Effect of MAb225 on radiosensitivity of Tca8113 tongue squamous cell carcinoma

, : Effect of MAb225 on radiosensitivity of Tca8113 tongue squamous cell carcinoma. Hua Xi Kou Qiang Yi Xue Za Zhi 23(4): 322-4, 328

The purpose of this study was to invest the effect of epidermal growth factor receptor monoclonal antibody MAb225 on radiosensitivity of tongue squamous cell carcinoma cell Tca8113. Tca8113 cells were treated with different concentrations of MAb225. Radiation dose survival curve was generated from clonogenic survival assay. SERPD0 and survival faction (SF2) was analysed by single hit multi-target (SHMT) radiobiological model using RADMEDIC software. Nude mice with Tca8113 tumor xenografts were treated with MAb225, radiation treatment or both of them. Tumor responses were assessed by tumor growth delay, and t test was used for statistical analysis. MAb225 enhanced the radiosensitivity of Tca8113 cells. SERD0 of Tca8113 cells treated with 0.5 mg/L MAb225 was 1.23. The survival fraction of cells treated with MAb225 was significantly decreased. Tumor radioresponse could be enhanced by MAb225 (P < 0.05). MAb225 could enhance radiosensitivity of tongue squamous cell carcinoma cell.
