A thorough understanding of the incidence, clinical presentation, treatment, prognosis, and psychosocial issues surrounding children with solid tumors enables the nurse to actively participate on the health care team. Although significant advances over the past two-and-a-half decades to improve the outcomes of children with cancer have occurred, there remains room for continued improvement, especially among children with advanced-stage nephroblastoma, neuroblastoma, HCC, and teratoma.

Fibrolamellar hepatocellular carcinoma (FHCC) is a unique histologic variant of HCC that occurs in a younger subset of patients than classical HCC, and is associated with a better prognosis. Wilms tumor (WT) is a malignant embryonal neoplasm of the kidney and is one of the most common solid tumors of childhood, occurring at an estimated frequency of 1 in 8000 to 10,000 births. Although second malignant neoplasms (SMNs) following therapy for WTs have been reported in the liver, the coexistence of HCC and WT is extremely rare. We present the first report of a synchronous anaplastic WT and FHCC in a previously healthy 4-year-old girl. Despite the presence of focal immunohistochemical positivity for p53 in the WT, molecular analysis failed to reveal a germline or somatic p53 mutation, and was inconclusive in establishing a clonal relation between the two tumors.

To determine the possible role of the epigenetic mechanisms in carcinogenesis of the hepatocellular carcinoma, we methylation-profiled the promoter CpG islands of twenty four genes both in HCC tumors and the neighboring non-cancerous tissues of twenty eight patients using the methylation-specific PCR (MSP) method in conjunction with the DNA sequencing. In comparison with the normal liver tissues from the healthy donors, it was found that while remained unmethylated the ABL, CAV, EPO, GATA3, LKB1, NEP, NFL, NIS and p27KIP1 genes, varying extents of the HCC specific hypermethylation were found associated with the ABO, AR, CSPG2, cyclin a1, DBCCR1, GALR2, IRF7, MGMT, MT1A, MYOD1, OCT6, p57KIP2, p73, WT1 genes, and demethylation with the MAGEA1 gene, respectively. Judged by whether the hypermethylated occurred in HCC more frequently than in their neighboring normal tissues, the hypermethylation status of the AR, DBCCR1, IRF7, OCT6, and p73 genes was considered as the event specific to the late stage, while that the rest that lacked such a distinguished contrast, as the event specific to the early stage of HCC carcinogenesis. Among all the clinical pathological parameters tested for the association with, the hypermethylation of the cyclin a1 gene was more prevalent in the non-cirrhosis group (P=0.021) while the hypermethylated p16INK4a gene was more common in the cirrhosis group (P=0.017). The concordant methylation behaviors of nineteen genes, including the four previously studied and their association with cirrhosis has been evaluated by the best subgroup selection method. The data presented in this report would enable us to shape our understanding of the mechanisms for the HCC specific loss of the epigenetic stability of the genome, as well as the strategy of developing the novel robust methylation based diagnostic and prognostic tools.
