- Abstract:
- PURPOSE: Three cases of malignant carotid body paragangliomas with nodal metastases are reported. PATIENTS AND METHODS: Between 1985 and 1994, 3 female patients (51 to 65 years of age) were referred for postoperative radiotherapy after complete (2) or incomplete (1) surgical excision of a malignant carotid paraganglioma (Shamblin III). Preoperative angiographic embolization of the tumor-supplying arteries was performed in all cases. In 2 patients resection of the internal carotid artery and reconstruction by saphenous vein graft was necessary. Continuous course radiotherapy of the tumor bed (50 to 56 Gy/2 Gy) and regional lymph nodes (50 Gy) using photon beams was delivered in 2 patients. The third patient having had incomplete resection cancelled radiotherapy after 4 Gy. RESULTS: Within an observation time of 110 and 119 months no evidence of recurrence was obtained in both patients irradiated postoperatively. The third patient died of progressive disease. Twelve months after the withdrawn irradiation she presented with a tumor progression into the brain and an ulcerated mass on the right side of the neck and was irradiated consecutively for palliation (Figures 1a to 1f). In none of the patients severe acute or late radiation-induced complications were observed. CONCLUSION: In patients with malignant paraganglioma moderate dose postoperative radiotherapy of the tumor bed and regional lymph nodes is well tolerated. It seems to be effective to prolong local control after surgery, to eradicate microscopic lymphatic disease and eventually to postpone further spreading.
