RESUMO
Objective:To investigate the epidemiological characteristics, diagnosis, treat-ment and prognosis of gallbladder cancer in China from 2010 to 2017.Methods:The single disease retrospective registration cohort study was conducted. Based on the concept of the real world study, the clinicopathological data, from multicenter retrospective clinical data database of gallbladder cancer of Chinese Research Group of Gallbladder Cancer (CRGGC), of 6 159 patients with gallbladder cancer who were admitted to 42 hospitals from January 2010 to December 2017 were collected. Observation indicators: (1) case resources; (2) age and sex distribution; (3) diagnosis; (4) surgical treatment and prognosis; (5) multimodality therapy and prognosis. The follow-up data of the 42 hospitals were collected and analyzed by the CRGGC. The main outcome indicator was the overall survival time from date of operation for surgical patients or date of diagnosis for non-surgical patients to the end of outcome event or the last follow-up. Measurement data with normal distribu-tion were represented as Mean±SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and com-parison between groups was conducted using the U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was performed using the Logistic forced regression model, and variables with P<0.1 in the univariate analysis were included for multivariate analysis. Multivariate analysis was performed using the Logistic stepwise regression model. The life table method was used to calculate survival rates and the Kaplan-Meier method was used to draw survival curves. Log-rank test was used for survival analysis. Results:(1) Case resources: of the 42 hospitals, there were 35 class A of tertiary hospitals and 7 class B of tertiary hospitals, 16 hospitals with high admission of gallbladder cancer and 26 hospitals with low admission of gallbladder cancer, respectively. Geographical distribution of the 42 hospitals: there were 9 hospitals in central China, 5 hospitals in northeast China, 22 hospitals in eastern China and 6 hospitals in western China. Geographical distribution of the 6 159 patients: there were 2 154 cases(34.973%) from central China, 705 cases(11.447%) from northeast China, 1 969 cases(31.969%) from eastern China and 1 331 cases(21.611%) from western China. The total average number of cases undergoing diagnosis and treatment in hospitals of the 6 159 patients was 18.3±4.5 per year, in which the average number of cases undergoing diagnosis and treatment in hospitals of 4 974 patients(80.760%) from hospitals with high admission of gallbladder cancer was 38.8±8.9 per year and the average number of cases undergoing diagnosis and treatment in hospitals of 1 185 patients(19.240%) from hospitals with low admission of gallbladder cancer was 5.7±1.9 per year. (2) Age and sex distribution: the age of 6 159 patients diagnosed as gallbladder cancer was 64(56,71) years, in which the age of 2 247 male patients(36.483%) diagnosed as gallbladder cancer was 64(58,71)years and the age of 3 912 female patients(63.517%) diagnosed as gallbladder cancer was 63(55,71)years. The sex ratio of female to male was 1.74:1. Of 6 159 patients, 3 886 cases(63.095%) were diagnosed as gallbladder cancer at 56 to 75 years old. There was a significant difference on age at diagnosis between male and female patients ( Z=-3.99, P<0.001). (3) Diagnosis: of 6 159 patients, 2 503 cases(40.640%) were initially diagnosed as gallbladder cancer and 3 656 cases(59.360%) were initially diagnosed as non-gallbladder cancer. There were 2 110 patients(34.259%) not undergoing surgical treatment, of which 200 cases(9.479%) were initially diagnosed as gallbladder cancer and 1 910 cases(90.521%) were initially diagnosed as non-gallbladder cancer. There were 4 049 patients(65.741%) undergoing surgical treatment, of which 2 303 cases(56.878%) were initially diagnosed as gallbladder cancer and 1 746 cases(43.122%) were initial diagnosed as non-gallbladder cancer. Of the 1 746 patients who were initially diagnosed as non-gallbladder cancer, there were 774 cases(19.116%) diagnosed as gallbladder cancer during operation and 972 cases(24.006%) diagnosed as gallbladder cancer after operation. Of 6 159 patients, there were 2 521 cases(40.932%), 2 335 cases(37.912%) and 1 114 cases(18.087%) undergoing ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) examination before initial diagnosis, respec-tively, and there were 3 259 cases(52.914%), 3 172 cases(51.502%) and 4 016 cases(65.205%) undergoing serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis, respectively. One patient may underwent multiple examinations. Results of univariate analysis showed that geographical distribution of hospitals (eastern China or western China), age ≥72 years, gallbladder cancer annual admission of hospitals, whether undergoing ultrasound, CT, MRI, serum carcinoembryonic antigen, CA19-9 or CA125 examination before initially diagnosis were related factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.45, 1.98, 0.69, 0.68, 2.43, 0.41, 1.63, 0.41, 0.39, 0.42, 95% confidence interval as 1.21-1.74, 1.64-2.40, 0.59-0.80, 0.60-0.78, 2.19-2.70, 0.37-0.45, 1.43-1.86, 0.37-0.45, 0.35-0.43, 0.38-0.47, P<0.05). Results of multivariate analysis showed that geographical distribution of hospitals (eastern China or western China), sex, age ≥72 years, gallbladder cancer annual admission of hospitals and cases undergoing ultrasound, CT, serum CA19-9 examination before initially diagnosis were indepen-dent influencing factors influencing initial diagnosis of gallbladder cancer patients ( odds ratio=1.36, 1.42, 0.89, 0.67, 1.85, 1.56, 1.57, 0.39, 95% confidence interval as 1.13-1.64, 1.16-1.73, 0.79-0.99, 0.57-0.78, 1.60-2.14, 1.38-1.77, 1.38-1.79, 0.35-0.43, P<0.05). (4) Surgical treatment and prognosis. Of the 4 049 patients undergoing surgical treatment, there were 2 447 cases(60.435%) with complete pathological staging data and follow-up data. Cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb were 85(3.474%), 201(8.214%), 71(2.902%), 890(36.371%), 382(15.611%), 33(1.348%) and 785(32.080%), respectively. The median follow-up time and median postoperative overall survival time of the 2 447 cases were 55.75 months (95% confidence interval as 52.78-58.35) and 23.46 months (95% confidence interval as 21.23-25.71), respectively. There was a significant difference in the overall survival between cases with pathological staging as stage 0, stage Ⅰ, stage Ⅱ, stage Ⅲa, stage Ⅲb, stage Ⅳa and stage Ⅳb ( χ2=512.47, P<0.001). Of the 4 049 patients undergoing surgical treatment, there were 2 988 cases(73.796%) with resectable tumor, 177 cases(4.371%) with unresectable tumor and 884 cases(21.833%) with tumor unassessable for resectabi-lity. Of the 2 988 cases with resectable tumor, there were 2 036 cases(68.139%) undergoing radical resection, 504 cases(16.867%) undergoing non-radical resection and 448 cases(14.994%) with operation unassessable for curative effect. Of the 2 447 cases with complete pathological staging data and follow-up data who underwent surgical treatment, there were 53 cases(2.166%) with unresectable tumor, 300 cases(12.260%) with resectable tumor and receiving non-radical resection, 1 441 cases(58.888%) with resectable tumor and receiving radical resection, 653 cases(26.686%) with resectable tumor and receiving operation unassessable for curative effect. There were 733 cases not undergoing surgical treatment with complete pathological staging data and follow-up data. There was a significant difference in the overall survival between cases not undergoing surgical treatment, cases undergoing surgical treatment for unresectable tumor, cases undergoing non-radical resection for resectable tumor and cases undergoing radical resection for resectable tumor ( χ2=121.04, P<0.001). (5) Multimodality therapy and prognosis: of 6 159 patients, there were 541 cases(8.784%) under-going postoperative adjuvant chemotherapy and advanced chemotherapy, 76 cases(1.234%) under-going radiotherapy. There were 1 170 advanced gallbladder cancer (pathological staging ≥stage Ⅲa) patients undergoing radical resection, including 126 cases(10.769%) with post-operative adjuvant chemotherapy and 1 044 cases(89.231%) without postoperative adjuvant chemo-therapy. There was no significant difference in the overall survival between cases with post-operative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.23, P=0.629). There were 658 patients with pathological staging as stage Ⅲa who underwent radical resection, including 66 cases(10.030%) with postoperative adjuvant chemotherapy and 592 cases(89.970%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemotherapy and cases without postoperative adjuvant chemotherapy ( χ2=0.05, P=0.817). There were 512 patients with pathological staging ≥stage Ⅲb who underwent radical resection, including 60 cases(11.719%) with postoperative adjuvant chemotherapy and 452 cases(88.281%) without postoperative adjuvant chemotherapy. There was no significant difference in the overall survival between cases with postoperative adjuvant chemo-therapy and cases without post-operative adjuvant chemo-therapy ( χ2=1.50, P=0.220). Conclusions:There are more women than men with gallbladder cancer in China and more than half of patients are diagnosed at the age of 56 to 75 years. Cases undergoing ultrasound, CT, serum CA19-9 examination before initial diagnosis are independent influencing factors influencing initial diagnosis of gallbladder cancer patients. Preoperative resectability evaluation can improve the therapy strategy and patient prognosis. Adjuvant chemotherapy for gallbladder cancer is not standardized and in low proportion in China.
RESUMO
Objective:To investigate the patients with hepatocellular carcinoma suitable for transcatheter arterial chemoembolization (TACE) after radical resection who were screened based on microvascular invasion (MVI) and Ki-67 expression.Methods:Of 400 patients with hepatocellular carcinoma who underwent radical resection in the Affiliated Hospital of Qingdao University from January 2013 to December 2019 were included and analyzed retrospectively, including 324 males and 76 females, aged (59.7±9.8) years, ranging from 32 to 87 years. According to whether they received adjuvant TACE treatment after operation, they were divided into simple operation group ( n=210) and TACE + operation group ( n=190). The recurrence in the first year after operation was followed up by outpatient reexamination. Univariate and multivariate Cox regression analysis were used to analyze the influencing factors of recurrence free survival after surgical resection. Subgroup analysis was performed according to Ki-67 and MVI to compare the recurrence free survival. Results:Multivariate Cox regression analysis showed that patients with proportion of Ki-67 positive cells ≥27.5% ( HR=2.073, 95% CI: 1.433-3.000, P<0.001) and MVI positive ( HR=2.339, 95% CI: 1.584-3.456, P<0.001) had increased risk of recurrence after radical resection. The 1-year cumulative recurrence free survival rate in the simple operation group was 70.0%, and there was no significant difference compared with 67.9% in the operation + TACE group( χ 2=0.08, P=0.774). Subgroup analysis: in the low expression of Ki-67 combined with negative MVI group ( n=128), the cumulative recurrence free survival rate of one year after operation in the simple operation group ( n=84) was 91.7%, which was significantly higher than 72.7% in the operation + TACE group ( n=44)( χ 2=8.22, P=0.004). There was no significant difference in the 1-year cumulative recurrence free survival rate between the simple operation group and the operation + TACE group (both P>0.05) in patients of Ki-67 high expression combined with MVI negative or Ki-67 low expression combined with MVI positive. In the Ki-67 high expression combined with MVI positive group ( n=107), the cumulative one-year recurrence free survival rate in the simple operation group ( n=62) was 40.3%, which was significantly lower than 60.0% in the operation + TACE group ( n=45)(χ 2=4.22, P=0.040). Conclusion:High expression of Ki-67 (≥27.5%) combined with positive MVI are the prediction factors for postoperative TACE treatment. Low expression Ki-67 (<27.5%) combined with negative MVI was contraindicated for postoperative TACE treatment.

Conclusion:Cases as male, case with posotive HBsAg, AST, GGT, TC, CEA and CA19-9 are independent risk factors for synCRLM in primary colorectal cancer, while lymphocytes, ALT and TG are independent protective factors for synCRLM in primary colorectal cancer.
RESUMO
Objective:To study combined adjuvant transcatheter arterial chemoembolization (TACE) with anti-tumor drug treatment on early hepatocellular carcinoma (HCC) recurrence in patients with microvascular invasion (MVI) after partial hepatectomy with curative intent.Methods:The clinical and pathological data of 169 patients with HCC who underwent partial hepatectomy with curative intent from January 2015 to December 2018 at the Affiliated Hospital of Qingdao University were retrospectively analyzed. MVI was diagnosed by postoperative histopathology. There were 147 males and 22 females, with the median age 56 years(ranged 32-79 years). The patients were divided into surgery group ( n=62, patients who did not receive adjuvant therapy), TACE group ( n=42, patients who only received TACE) and combined group ( n=65, patients who received TACE with anti-tumor drug) according to the therapies after resection. Patients in each group were further divided into grade M1 (mild) and grade M2 (severe) subgroups according to the severity of MVI. All patients were followed-up for observing tumor recurrence. The relapse-free survival in the three groups were compared using the Kaplan-Meier method and the log-rank test was used to compare the tumor-free survival rates. Results:The tumor-free survival rates of 169 patients at 1 and 2 years after operation were 59.2% and 40.8%. The tumor-free survival rates at 1 and 2 years after operation were 45.2% and 25.8% in surgery group, 61.9% and 40.5% in TACE group, 70.8% and 52.3% in combined group respectively. The differences among the three groups were significant: TACE group was better than surgery group, and combined group was better than TACE group, combined group was better than surgery group (all P<0.05). In TACE group and combined group, tumor-free survival rates of M1patients better than M2 patients, and the difference was significant ( P<0.05). Among M1 patients and M2 patients, tumor-free survival rates of combined group patients were better than surgery group and TACE group, the difference was significant (all P<0.05). The cumulative tumor-free survival rate was not significantly affected by different antineoplastic agents. Conclusion:Adjuvant TACE reduced the early recurrence rate of HCC patients with MVI. Adjuvant TACE combined with anti-tumor drug further reduced early tumor recurrence.
RESUMO
Objective:To explore the diagnosis and treatment of hepatocellular adenoma.Methods:The clinical data of 23 hepatocellular adenoma patients admitted to the Affiliated Hospital of Qingdao University from May 2013 to May 2020 were retrospectively analyzed.Results:Fifteen patients were female, the age ranged from 21 to 60. The maximum tumor diameter was from 2.5 cm to 15 cm.Most patients (15/23) were asymptomatic. There were 20 cases (87%) with single lesion and 3 cases (13%) with multiple lesions. Contrast-enhanced CT and MRI showed enhancement in the arterial phase, and de-enhancement in the portal phase as well as in the delayed phase. All cases underwent tumor resection. Hepatocellular adenoma was confirmed by pathology with partial canceration in one case and intratumoral hemorrhage in two cases. Sixteen cases were misdiagnosed preoperatively, 20 were followed up with the median follow-up time of 36 months. Recurrence was not found.Conclusion:Hepatocellular adenoma is uncommon and often misdiagnosed. Preoperative diagnosis is dependent on MRI.Given the fact of high rate misdiagnosis and a tendency of canceration,resection is recommended.
RESUMO
Objective To investigate the effect of docosahexaenoic acid (DHA) combined with cyclooxygenase-2 (COX-2) selective inhibitor NS-398 on the apoptosis of cholangiocarcinoma QBC939 cells and the mechanism.Methods In vitro,cholangiocarcinoma QBC939 cells were treated with 0,15,30,45,60 and 75 μg/ml DHA with 0,25,50,100,150 and 200 μmol/L NS-398,respectively.The absorbances of the QBC939 cells were measured by CCK8 and its growth inhibition ratios were analyzed.Flow cytometry was applied to detect cell apoptosis.The level of β-catenin and COX-2 mRNA and protein were measured by real-time PCR,immunocytochemistry and enzyme-linked immunoadsordent assay,respectively.Results DHA combined with NS-398 could significantly suppress the growth of QBC939 cells (P < 0.05).When the concentration of DHA went up to 45 μg/ml and NS-398 was 100 μmol/L,the relative growth inhibition rate of QBC939 cells was 90.0%.If the concentrations were increased,the result showed no significant differences.Furthermore,flow cytometry analysis indicated that DHA combined with NS-398 could induce QBC939 cells apoptosis at the early stage,and the apoptosis rate was significantly different between the experimental and control groups (P < 0.01).Real-time PCR showed low β-catenin and COX-2 expression in QBC939 cells disposed by DHA combined with NS-398,and their expression were significantly different between the experimental and control groups (P < 0.01).Immunocytochemistry and ELISA demonstrated that DHA combined with NS-398 could decrease β-catenin and COX-2 protein expression in QBC939 cells.Conclusion DHA combined with NS-398 induced apoptosis and inhibited proliferation of cholangiocarcinoma cells QBC939 in vitro through targeting β-catenin and COX-2.
RESUMO
Objective@#To clarify the clinicopathologic features of hepatocellular carcinoma (HCC) patients survived more than 10 years after radical hepatectomy.@*Methods@#Two hundreds and fifty-two patients who underwent curative resection for HCC between January 1999 and March 2006 at Department of Hepatopancreatobiliary Surgery, Affiliated Hospital of Qingdao University were included.There were 217 male cases and 35 female cases aging from 17 to 82 years with median age of (53.8±10.5)years. Followed by March 31 2016, clinicopathologic factors in 10-year survivors and patients who died within 10 years were compared by χ2 test, Kaplan-Meier survival analysis and Cox proportional hazards model and the prognostic factors affecting survival were identified.@*Results@#All patients were followed-up for 4.0 to 205.7 months with median time of 53.4 months. The 10-year overall survival rate was 26%, there were 62 cases(26.2%) who survived for more than 10 years after initial hepatectomy. In survival >10-year group, the paitents with ALT<40 U/L, gamma-glutamyl transpeptidase<64 U/L, albumin≥35 g/L, without liver cirrhosis and portal hypertension, Child-Pugh grade A, no blood transfusion, AFP≤20 μg/L, tumor size ≤5.0 cm, single tumor, high differentiation, TNM stage Ⅰ and TACE negative after resection were more than the patients in survival <10-year group (P<0.05). In multivariate analysis, Child-Pugh grade A, the tumor size ≤5.0 cm and TACE negative after resection were favorable independent factors associated with 10-year survival (P<0.05).@*Conclusion@#Based on the results of the study, Child-Pugh grade A, tumor size ≤5.0 cm and TACE negative after resection at initial hepatectomy might be biologically favorable conditions for patients surviving more than 10 years.
RESUMO
Background and purpose:Extranodal natural killer/T-cell lymphoma (ENKTL) is a form of non-Hodgkin’s lymphoma. The ENKTL incidence in China is much higher than that in the Western countries. The disease is highly malignant, not sensitive to chemotherapy, has short survival period and poor prognosis. Epstein-Barr virus (EBV) infection has close relationship with the development of the disease. However, there are still a few patients without EBV infection. This study aimed to discuss the clinical features and prognosis of EBV-encoded small RNA (EBER) in situ hybridization negative ENKTL.Methods:From Aug. 2011 to Oct. 2015, 326 cases were diagnosed with ENKTL from the First Affliated Hospital of Zhengzhou University. The expression of EBER was detected by in situ hy-bridization technique. The clinical pathological characteristics and prognosis of EBER-negative patients were analyzed. Results:In 326 patients with ENKTL, the negative rate of EBER was 2.45% (8/326). In 8 EBER-negative patients, the median survival time was 17 months. The log-rank test revealed that there was a signiifcant difference between EBER-negative and EBER-positive curves (χ2=6.407,P=0.011). Multivariate Cox proportional hazards regression analysis showed that in EBER-negative ENKTL, only lactate dehydrogenase (LDH) predicted survival time (P=0.008). EBV-DNA copy number in plasma was not signiifcantly correlated with survival time (P>0.05).Conclusion:The inci-dence of EBER-negative ENKTL is low. Patients with EBER-negative ENKTL have poorer prognosis than EBER-posi-tive patients. Elevated LDH may be a factor indicating poor prognosis.
RESUMO
Objective:To analyze clinical characteristics, treatment, and prognosis of B-cell lymphoma, unclassifiable, with features in-termediate between diffuse large B-cell lymphoma and Burkitt lymphoma (DLBCL/BL). Methods:The clinical and pathological data of 13 DLBCL/BL patients, who were treated in the First Affiliated Hospital of Zhengzhou University between January 2013 and December 2014, were collected. Overall survival (OS) and progression-free survival (PFS) were estimated by the Kaplan-Meier method. Through the log-rank test, survival curves were compared among groups classified by clinical stage, age, serum lactate dehydrogenase (LDH) lev-el, international prognostic index (IPI) score, or first chemotherapy regimen. Results:Among the 13 patients with DLBCL/BL, 12 pa-tients showed extra-nodal involvement. The median OS and PFS were only 10 and 6 months, respectively. Univariate analysis showed that the LDH levels and IPI scores exerted statistically significant effects on prognosis. Some borderline differences in survival were not-ed among the CHOP, CHOP-like, and intensive chemotherapy groups. Conclusion:DLBCL/BL is an aggressive B-cell lymphoma with a short survival time. The majority of patients presented extra-nodal involvement. DLBCL/BL did not respond well to CHOP or CHOP-like regimen, and more intensive chemotherapy may improve survival. Elevated LDH levels and high IPI scores were predictors of poor sur-vival.
RESUMO
Objective To study the clinical manifestations,endoscopic features,pathological features,treatment and prognosis of patients with duodenal neuroendocrine carcinoma (DNEC).Methods The clinical data of 9 patients with duodenal neuroendocrine carcinoma who were admitted to our hospital from December 2006 to December 2014 were retrospectively analyzed.Results There were 6 males and 3 females.The mean age was 61.5 years (range 48 ~75 years).The clinical manifestations were abdominal pain (n =7),jaundice (n =4),melena (n =1) and asymptomatic (n =1).The DNEC was usually solitary in the duodenum.The operations included duodenopancreatectomy (n =5),surgical resection (n =2),subtotal gastrectomy (n =1),and 1 patient was palliated by common bile duct stenting using an endoscopic retrograde cholangio-pancreatographic (ERCP) approach.The patients were followed up for 3 ~ 40 months after operation.For the 5 patients who underwent radical excision 4 were alive.One patient died from liver metastasis.For the 4 patients who underwent palliative therapy,one was alive,two died and one lost to follow-up.Conclusions The clinical manifestations of duodenal neuroendocrine carcinoma were non-specific.Endoscopic,pathologic and immumohisotochemical tests were important in the diagnosis.Surgical resection improved the prognosis of these patients.
RESUMO
Objective To analyze the factors that influence the survival condition during the first year after hepatectomy in patients with hepatocellular carcinoma (HCC). Methods Five hundred twentyeight HCC cases undergoing hepatectomy were included from January 1997 to December 2008.The factors and survival outcomes in these patients were analyzed. Results There were 302 patients dying during a medium follow-up of 35 months and 1-year cumulative survival was 85%.The causes of death during first year were tumor recurrence (78.1%,75/96) and liver dyscompensation ( 19.8%,19/96).By Cox regression analysis,tumor size ≥5 cm (P =0.047 ),vascular invasion ( P =0.018),histologic moderately and poorly differentiation ( P =0.001 ) and pathologically positive margin ( P =0.004 ) were significantly associated with tumor recurrence,and portal hypertension was an independent factor for patients dying from liver dysfunction ( P =0.001 ).Positive tumor margin was the most important factor associated with postoperative death within one year (59.3%,60/96). Conclusions During the first year after HCC resection,tumor recurrence and liver dysfunction are main factors influencing HCC patients' survival,nonR0 resection is the main factor causing tumor recurrence,and portal hypertension is an independent factor for patients dying of liver dyscompensation.
RESUMO
Objective To study the prognosis of patients with huge hepatocellular carcinoma (HCC) after R0 resection.Methods 517 patients with primary HCC who underwent R0 resection from January 1997 to December 2008 at the Affiliated Hospital of Medical College Qingdao University were analyzed retrospectively.Results The 5-and 10-years overall survivals (OS) in patients with huge HCC (≥10 cm; n=69) and in patients with HCC <10 cm (n=448) were 24%,18% and 49%,30%,respectively.The median OS was 23.0 and 58.0 month (P<0.001,log rank test) ; and the median disease-free survivals (DFS) were 15.3 and 34.8 month (P<0.001),respectively.The recurrence rate within the first year and the extrahepatic recurrence after resection in patients with huge HCC was significantly higher than in patients with HCC <10 cm (44.9% vs.24.3%,P=0.022;32.7% vs.16.0%,P=0.004).Independent poor prognostic factors of OS and DFS for patients with huge HCC after R0 resection were portal hypertension and vascular invasion.Preoperative transcatheter arterial chemoembolization (TACE) was an independent prognostic factor for better DFS.Conclusions Surgical resection for huge HCC is safe and feasible.For huge HCC after resection,portal hypertension and vascular invasion were poor prognostic factors.Preoperative TACE improved DFS after resection.
RESUMO
Objective To investigate the prognosis of patients with primary liver cancer in different pathological types after hepatectomy,and to analyze the effects of clinicopathological factors on the survival.Methods The clinical data of 567 patients with primary liver cancer who received hepatectomy at the Affiliated Hospital of Qingdao University from January 1997 to December 2008 were retrospectively analyzed.All patients were divided into hepatocellular carcinoma (HCC) group,cholangiocarcinoma (CC) group and combined hepatocellular carcinoma and cholangiocarcinoma (cHCC-CC) group.The survival and risk factors of the patients were analyzed.All data were analyzed by using the chi-square test,t test,analysis of variance.The survival curve was drawn by the Kaplan-Meier method and the survival of the 3 groups was compared by the Log-rank test.The risk factors were analyzed by the one-way analysis of variance and COX regression model.Results The results of pathological examination confirmed that 92.9% (527/567) patients were with HCC,4.6% (26/576) with CC and 2.5% (14/567)with cHCC-CC.The median cumulative survival time of patients with HCC was 48 months,which was significantly longer than 19 months of patients with CC and 14 months of patients with cHCC-CC (Log-rank value =4.354,8.847,P < 0.05).The median tumor-free survival time of patients with HCC was 26 months,which was significantly longer than 9 months of patients with CC and 9 months of patients with cHCC-CC (Log-rank value =6.479,7.708,P < 0.05).The tumor recurrence rate within 1 year of patients with HCC was 28.8% (152/527),which was significantly lower than 57.7% (15/26) of patients with CC or 9/14 of patients with cHCC-CC (F =17.046,P < 0.05).No vascular thrombosis was detected in patients with CC,but the regional lymph node metastasis rate was 19.2% (5/26),which was significantly higher than 2.8% (15/527) of patients with HCC (x2 =19.082,P < 0.05).Level of alpha-fetoprotein,TNM staging,tumor diameter,multiple foci,liver capsule invasion,satellite foci and lymph node metastasis were risk factors for the survivals of patients with primary liver cancer after hepateetomy (x2 =8.648,118.786,59.548,7.639,13.200,43.842,15.540,P < 0.05).Vascular tumor thrombosis and Child-Pugh classification were the risk factors for the survivals of patients with HCC or cHCC-CC (x2 =70.446,6.230,P < 0.05).TNM staging,tumor diameter,satellite foci and vascular tumor thrombusis were the independent risk factors for the survivals of patients with primary liver cancer (RR =1.420,1.050,1.513,1.899,P < 0.05) ; TNM staging,tumor diameter and vascular tumor thrombosis were the independent risk factors for the survivals of patients with HCC (RR =1.432,1.888,1.052,P < 0.05).TNM staging and tumor diameter were the independent risk factors for the survivals patients with CC (RR =1.473,1.503,P < 0.05).Conclusion Although CC and cHCC-CC take small proportion in the primary liver cancer,the tumor recurrence rate is higher and the survival rate is lower when compared with patients with HCC.
RESUMO
Objective To investigate the effects of ω-3 fatty acids (FA) on inflammatory reaction and immunologic function of patients after hepatectomy. Methods Totally 82 patients were randomized into control group and ω-3 FA group. Both groups received parenteral nutrition (PN) with equal nitrogen and calories. Patients in the control group received medium and long-chain lipid emulsion, and those in the ω-3 FA group received ω-3 FA combined with medium and long-chain lipid emulsion. Liver function test (serum total protein, prealbumin, albumin ,aspartate aminotransferase, alanine aminotransferase) , blood coagulation function (international normalized ratio) , immune globubin (IgA, IgG, and IgM) , CD3 and CD4/CD8 were measured on the first, third, and seventh post-operative day. Results Serum total protein in the ω-3 FA group [(61. 40 ±5. 12) g/L] was significantly higher than in the control group [(58. 54 ± 5. 53 ) g/L] (P = 0. 018 ) . Aspartate aminotransferase in the ω-3 FA group [(32. 37 ± 11. 92) U/L] was significantly lower than in the control group [(42. 50 ± 29. 97) U/L] (P = 0. 048). IgA in the ω-3 FA group [(2. 67 ± 1. 01) g/L] was significantly higher than in the control group [(2. 15 ±0.77) g/L] (P=0.027). IL-1β in the ω-3 FA group [(7.88 ±6.45) pg/ml] was significantly lower than in the control group [(12. 98 ± 11. 07) pg/ml] (P = 0.034). IL-2 in the ω-3 FA group [(24.98±20.38) pg/ml] was significantly lower than the control group [(43. 09 ± 20. 74) pg/ml] (P = 0.002). The white blood cell counts and coagulation function were not significantly different between two groups. Conclusion Total PN containing ω-3 FA can effectively improve immunologic function and liver function of patients after hepatectomy.
RESUMO
Objective To compare early enteral with parenteral nutrional support in patients after hepatectomy. Methods In this study, 59 patients were randomized into 2 groups to respectively receive enteral or parenteral nutritional support beginning the first day post-op for a week. The general nutrition condition, liver function, gut function, dosage of albumin, mortality, complication rate and expense were recorded. Results Patients were given same quantity of heat and nitrogen. At the end of the study, serum albumin, body weight and upper arm circumference had not reached the preoperative level in patients receiving enteral mutrition while all except for serum prealbumin had not reached the level in parenterally nutritional patients. Furthermore, the time of gut begins functional (29?12) h in enterally nutritional patients was shorter than in parenterally nutritional patients (38?14) h. Enteral nutrition was more economic than parenteral nutrition (P
