Objectives/Hypothesis:
To assess the risk of level V nodal involvement for early T-stage and node positive oropharyngeal squamous cell carcinoma (ORO-SCC).
Methods:
Retrospective analysis performed on patients with ORO-SCC and clinically positive lymph nodes who had undergone upfront elective dissection of level V before definitive chemoradiotherapy. Pathological data collected and prevalence of involvement of level V determined.
Results:
A total of 119 patients had level V dissection. The prevalence of pathologically positive lymph nodes in level V was 3.4% (4/119). Moreover, it was observed only in the presence of pathological involvement of multiple other nodal levels (4/52 patients, 7.7% vs. 0/67 in patients with a single nodal station involved, chi(2)P = .02).
Conclusions:
Subclinical involvement of level V in ORO-SCC is rare, especially in the presence of disease confined to a single nodal level. The present data do not support its dissection after primary chemoradiotherapy.
