目的：为了提高鼻咽低分化鳞癌治疗５年生存率及生活质量。方法：应用真彩色图像分析，对３２例鼻咽低分化鳞癌进行ＤＮＡ分析，其中１年内复发２０例，５年内未复发１２例。结果：两组肿瘤细胞ＤＮＡ指数和ＤＮＡ倍体分布，经统计学处理，具有显著差异。结论：ＤＮＡ指数及ＤＮＡ倍体越大，肿瘤恶性程度越高，越容易复发和转移，故应根据肿瘤细胞不同异倍体，采取不同治疗方案，才能达到较好的治疗效果
Objective: To improve the 5-year survival rate and quality of life of nasopharyngeal poorly differentiated squamous cell carcinoma. Methods: Real-color image analysis was used to analyze 32 cases of poorly differentiated squamous cell carcinoma of the nasopharynx. Among them, 20 cases recurred in one year and 12 cases did not recurrent in 5 years. Results: DNA index and DNA ploid distribution of tumor cells in two groups were significantly different after statistical analysis. Conclusion: The larger DNA index and DNA ploidy, the higher the degree of tumor malignancy, the more likely to relapse and metastasis, so should be based on aneuploid tumor cells with different treatment options in order to achieve better therapeutic effect
