Hepatoblastoma (HB) frequently presents at an advanced and unresectable stage. Transcatheter arterial chemoembolization (TACE) had been attempted to improve the feasibility of removing the bulky tumor in the authors' hospital and the results were presented here to evaluate the effectiveness and therapeutic role of TACE in the HB infants. Eight patients (6 boys, 2 girls), ranging in age from 2 months to 12 months, had unresectable HB based on clinical manifestation, B-ultrasound (B-US), chest X-ray film, computed tomography (CT), blood chemistry, and serum alpha-fetoprotein (AFP), and were subjected to TACE 1-3 times. On each TACE, Adriamycin (ADR, 20 mg/m2), vincristine (VCR, 1.5 mg/m2), and cisplatin (CDDP, 40 mg/m2) dispersed in 5-10 mL lipiodol were infused into the tumor, and stainless-steel embolization coils were released into the main feeding artery until completely embolized. Then, all the patients were reexamined once a month. Digital subtractive angiography was performed and the therapeutic strategy of further TACE or surgery was individualized in terms of the changes of tumor stain and the newly forming feeding artery. Six children (75%) had a marked response after the first TACE and were judged as being surgically resectable, but one boy died of pneumonia just before the scheduled operation and another boy preferred further TACE. The other 2 patients had only a partial response and required further TACE before the operation. Thus 6 children eventually underwent complete surgical resection and 1 boy achieved successful disappearance of tumor after 3 episodes of TACE alone. Seven children had an excellent recovery and remained tumor-free for 15-49 months. The results indicate that TACE is an effective and useful preoperative therapeutic choice for unresectable hepatoblastoma, and can improve the resectablity of the bulky tumor and the survival rate of HB patients. Multiple TACE could enhance the therapeutic effect and should be considered if indicated. 相似文献

Hepatic arterial chemoembolization using Lipiodol Ultra-fluid (Laboratoire Guerbet), doxorubicin HCl, and Gelfoam (Upjohn)(L-TAE) produced good results in an infant with a hepatoblastoma initially considered to be difficult to resect. Lipiodol selectively accumulated in the tumor, and a marked reduction in tumor size with decrease of alpha-fetoprotein was observed. One month after L-TAE, left hepatectomy was performed uneventfully with a good postoperative course. L-TAE appears to be a useful treatment for hepatoblastoma.

Until now surgical resection was still considered as the only choice of successful treatment of hepatoblastoma. Therefore, successful use of transcatheter arterial chemoembolization (TACE) alone to cure the unresectable hepatoblastoma in an infant was firstly reported. A 6-month-old boy presented with a huge abdominal mass and was found to have a hepatoblastoma of 17.5 cm x 11.5 cm x 10 cm on computed tomography (CT) scan. The serum alpha-fetoprotein (AFP) was elevated to 6250 ng/mL. On the first TACE the main feeding arteries were completely occluded by stainless steel embolization coils. After one month tumor shrinkage was 75%, but a newly formed feeding artery was found and embolized on second TACE. Since the third TACE no newly formed feeding artery was found and 6 courses of intravenous chemotherapy were consolidated. On the last DSA and CT the tumor was completely disappeared and AFP returned to normal. During the follow-up he remained disease-free for 33 months until the present report. TACE may provide an additional promising choice in the treatment of hepatoblastoma. 相似文献

We report the case of a girl with multi-focal hepatoblastoma in whom chemotherapy alone has resulted in long term event-free survival and possibly cure, without any surgical procedure apart from biopsy for initial diagnosis. At presentation she had a large tumour arising from the left lobe of liver and two other separate masses were noted in the right lobe, but the lungs were free of metastases. Histology showed a foetal type of hepatoblastoma. The serum alpha-feto protein (AFP) level was 44,000 iu/litre. Chemotherapy was started using the triple drug regime recommended for “high risk” (of relapse) patients in the SIOPEL 2 hepatoblastoma protocol of the International Society of Paedaitric Oncology (SIOP). Within a few weeks her abdominal girth decreased, the child became much more comfortable. Drug-induced cardiotoxicity, ototoxicity and nephrotoxicity were not observed. After a total of 4 courses of chemotherapy (completed at the end of August 1998) a CT scan showed that all 3 tumours were smaller but that there were residual multifocal defects in the liver neither hepatic resection nor liver transplantation were considered safe or appropriate. 6.5 years after completion of chemotherapy and now aged 8.5 years the child is in normal health and at school with normal liver size, serum AFP levels and chest imaging. 相似文献

Nine of 11 patients with hepatoblastoma treated with cisplatin (DDP) based chemotherapy had a complete (CR) or partial (PR) remission. Five of these patients had measurable pulmonary disease and four achieved a CR of pulmonary lesions. The average interval of disease control following DDP was three times that of Adriamycin (ADR). DDP is an effective agent in the treatment of hepatoblastoma. 相似文献

Though surgical resection is the main stay of treatment for childhood hepatoblastoma (HB), many are unsuitable for radical
surgery at diagnosis due to extensive intrahepatic and/or extra hepatic disease. We report experience in five patients of
HB from a single institution (2001–2005) with preoperative Neoadjuvant chemotherapy (NACT) followed by surgery. Three patients
received cisplatin, doxorubicin; and two cisplatin/vincristine/5-fluorouracil. All showed more than 50% reduction in tumor
size confirmed by CT scan. Hepatic resection R0 was performed in all. There was no chemotherapy related toxicity nor post
surgical morbidity or mortality. All are disease free at median follow up of 4 years. NACT produces adequate down staging
of the HB with acceptable toxicity. Though cisplatin with doxorubicin produced good results, new protocol with cisplatin,
vincristine and 5FU is promising without cardiotoxicity. 相似文献

肝母细胞瘤(hepatoblastoma,HB)是胚胎性肿瘤的一种,恶性程度较高,好发于3岁以下儿童。手术切除为HB首选治疗方案,手术切除的完整性关系到肿瘤预后。HB对化疗敏感,可辅助化疗、放疗等治疗手段。目前主流化疗方案为C5V(cisplatin+5-Fluorouracil+vincristine,顺铂+5-氟尿嘧啶+长春新碱)方案。对难治性HB可实施肝移植,且自体肝移植术在临床上已有成功案例。此外,靶向治疗(如针对NK1R及PI3K/Akt等通路的靶向药物治疗)已进入临床试验,而免疫治疗尚处于研发阶段。 相似文献

BACKGROUND: Despite the advent of effective chemotherapy,a poor prognosis has been reported for patients with metastatic hepatoblastoma. To improve this prognosis, we conducted high-dose chemotherapy with autologous bone marrow rescue in patients with metastatic hepatoblastoma. METHODS AND RESULTS: Three patients were treated with high-dose chemotherapy. In patient 1, high-dose chemotherapy was given after the patient's first pulmonary relapse.Additional pulmonary metastases, which developed more than 6 months after high-dose chemotherapy, were treated by multiple thoracotomy without additional chemotherapy. Patient 2 presented additional pulmonary metastases soon after the end of the first thoracotomy and high-dose chemotherapy. Because of a decreased serum alpha-fetoprotein level after re-excision of the pulmonary metastases, a second round of high-dose chemotherapy was performed. In patient 3, multiple pulmonary metasteses responded to preoperative chemotherapy and disappeared according to the chest computed tomography. Intensive treatment with a high-dose chemotherapeutic regimen was performed at the end of postoperative chemotherapy. All three patients are alive and well, more than 6 years after receiving their diagnosis. CONCLUSION: The role of high-dose chemotherapy in treatment of metastatic hepatoblastoma could not be clarified,because of the small number of patients. However, the better outcome of our patients indicates that multimodal therapy, including high-dose chemotherapy, may improve the outcome of the patients with metastatic hepatoblastoma. 相似文献

The objective of this work was to test feasibility and efficacy of hepatic artery chemoembolization (HACE) in unresectable malignant liver tumors. Five patients aged from 1-12 years were treated in the Medical University of Gdansk from 1999 to 2002. All had locally advanced tumors, which did not respond to systemic chemotherapy: four, hepatoblastoma (HB) and one, hepatocellular carcinoma (HCC). Arteriography was performed and chemoembolization suspension (cisplatin + doxorubicin + mitomycin mixed with lipiodol) was injected, followed by gelatin foam particles. The procedure was performed one to three times in each patient. In four patients (three, HB, one, fibrolamellar HCC), tumor response was observed, with decrease in the diameter of the mass of 25-33% and fall in the AFP level of 83-99%. One child with HB was non-evaluable due to early death caused by systemic myelotoxicity. Two patients (2 HB) underwent macroscopically complete tumor resection, 1 is alive and well, and 1 died at the end of surgery for an unknown reason (possibly related to cardiotoxicity of earlier systemic chemotherapy). One HB patient was successfully transplanted after two HACE courses. The only HCC patient died because of pulmonary oil embolism immediately after the third HACE course. HACE can lead to tumor regression in most cases and may be considered an alternative for patients with unresectable liver tumors who do not respond to primary systemic chemotherapy and are not candidates for liver transplantation for various reasons. 相似文献

Surgical resection remains the cornerstone of cure in hepatoblastoma (HB). Meticulous review of contrast enhanced CT/MR imaging facilitates PRETEXT and POST‐TEXT grouping to determine optimal timing and desired extent of liver resection. Excellent knowledge of liver anatomy is essential and the dissection must ensure protection of the vascular inflow and outflow to the remaining liver at all times. Referral to a liver specialty center in advanced cases may facilitate resectability. Potential surgical complications include bleeding, vascular injury, cardiac arrest, liver failure, and bile leak. The risk of complications can be minimized with preoperative planning, appropriate referral, and precise surgical technique.

Surgical treatment of hepatoblastoma in children 总被引:2,自引:0,他引:2
Hepatoblastoma is the most common liver malignancy in children. With rare exceptions, complete tumour resection is required
to cure the patient. Radical tumour resection can be obtained either with standard partial hepatectomy or orthotopic liver
transplantation. At present, the surgical approach to hepatoblastoma differs significantly between treatment groups in different
parts of the world. Our aim was to review current surgical policy in hepatoblastoma. All aspects of surgery in hepatoblastoma
are discussed, including biopsy, tumour resection principles, modern achievements in the field of liver surgery, and the indications
and potential contraindications for liver transplantation. Every effort should be made to resect hepatoblastoma completely
either by standard partial hepatectomy or by the use of liver transplantation in difficult or clearly unresectable cases. 相似文献
