Objective To investigate the correlative factors influencing long-term efficacy of patients with liver neoplasms after interventional therapy. Methods A total of 495 patients underwent transcatheter arterial chemoembolization (TACE), and the data were retrospectively analyzed. The patients were divided into two groups according to the survival time after interventional therapy: ≥5 years and ＜5 years. Correlative factors were compared in both two groups. Results In 31 patients survived longer than 5 years, 18 patients with Lipiodol filling type Ⅰ tumor, and 13 with type Ⅱ tumor. The 5, 7, 10 years survival rate in all 495 patients was 6.26% (31/495), 1.41% (7/495) and 0.40% (2/495), respectively. Factors including tumor pattern, clinical classification, the features of angiography, with or without heptic arteriovenous fistula, the pattern of Lipiodol filling, with or without invasion and metastasis, hepatic function, patient's age, tumor diameter, AFP value before and after TACE, the variety of AFP value after TACE influenced the long-term survival rate after interventional therapies (P＜0.05). Conclusion The characteristics of tumor, patient's status, the quality of TACE, whether combined with PEI, and/(or) anti-virus treatment have significant influence on long-term efficacy after interventional therapy in patients with liver neoplasms.
