Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="pbc25077-sec-0001" sec-type="section"> <title>Background</title> <p>The aim of this study was to assess the prognostic value of multifocality and the effectiveness of two different therapeutic strategies in patients with newly diagnosed hepatoblastoma.</p> </sec> <sec id="pbc25077-sec-0002" sec-type="section"> <title>Procedures</title> <p>Between 1998 and 2011, 31 patients diagnosed with hepatoblastoma were referred to Ospedale Papa Giovanni XXIII, Bergamo, Italy. Patients were stratified according to SIOPEL protocols into high‐risk (HR if AFP <100 ng/mL and/or PRETEXT IV and/or vascular invasion and/or extra‐hepatic intra‐abdominal disease and/or metastases) and standard‐risk (SR, all others). The patient data we evaluated were: multifocality; patient age; gender; platelet count; AFP level at diagnosis, during treatment and follow‐up; histotype; gestational age; birth weight; surgery (either resection or transplantation) and chemotherapy regimen adopted before and after surgery. The outcome measures were event free survival (EFS) and overall survival (OS); survival curves were estimated according to Kaplan–Meier.</p> </sec> <sec id="pbc25077-sec-0003" sec-type="section"> <title>Results</title> <p>EFS and OS were associated significantly with multifocality (3‐year EFS 40% vs. 95%, <italic>P</italic> = 0.006; 3‐year OS 42% vs. 95%, <italic>P</italic> = 0.004). Multivariate analysis demonstrated that multifocality predicts lower EFS (hazard ratio 10.01, <italic>P</italic> = 0.007). Other factors at diagnosis did not reach statistical significance. A marked treatment dependent improvement was associated with intensive chemotherapy given both before and after liver transplantation (<italic>P</italic> = 0.06).</p> </sec> <sec id="pbc25077-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Patients diagnosed with multifocal tumors had lower EFS levels. Multifocality should be taken into account for future stratification and further studied to assess genetic profile, immunochemistry and prognostic role.
