Clinical Features and Management of Distant Metastases from Nasopharyngeal Carcinoma

Abstract

This is a retrospective study of 90 patients who developed distant metastases after radical radiotherapy for nasopharyngeal carcinoma. The skeleton was the commonest site of distant metastases. Clubbing, hypercalcemia and malignant fever occurred in about 10% of patients with pulmonary, skeletal and hepatic metastases respectively. An effective chemotherapeutic regimen for palliation of pulmonary and hepatic metastases was cisplatinum/carboplatin-5FU which gave a complete response rate of 29% and partial response rate of 21%. This was considered superior to some non-cisplatinum-containing regimens. One patient with hepatic metastases had good palliation by hepatic irradiation. The median survival of all patients with distant metastases was eight months. Five (6%) patients survived more than two years with one surviving free of disease at 31 months. Hepatic metastases and spinal cord compression were associated with short survivals.
