Factors predictive for long-term survival of male patients with hepatocellular carcinoma after curative resection

BACKGROUND AND OBJECTIVES: Curative hepatic resection (CHR) was a modality that provides possibility of long-term survival for hepatocellular carcinoma (HCC). So far, prognostic factors of male patients with HCC after CHR remain unclear. Purposes of the present study were to identify these factors and to compare them with those for females. METHODS: Consecutive 151 male and 23 female patients with HCC undergoing CHR were enrolled in this retrospective study. Their prognostic factors were identified by uni- and multi-variate statistical analysis. RESULTS: One-, three- and five-year overall and disease-free survival of male patients were 82.4, 51.5, and 43.6%, and 65.8, 33.7, and 21.7%, respectively, with no significant differences compared to females. Univariate analysis showed that tumor size, TNM staging, Edmondson-Steiner grade, serum alpha-fetoprotein (AFP) level, presence of portal vein tumor thrombosis (PVTT) and satellite nodule were significant for males with HCC, but only Edmondson-Steiner grade, presence of PVTT and satellite nodule were independent. For females, Edmondson-Steiner grade was the single potential indicator for survival. CONCLUSIONS: Malignant degree and invasive phenotypes were main factors that independently influenced survival of male patients with HCC after CHR. Among them, histological grade, which was also potentially significant for females, was the most powerful survival predictor.     

肝癌肝移植的预后因素分析

背景与目的：肝移植（liver transplantation,LT）是目前治疗肝细胞癌（hepatocellular carcinoma,HCC）最好的措施,但影响HCC肝移植预后的主要因素和手术指征始终存在争议。明确影响预后的主要因素有助于确定合理的手术指征,进而提高HCC肝移植的生存率。本研究旨在探讨影响HCC肝移植预后的主要因素。方法：回顾性分析1999年2月至2004年12月在四川大学华西医院施行肝移植的98例HCC患者的临床资料和随访结果。用Kaplan—Meier法计算全组的累积生存率,log-rank检验做单因素分析,Cox比例风险回归模型进行多因素分析。结果：全组随访1—78个月,中位随访时间37．6个月;随访期间死亡31例（31．6％）,51例复发（52．0％）。全组病例1年、3年和5年累积生存率分别为84．9％、49．3％和33．2％。单因素分析显示,肿瘤大小、门静脉癌栓（portal vein tumor thrombus．PVTT）、AFP水平、pTNM分期和组织学分级与预后有关：Cox回归多因素分析显示,肿瘤大小和PVTT是影响预后的独立因素。结论：肿瘤大小和PVTT是影响HCC肝移植预后的最主要因素。     

经肝动脉化疗栓塞联合射频消融治疗原发性肝细胞癌合并门静脉癌栓的预后影响因素分析

背景与目的：经肝动脉化疗栓塞（transcatheter arterial chemoembolization,TACE)是否为治疗原发性肝细胞癌（hepatocellular carcinoma,HCC）合并门静脉癌栓（portal vein tumor thrombus,PVTT）的绝对禁忌,目前尚无定论。该研究旨在探讨TACE联合射频消融（radiofrequency ablation,RFA）治疗HCC合并PVTT的预后影响因素。方法：回顾性分析2011年1月1日—2013年12月31日于郑州大学附属肿瘤医院行TACE联合RFA治疗的HCC合并PVTT的157例患者的临床资料及随访数据,单因素及多因素Cox回归分析人口学资料、实验室指标及临床资料与生存时间和肿瘤转移复发情况的关系。结果：多因素Cox回归结果显示,在调整和控制其他因素后,血清白蛋白（albumin,ALB）水平为TACE联合RFA治疗后HCC合并PVTT患者3年生存及降低肿瘤复发转移风险的保护性因素,术前甲胎蛋白（alpha-fetoprotein,AFP）、丙氨酸转氨酶（alanine aminotransferase,ALT）、天门冬氨酸转氨酶（aspartate transaminase,AST）水平、门静脉癌栓部位及肝功能Child Pugh分级为患者3年生存的独立危险因素;AFP、AST水平及门静脉癌栓部位为肿瘤复发转移的独立危险因素。结论：TACE联合RFA并非治疗HCC合并PVTT的绝对禁忌,在治疗前对患者进行相关因素评估有助于更好地选择治疗方法和时机,从而提高HCC治疗水平。

Long-term prognosis in hepatocellular carcinoma patients after hepatectomy

Background: The hepatocellular carcinoma is very common in China. Our aim in this report was to investigate clinical and pathological factors based on the current decade data that could influence prognosis of HCC patients after hepatectomy. Methods: Between 2002 and 2009, all patients undergoing hepatectomy for HCC were followed up and reviewed retrospectively. Prognostic factors were studied by univariate and multivariate analysis, with Kaplan-Meier and Cox multivariate survival analyses. Results: Complete clinicopathologic and follow-up data were available for 114 patients. The estimated cumulative survival rates at 1, 3, and 5 yr were 84.6%, 60.2% and 51.8%, respectively. On univariate analysis, key prognostic factors were AFP level, GGT level, tumor size, number of tumors, portal vein invasion, liver cirrhosis status and TNM stage. In the multivariate analysis, tumor size, GGT level, liver cirrhosis status and portal vein invasion were significantly associated with patients’ prognosis. Conclusion: Through follow-up of a relatively large cohort of Chinese patients, tumor size, GGT level, liver cirrhosis status, portal vein invasion were revealed as important factors for long-term survival after hepatectomy. Early diagnosis for tumor and the improvement of liver function before surgery are important ways to improve the prognosis.     

Prognostic Significance of Preoperative Serum Alphafetoprotein in Hepatocellular Carcinoma and Correlation with Clinicopathological Factors: a Single-center Experience from China

Objectives: To investigate the prognosis significance of preoperative serum alpha-fetoprotein (AFP) andthe correlation with clinicopathological factors of hepatocellular carcinoma (HCC) patients who underwenthepatectomy. Materials and Methods: Clinicopathological data of retrospective analysis were collected for251 HCC patients undergoing hepatectomy in this study. According to preoperative AFP level, patients werecategorized into AFP-negative (0-20ng/mL) and AFP-positive (>20 ng/mL) groups for Kaplan-Meier analysisand Cox proportional hazard regression modeling. Results: The results demonstrated that increased AFPwas associated with longer prothrombin time (PTs), liver capsule invasion, low grade differentiation, and lateBarcelona Clinic Liver Center (BCLC) stage. Moreover, the female patients had a greater prevalence of increasedpreoperative AFP than male patients [284.8 (3.975-3167.5) vs (3.653-140.65); Z-2.895, p=0.004]. The 1-, 3-, and5-year recurrence-free survival (RFS) rates were 78.1, 57.5, and 40.6 % in the AFP-negative group and 61.8,37.7, and 31.4 %, respectively, in the AFP-positive group (log-rank test 8.312, p=0.004). The 1-, 3-, and 5-yearoverall survival (OS) rates were 94.4, 83.8, and 62.3% in the AFP-negative group and 87.2, 60.0, and 36.7%,respectively, in the AFP-positive group. The difference was statistically significant (log-rank test, 16.884, p=0.000).Cox proportional-hazards model identified preoperative AFP to be an independent prognostic predictor of overallsurvival. Conclusions: Preoperative serum AFP is an independent predictor of prognosis among HCC patientsfollowing surgical resection. Female patients have a higher preoperative AFP than their male counterparts.     

Clinicopathological features, post-surgical survival and prognostic indicators of elderly patients with hepatocellular carcinoma.

AIM: Comprehensive data regarding elderly patients with hepatocellular carcinoma (HCC) were limited. The present study aims to widen the knowledge based on patients in China. METHODS: Fifty-four elderly (> or =65 years) and 125 non-elderly HCC patients undergoing hepatectomy were enrolled in this retrospective study. Clinicopathological features and post-surgical survival were compared between two groups. Prognostic indicators of elderly patients were defined by uni- and multivariate analyses. RESULTS: Contrast to non-elderly patients, the elderly presented significantly lower rates of HBsAg positivity, Child-Pugh grade A, alpha-fetoprotein (AFP) marked elevation, portal vein tumour thrombosis (PVTT), satellite nodule, and intrahepatic recurrence, smaller tumour sizes, earlier TNM staging and better histological differentiation. No significant differences were found in perioperative mortality rate and post-surgical survival between two groups. PVTT and Edmondson-Steiner grading were identified as independent prognostic indicators of both overall and disease-free survival by multivariate analysis, whereas Child-Pugh grading independently affected the overall survival. CONCLUSIONS: HCC in the elderly seemed to be less HBV-associated, less progressive and less aggressive than that in the non-elderly. Hepatectomy for the elderly could make a satisfactory prognosis and be well tolerated. Some tumour-related factors independently predict the prognosis of elderly HCC patients, and their liver function status should be further valued.     

Selective prognostic impact of serum alpha-fetoprotein level in patients with hepatocellular carcinoma: analysis of 543 patients in a single center

The prognostic impact of serum alpha-fetoprotein (AFP) level in patients with hepatocellular carcinoma (HCC) is controversial. This study aimed to investigate the predictive ability of serum AFP in HCC patients. A total of 543 patients undergoing surgical resection (258 patients) and non-surgical treatment (285 patients) including transarterial chemoembolization and percutaneous injection therapy were retrospectively studied. Overall, AFP level >400 ng/ml was an independent poor prognostic predictor [relative risk (RR): 1.4, 95% confidence interval (CI): 1.0-1.9, p=0.049]. Stratified analysis showed that there was a sharp contrast of predictive power of AFP level in treatment strategy and tumor size. In surgical patients, serum AFP >400 ng/ml was a tumor size-independent predictor of tumor recurrence (RR: 1.7, 95% CI: 1.2-2.5, p=0.006) and survival (RR: 2.3, 95% CI: 1.3-3.8, p=0.002). However, there was no association between AFP level and survival in the non-surgical group (p=0.597). Alternatively, among the 157 patients with large (>5 cm) HCCs, AFP >400 ng/ml independently predicted a poor survival (RR: 1.9, 95% CI: 1.2-2.5, p=0.012), whereas no clear relationship between AFP level and survival was found among the 386 patients with small (< or =5 cm) HCCs (p=0.685). There was no differential prognostic impact of serum AFP levels in other variables. In conclusion, serum AFP level is a weak prognostic predictor in HCC patients. Its predictive ability is highly selective and dependent on treatment strategy and tumor size. Incorporation of serum AFP level into any prognostic prediction model should be based on its distinctive selective prognostic power.     

Elevated preoperative aspartate aminotransferase to lymphocyte ratio index as an independent prognostic factor for patients with hepatocellular carcinoma after hepatic resection

Few studies have elucidated the relationship between preoperative aspartate aminotransferase (AST) to lymphocyte ratio and high incidence of hepatocellular carcinoma (HCC). In search of a simple non-invasive prognostic marker, we investigated the prognostic significance of AST to lymphocyte ratio index (ALRI) in HCC. We reviewed retrospectively clinical parameters of 371 HCC patients who were treated with hepatectomy. Receiver operating characteristic (ROC) curve analysis was performed to determine the cut-off value of preoperative ALRI. The predictive value of preoperative ALRI in HCC was evaluated by univariate and multivariate analyses using Cox proportional hazards regression modeling, and the survival probability of HCC patients was acquired by the Kaplan-Meier plots. In addition, stratified analysis was used to investigate the impact of preoperative ALRI on survival in different HCC subgroups. The results showed that preoperative ALRI was closely correlated with age (p = 0.007), median size (p = 0.004), clinical tumor-node-metastasis (TNM) stage (p < 0.001), and portal vein tumor thrombosis (PVTT) (p < 0.001). Survival analysis indicated that HCC patients with preoperative ALRI > 25.2 have a poorer disease-free survival (DFS) and overall survival (OS) after tumor resection. Multivariate analysis further identified preoperative ALRI > 25.2 (p = 0.002), III-IV of TNM stage (p = 0.011), PVTT (p = 0.035), size of tumor > 5 cm (p < 0.001) as independent risk factors of DFS; and preoperative ALRI > 25.2 (p = 0.001), III-IV of TNM stage (p = 0.005), PVTT (p = 0.012), size of tumor > 5 cm (p < 0.001), recurrence (p < 0.001) as independent prognostic factors for OS in HCC patients. Additionally, preoperative ALRI also showed different prognostic value in various subgroups of HCC. Elevated preoperative ALRI as a noninvasive, simple, and easily assessable parameter is an independent effective predictor of prognosis for patients with HCC.
