Juvenile Hepatocellular Carcinoma in a Healthy Liver

Overall Survival of Young Patients with Hepatocellular Carcinoma in Barcelona Clinic Liver Cancer Stage B in a Retrospective Study Based on a Multicenter Cohort

BACKGROUND

Hepatocellular carcinoma (HCC) is usually diagnosed in patients at the age of > 45 years. We aimed to determine the prognosis of patients with HCC at the age of 30-44 years compared with that of patients at a more senior age.

METHODS

Based on the Sun Yat-sen University Cancer Center database, a total of 1745 patients with HCC were retrospectively enrolled and were assigned to three age groups (30-44, 45-59, and 60-70 years). The primary endpoint was overall survival. Among baseline characteristics, five variables including sex, serum albumin level, total bilirubin level, the maximum tumor diameter, and the number of tumor nodules were adjusted using propensity score matching.

RESULTS

Patients aged 30-44 years presented a worse overall survival, a greater number of HCC nodules, a greater maximum tumor diameter, and higher serum alpha-fetoprotein (AFP) concentration than those aged 45-59 years in a crude analysis (p < 0.05). Using propensity score matching, the difference in overall survival between the two cohorts was canceled (p > 0.05).

CONCLUSION

The prognosis of patients with HCC at age 30-44 years was equal to that of patients aged 45-59 years.

Effectiveness of Chemotherapy on Long-Term Survival in a Case of Advanced Juvenile Hepatocellular Carcinoma Without Viral Hepatitis Infection

Hepatocellular carcinoma (HCC) usually occurs in settings of cirrhosis and chronic hepatitis B or C virus (HBV and HCV, respectively) infection; it is extremely rare in patients <40 years of age since viral- or alcohol-induced chronic hepatitis develops over a prolonged period. Juvenile HCC is mostly associated with persistent HBV infection; cases unrelated to HBV or HCV infection (non-B, non-C juvenile HCC) are sporadic and treated in the same way as classical HCC. A woman in her late 30s was diagnosed with HCC in a healthy liver; her imaging findings were typical of HCC with bone metastasis. She was administered a combination of tyrosine kinase inhibitors, immune checkpoint inhibitors, and vascular endothelial growth factor inhibitors. Throughout chemotherapy, the liver reserve was Grade A on the Child-Pugh classification and tumor markers remained under control without marked elevation. Our patient is the first reported long-term survivor of unresectable non-B, non-C juvenile HCC following chemotherapeutic treatment.

Hepatocellular Carcinoma in Non-Fibrotic Liver: A Narrative Review

Hepatocellular carcinoma (HCC) in a non-fibrotic liver (F0) is considered to be rare, and there is a marked paucity of studies in the literature on this HCC type. A review of the literature shows some important clinical and tumor characteristics: (a) it occurs mainly in young female and elder male patients; (b) clinically, under normal hepatic function, alpha-fetoprotein level is often normal, and there are no risk factors; (c) associated with metabolic disease; (d) macroscopically, single large lesions are noted; and (e) microscopically, the lesions are well-differentiated and encapsulated. Radiological imaging results are straightforward, showing arterial hyperenhancement and later wash-out. The combined use of B-mode and contrast-enhanced (CE) ultrasound (US) is the most reliable and cost-effective diagnostic method. Few peri-and post-operative complications are noted and 5-year survival is not inferior to patients with HCC on fibrosis liver despite the lesion's large size. Most clinicians believe that HCC is unlikely to occur if patients have no symptoms and normal hepatic function. Although detailed clinical data are very limited, we expect that this review will help to improve the clinical management of HCC in non-fibrotic livers.
