摘要
Objective :To investigate the relationship between p53 -protein overexpression in esophageal and cervical squamous cell cancer and their clinical radiosensitivity. Methods: The immuno-histochemical assays were done for 52 cases with esophageal and cervical squamous cell cancer. The relationship between the assay results and short-term radiotherapy was investigated. Results: p53 overexpression was 52. 38% and 35. 48% respectively, in esophageal cancer and cervical cancer; p53 over-expression in high differentiated squamous cell cancer was lower than those in moderate and poor differentiated cases(P<0. 05). There was no relationship between p53 overexpression and stages(P> 0. 05). In the cases of cervical cancer, p53 overexpression had the less short-term effect(P< 0. 05), and In esophageal cancers, there was no relationship with radiotherapy effect(P>0. 05). Conclusion:This study suggests that y53 gene lias the certain relationship with tumor radiosensitivity.
