Abstract:
Objective To study the expression of p53,p16,PCNA protein in esophageal carcinoma and its relationship to sexual distinction,the location of disease,the biological level,the depth of invasion and lymph node metastasis.Methods 118 patients with esophageal carcinoma were included in the study,all of them were treated for the first time.p53,p16 and PCNA protein in the 118 cases of esophageal carcinoma were detected by immunohistochemical assay(SP technique). Results The positive expression of p53, p16, PCNA protein in 118 patients was 80 %(92/118),42%(50/118)and 97%(115/118),respectively.The positive expression of p53,PCNA protein were irrelated to the sexual distinction,the location of disease,the biological level,the depth of invasion and the lymph node metastasis.The loss of p16 was significantly related to the depth of invasion and the lymph node metastasis(P
