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.     

Clinically significant portal hypertension (CSPH) on early-stage HCC following hepatectomy: What's the impact?

Background and aimThe impact of currently clinically significant portal hypertension (CSPH) for patients with early-stage HCC after surgery remains controversial. The purpose of this study is to understand the specific effect of CSPH on patients with early-stage (BCLC A stage) HCC after surgery.MethodsWe collected data from 386 HCC patients treated at two centers from December 2009 to January 2017.224 patients (all treated by hepatectomy) were in BCLC stage A, of which, 122 had no CSPH, and 102 had CSPH. There were 162 patients in BCLC stage B (who underwent surgery, TACE, and conservative treatment). The prognosis of the CSPH and non-CSPH groups in BCLC stage A was compared using the Kaplan-Meier method. We used multivariate Cox regression to analyze prognostic factors in patients in BCLC stage A and compared the prognosis of the two groups with the BCLC stage B group.ResultsAmong the 224 BCLC stage A patients after surgery, the overall survival (OS) and recurrence-free survival (RFS) of the CSPH group were worse than those of the non-CSPH group (P < 0.001, HR = 2.340[1.554–3.523]; P < 0.001, HR = 2.577[1.676–3.812]) The multivariate Cox proportional hazards model indicated that CSPH was an independent prognostic factor for OS and RFS in BCLC stage A patients. BCLC stage A patients with CSPH treated by hepatectomy had a comparable prognosis to BCLC B stage patients (P = 0.378), and the OS and RFS (P = 0.229; P = 0.077) in the CSPH (BCLC A) group were also comparable to BCLC stage B patients treated with surgery alone.ConclusionsCSPH can affect the surgical prognosis of early-stage (BCLC stage A) HCC. BCLC stage A patients with CSPH have a prognosis comparable to patients with BCLC stage B. An additional stage, such as the BCLC stage A-B, can be considered.     

Prognostic factors of hepatic resection for hepatocellular carcinoma with cirrhosis: univariate and multivariate analysis

BACKGROUND AND OBJECTIVES: The objective of this investigation was to study the clinicopathological factors influencing long-term outcome of hepatocellular carcinoma (HCC) with liver cirrhosis in patients undergoing hepatectomy. Liver cirrhosis, especially the macronodular variety, has been found in up to 90% of patients with HCC. In Asia, the incidence of liver cirrhosis in patients with HCC who had undergone hepatic resection varies from 42.5% to 73.8%. However, the optimal surgical approach for HCC patients with cirrhosis is less clearly defined. Resection of the cirrhotic liver is challenging and remains controversial in the treatment of HCC. METHODS: This study retrospectively analyzed the surgical outcomes of HCC concomitant with liver cirrhosis in 218 patients who underwent hepatic resection between 1986 and 1998. Post-resection prognostic factors were assessed using a univariate log-rank test and a multivariate Cox proportional hazards model. RESULTS: The overall postoperative complication rate was 15.6%, while the surgical mortality rate was 8.8%. Meanwhile, the 1-, 3-, and 5-year disease-free survival rates were 50.9%, 33.98%, and 27.03%, respectively, and. the overall cumulative survival rates at 1, 3, and 5 years were 63.14%, 41.88%, and 31.83%, respectively. Applying Cox's multivariate proportional hazard model indicated that significant adverse prognostic indicators included elevated alkaline phosphatase value, tumor size >2 cm, presence of satellite lesions, and vascular invasion. CONCLUSIONS: This investigation found that overall survival for HCC patients concomitant with liver cirrhosis who underwent hepatic resection should be stratified on the basis of the high value of alkaline phosphatase, tumor size, satellite lesions, and vascular invasion.     

Validation of The Hong Kong Liver Cancer Staging System in Patients with Hepatocellular Carcinoma after Curative Intent Treatment

Backgrounds: Recently Hong Kong Liver Cancer (HKLC) staging system has been proposed for staging of hepatocellular carcinoma (HCC), and has been shown to provide better prognostic ability than the Barcelona Clinic Liver Cancer (BCLC) system. However, the HKLC system lacks external validation, and its applicability remains uncertain. The present study was aimed to evaluate the prognostic performance of HKLC in HCC patients treated with curative intent. Methods: Medical records of HCC patients treated with either resection or radiofrequency ablation (RFA) from 2011 to 2016 were retrospectively reviewed. The overall survival and the prognostic ability of the HKLC and BCLC system were evaluated. Results: 79 HCC patients were included, of which 64.56% had Child A cirrhosis. Chronic viral hepatitis B infection was the leading cause of HCC, followed by chronic viral hepatitis C infection, alcohol and alcohol with HBV or HCV infection. According to the BCLC system, 82.28% were in stage 0-A, and according to the HKLC system, 93.67% were in stage I-IIb. RFA and liver resection were the primary treatment in 56.96% and 43.04%, respectively. The 5-year survival rate of patients in HKLC stage I, IIa and IIb were 81.64%, 61.66%, and 54.42%, respectively (P<0.001). Whereas, the 5-year survival rate of patients in BCLC stage 0, A and B were 60.00%, 75.90%, and 26.65%, respectively (P=0.053). The AUROC curve of the HKLC and BCLC for the entire cohort was 0.77 and 0.64, respectively (P=0.15). Subgroup analysis showed the AUROC curve of the HKLC and BCLC for the patients with viral-associated HCC was 0.79 and 0.68, respectively (P=0.02). Conclusions: Applying the HKLC staging system provides a good discriminative ability for survival prediction in HCC patients treated with curative intent. Comparing with the BCLC system, the HKLC system tends to yield better prognostic accuracy, particularly in viral-associated HCC.

残癌危险因素对肝癌切除术后肝动脉栓塞化疗效果的影响

目的 探讨术后辅助性肝动脉栓塞化疗对残癌低危和残癌高危患者预后的不同影响。方法 进入研究的病例分为干预组(辅助性动脉栓塞化疗组)和对照组(未行辅助性动脉栓塞化疗),根据残癌的高危因素将肝癌切除术的患者分为残癌高危者和残癌低危者,采用病例对照实验设计,以单因素统计方法和Cox模型,分析研究术后辅助性肝动脉栓塞化疗对肝癌切除术患者预后的影响,以及残癌高危因素对辅助性动脉栓塞化疗作用的影响。结果 对于残癌低危患者,干预组和对照组术后1,2,3,4年生存率分别为97．2％、78．0％、66．5％、66．5％和91．2％、81．4％、70．3％、54．4％,生存率差异无显著性(P=0．7667);而对于残癌高危患者,干预组和对照组术后1,2,3,4年生存率分别为89．5％、73．4％、59．2％、53．8％和70．5％、61．9％、46．8％、46．8％,生存率差异有显著性(P=0．0029)。Cox比例风险模型分析结果显示,辅助性动脉栓塞化疗对切除术后肝癌患者预后的影响,决定于患者有无残癌的危险因素,辅助性动脉栓塞化疗不是影响患者预后的独立因素。结论 术后给予辅助性肝动脉栓塞化疗,可延长有残癌高危因素患者的生存期,而对于无残癌危险因素的患者,术后辅助性肝动脉栓塞化疗不能延长生存期。     

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.
