Abstract:Objective To investigate the efficacy of paclitaxel (PTX) liposome combined with fluorouracil derivatives (S-1) in the treatment of advanced gastric cancer. Methods Totally 97 patients with advanced gastric cancer treated in Zhangjiagang Hospital Affiliated to Soochow University and Zhangjiagang Hospital of Traditional Chinese Medicine, from January 2016 to June 2018, were divided into observation group (n?=?47) and control group (n?=?50) according to the final treatment plan. The observation group was treated with PTX liposome combined with S-1, while the control group was treated with conventional PTX combined with S-1. The curative effect, median progression free survival time and adverse reactions of the two groups were observed. Results There was no significant difference in short-term efficacy between the observation group and the control group (P?>?0.05); the effective rates of the two groups were 44.68% and 46.00% respectively; the median progression-free survival time in the observation group and the control group were 7 months (95% CI: 6.57, 7.43) and 6 months (95% CI: 5.67, 6.33), and the difference was not statistically significant (P?>?0.05); The bone marrow suppression, alopecia and muscle joint pain in the observation group were lighter than those in the control group (P?0.05); There were no significant difference in nausea and vomiting, liver function impairment and peripheral nerve adverse reactions between the observation group and the control group (P?>?0.05). Conclusion PTX liposome combined with S-1 is effective in the treatment of advanced gastric cancer, and has the advantage of mild side effects.
