ABSTRACT
OBJECTIVE@#To investigate the tumor regression and local immune function in nasopharyngeal carcinoma patients treated with p53 gene therapy.@*METHOD@#The two-step immunohistochemical was done to detect the expression of tumor-infiltrating lymphocytes (TIL) T-cell receptor-CD3, CD4, CD8 and B cell receptor-CD20 in the primary tumor tissue of nasopharyngeal carcinoma. Nasal endoscopy with MRI or CT was used for evaluation of tumor size.@*RESULT@#The expression of CD3, CD4, CD8 was significantly increased after p53 gene treatment (P 0.05). In conventional treatment group, CD3, CD4, CD8 and CD20 (P > 0.05) did not show any significant difference. In gene therapy group at 3 months after treatment, 20 patients had achieved CR, 10 PR, 1 SD, 1 PD. In conventional treatment group, 11 patients had achieved CR, 12 PR,5 SD,3 PD. The response rate between treatment group and control group (CR+PR) was different (P < 0.05). CD3 and CD4 expression was correlated with tumor regression rate (P < 0.05, P < 0.01), and CD8 expression was correlated with the CR rate (P < 0.05).@*CONCLUSION@#T cells are the most proliferative cell of TII. in NPC patients after p53 gene therapy The local cellular immune status is positively correlated with tumor regression rate.
