AB - A new external radiotherapy system has been developed for head and neck cancer and a case with T2 oral floor carcinoma treated with this system is presented in this report. The system consists of real-time tumor-tracking equipment and a gold-marker implanted mouthpiece. Accuracy of the order of 2mm was achieved during the entire course of fractionated radiotherapy (a total of 52.5Gy in 15 fractions). Planning target volume became smaller compared to the conventional parallel-opposed technique. Dosevolume histogram analysis demonstrated a significant reduction in the dose to the mandible bone compared to the conventional technique. A confluent fibrinous mucositis developed in the oral floor mucosa that corresponded to 90 dose area. Mucositis in the lower gum was minimal and analgesics were not required. The patient is currently free from both tumor and complication during a follow-up period of 48 months. External radiotherapy can be an option as a curative treatment for early stage carcinoma of the floor of the mouth provided that patient set-up is rigid and reproducible.
