Objective To compare the short-term clinical outcomes of hand-assisted laparoscopic surgery(HALS),laparoscopic-assisted surgery (LAS)and open surgery(OS)for colorectal cancer treatment. Methods The clinical data of 74 patients underwent HALS,LAS and OS for colorectal cancer treatment between October 2011 and December 2015 were assessed retrospectively. All the surgeries were performed by the same surgical team. The intraoperative details,postoperative recovery,postoperative complications,oncologic results and cost were compared among the three groups. Results A total of 24 patients in HALS group,25 patients in LAS group and 25 patients in OS group were finally included. The gen-eral data and oncologic baseline were comparable among the three groups. The comparative results showed that the operative time increase d and in-cision length shortened gradually in OS group,HALS group and LAS group(P<0.05). HALS group was favor of less number of trocars used com-pared with LAS group(P<0.05),but there was no statistical difference of the conversion rate between the two groups(P>0.05). In terms of post-operative recovery,postoperative complications and oncologic results,there was no statistical difference between the three groups(P>0.05). As for cost,the total cost and operative cost of OS group were lower than HALS group and LAS group(P<0.05),but there was no significant differ-ence between HALS group and LAS group(P>0.05). The material cost increase gradually in OS group ,HALS group and LAS group(P<0.05), and there was no significant difference on the part of other cost among the three groups(P>0.05). Conclusion HALS,LAS and OS are compen-satory with each other,and clinicians can choose the reasonable procedure according to personal proficiency and situation of patients.

Objective To investigate the incidence of postoperative hepatic metastasis,clinicolpathological characteristics and the prognosis for pancreatic cancer. Methods Totally 83 cases with pancreatic cancer admitted in our hospital during January 2007 to September 2012 was retro?spectively analyzed according to clinicolpathological data. Results Postoperative liver metastasis occurred in 31 cases with a metastatic rate of 37.3%. The size(χ2=9.606;P=0.002),vascular invasion(χ2=4.794,P=0.029)and UICC stage(χ2=5.318,P=0.021)were correlated with he?patic metastasis. Univariate analysis revealed the poor prognosis in pancreatic cancer patient with hepatic metastasis(χ2=9.967,P=0.002). Cox re?gression analysis revealed hepatic metastasis as an independent prognostic factor(P=0.001). Conclusion Pancreatic cancer has a high possibility of hepatic metastasis. Postoperative hepatic metastasis was one of the independent factors for the prognosis of pancreatic cancer. Tumor size,vascular invasion and UICC stages were risk factors for postoperative liver metastasis of pancreatic cancer.

Background and purpose:Metastatic colorectal cancer (mCRC) patients with K-ras mutation won’t benefit in the anti-epidermal growth factor receptor (EGFR) treatments. Thus K-ras mutation analysis is mandatory before this treatment. There is controversy that K-ras mutation analysis should be performed on primaries or related metastases. The aim of our study was to evaluate the concordance of K-ras status between primary and related metastases tumors, thus investigate the validity and rigorousness of clinical K-ras testing. Methods:Seventy-six patients with confirmed mCRC treated in Fudan University Shanghai Cancer Center were enrolled. After DNA extraction and PCR amplification, tumor specimens with paired primary tumors and related metastatic sites were put into sequencing analysis. And the K-ras mutation status in exon 2 was assessed. Results: K-ras mutation was detected in 31 out of 76 primary tumours (40.8%) and also 40.8%of the metastatic sites. But discordance was found between primary tumor and metastasis in 15 cases (19.7%):8 primary tumors had a K-ras mutation with a wild-type metastasis, meanwhile 7 primary tumors were wild type with a K-ras-mutated metastasis. Conclusion:Our study indicated that quite a few mCRC cases have different K-ras status between primary tumors and related metastatic sites, and it’s not very rigorous to choose the anti-EGFR treatments merely according to the primary tumor-K-ras mutation.Further study and consultation are needed on this problem.

Objective To assess retinal arteriole stenosis in cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) and to evaluate the relationship between retinal arteriole stenosis with cranial MRI changes and clinical features. Methods Sixteen CADASIL patients (mean age was (43.4±8.1)years, mean duration was(4.7±3.4)years)and sixteen age matched healthy individuals were enrolled. Mini-Mental State Examination (MMSE) and modified Rankin scale scoring were performed in 16 patients. Cranial MRl with Coulthard scores was assessed on CADASIL patients as well. Retinal examinations for arteriole stenosis were done for each subject. Bivariate correlations (Kendall's tau-b) were used to assess the relationship among the grade of retinal stenosis, MMSE, modified Rankin seale, cranial MRI with Coulthard scores and age. Results Retinal arteriole stenosis presented in 15 cases. in whom 4 cases showed mild arterio-venous nicking. while it only presented in 2 controls. Grade 0.Ⅰ, and Ⅲ of retinal arteriole stenosis are noted in 1/16,4/16,7/16 and 4/16cases respectively. Coulthard scores of cerebral MRl were 6.0.19.0.25.1 and 29.8 respectively from Grade 0 toⅢ of retinal arteriole stenosis. The correlation coefficient of retinal arteriole stenosis and cranial MRI scores was 0.743(P<0.001=,MMSE-0.429(P<0.05=,modified Rankin scale 0.437(P>0.05).and age 0.299(P>0.05).Conclusion Retinal arteriole stenosis is significantly correlated with lesion in cranial MRI and dementia.

Objective To investigate the feasibility, safety and efficacy of transarterial embolization with low concentration of n-butyl cyanoacrylate(NBCA) in rabbit VX2 liver tumor models. MethodsTwenty-four rabbits were implanted with VX2 hepatic tumors into the left hepatic lobes, and were scanned with CT to measure the volume of the tumor after 14 days. They were randomly divided into three groups with 8 rabbits assigned to each group. Transarterial embolization was conducted with physiological saline in control group A, with pure Lipiodol in group B, with 2.5% NBCA in group C. Hepatic toxicity was evaluated by blood biochemical analysis of the plasma alanine aminotransferase (ALT) and aspartate aminotransferase (AST). One week later, the volumes of the tumors were measured by CT again. Tumor growth rate was the ratio of tumor's volume at 7th day after embolization to the tumors' volume before embolization. The survival periods of the rabbits of the three groups after treatment were also recorded. The data of ALT and AST mean values from each group were analyzed with repeated measurement analysis of variance (ANOVA). Tumor growth rates and survival periods were analyzed by using one-way ANOVA. Results All animal models were successfully established and underwent interventional catheterization. Both ALT and AST mean values of the rabbits in group A, B and C at each time point before and after embolization were significantly different (ALT F=10.508, 16.443, 19.828, respectively; AST F=23.696, 23.334, 15.594, respectively)(P<0.05). ALT in group A, B, C were (49.4±13.5), (115.2±48.8), (124.7±49.4)U/L, while AST in group A, B, C were (52.3±12.0), (128.3±50.1), (137.0±66.9)U/L 4 days after embolization. The ALT and AST mean values were significantly elevated 4 days after embolization in group B and group C compared with those before embolization and those of group A 4 days after treatment(P<0.05). However, the ALT and AST mean values showed no statistically significant difference in all the groups before embolization and 7 days after embolization. On the other hand, the growth rates of the tumors differed significantly among the three groups(F=110.865, P=0.000). The group C showed significantly lower tumor growth rate (0.839±0.144)% than the group A(2.978±0.547)%(P=0.000), but no significantly different tumor growth rate compared with group B(0.871±0.0725)%( P=0.845). Consequently, the survival period of the animals in group C(38.9±4.0) days was significantly longer than that in group A(32.1±3.1)days (P=0.006), while it was not significantly different from that in group B(36.9±4.8)days(P=0.366). ConclusionsTransarterial embolization with low concentration of NBCA was feasible and safe. It could be a new option of treatment for HCC and might have potential further clinical value.
