Summary
Supraomohyoid neck dissection for oral cavity squamous cell carcinoma showed a 6% recurrence rate. Postoperative radiotherapy did not significantly impact recurrence in patients with histopathologically positive nodes.
Area of Science:
- Oncology
- Head and Neck Surgery
- Cancer Metastasis
Background:
- Squamous cell carcinoma of the oral cavity is a significant health concern.
- Lymphatic metastasis is a critical prognostic factor.
- Supraomohyoid neck dissection is a common surgical approach.
Purpose of the Study:
- To evaluate lymphatic metastasis recurrence after supraomohyoid neck dissection.
- To assess the impact of postoperative radiotherapy on recurrence rates.
Main Methods:
- Nonrandomized retrospective study of 32 patients with oral cavity squamous cell carcinoma.
- 36 supraomohyoid neck dissections (31 elective, 5 therapeutic).
- Follow-up of at least 2 years, evaluating neck tumor recurrence based on clinical and histopathological findings.
Main Results:
- Overall recurrence rate was 6% (2 patients).
- Recurrence occurred in 3% of clinically negative necks and 20% of clinically positive necks.
- No statistically significant difference in recurrence based on node status or radiotherapy use.
Conclusions:
- Clinically positive nodes were associated with a 6.3-fold higher recurrence risk compared to clinically negative nodes.
- Postoperative radiotherapy did not alter regional recurrence rates in patients with histopathologically positive nodes.
- Neck tumor recurrence was not significantly influenced by node positivity or radiotherapy use.
