Abstract
OBJECTIVE: This study aimed to investigate the efficacy of induction chemotherapy followed by concurrent chemotherapy and helical tomotherapy in patients with T4b squamous cell carcinoma of the nasal cavity and paranasal sinus in regard to orbital organ preservation and quality of life.
METHODS: Clinical data of 28 cases of patients with orbital involvement of T4b squamous cell carcinoma of the nasal cavity and paranasal sinus who received multimodal treatment for orbital organ preservation between May 2008 and September 2015 were retrospectively analysed. The treatment efficacy and side effects were assessed. The study included 18 male and 10 female patients. All patients were treated with induction chemotherapy followed by concurrent chemoradiotherapy and/or epidermal growth factor receptor inhibitor. Helical tomotherapy was applied as radiotherapy. Adverse reactions to the chemotherapy were assessed according to Common Terminology Criteria for Adverse Events, Version 4. The overall survival rate, local control rate and rate of effective orbital preservation were calculated using the Kaplan-Meier method.
RESULTS: All patients completed the planned chemotherapy, and 27 (96.4%) of the patients completed the planned radiotherapy cycle. After the multimodal treatment, the 3-year overall survival, local control rate and rate of effective orbital preservation of the patients were 59.2%, 80.2% and 77.8%, respectively.
CONCLUSIONS: Multimodal treatment could preserve the orbital organs of patients with T4b squamous cell carcinoma of the nasal cavity and paranasal sinus, achieve relatively ideal organ protection and survival rates and improve the quality of life of patients with advanced squamous cell carcinoma of the nasal cavity and paranasal sinus, thus providing a new treatment option for these patients.
