Abstract:Objective To evaluate the clinical effect of Pemetrexed in the treatment of recurrent ovarian cancer. Methods Ninety cases of recurrent ovarian cancer patients, who were treated in the Affiliated Hospital of Nantong University from January 2013 to December 2014, were selected as the research objects and randomly divided into control group (40 cases) and observation group (50 cases). The control group was given Paclitaxel combined with Irinotecan therapy, and the observation group received Pemetrexed therapy. The clinical therapeutic effect and ascites control rate were compared between the two groups. Results In the observation group, the total effective rate was 66.0%, the ascites control rate was 82.0%; in the control group,the total effective rate was 35.0%, the ascites control rate was 47.5%, the differences between the two groups were statistically significant (p < 0.05). The incidence of adverse reactions was 38.0% in the observation group and 42.5% in the control group, there was no statistical difference between the two groups (p > 0.05). There were statistical differences in post-treatment levels of CA125, TNF-α, SIL-2r and HE4 between the two groups (p < 0.05). Conclusions In clinical treatment of recurrent ovarian cancer, Pemetrexed has good curative effect and high safety. It is worthy of promotion.
