Abstract

Poorly differentiated neuroendocrine carcinoma has a poor prognosis, especially when associated with distant metastasis. A 60-year-old man was admitted to a private hospital because of dyspnea at work in 2007. Computed tomography revealed lung infarction and a right adrenal tumor sized 12 cm in diameter that was tightly compressed against the inferior vena cava (IVC). Moreover, multiple lymph node metastases around the celiac axis and a solitary liver metastasis at the lateral segment were observed. Thus, we planned chemotherapy without surgery. We selected a combination therapy of irinotecan (CPT-11) and cisplatin (CDDP) (i.e., IP therapy): administration of CDDP [60 mg/m2 body surface area (BSA)] on day 1 plus CPT-11 (80 mg/m2) BSA on days 1 and 8. Thereafter, this protocol was repeated at 3-week intervals. After 15 months of this chemotherapy strategy, the whole lesions showed a partial response by RECIST. The primary tumor had shrunk to 4.2 cm in diameter. In November 2008, we planned surgery to perform resection of the whole lesions. Histological diagnosis of the specimen was a poorly differentiated neuroendocrine carcinoma based on the immunostaining features, i.e., synaptophysin- and chromogranin positive. There were no viable tumor cells at the dissected lymph nodes or at the liver tumor. After surgery, CPT-11 administration was continued. The patient has remained well for 9 months without recurrence.
