摘要
To compare the overall survival (OS), disease-free survival (DFS) and liver-cancer-specific survival (LCSS) of elderly (≥65 years) and younger patients (< 65 years) with early-stage hepatocellular carcinoma (HCC) using ultrasound-guided percutaneous microwave ablation (US-PMMA).From January 2002 to December 2017, 510 elderly and 1053 younger patients were diagnosed with early-stage HCC according to the Milan criteria. All of these patients were treatment-naïve to US-PMMA. Baseline characteristics were collected to identify any risk factors to determine the survival outcomes. OS, DFS, and LCSS probabilities were calculated with the Kaplan-Meier method and compared using the Log-rank test.Complete ablation was achieved in all patients. Elderly patients were more likely to be, hepatitis C virus infection, comorbidities, cirrhosis, larger tumors, poor liver functional reservation, more ablation points, longer ablation time, longer hospital stays, and higher hospitalization costs (P < 0.05). Over the follow-up period (12-156 months), no significant differences were detected in OS, DFS, and LCSS between the two groups ( P = 0.092, 0.318, and 0.183). r-GT, ALB and ablation session were significant factors for OS, r-GT and ALB for LCSS, and cirrhosis, tumor number, AFP and ablation points for RFS in the multivariate analysis, respectively. No treatment-related deaths occurred in the two groups. Any complications were treated as appropriate.Although advanced age and comorbidities are intrinsic factors in elderly HCC patients, similar survival outcomes were obtained in elderly and younger HCC patients treated by US-PMWA, despite elderly patients having more comorbidities.
