Hepatoblastoma is the most common primary pediatric liver malignancy. The goal of treatment in hepatoblastoma is complete surgical resection. Recently published multinational collaborative studies are better defining risk factors for disease recurrence and guide optimal treatment strategy.
Successful margin-negative resection of hepatoblastoma is dependent on the location and extent of disease as defined by the PRETEXT classification. Liver transplantation is an appropriate treatment modality when complete oncological resection requires total hepatectomy. In general, advanced PRETEXT class as well as histologic features, age at presentation, tumoral production of α-feto protein and the presence of metastatic disease adversely affect outcome. Hepatoblastoma is chemosensitive and significant downstaging can occur with the use of neoadjuvant chemotherapy allowing for less extensive hepatectomy. In addition, patients at moderate-to-high risk of postresection recurrence should receive neoadjuvant chemotherapy. Cisplatin-based chemotherapy can allow for resection of transplantation of patients with metastatic disease when complete metasatectomy can be achieved albeit with inferior results.
Treatment of hepatoblastoma with surgical resection or liver transplantation is associated with excellent long-term results in the setting of modern chemotherapy.
肝母细胞瘤是最常见的小儿原发性肝脏恶性肿瘤。肝母细胞瘤的治疗目标是完全手术切除。最近发表的多国合作研究更好地定义了疾病复发的风险因素,并指导了最佳治疗策略。
肝母细胞瘤边缘阴性切除术的成功取决于 PRETEXT 分类定义的疾病位置和范围。当完全肿瘤切除需要全肝切除时,肝移植是一种合适的治疗方式。一般来说,高级 PRETEXT 分级以及组织学特征、发病年龄、肿瘤产生的甲胎蛋白和转移性疾病的存在都会对预后产生不利影响。肝母细胞瘤对化疗敏感,新辅助化疗可显著降期,从而允许进行范围较小的肝切除术。此外,有中度至高度术后复发风险的患者应接受新辅助化疗。顺铂为基础的化疗可使转移患者接受切除术或肝移植,当能够实现完全转移切除时(尽管结果较差)。
在现代化疗的背景下,手术切除或肝移植治疗肝母细胞瘤可获得极好的长期结果。
