RESUMO
OBJECTIVE: To investigate the antitumor effect of recombinant Endostatin adenovirus (Ad-E) with carboplatin in mice with Lewis lung cancer. METHODS: C57BL/6 mice bearing Lewis lung cancer received Ad-E and carboplatin respectively or in combination. The tumor volume, tumor net weight, survival time and side effects were observed. Histological analysis was conducted to assess microvessel density (MVD) within tumor tissue and apoptotic cells were identified using the TUNEL assay. RESULTS: Compared with the control groups, the combination treatment significantly suppressed the tumor growth and prolonged survival time of the mice without obvious side-effects. The histological analysis revealed the combination treatment led to a decreased MVD and increased percent apoptosis in LL/2 tumors. CONCLUSION: Our studies indicate that a combination of Ad-E with carboplatin can present better antitumor effects without obvious side-effect.
