This meta-analysis found that SRSF1 expression has limited diagnostic utility for grading glial tumors. Further prospective studies are needed to clarify its role, despite observed heterogeneity.

Area of Science:

  • Oncology
  • Molecular Biology
  • Pathology

Background:

  • Glial tumor grading relies on morphological and molecular features, with ongoing research for reliable markers.
  • SRSF1, a splicing factor, has been proposed as a potential marker for glial tumor grading.
  • Current consensus on effective markers for glial tumor grading remains elusive.

Purpose of the Study:

  • To evaluate the diagnostic utility of SRSF1 immunohistochemical expression in glioma grading.
  • To assess the correlation between SRSF1 expression levels and glioma grades.

Main Methods:

  • A meta-analysis was conducted following PRISMA guidelines from 2013-2023.
  • Statistical analysis included Q test, I2 statistics for heterogeneity, and meta-regression.
  • Publication bias was assessed using funnel plot and Egger's tests.

Main Results:

  • Four studies involving 193 articles were included in the meta-analysis.
  • Pooled sensitivity, specificity, and diagnostic odds ratio were 0.592, 0.565, and 1.852, respectively.
  • Area Under the Curve (AUC) was 0.558, indicating poor diagnostic accuracy; significant heterogeneity was noted.

Conclusions:

  • SRSF1 expression shows limited diagnostic utility for grading glial tumors.
  • Significant heterogeneity in pooled results underscores the need for high-quality, prospective studies.
  • Further research is required to establish definitive criteria for SRSF1's role in glioma grading.
