Summary
Although there has been some progress in chemotherapy for metastatic gastric cancer, no standard regimen of adjuvant chemotherapy is available, and many clinical trials have produced contradictory results. The majority of randomized clinical trials studying adjuvant chemotherapy in gastric cancer have been underpowered, involved low-volume centers, or used ineffective chemotherapy regimens. As a result, well-designed multicenter trials are still needed. The ACTS-GC trial, which demonstrated the efficacy of S-1 for stage II-III gastric cancer patients who underwent curative resection with extended lymph-node dissection (D2), may be valid in countries where D2 surgery is considered the standard of care. S-1 improved the 3-year overall survival from 70.1% for surgery alone to 80.1%. However, 3-year overall survival in stage IIIA and stage IIIB patients receiving S-1 were 77.4% and 63.4%, respectively, which are less satisfactory compared to the rate for stage II (90.7%). Based on the unsatisfactory outcome among later stage patients in the ACTS-GC adjuvant trial, further investigation is needed for more effective postoperative treatment of patients with stage IIIB and IV (M0) cancer. Therefore, the researchers investigated the efficacy and safety of S-1 versus S-1 plus cisplatin as adjuvant chemotherapy in patient with curatively resected gastric adenocarcinoma.
Detailed Description
This controlled study is designed to evaluate the efficacy of S-1 on survival compared with S-1 plus cisplatin. Patients will be randomly assigned to receive either surgery followed by treatment with S-1 plus cisplatin or surgery followed by treatment with S-1 within 42 days after curative resection. To assess the efficacy, data on recurrence and survival will be collected from the time of enrollment until 5 years after surgery. To evaluate safety, data on adverse events will be collected from the time of enrollment until 1 year after surgery.
Criteria for eligibility

Minimum Age: 18 Years
Gender: Both
Criteria: Inclusion Criteria:

1. 18-70 years

2. Histologically proven adenocarcinoma of the stomach

3. Curative D2 lymphadenectomy resection for gastric cancer, who can be randomized to either study arm within 6 weeks after surgery

4. Stage II, III and IV (M0)(AJCC 7th edition)

Exclusion Criteria:

1. Pregnant or lactating women.

2. Women of childbearing potential with either a positive or no pregnancy test at baseline. Postmenopausal women must have been amenorrheic for at least 12 months to be considered of non-child bearing potential.

3. Sexually active males and females (of childbearing potential) unwilling to practice contraception during the study.

4. Any evidence of metastatic disease (including presence of tumor cells in the ascites).

5. Previous cytotoxic chemotherapy, radiotherapy or immunotherapy except corticosteroids, for the currently treated gastric cancer.

6. Major surgery within 4 weeks prior to study treatment start, or lack of complete recovery from the effects of major surgery.

7. History of another malignancy within the last five years except cured basal cell carcinoma of skin and cured carcinoma in-situ of uterine cervix.

Clinically significant (i.e. active) cardiac disease e.g. symptomatic coronary artery disease, New York Heart Association (NYHA) grade II or greater congestive heart failure or serious cardiac arrhythmia requiring medication or myocardial infarction within the last 12 months.

8. Lack of physical integrity of the upper gastrointestinal tract or those who have malabsorption syndrome likely to influence absorption of capecitabine, or inability to take oral medication.

9. Organ allografts requiring immunosuppressive therapy.

10. Serious uncontrolled intercurrent infections or other serious uncontrolled concomitant disease.

11. Prior unanticipated severe reaction to fluoropyrimidine therapy (with or without documented dihydropyrimidine dehydrogenase (DPD) deficiency) or patients with known DPD deficiency.

Hypersensitivity to platinum compounds or any of the components of the study medications.

12. Received any investigational drug or agent/procedure, i.e. participation in another trial, within 4 weeks before randomization.

13. Blood transfusions or growth factors to aid hematologic recovery within 2 weeks prior to study treatment start.

14. Requirement for concurrent use of the antiviral agent sorivudine (antiviral) or chemically related analogues, such as brivudine.
