ABSTRACT
UNLABELLED: Surgical cytoreduction combined with intraperitoneal chemo-hyperthermia (HIPEC) has shown to provide survival benefits in the management of some peritoneal carcinomatosis. The cisplatin (CP) used in HIPEC carries a risk of renal impairment (RI). This risk could be reduced by administration of amifostine (A). The aim of our study was to assess the utility of A in preventing RI during IPCH with CP. PATIENTS AND METHODS: Retrospective study including patients who underwent HIPEC between January 2007 and June 2013. The HIPEC involved administration of CP and mitomycin C, between 41 and 43 °C. The peri-anaesthetic management was consistent to use A after 2010. Renal function was assessed from the measured creatinine clearance (CreatCl) and the change between D0 and D4 was compared between patients who received A (group A+) and those who did not (group A-). Severe RI was defined as the development of a CreatCl of <30 ml/min. The statistical analysis used a Student t-test and Fischer's exact test. A p-value of <0.05 was deemed to be statistically significant. RESULTS: Over the studied period, seventy five patients underwent HIPEC and the findings from fifty two patients were analysed: thirty one in group A+ and twenty one in group A-. The change in mean CreatCl from D0 to D4 did not differ between the two groups although between D1 and D4 a significantly higher percentage of severe RI was seen in group A-. CONCLUSIONS: This study has shown A to offer benefit in terms of reducing severe RI when CP is used in HIPEC. These results, however, will need to be confirmed in prospective series on larger numbers of patients.
