Abstract
BACKGROUND AND AIMS: Cisplatin (CDDP) is used as the first line of treatment for some tumors, but its use may be restricted due to its nephrotoxicity. Carboplatin (CARBO) and oxaliplatin (OXA) are less nephrotoxic alternatives to CDDP. This study has the objective to determine the incidence of acute kidney disease after chemotherapy with CDDP, CARBO, or OXA. METHODS: A clinical study of a retrospective cohort of patients who underwent treatment with CDDP, CARBO, or OXA from January-December 2016. Acute kidney Disease (AKD) was defined as elevated serum creatinine (sCR) levels before and up to 3 months after chemotherapy. Morbidities, type of tumor, and treatment data were recorded. RESULTS: A total of 212 patients aged 55.5 ± 14.0 years were evaluated. Among the comorbidities, 30% had arterial hypertension (AH) and 11% had diabetes, and 18% were treated with CDDP, 41% with CARBO, and 41% with OXA. There was no difference in sCR levels before and after chemotherapy regardless of the chemotherapy used. The prevalence of eGFRs <60 mL/min after chemotherapy was higher in patients with AH and cardiovascular disease (CVD). The incidence of post-chemotherapy AKD was 7.0% (n = 13) and the mortality rate was 38.2%. Survival was lower in patients with AKD (P = .012). CONCLUSIONS: There was a low incidence of AKD among the patients regardless of the chemotherapy used, but the patients with AKD had shorter survival. In addition, the reduction in eGFR after chemotherapy was greater in patients with AH and CVD.
