The purpose of our study was to determine the most accurate analytic method to
define in vitro chemosensitivity, using clinical response as reference standard in
prospective clinical trial, and to assess accuracy of adenosine triphosphate-based
chemotherapy response assay (ATP-CRA). Forty-eight patients with chemo-na?e,
histologically confirmed, locally advanced or metastatic gastric cancer were enrolled
for the study and were treated with combination chemotherapy of paclitaxel 175
mg/m2 and cisplatin 75 mg/m2 for maximum of six cycles after obtaining specimen
for ATP-CRA. We performed the receiver operator characteristic curve analysis
using patient responses by WHO criteria and ATP-CRA results to define the method
with the highest accuracy. Median progression free survival was 4.2 months (95%
confidence interval [CI]: 3.4-5.0) and median overall survival was 11.8 months (95%
CI: 9.7-13.8) for all enrolled patients. Chemosensitivity index method yielded highest
accuracy of 77.8% by ROC curve analysis, and the specificity, sensitivity, positive
and negative predictive values were 95.7%, 46.2%, 85.7%, and 75.9%. In vitro
chemosensitive group showed higher response rate (85.7% vs. 24.1%) (P=0.005)
compared to chemoresistant group. ATP-CRA could predict clinical response to
paclitaxel and cisplatin chemotherapy with high accuracy in advanced gastric cancer
patients. Our study supports the use of ATP-CRA in further validation studies.| 번호 | 참고문헌 | 국회도서관 소장유무 |
