[Effectiveness of improved intracavity microwave thermotherapy for nasopharyngeal carcinoma]

This study sought to evaluate the safety and effectiveness of intracavity microwave thermotherapy for nasopharyngeal carcinoma (NPC). The temperature images of the heating range were attained immediately after heating by LCP. The aim temperature (equal or over 40 degrees C) was achieved and then uniform thermal distribution in these areas was seen. Either phantoms or animal tests suggest that the temperature of all detected points are ranged from top to low: para-radiator, ipsilateral, parietal and contralateral wall of the simulated nasopharygeal cavity. Intracavity microwave thermotherapy is effective and safe for NPC by either phantoms or animal tests.
