OBJECTIVETo investigate the risk factors of metachronous bone metastasis after radical resection of colorectal cancer within 5 years.

METHODSClinical data of 1 749 patients with colorectal cancer, of whom 50(2.8%) patients developed metastasis to bone after operation, in the Department of Colorectal Surgery, Changhai Hospital of The Second Military Medical University from January 2001 to December 2010 were analyzed retrospectively. Univariate and multivariate analysis were performed to find the risk factors of metachronous bone metastasis from colorectal cancer using Chi square test and Logistic regression, respectively.

RESULTSOf 50 colorectal cancer cases with bone metastasis, 29 were male and 21 were female. The age was ≥ 60 years old in 28 cases. Tumors of 36 cases were located in the rectum and of 14 cases located in the colon. Pathology examination showed 43 cases were adenocarcinomas, 7 cases were mucinous adenocarcinoma. Forty-two cases had T3-4 stage lesions, 30 cases had lymph node metastasis, 14 cases had pulmonary metastasis, and 5 cases had liver metastasis. Univariate Chi square test indicated that factors associated with the metachronous bone metastasis of colorectal cancer within 5 years were tumor site (χ=4.932, P=0.026), preoperative carbohydrate antigen 199 (CA199) level (χ=4.266, P=0.039), lymph node metastasis (χ=13.054, P=0.000) and pulmonary metastasis(χ=35.524, P=0.000). The incidence of bone metastasis in patients with rectal cancer (3.6%, 36/991) was higher compared to those with colon cancer (1.8%, 14/758). The incidence of bone metastasis in patients with higher(> 37 kU/L) preoperative serum CA199 level (4.9%, 12/245) was higher compared to those with lower serum CA199 level (2.5%, 38/1504). The incidence of bone metastasis in patients with lymph node metastasis(4.8%,30/627) and pulmonary metastasis (11.6%, 14/121) was significantly higher compared to those without lymph node metastasis (1.8%, 20/1122) and pulmonary metastasis(2.2%, 36/1628), respectively. Logistic multivariate analysis showed that rectal cancer(OR:0.508, 95%CI:0.268 to 0.963, P=0.038), lymph node metastasis (OR:2.291, 95%CI:1.273 to 4.122, P=0.006) and metachronous pulmonary metastasis(OR:4.796, 95%CI:2.473 to 9.301, P=0.000) were the independent risk factors of metachronous bone metastasis of colorectal cancer within 5 years.

CONCLUSIONPatients with rectal cancer, lymph node metastasis and metachronous pulmonary metastasis are high risk groups of metachronous bone metastasis after radical resection of colorectal cancer within 5 years.

INTRODUCTIONThis study aimed to quantify and investigate factors affecting the health-related quality of life (HRQoL) in children with biliary atresia (BA) living with their native livers.

MATERIALS AND METHODSA cross-sectional study on the HRQoL using the PedsQL4.0 generic core scales in children with BA aged between 2 to 18 years followed up at the University Malaya Medical Centre (UMMC) in Malaysia was conducted. Two groups, consisting of healthy children and children with chronic liver disease (CLD) caused by other aetiologies, were recruited as controls.

RESULTSChildren with BA living with their native livers (n = 36; median (range) age: 7.4 (2 to 18) years; overall HRQoL score: 85.6) have a comparable HRQoL score with healthy children (n = 81; median age: 7.0 years; overall HQRoL score: 87.4; P = 0.504) as well as children with CLD (n = 44; median age: 4.3 years; overall score: 87.1; P = 0.563). The HRQoL of children with BA was not adversely affected by having 1 or more hospitalisations in the preceding 12 months, the presence of portal hypertension, older age at corrective surgery (>60 days), a lower level of serum albumin (≤34 g/L) or a higher blood international normalised ratio (INR) (≥1.2). Children who had liver transplantation for BA did not have a significantly better HRQoL as compared to those who had survived with their native livers (85.4 vs 85.7, P = 0.960).

CONCLUSIONHRQoL in children with BA living with their native livers is comparable to healthy children.

The function of the spleen in tumor development has been investigated for years. The relationship of the spleen with hepatocellular carcinoma (HCC), a huge health burden worldwide, however, remains unknown. The present study aimed to examine the effect of splenectomy on the development of HCC and the possible mechanism. Mouse hepatic carcinoma lines H22 and Hepa1-6 as well as BALB/c and C57 mice were used to establish orthotopic and metastatic mouse models of liver cancer. Mice were divided into four groups, including control group, splenectomy control group (S group), tumor group (T group) and tumor plus splenectomy group (T+S group). Tumor growth, metastases and overall survival were assessed at determined time points. Meanwhile, myeloid-derived suppressor cells (MDSCs) were isolated from the peripheral blood (PB), the spleen and liver tumors, and then measured by flow cytometery. It was found that liver cancer led to splenomegaly, and increased the percentage of MDSCs in the PB and spleen in the mouse models. Splenectomy inhibited the growth and progression of liver cancer and prolonged the overall survival time of orthotopic and metastatic models, which was accompanied by decreased proportion of MDSCs in the PB and tumors of liver cancer-bearing mouse. It was suggested that splenectomy could be considered an adjuvant therapy to treat liver cancer.

Currently, the most effective treatment for end-stage liver fibrosis is liver transplantation; however, transplantation is limited by a shortage of donor organs, surgical complications, immunological rejection, and high medical costs. Recently, mesenchymal stem cell (MSC) therapy has been suggested as an effective alternate approach for the treatment of hepatic diseases. MSCs have the potential to differentiate into hepatocytes, and therapeutic value exists in their immune-modulatory properties and secretion of trophic factors, such as growth factors and cytokines. In addition, MSCs can suppress inflammatory responses, reduce hepatocyte apoptosis, increase hepatocyte regeneration, regress liver fibrosis and enhance liver functionality. Despite these advantages, issues remain; MSCs also have fibrogenic potential and the capacity to promote tumor cell growth and oncogenicity. This paper summarizes the properties of MSCs for regenerative medicine and their therapeutic mechanisms and clinical application in the treatment of liver fibrosis. We also present several outstanding risks, including their fibrogenic potential and their capacity to promote pre-existing tumor cell growth and oncogenicity.

Based on their ability to differentiate into multiple cell types including hepatocytes, the transplantation of mesenchymal stem cells (MSCs) has been suggested as an effective therapy for chronic liver diseases. The aim of this study was to evaluate the safety, efficacy and therapeutic effects of MSCs in patients with chronic liver disease through a literature-based examination. We performed a systematic review (SR) and meta-analysis (MA) of the literature using the Ovid-MEDLINE, EMBASE and Cochrane Library databases (up to November 2014) to identify clinical studies in which patients with liver diseases were treated with MSC therapy. Of the 568 studies identified by the initial literature search, we analyzed 14 studies and 448 patients based on our selection criteria. None of the studies reported the occurrence of statistically significant adverse events, side effects or complications. The majority of the analyzed studies showed improvements in liver function, ascites and encephalopathy. In particular, an MA showed that MSC therapy improved the total bilirubin level, the serum albumin level and the Model for End-stage Liver Disease (MELD) score after MSC treatment. Based on these results, MSC transplantation is considered to be safe for the treatment of chronic liver disease. However, although MSCs are potential therapeutic agents that may improve liver function, in order to obtain meaningful insights into their clinical efficacy, further robust clinical studies must be conducted to evaluate the clinical outcomes, such as histological improvement, increased survival and reduced liver-related complications, in patients with chronic liver disease.

OBJECTIVETo study the clinical value of total hemihepatic vascular exclusion (THHVE) in liver resection for patients with hepatocellular carcinoma (HCC) and impaired liver function.

METHODSThe data of 70 patients who underwent liver resection for HCC with impaired liver function between January 2009 and October 2011 were analyzed retrospectively. THHVE was applied in 38 patients (THHVE group), Pringle maneuver in 25 patients (Pringle group) and no vascular occlusion in 7 patients. In the THHVE group, 36 patients were male, 2 were female, average age was (54 ± 9) years. And in Pringle group, 23 patients were male, 2 were female, average age was (53 ± 10) years. Total intraoperative blood loss, blood transfusion rate, clamping time, postoperative complication rate, postoperative hospital stay and postoperative liver function were compared between the THHVE and Pringle group.

RESULTSTotal blood loss ((317 ± 186) ml vs. (506 ± 274) ml, t = -3.025, P = 0.004) and transfusion rate (10.5% vs. 32.0%, χ(2) = 4.509, P = 0.034) were significantly lower in the THHVE group than in the Pringle group. Although the clamping time was longer ((21 ± 5) minutes vs. (17 ± 5) minutes, t = 3.209, P = 0.002), the total bilirubin levels on postoperative day 3 and 7 and ALT levels on postoperative day 1, 3, 7 were significantly lower in the THHVE group than in the Pringle group, and the pre-albumin level on postoperative day 7 was higher in the THHVE group than in the Pringle group. Total complication rate (26.3% vs. 52.0%, χ(2) = 4.291, P = 0.038) and major complication rate (7.9% vs. 28.0%, χ(2) = 4.565, P = 0.033) were lower in the THHVE group than in the Pringle group. And postoperative hospital stay duration was shorter in the THHVE group than in the Pringle group ((14.0 ± 2.6) d vs. (16.4 ± 4.0) d, t = -2.625, P = 0.012).

CONCLUSIONSTHHVE is a safe and effective technique in liver resection for patients with HCC and impaired liver function. It is associated with less blood loss, lower transfusion requirements, better postoperative liver function recovery, lower postoperative complication rate and shorter postoperative hospital stay.

Liver dysfunction by various reasons can cause metabolic disorders of a variety of nutrients and malnutrition, while malnutrition affects the recovery of liver function. Clinically patients undergoing gastrointestinal surgery are often accompanied with malnutrition, and these patients with liver dysfunction are easy to develop nutrient metabolic disorders. Therefore, improving the nutritional status of patients with liver dysfunction can improve the success rate of surgery and postoperative recovery. This article reviews the nutritional support in patients with liver dysfunction undergoing gastrointestinal surgery.

OBJECTIVE: To investigate the influence of endoscopic variceal ligation (EVL) on liver function and analyze the risk factors of rebleeding after EVL. METHODS: A total of 137 cirrhotic patients with esophageal varices who received EVL were retrospectively analyzed, and divided into group A, B, and C according to the Child-Pugh scores of liver function. We compared the liver function 1 week preoperatively and postoperatively. The patients were further divided into a rebleeding group and a non-rebleeding group after the EVL, and risk factors about rebleeding were analyzed. RESULTS: There was no significant difference on ALT, AST, T-Bil, and D-Bil either preoperatively or postoperatively in group A, B, and C (P>0.05). Thirteen patients (9.49%) rebled after the EVL. The course of disease, liver function, prothrombin time, and mass ascites were the risk factors of rebleeding. CONCLUSION EVL has no obvious effect on liver function, and the course of disease, liver function, prothrombin time and mass ascites are risk factors of rebleeding after EVL.

OBJECTIVETo compare the efficacies of portal vein stenting and transcatheter arterial chemoembolization (TACE) combined therapy performed with or without endovascular implantation of iodine-125 (125I) seeds strand in patients with hepatocellular carcinoma (HCC) and main portal vein tumor thrombus (MPVTT).

METHODSOne-hundred-and-six patients with HCC complicated by MPVTT who were treated with portal vein stents and TACE, either with (Group A, n=56) or without (Group B, n=50) endovascular implantation of 125I seeds strand, between July 2005 and April 2011, were retrospectively analyzed. Overall survival, stent patency, and procedure-related adverse events were compared between the two groups.

RESULTSThe technical success rate was 100% for placement of 125I seeds strands and stents in the obstructed main portal vein. No serious procedure-related adverse events were recorded. Group A had significantly higher median survival (335 days vs. group B: 146 days; P=0.001, hazard ratio (HR)=2.244). Additionally, group A had significantly higher median stent patency (400 days vs. group B: 190 days; P=0.005, HR=2.479).

CONCLUSIONThe combination therapeutic strategy of portal vein stenting and TACE with endovascular implantation of 125I seeds strands improves the survival of HCC patients with MPVTT complication.
