RESUMO

Objective: Lenvatinib was the standard first-line therapy for patients with unresectable HCC. PD-1 blockades demonstrated promising efficacy for patients with previously-treated HCC. Therefore, this study was to investigate the feasibility and tolerability of lenvatinib plus PD-1 blockades for patients with unresectable HCC retrospectively. Methods: A total of 37 patients with unresectable HCC who received lenvatinib plus PD-1 blockades in first-line setting were included in this study retrospectively. Efficacy of the patients was evaluated with the change of target lesion using mRECIST criteria per investigator and all the subjects were followed up regularly. Adverse reactions were collected and documented. Exploratory analysis between prognosis and baseline characteristics was performed using log rank test and multivariate analysis were performed using Cox regression analysis. Results: The best overall response of the 37 patients suggested that complete response was observed in one patient, partial response was noted in 11 patients, stable disease was noted in 16 patients and 9 patients had progressive disease, which yielded an objective response rate (ORR) of 32.4% (95%CI: 18.0-49.8) and a disease control rate (DCR) of 75.7% (95%CI: 58.8-88.2). Furthermore, the median progression-free survival (PFS) of the 37 patients with advanced HCC was 8.3 months (95%CI: 3.34-13.26). And the median overall survival (OS) was 17.8 months (95%CI: 7.19-28.41). In addition, the median duration of response (DoR) in 12 patients with response was 9.6 months (95%CI: 3.03-16.17). Furthermore, adverse reactions that were attributed to the combination administration were detected in 36 patients (97.3%), among whom a total of 22 patients (59.5%) were observed of the grade ≥3 adverse reactions. And the most common adverse reactions were hypertension, fatigue, nausea and vomiting, and hepatotoxicity. Conclusion: Lenvatinib plus PD-1 blockades demonstrated promising anticancer activity and acceptable toxicity for patients with unresectable HCC. And the conclusion should be validated in prospective clinical trials subsequently.

RESUMO

AIMS: The aim of this study is to evaluate the therapeutic efficacy of Appleby operation for carcinoma of the body and tail of pancreas. MATERIALS AND METHODS: From March 2010 to February 2015, Appleby operation was performed in 17 patients with carcinoma of the body and tail of pancreas. The values of fasting plasma blood, body weight (BW), visual analog pain intensity scale (VAS score), and the quality of life indices were evaluated before and 1 day, 1, 2, 6 weeks after surgery. Survival time, tumor recurrence time, hospitalization time, and treatment-related complications were analyzed. RESULTS: There was no hospital mortality. Pancreatic fistula and diarrhea were major and most frequent. The rate of morbidity in general was 47.1%. After operation, all of the patients were completely pain-free. The VAS score decreased more after surgery comparing with before (83.2 ± 8.5 vs. 1.9 ± 3.6, P < 0.05). After operation, patients gained more than their preoperative BW with a mean increment of (4.1 ± 1.3 kg) (68.1 ± 4.3 vs. 64.0 ± 6.7, P < 0.05). A significant rise of the overall quality of life index was observed after surgery (93.8 ± 9.7 vs. 68.6 ± 6.7, P < 0.05). The 1-, 2-, 3-, and 5-year recurrence rates were 22.9%, 58.9%, 72.6%, and 72.6%, respectively. The 1-, 2-, 3-, and 5-year survival rates after operation were 80.4%, 54.2%, 32.5%, and 16.3%, respectively. CONCLUSIONS: Appleby operation is both safe and effective with regard to pain relief and improvement of overall quality of life. Appleby operation can also achieve a high survival rate and a long overall survival time.

RESUMO

BACKGROUND We aimed to identify pivotal genes and pathways involved in pancreatic ductal adenocarcinoma (PDAC), and explore possible molecular markers for the early diagnosis of the disease. MATERIAL AND METHODS The array data of GSE74629, including 34 PDAC samples and 16 healthy samples, was downloaded from GEO (Gene Expression Omnibus) database. Then, the DEGs (differentially expressed genes) in PDAC samples were compared with healthy samples using limma (linear models for microarray). Gene functional interaction networks were analyzed with Cytoscape and ReactomeFIViz. PPI networks were constructed with Cytoscape software. In addition, PPI (protein-protein interaction) network clustering modules were analyzed with ClusterONE, and the KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway enrichment analyses for modules were performed. RESULTS A total of 630 upregulated and 1,002 downregulated DEGs were identified in PDAC samples compared with healthy samples. Some ribosomal protein genes with higher average correlation in module 0 were enriched in the ribosome pathway. NUP107 (nucleoporin 107 kDa) and NUP160 (nucleoporin 160 kDa) were enriched in module 3. HNRNPU (heterogeneous nuclear ribonucleoprotein U) with higher average correlation in module 8 was enriched in the spliceosome pathway. The ribosome pathway and the spliceosome pathway were significantly enriched in cluster 1 and cluster 2, respectively. CONCLUSIONS Ribosomal protein genes Nup170, Nup160, and HNRNPU, and the ribosome pathway as well as the spliceosome pathway may play important roles in PDAC progression. In addition, ribosomal protein genes Nup170, Nup160, and HNRNPU may be used as possible molecular markers for the early diagnosis of the disease.

RESUMO

OBJECTIVE: A case-control study was conducted to investigate the feasibility and safety of hand-assisted laparoscopic total gastrectomy (HALTG) with D2 lymphadenectomy for gastric cancer as opposed to traditional open total gastrectomy (OTG). METHODS: One hundred fifty-four patients suffering cardia, upper, middle, or whole gastric cancer operated in our department from February 2009 to February 2012 were divided into 2 groups: the open total gastrectomy group (the OTG group) and the hand-assisted laparoscopic total gastrectomy group (the HALTG group). Operative time, estimated blood loss, number of lymph node retrieval, time to the first flatus, and postoperative hospital stay were compared between the 2 groups. RESULTS: HALTG was associated with significantly less operative blood loss, shorter time to the first flatus and shorter postoperative hospital stay, but longer operative time, compared with OTG. There were no significant differences in tumor size, retrieved lymph nodes, American Joint Committee on Cancer/Union International Control Cancer staging and tumor location between the 2 groups. Negative resection margins were obtained in all patients who had undergone a hand-assisted laparoscopic gastrectomy (100%) and in all but 2 patients in the open group (97.6%). The overall observed 5-year survival rate was 56.5% in the HALTG group and 51.8% in the OTG group (P=0.0001, log-rank test). CONCLUSIONS: HALTG is a safe, feasible, and oncologically sound procedure and has advantages over ODG.

RESUMO

BACKGROUND: MicroRNAs (miRNAs) play key roles in tumor development and progression. The aim of this study was to explore the expression levels of miR-34a and miR-217 in hepatocellular carcinoma (HCC) and to further investigate the clinicopathological and prognostic value of miR-34a and miR-217. METHODS: The expression levels of miR-34a and miR-217 were evaluated using quantitative real-time PCR (qRT-PCR). Associations between these miRNAs expression and clinicopathological features were analyzed. Survival rate was determined with Kaplan-Meier and statistically analyzed with the log-rank method between groups. RESULTS: We found that miR-34a expression was significantly downregulated in HCC tissues (P<0.05). Reduced expression of miR-34a was associated with vascular invasion, and advanced TNM stage (P<0.05). Kaplan-Meier revealed that reduced expression of miR-34a was associated with poor overall survival (log-rank test, P<0.05). We found that miR-217 was downregulated in HCC tissues. Decreased expression of miR-217 was remarkably correlated vascular invasion, and advanced TNM stage (P<0.05). Kaplan-Meier analysis and log-rank test showed that HCC patients with low expression of miR-217 was associated with shorter overall survival than patients with high expression (log-rank test, P<0.05). CONCLUSIONS: Our data showed that downregulation of miR-34a and miR-217 was associated with HCC progression and both of them may act as tumor suppressor in HCC.

RESUMO

AIM: Emerging evidence has showed that long non-coding RNA (lncRNA) play an important role in the occurrence and development of various cancers. In the present study, the expression level of lincRNA-p21 was investigated in hepatocellular carcinoma (HCC), and its role in invasion of HCC was also explored. METHODS: The lincRNA-p21 levels in human HCC tumor tissue and cell lines HepG2 and SMMC-7721 were determined by real-time polymerase chain reaction. Transfected HCC cells with pcDNA-lincRNA-p21 or si-lincRNA-p21 for overexpression or downregulation of lincRNA-p21, the Notch signaling and epithelial-mesenchymal transition (EMT)-related proteins and cell invasion were measured by western blot and Transwell assay, respectively. A tumor xenotransplant mouse model was also established to investigate the role of lincRNA-p21 in tumor metastasis in vivo. RESULTS: The lincRNA-p21 expression was downregulated in HCC tissue and cells. Overexpression of lincRNA-p21 inhibited Notch singling and EMT, while its downregulation led to the reverse result. The invasion of HCC cell was also inhibited by pcDNA-lincRNA-p21, and activation of Notch signaling reversed this effect. In vivo, overexpression of lincRNA-p21 decreased the tumor metastasis, as well. CONCLUSION: lincRNA-p21 was downregulated in HCC and lincRNA-p21 overexpression contributed to the inhibition of tumor invasion through mediating Notch signaling induced EMT.

RESUMO

We evaluated miR-371-5p expression in gastric cancer (GC) tissues and its influence on the expression of downstream genes, especially SOX2. MiR-371-5p expression (measured using qRT-PCR) was upregulated in GC tissues and correlated positively with TNM staging and lymph node (LN) metastasis. MiR-371-5p expression was higher in human GC cell lines (AGS, MKN-28, BGC-823, MGC-803, SGC-7901 and MKN-45) than in human normal gastric epithelial (GES-1) cells (all P < 0.05). MGC-803 tumor cell growth (measured with an MTT assay), migration, and invasion (measured with Transwell chamber assays) were severely inhibited in cells transfected with a miR-371-5p inhibitor, whereas they were stimulated in cells transfected with SOX2 siRNA or miR-371-5p inhibitor + SOX2 siRNA. Expression of SOX2 mRNA and protein (assessed with qRT-PCR and Western blot) were greatly enhanced in the miR-371-5p inhibitor group. These results indicate that miR-371-5p expression is strongly upregulated in GC tissues and negatively correlated with SOX2 expression, while miR-371-5p expression is inversely related to proliferation, TNM stage, and LN metastasis of GC cells. Suppression of miR-371-5p may inhibit the growth and invasion of MGC-803 GC cells by upregulating SOX2 expression.

RESUMO

SUMOylation and deSUMOylation are dynamic mechanisms regulating a spectrum of protein activities. The SUMO proteases (SENP) remove SUMO conjugate from proteins, and their expression is deregulated in cancers. SENP2 has been reported to play a critical role in the control of hepatocellular carcinoma (HCC) cell growth by modulating the stability of ß-catenin. However, the underlying mechanism remains largely unknown. Here, we show that the WW domain-containing oxidoreductase (WWOX), a novel inhibitor of the Wnt/ß-catenin pathway, is required for stabilization of ß-catenin regulated by SENP2 in HCC cells. The transcriptional level of WWOX is tightly regulated by SENP2. Moreover, knockdown of WWOX by siRNA attuned SENP2-induced ß-catenin degradation and decreased SENP2-mediated HCC cell proliferation arrest. Taken together, our data suggested that WWOX is a key downstream modulator of the SENP2 tumor suppressor function in HCC cell.

RESUMO

BACKGROUND: Budd-Chiari syndrome (BCS) is characterized by liver sinusoidal congestion, ischemic liver cell damage, and liver portal hypertension caused by hepatic venous outflow constriction. The aim of this research was to investigate the clinicopathological features of BCS-associated hepatocellular carcinoma (HCC) and explore its surgical treatment and prognosis. METHODS: Clinical data from 38 patients with BCS-associated HCC who were surgically treated in our hospital from July 1998 to August 2010 were retrospectively analyzed. The clinicopathological features and prognosis of patients with BCSassociated HCC and surgical treatment for BCS-associated HCC were investigated. RESULTS: Compared to the patients with hepatitis B virus (HBV)-associated HCC, the patients with BCS-associated HCC showed a female predominance, and had significantly higher cirrhosis rate, higher incidence of solitary tumors, lower incidence of infiltrative growth, higher proportion of marginal or exogenous growth, lower rate of portal vein invasion, and higher degree of differentiation. Median survival was longer in patients with BCS-associated HCC (76 months) than in those with HBV associated HCC (38 months). Of 38 patients with BCS-associated HCC, 22 patients who received combined surgery mainly by liver resection plus cavoatrial shunts exhibited hepatic venous outflow constriction relief, while the other 16 patients only underwent liver resection. The combined surgery group had significantly longer survival and lower incidences of post-operative lethal complications (P < 0.05). Multivariate analysis showed that relief of hepatic venous outflow obstruction was a protective factor for survival of patients with BCS-associated HCC, whereas portal vein invasion was a risk factor. CONCLUSIONS: BCS-associated HCC has a more favorable biological behavior and prognosis than HBV-associated HCC. For patients with BCS-associated HCC, tumor resection accompanied with relief of hepatic venous outflow obstruction can reduce the incidence of complications and extend survival.

RESUMO

BACKGROUND & AIMS: We aimed at investigating the effects of the targeted transduction of the Wtp53-pPRIME-miR30-shRNA gene into liver cancer cells, under the mediation of anti-alpha fetoprotein scFv-directed lentivirus, and the inhibitory effect of this system on liver cancer cells. METHODS: The result of infection was observed by fluorescence microscopy. Polymerase chain reaction and Western blotting were used to demonstrate the successful transduction and transcription of the Wtp53-pPRIME-miR30-shRNA-IGF1R gene. Cell growth was observed via the Cell-Counting Kit-8 Method, and cell apoptosis was detected by terminal deoxynucleotidyl transferase biotin-dUTP nick end labeling. To observe further the effects of AFP-Wtp53-pPRIME-miR30-shRNA-IGF1R therapy in animals, models of BALB-C nude mice bearing subcutaneous human hepatocellular carcinoma were established. The influence of the growth of subcutaneously transplanted tumor, expression of Wtp53 protein, apoptosis, and microvessel formation on the overall level of AFP-Wtp53 pPRIME-miR30-shRNA-IGF1R were also evaluated. RESULTS: Recombinant lentivirus was successfully constructed, and its functional plaque-forming unit titer was determined as 4.58 × 10(9)plaque-forming units/ml. A positive strand was detected by polymerase chain reaction and Western blotting. Lentiviral construction worked effectively in AFP-positive liver cancer cells. In vitro and in vivo experiments showed that the recombinant lentivirus was more efficacious in inhibiting the proliferation of Hep3B cells. CONCLUSIONS: The Wtp53-pPRIME-miR30-shRNA gene can be subjected to targeted transduction into liver cancer cells under the mediation of anti-alpha fetoprotein scFv-directed lentivirus. The Wtp53-pPRIME-miR30-shRNA system has targeting ability and lethal effects on liver cancer cells.

RESUMO

Matrine is the major active component of the traditional Chinese medicine Sophora flavescens, but the molecular mechanisms of matrine on tumor invasion inhibition remain unclear. The aim of this study is to elucidate the effects of matrine on invasion ability of human hepatocellular carcinoma (HCC) cells, matrix metalloproteinase-9 (MMP-9), and nuclear factor (NF)-kappa B expression. The expression activity of MMP-9 was measured by reverse transcription polymerase chain reaction, Western blot, and gelatin zymography analysis. The expression of NF-kappa B was measured by the Western blot analysis. Matrine significantly inhibited MMP-9 expression of SMMC-7721 cells. NF-kappa B inhibitor PTDC induced a marked reduction in MMP-9 expression, and it suggested that NF-kappa B could play an important role in MMP-9 expression. Furthermore, matrine significantly suppressed NF-kappa B expression and the invasion of SMMC-7721 cells. Our results showed that matrine inhibited MMP-9 expression and the invasion of human HCC cells. The inhibitory effects are partly associated with the downregulation of the NF-kappa B signaling pathway.

RESUMO

BACKGROUND: Few reports have evaluated the efficacy of re-operation for relapse after initial surgery for hepatocellular carcinoma (HCC) with bile duct thrombosis (BDT). The aim of this study was to investigate the efficacy of initial surgery and subsequent re-operation for HCC with BDT, and their effects on prognosis. METHODS: The clinical data of 880 patients with HCC, including 28 patients with BDT, who underwent radical hepatectomy between 1998 and 2008 in our hospital, were reviewed. The effects of BDT and re-operation on prognosis were retrospectively analyzed. RESULTS: The 1-, 3- and 5-year survival rates were 89.3%, 46.4% and 21.4%, respectively, in 28 patients with BDT versus 91.4%, 52.9% and 20.9% in 852 patients without BDT (P>0.05). Six patients with BDT underwent re-operation after disease relapse, and their survival time was significantly longer than those who did not undergo re-operation (P<0.05). Multivariate analysis indicated that portal vein invasion and tumor size were independently associated with tumor relapse and prognosis (P<0.05). Univariate analysis and multivariate analyses showed that obstructive jaundice was not significantly correlated with tumor relapse or prognosis (P>0.05). CONCLUSIONS: Hepatectomy plus BDT removal is an effective treatment option for HCC with BDT. Obstructive jaundice is not a contraindication for surgery. Re-operation after relapse can provide good outcomes if the cases are appropriately selected.

RESUMO

OBJECTIVE: To observe the expression of antibodies of cytokeratin 19 and 20 in lymph node micrometastasis in patients with extrahepatic cholangiocarcinoma (EHCC), evaluate the prognostic significance of lymph node (LN) micrometastasis and study the correlation between lymph node micrometastasis and clinicopathological features, CA19-9 and CEA. METHODS: A total of 279 lymph nodes was intra-operatively collected from 59 EHCC patients and routine histological examination performed. Immunohistochemical staining was performed on all samples by the murine antibodies of anti-CK19 and anti-CK20 respectively. Then the micrometastasis was identified microscopically according to the color of cells. The results were analyzed according to clinical, pathological and follow-up data. And the relation of micrometastasis with clinical pathological factors and its impact upon survival rate were analyzed. RESULTS: Among 59 EHCC patients, 14 (23.72%) LN metastasis were found with HE staining and 21 micrometastases with CK staining. The incidence of nodal involvement in 59 EHCC patients increased from 5.37% (15/279) by HE staining to 13.98% (39/279) by CK staining. Among 45 patients not positive for LN metastases with HE staining, CK staining was positive in 7 patients and the incidence of micrometastasis was 15.56%. The preoperative serum CA19-9 levels in patients with LN micrometastasis was higher than that those without LN metastasis (P < 0.05). And there was a positive correlation between occult nodal micrometastasis and serum concentrations of CA19-9 (r(s) = 0.371, P < 0.05). The histological type and lymphatic vessel infiltration of tumor were the most importance factors for LN micrometastasis through Logistic regression analysis (P < 0.05). CONCLUSION: The CK immunohistochemical staining can detect the micrometastases in HE negative LN. And LN micrometastasis can more accurately predict the prognosis of EHCC patients.

RESUMO

OBJECTIVE: To evaluate the therapeutic efficacy of duodenum-preserving pancreatic head resection (DPPHR) for severe chronic pancreatitis (CP). METHODS: From February 2004 to March 2010, duodenum-preserving resection of pancreatic head was performed in 21 patients with severe CP. A "modified-DPPHR" was carried out in 14 patients of them and a "Frey's DPPHR" in the other 7 patients. The values of fasting plasma blood (FPB), oral glucose tolerance test (OGTT), body weight (BW), visual analogue pain intensity scale (VAS score) and the quality of life indices were evaluated before and 6(th) month after surgery. RESULTS: There was no hospital mortality. The complications from adjacent organs were resolved definitively. Pancreatic fistula was the major and the most frequent morbidity occurring in 23.8% of the patients. After operation 85.7% of the patients were completely pain-free and 14.3% had continuing abdominal pain. The VAS score decreased more after surgery comparing with before and there was a significant difference (81.1 ± 5.6 vs 7.8 ± 3.6, P < 0.05). The value of FPB in post-operative patients was similar to that in pre-operative ones and there was no significant difference [(5.3 ± 0.4) mmol/L vs (5.4 ± 0.4) mmol/L, P > 0.05]. The value of 2 h-OGGT in post-operative patients was also similar to that in pre-operative ones and it did not differ significantly [(8.0 ± 0.6) mmol/L vs (7.9 ± 0.6) mmol/L, P > 0.05]. After operation 77.8% of patients gained more than 5% of their pre-operative body weight with a mean increment of (4.8 ± 0.7) kg (58.8 ± 1.8 vs 53.9 ± 2.0, P < 0.05). A significant rise of the overall quality of life index was observed after surgery (78.1 ± 7.3 vs 61.0 ± 6.2, P < 0.05). CONCLUSION: DPPHR is both safe and effective with regard to pain relief, a definitive control of complications affecting adjacent organs and an improvement of overall quality of life. It leads to no further deterioration of pancreatic functions.

RESUMO

BACKGROUND/AIMS: Resveratrol, a polyphenolic phytochemical present in berries, grapes, and wine, has emerged as a promising chemopreventive candidate. The aim of the present study was to determine the inhibitory effect of resveratrol on vascular endothelial growth factor (VEGF) expression and angiogenesis in hepatocellular carcinoma (HCC) and to explore its mechanism. METHODOLOGY: VEGF protein was detected by western blot, whereas VEGF mRNA expression was investigated by RT-PCR. Nuclear factor-kappa B (NF-kappa B) was measured by electrophoretic mobility shift assay (EMSA). Xenograft sections were stained for CD34 to study microvessels in vivo. RESULTS: We found that VEGF protein and mRNA expressions in the cells treated with resveratrol were significantly decreased. The activation of NF-kappa B was also intensely inhibited by resveratrol. Growth of tumours in nude mice was inhibited by resveratrol. Microvessel density was decreased with resveratrol treatment. CONCLUSIONS: The inhibitory effect of resveratrol on VEGF activity may occur partly through suppression of the activation of NF-kappa B in HepG2 cells. Resveratrol also significantly inhibited tumour growth and angiogenesis.

RESUMO

OBJECTIVES: To investigate the expression of Survivin in patients with extrahepatic cholangiocarcinoma (EHCC) and its relationship with clinicopathological features of EHCC, and the correlation between the expression of Survivin and lymph node micrometastasis, tumor markers, and the prognosis of EHCC. METHODS: The expression of Survivin protein in paraffin-embedded specimens of 59 patients with EHCC and their 20 para-carcinoma tissues were evaluated by S-P method of immunohistochemical staining. The correlation between the expression of Survivin and the lymph node micrometastasis, clinicopathological features of EHCC and the prognosis of EHCC were analyzed. RESULTS: The positive expression rate of Survivin protein was 67.8% (40/59) in paraffin-embedded specimens of 59 patients with EHCC and was 20.0% (4/20) in para-carcinoma tissues, and difference between carcinoma tissues and para-carcinoma tissues was significant (P<0.01). Histological differentiation in EHCC had a negative correlation with the expression of Survivin protein, while the expression of Survivin protein in EHCC had a positive correlation with TNM of EHCC, lymphatic vessel infiltration, lymph node metastasis and perineural invasion (P<0.05). The serum CA19-9 levels in the positive group with expression of Survivin protein was (290,300+/-55 500) U/L and was obviously higher than that in the negative group [(113,300+/-31,400) U/L, P<0.05]. The mean survival time of the patients with negative expression of Survivin protein was higher than that of the patients with positive expression (43.5 vs. 21.1 months, P<0.01). Screened to significance univariate, the multivariate analysis through Cox proportional hazard model analysis showed that lymph node metastasis, residual tumor margins, and expression of Survivin protein were independent prognosis factors of the patients with EHCC (P<0.05, P<0.01, P<0.01). CONCLUSIONS: The expression of Survivin protein in EHCC has a negative correlation with histological differentiation, while has a positive correlation with lymphatic vessel infiltration and serum CA19-9 concentrations. The expression of Survivin protein maybe an independent prognosis factor of the patients with EHCC.

RESUMO

OBJECTIVE: To evaluate the therapeutic efficacy of interposition of graft meso-cavo-atri shunt (MCAS) for the treatment of Budd-Chiari syndrome (BCS) with occlusion of both inferior cava vena (ICV) and hepatic veins (HVs). METHODS: 51 BCS patients with combined occlusion of ICV and HVs, 30 males and 20 females, aged 18-45, underwent MCAS. A 16-18 mm ring-reinforced graft (main graft) was anastomosed firstly to the side of ICV with continuous 5/0 vascular suture, then to the side of the right atrium with continuous 5/0 vascular suture. A 10-12 mm graft (secondary graft) was anastomosed to the side of the superior mesenteric vein (SMV) with continuous 5/0 vascular suture, then to the side of the main graft with continuous 5/0 vascular suture. The pressure and blood flow of ICV and portal vein (PV) were examined before and after operation. The patients were followed up for 6 months to 16 years. RESULTS: There was no perioperative death. During the follow-up no thrombosis of the main graft was found but thrombosis of the secondary graft occurred in two cases. The patency rates of the main and secondary grafts were 100% and 96.1% respectively. The total patency rate of graft was 96.1%. After operation the pressure of IVC and PV decreased by 17.4 +/- 5.7 cm HO2O and 17.0 +/- 7.0 cm H2O respectively compared with those before operation. CONCLUSION: MCAS is very effective in decompression of PC and IVC. MCAS may be a valuable surgical procedure for treatment of BCS with occlusion of both ICV and HVs.

RESUMO

BACKGROUND & OBJECTIVE: The excision rate is low for the intermediate and advanced pancreatic head carcinoma. Comprehensive treatment is the main method to prolong patient's life. The objective of this study was to discuss the effect of intraoperative and postoperative radiotherapy on intermediate and advanced pancreatic head carcinoma. METHODS: Twenty-seven patients with intermediate or advanced pancreatic head carcinoma underwent cholecystojejunostomy combined by intraoperative radiotherapy with direct electron beam on the tumor. Meanwhile the catheter of multifunctional implantable drug delivery system was inserted via gastroduodenal artery for postoperative perfusion chemotherapy. The survival rate was calculated using the direct method after follow-up for 3-29 months. RESULTS: All carcinoma shrank with 100% pain releasing rate. The 6-, 12-,and 24-month survival rates were 100%, 93.7%, and 20%, respectively. Five patients died and the average survival period was 17.9 months. CONCLUSION: Intraoperative radiotherapy combined with perfusion chemotherapy is an effective method to prolong the life of the patients with intermediate or advanced pancreatic head carcinoma.
