Risk stratification of postoperative recurrence in hypopharyngeal squamous-cell carcinoma patients with nodal metastasis.

The novel risk stratification for N + HPSCC patients can predict the risk of postoperative recurrence effectively. Adjuvant chemoradiation is preferred for patients in the high-risk group as it lowers risk of recurrence. Conversely, for patients in the low- and intermediate-risk groups, regular observation and follow-up strategies are a valid form of treatment.
