Abstract
Purpose:
The purpose of this study was to evaluate renal function in lung cancer patients who were administered cisplatin with continuous higher-volume hydration (CH) or a short hydration (SH) regimen.
Methods:
We retrospectively evaluated patients with lung cancer who were treated with chemotherapy regimens including >50 mg/m2 of cisplatin between August 2007 and March 2015. Between August 2007 and December 2012, patients received a continuous higher-volume hydration regimen without magnesium (Mg) supplementation (CH group), and after May 2013, patients received a short hydration regimen with Mg supplementation (SH group). To evaluate the factors influencing serum creatinine (SCr) increase during the first course of cisplatin chemotherapy, univariate and multivariate logistic regression analyses were conducted.
Results:
A total of 122 patients were evaluated, 62 patients in the CH group and 60 patients in the SH group. Grade 1 (National Cancer Institute Common Toxicity Criteria for Adverse Events; version 4.0) or higher SCr increases were more frequently observed in the CH group than in the SH group after the first cycle (P = 0.01, Fisher's exact test) and for all cycles (P = 0.03). Multivariate analysis revealed that short hydration (odds ratio (OR), 0.30; 95% confidence internal (CI) (0.11-0.75), P = 0.01) and estimated creatinine clearance (eCcr) of ≥70 mL/min (OR, 0.25; 95% CI (0.088-0.69), P = 0.008) were associated with a significantly reduced risk for cisplatin-induced grade 1 or higher SCr increase.
Conclusion:
Our study suggested that a short hydration method with Mg supplementation and eCcr of ≥70 mL/min reduced the risk of cisplatin-induced nephrotoxicity.
