Abstract
PURPOSE: To determine the role of preoperative concurrent chemoradiotherapy in the treatment of locally advanced head and neck squamous cell carcinoma (HNSCC).
METHODS: A total of 222 patients with stage III/IVA-B HNSCC were randomly assigned to receive preoperative concurrent chemoradiotherapy (Pre-S CRT, weekly cisplatin 30mg/m2) or preoperative radiotherapy alone (Pre-S RT). Survival analysis was estimated by the Kaplan-Meier method and compared by the log-rank test.
RESULTS: With a medial follow-up of 59 month, the 5-year overall survival (OS), progression-free survival (PFS), distant metastasis-free survival (DMFS) of Pre-S CRT v Pre-S RT group were 53.8% v 39.0% (hazard ratio [HR], 0.74, 95% CI, 0.50 to 1.10, P = 0.13), 53.2% v 38.7%, (HR, 0.69, 95% CI, 0.47 to 1.01, P =0.06), and 80.4% v 68.1% (HR, 0.53, 95% CI, 0.28 to 0.98, P = 0.04), respectively. In patients with larynx-hypopharynx primaries, the 5-year OS, PFS and DMFS of Pre-S CRT v Pre-S RT were 62.7% v 38.8% (HR, 0.59, 95% CI 0.35 to 1.02, P = 0.054), 63.1% v 39.9% (HR, 0.52; 95% CI 0.30 to 0.89, P = 0.03) and 86.2% v 63.3% (HR, 0.35, 95% CI 0.15 to 0.82, P = 0.01), respectively.
CONCLUSION: The addition of weekly cisplatin concurrent to preoperative RT does not improve OS, but improve DMFS in locally advanced HNSCC. However, in a subset of patients with the larynx-hypopharynx primaries, preoperative chemoradiotherapy has significantly improved PFS and DMFS, and has also provided a borderline benefit in OS in comparison with preoperative radiotherapy alone.
