Experimental intraperitoneal continuous chemotherapy on human ovarian epithelial cancer in nude mice / 中国癌症杂志

ABSTRACT

Purpose:To evaluate the effect of continuous intraperitoneal washing chemotherapy in treating the abdominal cavity tumor of nude mice with human ovarian epithelial cancer.Methods:The abdominal cavity tumor of nude mice models was established with human ovarian serous epithelial cancer cell line SKOV 3. 20 experimental nude mice were divided into 3 groups the common treatment group(7 mice),the continuous washing intraperitoneal chemotherapy group(7 mice) and the control group(6 mice).All the mice were killed after two courses of treatment and the weight and volume of the cavity tumor were examined. The cell cycle expresstion rate of C erbB2 and Fas of abdominal neoplasms tissues in washing liquid were detected with FCM. Results:In the intraperitoneal washing group,the nude mice's FBW/IBW was 0.886. The volume of the cavity tumor is obviously smaller than the routine group. Significant difference in tumor growth inhibition rate was found between the routine group and the washing group.In the washing liquid, G 1 and S phase ratios were markedly lower ( P 0.05); C erbB2 rates were 66%、59% and 42% in control、common and washing group respectively, which was significant different between all groups ( P
