Serum high-density lipoprotein cholesterol levels predict early recurrence and prognosis of intrahepatic cholangiocarcinoma after surgical resection.

Introduction: Dysregulation in lipid metabolism contributes to the occurrence and development of various cancers. The connection between changes in lipid metabolism and the development of intrahepatic cholangiocarcinoma remains uncertain. Our objective was to investigate the significance of blood lipid levels in patients with intrahepatic cholangiocarcinoma who have undergone surgery. Methods: Ninety-seven ICC patients who underwent surgery were retrospectively enrolled. After 92.2 months of follow-up, the Kaplan-Meier analysis and Cox proportional hazard model were used to calculate overall survival and recurrence-free survival. Results: The median age of this cohort was 56 years, and 79 (81.4 %) of them were male. Eighty-eight (90.7 %) patients presented with tumor recurrence and 73 (75.3 %) died. In multivariate analyses, high-density lipoprotein cholesterol level (<0.91 vs. ≥ 0.91 mmol/L, hazard ratio [HR] = 2.55; 95 % CI: 1.38-4.71), lymph node metastasis (Yes vs. No, HR = 2.58; 95 % CI: 1.28-5.19), etiology factor (chronic HBV infection vs. others, HR = 0.5; 95 % CI: 0.28-0.88) and multiple tumor lesions (Yes vs. No, HR = 1.85; 95 % CI: 1.01-3.39) were independent predictors of overall survival. However, only high-density lipoprotein cholesterol level (HR = 1.86; 95 % CI: 1.19-2.92) emerged as the independent factor for recurrence-free survival. High-density lipoprotein cholesterol level (HR = 2.07; 95 % CI: 1.26-3.41), etiology factor (HR = 0.49; 95 % CI: 0.29-0.84), and multiple tumor lesions (HR = 2.00; 95 % CI: 1.14-3.51) were independent predictors of early recurrence. For patients who did not experience the spread of cancer to the lymph nodes, there was a significant correlation between the level of high-density lipoprotein cholesterol and their overall survival, recurrence-free survival, and early recurrence. For patients with low pre-operation high-density lipoprotein cholesterol levels, high post-operation high-density lipoprotein cholesterol levels were associated with better prognosis. Conclusions: Low serum high-density lipoprotein cholesterol level might serve as a sign of poor clinical outcomes (overall survival and recurrence-free survival) and early recurrence among intrahepatic cholangiocarcinoma patients. Strengthening the monitoring and intervention of intrahepatic cholangiocarcinoma patients with poor prognosis might be critical for improving the prognosis.

Influence of weight management on the prognosis of steatohepatitis in chronic hepatitis B patients during antiviral treatment.

BACKGROUND: Although concomitant nonalcoholic steatohepatitis (NASH) is common in chronic hepatitis B (CHB), the impact of viral factors on NASH and the outcome of CHB patients concomitant with NASH remain unclear. We aimed to investigate the outcomes of NASH in CHB patients receiving antiviral treatment. METHODS: In the post-hoc analysis of a multicenter trial, naïve CHB patients receiving 72-week entecavir treatment were enrolled. We evaluated the biochemical, viral and histopathological responses of these patients. The histopathological features of NASH were also evaluated, using paired liver biopsies at baseline and week 72. RESULTS: A total of 1000 CHB patients were finally enrolled for analysis, with 18.2% of whom fulfilling the criteria of NASH. A total of 727 patients completed entecavir antiviral treatment and received the second biopsy. Serum HBeAg loss, HBeAg seroconversion and HBV-DNA undetectable rates were similar between patients with or without NASH (P > 0.05). Among patients with NASH, the hepatic steatosis, ballooning, lobular inflammation scores and fibrosis stages all improved during follow-up (all P < 0.001), 46% (63/136) achieved NASH resolution. Patients with baseline body mass index (BMI) ≥ 23 kg/m2 (Asian criteria) [odds ratio (OR): 0.414; 95% confidence interval (95% CI): 0.190-0.899; P = 0.012] and weight gain (OR: 0.187; 95% CI: 0.050-0.693; P = 0.026) were less likely to have NASH resolution. Among patients without NASH at baseline, 22 (3.7%) developed NASH. Baseline BMI ≥ 23 kg/m2 (OR: 12.506; 95% CI: 2.813-55.606; P = 0.001) and weight gain (OR: 5.126; 95% CI: 1.674-15.694; P = 0.005) were predictors of incident NASH. CONCLUSIONS: Lower BMI and weight reduction but not virologic factors determine NASH resolution in CHB. The value of weight management in CHB patients during antiviral treatment deserves further evaluation.

On-treatment monitoring of liver fibrosis with serum hepatitis B core-related antigen in chronic hepatitis B.

BACKGROUND: Non-invasive evaluation for liver fibrosis is clinically important, especially in patients with undetectable hepatitis B virus (HBV) DNA treated with nucleoside analogs. AIM: To clarify the monitoring power of hepatitis B core-related antigen (HBcrAg) for hepatic histologic changes in patients with chronic hepatitis B (CHB) treated with entecavir. METHODS: This prospective multicenter study used multiple ordinal and multivariate logistics regression analysis to assess variables associated with Ishak fibrosis score and regression for fibrosis regression, respectively, in 403 CHB patients, including 374 with entecavir for 72 weeks (291 underwent paired liver biopsy) and 29 as controls. RESULTS: Level of HBcrAg correlated negatively with liver fibrosis staging (γ = -0.357, P < 0.001) in hepatitis B e antigen (HBeAg)-positive patients, and positively with liver fibrosis staging in HBeAg-negative patients. Higher HBcrAg concentration was associated with younger age, HBeAg positive status, high HBV DNA loads, high level of hepatitis B surface antigen (HBsAg) and higher necroinflammation, but not with HBV genotype. Serum concentration of HBcrAg, basal core promoter/precore (BCP/PC) mutant, quantitation of HBsAg (qHBsAg) and platelet counts were independently associated with Ishak fibrosis score on multiple ordinal regression. HBV DNA was undetectable in 88.37% of patients treated with entecavir at week 72, while their level of HBcrAg was still detectable. A greater reduction in post-treatment HBcrAg concentration was associated with the regression of hepatic fibrosis and histological improvement. HBcrAg concentration > 6.33 log IU/mL at baseline and logarithmic reduction > 1.03 log IU/mL at week 72 were associated with a higher chance of regression of liver fibrosis and histological improvement, respectively. CONCLUSION: HBcrAg level is associated with liver fibrosis progression. HBcrAg is an excellent monitor of hepatic histological changes, especially in CHB patients treated with nucleoside analogs.

Self-expandable metallic stent as a bridge to elective surgery versus emergency surgery for acute malignant colorectal obstruction.

BACKGROUD: The efficacy and safety of self-expandable metallic stents (SEMSs) as a bridge for patients with acute malignant colorectal obstructions (AMCOs) are still controversial. We conducted this study to evaluate the outcomes of patients with AMCOs treated by different strategies. METHODS: From January 2010 to March 2014, a total of 171 patients with AMCOs from Zhongshan Hospital were retrospectively enrolled in this study. One hundred twenty patients successfully received stent placement followed by one-stage laparoscopic or open resection in the stent group, and 51 patients received emergency operations in the emergency group. RESULTS: The operation duration and postoperative hospital stay were significantly shorter in the stent group (114.51 ± 28.65 vs. 160.39 ± 58.94 min, P < 0.001; 8.00 ± 3.97 vs. 12.59 ± 9.07 days, P = 0.001). The stent group also had significantly reduced intraoperative blood loss and the incidence of postoperative complications compared with the emergency group (61.00 ± 43.70 vs. 121.18 ± 85.90 ml, P < 0.001; 16.7 vs. 37.3%, P = 0.003). Kaplan-Meier survival curves showed that the median survival time in the stent group was significantly longer than that in the emergency group (53 vs. 41 months, P = 0.034). In subgroup analysis of stent group, the stent laparoscopy group had significantly decreased postoperative complications (P = 0.025), and similar long-term survival (P = 0.81). CONCLUSIONS: Stent placement as a bridge to surgery is a safe and feasible procedure and provides significant advantages in terms of short-term outcomes and favorable prognoses for patients with AMCOs. Laparoscopic surgery could be considered as an optimal treatment after stent placement.

[Optimization of alcohol precipitation technology of Biqiu granules based on index components and pharmacodynamics].

To evaluate the rationality of alcohol precipitation technology of Biqiu granule by investigating its effect on serum histamine, IgE, IL-4, IFN and TNF-α. The contents of cafferic acid and rosmarinic acid were used as the evaluation indexes, and some factors affecting index were firstly evaluated by Plackett-Burman design; then alcohol precipitation technology was further optimized by Box-Behnken design to determine the optimal alcohol precipitation conditions. The best alcohol precipitation conditions were as follows: the relative density of herb liquor was 1.15 (65 ℃); the concentration of alcohol was 70%, and standing time was 12 hours. Optimal alcohol precipitation technology of Biqiu granules determined by pharmacodynamic screening, Plackett-Burman and Box-Behnken design tests, was stable and feasible with good predictability, providing reliable basis for the industrialization production of Biqiu granules.

Antiviral effects of Reduning injection against Enterovirus 71 and possible mechanisms of action.

The present study was designed to evaluate the protective effects of Reduning injection against Enterovirus 71 (EV71) in Vero cells and in mice. The Vero cells were infected with 100 and 50 TCID50 (50% tissue culture infective dose) of EV71, respectively. The inhibition of Reduning injection on cytopathic effect (CPE) was detected. Meanwhile, a mouse model produced by intraperitoneal EV71-infection (10(6) TCID50), was used to investigate the protective effects of Reduning injection. The total survival rate, living time, daily survival rate, weight ratio, and score for symptoms were examined. The viral loads in Vero cells and muscle tissues were detected using real-time PCR. Finally, the content of cytokines was analyzed by ELISA. In the Vero cells, 2.5 mg crude drug·mL(-1) of Reduning injection inhibited CPE induced by EV71 infection. In the mice, 1.3 g crude drug·kg(-1) of Reduning injection rescued death triggered by infection, in comparison with model group. Moreover, the survival rate, weight ratio, and clinical scores were also improved. The viral RNA copies in the Vero cells and the mice muscle tissues were reduced. Besides, the steep EV71-induced accumulations of TNF-α and MCP-1 were decreased by Reduning injection. In conclusion, Reduning injection showed promising protective effects against EV71 in Vero cells and in mice.

Hepatic angiomyolipoma mimicking hepatocellular carcinoma: magnetic resonance imaging and clinical pathological characteristics in 9 cases.

Hepatic angiomyolipoma (HAML) is a rare mesenchymal tumor of the liver with marked histological diversity. The present study was to review the magnetic resonance imaging (MRI) and clinical pathological features of HAML resembling hepatocellular carcinoma (HCC). Nine patients who underwent surgical resection and had pathological diagnosis of HAML were retrospectively analyzed. All of 9 patients (5 males and 4 females) had a solitary hepatic mass with a median size of 4 cm (from 1.4 cm to 15.3 cm). Seven cases were identified as incidental liver tumors during health screening and 2 patients were diagnosed for hepatic mass when visited hospitals with unspecific abdominal discomfort. Before resection, 6 cases were diagnosed as HCC on MRI. MRI on chemical shift imagings showed a large amount of lipids in 5 cases. The enhancement pattern of MRI was classified into 2 types: in 2 cases, lesions with small or no vessels that demonstrated prolonged enhancement (1 mixed subtype and 1 myomatous subtype) and in 7 cases, lesions with abundant central vessels that show rapid washout (3 mixed subtypes and 4 myomatous subtypes) in the portal venous/delayed phase. All patients underwent resection of hepatic tumor and no recurrence was observed during follow-up (range: 2-24 months) of median 10 months. By immunohistochemistry, the tumor cells demonstrated positive immunostaining for human melanoma black-45, smooth muscle actin, and CD34. In conclusion, all of 9 patients with HAML presented with none or nonspecific clinical manifestations. The diagnosis of HAML relies on disease and immunohistochemistry, but not MRI due to its resemblance to HCC.

[Effects of guizhi fuling capsule on sex hormone levels and breast issue morphology of mammary gland hyperplasia model rats].

OBJECTIVE: To research the effects of Guizhi Fuling capsule on sex hormones levels in blood serum and breast issue morphology of hyperplasia of mammary glands model rats. METHOD: The unpregnancy SD rat models of hyperplasia of mammary glands were established by injecting 0.5 mg x kg(-1) benzoate estradiol. After five weeks doses,the effects of Guizhi Fuling capsule 2.0, 1.0, 0.5 g x kg(-1) and Rupixiao tablet 0.5 g x kg(-1) on the changes of papilla diameter, height and breast issue morphology of the naimal models were explored, and sex hormones levels in blood serum were measured. RESULT: Guizhi Fuling capsule can inhibitnipple swell, improve breast tissue morphology pathological profiles of the animal models, and decrease oestradiol (E2) level and increase progesterone (P) level in blood serum. CONCLUSION: These results suggested that Guizhi Fuling capsule could, improve mammary gland pathological profiles. Regulating sex hormone levels may be its important mechanism for treatment of hyperplasia of mammary glands.

Hypomethylation of long interspersed nuclear element-1 promoter is associated with poor outcomes for curative resected hepatocellular carcinoma.

BACKGROUND: Epigenetic alterations are well documented in hepatocarcinogenesis. However, hypomethylation of long interspersed nuclear element 1(LINE-1) promoter and its relationship with clinicopathological features in hepatocellular carcinoma(HCC) remain unknown. METHODS: The bisulfite-specific PCR and DNA sequencing analysis was performed to assess the methylation status of LINE-1 promoter in a pilot cohort of 71 patients with HCC. Additionally,methylation levels of two hot CpG sites of LINE-1 promoter, site 7 and 18 were measured by real-time PCR and compared with clinicopathological parameters in a cohort of 172 HCC. All the patients included were in BCLC stage A or B. RESULTS: Most patients with HCC (87.3%) showed hypomethylation of LINE-1 promoter compared with HBV-related cirrhosis and normal controls (P < 0.001). The HCC patients with LINE-1 promoter hypomethylation had a median tumour-free survival (TFS) and overall survival (OS)post-resection of 22.0 (95% CI: 13.3­30.7) months and 35.0 (95% CI: 24.0­46.1) months, respectively, compared with 40 months and ~60 months for those with LINE-1 promoter hypermethylation (P < 0.05). Multivariate analyses showed that the hypomethylation level at CpG site 7 and 18 of LINE-1 promoter, along with tumour size and tumour differentiation, was independently associated with both TFS and OS for patients with HCC after resection. CONCLUSION: Promoter hypomethylation of LINE-1, especially at the CpG site 7 and 18, was associated with a poor prognosis in HCC.

Long interspersed nuclear element ORF-1 protein promotes proliferation and resistance to chemotherapy in hepatocellular carcinoma.

AIM: To clarify the specific roles and mechanisms of long interspersed nuclear element-1 ORF-1 protein [human long interspersed nuclear element-1 (LINE-1), ORF-1p] in chemotherapeutic drug resistance and cell proliferation regulation in hepatocellular carcinoma (HCC) cells. METHODS: MTT assays were performed to identify the effect of the chemotherapeutic drug toxicity on HepG2 cells. Cell proliferation inhibition and the IC50 were calculated by the Origin 8.0 software. Western blotting assays were performed to investigate whether LINE-1 ORF-1p modulates the expression of some important genes, including p53, p27, p15, Bcl-2, mdr, and p-gp. To corroborate the proliferation and anchor-independent growth results, the HepG2 cells were analyzed by flow cytometry to investigate the effect of LINE-1 ORF-1p on the apoptosis regulation. RESULTS: LINE-1 ORF-1p contributed to the resistance to several chemotherapeutic drugs (cisplatin and epirubicin) in HepG2 cells. The IC50 of the epirubicin and cisplatin increased from 36.04 nmol/L to 59.11 nmol/L or from 37.94 nmol/L to 119.32 nmol/L. Repression of LINE-1 ORF-1p expression by the siRNA could markedly enhance the response of HepG2 cells to the epirubicin and cisplatin. The IC50 correspondingly decreased from 28.06 nmol/L to 3.83 nmol/L or from 32.04 nmol/L to 2.89 nmol/L. Interestingly, down-regulation of LINE-1 ORF-1p level by siRNA could promote the response of HepG2 cells to the paclitaxel. The IC50 decreased from 35.90 nmol/L to 7.36 nmol/L. However, overexpression of LINE-1 ORF-1p did not modulate the paclitaxel toxicity in HepG2 cells. Further Western blotting revealed that LINE-1 ORF-1p enhanced mdr and p-gp gene expression. As a protein arrested in the nucleus, LINE-1 ORF-1p may function through modulating transcriptional activity of some important transcription factors. Indeed, LINE-1 ORF-1p promoted HepG2 cell proliferation, anchor-independent growth and protected the cells against apoptosis through modulating the expression of p15, p21, p53, and Bcl-2 genes. CONCLUSION: LINE-1 ORF-1p promotes HepG2 cell proliferation and plays an important role in the resistance of chemotherapeutic drugs. By establishing novel roles and defining the mechanisms of LINE-1 ORF-1p in HCC chemotherapeutic drug resistance and cell proliferation regulation, this study indicates that LINE-1 ORF-1p is a potential target for overcoming HCC chemotherapeutic resistance.

High intratumoral metastasis-associated in colon cancer-1 expression predicts poor outcomes of cryoablation therapy for advanced hepatocellular carcinoma.

BACKGROUND: Cryoablation is one of the local therapies for hepatocellular carcinoma (HCC), but its safety and effect has not been studied in patients with Child class A or B and Barcelona Clinic Liver Cancer (BCLC) stage C HCC. Metastasis-associated in colon cancer-1 (MACC1) overexpression has been associated with poor prognosis of HCC, but its predictive value to post-cryoablation outcomes remains unknown in patients with BCLC stage C HCC. METHODS: This study assessed the safety and outcomes of cryoablation measured by time to progression (TTP) and overall survival (OS), and predictive value of MACC1 mRNA and protein overexpression in tumorous tissue to post-cryoablation outcomes in 120 advanced HCC patients with child-pugh class A or B by quantitative polymerase chain reaction and immunohistochemical staining. The potenial correlation of MACC1 and c-Met expression to tumor cell proliferation and apoptosis was also analyzed. RESULTS: The cryoablation in patients with advanced unresectable HCC resulted in a median TTP and OS of 5.5 (4.2- 6.7) months and 10.5 (9.0-12.0) months, respectively and no significant complications, comparable to the historical report for RFA therapy. The MACC1 mRNA and nuclear protein expression was significantly increased in tumorous tissues in these patients than that in normal liver tissue controls. Higher expression of MACC1 mRNA and nuclear protein in tumorous tissues in these patients was associated with shorter post cryoablation median TTP and OS than that with lower MACC1 expression. CONCLUSIONS: Cryoablation is a safe and effective therapeutic option for patients with advanced HCC and Child-pugh class A or B cirrhosis; and a higher intratumoral expression of MACC1 or nuclear translocation predicts poor outcomes of cryotherapy in these patients.

Overexpression of metastasis-associated in colon cancer 1 predicts a poor outcome of hepatitis B virus-related hepatocellular carcinoma.

AIM: To investigate the intratumoral expression of metastasis-associated in colon cancer 1 (MACC1) and c-Met and determine their clinical values associated with hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). METHODS: A retrospective study admitted three hundred fifty-four patients with HBV-related HCC. The expression and distribution of MACC1 and c-Met were assessed by quantitative real-time polymerase chain reaction and immunohistochemistry staining. Prognostic factors influencing survival, metastasis and recurrence were assessed. RESULTS: Intratumoral MACC1 level was found to be associated with HCC disease progression. Both median tumor-free survival (TFS) and overall survival (OS) were significantly shorter in the postoperative HCC patients with high intratumoral MACC1 expression, as compared to those with low intratumoral MACC1 levels (TFS: 34 mo vs 48.0 mo, P < 0.001; OS: 40 mo vs 48 mo, P < 0.01). Multivariable analysis indicated that high MACC1 expression or co-expression with c-Met were independent predictors for HCC clinic outcome (P < 0.001). CONCLUSION: High intratumoral MACC1 expression can be associated with enhanced tumor progression and poor outcome of HBV-related HCC. MACC1 may serve as a prognostic biomarker for postoperative HCC.

Decrease in size of non-treated lesions after cryoablation for hepatocellular carcinoma.

We present the case of one 58-year-old man with advancd hepatocellular carcinoma and hepatitis-B virus-related liver cirrhosis who received hepatic cryoablation. Magnetic resonance imaging (MRI) showed multiple liver tumors and the diameter of the largest tumor was more than 10cm. The patient received 2 percutaneous cryoablations in December 2009 and January 2010. Ten months later, MRI showed that not only the treated areas underwent necrosis but also the non-treated area decreased. The a-fetoprotein (AFP) level and the frequency of circulated regulatory T cell (Treg) before treatment were 13,800ng/mL and 15.6%, respectively. Following the cryoablations they dropped to 436ng/mL and 7.6%, respectively, 10 months later. The patient remains in good condition until now.

[Expression and clinical significance of metastasis-associated in colon cancer 1 (MACC1) in HBV-related hepatocellular carcinoma].

OBJECTIVE: To clarify the expression and clinical significance of metastasis-associated in colon cancer 1 (MACC1) mRNA in hepatocellular carcinoma (HCC). METHODS: The expression and distribution of MACC1 were assessed by quantitative real-time polymerase chain reaction (RT-PCR) and immunohistochemical staining (IHC) in a cohort of hepatitis B virus-related HCC, including 138 in early (A), 96 in intermediate (B) and 120 in advanced stages (C). The association of MACC1 mRNA with disease progression and outcomes was analyzed by univariate and multivariate Cox analysis. RESULTS: The intratumoral expressions of MACC1 mRNA in HCC stage I (0.001 76, range: 0.000 54 - 0.002 47), stage II (0.002 49, range: 0.000 55 - 0.006 78) and stage III (0.008 35, range: 0.006 86 - 0.009 88) were about 3-, 4- and 14-fold higher than that in the normal liver tissue (0.000 59, range: 0.000 57 - 0.000 60), respectively. Intratumoral expression of MACC1 mRNA increased with disease progression from stage I to stage III. HCC clinical staging classification, age, portal vein invasion and tumor differentiation were significantly associated with intratumoral high expression of MACC1 mRNA (All P < 0.05). Immunohistochemical staining showed that there was an increased MACC1 expression in cytoplasm of HCC cells and positive nuclear staining in some cases. Increased MACC1 mRNA expression could predict poor outcome and recurrence in stage A and B HCC postoperatively. The median tumor-free survival and total survival of patients with high MACC1 mRNA expression were 34.0 and 40 months, respectively, significantly lower than that in those with low expression (48.0 and 48.0 months) (all P < 0.01). Cox analysis showed that Child-Pugh grading and high expression of MACC1 mRNA were independent predictive factors, and high expression of MACC1 was an independent predictive factor affecting the tumor-free survival. CONCLUSIONS: MACC1 mRNA up-regulation is a feature of disease progression in HCC. MACC1 mRNA expression in the HCC may become an independent predictive factor for recurrence and survival in postoperative HCC patients.

Upregulation of circulating PD-L1/PD-1 is associated with poor post-cryoablation prognosis in patients with HBV-related hepatocellular carcinoma.

BACKGROUND: The programmed cell death-1 receptor/programmed cell death-1 ligand (PD-1/PD-L1) pathway plays a crucial role in tumor evasion from host immunity. This study was designed to evaluate the association between circulating PD-L1/PD-1 and prognosis after cryoablation in patients with HBV-related hepatocellular carcinoma (HCC). METHODOLOGY/PRINCIPAL FINDINGS: In the present study, 141 HBV-related HCC patients were enrolled and of those 109 patients received cryoablation. Circulating PD-L1/PD-1 expression was tested by flow cytometry, and 23 patients were simultaneously evaluated for intratumoral PD-L1 expression by immunohistochemical staining. Circulating PD-1/PD-L1 expression was associated with severity of diseases in patients with HCC, and the circulating PD-L1 expression was closely correlated with intratumoral PD-L1 expression. Of the clinical parameters, PD-1/PD-L1 expression was associated with tumor size, blood vessel invasion and BCLC staging. Moreover, PD-1/PD-L1 expression dropped after cryoablation while being elevated at the time of tumor recurrence. Patients with higher expression of circulating PD-L1, as well as circulating PD-1, had a significantly shorter overall survival and tumor-free survival than those with lower expression. Multivariate analysis confirmed that circulating PD-L1 could serve as an independent predictor of overall survival and tumor-recurrence survival in HCC patients after cryoablation. CONCLUSIONS/SIGNIFICANCE: Upregulation of circulating PD-L1/PD-1 is associated with poor post-cryoablation prognosis in patients with HBV-related hepatocellular carcinoma.

[Clinical efficacy and prognostic factors for cryoablation patients with advanced hepatocellular carcinoma].

OBJECTIVES: Investigate the clinical efficacy of cryotherapy ablation treatment for advanced hepatocellular carcinoma. analyse the predictive factors of cryotherapy ablation treatment. METHODS: There were 190 cases of hepatitis B-related HCC patients with advanced HCC from 2005 to 2008 in our hospital. By using clinical cohort method, they included cryoablation group (147 cases) and control group (43 cases), The median survival time and time to disease progression were compared. Evaluate clinical significance of age, gender, location of portal vein tumor thrombus, HBeAg, tumor histological grade, Child-Pugh classification, end-stage liver disease (MELD) score, advanced liver cancer prediction system (ALCPS) score and the Eastern Cooperative Oncology Group performance status (ECOG PS) score for predicting the efficacy of cryoablation. Group rates were compared with the x2 test, survival analysis by using Kaplan-Meier method, survival rates were compared by Log-rank analysis; multiple factor survival analysis by using Cox regression model. RESULTS: Median survival time of cryoablation group and Control group was 7.5 (4.2 to 14.6) months and 3.2 (1.2 to 8.6) months, median TTP was 3.5 (2.5 to 4.5) months and 1.5 (1.0 to 3.5 months), the differences were statistically significant ( P less than 0.05 ). Median OS and TTP of advanced HCC patients who had Well-differentiated tumor, Child-pugh A-class and low score of MELD score, ALCPS score, ECOG PS score were significantly longer than the poorly differentiate, Child-Pugh B-class and the high those scores ( P less than 0.05). ECOG PS ( P less than 0.05, 95% CI 1.074 to 2.143) and ALCPS (P less than 0.05, 95% CI 1.005 to 2.121) were independent predictors for OS of advanced HCC. CONCLUSION: Cryoablation treatment can prolong median OS and TTP of advanced HCC; ECOG PS and ALCPS are important predictors for survival time of advanced HCC.
