Thirty years ago, patients with PLC were often detected at relatively late stage, with a palpable mass or marked clinical symptoms and poor prognosis. In the past 30 years, the diagnosis and treatment of PLC have been greatly improved with better prognosis. METHODS: In order to study the changes of PLC during the 30 years, the clinical data of 3250 patients with PLC from 10 medical institutions of China were collected, ana- lyzed , and compared with those of 3254 PLC patients be- fore the 30 years. RESULTS: In the 3250 patients aged 1-80 years, with an average age of 49.1 years, the male to female ratio (2.3:1) was lower than that before the 30 years. 73.5% of the 3250 patients sought medical advice within 3 months after the onset of the disease in contrast to 63.8% before the 30 years. Compared with those patients before the 30 years the symptoms and signs were alleviated generally. The HBsAg positive rate was 81.0%, but the HCV-Ab positive rate was 13.2%. The AFP level in 75% of patients was elevated, but in the remaining 25% was normal. 1912 patients (58.8%) were confirmed pathologically. Among them 1755 patients (91.8%) had hepatocellular carcinoma. The overall resec- tion rate was 46.3%. Those who had early, middle, late stage carcinoma accounted for 29.9%, 51.5%, and 18.6%respectively in contrast to 0.4%, 47.0%, and 52.6% repor- ted before the 30 years. The 1-, 3-, 5-year survival rates of the patients were 66.1%, 39.7%, and 32.5% respectively, whereas 93.5%, 70.1%, and 59.1% for the early stage pa- tients, and 65.3%, 30.5%, and 23.5% for the middle stage patients. The half and 1-year survival rates of the late stage patients were 52.5%, and 14.7%, respectively. CONCLUSION: Comparison with the clinical data before and after the 30 years show that PLC can be diagnosed ear- ly. More PLC patients tend to undergo resection while re- ceiving a better conservative treatment, which ensures a prognosis.展开更多

A total of 222 patients with primary liver cancer who underwent hepatectomy were followed up from January 1986 to December 2010 at Chinese PLA General Hospital. The post-operative complication rate was 14.0% for all cases, 13.7% for hepatocellular carcinoma（HCC）, 10.0% for cholangiocarcinoma. The 1-, 3-, 5- and 10-year overall survival rates in patients with primary liver cancer after resection were 76.6%, 57.6%, 41.4%, and 21.0%. The survival rates were significantly higher in the HCC group than in the cholangiocarcinoma group（P=0.000）, in the non-anatomical resection group than in the anatomical resection group（P=0.005）, in the female group than in the male group（P=0.002）, in patients receiving no blood transfusion than in those who were given intra-operative blood transfusion（P=0.000）, in patients whose intra-operative blood loss was less than 400 m L than in those who intra-operatively lost more than 400 m L（P=0.000）. No significant difference was found in the survival rate between the HBs Ag-positive group and the HBs Ag-negative group（P=0.532）. Our study showed that anatomical resection, blood loss and blood transfusion were predictors of poor survival after hepatectomy for primary liver cancer patients, and concomitant hepatitis B virus infection bore no relation with the post-resection survival.展开更多

METHODS： From November 2001 to March 2003, 120 histologically verfied PLC patients without macroscopic tumor thrombi or macrosatellites or extrahepatic metastases underwent curative hepatectomy. Six hundreds and twenty-nine routine pathological sections from these patients were re-examined retrospectively by light microscopy. In the prospective study, curative hepatectomy was performed from November 2001 to March 2003 for 76 histologically verfied PLC patients without definite macroscopic tumor thrombi or macrosatellites or extrahepatic metastases in preoperative imaging. Six hundreds and forty-five pathological sections from these patients were examined by light microscopy. The resected liver specimens were minutely examined to measure the resection margin and to detect the number of daughter tumor nodules, dominant lesions, and macroscopic tumor thrombi inside the lumens of the major venous system. The paraffin sections were microscopically examined to detect the microsatellites, microscopic tumor thrombi, fibrosis tumor capsules, as well as capsule invasion and the distance of histological spread of the micrometastases. RESULTS： In the retrospective study, 70 micrometastases were found in surrounding liver in 26 of the 120 cases （21.7%）. The farthest distance of histological micrometastasis was 3.5 mm, 5.3 mm and 6.0 mm in 95%, 99% and 100% cases, respectively. Macroscopic tumor thrornbi or rnacrosatellites were observed in 18 of 76 cases, and 149 rnicrometastases were found in the surrounding live in 25 （43.1%） of 58 cases with no macroscopic tumor thrombi. The farthest distance of histological micrometastasis was 4.5 mm, 5.5 mm and 6.0 mm in 95%, 99% and 100% cases, respectively. Two hundred and sixty-seven rnicrometastases were found in surrounding liver in 14 （77.8%） out of 18 cases with macroscopic tumor thrombi or macrosatellites. The farthest distance of histological micrometastasis was 18.5 mm, 18.5 mm and 19.0 mm in 95%, 99% and 100% cases, respectively. CONCLUSION： The required minimal length of RM is 5.5 mm and 6 mm respectively to achieve 99% and 100% rnicrometastasis clearance in surrounding liver of PLC patients without macroscopic tumor thrornbi or rnacrosatellites, and should be greater than 18.5 mm to obtain 99% rnicrometastasis clearance in surrounding liver of patients with macroscopic tumor thrornbi or rnacrosatellites.展开更多

The purpose of this study was to evaluate these factors. METHODS: From March 2003 to May 2005, 228 consecutive patients with primary liver cancer underwent hepatectomy in our department were evaluated retrospectively to identify factors related to postoperative pleural effusion. RESULTS: Among the 228 patients, postoperative pleural effusions arose in 58 (25.4%). Univariate analysis showed significant differences in postoperative ascites, subphrenic collection, Pringle manoeuvre length, drainage amount on postoperative day 1, albumin level on postoperative day 7, alanine aminotransferase (ALT) level on postoperative days I and 3, prealbumin level on postoperative days 3 and 7, and tumor size (P<0.05). Ordinal regression analysis revealed that subphrenic collection, drainage on postoperative day I and ALT plus prealbumin on postoperative days I and 3 were statistically significantly related to postoperative pleural effusion (P<0.05). CONCLUSION: Subphrenic collection and operative injury to the liver appeared to be significantly related to pleural effusion after hepatectomy for primary liver cancer.展开更多

Met...Objective： To screen and analyze key express sequence tags （ESTs） which were differentially displayed in every period of SD rats＇ primary hepatic carcinoma and reveal the molecular mechanism of carcinogenesis. Methods： Using diethylnitrosamine （DENA） as a cancerigenic agent, animal models with different phases of primary hepatic cancer were constructed in SD rats. Rats were respectively sacrificed at d 14, d 28, d 56, d 77, d 105 and d 112 after the rats received DENA by gavage, then the livers were harvested. One part of the livers was classified according to their pathological changes, while the other was reserved for molecular mechanism studies on hepatocarcinogenesis. The differentially expressed genes were isolated from both normal and morbid tissues by mRNA differential display technique （DDRT-PCR）. After the fragments were sequenced, bioinformatics were .used to analyze the results. Results： Twelve differentially expressed cDNA fragments were obtained. Nine fragments had the homology with known cDNA clones, especially EST-7 was similar to BN/SsNHsdMCW mitochondrion gene and the identity was 100% which suggested EST-7 may be the part of BN/SsNHsdMCW mitochondrion gene. In contrast, other three fragments （EST-1, EST-3 and EST-5） had extremely low identity to any genes registered in GENBANK databases. Conclusions： BN/SsNHsdMCW mitochondrion gene was expressed in different periods of hepatocarcinogenesis. Moreover, EST-I, EST-3 and EST-5 were suggested to contribute to the development of rat hepatocarcinogenesis, and thus may be candidates of new targets of oncogenes or cancer suppressor genes.展开更多

The risk factors, prevention and management of postoperative pleural effusion in patients with primary liver cancer (PLC) who have undergone hepatectomy and the value of the argon beam coagulator (ABC) for the prevention of pleural effusion are studied. METHODS:A total of 523 patients with PLC at our institution who had had right hepatectomy from July 2000 to June 2004 were studied retrospectively. Comparative analysis was made to identify the factors contributing to postoperative pleural effusion and the efficacy of various managements. RESULTS:Of the 523 patients whose livers were dissociated using argon beam cutting and/or coagulation, 20(3.8%) developed pleural effusions;whereas in the other 467 patients underwent hepatectomy with suture ligation of the diaphragmatic secondary wound surface during the same period, 49(10.5%) had pleural effusion (P<0.01). The factors contributing to postoperative pleural effusion included subphrenic collection, postoperative hepatic insufficiency with ascites, duration of hepatic occlusion and underlying cirrhosis. CONCLUSIONS: Dissociation of the liver by argon beam cutting and/or coagulation can save suture ligation of the diaphragmatic secondary wound surface and may also prevent postoperative pleural effusion. Pleural drainage using an indwelling central-venous-catheter (CVC) in the pleural cavity is safe and efficacious.展开更多

A lot of patients with moderate and advanced liver tumor may lose the chance of opera- tion. The objective of present research was to study the ef- ficacy of transcatheter arterial chemoembolization (TACE) combined with percutaneous injection of chemical agents and acetic acids in the treatment of patients with primary liver cancer (PLC). METHODS: Thirty-three patients with middle and ad- vanced stage of PLC were divided into two groups: percu- taneous injection of chemical agents and acetic acids (15 patients, group A) and TACE (18 patients, group B). RESULTS: Tumor diameter and serum AFP level reduced to 86.6% and 83.3% in group A, and 55.5% and 40% in group B, respectively. There was significant difference be- tween the two groups ( P < 0 . 0 1 ) . The 1-, 2-, 3-, 4-year survival rates of group A were 96.7%, 86.6%, 51.3%, 33.3%, respectively and in group B were 66.7%, 44.4%, 16.7%, 0%, respectively (P<0.01). CONCLUSION: TACE combined with percutaneous injec- tion of chemical agents and acetic acids is efficacious to in- crease the survival rate of patients with PLC.展开更多

After the operation,the draining quantity from their abdominal cavities,and the days of transfusion and hospitalization wererecorded. The occurrence of complications and sur-vival time of the patient were followed up.Results: The postoperative mortality was 3.48% andthe occurrence rate of complications was 31.40%, whichwas significantly correlated with preoperative lowerlevel of serum albumin or the elevated γ-globulin lev-el and the amount of resected liver tissue. But their liverfunction before operation was fairly good, the 1-, 3-and 5-year survival rates after hepatectomy were58.2%, 35.7% and 17.64%.Conclusions: Patients with very big primary liver can-cer, should be subjected to hepatectomy if their liverfunction before operation are normal and the marginsare distinct between the tumor and liver tissues. Afterthe operation, other treatments are suitable for goodeffects.展开更多

文摘As a highly aggressive tumor,the pathophysiological mechanism of primary liver cancer has attracted much attention.In recent years,factors such as ferroptosis regulation,lipid peroxidation and metabolic abnormalities have emerged in the study of liver cancer,providing a new perspective for understanding the development of liver cancer.Ferroptosis regulation,lipid peroxidation and metabolic abnormalities play important roles in the occurrence and development of liver cancer.The regulation of ferroptosis is involved in apoptosis and necrosis,affecting cell survival and death.Lipid peroxidation promotes oxidative damage and promotes the invasion of liver cancer cells.Metabolic abnormalities,especially the disorders of glucose and lipid metabolism,directly affect the proliferation and growth of liver cancer cells.Studies of ferroptosis regulation and lipid peroxidation may help to discover new therapeutic targets and improve therapeutic outcomes.The understanding of metabolic abnormalities can provide new ideas for the prevention of liver cancer,and reduce the risk of disease by adjusting the metabolic process.This review focuses on the key roles of ferroptosis regulation,lipid peroxidation and metabolic abnormalities in this process.
文摘BACKGROUND The incidence and mortality rates of primary hepatocellular carcinoma(HCC)are high,and the conventional treatment is radiofrequency ablation(RFA)with transcatheter arterial chemoembolization(TACE);however,the 3-year survival rate is still low.Further,there are no visual methods to effectively predict their prognosis.AIM To explore the factors influencing the prognosis of HCC after RFA and TACE and develop a nomogram prediction model.METHODS Clinical and follow-up information of 150 patients with HCC treated using RFA and TACE in the Hangzhou Linping Hospital of Traditional Chinese Medicine from May 2020 to December 2022 was retrospectively collected and recorded.We examined their prognostic factors using multivariate logistic regression and created a nomogram prognosis prediction model using the R software(version 4.1.2).Internal verification was performed using the bootstrapping technique.The prognostic efficacy of the nomogram prediction model was evaluated using the concordance index(CI),calibration curve,and receiver operating characteristic RESULTS Of the 150 patients treated with RFA and TACE,92(61.33%)developed recurrence and metastasis.Logistic regression analysis identified six variables,and a predictive model was created.The internal validation results of the model showed a CI of 0.882.The correction curve trend of the prognosis prediction model was always near the diagonal,and the mean absolute error before and after internal validation was 0.021.The area under the curve of the prediction model after internal verification was 0.882[95%confidence interval(95%CI):0.820-0.945],with a specificity of 0.828 and sensitivity of 0.656.According to the Hosmer-Lemeshow test,χ^(2)=3.552 and P=0.895.The predictive model demonstrated a satisfactory calibration,and the decision curve analysis demonstrated its clinical applicability.CONCLUSION The prognosis of patients with HCC after RFA and TACE is affected by several factors.The developed prediction model based on the influencing parameters shows a good prognosis predictive efficacy.

文摘BACKGROUND Changes in alkaline phosphatase(ALP)andγ-glutamyltransferase(GGT)levels in patients with primary liver cancer(PLC)after radiofrequency ablation(RFA).Hepatocellular carcinoma is a malignant tumor with high incidence worldwide.As a common local treatment,RFA has attracted much attention for its efficacy and influence on liver function.AIM To investigate the effect of serum ALP and GGT levels on the prognosis of patients with PLC treated by RFA.METHODS The preoperative clinical data of 165 patients who were pathologically or clinically diagnosed with PLC and who received RFA in our hospital between October 2018 and June 2023 were collected.The chi-square test was used to compare the data between groups.The Kaplan-Meier method and Cox regression were used to analyze the associ-ations between serum ALP and GGT levels and overall survival,progression-free survival(PFS)and clinical characteristics of patients before treatment.RESULTS The 1-year survival rates of patients with normal(≤135 U/L)and abnormal(>135 U/L)serum ALP before treatment were 91%and 79%,respectively;the 2-year survival rates were 90%and 68%,respectively;and the 5-year survival rates were 35%and 18%,respectively.The difference between the two groups was statistically significant(P=0.01).Before treatment,the 1-year survival rates of patients with normal serum GGT levels(≤45 U/L)and abnormal serum GGT levels(>45 U/L)were 95%and 87%,the 2-year survival rates were 85%and 71%,and the 5-year survival rates were 37%and 21%,respectively.The difference between the two groups was statist-ically significant(P<0.001).Serum ALP[hazard ratio(HR)=1.766,95%confidence interval(95%CI):1.068-2.921,P=0.027]and GGT(HR=2.312,95%CI:1.367-3.912,P=0.002)is closely related to the overall survival of PLC patients after RF ablation and is an independent prognostic factor.The 1-year PFS rates were 72%and 50%,the 2-year PFS rates were 52%and 21%,and the 5-year PFS rates were 14%and 3%,respectively.The difference between the two groups was statistically significant(P<0001).The 1-year PFS rates were 81%and 56%in patients with normal and abnormal serum GGT levels before treatment,respectively;the 2-year PFS rates were 62%and 35%,respectively;and the 5-year PFS rates were 18%and 7%,respectively,with statistical significance between the two groups(P<0.001).The serum ALP concentration(HR=1.653,95%CI:1.001-2.729,P=0.049)and GGT(HR=1.949,95%CI:1.296-2.930,P=0.001)was closely associated with PFS after RFA in patients with PLC.The proportion of male patients with abnormal ALP levels is high,the Child-Pugh grade of liver function is poor,and the incidence of ascites is high.Among GGT-abnormal patients,the Child-Pugh grade of liver function was poor,the tumor stage was late,the proportion of patients with tumors≥5 cm was high,and the incidence of hepatic encephalopathy was high.CONCLUSION Serum ALP and GGT levels before treatment can be used to predict the prognosis of patients with PLC after RFA,and they have certain guiding significance for the long-term survival of patients with PLC after radiofrequency therapy.
文摘Objective:To explore the effect of transarterial chemoembolization(TACE)+CT-guided microwave ablation(MWA)on treating patients with primary liver cancer.Methods:78 primary liver cancer cases were enrolled and divided into groups according to their assigned surgical plans.The control group was treated with TACE alone,and the observation group was treated with TACE+CT-guided MWA.The efficacy of the treatment and the liver function indicators and follow-up results of the patients of the two groups were compared.Results:The efficacy of the treatment received by the observation group was higher than that of the control group.Besides,the patients in the observation group exhibited better improvement in liver function indicators after 3 months of treatment.Furthermore,the survival rates of 1 and 2 years after surgery of the observation group were all higher than those of the control group(P<0.05).Conclusion:TACE combined with CT-guided MWA is more effective in treating primary liver cancer compared to TACE alone.Besides,it resulted in better improvement of liver function and long-term survival rate.Therefore,this treatment regime should be popularized.

文摘Primary liver cancer is a severe and complex disease,leading to 800000 global deaths annually.Emerging evidence suggests that inflammation is one of the critical factors in the development of hepatocellular carcinoma(HCC).Patients with viral hepatitis,alcoholic hepatitis,and steatohepatitis symptoms are at higher risk of developing HCC.However,not all inflammatory factors have a pathogenic function in HCC development.The current study describes the process and mechanism of hepatitis development and its progression to HCC,particularly focusing on viral hepatitis,alcoholic hepatitis,and steatohepatitis.Furthermore,the roles of some essential inflammatory cytokines in HCC progression are described in addition to a summary of future research directions.
文摘BACKGROUND: Primary liver cancer (PLC) is one of the most frequently seen tumors in China. Thirty years ago, patients with PLC were often detected at relatively late stage, with a palpable mass or marked clinical symptoms and poor prognosis. In the past 30 years, the diagnosis and treatment of PLC have been greatly improved with better prognosis. METHODS: In order to study the changes of PLC during the 30 years, the clinical data of 3250 patients with PLC from 10 medical institutions of China were collected, ana- lyzed , and compared with those of 3254 PLC patients be- fore the 30 years. RESULTS: In the 3250 patients aged 1-80 years, with an average age of 49.1 years, the male to female ratio (2.3:1) was lower than that before the 30 years. 73.5% of the 3250 patients sought medical advice within 3 months after the onset of the disease in contrast to 63.8% before the 30 years. Compared with those patients before the 30 years the symptoms and signs were alleviated generally. The HBsAg positive rate was 81.0%, but the HCV-Ab positive rate was 13.2%. The AFP level in 75% of patients was elevated, but in the remaining 25% was normal. 1912 patients (58.8%) were confirmed pathologically. Among them 1755 patients (91.8%) had hepatocellular carcinoma. The overall resec- tion rate was 46.3%. Those who had early, middle, late stage carcinoma accounted for 29.9%, 51.5%, and 18.6%respectively in contrast to 0.4%, 47.0%, and 52.6% repor- ted before the 30 years. The 1-, 3-, 5-year survival rates of the patients were 66.1%, 39.7%, and 32.5% respectively, whereas 93.5%, 70.1%, and 59.1% for the early stage pa- tients, and 65.3%, 30.5%, and 23.5% for the middle stage patients. The half and 1-year survival rates of the late stage patients were 52.5%, and 14.7%, respectively. CONCLUSION: Comparison with the clinical data before and after the 30 years show that PLC can be diagnosed ear- ly. More PLC patients tend to undergo resection while re- ceiving a better conservative treatment, which ensures a prognosis.
文摘AIM: To explore recent trends, modes of diagnosis, ethnic distribution and the mortality to incidence ratio of primary liver cancer by subtypes in England and Wales.
文摘This study examined the impact of the operative and peri-operative factors on the long-term prognosis of patients with primary liver cancer undergoing hepatectomy. A total of 222 patients with primary liver cancer who underwent hepatectomy were followed up from January 1986 to December 2010 at Chinese PLA General Hospital. The post-operative complication rate was 14.0% for all cases, 13.7% for hepatocellular carcinoma（HCC）, 10.0% for cholangiocarcinoma. The 1-, 3-, 5- and 10-year overall survival rates in patients with primary liver cancer after resection were 76.6%, 57.6%, 41.4%, and 21.0%. The survival rates were significantly higher in the HCC group than in the cholangiocarcinoma group（P=0.000）, in the non-anatomical resection group than in the anatomical resection group（P=0.005）, in the female group than in the male group（P=0.002）, in patients receiving no blood transfusion than in those who were given intra-operative blood transfusion（P=0.000）, in patients whose intra-operative blood loss was less than 400 m L than in those who intra-operatively lost more than 400 m L（P=0.000）. No significant difference was found in the survival rate between the HBs Ag-positive group and the HBs Ag-negative group（P=0.532）. Our study showed that anatomical resection, blood loss and blood transfusion were predictors of poor survival after hepatectomy for primary liver cancer patients, and concomitant hepatitis B virus infection bore no relation with the post-resection survival.

文摘AIM： To describe the distribution of micrometastases in the surrounding liver of patients with primary liver cancer （PLC）, and to describe the minimal length of resection margin （RM） for hepatectomy. METHODS： From November 2001 to March 2003, 120 histologically verfied PLC patients without macroscopic tumor thrombi or macrosatellites or extrahepatic metastases underwent curative hepatectomy. Six hundreds and twenty-nine routine pathological sections from these patients were re-examined retrospectively by light microscopy. In the prospective study, curative hepatectomy was performed from November 2001 to March 2003 for 76 histologically verfied PLC patients without definite macroscopic tumor thrombi or macrosatellites or extrahepatic metastases in preoperative imaging. Six hundreds and forty-five pathological sections from these patients were examined by light microscopy. The resected liver specimens were minutely examined to measure the resection margin and to detect the number of daughter tumor nodules, dominant lesions, and macroscopic tumor thrombi inside the lumens of the major venous system. The paraffin sections were microscopically examined to detect the microsatellites, microscopic tumor thrombi, fibrosis tumor capsules, as well as capsule invasion and the distance of histological spread of the micrometastases. RESULTS： In the retrospective study, 70 micrometastases were found in surrounding liver in 26 of the 120 cases （21.7%）. The farthest distance of histological micrometastasis was 3.5 mm, 5.3 mm and 6.0 mm in 95%, 99% and 100% cases, respectively. Macroscopic tumor thrornbi or rnacrosatellites were observed in 18 of 76 cases, and 149 rnicrometastases were found in the surrounding live in 25 （43.1%） of 58 cases with no macroscopic tumor thrombi. The farthest distance of histological micrometastasis was 4.5 mm, 5.5 mm and 6.0 mm in 95%, 99% and 100% cases, respectively. Two hundred and sixty-seven rnicrometastases were found in surrounding liver in 14 （77.8%） out of 18 cases with macroscopic tumor thrombi or macrosatellites. The farthest distance of histological micrometastasis was 18.5 mm, 18.5 mm and 19.0 mm in 95%, 99% and 100% cases, respectively. CONCLUSION： The required minimal length of RM is 5.5 mm and 6 mm respectively to achieve 99% and 100% rnicrometastasis clearance in surrounding liver of PLC patients without macroscopic tumor thrornbi or rnacrosatellites, and should be greater than 18.5 mm to obtain 99% rnicrometastasis clearance in surrounding liver of patients with macroscopic tumor thrornbi or rnacrosatellites.
文摘BACKGROUND: Pleural effusion frequently complicates hepatectomy and multiple factors contribute to its development following hepatectomy for primary liver cancer. The purpose of this study was to evaluate these factors. METHODS: From March 2003 to May 2005, 228 consecutive patients with primary liver cancer underwent hepatectomy in our department were evaluated retrospectively to identify factors related to postoperative pleural effusion. RESULTS: Among the 228 patients, postoperative pleural effusions arose in 58 (25.4%). Univariate analysis showed significant differences in postoperative ascites, subphrenic collection, Pringle manoeuvre length, drainage amount on postoperative day 1, albumin level on postoperative day 7, alanine aminotransferase (ALT) level on postoperative days I and 3, prealbumin level on postoperative days 3 and 7, and tumor size (P<0.05). Ordinal regression analysis revealed that subphrenic collection, drainage on postoperative day I and ALT plus prealbumin on postoperative days I and 3 were statistically significantly related to postoperative pleural effusion (P<0.05). CONCLUSION: Subphrenic collection and operative injury to the liver appeared to be significantly related to pleural effusion after hepatectomy for primary liver cancer.

文摘Objective： To screen and analyze key express sequence tags （ESTs） which were differentially displayed in every period of SD rats＇ primary hepatic carcinoma and reveal the molecular mechanism of carcinogenesis. Methods： Using diethylnitrosamine （DENA） as a cancerigenic agent, animal models with different phases of primary hepatic cancer were constructed in SD rats. Rats were respectively sacrificed at d 14, d 28, d 56, d 77, d 105 and d 112 after the rats received DENA by gavage, then the livers were harvested. One part of the livers was classified according to their pathological changes, while the other was reserved for molecular mechanism studies on hepatocarcinogenesis. The differentially expressed genes were isolated from both normal and morbid tissues by mRNA differential display technique （DDRT-PCR）. After the fragments were sequenced, bioinformatics were .used to analyze the results. Results： Twelve differentially expressed cDNA fragments were obtained. Nine fragments had the homology with known cDNA clones, especially EST-7 was similar to BN/SsNHsdMCW mitochondrion gene and the identity was 100% which suggested EST-7 may be the part of BN/SsNHsdMCW mitochondrion gene. In contrast, other three fragments （EST-1, EST-3 and EST-5） had extremely low identity to any genes registered in GENBANK databases. Conclusions： BN/SsNHsdMCW mitochondrion gene was expressed in different periods of hepatocarcinogenesis. Moreover, EST-I, EST-3 and EST-5 were suggested to contribute to the development of rat hepatocarcinogenesis, and thus may be candidates of new targets of oncogenes or cancer suppressor genes.

文摘BACKGROUND In rare instances,primary liver cancer can be associated with intraocular metastasis(IOM).AIM To investigate the correlation between a diverse range of clinical characteristics and IOM in diabetic patients with primary liver cancer,and to determine potential risk factors in predicting IOM.METHODS We recruited a total of 722 diabetic patients with primary liver cancer.The differences between the IOM and non-intraocular metastasis(NIOM)groups in these patients were assessed using the chi-squared test and Student’s t-test.Binary logistic regression analysis was subsequently used to determine risk factors.Finally,the diagnostic value of IOM in this cohort with primary liver cancer was analyzed by receiver operating characteristic(ROC)curve analysis.RESULTS In all,13 patients had IOM.There were no remarkable intergroup differences with respect to age,sex,histopathological sub-types,or blood biochemical parameters.However,the IOM group had significantly higher alpha-fetoprotein(AFP)and cancer antigen 125(CA125)values than the NIOM group.Binary logistic regression identified AFP and CA125 to be significant risk factors for IOM in diabetic patients with primary liver cancer.ROC curve analysis showed that the area under the curve values for AFP and CA125 were 0.727 and 0.796,with the cut-off values of 994.20 ng/mL and 120.23 U/mL,respectively.The sensitivity and specicity for AFP were 92.3%and 59.9%,while those for CA125 were 84.6%and 70.1%,respectively.CONCLUSION Elevated AFP and CA125 represent significant risk factors for IOM in diabetic patients with primary liver cancer.
文摘Postoperative pleural effusion occurs frequently after hepatectomy. The risk factors, prevention and management of postoperative pleural effusion in patients with primary liver cancer (PLC) who have undergone hepatectomy and the value of the argon beam coagulator (ABC) for the prevention of pleural effusion are studied. METHODS:A total of 523 patients with PLC at our institution who had had right hepatectomy from July 2000 to June 2004 were studied retrospectively. Comparative analysis was made to identify the factors contributing to postoperative pleural effusion and the efficacy of various managements. RESULTS:Of the 523 patients whose livers were dissociated using argon beam cutting and/or coagulation, 20(3.8%) developed pleural effusions;whereas in the other 467 patients underwent hepatectomy with suture ligation of the diaphragmatic secondary wound surface during the same period, 49(10.5%) had pleural effusion (P<0.01). The factors contributing to postoperative pleural effusion included subphrenic collection, postoperative hepatic insufficiency with ascites, duration of hepatic occlusion and underlying cirrhosis. CONCLUSIONS: Dissociation of the liver by argon beam cutting and/or coagulation can save suture ligation of the diaphragmatic secondary wound surface and may also prevent postoperative pleural effusion. Pleural drainage using an indwelling central-venous-catheter (CVC) in the pleural cavity is safe and efficacious.

文摘BACKGROUND Alpha-fetoprotein(AFP)is one of the diagnostic standards for primary liver cancer(PLC);however,AFP exhibits insufficient sensitivity and specificity for diagnosing PLC.AIM To evaluate the effects of high-risk factors and the diagnostic value of AFP in stratified PLC.METHODS In total,289 PLC cases from 2013 to 2019 were selected for analysis.First,the contributions of high-risk factors in stratifying PLC were compared according to the following criteria:Child–Pugh score,clinical stage of liver cirrhosis,tumor size,and Barcelona Clinic Liver Cancer(BCLC)stage.Then,the diagnostic value of AFP was evaluated in different stratifications of PLC by receiver operating characteristic curves.For PLC cases in which AFP played little role,the diagnostic values of carcinoembryonic antigen(CEA),carbohydrate antigen 19-9(CA 19-9),gamma-glutamyl transferase(GGT),and AFP were analyzed.RESULTS The roles of high-risk factors differed in stratified PLC.The incidence of smoking and drinking history was higher in PLC with Child–Pugh scores of C(P<0.0167).The hepatitis B virus(HBV)infection rate in PLC with cirrhosis was more than in PLC without cirrhosis(P<0.0167).Small tumors were more prone to cirrhosis than large tumors(P<0.005).BCLC stage D PLC was more likely to be associated with HBV infection and cirrhosis(P<0.0083).AFP levels were higher in PLC with cirrhosis,diffuse tumors,and BCLC stage D disease.In diagnosing PLC defined as Child–Pugh A,B,and C,massive hepatoma,diffuse hepatoma,BCLC stage B,C,and D,and AFP showed significant diagnostic value[all area under the curve(AUC)>0.700].However,these measures were meaningless(AUC<0.600)in small hepatomas and BCLC A stage PLC,but could be replaced by the combined detection of CEA,CA 19-9,GGT,and AFP(AUC=0.810 and 0.846,respectively).CONCLUSION Stratification of PLC was essential for precise diagnoses and benefited from evaluating AFP levels.
文摘BACKGROUND: The resection rate of primary liver tumor in China is only about 20%. A lot of patients with moderate and advanced liver tumor may lose the chance of opera- tion. The objective of present research was to study the ef- ficacy of transcatheter arterial chemoembolization (TACE) combined with percutaneous injection of chemical agents and acetic acids in the treatment of patients with primary liver cancer (PLC). METHODS: Thirty-three patients with middle and ad- vanced stage of PLC were divided into two groups: percu- taneous injection of chemical agents and acetic acids (15 patients, group A) and TACE (18 patients, group B). RESULTS: Tumor diameter and serum AFP level reduced to 86.6% and 83.3% in group A, and 55.5% and 40% in group B, respectively. There was significant difference be- tween the two groups ( P < 0 . 0 1 ) . The 1-, 2-, 3-, 4-year survival rates of group A were 96.7%, 86.6%, 51.3%, 33.3%, respectively and in group B were 66.7%, 44.4%, 16.7%, 0%, respectively (P<0.01). CONCLUSION: TACE combined with percutaneous injec- tion of chemical agents and acetic acids is efficacious to in- crease the survival rate of patients with PLC.
文摘Objective: To study the indications for resection ofvery big primary liver cancer and the operative re-sults.Methods: From January 1985 to June 1996, 86 pa-tients with very big primary liver cancer (≥15cm indiameter) underwent hepatectomy in our hospital.The volume of bleeding and blood transfusion wasrecorded during the operation. After the operation,the draining quantity from their abdominal cavities,and the days of transfusion and hospitalization wererecorded. The occurrence of complications and sur-vival time of the patient were followed up.Results: The postoperative mortality was 3.48% andthe occurrence rate of complications was 31.40%, whichwas significantly correlated with preoperative lowerlevel of serum albumin or the elevated γ-globulin lev-el and the amount of resected liver tissue. But their liverfunction before operation was fairly good, the 1-, 3-and 5-year survival rates after hepatectomy were58.2%, 35.7% and 17.64%.Conclusions: Patients with very big primary liver can-cer, should be subjected to hepatectomy if their liverfunction before operation are normal and the marginsare distinct between the tumor and liver tissues. Afterthe operation, other treatments are suitable for goodeffects.

文摘BACKGROUND Primary liver cancer(PLC)is a major contributor to cancer-related deaths.Data on global and country-specific levels and trends of PLC are essential for understanding the effects of this disease and helping policymakers to allocate resources.AIM To investigate the association between the burden of PLC and socioeconomic development status.METHODS Cancer mortality and incidence rates were obtained from the Global Burden of Disease(GBD)2019,and the data were stratified by country and territory,sex,and the Socio-demographic Index(SDI)level.The association between the attributable etiology of PLC and socioeconomic development status,represented using the SDI,was described.The attributable etiology of PLC included hepatitis B,hepatitis C,alcohol use,and nonalcoholic steatohepatitis.The association between the attributable etiology of PLC and SDI was further stratified by sex and geographical location.A confidence analysis was also performed based on bootstrap draw.RESULTS The age-standardized incidence rate of PLC was 6.5[95%confidence intervals(CI):5.9-7.2]per 100000 person-years,which decreased by-27.5%(-37.0 to-16.6)from 1990 to 2019.Several countries located in East Asia,South Asia,West Africa,and North Africa shouldered the heaviest burden of PLC in 2019.In terms of incidence rates,the first leading underlying cause of PLC identified was hepatitis B,followed by hepatitis C,alcohol use,and nonalcoholic steatohepatitis.Regarding stratification using the SDI,the incidence rate of PLC was the highest for high and middle SDI locations.Further,the leading attributable etiologies of PLC were hepatitis B for the middle and high middle SDI locations while hepatitis C and nonalcoholic steatohepatitis for the high SDI locations.CONCLUSION The pronounced association between socioeconomic development status and PLC burden indicates socioeconomic development status affects attributable etiologies for PLC.GBD 2019 data are valuable for policymakers implementing PLC cost-effective interventions.
