title: Managing a locally advanced malignant thymoma complicated by nephrotic syndrome: a case report.
abstract: BACKGROUND
  The management of locally advanced inoperable malignant thymoma is difficult as there are no large randomized clinical trial data to guide treatment. However various case series have shown that malignant thymoma is often a chemosensitive disease. Cisplatin-based chemotherapy has been the gold-standard in the management of these patients. However when thymic cancers are complicated by paraneoplastic syndromes that damage kidney and neurological function, cisplatin use is often contraindicated.
  
  
  METHODS
  We report a case of a 37 year old man with locally advanced malignant thymoma complicated by significant nephrotic syndrome and renal impairment. He responded to a novel combination of carboplatin, epirubicin and cyclophosphamide chemotherapy used as first line therapy.
  
  
  CONCLUSIONS
  The treatment with chemotherapy of locally advanced malignant thymoma complicated by nephrotic syndrome and renal impairment is difficult due to the increase of toxicity. In this case, a novel chemotherapy combination with lesser toxicity was used successfully. In addition this chemotherapy combination did not impede the later use of conventional cisplatin-based chemotherapy. Therefore we suggest a course of carboplatin-based chemotherapy for locally advanced malignant thymoma in patients who are unsuitable for cisplatin.
