Free PSA levels were significantly higher in women with breast cancer than that in healthy women (P<0.05). The percentage of free PSA predominant subjects was 37.6% in breast cancer patients and 3.3% in healthy women. Cut-off values were 0.36 ng/ml for total PSA and 0.02 ng/ml for free PSA. In women with breast cancer, total PSA positivity was 23.5% and free PSA positivity was 27.1%. Compared to negatives, total PSA positive patients had a higher percentage of lymph node involvement tumours (P>0.05). However, patients with predominant free PSA had a higher percentage of early stage than patients with predominant PSA-ACT.Conclusion: Although the sensitivity of free PSA predominance is low (37.6%) in distinguishing women with breast cancer from healthy women, its specificity is high (97.0%).Free PSA predominance tends to be present in early stage tumours. These findings may indicate clinical significance of preoperative measurement of serum total and free PSA in women with breast cancer.展开更多

Methods A total of 430 female in-patients with breast cancer of stages 0 to IIIC who came to Tianjin Medical University Cancer Institute and Hospital from January 2003 to January 2004 were studied and followed up until May 2011. Serum levels of biochemical markers for tumor and liver were measured at the time of diagnosis. Results Liver metastasis was more likely to occur in patients with stage Ill cancer or c-erbB-2-positive expression. Alanine aminotransferase, aspartate aminotransferase, ~/-glutamyltransferase (GGT), alkaline phosphatase, lactate dehvdrogenase (LDH), and carbohydrate antigen 1153 (CA153) levels were significantly higher in patients with liver metastasis than those without liver metastasis. Diagnostic indices of LDH, GGT, and CA153 were 174 U/L, 32 U/L, and 26.48 Dg/L, respectively. The areas under the curves of LDH, GGT, and CEA were 0.795, 0.784, and 0.661, respectively, and sensitivities of parallel tests for LDH and CA153 and for GGT and CA153 were 88.6% and 85.7 %, respectively. The specificity of serial tests for both pairs of enzymes was 97.7%. Conclusions Tile sensitivity and specificity of combined tumor and biochemical markers could be used as indicators during screening for breast-liver metastasis.展开更多

Methods: Conducted dynamic contrast-enhanced MRI and drew the time signal curves of breast lesions in 60 patients with breast disease (malignant 46, benign 14). Results: Morphological features of malignant tumors mostly showed blurred or thin spiculate outlines, irregular shape or Iobular signs, signal heterogeneity or peripheral enhancement in dynamic contrast-enhanced MRI. Time signal curve showed type III or II. Morphologic features of benign tumors mostly showed clear edge, regular shape and homogeneous signal, or diffuse spot enhancement. Time signal curve showed type I or II. Conclusion: breast dynamic contrast enhanced scan in MRI can provide morphology and functional diagnosis information of the breast tissues. Dynamic contrast-enhanced MRI combined with time signal curve can further improve the accuracy of diagnosis of early breast cancer.展开更多

Methods Mammography and DCE-MRI were performed for 120 patients with breast cancer(malignant, 102; benign; 18). Results The sensitivity of mammography for early diagnosis of breast cancer was 66.67%, specificity was 77.78%, and accuracy was 68.33%. The sensitivity of MRI for early diagnosis of breast cancer was 94.12%, specificity was 88.89%, and accuracy was 93.33%. However, the sensitivity of mammography combined with DCE-MRI volume imaging with enhanced water signal(VIEWS) scanning for early diagnosis of breast cancer was 97.06%, specificity was 94.44%, and accuracy was 96.67%. Conclusion Mammography combined with DCE-MRI increased the sensitivity, specificity, and accuracy of diagnosing early breast cancer.展开更多

In this case report, we retrospectively analyzed the imaging findings of three cases of non-HCC with macroscopic BDTT on dynamic enhanced multislice computed tomography (MSCT) scan. One case of primary hepatic carcinosarcoma was presented as a solitary, large welldefined tumor with significant necrotic changes. One case of liver metastasis from colon cancer was presented as a Iobulated, large ill-defined tumor. One case of intraductal oncocytic papillary neoplasm involved the entire pancreas, presented as a cystic and solid mass with multilocular changes (the individual Ioculi were less than 5.0 mm in diameter). The bile duct was dilated due to expansible growth of the BDFE in all three patients. The BDTT was contiguous with hepatic or pancreatictumor, and both of them showed the same enhancement patterns on dynamic contrast-enhanced computed tomography scan: early enhancement in the hepatic arterial phase and a quick wash out of contrast agent in the portal and equilibrium phases. Macroscopic BDTT- in non-HCC patient is rare, dynamic enhanced MSCT scan may be valuable in the diagnosis of non-HCC with BDTT.展开更多

The purpose of this study was to investigate whether sentinel lymph node biopsy (SLNB) should be performed in patients with an initial diagnosis of DCIS. Methods: A retrospective study was performed of 124 patients with an initial diagnosis of DCIS between March 2000 and June 2014. The patients were treated with either SLNB or axillary node dissection during the surgery, and we compared the clinicopathologic characteristics, image features, and immunohistochemical results. Results: Eighty-two patients (66.1%) had pure DCIS and 25 (20.2%) had DCIS with microinvasion (DCISM), 17 (13.7%) updated to invasive breast cancer (IBC). 115 patients (92.7%) underwent SLNB, among them, 70 patients (56.5%) underwent axillary node dissection. 3 of 115 patients (2.6%) had a positive sentinel lymph node, only 1 (1.4%) of 70 patients had axillary lymph node metastasis, in 84 patients (66.7%) who were diagnosed DCIS by core needle biopsy (CNB) and vacuum-assisted biopsy (VAB). 26 patients (31.0%) were upstaged into IBC or DCISM in the final histological diagnosis. The statistically significant factors predictive of underestimation were large tumor size, microcalcifications, comedo necrosis, positive Her-2 status, negative estrogen receptor status. Conclusion: The metastasis of sentinel lymph nodes in pure DCIS is very low, but the underestimation of invasive carcinoma in patients with an initial diagnosis of DCIS is an usual incident, especially in the cases when DCIS is diagnosed by CNB or VAB. Our findings suggest patients presenting with a preoperative diagnosis of DCIS associated with large tumor sizes, microcalcifications, comedo necrosis, positive Her-2 status, negative ER status are more likely to be DCISM and IBC in final diagnosis. SLNB should be performed in this part of patients.展开更多

RESULTS Among 29 cases,and with 79 galactophores examined,IDP was found in 11 cases (37.9% of the total cases),or 13.9% of the galactopores examined.IDP was found in 9 of 11 cases with a bloody nipple discharge,while IDP was seen in 2 of the 18 cases with a non-bloody nipple discharge.The excision accuracy achieved 100% in the cases,and postoperative pathological diagnosis accordance rate reached 88.9%. CONCLUSION Fiberoptic ductoscopy has many features such as ability to see the lesion,and accurate preoperative localization,thus eliminating excessive excision of tissue during surgery.For most patients with ND,especially those suffering galactostasis,OG or MDE,washout under fiberoptic ductoscopy and interventional therapy may achieve a thorough cure of the disease.展开更多

We report for the first time the simultaneous co-occurrence of these diseases in one patient. A 60-year-old woman was diagnosed with gastric diffuse large B-cell lymphoma (DLBCL) 2.5 years after she was found to have primary mucosa-associated lymphoid tissue (MALT) lymphoma of the breast. Although the patient underwent che-motherapy, she died of leukemia that caused irreversible cytopenia of three lineages. The data show that her MALT lymphoma apparently transfigured into gastric DLBCL. This case highlights the importance of evaluating patients for Helicobacter pylori infection when they present with extranodal MALT lymphomas, except gastric ones. Positive test findings should prompt anti-H, pylori therapy to prevent MALT lymphomas from transforming into DLBCLs.展开更多

Methods The search was conducted in the PubMed, Web of Science, Cochrane Library, and China Biology Medicine databases from inception through December 31, 2014, without language restrictions. The meta-analysis was conducted using STATA version 12.0 and Meta-Disc version 1.4. We calculated the summary statistics for sensitivity (Sen), specificity (Spe), positive and negative likelihood ratio (LR+/LR–), diagnostic odds ratio (DOR), and summary receiver operating characteristic (SROC) curve. Results Ten studies that met al inclusion criteria were included in the meta-analysis. A total of 608 ma-lignant breast lesions and 1292 benign breast tumors were assessed. Al breast lesions were histological y confirmed after RTE. The pooled Sen was 0.83 (95% CI = 0.79–0.86); the pooled Spe was 0.86 (95% CI = 0.84–0.88). The pooled LR+ was 9.87 (95% CI = 2.66–36.71); the pooled LR– was 0.20 (95% CI = 0.17–0.23). The pooled DOR of RTE for the diagnosis of breast cancer was 62.21 (95% CI = 33.88–114.24). The area under the SROC curve was 0.9334 (standard error = 0.00125). We found no evidence of publica-tion bias (t = –0.57, P = 0.582). Conclusion RTE may have high diagnostic accuracy for the dif erential diagnosis of benign and malig-nant breast tumors. RTE may be a good tool for breast cancer diagnosis.展开更多

Patients in whom this biopsy was diagnosed as carcinoma or a borderline lesion, had a subsequent surgical excision of the lesion. Histopathological and radiological features of the two specimens were then compared with each other. Results: Microcalcification was identified on specimen mammograms and microscopic slides in 97.4% of cases. Of 154 Mammotome biopsies 98 (63.6%) were benign, 51 (33.1%) were malignant, 3 (1.9%) showed atypical hyperplasia, and 2 (1.3%) were indeterminate, respectively. Of the 48 cases that received surgical excision, 6 of 36 ductal carcinomas in situ (16.7%) upstaged to invasive ductal carcinoma and 1 of 2 atypical ductal hyperplasias was upstaged to ductal carcinoma in situ. The positive predictive value of the 11-gauge Mammotome for the diagnosis of invasion in breast cancer was 100%. Linear calcification and pleomorphic calcification linear/segmental distribution was reliable indications of malignancy. The mean follow-up time of the benign lesions was 22 months, and without evidence of lesion growth. Complications included vasovagal reactions (6.3%), bleeding (0.6%) and hematoma (2.6%). Conclusion: The upright stereotactic 11-gauge Mammotome procedure is an effective and reliable method for the diagnosis of breast microcalcifications. It has minimal side effects. For lesions diagnosed as ADH or DCIS with the 11-gauge Mammotome, subsequent surgical excision should be performed.展开更多

Methods: From January 1990 to December 2005, 14 cases with breast cancer associated with pregnancy or lactation were analyzed retrospectively (TNM stage Ⅱ, 2 cases; stage Ⅲ, 11 cases; stage Ⅳ, 1 case). Diagnosis was established by fine needle aspiration biopsy primarily or routine pathological method if necessary. Abortion was used for discontinuation of pregnancy in 1 case with early pregnancy and 1 case with meddle pregnancy. 2 patients with late pregnancy received cesarean section, 10patients of breast cancer associated with lactation received multidisciplinary and-tumor treatment after discontinuation of lactation. Results: Diagnosis was confirmed by fine noodle aspiration biopsy in 9 cases and by secondary routine pathological method in the other 5 cases, 12 cases were followed up, 1 case of stage Ⅳ died of metastasis 5 months after diagnosis. 3-, 5-year survival rates in 10 cases of stage Ⅲ were 66% and 30% respectively. One case remained alive without recurrence for 8 years up to now. Conclusion: A thorough breast examination is necessary at the first antenatal visit physicians should aggressively pursue work-up in women with a palpable breast tass. In the patients during the second and third trimness, the various modalities available for treatment inholding abortion and their risks and beneath modalities available for treatment including abortion and their risks and benefits must be discussed openly with patients and their families.展开更多

METHODS: Coeliac disease (CD) patients were divided into two groups. Group Ⅰ : uncomplicated CD (n = 14) and RCD type Ⅰ (n = 10). Group Ⅱ : RCD type Ⅱ (n = 15) and EATL (n = 7). RESULTS: Both groups showed classic signs of CD on CT. Intussusception was seen in 1 patient in group Ⅰ vs 5 in group Ⅱ (P = 0.06). Lymphadenopathy was seen in 5 patients in group Ⅱ vs no patients in group Ⅰ (P = 0.01). Increased number of small mesenteric vessels was noted in 20 patients in group Ⅰ vs Ⅱ in group 11 (P = 0.02). Eleven patients (50%) in group 11 had a splenic volume 〈 122 cm^3 vs 4 in group Ⅰ (14%), 10 patients in group Ⅰ had a splenic volume 〉 196 cm^3 (66.7%) vs 5 in group Ⅱ (33.3%) P = 0.028. CONCLUSION: CT scan is a useful tool in discriminating between CD and (Pre) EATL. RCD Ⅱ and EATL showed more bowel wall thickening, lymphadenopathy and intussusception, less increase in number of small mesenteric vessels and a smaller splenic volume compared with CD and RCD Ⅰ.展开更多

The recent invention of the carbon nanotube (CNT) X-ray source technology holds great promise to revolutionize the field of biomedical X-ray imaging. CNT X-ray sources have been successfully adapted to several biomedical imaging applications including dynamic rnicro-CT of small animals and stationary breast tomosynthesis of breast cancers. Yet their more irnportant biomedical imaging applications still lie ahead in the future, with the devel- oprnent of stationary rnulti-source CT as a noteworthy exarnple.展开更多
文摘Objective: To investigate the diagnostic value and the relationship between the clinicopathological features and the levels of total and free prostate-specific antigen (PSA) in women with breast cancer.Methods: Using the microparticle enzyme immunoassay system, we measured the concentrations of these markers in the sera of 85 women with breast cancer and in 30 healthy women.Rseults: The lowest detection level for both markers was 0.01 ng/ml. Free PSA levels were significantly higher in women with breast cancer than that in healthy women (P<0.05). The percentage of free PSA predominant subjects was 37.6% in breast cancer patients and 3.3% in healthy women. Cut-off values were 0.36 ng/ml for total PSA and 0.02 ng/ml for free PSA. In women with breast cancer, total PSA positivity was 23.5% and free PSA positivity was 27.1%. Compared to negatives, total PSA positive patients had a higher percentage of lymph node involvement tumours (P>0.05). However, patients with predominant free PSA had a higher percentage of early stage than patients with predominant PSA-ACT.Conclusion: Although the sensitivity of free PSA predominance is low (37.6%) in distinguishing women with breast cancer from healthy women, its specificity is high (97.0%).Free PSA predominance tends to be present in early stage tumours. These findings may indicate clinical significance of preoperative measurement of serum total and free PSA in women with breast cancer.

文摘Objective To diagnose and explore the serological diagnostic factors for liver metastasis in patients with breast cancer before symptoms occur. Methods A total of 430 female in-patients with breast cancer of stages 0 to IIIC who came to Tianjin Medical University Cancer Institute and Hospital from January 2003 to January 2004 were studied and followed up until May 2011. Serum levels of biochemical markers for tumor and liver were measured at the time of diagnosis. Results Liver metastasis was more likely to occur in patients with stage Ill cancer or c-erbB-2-positive expression. Alanine aminotransferase, aspartate aminotransferase, ~/-glutamyltransferase (GGT), alkaline phosphatase, lactate dehvdrogenase (LDH), and carbohydrate antigen 1153 (CA153) levels were significantly higher in patients with liver metastasis than those without liver metastasis. Diagnostic indices of LDH, GGT, and CA153 were 174 U/L, 32 U/L, and 26.48 Dg/L, respectively. The areas under the curves of LDH, GGT, and CEA were 0.795, 0.784, and 0.661, respectively, and sensitivities of parallel tests for LDH and CA153 and for GGT and CA153 were 88.6% and 85.7 %, respectively. The specificity of serial tests for both pairs of enzymes was 97.7%. Conclusions Tile sensitivity and specificity of combined tumor and biochemical markers could be used as indicators during screening for breast-liver metastasis.

文摘We describe herein a 68-year-old woman who was diagnosed with a quite rare entity of intraductal papillary mucinous neoplasms(IPMNs) occurring simultaneously in the left lateral lobe of liver and the tail of pancreas.Abdominal computed tomography and magnetic resonance cholangiopancreatography showed a cystic dilatation of the pancreatic duct in the pancreatic tail,which suggested an IPMN,and multiple intrahepatic duct stones in the left lateral lobe.The patient underwent a laparoscopic left lateral hepatolobectomy and spleenpreserving distal pancreatectomy.Intra-operative finding of massive mucin in the dilated bile duct implied an intraductal mucinous tumor in the liver.The diagnosis of synchronous IPMNs in the liver and pancreas was confirmed by pathological examination.The patient was followed up for 6 mo without signs of recurrence.Although several cases of IPMN of liver without any pancreatic association have been reported,the simultaneous occurrence of IPMNs in the liver and pancreas is very rare.To the best of our knowledge,it is the first reported case treated by laparoscopic resection.
文摘Non-hepatocellular carcinoma (non-HCC) with macroscopic bile duct tumor thrombus (BDTI) formation is rare, few radiological studies have been reported. In this case report, we retrospectively analyzed the imaging findings of three cases of non-HCC with macroscopic BDTT on dynamic enhanced multislice computed tomography (MSCT) scan. One case of primary hepatic carcinosarcoma was presented as a solitary, large welldefined tumor with significant necrotic changes. One case of liver metastasis from colon cancer was presented as a Iobulated, large ill-defined tumor. One case of intraductal oncocytic papillary neoplasm involved the entire pancreas, presented as a cystic and solid mass with multilocular changes (the individual Ioculi were less than 5.0 mm in diameter). The bile duct was dilated due to expansible growth of the BDFE in all three patients. The BDTT was contiguous with hepatic or pancreatictumor, and both of them showed the same enhancement patterns on dynamic contrast-enhanced computed tomography scan: early enhancement in the hepatic arterial phase and a quick wash out of contrast agent in the portal and equilibrium phases. Macroscopic BDTT- in non-HCC patient is rare, dynamic enhanced MSCT scan may be valuable in the diagnosis of non-HCC with BDTT.
文摘Axillary lymph node status is one of the most important prognostic indicator of survival for breast cancer, especially in ductal carcinoma in situ (DCIS). The purpose of this study was to investigate whether sentinel lymph node biopsy (SLNB) should be performed in patients with an initial diagnosis of DCIS. Methods: A retrospective study was performed of 124 patients with an initial diagnosis of DCIS between March 2000 and June 2014. The patients were treated with either SLNB or axillary node dissection during the surgery, and we compared the clinicopathologic characteristics, image features, and immunohistochemical results. Results: Eighty-two patients (66.1%) had pure DCIS and 25 (20.2%) had DCIS with microinvasion (DCISM), 17 (13.7%) updated to invasive breast cancer (IBC). 115 patients (92.7%) underwent SLNB, among them, 70 patients (56.5%) underwent axillary node dissection. 3 of 115 patients (2.6%) had a positive sentinel lymph node, only 1 (1.4%) of 70 patients had axillary lymph node metastasis, in 84 patients (66.7%) who were diagnosed DCIS by core needle biopsy (CNB) and vacuum-assisted biopsy (VAB). 26 patients (31.0%) were upstaged into IBC or DCISM in the final histological diagnosis. The statistically significant factors predictive of underestimation were large tumor size, microcalcifications, comedo necrosis, positive Her-2 status, negative estrogen receptor status. Conclusion: The metastasis of sentinel lymph nodes in pure DCIS is very low, but the underestimation of invasive carcinoma in patients with an initial diagnosis of DCIS is an usual incident, especially in the cases when DCIS is diagnosed by CNB or VAB. Our findings suggest patients presenting with a preoperative diagnosis of DCIS associated with large tumor sizes, microcalcifications, comedo necrosis, positive Her-2 status, negative ER status are more likely to be DCISM and IBC in final diagnosis. SLNB should be performed in this part of patients.
文摘OBJECTIVE To explore the value of fiberoptic ductoscopy in diagnosing and treating bilateral and polyporous nipple discharge (ND).METHODS Fiberoptic ductoscopy was conducted in 29 patients with bilateral and polyporous ND.After the ductoscopy,the patients with intraductal papilloma (IDP) underwent a surgical procedure,and the others,identified with galactostasis,mammary duct ectasia (MDE) and obstructive galactophoritis (OG),received a ductoscopy-guided interventional therapy. RESULTS Among 29 cases,and with 79 galactophores examined,IDP was found in 11 cases (37.9% of the total cases),or 13.9% of the galactopores examined.IDP was found in 9 of 11 cases with a bloody nipple discharge,while IDP was seen in 2 of the 18 cases with a non-bloody nipple discharge.The excision accuracy achieved 100% in the cases,and postoperative pathological diagnosis accordance rate reached 88.9%. CONCLUSION Fiberoptic ductoscopy has many features such as ability to see the lesion,and accurate preoperative localization,thus eliminating excessive excision of tissue during surgery.For most patients with ND,especially those suffering galactostasis,OG or MDE,washout under fiberoptic ductoscopy and interventional therapy may achieve a thorough cure of the disease.
文摘Objective:The aim of this study was evaluate the diagnostic value of computed tomography(CT) perfusion in breast cancer by the method of receiver operator characteristic curve(ROC) analysis.Methods:Eighty-one cases with breast masses found by health examination or mammography were scanned by multi-slice spiral CT(MSCT) perfusion and hemodynamic parameters of blood flow(BF), mean transit time(MTT) and blood volume(BV) were calculated by deconvolution arithmetic.According to the pathologic results, two groups, benign and malignant were classified and statistical analysis were performed between them.The ROC characteristics of BF, MTT, BV were compared for each and the diagnostic value of the hemodynamic parameters were confirmed.Results:In the malignant group, BF was(0.735 ± 0.440) mL/min/mL, MTT was(22.771 ± 7.647) s and BV was 0.234 ± 0.082.In the benign group, BF was(0.466 ± 0.527) mL/min/mL, MTT was(26.712 ± 12.934) s and BV was 0.179 ± 0.117.There was a significant difference for BF and BV between the benign and malignant groups.When the hemodynamic parameters were used to discriminate the breast lesions, the area under the ROC curve(AUCROC) of BF was 0.832 ± 0.086, the maximum, while AUCROC of BV was 0.695 ± 0.092.There was no significant statistical difference between BF and BV.AUCROC of MTT was 0.473 ± 0.102, which was minimal.Since the threshold of BF was 0.381 mL/min/mL, the sensitivity was 82.3%, the specificity was 73.2%, the positive likelihood ratio(LR) was 3.071 and the negative LR was 0.242.The threshold of BV was 0.190 with sensitivity 73.3%, specificity 56.5%, positive likelihood ratio 1.685 and negative LR 0.473.Conclusion:BF and BV among CT hemodynamic parameters have certain diagnostic value in breast cancer, but BF or BV can not yet be single index to confirm or deny the diagnosis.
文摘Primary breast and gastric lymphomas as manifesta-tions of primary extranodal lymphomas are rare malignancies, and their diagnosis, prognosis, and treatment modalities remain unclear. We report for the first time the simultaneous co-occurrence of these diseases in one patient. A 60-year-old woman was diagnosed with gastric diffuse large B-cell lymphoma (DLBCL) 2.5 years after she was found to have primary mucosa-associated lymphoid tissue (MALT) lymphoma of the breast. Although the patient underwent che-motherapy, she died of leukemia that caused irreversible cytopenia of three lineages. The data show that her MALT lymphoma apparently transfigured into gastric DLBCL. This case highlights the importance of evaluating patients for Helicobacter pylori infection when they present with extranodal MALT lymphomas, except gastric ones. Positive test findings should prompt anti-H, pylori therapy to prevent MALT lymphomas from transforming into DLBCLs.
文摘Objective The present study aimed to determine the accuracy of real-time tissue elastography (RTE) for the diagnosis of breast cancer. Methods The search was conducted in the PubMed, Web of Science, Cochrane Library, and China Biology Medicine databases from inception through December 31, 2014, without language restrictions. The meta-analysis was conducted using STATA version 12.0 and Meta-Disc version 1.4. We calculated the summary statistics for sensitivity (Sen), specificity (Spe), positive and negative likelihood ratio (LR+/LR–), diagnostic odds ratio (DOR), and summary receiver operating characteristic (SROC) curve. Results Ten studies that met al inclusion criteria were included in the meta-analysis. A total of 608 ma-lignant breast lesions and 1292 benign breast tumors were assessed. Al breast lesions were histological y confirmed after RTE. The pooled Sen was 0.83 (95% CI = 0.79–0.86); the pooled Spe was 0.86 (95% CI = 0.84–0.88). The pooled LR+ was 9.87 (95% CI = 2.66–36.71); the pooled LR– was 0.20 (95% CI = 0.17–0.23). The pooled DOR of RTE for the diagnosis of breast cancer was 62.21 (95% CI = 33.88–114.24). The area under the SROC curve was 0.9334 (standard error = 0.00125). We found no evidence of publica-tion bias (t = –0.57, P = 0.582). Conclusion RTE may have high diagnostic accuracy for the dif erential diagnosis of benign and malig-nant breast tumors. RTE may be a good tool for breast cancer diagnosis.

文摘Objective: The aim of this study was to evaluate the utility of an upright-type 11-gauge stereotactic vacuumassisted biopsy device (Mammotome) for the diagnosis of breast microcalcifications Methods: Between May 2001 and October 2005, 154 biopsies in 152 patients with microcalcifications were performed using the upright-type 11-gauge stereotactic vacuum-assisted biopsy device. Patients in whom this biopsy was diagnosed as carcinoma or a borderline lesion, had a subsequent surgical excision of the lesion. Histopathological and radiological features of the two specimens were then compared with each other. Results: Microcalcification was identified on specimen mammograms and microscopic slides in 97.4% of cases. Of 154 Mammotome biopsies 98 (63.6%) were benign, 51 (33.1%) were malignant, 3 (1.9%) showed atypical hyperplasia, and 2 (1.3%) were indeterminate, respectively. Of the 48 cases that received surgical excision, 6 of 36 ductal carcinomas in situ (16.7%) upstaged to invasive ductal carcinoma and 1 of 2 atypical ductal hyperplasias was upstaged to ductal carcinoma in situ. The positive predictive value of the 11-gauge Mammotome for the diagnosis of invasion in breast cancer was 100%. Linear calcification and pleomorphic calcification linear/segmental distribution was reliable indications of malignancy. The mean follow-up time of the benign lesions was 22 months, and without evidence of lesion growth. Complications included vasovagal reactions (6.3%), bleeding (0.6%) and hematoma (2.6%). Conclusion: The upright stereotactic 11-gauge Mammotome procedure is an effective and reliable method for the diagnosis of breast microcalcifications. It has minimal side effects. For lesions diagnosed as ADH or DCIS with the 11-gauge Mammotome, subsequent surgical excision should be performed.
文摘Objective: To explore the diagnosis and treatment experience of breast cancer associated with pregnancy or lactation. Methods: From January 1990 to December 2005, 14 cases with breast cancer associated with pregnancy or lactation were analyzed retrospectively (TNM stage Ⅱ, 2 cases; stage Ⅲ, 11 cases; stage Ⅳ, 1 case). Diagnosis was established by fine needle aspiration biopsy primarily or routine pathological method if necessary. Abortion was used for discontinuation of pregnancy in 1 case with early pregnancy and 1 case with meddle pregnancy. 2 patients with late pregnancy received cesarean section, 10patients of breast cancer associated with lactation received multidisciplinary and-tumor treatment after discontinuation of lactation. Results: Diagnosis was confirmed by fine noodle aspiration biopsy in 9 cases and by secondary routine pathological method in the other 5 cases, 12 cases were followed up, 1 case of stage Ⅳ died of metastasis 5 months after diagnosis. 3-, 5-year survival rates in 10 cases of stage Ⅲ were 66% and 30% respectively. One case remained alive without recurrence for 8 years up to now. Conclusion: A thorough breast examination is necessary at the first antenatal visit physicians should aggressively pursue work-up in women with a palpable breast tass. In the patients during the second and third trimness, the various modalities available for treatment inholding abortion and their risks and beneath modalities available for treatment including abortion and their risks and benefits must be discussed openly with patients and their families.
文摘AIM: To evaluate computed tomography (CT) findings, useful to suggest the presence of refractory celiac disease (RCD) and enteropathy associated T cell lymphoma (EATL). METHODS: Coeliac disease (CD) patients were divided into two groups. Group Ⅰ : uncomplicated CD (n = 14) and RCD type Ⅰ (n = 10). Group Ⅱ : RCD type Ⅱ (n = 15) and EATL (n = 7). RESULTS: Both groups showed classic signs of CD on CT. Intussusception was seen in 1 patient in group Ⅰ vs 5 in group Ⅱ (P = 0.06). Lymphadenopathy was seen in 5 patients in group Ⅱ vs no patients in group Ⅰ (P = 0.01). Increased number of small mesenteric vessels was noted in 20 patients in group Ⅰ vs Ⅱ in group 11 (P = 0.02). Eleven patients (50%) in group 11 had a splenic volume 〈 122 cm^3 vs 4 in group Ⅰ (14%), 10 patients in group Ⅰ had a splenic volume 〉 196 cm^3 (66.7%) vs 5 in group Ⅱ (33.3%) P = 0.028. CONCLUSION: CT scan is a useful tool in discriminating between CD and (Pre) EATL. RCD Ⅱ and EATL showed more bowel wall thickening, lymphadenopathy and intussusception, less increase in number of small mesenteric vessels and a smaller splenic volume compared with CD and RCD Ⅰ.

文摘Although discovered more than 100 years ago, X-ray source technology has evolved rather slowly. The recent invention of the carbon nanotube (CNT) X-ray source technology holds great promise to revolutionize the field of biomedical X-ray imaging. CNT X-ray sources have been successfully adapted to several biomedical imaging applications including dynamic rnicro-CT of small animals and stationary breast tomosynthesis of breast cancers. Yet their more irnportant biomedical imaging applications still lie ahead in the future, with the devel- oprnent of stationary rnulti-source CT as a noteworthy exarnple.
