A pCR following preoperative docetaxel/platin/fluoropyrimidine indicates favorable outcome in patients with gastric or EGJ adenocarcinoma. Tumor location in the EGJ is associated with a higher pCR rate.
Background:No comparisons of different doses of docetaxel-capecitabine in patients with advanced gastric cancer have been performed.Methods:Patients with previously untreated metastatic/locally advanced gastro-oesophageal or gastric adenocarcinoma were enrolled in a prospective multicentre phase II trial. Two sequential cohorts received docetaxel 75 mg m−2 (day 1) plus capecitabine 1000 mg m−2 twice daily (days 1–14) (cohort I) or docetaxel 60 mg m−2 (day 1) plus capecitabine 800 mg m−2 twice daily (days 1–14) (cohort II) every 3 weeks. The primary end point was confirmed overall response rate.Results:In all, 91 patients were enrolled (cohort I, n=40; cohort II, n=51) and 87 were evaluable for efficacy (n=38, 49, respectively). Overall response rate was 50.0% in cohort I and 23.5% in cohort II (exploratory analysis, P=0.014). Median times to tumour progression and overall survival were 5.6 and 10.1 months in cohort I and 3.7 and 7.2 months in cohort II, respectively. Dose reductions for docetaxel and capecitabine were required in 50.0% and 57.5% of patients in cohort I and 11.8% and 15.7% in cohort II, respectively.Conclusion:Starting treatment with full doses and reducing promptly seems to be the more promisingly effective strategy than starting cautiously with lower doses. Docetaxel/capecitabine 75/2000 mg m−2 is a manageable, convenient outpatient combination with promising efficacy against advanced gastric cancer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
