Objective:To explore the effects of Oxaliplatin plus S-1(SOX) and Gemcitabine plus Cisplatin (GP) regimens on advanced triple-negative breast cancer patients and its affection on levels of carbohydrate antigen 153(CA153) and carcinoembryonic antigen(CEA). Methods:134 patients with advanced triple-negative breast cancer treated in Yancheng City First People's Hospital from August 2012 to August 2015 were selected, and divided into group A and group B(67 cases in each group). Group A was treated with SOX regimen, and group B was treated with GP regimen. The short term effect, long term curative, adverse reactions,serum CA153 and CEA levels were compared between the two groups. Results:After treatment, the response rate and disease control rate of group A was 35.82% and 68.66%, and group B was 34.33% and 65.67%, the difference was not statistically significant(P>0.05).The median time to progression was 9.7 months in group A and 8.2 months in group B, the difference between the two groups was statistical significantly(P=0.031). The 1-year survival rates was 70.15% in group A and 64.18% in group B, the difference was not statistically significant(P=0.462). The median time to overall survival was 20.1 months in group A and 19.4 months in group B, the difference was not statistically significant(P=0.289). Adverse reactions were similar between the two groups. The incidence of hand-foot syndrome, liver function damage, diarrhea and peripheral nerve toxicity in group A were 44.78%, 46.27%, 40.30% and 58.21%, were significantly higher than those in group B(0, 23.88%, 17.91% and 14.93%), the difference between the two groups was statistically significant(P<0.05). The incidence of skin rash, nausea/vomiting, thrombocytopenia and renal toxicity in group A were 19.40%, 41.79%, 41.79% and 7.46%, were significantly lower than those in group B(37.31%, 70.15%, 65.67% and 28.36%), the difference between the two groups was statistically significant(P<0.05). After treatment,the levels of CA135 and CEA of the two groups were significantly reduced compared with before, the difference was statistically significant(P<0.05). And the levels of CA135 and CEA of two groups had no statistically significant difference after treatment(P>0.05). Conclusion:Both SOX and GP regimens are safe, effective and tolerable in reating advanced triple-negative breast cancer patients. |
