This study analyzed malignant uveal tumors over 15 years, revealing that high mitotic activity, necrosis, and specific vascular patterns predict severe progression. Epithelioid and mixed cell types correlate with worse outcomes in uveal melanoma.

Area of Science:

  • Ophthalmology
  • Oncology
  • Pathology

Context:

  • Retrospective analysis of 15 years of uveal malignant tumor cases at the Ophthalmological Clinic of Craiova.
  • Diagnosis confirmed through clinical, paraclinical (MRI, CT, Echo), and histological examinations.
  • A 4-year follow-up period was established for all investigated cases.

Purpose:

  • To conduct a clinicopathological study of uveal malignant tumors.
  • To identify histological features associated with tumor progression and metastasis.
  • To correlate specific cellular and vascular patterns with disease severity.

Summary:

  • Investigated parameters included tumor cytology, pigmentation, intravascular emboli, scleral infiltration, vascular invasion, vascular patterns, necrosis, and mitotic activity.

  • Histological indicators of aggressive tumor progression identified: high mitotic activity, extensive intratumoral necrosis, and infiltration into sclera, vessels, and ciliary body.
  • Arcurate and network vascular patterns were linked to systemic metastasis and local invasion; epithelioid and mixed cell types correlated with severe outcomes.

    • Impact:

    • Provides crucial insights into the histopathological markers predicting uveal tumor behavior.
    • Aids in refining prognostic assessments and treatment strategies for uveal malignancies.
    • Highlights the significance of vascular patterns and cellular morphology in understanding tumor invasiveness and metastatic potential.
