This study examined small gliomas (less than 2 cm). While many are benign and removable, some early-stage gliomas show aggressive traits, leading to poor outcomes.

Area of Science:

  • Neuro-oncology
  • Pathology

Background:

  • Small gliomas, defined as less than 2 cm in diameter, present unique diagnostic challenges.
  • Understanding the early clinicopathological features of these tumors is crucial for effective management.

Purpose of the Study:

  • To investigate the clinicopathological characteristics of small gliomas.
  • To correlate histological findings with proliferative activity in small gliomas.

Main Methods:

  • Analysis of nine patients with gliomas < 2 cm.
  • Examination of tumor histology, Daumas-Duport grading, bromodeoxyuridine labeling index, and proliferating cell nuclear antigen (PCNA) counts.

Main Results:

  • Tumor locations included white matter (3) and corticomedullary junction (6).

  • Histological diagnosis, grading, and proliferation markers showed good correlation.
  • Most small gliomas were histologically benign, localized, and surgically removable if in non-eloquent brain areas.

    • Conclusions:

    • Small gliomas exhibit variable behavior, with some presenting as high-grade and invasive early on.
    • Early detection and accurate characterization are vital, as some small gliomas can have poor prognoses despite their size.
