Objective:To assess the efficacy and safety of oncoplastic breast-conserving surgery (OBCS) in the treatment of early breast cancer. Methods:The clinicopathological data of breast cancer patients who were treated with OBCS (67 cases) and standard breast-conserving surgery (SBCS;117 cases) in Affiliated Cancer Hospital of Guangxi Medical University were retrospectively analyzed. Postop-erative complication, specimen weight, margins, and surgery re-excision rate between the two groups were compared. Results:Sero-ma (14.9%versus 48.7%, P<0.001), hematoma (4.5%versus 14.5%, P=0.035), and poor wound healing (3.0%versus 11.9%, P=0.036) were more common in the SBCS group than in the OBCS group. The patient satisfaction in the OBCS group was statistically higher than in the SBCS group (P<0.05). Compared with standard surgery, oncoplastic techniques can be employed for significantly larger tumors (25.04 mm versus 21.14 mm, P<0.001). OBCS resulted in higher mean specimen weights (92.24 g versus 57.44 g, P<0.001), wider clear nearest margins (12.04 mm versus 9.58 mm, P<0.001), and wider furthest margins (24.16 mm versus 15.24 mm, P<0.001). No statisti-cal increase was observed in further surgery re-excision of margins. Conclusion:OBCS is more successful than standard wide local exci-sion in treating larger tumors and obtaining wider radial margins. Oncoplastic approach showed no increase in postoperative complica-tion rate. The postoperative complication was excellent. OBCS is a safe and effective procedure for early breast cancer.

Objective To investigate expression and promoter methylation status of BRCA1 in sporadic breast cancer .Meth-ods The expression of BRCA1 mRNA and protein were detected in 60 cases of sporadic breast cancer ,the adjacent breast tissues , and 30 cases of breast benign lesion tissue by RT-PCR and and immunohistochemical staining respectively .The methylation status of BRCA1 promoter in those tissues were detected using bisulfite genomic sequencing PCR (BSP) combined with TA clone for se-quencing .The relation between BRCA1 expression in sporadic breast cancer and promoter methylation status was analyzed .Results The expression level of BRCA1 mRNA and protein were down-regulated in sporadic breast cancer tissues compared to the corre-sponding adjacent breast tissues and breast benign lesion tissue(P<0 .001) .The positive rates of BRCA1 protein was 51 .7% (31/60)in sporadic breast tissue ,which were significantly lower than those of in the adjacent breast tissues 71 .7% (43/60)and breast benign lesion tissue 66 .7% (20/30)(P< 0 .001) .The methylation rate of BRCA1 promoter CpG was 31 .7% (19/60)in sporadic breast ,while it wasn′t found in adjacent breast tissues and breast benign lesion tissue(P=0 .000) .The statistical analysis showed the expression of BRCA1 had significant negative correlation with promoter methylation(r= -0 .345 ,P=0 .007) .Conclusion The hypermethylation of BRCA1 promoter could induce BRCA1 down-regulating ,which may be involved in the occurrence and develop-ment of sporadic breast cancer .

Objective To measure hepatic blood flow of the normal liver and cirrhotic liver with hepatocellular carcinoma using multi-slice spiral CT(MSCT),and to evaluate the feasibility of the quantitative judgement of classification of liver cirrhosis with CT perfusion imaging.Methods CT dynamic perfusion imaging was performed in 53 subjects,including 32 patients of liver cirrhosis with hepatocellular carcinoma and 21 patients without liver disease(control subjects).The patients of liver cirrhosis with hepatocellular carcinoma were divided into three groups by CT morphologic classification :17 were classified as light liver cirrhosis group,8 as moderate group,7 as severe group.The parameters of CT perfusion included blood flow(BF),blood volume(BV),mean transit time(MTT),hepatic arterial fraction(HAF)and impulse residue function to(IRF To).The parameters were analyzed by the CT perfusion 3 software package(GE)with deconvolution method,and the correlation of the CT morphologic classification of liver cirrhosis with Child-Pugh functional classification was further evaluated.100 g-1,(17.81±6.59)ml/100 g,(9.52±3.08)s,0.20±0.08 and(4.38±2.35)s,respectively,while 0.27±0. 09 and (4. 14±2. 16)s, respectively. The mean BF, BV and HAF between normal livers and liver cirrhosis were statistically significant (P＜0. 05), and there were significant statistical differences in BF, BV and HAF among light, moderate and severe liver cirrhosis (P＜0. 05). The CT morphologic classification of liver cirrhosis was correlated positively with Child-Pugh classification (r=0. 935, P=0. 001 ). Conclusions Hepatic perfusion with MSCT can reflect the change of blood flow of cirrhotic liver, and MSCT perfusion can quantitatively evaluate the liver cirrhosis degree of patients with hepatocellular carcinoma.

Objective To study the applicable value of resection of segment VIII after cryotherapy for hepatocarcinoma. Methods As for 8 patients with hepatocarcinoma in segment VIII, the turnor was dealt with cryotherapy before resected. Results All the tumors were resected smoothly after cryotherapy with less bleeding (mean 430ml), less time (mean 138min) and without severe complications or postoperative death in this series. Conclusions Resection of segment VIII after cryotherapy for hepatocarcinoma is proved safe and feasible, whitch can decrease blood loss, save time, reduce tissue injury, and decrease postoperative recurrence.
Résumé
Objective To explore the effect of breast-conserving therapy for breast cancer(BCT) and its prognosis. Methods The clinical data of 69 cases of BCT admitted from January 1992 to December 2003 were analyzed retrospectively. The cases included those who had BCT without radiotherapy and those who had BCT with adjuvant radiotherapy, chemotherapy and hormonal therapy. The patients were followed up for 12 to 140 months. Results The 3-year recurrence rate for patients without radiotherapy (11.54%) was higher than that for those with radiotherapy (3.03%) (P
Résumé
Background and purpose:The prognosis in patients with early breast cancer(EBC) was poorly defined by clinical and histopathological features.There were more than 200 genes that might be correlated with development,progression,recurrence and prognosis of breast cancer in the published literature.This study evaluated the prognosis of patients with EBC at molecule level according to the protein expressions of 16 selecting genes(HER2,ER,PR,BCL2,Ki-67,BMYB,Cyclin B1,STK15,MMP11,BAG1,NM23,PTEN,P53,P27,VEGF,PCN A).Methods:The immunohistochemical method was used to detect the protein expressions of these genes in 76 patients with EBC and the statistical analysis was performed by COX proportional hazards model.Results:COX proportional hazard model revealed that BCL2,VEGF and STK15 were independent prognostic factors for patients with EBC.A formula of PI was set up according the three genes.The predictive outcomes with PI were compared with the actual follow-up outcomes in 48 patients with EBC.As a result,the predictive accuracy of good and bad prognosis was 86.67% and 91.67%,respectively.Conclusion:A formula of PI derived from protein expressions of the 16 genes correlated with breast cancer was ultimately set up and might be used to predict the outcomes of the patients with EBC.
