Abstract ObjectiveTo evaluate the difference in the efficacy and adverse reactions of application of Oxaliplatin plus S-1 and Gemcitabine plus Cisplatin in treatment of advanced triple negative breast cancer.MethodsAltogether 76 cases of untreated triple negative breast cancer patients with Eastern Cooperative Oncology Group(ECOG)score≤1 were treated from January 2012 to January 2015 in our hospital were randomly divided into SOX Group(38 cases)and GP Group(38 cases).Two groups were treated with Oxaliplatin plus S-1 and Gemcitabine plus Cisplatin respectively for at least 8 cycles(21 days as a cycle)so as to compare the clinical response rate(RR),overall survival(OS),progression free survival(PFS)and adverse reactionsabove GradeⅢof two groups.ResultsThe median follow-up time of the two groups was 22.4(18.2-25.7)months and 23.3(17.8-24.9)months respectively,the total RR and disease control rate(DCR)of SOX Group were 57.89%(22/38)and 76.32%(29/38)respectively in contrast with GP Group′s 63.16%(24/38)and 73.68% (28/38);no significant difference was seen between OS of two groups[HR=0.93,95%CI(0.65,1.36),P<0.05];the PFS of GP Group was significantly higher than that of SOX Group[HR=0.71,95%CI(0.53,0.92),P>0.05].No statistically significant difference was found in the incidence of adverse reactions above GradeⅢbetween the two groups(P>0.05).ConclusionAlthough Gemcitabine plus Cisplatin shows priority over Oxaliplatin plus S-1 in progression free survival time,no significant difference has been seen in the total survival time and incidence of adverse reactions above GradeⅢ between two regimens.Both of the two regimens are safe and effective in treatment of advanced triple negative breast cancer.
