Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults aged 18-75 with histologically confirmed locally advanced gastric carcinoma and an ECOG score of 0-1.

Probably not a fit

Patients who cannot undergo surgical procedures or have HER2 overexpression may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial aims to evaluate the efficacy and safety of a novel neoadjuvant chemotherapy approach using arterial infusion of oxaliplatin combined with S-1, compared to the conventional SOX regimen for patients with locally advanced gastric cancer. Participants will be randomly assigned to receive either treatment for three cycles, followed by surgical resection and additional adjuvant chemotherapy. The study seeks to determine if the arterial infusion method provides better outcomes than traditional intravenous administration. The trial will also assess major pathological responses to the treatments.

Why it matters

Potential benefit: If successful, this study could offer a more effective neoadjuvant treatment option for patients with locally advanced gastric cancer.

How similar studies have gone: While there have been studies on neoadjuvant chemotherapy for gastric cancer, the specific approach of arterial infusion combined with S-1 is relatively novel and has not been extensively tested.
