Objectives: Induction chemotherapy (IC) followed by chemoradiation (CRT) for locally advanced squamous cell head and neck cancer (SCCHN) remains controversial in the absence of clear evidence to define its role. As part of a prospective, randomised, multicentre study of CRT for stage III/IV laryngeal/hypopharyngeal cancers (ART DECO, CRUK/10/018), we have examined the attitudes of oncologists in the United Kingdom (UK) to IC.
Materials and methods: Head and neck oncologists across the UK who expressed an interest in participating in the ART DECO trial were asked to complete a short written questionnaire designed to identify current UK practice of IC for stage III-IVb SCCHN. Completed questionnaires were returned to the clinical trials office prior to patient recruitment.
Results: Clinicians from twenty-five/48 centres (52.1%) responded. Twenty centres (80%) elected to use IC in the trial. For stage III disease, 80% of centres did not prescribe IC for T1N1 disease and 60% did not offer IC for T3N0 disease. Patients with bulky primary tumours or extensive nodal disease were more likely to receive IC. Thirteen prescribing centres (65%) use 3 drugs (docetaxel, cisplatin, and 5-fluorouracil) compared to 7 (35%) using 2 drugs (cisplatin and 5-fluorouracil). Fifteen centres (75%) prescribed 2 cycles of IC, and 5 (25%) prescribed 3 cycles. There was variation in the dosage for both the 2- and 3-drug regimens.
Conclusion: Results suggest that clinical practice in the UK is currently divided between a 2- versus 3-drug regimen for IC for specific subgroups of patients. A consensus regarding the optimal combinations and dosages is required before further optimization of systemic therapy with other cytotoxics and biological agents is attempted.
