    Abstract:
    BACKGROUND: To analyze the clinical outcomes of the irinotecan plus nedaplatin (IN) regimen in patients with advanced germ cell tumors (GCTs) refractory to cisplatin-based combination chemotherapies. METHODS: This study included a total of 20 consecutive advanced GCT patients who were categorized into intermediate- or poor-risk GCT groups according to the International Germ Cell Consensus Classification, and were judged to show refractory or relapsed disease after bleomycin, etoposide and cisplatin and cisplatin, ifosfamide and paclitaxel therapies. All 20 patients subsequently received IN therapy (irinotecan 100 mg/m(2) on days 1 and 15; nedaplatin 100 mg/m(2) on day 1) every 4 weeks. RESULTS: Following a median of 3 cycles of IN, 9 patients (45 %) achieved normalization of serum tumor markers. In addition, surgical resection of the residual tumors following IN was performed in 5 patients, of whom 4 were pathologically diagnosed with no viable cancer cells. At a median follow-up of 9 months, 11 patients (55 %) were alive, including 7 (35 %) with no evidence of disease, whereas the remaining 9 (45 %) died of disease progression. The median duration of overall survival after the introduction of IN to these 20 patients was 13.4 months. Severe hematological toxicities were observed in all patients, but were manageable. Although fatal treatment-related interstitial pneumonia occurred in 1 patient, other non-hematological toxicities were generally tolerable. CONCLUSIONS: Considering the markedly unfavorable characteristics of the included patients with advanced GCT who were intensively treated with cisplatin-based combination chemotherapies, IN could be regarded as having promising therapeutic activity with an acceptable toxicity profile.
