    Modified radical neck dissection is effective for early-stage upper aerodigestive tract cancers. Postoperative radiotherapy is recommended for specific positive node criteria, improving outcomes for squamous cell carcinoma patients.

    Area of Science:

    • Oncology
    • Head and Neck Surgery
    • Surgical Oncology

    Background:

    • Squamous cell carcinoma of the upper aerodigestive tract often requires surgical management of regional lymph nodes.
    • Modified radical neck dissection (MRND) offers a less extensive alternative to traditional radical neck dissection.
    • Evaluating the efficacy of MRND in specific clinical scenarios is crucial for optimizing treatment strategies.

    Purpose of the Study:

    • To assess the clinical benefit and oncologic outcomes of a specific modified radical neck dissection technique.
    • To determine the recurrence rates and survival in patients undergoing MRND for upper aerodigestive tract squamous cell carcinoma.
    • To identify predictive factors for recurrence and guide the use of postoperative radiotherapy.

    Main Methods:

    Related Experiment Videos

  • Retrospective analysis of 98 modified radical neck dissections in 86 patients with upper aerodigestive tract squamous cell carcinoma over a 5-year period.
  • The MRND procedure involved dissection of submaxillary and jugular chain nodes, excluding the posterior triangle.
  • Patient data included preoperative clinical assessment, histological findings, and postoperative radiotherapy status.

    • Main Results:

    • Histological positive lymph nodes were found in 56% of dissections.
    • Recurrence in the dissected neck occurred in 8 of 38 patients with positive nodes, and none with negative nodes (P < 0.05).
    • Recurrences were associated with clinically palpable nodes preoperatively; postoperative radiotherapy did not significantly alter recurrence or survival in positive node cases.

    Conclusions:

    • Modified radical neck dissection is appropriate for clinically negative necks or early regional disease (N1) in the submandibular triangle.
    • Postoperative radiotherapy is indicated for patients with more than one positive lymph node or extracapsular spread.
    • The described MRND technique provides effective regional control for selected patients with upper aerodigestive tract squamous cell carcinoma.
