Simultaneous bilateral neck dissection (SBND) is effective for advanced head and neck cancers. This procedure improves survival rates, particularly for hypopharyngeal cancers, by addressing lymph node metastasis.

Area of Science:

  • Oncology
  • Surgical Oncology
  • Head and Neck Surgery

Context:

  • Advanced head and neck squamous cell carcinoma presents significant treatment challenges.
  • Cervical lymph node metastasis is a critical prognostic factor in head and neck cancers.
  • The efficacy of simultaneous bilateral neck dissection (SBND) for advanced cases requires evaluation.

Purpose:

  • To assess the survival outcomes and patterns of lymph node metastasis in patients with advanced head and neck squamous cell carcinoma treated with SBND.
  • To determine the role of SBND in managing cervical metastasis, particularly in hypopharyngeal cancers.

Summary:

  • A study of 65 patients with advanced head and neck squamous cell carcinoma treated with SBND from 1985-1989 showed 5-year survival rates of 42%.
  • Patients without lymph node involvement had an 83% 5-year survival rate, compared to 32% with nodal involvement (p<0.005).

  • SBND revealed occult contralateral metastasis in 22% of clinically unilateral cases and 54% of clinically negative cases, highlighting the need for comprehensive staging.

    • Impact:

    • SBND is a suitable treatment for metastatic cervical cancer from head and neck primary lesions.
    • The findings suggest that controlling lymph node metastasis is crucial for improving survival in these patients.
    • SBND is particularly recommended for hypopharyngeal cancers due to the high rate of contralateral metastasis.
