Multivariate analysis of risk factors for cisplatin-induced nephrotoxicity in gynecological cancer.

AIM: Risk factors for cisplatin-induced nephrotoxicity (CIN) vary by population. This study aimed to assess risk factors for CIN in patients with gynecological cancer.

METHODS

Patients who underwent cisplatin-based chemotherapy for gynecological cancer between January 2009 and December 2015 at Aichi Medical University School of Medicine were included in this study. CIN was defined according to the 'risk, injury, failure, loss, and end-stage kidney disease' (RIFLE) criteria and classified as either risk (Class R) or injury (Class I). Analyses were performed using univariate and multivariate logistic regression models.

RESULTS

Among 112 patients enrolled, 30 had CIN. Multivariate analysis revealed that hydration with magnesium (odds ratio [OR], 0.223), history of cisplatin use (OR, 4.420), and hypoalbuminemia (OR, 4.170) were risk factors for Class R, and that frequency of cisplatin administration (OR, 5.620) and hydration with magnesium (OR, 0.216) were risk factors for Class I.

CONCLUSION

This study confirmed that hydration without magnesium, history of cisplatin use, frequency of cisplatin administration, and hypoalbuminemia are significant risk factors for CIN.
