Neoadjuvant chemotherapy before surgery of hepatoblastoma

Outcomes of hepatoblastoma in the Indian context

A comprehensive review and critical appraisal of published and grey literature was undertaken to identify current treatment practices and outcomes of children with hepatoblastoma in India. Eight single-centre studies with 157 patients (range five to 36 patients in each study) were included. Pre-operative chemotherapy (mainly cisplatin and doxorubicin) followed by surgical resection and additional chemotherapy was the usual practice. There was no stratification of treatment by risk group in any of the studies. The median event-free survival ranged from 33-100%. The two main reasons for treatment failure were treatment-related mortality (0-50%) and progression of disease (0-30%).

Hepatoblastoma: Analysis of treatment outcome from a tertiary care center

Aim:

This study was designed to retrospectively review our experience with the multimodality management of hepatoblastomas (HB).

Materials and Methods:

Thirteen patients were treated for HB between 2000 and 2007. The clinical presentations, chemotherapy tolerance and response, surgical procedure undertaken, and complications were analysed.

Results:

Median age of the population was 12 months (3-60 months), with a male-to-female ratio of 3.3:1. Nine patients were treated with neoadjuvant chemotherapy incorporating cisplatin and adriamycin. Primary surgery was done in four patients. Extent of hepatic resection in the operated patients varied. Mixed type was the predominant histopathological diagnosis. Adjuvant chemotherapy was well tolerated with no morbidity or mortality. Five-year event-free survival (EFS) and overall survival (OS) of all the 13 patients is 76.9%. All the nine patients who could complete multimodality treatment are alive with no evidence of disease or complications with median follow-up of 63 months (46-122 months).

Conclusions:

Treatment of HB with multidisciplinary approach was well tolerated. OS and EFS of patients were comparable with published studies.

Patterns of hepatoblastoma and hepatocellular carcinoma in children after universal hepatitis B vaccination in taiwan: a report from a single institution in southern Taiwan

BACKGROUND

To retrospectively evaluate clinical features, treatment, and outcome of patients with hepatoblastoma (HB) and hepatocellular carcinoma (HCC).

METHODS

From January 1994 to December 2007, 16 patients of HB and 13 cases of HCC were reviewed.

RESULTS

The mean age of HB patients was much younger than HCC patients (1.2 vs. 11.5 y). There was an 84.6% positive rate for hepatitis B surface antigen in HCC, but none for HB. Mean serum alpha-fetoprotein level was higher with HCC (654,158 ng/mL) than the HB patients (352,843 ng/mL), especially higher in HCC with lung metastasis. Among the HB patients, 12 (75%) had thrombocytosis and 6 (37.5%) had microcytic anemia with high or normal ferritin, whereas only 3 of 13 with HCC (23.1%) had thrombocytosis and none had microcytic anemia. All HBs were resectable either before or after chemotherapy, but only 4 (30.8%) HCCs were resectable. Five-year disease-free survival rate was significantly higher in HB (87%) than in HCC (30%, P<0.001).

CONCLUSIONS

Hepatitis B infection was still the most important factor associated with HCC in children even after the national vaccination program against hepatitis B. Extreme thrombocytosis, anemia, alpha-fetoprotein levels are important factors associated with difference in long-term outcomes in children with HB and HCC.

Hepatoblastoma: a single institutional experience of 18 cases

Hepatoblastomas are the most common liver tumours in children. However, they are rare as compared to other solid malignancies. Thus, there is a need to integrate data from surgical centers around the world to provide a clearer view on the outcomes of multidisciplinary management of these tumours. We set out to retrospectively review our experience of patients with surgically resected hepatoblastomas looking at primary and secondary outcomes. Children diagnosed with hepatoblastoma and managed surgically (along with chemotherapy) at a single institution between 1 January 2000 and 31 May 2007, were analyzed. Out of the 18 patients, there were 12 male and 6 female patients. The median age was 18 months (range 8-72). A palpable mass in abdomen was the presenting symptom in 88% patients. Sixteen patients (88.8%) underwent major liver resection. Sixteen patients (88.8%) received preoperative chemotherapy. Complete gross resection (stage I and II) was achieved in all 18 patients (100%). The mortality and morbidity rates were 0 and 11.2%, respectively. The 80-month disease-free survival was 67%. This series, the largest from India in terms of surgical resections for hepatoblastoma, reaffirms that major liver resection can be performed with minimal perioperative mortality and morbidity and that the use of chemotherapy has definitely helped in down staging tumours for liver resection.
