Abstract
OBJECTIVE
We aimed to determine the prognostic value of lymphovascular invasion (LVI) in pyriform sinus carcinoma (PSC) after primary surgery with adjuvant radiotherapy (RT) or concurrent chemoradiotherapy (CCRT).
METHODS
Patients who underwent primary surgery at our institution between 2000 and 2018 were included in this study and retrospectively analyzed. The endpoints were locoregional recurrence (LRR), distant metastasis (DM), and disease-specific survival (DSS).
RESULTS
We reviewed 117 patients with PSC. LVI was identified in 29 patients (24.8%). The 5-year LRR rate, DM rate, and DSS rate were 29.4%, 31.7%, and 45.9%, respectively. Tumors with LVI were associated with a significantly higher LRR (P = 0.002, HR 3.678, 95% CI 1.646-8.218) and DM (P = 0.003, HR 3.666, 95% CI 1.543-8.709) and a lower DSS (P = 0.001, HR 2.814, 95% CI 1.519-5.213) in multivariate analysis.
CONCLUSION
LVI is a significant predictor of poor prognosis in patients with PSC treated with surgery plus adjuvant RT/CCRT.
