A Recombinant Human Adenovirus Type 5 (H101) Combined With Chemotherapy for Advanced Gastric Carcinoma: A Retrospective Cohort Study

BACKGROUND: This retrospective cohort study aimed to evaluate the clinical outcomes of H101 combined with chemotherapy for advanced gastric carcinoma (GC) patients. METHODS: The advanced GC patients, who were treated with H101 and/or chemotherapy, were enrolled and divided into three groups according to treatment method. The clinical characteristics of patients, clinical short-term and long-term outcomes, followed up, and complication were analyzed. RESULTS: A total of 95 patients (30 patients in group A were treated with H101, 33 in group B patients were treated with chemotherapy, 32 patients in group C were treated with H101 combined with chemotherapy) were retrospectively reviewed. The disease control rate (DCR) and overall response rate (ORR) were significantly greater in group C (81.3% and 50.0%) than in groups A (63.3% and 30.0%) and B (66.7% and 33.3%, all p < 0.05). The 1- and 2-year survival rates and progression-free survival were significantly greater in group C than in groups A and B (all p < 0.05). There was no significant difference in complication among the three groups. At dose levels of 0.5 × 10(12) vp/day, 1.0 × 10(12) vp/day, and 1.5 × 10(12) vp/day, complications were not increased as increased of dose. CONCLUSIONS: H101 combined with chemotherapy may be a potential therapeutic option for patients with advanced GC, and prospective studies with proper assessment of toxicity will be needed in the future.
