Adult Hepatoblastoma: Systemic Review of the English Literature

Abstract

Aims: To review all the case reports or case series of patients with adult hepatoblastoma. Methods: A search of all case reports on adult hepatoblastoma in the English literature was performed using the PubMed database. Demographic information, clinical findings, treatment modalities and outcomes were extracted and analyzed. Results: A total of 36 English articles and 40 patients with adult hepatoblastoma were collected. All these cases were confirmed by pathological diagnosis. The median age of the 40 patients was 41.5 years, including 21 males and 19 females. Hepatitis B virus tests were positive in 6 patients, and 15 patients were positive for α-fetoprotein (AFP). Liver cirrhosis was only confirmed in 7 cases. Hepatoblastoma commonly forms a single giant mass within the liver. Twenty-three cases underwent radical liver resection, including 9 cases of comprehensive treatment. The median survival time for 27 patients with available follow-ups was 4 months; 1-year survival was 29.6%. In Cox multivariate analysis, curative liver resection was an independent prognostic factor for prolonged survival (p = 0.003). Conclusions: Curative liver resection can prolong survival. Improvements in outcome will require the development of more effective systemic therapies.

Hepatocellular Carcinoma in Tyrosinemia Type 1 Without Clear Increase of AFP

“…Theoretically, the malignancy could also have been a hepatoblastoma, which may present without increased AFP levels 10 and has been reported at least once in HTI. 11 The pathology of the explanted liver, however, clearly showed HCC.…”

GATA4 promotes hepatoblastoma cell proliferation by altering expression of miR125b and DKK3

“…Hepatoblastoma (HB) is the most common pediatric liver tumor in children under 5 years old [4] and accounts for approximately 1-4% of all malignant tumors in children [1, 2]. 0.5-1.5 children per million are diagnosed with HB each year [3], and incidences have increased in recent years.…”

Adult hepatoblastoma. A case report

“…Las imágenes radiológicas demuestran una única masa (entre 5-24 cm de diáme-tro) 9,10 , a veces encapsulada, que separa y comprime el parénquima normal hepático de las estructuras vasculares. Un 90% de las veces la alfa fetoproteína sérica se encuentra elevada, y es un buen marcador de respuesta al tratamiento 11 .…”
