Methods
A total of 2,200 patients with RB were admitted at the Department of
Pediatrics in Beijing Tongren Hospital, Beijing, China, between January
2009 and January 2019. This hospital is one of the largest and best
tertiary eye centers in China. Among the patients with RB, five patients
with hepatic metastases were eligible for this study, and their clinical
data were analyzed retrospectively. The study protocol was approved by
the Medical Ethics Committee of the Beijing Tongren Hospital, and
written informed consent was obtained from the patients or guardians (in
the case of minors) for the publication of this report and associated
images. Serum biochemistry, neuron-specific enolase (NSE), alpha
fetoprotein (AFP), bone marrow cytology, cerebrospinal fluid cytology,
superficial lymph node ultrasound, abdominal computed tomography (CT),
and contrast-enhanced magnetic resonance imaging (MRI) of the orbits
were performed on all patients. Positron emission tomography (PET)-CT
was recommended for all five patients; however, two patients declined
for financial reasons.
Multi-drug combination chemotherapy including vincristine, etoposide,
carboplatin/cisplatin, cyclophosphaminde/isfosfamide, and topotecan was
administered.8 Intrathecal injection of methotrexate,
cytosine arabinoside, and dexamethasone was administered when the CNS
was involved.10
Abdominal CT and contrast-enhanced MRI of the orbit were performed after
every two or three chemotherapy cycles. Radiotherapy after chemotherapy
and autologous peripheral blood stem cell transplantation (APBSCT) were
scheduled. Adverse reactions to radiotherapy and chemotherapy were
evaluated according to the Common Terminology Criteria for Adverse
Events guidelines.11
