Background: The prognosis of metastatic hepatoblastoma remains poor; to improve it, pulmonary metastasis must be controlled. Indocyanine green (ICG) fluorescent imaging has been used recently for lung metastasectomy. The objective of our study was to clarify the usefulness of ICG imaging for lung metastasectomy of hepatoblastoma using detailed clinicopathological analysis. Procedure: Patients with hepatoblastoma who underwent resection of pulmonary metastases with ICG fluorescent imaging were studied using retrospective analysis of clinical information, a review of their surgical records, and a histological analysis of their metastatic nodules. Results: Sixteen patients were enrolled. In total, 61 ICG-imaging-guided pulmonary metastasectomies were performed, and 350 ICG-positive and 23 ICG-negative specimens were identified. Tumors were confirmed in 250 of the ICG-positive specimens, including eight nonpalpable nodules, on microscopic examination. One hundred ICG-positive specimens and histologically tumor-negative specimens showed histological changes suggesting the regression of a tumor or bloodstream disturbance. The palpable ICG-negative tumors showed more-severe atypia than the ICG-positive tumors. Conclusions: This study demonstrates the high sensitivity of ICG imaging in detecting metastatic lesions of hepatoblastoma. Histological examinations suggested that ICG imaging detects not only tumor cells, but also nontumorous pulmonary tissues affected by bloodstream disturbance. Because a number of false-positive specimens were detected, further optimization of the dose of ICG and the timing of its administration may be required for thorough metastasectomy. Several false-negative specimens were also detected, suggesting the presence of ICG-negative metastatic tumors. Palpation during operation and imaging studies remain essential for detecting metastatic lesions, even in the era of ICG imaging.

10080 Background: Despite multimodal treatment concepts and complete surgical resection, prognosis in pediatric patients with pulmonary metastases from osteosarcoma has remained limited due to frequent relapse of disease. We investigated the results of an aggressive surgical approach. Methods: In a retrospective study, procedures and outcomes of pulmonary metastasectomy in the pediatric age group (up to 18 years) at our institution were analyzed over a period of 10 years (1999-2009). Resection of the primary osteogenic tumor and chemotherapy (CROSS-96-protocol and EURAMOS-1-protocol) were performed prior to thoracic surgery. Results: Forty-five pediatric patients (20 females) underwent pulmonary metastasectomies via sternotomy or sequential anterolateral thoracotomy at a mean age of 14 (6 -18) years. At primary surgery, a mean number of 7.9 (1 – 53) palpable suspicious lesions were resected per patient. Histo-pathological evaluation revealed 3.7 (0 – 40) metastases per patient. Mean total duration of surgery was 152 (46–323) minutes. Mean hospital stay was 10 days (3 – 33). In-hospital and 30-day mortality was 0%. The overall survival at 1 and 5 years was 97.8% and 77.3%, respectively. Mean disease-free-survival was 12.2 (3.2-38.0) months. In 19 (42.2 %) patients recurrent pulmonary metastases were detected and re-thoracotomies were required. Up to 7 procedures per patient were performed. Overall survival for patients undergoing more than one surgical procedure for recurrent lung metastases was not statistically different from survival in patients without relapse (p > 0.05). Survival was significantly better in patients initially presenting with less than 10 metastases (85.3 % vs. 54.1 % at 5 years, p = 0.028). Conclusions: Complete pulmonary metastasectomies are essential in pediatric osteosarcoma patients with lung metastasis. Repeated resections for recurrent relapses improve survival and may allow for long-term event-free-survival.
