Previous studies have shown conflicting results on the impact of tumor size on the prognosis of distant metastatic hepatocellular carcinoma. While patients with larger tumors had a higher mortality rate, propensity score matching analysis revealed no significant association between tumor size and prognosis in distant metastatic HCC.
Background Previous studies have shown that tumor size has an impact on the prognosis of hepatocellular carcinoma (HCC). Whether tumor size is related to the prognosis of distant metastatic HCC is unclear. The purpose of this study was to investigate the effect of tumor size on the prognosis of distant metastatic HCC. Methods Data on patients with HCC were collected from the (SEER) database of surveillance, epidemiology and final results. Propensity score matching (PSM) was used to reduce confounding factors and comprehensively evaluate the clinicopathological features and prognosis of distant metastatic HCC. Results There were 189 patients with distant metastatic HCC whose tumor size was <= 50 mm and 615 patients with a tumor size > 50 mm. The tumor sizes of distant metastatic HCC patients were associated with race, grade, surgical treatment, N and AFP. The Kaplan-Meier analysis showed that the mortality rate of patients with a tumor size > 50 mm was higher than that of patients with a tumor size <= 50 mm (p = 0.00062). However, there were no significant differences in mortality rates after adjusting for confounding variables by using propensity score matching (p = 0.23). Conclusion This propensity score matching study provides the best data in support of the following assertions: tumor size is not an independent prognostic factor for distant metastatic HCC.
