Patterns and Quality of Care for Head and Neck Cancer in Belgium: A Population-Based Study.

OBJECTIVES:We evaluated the quality of care for patients with squamous cell carcinoma (SCC) of the oral cavity, oropharynx, hypopharynx or larynx in Belgium.METHODS:Data of the Belgian Cancer Registry were coupled with health insurance data and hospital discharge data. Quality of care and the association with hospital volume were evaluated based on six quality indicators.RESULTS:Half of the patients were treated with primary radiotherapy, with or without systemic therapy (49.7%) and 38.1% with surgery, with or without (neo)adjuvant therapy. Single-modality treatment was provided to 78.1% of early-disease patients. Of the patients with cN0 disease, 56.4% underwent neck dissection. Postoperative radiotherapy was completed timely in 48.5% of patients. Concomitant chemotherapy was administered to 58.2% of patients <70 years with locally advanced disease. Imaging of the neck after radiotherapy was performed appropriately in 32.7% of patients. Variability between centres was considerable. No clear relationship between hospital volume and results of the individual QIs was observed.CONCLUSIONS:Results show that for the measured QIs, targets are not met and variability between centres is considerable. Through individual feedback, centres are motivated to improve the quality of care for head and neck cancer patients in Belgium.
