Merkel cell carcinoma, a rare and aggressive skin cancer, requires prompt diagnosis and treatment. Radiosensitivity highlights radiation therapy

Area of Science:

  • Oncology
  • Dermatopathology

Background:

  • Merkel cell carcinoma (MCC) is a rare, aggressive neuroendocrine skin cancer.
  • Characterized by rapid growth and distinct histological features.

Observation:

  • Tumor cells express specific markers: cytokeratins 8, 18, 19, 20, neurofilament, synaptophysin, chromogranin, and neuron-specific enolase.
  • MCC frequently recurs locally (25-77%) and metastasizes to lymph nodes (50%).

Findings:

  • The 5-year survival rate for MCC ranges from 30-74%.
  • Merkel cell carcinomas demonstrate high radiosensitivity.

Implications:

  • Radiation therapy should be integral to the treatment of MCC at all stages.
  • Effective management necessitates rapid diagnosis and a multimodal therapeutic approach.
