Single-agent Xeloda in the treatment of recurrent and metastatic breast cancer / 中华肿瘤杂志

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy and adverse reactions of Xeloda in the treatment of recurrent and metastatic breast cancer.</p><p><b>METHODS</b>This clinical study was designed to treat 69 patients with recurrent and metastatic breast cancer with Xeloda, 2500 mg/m(2)/d, twice daily for 2 weeks followed by a 1-week rest period, repeated every 3 weeks.</p><p><b>RESULTS</b>Sixty-nine patients received Xeloda for more than 1 cycle. The overall response rate (CR + PR) was 16.0%, clinical benefit rate (CR + PR + SD > or = 24 months) was 27.5%, disease control rate (CR + PR + SD) was 75.4%. The median time to failure (TTF) was 3 months (range: 0.7 - 11 months). The median time to progression (TTP) was 2 months (range: 0.7 - 11 months). The median duration of response (CR + PR) was 6 months (range: 4 - 11 months). The most common treatment-related adverse events were hand-foot syndrome (HFS) that occurred in 60.8% (42/69) patients mostly as grade I-II. Fifty-five percent (22/40) of patients who had received high dose preventive Vit B6 developed HFS without grade III; while 69% (20/29) of patients who had not received such treatment did develop HFS including 2 patients with grade III. However, there was not significant difference between the two groups.</p><p><b>CONCLUSION</b>Xeloda is an effective and well tolerated treatment in patients with recurrent and metastatic breast cancer. The symptoms of HFS may be relieved by high dose Vit B6 as prevention.</p>
