What the experts said30 expert statements
MRI using a hepatobiliary contrast agent is the first-line imaging study for patients with a liver tumor, allowing better visualization of multifocal disease and ideal assessment of hepatic vasculature
GuidelineAlex Tobin
Rib fractures or vertebral fractures are fairly common as a presentation factor with hepatic tumors in young children, particularly hepatoblastoma
ClinicalKatherine Somers
Fractures will heal as children go through their therapy, and kids are remarkable in their resilience and tend to be rather unbothered by their fractures once cancer therapy is underway
ClinicalKatherine Somers
Precocious puberty in a Tanner stage one patient is a sign that should prompt consideration of underlying malignancy on the differential
ClinicalKatherine Somers
High-risk therapy for hepatoblastoma includes cisplatin and doxorubicin, with dexrazoxane cardiac protectant given institutionally with doxorubicin
ClinicalKatherine Somers
Almost every young toddler with a large liver tumor requires aggressive nutritional support to get through intensive therapy and surgical procedures
ClinicalKatherine Somers
Weight loss or sarcopenia during active cancer therapy is associated with poor outcomes across all pediatric cancer diagnoses
EpidemiologicalKatherine Somers
Tumor board presentation and multidisciplinary conference approach is associated with improved success and long-term outcomes for pediatric liver tumor patients
EpidemiologicalAlex Bondoc
Maximum tumor shrinkage typically occurs after the first block or cycle of chemotherapy; subsequent blocks produce less shrinkage
ClinicalAlex Bondoc
ICG fluorescence is highly sensitive but not specific for tumor detection; it can help find multifocal disease and assess margins
ClinicalAlex Bondoc
In approximately 15% of lung resections, ICG fluorescence identifies lesions not visible on high-resolution axial imaging
ClinicalAlex Bondoc
The FIT trial (AHEP 1531) mandated liver biopsy for diagnosis before starting treatment
GuidelineRanga (Ranganathan)
Post-chemotherapy tumor response is maximum in initial stages; once tumor is replaced by blood pools and fibrous tissue, size doesn't decrease much further
ClinicalRanga (Ranganathan)
PRETEXT criteria define metastatic disease as more than 2 nodules greater than 3 millimeters in diameter or 1 nodule greater than 5 millimeters in diameter
GuidelineAlex Tobin
Even when first-side chest metastases show no viable tumor, the other side is still cleared surgically because combined chemotherapy and surgical clearance is the best pathway to cure
GuidelineKatherine Somers
Patients with hepatoblastoma are frequently born prematurely
EpidemiologicalAlex Tobin
End-stage renal disease early in life shows increased incidence of hepatoblastoma, not just autosomal recessive polycystic kidney disease
EpidemiologicalKatherine Somers
Cisplatin's primary toxicity is renal, and platinum excretion is fully dependent on a functioning renal system
ClinicalKatherine Somers
Patients on peritoneal dialysis can receive platinum chemotherapy using advanced pharmacokinetic and pharmacodynamic modeling without typical mandated hyperhydration
ClinicalKatherine Somers
For known predisposition patients, screening protocol starts with ultrasound and alpha-fetoprotein levels, accounting for different normal AFP ranges in first months of life
GuidelineKatherine Somers
PRETEXT IV multifocal disease requires liver transplantation; patients should be referred early to transplant program
GuidelineAlex Bondoc
In the United States, children with hepatoblastoma automatically receive Status 1B categorization on deceased donor list, the second highest stratum for organ allocation
GuidelineAlex Bondoc
Conventional hepatoblastoma is genomically quiet with very low mutation burden and invariably has point mutation or small deletion in exon 3 of CTNNB1 gene
ClinicalRanga (Ranganathan)
Hepatocellular neoplasm NOS shows more genomic instability with chromosomal gains and losses, characterized by CTNNB1 deletion, often large deletions or complete exon 3 skipping
ClinicalRanga (Ranganathan)
Beta-catenin immunohistochemistry is frequently weak positive or negative in HCC-NOS, serving as a diagnostic clue along with pleomorphic appearance and macrotrabecular arrangement
ClinicalRanga (Ranganathan)
HCC-NOS can be targeted with high-risk hepatoblastoma therapy to shrink tumors and make them amenable to surgery in most cases
ClinicalRanga (Ranganathan)
Every child with new cancer diagnosis meets with genetic counseling oncology team for complete genetic testing including germline testing if something is identified
GuidelineKatherine Somers
Radiomics can predict pure fetal histology hepatoblastoma with area under ROC curve of approximately 0.85
ClinicalAlex Tobin
Pure fetal histology hepatoblastoma patients are cured with resection alone and don't need chemotherapy
ClinicalAlex Tobin
Artificial intelligence can segment liver tumors very accurately at the level of an expert
