    ABSTRACT: Radical lymph node dissection in surgery for advanced gallbladder cancer is controversial. The purpose of this study is to evaluate the different extent of lymph node dissection for N2 stage gallbladder cancer patients. A retrospective analysis was made of 60 patients with N2 stage who underwent standard regional lymphadenectomy (SRLN) and extended regional lymphadenectomy (ERLN). Between September 2000 and June 2011, 60 advanced gallbladder cancer patients with N2 stage of lymph node metastasis were included in this study. The curative effects with different extent of lymphadenctomy for lymph node N2 stage of gallbladder cancer patients were compared. The median survival time was 34.83 months in the SRLN group and 30.28 months in the ERLN group. There was no significant difference of survival rate between SRLN and ERLN group (P=0.51). Postoperative major morbidity and mortality rates were 64.3% and 7.14% in the SRLN group, 81.3% and 9.34% in the ERLN group, respectively. Moreover, the number of positive lymph nodes and chemotherapy were found to correlate with survival on univariate analyses (P<0.05). For advanced gallbladder patients with N2 stage lymph node metastasis, ERLN cannot provide a significant survival benefit over SRLN and the rate of morbidity and mortality in ERLN is exceptionally high. ERLN therefore should not be considered in the advanced gallbladder cancers with N2 stage.

    ABSTRACT: Adjuvant interferon (IFN) therapy following curative treatment for hepatocellular carcinoma (HCC) has been extensively investigated; however, the clinical benefits with different hepatitis backgrounds remain unclear. Medline, Embase, PubMed and the Cochrane Library databases were searched to identify randomized trials and cohort studies that enrolled HCC patients who received curative surgery or ablation therapy followed by IFN and control subjects; the studies were required to include data on early or late recurrence and mortality rates of HCC. Hepatitis B virus (HBV) associated with HCC (HBV-HCC) and hepatitis C virus (HCV) associated with HCC (HCV-HCC) were separately analyzed and recurrence, mortality and clinicopathological factors were compared. A total of 14 studies (9 randomized trials and 5 cohort studies, including 1,385 patients in total) were eligible for meta-analysis. IFN was found to decrease mortality and early recurrence rates, but exerted no effect on late recurrence rate. The effect of IFN differed between HBV-HCC and HCV-HCC cases. In HCV-HCC, IFN significantly reduced mortality as well as recurrence rates. However, in HBV-HCC patients, IFN reduced mortality rather than recurrence rates, although it also reduced the recurrence rate in certain subgroups. In conclusion, the effect of adjuvant IFN on postoperative recurrence differed between HBV-HCC and HCV-HCC cases; therefore, different strategies with adjuvant IFN should be used to treat HCC with different hepatitis backgrounds.

    ABSTRACT: This study aimed to investigate the clinical utility of simultaneous measurement of alphafetoprotein (AFP) and des-γ-carboxy prothrombin (DCP) for hepatocellular carcinoma (HCC) diagnosis in Chinese patients predominantly caused by hepatitis B virus infection by a multi-center case-controlled study. Subjects were 1,153 individuals from three major hospitals in China, including 550 cases in HCC group, 164 in Malignant disease group, 182 in Benign disease group, 85 in Chronic liver disease group, and 173 in Normal group. Serum levels of AFP and DCP were measured and clinicopathological features were determined for all subjects. Results showed that the levels of DCP and AFP were significantly higher in HCC group (550 patients, 74.18% with HBV infection) than that in other four groups (P < 0.001). Receiver operating curves (ROC) indicated the optimal cut-off value was 86 mAU/mL for DCP with a sensitivity of 71.50% and specificity of 86.30%, and 21 ng/mL for AFP with a sensitivity of 68.00% and specificity of 93.20%. The area under ROC curve was 0.846 for DCP, 0.832 for AFP, and 0.890 for the combination of DCP and AFP. The combination of DCP and AFP resulted in a higher Youden index and a sensitivity of approximately 90%, even for small tumors. The simultaneous measurement of AFP and DCP could achieve a better sensitivity in diagnosing Chinese HCC patients, even for small tumors.

    ABSTRACT: Wnt5a, p-JNK and p-paxillin proteins have been shown to be associated with the development of several types of cancer. Here we studied the role of Wnt5a, p-JNK and p-paxillin protein expressions and functions in the further development of pancreatic adenocarcinoma. Fresh tissue samples from adjacent and malignant portions were obtained after operation from 58 patients with pancreatic adenocarcinoma. Wnt5a, p-JNK1, JNK1, paxillin and p-paxillin were detected with immunohistochemical staining. The expressions of Wnt5a, p-JNK1 and p-paxillin were higher in malignant tissues than in adjacent portions (p < 0.01), where JNK1 and paxillin were absent (p > 0.05). The expression levels of Wnt5a, p-JNK1 and p-paxillin in tumor tissues were correlated with each other (r = 0.564, 0.586 and 0.737, respectively). The expression of Wnt5a in tumor tissue could independently predict the occurrence of lymph node involvement [odds ratio (OR) 8.19, 95 % confidence interval (CI) 2.47-27.19]. The expression of p-JNK1 in tumor tissue was an independent predictor of peritoneal metastasis (OR 4.01, 95 % CI 1.32-12.17). Wnt5a/JNK signaling might be activated in pancreatic cancer. Wnt5a is the specific predictor for lymph node involvement.

    ABSTRACT: Expression of WNT5A associated with aggressive tumor biology and poor clinical outcome of various types of cancer. However its function in the metastasis property of pancreatic cells still needs to be elucidated. We detected the expressions of WNT5A, JNK1/p-JNK1 and Paxillin/p-Paxillin in cancer and the para-carcinoma tissues of pancreatic cancer. To understand how WNT5A/JNK signaling affects pancreatic cancer cell migration through the phosphorylation of cellular substrates of Paxillin, In vitro, we knocked down the WNT5A in PANC1, Capan-2 and HT1080 cell lines, and then tested the expression of JNK1. We detected the proteins of phosphorylation of Paxillin after JNK1 was inhibited and then the cells migration assay was evaluated. Moreover, JNK1 functionally phosphorylates serine178 on paxillin in vitro was detected .At last we subsequently observed whether WNT5A/JNK signaling modulates some molecule expressions relevant to focal adhesion (FA) formation and mesenchymal transition (EMT) and cell cycle. WNT5A, p-JNK1 and p-Paxillin were highly expressed in early stage of tumor tissues. In vitro, WNT5A/JNK signaling promotes cell migration in pancreatic cancer by phosphorylating serine178 on Paxillin, an FA adaptor, which means WNT5A may regulate FA's function.WNT5A up-regulates the molecule's expressions relevant to cell adhesion through the phosphorylation of JNK1, including MMP1, MMP2, ICAM and CD44. In addition, WNT5A/JNK signaling promoted the mRNA expressions of vimentin, but decreased in E-Cadherin expression, which suggested its regulatory effects on the EMT processes. WNT5A/JNK signaling didn't modulate cell proliferation. WNT5A/JNK signaling initiate cell migration of pancreatic cancer through activation of Paxillin, which suggested WNT5A has the potency of being an effective therapeutic target for the metastasis of pancreatic cancer.

    ABSTRACT: Non-parasitic hepatic cysts with biliary communication are rare. The clinical symptoms involved are not specific to this condition, thereby making diagnosis difficult and treatment controversial. Here, we report a case of 70-year-old woman complaining of abdominal satiety, combined with non-specific pain in the right upper quadrant. The abdominal contrast-enhanced MRI-scan revealed a large and thick-walled septus cystic lesion in the liver. During operation, the biliary fistula was confirmed in the cyst cavity. A silica gel tube was inserted via the cystic duct for cholangiography, which demonstrated communication between the cyst and biliary tract. We performed wide-scale cyst wall resection; the biliary fistula was completely repaired by the closure of communicated bile ducts. The postoperative course was uneventful, and the patient was discharged with no sign of cholangitis or any other symptoms. The novel surgical management via wide resection of the cyst wall and closure of biliary communication proved to be an adequate and effective procedure for treating nonparasitic hepatic cysts with biliary communication.

    ABSTRACT: Objective: This work aimed to investigate the correlations of tumor-associated macrophages (TAMs) and their subtypes M1 and M2 with liver metastasis of colorectal cancer, and provide useful references for seeking predictors of liver metastasis and studying mechanisms. Methods: 120 patients with colorectal cancer from 2000 to 2009 were divided into low, middle and high liver metastasis groups (group A, B and C, respectively). S-P immunohistochemical staining and microscopic observation were conducted to compare expression in CD68- positive cells (TAMs), CD80-positive cells (M1) and CD163-positive cells (M2) in three groups. Correlations of TAMs, M1, M2, and M2/M1 ratio with clinical and pathological parameters were analyzed. Results: With increase of liver metastatic ability, the number of TAMs decreased gradually, with no significant difference between any two of the three groups (P > 0.05), while the numbers of M1 and M2 were significantly decreased and increased, respectively, with significant difference between any two of three groups (P < 0.05 or P < 0.01). In addition, the M2/M1 ratio increased with increase of liver metastatic ability (P < 0.01). There was no statistical significance of correlation of TAMs with each clinical and pathological parameter. M1 was negatively related with lymphatic metastasis and liver metastatic ability. M2 was positively correlated with preoperative CEA level, lymphatic metastasis, tumor differentiation degree and liver metastatic ability. The same was the case for the M2/M1 ratio. Conclusions: Effects of TAMs on liver metastasis of colorectal cancer do not depend on the total number of TAMs, but on the number and proportion of functional subtypes M1 and M2. M2 number and M2/ M1 ratio are more accurate predictors for liver metastasis of colorectal cancer.

    ABSTRACT: Obesity is rapidly becoming pandemic and is associated with increased carcinogenesis, especially hepatocellular carcinoma (HCC). Adipose tissue is considered as an endocrine organ because of its capacity to secrete a variety of adipokines, such as leptin, adiponectin and resistin. Recently, adipokines have been demonstrated to be associated with kinds of chronic liver diseases including fibrosis, cirrhosis and carcinogenesis. Direct evidence is accumulating rapidly supporting the inhibitory and/or activating role of adipokines in the process of carcinogenesis and progression of human HCC. This review aims to provide important insight into the potential mechanisms of adipokines in the development of HCC.

    ABSTRACT: OBJECTIVES: The aim of this study was to determine if there has been improvement in survival for patients with gallbladder cancer treated with surgical procedures. METHODS: A retrospective review of all patients with gallbladder cancer admitted during the past 11 years was conducted. The patients were categorized into two periods: period 1, from 1 January 2000 to 31 December 2005 (group 1, n = 77); and period 2, from 1 January 2006 to 31 December 2010 (group 2, n = 131). RESULTS: The two groups have similar age, sex distribution, and symptoms. There were more patients with advanced stage in group 2 (P = 0.001). And patients in group 2 were treated with more aggressive surgical procedures compared with group 1. Patients of group 2 had a better surgical outcomes and longer 5-year overall survival (9 % vs. 19 %, P = 0.040) and disease-free survival (P = 0.017). Median survival in group 1 was 14.7 months, while in group 2 it was 22.3 months. Patients underwent R0 resection in group 2 had better survival than that in group 1 (P = 0.009), while they had similar survival for those who underwent non-R0 resection in both periods (P = 0.108). CONCLUSIONS: A significant improvement of disease-free survival and long-term survival results was observed in the past decade.

    ABSTRACT: To explore the efficacy of hepatic resection (HR) in a relatively unselected group of patients with ovarian cancer liver metastases (OCLM). A study was conducted between September 2000 and September 2011 on 60 ovarian cancer patients with hepatic metastases (24 solitary and 36 multiple), 40 of whom had extrahepatic metastases. HR was done in all patients provided that curative hepatic resection was feasible, and extrahepatic disease was controlled with medical and/or surgical therapy. Most patients (n=54; 90.0%) had a negative hepatic margin (R0), whereas 6 patients (10.0%) had microscopic disease at the margin (R1). The prognostic value of each study variable was assessed using log rank tests for univariate analysis and Cox proportional hazard models for multivariate analysis. The result was a median survival of 39 months and 5-year overall survival rate of 30%. Univariate analysis showed that surgery result (P=0.001), disease free interval (P=0.018) and the number of hepatic lesions (P=0.018) were significantly related to survival. Furthermore, the surgery result (P=0.004) remained significant for prognosis in multivariate analysis. For patients with OCLM, HR is safe and may provide a significant survival benefit compared with medical therapy alone. A long interval time, the number of hepatic lesions, and surgery results are key prognostic factors. Favorable outcomes can be achieved even in patients with medically controlled or surgically resectable extrahepatic disease, indicating that surgery should be considered more frequently in the multidisciplinary care of patients with OCLM.

    ABSTRACT: BACKGROUND & AIMS: Antiangiogenic agents can sometimes promote tumor invasiveness and metastasis, but little is known about the effects of the antiangiogenic drug sorafenib on progression of hepatocellular carcinoma (HCC). METHODS: Sorafenib was administered orally (30 mg · kg(-1) · day(-1)) to mice with orthotopic tumors grown from HCC-LM3, SMMC7721, or HepG2-wt cells. We analyzed survival times of mice, along with tumor growth, metastasis within liver and to lung, and induction of the epithelial-mesenchymal transition. Polymerase chain reaction arrays were used to determine the effects of sorafenib on gene expression patterns in HCC cells. We analyzed regulation of HIV-1 Tat interactive protein 2 (HTATIP2) by sorafenib and compared levels of this protein in tumor samples from 75 patients with HCC (21 who received sorafenib after resection and 54 who did not). RESULTS: Sorafenib promoted invasiveness and the metastatic potential of orthotopic tumors grown from SMMC7721 and HCC-LM3 cells but not from HepG2 cells. In gene expression analysis, HTATIP2 was down-regulated by sorafenib. HCC-LM3 cells that expressed small hairpin RNAs against HTATIP2 (knockdown) formed less invasive tumors in mice following administration of sorafenib than HCC-LM3 without HTATIP2 knockdown. Alternatively, HepG2 cells that expressed transgenic HTATIP2 formed more invasive tumors in mice following administration of sorafenib. Sorafenib induced the epithelial-mesenchymal transition in HCC cell lines, which was associated with expression of HTATIP2. Sorafenib regulated expression of HTATIP2 via Jun-activated kinase (JAK) and signal transducer and activator of transcription (STAT)3 signaling. Sorafenib therapy prolonged recurrence-free survival in patients who expressed lower levels of HTATIP2 compared with higher levels. CONCLUSIONS: Sorafenib promotes invasiveness and the metastatic potential of orthotopic tumors from HCC cells in mice, down-regulating expression of HTATIP2 via JAK-STAT3 signaling.

    ABSTRACT: The aim of this study was to define the clinical features and surgical treatment outcomes of patients with primary hepatic angiosarcoma. Data of the 6 patients diagnosed with primary hepatic angiosarcoma in Tianjin Medical University Cancer Institute and Hospital from January 1999 to December 2005 were retrospectively reviewed. The median age of the patients was 49 years (range 45-78 years) with a male predominance. Laboratory tests showed a mild elevation of α-fetoprotein in 2 patients, and 2 had both hepatitis B and C. Liver resection was performed in all patients. For the 5 patients who received curative liver resection, the median follow-up duration was 41 months (range 23-84 months) and the overall 1-year, 3-year and 5-year survival rates were 100.0%, 80.0% and 40.0%, respectively. One patient who underwent a palliative operation died of tumor progression a month after operation. Early diagnosis is necessary and complete surgical resection is the key to improve prognosis.

    ABSTRACT: PURPOSE: To evaluate clinical outcomes associated with single-session, whole-liver radioembolization with Yttrium-90 (90Y)-labeled resin microspheres in patients with nonresectable liver metastases from breast cancer that were refractory to other treatments. METHODS: A retrospective analysis of consecutive patients who were treated between January 2002 and October 2008 was performed. Fifty-eight patients with unresectable liver metastases from breast cancer who had a good performance status and a low burden of extrahepatic disease were eligible for RE. Patients had undergone polychemotherapy regimens including at least anthracyclines and taxanes, hormonal therapy, and trastuzumab were applicable. RESULTS: A median activity of 1.93 GBq of 90Y was delivered. Follow-up at a median of 4.2 months demonstrated complete response, partial response, stable disease, and progressive disease in 5, 52, 31, and 12 % of patients, respectively. With respect to tumor diameters, imaging revealed a maximum and minimum response of -57.6 to +25.8 %, respectively. The median overall survival was 12.3 months. The median survival of responders and nonresponders was 20.9 and 6.3 months, respectively, and the median survival of patients with and patients without extrahepatic disease was 8.3 and 16.2 months, respectively. Clinically significant toxicities with the appearance of increasing transaminase level, increasing bilirubin level, nausea and vomiting, gastric ulcers, and ascites. CONCLUSIONS: Single-session, whole-liver 90Y radioembolization can be performed with an acceptable toxicity profile in patients with liver metastases from breast cancer.

    ABSTRACT: To analyze our experience and the surgical and survival outcomes of patients with pancreatic carcinoma who underwent pancreaticoduodenectomy (PD) by analysis of a retrospective cohort of 205 patients over a 10 years period. The patients were categorized into two 5-year periods: period 1, from 2000 January 1 to 2004 December 31(group 1, n = 48) and period 2, from 2005 January 1 to 2009 December 31(group 2, n = 157). We analysis the data using statistical software and find the improvement of surgical and survival outcomes of PD for pancreatic cancer in the past 10 years. The two groups have similar age, sex distribution, comorbidity, preoperative serum tumor markers, patients number of preoperative biliary drainage and postoperative chemotherapy. More patients in group 2 underwent lymph nodes dissection (P = 0.031). And patients of group 2 had a better surgical outcomes and longer 5-year overall survival (8% vs. 19%, P = 0.036). The blood loss volume, transfusion volume, and the number of patients need blood transfusion were significantly fewer (P < 0.001) for the patients in group 2, however, the operation time was obviously lengthened (P = 0.002). Patients in Group 1 suffered more postoperative complications than those of the patients in group 2 (P = 0.021). A significant difference was reached for survival between the two group (P = 0.036). A significant improvement of surgical and survival outcomes after PD for pancreatic cancer patients was achieved in the past 10 years. PD remains the only treatment option that potentially provides a cure for pancreatic head cancer, and postoperative chemotherapy may produce survival benefit.

    ABSTRACT: Astragalus polysaccharides (APS), the main active extract from Astragalus membranaceus (a traditional Chinese medicinal herb), is associated with a variety of immunomodulatory activities. The purpose of the present study was to examine the effect of APS on the function of Treg cells in the tumor microenvironment of human hepatocellular carcinoma (HCC) and to identify the pharmacologic mechanism of APS responsible for the anti-chemotactic activity in CD4+CD25highTreg cells in tumor site of HCC. The prevalence of Treg in fresh tissue samples from 31 patients with HCC after radicalhepatectomy was detected. CD4, CD25 and CD127 were selected as Treg cell makers to phenotype cell populations. The expression of FOXp3 mRNA was also analyzed. The migration and proliferation of Treg cells were observed. Interleukin (IL)-4, IL-10, IFN-γ and SDF-1 in cell supernatant were detected. For all tests, functions of Treg cells were evaluated after treatment with APS. APS can inhibit the growth and proliferation of CD4+CD25+Treg cells in vitro in a dose- and time-dependent manner. APS may inhibit CD4+CD25+Treg cells through restoring the cytokine imbalance and reducing the expression of FOXp3 in local HCC microenvironments. SDF-1 played an important role in there recruitment of Treg cells into the tumor microenvironment of HCC. APS might have inhibiting effects on Treg cell migration by blocking SDF-1 or its receptor through the CXCR4/CXCL12 pathway. The increase in numbers of tumor associated Treg cells might play a role in modulation of the immune response against HCC. APS can restore the cytokine balance in the tumor micro environment and suppress the expression of FOXp3 mRNA to inhibit the immune suppressive effects of Treg cells. The application of APS in the tumor microenvironment might act to enhance the anti-tumor effects of the immunotherapy-based methods, and consequently to increase the survival rate in HCC.

    ABSTRACT: Aim:  To compare the surgical treatment outcomes between patients with colorectal liver metastases (CLM) and non-colorectal liver metastases (NCLM). Methods:  The study population consisted of 132 patients undergoing hepatectomy at Tianjin Medical University Cancer Hospital between January 1996 and December 2008. Survival analyses were used to assess the differences in prognosis and survival between groups. Results:  The primary tumor site was colorectal in 60 (45.5%), breast in 16 (12.1%), lung in 14 (10.6%), non-colorectal gastrointestinal in 12 (9.1%), genitourinary in 10 (7.6%), pancreatobiliary tumor (n = 8, 6.1%) and others in 12 (9.1%). A curative liver resection was performed in all patients by pathological findings. After a median follow-up of 32 months, the overall 3- and 5-year survival rate was 44.7 and 29.5% in all patients, respectively. The 3- and 5-year survival rates were 53.3 and 36.7% for liver metastases from colorectal tumors, 62.5 and 43.8% from breast, 60.0 and 40.0% from genitourinary neoplasm, 41.7 and 25.0% from non-colorectal gastrointestinal cancer, 28.5 and 15.0% from lung, 12.5 and 0% from pancreatobiliary malignancies, and 41.7 and 8.3% from other sites, respectively. Conclusions:  Hepatic resection is an effective and safe treatment for liver metastases mainly depending on primary tumor sites. Hepatic metastases from non-colorectal gastrointestinal cancer, pulmonary and pancreatobiliary malignancies have the worst prognosis; those from breast and genitourinary neoplasm show the best prognosis.

    ABSTRACT: Histone deacetylases (HDACs) remove acetyl groups from lysine residues of histones and the deacetylation allows for tighter electrostatic interactions between DNA and histones, leading to a more compact chromatin conformation with limited access for transactivators and the suppression of transcription. HDAC mRNA and protein overexpression was observed in endometrial and ovarian cancers. Numerous in vitro studies have shown that HDAC inhibitors, through their actions on histone and nonhistone proteins, are able to reactivate the tumor suppressor genes, inhibit cell cycle progression and induce cell apoptosis in endometrial and ovarian cancer cell cultures. Results from mouse xenograft models also demonstrated the potency of HDAC inhibitors as anticancer reagents when used as single agent or in combination with classical chemotherapy drugs.

    ABSTRACT: BACKGROUND: To determine whether the inferior outcome noted with triple-negative breast cancer (TNBC) reflects a higher risk population among patients with breast cancer liver metastases. METHODS: A total of 123 patients with breast cancer liver metastases diagnosed at Tianjin Medical University Cancer Hospital were included in this study. Breast cancer subtype was assigned using immunohistochemistry or fluorescence in situ hybridization: hormone receptor (HR) positive (+)/human epidermal growth factor receptor 2 (HER2) negative (-), HR+/HER2+, HR-/HER2+ and triple-negative subtype. Clinical features and survival were evaluated in different subtypes. RESULTS: The median age at breast cancer diagnosis was 47 years (range, 23-67 years). Breast cancer subtype was confirmed in all patients (39.8% with HR+/HER2-, 24.4% with HR+/HER2+, 15.3% with HR-/HER2+ and 20.3% with TNBC). The median overall survival after liver metastases was 29 months (range, 4-89 months), and the overall 1-, 2- and 3-year survival rate was 68.3, 48.0 and 34.1%, respectively. Survival was found to be impacted by breast cancer subtype (P = 0.001), and was shortest for patients with TNBC. Time to liver metastases (TTLM) less than 24 months and liver metastasis lesions ≥3 were found to be important predictors of poor survival after liver metastases (P = 0.009 and 0.001, respectively). CONCLUSIONS: The results indicate that clinical breast cancer subtype remains an independent prognostic predictor among patients with breast cancer liver metastases. Liver metastases arising from TNBC confers the worst prognosis, and novel agents capable of controlling intrahepatic and extrahepatic TNBC are needed.
