Background: To provide a quantitative assessment of the association between body mass index (BMI) and the risk of gastric cancer, we summarized the evidence from prospective studies.Methods: Eligible studies published up to November 30, 2012, were retrieved via computer searches of MEDLINE and EMBASE as well as manual review of references. Summary relative risks (SRR) with their corresponding 95% confidence intervals (CI) were calculated using a random-effects model.Results: A total of 24 prospective studies of BMI and gastric cancer risk with 41,791 cases were included in our analysis. Overall, both overweight (BMI, 25–30 kg/m2) and obesity (BMI, ≥30 kg/m2) were not associated with risk of total gastric cancer (overweight: SRR, 1.01; 95% CI, 0.96–1.07; obesity: SRR, 1.06; 95% CI, 0.99–1.12). Furthermore, we found increased BMI was positively associated with the risk of gastric cardia cancer (GCC; SRR = 1.21 for overweight and 1.82 for obesity), but not with gastric non-cardia cancer (GNCC; SRR = 0.93 for overweight and SRR = 1.00 for obesity). Similar results were observed in a linear dose–response analysis.Conclusion: On the basis of meta-analysis of prospective studies, we find high BMI is positively associated with the risk of GCCs but not with GNCCs.Impact: (i) On the basis of more definite and quantitative evidence than previously available, we found that increasing BMI was not a clear risk factor for total gastric cancer. (ii) Increased BMI was positively associated with risk of GCC but not with GNCCs. Cancer Epidemiol Biomarkers Prev; 22(8); 1395–408. ©2013 AACR.

A full understanding of the clinical manifestations and risk factors for hepatic abscesses with biloma formation after transcatheter arterial chemoembolization (TACE) is crucial for accurate diagnosis and effective therapeutic intervention.11,524 patients with hepatic tumors were treated with TACE. 84 patients were diagnosed with hepatic abscesses after TACE, and 35 progressed to hepatic bilomas and were treated with percutaneous transhepatic drainage (PTD) and/or percutaneous transhepatic cholangiography and drainage (PTCD). Clinical features, blood samples, bacterial cultures, and imaging data were collected, and incidence, risk factors, therapeutic effects, and prognostic indicators were analyzed.The incidence of biloma in patients with liver abscesses was 41.7% with an average diagnosis time of 12.3 ± 3.2 days. 71.4% of patients complained of abdominal pain, and 63.7% had metastatic liver cancer. In the latter patients, clinical features included multiple abscess lesions with a poor blood supply to the tumor and large necrotic lesions. The original tumors were primarily in the digestive system (87.0%). The mean diameter of the largest lesions was 6.5 ± 2.3 cm. Before abscess formation, the Child-Pugh liver function classification was grade A in 14 cases and grade B in 21 cases. Escherichia coli was the most frequently seen infectious bacteria. Liver function was significantly compromised by the occurrence of hepatic abscesses. The mean survival time after diagnosis of liver abscesses in all patients was 11.5 ± 0.6 months. The causes of death included abscess (n = 9, 25.7%), tumor (n = 22, 62.9%), and other causes (n = 4, 11.4%). Risk factors included tumors, gastrointestinal surgery, and diabetes.PTD and/or PTCD combined with active antibiotics are recommended as the first-line treatment and are effective therapeutic regimens for biloma formation after TACE.

Pancreatic cancer has the worst prognosis of all common cancers. Pancreatic cancer cells have a metabolic advantage due to their swiftly adaptive responses to hypoxic and low-nutrient medium. This advantage contributes to the aggressivity of pancreatic cancer. In this study, lncRNA MIR210HG was abnormally upregulated within pancreatic cancer. It acted as a key oncogenic regulator of pancreatic cancer aggressiveness and glycolysis. Knockdown of MIR210HG significantly inhibited the aggressive phenotype of pancreatic cancer cells and inhibited the growth of xenograft tumours. More importantly, MIR210HG knockdown inhibited pancreatic cancer cell glycolysis via regulating the glycolysis-related hexokinase 2 (HK2) and Pyruvate kinase muscle isozyme M2 (PKM2) expression. Compared with the MIR210HG knockdown group, miR-125b-5p inhibition promoted the aggressive phenotypes and glycolysis of pancreatic cancer cells. Furthermore, the effects of MIR210HG knockdown on HK2 and PKM2 expression, pancreatic cancer cell aggressive phenotypes, and glycolysis were significantly reversed by miR-125b-5p inhibition. In tissue samples, MIR210HG expression was negatively correlated with miR-125b-5p levels and positively correlated with HK2 and PKM2 expression. miR-125b-5p expression was negatively correlated with HK2 and PKM2 expression. In conclusion, MIR210HG affected the phenotypes of pancreatic cancer cells, including proliferation, invasion, migration, and glycolysis, via modulating the miR-125b-5p/HK2/PKM2 axis.

Purpose The purpose of this study was to assess the efficacy of an iodine-125 (125I) seed strand combined with a metal stent compared with a metal stent for treatment of obstructive jaundice caused by pancreatic ductal adenocarcinoma (PDAC). Methods and Materials A retrospective analysis was carried out of patients who were referred to Shanghai Zhongshan Hospital of Fudan University with a diagnosis of PDAC between January 1, 2010 and January 31, 2019. A total of 110 consecutive patients with obstructive jaundice caused by PDAC were divided into the iodine-125 seed strand combined with a metal stent group (Group A = 48) and the metal stent group (Group B = 62). The primary outcome was stent obstruction–free survival time, and secondary outcomes were overall survival and complications. Results The median stent obstruction–free survival time was 133.0 (95% confidence interval (CI): 166.093–149.907) days, and the median overall survival was 212.0 (95% CI: 187.183–236.817) days in all patients. Median stent obstruction–free survival time was 175 days (95% CI 103.165–246.835 days) in Group A versus 120 days (95% CI 87.475–152.525 days) in Group B (p = 0.035). A lower Eastern Cooperative Oncology Group (ECOG) score (p = 0. 000) and iodine-125 seed strand combined with metal stent implantation (p = 0.008) were associated with a longer stent obstruction–free survival time. Obstruction length (p = 0.083), ECOG score (p = 0.000), and iodine-125 seeds (p = 0.037) might have potential impact on stent obstruction–free survival time and were included for multivariable analysis using the Cox proportional hazards model. Stent restenosis was observed in 18.8% (9/48) of patients in Group A and 54.8% (34/62) in Group B, respectively. There was no significant difference in median survival between Group A and Group B (p = 0.409). The median survival in Group A was 209 days (95% CI 150.750–267.250) and 202 days (95% CI 190.624–233.376) in Group B. The median survival of patients with a lower ECOG score was better than that of patients with a higher ECOG score (267 days vs 132 days, p = 0.000). The Grade 3 or 4 complications occurred in 4 (8.3%) of the 48 patients in Group A (one case of hemobilia, one case of liver abscess, two cases of choleperitonitis) and in 5 (8.1%) of the 62 patients in Group B (one case of hemobilia, two cases of liver abscess, two cases of choleperitonitis) (p = 0.972). Conclusions Implantation of an iodine-125 seed strand combined with a metal stent provides longer obstruction-free survival time compared with a metal stent in patients with obstructive jaundice caused by PDAC. It seems reasonable to choose an iodine-125 seed strand combined with a metal stent as a treatment for these patients.

To determine the safety and efficacy of percutaneous intraductal radiofrequency ablation (RFA) combined with biliary metal stent placement for patients with unresectable malignant biliary obstruction. From a cohort of 70 patients with unresectable malignant biliary obstruction, 28 patients received percutaneous intraductal RFA combined with biliary stent placement (group A) and the remaining 42 were treated with biliary metal stent placement only (group B). Stent patency, overall survival (OS), alleviation of jaundice, and postoperative complications were assessed. The technical success rate for both groups was 100%. No severe complications (e.g., biliary bleeding, perforation) occurred. In both groups, jaundice was relieved and the decrease of the total and direct bilirubin concentration was significant (p

Pancreatic cancer is amongst the most lethal malignancies with increasing incidence and mortality worldwide. Distant metastases, especially intrahepatic metastases, is the leading cause of death for pancreatic cancer. Circulating tumor cells (CTCs) are neoplastic cells released from the primary tumor into circulation, and play critical roles in metastases of various types of cancers. Though clinical studies showed that detection of CTCs in peripheral circulation was associated with worse prognosis in patients with breast cancer and hepatocellular carcinoma, detection CTCs in peripheral blood of pancreatic cancer was still challenging due to hepatic filtration and technical limitations. Previous studies have demonstrated that CTCs could be detected in portal vein circulation in patients with pancreaticobiliary carcinoma. In the present study, taking advantage of ultrasonography-guided transhepatic puncture, we analysis CTCs in portal vein blood obtained from patients with advanced pancreatic cancer. CTCs were detected in all 29-portal vein blood of samples, and absolute numbers of circulating pancreatic cancer cells in portal vein was significantly higher than that in peripheral circulation. Furthermore, we found that CTC counts in portal vein was highly associated with intrahepatic metastases and indicated poorer prognosis in patients with advanced pancreatic cancer. Short-term expansion and in vitro drug sensitivity assay showed that CTCs derived from portal vein blood were highly resistant to several chemotherapy regimens. In summary, detection of CTCs in portal vein could be a powerful tool to stratify the risk of intrahepatic metastases of pancreatic cancer, and provided new insight into the biological feature of pancreatic cancer metastases and drug resistance.

Although the American College of Gastroenterology colorectal cancer screening guidelines highlight cigarette smoking as a risk factor, cigarette smoking is still an arguably underappreciated risk factor for this disease, especially for its subsites: colon cancer (CC) and rectal cancer (RC). A literature search of MEDLINE and EMBASE was performed up to 30 April 2013 for prospective cohort studies. A random-effects meta-analysis was carried out to estimate the summary relative risks (SRRs) and 95% confidence intervals (CIs) for the associations. A total of 24 prospective studies, which reported data for cigarette smoking and incidence of CC and RC separately, were included. Our analysis showed that, compared with never-smokers, current smokers had a higher risk of RC than CC (CC: SRR=1.09, 95% CI, 1.01-1.18; RC: SRR=1.24, 95% CI, 1.16-1.39; PRC vs. CC=0.034), whereas former smokers had a similar risk of CC and RC. Current smokers had a significantly higher risk of proximal CC than distal CC (P=0.035). This meta-analysis suggests that cigarette smoking is associated with an increased risk of both CC and RC, and that the magnitude of the association is stronger for RC than that for CC.

The aim of this study was to evaluate the therapeutic efficacy and the safety of transarterial infusion (TAI) with gemcitabine and oxaliplatin in patients with unresectable pancreatic cancer (PC). After celiac arteriogram and super-mesenteric arteriography, 1000 mg/m gemcitabine and 100 mg/m oxaliplatin were infused through 4- or 5-Fr catheters in arteries supplying blood to the tumor. In cases in which the blood-supplying artery could be selectively catheterized, the infusion was performed through a 3-Fr catheter placed in the tumor-supplying artery. Therapeutic courses were repeated every 4 weeks. The tumor response, the overall survival, and adverse effects were monitored. Thirty-two patients with unresectable PC were enrolled in this study, including 20 male and 12 female patients. A total of 105 cycles of TAI (mean=3.3 cycles/patient) were performed. Of 32 patients, partial remission was achieved in eight (25.0%), stable disease in 13 (40.6%), and progressive disease in 11 (34.4%). The overall response rate was 25.0%. The median survival time was 10.0 months (range=4-21 months). Grade III-IV toxicity, vomiting, occurred with a rate of 21.9%. Grade I-II neutropenia, thrombocytopenia, peripheral nerve toxicity, elevated serum transaminases levels, and serum total bilirubin were observed. TAI with gemcitabine and oxaliplatin is well tolerated and highly effective in patients with unresectable PC.

This study is aimed at evaluating the safety and efficacy of transarterial chemoembolization (TACE) for patients with hypervascular painful metastatic spinal tumors refractory to percutaneous vertebroplasty (PVP). A total of 11 patients with hypervascular painful metastatic spinal tumors refractory to PVP were recruited for testing the safety and efficacy of TACE. Individual patients were subjected to infusion with 40 mg/m2 epirubicin and 20–60 mg polyvinyl alcohol foam (PVA) particles (300–500 μm) or gel-foam strips for embolization through the dominant arteries to the tumor. The degrees of pain the patients suffered were evaluated using the visual analogue scale (VAS) score one day before, 5 days, and 2 weeks after TACE. The neurologic symptoms and skin/muscle complications were observed. A total of 12 lumbar vertebrae from 11 patients were treated with TACE through 21 vertebral arteries. Twelve out of 21 arteries were embolized with PVA particles, and other nine arteries were embolized with gel-foam strips. The analgesic rate of TACE in those patients was 90.9 % at 5 and 14 days postprocedure. The VAS scores in those patients were reduced from preoperative 8.6 ± 1.1 to 3.9 ± 1.38 on day 5 and to 3.6 ± 1.7 at 2 weeks post-TACE, respectively. There was no obvious neurologic symptom or skin/muscle necrosis in those patients. Transarterial chemoembolization (TACE) is a safe and effective therapy for pain relief in patients with hypervascular painful metastatic spinal tumors refractory to PVP.

Background Stent occlusion by tumor ingrowth or overgrowth is the main cause of jaundice recurrence after metal stent insertion in patients with malignant obstructive jaundice (MOJ). The application of intraluminal brachytherapy (ILBT) in patients with MOJ results in local control of malignant tumors, which prolong stent patency. Purpose To evaluate the safety of ILBT in pig bile ducts using ribbons of iodine-125 (125I) seeds. Material and Methods Sixteen healthy pigs were randomly assigned to four groups of four pigs each. A 125I seed ribbon was implanted into the common bile duct of each animal through an incision in the duct wall, and was fixed by suturing. The four groups of animals were sacrificed at 15, 30, 60, and 120 days after ribbon implantation, respectively. Serum bilirubin concentrations, alanine aminotransferase concentrations, and white blood cell counts before and after implantation were compared within each group. Pathological changes to the bile duct wall were observed using a light microscope. Morphological changes in biliary epithelial cells and organelles were observed with electron microscopy. Results 125I ribbons were successfully implanted in all animals without surgery-related death. We found no significant difference in pre- and post-implant serum bilirubin, alanine aminotransferase, or white blood cell counts. Light and electron microscopy showed that the most severe bile duct damage occurred in the 15-day group, which exhibited necrosis and detachment of numerous epithelial cells, and infiltration of inflammatory cells. Repair and proliferation of the bile duct epithelium began 30 days after implantation and was nearly complete at 60 days. Conclusion This study demonstrated the safety of ILBT using a 125I ribbon in the pig bile duct. 125I seed ribbons may be used in the treatment of MOJ in humans.

This study is sought to evaluate the feasibility and safety of using ¹²⁵I seed strands for intraluminal brachytherapy (ILBT) in the treatment of malignant obstructive jaundice (MOJ), and its clinical effect on stent patency. A total of 34 patients found to have MOJ were randomly assigned to an ILBT treatment group or a control group before biliary stent insertion. For the ILBT group, ¹²⁵I seed strands were implanted into the obstructive segment of the bile duct after stent insertion. For the control group, only the biliary stent was inserted. Alimentary and hematologic complications were examined for patients in the ILBT group. The stent patency of the two groups were compared. In the ILBT group, the number of ¹²⁵I seeds per strand varied from 6 to 16 (mean, 10.9), and were successfully implanted in 17 patients. Serum levels of bilirubin, alanine aminotransferase, granulocytes, and platelets assayed 2 and 4 weeks following the procedure demonstrated no significant difference between the ILBT group and the control group. The mean stent patency for ILBT group (10.2 months) was significantly longer than that of the control group (7.2 months, p=0.032). ¹²⁵I seed strands for ILBT is a feasible and safe palliative therapy for the treatment of MOJ, and may prolong stent patency.

Transcatheter Arterial Chemoembolization (TACE) is the first line of treatment in inoperable hepatocellular carcinoma. Magnetic affinity beads can be used to extract peptides from un-fractionated serum samples. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) can detect the presence and the molecular mass of peptides. In this study, we used a highly optimized ClinProt-matrix-assisted laser desorption/ionization time-of flight mass spectrometer (MALDI-TOF-MS) to screen hepatocellular carcinoma markers for TACE. 40 sera from 20 patients, including before and after TACE to explore those biomarkers, might be related with therapy efficiency, and some of the patients who received another therapy were analyzed as well. The spectra were analyzed statistically using FlexAnalysis™ and Clin-Prot™ bioinformatic software. The seven most significant differential peaks (p < 0.0.5) were selected out by ClinProTool software to identify hepatocellular carcinoma markers for TACE therapy. Furthermore, the differential peptide of 3883Da was identified as plasma serine protease inhibitor precursor (Protein C inhibitor). This study provides a direct link between peptide marker profiles and TACE therapy, and the markers may have clinical utility for monitoring efficiency of therapy.

Background and aims Quantification of the association between consumption of fruit and vegetables and risk of gastric cancer (GC) is controversial. We aimed to conduct a meta-analysis of cohort studies to evaluate the associations. Methods Eligible studies published up to 31st August 2013 were retrieved via both computer searches of PubMed and EMBASE and a manual review of references. Random-effects models were used to calculate summary relative risk (SRR). Heterogeneity among studies was assessed using Cochran’s Q and I 2 statistics. Results A total of 17 articles (24 studies), were included in this meta-analysis. There were >2.4 million individuals (6632 GC events) with a median follow-up of 10 years. Based on the high versus low analysis, consumption of fruit, but not vegetables, may reduce risk of gastric cancer (fruit: SRR = 0.90, 95% confidence interval (CI): 0.83–0.98, P heterogeneity = 0.450; vegetable: SRR = 0.96, 95% CI: 0.88–1.06, P heterogeneity = 0.150). Meta regression analysis suggested that outcome (incidence versus mortality) and study quality (high versus low) contributed significantly to heterogeneity. The same results were also shown in the linear dose–response analysis (per 100-g/day) (fruit: SRR = 0.95, 95% CI: 0.91–0.99; vegetable: SRR = 0.96, 95% CI: 0.91–1.01). Significant inverse associations emerged in non-linear models for consumption of fruit ( P non-linearity = 0.04), but not for consumption of vegetables ( P non-linearity = 0.551). Conclusions Findings from this meta-analysis indicate a significant protective effect for the consumption of fruit on GC risk, but not for the consumption of vegetables.

Liver biopsy is the "gold standard" for evaluating liver disorders, but controversies over the potential risk of complications and patient discomfort still exist. Using a 21G fine needle, we developed a new biopsy procedure, fine needle aspirating and cutting (FNAC). Our procedure obtains enough tissue for pathological examination and meanwhile, reduces the risk of biopsy complications. The present study was to determine the safety and efficiency of 21G FNAC compared with 18G Tru-cut core needle (TCN) in liver tumor biopsies.Ninety-four patients with unresectable malignant tumors were included in this study. Patients were divided into 2 groups: 18G TCN and 21G FNAC. The total positive rate (TPR) and safety of both groups were compared.TPR was not different between the two groups. Liver puncture track subcapsular hemorrhage and arteriovenous shunt were reported with 18G TCN but not with 21G FNAC. The incidence of pain caused by biopsy was higher for the 18G TCN group compared to the 21G FNAC group (P0.05). About 82.6% of the patients in the 18G TCN group had a sample length0.5 cm, but 52.1% in the 21G FNAC group (P0.05). More than 50% of patients in both groups had sufficient tissue for immunohistochemical examination.TPR is not different between the 21G FNAC and 18G TCN biopsy procedures, but the safety of 21G FNAC is superior to that of 18G TCN. Tissues obtained by either of these two procedures are sufficient for a pathological diagnosis.

Background: To provide a quantitative assessment of the association between body mass index (BMI) and the risk of gastric cancer, we summarized the evidence from prospective studies. Methods: Eligible studies published up to November 30, 2012, were retrieved via computer searches of MEDLINE and EMBASE as well as manual review of references. Summary relative risks (SRR) with their corresponding 95% confidence intervals (CI) were calculated using a random-effects model. Results: A total of 24 prospective studies of BMI and gastric cancer risk with 41,791 cases were included in our analysis. Overall, both overweight (BMI, 25–30 kg/m2) and obesity (BMI, ≥30 kg/m2) were not associated with risk of total gastric cancer (overweight: SRR, 1.01; 95% CI, 0.96–1.07; obesity: SRR, 1.06; 95% CI, 0.99–1.12). Furthermore, we found increased BMI was positively associated with the risk of gastric cardia cancer (GCC; SRR = 1.21 for overweight and 1.82 for obesity), but not with gastric non-cardia cancer (GNCC; SRR = 0.93 for overweight and SRR = 1.00 for obesity). Similar results were observed in a linear dose–response analysis. Conclusion: On the basis of meta-analysis of prospective studies, we find high BMI is positively associated with the risk of GCCs but not with GNCCs. Impact: (i) On the basis of more definite and quantitative evidence than previously available, we found that increasing BMI was not a clear risk factor for total gastric cancer. (ii) Increased BMI was positively associated with risk of GCC but not with GNCCs. Cancer Epidemiol Biomarkers Prev; 22(8); 1395–408. ©2013 AACR.

Background The long-term survival in hepatocellullar carcinoma (HCC) patients after transarterial chemoembolization (TACE) remains dismal due to local and/or regional recurrence as well as distant metastasis. The efficacy of sorafenib in advanced HCC has been demonstrated and brought great hope. Recently, the use of sorafenib in combination with TACE for BCLC stage B and C HCC patients was recommended. However, data on this dual-modality treatment is little, and its advantage over TACE alone has not been addressed. The present study sought to understand the efficacy of the combination of TACE and sorafenib in the treatment of advanced HCC. Methods Between June 2008 and Feb 2011, 45 patients with advanced HCC were enrolled and treated with sorafenib in combination with TACE according to an institutional protocol of the Zhongshan hospital, Fudan University. The control group of 45 other HCC patients with similar characteristics treated with TACE alone in the same period of time in our institute were selected for retrospective comparison of the treatment outcomes especially overall survival time. Adverse reactions induced by sorafenib were observed and recorded. Results The median overall survival time of the combined treatment group was 27 (95% Confidence Interval: 21.9–32.1) months, and that of TACE alone group was 17 months (95% Confidence Interval: 8.9–25.0) months (P = 0.001). Patients required significantly less frequent TACE for their symptomatic treatment after the initiation of sorafenib therapy. The most common adverse events associated with sorafenib were hand-foot skin reaction, rash and diarrhea. Of CTCAE grade IV or V toxicity was observed. Conclusion TACE combined sorafenib significantly prolonged median overall survival time of patients with advanced HCC.

In recent years, increasing evidence has suggested a strong association between diabetes mellitus (DM) and hepatocellular carcinoma (HCC). To provide a quantitative assessment of this association, we performed a systematic review and meta-analysis of cohort studies. We collected studies through a literature search of Medline from January 1, 1966 and EMBASE from January 1, 1974, through July 31, 2010. Summary relative risks (SRRs) with their corresponding 95% confidence intervals (CIs) were calculated using a random-effects model. A total of 25 cohort studies that met our inclusion and exclusion criteria were included in our analysis. Among these, 18 studies showed that DM was associated with an increased incidence of HCC (SRRs = 2.01, 95% CI: 1.61-2.51), compared with individuals without DM. There was a statistically significant heterogeneity among these studies (Q = 136.68, p0.001, I(2) = 87.6%). Analyses subgrouped by controlling confounders revealed that the increased incidence of HCC was independent of geographic location, alcohol consumption, history of cirrhosis, or infections with hepatitis B (HBV) or hepatitis C virus (HCV). In addition, DM was also positively associated with HCC mortality (SRR = 1.56; 95% CI: 1.30-1.87), with no significant evidence of heterogeneity among studies (Q = 1.16, p = 0.56, I(2) =0%). There were no significant publication bias (p = 0.79 for Egger's regression asymmetry test). These findings strongly support a positive association between DM and increased risk of HCC in both males and females.

Background Ginsenoside Rg3 is a low toxic inhibitor of vascular endothelial growth factor (VEGF), which is implicated in angiogenesis in hepatocellular carcinoma (HCC). This single-centre, open-label, randomised, controlled trial evaluated the efficacy and safety of ginsenoside Rg3 plus transarterial chemoembolisation (TACE) in patients with advanced HCC. Methods Advanced HCC patients (Child-Pugh A) who had no prior systemic therapy were randomly assigned (2:1 ratio) to receive 20 mg twice daily orally (n = 152) combined with TACE or TACE alone (n = 76). The primary endpoint was overall survival (OS). Secondary endpoints included time to progression (TTP), time to untreatable progression (TTUP), disease control rate (DCR) based on modified Response Evaluation Criteria in Solid Tumors, and safety. Results Median overall survival was 13.2 months (95% confidence interval (CI) 11.15–15.26) in the TACE + Rg3 group compared with 10.1 months (95% CI 9.14–11.06) for those receiving TACE alone (hazard ratio (HR) 0.63 [95% CI 0.46–0.85], p = 0.002). Median TTP was 4.3 months (95% CI 3.32–5.28) in the TACE + Rg3 group compared with 3.2 months (95% CI 2.51–3.89) in the TACE group (HR 0.82 [95% CI 0.62–1.08], p = 0.151). Patients in the TACE + Rg3 group had longer median TTUP (8.3 months [95% CI 7.05–9.55]) than in the TACE group (7.3 months [95% CI 6.40–8.20]; HR 0.76 [95% CI 0.57–1.02], p = 0.063). The most frequently reported Rg3-related grade 3–4 adverse events in 152 patients were constipation (two [1.3%]) and hypertension (six [3.9%]). The incidence of ascites was lower in the TACE + Rg3 group than in the TACE group (23.7% versus 48.7%, p = 0.002), as was the incidence of anorexia [12.5% versus 44.7%, p = 0.000], fatigue (9.9% versus 50.0% p = 0.000), anaemia (36.8% versus 51.3%, p = 0.037), leukopenia (46.7% versus 76.3%, p = 0.000), thrombocytopenia (32.9% versus 50.0%, p = 0.012), and hyperbilirubinaemia (17.8% versus 34.2%, p = 0.028). Interpretation In patients with advanced HCC and sufficient liver function, median survival was nearly 3 months longer for patients treated with TACE and ginsenoside Rg3 than for those who received TACE only.

AIM: To determine the feasibility and safety of intraluminal brachytherapy in treatment of malignant obstructive jaundice (MOJ) and to evaluate the clinical effect of intraluminal brachytherapy on stent patency and patient survival. METHODS: Thirty-four patients with MOJ were included in this study. Having biliary stent placed, all patients were classified into intraluminal brachytherapy group (group A, n = 14) and control group (group B, n = 20) according to their own choice. Intraluminal brachytherapy regimen included: HDR-192Ir was used in the therapy, fractional doses of 4-7 Gy were given every 3-6 d for 3-4 times, and standard points were established at 0.5-1.0 cm. Some patients of both groups received transcatheter arterial chemoembolization (TACE) after stent placement. RESULTS: In group A, the success rate of intraluminal brachytherapy was 98.0%, RTOG grade 1 acute radiation morbidity occurred in 3 patients, RTOG/EORTC grade 1 late radiation morbidity occurred in 1 patient. Mean stent patency of group A (12.6 mo) was significantly longer than that of group B (8.3 mo) (P < 0.05). There was no significant difference in the mean survival (9.4 mo vs 6.0 mo) between the two groups. CONCLUSION: HDR-192Ir intraluminal brachytherapy is a safe palliative therapy in treating MOJ, and it may prolong stent patency and has the potentiality of extending survival of patients with MOJ.

Clinical application and potential complication of percutaneous transsplenic varices embolization (PTSVE) of esophageal or gastrio-fundal varices in patients with hepatocellular carcinoma (HCC) complicated with portal vein cancerous thrombosis (PVCT).18 patients with HCC complicated with PVCT and esophageal or gastrio-fundal varices who underwent PTSVE were collected. The rate of success, complication, mortality of the procedure and postoperative complication were recorded and analyzed.PTSVE were successfully performed in 16 of 18 cases, and the rate of success was 89%. After therapy erythrocyte counts decreased in all of the natunts. 5 of patients needed blood transfusion, 2 patients required surgical intervention because of and 11 patients with ascites were alleviated by diuresis. Among these 18 patients, the procedure-related mortality was 11% (2/18), one died of acute hepatic failure on the forth day after procedure, another died of acute renal failure on the fifth day. The patients were follow up for 1-12 mon exceptone. 13 of them died of their tumors but none of them experienced variceal bleeding.PTSVE is a relatively safe and effective method to treat esophageal or gastrio-fundal varices in HCC patients with PVCT when percutaneous transhepatic varices embolization (PTHVE) of varices is impossible.
