BACKGROUND: Vascular endothelial growth factor (VEGF) inhibitors are associated with a high incidence of proteinuria. In patients with diabetes, increased proteinuria is closely associated with decreased renal function; however, the impact of increased proteinuria on renal function in patients with cancer and diabetes mellitus undergoing VEGF inhibitor therapy remains unknown.
METHODS: The incidence of proteinuria and renal function in patients with cancer and a history of diabetes who were treated with VEGF inhibitors at the National Cancer Center Hospital East between January 2018 and December 2019 was retrospectively investigated.
RESULTS: Among the 49 patients included, 21 (43%) developed proteinuria ≥ 3 + after VEGF inhibitor treatment. In all patients, a decreasing trend in the estimated glomerular filtration rate (eGFR) was observed beginning 2 years after treatment initiation. The decrease in eGFR from baseline was - 6.6% at 1 year, -11% at 2 years, and - 13% at 4 years. Patients who developed proteinuria ≤ 2 + showed no significant decrease in eGFR from baseline to either the end of treatment (p = 0.91) or the latest value during the observation period (p = 0.64). Similarly, no significant decrease in eGFR was observed in those with proteinuria ≥ 3+ (end of treatment, p = 0.91; latest value during the observation period, p = 0.18).
CONCLUSIONS: In patients with cancer and diabetes mellitus, increased proteinuria after VEGF inhibitor therapy suggested that it was not associated with a significant decline in renal function.
