Radical combined treatment of locally extensive head and neck cancer in the elderly.

PURPOSE
Few studies have described the effects of aggressive combined therapy for locally extensive head and neck cancer in the elderly. Our study evaluated the outcome of this particular cohort of patients after such treatments.


METHODS
Survival, failure, morbidity, and complication rates were determined retrospectively in 43 elderly patients with stage III or IV head and neck cancer who underwent curative surgery and postoperative radiotherapy (n = 33) or neoadjuvant, 3-drug chemotherapy plus radiotherapy (n = 10) between the years 1977 and 1992.


RESULTS
The crude survival rate at 3 years was 27% in patients managed by surgery plus radiotherapy, and 30% in individuals treated with chemoradiation; the corresponding locoregional failure rates were 23% and 30%; and the distant failure rates were 13% and 0%, respectively. The acute toxicity rate was 12% in the surgery plus radiotherapy group and 30% in the chemoradiation patients; the corresponding late complication rates were 0% and 10%. There were no toxic deaths.


CONCLUSION
Radical combined treatments can be performed safely and achieve long-term, disease-free survival in selected elderly patients with locally extensive head and neck cancer.
