[Pathological Findings of Chronic Effects Observed in the Kidneys Exposed to Antineoplastic Agents in Two Adolescent Patients].

Cisplatin and ifosfamide are well-known nephrotoxic agents that can cause acute and chronic glomerular and/or tubular toxicity. We examined 2 adolescent patients who were receiving cisplatin and ifosfamide treatments. Pathological findings of patient 1 showed acute tubular necrosis-like patchy injury. Tubulointerstitial nephrosis and glomerular sclerosing were revealed in patient 2. These findings were consistent with the known damages induced by cisplatin and ifosfamide. Proteinuria and mild decline of eGFR were noticed after more than 10 months after the completion of the treatment. It is important to monitor such consequences in long-term follow up. Adult based medical services are required for childhood and adolescent cancer survivors.
