Methods From January 2003 to January 2009, 125 patients who were suspected to suffering from adrenal tumors underwent ultrasonography and CT examination. The results were then confirmed by surgery and pathology. There were 48 cases of pheochromocytoma, 41 adenoma, 11 adenocarcinoma, 9 metastatic tumor, 8 adrenal medullary lipoma, 2 nubblar hyperplasia, 4 tuberculosis of adrenal gland, 1 tumor of cauda pancreatic, 1 tumor of liver and 1 tumor of upper pole of kidney. Results The ultrasonographic features varied with different pathological types. The accuracy diagnosis of localizition and qualitation were 96.0% (120/125) and 91.2% (114/125) respectively. Conclusion Ultrasonography is useful in diagnosing tumors of adrenal gland, which may be used as the first choice for the disease.
Objective To establish the overall diagnostic accuracy of the measurements of vascular endothelial growth factor (VEGF) for malignant ascites. Methods After a systematic review of current studies, sensitivity, specificity, and other measures of the value of ascites concentrations of VEGF in the diagnosis of malignant ascites were pooled by using random effects models. Qualified studies on evaluation of VEGF in diagnosis of malignant ascites in English and Chinese published from January 1990 to December 2009 were retrieved from The Cochrane Library, Cochrane Central Register of Controlled Trials, MEDLINE, EMbase, China National Knowledge Infrastructure (CNKI) databases, WanFang Data, and VIP Information. Two reviewers independently assessed the methodological quality of each study with the tool of QUADAS. Statistical analyses were performed by employing Meta-Disc 1.4 software. Meta-analyses of the reported sensitivity and specificity of each study and Summary Receiver Operating Characteristic (SROC) curve were performed. Results Seven studies met the inclusion criteria for the analysis. After testing the heterogeneity of the included studies, a random effect model was selected to calculate the pool weighted sensitivity and specificity with 95% confidence interval: the sensitivity was 0.81 (95%CI 0.75 to 0.85), the specificity was 0.90 (95%CI 0.86 to 0.94), the DOR was 50.45 (95%CI 28.37 to 89.73), and the AUC of SROC was 0.9507 (SE=0.013 0). The subgroups were analyzed to identify the sources of heterogeneity according to race and agent sources. There was homogeneity among the three studies with agents from Ramp;D company (χ2=0.05, P=0.9750; I2=0.0%), and the AUC of SROC were 0.9675 (SE=0.016 7). Conclusion VEGF has a highly accurate sensitivity and specificity with a b ROC curve, which makes it a new marker to differentiate malignant ascites from the benign.
ObjectiveTo investigate the clinicopathological features, diagnosis and differential diagnosis of villoglandular carcinoma of the uterine cervix. MethodsThe clinical data of a 34-year-old patient diagnosed with villoglandular carcinoma of cervix on April 6, 2010 was retrospectively analyzed. Surgical excision samples were analyzed by means of hematoxylin-eosin and immunohistochemical staining. ResultsThe gross appearance of the tumor mass showed cauliflower-like pattern of growth. Histologically, it was similar to colorectal villoglandular adenoma, and was composed of branching papillae shaped like villous glandular tube structure, and the surface was coated with pseudostratified or stratified columnar cells which showed mild atypia and uncommon mitotic figures. Immunohistochemically, tumor cells were positive for carcinoma embryonic antigen, CK7 and CA125, and negative for estrogen receptor, progesterone receptor, P16, p53 and vimentin. This patient was subjected to a follow-up of 48 months, and was alive without recurrence or metastasis. ConclusionsVilloglandular carcinoma of the uterine cervix is rare and has a favorable prognosis. The diagnosis of villoglandular carcinoma depends on pathological morphology, and meanwhile, it is necessary to distinguish villoglandular carcinoma from other benign and malignant tumors which exhibited papillary growth pattern.
Objective To investigate clinical significance of serum VEGF-C level and C-erbB-2 protein expression in patients with breast cancer. Methods Sixty-two female patients with breast invasive ductal cancer and breast benign lesion were respectively selected. Serum VEGF-C level was detected by enzyme-linked immunosorbent assay (ELISA) before operation and at one month after operation, and C-erbB-2 protein expression in tissues of breast cancer was detected by immunohistochemistry. Then, the relationship between serum VEGF-C level and clinicopathologic characteristics and C-erbB-2 protein expressions wereas analyzed. Results The serum VEGF-C level before operation in breast cancer patients〔(279.65±17.34) pg/ml〕 was significantly higher than that in breast benign lesions patients 〔(167.26±12.15) pg/ml〕, P＜0.01. In breast cancer patients, the serum VEGF-C level before operation was higher than that at one month after operation 〔(209.45±15.23) pg/ml〕, P＜0.01. The serum VEGF level was related to tumor stage (P＜0.05) but not to patient age, tumor size, menopause status , lymph node metastasis or not and ER and PR expression (Pgt;0.05). The positive expression rate of C-erbB-2 protein in breast cancer patients (54.84%, 34/62) was significantly higher than that in breast benign lesion patients (11.29%, 7/62), P＜0.01. Moreover, the positive expression rate of C-erbB-2 protein in breast cancer patients with axilla lymph node metastasis (69.44%) was significantly higher than that without axilla lymph node metastases (34.62%), P＜0.05. The serum VEGF level increased with increasing expression intensity of C-erbB-2 protein and there was positive correlation between them (r=0.813，P＜0.05). Conclusions The serum VEGF-C level in breast cancer may be conducted as an assisted marker to differential diagnosis of breast tumor. C-erbB-2 is related to lymph node metastasis of breast cancer patients. There is synergistic effect between VEGF-C and C-erbB-2 in the lymph node metastasis way of breast cancer.
Objective To explore the value of three-dimensional contrast-enhanced ultrasound angiography in the differential diagnosis of breast masses. Methods A total of 120 patients with breast masses who were treated in our hospital from July 2013 to February 2016 were selected as the research objects retrospectively, including 70 patients of benign tumor (benign group) and 50 patients of malignant tumor (malignant group) that confirmed by surgery and pathology. All patients were given conventional two-dimensional ultrasound and three-dimensional contrast-enhanced ultrasound angiography during the diagnosis. Compared the imaging features of benign group and malignant group, and compared the diagnostic value of two-dimensional ultrasound and three-dimensional contrast-enhanced ultrasound angiography for breast masses. Results Compared with benign group, the rates of irregular masses, unclear boundary, inhomogeneous echo, lateral shadowing, echo attenuation, and micro calcification in the malignant group were all higher (P<0.05). The three-dimensional contrast-enhanced ultrasound angiography scores in malignant group and benign group were significantly different with each other (P<0.05), the score of the malignant group was higher than that of benign group. The 2- and 3-score was common in benign group, but 4- and 5-score was common in malignant group. The diagnostic sensitivity of two-dimensional ultrasound and three-dimensional contrast-enhanced ultrasound angiography for breast masses were 97.1% (68/70) and 98.6% (69/70) respectively, and the specificity were 80.0% (40/50) and 96.0% (48/50) respectively, the specificity of three-dimensional contrast-enhanced ultrasound angiography was significantly higher than that of two-dimensional ultrasound (P<0.05). Conclusion Two-dimensional ultrasound and three-dimensional contrast-enhanced ultrasound angiography both have a certain diagnostic value in the differential diagnosis of breast masses, but the three dimensional contrast-enhanced ultrasound angiography can get more information through assessment of richness of the microvascular in tumor tissue, so as to improve the diagnostic specificity and is worthy of popularization and application.
Hepatic angiomyolipoma (HAML) is a rare benign mesenchymal tumor of the liver, which has highly variable imaging appearances, often leads to missed diagnosis and misdiagnosis. The images of 2 patients with HAML confirmed by pathology were presented in this study, and the typical imaging features of the HAML, the underlying pathophysiological mechanism, and the differential diagnosis were briefly summarized so as to deepen the understanding of HAML and to improve the diagnosis and differential diagnosis abilities of HAML, then reduce the rates of missed diagnosis and misdiagnosis of the HAML.
