnosis of PCNSL depends on histopathology of tumor biopsies. We have previously demonstrated differential expression of microRNAs in cerebrospinal fluid (CSF) samples from patients with PCNSL. Based on promising findings about circulating U2 small nuclear RNA fragments (RNU2-1f) as novel blood-based biomarkers for pancreatic, colorectal, and lung cancer, we investigated RNU2-1f in the CSF of PCNSL patients.

Methods

CSF was collected from patients with PCNSL (n = 72) and control patients with various neurologic disorders (n = 47). Sequential CSF samples were
