超声引导射频消融治疗肝脏恶性肿瘤302例肿瘤残留危险因素分析

背景与目的：射频消融(radiofrequencey ablation,RFA)是治疗原发性肝癌和部分转移性肝癌的有效的方法,本研究探讨肝脏恶性肿瘤RFA治疗后肿瘤残留的危险因素。方法：回顾性分析2010年1月-2013年3月复旦大学附属肿瘤医院收治的302例原发性肝癌和转移性肝癌患者共691个肝内病灶接受RFA治疗的临床资料,采用单因素和多因素Logistic Regression模型分析与RFA治疗后肿瘤残留有关的危险因素。结果：RFA治疗后272例(90.07%)患者的632个(91.46%)病灶完全消融,肿瘤残留率为8.54%。直径≤3 cm的肿瘤残留率为6.30%,3~5 cm为9.57%,>5 cm为28.57%;靠近肝内大血管和胆囊肿瘤残留率分别为17.14%和18.52%;联合其他局部治疗和未联合其他局部治疗的肿瘤残留率分别为7.02%和13.41%。多因素分析显示,肿瘤最大直径>5 cm(P=0.044)、靠近肝内大血管(P=0.039)和未联合其他局部治疗(P=0.001)是RFA治疗后肿瘤残留的独立危险因素。112例患者282个病灶最大直径3~5 cm,RFA治疗后肿瘤残留多因素分析显示,肿瘤靠近肝内大血管(P=0.014)、单针射频(P=0.047)和未联合其他局部治疗(P=0.023)是RFA治疗后肿瘤残留的独立危险因素。结论：超声引导的RFA治疗可以获得满意的消融效果,其中肿瘤靠近肝内大血管、肿瘤最大直径>5 cm和未联合其他局部治疗是肿瘤残留的独立危险因素,对于直径为3~5 cm的肿瘤,除靠近肝内大血管和未联合其他局部治疗外,单针射频也是肿瘤残留的独立危险因素,采用双针或多针治疗可以提高消融效率,降低肿瘤残留。     

肝癌射频治疗后的DSA征象分析

背景与目的:肝射频消融术(RFA)是肝癌综合治疗中的一项重要手段,CT常用于评估其治疗效果和肿瘤复发,但CT很难发现＜1 cm的复发灶,因此必要时行血管造影术(DSA)能发现隐匿的复发灶,是CT有益的补充手段.为此,本文研究肝癌RFA后的DSA征象,以提供影像学参考.方法:2007年1月至2008年4月对17例经临床、影像学及肝穿刺活检确诊为肝癌或转移性肝癌患者行RFA后进行DSA造影.结果:DSA显示射频治疗的肿瘤区多为圆形或类圆形无染色的低密度区;边缘区可见以下几种征象:局部染色、肝动脉门静脉瘘、边缘区出血、边缘复发和无异常造影征象.肝内异位复发灶造影表现同其原发肿瘤常见造影表现.本组9例造影发现原位边缘复发和(或)肝内异位复发灶.结论:发现和鉴别射频治疗区域的边缘征象是判断局部复发的关键.DSA在榆出＜1 cm的边缘结节复发和肝内复发灶方面优于CT.     

肝癌术后肝动脉化疗栓塞治疗患者肿瘤复发的影响因素分析

目的 探讨影响肝癌术后经导管肝动脉化疗栓塞治疗(TACE)患者肿瘤复发的危险因素.方法 选择并收集200例肝癌患者的年龄、性别等一般人口学特征和临床特征资料并对患者进行随访追踪,采用Logistic逐步回归分析法分析肿瘤复发的影响因素.结果 在200例患者中130例有肿瘤复发,占65.0％.Logistic逐步回归分析结果显示,血管癌栓(OR=3.796;95％CI:1.871～7.702)、侵透肝被膜(OR=3.340;95％CI:1.067～10.451)、肝硬化(OR=2.790;95％CI:1.771～4.396)、包膜完整性(OR=2.048;95％CI:1.273～3.298)和最大癌结节直径(OR=1.739;95％CI:1.014～2.980)是肝癌术后TACE治疗患者肿瘤复发的危险因素.结论 肝癌术后TACE治疗患者的肿瘤复发率较高,术前有无血管癌栓、侵透肝被膜和肝硬化,包膜是否完整,以及肿瘤的直径等均会影响肿瘤复发,临床需要加强患者术后复诊和康复治疗.     

Recurrence-free survival after radiofrequency ablation of hepatocellular carcinoma. A registry report of the impact of risk factors on outcome

BACKGROUND: Despite the high complete necrosis rate of radiofrequency ablation (RFA), tumor recurrence, either local tumor recurrence or new tumor formation, remains a significant problem. Purpose of this study is to evaluate the pattern and risk factors for intrahepatic recurrence after percutaneous RFA for hepatocellular carcinoma (HCC). METHODS: We studied 40 patients with 48 HCCs (< or = 3.5 cm) who were treated with percutaneous RFA. The mean follow-up period was 24.1 +/- 15.7 months. We evaluated the cumulative disease-free survival of overall intrahepatic recurrence, local tumor progression (LTP) and intrahepatic distant recurrence (IDR). Thirty host, tumoral and therapeutic risk factors were reviewed for significant tie-in correlation with recurrence: age; gender; whether RFA was the initial treatment for HCC or not; severity of liver disease; cause of liver cirrhosis; contact of tumor to major hepatic vessels and liver capsule; degree of approximation of tumor to the liver hilum; ablation time; degree of benign pre-ablational enhancement; sufficient safety margin; tumor multinodularity; tumor histological differentiation; tumor segmental location; maximum tumor diameter; degree of tumor pre-ablational enhancement at arterial phase CT, MRI or CT-angiography; and laboratory markers pre- and post-ablation (AFP, PIVKA II, TP, AST, ALT, ALP and TB). RESULTS: The incidence of overall recurrence, LTP and IDR was 65, 23 and 52.5%, respectively. The cumulative disease-free survival rates were 54.6, 74.8 and 78.3% at 1 year, 27.3, 71.9 and 46.3% at 2 years and 20, 71.9 and 29.4 at 3 years, respectively. Univariate and multivariate analysis showed that the significant risk factors for LTP were: tumor size > or = 2.3 cm, insufficient safety margin, multinodular tumor, tumors located at segments 8 and 5, and patient's age > 65 years (P < 0.05). No significant risk factor relationship for IDR could be detected. CONCLUSION: Our results would have clinical implications for advance warning and appropriate management of patients scheduled for RFA. Patients at risk of LTP should be closely monitored in the first year. Furthermore, regular long-term surveillance is essential for early detection and eradication of IDR.     

Risk factors for local recurrence of small hepatocellular carcinoma tumors after a single session,single application of percutaneous radiofrequency ablation

BACKGROUND: The objectives of this study were to clarify risk factors for local tumor recurrence and to determine which patients with hepatocellular carcinoma (HCC) are most suitable for a single session, single application of percutaneous radiofrequency (RF) ablation. METHODS: Fifty-six consecutive patients with 65 HCC tumors measuring 2 cm (risk ratio [RR], 4.9; 95%CI, 1.3-16.4; P = 0.019) and subcapsular location (RR, 5.2; 95%CI, 1.7-16.6; P = 0.005) were associated independently with local recurrence. The other four factors were not associated with local recurrence in this study. CONCLUSIONS: A single session, single application of RF ablation produced favorable local control.

Factors that predict intrahepatic recurrence of hepatocellular carcinoma in 81 patients initially treated by percutaneous ethanol injection.

BACKGROUND: In Japan, where liver transplantation has not been used to treat patients with hepatocellular carcinoma (HCC), percutaneous ethanol injection (PEI) has been employed for those with small HCCs that are not amenable to surgical resection. In the current study, the authors evaluated PEI as a treatment for HCC patients by studying recurrence rates and survival after treatment. They then examined the clinicopathologic factors that predicted patterns of local and distant intrahepatic recurrence. METHODS: For 81 patients who underwent PEI as initial therapy between 1990 and 1997, the cumulative recurrence and survival rates and their correlations with 16 clinicopathologic factors were studied using the Kaplan-Meier method. RESULTS: The 3-year overall cumulative rates of intrahepatic recurrence and survival were 81% and 84%, respectively. At the end of the observation period, intrahepatic recurrence was detected in 56 patients (69%). In 21 (38%) of 56 patients, local recurrences were significantly associated with earlier stages of underlying cirrhosis, decreased indocyanine green retention at 15 minutes (ICG R15), larger tumor size, and histologically advanced tumor grade. Distant intrahepatic recurrence was also significantly associated with liver function and ICG R15. CONCLUSIONS: PEI is most effective as the initial treatment for patients with well-differentiated HCC when the tumor is less than 15 mm in greatest dimension. However, local recurrence depends predominantly on the biologic characteristics of the tumor, regardless of the efficacy of PEI. Surgical resection of HCC should be considered, especially for patients with mild liver dysfunction.     

Endoscopic radiofrequency ablation for liver metastasis of colorectal cancer

The application of radiofrequency ablation (RFA) for liver metastasis of colorectal cancer has not yet acquired an established status in clinical cancer therapy research. Removing as much tumor tissue as possible is desirable, but some cases do not allow optimal surgical ablation due to general condition of the patient and tumor status. We introduced endoscopic RFA for liver cancer in 2003, and have applied the procedure to 6 cases with H1 or H2 liver metastases of colorectal cancer to which surgical ablation could not be applied due to the poor general health of patients. Mean tumor diameter was 22.9 mm, and mean number of tumors per patient was 1.2. Tumor location was: S4, n = 2; S5, n = 1; S4, n = 1; S7, n = 2; and S8, n = 1. Mean frequency of session was 3.0. No complications occurred in any cases, and no reoperations were required. Although no recurrence of tumors in the vicinity of ablation was observed, 2 cases of each lung metastasis and intrahepatic recurrence were identified. Intrahepatic recurrence underwent hepatic arterial infusion (HAI) chemotherapy for simultaneous metastatic hepatic tumors (H2) prior to RFA, and relapses occurred in the metastatic focus where the efficacy of HAI was observed. At this point, 2 deaths were reported, 1 each from cancer and other diseases, and mean duration of survival after the procedure was 451.2 days. These results indicate that endoscopic RFA with good local control should be an available treatment for cases involving colorectal cancer with metastasis to the liver in which surgical ablation is difficult to apply.     

CT引导下经皮穿刺射频消融治疗特殊部位肝癌

目的 探讨CT引导下经皮穿刺射频消融（RFA）治疗特殊部位肝癌（直径≤3cm）的疗效及安全性。方法 回顾性分析2008年5月至2012年4月行CT引导下经皮穿刺RFA治疗47例肝癌患者,共消融63个特殊部位（指距离大血管、大胆管或肝外脏器5mm以内）病灶。所有患者术后均行增强CT复查及随访,统计肿瘤完全坏死率、肿瘤局部进展率、肿瘤肝内新生率、生存率及并发症。结果 所有患者均成功接受经皮穿刺RFA治疗。RFA术后1个月特殊部位肝癌完全坏死率为88.89％（56／63）;RFA术后3、6、12个月及1年以上的肿瘤局部进展率分别为4.77％（3／63）、3.17％（2／63）、3.17％（2／63）、1.59％（1／63）,肿瘤肝内新生率分别为15.87％（10／63）、4.76％（3／63）、12.70％（8／63）、3.17％（2／63）。至随访截止时间,47例患者的1、3、5年生存率分别为82.98％（39／47）、63.83％（30／47）、36.17％（17／47）。RFA术后,未出现任何严重并发症,6例（12.77％）出现肝包膜下少量血肿,10例（21.28％）术后发热,经对症处理后症状改善。结论 CT引导下经皮穿刺RFA治疗特殊部位肝癌是安全、有效的方法。     

Needle track seeding after percutaneous radiofrequency ablation of hepatocellular carcinoma: 14-year experience at a single centre

Purpose: To determine the incidence, risk factors and prognosis associated with needle track seeding after percutaneous radiofrequency ablations (RFA) for hepatocellular carcinoma (HCC) with a long-term follow-up.

Materials and methods: A total of 741 HCC patients undergoing percutaneous RFA were retrospectively analysed. Mean follow-up interval was 34.3?±?26.8 months. All seeding neoplasms were diagnosed by imaging modalities with or without pathological evaluation. Risk factors, including Child–Pugh grading, tumour size, number, location, serum alpha-fetoprotein (AFP) level, track number, biopsy before RFA and electrode type were performed by univariate analysis. Further therapy and survival of seeding after RFA were assessed. Survival analysis was analysed by Kaplan–Meier method.

Results: Twelve patients (12 tumours) were diagnosed as seeding. It corresponds to an incidence of 1.6% (12/741) per patient and 0.9% (12/1341) per tumour. Seeding developed an average of 14.0?±?8.1 months (6–33 months). Significant risk factors included tumour >3?cm (p?=?0.031), subcapsular tumour (p?=?0.031), biopsy before RFA (p?=?0.001) and non-cool-tip electrode (p?=?0.034). Eight patients received local therapy and four cases only received systematic therapy for uncontrolled advanced hepatic tumour or distal metastasis. Of eight patients receiving local therapy, one patient had local recurrence 16 months later and other seven patients did not have local recurrence for 3–73 months. The cumulative survival rates after seeding were 55.6%, 27.8%, 9.3% at 1, 3 and 5 years, respectively.

Conclusion: Needle track seeding is a rare delayed complication after percutaneous RFA. Tumour >3?cm, subcapsular tumour, biopsy before RFA and non-cool-tip electrode are potential risk factors for seeding. Local therapies are effective methods for seeding patients.

目的：探讨经导管肝动脉化疗栓塞（TACE）联合序贯射频消融术（RFA）治疗大肝癌患者的疗效及复发因素。方法：选取我院2013年1月－2015年1月肿瘤外科中晚期原发性大肝癌患者110例并分为肝动脉化疗栓塞组（TACE 组）与肝动脉化疗栓塞联合序贯经皮射频消融术组（TACE ＋RFA 组）各55例,TACE 组患者行一次或多次单一肝动脉化疗治疗;TACE ＋RFA 组在肝动脉化疗治疗结束后1～2周再行序贯经皮射频消融术治疗。结果：TACE 组与 TACE ＋RFA 组总有效率分别为63．64％（35／55）、94．54％（52／55）。TACE ＋RFA 组1年生存率为72．7％（40／55）,2年生存率为20．0％（11／55）,而 TACE 组分别为56．36％（31／55）、7．27％（4／55）。Log －rank 检验结果显示肿瘤数量、分期、血清甲胎蛋白水平等为大肝癌患者预后的因素,与患者预后有一定关系。结论：经导管肝动脉化疗栓塞（TACE）联合经皮射频消融术（RFA）治疗原发性中晚期大肝癌可以有效提高患者生存率,延长患者的生存期。肿瘤数量、直径、分期等是影响患者复发的危险因素。     

经皮肝穿刺无水酒精瘤内注射治疗原发性小肝癌的意义

Objective To evaluate the therapeutic effects of percutaneous ethanol intratumoral injection (PEIT) for treatment of small primary liver cancer (SPLC). Methods 240 patients with surgically or pathologically proved SPLC (<3 cm in diameter) were treated by PEIT (under the guidance of B-ultrasound). Of the 240 patients, 163 had recurrent liver cancer, 55 had inoperable liver cancer because of cardiac, pulmonary, hepatic and renal dysfunctions or due to the close proximity of tumor to the major vessels, and 22 refused to receive surgical resection. In 40 patients who received surgical resection after PEIT treatment, the resected tumors were pathologically evaluated for necrotic status and the patients were followed up postoperatively. Results Postoperative 1-, 2- and 3-year survival rate of the 240 patients was 94.9%, 84.2% and 66.3% respectively. Conclusion PEIT can be used as a non-invasive treatment for SPLC, and preoperative PEIT appears to be helpful in reducing recurrence of postoperative liver cancer.
