Summary

Contralateral cervical lymph node metastasis in piriform sinus carcinoma increases with higher T and N stages. Lesions invading beyond the midline significantly raise metastasis risk, warranting positive neck dissection selection.

Area of Science:

  • Otolaryngology
  • Head and Neck Surgery
  • Oncology

Context:

  • Piriform sinus carcinoma is a significant cause of head and neck cancer.
  • Understanding metastasis patterns is crucial for effective treatment planning.
  • Contralateral cervical lymph node metastasis impacts prognosis and management strategies.

Purpose:

  • To identify key factors influencing contralateral cervical lymph node metastasis in piriform sinus carcinoma.
  • To analyze the relationship between tumor stage (T and N) and metastasis.
  • To assess the impact of primary lesion location relative to the midline.

Summary:

  • This study analyzed 96 piriform sinus carcinoma cases without prior treatment.
  • Contralateral cervical lymph node metastasis occurred in 32% of cases.

  • Higher T and N stages, and primary lesions extending beyond the midline, were associated with increased metastasis risk.

    • Impact:

    • Findings highlight the importance of staging and lesion location in predicting metastasis.
    • Results suggest a more aggressive surgical approach, including neck dissection, for certain cases.
    • Improved understanding can lead to tailored treatment strategies and better patient outcomes.
