Objectives: We reported that the KDIGO (Kidney Disease: Improving Global Outcomes) criteria could stratify the risk of mortality in acute kidney injury (AKI) caused by cisplatin. The purpose of this study was to investigate risk factors of severe cisplatin-induced AKI (CIA)., Methods: From January 2006 to December 2012, we identified Japanese cancer patients who were treated with cisplatin as a first-line chemotherapy at Nagoya University Hospital. Serum creatinine levels were used to define CIA., Results: We evaluated 1,721 patients treated with cisplatin. In multivariable analysis, cisplatin dosages/m(2) [odds ratio (OR) 1.019] or diagnosis of cancer stage 4 (OR 1.797) were risk factors of moderate CIA. History of diabetes mellitus (OR 3.454), history of cardiovascular disease (OR 3.612) or diagnosis of cancer stage 4 (OR 2.610) were risk factors of severe CIA., Conclusions: Diabetes mellitus, cardiovascular disease and advanced cancer increased the risk of severe CIA. As severe CIA shortens the survival period, we should consider whether the use of cisplatin benefits these patients.

Objectives: The purpose of this study was to investigate if KDIGO (Kidney Disease: Improving Global Outcomes) criteria could be a useful outcome predictor of cisplatin-induced acute kidney injury (CIA)., Methods: In the period between January 2006 and December 2011, we identified Japanese patients who had been diagnosed with cancer and treated with cisplatin as a first-line chemotherapy at Nagoya University Hospital. The serum creatinine was used to define CIA and determine the KDIGO criteria of each patient after chemotherapy within 7 days., Results: Eighty-nine patients (5.4%) were classified as having acute kidney injury (AKI) going by the KDIGO criteria, and the numbers of patients classified into AKI stages 1, 2 and 3 were 65 (3.9%), 18 (1.1%) and 6 (0.4%), respectively. Overall survival times were significantly shorter in AKI stages 2 and 3 than in stage 1. The area under the receiver operating characteristic curve with all patients was 0.68, and that of patients who were diagnosed with cancer stage 4 was 0.80., Conclusion: These results suggest that KDIGO criteria can be a predictor of CIA mortality in patients with different primary cancers., (Copyright © 2012 S.
