Elective neck dissection during salvage laryngectomy for radiation failures can detect occult metastases, particularly in advanced glottic and supraglottic cancers. Bilateral neck dissection is recommended for recurrent T3/4 glottic and all supraglottic cancers.

Area of Science:

  • Otolaryngology
  • Surgical Oncology
  • Head and Neck Cancer Research

Background:

  • Salvage laryngectomy is a treatment option for patients with persistent or recurrent laryngeal cancer after radiation therapy.
  • The role of elective neck dissection in these cases, particularly for detecting occult metastases, requires further clarification.

Purpose of the Study:

  • To determine the incidence of occult metastases identified through elective neck dissection in patients undergoing salvage laryngectomy for radiation failure.
  • To assess the impact of elective neck dissection on survival outcomes in this patient population.

Main Methods:

  • Retrospective review of 63 patients treated with salvage surgery between 1970 and 1999.
  • Analysis of tumor stage, neck treatment, complications, surgical time, and survival data.

  • Median follow-up periods of 7.8 years for glottic and 4.5 years for supraglottic cancers.

    • Main Results:

    • Occult metastases were found in 10% of glottic cancer patients (3/31) and 20% of supraglottic cancer patients (2/10) who underwent elective neck dissection.
    • Higher rates of occult metastases (20%) were observed in glottic cancers with recurrent stage T3 or greater.
    • No significant survival advantage was found for elective neck dissection compared to expectant management in either glottic or supraglottic cancer groups.

    Conclusions:

    • Bilateral neck dissection is recommended for salvage laryngectomy in patients with recurrent T3/4 glottic tumors and all recurrent supraglottic cancers due to the elevated risk of occult metastases.
    • Factors such as cartilage and perineural invasion in the larynx are associated with an increased risk of occult metastases.
