title: Clinicopathological features and prognostic factors of young patients with surgically treated liver cancer.
abstract: This article compares the clinical characteristics and prognosis of young patients in different age groups with liver cancer (LC). In this retrospective study, we searched the Surveillance, Epidemiology, and End Results population-based database and identified 2641 patients who had been diagnosed with LC between 1988 and 2005. These patients were categorized into 2 different age ranges: Group 1 (≤35 years) and Group 2 (36-45 years). Five-year cancer-specific survival (CSS) data were obtained. Kaplan-Meier methods and multivariable Cox regression models were used to analyze the long-term survival outcomes and risk factors. There were significant differences between the age groups for stage and tumor size (P < 0.001). The 5-year liver CSS rate was 20.4% and 14.5%, respectively (P < 0.001). Univariate and multivariate analysis also confirmed the difference (P < 0.001). Further analysis showed that this significant difference existed in localized, regional, and distant-stage patients. Young patients with LC of age 18 to 45 years are inherently heterogeneous. Patients aged ≤35 years have better CSS than those aged 36 to 45 years, despite exhibiting unfavorable clinicopathological characteristics.
