Title:
1561P - APC mutation (mt.), MYC, and GATA6 amplifications (amp.) were associated with worse survival in HER2-positive advanced gastric cancer patients treated with S-1/capecitabine plus oxaliplatin combined with trastuzumab (T-mab) and nivolumab (N-mab)

Excerpt:
Patients were treated with S-1 80 mg/m2/day or Capecitabine 2000 mg/m2/day on days 1-14 with oxaliplatin 130 mg/m2, N-mab 360mg, and T-mab 8mg/kg for initial treatment, and subsequently with 6 mg/kg on day 1, repeated every 3 weeks....Patients with GATA6 amp. showed significantly shorter PFS (median 5.8 vs 32.0 months, HR 3.53, 95%CI 1.25-9.99, p = 0.011) and OS (median 13.9 months vs not reached, HR 3.74, 95%CI 1.04-13.40, p = 0.030).
Secondary therapy:
oxaliplatin + gimeracil/oteracil/tegafur; capecitabine + oxaliplatin
