Summary

Lymph node metastases in the lower neck impact survival, with posterior triangle nodes offering better outcomes than supraclavicular fossa nodes. Head and neck cancers showed specific associations but overall survival was not significantly different based on primary tumor site or histology.

Area of Science:

  • Oncology
  • Surgical Pathology
  • Cancer Research

Background:

  • Lymph node metastases in the lower neck, specifically the supraclavicular fossa and posterior triangle, are recognized indicators of poor prognosis.
  • Limited systematic research exists on the prognostic implications of lower neck lymph node involvement.

Purpose of the Study:

  • To investigate the association between variables and tumor-specific survival in patients with lower neck lymph node metastasis.
  • To identify prognostic factors influencing survival in this patient cohort.

Main Methods:

  • Retrospective analysis of a prospective database of 168 patients with lower neck node metastasis over 35 years.
  • Statistical analysis included chi-square, categorical modeling, Kaplan-Meier survival curves, log-rank tests, and Cox proportional hazard models.

  • Variables analyzed included tumor site, node level, histology, and laterality.

    • Main Results:

    • Head and neck tumors were significantly associated with squamous histology and supraclavicular node involvement.
    • Survival was not significantly different between head and neck and non-head and neck metastases (5-year survival: 30% vs. 10%).
    • Posterior triangle metastases showed significantly better survival than supraclavicular metastases, confirmed by multivariate analysis. Laterality and histology did not significantly impact survival.

    Conclusions:

    • The location of lower neck lymph node metastasis is a critical prognostic factor, with posterior triangle involvement indicating a better survival outlook than supraclavicular fossa involvement.
    • While head and neck primaries show specific associations with histology and node location, primary site and histology do not independently predict survival in this cohort.
    • Further research into the management of lower neck lymph node metastases is warranted.
