Prevalence, patterns, risk factors and outcomes of peritoneal metastases after laparoscopic hepatectomy for hepatocellular carcinoma: a multicenter study from China.

Background: We aim to investigate the prevalence, patterns, risk factors, and outcomes of peritoneal metastases (PM) after curative laparoscopic hepatectomy (LH) for hepatocellular carcinoma (HCC). Methods: A multicenter cohort of 2,138 HCC patients who underwent curative LH from August 2010 to December 2016 from seven hospitals in China was retrospectively analyzed. The incidence of PM following LH was evaluated and compared with that in open hepatectomy (OH) after 1:1 propensity score matching (PSM). Results: PM prevalence was 5.1% (15/295) in the early period [2010-2013], 2.6% (47/1,843) in the later period [2014-2016], and 2.9% (62/2,138) in all LH patients, which was similar to 4.0% (59/1,490) in the OH patients. The recurrence patterns, timing, and treatment did not significantly vary between the LH and OH patients (P>0.05). Multivariate logistic regression revealed that tumor diameter >5 cm, non-anatomical resection, presence of microvascular invasion, and lesions <2 cm from major blood vessels were independent risk factors of PM after LH. Of the 62 cases with PM, 26 (41.9%) had PM only, 34 (54.9%) had intrahepatic recurrence (IHR) and PM, and 2 (3.2%) had synchronous extraperitoneal metastases (EPM). Patients with resectable PM had a 5-year overall survival (OS) of 65.0% compared to 9.0% for unresectable PM (P=0.001). Conclusions: The prevalence, patterns and independent risk factors of PM were identified for HCC patients after LH. LH was not associated with increased incidence of PM in HCC patients for experienced surgeons. Surgical re-excision of PM was associated with prolonged survival.

Exploring expectations of Chinese patients for total knee arthroplasty: once the medicine is taken, the symptoms vanish.

BACKGROUND: Preoperative expectations of total knee arthroplasty (TKA) outcomes are important determinants of patient satisfaction. However, expectations of patients in different countries are affected by cultural background. The general goal of this study was to describe Chinese TKA patients' expectations. METHODS: Patients scheduled for TKA were recruited in a quantitative study(n = 198). The Hospital for Special Surgery Total Knee Replacement Expectations Survey Questionnaire was used for survey TKA patients' expectations. Descriptive phenomenological design was used for the qualitative research. Semi-structured interviews were conducted with 15 TKA patients. Colaizzi's method was used for interview data analysis. RESULTS: The mean expectation score of Chinese TKA patients was 89.17 points. The 4 highest score items were walk short distance, remove the need for walker, relieve pain and make knee or leg straight. The 2 lowest score items were employed for monetary reimbursement and sexual activity. Five main themes and 12 sub-themes emerged from the interview data, including multiple factors raised expectations, expectations of physical comfort, expect various activities back to normal, hope for a long joint lifespan, and expect a better mood. CONCLUSIONS: Chinese TKA patients reported a relatively high level of expectations, and differences across cultures result in different expectation points than other national populations, requiring adjustment of items when using assessment tools across cultures. Strategies for expectation management should be further developed. LEVEL OF EVIDENCE: Level IV.

Cidan Capsule in Combination with Adjuvant Transarterial Chemoembolization Reduces Recurrence Rate after Curative Resection of Hepatocellular Carcinoma: A Multicenter, Randomized Controlled Trial.

OBJECTIVE: To evaluate the efficacy and safety of Cidan Capsule combined with adjuvant transarterial chemoembolization (TACE) in patients with a high risk of early recurrence after curative resection of hepatocellular carcinoma (HCC). METHODS: A multicenter, randomized controlled trial was conducted in patients with high-risk recurrence factors after curative resection of HCC from 9 medical centers between July 2014 and July 2018. Totally 249 patients were randomly assigned to TACE with or without Cidan Capsule administration groups by stratified block in a 1:1 ratio. Postoperative adjuvant TACE was given 4-5 weeks after hepatic resection in both groups. Additionally, 125 patients in the TACE plus Cidan group were administrated Cidan Capsule (0.27 g/capsule, 5 capsules every time, 4 times a day) for 6 months with a 24-month follow-up. Primary endpoints included disease-free survival (DFS) and tumor recurrence rate (TRR). Secondary endpoint was overall survival (OS). Any drug-related adverse events (AEs) were observed and recorded. RESULTS: As the data cutoff in July 9th, 2018, the median DFS was not reached in the TACE plus Cidan group and 234.0 days in the TACE group (hazard ratio, 0.420, 95% confidence interval, 0.290-0.608; P<0.01). The 1- and 2-year TRR in the TACE plus Cidan and TACE groups were 31.5%, 37.1%, and 60.8%, 63.4%, respectively (P<0.01). Median OS was not reached in both groups. The 1- and 2-year OS rates in TACE plus Cidan and TACE groups were 98.4%, 98.4%, and 89.5%, 87.9%, respectively (P<0.05). The most common grade 3-4 AEs included fatigue, abdominal pain, lumbar pain, and nausea. One serious AE was reported in 1 patient in the TACE plus Cidan group, the death was due to retroperitoneal mass hemorrhage and hemorrhagic shock, and was not related to study drug. CONCLUSIONS: Cidan Capsule in combination with TACE can reduce the incidence of early recurrence in HCC patients at high-risk of recurrence after radical hepatectomy and may be an appropriate option in postoperative anti-recurrence treatment.

Risk Factors and a New Prediction Model for Pancreatic Fistula After Pancreaticoduodenectomy.

AIM: In order to find the risk factors of postoperative pancreatic fistula (POPF) after pancreaticoduodenectomy (PD) according to the latest definition and grading system of International Study Group of Pancreatic Surgery (ISGPS) (version 2016) and propose a nomogram for predicting POPF. METHODS: We conducted a retrospective analysis of 232 successive cases of PD performed at our hospital by the same operator from August 2012 to June 2020. POPF was diagnosed in accordance with the latest definition of pancreatic fistula from the ISGPS. The risk factors of POPF were analyzed by univariate and multivariate logistic regression analysis. A nomogram model to predict the risk of POPF was constructed based on significant factors. RESULTS: There were 18 cases of POPF, accounting for 7.8% of the total. Among them, 17 cases were classified into ISGPF grade B and 1 case was classified into ISGPF grade C. In addition, 35 cases were classified into biochemical leak. Univariate and multivariate analysis showed that hypertension, non-diabetes, no history of abdominal surgery, antecolic gastrojejunostomy and soft pancreas were independent risk factors of POPF. Based on significant factors, a nomogram is plotted to predict the risk of POPF. The C-index of this nomogram to assess prediction accuracy was 0.916 (P < 0.001) indicating good prediction performance. CONCLUSION: Hypertension, non-diabetes, no history of abdominal surgery, antecolic gastrojejunostomy and soft pancreas were independent risk factors of POPF. Meanwhile, a nomogram for predicting POPF with good test performance and discriminatory capacity was constituted.

Abdominal Pain After Subtotal Gastrectomy: A First Report of Accessory Pancreatic Fistula.

BACKGROUND: The accessory pancreatic duct (APD) is the main drainage duct of the dorsal pancreatic bud in the embryo and varies greatly during development. An APD fistula is a rare and easily neglected complication. In this case report, the first symptom of the patient was postoperative abdominal pain and fever. He was eventually diagnosed with accessory pancreatic fistula combined with duodenal fistula. Such a case has not been reported in the literature. CASE SUMMARY: A 66-year-old man was emergently hospitalized for abdominal pain. His preliminary diagnosis was perforation of the digestive tract. He developed fever and abdominal pain after emergency subtotal gastrectomy, followed by changes in the colour of the abdominal drainage fluid. An APD fistula and duodenal stump fistula were confirmed by drainage fluid amylase analysis, contrast fistulography and percutaneous transhepatic cholangial drainage (PTCD). After PTCD, nutritional management and drug treatment, the patient recovered well. OUTCOME: We found and successfully cured a case of accessory pancreatic duct fistula combined with duodenal stump fistula.

The roles of ARHGAP10 in the proliferation, migration and invasion of lung cancer cells.

Lung cancer is a leading cause of cancer-related mortalities worldwide. In the present study, a comparison of To determine the roles of ARHGAP10 in the proliferation, migration and invasion of lung cancer cells expression levels between normal lung tissues and lung cancer tissues were compared using immunoblotting, and CCK-8 and Transwell assays. Lung cancer tissues had a decreased ARHGAP10 mRNA expression level compared to the adjacent normal tissues. The ectopic expression of ARHGAP10 significantly suppressed the migration, invasion and proliferation of lung cancer cells. Gene set enrichment analysis revealed that metastasis and Wnt signaling pathways were negatively correlated with ARHGAP10 expression. Immunoblotting analysis revealed that ARHGAP10 overexpression inhibited metastasis [matrix metalloproteinase (MMP)-2, MMP-9 and VEGF] and the expression of Wnt pathway-related proteins (ß-catenin and c-Myc). Moreover, the stimulation effects of lithium chloride, a GSK3ß inhibitor, on the accumulation of ß-catenin were notably suppressed by ARHGAP10 overexpression. Collectively, ARHGAP10 acts to suppress tumor within lung cancer by affecting metastasis and Wnt signaling pathways. The results therefore suggest that ARHGAP10 is a potentially attractive target for the treatment of lung cancer.

Curcumin prevents diabetic nephropathy against inflammatory response via reversing caveolin-1 Tyr14 phosphorylation influenced TLR4 activation.

Inflammation is involved in the development and/or progression of diabetic nephropathy (DN). Curcumin has been reported for its anti-inflammation activity in DN. However, the mechanisms involved in the renoprotective effects of curcumin have not been clearly demonstrated. In this study, we hypothesized that curcumin affected high glucose (HG)-induced inflammation profiles in vivo and in vitro and then prevented renal injury in diabetic rats via reversing cav-1 Tyr(14) phosphorylation that influenced TLR4 activation. Streptozotocin (STZ)-induced diabetic rats received vehicle or curcumin for twelve weeks and podocytes were treated with HG in the presence or absence of curcumin in vitro. To further evaluate the effect of cav-1 phosphorylation at Tyr(14) on HG-induced podocyte inflammation response and TLR4 activation, a recombinant plasmid GFP-Cav-1 Y14F with a mutated phosphorylation site of cav-1, was transfected into cultured podocytes. In vivo, curcumin improved histological abnormalities and fibrosis of a diabetic kidney, inhibited renal inflammatory gene expression and reduced cav-1 phosphorylation at Tyr(14) and the expression of TLR4. Pretreatment of podocytes with curcumin reduced HG-stimulated production of proinflammatory cytokines, TLR4 and the phosphorylation of cav-1. But immunohistochemistry in rat kidney showed that the elevation of TLR4 expression is more evident in the renal interstitum than in the glomerulus where podocytes are located, and the possibility that the anti-inflammatory effects of curcumin on other cells in the kidney may be mediated through the same molecular pathways as in podocytes. Our study suggests that curcumin treatment ameliorates DN via inhibition of inflammatory gene expression by reversing caveolin-1 Tyr(14) phosphorylation that influenced TLR4 activation.

[(3) H]-L685,458 binding sites are abundant in multiple peripheral organs in rats: implications for safety assessment of putative γ-secretase targeting drugs.

γ-Secretase is a multimeric enzyme complex that carries out proteolytic processing to a variety of cellular proteins. It is currently explored as a therapeutic target for Alzheimer's disease (AD) and cancer. Mechanism-based toxicity needs to be thoroughly evaluated for γ-secretase inhibitory and/or modulatory drugs. This study comparatively assessed putative γ-secretase catalytic sites in rat peripheral tissues relative to brain and explored an effort of its pharmacological inhibition on hair regeneration. Using [(3) H]-labelled L685,458, a potent γ-secretase inhibitor, as probe, we found more abundant presence of γ-secretase binding sites in the liver, gastrointestinal tract, hair follicle, pituitary gland, ovary and testis, as compared to the brain. Local application of L658,458 delayed vibrissal regrowth following whisker removal. These results suggest that γ-secretase may execute important biological functions in many peripheral systems, as in the brain. The development of γ-secretase inhibitors/modulators for AD and cancer therapy should include close monitoring of toxicological panels for hepatic, gastrointestinal, endocrinal and reproductive functions.

Influence of gonadotropin-releasing hormone agonist on the effect of chemotherapy upon ovarian cancer and the prevention of chemotherapy-induced ovarian damage: an experimental study with nu/nu athymic mice.

BACKGROUND AND OBJECTIVE: Gonadotropin-releasing hormone (GnRH) plays an important role in the regulation of ovarian function and ovarian cancer cell growth. In this study, we determined whether administration of the GnRH agonist (GnRHa), triporelin, prior to cisplatin treatment affects cisplatin and/or prevents cisplatin-induced ovarian damage. METHODS: nu/nu mice were injected with ovarian cancer OVCAR-3 cells intraperitoneally. After two weeks, the mice were treated with saline (control), cisplatin, GnRHa, or cisplatin plus GnRHa for four weeks. At the end of the experimental protocol, blood, tumor, ovary, and uterine tissues were resected for hematoxylin and eosin (H&E) staining, immunohistochemical analyses of Ki67, nuclear factor-κB (NF-κB), and caspase-3, transmission electron microscopy of apoptosis, or enzyme-linked immunosorbent assay (ELISA) analyses of anti-Mullerian hormone (AMH). RESULTS: Cisplatin treatment effectively inhibited tumor growth in mice treated with human ovarian cancer cells; however the treatment also induced considerable toxicity. Immunohistochemical analyses showed that Ki67 expression was reduced in cisplatin-treated mice compared to control (P<0.05), but there was no statistically significant differences between cisplatin-treated mice and cisplatin plus GnRHa-treated mice (P>0.05), while expressions of NF-κB and caspase-3 were reduced and induced, respectively, in cisplatin-treated mice and cisplatin plus GnRHa-treated mice. Apoptosis occurred in the GnRHa, cisplatin, and cisplatin plus GnRHa-treated mice, but not in control mice. Ovaries exposed to GnRHa in both GnRHa mice and cisplatin-treated mice (combination group) had significantly more primordial and growth follicles and serum levels of AMH than those in the control mice and cisplatin-treated mice (P<0.05). CONCLUSIONS: Administration of GnRHa to mice significantly decreased the extent of ovarian damage induced by cisplatin, but did not affect the anti-tumor activity of cisplatin.

Contrast-enhanced ultrasound study of primary hepatic angiosarcoma: a pitfall of non-enhancement.

OBJECTIVE: To investigate the contrast-enhanced ultrasound (CEUS) characteristics of primary hepatic angiosarcoma (PHA). METHODS: The sonographic findings and CEUS images of PHA in three patients were retrospectively analyzed. RESULTS: In our study, 3 cases of PHA (2 multiple nodules and 1 solitary mass) showed similar enhancement pattern on CEUS, characterized by remarkable central non-enhancement and peripheral irregular enhancement in the arterial and portal phase, and complete wash-out in the late phase. Furthermore, we unexpectedly found that abundant neoplastic tissues were present in the central area of non-enhancement on pathological evaluation. Based on literature review, we supposed that the unusual finding may be associated with the very low velocity of blood flow in the central region of tumors. CONCLUSION: CEUS could well depict PHA with some common features, which may provide valuable clues in diagnosis of this rare disease. And non-necrotic tumor tissue of PHA could also demonstrate non-enhancement on CEUS, which warrant further investigations.

[Impacts of salt stress on the growth and physiological characteristics of Rosa rugosa].

Taking 1-year-old cuttings of a wild type and three cultivars of Rosa rugosa as test materials, this paper studied their biomass, photosynthesis, osmotic adjustment substance contents, root activity, and ion contents under the stress of different concentration NaCl. Salt stress inhibited the growth of the cuttings, and root was more sensitive than shoot. Under salt stress, wild rose had significantly higher contents of free proline and soluble sugar than the cultivars, and the contents of free proline and soluble sugar in cultivar 'Ziyan' were higher than those in cultivars 'Zhongke 2' and 'Purple Branch'. Compared with rose cultivars, the wild rose under salt stress had smaller changes in its photosynthetic characteristics and root activity. It was suggested that wild rose had a higher resistance to salt stress than the cultivars, and cultivar 'Ziyan' had a higher resistance than 'Purple Branch' and 'Zhongke 2'. All the test indices could be used as the indicators of R. rugosa salt-tolerance.

[Diagnosis and treatment of primary hepatic angiosarcoma: a report of 7 cases with a literature review].

OBJECTIVE: To explore the clinical features, diagnosis, treatment and prognosis of primary hepatic angiosarcoma (PHA). METHODS: The clinical data of 7 PHA patients admitted to our hospital from December 2004 to December 2010 were retrospectively analyzed and the relevant literatures reviewed. RESULTS: Seven cases (5 males and 2 females) were diagnosed as PHA among 1027 (0.68%) patients with primary hepatic malignant tumors. Their mean age was 43.3 years old (range: 33 - 74). Four cases were of solitary lesion and three of multiple lesions. No specific clinical features were observed. The PHA lesions were easily misdiagnosed as benign or hepatic metastatic tumors. Contrast enhanced ultrasound (CEUS) showed the lesions with characteristic manifestations. And the positron emission tomography (PET-CT) could confirm the hepatic lesions as malignant tumors. The survival time for two untreated cases was 3 & 5 months, for two cases with liver transplantation (LTx) 3 & 8 months and for two cases treated with surgical resection & targeted therapy was 14 & 19 months respectively. One case was lost to follow-up at 6 months after hepatic resection. CONCLUSION: PHA is a clinically rare and highly malignant tumor with a rapid progression and a poor prognosis. Both CEUS and PET-CT are helpful for its differential and confirmative diagnosis. LTx should be considered as a contraindication for PHA. Hepatic resection has proven to be beneficial for PHA patients with solitary lesion. Surgical resection plus targeted medicines may improve their survival.

[A survival analysis of patients with early-stage hepatocellular carcinoma fulfilling Milan criteria and undergoing hepatectomy].

OBJECTIVE: To summarize the experience of hepatectomy in patients with hepatocellular carcinoma fulfilling the Milan criteria and analyze the clinicopathological factors for patient survival and tumor recurrence. METHODS: The clinicopathological data of 104 patients with early-stage hepatocellular carcinoma fulfilling the Milan criteria and underwent hepatectomy at Peking Union Medical College Hospital between April 2003 and June 2009 were retrospectively analyzed. RESULTS: The median follow-up was 24 months. There were 54 recurrent cases. The 1-, 3- and 5-year cumulative disease-free survival rate were 63.0%, 32.6% and 22.4% respectively. Neither univariate analysis nor multivariate analysis indicated any factor significantly correlated with recurrence (P>0.05). The cumulative overall survival rate at 1, 3 and 5 years were 88.8%, 68.1% and 68.1% respectively. Univariate analysis revealed that blood transfusion (P=0.000), involvement of hepatic capsule (P=0.000) and postoperative transarterial chemotherapy (P=0.049) were significantly correlated with survival. And multivariate analysis indicated that blood transfusion (P=0.001) and involvement of hepatic capsule (P=0.000) were independent prognostic factors for survival. CONCLUSION: For the patients with early-stage hepatocellular carcinoma and compensated liver function fulfilling the Milan criteria, hepatectomy serves as the preferred treatment strategy.

[Clinical experiences of surgical manipulations for hepatic masses in difficult sites].

OBJECTIVE: To summarize the surgical experiences, risks, complications, and managements for hepatic masses in difficult sites. METHODS: Totally 47 patients were divided into three groups based on the liver tumor sites: primary porta hepatis group, secondary porta hepatis group, and caudate lobe group. All patients underwent different portion of hepatectomy. RESULTS: The surgery duration was (289.6 +/- 62.2) ml-nutes, intra-operative blood loss was (602.3 +/- 256.4) ml, and intra-operative blood transfusion was (524.0 +/- 325.9) ml. Incidence of surgical complications in each group was 61.5%, 26.9%, and 25%, respectively. Serious complications observed were biliary leakage (27.7%), bleeding (6.4%), and post-operative liver failure (2.1%). Three perioperative deaths were reported: two patients died of bleeding, and one patient died from liver failure. CONCLUSIONS: Dissection of the liver and exposure of major blood vessels and biliary ducts are of critical importance in the surgeries for hepatic masses in difficult sites, and post-operative complications may be remarkably reduced through delicate manipulations of the small intra-hepatic vessels and biliary ducts during resection. A thorough pre-operative evaluation plays a key role in predicting the feasibility and risks of the surgery. Damage to the major blood vessels adjacent to the tumor, in addition to bleeding, may result in in-flow or outflow obstruction and cause necrosis of the corresponding hepatic lobe. Compared with damage to the primary portal area, vascular damage to the secondary porta is generally associated with higher fatality.

[Preoperative evaluation of liver function using 99mTc-diethyl iminodiacetic acid based on single photon emission computed tomography].

OBJECTIVE: To establish a three-dimentional liver function evaluation system using 99mTc-diethyl iminodiacetic acid (99mTc-EHIDA) scintigraphy based on single photon emission computed tomography (SPECT). METHODS: Totally 16 patients with liver lesions were divided into cirrhosis group and non-cirrhosis group. SPECT was performed 2 days before operation and 5 days after operation. Serum liver functions were examined on the same day of scintigraphy. SPECT images of areas of interest of heart and liver were aquired. Time of the peak of EHIDA density in liver (Tpeak), five-minutes heart liver index (HLI5), blood clearance index (HH15), receptor index (LHL15), and the predictive values were calculated. RESULTS: Tpeak was not significantly different between two groups, while HLI5, HH15, and LHL15 were significantly different (P = 0.033, P = 0.001, and P = 0.005). HLI, and LHL15 were significantly correlated with preoperative total protein and prealbumin levels (P = 0.003, P = 0.015, P = 0.022, P = 0.038) and post-operative prealbumin (P = 0.037, P = 0.042). The predictive values of HLI5 and LHL15 correlated well with postoperative HLI5 and LHL15 (r = 0.675, P = 0.016; r = 0.629, P = 0.028). CONCLUSION: The three-dimentional liver function evaluation system using 99mTc-EHIDA based on liver SPECT may facilitate the further studies of risks of liver surgery.

[Early recurrence after the resection of hepatocellular carcinoma].

OBJECTIVE: To observe the precise time of the recurrence after resection of hepatocellular carcinoma (HCC) and to further explore the risk factors associated with postoperative recurrence. METHODS: Totally 94 patients who had undergone resection of HCC were divided into three groups based on the time of recurrence, which was indicated by the digital subtraction angiography (DSA) examination: recurrence between 1 to 6 months, recurrence between 7 to 12 months, and tumor-free after 12 months. Patients with intra-hepatic recurrence were treated with transcatheter arterial chemoembolization and confirmed by CT scans after embolization, contrast-enhanced ultrasound, or magnetic resonance imaging. RESULTS: The recurrence rates of 6 months and 1 year were 30.9% and 36.2%, respectively. No statistically significant difference between 6-month and 1-year recurrence rates was observed. Nine (26.5%) patients with recurrence and five (8.3%) patients free of tumor had previously presented as multifocal HCC, which showed a statistical significance (P = 0.032). The diagnostic accuracy of DSA was 87.2%, which was eventually confirmed by the other investigations. CONCLUSIONS: Most recurrences occure within the first six months postoperatively and multifocal carcinogenesis is one of the risk factors associated with early recurrence after liver resection for advanced HCC. DSA is an important surveillance for early detection of intra-hepatic recurrence after surgery; meanwhile, it also provides information for early management to control the disease progression and for future active therapies.

[Significance of Golgi glycoprotein 73, a new tumor marker in diagnosis of hepatocellular carcinoma: a primary study].

OBJECTIVE: To evaluate the sensitivity and specificity of Golgi glycoprotein 73 (GP73) for the diagnosis of hepatitis B related hepatocellular carcinoma (HCC). METHODS: Western blotting was used to detect the serum GP73level in 25 patients being HBV carrier, 24 HCC patients, 12 patients with non-liver disease, and 99 healthy controls. Serum alpha-fetoprotein (AFP) was detected by electrochemiluminescence reaction. The levels of sensitivity and specificity of serum GP73 in diagnosing HCC were compared with those of AFP. The serum GP73 levels of some HCC patients during the perioperative period were compared. RESULTS: The serum GP73 level of the HCC patients, all HBV positive, was (40.36 +/- 64.43) relative units, significantly higher than those of the HBV carriers, non-liver patients, and healthy controls [(7.82 +/- 10.72), (4.48 +/- 5.70), and (2.59 +/- 5.12) relative units respectively, all P < 0.01]. There was no difference of GP73 levels between the healthy controls and the patients of non liver diseases (P = 0.2925). The sensitivity of GP73 for the diagnosis of HCC was 76.9%, significantly higher than that of AFP (48.6%). The specificity for the diagnosis of HCC of GP73 was 92.9%. Findings in a few HCC patients showed that the GP73 level remained not remarkably lowered within a week after surgical resection; but became lower 1.5-2 years after surgery. There was no raise of GP73 in the patients with non- malignant liver lesions. The GP73 levels of 4 of the 6 intra-hepatic cholangiocarcinoma patients were between those of the HCC patients and HBV carriers. CONCLUSION: Serum GP73 has higher sensitivity and specificity in diagnosis of hepatitis B-related HCC than AFP, and it can become a new effective HCC tumor marker.
