Abstract

This study aimed to investigate whether renin-angiotensin system inhibitors (RAS‑I) have an advantage over calcium channel blockers (CCB) for suppression of proteinuria in hypertensive patients with gastric cancer receiving ramucirumab (RAM) treatment. Adult Japanese patients with gastric cancer who were outpatients at Asahikawa Medical University Hospital, National Hospital Organization Hokkaido Cancer Center, and Iwate Medical University Hospital between July 1, 2015, and March 31, 2021, were included in this study. Of these patients, those who had received first‑time RAM treatment, and those treated with antihypertensive agents including RAS‑I or a CCB at initial RAM administration were included. A total of 36 patients were analyzed in this study. Of these patients, 17 patients were classified into the RAS‑I group and the remaining 19 into the CCB group. After 12 weeks of RAM administration, the prevalence of proteinuria in the RAS‑I group was significantly lower than that in the CCB group. Additionally, Kaplan‑Meier analysis showed that the cumulative occurrence of proteinuria in the RAS‑I group over 12 weeks following RAM administration was significantly lower than that in the CCB group. Furthermore, simulation of the time course of RAM blood concentrations based on the O'Brien model showed that there may not be differences in the RAM blood concentration profiles over 12 weeks between the two groups. RAS‑I may have an advantage over CCB for suppressing proteinuria in hypertensive patients with gastric cancer treated with blood pressure antihypertensive agents. Our results provide useful information to healthcare professionals involved in the administration of RAM treatment.
