Methods= The serum CA724 level was determined by electrochemiluminescence immunoassay, while the objective response rate (eRR) was assessed according to response evaluation criteria in solid tumors (RECIST). The association of the changes of serum concentration of CA724 with eRR was analyzed. Results: The eRR in CA724 (pretreatment serum level) high and low groups was 32.3% (20/62) and 52.8% (19/36), respectively (P=0.045). The relationship between the reduction of CA724 and the eRR was statistically significant (P=0.044). Receiver operating characteristic (ROC) curve established the best cutoff value of the decrease ratio of CA724 as 20.5%. Conclusions: CA724 decline seems to indicate chemotherapy efficacy in patients with advanced GC, and an average drop of 20.5% in serum CA724 appears to predict the sensitivity to chemotherapy.展开更多
