The treatment of advanced gastric cancer has been a significant global health problem. With surgery still the backbone, many clinical trials have shown the benefit of perioperative treatment to gastric cancer patients. The neoadjuvant treatment is one of the most important parts.~Besides chemotherapy and chemoradiotherapy, the report of transcatheter arterial infusion (TAI) or transcatheter arterial embolism (TAE) in gastric cancer is relatively limited, though some case reports have showed its efficacy and safety in advanced gastric cancer. The combination of TAI and TAE (TACiE) may be more perspective in the treatment of gastric cancer. With transarterial infusion chemotherapy, TACiE increases the local concentration of chemotherapeutic agents and reduces adverse reaction. With embolization, TACiE blocks the blood supply and causes the necrosis of tumors, in this way exposing tumor antigen and promoting tumor immunity.~Based on those knowledges, we designed this prospective, single-center, single-arm, phase 2 trial to evaluate the feasibility and safety of neoadjuvant transcatheter infusion and embolism (TACiE) in patients with locally advanced adenocarcinoma of stomach and gastroesophageal junction. The primary purpose of this study is to evaluate the pathologic complete response (pCR) rate of TACiE. The second purpose is to evaluate pathologic response rate (pRR), objective Response Rate (ORR), overall survival (OS) and progression-free survival (PFS) of the patients enrolled in this study.
This is a prospective, single-center, single-arm, phase 2 trial to evaluate the feasibility and safety of neoadjuvant transcatheter infusion and embolism (TACiE) in patients with locally advanced adenocarcinoma of stomach and gastroesophageal junction.~The TACiE protocol includes four cycles. Transcatheter oxaliplatin and concurrent embolism on day 1 and oral S-1 on day 1-14 will be administrated in the first and third cycles. Intra-venous oxaliplatin on day 1 and oral S-1 on day 1-14 (SOX) will be administrated in the second and fourth cycles.
