Apatinib for elderly patients with advanced or metastatic GC - Video abstract [ID 322710]

Описание: Video abstract of a clinical trial report paper "Efficacy and safety of apatinib for elderly patients with unresectable advanced or metastatic gastric cancer: a multi-centre, single-arm, phase II study" published in the open access journal OncoTargets and Therapy by Dengfeng Ren, Guoxiu Wang, Yu Zhang et al.

Background: Apatinib improves progression-free survival and overall survival with an acceptable safety profile in Chinese patients with chemotherapy-refractory advanced or metastatic gastric cancer. However, the efficacy and safety of apatinib are unclear for elderly patients. This study was undertaken to prospectively investigate the efficacy and safety of apatinib for elderly patients with unresectable advanced or metastatic gastric cancer, who experienced progression to at least one lines of chemotherapy.

Methods: This open-label, single-arm, phase II study enrolled patients aged ≥ 60 years with advanced gastric cancer, who experienced progression to one or more lines of chemotherapy at five centers in China. Patients received apatinib in an oral dose of 500mg or 250mg daily according to the research physicians’ decision. The primary end point was progression-free survival, and the secondary end points were objective response rate, disease control rate, overall survival, and safety.

Results: Forty-eight patients were enrolled between June 2017 and September 2019. The median age was 65.5 years (range 60– 80 years). Twenty-seven patients (56.3%) started treatment with an initial dose of 500 mg and 21 patients (43.7%) with 250 mg. The median progression-free survival and overall survival were 3.00 months (95% confidence interval, 2.17– 3.84) and 8.10 months (95% confidence interval, 4.35– 11.85), respectively. The objective response rate and disease control rate assessed by the investigators were 16.7% and 72.9%, respectively. The common side effects were fatigue (58.3%), hypertension (47.9%), abdominal pain (33.3%), proteinuria (29.2%), leukopenia (22.9%), and neutropenia (20.8%). Hypertension (22.9%) was the major grade 3/4 toxicity.

Conclusion: These data suggest that apatinib is effective and relatively tolerable for elderly patients with unresectable advanced or metastatic gastric cancer who have received at least first-line chemotherapy.
