[Associations between Clinical Factors and Acute Renal Failure Due to Cisplatin Combination Chemotherapy for Lung Cancer].

In this study, we investigated the clinical factors associated with acute kidney injury (AKI) due to combination therapy with cisplatin (CDDP) for treating lung cancer. We classified cases according to the presence or absence of adequate hydration and magnesium(Mg)administered above the regulations of the registered regimen to evaluate the effect due to differences in hydration on AKI. We also investigated clinical factors before and after administration of CDDP in each case group, and examined their association with AKI. Seventy-four patients with lung cancer that were indicated for treatment with a CDDP combination regimen between December 2012 and April 2013 were studied. The patients whose conditions progressed to AKI of Bgrade 2 accounted for 0% (0/33) in the Mg administration group and 7.3%(3/41)in the Mg non-administration group. In particular, 2 cases of serious AKI (grade 4) were observed in the Mg non-administration without additional hydration group. When compared with other groups, a high antiemetic rate and favorable urine volume were observed in the Mg administration with additional hydration group. In the patients with AKI, many developed hyponatremia of Bgrade 3 within 1 week after administration of CDDP. Although Mg administration and ample hydration seem to be effective measures to deal with CDDP-caused AKI, comprehensive monitoring, including antiemesis therapy, after CDDP administration and correction of electrolytes is important.

[Risk factors for cardiotoxicity during fluorouracil and cisplatin combination chemotherapy].

We investigated the incidence of cardiovascular symptoms in patients treated with fluorouracil and cisplatin (FP) combination chemotherapy. Between April 2010 and March 2011, 61 patients were treated with FP therapy at the Department of Gastroenterology, Niigata Prefectural Cancer Center Hospital. Within 1 week of treatment and within the first or second course of therapy, six patients developed chest pain. To investigate the risk factors for cardiotoxicity following FP therapy, patients were divided into cardiotoxicity incidence and non-incidence groups. The prevalence of diabetes, hypertension, and heart disease was not significantly different between the two groups. Furthermore, serum sodium and potassium levels were not altered following FP therapy. Therefore, no definitive risk factors for cardiotoxicity were identified. These results suggest that while FP chemotherapy-induced nausea, vomiting, and renal damage are serious adverse effects, further attention should also be paid to the potential cardiotoxic effects of FP therapy.
