Risk and impact of delayed renal impairment in patients with locally advanced head and neck squamous cell carcinoma receiving chemoradiotherapy with cisplatin.
Abstract
An incidence of cisplatin-induced acute kidney injury (AKI) of 34% has been reported in patients with locally advanced head and neck squamous cell carcinoma (LA-HNSCC). However, delayed cisplatin-induced nephrotoxicity and long-term renal outcomes remain poorly studied. Patients with LA-HNSCC who underwent definitive or postoperative cisplatin-based chemoradiotherapy (CRT) were included. Acute kidney disease (AKD) was defined as newly developed estimated glomerular filtration rate (eGFR) < 60 ml/min/1.73 m2 for < 3 months, ≥ 35% decrease in eGFR, or > 50% increase in serum creatinine for <3 months from baseline. A total of 509 patients were analyzed. AKD and AKI occurred in 27.9% and 13.4% of patients, respectively. Most patients had primary prophylactic feeding tube (95%) and definitive CRT (83%). More AKD patients had an ECOG status of 0 (p = 0.017), diabetes (p = 0.044), and hypertension (p < 0.001). AKI, but not AKD, was significantly associated with cumulative cisplatin dose, delay, dose reduction, termination, and hospitalization during CRT. GFR percentage in patients with AKD declined significantly during CRT (- 36%), worsened at 3 months (- 39%), and had not recovered to baseline at 12 months after CRT (- 29%).
