A phase II study of preoperative DOS for cStage III gastric cancer

Phase 2
Conditions
Gastric cancer
Registration Number
JPRN-jRCTs051180086
Lead Sponsor
Kurokawa Yukinori
Brief Summary

The primary endpoint, the 3-year progression-free survival rate, was 54.2% (80% CI, 52.2%-70.8%; 95% CI, 41.8%-70.3%), and the lower limit of the 80% confidence interval exceeded the 50% threshold. This showed a statistically significant difference. There were no major safety issues, and preoperative DOS therapy was considered to be a promising treatment regimen for cStage III gastric cancer and esophagogastric junction cancer.
