The effect of age on survival and quality of life in elderly head and neck cancer patients: a long-term prospective study.

Little is known about long-term treatment outcome of elderly head and neck cancer patients and their quality of life (QOL). One hundred and eighteen older (>or=70 years) and 148 younger (45-60 years) patients with head and neck cancer were followed up for 3-6 years. In the long-term follow-up 33 younger and 24 older patients completed the EORTC QLQ-C30 and H&N35 and a questionnaire about depression. The survival rate after 3-6 years for younger patients was 36%, as compared to 31% in the older patient group. Higher tumour stages, more co-morbidity and non-standard treatment showed to be independent prognostic factors for mortality. No independent prognostic value of age could be found. The global QOL score remains roughly comparable. Even up to 6 years after treatment, we found no significant differences in survival or overall QOL between older and younger head and neck cancer patients.
