Treatment Outcome of Patients with Unresectable Stage IVB Head and Neck Squamous Cell Carcinoma Receiving Induction Chemotherapy with Docetaxel, Cisplatin, and Fluorouracil

摘要


Background: The aim of this study was to evaluate the treatment outcomes and predictors for patients with locally advanced unresectable stage IVB head and neck squamous cell carcinoma (HNSCC) receiving induction chemotherapy (IC) with docetaxel/cisplatin/5-fluorouracil (TPF) followed by concurrent chemoradiation (CCRT). Methods: Data from 80 patients with locally advanced unresectable stage IVB HNSCC who received TPF followed by CCRT from August 2010 to December 2012 at Kaohsiung Chang Gung Memorial Hospital were retrospectively analyzed. Clinicopathological parameters were obtained from the medical records. Results: The overall response rate to IC with TPF was 68.8%. The 12-month progression-free survival (PFS) and 2-year overall survival (OS) rates of these patients were 46% and 49.6%, respectively. Univariate analyses showed that those patients who had a clinical N classification N0/N1, could receive salvage surgery, and who responded well to IC had a significantly superior 12-month PFS rate and 2-year OS rate. Multivariate analysis also showed that clinical N classification N0/N1, undergoing salvage surgery, and being good responsiveness to IC were independent prognosticators for superior PFS and OS. Among these 80 patients, Grade 3 and Grade 4 neutropenia were noted in 13 (16%) and 9 (11%) patients, respectively. Conclusions: The results of our study suggest that IC with TPF followed by CCRT is a feasible and active treatment modality for patients with locally advanced stage IVB HNSCC, and that salvage surgery is suggested in these patients if they are operable after CCRT.
