报道102例外阴白斑和鳞癌细胞中ras癌基因产物P_(21)的检测。检测结果显示,正常组与各组存在显著差别(P<0.05～0.01),良性病变与不典型增生、鳞癌组之间存在显著差别(P<0.05～0.01),不典型增生与鳞癌组之间无显著差别(P>0.05),说明P_(21)ras检测可作为良恶性病变之间的鉴别手段。
The detection of 102 cases of leukoplakia and squamous cell carcinoma cells ras oncogene P_ (21) detection. The results showed that there was a significant difference between the normal group and each group (P <0.05 ~ 0.01), benign lesions and dysplasia, squamous cell carcinoma was significantly different (P <0.05 ~ 0.01), atypical hyperplasia and squamous cell carcinoma (P> 0.05), indicating P_ (21) ras detection can be used as a differential method between benign and malignant lesions.
