目的研究P16INK4a、Ki-67在宫颈癌前病变中的表达及早期诊断价值。方法宫颈活检标本92例,采用免疫组织化学PV-9000二步法检测宫颈鳞癌28例,CIN 45例(CINⅢ级17例、CINⅡ级7例、CINⅠ级21例),炎性病变19例。结果在宫颈癌、CIN病变、宫颈炎P16INK4a的阳性表达率分别为100%、44.4%和10.5%,Ki-67的阳性表达率分别为100%、51.11%、21.05%,三组不同病变比较均差异有显著性(P<0.001)。P16INK4a与Ki-67表达存在正相关(r2=0.893,P<0.001)。结论 P16INk4a、Ki-67联合检测可以提高宫颈癌的早期诊断率。
Objective To study the expression and early diagnosis of P16INK4a and Ki-67 in cervical precancerous lesions. Methods Cervical biopsy specimens were obtained from 92 patients with cervical squamous cell carcinoma by immunohistochemical PV-9000 two-step method, including 28 cases of cervical squamous cell carcinoma, 45 cases of CIN (17 cases of CINⅢ, 7 cases of CINⅡ, 21 cases of CINⅠ) and 19 inflammatory lesions. Results The positive rates of P16INK4a in cervical cancer, CIN lesions and cervicitis were 100%, 44.4% and 10.5%, respectively. The positive expression rates of Ki-67 were 100%, 51.11% and 21.05% The difference was significant (P <0.001). There was a positive correlation between P16INK4a and Ki-67 (r2 = 0.893, P <0.001). Conclusion P16INk4a, Ki-67 combined detection can improve the early diagnosis of cervical cancer.
