Summary

Delayed metastases from midfacial squamous cell carcinoma present a favorable prognosis. Careful follow-up is crucial for detecting late-stage cervical metastasis in these patients.

Area of Science:

  • Oncology
  • Head and Neck Surgery
  • Dermatology

Background:

  • Metastases from squamous cell carcinomas of the skin and mucosa can exhibit delayed presentation.
  • Late-onset metastases may impact prognosis following standard treatments for midfacial cancers.

Purpose of the Study:

  • To analyze the characteristics and outcomes of delayed regional metastases from midfacial squamous cell carcinoma.
  • To identify high-risk metastatic sites and inform treatment strategies for these cancers.

Main Methods:

  • Retrospective review of 13 patients with midfacial squamous cell carcinoma and delayed regional metastases.
  • Analysis of primary tumor locations, time to metastasis, clinical staging, and treatment modalities (neck dissection, radiotherapy).
  • Evaluation of surgical outcomes, including nerve sacrifice and extracapsular spread, and oncologic follow-up.

Main Results:

  • 12 of 13 patients presented with metastases >11 months after primary tumor treatment.
  • Perifacial lymph nodes were the most common site of metastasis.
  • Extracapsular spread was observed in 11 patients, with 8 of 9 clinically N1 patients affected.
  • No regional recurrences were noted after a minimum follow-up of 1 year.

Conclusions:

  • Midfacial squamous cell carcinoma can metastasize to regional lymph nodes with significant delay.
  • Delayed presentation appears associated with a more favorable treatment response.
  • Perifacial nodes are the primary risk for metastasis; prophylactic neck treatment may not be necessary, but vigilant follow-up is essential.
