ABSTRACT
PURPOSE:
The aim of this study was to propose the clinical radiotherapy-related typing and to summarize proportional distribution of radiotherapy-related types of nasopharyngeal carcinoma (NPC). METHODS AND MATERIALS A total of 842 cases of NPC were randomly selected. According to 5-year follow-up results after radiotherapy, NPC was subdivided into four types Type I (no primary and regional recurrence and no distant metastasis), Type II (primary or regional recurrence and no distant metastasis), Type III (no primary and regional recurrence, and distant metastasis), and Type IV (primary or regional recurrence, and distant metastasis). Proportion of the four types and relationship between this typing and Zhi-guang Xie typing were analyzed.RESULTS:
Distribution of radiotherapy-related types of NPC were 50.6%, 23.2%, 20.7%, and 5.6% for Types I, II, III, and IV, respectively. For Types D and AD of Zhi-guang Xie typing system and Stage III and IV of the 1992 Fuzhou staging system, the proportion of Type III was greater than that of Type II; and for Type A and Stage I and II, there was a larger proportion of Type II than that of Type III.CONCLUSION:
Radiotherapy-related typing, as a new clinical subclassification, could be supplementary for previous clinical typing and staging.
