To evaluate the efficacy and safety of capecitabine in patients with advanced or recurrent gastric cancer, we conducted a pilot phase II study in Japan.
Patients with advanced or recurrent gastric cancer were given oral capecitabine 828 mg/m(2) twice daily for 3 weeks, followed by 1 week of no treatment. Two or more cycles were administered. From July 1996 to December 1997, 32 patients were enrolled in the study. The response to capecitabine was evaluated in 31 patients, excluding 1 found to be ineligible.
The overall response rate was 19.4% (6/31, 95% confidence interval: 7.5-37.5%). The median duration of response was 124.5 days, the median time to disease progression 85.0 days, and the median survival time 247.5 days. Drug-related adverse events of grade 3 or higher were infrequent: in 2 patients (6.3%) total bilirubin concentration increased, and 1 patient (3.1%) each had elevation of GOT, anemia, lymphopenia, increased creatinine, and hand-foot syndrome. No patient had gastrointestinal toxicity of grade 3 or higher.
Capecitabine was suggested to be safe and effective in the treatment of advanced or recurrent gastric cancer. Further phase II studies of capecitabine on a large scale are warranted.
为评估卡培他滨对晚期或复发性胃癌患者的疗效和安全性,我们在日本开展了一项II期预试验研究。
晚期或复发性胃癌患者口服卡培他滨828 mg/m²,每日2次,共3周,随后1周不进行治疗。给予两个或更多周期的治疗。1996年7月至1997年12月,32例患者入组本研究。对31例患者评估卡培他滨的疗效,排除1例不符合条件的患者。
总缓解率为19.4%(6/31,95%置信区间:7.5 - 37.5%)。中位缓解持续时间为124.5天,疾病进展的中位时间为85.0天,中位生存时间为247.5天。3级或更高等级的药物相关不良事件很少见:2例患者(6.3%)总胆红素浓度升高,1例患者(3.1%)分别出现谷草转氨酶升高、贫血、淋巴细胞减少、肌酐升高和手足综合征。没有患者出现3级或更高等级的胃肠道毒性。
卡培他滨在治疗晚期或复发性胃癌方面显示出安全有效。有必要进一步大规模开展卡培他滨的II期研究。
