Area of Science:

  • Oncology
  • Dermatology
  • Surgical Pathology

Background:

  • Merkel cell carcinoma (MCC) is a rare, aggressive skin cancer.
  • It primarily affects elderly white patients, often on the head and neck.
  • MCC has a high risk of local recurrence, lymphatic spread, and distant metastasis.

Purpose of the Study:

  • To outline the current treatment strategies for Merkel cell carcinoma at our institution.
  • To highlight the challenges in managing this rare and aggressive neoplasm.
  • To describe the multidisciplinary approach to MCC treatment.

Main Methods:

  • Surgical excision with wide margins or Mohs' micrographic surgery for primary lesions.
  • Post-operative radiation therapy to the excision site.
  • Sentinel lymph node biopsy followed by dissection and radiation if positive.
  • Adjuvant chemotherapy for high-risk local disease or metastases.
  • Salvage chemotherapy and radiation for distant metastases.

Main Results:

  • The abstract does not contain specific results, but outlines a comprehensive treatment protocol.
  • The described protocol addresses local control, nodal status, and metastatic disease.
  • Management is tailored based on risk factors and disease stage.

Conclusions:

  • Merkel cell carcinoma requires a multimodal treatment approach.
  • Management strategies include surgery, radiation, and chemotherapy.
  • Ongoing challenges include high rates of recurrence and metastasis.
