ARTICLE HIGHLIGHTS
Research background
Patients with digestive obstruction generally have advanced gastric cancer, affecting their quality of life and survival.
Research motivation
Existing methods cannot relieve digestive obstruction very well.
Research objectives
Continuous gastric artery infusion chemotherapy (cGAIC) was effective and safe in relieving digestive obstruction.
Research methods
Twenty-nine patients with digestive obstruction of advanced gastric cancer treated by cGAIC were reviewed retrospectively. Interventional treatments combined with C-arm computed tomographic angiography were performed to accurately infuse oxaliplatin into the tumor-feeding artery. Radiology responses, Stooler’s Dysphagia Score and toxic effects were evaluated.
Research results
The overall response rate was 89.7% after cGAIC. The postoperative Stooler’s Dysphagia Score was significantly reduced. Twenty-two (75.9%) of the 29 patients experienced relief of digestive obstruction after the first two cycles, and 13 (44.8%) initially unresectable patients were then considered radically resectable. The median overall survival time was 16 mo.
Research conclusions
The efficacy and safety of cGAIC in relieving digestive obstruction were demonstrated, and cGAIC could improve radical resection after cGAIC and survival time. Intraoperative CACTA can help with precise definition of the perfusion area.
Research perspectives
To improve the efficacy of chemotherapy using interventional methods.
