INTRODUCTION AND AIM: Locally advanced head and neck squamous cell carcinoma (LA-Hnscc) is a true therapeutical challenge in the modern era and the scientific community is trying to face this challenge with new therapeutical strategies, including combinations of monoclonal antibodies and radiation therapy. The aim of this study is to evaluate clinical outcomes in LA-Hnscc patients unfit to receive platinum-based chemotherapy, treated with concurrent simultaneous integrated boost-intensity modulated radiotherapy (Sib-Imrt) + cetuximab (Ctx) in daily clinical practice. METHODS: LA-Hnscc patients not included in other prospective studies treated in 4 Italian radiotherapy units (2 Messina, 1 Rome, and 1 Lecce) using Sib-Imrt and Ctx were included in this study. Acute and late toxicities and overall survival (OS) have been evaluated. RESULTS: Data regarding 27 patients with squamous tumour were collected and reviewed. The primary tumour sites were oropharynx in 14 patients (51.9%), oral cavity in 7 (25.9%), larynx in 3 (11%) and other sites in 3(11%). There were 20 (74%) patients had stage IV (16 IVa and 4 IVb). Complete remission was observed in 18 patients (66.7%), a partial remission in 4 (14.8%) whilst 4 had a progression disease (14.8%). After 3 year of follow-up 7/27 patients were deaths. The OS was 95.5%, 62.5% and 52.9% respectively at 1,2 and 3 years. Acute toxicities were observed in all treated patients (mucositis, dermatitis and dysphagia) while 66.7% of patients developed late toxicities. All observed toxicities were grade 1 to 3 and just 1 patient developed a G4 toxicity. CONCLUSION: The concurrent bio-radiotherapy of Sib-Imrt and cetuximab is feasible in real-life daily clinical practice for LA-Hnscc patients unfit for platinum-based chemoradiotherapy.

Abstract

INTRODUCTION AND AIM: Locally advanced head and neck squamous cell carcinoma (LA-Hnscc) is a true therapeutical challenge in the modern era and the scientific community is trying to face this challenge with new therapeutical strategies, including combinations of monoclonal antibodies and radiation therapy. The aim of this study is to evaluate clinical outcomes in LA-Hnscc patients unfit to receive platinum-based chemotherapy, treated with concurrent simultaneous integrated boost-intensity modulated radiotherapy (Sib-Imrt) + cetuximab (Ctx) in daily clinical practice. METHODS: LA-Hnscc patients not included in other prospective studies treated in 4 Italian radiotherapy units (2 Messina, 1 Rome, and 1 Lecce) using Sib-Imrt and Ctx were included in this study. Acute and late toxicities and overall survival (OS) have been evaluated. RESULTS: Data regarding 27 patients with squamous tumour were collected and reviewed. The primary tumour sites were oropharynx in 14 patients (51.9%), oral cavity in 7 (25.9%), larynx in 3 (11%) and other sites in 3(11%). There were 20 (74%) patients had stage IV (16 IVa and 4 IVb). Complete remission was observed in 18 patients (66.7%), a partial remission in 4 (14.8%) whilst 4 had a progression disease (14.8%). After 3 year of follow-up 7/27 patients were deaths. The OS was 95.5%, 62.5% and 52.9% respectively at 1,2 and 3 years. Acute toxicities were observed in all treated patients (mucositis, dermatitis and dysphagia) while 66.7% of patients developed late toxicities. All observed toxicities were grade 1 to 3 and just 1 patient developed a G4 toxicity. CONCLUSION: The concurrent bio-radiotherapy of Sib-Imrt and cetuximab is feasible in real-life daily clinical practice for LA-Hnscc patients unfit for platinum-based chemoradiotherapy.
