Chemodectomas: review and report of nine cases.
We have reviewed the broad spectrum of disease caused by chemodectomas. This spectrum extends from the benign to the aggressively malignant with many graduations in-between. Our analyses included cases from the literature and nine new cases seen over the past twenty-five years. Surgery as the primary and most definitive form of therapy, is recommended if feasible, with total excision as the goal, in both benign and malignant histologies. An excellent outcome is to be expected in benign cases. At present, no predictor exists to foretell the behavior of malignant lesions, which can range from the aggressive to the slowly progressive. Both radiotherapy and chemotherapy have been tried in malignant cases. No consistent good result has occurred from the use of either. The future will hopefully bring us more effective therapy.
