Circulating tumor cells undergoing EMT are poorly correlated with clinical stages or predictive of recurrence in hepatocellular carcinoma. Sci Rep 2019; 9:7084. [PMID: 31068623 PMCID: PMC6506548 DOI: 10.1038/s41598-019-43572-1] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Accepted: 04/28/2019] [Indexed: 12/12/2022] Open
Abstract
Experimental and clinical studies have highlighted that circulating tumor cell (CTC) with phenotypic hallmarks of epithelial-mesenchymal transition (EMT) plays a critical role in the metastatic and recurrence of solid malignancy. Here we retrospectively evaluated the presence of CTC and its EMT phenotypes in hepatocellular carcinoma (HCC) patients and investigated their clinical relevance. We optimized the CanpatrolTM CTC analysis system to enumerate CTC and classify EMT phenotypes in 113 HCC patients before curative treatment and 143 HCC patients after curative treatment. The relationships between CTC and clinical characteristics were statistically analyzed. None of total CTC or its EMT phenotypes in HCC patients was correlated with clinical characteristics, such as age, sex, HBsAg, Child-Pugh score, liver cirrhosis, AFP, number of tumors, tumor size, vascular invasion and BCLC stage. Neither the level of total CTC nor its EMT phenotypes in HCC patients before or after curative treatment were predictive of recurrence. Additionally, dynamic changes of CTC and its EMT phenotypes were not relevant to HCC recurrence after curative treatment in our study. Wefound CTC count and EMT classification were not correlated with clinical stages or predictive of HCC recurrence, but further large, multicenter studies are needed to confirm these results.

Abstract
Hepatocellular carcinoma (HCC) is a highly malignant disease with a poor prognosis and high mortality due to a low early diagnosis rate, resistance to systemic treatments and progression to late-stage liver disease. Owing to limitations in the detection of HCC and the lack of awareness of healthcare systems, fewer than 40% of HCC patients are eligible for surgery due to advanced stages of the disease at the time of diagnosis and the occurrence of multiple lesions in the cirrhotic or fibrotic liver. At present, the updated American Association for the Study of Liver Disease (AASLD) guidelines no longer recommend alpha-fetoprotein (AFP) testing as a part of diagnostic evaluation. Thus, it is imperative to establish a novel diagnostic strategy with high sensitivity and reliability to monitor risk factors to detect HCC at an early stage. In recent years, “liquid biopsy,” (including circulating tumor cells (CTCs) and circulating tumor DNA (ctDNA)), has emerged as a technique for the characterization of circulating cells, providing a strong basis for the individualized treatment of patients. As a noninvasive detection method, liquid biopsy is expected to play an important role in the early diagnosis, dynamic monitoring of cancer patients and drug screening. In this review, we will focus on the clinical applications, recent studies and future prospects of liquid biopsy, particularly focusing on HCC.

Abstract
BACKGROUND/AIMS Alpha-fetoprotein (AFP) mRNA-expressing cells are candidates for circulating tumor cells in hepatocellular carcinoma. We analyzed portal vein blood, peripheral blood, and peritoneal lavage samples to detect the presence of AFP mRNA-expressing cells, and explored their relationship with metastasis. METHODS We measured the AFP mRNA expression in 112 sets of portal vein and peripheral blood samples and 61 peritoneal lavage samples that had been obtained during surgery. We estimated the change in the positive ratio of patients with AFP mRNA, the associated background factors, and the rate of recurrence. RESULTS The change in AFP mRNA positivity in the peripheral blood specimens was remarkable, while that in the portal vein blood and peritoneal lavage samples was similar during hepatectomy. Tumor location was the only factor associated with AFP mRNA positivity. The rate of recurrence was higher in the patients who were positive for AFP mRNA than in those who were negative 9-24 months after hepatectomy. During this limited period, the recurrence rate in the AFP mRNA-positive cases was significantly higher than that in the AFP mRNA-negative cases (p = 0.0472). Postoperative AFP mRNA positivity was not related to very early recurrence (0-9 months) or multicentric liver carcinogenesis (>24 months). CONCLUSION AFP mRNA positivity in the peripheral blood was elevated after hepatectomy, and the elevation depended on the tumor location. AFP mRNA positivity might contribute to recurrence-free survival 9-24 months after hepatectomy.

Abstract
Hepatocellular carcinoma (HCC) is a highly malignant tumor characterized by rapid progression, poor prognosis, and frequent hematogenous metastasis. A minimally invasive diagnostic biomarker that can predict disease progression and treatment response would be of extraordinary benefit. Therefore, we have investigated whether the number of circulating tumor cells (CTCs) is correlated with disease progression and treatment response in HCC. Here we report that the number of CTCs, monitored by in vivo flow cytometry (IVFC), is strongly correlated with disease progression and treatment response in a highly metastatic orthotopic nude mouse model of green fluorescent protein (GFP)-labeled HCC. Sorafenib treatment reduces the number of CTCs significantly. The decreased number of CTCs is consistent with low lung metastasis. This study has demonstrated a considerable clinical value of CTCs as a biomarker in predicting disease progression and monitoring therapeutic efficacy in patients with HCC.

Abstract
BACKGROUND This study was designed to investigate the correlation between postoperative recurrence of hepatocellular carcinoma (HCC) and perioperative expression and dynamic changes in cancer stem cell (CSC) markers in tumors and peripheral blood. METHODS In HCC patients who underwent curative resection (n = 64) or liver transplantation (LT) (n = 17), mRNA levels for K19, EpCAM, and CD44 in peripheral blood and HCC tissues before and after operation were examined using real-time RT-PCR. Postoperative recurrence was analyzed in patients who underwent resection. Study participants were divided into high and low ratio groups, according to the ratio of postoperative to preoperative mRNA levels for each marker. RESULTS K19 and CD44 mRNA levels in HCC tissues were higher in patients with recurrence than those without recurrence (p < 0.05 for all). Preoperative peripheral levels of K19 and EpCAM mRNA were higher in LT patients than in resection patients, and they were also significantly higher in cirrhotic patients of Child-Pugh Class B or C than those of Child-Pugh Class A (p < 0.05 for all). A high ratio of K19 mRNA was associated with lower relapse-free rate. Additionally, a high ratio for both K19 and CD44 mRNA was an independent poor prognostic factor for relapse-free survival (hazard ratio = 3.382, p = 0.016). CONCLUSIONS Preoperative peripheral levels of K19 and EpCAM mRNA were influenced by background liver status and HCC. Additionally, the ratio of postoperative to preoperative mRNA levels for CSC markers, especially K19 and CD44, was shown to be important to predict HCC recurrence.

Abstract
Paul Ehrlich, a German scientist, discovered what is known as the mast cell in the late 1800's, which has proven to be an important player in the immune system of vertebrates. Mast cells are ubiquitous throughout the tissues of the human body and play numerous roles, both beneficial and destructive. We know they are important in our army of immunity warrior cells, which defend us against viruses, bacteria and parasitic invaders. They are also very well known for the havoc they wreak, causing uncomfortable symptoms due to their release of histamine and other mediators which cause the all too familiar itching, sneezing, urticaria and rhinorrhea of allergic responses. Mast cell activities are diverse and include painful inflammatory reactions in autoimmune conditions such as rheumatoid arthritis. In the gastrointestinal system, mast cells are implicated in diverse actions such as increased gastric acid secretion, polyp formation and uncomfortable conditions such as Irritable Bowel Syndrome. The role of immunology and mast cells in these areas is intriguing but less well understood than their role in allergic responses. Because mast cells have been implicated in both physiologic as well as pathogenic processes, they have been the subjects of avid study. Review of the current literature on mast cell biology reveals that there are many studies of their presence within the tumor microenvironment and evidence, which supports mast cell influence on tumor angiogenesis, tumor invasion, and immune suppression. The studies reviewed in this article concentrate largely on mast cells in human GI malignancies. This review also provides background information regarding mast cells, such as their origination, their location within the body, how they are activated and how they function as mediators.

Abstract
Liver cancer is the fifth most common cancer in men and the seventh in women. During the past 20 years, the incidence of HCC has tripled while the 5-year survival rate has remained below 12%. The presence of circulating tumor cells (CTC) reflects the aggressiveness nature of a tumor. Many attempts have been made to develop assays that reliably detect and enumerate the CTC during the development of the HCC. In this case, the challenges are (1) there are few markers specific to the HCC (tumor cells versus nontumor cells) and (2) they can be used to quantify the number of CTC in the bloodstream. Another technical challenge consists of finding few CTC mixed with million leukocytes and billion erythrocytes. CTC detection and identification can be used to estimate prognosis and may serve as an early marker to assess antitumor activity of treatment. CTC can also be used to predict progression-free survival and overall survival. CTC are an interesting source of biological information in order to understand dissemination, drug resistance, and treatment-induced cell death. Our aim is to review and analyze the different new methods existing to detect, enumerate, and characterize the CTC in the peripheral circulation of patients with HCC.

Abstract
OBJECTIVE To investigate whether circulating cancer stem cells (CSCs) of hepatocellular carcinoma (HCC) can predict its recurrence after hepatectomy. BACKGROUND HCC recurrence frequently occurs within the first year after hepatectomy, probably due to circulating tumor cells that have been shed from the primary tumor before hepatectomy. Because CSCs are more likely to initiate tumor growth than mature cancer cells, a high level of circulating CSCs may be a hint for HCC recurrence. METHODS Multicolor flow cytometry was used to detect the number of circulating CSCs (CD45CD90CD44) in the peripheral circulation of 82 HCC patients 1 day before hepatectomy. The patients were monitored by CT or MRI for recurrence every 3 months. RESULTS Forty-one (50%) patients had recurrence after a median follow-up period of 13.2 months (range, 1.3-57.1 months). Patients with recurrence had a higher median level of circulating CSCs than patients without recurrence (0.02% vs. 0.01%; P < 0.0001). Circulating CSCs > 0.01% predicted intrahepatic recurrence (relative risk 3.54; 95% CI, 1.41-8.88; P = 0.007) and extrahepatic recurrence (relative risk 10.15; 95% CI, 3-34.4; P = 0.0002). Patients with >0.01% circulating CSCs had a lower 2-year recurrence-free survival rate (22.7% vs. 64.2%; P < 0.0001) and overall survival rate (58.5% vs. 94.1%; P = 0.0005) than patients with ≤0.01% circulating CSCs. On multivariable analysis, circulating CSCs > 0.01%, tumor stage and tumor size were independent factors predicting recurrence-free survival. CONCLUSIONS Circulating CSCs predicted posthepatectomy HCC recurrence with high accuracy. They may be the target of eradication in the prevention of posthepatectomy HCC metastasis and recurrence.

Abstract
Liver transplantation is the best treatment of patients with unresectable early hepatocellular carcinoma, allowing disease-free survival rates of 60-80% at 5 years. Despite these good results, some 10% of recipients experience a posttransplant HCC recurrence, which leads to death in almost all patients. Recurrence is either due to the growth of occult metastases or to the engraftment of circulating tumor cells. It can be hypothesized that strategies to decrease the engraftment of circulating tumor cells could decrease the risk of recurrence and, in addition, extend access to transplantation to patients with more advanced HCC. These potential strategies can be schematized into five steps, including (1) selecting recipients with low baseline levels of circulating HCC cells, by adding biological markers (such as alpha fetoprotein or molecular signatures) to the accepted combination of morphological criteria; (2) decreasing the perioperative release of HCC cells, with careful perioperative handling of the tumors; (3) preventing the engraftment of circulating HCC cells by decreasing liver graft ischemia-reperfusion injury, which has been shown to promote cancer cell engraftment and growth; (4) using anticancer drugs, including mammalian target of rapamycin inhibitors and (5) tuning immunity toward HCC clearance.

Abstract
This work aimed to investigate the correlation of the expression of α-fetoprotein (AFP) and glypican-3 (GPC3) mRNAs in the peripheral blood with primary hepatocellular carcinoma (HCC) and HCC metastasis by using multiple fluorescence quantitative reverse transcriptase-polymerase chain reaction (FQ-RT-PCR). Peripheral blood samples from 100 patients with HCC were collected. The positive expression rates of AFP mRNA of HCC, hepatitis B, and cirrhosis patients were 56, 5, and 10%, respectively. AFP mRNA was not detected in healthy subjects, hepatic hemangioma, or hepatic metastasis patients' samples. Those of GPC3 mRNA of HCC patients were 76%. GPC3 mRNA was not detected in healthy subjects, hepatitis B, cirrhosis, hepatic hemangioma, or hepatic metastasis patients' samples. In HCC patients' samples, the combined positive rate of AFP and GPC3 mRNA expressions was 81%. The relative expression levels of GPC3 mRNA in the metastasis group and nonmetastasis group were 0.98±0.38 and 0.72±0.26, respectively, and showed significantly different (P=0.001). However, no significant difference was observed in the AFP mRNA expression levels (P=0.134). In conclusion, the sensitivity of HCC diagnosis can be improved by combined detection of AFP and GPC3 mRNA expressions. GPC3 mRNA is HCC-specific, and may indicate HCC metastasis.

Abstract
The dissemination of hepatocellular carcinoma (HCC) cells into the circulation plays a critical role in post-operative recurrence and metastasis. Early detection of metastatic tumor cells is critical to identify HCC patients at high risk of relapse. MAGE-3 and -4 genes were evaluated by reverse transcription polymerase chain reaction for the possibility of using them as new markers for early detection of metastases in 160 chronic HCV Egyptian patients, 115 of them were complicated with HCC. The expressions of MAGE-3 and MAGE-4 mRNA in peripheral blood of patients with metastatic HCC were 36 and 52%, respectively. While the expressions of MAGE-3 and MAGE-4 mRNA in peripheral blood of patients with localized HCC were 12.5 and 15%, respectively. Moreover, at least one type of mRNA was found in the peripheral blood of 68% of the metastatic HCC patients and in 20% of the localized HCC patients. While neither the controls nor the cirrhotic patients show expression of MAGE-4 mRNA in their peripheral blood. MAGE-3 and MAGE-4 may be a promising diagnostic tool for monitoring the prognosis of HCC patients and early detection of occult hematogenous metastasis of HCC.

Abstract
PURPOSE Detection of AFP mRNA in peripheral blood is considered a useful predictor of HCC recurrence after resection. However, its interpretation and clinical significance remains to be determined. This study was designed to evaluate the clinical significance of detecting AFP mRNA positive cells in peripheral blood. METHODS A total of 153 patients without macroscopic vascular invasion, who underwent liver resection, were prospectively enrolled in this study. The pattern of HCC recurrence was confirmed by image studies and divided into four types: (1) no recurrence (control group, n = 68); (2) intrahepatic single recurrence (SR group, n = 28); (3) intrahepatic multiple recurrences (MR group, n = 38); and (4) extrahepatic HCC recurrence (EX group, n = 19). RESULTS HCC recurrence was identified in 85 (55.6%) patients during a follow-up of 8.6 ± 6.7 (range, 0.7-36) months. Multivariate analysis identified preoperative AFP mRNA (HR = 2.54; P = 0.006) as an independent risk factor for HCC recurrence. Preoperative AFP mRNA expression was a significant predictor of HCC recurrence in the MR/EX group (P = 0.029) but not in the SR group (P = 0.467). CONCLUSIONS Detection of AFP mRNA expression in peripheral blood before surgery for HCC is a useful predictor of multiple or extrahepatic HCC recurrences.

Effects of pre-operative transcatheter arterial chemoembolization for resectable hepatocellular carcinoma: Implication of circulating cancer cells by detection of α-fetoprotein mRNA. Exp Ther Med 2010; 1:485-491.

Abstract
Transcatheter arterial chemoembolization (TACE) is useful for the treatment of multiple hepatocellular carcinomas (HCCs). Pre-operative TACE is used to reduce recurrence caused by peri- and post-operative spread of cancer cells; however, the efficacy is controversial. In this study, we evaluated the efficacy of pre-operative TACE for HCC and the implication of circulating cancer cells, retrospectively. We analyzed 495 patients with HCC who had undergone hepatectomy between 1980 and 2006, including 252 patients (50.9%) who received pre-operative TACE. The median follow-up period was 49.9 months. We compared the survival of TACE and non-TACE groups and also performed subgroup analysis. α-fetoprotein (AFP) mRNA was quantified to represent circulating cancer cells. Pre-operative TACE prolonged disease-free survival after hepatectomy in patients with HCCs greater than 5 cm (5-year disease-free survival of the pre-operative TACE and no-TACE groups was 37.3 vs. 14.8%, p<0.05). Patients with tumors showing 70% or greater necrosis had a significantly more favorable survival, and those with complete necrosis were all AFP mRNA-negative. The survival of the AFP mRNA-positive patients was worse than that of the AFP mRNA-negative patients. Pre-operative TACE may be beneficial for patients with tumors larger than 5 cm, and AFP mRNA quantification may be useful for the prediction of survival after surgery in TACE-treated patients.

Abstract
BACKGROUND Updated National Academy of Clinical Biochemistry Laboratory Medicine Practice Guidelines for the use of tumor markers in the clinic have been developed. METHODS Published reports relevant to use of tumor markers for 4 cancer sites--liver, bladder, cervical, and gastric--were critically reviewed. RESULTS Alpha-fetoprotein (AFP) may be used in conjunction with abdominal ultrasound for early detection of hepatocellular carcinoma (HCC) in patients with chronic hepatitis or cirrhosis associated with hepatitis B or C virus infection. AFP concentrations >200 microg/L in cirrhotic patients with typical hypervascular lesions >2 cm in size are consistent with HCC. After a diagnosis of HCC, posttreatment monitoring with AFP is recommended as an adjunct to imaging, especially in the absence of measurable disease. Although several urine markers have been proposed for bladder cancer, none at present can replace routine cystoscopy and cytology in the management of patients with this malignancy. Some may, however, be used as complementary adjuncts to direct more effective use of clinical procedures. Although carcinoembryonic antigen and CA 19-9 have been proposed for use gastric cancer and squamous cell carcinoma antigen for use in cervical cancer, none of these markers can currently be recommended for routine clinical use. CONCLUSIONS Implementation of these recommendations should encourage optimal use of tumor markers for patients with liver, bladder, cervical, or gastric cancers.

Abstract
BACKGROUND The aim of the study was to identify whether melanoma antigen (MAGE)-1 mRNA and alpha-fetoprotein (AFP) mRNA expressed in peripheral blood could be used to predict the recurrence and metastasis of hepatocellular carcinoma (HCC) after hepatectomy. METHODS One hundred and forty-two HCC patients underwent hepatectomy. The control group includes 27 patients with chronic virus hepatitis and cirrhosis and 10 healthy volunteers. Peripheral blood samples were collected on the seventh day before operation, seventh day after operation and 30th day after operation. MAGE-1 mRNA and AFP mRNA were tested by nested reverse transcription polymerase chain reaction. Median follow up was 25.5 months (range 4-40 months). Patient survival, disease-free survival and clinicopathological features were compared between patients with positive and negative MAGE-1 mRNA and/or AFP mRNA. RESULTS The expression of MAGE-1 mRNA and/or AFP mRNA in peripheral blood was closely correlated to the pathological stage and the positive ratio of tumour cells in the peripheral blood (P < 0.01). There was recurrence and/or metastasis after operation in 55 of 142 HCC patients. Among the 55 patients who had recurrence or metastasis, MAGE-1 mRNA and/or AFP mRNA in peripheral blood were persistently detected after operation in 38 patients and MAGE-1 mRNA and AFP mRNA turned to positive after operation in 14 patients. In contrast, no recurrence was found in 62 patients whose MAGE-1 mRNA and/or AFP mRNA turned to negative after operation. 88.1% (52 of 59) of patients with MAGE-1 mRNA and/or AFP mRNA persistently positive after operation showed recurrence or metastasis, whereas only 3.6% patients (3 of 83) with the negative of MAGE-1 mRNA and/or AFP mRNA after operation showed recurrence or metastasis (P < 0.001). CONCLUSION Melanoma antigen-1 mRNA combined with AFP mRNA in peripheral blood after hepatectomy is more sensitive and specific than AFP mRNA singly for predicting the recurrence and metastasis of the HCC patients, whereas preoperative transient detection is not.

Abstract
Hepatocellular carcinoma is the 5th most common cancer in the world. Prognosis for this disease is poor since hepatocellular carcinoma is mostly diagnosed at an advanced stage. Serum alpha-fetoprotein (AFP) is one of the most common diagnostic markers for hepatocellular carcinoma. However, its diagnostic value is more and more questioned. Therefore, research has focussed on AFP related parameters (AFP mRNA and AFP glycoforms). The aim of this paper is to review the present knowledge on AFP and its related parameters in diagnosing and monitoring HCC. AFP related parameters can be arranged in two types: AFP mRNA and AFP glycoforms. AFP mRNA is a potentially prognostic marker and AFP mRNA assays are based on PCR techniques. The AFP glycoforms have diagnostic potential and assays are based on isoelectric focussing and lectin affinity electrophoretic methods. Up to now the diagnostic use of the AFP related parameters is limited. Although some of them are recommended as a complementary test, they cannot (yet) replace serum AFP as the golden standard of diagnostic markers for hepatocellular carcinoma.

Abstract
Over the past quarter-century, liver transplantation (LT) has been established as a durable therapy for all forms of end-stage liver disease. LT appears ideally suited for hepatocellular carcinoma (HCC), as it involves complete oncologic resection and correction of the underlying liver dysfunction. Since LT based on the Milan criteria has been shown to provide good disease-free survival, LT is considered the optimal treatment for small HCC, especially in patients with underlying chronic liver disease. However, because there is a severe shortage of organ donors, not all patients in need can be offered LT. Transplant listing criteria must simultaneously determine the greatest number of suitable candidates for LT while rejecting the smallest number of those who could benefit from LT. The amended model for end-stage liver disease allocation policy has had a positive effect on liver transplant candidates with HCC, and their number has been increasing significantly over the past several years. To minimize dropout from the waiting list, the treatment of HCC with procedures such as chemoembolization, radiofrequency ablation, or ethanol injection in patients awaiting LT have become widespread. It is currently accepted that liver resection is the best option for the treatment of small HCC when liver function is well preserved, and that LT is preferred when liver function is severely impaired (Child-Pugh class B or C). However, the question arises as to what is the best option for Child-Pugh class A patients with early HCC eligible for both resection and LT, especially in Western countries. HCC is a major indication for living donor liver transplantation (LDLT), because the risk of dropout while waiting is negligible. Extension of the Milan criteria in the setting of LDLT may offer more patients a potentially curative treatment without reducing the donor pool of organs for patients on the waiting list with nonmalignant liver disease. However, imprudent expansion of the selection criteria may result in more patients with HCC being cured at the expense of a higher incidence of recurrence.

Abstract
BACKGROUND To establish a new experimental model of human hepatocellular carcinoma by orthotopic implantation of tumoral cells with its subsequent removal, to generate and modulate circulating tumoral cells. MATERIALS AND METHODS Three human hepatoma cell lines (HepG2, PLC/PRF, and Mahlavu) were orthotopically implanted under the Glisson's capsule of the left lateral lobe of the liver in a total of 56 non-obese diabetic/severe combined immunodeficiency mice. Tumor removal was performed 30 d after injection, and a laparotomy without tumor removal was done in control mice. Generation of circulating cells was monitored by flow cytometry using fluorescein isothiocyanate-conjugated anti-HLA antibody. RESULTS In 26 mice implanted with Mahlavu cells, 20 developed a unique tumor allowing a resection (77%), which was technically feasible in 80% of cases. The overall perioperative mortality was 30% (3/10) after resection; no mortality was observed in the control group. The circulating tumoral cells decreased dramatically after resection of the tumor as compared with control mice. CONCLUSION This new model is feasible and may be an interesting useful tool to study the hepatocellular carcinoma metastatic process and is consistent with the human clinical practice.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide. Cirrhosis caused by hepatitis B virus, hepatitis C virus or chronic alcohol intake is associated with major risk. Systematic screening for HCC of asymptomatic patients with cirrhosis is needed for earlier detection of small tumors requiring treatment (liver transplantation, surgical resection, percutaneous techniques). The recommended screening strategy among cirrhotic patients is based on regular liver ultrasonography associated with serum alpha-fetoprotein (AFP) assay. As the performance of AFP is not satisfactory, additional tumoral markers are proposed (des-gamma-carboxyprothrombin, glycosylated AFP-L3 fraction). Currently, diagnosis of HCC in cirrhotic patients includes non-invasive tests (imaging after contrast administration, AFP assay); diagnostic biopsy is performed when imaging is limited. After treatment, tumor recurrence is assessed by regular follow-up (AFP assay and imaging). Despite the lack of accurate markers, recent developments in genomic and proteomic approaches will allow the discovery of new biomarkers for primary tumors, as well as for recurrence. This review summarizes the current state of biomarkers for screening, diagnosis and follow-up of HCC, and highlights new perspectives in the field.

Abstract
BACKGROUND AND OBJECTIVES Clinicopathologic features of poorly differentiated hepatocellular carcinoma (HCC) have not been elucidated. The purpose of this study was to clarify the characteristics of poorly differentiated HCC in hepatectomized patients. METHODS From 1986 to 2001, 354 HCC patients underwent curative hepatectomy in our institution and were prospectively followed. Histological examinations revealed 43 well-differentiated HCC tumors, 273 moderately differentiated HCC tumors, and 38 poorly differentiated HCC tumors. Clinicopathologic factors and outcomes after hepatectomy were compared statistically. RESULTS Only serum alpha-fetoprotein level was significantly different in the poorly differentiated HCC group from that in the moderately differentiated HCC group preoperatively (P=0.0001). Although there were no significant differences between overall survival rates or between disease-free survival rates in the three groups, distant metastasis within 2 years after hepatectomy occurred more frequently in the poorly differentiated HCC group (21%) than in the well-differentiated HCC group (2%) (P=0.011) or moderately differentiated HCC group (8%) (P=0.018). Distant metastasis occurred in about 40% of patients in the poorly differentiated HCC group with tumor size greater than 3 cm. CONCLUSIONS Poorly differentiated HCC tumors larger than 3 cm are already of advanced stage representing distant metastasis in the early period after hepatectomy.

Abstract
BACKGROUND We have previously reported that tissue expression levels of transcript AA454543 in hepatocellular carcinoma (HCC) are significantly higher than those of normal livers, livers with cirrhosis, and livers with hepatitis. In addition, a higher level of transcript AA454543 in tumor tissues is associated with poor prognosis. We aim to examine whether quantitative measurement of preoperative plasma transcript AA454543 can provide similar prognostic information. PATIENTS AND METHODS Blood samples were obtained from 84 HCC patients before surgery. Real-time quantitative reverse transcription-polymerase chain reaction, using TaqMan system, was employed to measure plasma transcript AA454543 and alpha-fetoprotein (AFP) RNA levels. We assessed their prediction power in prognosis using univariate and multivariate analyses. RESULTS High plasma transcript AA454543 RNA levels were associated with poor overall survival (log-rank test, P < .01). Patients with different plasma AFP RNA levels revealed no difference in overall survival (log-rank test, P = .88). By multivariate Cox regression analysis, plasma transcript AA454543 RNA level (hazard ratio = 4.8, P < .01) and tumor stage (hazard ratio = 1.7, P < .01) were determined to be independent risk factors for the prediction of overall survival. CONCLUSION Preoperative plasma transcript AA454543 RNA level can provide prognostic information for HCC patients receiving curative partial hepatectomy.

Abstract
OBJECTIVE To determine whether detection of hepatocellular carcinoma (HCC) cells by real-time quantitative RT-PCR targeting of alpha-fetoprotein mRNA (AFP mRNA) before or after curative hepatectomy predicts HCC recurrence and patient survival. SUMMARY BACKGROUND DATA The presence of cancer cells in peripheral blood and/or bone marrow in patients with malignant disease has been reported to correlate with outcome. METHODS Between July 2000 and June 2005, 136 consecutive HCC patients underwent primary curative hepatectomy. Bone marrow aspirated preoperatively, and peripheral blood samples collected before and after operation were subjected to real-time quantitative RT-PCR analysis using AFP mRNA as a target molecule. Median follow-up was 23 months (range, 6-54 months). Patient survival (PS), disease-free survival (DFS), and clinicopathologic features were compared between patients with positive and negative AFP mRNA. RESULTS Twenty-four patients died (22 from HCC). HCC recurred in 66 patients (hepatic in 37 [56.1%]; hepatic and remote in 17 [25.8%], and remote alone in 12 [18.2%]). Bone marrow was positive for AFP mRNA in 38 patients (27.9%) and negative in 98 (72.1%). One- and 3-year PS was 96.6% and 91.4%, respectively, with negative AFP mRNA versus 86.2% and 55.5%, respectively, with positive AFP mRNA (P < 0.0001). One- and 3-year DFS were 73.2% and 44.8%, respectively, with negative AFP mRNA versus 54.5% and 25.8%, respectively, with positive AFP mRNA (P = 0.0399). Portal vascular invasion, tumor size, multiple tumors, and tumor differentiation correlated with inferior PS and DFS on univariate analysis. On multivariate analysis, positive AFP mRNA was the most important risk factor for PS (P = 0.001) and DFS (P = 0.0165). In addition, positive AFP mRNA in peripheral blood after operation tended to predict reduced DFS. CONCLUSION AFP mRNA in the bone marrow and systemic circulation during the perioperative period predicts patient survival and recurrence after curative hepatic resection for HCC.

AIM To explore the potential prognostic role of preoperative tumor grade and blood AFP mRNA in a cohort of patients with hepatocellular carcinoma (HCC) eligible for radical therapies according to a well-defined treatment algorithm not including nodule size and number as absolute selection criteria. METHODS Fifty patients with a diagnosis of HCC were prospectively enrolled in the study. Inclusion criteria were: (1) histological assessment of tumor grade by means of percutaneous biopsies; (2) determination of AFP mRNA status in the blood; (3) patient's eligibility for radical therapies. RESULTS At preoperative evaluation, 54% of the study group had a well-differentiated HCC, 42% had AFP mRNA in the blood, 40% had a tumor larger than 5 cm and 56% had more than one nodule. Surgery (resection or liver transplantation) was performed in 29 patients, while 21 had percutaneous ablation procedures. After a median follow-up of 28 mo, 12-, 24-, and 36-mo survival rates were 78%, 58%, and 51%, respectively. Surgical therapy, performance status and three tumor-related variables (AFP mRNA, HCC grade and gross vascular invasion) resulted as significant survival predictors at univariate analysis. Nodule size and number did not perform as significant prognosticators. Multivariate study selected only surgical therapy and a biologically early HCC profile (AFP mRNA negative and well-differentiated tumor without gross vascular invasion) as independent survival variables. CONCLUSION The preoperative determination of tumor grade and blood AFP mRNA status may potentially refine the prognostic evaluation of HCC patients and improve the selection process for radical therapies.

Abstract
PURPOSE Intra- and extrahepatic recurrence is common, even after curative resection for hepatocellular carcinoma (HCC), suggesting preoperative or intraoperative tumor cell dissemination. Reverse transcription - polymerase chain reaction (RT-PCR) for alpha-fetoprotein (AFP) is used to detect circulating liver cancer cells. We previously developed a quantitative method that allows estimation of the AFP mRNA level by real-time PCR. In the present study, we used this method to measure the AFP mRNA level before and after resection of HCC, then correlated the findings with various clinicopathological characteristics and prognosis. METHODS We prospectively examined peripheral blood samples from 38 patients with HCC, and bone marrow aspirate from 25 of these patients. As a control, we examined bone marrow from 20 patients with benign diseases. The follow-up period ranged from 32 to 66 months. Real-time RT-PCR was used to detect AFP mRNA levels in the samples. RESULTS AFP was expressed in 9 (23.7%) of the 38 peripheral blood samples. The detection of AFP mRNA was significantly correlated with extrahepatic metastasis after primary surgery, and a shorter disease-free survival time (P = 0.0245 each). Bone marrow samples were defined as positive if they expressed AFP mRNA at levels higher than the maximum expressed level in the controls, because only 1 (5%) of the 20 control bone marrow samples had low AFP mRNA expression. Using this cutoff level, 12 (48%) of the 25 patients with HCC had positivity for AFP mRNA. The results of bone marrow RT-PCR did not correlate with the clinocopathological characteristics of prognosis. CONCLUSIONS Using real-time PCR to measure the AFP mRNA level in blood, but not bone marrow, could be useful for predicting postoperative tumor recurrence.

Abstract
There is much debate about the way in which epithelial tumors metastasize. It has been proposed that the bone marrow (BM) acts as a tumor cell reservoir. We injected human hepatocellular carcinoma (HCC) cells (Mahlavu cell line) into the livers, circulation or BM of NOD/SCID mice and circulating tumor cells were quantified. When injected under the Glisson capsule, a primary tumor developed and continuously yielded circulating tumor cells. Liver tumor removal led to a very low level of Mahlavu cells both in blood and BM 30 days later. When Mahlavu cells (cultured or from BM of primary mice femurs) were intravenously injected into mice, the number of cells in the bloodstream (BS) steadily decreased, whereas the BM was not significantly colonized. When Mahlavu cells were directly injected into one femur, the controlateral femur was not colonized. Microscopic analysis and a sensitive PCR assay (<1 Mahlavu cell/nuclear cells) both failed to detect human tumor cells in other organs regardless of injection route. In conclusion, our model strongly supports the hypothesis that HCCs continuously release cells into the BS. However, in sharp contrast with the current hypothesis, the BM is not specifically colonized by tumor cells but could store them at a very low level.

Abstract
BACKGROUND Alpha-fetoprotein (AFP) messenger RNA (mRNA) may be a potential marker of the dissemination of hepatocellular carcinoma (HCC) cells into the circulation. The aim of this prospective pilot study was to assess the prognostic value of quantitative levels of AFP mRNA in patients undergoing ablative treatment for HCC. METHODS Peripheral blood samples were taken from seven patients before and after treatment for measurement of AFP mRNA levels by reverse-transcriptase polymerase chain reaction (RT-PCR). Patients were treated with percutaneous radiofrequency thermal ablation (n=3) or transarterial chemoembolization (n=4). The level of AFP mRNA in blood was serially determined, and the time course was related to the clinical course and disease outcome. The median duration of follow-up was 14 months (range, 9-16 months). RESULTS HCC recurred locally in four patients, and lung metastases developed in two of them. Patients were divided into three groups on the basis of the pre- and post-treatment AFP mRNA status. Group 1 included four patients with consistently high serum AFP and AFP mRNA levels (pre- and post-treatment). These patients developed distant and local recurrence. Group 2 included a patient with serum-negative AFP mRNA and normal AFP levels at entry. Although serum AFP remained within normal range, mean AFP mRNA increased from 10 to 95 copies/microg RNA. This patient had no distant metastases, but his tumor markedly increased in size. In Group 3, AFP mRNA and serum AFP remained within normal range before and after treatment. These two patients did not develop either local or distant metastases during the follow-up period. CONCLUSIONS Although this is a small sample size pilot study these findings imply that quantitative measurement of AFP-expressing cells in peripheral blood may serve as a marker of HCC recurrence.

Abstract
AIM: To investigate the expression of SSX-1 and NY-ESO-1 mRNA in hepatocellular carcinoma (HCC) and their clinical significances.
METHODS: The expression of SSX-1 and NY-ESO-1 mRNA were detected in the cancer tissues, the corresponding cancer-adjacent tissues and the peripheral blood of 26 patients with HCC as well as of 20 controls by reverse transcription polymerase chain reaction (RT-PCR). A randomized sample of the RT-PCR products was selected for DNA sequencingto examine the reliability of results.
RESULTS: The positive rates of SSX-1 and NY-ESO-1 mRNA expression were 61.5%(16/26) and 11.5% (3/26), respectively, in cancer tissues, and they were 46.2%(12/26) and 3.8%(1/26) in the peripheral blood. HCC patients, whose peripheral blood expressed SSX-1 or NY-ESO-1 mRNA, also expressed the same gene in their cancer tissues. SSX-1 and NY-ESO-1 mRNA were not expressed in cancer-adjacent tussues, and tissues and peripheral blood of the controls. DNA sequencing confirmed that the RT-PCR products were the target cDNA. No significant relationship was found between the expression of SSX-1 and NY-ESO-1 and the clinical indicators such as age, gender, tumor size, extent of differentiation, serum a-fetoprotein (AFP) level and infection of hepatitis B virus (P>0.05). However, in 37.5% patients with normal serum AFP (<20 ng/L), specific expression of SSX-1 mRNA was observed. The short-term recurrent rate was 50%(4/8) in patients whose peripheral blood expressed SSX-1 mRNA, while the rate in patients with no SSX-1 mRNA expression was 25%(3/12).
CONCLUSION: SSX-1 and NY-ESO-1 are expressed with a high specificity in HCC, and they can be used as the targets for specific immunotherapy of HCC. The combination of SSX-1 mRNA and AFP detection can help to improve the accuracy of diagnosis for HCC. The expression of SSX-1mRNA may be used as an indicator for reccurrence, metastesis and prognosis of HCC.

Abstract
AIM: To identify the role of alpha-fetoprotein (AFP) mRNA expression in peripheral blood one week after surgery as a predictor for recurrence of hepatocellular carcinoma (HCC).
METHODS: Published studies fulfilling the selection criteria were identified by searching several databases online. After a methodology assessment using a quality scale designed by European Lung Cancer Working Party, data in each research were aggregated by means of meta-analysis.
RESULTS: Altogether 368 cases were included in the 9 selected studies, which fulfilled the selection criteria. The quality scores ranged from 35% to 84% with a median score of 55%. The ‘design’ subscore had the lowest median value (38%). By aggregating the data, a high χ2 value (77.576) was presented. The fail-safe number was 136 and 64 for P = 0.05 and 0.01, respectively.
CONCLUSION: AFP mRNA expression in peripheral blood 1 wk after surgery correlated with the recurrence of HCC and was a good predictor for tumor recurrence.

Abstract
OBJECTIVE We sought to determine the outcome of living donor liver transplantation (LDLTx) in 316 adult patients with hepatocellular carcinoma (HCC). SUMMARY BACKGROUND DATA LDLTx has increasingly been performed worldwide, but the impact of the procedure on HCC has not been evaluated in a large series. METHODS Between October 1989 and December 2003, 1389 adults underwent LDLTx at 49 centers in Japan. In 316 (22.8%) who received LDLTx for HCC (70 females, 22%, median age 57 years; and 246 males, 88%, median age, 54 years), we analyzed pretransplant clinical status, imaging diagnosis, transplant procedure, pathologic study of explanted liver, and outcome. In 232 patients (73.4%), various surgical and nonsurgical therapies had been employed prior to LDLTx. The median follow-up period was 16 months (range, 2.5-72.0) RESULTS Currently, 236 (74.7%) of the patients are living. One- and 3-year patient survivals were 78.1% and 69.0%, respectively. Model end-stage liver disease score and preoperative serum alpha-fetoprotein level were independent risk factors for patient survival. Forty patients (12.7%) developed HCC recurrence. Alpha-fetoprotein level, tumor size, vascular invasion, and bilobar distribution were independent risk factors for HCC recurrence. Grade of histologic differentiation of HCC showed close correlation with tumor characteristics and recurrence. One- and 3-year recurrence-free survivals were 72.7% and 64.7%, respectively. When the Milan criteria were applied, patient survival and disease-free survival at 3 years were 78.7% and 79.1%, respectively, in patients who met the criteria, and 60.4% and 52.6%, respectively, in those who did not. CONCLUSION LDLTx can achieve acceptable survival in HCC patients, even when liver function is markedly impaired, or HCC is uncontrollable by conventional antitumor treatments.

Abstract
BACKGROUND Alpha-fetoprotein (AFP) messenger RNA (mRNA) in the blood reflects the presence of circulating hepatocellular carcinoma (HCC) cells and is a sensitive marker of HCC extrahepatic metastases. The specificity of this molecular marker and its correlation with the main HCC clinical-pathological parameters remains controversial, however. METHODS AFPmRNA was determined in 50 HCC patients and in 50 patients with diagnosis of cirrhosis (6), or colon (24) or, pancreatic (20) carcinoma. HCC patients with clinically evident extrahepatic metastasis were excluded. HCC diagnosis was confirmed in all patients by histology on percutaneous biopsies or surgical specimens; pathological grading was assessed at the same time. RESULTS AFPmRNA was positive in 20 HCC patients (40%) and in 18 patients without HCC (36%). The presence of AFPmRNA in the blood correlated significantly with cholestatic indices (p<0.01), nodule size (p=0.03), vascular invasion (p=0.006) and moderately or poorly differentiated HCC (p<0.0001). Moreover, survival analysis showed a significant impact of AFPmRNA detection on overall (p=0.04) and recurrence-free survival (p=0.0007) after a median follow-up of 17 months. CONCLUSIONS Although AFPmRNA is frequently detected in the blood, even in benign liver diseases or gastroenteric tumors, in HCC patients without clinical evidence of extrahepatic metastases it seemed to identify the biologically more aggressive tumors.

Abstract
OBJECTIVES Alpha-fetoprotein messenger RNA (AFP mRNA) in the peripheral blood (PB) of patients with hepatocellular carcinoma (HCC) has been considered to represent isolated tumor cells. We investigated its association with the prognosis after curative resection. METHODS Using a reverse-transcription polymerase chain reaction (RT-PCR)-based assay, AFP mRNA in the PB was determined prospectively in control and in 81 patients with curative resection for HCC. RESULTS Twenty-two (27.2%) and 19 (23.4%) of 81 HCC patients had AFP mRNA in their pre- and postoperative PB. Its presence preoperatively was not associated with an increased risk of HCC recurrence (54.5% vs 40.7%, p= 0.264). In contrast, the postoperative presence associated significantly with a higher incidence of recurrence (89.5% vs 30.6%, p < 0.001), irrespective of preoperative status. The odds ratio for HCC recurrence was 19.2 (95% confidence interval [CI]: 4.0- 91.7). The cmulative probability of recurrence-free survival was also much lower in patients with postoperatively positive AFP mRNA (p < 0.001). The Cox proportional hazards model also demonstrated a significant association with recurrence (p= 0.002). Preoperative serum AFP is also a significant factor and combination with postoperative AFP mRNA enhances the predictability, sensitivity (75.0%), specificity (93.3%), positive prediction (90.0%), and negative prediction (82.4%). CONCLUSIONS The postoperative detection of AFP mRNA in PB is associated with an increased risk of earlier HCC recurrence. Combination with preoperative serum AFP is useful in predictability.

Abstract
The theoretical possibility that exposure of a solid malignancy to high-intensity focused ultrasound (US), or HIFU, could lead to an increased rate of metastasis still remains. Using reverse transcriptase polymerase chain reaction (RT-PCR), the potential risk of hematogenous dissemination was assessed in HIFU-treated patients with solid malignancy. RT-PCR can demonstrate the presence or absence of specific RNA fragments. On the day before HIFU ablation, 5-mL peripheral blood samples were collected, and again 5 to 7 days after HIFU, from 26 enrolled patients (hepatocellular carcinoma, HCC: 10; osteosarcoma: 16). Total RNA was isolated and RT-PCR was performed to analyze the mRNA expression of (alpha-fetoprotein (AFP) and bone-specific alkaline phosphatase (BALP) genes. Positive AFP mRNA expression was preoperatively detected in 8 of 10 patients with HCC. In the postoperative specimens, positive expression was also detected in 8 of 10 patients. In 2 patients, circulating tumor cells were found preoperatively, but not postoperatively. Conversely, 2 patients with no circulating tumor cells preoperatively were found to have circulating tumor cells after HIFU. Of 16 osteosarcoma patients, 12 patients had circulating tumor cells and 4 had none. After HIFU treatment, 2 of the 12 patients had converted from presence to absence of circulating cells and the remaining 4 patients remained negative. It is concluded that patients undergoing complete HIFU ablation may demonstrate conversion from presence to absence of circulating tumor-specific marker mRNA, and that HIFU would not enhance the potential risk of metastasis in patients with malignant diseases.

Abstract
AIM: This study was to investigate whether surgery could increase cancer dissemination and postoperative recurrence in patients with hepatocellular carcinoma (HCC) by detection of human αfetoprotein messenger RNA (hAFP mRNA). hAFP mRNA in the peripheral blood of patients with HCC has been considered as a surrogate marker for circulating tumor cells.
METHODS: Eighty-one consecutive patients who underwent curative resection for HCC entered this prospective cohort study. We examined hAFP mRNA from the peripheral blood obtained preoperatively, perioperatively, and postoperatively to correlate the prognosis after curative resections from HCC patients and from the control subjects. Detection of hAFP mRNA by reverse transcriptase and polymerase chain reaction amplification (RT-PCR) was performed with primers specifically. The relations between the clinical variables (age, sex, associated liver cirrhosis, hepatitis B virus infection, hepatitis C virus infection, serum α-fetoprotein and Child-Pugh class), the histological variables (size, capsule, vascular permeation, grade of differentiation, and daughter nodules), hAFP mRNA in peripheral blood of 3 different sessions, and postoperative course (recurrence, and recurrence related death) were analysed.
RESULTS: No hAFP mRNA was detected in control group subjects. Twenty-two (27%), 24 (30%) and 19 (23%) of 81 HCC patients had hAFP mRNA positivity in the preoperative, perioperative and postoperative peripheral blood. The preoperative presence did not influence the risk of HCC recurrence (55% vs 41%, P = 0.280). In contrast, patients with postoperative presence had a significantly higher recurrence (90% vs 31%, P < 0.001; odds ratio 19.2; 95% confidence interval: 4.0-91.7). In the multivariate analysis by COX proportional hazards model, postoperative positivity had a significant influence on recurrence (P = 0.067) and recurrence related mortality (P = 0.017). Whereas, the perioperative positivity of hAFP mRNA did not increase HCC recurrence (58% vs.39%, P = 0.093). The correlation between perioperative hAFP mRNA positivity and recurrence related mortality had no statistical significance (P = 0.836).
CONCLUSION: From our study, perioperative detection of hAFP mRNA in peripheral blood of patients has no clinical relevance and significant role in the prediction of HCC recurrence. Surgical resection itself may not accelerate cancer dissemination and does not increase postoperative recurrence significantly either.

Abstract
Blood alpha-fetoprotein messenger RNA (AFP mRNA) is thought to be a marker of hepatocellular carcinoma (HCC). Its value as a predictor of HCC in patients at risk is not known. A series of 201 patients with compensated cirrhosis (114 men, mean age 58 years) underwent surveillance with semi-annual ultrasound and serum alpha-fetoprotein measurements. Total RNA was extracted from peripheral blood mononuclear cells collected at different intervals and AFP mRNA was retrotranscribed and amplified by nested polymerase chain reaction. Ten patients with HCC and 30 blood donors were used as controls. Three patients with HCC, 39 with cirrhosis under surveillance and four blood donors circulated AFP mRNA (30, 20 and 13%, NS). During 50 months of surveillance, 27 patients with cirrhosis developed HCC: the tumour was detected more often in patients with higher than normal baseline serum AFP (> or =7 IU/L) than in those with normal AFP levels (21%vs 9%, P = 0.02). The incidence of HCC was the same in patients with and without AFP mRNA at baseline (15%vs 14%). In 53 patients, AFP mRNA was re-tested after 6-25 months of surveillance. HCC developed in two of 11 (18%) who were initially AFP mRNA positive and later became negative, in none of those who were initially negative and later became positive and in two of 39 (5%) who remained persistently negative. In conclusion, blood AFP mRNA is not a sensitive predictor of HCC in patients with compensated cirrhosis.

Abstract
OBJECTIVE To determine whether the number of hepatocytes containing AFP mRNA shed into the bloodstream during transarterial chemoembolization (TAE) affects the incidence and pattern of recurrence of hepatocellular carcinoma (HCC). PATIENTS AND METHODS We developed a Taqman procedure to quantify AFP mRNA prospectively in 52 consecutive patients before and after TAE. Results are expressed in hepatocytes /mL. RESULTS Thirteen of the patients (24.5%) were positive for AFP mRNA (42 +/- 19 hepatocytes/mL) before TAE and 13 (24.5%) (80 +/- 32 hepatocytes/mL) after TAE; the difference was not significant. The presence of AFP mRNA in the bloodstream before TAE was associated with larger nodules (85.2 +/- 73.8 mm versus 34.8 +/- 26.1 mm; P = 0.006). Six of the patients were excluded from the analysis because they underwent curative surgery or were lost to follow-up. The circulating levels of AFP mRNA released in the 46 remaining patients after TAE did not affect metastasis-free survival. A significant number of extrahepatic metastases were found in patients exhibiting at least 1 AFP mRNA-positive blood sample either before or after TAE. However, the TAE procedure did not increase the risk of extrahepatic recurrences. CONCLUSION Cells containing AFP mRNA are inconsistently released into the circulation during TAE. The amount of these cells released does not affect the recurrence of HCC.

Abstract
The prognosis of patients with HCC still remains dismal. The life expectancy of HCC patients is hard to predict because of the high possibility of postoperative recurrence. Many factors, such as patient's general conditions, macroscopic tumor morphology, as well as tumor hitopathology features, have been proven of prognostic significance. Female HCC patient often has a better prognosis than male patient, which might be due to the receptor of sex hormones. Younger patients often have tumors with higher invasiveness and metastatic potentials, and their survival and prognosis are worse than the older ones. Co-existing hepatitis status and hepatic functional reserve have been confirmed as risk factors for recurrence. Serum alpha-fetoprotein (AFP) is useful not only for diagnosis, but also as a prognostic indicator for HCC patients. AFP mRNA has been proposed as a predictive marker of HCC cells disseminated into the circulation and for metastatic recurrence. Many pathologic features, such as tumor size, number, capsule state, cell differentiation, venous invasion, intrahepatic spreading, and advanced pTNM stage, are the best-established risk factors for recurrence and important aspects affecting the prognosis of patients with HCC. Marked inflammatory cell infiltration in the tumor could predict a better prognosis. Clinical stage is still the most important factor influencing on the prognosis. Extratumor spreading and lymph nodal metastasis are independent predictors for poor outcome. Some new predictive systems have recently been proposed. Different strategies of treatment might have significant different effects on the patients' prognosis. To date, surgical resection is still the only potentially curative treatment for HCC, including localized postoperative recurrences. Extent of resection, blood transfusion, occlusion of porta hepatis, and blood loss affect the survival and prognosis of HCC patients. Regional therapies provide alternative ways to improve the prognosis of HCC patients who have no opportunity to receive surgical treatment or postoperative recurrence. The combination of these treatment modalities is hopeful to further improve the prognosis. The efficacies of neoadjuvant (preoperative) or adjuvant (postoperative) chemotherapy or chemoembolization in preventing recurrence and on the HCC prognosis still remain great controversy, and deserves further evaluation. Biotherapy, including IFN-alpha therapy, will play more important role in preventing recurrence and metastasis of HCC after operation.

Abstract
alpha-fetoprotein (AFP) messenger RNA (mRNA) has been proposed as a marker of hepatocellular carcinoma (HCC) cells disseminated into the circulation, but its clinical significance remains controversial. We prospectively assessed the prognostic value of AFP mRNA in patients undergoing curative hepatic resection for HCC. Peripheral blood samples were taken from 87 patients before and after surgery to determine the presence of AFP mRNA by use of a reverse-transcription polymerase chain reaction. A primary endpoint was recurrence-free interval. AFP mRNA was detectable preoperatively in 31 patients (36%) and postoperatively in 30 patients (34%). With a median follow-up period of 28 months (range, 3-41 months), HCC recurred in 46 patients (53%). Among 4 groups separated according to preoperative and postoperative AFP mRNA status, patients with consistent positivity of AFP mRNA showed the highest recurrence rate (85%) and trend to distant or multiple recurrence. The recurrence-free interval was significantly shorter in patients with postoperative positivity of AFP mRNA than in those without (53% [95% CI, 36-71] vs. 88% [95% CI, 79-96] at 1 year, 37% [95% CI, 17-57] vs. 60% [95% CI, 46-75] at 2 years; P =.014), whereas the preoperative positivity of AFP mRNA provided no significance (P =.100). Cox's proportional-hazards model identified the postoperative positivity of AFP mRNA as an independent prognostic factor for HCC recurrence (relative risk, 2.33; 95% CI, 1.26-4.34; P =.007). In conclusion, postsurgical recurrence of HCC can be predicted by detecting AFP mRNA-expressing cells in peripheral blood.

Abstract
The members of MAGE gene family are highly expressed in human hepatocellular carcinoma (HCC). In the present study, we tested the tumour-specific MAGE-1 and MAGE-3 transcripts in the peripheral blood of HCC patients by nested RT-PCR to detect the circulating tumour cells and evaluate their potential clinical implication. Of 30 HCC patients, the positive rate of MAGE-1 and MAGE-3 transcripts was 43.3% (13 out of 30) and 33.3% (10 out of 30) in PBMC samples, whilst the positive rate was 70% (21 out of 30) and 53.3% (16 out of 30) in the resected HCC tissue samples, respectively. The positivity for at least one MAGE gene transcript was 63.3% (19 out of 30) in PBMC samples of HCC patients and 83.3% (25 out of 30) in the resected HCC tissue samples. MAGE-1 and/or MAGE-3 mRNA were not detected in the PBMC of those patients from whom the resected HCC tissues were MAGE-1 or MAGE-3 mRNA negative, nor in the 25 PBMC samples from healthy donors. The detection of MAGE transcripts in PBMC was correlated with the advanced stages and tumour size of the HCC, being 82.4% (14 out of 17) in tumour stages III and IVa, 56.6% (five out of nine) in stage II, and null (nought out of four) in stage I. The serum alpha-FP in 33.3% (10 out of 30) of HCC patients was normal or slightly elevated (< 40 ng ml(-1)). However, six of these 10 patients (alpha-FP < 40 ng ml(-1)) were MAGE-1 and /or MAGE-3 mRNA positive in their PBMC. The follow-up survey of MAGE mRNA in PBMC was performed in 12 patients. Seven patients with persistent MAGE-1 and/or MAGE-3 mRNA positive or from negative turned to positive died because of metastasis and/or recurrence. In striking contrast, all four patients with MAGE-1 and/or MAGE-3 mRNA from positive turned to negative and one patient with persistent MAGE-3 transcript negative are alive after last test. Collectively, detection of MAGE transcripts with follow-up survey in PBMC is a feasible and reliable assay for the early prediction of the relapse and prognosis of the HCC patients.

Abstract
BACKGROUND The significance of alpha-fetoprotein (AFP) messenger RNA as a surrogate marker for isolated tumor cells in the blood of patients with hepatocellular carcinoma (HCC) is controversial. Our goals were to correlate AFP mRNA with tumor recurrence and overall survival after patients with HCC received curative operations and to analyze AFP mRNA findings in control patients. METHODS In this prospective controlled study, RNA was purified from the blood of 85 patients with HCC before, during, and after therapy and from 116 control patients. Complementary DNA synthesis by reverse transcriptase and polymerase chain reaction amplification was performed with primers specifically for the AFP gene. Patients with HCC were divided into 4 subgroups depending on the therapy performed: (1) orthotopic liver transplantation (OLT), (2) resection, (3) transarterial chemoembolization, and (4) no therapy. RESULTS AFP mRNA was detected in 28% of the patients with HCC and 3% of the control patients (P <.01) before therapy. Of patients with HCC and OLT, 2 of the 6 patients who were AFP mRNA positive had a recurrence; none of the 4 patients who were negative had a recurrence. In the HCC patients who underwent tumor resection or received no therapy, the survival rates did not differ between patients who were AFP mRNA positive and negative (P =.21 and P =.94, respectively). After the tumor resection, no difference in survival at 2 years was evident in patients who were AFP mRNA positive versus those who were AFP mRNA negative. In the HCC patients who had curative operations (OLT and resection) the sensitivity and specificity of this test for tumor recurrence were 73% and 53%, respectively, excluding surgical mortality. The International Union Against Cancer tumor stages in the subgroups of OLT and resection showed no differences between patients with positive and negative findings (P =.76 and P =.15, respectively). AFP mRNA results and serum AFP levels revealed no correlation (P =.45). CONCLUSIONS The qualitative measurement of AFP mRNA in the blood of patients with HCC is not a clinically relevant method for determining therapy and prognosis, especially if AFP mRNA is detected during the surgical procedure or any other liver manipulation.

Abstract
We assessed whether circulating cell positivity using RT-PCR for carcinoembryonic antigen (CEA) cDNA was affected by venesection via a needle compared with a pre-aspirated venous cannula, and by increased PCR cycles. Systemic blood was sampled by needle and pre-aspirated cannula in 101 healthy individuals with no cancer history. After erythrocyte removal, samples were subjected to RT-PCR using specific primers for CEA, with 29 or 35 RT-PCR cycles. There was a significant difference between the number of subjects whose samples were negative when collected via needle venesection and positive when collected via pre-aspirated cannula, compared with positive by needle venesection and negative by pre-aspirated cannula for both 29 (P = 0.016) and 35 (P = 0.0111) RT-PCR cycles. Venesection technique (P = 0.01) and number of cycles (P = 0.003) were significant predictors of a positive result. Positive results in healthy subjects were reduced to less than 3% when an aspirated cannula was used for venesection and >29 PCR cycles were avoided.
