Perioperative albumin-bound paclitaxel plus SOX chemotherapy with sintilimab for HER2-negative hepatoid stomach cancer
Official title: Prospective, Single-arm, Single-center Phase II Clinical Study of Perioperative Therapy for Locally Advanced HER2-negative Hepatoid Adenocarcinoma of Stomach
Run by Peking University Cancer Hospital & Institute · NCT07178340 · Data updated 2026-11-12
This trial will try giving pre- and post-surgery chemo (albumin-bound paclitaxel and SOX) together with the immunotherapy drug sintilimab to people with locally advanced HER2-negative hepatoid stomach cancer to see if it shrinks tumors and improves outcomes.

Is this trial a fit for you?
✓Likely a good fit
Adults with histologically confirmed hepatoid adenocarcinoma of the stomach that is HER2-negative (IHC 0), clinical stage II–III, fit for perioperative therapy and R0 resection, and with ECOG performance 0–1 are ideal candidates.
✕Probably not a fit
Patients with HER2-positive tumors, metastatic disease, dMMR/MSI-H status, poor performance status, prior anti-tumor systemic therapy, or other active malignancies are unlikely to benefit from this perioperative regimen.
A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.
What this trial studies
Patients with locally advanced (stage II-III) HER2-negative hepatoid adenocarcinoma of the stomach will receive four cycles of preoperative therapy combining albumin-bound paclitaxel, SOX (oxaliplatin plus tegafur/gimeracil/oteracil), and the PD-1 inhibitor sintilimab. If tumors are resectable, radical surgery is planned about 4–6 weeks after the preoperative treatment, followed by adjuvant therapy with the chemotherapy regimen. The trial will monitor perioperative safety, pathological response, and longer-term outcomes such as recurrence-free survival. Key enrollment criteria include HER2 IHC 0, ECOG 0–1, and an expectation of R0 resection, while patients with dMMR/MSI-H, prior systemic therapy, or other active malignancies are excluded.
Why it matters
Potential benefit: If successful, this approach could increase tumor shrinkage before surgery and reduce recurrence risk, improving long-term outcomes for this aggressive gastric cancer subtype.
How similar studies have gone: Combining PD-1 inhibitors with chemotherapy has shown benefits in some gastric cancers, but applying this perioperative combination specifically to HER2-negative hepatoid adenocarcinoma is largely novel and not yet proven.
