What this trial studies

This clinical trial investigates the effectiveness and safety of two chemotherapy regimens for patients with stage II or III gastric adenocarcinoma following D2 surgical resection. Participants will be randomly assigned to receive either S-1 combined with docetaxel or S-1 combined with oxaliplatin. The primary goal is to assess disease-free survival, while secondary outcomes include overall survival, safety, and quality of life. Patients aged 18 to 75 with adequate organ function and specific performance status will be eligible for this study.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 75 with stage II or III gastric adenocarcinoma who have undergone D2 resection.

Not a fit: Patients with a history of other malignancies or those who are pregnant or lactating may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a more effective chemotherapy option for patients with advanced gastric cancer, potentially improving survival rates.

How similar studies have performed: Previous studies have shown promising results with S-1 in combination with oxaliplatin, but the combination with docetaxel is being explored in this novel approach.
