Abstract:
Objective To study the effect and toxicity of COX-2 selective inhibitor, celecoxib, plus doxetaxel + epirubicin regimen for LABC as neoadjuvant chemotherapy. Methods 59 women with LABC staged ⅡB～ⅢB were allotted and randomly divided into 2 groups: the control group consisted of 29 patients and with the dosage: doxetaxel (75 mg/m2, d1), epirubicin(75 mg/m2, d1) every 3 weeks; the experiment group consisted of 30 patients and with the dosage: doxetaxel (75 mg/m2, d1), epirubicin(75 mg/m2, d1) and celeeoxib (40Omg, twice daily, d1～21) every 3 weeks. After 2 cycles, the efficacy and toxicity of each group were evaluated. Results The control group achieved an overall response rate (RR) of 72.41%(21/29), and consisted of clinical complete remission (cCR) 2 cases, partial remission (PR) 19 cases, stable disease (SD) 8 cases; the experiment group achieved a RR of 80.00 %(24/30), and consisted of eCR 3 cases, PR 21 cases, SD 6 cases. Both of the group had no pathological complete remission (pCR) and progressive disease (PD) case, and the difference of RR between 2 groups showed no statistical signifieance(χ2=0.469, P=0.493). There was no difference of the diameter of tumor between 2 groups before neoadjuvant ehemotherapy(t=0.569, P= 0.570), but showed statistieal significance after neoadjuvant chemotherapy (t=7.300, P=0.000). Incidence of myalgia and arthralgia of the experiment group was lower than that of control group and had statistical significance (P=0.013). Conclusion Doxetaxel plus epirubiein regimen is effective for LABC with tolerable toxicity. Celeeoxib can enhance the effect and reduce the incidence of myalgia and arthralgia.
