Summary
Female patients with hepatocellular carcinoma (HCC) experience longer survival than males, even with similar tumor characteristics and liver function. This suggests a distinct natural history of HCC between genders.
Area of Science:
- Hepatobiliary Medicine
- Oncology
- Cancer Research
Background:
- Hepatocellular carcinoma (HCC) is a prevalent cancer globally, disproportionately affecting males.
- Existing research indicates significant male predominance in HCC incidence, but reasons remain unclear.
- Limited data exists on sex-based differences in HCC progression and survival.
Purpose of the Study:
- To investigate sex-based differences in hepatocellular carcinoma (HCC) progression and survival.
- To compare clinicopathologic characteristics and their impact on survival between male and female HCC patients.
- To determine if female gender confers a survival advantage in unresectable HCC.
Main Methods:
- A retrospective analysis of 1138 hepatocellular carcinoma (HCC) cases over 17 years.
- Overall survival (in months) was the primary endpoint, measured from diagnosis to death.
- Log rank test was used to compare survival rates between subgroups.
Main Results:
- Significant differences observed in disease progression at diagnosis and survival times between genders.
- Females demonstrated longer survival than males when matched for liver function and tumor extent.
- Findings suggest a different natural history of HCC in women compared to men.
Conclusions:
- Female gender is associated with a survival advantage in unresectable hepatocellular carcinoma (HCC).
- This advantage persists even when tumor characteristics, liver function, and coexisting liver disease are similar.
- The study highlights important sex-based differences in HCC outcomes.
