Observation on the curative effect of conformal intensity-modulated radiotherapy for nasopharyngeal carcinoma

Abstract

Objective To analyze the curative effect of conformal intensity-modulated radiotherapy for nasopharyngeal carcinoma. Methods 152 patients with nasopharyngeal carcinoma who received treatment in our hospital were selected, and all of the patients were treated with dynamic or classical conformal intensity-modulated radiotherapy. Results The total effective rate of treatment was 90.79%; and the local tumor control rate in 1 year was 99.3%, and that in 2 years was 97.4%, and that in 5 years was 93.4%. Among patients with nasopharyngeal carcinoma after conformal intensity-modulated radiotherapy, those survived 1 year accounted for 99.3%, and those survived 2 years for 91.5%, and those survived 5 years for 84.2%. Most of the acute reactions were at grade 1-3, rarely at grade 4. Conclusion For patients with nasopharyngeal carcinoma, conformal intensity-modulated radiotherapy is evenly distributed, which can reduce the acute response and effective control the local tumor's development; therefore, it is an ideal radiation therapy for the treatment of nasopharyngeal carcinoma in clinical practice.
