Objective To study the expression of c -Met protein in gastrointestinal stromal tumor(GIST) and to evaluate its clinicopathological significance.Methods The immunohistochemical technique,EnVision method was used to evaluate the expression of c -Met in 105 cases of GISTs.Results c -Met protein positive rate in GISTs was 9.52%(10 /105),its expression rate was significantly higher in GISTs with >10 /50HPF mitotic activity(P <0.05).c -Met protein expression rate was higher in GISTs which >5cm,moderate or high -risk,or mass located outside the stomach,but the difference was not statistically significant(P >0.05 ).Conclusion c -Met protein expression may related with risk of GISTs.We think that c -Met is worthy of further study for its potential usage as a evaluation indicators of GISTs clinicobiological behavior.

ObjectiveTo investigate the accuracy of automated breast volume scanning (ABVS) for the measurement of breast tumor size.MethodsSixty-two breast tumors in 59 patients were included in this study and were examined using conventional ultrasound and ABVS to measure the maximal diameters of the tumors. And the measurement results were compared with the pathological maximal diameters.Results There were 21 malignant and 41 benign tumors according to histopathological evaluation. There were no signifi cant differences between the maximal diameters on ABVS and on pathological measurements for both benign tumors and malignant tumors (Z=1.761, 0.262,P=0.078, 0.794). However, for malignant tumors, the maximal diameters on conventional ultrasound were significantly smaller than those on pathological measurements (Z=3.743,P=0.000). For benign tumors, the maximal diameters on conventional ultrasound were similar with those on pathological measurements (Z=1.935,P=0.053). The measurement values of conventional ultrasound and ABVS were both positively correlated with those on pathological values (r=0.935, 0.964,r=0.870, 0.964). And the correlation coeffi cients between ABVS and pathological measurement values were higher than those between conventional ultrasound and pathological measurement values for both benign and malignant tumors. ConclusionABVS can assess the size of breast tumor more accurately than conventional ultrasound, especially for the malignant tumors.

Objective: To study the clinicopathological features of breast invasive micropapillary carcinoma and its treatment and prognosis. Methods: Clinical data, radiological examination, histopathology, immunohistochemistry, therapeutic regimen and follow-up results of 16 cases of invasive micropapillary carcinoma of the breast were collected. The clinicopathological features, immunophenotype, imaging findings, treatment and prognosis were retrospectively analyzed. Results: All the 16 cases were female, with mean age of 56.3 years (40 to 89 years) . Of the 16 patients, 4 cases were pure invasive micropapillary carcinoma, and 12 cases were mixed invasive micropapillary carcinoma. Among the 12 cases of mixed invasive micropapillary carcinoma, 1 case was mixed with invasive ductal carcinoma, mucinous carcinoma and invasive micropapillary carcinoma, and the remaining 11 cases were all non-specific invasive ductal carcinoma with invasive micropapillary carcinoma. Out of the 16 cases, 13 (81.25%) were invasive micropapillary carcinoma with axillary lymph node metastasis, axillary lymph node metastasis which was more than 4 had 7 cases (43.75%) , clinical stage Ⅲ had 8 cases (50%) . According to the pathological results, 16 cases were treated with individualized comprehensive treatment. Of the 16 patients, 14 were followed up and 2 were lost. Conclusion Breast infiltrating micropapillary carcinoma is a rare type of breast cancer, with high rate of axillary lymph nodes metastasis, aggressive lymphatic invasiveness, high malignancy degree and poor prognosis.

OBJECTIVETo study the expression of fascin-1 protein in breast cancer and to evaluate its correlation with clinicopathologic features of the tumor.

METHODSImmunohistochemical EnVision method was performed to evaluate the expression of fascin-1 in 23 cases of normal breast tissues, 69 cases of benign breast lesions, 58 cases of usual ductal hyperplasia (UDH), 61 cases of ductal carcinoma in situ (DCIS) and 221 cases of breast cancer from March 2007 to December 2011.

RESULTSFascin-1 protein expression rates in normal breast tissues, benign breast lesions, UDH, DCIS and breast cancer were 100.0% (23/23), 89.9% (62/69), 13.8% (8/58), 19.7% (12/61), and 42.1% (93/221), respectively. Fascin-1 expression in normal breast tissues and benign breast lesions was significantly higher than those in UDH, DCIS and breast cancer (P < 0.01); Fascin-1 expression in breast cancer was significantly higher than those in UDH and DCIS (P < 0.01). There was a tendency of increased fascin-1 expression in DCIS compared to UDH, but the difference was not statistically significant (P > 0.05). Fascin-1 positive rates in patients with DCIS grade III (26.8%, 11/41) was significantly higher than that in patients with DCIS grade I-II (1/20, P < 0.05). Fascin-1 protein expression in breast cancer increased with increasing histologic grade and clinical stage (P < 0.01). Fascin-1 protein expression was also significantly higher in tumors with negative estrogen receptor (ER) and progestone receptor (PR) status and > 3 axillary lymph node metastases compared to tumors that were ER and PR positive and ≤ 3 axillary lymph node metastases (P < 0.01 and P < 0.05, respectively). Logistic regression analysis showed that fascin-1 expression correlated positively with high clinical stage (OR = 1.568, 95% CI = 1.029-2.387, P < 0.05) , but negatively with ER expression (OR = 0.149, 95% CI = 0.079-0.281, P < 0.01) .

CONCLUSIONSFascin-1 is highly expressed in normal breast tissues and benign breast lesions, suggesting that it may be a biological marker of mature mammary ductal epithelium. Fascin-1 protein expression shows a significantly increasing trend from UDH, DCIS to invasive breast cancer, suggesting that fascin-1 plays an important role in breast carcinogenesis and may be a potential target for therapy.

Cystic hypersecretory carcinoma of the breast is very rare, and has a special histological morphology and immunophenotype. It was understood that it cannot be misdiagnosed as invasive carcinoma of the breast or other benign lesions. This paper reports a case of this tumor treated in our hospital on Apr. 2, 2011. The clinical data, ultrasonic manifestations, histomorphology and immunophenotype were analyzed retrospectively. This study aims to investigate the clinicopathological, immunohistochemistry, diagnosis and prognosis of cystic hypersecretory carcinoma of the breast, so as to improve clinicians’further understanding of it.

Objective To comparatively observe the value of TIPS combined with catheter-directed thrombolysis and percutaneous transhepatic portal vein catheterization thrombolysis for acute non-cirrhotic non-neoplastic portal vein thrombosis(PVT).Methods Twenty-five patients with acute non-cirrhotic non-neoplastic PVT were retrospectively enrolled and clustered into TIPS group(n=17,underwent TIPS combined with catheter-directed thrombolysis)and liver puncture group(n=8,underwent percutaneous transhepatic portal vein catheterization thrombolysis)according to the access of thrombolysis.The technical success rate,duration of catheter-directed thrombolysis,complications within 7 days,as well as portal vein patency 3 months after treatment,Child-Pugh grading of liver function and occurrence of hepatic encephalopathy(HE)were recorded and compared between groups.Results The technical success rates were both 100%in 2 groups.There was no significant difference of the duration of catheter-directed thrombolysis between groups(P＞0.05).The thrombolytic effect in TIPS group was better than that in liver puncture group(P＜0.05).No significant difference of the occurrence of bleeding within 7 days was found between groups(P＞0.05).After 3 months'follow-up,the degree of portal vein patency in TIPS group was higher than that in liver puncture group(P＜0.05).No significant difference of Child-Pugh grading of liver function nor occurrence of HE was found between groups(both P＞0.05).Conclusion Both TIPS combined with catheter-directed thrombolysis and percutaneous transhepatic portal vein catheterization thrombolysis were effective for treating acute non-cirrhotic non-neoplastic PVT,and the thrombolytic effect of the former was better than the latter.
