Purpose: Paclitaxel has not been used widely in gastrointestinal cancers. However, a
recent phase II report of paclitaxel in patients with esophageal adenocarcinoma has
suggested a possible role of paclitaxel for the treatment of advanced gastric carcinoma.
A phase II trial was initiated to determine the clinical utility of a 3 drug combination
(paclitaxel, cisplatin, and 5-fluorouracil) in patients with advanced gastric carcinoma.
Materials and Methods: Eligibility included biopsy-proven inoperable or relapsed
adenocarcinoma of the stomach with adequate bone marrow, hepatic, and renal function.
Patients received paclitaxel at 175 mg/m2(3 hour infusion) on day 1
followed by cisplatin at 20 mg/m2/day infusion and 5-fluorouracil at 750
mg/m2/day continuous infusion for 5 days. Treatment has been repeated in
every 4 weeks. Total 31 patients were enrolled; 7 had relapsed disease after resection
and 5-fluorouracil based adjuvant chemotherapy, 5 had previous chemotherapy.
Twenty-one patients had measurable disease and 9 were evaluable. Demographics
included; median age, 47 years(range, 27¡­64 years); male : female, 21:10; median
performance status 2(range, 0¡­4).
Results: Major responses occurred in 16/30(53%; 95% confidence interval, 35¡­71%)
patients(2 complete responses, 14 partial responses); 13 of 21(61.9%) patients with
measurable disease and 3 of 9(33%) evaluable patients. Median response duration was 17
weeks(range, 8¡­44+ weeks) and median time to progression was 20 weeks(range, 8¡­
51+ weeks). Median survival was 27 weeks(range, 8¡­72+ weeks). WHO grade 3¡­4
toxicities included: neutropenia(61.9%), nausea/vomiting(23.8%), mucositis(19%), and
diarrhea(9.5%). Grade 2¡­3 neurotoxicity, fluid retention syndrome, hypersensitive
reaction had occurred in 6, 2, and 1 patients, respectively. There was 1 instance of
treatment-related death due to sepsis.
Conclusion: This regimen was highly active in advanced gastric carcinoma and had
moderate toxicity. However, the response duration was short like other regimens.
Considering poor performance status of our patients, this regimen may have strong
potential in the neoadjuvant setting.
