| 1 | The value and limitation of transcatheter arterial chemoembolization in preventing recurrence of resected hepatocellular carcinoma显示文摘AIM: To evaluate the value and limitation of postoperative transcatheter arterial chemoembolization (TACE) in preventing recurrence of hepatocellular carcinoma (HCC). METHODS: In the first group, 987 postoperative patients with HCC, who did not have any evidence of recurrence in the first preventative TACE but were found to have recurrence at different times during the follow-up survey, were analyzed. In the second group, 643 postoperative patients with HCC had no TACE for compared study. To study the relationship between the recurrence time and the number of TACE treatments was analyzed. RESULTS: The 6-, 12-, and 18-mo recurrence rates in the first and second groups were 22.2% (210 cases) vs 61.6% (396 cases), 78.0% (770 cases) vs74.7% (480 cases) and 88.6% (874 cases) vs80.1% (515 cases). There were significant differences between the recurrence rates of the two groups at 6 mo (P<0.0001).CONCLUSION: The principal role of TACE after HCC operation is to suppress, detect early and treat micrometastasis. It has a good effect of preventing recurrence of HCC in 6 mo, but such an effect is less satisfactory in a longer period. When it is uncertain whether HCC is singlecentral or multi-central and if there is cancer residue or metastasis after operation, TACE is valuable to prevent recurrence. | Hong-YanCheng XiangWang DongChen Ai-MinXu Yu-ChenJia | 2005 | World Journal of Gastroenterology2005，11，23： | 38 |
| 2 | Contrast-enhanced ultrasonographic imaging diagnosis on assessment of vascularity in liver metastatic lesions显示文摘AIM: To investigate the vasculature of rabbit liver metastatic lesions by color Doppler imaging and power Doppler imaging (PDI) techniques.METHODS: Eight New Zealand rabbits with implanted VX2 liver tumors were used. All ultrasound examinations were performed with a HP 5500 color Doppler ultrasound scanner. Before and after the injection of contrast agent, the changes of gray scale and the periphery and intralesional blood flow of the liver metastatic lesion were carefully observed by B mode ultrasound, color Doppler flow imaging (CDFI)and PDI.RESULTS: Twelve lesions were found in the eight rabbits with implanted VX2 liver tumors, whose diameter rangedfrom 1.6 to 4.8 cm. Echoes of these lesions were not characterized and has lack of specificity. After the injectionof contrast agent, the numbers of dot or strip-like flow messages increased both at the periphery and inside of these lesions under the mode of CDFI and PDI, and were more pronounced under PDI. Morphology of intralesional vessels extended, even branched and some signals were clearly found encircling the lesion. And some vessels were found penetrating into the center of the lesion.CONCLUSION: PDI after injection of self-made echo contrast agent can show a pronounced sensitivity than that of B mode ultrasound and CDFI in diagnosis of vascularity of a metastatic lesion. | Wen-HuaDu Wei-XiaoYang Xiu-QinXiong XiangWang YiZhou HuiWang | 2005 | World Journal of Gastroenterology2005，11，23： | 9 |
| 3 | Adjustment of lipiodol dose according to tumor blood supply during transcatheter arterial chemoembolization for large hepatocellular carcinoma by multidetector helical CT显示文摘AIM: To work out an indMdualized lipiodol dose in transcabheter arterial chemoembolization (TACE) for large hepatocellular carcinoma (HCC) according to its blood supply evaluated by CT.METHODS: One hundred patients with large HCC (more than 8 cm in diameter) were studied by multidetector helical CT. Patterns of blood supply of HCC were divided into sufficient blood supply, poor blood supply, mixed blood supply and arteriovenous (A-V) shunt. The dose of ultrafluid lipiodol was determined by diameter and blood supply type of HCC. Patients were divided into two groups (50 cases each): lipiodol perfusion group and iodized oil perfusion group according to tumor diameter and the blood supply type of tumor.RESULTS: The confirmation and effective rates were 82%,84% in the first group and 36%, 46% in the second group (P<0.01).CONCLUSION: A relatively individualized lipiodol dose may be determined according to the blood supply pattern and the tumor diameter by CT imaging. | Hong-YanCheng YiShou XiangWang Ai-MinXu DongChen Yu-ChenJia | 2004 | World Journal of Gastroenterology2004，10，18： | 8 |

| 15 | New Superconvergent Structures with Optional Superconvergent Points for the Finite Volume Element Method显示文摘New superconvergent structures are proposed and analyzed for the finite volume element(FVE)method over tensorial meshes in general dimension d(for d≥2);we call these orthogonal superconvergent structures.In this framework,one has the freedom to choose the superconvergent points of tensorial k-order FVE schemes(for k≥3).This flexibility contrasts with the superconvergent points(such as Gauss points and Lobatto points)for current FE schemes and FVE schemes,which are fixed.The orthogonality condition and the modified M-decomposition(MMD)technique that are developed over tensorial meshes help in the construction of proper superclose functions for the FVE solutions and in ensuring the new superconvergence properties of the FVE schemes.Numerical experiments are provided to validate our theoretical results. | XiangWang Yuqing Zhang Zhimin Zhang | 2023 | Communications in Computational Physics2023，33，5： | 0 |
| 16 | The Mid-Long Term Outcome of Breast-Conserving Patients with Different Ages显示文摘OBJECTIVE Breast-conserving surgery has been a standardtreatment for relatively small size of breast cancer.Younger breastcancer patients have more desire to conserve their breasts.Thisstudy was to investigate the clinicopathological characteristics andprognosis of younger breast cancer patients who received breast-conserving treatment in China.METHODS The data of 232 breast cancer patients who receivedbreast-conserving treatment in Cancer Hospital of ChineseAcademy of Medical Science from January 1^(st),1999 to December31^(st),2005,were collected and retrospectively analyzed.Accordingto the age,the patients were divided into 2 groups:younger group(age≤35 at the time of diagnosis)and elder group(age>35).Theclinical features of the patients in the 2 groups were compared,and their clinical characteristics,recurrence,metastasis andsurvival status were summarized.RESULTS In the 232 cases,younger patients accounted for 15.9%(37/232),the elder 84.1%(195/232).By December 2008,the mediantime of follow-up was 54 months(ranging from 2 months to 118months).Two patients(5.41%,2/37)in the younger group and 5patients(2.56%,5/195)in the elder group died.The 5-year overallsurvival rate(OS)in the younger and elder groups was 96.08% and97.19%,respectively(x^2=0.69,P=0.4066).Local recurrence(LR)ordistant metastasis(DM)presented in 5 patients(5/37,13.51%)inyounger group.LR or DM presented in 10 patients(10/195,5.13%)in elder group.The 5-year disease-free survival(DFS)rate in theyounger and elder groups was 82.58% and 95.52%,respectively(x^2=4.02,P=0.0451).Lymph node status and the age of 35 years oldor younger were the prognosis factors affecting the DFS of patientswho received breast-conserving treatment(OR=3.467,95%CI:1.048-11.472,P<0.05;OR=0.245,95%CI:0.069-0.863,P<0.05).Lymph node status was the only prognostic factor affecting theDFS of younger group patients(OR=7.357,95%CI:1.030-52.563,P<0.05).CONCLUSION Though the younger and elder patients havethe same mid-long term survival rate,younger patients are morelikely to have recurrence or metastasis than the elder patients.Breast-conserving surgery given to the younger patients especiallyto the younger patients with lymph nodes positive should becontemplated cautiously. | Huiming Zhang XiangWang Baoning Zhang | 2009 | Clinical oncology and cancer resexreh2009，6，4： | 0 |
