Basic Trial Information

Phase	Type	Status	Age	Sponsor	Protocol IDs
Phase II	Treatment	Closed	20 and over	Other	KYUH-UHA-GC03-01 NCT00088816

Objectives

Primary

1. Determine the efficacy and feasibility of neoadjuvant chemotherapy comprising S-1 and cisplatin in patients with stage IV gastric adenocarcinoma.
2. Determine the overall survival of patients treated with this regimen.

Secondary

1. Determine the time to progression and types of initial recurrence in patients treated with this regimen.
2. Determine tumor response in patients treated with this regimen.
3. Determine mortality and morbidity related to treatment in these patients.
4. Determine the toxicity of this regimen in these patients.

Outline

This is a multicenter study.

Patients receive oral S-1 on days 1-21 and cisplatin IV over 2 hours on day 8. Treatment repeats every 35 days for 2 courses in the absence of disease progression or unacceptable toxicity. Patients then undergo gastrectomy with lymphadenectomy. Patients resume oral S-1 after surgery.
