abstract="&lt;p&gt;&lt;b&gt;OBJECTIVE&lt;/b&gt;To evaluate the feasibility and efficacy of cytocine deaminase-thymidine kinase (CD-TK) fusion double suicide gene therapy using adenovirus mediated CD-TK gene and green fluorescent rotein (GFP) gene combined with ganciclovir(GCV) or 5-flourocytosine(5-FC) in a murine subcutaneous bladder carcinoma model.&lt;/p&gt;&lt;p&gt;&lt;b&gt;METHODS&lt;/b&gt;A replication defective adenovirus vector containing CD-TK gene was used. Subcutaneous tumors were established in syngenic C57BL/6 female mice with 1 x 10(6) Mb49 cells. Intratumoral injection of AdCD-TK (1.58 x 10(8) PFU, qd x days) in combination with GCV (40 mg.kg(-1).d(-1), ip, qd x 10 days) or 5-FC (400 mg.kg(-1).d(-1), ip, qd x 10 days) was administered in vivo for the determination of treatment efficacy in separate controlled experiments.&lt;/p&gt;&lt;p&gt;&lt;b&gt;RESULTS&lt;/b&gt;In vivo experiments demonstrated that the mean volume of tumor in the group of AdCD-TK/GCV(326.58+/-109.56 mm(3)), AdCD-TK/5-FC (235.33+/-62.94 mm(3)) and AdCD-TK/(GCV+5-FC) (23.58+/-6.78 mm(3)) was reduced significantly compared with that of control group (993.51+/-158.32 mm(3)) (P=0.00), the mean volume of tumor in the group of AdCD-TK/(GCV+5-FC) was significantly less than that in the group of AdCD-TK/GCV or AdCD-TK/5-FC (P=0.04). Tumor necrosis was revealed by histomorphology compared with control animals.&lt;/p&gt;&lt;p&gt;&lt;b&gt;CONCLUSIONS&lt;/b&gt;Adenovirus mediated CD-TK double suicide gene combining with GCV or 5-FC could provide an effective therapy in an experimental murine bladder carcinoma by significantly inhibiting tumor growth. The treatment efficacy of AdCD-TK combining GCV and 5-FC was superior to that of AdCD-TK combining GCV or AdCD-TK combining 5-FC.&lt;/p&gt;<p /><p>Language: zh</p>",
