Validation of Treatment Efficacy of a Computer-assisted Program for Breast Cancer Patients receiving Postoperative Adjuvant Chemotherapy

Aim: To validate the clinical value of a computer assisted program (CAP), (visit website; http://xinenhuang.blog.sohu.com for details) for breast cancer patients who receive postoperative adjuvant chemotherapy.
Methods: Patients with histologically confirmed breast cancer after mastectomy who received postoperative chemotherapy in Jiangsu Cancer Hospital and Research Institute were recruited in this study. All eligible patients are divided into three groups: group A, regimen of practical chemotherapy consistent with CAP prediction; group B, partly consistent with CAP prediction; group C, inconsistent with CAP prediction. Overall survival (OS) was compared among groups A, B and C to determine the efficacy of CAP.
Results: From November 1992 to July 2007, 310 female breast cancer patients were recruited into this study, with 112, 106 and 89, respectively, in groups A, B, and C. Prognosis of group A was better than both group B and C, with significantly different survival curves between group A and B (p=0.0004) and group A and C (p=0.0046).
Conclusion: Validation showed our CAP to provide clinically valuable information on adjuvant chemotherapy for postoperative breast cancer patients.
