目的:探讨鼻咽癌放疗后肿瘤复发的CT表现。方法:分析有完整临床及CT资料且经病理证实的鼻咽癌220例。结果:鼻咽癌放疗后肿瘤复发的CT表现为鼻咽壁不同程度增厚,肿物边缘均不规则,密度不均匀,增强CT扫描病变呈轻、中度强化;鼻咽癌放疗后4~6个月、7~12个月、13~24个月、25个月后鼻咽原发肿瘤消退情况与肿瘤复发有统计学差异(P<0.01)。结论:探讨鼻咽癌放疗后复发CT表现有利于监测肿瘤放疗后转归并对复发病例早期控制。
Objective: To investigate the CT findings of tumor recurrence after radiotherapy of nasopharyngeal carcinoma. Methods: There were 220 cases of nasopharyngeal carcinoma confirmed by pathology with complete clinical and CT data. Results: The CT findings of tumor recurrence after nasopharyngeal carcinoma were thickened nasopharyngeal wall to varying degrees, the edge of the tumor was irregular, the density was uneven, and the lesions of CT scan were enhanced mildly and moderately. After 4 ~ The regression rates of primary tumor of nasopharyngeal tumor and recurrence of tumor after 6 months, 7-12 months, 13-24 months and 25 months were statistically different (P <0.01). Conclusion: To investigate the CT findings of recurrence of nasopharyngeal carcinoma after radiotherapy is helpful to monitor the prognosis of tumor after radiotherapy and to control early recurrence.
