Abstract

Purpose

To explore lymph node-related risk factors and investigate the benefit of different adjuvant therapy strategies in hypopharyngeal squamous-cell carcinoma (HPSCC) patients with nodal metastasis (N +).

Methods

We conducted a retrospective review covering 266 HPSCC patients with nodal metastasis. Kaplan–Meier curves and Cox proportional hazard models were utilized to evaluate recurrence-free survival (RFS) and independent risk factors.

Results

pT3-T4, extranodal extension, lymphovascular invasion, and lower lymph node involvement were high-risk factors leading to poorer RFS in N + HPSCC patients. Patients were classified into three groups based on the recursive-partitioning analysis (RPA). Postoperative chemoradiation significantly improved RFS in patients in the high-risk group (p < 0.001). For patients in the low- and intermediate-risk groups, the application of adjuvant therapies showed no significant benefit on RFS (p = 0.74 and 0.53, respectively).

Conclusions

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.
