Abstract:
Objective To investigate the effect of recombinant human endostatin(rh-Endostatin) combined with transcatheter arterial chemoembolization(TACE) on the growth and metastasis of the implanted hepatic tumor in rabbits.Methods Thirty New Zealand white rabbits were randomly divided into three groups (10 in each group)and VX_2 carcinomas were implanted in the left lobes of the livers. Fourteen days later, a catheter was inserted into the hepatic artery of rabbits with VX2 hepatic tumor and infusion was performed via the hepatic artery using physiological saline (group A), TACE (group B) and rh-Endostatin combined with TACE (group C),respectively. Five weeks later, all ribbits were sacrificed, the body weight and liver weight of animals were assessed, the hepatic index(HI) was calculated, the volume and necrotic area of the implanted tumor were measured. The presence of metastases in the liver, lungs were recorded. Results Five weeks after inoculation, the body weight of all animals decreased, the liver weight increased, His were 10.2±2.8, 8.5±6.1and 6.2±4.4 in groups A, B and C, respectively. The mean volume and necrostic areas of the implanted tumor were (36.2±3.4) cm~3 and (52.0±2.3)% in group A, (23.6±4.5) cm~3 and (63.6±3.5)% in group B, (10.9±5.1) cm~3 and (78.6±4.8)% in group C, respectively. There were statistical significance about tumor volume and necrostic areas of the tumors between group C and group A,B ( P<0.01). The numbers of metastases in the lungs were 50.3±31.3,53.6±35.1 and 16.8±18.4 , and the diameters of metastases in the lungs were (3.6±1.4) mm, (3.8±0.6) mm and (1.2±0.6) mm in groups A, B and C, respectively, the difference between group C versus other groups( P<0.01) was statistically significant. The differences of opportunity, tumor numbers and size of metastases in the liver were statistically significant. (P<0.01).Conclusion Treatment with rh-Endostatin combined with TACE can suppress the growth of tumor and tumor's metastases in lungs inVX2 implanted tumors of rabbits.
