摘要:
目的 探讨肝动脉化疗栓塞(the arterial chemoembolization,TACE)联合射频消融(radiofrequency ablation,RFA)治疗巴塞罗那分期(Barcelona clinic liver cancer,BCLC)中晚期原发性肝癌(hepatocellular carcinoma,HCC)患者预后的影响因素。 方法 回顾性分析2013年2月—2015年2月在温州医科大学附属舟山医院行TACE联合RFA治疗的76例BCLC中晚期HCC患者的临床资料。采用Kaplan-Meier法单因素分析和Cox多因素回归分析探究影响患者中位总体生存期(overall survival,OS)和中位无疾病进展生存期(progression-free survival,PFS)的相关因素。 结果 76例患者中位OS为27个月(11~68个月),中位PFS为15个月(4~63个月)。Kaplan-Meier法单因素分析结果显示,体能状态(PS)评分、肝功能Child-Pugh分级、肿瘤个数、肿瘤直径、门静脉癌栓、甲胎蛋白、替吉奥治疗以及RFA治疗次数与中位OS相关(均P<0.05);肝功能Child-Pugh分级、肿瘤个数、肿瘤直径、门静脉癌栓、替吉奥治疗以及RFA治疗次数与中位PFS相关(均P<0.05);Cox多因素分析结果显示,肿瘤直径增大、有门静脉癌栓为患者OS和PFS的独立危险因素(均P<0.05),多次RFA治疗、替吉奥治疗为PFS的独立保护因素(均P<0.05)。 结论 口服替吉奥、增加RFA治疗次数对控制TACE联合RFA治疗的BCLC中晚期HCC患者的肿瘤进展具有重要帮助,而肿瘤直径增加、门静脉癌栓是影响患者预后的独立危险因素,临床应采取相应措施进行防治。 Abstract:Objective To investigate the prognostic factors of the arterial chemoembolization (TACE) combined with radiofrequency ablation (RFA) in the treatment of patients with advanced hepatocellular carcinoma (HCC) at Barcelona Clinic stage (BCLC). Methods The clinical data of 76 patients with advanced HCC with BCLC who received TACE combined with RFA treatment in our hospital from February 2013 to February 2015 were retrospectively analysed. Kaplan-Meier univariate analysis and Cox multivariate regression were used to analyse the factors affecting overall survival (OS) and progression-free survival (PFS) of patients. Results The median OS was 27 months (11 - 68 months), and the median PFS was 15 months (4 - 63 months) in the 76 patients. Kaplan-Meier univariate analysis showed that physical status (PS) score, Child-Pugh grade of liver function, tumour number, tumour diameter, portal vein tumour thrombus, alpha foetal protein, Teggio treatment and times of RFA treatment were closely correlated with median OS (all P < 0.05). Liver function Child-Pugh grade, tumour number, tumour diameter, portal vein tumour thrombus, Teggio treatment and the frequency of RFA treatment were significantly correlated with median PFS (all P < 0.05). Cox multivariate analysis showed that enlargement of tumour diameter and portal vein tumour emboli were independent risk factors for OS and PFS (all P < 0.05), and multiple RFA treatment and Teggio treatment were independent protective factors for PFS (all P < 0.05). Conclusion Oral administration of Teggio and increasing the number of RFA treatments are of great help to control the tumour progression in BCLC patients with middle and advanced HCC treated with TACE combined with RFA. However, increase in tumour diameter and portal venous cancer thromboembolism are independent risk factors affecting the prognosis of patients, and corresponding measures should be adopted for clinical prevention and treatment. -
