BACKGROUND: Induction chemotherapy for patients with head and neck cancer is widely performed, and several advantages of induction chemotherapy have been reported. However, there is currently insufficient evidence to strongly recommend induction chemotherapy. In this study, we analyzed the outcomes for patients treated with induction chemotherapy and subsequent definitive treatments.
METHODS: Operable patients with untreated oropharyngeal, hypopharyngeal and laryngeal squamous cell carcinoma treated with induction chemotherapy were included in this retrospective study. We conducted induction chemotherapy using docetaxel, cisplatin and 5-fluorouracil and performed subsequent surgical treatment or radiotherapy according to the response to induction chemotherapy.
RESULTS: A total of 65 patients were included in this study, and 50 patients (76.9%) had Stage IV tumors. The response to induction chemotherapy was CR in two patients, PR in 55 patients, and SD in eight patients. The subsequent definitive treatment was radiotherapy in 60 patients, and surgery in five patients. The 3-year overall survival rates for patients who received radiotherapy and surgery were 88.4% and 75.0%, respectively (P = 0.30). The 3-year disease-free survival rates for patients who received radiotherapy and surgery were 68.0% and 0%, respectively (P = 0.01). The 3-year laryngeal dysfunction free survival rates for patients who received RT and surgery were 77.8% and 0%, respectively (P < 0.01).
CONCLUSIONS: We achieved favorable survival outcomes and high larynx preservation rates. Our results suggest that induction chemotherapy using TPF regimen is one of the optimal treatment strategies when treating head and neck cancers. Further prospective studies with a larger cohort are required to confirm our findings.
