RESUMO
Objective:To investigate the influencing factors for microvascular invasion (MVI) in hepatocellular carcinoma based on three-dimensional visualization and the construction of its nomogram model.Methods:The retrospective cohort study method was conducted. The clinico-pathological data of 190 patients with hepatocellular carcinoma who were admitted to Henan University People′s Hospital from May 2018 to May 2021 were collected. There were 148 males and 42 females, aged (58±12)years. The 190 patients were randomly divided into the training set of 133 cases and the validation set of 57 cases by the method of random number table in the ratio of 7:3. The abdominal three-dimensional visualization system was used to characterize the tumor morphology and other imaging features. Observation indicators: (1) analysis of influencing factors for MVI in hepatocellular carcinoma; (2) construction and evaluation of nomogram model of MVI in hepatocellular carcinoma. Measurement data with normal distribution were expressed as Mean± SD, and independent sample t test was used for comparison between groups. Measurement data with skewed distribution were expressed as M( Q1, Q3), and non-parametric rank sum test was used for comparison between groups. Count data were expressed as absolute numbers, and the chi-square test was used for comparison between groups. Corresponding statistical methods were used for univariate analysis. Binary Logistic regression model was used for multivariate analysis. Receiver operator characteristic (ROC) curves were plotted, and the nomogram model was assessed by area under the curve (AUC), calibration curve, and decision curve. Results:(1) Analysis of influencing factors for MVI in hepatocellular carcinoma. Among 190 patients with hepatocellular carcinoma, there were 97 cases of positive MVI (including 63 cases in the training set and 34 cases in the validation set) and 93 cases of negative MVI (including 70 cases in the training set and 23 cases in the validation set). Results of multivariate analysis showed that alpha-fetoprotein, vascular endothelial growth factor, tumor volume, the number of tumors, and tumor morphology were independent factors affecting the MVI of patients with hepatocellular carcinoma ( odds ratio=5.06, 3.62, 1.00, 2.02, 2.59, 95% confidence interval as 1.61-15.90, 1.28-10.20, 1.00-1.01, 1.02-3.98, 1.03-6.52, P<0.05). (2) Construction and evaluation of nomogram model of MVI in hepatocellular carcinoma. The results of multivariate analysis were incorporated to construct a nomogram prediction model for MVI of hepatocellular carcinoma. ROC curves showed that the AUC of the training set of nomogram model was 0.85 (95% confidence interval as 0.79-0.92), the optimal fractional cutoff based on the Jordon′s index was 0.51, the sensitivity was 0.71, and the specificity was 0.84. The above indicators of validation set were 0.92 (95% confidence interval as 0.85-0.99), 0.50, 0.90, and 0.82, respectively. The higher total score of the training set suggested a higher risk of MVI in hepatocellular carcinoma. The calibration curves of both training and validation sets of nomogram model fitted well with the standard curves and have a high degree of calibration. The decision curve showed a high net gain of nomogram model. Conclusions:Alpha-fetoprotein, vascular endothelial growth factor, tumor volume, the number of tumors, and tumor morphology are independent influencing factors for MVI in patients with hepatocellular carcinoma. A nomogram model constructed based on three-dimensional visualized imaging features can predict MVI in hepatocellular carcinoma.
RESUMO
Objective:To study the impact of the age-adjusted Charlson comorbidity index (ACCI) on the prognosis of patients with hilar cholangiocarcinoma following laparoscopic surgical resection.Methods:Clinical data of 136 patients with hilar cholangiocarcinoma undergoing laparoscopic surgery at Zhengzhou University People's Hospital between January 2013 and January 2018 were retrospectively analyzed, including 81 males and 55 females, aged (63.6±9.8) years. Patients were divided into two groups based on the median ACCI score of 4.0: the high ACCI group (ACCI>4.0, n=49) and low ACCI group (ACCI≤4.0, n=87). The prognosis was compared between the two group. Univariate and multivariate Cox regression analyses were performed to analyze the effect of ACCI on survival after laparoscopic surgery. Results:The 1- and 3-year cumulative survival rates in low ACCI group were 87.4% and 48.3%, respectively, compared to 53.1% and 4.1% in high ACCI group ( χ2=27.97, P<0.001). Univariate Cox regression analysis indicated that ACCI >4.0 was associated with prognosis ( HR=3.73, 95% CI: 2.44-5.68, P<0.001). Multivariate Cox regression analysis also indicated that ACCI >4.0 was associated with an increased risk of postoperative mortality in patients with hilar cholangiocarcinoma ( HR=2.69, 95% CI: 1.65-4.37, P<0.001). Conclusion:The ACCI is a significant risk factor for survival of patients with hilar cholangiocarcinoma following laparoscopic surgery, which could facilitate a precise preoperative assessment of patient status and choice of surgical approach.
RESUMO
Objective:To analyze the influencing factors of abnormal 15-minute retention rate of indocyanine green (ICG R15) (≥10%) in patients with hepatocellular carcinoma, and to construct a nomogram model, and to evaluate the prediction efficiency of the nomogram model.Methods:The clinical data of 190 patients with hepatocellular carcinoma in Zhengzhou University People's Hospital from December 2017 to June 2022 were retrospectively analyzed, including 148 males and 42 females, aged (57.8±9.9) years. According to ICG R15, the patients were divided into ICG R15 normal group ( n=134, ICG R15<10%) and ICG R15 abnormal group ( n=56, ICG R15≥10%). Univariate and multivariate logistic regression were used to analyze the influencing factors of abnormal ICG R15, and the nomogram model was established. The predictive ability of the model was evaluated by receiver operating characteristic (ROC) curve and C-index, and the model was verified by calibration curve and decision analysis curve. Results:Abnormal ICG R15 group the proportion of liver cirrhosis, albumin ≤35 g/L, hemoglobin ≤110 g/L, platelet count ≤100×10 9/L, prothrombin time >13 s, alanine aminotransferase >40 U/L, aspartate aminotransferase >40 U/L, total bilirubin >34.2 μmol/L, and the largest tumor diameter >5.0 cm, spleen volume >383.1 cm 3, spleen volume to of non-tumor liver volume (SNLR) >0.276 and liver tumor volume >117.2 cm 3 were higher than that of ICG R15 normal group, and the differences were statistically significant (all P<0.05). Logistic regression analysis showed that liver cirrhosis ( OR=3.89, 95% CI: 1.28-11.80, P=0.016), spleen volume >383.1 cm 3( OR=5.17, 95% CI: 1.38-19.38, P=0.015), SNLR >0.276 ( OR=5.54, 95% CI: 1.44-21.26, P=0.013) and total bilirubin >34.2 μmol/L( OR=10.20, 95% CI: 1.88-55.39, P=0.007) increased the risk of abnormal ICG R15. A nomogram model was constructed based on the above risk factors. The C-index of the model was 0.915 (95% CI: 0.872-0.957), and the area under the ROC curve predicted by the nomogram model was 0.915 (95% CI: 0.871-0.958). The calibration curve showed that the correlation index of the abnormal ICG R15 predicted by the nomogram was similar to actual situation. Decision analysis curve showed high returns. Conclusion:Liver cirrhosis, spleen volume >383.1 cm 3, SNLR>0.276 and total bilirubin >34.2 μmol/L were indepentlent risk factors for abnormal ICG R15 in patients with hepatocellur carcinoma. The clinical prediction model of ICG R15 abnormality constructed by nomogram has good prediction efficiency, which can provide a reference for evaluating preoperative liver reserve function of patients with hepatocellular carcinoma.
RESUMO
Background: This study introduces an alternative palliative surgical procedure called laparoscopic bridge choledochoduodenostomy (LBCDD) for patients with advanced malignant obstructive jaundice (AMOJ). Methods: Patients with AMOJ who had LBCDD between January 2017 and August 2021 were identified from databases of two institutions in China. Results: A total of 35 patients (male 12; female 23) with an average age of 64 years were enrolled. The average diameter of the tumor is 4.24â cm. All patients undertook LBCDD within an average operation time of 75â min with a mean blood loss of 32â ml. One patient had controlled bile leakage after the operation and two developed surgical site infection involving the epigastric orifices. All of them were solved by conservative treatment. All patients were discharged smoothly after an average hospital stay of 5.5 days, and no conversion to open surgery was required. Conclusions: LBCDD is a safe and efficient palliative surgery, which has a good therapeutic effect on patients with AMOJ.
RESUMO
Objective:To investigate the application value of peripheral blood circulating tumor cell (CTC) classification in the prediction of preoperative microvascular invasion of hepato-cellular carcinoma (HCC).Methods:The retrospective case-control study was conducted. The clinico-pathological data of 102 HCC patients who were admitted to Zhengzhou University People's Hospital from September 2018 to September 2020 were collected. There were 71 males and 31 females, aged from 29 to 80 years, with a median age of 57 years. Observation indicators: (1) surgical situations; (2) results of CTC detection and microvascular invasion in HCC patients; (3) results of CTC classification and the best cut-off value of CTC classification in the prediction of microvascular invasion in HCC; (4) influencing factors for microvascular invasion in HCC; (5) comparison of clinicopathological features in HCC patients with different cell counts in mesenchymal phenotype of CTC (M-CTC). Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent sample t test. Measurement data with skewed distribution were represented as M(range) or M( Q1, Q3), and comparison between groups was analyzed using the nonparametric rank sum U test. Count data were described as absolute numbers or percentages, and comparison between groups was analyzed using the chi-square test. The receiver operating characteristic (ROC) curve was used to determine the best cut-off value for the risk of microvascular invasion in patients. Univariate and multivariate analysis were performed using the Logistic regression model. Results:(1) Surgical situations. All 102 patients underwent surgery successfully, including 17 cases undergoing local hepatectomy, 43 cases under-going segmentectomy, 22 cases undergoing hepatic lobectomy, 13 cases undergoing hemilectomy and 7 cases undergoing enlarged hemilectomy. The operation time and the volume of intraoperative blood loss were 235(147,293)minutes and 300(110,500)mL of the 102 patients, respectively. (2) Results of CTC detection and microvascular invasion in HCC patients. Of 102 patients, there were 36 casas with epithelial phenotype of CTC (E-CTC), 86 cases with hybrid phenotype of CTC (H-CTC), 30 cases with M-CTC, respectively, and the total CTC (T-CTC) were positive in 89 cases. Results of postoperative pathological examination showed that there were 40 cases with micro-vascular inva-sion and 62 cases without microvascular invasion in the 102 patients. Of the 40 patients with micro-vascular invasion, the count of E-CTC, H-CTC, M-CTC and T-CTC were 0(0,1) per 5 mL, 4(2,5) per 5 mL, 1(0,2) per 5 mL and 5(3,8) per 5mL, respectively. The above indicators of the 62 cases without microvascular invasion were 0(0,1) per 5 mL, 3(1,5) per 5 mL, 0(0,0) per 5 mL and 3(2,6) per 5 mL, respectively. There were significant differences in the count of M-CTC and T-CTC between patients with and without microvascular invasion ( Z=-4.83, -2.96, P<0.05). (3) Results of CTC classi-fication and the best cut-off value of CTC classification in the prediction of microvascular invasion in HCC. The ROC curve showed that best cut-off value of M-CTC and T-CTC counts in the prediction of microvascular invasion in HCC were 1 per 5 mL and 4 per 5 mL, respectively, with the area under curve, the corresponding specificity, sensitivity were 0.70 (95% confidence interval as 0.60-0.81, P<0.05), 75.8%, 62.9% and 0.67 (95% confidence interval as 0.57-0.78, P<0.05), 60.0%, 72.5%, respec-tively. (4) Influencing factors for microvascular invasion in HCC. Result of univariate analysis showed that alpha fetoprotein (AFP), aspartate aminotransferase (AST), tumor diameter, tumor number, tumor margin, Barcelona clinic liver cancer staging, M-CTC counts and T-CTC counts were related factors influencing microvascular invasion in HCC ( odds ratio=3.13, 0.43, 4.92, 5.65, 2.54, 2.93, 8.25, 4.47, 95% confidence interval as 1.34-7.33, 0.19-0.98, 2.09-11.58, 2.35-13.63, 1.13-5.75, 1.27-6.74, 3.13-21.75, 1.88-10.61, P<0.05). Result of multivariate analysis showed that tumor diameter >5 cm, tumor number as multiple and M-CTC counts ≥1 per 5 mL were independent risk factors influencing microvascular invasion in HCC ( odds ratio=2.97, 4.14, 4.36, 95% c onfidence interval as 1.01-8.70, 1.14-15.02, 1.36-13.97, P<0.05). (5) Comparison of clinicopathological features in HCC patients with different cell counts in M-CTC. The 102 HCC patients were divided into the high M-CTC group of 30 cases with M-CTC counts ≥1 per 5 mL and the low M-CTC group of 72 cases with M-CTC counts <1 per 5 mL, according to the best cut-off value of M-CTC counts. Cases with hepatitis, cases with AFP >400 μg/L, cases with AST >35 U/L, cases with irregular tumor margin, cases with tumor diameter >5 cm, cases with tumor number as multiple and cases with micro-vascular invasion were 22, 17, 13, 21, 18, 16 and 22 in the high M-CTC group of 30 cases. The above indicators were 35, 18, 48, 26, 25, 21 and 18 in the low M-CTC group of 72 cases. There were significant differences in the above indicators between the high M-CTC group and the low M-CTC group ( χ2=5.25, 9.42, 4.80, 9.79, 5.55, 5.35, 20.75, P<0.05). Conclusions:The epithelial-mesen-chymal phenotype of peripheral blood CTC can be used to predict the preoperative microvascular invasion in HCC. Tumor diameter >5 cm, tumor number as multiple and M-CTC counts ≥1 per 5 mL are independent risk factors influencing microvascular invasion in HCC patients.
RESUMO
This study compared the clinicopathological characteristics and survival of patients with metastatic renal cell carcinoma (mRCC) stratified by age to identify clinical features and prognostic factors. Patients with renal cell carcinoma (RCC) between 2010 and 2015 were identified from the Surveillance, Epidemiology and End Results database. Age was an independent prognostic factor for patients with RCC, mRCC, mRCC of clear cell renal cell carcinoma and lung-related metastases. There were many significant differences between the younger and older groups, including differences in marital status, race, sex, year of diagnosis, histology grade, laterality, T stage, N stage, tumor size, type of treatment, including surgery, radiation or chemotherapy, and pattern of organic metastasis to the liver, lung, or brain (P<0.05). Moreover, different natural metastasis patterns and poorer overall survival were observed in the older group compared with the younger group (P<0.05). Parameters, including marital status, sex, year of diagnosis, histological grade, N stage, surgery, chemotherapy, lung metastasis and liver metastasis, were independent prognostic factors for elderly patients (P<0.05). Age plays a significant role in mRCC, and elderly patients with mRCC are a special group of individuals whose clinical characteristics and prognostic factors are different from those of younger patients; therefore, these patients require special attention.

The aim of this study was to evaluate the clinical features and prognostic factors of elderly patients with metastatic pancreatic cancer. Patients diagnosed with metastatic pancreatic cancer between 2004 and 2014 were identified from the Surveillance Epidemiology and End Results database. Clinical characteristics and prognostic factors in elderly patients with metastatic pancreatic cancer were examined. A total of 10784 metastatic pancreatic cancer patients between 65 and 80 years old were included and divided into three age groups. Elderly metastatic pancreatic cancer patients differed from younger patients in many aspects, including marital status, race, sex, T stage, N stage, treatment regimen, prognosis, cause of death, and metastatic characteristics (P<0.001). An analysis of prognostic factors showed that chemotherapy, as the main treatment for elderly patients, can significantly improve prognosis, while surgery can improve the prognosis of patients between 65 and 80 years old. Other factors, including sex, marital status, T stage, and site of metastasis, had different effects on patients in different age groups. Elderly patients with metastatic pancreatic cancer are a special group of individuals whose clinical characteristics and prognostic factors are different from those of younger patients, and these patients require special treatment and attention.

Objective:This study aimed to compare the clinical outcomes of laparoscopic pancreaticoduodenectomy (LPD) versus open pancreaticoduodenectomy (OPD).Methods:The clinical data of 386 patients who successfully underwent pancreaticoduodenectomy at the People's Hospital of Zhengzhou University from June 2017 to December 2019 were retrospectively analyzed. According to the different surgical methods, patients were divided into the LPD group ( n=122) and the OPD group ( n=264). The differences in operation time, intraoperative blood loss, postoperative hospital stay, postoperative complications, postoperative oncology survival outcomes and prognosis between groups were compared. Results:Of 386 patients in this study, there were 232 males and 154 females, aged (57.8±11.0) years. The operation time of the LPD group was (330.69±80.55) min which was significantly longer than that of the OPD group (241.13±77.24) min. The intraoperative blood loss 300.00(200.00, 400.00) ml was also significantly less than the OPD group 400.00(262.50, 500.00) ml, and the length of postoperative stay in the LPD group (12.21±5.24) d was significantly less than the OPD group (16.61±6.63) d, (all P<0.05). There were 36 patients (29.51%) in the LPD group and 81 patients (30.68%) in the OPD group who developed postoperative complications, with no significant difference between groups ( P>0.05). Postoperative oncology outcomes showed that the number of lymph nodes dissected in the LPD group was significantly more than that in the OPD group [(12.65±5.03) vs (10.07±5.09)], ( P<0.05). There were no significant differences between the two groups in tumor pathology type, size, degree of differentiation and R 0 resection rates (all P>0.05). All patients were followed up for 6-36 months, with a median follow-up of 20 months. The survival rates of patients with malignant tumors after following-up for more than 1 year in the LPD group was 84.72%(61/72), that in the OPD group was 85.81%(133/155), with no significant difference between groups ( P>0.05). Conclusion:LPD was safe and feasible with its advantages of minimally invasiveness.
RESUMO
Objective:To investigate the consistency of indirect calorimetry, Harris-Benedict (H-B) formula method and rule of thumb in calculating the daily total energy expenditure (TDEE) of patients with acute pancreatitis (AP), and provide the basis for the formulation of reasonable nutritional support program.Methods:A total of 66 AP patients admitted to Henan Provincial People's Hospital from June 2020 to December 2020 were included and retrospectively analyzed, including 35 males and 31 females with an average age of 41.8 years. They were divided into mild acute pancreatitis (MAP) group ( n=20) and moderate to severe AP group ( n=46) according to severity. TDEE was calculated by indirect calorimetry, H-B formula and rule of thumb, and Pearson correlation analysis and Bland-Altman diagram were used to analyze the correlation and consistency of the three methods, respectively. Results:There were no statistical significances in the TDEE of MAP group calculated by indirect calorimetry, H-B formula method and rule of thumb (both P>0.05). TDEE calculated by indirect calorimetry were higher than that of calculated by H-B formula and thumb method both in moderate and severe AP groups, and the difference was statistically significant (both P<0.05). Pearson correlation analysis showed that H-B formula method was positively correlated with the TDEE calculated by indirect calorimetry, and the correlation was 0.61 ( P<0.05). Bland-Altman plot analysis showed the consistence of the two methods. TDEE calculated by rule of thumb was positively correlated with that calculated by indirect calorimetry, and the correlation was 0.75 ( P<0.05). The bland-Altman plot analysis showed a good consistency between the two methods. Conclusion:For MAP patients, TDEE can be calculated by the H-B formula method and rule of thumb. In moderate and severe AP patients, TDEE should be calculated by indirect calorimetry as the basis for the formulation of nutritional support plan.
RESUMO
Objective:To investigate the value of tumor budding in the clinicopathology and prognosis of pancreatic neuroendocrine tumors.Methods:The Cliniccal data of 105 pancreatic neuroendocrine tumor patients underwent resection in Henan Provincial People's Hospital from Jan 2010 to Dec 2016 were retrospectively analyzed. Tumor budding was calculated through hematoxylin-eosin (HE) and immunohistochemical stained slides. Based on the receiver operating characteristic curve (ROC), the number of tumor budding ≥10 was defined as the high-grade budding group, and <10 as the low-grade budding group. Multiple analysis was performed to determine the relationship between tumor budding and clinicopathology as well as prognosis.Results:High-grade budding group was observed in 35 cases and low-grade group in 70. High-grade budding were more common in tumors with advanced T stage, high risk of lymphatic metastasis, preoperative liver metastasis, vascular invasion and postoperative recurrence (respectively χ 2=9.043, 4.286, 10.130, 12.090, 9.260, all P<0.05). Multivariate COX regression analysis showed that tumor budding ( P=0.018), tumor grade ( P=0.026), preoperative liver metastasis ( P=0.042), vascular invasion( P=0.048) was independent risk factors predicting poor prognosis. Conclusion:Tumor budding is highly correlated with clinicopathological parameters which reflect the aggressiveness of pancreatic neuroendocrine tumor, it is also an important prognostic factor.
RESUMO
Objective:To investigate the predictive value of portal vein (PoV) blood circulating tumor cells (CTCs) count in patients with pancreatic cancer on the postoperative prognosis.Methods:The data of 58 patients receiving radical resection of pancreatic cancer and PoV CTCs detection at People's Hospital of Zhengzhou University from Aug 2018 to Jun 2020 were collected. According to the cut-off value of PoV CTCs>10/5 ml made by receiver operating characteristic curve (ROC), patients were divided into high CTCs group and low CTCs group and the differences in clinicopathological parameters and prognosis of the two groups were compared.Results:Postoperative progression-free survival rate of the low CTCs group was higher than that of the high CTCs group ( χ 2=12.97, P<0.001).Univariate COX regression analysis showed that tumor diameter >4 cm, lymph node invasion, TNM staging, CTCs>10/5 ml, postoperative CA199>37 U/m were risk factors for postoperative prognosis. Multivariate COX regression analysis demonstrated that TNM stage ( OR=2.782, P=0.024), CTCs count >10/5 ml ( OR=2.583, P=0.047), postoperative CA199>37 U/m ( OR=3.775, P=0.004) were the independent risk factors of prognosis. Conclusion:A higher PoV CTCs count was a risk factor for poor prognosis of patients with pancreatic cancer after radical resection.
RESUMO
The aim of this study was to investigate the role of tumor-associated neutrophils (TANs) in the metastasis of pancreatic ductal adenocarcinoma (PDAC), to explore the regulation of TANs, and to determine the mechanisms governing the metastasis of PDAC. The correlation between neutrophils and the patient's clinical pathological data was first evaluated. Then, the effects of neutrophils on the invasion of PDAC were analyzed using a combination of conditioned media, direct and indirect coculture of human peripheral blood neutrophils, and PDAC cell lines (Panc-1, MiaPaCa-2 and AsPC-1). The cytokines secreted by neutrophils were detected through ELISA. TAN density was significantly correlated with poor metastasis-free survival (P < .05). Through coculture, it was found that the effect of neutrophils on pancreatic cancer cells was dependent on concentration, and a high concentration of neutrophils showed a lethal effect, while a low concentration of neutrophils primarily promoted the migration ability of cancer cells. The results of the wound-healing assay, the Transwell invasion assay, and laser confocal microscopy confirmed the promoting effect and indicated that the effect of neutrophils toward cancer cells may function indirectly by releasing a series of cytokines. The results of ELISA show that this effect may be achieved through the secretion of a large amount of TNF-α and TGF-ß1 by neutrophils. Our study indicated that neutrophils may increase the metastasis of PDAC by releasing a series of cell cytokines, such as TNF-α and TGF-ß1.

The duration of hospital stay and hospitalization expenses were 24 days (range, 10-45 days) and 9.4×10 4 yuan [range, (5.3-18.7)×10 4 yuan] for all the 25 patients; the above indicators were 36 days, 45 days, 15.1×10 4 yuan, 18.7×10 4 yuan for the 2 patients in Bismuth type Ⅲa, 15 days, 26 days, 33 days, 7.3×10 4 yuan, 11.5×10 4 yuan, 15.9×10 4 yuan for 3 patients in Bismuth type Ⅲb, 24 days, 39 days, 41 days, 12.1×10 4 yuan, 15.2×10 4 yuan, 16.7×10 4 yuan for the 3 patients in Bismuth type Ⅳ, respectively. (3) Follow-up: 25 patients were followed up for 2-36 months, with a median follow-up of 16 months. Of the 25 patients, 18 had no recurrence or metastasis, 2 patients in Bismuth type Ⅳ had extensive intraperitoneal metastasis, 1 patients in Bismuth type Ⅲa had trocar hole metastasis, and 4 patients died. Conclusions:Laparoscopic radical resection of hilar cholangiocarcinoma is safe and feasible. Surgeries should be selected strictly based on surgical indications and the Bismuth type.
RESUMO
Objective To evaluate the clinical application value of portal vein implantation pump for chemotherapy in patients with intrahepatic cholangiocarcinoma (ICC) after radical surgery.Methods The clinical data of 97 patients with ICC who underwent radical surgery in Henan People's Hospital from June 2012 to June 2016 were retrospectively analyzed.Results Among the 97 patients,14 patients received portal venous pump chemotherapy (portal group),33 patients received peripheral venous chemotherapy (peripheral group),and 50 patients did not receive postoperative chemotherapy (control group).There were no statistically significant differences in gender and age between the three groups.The results of survival analysis indicated that the disease-free survival (DFS) period and overall survival (OS) time in the portal group and the peripheral group were significantly better than that in control group (both P < 0.05).In addition,despite the lack of statistical significance (P > 0.05),for the control of intrahepatic metastasis,portal vein pump chemotherapy was better than that of systemic chemotherapy via peripheral vein,and almost all side effects of chemotherapy in the portal group were lower than those in the peripheral group.Conclusion Portal vein pump chemotherapy can improve the prognosis of intrahepatic bile duct patients,especially for the control of intrahepatic metastasis,and can reduce systemic side effects of chemotherapy.
RESUMO
BACKGROUND: Pancreatic cavernous hemangioma is an extremely rare benign tumor that is difficult to diagnose on an imaging examination, and its histopathological examination has rarely been reported. CASE PRESENTATION: Herein, we present the case of a 63-year-old man who was admitted to the hospital due to left upper abdominal pain and defecation unformed for more than 2 years. None of the positive results obtained from the physical examination could explain his symptoms. The imaging examination indicated a multilocular cyst with septa in the head of the pancreas. The patient underwent a pancreaticoduodenectomy, and the pathologic diagnosis was pancreatic cavernous hemangioma. The histopathological examination showed that the lesion was positive for benign vascular markers, such as CD31, CD34 and F8, and negative for lymphocyte markers, such as D2-40. Moreover, it was also positive for ERG and cytokeratin markers, CAM5.2 and AE1/AE3, indicating the complexity of its components, and Ki-67 negativity revealed its benign nature. CONCLUSIONS: Pancreatic cavernous hemangioma has a complex composition that may be reflected not only in the imaging examination but also in the immunohistochemical detection, and it may achieve a good outcome by surgical excision.

Objective To evaluate the role of tumor budding in the prognostic value of intrahepatic cholangiocarcinoma(ICC) after radical resection.Methods The clinicopathological data of patients undergoing radical resection for intrahepatic cholangiocarcinoma between 2011 and 2016 were retrospectively analyzed.The number of tumor budding was counted in a ×200 microscopic field (0.785mm2).Based on receiver operation curve (ROC),the number of tumor budding ≥ 15 was defined as high-grade group,and < 15 was low-grade group.Multivariate analysis were performed on predictors of the tumor.Results Low-grade group was observed in 32 cases and high-grade group in 50.High-grade group appeared to develop tumors with higher CA199,poor differentiation,larger tumor diameter,advanced stage and high risks of lymphnode metastasis (respectively x2 =5.470,4.359,5.101,4.696,5.960,all P < 0.05).Univariate analysis showed that tumor budding,CA199,differentiation,tumor diameter,T classification and lymphnode metastasis were related to the overall survival of patients with ICC (respectively x2 =11.704,4.876,5.056,5.152,8.442,16.725,all P < 0.05).On multivariable analysis,high-grade group was a significant independent predictor of worse OS (HR =2.707 95% CI 1.558-4.705,P < 0.001).Conclusions High-grade tumor budding is an important negative prognostic factor for ICC.
RESUMO
Objective To evaluate fusion indocyanine green fluorescence imaging in laparoscopic anatomical hepatectomy.Methods The clinical data of 75 liver cancer patients undergoing laparoscopic anatomic hepatectomy (LAH) at the Department of Hepatobiliary and Pancreatic Surgery,Henan Provincial People's Hospital from Apr 2017 to Sep 2018 were retrospectively analyzed.Patients were divided into the indocyanine green fluorescence fusion imaging technique (FIGFI-LAH) group (35 cases) and laparoscopic anatomical hepatectomy (LAH) group (40 cases).Results Pathologically positive margin was found in 1 case in FIGFI-LAH group and 9 cases in LAH group (x2 =4.649,P =0.031).There were no significant differences in the mean operative time,intraoperative blood loss,blood transfusion rate,and rate of conversion to open surgery (P > 0.05).Conclusion The use of FIGFI technique in laparoscopic anatomical hepatectomy for liver cancer effectively reduces the positive rate of surgical margin.
RESUMO
Objective To investigate the clinical application value of fluorescence laparoscopy in radical resection of hepatocellular carcinoma (HCC).Methods Data of totally 113 patients with HCC in Henan Provincial People's Hospital between June 2016 to June 2018 were retrospectively analyzed.Among the 113 patients,46 patients underwent laparoscopic hepatectomy (LLR),and 67 patients underwent fluorescence guided laparoscopic hepatectomy (FLLR).Results No significant differences were observed between LLR group and FLLR group in terms of age,male proportion,liver function classification,surgical resection methods,and operation time (P>0.05).The positive ratio of specimen surgical margin in LLR group was significantly higher than that in FLLR group,13.0% vs.3.0%,and the difference was statistically significant (P<0.05).In the FLLR group,22 patients received fluorescence guided anatomic hepatectomy with indocyanine green (ICG),10 with positive staining and 12 with negative staining,and fluorescence imaging was observed 2 minutes after ICG injection.There was no significant difference in operation time,hospitalization cost and length of stay between positive and negative staining (P> 0.05).Conclusion Fluorescence laparoscopy has certain advantages in hepatectomy,and can display the boundary of hepatocellular carcinoma in real time to ensure the safe margin of tumor resection.
RESUMO
Recently, increasing evidence has indicated that the presence of tumor infiltrating immune cells has shown predictive significance for many solid tumors. Present study was performed to evaluate the predictive value of stromal tumor-infiltrating lymphocytes (TILs) for the presence of liver metastasis and overall survival in PDAC (pancreatic ductal adenocarcinoma) patients after complete resection and to explore the potential role of lymphocytes in PDAC. A total of 155 resectable patients with PDAC were enrolled in our study. Stromal TIL density was investigated in hematoxylin and eosin-stained sections of surgical specimens and scored. The effect and possible mechanism of lymphocytes on cancer cells was evaluated using co-culture techniques and ELISA test. Stromal TIL negative status (HR = 2.80, 95% CI 1.75-4.48, P < 0.01) was not only an independent predictor of worse OS (HR = 2.7, 95% CI 1.80-4.06, P = <0.01) but also a significant independent predictor of liver metastasis. Higher CEA (P = 0.01) or CA19-9 (P = 0.01) levels were associated with low stromal TIL density. Stromal TIL negative patients appeared to develop tumors with a higher CEA (P = 0.01), larger diameter (P = 0.05) and advanced stage (P = 0.02). The co-culture experiment suggests that lymphocytes can inhibit pancreatic cancer cell proliferation. Further ELISA and cell culture test indicate that lymphocytes may cause pancreatic cancer cells apoptosis through TNF-alpha secretion. Our data suggest a potential favorable role of stromal TILs in predicting liver metastasis and overall survival of patients with PDAC after complete resection. Lymphocytes may inhibit the growth of PDAC through TNF-alpha secretion, which suggest a potential therapeutic approach against PDAC.
