Summary
Selective neck dissection is a safe and effective treatment for oral cavity cancers in patients without lymph node metastasis. It minimizes surgical morbidity and does not compromise survival rates.
Area of Science:
- Head and Neck Surgery
- Surgical Oncology
- Oral Cancer Management
Background:
- The management of the N0 neck in oral cavity squamous cell carcinoma remains a challenge.
- Elective treatment aims to detect and manage occult nodal metastases while minimizing morbidity.
Purpose of the Study:
- To evaluate the therapeutic role and outcomes of selective neck dissection (SND) in clinically node-negative (N0) patients with oral cavity, pharynx, and larynx squamous cell carcinoma.
Main Methods:
- A retrospective review of 54 patients who underwent 72 SNDs over 6 years for squamous cell carcinoma.
- Preoperative data, including tumor and patient characteristics, were recorded.
- Follow-up averaged 59 months, with outcomes including pathologic nodal status, recurrence, and survival meticulously documented.
Main Results:
- 81% of patients were confirmed node-negative postoperatively (N0/Np0).
- The neck recurrence rate was significantly lower in node-negative patients (7%) compared to those with occult metastases (N0/Np+, 50%).
- Salvage treatment for nodal recurrence was largely unsuccessful.
Conclusions:
- Selective neck dissection is a viable option for N0 patients, offering therapeutic benefits.
- SND may reduce surgical morbidity in the N0/Np+ population.
- Early detection and management of occult nodal disease are critical for improved outcomes.
