鼻咽癌是最常见的恶性肿瘤之一,因其病变部位特殊,与重要器官相邻,多为低分化鳞状细胞癌等原因导致手术不易彻底切除,术后易复发,且放疗的5年生存率仅45%左右。本研究以鼻咽低分化鳞状细胞癌为研究对象,鼻咽炎症组织作对照,观察候选抑癌基因(IGF-2R、p27)和原癌基因(p21)在鼻咽 Nasopharyngeal carcinoma is one of the most common malignant tumors, because of its special lesion, adjacent to vital organs, mostly due to poorly differentiated squamous cell carcinoma and other reasons leading to incomplete resection of the surgery, postoperative recurrence, and 5 years of radiotherapy Survival rate is only about 45%. In this study, nasopharyngeal poorly differentiated squamous cell carcinoma was taken as the research object, nasopharyngeal inflammation tissue as a control, observed candidate tumor suppressor genes (IGF-2R, p27) and proto-oncogene (p21) in the nasopharynx
