    Objective: To determine the frequencies of various benign breast diseases (BBD) in female patients in three private hospitals of Hyderabad. Methodology: This is a prospective cohort study of all female patients visiting the surgical clinic with breast problems. This study was conducted at Isra University Hospital Hyderabad and two other private hospitals of Hyderabad over a period of about three years starting from March 2004 to February 2007. All female patients visiting the surgical clinic with breast problems were included in the study. Patients with obvious clinical features of malignancy or those who on work up were diagnosed as carcinoma were excluded from the study. Results: A total of 275 patients were included in the study. About 44% (120/275) patients belonged to third decade of life (age between: 21-30 years) followed by 33% from forth decade (age between: 31- 40 years). Fibroadenoma was the most common benign breast disease, seen in 27% (75/275) of patients, followed by fibrocystic disease seen in about 21% (57/275) patients. Conclusion: Benign Breast Diseases (BBD) are common problems in females of reproductive age. Fibroadenoma is the commonest of all benign breast disease in our set up mostly seen in second and third decade of life. Fibrocystic disease of the breast is the next common BBD whose incidence increases with increasing age. (author)

    Benign breast disease is common, although the incidence is sparsely documented in the literature and is probably quite underestimated. The main reason is that it is regarded as unimportant, with far more attention being focused on breast cancer. However, benign breast disease is far more common than breast cancer.

    Full Text Available Nerve invasion by glandular epithelial cells in a lesion is usually regarded as invasive carcinoma. However, some benign conditions in the pancreas, prostate, breast and other organs may show involvement of nerve bundles by benign epithelial cells. We report an 18-year-old female with nerve invasion in benign breast disease. The lesion in her right breast revealed fibrocystic changes with ductal hyperplasia and stromal sclerosis. Perineural and intraneural involvement by bland-looking small ducts lined by 2 layers of cells including an outer layer of myoepithelial cells were found, suggestive of benign nerve invasion. There was no evidence of malignant cells in any of the sections. The patient remains well after 31 months of follow-up. About 44 cases of nerve invasion in benign breast diseases have been reported in the literature. It is necessary to carefully evaluate nerve involvement in breast lesions to avoid over-diagnosis and inappropriate operation.

    The possible association between cigarette smoking and the risk of benign breast disease (BBD) was assessed in a case-control study conducted in Gdansk, Poland, between 1990 and 1994. The study compared 160 women with newly diagnosed BBD admitted to the Gdansk Cancer Outpatients Clinic and 160 controls, women from outpatients clinics at the Medical University of Gdansk. There was no convincing evidence of an association, either positive or negative, between various indicators of smoking habit (smoking status, number of cigarettes smoked per day, duration of smoking) and the risk of BBD. Slightly lower relative risk (RRs) of BBD in ex-smokers of 10 or more cigarettes per day (RR = 0.9; 95% confidence interval, CI: 0.4-2.2), and with duration of smoking >= (RR = 0.1-3.4), were also observed in current smokers (RR = 0.8; 95% CI: 0.4-1.5), and (RR = 0.8; 95% CI: 0.1-3.4), but these findings were not statistically significant.

    Benign breast disease and high breast density are prevalent, strong risk factors for breast cancer. Women with both risk factors may be at very high risk. We included 42818 women participating in the Breast Cancer Surveillance Consortium who had no prior diagnosis of breast cancer and had undergone at least one benign breast biopsy and mammogram; 1359 women developed incident breast cancer in 6.1 years of follow-up (78.1% invasive, 21.9% ductal carcinoma in situ). We calculated hazard ratios (HRs) using Cox regression analysis. The referent group was women with nonproliferative changes and average density. All P values are two-sided. Benign breast disease and breast density were independently associated with breast cancer. The combination of atypical hyperplasia and very high density was uncommon (0.6% of biopsies) but was associated with the highest risk for breast cancer (HR = 5.34; 95% confidence interval [CI] = 3.52 to 8.09, P < .001). Proliferative disease without atypia (25.6% of biopsies) was associated with elevated risk that varied little across levels of density: average (HR = 1.37; 95% CI = 1.11 to 1.69, P = .003), high (HR = 2.02; 95% CI = 1.68 to 2.44, P < .001), or very high (HR = 2.05; 95% CI = 1.54 to 2.72, P < .001). Low breast density (4.5% of biopsies) was associated with low risk (HRs <1) for all benign pathology diagnoses. Women with high breast density and proliferative benign breast disease are at very high risk for future breast cancer. Women with low breast density are at low risk, regardless of their benign pathologic diagnosis.

    It has been suggested that breast and thyroid diseases may be linked. The aim of this study was to investigate the association between benign breast disease and subsequent risk of thyroid cancer. Postmenopausal women (n = 133,875) aged 50-79 years were followed up for a mean of 14 years. Benign breast disease was defined by history of biopsy. Incident thyroid cancer cases were confirmed by medical record review. Multivariable Cox proportional hazard modeling was used to estimate hazard ratios. There were 370 incident thyroid cancer cases during the follow-up period. Compared to women without BBD, women with BBD had a significant increased risk of thyroid cancer after adjusting for potential confounders (HR 1.38 95% CI 1.10-1.73), especially for women with more than two biopsies (HR 1.59 95% CI 1.10-2.26). There were no significant differences in thyroid tumor size, stage or histologic types between women with and without BBD. Our large prospective study observed that postmenopausal women with BBD had an increased risk for thyroid cancer compared with women without BBD. A more detailed investigation of thyroid cancer risk according to different subtypes of benign breast disease is needed to better understand the association observed between thyroid and benign breast diseases.

    Background: To study the patterns of clinically benign breast disease in females and to co-relate them with the pathological findings. Methods: One hundred females who attended the Surgery Outpatients Department in Indira Gandhi Medical College and Research Institute, Pondicherry, with various forms of benign breast diseases during the period from October 2011 to September 2012, were studied. Early diagnoses by doing a triple assessment like a clinical examination, FNAC or a core needle biopsy and imaging methods like ultrasonography or mammography, were made within 72 hrs from the first consultation. The clinical diagnoses were compared with the cytological or histological findings wherever possible and their accuracies were evaluated. Results: Out of the 100 female patients who were studied, 87 patients who presented with breast lumps and fibroadenoma, accounted for 48% of the cases, which was the highest number of patients. Fibrocystic changes and breast abscesses came next with 18% and 12% cases respectively. We detected 3 cases of proliferative disease with atypia and one case with florid hyperplasia, which had high and low risk factors respectively, for developing invasive carcinoma. The oldest lady of the group who was clinically diagnosed to have benign disease, was detected to have invasive ductal carcinoma. They were treated in our hospital and were advised follow up. Conclusion: Benign breast diseases are common in female patients and fibroadenoma is the commonest of them all. Triple assessment provided a quick diagnosis and it alleviated unnecessary anxiety from the patients about breast cancer. The clinical diagnosis of a breast lump, as confirmed by cytology and histology, was accurate in 91.95 % of the cases. PMID:23634406

    Radiological and pathological correlation of the full range of benign breast lesions, with emphasis on screen-detected lesions. Detailed discussion of risk assessment. Revised and updated edition, with a new chapter on gynaecomastia. Ideal aid to the management of patients with benign or indeterminate breast lesions in a multidisciplinary setting. The second edition of this book has been extensively revised and updated. There have been numerous scientific advances in the radiology, pathology and risk assessment of benign breast lesions since the publication of the first edition. The first edition concentrated on screen-detected lesions, which has since been rectified; new symptomatic and screen-detected lesions are discussed in the second edition and include: mastitis and breast abscesses, idiopathic granulomatous mastitis, diabetic mastopathy, phyllodes tumours, gynaecomastia and pseudoangiomatous stromal hyperplasia. The chapters on columnar cell lesions and mucocele-like lesions have been extensively updated. Where applicable, genetic analysis of the benign lesions, which is becoming part of personalised medicine in the field of breast cancer, has been included. The book also presents detailed analyses of the main models, such as the Gail Model, used to assess the subsequent risk of breast cancer in individuals. The current trend in the management of all cancers is preventative. Screening mammography detects early curable cancers as well as indeterminate lesions, the latter of which are invariably pathologically benign. The author has collated important benign lesions and, based on peer-reviewed publications, has documented the relative risk of subsequent cancer to allow the patient and the clinician to implement preventative measures where possible. This book will therefore serve as an essential component of multidisciplinary management of patients with symptomatic and screen-detected benign breast lesions.

    Full Text Available BACKGROUND Benign Breast diseases are of unknown aetiology, they could be inflammatory or non-inflammatory disorders of breast disease. Among these, NIBBD is a most confusing surgical disorder, diagnosis should be made at least after three assessments. AIM  To evaluate the prevalence of NIBBD.  Clinical analysis of NIBBD in women and reproductive age group between 20-40 years.  To prevent radical breast surgery in NIBBD.  To know about benign breast lesions in males excluding gynaecomastia. MATERIALS AND METHODS A clinicopathological study of NIBBD was taken in KIMS Hospital, Hubli, a tertiary care government hospital between June 2014 to June 2015. A total of 56 cases were selected of which 51 cases were submitted for clinicopathological study. RESULTS Increase incidents of fibroadenoma in females, in young age group, is noticed due to early menarche, early marriage, multiparity, fibrocystic diseases involvement at the age of 35 years, usually appear on either side of the breast. Moderate loss of glandular tissue is accelerated and replaced by connective tissue, hence fibrocystic diseases appear at late age group. Gynaecomastia is the only NIBBD, seen unilaterally in males. CONCLUSION NIBBD is more common in childbearing age group i.e. 15 to 45 years of age. Triple assessment is the choice of diagnosis, imaging modality being USG of the breast and mammography in suspected cases of malignancy. Most of the patients require surgical intervention and remodelling of the Breast, according to the volume loss of breast tissue.

  17. Impact of preventive therapy on the risk of breast cancer among women with benign breast disease.

    There are three main ways in which women can be identified as being at high risk of breast cancer i) family history of breast and/or ovarian cancer, which includes genetic factors ii) mammographically identified high breast density, and iii) certain types of benign breast disease. The last category is the least common, but in some ways the easiest one for which treatment can be offered, because these women have already entered into the treatment system. The highest risk is seen in women with lobular carcinoma in situ (LCIS), but this is very rare. More common is atypical hyperplasia (AH), which carries a 4-5-fold risk of breast cancer as compared to general population. Even more common is hyperplasia of the usual type and carries a roughly two-fold increased risk. Women with aspirated cysts are also at increased risk of subsequent breast cancer. Tamoxifen has been shown to be particularly effective in preventing subsequent breast cancer in women with AH, with a more than 70% reduction in the P1 trial and a 60% reduction in IBIS-I. The aromatase inhibitors (AIs) also are highly effective for AH and LCIS. There are no published data on the effectiveness of tamoxifen or the AIs for breast cancer prevention in women with hyperplasia of the usual type, or for women with aspirated cysts. Improving diagnostic consistency, breast cancer risk prediction and education of physicians and patients regarding therapeutic prevention in women with benign breast disease may strengthen breast cancer prevention efforts.

    Full Text Available Myoepithelioma of the breast is very rare. Breast myoepithelioma can develop in women from their early 20s right up to their 80s, but it is most common in women over 50. We report a case of 20-year-old female, who presented with a well-defined breast lump of 3 × 3 cm in size. Fine needle aspiration was performed. The cytological findings revealed good cellularity comprising monomorphic loosely cohesive sheets of plasmacytoid, round to polygonal cells with round to ovoid eccentrically placed nuclei, finely dispersed chromatin, and moderate amount of cytoplasm. On the basis of cytological findings, a diagnosis of benign myoepithelioma (plasmacytoid type was made which was confirmed on histopathologic examination. The breast is a very rare localization for this type of tumor. The benign character of the disease in conjunction with its slow progression could delay its detection and diagnosis. A detailed pathology examination is a prerequisite for avoidance of misleading diagnosis.

  19. Identifying Two Common Types of Breast Benign Diseases Based on Multiphoton Microscopy

    Full Text Available Multiphoton microscopy has attracted increasing attention and investigations in the field of breast cancer, based on two-photon excited fluorescence (TPEF and second-harmonic generation (SHG. However, the incidence of breast benign diseases is about 5 to 10 times higher than breast cancer; up to 30% of women suffer from breast benign diseases and require treatment at some time in their lives. Thus, in this study, MPM was applied to image fibroadenoma and fibrocystic lesion, which are two of the most common breast benign diseases. The results show that MPM has the capability to identify the microstructure of lobule and stroma in normal breast tissue, the interaction of compressed ducts with surrounding collagen fiber in fibroadenoma, and the architecture of cysts filled with cystic fluid in fibrocystic disease. These findings indicate that, with integration of MPM into currently accepted clinical imaging system, it has the potential to make a real-time diagnosis of breast benign diseases in vivo, as well as breast cancer.

    Women with proliferative breast lesions are candidates for primary prevention, but few risk models incorporate benign findings to assess breast cancer risk. We incorporated benign breast disease (BBD) diagnoses into the Breast Cancer Surveillance Consortium (BCSC) risk model, the only breast cancer risk assessment tool that uses breast density. We developed and validated a competing-risk model using 2000 to 2010 SEER data for breast cancer incidence and 2010 vital statistics to adjust for the competing risk of death. We used Cox proportional hazards regression to estimate the relative hazards for age, race/ethnicity, family history of breast cancer, history of breast biopsy, BBD diagnoses, and breast density in the BCSC. We included 1,135,977 women age 35 to 74 years undergoing mammography with no history of breast cancer; 17% of the women had a prior breast biopsy. During a mean follow-up of 6.9 years, 17,908 women were diagnosed with invasive breast cancer. The BCSC BBD model slightly overpredicted risk (expected-to-observed ratio, 1.04; 95% CI, 1.03 to 1.06) and had modest discriminatory accuracy (area under the receiver operator characteristic curve, 0.665). Among women with proliferative findings, adding BBD to the model increased the proportion of women with an estimated 5-year risk of 3% or higher from 9.3% to 27.8% (P<.001). The BCSC BBD model accurately estimates women's risk for breast cancer using breast density and BBD diagnoses. Greater numbers of high-risk women eligible for primary prevention after BBD diagnosis are identified using the BCSC BBD model. © 2015 by American Society of Clinical Oncology.

    Purpose To examine the breast cancer risk overall among women with simple fibroadenoma or complex fibroadenoma and to examine the association of complex fibroadenoma with breast cancer through stratification of other breast cancer risks. Methods The study included women aged 18 to 85 years from the Mayo Clinic Benign Breast Disease Cohort who underwent excisional breast biopsy from 1967 through 1991. Within this cohort, women who had fibroadenoma were compared to women who did not have fibroadenoma. Breast cancer risk (observed vs expected) across fibroadenoma levels was assessed through standardized incidence ratios (SIRs) by using age- and calendar-stratified incidence rates from the Iowa Surveillance, Epidemiology, and End Results registry. Analyses were performed overall, within subgroups of involution status, with other demographic characteristics (age, year of biopsy, indication for biopsy, and family history), and with histologic characteristics, including overall impression (nonproliferative disease, proliferative disease without atypia [PDWA], or atypical hyperplasia). Results Fibroadenoma was identified in 2,136 women (noncomplex, 1,835 [85.9%]; complex, 301 [14.1%]). SIR for noncomplex fibroadenoma was 1.49 (95% CI, 1.26–1.74); for complex fibroadenoma, it was 2.27 (95% CI, 1.63–3.10) (test for heterogeneity in SIR, P=.02). However, women with complex fibroadenoma were more likely to have other, concomitant high-risk histologic characteristics (eg, incomplete involution and PDWA). In analyses stratified by involution status and PDWA, complex fibroadenoma was not an independent risk marker for breast cancer. Conclusions Complex fibroadenoma does not confer increased breast cancer risk beyond other established histologic characteristics. PMID:26264469

    Benign breast disease increases the risk of breast cancer. This association has scarcely been evaluated in the context of breast cancer screening programs although it is a prevalent finding in mammography screening. We assessed the association of distinct categories of benign breast disease and subsequent risk of breast cancer, as well as the influence of a family history of breast cancer. A retrospective cohort study was conducted in 545,171 women aged 50-69 years biennially screened for breast cancer in Spain. The median of follow-up was 6.1 years. The age-adjusted rate ratio (RR) of breast cancer for women with benign breast disease, histologically classified into nonproliferative and proliferative disease with and without atypia, compared with women without benign breast disease was estimated by Poisson regression analysis. A stratified analysis by family history of breast cancer was performed in a subsample. All tests were two-sided. The age-adjusted RR of breast cancer after diagnosis of benign breast disease was 2.51 (95 % CI: 2.14-2.93) compared with women without benign breast disease. The risk was higher in women with proliferative disease with atypia (RR = 4.56, 95 % CI: 2.06-10.07) followed by those with proliferative disease without atypia (RR = 3.58; 95 % CI = 2.61-4.91). Women with nonproliferative disease and without a family history of breast cancer remained also at increased risk of cancer (OR = 2.23, 95 % CI: 1.86-2.68). An increased risk of breast cancer was observed among screening participants with proliferative or nonproliferative benign breast disease, regardless of a family history of breast cancer. This information may be useful to explore risk-based screening strategies.

    Full Text Available AIMS AND OBJECTIVES: The presence of a lump in the breast is a great cause of anxiety and apprehension, to the female patients. This may be accrued to the increasing public awareness of breast cancer which is presently the most common female malignancy worldwide. The aim of th is study was to determine the frequency of benign breast diseases (BBD amongst patients in tertiary care institute of central India. MATERIAL AND METHOD: It was a cohort study. In this study all patients visiting the surgical OPD clinic with breast proble ms were included. This study was conducted at Chirayu Medical College and Hospital Bhopal over a period of four years starting from November 2010 to November 2014. All patients with definite symptoms and sign of malignancy or those who on evaluation were d iagnosed as carcinoma of breast were excluded from this study. RESULTS: A total of 112 patients were included in the study. About 54.4% (61/112 patients belonged to 3rd decade of life followed by 21.4% (24/112 from 4th decade (age between: 31 – 40 years . The most common benign breast disease, seen in 33.9% (38/112 of patients was fibro adenoma followed by fibrocystic disease seen in about 19.6% (22/112 patients. Breast abscess was seen in 20/112(17.8% and Mastalgia was present in 15/112 (13.3% patien ts. CONCLUSION: In females of reproductive age group Benign Breast Diseases (BBD are common problems. Fibro adenoma is the commonest of all benign breast disease mostly seen in 2nd and 3rd decade of life. Fibrocystic disease of the breast is the next comm on BBD whose incidence increases with increasing age. Routine mammographic screening of high risk groups aimed at early detection of these premalignant lesions is therefore indicated. A biopsy with histological diagnosis of all breast lumps is also recomme nded as this will aid in the detection of premalignant lesions particularly in low resource settings

    Established risk factors for breast cancer explain breast cancer risk only partially. Organochlorines are considered to be a possible cause for hormone-dependent cancers. A hospital-based case-control study, the first from India, was conducted among 50 women undergoing surgery for breast disease to examine the association between organochlorine exposure and breast cancer risk. Blood, tumor, and surrounding adipose tissue of the breast were collected from the subjects with benign (control) and malignant breast (study) lesions and analyzed to determine organochlorine insecticides using a gas-liquid chromatograph equipped with an electron capture detector. The α, β, γ, and δ isomers of hexachlorocyclohexane (HCH), p,p'-dichlorodiphenyltrichloroethane (DDT), o,p'-DDT, p,p-dichlorodiphenyldichloroethylene, and p,p'-dichlorodiphenyldichloroethane were frequently detected in three specimens. Total HCH and total DDT levels were higher in the blood of the study group (25 cases) than in those of the controls (25 cases) with only γ-HCH being significantly different (P0.05). However, both total HCH and total DDT were higher in the tumor tissues of the controls than in those of the study group; γ-HCH was significantly different (P0.05). The level of total HCH (α-HCH was significantly different, P0.05) was higher in the breast adipose tissue of the study group, whereas total DDT was higher in the breast adipose tissue of the control group. The distribution of known confounders of breast cancer including age, body mass index, age at menarche and menopause, duration of breast feeding, and family history related to breast disease did not differ significantly between benign and malignant groups. This pilot study with limited statistical power does not support a positive association between exposure to organochlorines and risk of breast cancer but paves the way for a larger Indian study with greater statistical power encompassing different regions of the country to enable

    Full Text Available Increasing evidences indicate involvement of free radicals in the pathogenesis of benign and malignant breast diseases. Free radicals are highly reactive molecules and react with non–radicals in chain reaction leading to formation of new free radicals. If the defense mechanism of body fails to combat them, these free radicals pose a threat of injuring tissues by reacting with cell lipids. Lipids in the cell membrane undergo degradation to form hydroperoxides, which decompose to form a variety of products including malondialdehyde (MDA. MDA therefore was used as a marker to assess oxidative damage of cells and tissues. The aim of the present study was to assess the status of oxidative stress in the patients of benign and malignant breast diseases. Study has been made on the blood samples of 25 cases of benign breast disease and on an equal number of breast carcinoma patients. 20 healthy subjects were taken as the control cases.Mean MDA levels were significantly raised with depletion of antioxidant activity in all the patients in comparison to their control group suggesting the role of oxidative damage in the aetiopathogenesis of disease.

    Shear wave elastography (SWE) is an emerging technique which can obtain quantitative elasticity values in breast disease. We therefore evaluated the diagnostic performance of SWE for the differentiation of breast masses compared with conventional ultrasound (US). Conventional US and SWE were performed by three experienced radiologists for 158 consecutive women who had been scheduled for US-guided core biopsy or surgical excision in 182 breast masses (89 malignancies and 93 benign; mean size, 1.76 cm). For each lesion, quantitative elasticity was measured in terms of the Young's modulus (in kilopascals, kPa) with SWE, and BI-RADS final categories were assessed with conventional US. The mean elasticity values were significantly higher in malignant masses (153.3 kPa ± 58.1) than in benign masses (46.1 kPa ± 42.9), (P masses as well as invasive and intraductal cancers with SWE. Our results suggest that SWE has the potential to aid in the differentiation of benign and malignant breast lesions.

    Full Text Available Breast cancer is a multifactorial disease. Benign breast disease (BBD is one of the most important risk factors for breast cancer. The etiology of BBD is unknown. It is divided into nonproliferative and proliferative diseases. The selection of studies will be based on titles, abstract screening, inclusion and exclusion criteria, and quality assessment. Previous studies have shown that all types of BBD increase the risk of breast cancer, but the risk degree is different for each one. Accurate risk estimation of breast cancer in each category can be very important for proper clinical management. This systematic review and meta-analysis will be conducted on observational studies (traditional case control, nested case control, case cohort, and cohort published in the Web of Science (ISI, PubMed (MEDLINE, Scopus, Google Scholar, and the key journals of this field such as Breast Cancer Research and Treatment and Cancer Research from January 2000 to June 2015.

    The objective of this study was to examine the association between flame-broiled food consumption, a source of heterocyclic amine exposure, and the development of breast cancer among cohort of women with benign breast disease (BBD). The variation of the association by acetylation phenotype, as determined by the genotypes of selected N-acetyltransferase 2 (NAT2) enzymes, was also examined. Among participants in an ongoing cohort study, 1187 women reported having a breast biopsy for BBD and completed a food frequency questionnaire. NAT2 G857A, NAT2 T341C, and NAT2 G590A genotypes were determined using DNA extracted from blood specimens collected in 1989. Incident cases of breast cancer were identified through linkage of the cohort participants with the Washington County Cancer Registry and the Maryland State Cancer Registry. Follow-up for the BBD cohort began at study entry in 1989 and ended on April 28, 2003. Of the women in this study, 77 subsequently developed breast cancer. Results showed that, among rapid acetylators, flame-broiled food intake was associated with a statistically significant increase in the risk of breast cancer (odds ratio (OR) 2.62; 95% confidence interval (CI) 1.06, 6.46). No association was observed between flame-broiled food intake and breast cancer among slow acetylators (OR 0.75; 95% CI 0.39, 1.43). These findings suggest that flame-broiled food may be a modifiable risk factor for the progression of BBD to invasive breast cancer among women who have genotypes consistent with rapid acetylation.

    Objective was to characterize benign breast diseases in Eastern Nigeria and to highlight the age variations of these lesions as base line data. The Department of Morbid Anatomy, University of Nigeria Teaching Hospital, Enugu caters for over 30 million African blacks and receives 2000 surgical pathology specimens yearly. Seven hundred and twenty-two benign breast specimens were analyzed over 5 years from Ist January 2000 to 31 December 2004, out of 1050 breast samples received. Of 1050 breast specimens received, 722 (68.8%) were benign. Fibroadenoma was the most common lesion with 318 cases (44%), occurring at a mean age of 16-32 years. Next were fibrocystic changes with 165 cases (22.9%) at a mean age of 23-45 years. Normal breast in the axillary tail region was seen in 32 cases (4.4%), represented as no pathology, with a mean presentation age of 20-46 years. Low grade Phyllodes tumor had 28 cases (3.9%), presenting at an average mean age of 17-32 years. Lactating adenoma had 19 (2.6%) cases. Other lesions made up less than 3% each. Benign breast lesions peaked at the 20-24 age range and then declined. Most were females. Benign breast lesions occur more frequently than malignant breast lesions with a ratio of 2.3:1 and were presented 20 years earlier than their malignant counterparts. Fibroadenoma was the most common benign lesions followed by fibrocystic disease, similar to the findings in Western Nigeria. In Northern Nigeria, fibrocystic breast disease was more common. (author)

    Fibrocystic mastosis (FCM) is defined by the totality of dystrophic changes of the mammary tissue, the grouping in the form of fibrosis of epithelial, cystic, metaplastic and hyperplastic alterations. A very good estimation of the cancer risk is related specifically to the microscopic aspect. Other factors, the family history as well as the presence of an inherited gene determining the increase in the risk of breast cancer are also considered. But, if a woman known with fibrocystic mastosis has not undergone any biopsy, then it is impossible to calculate the specific individual risk of developing cancer. The data collected as a study material and considered refer to: the total num- ber of cases investigated and diagnosed with fibrocystic mastosis, the annual distribution of this disease cases, the distribution of the cases according to age groups, admission reasons, clinical examination, personal pathologic history clinically significant for the basic disease (the main diagnosis), the family medical history significant for the basic disease, the anatomopathological diagnosis. Between 2004 and 2006, at "Cuza Vodă" Obstetrics and Gynecology Hospital of Iaşi, a maximum number of cases is noticed in 2006, when there were 147 cases, and the lowest number of cases was in 2005. There was high frequency of the anatomopathological examinations that highlighted the presence of fibrocystic lesions (both proliferative and non-proliferative), and the second most often diagnosis is fibroadenoma. Though fibrocystic mastosis is not clearly defined, it is still admitted that in order to support this diagnosis it is first compulsory to exclude malignant tumours. Only in 5% of the women with fibrocystic mastosis cellular changes can be revealed in the form of atypical hyperplasia, which are a risk factor for cancer. The lesion that delimits cancer from non-cancer is ductal carcinoma in situ. An incidence of over 20% is present in the countries that use mammographic screening

    A case-control study was undertaken to investigate the role of diet in women with breast cancer, and in two groups of women with benign breast disease: epithelial hyperplasia, and fibrocystic disease without hyperplasia. The study provides data which suggest that the consumption of red meat, savoury meals (pizza, pies, stew, etc.) and of starches is disadvantageous, while the consumption of chicken and fish, and of fruit, appears to be beneficial. These patterns were present for both the breast cancer patients and the patients with benign epithelial hyperplasia. One-third of breast cancer patients had changed their diet after their diagnosis, compared to only around 12% in controls and patients with benign breast disease. Overall, the women studied had changed their diet to reduce their intake of sugars, dairy products and meat, and increased their intake of poultry, fish, fruit and vegetables over the past decade; but the breast cancer group was less likely to have made this change.

    514 patients with benign breast disease provided records from multicentre studies in the U.S.A. Results showed that a high proportion responded with either decrease or elimination of symptoms, response usually being apparent 15 to 45 days after commencing treatment. Dosage schedules varied between 50 and 400 mg danazol daily and length of treatment between 15 and 196 days. There was a tendency for patients with more severe symptoms to respond better to the higher dosages, and for the elimination rate for all grades of severity to improve with time. Side effects were not severe, and of the expected type including weight gain, oiliness of skin and hair, and acne.

    The most important factor in predicting outcome in patients with early breast cancer is the stage of the disease. There is no robust marker capable of identifying invasive carcinomas that despite their small size have a high metastatic potential, and that would benefit from more aggressive treatment. RhoC-GTPase is a member of the Ras-superfamily and is involved in cell polarity and motility. We hypothesized that RhoC expression would be a good marker to identify breast cancer patients with high risk of developing metastases, and that it would be a prognostic marker useful in the clinic. We developed a specific anti-RhoC antibody and studied archival breast tissues that comprise a broad spectrum of breast disease. One hundred eighty-two specimens from 164 patients were used. Immunohistochemistry was performed on formalin-fixed tissues. Staining intensity was graded 0 to 3+ (0 to 1+ was considered negative and 2 to 3+ was considered positive). RhoC was not expressed in any of the normal, fibrocystic changes, atypical hyperplasia, or ductal carcinoma in situ, but was expressed in 36 of 118 invasive carcinomas and strongly correlated with tumor stage (P = 0.01). RhoC had high specificity (88%) in detecting invasive carcinomas with metastatic potential. Of the invasive carcinomas smaller than 1 cm, RhoC was highly specific in detecting tumors that developed metastases. RhoC expression was associated with negative progesterone receptor and HER-2/neu overexpression. We characterized RhoC expression in human breast tissues. RhoC is specifically expressed in invasive breast carcinomas capable of metastasizing, and it may be clinically useful in patients with tumors smaller than 1 cm to guide treatment. PMID:11839578

    Full Text Available Abstract Background Minimal invasive breast biopsy is standard care for the diagnosis of suspicious breast lesions. There are different vacuum biopsy (VB systems in use. The aim of the study was to determine the differences between the 8-gauge and the 11-gauge needle with respect to a diagnostic reliability, b complication rate and c subjective perception of pain when used for vacuum-assisted breast biopsy. Methods Between 01/2000 and 09/2004, 923 patients at St. Josefs-Hospital Wiesbaden underwent VB using the Mammotome® (Ethicon Endosurgery, Hamburg. Depending on preoperative detection, the procedure was performed under sonographic or mammographic guidance under local anaesthesia. All patients included in the study were followed up both clinically and using imaging techniques one week after the VB and a second time after a median of 41 months. Excisional biopsy on the ipsilateral breast was an exclusion criteria. Subjective pain scores were recorded on a scale of 0 – 10 (0 = no pain, 10 = unbearable pain. The mean age of the patients was 53 years (30 – 88. Results 123 patients were included in the study in total. 48 patients were biopsied with the 8-gauge needle and 75 with the 11-gauge needle. The use of the 8-gauge needle did not show any significant differences to the 11-gauge needle with regard to diagnostic reliability, complication rate and subjective perception of pain. Conclusion Our data show that there are no relevant differences between the 8-gauge and 11-gauge needle when used for VB. Under sonographic guidance, the use of the 8-gauge needle is recommended for firm breast tissue due to its sharp scalpel point and especially for complete removal of benign lesions. We did not find any advantages in the use of the larger 8-gauge needle compared to the 11-gauge needle in the mammography setting. The utilisation costs of the 8-gauge needle are somewhat higher.

    To explore the value of application of support vector machine-recursive feature elimination (SVM-RFE) method in Raman spectroscopy for differential diagnosis of benign and malignant breast diseases. Fresh breast tissue samples of 168 patients (all female; ages 22-75) were obtained by routine surgical resection from May 2011 to May 2012 at the Department of Breast Surgery, the First Hospital of Jilin University. Among them, there were 51 normal tissues, 66 benign and 51 malignant breast lesions. All the specimens were assessed by Raman spectroscopy, and the SVM-RFE algorithm was used to process the data and build the mathematical model. Mahalanobis distance and spectral residuals were used as discriminating criteria to evaluate this data-processing method. 1 800 Raman spectra were acquired from the fresh samples of human breast tissues. Based on spectral profiles, the presence of 1 078, 1 267, 1 301, 1 437, 1 653, and 1 743 cm(-1) peaks were identified in the normal tissues; and 1 281, 1 341, 1 381, 1 417, 1 465, 1 530, and 1 637 cm(-1) peaks were found in the benign and malignant tissues. The main characteristic peaks differentiating benign and malignant lesions were 1 340 and 1 480 cm(-1). The accuracy of SVM-RFE in discriminating normal and malignant lesions was 100.0%, while that in the assessment of benign lesions was 93.0%. There are distinct differences among the Raman spectra of normal, benign and malignant breast tissues, and SVM-RFE method can be used to build differentiation model of breast lesions.

    A cohort study was conducted to examine the role of genetic polymorphisms in three estrogen metabolizing enzymes (COMT, CYP1A1, CYP1B1) and the two estrogen receptors (ESR1, ESR2) in the progression of benign breast disease (BBD) to breast cancer. Among participants in an ongoing cohort study, 1438 Caucasian women had a breast biopsy for BBD and were successfully genotyped for at least one of the polymorphisms examined in this study. Genotypes were determined using DNA extracted from blood specimens collected in 1989. Incident cases of breast cancer occurring subsequent to BBD diagnosis up to 2003 were identified through cancer registries. Among all participants, the ESR2 *5772G allele was associated with a significant decrease in the risk of breast cancer among women with BBD (Odds Ratio (OR) 0.38; 95% Confidence Interval (CI) 0.15, 0.96). Compared to the reference wild-type genotypes, marginally significant associations with the development of breast cancer were observed between carriers of the variant ESR1 – 104062T allele (OR 0.70, 95% CI 0.45, 1.09), the variant ESR2 *38A allele (OR 1.40; 95% CI 0.88, 2.25), and the variant CYP1B1 453Ser allele (OR 1.48, 95% CI 0.95, 2.32). The results indicate that specific polymorphisms in the CYP1B1, ESR1, and ESR2 genes may play a role in progression of BBD to breast cancer among Caucasian women. Although additional studies are needed to confirm or refute our findings, these results suggest that genetic markers may aid in the identification of women who are at risk for progression of BBD to cancer

    In adult women with retrospective data, childhood adiposity, pubertal growth and development were associated with benign breast disease (BBD) and/or breast cancer. The authors prospectively evaluated these childhood/adolescent characteristics and BBD risk. The Growing Up Today Study (GUTS) included females, aged 9-15 years in 1996, who completed annual questionnaires through 2001, then 2003, 2005, and 2007. Participants annually/biennially provided information on menarche, height, and weight, from which the authors derived body mass index (BMI in kg/m(2) ). Peak height growth velocity (PHV in cm/year) was estimated from longitudinal data. On 2005-2007 surveys, 6899 females (18-27 years of age) reported whether a healthcare provider ever diagnosed BBD (n = 147), and whether it was confirmed by biopsy (n = 67). Logistic models investigated risk factors adjusted for age, alcohol, pregnancy, and maternal history. More childhood adiposity (odds ratio [OR], 0.91/[kg/m(2) ]; P = .04) and shorter adult height (OR, 0.93/inch shorter; P = .07) were associated with lower risk of biopsy-confirmed BBD. Girls with most rapid height growth were at increased risk (OR, 2.12; P = .09) relative to those with the slowest growth. Age at menarche was not associated (OR, 1.11/year; P = .32) nor was adult BMI (adjusted for childhood BMI: OR, 1.01/[kg/m(2) ]; P = .98); larger BMI increases (childhood to adulthood) were not protective (OR + 1.04/[kg/m(2) ]; P = .37). Among girls with maternal breast cancer, those with more rapid growth had higher risk (OR, 1.47/[cm/year]; P = .02). All estimates were age-adjusted. Increased BBD risk (likely evolving to elevated breast cancer risk) was observed in thinner girls, girls with the most rapid growth, and taller women. Contrary to expectations, later menarche age was not protective against BBD, consistent with studies that found BBD patients are not protected against breast cancer by later menarche.

    The relation between suicidal ideation versus hopelessness/helplessness in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared to date in a prospective study. We, therefore, investigated suicidal ideation versus hopelessness/helplessness in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness versus suicidal/pessimistic thoughts before any diagnostic procedures were carried-out. In the self-rating score (SRS), hopelessness and the helplessness versus pessimistic thoughts were significantly correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa-values for hopelessness versus pessimistic thoughts in the BBD group were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) in the hopelessness versus pessimistic thoughts in the HSS, BBD and BC groups, as well as in the ERS, in the helplessness versus pessimistic thoughts in the HSS and BBD groups. In SRS, the hopelessness and the helplessness versus suicidal thoughts were significantly correlated in the HSS, BBD and BC groups. There was also a significant positive correlation in the ERS in the hopelessness versus suicidal thoughts in the HSS, BBD and BC groups, as well as in the ERS, in the helplessness versus suicidal thoughts in the BBD group. A new finding with clinical relevance in the present work is the agreement between hopelessness/helplessness versus suicidal/pessimistic thoughts in the self-rating and examiner-rating. In the breast cancer diagnostic Unit, the identification of suicidal ideation is essential in suicide prevention and it is important to assess and treat depression even though a subject reports little suicidal ideation.

    Full Text Available The current study aims to summarize breast anthropomorphic measurement features in Chinese patients with breast diseases and to investigate their potential correlations with demographic factors.Fifteen breast anthropomorphic parameters of 605 Chinese female patients were collected prospectively. Breast ptosis status was scaled by two methods and breast volume was calculated according to a modified formula of BREAST-V.Among 1210 breasts, the average breast volume was 340.0±109.1 ml (91.8-919.2 ml. The distance from the nipple to the inframammary fold was 7.5±1.6 cm in the standing position. The width of the breast base was 14.3±1.4 cm (8.5-23.5 cm. The incidence of breast ptosis was 22.8% (274/1204, of which 37 (23.5% and 79 (31.7% women had severe ptosis assessed by different criteria. Increased height (OR[odds ratio] = 1.500, P<0.001, post-menopausal status (OR = 1.463, P = 0.02, increased BMI, breastfeeding for 7-12 months (OR = 1.882, P = 0.008 and more than one year (OR = 2.367, P = 0.001 were risk factors for an increased breast volume. Post-menopausal status (OR = 2.390, P<0.001 and OR = 2.621, P<0.001 for different scales, BMI≥24.7 kg/m2 (OR = 3.149, P<0.001 and OR = 2.495, P = 0.002, breastfeeding for 7-12 months (OR = 4.136, P = 0.004 and OR = 4.010, P = 0.002, and breastfeeding for more than one year (OR = 6.934, P<0.001 and OR = 6.707, P<0.001 were independent risk factors for breast ptosis.The current study provides anthropomorphic measurements data of Chinese women with breast diseases, which are useful for cosmetic and reconstructive breast surgery decisions. Post-menopausal status, increased BMI, and breastfeeding for more than six months were independent risk factors for both increased breast volume and breast ptosis.

    The report deals with an estimation of the volume of radiation treatment of benign diseases in Norway and gives a survey of the subjective opinion of patients regarding the result of the treatment. Reported subjective recovery after radiation treatment seems to be at the same level as recovery without treatment. For an indication of the objective effect of radiation treatment of benign diseases, the subjective effect of this treatment has to be compared with objective findings

    We assessed the usefulness of resistive index(RI) on spectral analysis of doppler sonography for differential diagnosis of benign and malignant breast lesions. We retrospectively reviewed 29 benign and 22 malignant lesions of breast, which were examined preoperatively with color and duplex Doppler and were confirmed by histopathologically after operation. We analyzed the average and distribution of RI in benign and malignant lesions. Although, there was no difference in the average values of RI in benign and malignant breast lesions, the distribution of RI was below 0.7 in eighteen cases (62%) of benign lesions, and above 0.7 in eighteen cases (82%) of malignant lesions. Thus, RI is valuable for differentiation between benign and malignant lesions of breast. Measurement of RI in breast disease using color and duplex Doppler study is useful modality adjunct to the conventional ultrasonographic differentiation of benign and malignant lesions

    Benign breast lesion is an important risk factor for breast cancer and elevated CA-15.3 in serum is a well established marker of breast cancer. Core-needle biopsy is now the method of choice to sample non-palpable mammographic abnormality and as well as clinically palpable lesion. To asses relationship of serum CA-15.3 with different histologic entities of benign breast lesion and usefulness of this marker in predicting breast cancer in this high risk group, a study was conducted among 140 patients who had a diagnosis of benign breast lesion and malignancy following fine needle aspiration cytology (FNAC) at department of surgery, Medical College, Kolkata between 2007 and 2009. We prospectively estimated serum CA-15.3 level in all patients. Different histologic entities of benign breast lesion, who showed serum CA-15.3 level >30U/ml underwent tru-cut biopsy to detect malignancy. Of 140 patients studied, 50 were stamped as malignancy and 90 as benign after FNAC of which 20 patients had fibroadenoma, 25 had fibro-adenoma with fibrocystic disease, 20 had fibrocystic disease with epitheliosis and 25 had fibrocystic disease with atypia. All breast cancer patients and 10 each from fibro-adenoma with fibrocystic disease, fibrocystic disease with epitheliosis and fibrocystic disease with atypia had serum CA -15.3 level>30U/ml. Thirty patients with benign breast lesion who had raised CA-15.3 underwent core-needle biopsy. Fifteen patients were detected to have intraductal carcinoma, mostly with fibrocystic disease with atypia. Clinical applicability of serum CA-15.3 to detect breast cancer should be strongly considered in management of patients with benign breast lesion and tru-cut biopsy than FNAC be done before benign breast lesion being stamped as benign. Biopsy results that are not concordant with the targeted lesion require surgical biopsy.

    Whipple\\'s procedure is the treatment of choice for pancreatic and periampullary malignancies. Preoperative histological confirmation of malignancy is frequently unavailable and some patients will subsequently be found to have benign disease. Here, we review our experience with Whipple\\'s procedure for patients ultimately proven to have benign disease. The medical records of all patients who underwent Whipple\\'s procedure during a 15-year period (1987-2002) were reviewed; 112 patients underwent the procedure for suspected malignancy. In eight cases, the final histology was benign (7.1%). One additional patient was known to have benign disease at resection. The mean age was 50 years (range: 30-75). The major presenting features included jaundice (five), pain (two), gastric outlet obstruction (one), and recurrent gastrointestinal haemorrhage (one). Investigations included ultrasound (eight), computerised tomography (eight), endoscopic retrograde cholangiopancreatography (seven; of these, four patients had a stent inserted and three patients had sampling for cytology), and endoscopic ultrasound (two). The pathological diagnosis included benign biliary stricture (two), chronic pancreatitis (two), choledochal cyst (one), inflammatory pseudotumour (one), cystic duodenal wall dysplasia (one), duodenal angiodysplasia (one), and granular cell neoplasm (one). There was no operative mortality. Morbidity included intra-abdominal collection (one), anastomotic leak (one), liver abscess (one), and myocardial infarction (one). All patients remain alive and well at mean follow-up of 41 months. Despite recent advances in diagnostic imaging, 8% of the patients undergoing Whipple\\'s procedure had benign disease. A range of unusual pathological entities can mimic malignancy. Accurate preoperative histological diagnosis may have allowed a less radical operation to be performed. Endoscopic ultrasound-guided fine needle aspirate (EUS-FNA) may reduce the need for Whipple\\'s operation

    Full Text Available It is known that benign breast tissue exhibit relatively low angiogenic capacity. Activation of angiogenesis in mammary pre-malignant lesions could be associated with disease progression and high risk of transformation into the breast cancer. However, insight into the underlying molecular mechanisms involved in angiogenesis regulation in non-cancerous breast pathologies is still poorly defined. The purpose of the present study was to determine levels of plasminogen and its proteolytic fragments (angiostatins in mammary dysplasia (mastopathy and breast cyst and benign neoplasms (fibroadenomas. Plasminogen and angiostatins were analyzed using immunoblotting and quantified by densitometric scanning. The significant increase in plasminogen levels was found in fibrocystic, cysts, and non-proliferatious fibroadenoma masses (4.7-, 3.7-, and 3.5-fold, respectively compared to healthy breast tissues (control. In the same benign lesions, 6.7-, 4-, and 3.7-fold increase in plasminogen 50 kDa fragment (angiostatin levels as compared with control were also observed. Activation of matrix metalloproteinase-9, which was detected using gelatine zymography, could be responsible for plasminogen cleavage and abundance of angiostatin in fibrocystic and cyst masses. In contrast, dramatic decrease of both plasminogen and angiostatin levels (3.8- and 5.3-folds, respectively was shown in tissues of proliferatious form of fibroadenoma in comparison with that of the dormant type of this neoplasm. Based on the obtained results, we concluded that angiostatin, a potent vessel growth inhibitor and anti-inflammatory molecule, can play a crucial role in pathophysiology of non-cancerous breast diseases. Further studies are needed to evaluate potential diagnostic and clinical implications of these proteins for prediction and therapy of benign breast pathologies.

    The purpose of this study was to investigate the utility of diffusion-weighted imaging (DWI) and the apparent diffusion coefficient (ADC) value in differentiating benign and malignant breast lesions and evaluating the detection accuracy of the cancer extension. We used DWI to obtain images of 191 benign and malignant lesions (24 benign, 167 malignant) before surgical excision. The ADC values of the benign and malignant lesions were compared, as were the values of noninvasive ductal carcinoma (NIDC) and invasive ductal carcinoma (IDC). We also evaluated the ADC map, which represents the distribution of ADC values, and compared it with the cancer extension. The mean ADC value of each type of lesion was as follows: malignant lesions, 1.22±0.31 x 10 -3 mm 2 /s; benign lesions, 1.67±0.54 x 10 -3 mm 2 /s; normal tissues, 2.09±0.27 x 10 -3 mm 2 /s. The mean ADC value of the malignant lesions was statistically lower than that of the benign lesions and normal breast tissues. The ADC value of IDC was statistically lower than that of NIDC. The sensitivity of the ADC value for malignant lesions with a threshold of less than 1.6 x 10 -3 mm 2 /s was 95% and the specificity was 46%. A full 75% of all malignant cases exhibited a near precise distribution of low ADC values on ADC maps to describe malignant lesions. The main causes of false negative and underestimation of cancer spread were susceptibility artifact because of bleeding and tumor structure. Major histologic types of false-positive lesions were intraductal papilloma and fibrocystic diseases. Fibrocystic diseases also resulted in overestimation of cancer extension. DWI has the potential in clinical appreciation to detect malignant breast tumors and support the evaluation of tumor extension. However, the benign proliferative change remains to be studied as it mimics the malignant phenomenon on the ADC map. (author)

    Terminal duct lobular units (TDLUs) are the primary structures from which breast cancers and their precursors arise. Decreased age-related TDLU involution and elevated mammographic density are both correlated and independently associated with increased breast cancer risk, suggesting that these characteristics of breast parenchyma might be linked to a common factor. Given data suggesting that increased circulating levels of insulin-like growth factors (IGFs) factors are related to reduced TDLU involution and increased mammographic density, we assessed these relationships using validated quantitative methods in a cross-sectional study of women with benign breast disease. Serum IGF-I, IGFBP-3 and IGF-I:IGFBP-3 molar ratios were measured in 228 women, ages 40-64, who underwent diagnostic breast biopsies yielding benign diagnoses at University of Vermont affiliated centers. Biopsies were assessed for three separate measures inversely related to TDLU involution: numbers of TDLUs per unit of tissue area ("TDLU count"), median TDLU diameter ("TDLU span"), and number of acini per TDLU ("acini count"). Regression models, stratified by menopausal status and adjusted for potential confounders, were used to assess the associations of TDLU count, median TDLU span and median acini count per TDLU with tertiles of circulating IGFs. Given that mammographic density is associated with both IGF levels and breast cancer risk, we also stratified these associations by mammographic density. Higher IGF-I levels among postmenopausal women and an elevated IGF-I:IGFBP-3 ratio among all women were associated with higher TDLU counts, a marker of decreased lobular involution (P-trend = 0.009 and breast cancer risk. If confirmed in prospective studies with cancer endpoints, these data may suggest that evaluation of IGF signaling and its downstream effects may have value for risk prediction and suggest strategies for breast cancer chemoprevention through inhibition of the IGF system.

    Aim: The goal of our study was to evaluate findings in mammography and sonography in male patients with pathohistologically proven diseases of the breast. Material and Methods: Mammographies and sonographies, which were obtained in 41 male patients in a 6-year period, were retrospectively evaluated in accordance with the BI-RADS trademark classification. Results: Histologically 13 carcinomas, 21 gynecomastias, 3 pseudogynecomastias, 2 epithelial inclusion cysts and 2 other benign lesions were diagnosed. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of mammography in differentiation of benign versus malignant disease were 92%, 89%, 80%, 96% and 90%, respectively. Additional sonography did not change these results. However, sonography increased diagnostic confidence in 18.2% (2/11) of suspicious lesions. Conclusion: In our study the invasive ductal carcinoma of male patients was a predominantly lobulated, ill-defined lesion in mammography and sonography. The differentiation of carcinoma to pseudogynecomastia and diffuse or dendritic gynecomastia was securely feasible. However, we could not reliably distinguish between carcinoma and some benign mass lesions. In cases of mammographically diagnosed masses or unclear mammography, additional sonography should be performed to increase the diagnostic confidence. (orig.)

    Interleukin-10 (IL-10), interleukin-17A (IL-17A) and transforming growth factor α (TGF-α) have been implicated in the progression of breast cancer. However, the diagnostic and prognostic roles of these cytokines in ductal carcinoma remain unclear. The present study therefore aimed to determine the serum levels of IL-10, IL-17 and TGF-α in subjects with benign and malignant breast diseases and to evaluate the clinical significance of these cytokines in ductal carcinoma. Pre-operative serum samples were collected from 378 patients with breast disease and 70 healthy subjects. IL-10, IL-17A and TGF-α levels were measured using ELISA. Serum levels of these cytokine in patients with different breast diseases were evaluated. Furthermore, correlations between levels of these cytokines and the expression of estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) in ductal carcinoma were determined. The results demonstrated that serum levels of IL-10 and IL-17A were significantly increased in subjects with atypical hyperplasia and ductal carcinoma. Furthermore, IL-10 and IL-17A levels were increased in patients with a more serious clinical tumor stage and tumors that were ER - and PR - . Furthermore, high serum levels of TGF-α were associated with HER2 + tumors. A strong positive correlation was identified between TGF-α and IL-17A levels. Therefore, the results of the current study revealed that elevated serum IL-10, IL-17A and TGF-α levels are strongly associated with ductal carcinoma, specifically with tumor stage. High serum levels of IL-10 and IL-17A were also associated with the negative expression of ER and PR in ductal carcinoma, and high serum levels of TGF-α were associated with the positive expression of HER2 in ductal carcinoma. Thus, serum cytokine levels may be measured to identify patients with a poor prognosis who may benefit from more aggressive management and treatment.

All dermatological diseases can in fact occur at this site. There are some specific nipple diseases such as gynaecomastia, congenital abnormalities, hyperplasia, benign tumours and breast cancer. All clinical examinations and laboratory examinations should focus on diagnosis of this type of cancer and its elimination. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    Fibrocystic breast disease has developed a major issue: the breast cancer sequence. Its involvement regarding the increse of breast cancer risk has 2 aspects: it may be either the marker of a prone tissue or a premalignant hystological deffect. Difficult differential diagnosis of benign proliferative breast lession and carcinoma led to the idea of sequency between the two: cancer does not initiate on normal mammary epithelia; it takes several proliferative stages for it to occur. In our series we analized a number of 677 breast surgical procedures where the pathologic examination reveals 115 cases (17%) of coexistence between cancer and fibrocystic breast disease. This aspect has proved to be related to earlier debut of breast cancer, suggesting that epithelial hyperplasia is a risk factor for breast cancer.

    A guanine insertion polymorphism in matrix metalloproteinase-1 promoter (MMP-1 2G) is linked to early onset and aggressiveness in cancer. We determined the role of MMP-1 2G on the level of MMP-1 expression and breast cancer severity in benign breast disease, atypical hyperplasia, invasive and non invasive (in situ) breast cancer. We observed no significant difference in genotype distribution among the different breast disease groups. However, the level of MMP-1 expression was significantly higher in atypical ductal hyperplasia compared to benign breast disease; and in invasive breast cancer compared to in situ breast cancer. MMP-1 2G insertion polymorphism in the invasive group also correlated significantly with the expression of MMP-1 and breast cancer prognostic markers HER2 and P53. PMID:22011282

    Full Text Available Introduction: Benign Osseous metaplasia of the breast is rare, with only a few cases reported in the literature. Here we present a case of benign osseous metaplasia of the breast presenting as a breast lump. Case presentation: 38-year-old previously well woman presented with a one-year history of bilateral breast pain and a left-sided breast lump. Ultrasound and mammography suggested calcified fibroadenoma. An ultrasound-guided true cut biopsy revealed fibrous tissue containing foci of adenosis in the presence of a myoepithelial cell layer. Excision biopsy was performed, and histopathological examination showed bone matrix deposition occupying most of the nodule with peripheral hyalinized tissue but no evidence of malignancy. A diagnosis of benign osseous metaplasia of the breast was made, and the patient recovered well without recurrence after lump excision. Discussion: Only a few cases of osseous metaplasia are reported in the literature. Most reported cases are malignant, such as in fibrosarcoma, malignant mesenchymoma, osteoid sarcoma, osteogenic sarcoma, and osteochondrosarcoma.Very few cases of osseous sarcoma are reported in benign lesions such as fibroadenoma, pleomorphic adenoma, benign mesenchymoma, phyllodes tumor, and amyloid tumor of the breast. Joshi et al. first reported a case of benign osseous metaplasia of the breast presenting as breast lump in an HIV-positive patient [18]. We, therefore, consider this case to be the second case report of benign osseous metaplasia of the breast presenting as a breast lump, but the patient had no chronic illness. Conclusion: A breast lump can be the first presentation of benign osseous metaplasia. Keywords: Benign osseous metaplasia, Breast lump, Case report

    There has been no previous study to classify benign breast lesions in details based on histopathologically confirmed diagnosis in Bayelsa State, Nigeria. This study therefore aims to review all cases of benign breast lesions seen in all the three centres in Bayelsa State with histopathology services over a five year period for a comprehensive baseline data in our community for management, research and education. This is a multicentre retrospective descriptive study based on histopathological diagnosed benign breast lesions from January 2009 to December 2013. Archival results and slides on benign breast lesions were retrieved and analysed using simple statistical methods. A total of 228 benign breast lesions (68.3%) were seen among 334 histopathologically diagnosed breast diseases. The male to female ratio was 19.7:1. Peak age incidence was the third decade (43%) with a mean age of 29.1years. Fibroadenoma was the most common benign breast disease (BBD) accounting for 45.6% of all the cases followed by fibrocystic change (23.1%). The mean ages of fibroadenoma and fibrocystic change were 23.1years and 31.1years respectively. Inflammatory breast lesions constituted 8.3%. We recorded only 2 cases (0.9%) of atypical ductal hyperplasia (ADH) with no case of atypical lobular hyperplasia (ALH) within the study period. Gynaecomastia (4%) was the main male breast lesion in the study. Benign breast diseases are the most common breast lesions in Bayelsa State. Fibroadenoma is the most common lesion followed by fibrocystic change. The incidence of atypical hyperplasia recorded was rather low in the state.

    The associations between emotional personality, proximity and authenticity in patient-physician communication during breast cancer (BC) consultations are rarely considered together in a prospective study. We, therefore, investigated emotional personality/proximity versus authenticity in patient-physician communication in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC). In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated regarding emotional personality, proximity and authenticity in their a patient-physician communication before any diagnostic procedures were carried-out. The emotional personality and the emotional proximity in patient-physician communication was highly significantly positively correlated in the BBD group. The kappa-values for emotional personality versus emotional proximity in the HSS, BBD and BC groups were statistically significant. There was also a highly significant positive correlation between emotional personality and emotional authenticity in the HSS, BBD and BC groups and the kappa values in the HSS, BBD and BC groups were statistically significant. There was a highly significant positive correlation between emotional proximity and emotional authenticity in the BBD group, and the weighted kappa-values in the BBD group were statistically significant. The results of the present study support a powerful link between emotional personality/proximity and emotional authenticity, and provides new information in patient-physician communication in the HSS, BBD and BC groups. This finding is of clinical importance, since during breast disease consultation, barriers to patient-physician communication may be associated with difficulties in early BC diagnosis in the breast cancer diagnostic unit.

    The existence of mammary epithelial stem/progenitor cells has been demonstrated in MUC-1-/ ESA+ subpopulations of breast epithelial cells. However, knowledge about the expression and localization in benign and malignant breast lesions is unknown. Using a double-staining immunohistochemistry method, we investigated MUC-1-/ESA+ cells in 10 normal breast tissues, 49 cases with fibrocystic disease, 40 fibroadenomas, 36 invasive ductal carcinomas and the breast cancer ce...

    Full Text Available Abstract Background Caveolin-1 is thought to have an important impact on both signal transduction and mediation of intracellular processes. Furthermore, it has been suggested that Caveolin-1 may contribute to certain steps of carcinogenesis in various types of cancer. We examined the potential clinical relevance of Caveolin-1 in normal, benign and malignant breast tissue specimens. Methods Using tissue microarray (TMA technology cases of invasive breast cancer, DCIS, benign breast disease (i.e. fibroadenoma, sclerosing adenosis, ductal hyperplasia and radial scar and normal breast tissue were evaluated for Caveolin-1 expression. Immunohistochemical staining with an anti-Caveolin-1-antibody was performed. Staining intensity was quantified semiquantitatively. In invasive lesions staining results were correlated with clinical and pathological data. Results No Caveolin-1 expression was observed in epithelial cells of normal breast tissue (n = 5, benign breast disease (n = 295 and DCIS (n = 108. However, Caveolin-1 expression was found in 32 of 109 cases of invasive breast carcinomas (29.4%. Caveolin-1 expression in invasive breast cancer could neither be correlated with survival parameters such as overall or disease-free survival nor with established clinical and pathological markers. Conclusion In this study we demonstrated expression of Caveolin-1 in one third of invasive breast cancers. A significant increase in Caveolin-1 expression was observed comparing invasive breast cancer to both benign breast tissue and non-invasive breast cancer. Since inhibitors of Caveolin-1 signalling are available, targeting Caveolin-1 in breast cancer may represent a potential option for future breast cancer treatment.

    Early breast cancer detection is important for intervention and prognosis. Advances in treatment and outcome require diagnostic tools with highly positive predictive value. To study the potential role of quantitative MRI (qMRI) using T1/T2 ratios to differentiate benign from malignant breast lesions. A cross-sectional study of 69 women with 69 known or suspicious breast lesions were scanned with mixed-turbo spin echo pulse sequence. Patients were grouped according to histopathological assessment of disease stage: untreated malignant tumor, treated malignancy and benign disease. Elevated T1/T2 means were observed for biopsy-proven malignant lesions and for malignant lesions treated prior to qMRI with chemotherapy and/or radiation, as compared with benign lesions. The qMRI-obtained T1/T2 ratios correlated with histopathology. Analysis revealed correlation between elevated T1/T2 ratio and disease stage. This could provide valuable complementary information on tissue properties as an additional diagnostic tool.

    The relation between hopelessness/helplessness versus the Beck Depression Inventory (BDI) in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared in a prospective study before. We, therefore, investigated hopelessness and helplessness versus the BDI in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness versus the BDI before any diagnostic procedures were carried out. In the self-rating score (SRS), the hopelessness and the helplessness versus the BDI were highly significantly positively correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa values for hopelessness and helplessness versus the BDI in the HSS, BBD and BC groups were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) in the hopelessness versus the BDI in the BBD and BC groups and in the ERS in helplessness versus the BDI in the HSS and BBD groups. The unweighted kappa values in the ERS for hopelessness versus the BDI in the HSS and BBD groups were statistically highly significant and the unweighted kappa values in the ERS for helplessness versus the BDI in the BBD and BC groups were statistically significant. The results of this study support a powerful link between hopelessness and helplessness versus BDI in the self-rating and examiner-rating. This finding is of clinical importance since, in the breast cancer diagnostic unit, the patients with hopelessness/helplessness characteristics and high BDI score might be associated with a difficulty and delay in reaching BC diagnosis.

    The relation between scoring for hopelessness/helplessness and the Montgomery-Asberg Depression Rating Scale (MADRS) in healthy study subjects (HSS) and in patients with benign breast disease (BBD) and breast cancer (BC) has not been compared in a prospective study. We, therefore, investigated hopelessness and helplessness scores versus the MADRS in 115 patients. In the Kuopio Breast Cancer Study, 115 women with breast symptoms were evaluated for hopelessness and helplessness, and for the MADRS before any diagnostic procedures were carried out. In the self-rating score (SRS), hopelessness/helplessness versus the MADRS were highly significantly positively correlated in the HSS, BBD and BC groups. In the SRS, the weighted kappa values for hopelessness/helplessness versus the MADRS in the HSS, BBD and BC groups were also statistically significant. There was also a significant positive correlation in the examiner-rating score (ERS) for hopelessness versus the MADRS in the HSS, BBD and BC groups and for helplessness versus the MADRS in the HSS, BBD and BC groups. The unweighted kappa values in the ERS for hopelessness versus the MADRS were statistically highly significant for the HSS, BBD and BC groups and those for helplessness versus the MADRS in the HSS and BBD groups were statistically significant. A new finding with clinical relevance in the present work is the agreement between hopelessness/helplessness scores and MADRS in the SRS and ERS. In the breast cancer diagnostic unit, the identification of hopeless/helpless persons is essential in suicide prevention and it is important to assess and treat hopelessness/helplessness even though an individual may report few depressive symptoms.

    Full Text Available Background & Objectives: Breast problems, benign or malignant are common in occurrence worldwide. Breast problems can present themselves in a number of ways like breast pain, nipple discharge, cystic lesions and more commonly a lump. Breast diseases are under reported and cancer is one of the leading causes of mortality in women. This prospective study was undertaken with an aim to study the profile of various breast diseases in eastern Nepal.Materials & Methods:  This is a prospective study of women with breast diseases conducted from March 2011 to February 2012. Inclusion criteria were women irrespective of age with breast diseases with or without complaints. Exclusion criteria were women having breast abscess and mammary fistula.Results: Out of 125 breast diseases 39 cases (31% had malignancy and 86 cases (69% had BBD. The overall mean age for BBD was 25.9 years, with range of 10-60 years. The mean age for malignant breast diseases was 45.6 years, with range of 28-67 years. All of the cases had breast lump as their presenting complaints whether they came out benign or malignant. 52.8% had no significant pain associated with lump; in malignant cases 35.8% had pain associated with lump. In benign cases 68.7% had no perceptible change in lump size. On ultrasound scan, 69% of the lesions were designated benign compared to 31% malignant features. FNAC resulted in 68% lesions to be classified as of benign nature and 32% as malignant /suspicious malignancy.Conclusion: BBD constituted 69% of breast diseases, and mostly fibroadenoma and FCC/FCD and commonest malignant lesion was infiltrating ductal carcinoma. The BBD peaked at the age of 21-30 years.

    MicroRNAs are endogenous, small non-coding RNAs that control gene expression by directing their target mRNAs for degradation and/or posttranscriptional repression. Abnormal expression of microRNAs is thought to contribute to the development and progression of cancer. A history of benign breast disease (BBD) is associated with increased risk of subsequent breast cancer. However, no large-scale study has examined the association between microRNA expression in BBD tissue and risk of subsequent invasive breast cancer (IBC). We conducted discovery and validation case-control studies nested in a cohort of 15,395 women diagnosed with BBD in a large health plan between 1971 and 2006 and followed to mid-2015. Cases were women with BBD who developed subsequent IBC; controls were matched 1:1 to cases on age, age at diagnosis of BBD, and duration of plan membership. The discovery stage (316 case-control pairs) entailed use of the Illumina MicroRNA Expression Profiling Assay (in duplicate) to identify breast cancer-associated microRNAs. MicroRNAs identified at this stage were ranked by the strength of the correlation between Illumina array and quantitative PCR results for 15 case-control pairs. The top ranked 14 microRNAs entered the validation stage (165 case-control pairs) which was conducted using quantitative PCR (in triplicate). In both stages, linear regression was used to evaluate the association between the mean expression level of each microRNA (response variable) and case-control status (independent variable); paired t-tests were also used in the validation stage. None of the 14 validation stage microRNAs was associated with breast cancer risk. The results of this study suggest that microRNA expression in benign breast tissue does not influence the risk of subsequent IBC.

    Purpose: To study the CT signs of breast diseases, and discuss the value of CT in the diagnosis of breast cancer and the axillary lymph node (LN) metastases. Materials and methods: Fifty three cases were reported, including breast cancer 30 cases and benign diseases 23 cases. CT were performed in all patients, 44 also had mammography examination. Results: (1) The CT appearance of breast cancer: round or irregular mass, spiculate border, duct retraction, involved Cooper's ligament, deformed adipose space etc. Benign hyperplasia: Irregular mass and symmetrical thickening of breast glands. Cystic hyperplasia: typically multiple, round, liquid-density mass. (2) CT was comparable to mammography in terms of differential diagnosis, however with breast mass located near the axilla or for evaluation of the thoracic wall. CT was superior to mammography. CT was also helpful in detecting LN metastases. Conclusion: CT is valuable in detecting and differentiating breast diseases as well as in the diagnosis of LN metastases

    Vibro-acoustography (VA) is a newly developed imaging technology that is based on low-frequency vibrations induced in the object by the radiation force of ultrasound. VA is sensitive to the dynamic characteristics of tissue. Here, we evaluate the performance of VA in identifying benign lesions and compare the results to those of mammography. An integrated mammography-VA system designed for in vivo breast imaging was tested on a group of female volunteers, age ≥ 18 years, with suspected breast lesions based on clinical examination. A set of VA scans was acquired after each corresponding mammography. Most lesions were classified as benign based on their histological results. However, in 4 cases, initial diagnosis based on clinical imaging determined that the lesions were cysts. These cysts were aspirated with needle aspiration and disappeared completely under direct ultrasound visualization. Therefore, no biopsies were performed on these cases and lesions were classified as benign based on clinical findings per clinical standards. To define the VA characteristics of benign breast masses, we adopted the features that are normally attributed to such masses in mammography. In a blinded assessment, three radiologists evaluated the VA images independently. The diagnostic accuracy of VA for detection of benign lesions was assessed by comparing the reviewers’ evaluations with clinical data. Out of a total 29 benign lesions in the group, the reviewers were able to locate all lesions on VA images and mammography, 100% with (95% confidence interval (CI): 88% to 100%). Two reviewers were also able to correctly classify 83% (95% CI: 65% to 92%), and the third reviewer 86% (95% CI: 65% to 95%) of lesions, as benign on VA images and 86% (95% CI: 69% to 95%) on mammography. The results suggest that the mammographic characteristics of benign lesion may also be used to identify such lesions in VA. Furthermore, the results show the ability of VA to detect benign breast

    Hysterectomy is one of the most common gynaecological surgical procedures performed but there appears to be a decline in the performance of this procedure in Ireland in recent times. We set out to establish the extent of the decline of hysterectomy and to explore possible explanations. Data for hysterectomy for benign disease from Ireland was obtained from the Hospital In-Patient Enquiry Scheme (HIPE) section of the Economic and Social Research Institute for the years 1999 to 2006. The total number of hysterectomies performed for benign disease showed a consistent decline during this time. There was a 36% reduction in the number of abdominal hysterectomy procedures performed.

    Full Text Available BACKGROUND AND OBJECTIVES The breast is the essential symbol of womanhood to society and to the woman herself. Subjected every month to the onslaught of ovarian, adrenal, pituitary and thyroid hormones in tandem with the uterus, the very histological architecture of the breast changes sequentially. With the recent importance given to early diagnosis of cancer of the breast and its early detection by both the patient and her physician, more benign conditions are likely to be detected than earlier. The objective of our review is to find out the incidence of benign breast lump above 40 years of age in females attending our hospital. METHODS AND MATERIALS 130 patients presenting to the outpatient department of KAPV Medical College with breast lump were included in this comprehensive study. A detailed history regarding the duration and nature of the complaints, family history pertaining to breast or ovarian cancers, risk factors such as oral contraceptive use, parity, lactation, etc. was elicited. A thorough clinical examination was performed. RESULTS Of 24 cases of fibroadenoma, all were operated upon by excision. Of 38 patients with fibroadenosis, 30 patients managed conservatively and surgery for 8 patients where the diagnosis was doubtful. Abscesses were incised and drained under antibiotic cover for 3 patients. 8 cases of breast cyst were managed by aspiration. TB mastitis was confirmed by excisional biopsy and followed up by antituberculous therapy with regular follow up after 6 months. Healed lesions were found to be associated with improved general condition of the patients. Lipoma and sebaceous cyst were managed by excision biopsy. CONCLUSION Benign breast diseases were found to be common in woman above 40 years old in contrast to normal teaching, which says they are common in younger age groups. Fibroadenosis was the commonest benign disease closely followed by fibroadenoma. Fibroadenosis was mostly managed conservatively. Excision biopsy

    With monoclonal antibody D-274, raised against guinea pig milk fat globule membrane, the distribution of mucinlike glycoproteins of Mrs greater than or equal to 400,000 was determined in benign fibrocystic disease and infiltrating duct carcinoma of the human breast. These glycoproteins, called collectively PAS-I, were detected in 19 out of 20 cases of benign fibrocystic disease and in at least 26 out of 47 cases of infiltrating duct carcinoma. PAS-I was concentrated on luminal surfaces of ducts and alveoli in morphologically differentiated regions of the tumors. In areas where the glandular nature of the tissue was less evident in infiltrating duct carcinoma, the PAS-I determinant recognized by antibody D-274 was present on irregular luminal surfaces and in the cytoplasm. There was a negative correlation between the short-term recurrence (less than 2 years) of infiltrating duct carcinoma and the detection of strong positive staining with antibody D-274. The results are discussed with reference to recent studies on PAS-I in human breast tissue using monoclonal antibodies raised against human milk fat globule membrane.

    c-kit (CD117) is a transmembrane tyrosine kinase that acts as a type III receptor for mast cell growth factor. In recent years, the role of c-kit in the development of preinvasive and invasive breast carcinomas has been investigated. The aim of our study was to detect c-kit expression in the entire spectrum of common benign and malignant breast lesions in correlation with a well-studied myoepithelial or stem-cell like marker (p63). We evaluated 270 cases of benign and malignant breast lesions including fibrocystic disease, fibroadenoma, sclerosing adenosis, atypical ductal hyperplasia, ductal/lobular carcinoma in situ, and ductal/lobular/mixed type carcinoma. C-kit staining was evaluated in the cytoplasm/cell membrane in epithelial and myoepithelial cells and p63 in the nuclei of myoepithelial cells. c-kit was highly expressed (85.3%) in benign lesions (fibrocystic disease, sclerosing adenosis, fibroadenoma), and p63 expression was 95.5% in the aforementioned lesions. c-kit distribution in preinvasive and invasive lesions was as follows: ductal/lobular carcinoma in-situ, 43%/35%; ductal/lobular carcinoma, 36%/39%; and mixed type carcinoma, 20%. c-kit was highly expressed in myofibroblast/fibroblast cells only in grade III ductal/lobular carcinomas. c-kit was totally absent in stromal cells in benign lesions and in situ carcinomas whereas expression was weak in grade I and II carcinomas. Combined overexpression of c-kit and p63 is indicative of benign breast lesions. In contrast, there is reduced expression of c-kit in in situ and invasive breast carcinomas, with simultaneous overexpression in the stromal cells. This suggests that c-kit may play a role in breast cancer progression.

    Full Text Available BACKGROUND Despite the fact that in majority of cases the initial symptom of benign breast disease is a lump, which can be easily detected by the patient herself by self-examination they generally present at a very late stage and this poses a great difficulty in their management. Early and appropriate diagnosis of breast disease is of utmost importance. AIM The aim of the study was to find out the relative frequency and commonest site of occurrence of benign breast disorder and their relationship with age, parity, menstrual cycle, and socio-economic status and also to find out the accuracy of investigative procedures in their diagnosis. DESIGN This is a cross sectional, interventional. Hospital based study. MATERIALS AND METHOD This study was done in 58 female patients in the age group 10 yrs. to 55 yrs. presenting with clinically benign breast lumps randomly chosen from outpatient department and indoor wards of The Calcutta Medical Research Institute, Kolkata. After taking an accurate history and proper clinical examination these patients were sequentially studied by radiological methods (Ultrasonography and mammography, fine needle aspiration cytology (FNAC and histopathology of removed specimen. Patients were enquired about their age, chief complaints, menstrual history, and use of oral pill, marital status, parity, lactation and socioeconomic status. RESULTS 79% of the benign breast lumps were found to be between 10–35 years, Fibro adenoma being the commonest one (41.38% and fibrocystic disease the second most common (29.31%. Breast lump were more common among unmarried and nulliparous females (48.27%, commonest site being upper and outer quadrant (38.8%. 69% patients were associated with an abnormal menstrual status. 76% of the cases were accurately diagnosed by clinical examination, 70% by mammography, 88% by FNAC and 84% by ultrasonography. CONCLUSION This clinicopathological study of benign breast lump is a small endeavour on our part

    Benign intraductal papilloma is a rare lesion in the male breast. The authors report the occurrence of an intraductal papilloma in a male with more than a ten-year history of phenothiazine therapy (Mellaril and Prolixin). Phenothiazines have been demonstrated to cause elevated serum prolactin levels. The literature regarding the relationship between prolactin and mammary tumors in rodents and in humans remains controversial. The occurrence of this rare male breast tumor in the setting of chronic phenothiazine therapy raises further questions as to the role of prolactin in the development of mammary tumors.

    Full Text Available Benign breast lesions (BBL includes a wide variety of histologic entities, which have been broadly classified into non-proliferative lesions, proliferative lesions without atypia, and hyperplasia with atypia. With the increased use of mammography, more benign lesions are being detected, and in order to estimate the risk of breast cancer for specific histologic categories is of great importance to guide clinical management. Women with proliferative lesions without atypia are at slightly increased risk of subsequent breast cancer, whereas women with proliferative lesions with atypia have a higher risk. The risk is 1.5- 2-fold in women with proliferative lesions without atypia, 4-5-fold in women with proliferative lesions with atypia, and 8-10 fold in women with ductal carcinoma in situ. Age at diagnosis of BBL, menopausal status, family history of breast cancer in a first-degree relative, and time since BBL diagnosis on risk of breast cancer are important for risk evaluation.

    Most described male breast lesions, such as gynecomastia, are benign. The overall incidence of male breast cancer is less than 3%. Like women, common presentations of male breast diseases are palpable lumps or tenderness. Physical examination, mammography and ultrasound are generally used for work-up of breast diseases in both women and men. However, men do not undergo screening mammograms; all male patients are examined in symptomatic cases only. Therefore, all male breast examinations are diagnostic, whereas the majority of the examinations for women are for screening purpose. The differentiation between benign and malignant breast lesions is important, especially for men, because the reported prognosis of male breast cancer is poor due to delayed diagnosis. In this article, we review the spectrum of male breast diseases, from benign to malignant, and illustrate their ultrasonographic and mammographic imaging features.

    Radiation therapy of benign diseases represent a wide panel of indications. Some indications are clearly identified as treatment of arteriovenous malformations (AVM), hyperthyroid ophthalmopathy, postoperative heterotopic bone formations or keloid scars. Some indications are under evaluation as complications induced by neo-vessels of age-related macular degeneration or coronary restenosis after angioplasty. Some indications remain controversial with poor evidence of efficiency as treatment of bursitis, tendinitis or Dupuytren's disease. Some indications are now obsolete such as warts, or contra-indicated as treatment of infant and children. (authors)

In this study there were a total of 307 breast biopsies and mastectomy specimens of which 67 were inflammatory, 166 benign and 74 malignant. Fibroadenoma was the commonest (35.179%) followed by invasive ductal carcinoma (21.824%),fibrocystic disease (16.286%), breast abscess (7.166%) and chronic mastitis (7.817%). Fibroadenoma was common in second decade and infiltrative ductal carcinoma in fifth decade. Breast carcinoma occurs at a younger age group in (Karachi - Pakistan) than in western countries. (author)

    Surgical management of thyroid diseases (BTDs) has been a topic of interest and confusion for many years. Almost 80% of thyroidectomies at an average endocrine surgical unit are carried out for BTDs.Resistance to surgical intervention in BTDs has been based on the belief that increased complication rate is inherent in its use, this is despite thepotential advatages in terms of confirming the benign nature of the lesion, controlling the disease, and relieving of local symptoms of large neck mass. Benign thyroid diseases are more likely to occur in middle-aged woman living in iodine deficient areas, or have a family history of goiter, or in patients taking iodine-containig drugs, like amoidarone, or in patients with previous history of x-ray exposure. However, the physician must be carefull in making the diagnosis of BTDsin patients of extremes of age or in presence of positive history of radiation, or in patients with family history of thyroid or colon cancer . In this atricle we will review the etiology,epidemiology , diagonastic methodologiesand the recent trends in the sugical and medical mangement of BTDs. (author)

    Burns and chronic inflammation are well-known circumstances in which malignant transformation may occur during wound healing. There are many reports of malignancies developing from a burn scar; however, there are only a few reports of malignancy arising from chronic inflammation or from the skin of a surgical scar following excision of a benign mass, in any part of the body. There are only twelve reported cases of breast cancer developing from a surgical scar, moreover, there have been no reports in the last 30 years. This case is a recent example of breast cancer developing in a surgical scar that showed subtle changes on sequential sonograms. The imaging findings of this case were subtle but the mass that had been shrinking developed an angular margin in one region. These findings, along with the penetrating vascularity revealed on Doppler, prompted us to proceed to a biopsy of the lesion. It was of critical importance to compare the size and the shape of the lesion with previous ultrasounds in order to exclude malignancy in any iatrogenically altered lesion. Based on this case, we conclude that whenever a subtle change is detected, at a surgical site, a biopsy should be performed. Breast cancer developing from a surgical scar is rare; this type of malignancy has been reported in only 12 cases to date. Herein, we report on a 52-year-old female who developed infiltrating ductal carcinoma in a surgical scar following excision of a benign mass. Two years previously, the patient underwent surgery and radiotherapy for invasive ductal carcinoma of the contralateral breast. The initial appearance of the scar was similar to fat necrosis; it was observed to be progressively shrinking on follow-up sonography. On the two year follow-up ultrasound, the appearance changed, an angular margin and vascularity at the periphery of the scar were noted. A biopsy and subsequent excision of the scar were performed; the diagnosis of infiltrating ductal carcinoma of the scar was

    X-ray should only be applied when other forms of treatment of good-natured diseases do not provide equally good results. One should note that somatic lesion should be completely avoided and genetic lesion avoided to the greatest probability. One can distinguish according to ones aims between inflammation irradiation, pain irradiation, stimulation therapy and functional therapy. An indication for inflammation irradiation can be post-operative parotitis, furuncle in the face, mastitis puerperalis, panaritium ossale, recurrent sudoriparouns abscesses and repelling reactions after transplanting organs. Pain irradiation is indicated with degenerative diseases of the skeleton system. A further possible application is radiotherapy of hypotrophic processes and benign tumours. Functional radiotherapy is indicated with hyperendocrinism, neurovegetative disorders and allergies. (MG) [de

    Breast cancer has emerged as a leading site of cancer among women in India. Fine needle aspiration cytology (FNAC) has been routinely applied in assessment of breast lesions. Cytological evaluation in breast lesions is subjective with a "gray zone" of 6.9-20%. Quantitative evaluation of nuclear size, shape, texture, and density parameters by morphometry can be of diagnostic help in breast tumor. To apply nuclear morphometry on cytological breast aspirates and assess its role in differentiating between benign and malignant breast lesions with derivation of suitable cut-off values between the two groups. The present study was a descriptive cross-sectional hospital-based study of nuclear morphometric parameters of benign and malignant cases. The study included 50 benign breast disease (BBD), 8 atypical ductal hyperplasia (ADH), and 64 carcinoma cases. Image analysis was performed on Papanicolaou-stained FNAC slides by Nikon Imaging Software (NIS)-Elements Advanced Research software (Version 4.00). Nuclear morphometric parameters analyzed included 5 nuclear size, 2 shape, 4 texture, and 2 density parameters. Nuclear morphometry could differentiate between benign and malignant aspirates with a gradually increasing nuclear size parameters from BBD to ADH to carcinoma. Cut-off values of 31.93 μm 2 , 6.325 μm, 5.865 μm, 7.855 μm, and 21.55 μm for mean nuclear area, equivalent diameter, minimum feret, maximum ferret, and perimeter, respectively, were derived between benign and malignant cases, which could correctly classify 7 out of 8 ADH cases. Nuclear morphometry is a highly objective tool that could be used to supplement FNAC in differentiating benign from malignant lesions, with an important role in cases with diagnostic dilemma.

    To assess the value and problems of fat-suppressed dynamic MR imaging in differentiating between benign and malignant lesions. In twenty-nine patients who underwent excisional biopsy or surgical resection, fat-suppressed dynamic MR imaging was performed with a 0.5 T superconducting magnet. Pre- and post-contrast 3D-spoiled gradient echo sequences were employed with fat suppression. We calculated and evaluated the contrast-to-noise ratio (CNR) and contrast enhancement ratio (CER) at each contrast determination time (CDT), which is the intermediate time in the scan. Time intensity curves of CNR showed no statistically significant difference between cancers and other benign lesions. The difference in CER between malignant and benign disease was highly significant (p=0.006) at CDT 45 sec., but there was great overlap in the time intensity curve of CER after CDT 45 sec. When we attempt to differentiate malignant from benign breast lesions by dynamic MR imaging, comparison of CNR is impertinent, and we should evaluate the differential diagnosis of cancer versus benign lesions by means of CER at CDT points of about 45 sec.

    1. In Berlin (West), X-ray therapy was applied during the year 1973 in 18 hospitals and by 33 practicing physicians. The 3rd quarter of the year 1973 was taken as basis for the frequency of therapeutic X-ray application. From a total of 15912 patients, 9432 were X-rayed on account of malignant diseases, 6480 because of benigne diseases. This number definitely surpasses the number of cases treated in Munich by X-ray therapy. In Berlin, this might be connected to the age structure. 2. Utilizing the quotations and calculations put down in the report about the effect of atomic radiation by the Scientific Committee of the United Nations, and the values quoted for gonadal doses in the literature, a total-GSD-value of 0.82 +- 0.2 mrem/a was calculated for hospitals and practicing physicians in Berlin. In spite of higher frequencies, this value is approximately of the same order of magnitude as the values calculated for Munich for the year 1971 by I. and H.P. Schmelz. 3. The total-GSD-value for the population of the Federal Republic of Germany resulting from artificial radiation exposure during 1976 is reported to be approximately 60 mrem. Thus, the GSD-value for the X-ray therapy of benign diseases lies approximately at 1.3% and should be of minor significance for radiation-hygienic reflections. 4. Of primary concern is still the radiation exposure to individual patients. Because of possible secondary effects, X-ray therapy for keloids and hemangiomas in infancy and youth are of particular significance. For this reason, its proportion to GSD is also in Berlin relatively large. (orig.) [de

    Purpose: the numbers of patients with nonmalignant diseases referred for radiation therapy had to be evaluated for the last 4 years. Patients and methods: in the years 2002, 2004, and 2005 radiation therapy was performed in 61, 40, and 26 patients, respectively. Regularly, more women than men were treated, median age annually was 57, 54, and 55 years, respectively (table 1). The radiotherapy scheme was not modified within the evaluated period. Results: the proportion of nonmalignant diseases among all patients treated decreased from 4.7% in 2002 to 3.3% in 2004 and 2.2% in 2005, respectively. A shift was noticed toward the treatment of four main diseases (endocrine orbitopathy, prevention of heterotopic ossification, meningeoma, tendinitis, table 2). The number of referring physicians decreased from 19 to six. Conclusion: due to administrative restrictions for treatment in hospitals, budget restrictions in private practices and lasting, insufficient revenues for radiotherapy in nonmalignant diseases, radiation therapy for the entire group of benign diseases is endangered.

    The study reports enhanced Fe, Cu, and Zn contents in breast tissues, a probable risk factor of breast cancer in females. Forty-one formalin-fixed breast tissues were analyzed using atomic absorption spectrophotometry. Twenty malignant, six adjacent to malignant and 15 benign tissues samples were investigated. The malignant tissues samples were of grade 11 and type invasive ductal carcinoma. The quantitative comparison between the elemental levels measured in the two types of specimen (benign and malignant) tissues (removed after surgery) suggests significant elevation of these metals (Fe, Cu, and Zn) in the malignant tissue. The specimens were collected just after mastectomy of women aged 19 to 59 years from the hospitals of Islamabad and Rawalpindi, Pakistan. Most of the patients belong to urban areas of Pakistan. Findings of study depict that these elements have a promising role in the initiation and development of carcinoma as consistent pattern of elevation for Fe, Cu, and Zn was observed. The results showed the excessive accumulation of Fe (229 ± 121 mg/L) in malignant breast tissue samples of patients (p factor of breast cancer. In order to validate our method of analysis, certified reference material muscle tissue lyophilized (IAEA) MA-M-2/TM was analyzed for metal studied. Determined concentrations were quite in good agreement with certified levels. Asymmetric concentration distribution for Fe, Cu, and Zn was observed in both malignant and benign tissue samples.

    Cases of radiation therapy for benign diseases have diminished in number because of recent alternative methods and knowledge about radiation carcinogenesis. In contrast to this tendency, our cases of benign diseases have recently increased. The facts made us reconsider today's radiation therapy of benign diseases. We reviewed 349 patients who were diagnosed as having benign tumors or non-neoplastic conditions and treated by radiation therapy in the past sixteen years. Analyzed items were the annual transition of treatment number, sorts of diseases, patients' age and sex, and the goal of therapy. Of all radiation therapy patients, benign diseases account for 9.26%. The annual percentages were 0.5%, 6.0%, 11.2% and 13.7% at intervals of five years since 1982. The majority was 246 post-operative irradiation for keloids (71%) and 41 pituitary adenomas (12%). Compared with malignant tumors, benign disease patients were statistically younger and female-dominant. Applications of radiation therapy in keloids and pituitary adenomas had definite goals, but were unclear in other rare diseases. Benign diseases should be treated by radiation therapy as the second or third option, provided the patients have serious symptoms and their diseases do not respond to other modalities. It seems to be widely accepted that favorite cases such as keloids and pituitary adenomas are treated by radiation therapy. But, optimal radiation therapies for other rare benign diseases have not been established. Therefore, the building of databases on radiation therapy on benign diseases should be pursued. Since benign disease patients were young and female-dominant and had many remaining years, their carcinogenicity potential should be considered. (author)

    Objective: To investigate the value of apparent diffusion coefficient (ADC) of diffusion- weighted magnetic resonance imaging (DW-MRI) in distinguishing benign from malignant breast lesions. Methods: ADC in 26 normal breasts, 24 malignant breast lesions, and 30 benign breast lesions confirmed by operation and pathology were calculated, respectively, and their differentiations in statistics were compared. The differentiations of different ADCs (b=1000-0, 500-0, 1000-500 s/mm 2 ) were also compared. EPI (TR 2900 ms, TE 84 ms, thickness 5 mm) was used in order to acquire the imaging. Results: There were significant differences among the ADC values of normal breast tissue, benign, and malignant lesions. The ADC of malignant lesions was lower than those of normal breast tissue and benign lesions, and the ADC of benign lesions was lower than that of normal breast tissue. There were significant differences among the ADC value of b=1000-0, 1000-500, and 500-0 s/mm 2 . The lower the b value, the higher the ADC. The sensitivity and specificity of ADC for the diagnosis of malignant lesion were 64% and 96.7% if the upper bound of 95% confidence interval was set as a differential level. Conclusion: The differentiation of benign from malignant breast lesions by ADC is applicable, although the sensitivity is low, the specificity is high. (authors)

    The objective of this study was to determine how age and psychological characteristics assessed prior to diagnosis could predict psychological distress in outpatients immediately after disclosure of their diagnosis. This is a longitudinal and prospective study, and participants were breast cancer patients and patients with benign breast problems (BBP). Patients were asked to complete questionnaires to determine levels of the following: trait anxiety (State-Trait Anxiety Inventory), negative emotional suppression (Courtauld Emotional Control Scale), life stress events (Life Experiences Survey), and psychological distress (Profile of Mood Status) prior to diagnosis. They were asked to complete a questionnaire measuring psychological distress after being told their diagnosis. We analyzed a total of 38 women diagnosed with breast cancer and 95 women diagnosed with a BBP. A two-way analysis of variance (prior to, after diagnosis × cancer, benign) showed that psychological distress after diagnosis among breast cancer patients was significantly higher than in patients with a BBP. The multiple regression model accounted for a significant amount of variance in the breast cancer group (model adjusted R(2) = 0.545, p psychological distress after diagnosis, and might have prospects as a screening method for psychologically vulnerable women.

    Various male breast diseases have characteristic mammographic appearances that can be correlated with their pathologic diagnoses. Male breast cancer is usually subareolar and eccentric to the nipple. Margins of the lesions are more frequently well defined, and calcifications are rarer and coarser than those occurring in female breast cancer. Gynecomastia usually appears as a fan-shaped density emanating from the nipple, gradually blending into surrounding fat. It may have prominent extensions into surrounding fat and, in some cases, an appearance similar to that of a heterogeneously dense female breast. Although there are characteristic mammographic features that allow breast cancer in men to be recognized, there is substantial overlap between these features and the mammographic appearance of benign nodular lesions. The mammographic appearance of gynecomastia is not similar to that of male breast cancer, but in rare cases, it can mask malignancy. Gynecomastia can be mimicked by chronic inflammation. All mammographically lucent lesions of the male breast appear to be benign, similar to such lesions in the female breast.

    Previous studies and biological mechanisms of carcinogenesis suggest that the steroid receptor content of benign breast epithelium may be related to breast cancer risk. The objective in this study was to compare the levels of estrogen receptor-α (ER) and progesterone receptor (PR) in nonneoplastic breast epithelium between breast cancer cases and biopsy controls. Between 1995 and 1997 at two sites (Women's College Hospital in Toronto and Kingston General Hospital), 667 women who were scheduled for diagnostic excisional breast biopsies completed a questionnaire providing personal information and agreed to allow analysis of routinely resected tissue. Histological slides with nonneoplastic epithelium were available for 101 cancer cases and 200 biopsy controls in Toronto and for 105 cancer cases and 119 controls in Kingston. Nonneoplastic epithelium was examined with immunohistochemical assays to determine the percent of epithelial cells staining for ER and PR. Unconditional logistic regression was used to calculate odds ratios (OR) stratified by study site. The ER content of nonneoplastic tissue was higher in cases than biopsy controls in unadjusted analyses; after adjustment for age, however, a weak association remained in only one of the study sites. After adjustment for age, the PR content of nonneoplastic tissue was slightly lower in breast cancer cases than controls in one study site. Furthermore, this inverse association was confined to women with PR negative breast cancer in comparison to the controls. No interaction between ER and PR content of nonneoplastic tissue was observed in relation to the odds of having breast cancer. The results of this study are consistent with only a slight indication of increased ER levels in nonneoplastic tissue in breast cancer cases relative to controls. This study contributes to the understanding of breast cancer by examining both ER and PR in nonneoplastic tissue. Limitations remain, however, such as the necessity of

    Surgery has been the classic treatment of choice for benign cystic diseases, including lymphatic malformation, ranula, branchial cleft cyst, thyroglossal duct cyst, thyroid cyst, parathyroid cyst, and lymphocele. However, surgery is associated with a tendency toward recurrence and may be accompanied by various complications, such as nerve injuries, vascular injuries, and scar formation. Therefore, sclerotherapy using various agents has been applied successfully to treatment of benign cystic diseases in the neck.

    To evaluate the accuracy of benign core biopsy of probably benign breast lesions (category 3) 2 cm or larger on the basis of excisional biopsy and long-term follow-up. We retrospectively reviewed 146 category 3 lesions in 146 patients 2 cm or larger which were diagnosed as benign by ultrasound (US)-guided core biopsy. Patients were initially diagnosed as benign at core needle biopsy and then followed up with excisional biopsy (surgical excision, n=91; US-guided vacuum assisted excision, n=35) or breast ultrasonography (n=20). Of the 126 patients who underwent surgical excision or US-guided vacuum-assisted excision, 114 patients were diagnosed with benign lesions, 10 patients with borderline lesions (benign phyllodes tumor), and two patients with malignant phyllodes tumors. The probabilities of lesions being benign, borderline and malignant were 91.8% (134/146), 6.8% (10/146), and 1.4% (2/146), respectively. Of 13 patients who had growing masses on follow-up ultrasonography, three (23.1%) were non-benign (two benign phyllodes tumors and one malignant phyllodes tumor). US-guided core needle biopsy of probably benign breast mass 2 cm or larger was accurate (98.6%) enough to rule out malignancy. But, it was difficult to rule out borderline lesions even when they were diagnosed as benign.

    Objectives To perform a meta-analysis assessing the ability of shear wave elastography (SWE) to identify malignant breast masses. Methods PubMed, the Cochrane Library, and the ISI Web of Knowledge were searched for studies evaluating the accuracy of SWE for identifying malignant breast masses. The diagnostic accuracy of SWE was evaluated according to sensitivity, specificity, and hierarchical summary receiver operating characteristic (HSROC) curves. An analysis was also performed according to the SWE mode used: supersonic shear imaging (SSI) and the acoustic radiation force impulse (ARFI) technique. The clinical utility of SWE for identifying malignant breast masses was evaluated using analysis of Fagan plot. Results A total of 9 studies, including 1888 women and 2000 breast masses, were analyzed. Summary sensitivities and specificities were 0.91 (95% confidence interval [CI], 0.88–0.94) and 0.82 (95% CI, 0.75–0.87) by SSI and 0.89 (95% CI, 0.81–0.94) and 0.91 (95% CI, 0.84–0.95) by ARFI, respectively. The HSROCs for SSI and ARFI were 0.92 (95% CI, 0.90–0.94) and 0.96 (95% CI, 0.93–0.97), respectively. SSI and ARFI were both very informative, with probabilities of 83% and 91%, respectively, for correctly differentiating between benign and malignant breast masses following a “positive” measurement (over the threshold value) and probabilities of disease as low as 10% and 11%, respectively, following a “negative” measurement (below the threshold value) when the pre-test probability was 50%. Conclusions SWE could be used as a good identification tool for the classification of breast masses. PMID:24204613

An analysis was also performed according to the SWE mode used: supersonic shear imaging (SSI) and the acoustic radiation force impulse (ARFI) technique. The clinical utility of SWE for identifying malignant breast masses was evaluated using analysis of Fagan plot. A total of 9 studies, including 1888 women and 2000 breast masses, were analyzed. Summary sensitivities and specificities were 0.91 (95% confidence interval [CI], 0.88-0.94) and 0.82 (95% CI, 0.75-0.87) by SSI and 0.89 (95% CI, 0.81-0.94) and 0.91 (95% CI, 0.84-0.95) by ARFI, respectively. The HSROCs for SSI and ARFI were 0.92 (95% CI, 0.90-0.94) and 0.96 (95% CI, 0.93-0.97), respectively. SSI and ARFI were both very informative, with probabilities of 83% and 91%, respectively, for correctly differentiating between benign and malignant breast masses following a "positive" measurement (over the threshold value) and probabilities of disease as low as 10% and 11%, respectively, following a "negative" measurement (below the threshold value) when the pre-test probability was 50%. SWE could be used as a good identification tool for the classification of breast masses.

    To evaluate the morphologic differential diagnosis of benign and malignant ductal breast tumors, as seen on US US findings in 29 pathologically proven cases of ductal breast tumor were retrospectively reviewed. All patients were female and their mean age was 42 years. Nineteen tumors were benign and ten were malignant, and all ductal or cystic lesions showed solid masses. According to the location of the mural nodule, we classified the sonographic appearance of these tumors into three types:intraductal, intracystic and amorphic. The intraductal type was divided into three subtypes:incompletely obstructive, completely obstructive and multiple mural nodules. For the intracystic type, too, three subtypes were designated:the intracystic mural nodule (mural cyst), intracystic mural nodule with the duct (mural cyst+duct) and intracystic multiple mural nodules. The amorphic type is defined as an atypical ductal tumor with the mural nodule extending into adjacent parenchyma. The margin of the duct or cyst was smooth in 68.4% of benign, and irregular in 90% of malignant ductal tumors. Internal echogeneity of the duct or cyst usually showed homogeneity in both benign and malignant tumors. 73.7% of tumors connecting the duct were benign and 50% were malignant. In benign tumors, 52.6% of mural nodule had an irregular margin, while in malignant tumors, the corresponding proportion was 100%;both types usually showed heterogeneous hypoechogeneity. Among benign tumors, the most common morphologic type was the intraductal incompletely obstructive subtype (36.8%);among those that were malignant, the amorphic type was most common, accounting for 40% of tumors. No amorphic type was benign and no incompletely obstructive subtype was malignant. When ductal breast tumors are morphologically classified on the basis of sonographic findings, the intraductal incompletely obstructive subtype suggests benignancy, and the amorphic type, malignancy. The morphologic classification of ductal

    A rapidly growing mass in the breast may be stressful for both parents and child as the suspicion of malignancy arises. The purpose of this case report is to draw attention to the fact that most emerging lesions of the breast in girls during puberty are benign. This case report presents a ten-year-old girl with a rapidly growing tumour in the breast. The tumour turned out to be a giant juvenile fibroadenoma, which is rare and benign. Differential diagnosis, investigation and management are reviewed.

    The total reflection X-ray fluorescence method was applied to study the trace element concentrations in human breast malignant and breast benign neoplasm tissues taken from the women who were patients of Holycross Cancer Centre in Kielce (Poland). These investigations were mainly focused on the development of new possibilities of cancer diagnosis and therapy monitoring. This systematic comparative study was based on relatively large (∼ 100) population studied, namely 26 samples of breast malignant and 68 samples of breast benign neoplasm tissues. The concentrations, being in the range from a few ppb to 0.1%, were determined for thirteen elements (from P to Pb). The results were carefully analysed to investigate the concentration distribution of trace elements in the studied samples. The measurements of concentration of trace elements by total reflection X-ray fluorescence were limited, however, by the detection limit of the method. It was observed that for more than 50% of elements determined, the concentrations were not measured in all samples. These incomplete measurements were treated within the statistical concept called left-random censoring and for the estimation of the mean value and median of censored concentration distributions, the Kaplan-Meier estimator was used. For comparison of concentrations in two populations, the log-rank test was applied, which allows to compare the censored total reflection X-ray fluorescence data. Found statistically significant differences are discussed in more details. It is noted that described data analysis procedures should be the standard tool to analyze the censored concentrations of trace elements analysed by X-ray fluorescence methods

    Full Text Available Foram estudadas 257 mulheres com diagnóstico de doença benigna de mama (DBM, atestado por anatomopatológico ou citologia, e um controle para cada uma delas. Foram apresentados resultados das possíveis relações entre variáveis reprodutivas e o risco para DBM. Os casos e controles foram comparados levando em conta a idade na menarca e na menopausa, o número de gravidezes, de meses em que amamentaram e de ciclos menstruais ovulatórios, e os antecedentes familiares de câncer de mama. Mostraram influência significativa, em relação às DBM, a nuliparidade, aumentando o risco enquanto a idade de 30 ou mais anos no primeiro parto o reduziu; o número de ciclos ovulatórios, que foi significativamente maior para os casos, e a média de meses de uso de pílula, menor entre as mulheres com DBM. O uso de contraceptivos orais apresentou um efeito protetor apenas quando a duração total do uso foi maior que dois anos. Os resultados não se revelaram novos ou diferentes se comparados com outros estudos, mas confirmam a relativa concordância entre os fatores de risco para DBM e para câncer de mama, ainda que as relações entre esses fatores e as DBM não sejam tão claras como o são para o câncer, e existam também algumas discrepâncias.The purpose of the study was the identification of risk factors for benign breast diseases (BBD; 257 women with BBD diagnosed through pathological anatomy or citology and a matched control for each were studied. Subjects were selected at The State University of Campinas Hospital and at a private clinic. To enter the study cases had to have a first diagnosis of BBD between October 1979 and August 1984. The following BBD were considered: dysplasia, fibroadenoma, cystic disease, papilloma and ductal ectasia. Reproductive variables were studied as risk factors, including menstrual ovulatory cycles. The date on which the BBD was diagnosed was defined as the index date. For controls, data were considered up to when

    All the spectrum is encompassed of those miscellaneous pathologic entities occurring in the mammary stroma which are on record up to date other than "mixed fibroepithelial" tumors (fibroadenomas and phyllodes tumors) and tumors both "pure" and "mixed" originating from myoepithelium (adenomyoepitheliomas and pleomorphic adenomas). Also they were excluded those dysreactive-autoimmune diseases (sarcoidosis, sclerosing lymphocytic lobulitis, lobular granulomatous mastitis) and those inflammatory-infectious conditions (tuberculosis, actinomycosis, foreign body reactions, Mondor's disease) which can mimick breast tumors clinically or on image analysis, but on the contrary not evoking the idea of a tumor on histology. Specifically, inflammatory pseudotumor, myofibroblastoma, leiomyoma, neurinoma/neurofibroma, benign fibrous histiocytoma, hemangiopericytoma, fibromatosis, nodular fascitis, variants of lipoma, mesenchymoma, amartoma and its variants, hemangiomas, pseudoangiomatous hyperplasia of stroma, amyloid tumor, granular cell tumor, are consecutively described and discussed, with a large list of references enclosed to each rubric. Most of the pictures are taken from personally observed lesions of the breast. Only few pictures referred to are from their analogue lesions which occurred in soft parts of other locations, with specific mention of that when it was the case. Of note after reviewing the literature the fact that no glomus tumor, nor Kaposi's sarcoma either sporadic or in the context of any immunodeficiency, nor myelolipoma has been recorded yet.

    Full Text Available Background: Benign breast tumors are common worldwide and various reports suggest an increasing incidence in Nigeria which necessitates an urgent need to differentiate it from malignant tumors. The study was carried out to classify and determine the pattern, frequency, age, and sex distribution of benign breast tumors seen in a tertiary hospital. Materials and Methods: This was a 10-year retrospective study of all benign breast tumors diagnosed at the Pathology Department of a teaching hospital from January 1 2001 to December 31 2010. Results: A total of 1566 breast tumors were diagnosed during the study period, 1035 cases of benign breast tumors constituting 66.3% of all breast tumors were seen. The female to male ratio was 72.9:1. The overall mean age for benign breast tumor was 29 years with a peak age occurrence in the third decade. Fibroadenoma (FA was the most common benign breast tumor followed by fibrocystic change and they accounted for 47.1% and 25.4% of benign breast tumors with mean age of 24.7 years and 33.4 years, respectively. FA has a peak occurrence in the third decade while fibrocystic change has a peak occurrence in the fourth decade. Other major tumors encountered were tubular adenoma (6.0%, lactating adenoma (5.6%, benign phyllodes (4.8%, sclerosing adenoma (3.3%, and blunt duct adenoma (2.5%. Gynecomastia (1.4% was the only benign breast tumor seen in males.Conclusions: Benign breast tumors are quite common, presenting mostly as FA and fibrocystic change. The tumors are seen in both sexes with a striking female preponderance and occurred predominantly in young females with a peak in the third decade. The findings are generally similar to the most previous studies from Nigeria, Africa, and the Western world with minimal variations.

    Fibrocystic mastopathy (FM), a benign lesion, is considered by many author like a premalignant lesion. Breast carcinoma (CA) represents the most frequent female tumor and the second mortality cause through cancer, after the bronchopulmonary cancer. At the Department of Pathology from Tg. Mureş, we selected 190 cases, for 10 month: 102 presented FM, 41 CA and 47 CA + FM. In every case, we have examined 2 slides stained with HE. In difficult cases, we performed special stains (van Gieson, H-PAS, Alcian). We studied the pulmonary tumor, adjacent mammary tissue and axillary lymph nodes. The present data of literature and the experience of the Department of Pathology from Tg. Mureş showed a strong relationship between the presence of FM and the appearance of CA: both lesions have a common field of hormonal disfunction and intraductal and intralobular hyperplasia (an microscopic feature of mastopathy) increase the risk of CA.

    Radiation therapy of benign diseases represent a wide panel of indications. Some indications are clearly identified as treatment of arteriovenous malformations (AVM), hyperthyroid ophthalmopathy, postoperative heterotopic bone formations or keloid scars. Some indications are under evaluation as complications induced by neo-vessels of age-related macular degeneration or coronary restenosis after angioplasty. Some indications remain controversial with poor evidence of efficiency as treatment of bursitis, tendinitis or Dupuytren`s disease. Some indications are now obsolete such as warts, or contra-indicated as treatment of infant and children. (authors)

    The aim of this study was to investigate the diagnostic value of the Virtual Touch™ tissue quantification (VTQ) and elastosonography technologies in benign and malignant breast tumors. Routine preoperative ultrasound, elastosonography and VTQ examinations were performed on 86 patients with breast lesions. The elastosonography score and VTQ speed grouping of each lesion were measured and compared with the pathological findings. The difference in the elastosonography score between the benign and malignant breast tumors was statistically significant (Pbenign and malignant tumors was also statistically significant (P<0.05). In addition, the diagnostic accuracy of conventional ultrasound, elastosonography, VTQ technology and the combined methods showed statistically significant differences (P<0.05). The use of the three technologies in combination significantly improved the diagnostic accuracy to 91.86%. In conclusion, the combination of conventional ultrasound, elastosonography and VTQ technology can significantly improve accuracy in the diagnosis of breast cancer. PMID:25187797

    Highlights: • New view-sharing sequences (e.g. TWIST) enable ultrafast dynamic breast MRI. • TWIST sequences accurately characterize the inflow of contrast in breast lesions. • TTE evaluation allows breast lesion classification with very high accuracy. • The use of TTE significantly increases the specificity of breast MRI. • TWIST imaging may increase the potential of breast MRI as screening tool. - Abstract: Objectives: To investigate time to enhancement (TTE) as novel dynamic parameter for lesion classification in breast magnetic resonance imaging (MRI). Methods: In this retrospective study, 157 women with 195 enhancing abnormalities (99 malignant and 96 benign) were included. All patients underwent a bi-temporal MRI protocol that included ultrafast time-resolved angiography with stochastic trajectory (TWIST) acquisitions (1.0 × 0.9 × 2.5 mm, temporal resolution 4.32 s), during the inflow of contrast agent. TTE derived from TWIST series and relative enhancement versus time curve type derived from volumetric interpolated breath-hold examination (VIBE) series were assessed and combined with basic morphological information to differentiate benign from malignant lesions. Receiver operating characteristic analysis and kappa statistics were applied. Results: TTE had a significantly better discriminative ability than curve type (p < 0.001 and p = 0.026 for reader 1 and 2, respectively). Including morphology, sensitivity of TWIST and VIBE assessment was equivalent (p = 0.549 and p = 0.344, respectively). Specificity and diagnostic accuracy were significantly higher for TWIST than for VIBE assessment (p < 0.001). Inter-reader agreement in differentiating malignant from benign lesions was almost perfect for TWIST evaluation (κ = 0.86) and substantial for conventional assessment (κ = 0.75). Conclusions: TTE derived from ultrafast TWIST acquisitions is a valuable parameter that allows robust differentiation between malignant and benign breast lesions with high

    Objective: To determine whether dynamic contrast enhanced MRI features of early-phase enhancement rate, enhancement amplitude, and signal intensity (SI) time course are associated with the microvessel density (MVD) and vascular endothelial growth factor (VEGF) expression of malignant and benign breast lesions. Methods: Thirty-eight patients with histopathologically verified breast lesions underwent dynamic contrast enhanced MRI. SI changes during dynamic scanning were assessed quantitatively. Early-phase enhancement rate and enhancement amplitude were calculated. Time-SI curves of the lesions were obtained and classified according to their shapes as type I (which was steady enhancement to the end of the dynamic data acquisition at 7.5 min), type II (plateau of SI after avid initial contrast enhancement), or type III (washout of SI after avid initial contrast enhancement). the mean MVD and VEGF expression of the lesions were measured with immuno-histochemical staining method in all the histologic specimens by pathologists without the knowledge of the results of the MR examination. The relationships among dynamic contrast enhanced MRI features, MVD, and VEGF expression of benign and malignant breast lesions were analyzed. Results: Histology revealed 21 malignancies and 17 benign lesions. The mean MVD and VEGF expression for 21 malignant lesions were statistically higher than the mean MVD and VEGF expression for 17 benign lesions. High VEGF expression of benign and malignant breast lesions showed an association with increased MVD. Among all 38 lesions, greater (> 60%) MR early-phase enhancement rate and time-SI curve type II and III showed an association with increased MVD and higher VEGF expression level. All the differences mentioned above showed statistical significance except that the difference between VEGF expression and the distribution of curve types had no statistical significance. No significant relationships were observed between the mean of enhancement

Methods: X-ray image changes of 63 malignant breast neoplasms were described by the mammography and in comparision with those of 43 benign masses. Results: The accordance percentages between the X-ray and histological examinations for the benign and malignant neoplasms were shown as 85% and 90.6% respectively. Spiculated mass, calcification granules in clusters and other images were found to be indication of benign or malignant breast lesion. Conclusion: The High Frequency Molybdenum-target X-ray Photography can provide effective imaging data for diagnosis and distinguish between the benign and malignant breast lesions. (authors)

    To evaluate the effectiveness and the most accurate element of the diagnostic criteria of the Japan Society of Ultrasonics in medicine (JSUM, Nov. 1989) for distinguishing between benign and malignant solid breast masses on the US. We analyzed the ultrasonic findings of histopathologically proved 51 fibroadenomas, 12 fibrocystic disease, and 39 breast cancers in relation to the diagnostic criteria of the JSUM (shape, border, boundary echo, internal echo, posterior echo, lateral echo, and depth/width ratio). The number of cases of fibroadenoma, fibrocystic disease, and breast cancer corresponding to the diagnostic criteria was in the shape (26/51, 5/12, 33/39), border (41/51, 9/12, 29/39), boundary echo (48/51, 12/12, 27/39) internal echo (43/51, 9/12, 24/39), posterior echo (32/51, 3/12, 21/39), and lateral shadowing (15/51, 1/12, 35/39). All diagnostic criterias showed statistical significance for differentiation of benign/malignant breast mass on the US (Chi-square test: ρ < 0.05). The order of accuracy was boundary echo, internal echo, and border. The mean of depth/width ratio was 0.54 ± 0.15, 0.52 ± 0.12, and 0.69 ± 0.21 in fibroadenoma, fibrocystic disease, and breast cancer respectively and it had statistical significance for differentiation of benign/malignant breast mass on the US (ANOVA test: ρ = 0.0002). The diagnostic criteria of JSUM is effective for differentiation of benign/malignant breast solid masses on the US and has accuracy in the order of boundary echo, internal echo, and border. Depth/width ratio also has statistical significance

We analyzed the ultrasonic findings of histopathologically proved 51 fibroadenomas, 12 fibrocystic disease, and 39 breast cancers in relation to the diagnostic criteria of the JSUM (shape, border, boundary echo, internal echo, posterior echo, lateral echo, and depth/width ratio). The number of cases of fibroadenoma, fibrocystic disease, and breast cancer corresponding to the diagnostic criteria was in the shape (26/51, 5/12, 33/39), border (41/51, 9/12, 29/39), boundary echo (48/51, 12/12, 27/39) internal echo (43/51, 9/12, 24/39), posterior echo (32/51, 3/12, 21/39), and lateral shadowing (15/51, 1/12, 35/39). All diagnostic criterias showed statistical significance for differentiation of benign/malignant breast mass on the US (Chi-square test: {rho} < 0.05). The order of accuracy was boundary echo, internal echo, and border. The mean of depth/width ratio was 0.54 {+-} 0.15, 0.52 {+-} 0.12, and 0.69 {+-} 0.21 in fibroadenoma, fibrocystic disease, and breast cancer respectively and it had statistical significance for differentiation of benign/malignant breast mass on the US (ANOVA test: {rho} = 0.0002). The diagnostic criteria of JSUM is effective for differentiation of benign/malignant breast solid masses on the US and has accuracy in the order of boundary echo, internal echo, and border. Depth/width ratio also has statistical significance.

    Version 4 of the guideline for radioiodine therapy for benign thyroid diseases includes an interdisciplinary consensus ondecision making for antithyroid drugs, surgical treatment and radioiodine therapy. The quantitative description of a specific goiter volume for radioiodine therapy or operation was cancelled. For patients with nodular goiter with or without autonomy, manifold circumstances are in favor of surgery (suspicion on malignancy, large cystic nodules, mediastinal goiter, severe compression of the trachea) or in favor of radioiodine therapy (treatment of autonomy, age of patient, co-morbidity, history of prior subtotal thyroidectomy, profession like teacher, speaker or singer). For patients with Graves' disease, radioiodine therapy or surgery are recommended in the constellation of high risk of relapse (first-line therapy), persistence of hyperthyroidism or relapse of hyperthyroidism. After counseling, the patient gives informed consent to the preferred therapy. The period after radioiodine therapy of benign disorders until conception of at least four months was adapted to the European recommendation. (orig.)

    To determine whether the compression technique is a valuable additional method for differentiating between benign and malignant breast masses. The ultrasonographic findings of 95 benign and 53 malignant masses, all pathologically proven, were prospectively analyzed with regard to five diagnostic criteria: shape (regular/irregular), retrotumoral acoustic phenomena (posterior enhancement/posterior attenuation), internal echo pattern (homogeneous/inhomogeneous), compression effect on shape (distortion/no change), and compression effect on internal echo pattern (more homogeneous/no change). The number of cases of benign and malignant masses, respectively, was as follows: regular/irregular shape: 84/11, 9/44; posterior acoustic enhancement/posterior attenuation: 82/13, 16/37; homogeneous/inhomogeneous internal echo pattern: 78/17, 14/39; distortion/no change in shape: 76/19, 5/48; and more homogeneous/no change in internal echo pattern: 71/24, 3/50. For all diagnostic criteria for the differentiation of benign and malignant masses, the differences were statistically significant (p<.05). Ultrasonography is helpful for differentiating between benign and malignant breast masses. The compression technique is a valuable additional diagnostic method

    The purpose of this study was to investigate the diagnostic performance of mammographic texture analysis in the differential diagnosis of benign and malignant breast tumors. Digital mammography images were obtained from the Picture Archiving and Communication System at our institute. Texture features of mammographic images were calculated. Mann-Whitney U test was used to identify differences between the benign and malignant group. The receiver operating characteristic (ROC) curve analysis was used to assess the diagnostic performance of texture features. Significant differences of texture features of histogram, gray-level co-occurrence matrix (GLCM) and run length matrix (RLM) were found between the benign and malignant breast group (P  .05). The AUROCs of imaging-based diagnosis, texture analysis, and imaging-based diagnosis combined with texture analysis were 0.873, 0.863, and 0.961, respectively. When imaging-based diagnosis was combined with texture analysis, the AUROC was higher than that of imaging-based diagnosis or texture analysis (P benign and malignant breast tumors. Furthermore, the combination of imaging-based diagnosis and texture analysis can significantly improve diagnostic performance. Copyright © 2017 Elsevier Inc. All rights reserved.

    To investigate the general applicability of ultrasonography (US) and clinical findings in differentiating benign from malignant solid nodules in the subareolar area of the breast. From March 2001 to March 2003, pathologically proven 84 nodules from 78 patients were included in this study. Two radiologists evaluated the shape, margins, internal echotexture, internal echogenicity, posterior echo intensity and relation with the major ducts, and each nodule was then classified as benign or malignant. Clinical findings were divided into either or absence of symptom. The ultrasonographic, mammographic and clinical classifications were compared with the pathological results. The sensitivity (SE), specificity (SP), positive predictive values (PPV) and negative predictive values (NPV) were calculated for ultrasonographic, mammographic and clinical classifications. Sixteen nodules were proved to be malignant (7 ductal carcinoma in situ and 9 invasive ductal carcinoma), and the remaining 68 nodules were benign. SE, SP, PPV, and NPV of breast cancer according to the ultrasonographical classification were 100%, 61.8%, 38.1% and 100% while those of the clinical classification were 81.3%, 73.5%, 41.9% and 94.3%, respectively. Relation with the major ducts such as ductal communication or intraductal location demonstrated a high SE (87.5%) and NPV (92.0%). Ultrasonographic and clinical findings can be helpful in the differentiation of benign solid nodules from malignant lesions in the subareolar area of the breast.

    Breast cancer is a heterogeneous disease associated with different patient prognosis and responses to therapy. Vitamin D has been emerging as a potential treatment for cancer, as it has been demonstrated that it modulates proliferation, apoptosis, invasion and metastasis, among others. It acts mostly through the Vitamin D receptor (VDR) and the synthesis and degradation of this hormone are regulated by the enzymes CYP27B1 and CYP24A1, respectively. We aimed to study the expression of these three proteins by immunohistochemistry in a series of breast lesions. We have used a cohort comprising normal breast, benign mammary lesions, carcinomas in situ and invasive carcinomas and assessed the expression of the VDR, CYP27B1 and CYP24A1 by immunohistochemistry. The results that we have obtained show that all proteins are expressed in the various breast tissues, although at different amounts. The VDR was frequently expressed in benign lesions (93.5%) and its levels of expression were diminished in invasive tumours (56.2%). Additionally, the VDR was strongly associated with the oestrogen receptor positivity in breast carcinomas. CYP27B1 expression is slightly lower in invasive carcinomas (44.6%) than in benign lesions (55.8%). In contrast, CYP24A1 expression was augmented in carcinomas (56.0% in in situ and 53.7% in invasive carcinomas) when compared with that in benign lesions (19.0%). From this study, we conclude that there is a deregulation of the Vitamin D signalling and metabolic pathways in breast cancer, favouring tumour progression. Thus, during mammary malignant transformation, tumour cells lose their ability to synthesize the active form of Vitamin D and respond to VDR-mediated Vitamin D effects, while increasing their ability to degrade this hormone

    Purpose: The authors assessed the characteristics of benign and malignant solid breast tumors in harmonic three-dimensional (3D) power Doppler imaging and proposed decision models to classify benign and malignant breast tumors. Materials and methods: A total of 86 malignant and 97 benign harmonic 3D power Doppler US images were analyzed. All the harmonic 3D power Doppler images were obtained using a Voluson730 US system (GE, Zipf, Austria) equipped with a RSP 6-12 transducer and tissue harmonic imaging modalities. Imaging analysis was performed using the Virtual Organ Computer-aided Analysis (VOCAL)-imaging program. Histogram indices, the vascularization index (VI), flow index (FI) and vascularization-flow index (VFI), were calculated for the intra-tumor and for shells with an outside thickness of 3 mm surrounding the breast tumors. The receiver operating characteristic (ROC) curves were calculated to estimate the diagnostic performances. Results: The results revealed that the choice of decision model comprised the parameters of patient age, intra-tumor VI, and tumor volume to classify benign and malignant breast tumors. The area under the ROC curve (Az) was 0.910, accuracy was 81.4%, and sensitivity and specificity were 81.4% and 81.4%, respectively. The parameter intra-tumor VI was the choice for all of the histogram indices in differentiating between malignant and benign lesions. Conclusion: The decision model, which was composed of patient age, tumor volume and intra-tumor VI, and a cut-off value for intra-tumor VI at the upper end of patient age and tumor volume, was recommended in clinical application.

    We aimed to determine the correlations between the elasticity values of solid breast masses and histopathological findings to define cutoff elasticity values differentiating malignant from benign lesions. A total of 115 solid breast lesions of 109 consecutive patients were evaluated prospectively using shear wave elastography (SWE). Two orthogonal elastographic images of each lesion were obtained. Minimum, mean, and maximum elasticity values were calculated in regions of interest placed over the stiffest areas on the two images; we also calculated mass/fat elasticity ratios. Correlation of elastographic measurements with histopathological results were studied. Eighty-three benign and thirty-two malignant lesions were histopathologically diagnosed. The minimum, mean, and maximum elasticity values, and the mass/fat elasticity ratios of malignant lesions, were significantly higher than those of benign lesions. The cutoff value was 45.7 kPa for mean elasticity (sensitivity, 96%; specificity, 95%), 54.3 kPa for maximum elasticity (sensitivity, 95%; specificity, 94%), 37.1 kPa for minimum elasticity (sensitivity, 96%; specificity, 95%), and 4.6 for the mass/fat elasticity ratio (sensitivity, 97%; specificity, 95%). SWE yields additional valuable quantitative data to ultrasonographic examination on solid breast lesions. SWE may serve as a complementary tool for diagnosis of breast lesions. Long-term clinical studies are required to accurately select lesions requiring biopsy.

    The development of microwave breast cancer detection and treatment techniques has been driven by reports of substantial contrast in the dielectric properties of malignant and normal breast tissues. However, definitive knowledge of the dielectric properties of normal and diseased breast tissues at microwave frequencies has been limited by gaps and discrepancies across previously published studies. To address these issues, we conducted a large-scale study to experimentally determine the ultrawideband microwave dielectric properties of a variety of normal, malignant and benign breast tissues, measured from 0.5 to 20 GHz using a precision open-ended coaxial probe. Previously, we reported the dielectric properties of normal breast tissue samples obtained from reduction surgeries. Here, we report the dielectric properties of normal (adipose, glandular and fibroconnective), malignant (invasive and non-invasive ductal and lobular carcinomas) and benign (fibroadenomas and cysts) breast tissue samples obtained from cancer surgeries. We fit a one-pole Cole-Cole model to the complex permittivity data set of each characterized sample. Our analyses show that the contrast in the microwave-frequency dielectric properties between malignant and normal adipose-dominated tissues in the breast is considerable, as large as 10:1, while the contrast in the microwave-frequency dielectric properties between malignant and normal glandular/fibroconnective tissues in the breast is no more than about 10%.

    Full Text Available Purpose: The purpose of this study was to describe the breast ultrasonography (US features and to investigate whether performing a core biopsy is warranted in young women having palpable solid breast masses. Methods: A total of 76 solid palpable masses in 68 consecutive women (≤25 years old underwent tissue diagnosis by percutaneous core biopsy. Two radiologists, who were blinded to the clinical history and histopathology, independently evaluated the US features according to Breast Imaging-Reporting and Data System (BI-RADS lexicon. The frequency of benign and malignant descriptor terms that were used to characterize the lesions were compared to the final pathology. Results: All 76 palpable solid masses yielded benign pathology. On the US, the shape of the mass was described by radiologists 1 and 2 as oval or round (63.2% and 71.1%, margin as circumscribed (68.4% and 77.6% and orientation as parallel (85.5% and 90.8%; the frequency of using all three benign descriptors was 61.8% and 68.5%, respectively. Suspicious descriptors were used less frequently by radiologists 1 and 2 including irregular shape (9.2% and 13.1%, non-circumscribed margin (31.6% and 22.4% and non-parallel orientation (14.5% and 9.2%; the frequency of using all three suspicious descriptors was 9.2% and 11.8%, respectively. Conclusion: Despite the variable US features, breast malignancy seems extremely low in 25 years or younger women for palpable breast lesions. Using the BI-RADS lexicon, US accurately predicted benignity in about two thirds of our patients, supporting US surveillance as a safe alternative to invasive tissue sampling in this setting.

    To determine MTRs for normal structures and benign diseases in the breast two-dimensional magnetization transfer imaging was performed in 62 patients and in 3 young female volunteers. With regard to the MTRs of measurements in the normal breast tissues, fat tissues which is close to simple cysts in MTRs show little transfer of longitudinal magnetization. MTRs of the muscles was 15.15{+-}6.22%, which exceeded those of breast parenchyma. The breast parenchyma didn`t show the change of MTR value due to the difference of patient age and due to variable amount of fat and fibrous tissues. Breast parenchyma in the two young volunteers clearly showed biphasic change of MTR values in accordance with the menstrual cycle; little transfer value was due to hydration in the postovulatory period and high transfer value was due to dehydration in the preovulatory period. In the remaining one volunteer during lactation period, mammary parenchyma shows sever decrease in MTR, because mammary gland is loaded with massive fluid, showing a very high signal intensity on First IR and T2-weighted images. MTR values of benign breast diseases including mastopathy, fibroadenoma and phyllodes tumor had no significant difference from those of the breast parenchyma and muscle. Non-invasive ductal carcinoma was equivalent to breast parenchyma in MTR. (K.H.)

    Both neurologists and urologists might encounter patients with acute urinary retention due to benign inflammatory nervous diseases. Based on the mechanism of urinary retention, these disorders can be divided into two subgroups: disorders of the peripheral nervous system (e.g., sacral herpes) or the central nervous system (e.g., meningitis-retention syndrome [MRS]). Laboratory abnormalities include increased herpes virus titers in sacral herpes, and increased myelin basic protein in the cerebrospinal fluid (CSF) in some cases with MRS. Urodynamic abnormality in both conditions is detrusor areflexia; the putative mechanism of it is direct involvement of the pelvic nerves in sacral herpes; and acute spinal shock in MRS. There are few cases with CSF abnormality alone. Although these cases have a benign course, management of the acute urinary retention is necessary to avoid bladder injury due to overdistension. Clinical features of sacral herpes or MRS differ markedly from those of the original "Elsberg syndrome" cases.

    In a prospective study using mammographically guided fine needle aspirates in 100 nonpalpable breast lesions, the author's group assessed the reliability of a cytological grading system to define the cytological features of proliferative and nonproliferative breast disease and to differentiate between benign, premalignant and malignant breast lesions. We developed a cytological grading system evaluating the aspirates for the cellular arrangement, the degrees of cellular pleomorphism and anisonucleosis, presence of myoepithelial cells and nucleoli and the status of the chromatin pattern. This grading system, now recognized as the Masood Cytology Index, is commonly used as a surrogate end point biomarker in chemoprevention trials.

    Shear wave elastography (SWE) is a promising adjunct to greyscale ultrasound in differentiating benign from malignant breast masses. The purpose of this study was to characterise breast cancers which are not stiff on quantitative SWE, to elucidate potential sources of error in clinical application of SWE to evaluation of breast masses. Three hundred and two consecutive patients examined by SWE who underwent immediate surgery for breast cancer were included. Characteristics of 280 lesions with suspicious SWE values (mean stiffness >50 kPa) were compared with 22 lesions with benign SWE values (masses were more often soft on SWE than masses representing invasive breast cancer. Invasive cancers that were soft were more frequently: histological grade 1, tubular subtype, ≤10 mm invasive size and detected at screening mammography. No significant differences were found with respect to the presence of invasive lobular cancer, vascular invasion, hormone and HER-2 receptor status. Lymph node positivity was less common in soft cancers. Malignant breast masses classified as benign by quantitative SWE tend to have better prognostic features than those correctly classified as malignant. • Over 90 % of cancers assessable with ultrasound have a mean stiffness >50 kPa. • 'Soft' invasive cancers are frequently small (≤10 mm), low grade and screen-detected. • Pure DCIS masses are more often soft than invasive cancers (>40 %). • Large symptomatic masses are better evaluated with SWE than small clinically occult lesions. • When assessing small lesions, 'softness' should not raise the threshold for biopsy.

    Myofibroblastoma is an unusual benign tumour of the breast predominantly seen in men in their sixth to seventh decade. The gross appearance is that of a well circumscribed nodule, characteristically small, seldom exceeding 3 cm. We present a case of an unusually large myofibroblastoma, which mimicked a malignant breast tumour. A 40 years old male, known case of tetralogy of Fallot, was operated in infancy in abroad, presented with a rapid enlargement of right breast over 5 - 6 weeks. Examination revealed a firm 10 cm hemispherical lump occupying the whole of the right breast with normal overlying skin. Since core biopsy was inconclusive, a subcutaneous mastectomy was performed to remove the tumour, which weighed 500 gms. Histopathology and immunocytochemistry revealed a mixed classical and collagenised type of myofibroblastoma. The patient is well with no evidence of recurrence. (author)

  18. A diagnostic dilemma in breast pathology – benign fibroadenoma with multinucleated stromal giant cells

    Full Text Available Abstract Fibroadenomas are common benign breast tumours that display a characteristic pathological morphology, although several epithelial and stromal variations exist. A very rare histological finding is the presence of multinucleated giant cells throughout the stroma of a benign fibroadenoma. Cells of this type, which are more commonly found incidentally within the interlobular stroma of breast tissue, are benign and should not be mistaken for malignant cells on microscopic examination. Unfortunately a lack of awareness of this pathological entity can lead to diagnostic confusion amongst pathologists resulting in the multinucleate giant cells being mistaken for highly mitotic cells and consequently the fibroadenoma being mistaken for a malignant lesion. This may have serious implications for the subsequent management of the patient. The presence of this unusual cell type in the stroma does not alter the prognosis of otherwise benign lesion. We encountered two such cases at our institution in a six month period recently. We present their histories along with relevant radiological, microscopic and immunohistochemical features, followed by a discussion of this unusual pathological entity.

    The spontaneous infarction of benign breast lesions is a rare entity and hence is not usually considered in the differential diagnosis during radiologic or clinical examination. There have been a few published cases of infarction during pregnancy and lactation. In this study we report the ultrasonographic and pathologic features of a spontaneous infarction of a lactating adenoma with acute mastitis and abscess and a spontaneously infarcted fibroadenoma.

    The role of radiation therapy in the treatment of malignant disease has long been accepted. More limited application of radiation in the treatment of benign conditions has been proven but generally not pursued. On the centennial anniversary of radiation therapy, a promising, but as yet unproved, application of radiation for treatment of benign vascular disease has become an exciting field of research, speculation, and controversy. This panel presentation will discuss the rationales and dilemmas of applying radiation in the prevention of arterial restenosis after therapeutic intervention. Coronary artery bypass grafting and more recently coronary angioplasty have become accepted, effective therapies to reverse significant coronary stenosis, and thereby benefit the majority of patients with coronary artery disease. However, a large proportion of patients will suffer restenosis in spite of optimal conventional therapy. The search for a means to prevent such restenosis has been partially successful by therapies, and even engineering intravascular devices. In spite of these efforts, a significant number of patients will fail today's conventional therapy and suffer arterial restenosis. Fibroblast myointimal proliferation is felt to be a major element in this restenosis process. Clinical experience shows that radiation inhibits other similar benign fibroblast proliferative processes such as keloid scar formation and heterotopic ossification. Radiation is now being considered as a means to inhibit myointimal fibroblast proliferation and hopefully prevent attendant arterial restenosis as well. This has catalyzed various animal model investigations that have shown significant arteries. Promising results in the animal model and in very early human institutional trials. These trials are designed to determine if radiation is truly effective and can be safely delivered to prevent restenosis in diseased human arteries. This panel discussion will provide a firm basic science and

    Background : Breast cancer is the most common invasive cancer in females worldwide. It accounts for 16% of all female cancers and 22.9% of invasive cancers in women. 18.2% of all cancer deaths worldwide including both males and females are from breast cancer. In this study we compared few serum elements in patients with benign and malignant breast tumor to find any related prognostic and predictive value. A case-control study was carried out in a hospital (Tehran - Iran) in 2012. Target population was divided in 2 groups; subjects with benign and malignant breast tumors. We did preoperative hematological test. Five milliliter fasting blood vein was collected, centrifuged in 3000 g for 15 minutes to obtain serum. We measured serum Calcium (Ca), Phosphorus (P), Magnesium (Mg), Zinc (Zn), and high sensitive-CRP, analyzed statistically and compared recorded elements in 2 groups by software package SPSS version 16. The level of significant was considered P benign and malignant breast disease.

    To determine the diagnostic performance of volumetric quantitative dynamic contrast-enhanced MRI (qDCE-MRI) in differentiation between malignant and benign breast lesions. DCE-MRI was performed in 124 patients with 136 breast lesions. Quantitative pharmacokinetic parameters K trans , K ep , V e , V p and semi-quantitative parameters TTP, MaxCon, MaxSlope, AUC were obtained by using a two-compartment extended Tofts model and three-dimensional volume of interest. Morphologic features (lesion size, margin, internal enhancement pattern) and time-signal intensity curve (TIC) type were also assessed. Logistic regression analysis was used to determine predictors of malignancy, followed by receiver operating characteristics (ROC) analysis to evaluate the diagnostic performance. qDCE parameters (K trans , K ep , V p , TTP, MaxCon, MaxSlope and AUC), morphological parameters and TIC type were significantly different between malignant and benign lesions (P≤0.001). Multivariate logistic regression analyses showed that K trans , K ep , MaxSlope, size, margin and TIC type were independent predictors of malignancy. The diagnostic accuracy of logistic models based on qDCE parameters alone, morphological features plus TIC type, and all parameters combined was 94.9%, 89.0%, and 95.6% respectively. qDCE-MRI can be used to improve diagnostic differentiation between benign and malignant breast lesions in relation to morphology and kinetic analysis.

    To assess the potential clinical utility of in-vivo 31P magnetic resonance spectroscopy (MRS) in patients with various malignant and benign breast lesions. Seventeen patients with untreated primary malignant breast lesions (group I), eight patients with untreated benign breast lesions (group II) and seven normal breasts (group III) were included in this study. In-vivo 31P MRS was performed using a 1.5 Tesla MR scanner. Because of the characteristics of the coil, the volume of the tumor had to exceed 12 cc (3x2x2 cm), with a superoinferior diameter at least 3 cm. Mean and standard deviations of each metabolite were calculated and metabolite ratios, such as PME/PCr, PDE/PCr, T-ATP/PCr and PCr/T-ATP were calculated and statistically analyzed. Significant differences in PME were noted between groups I and III (p=0.0213), and between groups II and III (p=0.0213). The metabolite ratios which showed significant differences were PME/PCr (between groups II and III) (p=0.0201), PDE/PCr (between groups I and III, and between groups II and III) (p=0.0172), T-ATP/PCr (between groups II and III) (p=0.0287), and PCr/T-ATP (between groups II and III) (p=0.0287). There were no significant parameters between groups I and II. In-vivo 31P MRS is not helpful for establishing a differential diagnosis between benign and malignant breast lesions, at least with relatively large lesions greater than 3 cm in one or more dimensions

    Diffusion-weighted magnetic resonance imaging (DW-MRI) is different from conventional diagnostic methods and has the potential to delineate the microscopic anatomy of a target tissue or organ. The purpose of our study was to evaluate the value of DW-MRI in the diagnosis of benign and malignant breast masses, which would help the clinical surgeon to decide the scope and pattern of operation. A total of 52 female patients with palpable solid breast masses received breast MRI scans using routine sequences, dynamic contrast-enhanced imaging, and diffusion-weighted echo-planar imaging at b values of 400, 600, and 800 s/mm(2), respectively. Two regions of interest (ROIs) were plotted, with a smaller ROI for the highest signal and a larger ROI for the overall lesion. Apparent diffusion coefficient (ADC) values were calculated at three different b values for all detectable lesions and from two different ROIs. The sensitivity, specificity, positive predictive value, and positive likelihood ratio of DW-MRI were determined for comparison with histological results. A total of 49 (49/52, 94.2%) lesions were detected using DW-MRI, including 20 benign lesions (two lesions detected in the same patient) and 29 malignant lesions. Benign lesion had a higher mean ADC value than their malignant counterparts, regardless of b value. According to the receiver operating characteristic (ROC) curve, the smaller-range ROI was more effective in differentiation between benign and malignant lesions. The area under the ROC curve was the largest at a b value of 800 s/mm(2). With a threshold ADC value at 1.23 × 10(-3) mm(2)/s, DW-MRI achieved a sensitivity of 82.8%, specificity of 90.0%, positive predictive value of 92.3%, and positive likelihood ratio of 8.3 for differentiating benign and malignant lesions. DW-MRI is an accurate diagnostic tool for differentiation between benign and malignant breast lesions, with an optimal b value of 800 s/mm(2). A smaller-range ROI focusing on the

    In summary, the lecture presents today's state of nuclear medical diganostics in benign bone disease, the radiopharmaceuticals, and the methods used. Besides the 99 m-Tc-labeled diphosphonates a couple of additional radioactive labeled substances play an important part in bone scintigraphic imaging especially in scanning inflammatory bone disease and the bone marrow. There are several substances available to label leucocytes and human immunoglobulins. Concerning the methods the performance of the 3-phase bone scanning and the application of SPECT becomes increasingly important. In detail discussed are among other methods the inflammation-scanning in osteomyelitis, the scintigraphic imaging in benign bone tumors and tumor like lesions, in circulation disorders of the bone with necroses and hyperperfusion (reflex sympathetic dystrophy, transient hip osteoporosis), and in bone lesions following trauma or stress, for example also in battered child syndrome. The indication to the different imaging procedures as X-ray, computed tomography, nuclear magnetic resonance, and scintigraphic imaging are discussed, whereby the scintiscanning urges its place, mainly due to good specifity, in documenting the different functional states of the bone such as inflammation, perfusion, necrosis, tumor and/or bone marrow infiltration.

    Idiopathic granulomatous lobular mastitis (IGLM) is a rare chronic inflammatory disease of the breast with obscure etiology that mimics invasive carcinoma both clinically and radiologically. The treatment of IGLM remains controversial. The aim of proper management is to use a combination of medical and surgical treatment of this benign condition to achieve a good cosmetic result and low recurrence rate. A retrospective analysis of 19 patients with IGLM is performed based on the findings of clinical, radiological, and pathological examinations. The results of two treatments are presented: medical treatment with oral corticosteroids, and consecutive surgical excision after a follow-up period of 20 months (range, 6-75 months). The majority of patients treated in this paper were young (mean, 34 years) parous women with a history of hormonal medication use. The main clinical finding is large, irregular, and painful mass. Hypoechoic lobulated, irregular tubular or oval shaped masses had been imaged by ultrasound. Mammographic findings were an ill-defined mass, enlarged axillary lymph nodes, asymmetric density, and architectural distortion. Diagnoses of IGLM had been established by cytological or histological examination. Symptoms subside and inflammatory changes regressed with medical treatment. The remaining lesions were excised by consecutive breast conserving surgery. The disease recurred in one patient during the follow-up period. IGLM is an inflammatory breast disease found in young women who present with a large painful irregular mass, which mimics carcinoma, as a physical change. Breast imaging modalities are not helpful to differentiate IGLM from invasive cancer. The correct diagnosis is established by cytological or histological examination. Medical treatment with corticosteroids provides significant regression of the inflammatory disease, allowing more conservative surgery. Consecutive surgical excision of the remaining lesions with good cosmetic results

    Previous studies have emphasized that genetic susceptibility to breast cancer is rare and is expressed primarily as premenopausal breast cancer, bilateral breast cancer, or both. Proliferative breast disease (PBD) is a significant risk factor for the development of breast cancer and appears to be a precursor lesion. PBD and breast cancer were studied in 103 women from 20 kindreds that were selected for the presence of two first degree relatives with breast cancer and in 31 control women. Physical examination, screening mammography, and four-quadrant fine-needle breast aspirates were performed. Cytologic analysis of breast aspirates revealed PBD in 35% of clinically normal female first degree relatives of breast cancer cases and in 13% of controls. Genetic analysis suggests that genetic susceptibility causes both PBD and breast cancer in these kindreds. This study supports the hypothesis that this susceptibility is responsible for a considerable portion of breast cancer, including unilateral and postmenopausal breast cancer

  13. Differential CARM1 Isoform Expression in Subcellular Compartments and among Malignant and Benign Breast Tumors.

    Full Text Available Coactivator-associated arginine methyltransferase 1 (CARM1 is a coactivator for ERα and cancer-relevant transcription factors, and can methylate diverse cellular targets including histones. CARM1 is expressed in one of two alternative splice isoforms, full-length CARM1 (CARM1FL and truncated CARM1 (CARM1ΔE15. CARM1FL and CARM1ΔE15 function differently in transcriptional regulation, protein methylation, and mediation of pre-mRNA splicing in cellular models.To investigate the functional roles and the prognosis potential of CARM1 alternative spliced isoforms in breast cancer, we used recently developed antibodies to detect differential CARM1 isoform expression in subcellular compartments and among malignant and benign breast tumors.Immunofluorescence in MDA-MB-231 and BG-1 cell lines demonstrated that CARM1ΔE15 is the dominant isoform expressed in the cytoplasm, and CARM1FL is more nuclear localized. CARM1ΔE15 was found to be more sensitive to Hsp90 inhibition than CARM1FL, indicating that the truncated isoform may be the oncogenic form. Clinical cancer samples did not have significantly higher expression of CARM1FL or CARM1ΔE15 than benign breast samples at the level of mRNA or histology. Furthermore neither CARM1FL nor CARM1ΔE15 expression correlated with breast cancer molecular subtypes, tumor size, or lymph node involvement.The analysis presented here lends new insights into the possible oncogenic role of CARM1ΔE15. This study also demonstrates no obvious association of CARM1 isoform expression and clinical correlates in breast cancer. Recent studies, however, have shown that CARM1 expression correlates with poor prognosis, indicating a need for further studies of both CARM1 isoforms in a large cohort of breast cancer specimens.

    Intraductal papilloma (IDP) is well-known as one of the common benign breast lesions requiring excision. However, treatment of IDP without atypia is controversial. The aim of our study was to determine the proper management of solitary IDP by core needle biopsy (CNB). We retrospectively reviewed patients with solitary IDP confirmed by CNB from March 2003 to March 2015. We collected data about final pathology after excision, as well as clinical, histologic, and radiologic findings at initial diagnosis. The final pathology was categorized as benign or malignant. We evaluated the rate of upgrade to malignancy and factors associated with malignancy. We identified 405 patients who presented benign solitary IDP by CNB. The mean age was 46.1 years (range, 15-86 years). In total, 135 patients underwent surgical excision, and 211 underwent vacuum-assisted excision. Of 346 patients, malignant lesions were found in 8 patients (2.3%): 7 underwent surgical excision, and 1 underwent vacuum-assisted excision. Only the size of IDP was significantly associated with cancer upgrade (P = .003). Our study shows that overall malignancy upgrade rate of benign solitary IDP after excision is very low (2.3%). Even when the size of IDP was less than 1 cm, the upgrade rate to cancer was only 0.9%. Therefore, for patients with small solitary IDP, we recommend close follow-up with ultrasound instead of excision. Copyright © 2017 Elsevier Inc. All rights reserved.

    The history of the radiological examination of the breast has been long, and recently the methods for examining the breast are variable: mammography, thermography, xeroradiography, ultrasonography, water-path sonography, transillumination, mammary C.T., M.R imaging, infra-red scanning, nuclear medicine, and galactography. Most of these methods were not proven or have not been satisfied on their clinical testing but conventional mammography has been the gold standard for diagnosis of the breast cancer and no other method has reached its effectiveness. The authors performed mammography in 488 patients with breast abnormalities who had visited to Yeung Nam University hospital from May, 1983 to December, 1984. And we analyzed the mammographic findings and diagnostic accuracy in pathologically confirmed 53 cases by operations or biopsies. The results are as follows: 1. Among 16 cases of breast malignancies (1) the most prevalent age group is 6th decade (37.5%), followed by 5th decade (31.3%), (2) the most common pathologic type is ductal carcinoma (93.75%), (3) the masses are larger than 2cm in 8 cases, smaller than 2cm in 5 cases, and no visible mass is observed in 3 cases. 2. Among 37 cases of benign breast diseases, (1) the most prevalent age group is 4th and 5th decades (each 11 cases), and followed by 3rd decade (8 cases), (2) the most common disease is benign tumor (17 cases), followed by fibrocystic dysplasia (13 cases), and inflammating disease (7 cases), (3) radiologically visible masses are observed in 16 cases and the masses are smaller than 2cm in 11 cases. 3. The diagnostic accuracy of mammography compared with that of pathology, (1) in malignancy, the accuracy rate is 75% (12/16 cases), and 87% (32/37 cases) in benign diseases, (2) average accuracy rate is 81% (44/53 cases)

    The capability of saliva protein analysis, based on membrane protein purification and surface-enhanced Raman spectroscopy (SERS), for detecting benign and malignant breast tumors is presented in this paper. A total of 97 SERS spectra from purified saliva proteins were acquired from samples obtained from three groups: 33 healthy subjects; 33 patients with benign breast tumors; and 31 patients with malignant breast tumors. Subtle but discernible changes in the mean SERS spectra of the three groups were observed. Tentative assignments of the saliva protein SERS spectra demonstrated that benign and malignant breast tumors led to several specific biomolecular changes of the saliva proteins. Multiclass partial least squares–discriminant analysis was utilized to analyze and classify the saliva protein SERS spectra from healthy subjects, benign breast tumor patients, and malignant breast tumor patients, yielding diagnostic sensitivities of 75.75%, 72.73%, and 74.19%, as well as specificities of 93.75%, 81.25%, and 86.36%, respectively. The results from this exploratory work demonstrate that saliva protein SERS analysis combined with partial least squares–discriminant analysis diagnostic algorithms has great potential for the noninvasive and label-free detection of breast cancer.

    2006-01-01

    Background: The effective-dose method which was proposed by the ICRP (International Commission of Radiation Protection) for the estimation of risk to the general population from occupational or environmental, low-dose radiation exposure is not adequate for estimating the risk of cancer induction by radiotherapy of malignant or nonmalignant diseases. Methods:The risk of cancer induction by radiotherapy of benign diseases should be based on epidemiologic data directly derived from follow-up studies of patients who had been given radiotherapy for nonmalignant diseases in the past. Results: Risk factors were derived from epidemiologic studies of patients treated with irradiation for nonmalignant diseases to be used for selecting treatment options and optimizing treatment procedures. Conclusion: In most cases, cancer risks estimated by the effective-dose method may overestimate the true risks by one order of magnitude, yet in other cases even may underestimate it. The proposed method using organ-specific risk factors may be more suitable for treatment planning. (orig.)

  20. Basics of Radiation Biology When Treating Hyperproliferative Benign Diseases

    Full Text Available For decades, low- and moderate-dose radiation therapy (RT has been shown to exert a beneficial therapeutic effect in a multitude of non-malignant conditions including painful degenerative muscoloskeletal and hyperproliferative disorders. Dupuytren and Ledderhose diseases are benign fibroproliferative diseases of the hand/foot with fibrotic nodules and fascial cords, which determine debilitating contractures and deformities of fingers/toes, while keloids are exuberant scar formations following burn damage, surgery, and trauma. Although RT has become an established and effective option in the management of these diseases, experimental studies to illustrate cellular composites and factors involved remain to be elucidated. More recent findings, however, indicate the involvement of radiation-sensitive targets like mitotic fibroblasts/myofibroblasts as well as inflammatory cells. Radiation-related molecular mechanisms affecting these target cells include the production of free radicals to hamper proliferative activity and interference with growth factors and cytokines. Moreover, an impairment of activated immune cells involved in both myofibroblast proliferative and inflammatory processes may further contribute to the clinical effects. We here aim at briefly describing mechanisms contributing to a modulation of proliferative and inflammatory processes and to summarize current concepts of treating hyperproliferative diseases by low and moderate doses of ionizing radiation.

    The version 3 of the guideline for radioiodine therapy for benign thyroid diseases presents first of all a revision of the version 2. The chapter indication for radioiodine therapy, surgical treatment or antithyroid drugs bases on an interdisciplinary consensus. The manifold criteria for decision making consider the entity of thyroid disease (autonomy, Graves' disease, goitre, goitre recurrence), the thyroid volume, suspicion of malignancy, cystic nodules, risk of surgery and co-morbidity, history of subtotal thyroidectomy, persistent or recurrent thyrotoxicosis caused by Graves' disease including known risk factors for relapse, compression of the trachea caused by goitre, requirement of direct therapeutic effect as well as the patient's preference. Because often some of these criteria are relevant, the guideline offers the necessary flexibility for individual decisions. Further topics are patients' preparation, counseling, dosage concepts, procedural details, results, side effects and follow-up care. The prophylactic use of glucocorticoids during radioiodine therapy in patients without preexisting ophthalmopathy as well as dosage and duration of glucocorticoid medication in patients with preexisting ophthalmopathy need to be clarified in further studies. The pragmatic recommendations for the combined use of radioiodine and glucocorticoids remained unchanged in the 3 rd version. (orig.) [de

    Breast cancer is the most common cancer in women. Prostrate-specific antigen (PSA) is a marker of prostate gland malignancy which has been considered in cases with breast cancer in recent years. The goal of this study was to determine total and free PSA levels in cases with malignant and benign breast lesions. Ninety women with histological proved malignant breast masses and 90 with benign breast masses were enrolled. Total and free PSA levels along with histological grade and conditions of vascular and perinural invasion, status of hormonal tumor receptors, immune-histo-chemistry markers recorded for all cases. Total and free PSA levels were assessed after treatment in cases with malignant masses. Total and free PSA levels were significantly higher in cases with malignant masses. The best cut off point for total PSA to differentiate benign and malignant masses was 0.31 and the best cut off point for free PSA to differentiate benign and malignant masses was 0.19. After treatment, mean free PSA level was significantly lower than free PSA before treatment (0.23 vs 0.3, pbenign and malignant breast masses.

    Full Text Available To detect the molecular changes of malignancy in histologically normal breast (HNB tissues, we recently developed a novel 117-gene-malignancy-signature. Here we report validation of our leading malignancy-risk-genes, topoisomerase-2-alpha (TOP2A, minichromosome-maintenance-protein-2 (MCM2 and “budding-uninhibited-by-benzimidazoles-1-homolog-beta” (BUB1B at the protein level. Using our 117-gene malignancy-signature, we classified 18 fresh-frozen HNB tissues from 18 adult female breast cancer patients into HNB-tissues with low-grade (HNB-LGMA; =9 and high-grade molecular abnormality (HNB-HGMA; =9. Archival sections of additional HNB tissues from these patients, and invasive ductal carcinoma (IDC tissues from six other patients were immunostained for these biomarkers. TOP2A/MCM2 expression was assessed as staining index (% and BUB1B expression as H-scores (0–300. Increasing TOP2A, MCM2, and BUB1B protein expression from HNB-LGMA to HNB-HGMA tissues to IDCs validated our microarray-based molecular classification of HNB tissues by immunohistochemistry. We also demonstrated an increasing expression of TOP2A protein on an independent test set of HNB/benign/reductionmammoplasties, atypical-ductal-hyperplasia with and without synchronous breast cancer, DCIS and IDC tissues using a custom tissue microarray (TMA. In conclusion, TOP2A, MCM2, and BUB1B proteins are potential molecular biomarkers of malignancy in histologically normal and benign breast tissues. Larger-scale clinical validation studies are needed to further evaluate the clinical utility of these molecular biomarkers.

    Background Aggressive breast cancers produce abnormal peritumoral stiff areas, which can differ between benign and malignant lesions and between different subtypes of breast cancer. Purpose To compare the tissue stiffness of the inner tumor, tumor border, and peritumoral stroma (PS) between benign and malignant breast masses by shear wave elastography (SWE). Material and Methods We enrolled 133 consecutive patients who underwent preoperative SWE. Using OsiriX commercial software, we generated multiple 2-mm regions of interest (ROIs) in a linear arrangement on the inner tumor, tumor border, and PS. We obtained the mean elasticity value (E mean ) of each ROI, and compared the E mean between benign and malignant tumors. Odds ratios (ORs) for prediction of malignancy were calculated. Subgroup analyses were performed among tumor subtypes. Results There were 85 malignant and 48 benign masses. The E mean of the tumor border and PS were significantly different between benign and malignant masses ( P benign and malignant masses. Malignant masses with a stiff rim were larger in size and associated with more aggressive pathologic subtypes.

    Objective: to study the utility of diffusion-weighted magnetic resonance imaging in the differentiation between benign and malignant breast lesions. Materials and methods: forty-five women (mean age, 46.1 years) with 52 focal breast lesions underwent diffusion-weighted magnetic resonance imaging. The calculation of apparent diffusion coefficient (ADC) was based on the ADC map reflecting five b values (0, 250, 500, 750, and 1000 s/mm 2 ). The mean ADC value of each lesion was correlated with imaging findings and histopathologic results. Cutoff ADC, sensitivity and specificity of diffusion-weighted imaging in the differentiation between benign and malignant lesions were calculated. P -3 mm 2 /s) as compared with benign lesions (1.50 ± 0.34 x 10 -3 mm 2 /s) (P < 0.0001). Diffusion-weighted imaging showed high sensitivity and specificity (both, 92.3%) in the differentiation between benign and malignant lesions. Conclusion: diffusion-weighted imaging is a potential resource as an adjuvant to breast magnetic resonance imaging to differentiate benign from malignant lesions. Such sequence can be easily added to the standard breast magnetic resonance imaging protocol, without implying any significant increase in examination time. (author)

    Aim: To evaluate the feasibility and safety of vacuum-assisted resection of benign breast tumours using an 8 G handheld device. Materials and Methods: Over a 2-year period, 22 patients with 26 breast tumours diagnosed as benign using aspiration biopsy cytology were enrolled. The mean patient age was 38 years, and the mean maximal diameter of the tumour was 13 mm. A handheld Aloka SSD 6500 ultrasonography device with a linear-type 7.5 MHz transducer was inserted into the posterior aspect of the tumour with the patient under local anaesthesia, and the tumour was resected under ultrasonographic guidance. Results: This method was employed successfully in all patients, and the mean operation time was 33 min. Post-procedure complications included subcutaneous bleeding in 12 cases and haematoma in one. The pathological diagnoses were fibroadenoma in 16 cases, mastopathy in six, and tubular adenoma and pseudoangiomatous stromal hyperplasia in two cases each, respectively. Follow-up ultrasonography revealed residual tumours in four cases (15.4%). Conclusions: Although this method is feasible and safe without severe complications, it is necessary to select appropriate patients, and to obtain informed consent regarding the possibility of recurrence or residual tumour.

    Benign thyroid disease ranks by far as the most frequent therapy in nuclear medicine. In Germany approximately 25 000 cases of hyperthyreosis are being treated in association with autonomy or Graves' disease, but also for the reduction of goiters or the correction of latent functional disturbances. In such indications radiotherapy is virtually free of risk as opposed to surgery and ranks more favorable in regard to costs and curative effects versus pharmacological long term treatment. Still regional varying therapeutical concepts and intentions are being pursued and trials of improvements described. There is consent in therapy that quality of treatment is closely linked to a specialized out-door platient preparation, individual hospital activity dosage and lifelong follow up including continued evaluation of therapeutical results. In this paper minimal requirements of outpatient measures before and after therapy are summarized which in Germany is only permitted on an inhospital patient basis. Considering basics of radioactive preventive law, scientific evidence of available results of therapeutical studies and a survey of German therapeutic centers, suggestions for a quality maintaining management in view of the most effective utilization for the limited available number of beds is presented for discussion.

    Behcet's disease is a vasculitis of unknown origin that was traditionally defined by oral and genital ulcers and uveitis. We describe a case of a patient with a diagnosis of Behcet's syndrome who presented a palpable lesion in the right breast with inflammatory signs. X-ray findings posed a differential diagnosis between tumoral and inflammatory pathology. The pathological findings confirmed a small-vessel vasculitis. We found two reports of breast involvement by this disease in the literature. Our patient was studied by mammogram and sonogram which together with clinical history are important to prevent delay in diagnosis and unnecessary therapeutic procedures. (orig.)

    To evaluate the diagnostic performance of combined B-mode sonography and ultrasound elastography for differentiation between benign and malignant breast masses with circumscribed margins. We analyzed 109 pathologically proven circumscribed breast masses. Two radiologists retrospectively reviewed B-mode sonograms and elastograms in consensus. Based on the American College of Radiology Breast Imaging Reporting and Data System, we determined categories of the masses on B-mode sonography. Elastographic scores were assessed by a 3-point scale (negative, 0; equivocal, 1; and positive, 2). When the elastographic score for a lesion was 0 or 2, we downgraded or upgraded the B-mode category, respectively; thus, the reclassified Breast Imaging Reporting and Data System category was defined as the "reclassification category." Mean category values for benign and malignant lesions were compared by a Student t test. The diagnostic performance of B-mode, elastographic, and reclassification assessments was compared by receiver operating characteristic curve analysis. The mean B-mode category (2.5 versus 1.7), elastographic score (1.7 versus 0.8), and reclassification category (3.2 versus 1.6) were significantly higher in malignant than benign lesions (P benign and malignant circumscribed breast masses, combined use of B-mode sonography and elastography could provide a better diagnostic performance than B-mode sonography alone. © 2015 by the American Institute of Ultrasound in Medicine.

    We aimed to investigate the association between a polycystic ovary syndrome (PCOS) and fibrocystic breast disease. A total of 93 women, aged between 17 and 36 years, not using oral contraceptives, were entered in this case-control study. Laboratory, clinical and ultrasound findings were used to diagnose PCOS. The study group was consisted of 53 PCOS women and the control group consisted of 40 women. Breast ultrasonography was performed for all patients. Fibrocystic breast disease is described as common benign changes involving the tissues of the breast. Twenty-one (39.6%) of 53 women with a PCOS had fibrocystic breast disease. Five (8%) of 40 controls had fibrocystic breast disease. The difference between the groups was statistically significant (p = 0.004). Relative risk (95% CIs) was 3.17 (1.31-7.68). Overall sonographic benign breast pathologies were significantly higher in the PCOS group (p = 0.036). This study showed a statistically significant association between a PCOS and fibrocystic breast disease. Women with a PCOS should be evaluated for fibrocystic breast disease.

    Full Text Available BACKGROUND Breast is modified sebaceous gland. It is an organ of female beauty and pride. From puberty to death, the breast is subjected to constant physical and physiological alterations that are related to menses, pregnancy and menopause. The breast problem could be as simple as breast abscess to as ominous as cancer. Both benign and malignant diseases occur in men and women of all ages but benign lesion tend to occur more commonly at younger age than cancer. Benign breast diseases (BBD are common with estimate of over half of the female population at some times in life seeking medical advice for breast problem. This prospective study was done on patients attending OPD for breast complaints in 1 year period, to do the risk factors assessment & clinical analysis of patients presented with breast complaints. MATERIALS AND METHODS Total 200 patients who have attended OPD with breast related complaints and given consent for study, were studied in a period of 1 year duration from at Nehru Hospital, B.R.D Medical College, Gorakhpur. RESULTS Benign breast diseases are more common in the population than malignant one, Fibroadenoma, Breast abscesses and Fibrocystic disease and ANDI are the most common cause of mass seen in middle ages. Malignant lesion of the breast is major concern and the second most commonly diagnosed cancer in our region as seen in study. Incidence is high in western industrialized countries and relatively low in developing countries in Asia and other parts of the world, predisposing factors for BBD are age, sex, race, inverted nipple, retracted nipple, cracked nipple, improper feeding due to lack of knowledge about breast-feeding and endogenous hormonal factors. CONCLUSION BBD is the most frequent type of lesion found in the present study in surgery OPD in BRD medical college, Gorakhpur. Among BBD, fibroadenoma was the commonest, followed by breast abscess, ANDI and gynecomastia. In this study, breast abscess was second most

    We explored the utility of time-resolved angiography with interleaved stochastic trajectories dynamic contrast-enhanced magnetic resonance imaging (TWIST DCE-MRI), readout segmentation of long variable echo-trains diffusion-weighted magnetic resonance imaging- diffusion-weighted magnetic resonance imaging (RESOLVE-DWI), and echo-planar imaging- diffusion-weighted magnetic resonance imaging (EPI-DWI) for distinguishing between malignant and benign breast lesions.This retrospective analysis included female patients with breast lesions seen at a single center in China between January 2016 and April 2016. Patients were allocated to a benign or malignant group based on pathologic diagnosis. All patients received routine MRI, RESOLVE-DWI, EPI-DWI, and TWIST DCE-T1WI. Variables measured included quantitative parameters (K, Kep, and Ve), semiquantitative parameters (rate of contrast enhancement for contrast agent inflow [W-in], rate of contrast decay for contrast agent outflow [W-out], and time-to-peak enhancement after contrast agent injection [TTP]) and apparent diffusion coefficient (ADC) values for RESOLVE-DWI (ADCr) and EPI-DWI (ADCe). Receiver-operating characteristic (ROC) curve analysis was used to evaluate the diagnostic utility of each parameter for differentiating malignant from benign breast lesions.A total of 87 patients were included (benign, n = 20; malignant, n = 67). Compared with the benign group, the malignant group had significantly higher K, Kep and W-in and significantly lower W-out, TTP, ADCe, and ADCr (all P benign and malignant lesions. Combining 3 parameters (Kep, W-out, and ADCr) had a higher diagnostic efficiency (AUC, 0.965) than any individual parameter and distinguished between benign and malignant lesions with high sensitivity (91.0%), specificity (95.0%), and accuracy (91.9%).An index combining Kep, W-out, and ADCr could potentially be used for the differential diagnosis of breast lesions.

    Full Text Available We present the clinical implementation of a novel hybrid system that combines magnetic resonance imaging (MRI and near-infrared (NIR optical measurements for the noninvasive study of breast cancer in vivo. Fourteen patients were studied with a MR-NIR prototype imager and spectrometer. A diffuse optical tomographic scheme employed the MR images as a priori information to implement an image-guided NIR localized spectroscopic scheme. All patients who entered the study also underwent gadolinium-enhanced MRI and biopsy so that the optical findings were crossvalidated with MR readings and histopathology. The technique quantified the oxy-and deoxyhemoglobin of five malignant and nine benign breast lesions in vivo. Breast cancers were found with decreased oxygen saturation and higher blood concentration than most benign lesions. The average hemoglobin concentration ([H] of cancers was 0.130±0.100 mM, and the average hemoglobin saturation (Y was 60±9% compared to [H]=0.018±0.005 mM and Y=69±6% of background tissue. Fibroadenomas exhibited high hemoglobin concentration [H]=0.060±0.010 mM and mild decrease in oxygen saturation Y=67±2%. Cysts and other normal lesions were easily differentiated based on intrinsic contrast information. This novel optical technology can be a significant add-on in MR examinations and can be used to characterize functional parameters of cancers with diagnostic and treatment prognosis potential. It is foreseen that the technique can play a major role in functional activation studies of brain and muscle as well.

    2015-12-01

    To provide guidelines for clinical practice from the French College of Obstetrics and Gynecology (CNGOF), based on the best evidence available, concerning common benign breast tumors: fibroadenoma (FA), phyllodes breast tumors (PBT), and papillary lesions (BPL). Bibliographical search in French and English languages by consultation of PubMed, Cochrane and international databases. In case of percutaneous biopsy diagnosis of FA, clinico-radiologic and pathologic discordance or complex FA or proliferative lesions or atypia with FA, a family history of cancer, it seems legitimate to discuss management in a multidisciplinary meeting. When surgery is proposed for FA, periareolar compared to direct incision is associated with more insensitive nipple but better aesthetic results (LE4). When surgery is proposed for FA, indirect incision is preferable for better cosmetic results (Grade C). Techniques of percutaneous destruction or resection can be used (Grade C). The WHO classification distinguishes three categories of phyllodes tumors (PBT): benign (grade 1), borderline (grade 2) and malignant (grade 3). For grade 1 PBT, the risk of local recurrence after surgical excision increases when PBT lesion is in contact with surgical limits (not in sano). After in sano resection, there is no correlation between margin size and the risk of recurrence (LE4). For grade 2 PBT, local recurrence after surgical excision increases for margins under 10mm margins (LE4). For grade 1-2 PBT, in sano excision is recommended. For grade 2 PBT, 10-mm margins are recommended (Grade C). No lymph node evaluation or neither systematic mastectomy is recommended (Grade C). Breast papillary lesion (BPL) without atypia, complete resection of radiologic signal is recommended (Grade C). For BPL with atypia, complete excisional surgery is recommended (Grade C).

    Abstract The diagnosis of solid benign and malignant tumors presents a unique challenge to all noninvasive imaging modalities. Ultrasound is used in conjunction with mammography to differentiate simple cysts from solid lesions. However, the overlapping appearances of benign and malignant lesions make ultrasound less useful in differentiating solid lesions, resulting in a large number of benign biopsies. Optical tomography using near-infrared diffused light has great potential for imaging functional parameters of 1) tumor hemoglobin concentration, 2) oxygen saturation, and 3) metabolism, as well as other tumor distinguishing characteristics. These parameters can differentiate benign from malignant lesions. However, optical tomography, when used alone, suffers from low spatial resolution and target localization uncertainty due to intensive light scattering. Our aim is to combine diffused light imaging with ultrasound in a novel way for the detection and diagnosis of solid lesions. Initial findings of two earlystage invasive carcinomas, one combined fibroadenoma and fibrocystic change with scattered foci of lobular neoplasia/lobular carcinoma in situ, and 16 benign lesions are reported in this paper. The invasive cancer cases reveal about two-fold greater total hemoglobin concentration (mean 119 µmol) than benign cases (mean 67 µmol), and suggest that the discrimination of benign and malignant breast lesions might be enhanced by this type of achievable optical quantification with ultrasound localization. Furthermore, the small invasive cancers are well localized and have wavelength-dependent appearance in optical absorption maps, whereas the benign lesions appear diffused and relatively wavelength-independent.

    2017-08-15

    As the world population becomes progressively older, the overall incidence of chronic subdural hematoma (CSDH) is increasing. Peak age of onset for CSDH has also increased, and recently the 80-year-old level has a peak. Many patients with CSDH have had prior treatment with anticoagulants and antiplatelet drugs, which have an accompanying risk of CSDH. In elderly patients with CSDH, symptoms of cognitive change (memory disturbance, urinary incontinence, and decreased activity) and disturbance of consciousness at admission were more frequent compared to younger patients with CSDH. The literature actually offers conflicting advice regarding CSDH treatment; however, burr hole surgery with drainage under local anesthesia is the most common surgical procedure, even in elderly patients. The recurrence rate of CSDH has not decreased over recent decades, and it has ranged from 0.36-33.3%. Outcomes in patients over 75 years old was significantly worse than for those younger than 75. Moreover, long-term outcomes for elderly patients with CSDH are poor. CSDH in the elderly is no longer a benign disease. In the future, it will be important for us to understand the mechanisms of onset and recurrence of CSDH and to develop more effective medical treatments and noninvasive surgical techniques for elderly patients.

    Purpose: Invasive breast carcinomas and fibroadenomas are often difficult to differentiate in dynamic contrast-enhanced T1-weighted MR imaging of the breast, because both tumors can enhance strongly after contrast injection. The purpose of this study was to evaluate whether the addition of T2*-weighted first pass perfusion imaging can increase the differentiation of malignant from benign lesions. Material and Methods: Nine patients with invasive carcinomas and 10 patients with contrast enhancing fibroadenomas were examined by a dynamic contrast-enhanced T1-weighted 3D sequence immediately followed by a single slice T2*-weighted first pass perfusion sequence positioned in the contrast-enhancing lesion. Results: The carcinomas and the fibroadenomas were impossible to differentiate based on the contrast enhancement characteristics in the T1-weighted sequence. The signal loss in the T2*-weighted perfusion sequence was significantly stronger in the carcinomas than in the fibroadenomas (p=0.0004). Conclusion: Addition of a T2*-weighted first pass perfusion sequence with a high temporal resolution can probably increase the differentiation of fibroadenomas from invasive carcinomas in contrast-enhanced MR imaging of the breast.

    We performed digital subtraction angiography (DSA) via arteries (IA-DSA) and veins (IV-DSA) on 42 patients with breast diseases to investigate its availability. The findings by DSA in cases with breast cancer included: tumor stains, hypervascularity and tortuosity, enlarged blood vessels, encasement and pooling. Metastatic lymph nodes and daughter nodules were also recognized by DSA. In benign tumors of the breast, a tumor stain was observed only in one case of fibroadenoma; otherwise no remarkable changes were noticed. The incidence of signs in cases with breast cancer using IA-DSA was 65 % for hypervascularity, 59 % for tumor stain, 41 % for vascular tortuosity and 41 % for enlargement of vessels. IV-DSA, on the contrary, revealed less incidences. However, tumor stain was seen frequently, and hypervascularity was seldom observed. The number of signs out of the abovementioned six appearing in each case was tabulated. With IA-DSA, there were 5 signs noted in 2 cases, but the majority had fewer: 4 cases in 4 cases and only 2 signs in 4 cases. There were no signs evident in 18 % of the cases. The incidence of the appearance of signs with IV-DSA was lower: there were no signs in 36 % of the cases. Therefore, the diagnostic accuracy of IA-DSA seemed to be fairly good in comparison with that of IV-DSA. The rate of appearance of abnormal signs was also examined, according to the size of the tumors. In IA-DSA, T 1 breast cancers revealed malignant signs in 80 % of the cases, in T 2 there were such signs 75 % and 100 % of the T 3 cases exhibited malignant signs, for an overall average of 82 %. In IV-DSA, T 1 showed 33 %, T 2 showed 70 %, and T 3 , 1 out of 1 case, showed malignant signs, 64 % altogether. It was the bigger the tumor, the larger the number of signs. The smallest breast cancer that exhibited abnormality in DSA was 1.0 x 0.7 cm in size. (J.P.N.)

    To evaluate the ability of shear-wave elastography (SWE) to distinguish between benign and malignant palpable masses of the adult male breast. Clinical examination, mammography, B-mode and Doppler ultrasound findings and SWE quantitative parameters were compared in 50 benign lesions (including 40 gynaecomastias) and 15 malignant lesions (invasive ductal carcinomas) from 65 patients who were consecutively addressed for specialized advice at our comprehensive cancer centre. Mean elasticity (El mean), maximum elasticity (El max), El mean of the surrounding fatty tissue and lesion to fat ratio (El ratio) were reported for each patient. Malignant masses displayed significantly higher El mean (p masses without overlap of values between the two groups. By adding SWE to clinical examination, mammography and ultrasound, all the lesions would have been retrospectively correctly diagnosed as benign or malignant. One false positive could have been downstaged, 14/65 undetermined masses could have been correctly reclassified as 4 malignant and 10 benign lesions, for which biopsies could have consequently been avoided. Evaluation of male breast palpable masses by SWE demonstrates that malignant masses are significantly stiffer lesions and may improve diagnostic management when clinical examination, mammography and conventional ultrasound are doubtful. Advances in knowledge: Quantitative SWE is feasible in male breast and could be of great interest to help classify doubtful lesions after classical clinical and radiological evaluations, probably because of different anatomy and different tumours epidemiology compared with female breast.

    The aim of this study was to evaluate the physiologic and benign F-18 fluorodeoxyglucose (FDG) avid foci in patients with breast cancer. On 309 F-18 FDG PET/CT scans of 241 women with breast cancer, the hypermetabolic lesions compared with the surrounding normal region were evaluated retrospectively. Available reports of other relevant radiological imaging medical records, and follow-up PET/CT were reviewed for explanations of the abnormal uptake. Among the 70 physiologic foci, muscular uptake of the lower neck following the surgical and/or radiation therapy of ipsilateral breast (29%), hypermetabolic ovaries (16%) and uterine (10%) uptake during the ovulatory and menstrual phases during the normal menstrual cycle were identified, and also hypermetabolic brown fat in cold-induced thermogenesis (7%), non-specific bowel uptake (35%) were observed. Among the 147 benign lesions, sequelae of the chest wall and breasts following surgical and/or radiation therapy, were often observed (27%). Hypermetabolic thyroid glands were noted as adenomas and chronic thyroiditis (18%). Reactive hyperplasia of cervical or mediastinal lymph nodes (32%), degenerative osteoarthritis and healed fractures (15%), hypermetabolic benign lung lesions (6%) were observed. Altered physiologic and benign F-18 FDG uptake in the cervical muscle and chest wall following ipsilateral breast surgery or radiotherapy were common, and also normal physiologic uptake in ovary and uterus, brown fat, thyroid were considered as predominant findings in women patients with breast cancer. Knowledge of these findings might aid in the interpretation of FDG PET/CT in patients with breast cancer

    The version 3 of the guideline for radioiodine therapy for benign thyroid diseases presents first of all a revision of the version 2. The chapter indication for radioiodine therapy, surgical treatment or antithyroid drugs bases on an interdisciplinary consensus. The manifold criteria for decision making consider the entity of thyroid disease (autonomy, Graves' disease, goitre, goitre recurrence), the thyroid volume, suspicion of malignancy, cystic nodules, risk of surgery and co-morbidity, history of subtotal thyroidectomy, persistent or recurrent thyrotoxicosis caused by Graves' disease including known risk factors for relapse, compression of the trachea caused by goitre, requirement of direct therapeutic effect as well as the patient's preference. Because often some of these criteria are relevant, the guideline offers the necessary flexibility for individual decisions. Further topics are patients' preparation, counseling, dosage concepts, procedural details, results, side effects and follow-up care. The prophylactic use of glucocorticoids during radioiodine therapy in patients without preexisting ophthalmopathy as well as dosage and duration of glucocorticoid medication in patients with preexisting ophthalmopathy need to be clarified in further studies. The pragmatic recommendations for the combined use of radioiodine and glucocorticoids remained unchanged in the 3{sup rd} version. (orig.)

    This study was performed to evaluate the mammographic and sonographic features of mass-like fibrocystic disease of the breast to differentiate from other breast mass. We retrospectively analyzed characteristics mammographic(16 cases) and sonographic findings(39 cases) of histopathologically proven mass-like fibrocystic disease of the breast in 39 patients. Of 16 patients with mammogram, mass-like fibrocystic disease of the breast was round shape in 12 cases, high density in 14 cases.The margin of the mass was well marginated in 8 cases, poorly marginated in 8 cases. The calcification within the mass was not detected in 13 cases. In 39 patients with sonogram, mass-like fibrocystic disease of the breast was mostly ovoid shape in 24 cases, hypoechoic in 23 cases, with homogenous internal echo in 36 cases, well defined in 28 cases, and with equivocal posterior shadowing in 26 cases. The T/AP ratios of the mass was not less than 1.5 in 29 cases. The bilateral edge-shadowing of the mass was not noted in 24 cases. Characteristic findings of the mass-like fibrocystic disease of the breast are round shape, high density, well defined mass on mammograrn and ovoid shape, homogeneous internal echo, well marginated mass on sonogram which were similar to those in other benign lesion. Mass-like fibrocystic disease, which in a frequent cause of breast lumps, should be included in the differential diagnosis of breast mass with benign mammographic and/or sonographic findings

    To evaluate the clinical significance of the screening mammography in the detection of the breast diseases, especially breast carcinoma. We analyzed 1,800 cases of mammography retrospectively. The mammography was done as a part of routine check in Health Counselling Center, Korea University Medical Center, during 9 months from November 1993 to July 1994. The age range was from 23 years to 76 years, mean 49.8 years, and the largest age group was 6th decade (31.4%). According to the mammographic findings, we divided the subjects into three groups; normal group, abnormal group in need of follow-up study, abnormal group requiring biopsy. On mammography, the normal group consisted of 1,534 cases (85%), and the abnormal group consisted of 266 cases (15%). The abnormal findings were benign-looking calcification (n = 140), fibroadeno ma (n = 29), fibrocystic changes (n = 27), cyst (n = 23), malignant lesion (n = 15) lipoma (n = 7), and others. In four of 15 cases, which were suspected to be malignant on mammograms, breast carcinoma was confirmed pathologically. In four cases of breast carcinoma, one was under 40 and the other 3 were over 50 years of age. All of the breast cancers were under 3 cm in size, and the mammographic findings of breast cancer included spiculated margin (n = 3), parenchymal distortion (n = 3), malignant calcification (n = 2) and enlarged axillary node (n = 1). Screening mammogram is helpful for early detection of non-palpable breast cancer, especially for women over 50 years of age

    Full Text Available BACKGROUND Breast cancer is one of the five most common types of cancer among women. Vast majority of diseases that occur in breast are benign. With the use of mammography, ultrasonography and fine needle biopsy, the diagnosis of breast diseases has become easy and also it is helping in early diagnosis of malignancy and better treatment of it. MATERIAL AND METHODS A prospective study was undertaken starting in January 2015, of the entire patient with breast disease referred to or attending the Department of General Surgery, Konaseema Institute of Medical Sciences, Amalapuram, A.P. RESULTS One hundred fifty nine new patients were included in to this study from January 2015 to May 2016. Out of one hundred fifty nine patients, biopsy/FNAC was done for one hundred five patients. Most usual final diagnosis was normal followed by benign cystic lesion that was in twenty patients. Fibroadenoma was next common diagnosis in fifteen patients. Ductal carcinoma of the breast was final diagnosis in two patients. CONCLUSION In our study, we have found that benign breast disease was most common final diagnosis, out of that fibrocystic disease was more common than fibroadenoma. Two patients were diagnosed to be duct cell carcinoma.

    All complications diagnosed at early stages of breast cancer were associated with small tumors, especially with those arising in the aftermath of fibrocystic disease. Hence, our task was to study the XR-semiotics of lesions of less than 15 mm in diameter and of the same origin. 100 mammograms of breast cancer patients with benign disease of the breast were studied. The presence of moderate-to-severe fibrocystic disease significantly affected the visualization of lesions of less than 10 mm in diameter. Since the XR-semiotics of small tumors failed to reveal malignancy features, all lesions visualized by mammography required additional diagnostic procedures using ultrasound and invasive radiology.

    To evaluate the usefulness and complications of ultrasonography (US)- guided vacuum assisted biopsy (VAB) for the removal of benign breast lesions, and the short- and long-term changes after VAB as shown on follow-up US. From January 2007 to May 2008, 110 sonographically benign lesions in 62 patients were sampled via US-guided VAB. We prospectively evaluated the sonographic findings 1 week and 6 months after VAB in all patients to determine the presence of residual tumors, hematomas and scarring. We evaluated the prevalence of hematoma, pain, skin dimpling, fibrotic scarring and residual tumors after US-guided VAB, and determined if correlation existed between complications, size of the lesions and lesion pathology. The age of the patients was 15-65 years, with a mean age of 36.5 years. The pathologic diagnoses were fibroadenomas (41.8%, n = 46), fibrocystic changes (30.9%, n = 34), fibroadenomatoid hyperplasias (13.6%, n = 15), fibroadenomatoid mastopathies (6.3%, n = 7), adenoses (3.6%, n = 4), hamartomas (1.8%, n = 2) and phyllodes tumors (1.8%, n = 2). Complications 1 week after the US-guided VAB included hematomas (n = 39, 35.4%), pain (n = 23, 20.9%), fibrotic scars (n = 26, 23.68%), residual tumors (n = 4, 3.6%) and skin dimplings (n = 4, 3.6%). Complications 6 months after the US-guided VAB included hematomas (n = 12, 10.9%), pain (n = 3 2.7%), fibrotic scars (n = 14, 12.7%), and residual tumors (n = 17, 15.4%). Residual tumor after US-guided VAB existed in association with 15.2% of fibroadenomas (7/46), 14.7% of fibrocystic changes (5/34), 13.3% of fibroadenomatoid hyperplasias (2/15), 25% of adenoses (1/4), and 100% of phyllodes tumors (2/2). US-guided VAB is an effective procedure for removal of benign breast lesion. Periodic follow up studies at 1 week and 6 months after the VAB are useful to assess Post-VAB complications

    The purpose of this study is to review various breast diseases in children and adolescents and to illustrate the sonographic findings. We reviewed the cases at our institution in order to identify breast disease in children and adolescent patients who underwent sonography and mammography. Breast disease in children and adolescents included developmental disturbance, infection, benign tumors and inherent defects. In contrast to adults, the radiologic findings of malignant breast conditions in pediatric populations have rarely been reported; however, we show ductal carcinoma in situ with juvenile fibroadenoma and rhabdomyosarcoma. During childhood and adolescence, the recognition and correct identification of physiologic breast development and specific lesions in breast entities on radiologic findings is most helpful in identifying and characterizing abnormalities and in guiding further investigation.

    The activity to be administered in I-131 therapy of benign thyroid disease is determined by the radiation absorbed dose necessary to cure the disease, the target mass, and the residence time of the I-131 in the target volume. Data from 73 patients with complete sets of uptake measurements 2, 6, 24, 48, and 96 (n = 53) or 120 (n = 20) hours after oral administration of 1 MBq I-131 were used to deduce residence times from subsets of 3, 2, or only 1 measurement for each individual. The values were compared to those obtained with the reference method, i.e. a fit of an uptake function based on a 2-compartment model to all 5 measurements, to quantify the errors introduced by the less demanding assessments. Deviations are less than 10% if the 2- compartment uptake function is fitted to only 3 values measured after 6, 24, and 96-120 h. Use of 2, 24, and 96-120 h data results in errors > 20% in individual patients. The effective half-lives as determined from 2 measurements after 24 and 96-120 h correlate well with those deduced from the reference method with larger deviations in individuals with slow iodine kinetics and late maximal uptake. Residence times determined from the 24 h uptake, assuming linear increase during the first day, and the effective half-life limited to maximum 8 days underestimate the actual values systematically in patients with long and short half-lives. These errors can be eliminated by a modification of the calculation method resulting in deviations less than 14% in all but one individual for this procedure. The accuracy of methods based on only one retention value increases with the time of measurement after the administration of I-131. While systematic errors up to a factor of two occur if the 24 h uptake is used for the estimate, deviations are less than 18% for measurements after 120 h.

    The thyroid gland was one of the first organs imaged in nuclear medicine, beginning in the 1940s. Thyroid scintigraphy is based on a specific phase or prelude to thyroid hormone synthesis, namely trapping of iodide or iodide analogues (ie, Tc99m pertechnetate), and in the case of radioactive iodine, eventual incorporation into thyroid hormone synthesis within the thyroid follicle. Moreover, thyroid scintigraphy is a reflection of the functional state of the gland, as well as the physiological state of any structure (ie, nodule) within the gland. Scintigraphy, therefore, provides information that anatomical imaging (ie, ultrasound, computed tomography [CT], magnetic resonance imaging) lacks. Thyroid scintigraphy plays an essential role in the management of patients with benign or malignant thyroid disease. In the former, the structure or architecture of the gland is best demonstrated by anatomical or cross-sectional imaging, such as ultrasound, CT, or even magnetic resonance imaging. The role of scintigraphy, however, is to display the functional state of the thyroid gland or that of a clinically palpable nodule within the gland. Such information is most useful in (1) patients with thyrotoxicosis, and (2) those patients whose thyroid nodules would not require tissue sampling if their nodules are hyperfunctioning. In neoplastic thyroid disease, thyroid scintigraphy is often standard of care for postthyroidectomy remnant evaluation and in subsequent thyroid cancer surveillance. Planar radioiodine imaging, in the form of the whole-body scan (WBS) and posttherapy scan (PTS), is a fundamental tool in differentiated thyroid cancer management. Continued controversy remains over the utility of WBS in a variety of patient risk groups and clinical scenarios. Proponents on both sides of the arguments compare WBS with PTS, thyroglobulin, and other imaging modalities with differing results. The paucity of large, randomized, prospective studies results in dependence on consensus

    In order to assess the utility of 67gallium citrate in delineating malignant pleural mesothelioma from benign asbestos-related pleural disease, 49 patients with malignant mesothelioma and 16 with benign asbestos-related pleural disease were studied. Seven patients with malignant mesothelioma had no history of asbestos exposure, while the remaining 58 patients were exposed. Forty-three of the 49 patients (88%) with malignant mesothelioma had a positive 67gallium scan including 36 of the 42 (86%) patients with asbestos exposure and all 7 patients without a history of asbestos exposure. Three of 16 patients (19%) with benign asbestos-related pleural disease had a positive scan. 67Gallium radionuclide imaging is nonspecific but may be valuable in noninvasive monitoring of asbestos-exposed populations, which have a high risk for the late development of benign and/or malignant pleural disease

    Phantoms elaboration has turned a very important field of study during the last decades due to its applications in medicine. These objects are capable of emulating or mimicking acoustically biological tissues in which parameters like speed of sound (SOS) and attenuation are successfully attained. However, these materials are expensive depending on their characteristics (USD 460.00 - 6000.00) and is difficult to have precise measurements because of their composition. This paper presents the elaboration and characterization of low cost ( USD $25.00) breast phantoms which emulate histological normality and pathological conditions in order to support algorithm calibration procedures in imaging diagnosis. Quantitative ultrasound (QUS) was applied to estimate SOS and attenuation values for breast tissue (background) and benign lesions (fibroadenoma and cysts). Results showed values of the SOS and attenuation for the background between 1410 - 1450 m/s and 0.40 - 0.55 dB/cm at 1 MHz sampling frequency, respectively. On the other hand, the SOS obtained for the lesions ranges from 1350 to 1700 m/s and attenuation values between 0.50 - 1.80 dB/cm at 1 MHz. Finally, the fabricated phantoms allowed for obtaining ultrasonograms comparable with real ones whose acoustic parameters are in agree with those reported in the literature.

    Laparoscopic surgery for benign and malignant pancreatic lesions has slowly been gaining acceptance over the past decade and is being introduced in many centres. Some studies suggest that this approach is equivalent to or better than open surgery, but randomized data are needed to assess outcomes.

    Benign proliferative epithelial disorders (BPED) of the breast are conditions which are thought to have premalignant potential. The purpose of the present investigation was to study the association between cigarette smoking and risk of BPED. The study was undertaken within the 56,837 women within Canadian National Breast Screening Study (NBSS) who completed self-administered lifestyle and dietary questionnaires. (The NBSS is a randomized controlled trial of screening for breast cancer in women aged 40-59 at recruitment.) During the course of the follow-up period, a total of 691 women in the dietary cohort were diagnosed with biopsy-confirmed incident BPED. For comparative purposes, a subcohort consisting of a random sample of 5681 women (including 65 of the subjects with BPED) was selected from the full cohort. After exclusions for various reasons, the analyses were based on 691 cases and 5443 non-cases. Overall, the results of the present study are almost uniformly null, and provide little support for an association between cigarette smoking and risk of BPED. Analyses conducted separately in the screened and control arms of the NBSS also failed to provide strong support for associations, and there was little difference between the results for screen-detected and interval-detected BPED. There was some suggestion of an increase in risk in post-menopausal ex-smokers, but the trend in risk with cigarette-years of exposure in this group was not statistically significant. Risk in ex-smokers varied little by years since smoking cessation. There was little evidence for associations with either atypical or non-atypical forms of BPED

    In this study, we evaluated the diagnostic accuracy of (99m)Tc-bombesin scintigraphy for differentiation of benign from malignant palpable breast lesions. (99m)Tc-Bombesin is a tracer with high affinity for gastrin-releasing peptide receptor, which is overexpressed on a variety of human tumors including breast carcinoma. We examined 33 consecutive women who were referred to our center with suspicious palpable breast lesions but had no definitive diagnosis in other imaging procedures. A volume of 370-444 MBq of (99m)Tc-bombesin was injected and dynamic 1-min images were taken for 20 min immediately after injection in anterior view. Thereafter, two static images in anterior and prone-lateral views were taken for 5 min. Finally, single-photon emission computed tomography images were taken for each patient. Definitive diagnosis was based on biopsy and histopathological evaluation. The scan findings were positive in 19 patients and negative in 11 on visual assessment of the planar and single-photon emission computed tomography images. Pathologic examination confirmed breast carcinoma in 12 patients with positive scans and benign pathology for 18 patients. The overall sensitivity, specificity, negative and positive predictive values, and accuracy of this radiotracer for diagnosis of breast cancer were 100, 66.1, 100, 63, and 76%, respectively. Semiquantitative analysis improved the specificity of the visual assessment from 66 to 84%. Our study showed that (99m)Tc-bombesin scintigraphy has a high sensitivity and negative predictive value for detecting malignant breast lesions, but the specificity and positive predictive value of this radiotracer for differentiation of malignant breast abnormalities from benign ones are relatively low.

    To investigate the association between overall life satisfaction and healthy lifestyle, knowledge of breast cancer, physical examination, and detection rate of breast cancer and benign breast disease in Chinese women. In a multicentered breast disease screening program in China, we enrolled 33,057 women aged 45-65 years without prior diagnosis of breast cancer. After completing an epidemiological questionnaire, all participants were examined by clinical breast examination, breast ultrasound, and mammography independently. All breast cancer cases and a selected sample of benign breast diseases were confirmed pathologically. Univariate and multivariate odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to estimate the association between life satisfaction and lifestyle, knowledge of breast cancer, physical examination, and detection rate of breast diseases. Overall life satisfaction was positively associated with women's healthy lifestyle. Compared with less satisfied women, satisfied women were less likely to be smokers (OR = 0.54; 95% CI: 0.47-0.62), have more exercise (OR = 1.49; 95% CI: 1.26-1.75), eat less fried (OR = 0.60; 95% CI: 0.50-0.71), smoked (OR = 0.54, 95% CI: 0.47-0.63), pickled (OR = 0.66, 95% CI: 0.55-0.79), and grilled (OR = 0.63, 95% CI: 0.54-0.74) foods. Satisfied women were more likely to have knowledge of breast cancer (OR = 1.48, 95% CI: 1.29-1.70), and have regular physical examinations (OR = 1.11, 95% CI: 1.01-1.12). Compared to less satisfied women, we found significantly lower detection rate of benign breast diseases (OR = 0.90, 95% CI: 0.82-0.99), and lower but nonsignificant detection rate of breast cancer (OR = 0.66, 95% CI: 0.35-1.25) in satisfied women. Women with a higher overall life satisfaction are more likely to have healthy lifestyle, knowledge of breast cancer, and regular physical examination, thus resulting in a lower detection rate of breast diseases in screening. © 2015 The Authors.

    Malignant melanoma is one of the most rapidly increasing cancer in the world. Breast metastases from melanoma are uncommon but could reflect a widespread disease. We report a case of malignant widespread melanoma presenting with bilateral breast nodules in a 39 year-old pre-menopausal Caucasian woman with an history of cutaneous melanoma of the trunk. Breast clinical examination revealed the presence of a hard and mobile lump located on the left breast. Ultrasound detected two bilateral nodules corresponding to oval opacities with well-defined edges and without calcifications or architectural distortion on mammography. Fine needle aspiration cytology performed on both breast nodules confirmed that the breast lesions were metastases from primary cutaneous malignant melanoma. A total-body CT examination detected brain, lung and abdominal lymph nodes metastases. The breast represents an uncommon site of metastatic disease from extra-mammary tumors. Imaging features of breast metastases from melanoma usually do not allow a differential diagnosis with breast primary tumors. Breast metastases may be asymptomatic or palpable as dense and well-circumscribed nodules. Breast metastases indicate a widespread disease and should lead to avoid aggressive surgical procedures because of the poor prognosis of patients affected by metastatic melanoma. The detection of bilateral breast metastases from melanoma is highly suggestive of metastatic multi-organ disease and could be useful to address the therapeutic approach.

    Radioiodine therapy of benign thyroid diseases (focal = [toxic adenoma], multifocal, disseminated autonomy, Grave's disease or clinical relevant goitre) needs to be and can be performed individually for each patient. Most frequently a radioiodine test is performed applying a small activity of iodine-131 ({sup 131}I). The paper discusses some protocols for pre- or posttherapeutic dosimetry and discusses their advantages and disadvantages. All are based on the volumetry of the target tissue as well as the radioiodine kinetics in the target volume what may be represented by maximum uptake and half life of iodine retention in the thyroid. Possible disturbances and measuring uncertainties of these parameters are presented and discussed. In spite of the discussed uncertainties in dosimetry, due to its high therapeutic width radioiodine therapy is a very successful procedure to cure hyperthyroidism or to reduce goitre volume with only little side effects.

    Seven men with unilateral nipple discharge underwent galactography. In two patients the diagnosis was carcinoma, two were benign papillomas, one was a breast abscess, and two were ductal ectasia. Galactography is useful in men and women with nipple discharge, especially when the discharge is bloody and there is no palpable tumor. The precise location of an intraductal lesion through the use of galactography guides the biopsy and makes conservative surgery easier.

    The presence or absence of myoepithelial cells (ME) has been considered as an important feature in the differential diagnosis of benign and malignant papillary lesions of the breast. We evaluated the distribution of myoepithelial cells in formalin-fixed paraffin-embedded tissue sections of 25 papillomas and 18 papillary carcinomas by ABC immunoperoxidase technique with antibodies to muscle actin (HHF-35) and high molecular weight (HMW) keratin (clone 34BE12, cytokeratins 1, 5, 10, and 14; reacting preferentially with ME cells) and an antiserum to S-100 protein. Also included in the study were eight cases of micropapillary ductal carcinoma in situ (DCIS) having a few fibrovascular cores and five peripheral papillomas with accompanying ductal carcinoma in situ or atypical hyperplasia. The antibodies to muscle actin were sensitive and relatively specific for ME cells of the breast and uniformly labeled ME cells in all 25 papillomas. ME cells were absent or extremely sparse in papillary carcinomas. They were present focally in some of the fibrovascular cores of the micropapillary DCIS, and a mixed pattern was observed in peripheral papillomas with areas of carcinoma. HMW keratin was variably expressed in ME cells in most cases with positive internal controls and was present in several normal ductal and papilloma epithelial cells but not in epithelial cells of papillary carcinomas. HMW keratin, although less specific for ME cells, was a useful adjunct because of its reactivity with ME cells as well as hyperplastic epithelial cells in papillomas, which resulted in a combined positive reaction.(ABSTRACT TRUNCATED AT 250 WORDS)

    Breast cancer is the most common female malignancy worldwide. Pakistan has the highest incidence rate of breast cancer than any other Asian population. The purpose of the study was to evaluate the worth of sono-mammography in diagnosis of symptomatic breast diseases by comparing it with mammogram. Methods: In this cross-sectional validation study, 45 subjects with mean age of 45+-12.07 were included. Majority of the patients presented with complaint of breast lump. After complete history and clinical examination, all the patients had high resolution ultrasound of bilateral breasts and axilla followed by bilateral mammography. Histopathology was taken as gold standard in this study. The exclusion criteria were pregnancy and patients having direct clinical signs of breast malignancy. Results: Based on histopathology, out of 45 patients with breast symptoms, 12 patients had benign lesions, whereas 32 patients were diagnosed as the cases of breast cancers. Finally one patient did not have biopsy proven final diagnosis. Sensitivity and specificity of ultrasound were calculated to be 100% and 67% as compared to sensitivity and specificity of 90.6% and 91.7% for that of mammography. Conclusions: Ultrasound is a useful complementary tool to mammography in assessment of symptomatic breast diseases since it helps in characterization and localization of breast lesions seen on mammogram and it is not limited by dense breasts. Also it should be the considered as initial imaging technique for assessment of palpable breast lumps. (author)

    Radiomics features extracted from breast lesion images have shown potential in diagnosis and prognosis of breast cancer. As clinical institutions transition from 1.5 T to 3.0 T magnetic resonance imaging (MRI), it is helpful to identify robust features across these field strengths. In this study, dynamic contrast-enhanced MR images were acquired retrospectively under IRB/HIPAA compliance, yielding 738 cases: 241 and 124 benign lesions imaged at 1.5 T and 3.0 T and 231 and 142 luminal A cancers imaged at 1.5 T and 3.0 T, respectively. Lesions were segmented using a fuzzy C-means method. Extracted radiomic values for each group of lesions by cancer status and field strength of acquisition were compared using a Kolmogorov-Smirnov test for the null hypothesis that two groups being compared came from the same distribution, with p-values being corrected for multiple comparisons by the Holm-Bonferroni method. Two shape features, one texture feature, and three enhancement variance kinetics features were found to be potentially robust. All potentially robust features had areas under the receiver operating characteristic curve (AUC) statistically greater than 0.5 in the task of distinguishing between lesion types (range of means 0.57-0.78). The significant difference in voxel size between field strength of acquisition limits the ability to affirm more features as robust or not robust according to field strength alone, and inhomogeneities in static field strength and radiofrequency field could also have affected the assessment of kinetic curve features as robust or not. Vendor-specific image scaling could have also been a factor. These findings will contribute to the development of radiomic signatures that use features identified as robust across field strength.

    Previous studies have not showed consistent results for the level of expression of sodium/iodide symporter (NIS) in thyroid diseases, especially malignant tumor. We undertook this study to evaluate the distribution of NIS expression in malignant thyroid diseases and compare with that in benign thyoid disease. Total patients were 119 cases (Men 15, 48±13 yrs). Total number of samples were 205 pieces. In malignant thyroid disease, there were 153 samples: 90 in papillary carcinoma, 4 in follicular carcinoma, 2 in medullary carcinoma and 57 in metastatic lymph node. In benign thyroid disease, there were 52 samples: 36 in goiter/cyst, 11 in thyroiditis and 5 in follicular adenoma. Using immunohistochemical methods, we probed 205 samples with monoclonal anti-NIS Ab. Grading of staining was scored as 0 (negative or absent), 1 (weakly positive), 2 (moderately positive) or 3 (strongly positive). Expression rate (ER) of NIS positivity in individual disease entity was expressed as percentage of total number divided by number in 2 plus 3 grade. ERs of malignant thyroid diseases were 63% in papillary carcinoma, 81% in metastatic lymph node, 71% in follicular carcinoma and 100% in medullary carcinoma. ERs of benign thyroid disease were 53% in goiter/cyst, 64% in thyroiditis and 40% in follicular adenoma. ER of benign thyroid deceases was higher than benign thyroid diseases (71% vs 54%). Grading of NIS expression in papillary carcinoma or goiter/cyst was heterogeneously distributed in considerable cases. Normal tissue also showed heterogeneous distribution or NIS expression, which was not correlated with that of primary lesion. In papillary thyroid carcinoma, distribution of NIS expression was heterogeneous and increased, and not different compared with that of benign thyroid disease

    To compare the galactographic findings of malignant and benign disease in patients with pathologic nipple discharge and to analyze the features suggesting malignancy. In 24 patients in whom pathologic nipple discharge had occurred, the findings of preoperative galactography were correlated with those of pathology. Nine of the 24 cases were malignant and the other 15 were benign. Intraductal calcification occurred in five malignant cases (56%) and two (13%) which were benign. Seven malignant cases (78%) involved the segmental ducts, and in eight (89%), the peripheral ducts below the subsegmental duct were involved. Five benign cases (33%) involved the lactiferous sinus, seven (47%) the segmental duct, and two (13%) the subsegmental duct. Distal duct dilatation occurred in four benign cases (27%), while ductal stenosis was noted in six cases (67%) and ductal distortion in seven (78%). A malignant tumor appeared as a multiple (n=5, 56%) or irregular (n=5, 56%) filling defect, and a benign tumor as a single (n=12, 80%), oval (n=6, 40%) or lobular (n=4, 27%) filling defect. At galactography, a malignant tumor frequently appeared as an irregular multiple intraductal filling defect in a peripheral duct. A benign tumor, on the other hand, appeared as an oval or lobular single lesion. The presence of ductal stenosis, distortion and intraductal microcalcifications not opacified by contrast material suggest possible malignancy.

    The characteristics of type II microcalcifications in fibroadenoma (FB), atypical ductal hyperplasia (ADH), and ductal carcinoma in situ (DCIS) breast tissues has been analyzed by the fingerprint features of Raman spectroscopy. Fresh breast tissues were first handled to frozen sections and then they were measured by normal Raman spectroscopy. Due to inherently low sensitivity of Raman scattering, Au@SiO2 shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS) technique was utilized. A total number of 71 Raman spectra and 70 SHINERS spectra were obtained from the microcalcifications in benign and premalignant breast tissues. Principal component analysis (PCA) was used to distinguish the type II microcalcifications between these tissues. This is the first time to detect type II microcalcifications in premalignant (ADH and DCIS) breast tissue frozen sections, and also the first time SHINERS has been utilized for breast cancer detection. Conclusions demonstrated in this paper confirm that SHINERS has great potentials to be applied to the identification of breast lesions as an auxiliary method to mammography in the early diagnosis of breast cancer.

    To compare the diagnostic values of retraction phenomenon in the coronal planes and descriptors in the Breast Imaging Reporting and Data System-Ultrasound (BI-RADS-US) lexicon in differentiating benign and malignant breast masses using an automated breast volume scanner (ABVS). Two hundred and eight female patients with 237 pathologically proven breast masses (120 benign and 117 malignant) were included in this study. ABVS was performed for each mass after preoperative localization by conventional ultrasonography (US). Multivariate logistic regression analysis was performed to assess independent variables for malignancy prediction. Diagnostic performance was evaluated through the receiver operating characteristic (ROC) curve analysis. Retraction phenomenon (odds ratio [OR]: 76.70; 95% confidence interval [CI]: 12.55, 468.70; P<0.001) was the strongest independent predictor for malignant masses, followed by microlobulated margins (OR: 55.87; 95% CI: 12.56, 248.44; P<0.001), angular margins (OR: 36.44; 95% CI: 4.55, 292.06; P=0.001), calcifications (OR: 5.53; 95% CI: 1.34, 22.88; P=0.018,) and patient age (OR: 1.10; 95% CI: 1.03, 1.17; P=0.004). Mass shape, orientation, echo pattern, indistinct margins, spiculated margins, and mass size were not significantly associated with breast malignancy. Area under the ROC curve (Az) for microlobulated margins and retraction phenomenon was higher than that for other significant independent predictors. Az, sensitivity, and specificity were 0.877 (95% CI: 0.829, 0.926) and 0.838 (95% CI: 0.783, 0.892), 82.9% and 70.1%, and 92.5% and 98.3%, respectively, for microlobulated margins and retraction phenomenon. Retraction phenomenon and microlobulated margins have high diagnostic values in the differentiation of benign and malignant breast masses using an ABVS. Copyright © 2015 Elsevier Ireland Ltd.

    Diseases of the mandible affect the soft tissues aside from the osseous manifestation. This can be shown clearly and in great detail by magnetic resonance imaging (MRI). MRI is the gold standard in the diagnostic evaluation of any internal derangement of the temporomandibular joint. Dental MRI requires high resolution techniques and in some cases also intravenous administration of contrast material. These techniques allow delineation of the neurovascular bundle. In the past few years new indications were formulated, for example, the evaluation of the integrity of the inferior alveolar nerve in trauma and in radicular cysts. New quantitative methods now enable insights into the pathophysiology. The objective of this review is to communicate accepted indications for MRI of the mandible and to present innovative applications. (orig.)

    Most references in the literature on interventional radiology of the biliary tract refer to the treatment of cancer; only occasionally are benign conditions mentioned. An updated list of radiosurgical instruments on the market in Italy is presented. The operating technique from the preparation of the patient to the performance of percutaneous transhepatic cholangiography (PTC), biliary drainage, transhepatic bilioplasty, percutaneous extraction and chemical cholelitholisis of biliary calculi and drainage of biliary collections is then described. A personal series is then presented. It consist of 93 patients in whom one or more of the following conditions were diagnosed: exclusively intrahepatic calculosis (3 cases), calculosis of the common bile duct (23 percutaneous treatments), empyema of the gallbladder (6 cases), suppurating cholangitis (46 cases), sclerotic or inflammatory stenosis (16 cases), biliary collections (14 cases). Results are reported and commented on

    The aim of this study was to compare three devices in percutaneous excisional biopsy of clinically benign breast lesions in terms of complete excision rate, duration of procedure and complications. In a retrospective study from March 2005 to May 2009, 983 lesions underwent ultrasound-guided excisional biopsy with three vacuum-assisted systems, respectively. The lesions were category 3 lesions as determined by ultrasound imaging according to Breast Imaging Reporting and Data System (BI-RADS) (n=951) or had been confirmed as benign by a previous core needle biopsy (n=32). The completely excision rate, duration of procedure and complications (hematoma, pain and ecchymosis) were recorded. 99.7% (980/983) lesions were demonstrated to be benign by pathology after percutaneous excisional biopsy. The overall complete excision rate was 94.8% (932/983). In lesions whose largest diameter equal to or larger than 1.5cm, the complete excision rates of EnCor(®) group (97.8%, 348/356) and Mammotome(®) group (97.2%, 139/143) were significantly higher than that of Vacora(®) group (91.9%, 445/484) (P<0.05). The EnCor(®) group (6.6±6.5min) had a significant less duration than Mammotome(®) (10.6±9.3min) and Vacora(®) group (25.6±23.3min) (P<0.05). Hematoma occurred more in EnCor(®) group and Mammotome(®) group than in Vacora(®) group (P<0.05). All these three vacuum-assisted systems are highly successful for excisional biopsy of benign breast lesions. Copyright © 2011 Elsevier Ireland Ltd. All rights reserved.

    Background and objective: To examine whether clinically benign multiple sclerosis patients (BMS) show similar losses of their global N-acetylaspartate (NAA) neuronal marker relative to more clinically disabled patients of similar disease duration. Methods: The whole-brain NAA concentration (WBNAA) was acquired with whole-head non-localizing proton MR spectroscopy. Fractional brain parenchymal volume (fBPV), T 2 and T 1 lesion loads, were obtained from the MRI in: (i) 24 BMS patients: 23.1 ± 7.2 years disease duration, median Expanded Disability Status Scale (EDSS) score of 2.0 (range: 0–3); (ii) 26 non-benign MS patients (non-BMS), 24.5 ± 7.4 years disease duration, median EDSS of 4.0 (range: 3.5–6.5); (iii) 15 healthy controls. Results: Controls’ 12.4 ± 2.3 mM WBNAA was significantly higher than the BMS's and non-BMS's 10.5 ± 2.4 and 9.9 ± 2.1 mM (both p < 0.02), but the difference between the patients’ groups was not (p > 0.4). Likewise, the controls’ 81.2 ± 4.5% fBPV exceeded the BMS and non-BMS's 77.0 ± 5.8% and 76.3 ± 8.6% (p < 0.03), which were also not different from one another (p > 0.7). BMS patients’ T 1 -hypointense lesion load, 2.1 ± 2.2 cm 3 , was not significantly different than the non-BMS's 4.1 ± 5.4 cm 3 (p > 0.08) and T 2 -hyperintense loads: 6.0 ± 5.7 cm 3 and 8.7 ± 7.8 cm 3 , were also not different (p > 0.1). Conclusions: WBNAA differentiates normal controls from MS patients but does not distinguish BMS from more disabled MS patients of similar disease duration. Nevertheless, all MS patients who remain RR for 15+ years suffered WBNAA loss similar to the average RR MS population at fourfold shorter disease duration suggesting relative global neuronal sparing or leveling-off of the neurodegeneration rate

    This study was performed to evaluate the diagnostic utility of quantitative analysis of benign and malignant breast lesions using contrast-enhanced sonography. Contrast-enhanced sonography using the perflubutane-based contrast agent Sonazoid (Daiichi Sankyo, Tokyo, Japan) was performed in 94 pathologically proven palpable breast mass lesions, which could be depicted with B-mode sonography. Quantitative analyses using the time-intensity curve on contrast-enhanced sonography were performed in 5 region of interest (ROI) types (manually traced ROI and circular ROIs of 5, 10, 15, and 20 mm in diameter). The peak signal intensity, initial slope, time to peak, positive enhancement integral, and wash-out ratio were investigated in each ROI. There were significant differences between benign and malignant lesions in the time to peak (P benign and malignant lesions in the time to peak (P benign and malignant breast lesions. © 2015 by the American Institute of Ultrasound in Medicine.

    This study was performed to compare the diagnostic performance of power Doppler ultrasound (US) and a new microvascular Doppler US technique (AngioPLUS; SuperSonic Imagine, Aix-en-Provence, France) for differentiating benign and malignant breast masses. Power Doppler US and AngioPLUS findings were available in 124 breast masses with confirmed pathologic results (benign, 80 [64.5%]; malignant, 44 [35.5%]). The diagnostic performance of each tool was calculated to distinguish benign from malignant masses using a receiver operating characteristic curve analysis and compared. The area under the curve showed that AngioPLUS was superior to power Doppler US in differentiating benign from malignant breast masses, but the difference was not statistically significant. © 2018 by the American Institute of Ultrasound in Medicine.

    A number of benign and malignant diseases may cause pleural abnormalities. Since the resolution of computed tomography (CT) has been improved, the detailed anatomy of pleura can now be well delineated in various pleural diseases. We reviewed retrospectively the CT findings of 60 patients with pathologically proved pleural diseases in order to find out the differential points between benign and malignant diseases. Thirty-six patients had malignant diseases (20 adenocarcinoma, 8 squamous cell carcinoma, 4 small cell carcinoma, 2 lung metastasis, 1 large cell carcinoma, 1 small and large cell carcinoma), and 24 patients had benign diseases (16 tuberculosis including empyema, 3 bacterial empyema, 3 pneumonia, 1 lung abscess, 1 lung contusion). The CT features that suggested malignant pleural diseases were high-grade mediastinal involvement (57.9%, {rho} < 0.1), thick and irregular thickening with nodularity and mass formations (38.5%, {rho} < 0.1), Circumferential pleural thickening 132.1%, {rho} < 0.01), and aggressive pleural effusion 122.2%, {rho} < 0.05). Benign pleural lesions were typically represented by pleural calcification (50%) and extrapleural fat accumulation (45.8%)

    One of the most specific and critical regulators of angiogenesis is vascular endothelial growth factor (VEGF), which regulates endothelial proliferation, permeability, and survival. Vascular endothelial growth factor is an angiogenic mediator in tumors and has been implicated in the pathogenesis and progression of cancer. Adipose tissue is a major endocrine and it secretes hormones termed adipokines. These factors are derived from adipocytes and include proteins and metabolites such as adiponectin. Recently, adiponectin was also shown to modulate angiogenesis. This study was designed to determine the serum VEGF and adiponectin levels in patients with benign and malignant gynecological diseases and if there was a correlation between serum VEGF and adiponectin. Serum samples, collected fasting before surgery or intervention, were available for total of 114 female patients recorded between October 2006 and December 2008. Diagnosis of benign and malignant gynaecological diseases was established by biopsy. Serum levels VEGF and adiponectin were using commercially available enzyme linked immunosorbent assay (R&D Systems Inc, Minneapolis, MN), respectively. Statistical analysis was performed by using the SPSS 9.0 software package (SPSS, Inc, Chicago, IL). The correlation between serum VEGF and serum Adiponectin was calculated using the Pearson correlation coefficient. P values of benign and malignant gynecological diseases of the patient. Only for serum VEGF levels was a significant difference observed (P = 0.004) between patients with benign and malignant gynecological diseases. A significantly inverse correlation between serum VEGF and adiponectin levels among patients with benign and malignant gynecological diseases was found. Adiponectin level is not correlated with body mass index. This is one of the first report on adiponectin in benign and malignant gynecological diseases. Future studies are needed to address the clinical potential role of adiponectin in cancer.

    Aim: To investigate the capability and diagnostic accuracy of diffusion-weighted imaging (DWI) in differentiating benign from malignant breast lesions using 3 T magnetic resonance imaging (MRI). Materials and methods: Women with suspicious or indeterminate breast lesions detected at MRI, mammogram and/or ultrasound were recruited for dynamic contrast-enhanced (DCE)-MRI and DWI prior to their biopsy. Image fusion of DCE-MRI with apparent diffusion coefficient (ADC) map was utilized to select the region of interest (ROI) for ADC calculation in the area that showed the most avid enhancement. DWI was performed using two sets of b-values at 500 and 1000 s/mm 2 , respectively. Results: Fifty women were recruited and the final analysis comprised 44 breast lesions, 31 of which were malignant and 13 were benign. Significant results were obtained between ADC values of benign and malignant lesions (p −3 mm 2 /s for b = 500 s/mm 2 and 1.22 × 10 −3 mm 2 /s for b = 1000 s/mm 2 , respectively. The sensitivity of DCE-MRI alone was 100% with a specificity of 66.7%. When DCE-MRI was combined with b = 1000 s/mm 2 , the specificity rose to 100%, while only mildly affecting sensitivity (90.6%). No significant correlation was found between ADC values and prognostic factors, such as lymph node metastasis, tumour size, oestrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) status, and tumour grades. Conclusion: The present study provides consistent evidence to support DWI as a diagnostic tool for breast lesion characterization. A combination of DCE-MRI with DWI is suggested to improve the sensitivity and specificity of lesion characterization

    Bactibilia has several consequences to human health. Assessing the bile microbiology of patients with biliopancreatic diseases in order to identify bacteria and their possible infectious complications. Retrospective study of 30 bile culture samples from patients with benign and malignant biliopancreatic diseases. The samples were assessed to set the bile microbiological flora and to search for its possible link with comorbidity, carcinogenesis and postoperative infectious complications. Thirty bile samples from patients at mean age ≈57.7 years, mostly female (n=18), were assessed. Bactibilia was found in 12 cases, mostly in patients with benign diseases (n=8), older than 50 years (n=23) and female (n=10). Adenocarcinoma of the duodenal papilla (n=9) and cholelithiasis (n=8) were the most common diseases. Escherichia coli (n=5) and Klebsiella sp (n=3) were predominantly found in patients with benign diseases; and Klebsiella sp (n=2) and Streptococcus sp (n=2) were prevalent in cancer patients. There were postoperative infectious complications in seven cases, five of them in bactibilia-associated patients (P=0.084). Bactibilia was found in 12 samples and Escherichia coli and Klebsiella sp were most often identified in patients with benign diseases, as well as Streptococcus sp and Klebsiella sp in cancer patients. There was a trend of higher postoperative infectious complication incidence in patients with bactibilia.

    The study deals with methods of treatment of benign thyroid affections: diffuse hyperthyroidism, autonomous adenoma, euthyreotic struma. 70% of the patients examined require resective therapy for diffuse hyperthyroidism. In the majority of the cases radio-iodine resection is the method to be chosen. The risk of an eventual X-ray cancer is smaller than the operation mortality. As far as children and adolescents are concerned, 131-iodine therapy is generally not advisable because of the carcinogenic risk which might be heightened. The autonomous adenoma can be eliminated without any problems by using 131-iodine. In case of a large adenoma with considerable regressive changes operation should be preferred. The therapeutic measures in the case of a struma mainly depend on the question if there are any clinical symptoms or any signs indicating an increased risk of malignancy. In case of mechanical complaints caused by a struma nodosa without important regressive changes parenchyma can be reduced by administering 131-iodine once or several times. The reduction of the thyroid function to the middle or lower limit of the normal range in case of euthyreosis is carried out by 131-iodine administration. (GSE) [de

    In this paper, we evaluate the radiological features of pregnancy-associated breast lesions and discuss the difficulties in diagnosis by imaging. We selected patients who were diagnosed with pregnancy-associated breast lesions during the previous 5 years. All patients complained of palpable lesions in the breast and underwent ultrasonographic (US) examination, the first choice for examination of pregnancy-related breast lesions. Any suspicious lesions found by the US were recommended for a US-guided core biopsy, US-guided fine needle aspiration (FNA), or surgery. Various breast lesions were detected during pregnancy and lactation, including breast cancer, mastitis and abscesses, lactating adenoma, galactoceles, lobular hyperplasia, and fibroadenomas. The imaging features of pregnancy-associated breast lesions did not differ from the features of non-pregnancy-associated breast lesions; however, some pregnancy-associated benign lesions had suspicious sonographic features. A US-guided core biopsy was necessary for differentiating benign from malignant. In patients with breast cancer, the cancer was often advanced at the time of diagnosis. In conclusion, various pregnancy-related breast lesions were detected and the imaging of these lesions had variable findings. Breast ultrasound could be an excellent imaging modality for diagnosis and differentiation between benign and malignant lesions. However, when the imaging results are suspicious, a biopsy should be performed to obtain a pathologic diagnosis.

    Objective: To evaluate the value of diffusion-weighted imaging (DWI) in the differential diagnosis of benign and malignant breast lesions with Meta-analysis. Methods: English and Chinese articles published from 1997 to 2007 were searched in Cochrane library, Pubmed, Ovid, Elsevier, Springer databases and Chinese National Knowledge Infrastructure (CNKI), and selected according to the criteria for diagnostic research recommended by Cochrane Method Group. The characteristics of selected articles including the study background, design, results and diagnostic indicators were analyzed. Statistical analysis was performed with Meta-test version 0.9. Results: Six articles were included with a total of 479 lesions. The sensitivity and specificity of DWI for breast lesions ranged from 64.0% to 92.8% and from 45.8% to 96.7% respectively. All groups had homogeneity, and a fixation effects regression was developed. The pooled weighted sensitivity and specificity with 95% CI and Az was 86% (76%-92%), 80% (61%-91%) and 92.19% respectively. Sensitivity analysis demonstrated no remarkable change on heterogeneity. Conclusion: The value of ADC in DWI can help to differentiate the benign breast lesions from the malignant with good sensitivity and specificity. The further study is needed to assess the clinical application of the b-value and diagnostic threshold. (authors)

    The study was to explore diagnostic value of the virtual touch tissue imaging quantification (VTIQ) in distinguishing benign and malignant breast lesions of variable sizes. We performed conventional ultrasound and VTIQ in 139 breast lesions. The lesions were categorized into three groups according to size (group 1, ≤ 10 mm; group 2, 10-20 mm; and group 3, > 20 mm), and their mean, min, and max shear wave velocities (SWVs) were measured. Diagnoses were confirmed by pathological examination after surgery or needle biopsy. Receiver-operating characteristic curves (ROC) were constructed to determine the optimum cut-off values, calculate the area under curve (AUC), the sensitivity, specificity and accuracy for each velocity. For all groups, the mean, min, and max SWVs of malignant lesions were significantly higher than those of benign lesions (P < 0.05). The cut-off values of mean, min, and max SWVs were not significantly different among the three groups. In addition, the diagnostic performance of mean, min, and max SWV values is analogous, regardless of lesion size. In conclusion, VTIQ is a strong complement to conventional ultrasound, which is a promising method in the differential diagnosis of the breast lesions with different sizes. Further studies validate our results as well as reduce the number of unnecessary biopsies, regardless of size is warranted. PMID:26550234

    Loss of heterozygosity (LOH), a genetic change frequently detected in cancer, can also occur in benign epithelial foci in the breast. To characterize LOH in benign breast tissue, 32 cases containing the various components of fibrocystic change in the absence of malignancy were studied. Microdissected foci of ductal hyperplasia, apocrine metaplasia, sclerosing adenosis, and morphologically normal terminal duct lobular units (TDLUs) were analyzed for LOH at 14 polymorphic loci representing seven chromosomal arms. LOH was detected in 22% of normal TDLUs (6/27), 17% of adenosis (4/23), 19% of hyperplasia (4/21), and 53% of apocrine metaplasia (10/19) specimens. Because of the high percentage of LOH in apocrine metaplasia in nonneoplastic specimens, the genetic relationship between apocrine metaplasia and cancer was studied in a panel of breast cancer cases. Of 14 examples of apocrine metaplasia adjacent to a carcinoma, seven were found to have LOH with at least one marker. In all seven cases, the tumor and apocrine metaplasia shared LOH at one or more markers. The results demonstrate that LOH occurs frequently in the components of fibrocystic change as well as in normal TDLUs and suggest that foci of apocrine metaplasia can share a genetically altered precursor cell with an associated carcinoma.

    Acoustic radiation force impulse imaging (ARFI) with Virtual Touch™ tissue quantification (VTTQ) enables the determination of shear wave velocity (SWV) in meters per second (m/s). The aim of our study was to describe the mean SWV in normal breast tissue and various breast masses. We performed measurements of SWV with ARFI VTTQ in 145 breast masses (57 malignant, 88 benign) and in the adjacent breast parenchyma and adipose tissue. The mean SWV as well as the rate of successful measurements were analyzed. The difference between adipose tissue and parenchyma was statistically significant (3.05 versus 3.65 m/s) (P breast masses, numerous measurements exceeded the upper limit of possible measurement (≥9.10 m/s, indicated as "X.XX m/s"). Nevertheless, the difference between the malignant and benign masses was statistically significant (8.38 ± 1.99 m/s versus 5.39 ± 2.95 m/s) (P < 0.001). The best diagnostic accuracy (75.9%) was achieved when the cutoff point for malignancy was set to 9.10 m/s in ARFI VTTQ. This implies that the SWV was regarded as suspicious when the upper limit of possible measurement was exceeded and the machine returned the value X.XX m/s. In conclusion, ARFI VTTQ is a feasible method for measurement of SWV in a region of interest. Furthermore, we propose the event of a highly elevated SWV as a significant criterion for malignancy. However, the method is technically not yet fully developed, and the problem of unsuccessful measurements must still be solved.

    Objective: To differentiate malignant and degenerative benign bone disease using 99m Tc- citrate scintigraphy. Methods: Thirty-nine patients (92 lesions) with confirmed malignant bone disease or degenerative benign bone disease were studied, for which the results of 99m Te-methylene diphosphonate( 99m Tc- MDP) scintigraphy were positive. 99m Tc-citrate scintigraphy was performed within a time interval of 2-7 days after 99m Tc-MDP scintigraphy. Visual analysis and semiquantitative analysis were applied. Each lesion was scored as malignant or benign, which was independently verified, using conventional techniques (histopathology, X-ray, CT, MRI and clinical follow up). Results: In visual analysis of 99m Tc-citrate imaging, most malignant lesions (35/48, 72.92%) clearly showed high radioactivity accumulation, while most benign lesions (39/44, 88.64%) had not obviously visible uptake of 99m Tc-citrate. In semiquantitative analysis of 99m Tc- citrate image, malignant lesions demonstrated a higher lesion-to-background radioisotope uptake ratio (RUR) than that of benign degenerative lesions (1.47 ± 0.42 vs. 1.09 ± 0.38, t=2.887, P 99m Tc-MDP in the two groups is of the same (1.96 ± 0.25 vs. 1.87 ± 0.21, t=1.178, P>0.20). Conclusion: 99m Tc- citrate scintigraphy is a promising method to differentiate malignant from benign degenerative lesions seen as areas of increased activity on 99m Tc-MDP bone scintigraphy.

    The clinical usefulness of mammography in postmenopausal women was evaluated by conducting a ''vertical'' analysis using indexes of sensitivity and specificity, and a separate ''horizontal'' analysis assessing the relationship between the mammographic test result and the occurrence of specific clinical management decisions. The patients included 105 women with breast cancer, 104 women with fibrocystic breast disease, and 103 women with clinically benign breasts. The study confirmed the generally accepted high values reported for the sensitivity and for the specificity of mammography as a test for breast cancer, while also helping to reconcile the widely varying indexes of test efficacy reported in some studies. The authors also observed that physicians' management decisions vary according to the mammographic interpretation, and include such distinctive clinical strategies as watchful expectancy (observe and follow), repeated mammograms, or breast biopsy. Future studies will need to determine reasons for specific management decisions, especially when they appear to contradict authoritative recommendations

    Full Text Available Abstract Background Hepato-biliary tract lithiasis is common and present either as pain or as asymptomatic on abdominal ultrasonography for other causes. Although the DNA of Helicobacter species are identified in the gallbladder bile, tissue or stones analyzed from these cases, still a causal relationship could not be established due to different results from different geographical parts. Methods A detailed search of pubmed and pubmedcentral was carried out with key words Helicobacter and gallbladder, gallstones, hepaticolithiasis, cholelithiasis and choledocholithiasis, benign biliary diseases, liver diseases. The data was entered in a data base and meta analysis was carried out. The analysis was carried out using odds ratio and a fixed effect model, 95% confidence intervals for odds ratio was calculated. Chi square test for heterogeneity was employed. The overall effect was calculated using Z test. Results A total of 12 articles were identified. One study used IgG for diagnosis while others used the PCR for Ure A gene, 16 S RNA or Cag A genes. A couple of studies used culture or histopathology besides the PCR. The cumulative results show a higher association of Helicobacter with chronic liver diseases (30.48%, and stone diseases (42.96%(OR 1.77 95% CI 1.2–2.58; Z = 2.94, p = 0.003, the effect of each could not be identified as it was difficult to isolate the effect of helicobacter due to mixing of cases in each study. Conclusion The results of present meta analysis shows that there is a slight higher risk of cholelithiasis and benign liver disease (OR 1.77, however due to inherent inability to isolate the effect of stone disease from that of other benign lesions it is not possible to say for sure that Helicobacter has a casual relationship with benign biliary disease or stone disease or both.

    To determine the utility of short-interval follow-up after benign concordant MRI-guided breast biopsy. Institutional review board approved, retrospective review of consecutive biopsies performed over 3 years (2007-10) yielded 170 women with 188 lesions that were considered benign concordant. Indication for original study, biopsy results, follow-up recommendations, compliance and outcomes of subsequent MRI and mammography examinations were reviewed. The most common indication for breast MRI was high-risk screening 119/170 (70 %). Overall, 59 % of lesions (113/188) had follow-up MRI. Of those lesions (n = 113), 43 % (49/113) presented within 7 months, 26 % (29/113) presented within 8-13 months, 11.5 % (13/113) presented within 14-22 months, and 19 % (22/113) presented after 23 months. At initial follow-up, 37 % of lesions were stable and 61 % were decreased in size. Three lesions were recommended for excision based on follow-up imaging with one malignancy diagnosed 2 years following biopsy. One additional patient had MRI-detected bilateral cancers remote from the biopsy site 3 years after biopsy. Overall cancer yield of lesions with follow-up MRI was 0.9 % (1/113); no cancers were detected at 6 months. Our data suggests that 6-month follow-up may not be required and that annual screening MRI would be acceptable to maintain a reasonable cancer detection rate. (orig.)

    Objective: To study the uptake of the 18 F-FDG in the benign pulmonary diseases with dual head SPECT coincidence detection system. Methods: Scanning were performed with dual head SPECT coincidence detection system for patients with pulmonary diseases,the uptake and the imaging characteristic of the diseases were analysed. Results: 1) In 28 tuberculosis (TB) patients, 19 cases with a negative imaging (68%, 19/28), whereas 9 cases with a positive result (32%, 9/28). The T/N value of the TB is 1.7 +- 1.2, but the T/N of the lung cancer is 4.1 +- 2.4, significantly different from them. In the skin PPD test, 9 cases with positive scans showed a 16.2 (12 - 22) mm diameter red spot, but 7 cases of negative scans with a 8.6 (0 - 15) mm diameter, both also have a significant difference. 2) Out of the 8 patients suffered from sarcoidosis, among them 5 active stage with positive scans, whereas another 3 remission cases with negative results. 3) In 18 inflammation cases, positive imagings were showed in 6 patients with cryptococcosis, mycoplasma pneumonia, mycosis, organized pneumonia, lung abscess and bacteria pneumonia. Conclusions: In some benign pulmonary diseases, 18 F-FDG imaging can be positive also. Analysing the characteristic of the imaging could rise specificity in lung cancer and also give some new clues to treatment of these benign pulmonary diseases

    To evaluate the diagnostic performance of conventional ultrasound, compression elastography (CE) and acoustic radiation force impulse imaging (ARFI) in differential diagnosis of benign and malignant breast tumors. A total of 98 patients with liver lesions were included in the study. The images of conventional ultrasound, CE and the values of virtual touch tissue quantification (VTQ) of breast lesions were obtained. The diagnostic performance of conventional ultrasound, CE and ARFI were assessed by using pathology as the gold standard, and then evaluate the diagnosis efficiency of these three approaches in differential diagnosing benign and malignant breast tumors. The specificity, sensitivity and accuracy in the diagnosis of malignant breast tumors for conventional ultrasound were 80.0%, 81.1% and 81.7%, respectively, whereas for CE elastic score were 85.7%, 86.7% and 86.3%, respectively. With a cutoff value of 3.71 for the SR, the sensitivity, specificity, accuracy in diagnosis of malignant breast tumors were 97.1%, 83.3% and 88.4%, respectively. With a cutoff value of 3.78 m/s for VTQ, the sensitivity, specificity, accuracy in diagnosis of malignant breast tumors were 94.3%, 91.7% and 92.6%, respectively. The difference in diagnosis efficiency among ARFI, CE and conventional ultrasound in differential diagnosis of benign and malignant breast tumors was significant (Pbenign and malignant breast tumors. But the diagnosis efficiency of ARFI is superior to CE and conventional ultrasound. The three approaches can help each other in differential diagnosis of benign and malignant breast tumors.

    The authors present an update version of the indications for radiotherapy in the management of benign diseases. This is based on available randomized trials and recent international meetings. Validated indications remain the prevention of resected heterotopic bone ossifications, keloids scars and pterygium and also treatment of arteriovenous malformations; the place of radiotherapy for malignant exophthalmia is more and more restricted. Randomized trials have demonstrated the efficacy of endo-brachytherapy in the prevention of restenosis after angioplasty but the use of embedded stent has replaced this indication. Macular degeneration is no more an indication of radiotherapy. Quality requirements for radiotherapy are identical for benign or malignant indications. (author)

    Follow-up MRI can be useful to confirm a benign diagnosis after MRI-guided breast biopsy. This retrospective study was undertaken to evaluate appropriate timing and imaging interpretation for the initial follow-up MRI when a benign, concordant histology is obtained using MRI-guided breast biopsy. Retrospective review was performed of 177 lesions visualized only by MRI in 172 women who underwent 9-gauge, vacuum-assisted core biopsy and marker placement with imaging-concordant benign histology. All underwent follow-up MRI within 12 months. Timing of the follow-up study, change in size, results of second biopsy if performed, and distance of localizing marker to the lesion on the follow-up study were recorded. At initial follow-up, 155 lesions were decreased or gone, 14 lesions were stable, and eight were enlarged. Seventeen (9.6%, 17/177) lesions underwent a second biopsy, including six enlarging, 10 stable, and one decreasing. Of these, four were malignant. Enlargement was seen in two carcinomas at 6 and 12 months. Two carcinomas, one stable at 2 months and another stable at 3 and 11 months, were rebiopsied because of suspicion of a missed lesion in the former and worrisome mammographic and sonographic changes in the latter. The distance of the marker from the lesion on follow-up did not correlate with biopsy accuracy. Follow-up MRI did not detect missed cancers because of lesion enlargement before 6 months after biopsy; two of four missed cancers were stable. The localizing marker can deploy away from the target despite successful sampling.

The aim of our study was to describe the mean SWV in normal breast tissue and various breast masses. We performed measurements of SWV with ARFI VTTQ in 145 breast masses (57 malignant, 88 benign and in the adjacent breast parenchyma and adipose tissue. The mean SWV as well as the rate of successful measurements were analyzed. The difference between adipose tissue and parenchyma was statistically significant (3.05 versus 3.65 m/s (P < 0.001. Focusing on breast masses, numerous measurements exceeded the upper limit of possible measurement (≥9.10 m/s, indicated as "X.XX m/s". Nevertheless, the difference between the malignant and benign masses was statistically significant (8.38 ± 1.99 m/s versus 5.39 ± 2.95 m/s (P < 0.001. The best diagnostic accuracy (75.9% was achieved when the cutoff point for malignancy was set to 9.10 m/s in ARFI VTTQ. This implies that the SWV was regarded as suspicious when the upper limit of possible measurement was exceeded and the machine returned the value X.XX m/s. In conclusion, ARFI VTTQ is a feasible method for measurement of SWV in a region of interest. Furthermore, we propose the event of a highly elevated SWV as a significant criterion for malignancy.

    Surgery such as digestive tract reconstruction is usually required for pancreatic trauma and severe pancreatitis as well as malignant pancreatic lesions. The most common digestive tract reconstruction techniques (e.g., Child's type reconstruction) for neoplastic diseases of the pancreatic head often encompass pancreaticojejunostomy, choledochojejunostomy and then gastrojejunostomy with pancreaticoduodenectomy, whereas these techniques may not be applicable in benign pancreatic diseases due to an integrated stomach and duodenum in these patients. In benign pancreatic diseases, the aforementioned reconstruction will not only increase the distance between the pancreaticojejunostomy and choledochojejunostomy, but also the risks of traction, twisting and angularity of the jejunal loop. In addition, postoperative complications such as mixed fistula are refractory and life-threatening after common reconstruction procedures. We here introduce a novel pancreaticojejunostomy, hepaticojejunostomy and double Roux-en-Y digestive tract reconstruction in two cases of benign pancreatic disease, thus decreasing not only the distance between the pancreaticojejunostomy and choledochojejunostomy, but also the possibility of postoperative complications compared to common reconstruction methods. Postoperatively, the recovery of these patients was uneventful and complications such as bile leakage, pancreatic leakage and digestive tract obstruction were not observed during the follow-up period.

    Convolutional neural networks (CNNs) are the state-of-the-art deep learning network architectures that can be used in a range of applications, including computer vision and medical image analysis. It exhibits a powerful representation learning mechanism with an automated design to learn features directly from the data. However, the common 2D CNNs only use the two dimension spatial information without evaluating the correlation between the adjoin slices. In this study, we established a method of 3D CNNs to discriminate between malignant and benign breast tumors. To this end, 143 patients were enrolled which include 66 benign and 77 malignant instances. The MRI images were pre-processed for noise reduction and breast tumor region segmentation. Data augmentation by spatial translating, rotating and vertical and horizontal flipping is applied to the cases to reduce possible over-fitting. A region-of-interest (ROI) and a volume-of-interest (VOI) were segmented in 2D and 3D DCE-MRI, respectively. The enhancement ratio for each MR series was calculated for the 2D and 3D images. The results for the enhancement ratio images in the two series are integrated for classification. The results of the area under the ROC curve(AUC) values are 0.739 and 0.801 for 2D and 3D methods, respectively. The results for 3D CNN which combined 5 slices for each enhancement ratio images achieved a high accuracy(Acc), sensitivity(Sens) and specificity(Spec) of 0.781, 0.744 and 0.823, respectively. This study indicates that 3D CNN deep learning methods can be a promising technology for breast tumor classification without manual feature extraction.

    We evaluated the characteristics of the benign and malignant nodules on transrectal ultrasound in diagnosis of prostatic disease. Histologic examination of the trans perineal prostatic biopsy of the total 47 cases resulted in 19 cases of BPH, 8 cases of prostatic cancer, and 20 cases of normal prostatic tissue group. The hypoechoic mass in peripheral zone on TRUS had high possibility of prostatic carcinoma and the isoechoic or mixed echogenic mass in central gland had high possibility of benign lesion. Hypoechoic haloes around nodules and cysts were noted in BPH and normal prostatic tissue group, that were compatible with benign lesion. The mean value of PSA was 12.0 ng/ ml in BPH, 8.5 ng / ml in normal prostatic tissue group, and 65.6 ng / ml in prostatic cancer, which was very high in prostatic cancer. Between BPH and normal prostatic tissue group, there was no demonstrable difference in location of nodule, pattern of calcification, and echogenicity of the nodules on TRUS. The size of prostatic gland was relatively smaller and mean value of PSA was lower in normal prostatic tissue group, compared with in BPH. In conclusion, the location of the nodules and PSA value are considered to be important in differentiation of the benign and malignant prostatic nodules

    Full Text Available Background. To validate feasibility, efficacy, and safeness of laparoscopic treatment of benign adnexal diseases through a single transumbilical access (LESS in a prospective series of patients. Methods. A prospective clinical trial including 30 women has been conducted at the Division of Gynecology of Catholic University of Sacred Hearth of Rome. Patients underwent different laparoscopic procedures by LESS utilizing a multiport trocar and conventional straight laparoscopic instrumentation. Intra and perioperative outcome has been reported. Results. Ten mono/bilateral adnexectomies and 20 cystectomies have been performed by LESS approach. Laparoscopic procedures were completed through a single access in 28 cases (93.4%. No major intra- or postoperative complications were observed. Mean hospital stay was 1.3 days. Conclusions. LESS approach is feasible to treat benign adnexal disease with a very low conversion rate and no early or late complications. More clinical data are needed to confirm these advantages compared to standard laparoscopic technique.

    Kindermann, G; Sebicke, E

    1977-12-01

    Benign circumscribed cutaneous lymphadenosis of the areola of the nipple (Bäfverstedt's disease) occurs in children and adults. We observed 11 cases: 3 men, 3 children and 6 women. The areola undergoes rapid swelling and becomes red. At times the nipple itself is included. Unilateral enlargment and distortion of the nipple area becomes apparent. Sometimes this is associated with a tumor-like infiltration of the retro-mammillary tissue. In Contradistinction to Pagets disease of the nipple and to a mammillary adenoma there is no eczema and no ulceration. The clinical features and the typical pruritic course establish the diagnosis. Healing is spontaneous, but protracted. The aetiology is probably of an inflammatory nature. Treatment with short courses of antibiotics and anti-inflammatory agents resulted in a faster reduction of the cutaneous signs and corroborated the clinical diagnosis. We consider surgical treatment as unnecessary because circumscript benign lymphadenosis of the nipple area has a harmless course.

    Temporary placement of self-expandable stents has been increasingly used for the management of benign esophageal diseases. To evaluate the safety of endoscopic removal of esophageal self-expandable stents placed for the treatment of benign esophageal diseases. Multicenter retrospective study. Six tertiary care centers in the United States and Europe. A total of 214 patients with benign esophageal diseases undergoing endoscopic stent removal. Endoscopic stent removal. Endoscopic techniques for stent removal, time to stent removal, and adverse events related to stent removal. A total of 214 patients underwent a total of 329 stent extractions. Stents were mainly placed for refractory strictures (49.2%) and fistulae (49.8%). Of the removed stents, 52% were fully covered self-expandable metal stents (FCSEMSs), 28.6% were partially covered self-expandable metal stents (PCSEMSs), and 19.5% were self-expandable plastic stents. A total of 35 (10.6%) procedure-related adverse events were reported, including 7 (2.1%) major adverse events. Multivariate analysis revealed that use of PCSEMSs (P stent removal. Favorable factors for successful stent removal were FCSEMSs (P ≤ .012) and stent migration (P = .010). No significant associations were found for stent indwelling time (P = .145) and stent embedding (P = .194). Retrospective analysis, only tertiary care centers. With an acceptable major adverse event rate of 2.1%, esophageal stent removal in the setting of benign disease was found to be a safe and feasible procedure. FCSEMSs were more successfully removed than self-expandable plastic stents and PCSEMSs. Adverse events caused by stent removal were not time dependent.

    Purpose To compare the diagnostic utility of an investigational optoacoustic imaging device that fuses laser optical imaging (OA) with grayscale ultrasonography (US) to grayscale US alone in differentiating benign and malignant breast masses. Materials and Methods This prospective, 16-site study of 2105 women (study period: 12/21/2012 to 9/9/2015) compared Breast Imaging Reporting and Data System (BI-RADS) categories assigned by seven blinded independent readers to benign and malignant breast masses using OA/US versus US alone. BI-RADS 3, 4, or 5 masses assessed at diagnostic US with biopsy-proven histologic findings and BI-RADS 3 masses stable at 12 months were eligible. Independent readers reviewed US images obtained with the OA/US device, assigned a probability of malignancy (POM) and BI-RADS category, and locked results. The same independent readers then reviewed OA/US images, scored OA features, and assigned OA/US POM and a BI-RADS category. Specificity and sensitivity were calculated for US and OA/US. Benign and malignant mass upgrade and downgrade rates, positive and negative predictive values, and positive and negative likelihood ratios were compared. Results Of 2105 consented subjects with 2191 masses, 100 subjects (103 masses) were analyzed separately as a training population and excluded. An additional 202 subjects (210 masses) were excluded due to technical failures or incomplete imaging, 72 subjects (78 masses) due to protocol deviations, and 41 subjects (43 masses) due to high-risk histologic results. Of 1690 subjects with 1757 masses (1079 [61.4%] benign and 678 [38.6%] malignant masses), OA/US downgraded 40.8% (3078/7535) of benign mass reads, with a specificity of 43.0% (3242/7538, 99% confidence interval [CI]: 40.4%, 45.7%) for OA/US versus 28.1% (2120/7543, 99% CI: 25.8%, 30.5%) for the internal US of the OA/US device. OA/US exceeded US in specificity by 14.9% (P < .0001; 99% CI: 12.9, 16.9%). Sensitivity for biopsied malignant masses was 96

    Carcinoembryonic antigen (CEA) was determined in the sera of 452 patients with benign liver diseases by radioimmunoassay (CEA-RIA Kit, Abbott). The CEA-level exceeded 2.5 ng/ml in 39 percent and 5.0 ng/ml in 9 percent of the cases. Independent influences of age, nicotin, and alcohol consumption and connective tissue proliferation of the liver on the CEA level were demonstrated and quantified by two- and higher-dimensional contingency table analysis. Toxic liver diseases were combined with elevated serum CEA values more often than inflammatory diseases. This aspect could not be investigated independently since there were only a few cases of toxic liver diseases without alcohol consumption. Sex and relative body weight do not seem to affect the CEA level. Additional diseases of the gastrointestinal tract or the cardiovascular system did not influence the serum CEA level in liver diseases. Therefore, in patients with benign liver diseases, an elevated serum CEA level indicates increased proliferation of the connective tissue. Age, nicotin, and alcohol consumption have to be considered independently in the clinical judgement of elevated serum CEA levels, irrespective of the underlying disease. (orig.) [de

  2. The results of the radioiodine-therapy of benign thyroid diseases respecting the applied radiation dose

    1994-09-01

    452 patients with benign thyroid diseases had been explored after 6 weeks, 6 months, 1 year, 5 years and 10 years after undergone radioiodine treatment retrospectively with regard to the applied radiation dose. A relevant relation between the radiation dose and the rate of hypothyroidism could only be proved as a tendency. Treating hyperthyroidism with radioiodine, the rates of hypothyroidism after therapy were not caused by significantly higher radiation doses. Therefore suggestions to change the used radiation-doses basically cannot be made. The applied doses of radiation are sufficient to achieve a rather satisfactory effect in healing hyperthyroidism. Cases of malignancy after radioiodine therapy could not be found in this population. The effective half-life determination before therapy can be neglected, because there was found a significant difference between the pre-therapeutically estimated half-life and the post-therapeutically measured effective half-life of radioiodine. Instead, fixed values of effective half-life should be used for each group of benign thyroid diseases. The radiation therapy still seems to be an efficient treatment to cure benign thyroid diseases with rare side effects. It also can be applied to patients below the age of 40. Generally it is an alternative to drug-therapy or surgery, always considering the individual relation between gain and risk. In this respect good results can be obtained and a relapse of hyperthyroidism is hardly to expect. (author)

    We previously found that expression of the vasopressin gene is a common feature of human breast cancer. In the present study we first examined 21 different cases of benign fibrocystic breast disease for vasopressin expression using immunohistochemistry and antibodies directed against vasopressin (anti-VP) and against vasopressin-associated glycopeptide (anti-VAG). All cases examined were negative for vasopressin gene expression using these antibodies. Alternatively, we examined 16 cases of breast ductal carcinoma in situ (DCIS) using the second of these antibodies (anti-VAG), and all of these cases were positive for vasopressin gene expression. Our results suggest that products of vasopressin gene expression are not markers of cellular proliferation in the breast, and might rather represent an early part of the carcinogenic process in this tissue.

    Several techniques are being investigated as a complement to screening mammography, to reduce its false-positive rate, but results are still insufficient to draw conclusions. This initial study explores time domain diffuse optical imaging as an adjunct method to classify non-invasively malignant vs benign breast lesions. We estimated differences in tissue composition (oxy- and deoxyhemoglobin, lipid, water, collagen) and absorption properties between lesion and average healthy tissue in the same breast applying a perturbative approach to optical images collected at 7 red-near infrared wavelengths (635-1060 nm) from subjects bearing breast lesions. The Discrete AdaBoost procedure, a machine-learning algorithm, was then exploited to classify lesions based on optically derived information (either tissue composition or absorption) and risk factors obtained from patient’s anamnesis (age, body mass index, familiarity, parity, use of oral contraceptives, and use of Tamoxifen). Collagen content, in particular, turned out to be the most important parameter for discrimination. Based on the initial results of this study the proposed method deserves further investigation.

    Shear-wave elastography (SWE) has the potential to improve diagnostic performance of conventional ultrasound (US) in differentiating benign from malignant breast masses. To investigate false positive or negative results of SWE in differentiating benign from malignant breast masses and to analyze clinical and imaging characteristics of the masses with false SWE findings. From May to October 2013, 166 breast lesions of 164 consecutive women (mean age, 45.3 ± 10.1 years) who had been scheduled for biopsy were included. Conventional US and SWE were performed in all women before biopsy. Clinical, ultrasonographic morphologic features and SWE parameters (pattern classification and standard deviation [SD]) were recorded and compared with the histopathology results. Patient and lesion factors in the "true" and "false" groups were compared. Of the 166 masses, 118 (71.1%) were benign and 48 (28.9%) were malignant. False SWE features were more frequently observed in benign masses. False positive rates of benign masses and false negative rates of malignancy were 53% and 8.2%, respectively, using SWE pattern analysis and were 22.4% and 10.3%, respectively, using SD values. A lesion boundary of the masses on US (P = 0.039) and younger patient age (P = 0.047) were significantly associated with false SWE findings. These clinical and ultrasonographic features need to be carefully evaluated in performance and interpretation of SWE examinations. © The Foundation Acta Radiologica 2014.

    Around 200,000 breast disorders are annually diagnosed all over the world. Fibrocystic changes are the most common breast disorder and fibroadenoma is the most prevalent benign breast tumor. The present study aimed to determine the spectrum, type and prevalence of breast masses in women referred to Shiraz University of Medical Sciences between 2004 and 2012 . A cross-sectional study was conducted on the diagnostic reports data. A total of 640 samples were studied. Most 57.3% of masses were detected in the left breast, 65%, 28.2% and 6.1% of cases presenting with benign, malignant, and inflammatory lesions, respectively. Among all the samples the most prevalent diagnosis (37.7%) was fibroadenoma and fibrocystic lesions (17%). 174 samples (96% of the malignant cases) were invasive. 6.5% of the benign, and 37% of the malignant cases occurred in post menopause women and the differences were statistically significant. Among those with malignant tumors lymph nodes were involved in 25.6% of menopausal women and 44.2% of non-menopausal ones, and the difference was statistically significant. Regular clinical breast examination beside mammographic follow-ups, especially during menopause, should be carried out as a priority and a national organized program should be designed for screening breast disorders.

    To verify the frequency of swallowing complaints in patients with benign nonsurgical thyroid disease and compare the self-perception of swallowing disorder intensity between different types of thyroid disease. The study sample comprised 39 women aged 19-58 years (38.54 ± 10.74) with hypothyroidism (n=22; 56.4%) or thyroid nodules (n=17; 43.6%). Presence and type of swallowing complaint and self-perception of swallowing disorder intensity were investigated by means of self-ratings recorded on a 100-millimeter visual analog scale. The data were analyzed by descriptive measures and the Mann-Whitney nonparametric test was used to compare the self-perception of swallowing disorder intensity between both clinical diagnoses of thyroid disease. The level of 5% was adopted for statistical significance. Twenty-six (66.7%) individuals reported the following swallowing complaints: pharyngolaryngeal stasis sensation (37.15%), chocking (34.29%), and odynophagia (28.57%). The mean value of self-perception of swallowing disorder intensity by the visual analog scale was 59.35 (± 27.38) millimeters. No difference in self-perception was reported between the clinical diagnoses of thyroid disease. In this sample, swallowing complaint was frequently observed in patients with benign nonsurgical thyroid disease. Moderate self-perception of swallowing disorder intensity was reported regardless of the clinical diagnosis of thyroid disease.

    Objective: To investigate the diagnostic value of internal septation for differentiating benign from malignant breast lesions. Methods: A total of 26 patients were included in the study, in which 12 patients had 20 lesions of breast carcinoma and 14 patients had 25 lesions of fibroadenoma diagnosed either pathologically or clinically. The differential diagnoistic value of the hypointensive internal septation was analyzed. Results: The signal intensity of fibroadenomas and malignant lesions on T 2 -weighted fat-suppressed images could be classified as iso- to hyper- intensity, hypointensity and mixed intensity. According to the signal intensity classification, there were 5, 11 and 4 cases in patients with breast carcinoma respectively, while 11, 10, 4 cases in patients with fibroadenoma respectively. There was no statistical difference in the distribution between the two patient groups (χ 2 =1.764, P=0.414). The shape of fibroadenomas and malignant lesions could be classified as irregular, roundish or lobulated. According to the morphological classification, there were 12, 7 and 1 case in patients with breast carcinoma respectively, while 1, 7, 17 cases in patients with fibroadenoma respectively. There was statistical difference in the distribution between the two patient groups (χ 2 =23.262, P=0.000). The typical features of fibroadenomas were as follows: lobulated shape, hypointensive internal septations on T 2 -weighted or postcontrast images. The diagnostic sensitivity of the three imaging features for fibroadenoma was 68%(17/25), 52%(13/25), and 72%(18/25) respectively; and the diagnostic specificity was 95%(19/20), 90%(18/20), 95% (19/20) respectively. Conclusion: The internal septation is a rather specific sign for diagnosis of fibroadenomas. (authors)

    The aim of the study was evaluate the 3.0 T magnetic resonance (MR) perfusion imaging scanning time window following contrast injection for differentiating benign and malignant breast lesions and to determine the optimum scanning time window for increased scanner usage efficiency and reduced diagnostic adverse risk factors. A total of 52 women with breast abnormalities were selected for conventional MR imaging and T1 dynamic-enhanced imaging. Quantitative parameters [volume transfer constant (K trans ), rate constant (K ep ) and extravascular extracellular volume fraction (V e )] were calculated at phases 10, 20, 30, 40 and 50, which represented time windows at 5, 10, 15, 20 and 25 min, respectively, following injection of contrast agent. The association of the parameters at different phases with benign and malignant tumor diagnosis was analyzed. MR perfusion imaging was verified as an effective modality in the diagnosis of breast malignancies and the best scanning time window was identified: i) Values of K trans and K ep at all phases were statistically significant in differentiating benign and malignant tumors (P0.05); ii) values of V e in benign tumors increased with phase number, but achieved no obvious changes at different phases in malignant tumors; iii) the optimum scanning time window of breast perfusion imaging with 3.0 T MR was between phases 10 and 30 (i.e., between 5 and 15 min after contrast agent injection). The variation trend of V e values at different phases may serve as a diagnostic reference for differentiating benign and malignant breast abnormalities. The most efficient scanning time window was indicated to be 5 min after contrast injection, based on the observation that the V e value only had statistical significance in diagnosis at stage 10. However, the optimal scanning time window is from 5 to 15 min following the injection of contrast agent, since that the variation trend of V e is able to serve as a diagnostic reference.

    Purpose: To evaluate the incidence, histology, risk factors, treatment, and prognosis of breast cancer occurring after Hodgkin's disease. Materials and Methods: Sixty-five cases of breast cancer in 61 survivors of Hodgkin's lymphoma were analyzed. The median age at treatment for Hodgkin's disease was 24.1 [range (R): 13.3 - 71.8] years. Fifty-one percent had received radiotherapy alone, 47% radiation and chemotherapy, and 2% chemotherapy only. Relative and absolute risks were calculated based on 47 invasive breast cancers in 1049 women treated for Hodgkin's disease at Stanford. Results: The median age at diagnosis of breast cancer was 41.9 (R: 23.0 - 79.1) years; 76% of women were premenopausal. The median interval between Hodgkin's disease and breast cancer was 17.6 (R: 1.5 - 32.7) years with an increasing incidence beginning eight years after radiotherapy. The current relative risk of invasive breast cancer following Hodgkin's disease is 4.7 [95% confidence interval (CI): 3.4 - 6.1] with an absolute risk of 29.5 (CI: 18.8 - 40.2) excess cases per 10,000 person-years. Eighty-seven percent of breast cancers occurred in or at the margin of a prior radiotherapy field where a mean dose of 43.5 (R: 24.0 - 51.0) Gy was delivered. There was a family history of breast cancer in 31% of women. Cancers were detected by self examination (66%), screening mammography (27%), and physician examination (7%). Many tumors (60%) were located in the upper outer quadrants, corresponding to the axillary portion of a mantle field. There were seven cases of carcinoma in situ: six DCIS and one LCIS. The histologic distribution of invasive tumors paralleled that reported in the general population: 4% pure lobular, 35% high grade ductal, 45% intermediate grade ductal, 7% low-grade ductal, 4% tubular, 2% medullary, and 2% mucinous. Estrogen receptors were positive in 59% of evaluable cases. While 90% of invasive tumors were smaller than four centimeters, 96% were managed with mastectomy

    Ovarian cancer is the seventh most common cancer in women and the most frequent cause of gynaecological malignancy-related mortality in women. Currently, no standardized reliable screening test exists. MicroRNA profiling has allowed the identification of signatures associated with diagnosis, prognosis and response to treatment of human tumours. The aim of this study was to determine if a microRNA signature could distinguish between malignant and benign ovarian disease. A training set of 5 serous ovarian carcinomas and 5 benign serous cystadenomas were selected for the initial experiments. The validation set included 20 serous ovarian carcinomas and 20 benign serous cystadenomas. The serum\\/plasma focus microRNA Exiqon panel was used for the training set. For the validation set a pick and mix Exiqon panel, which focuses on microRNAs of interest was used. A panel of 4 microRNAs (let-7i-5p, miR-122, miR-152-5p and miR-25-3p) was significantly down regulated in cancer patients. These microRNAs target WNT signalling, AKT\\/mTOR and TLR-4\\/MyD88, which have previously been found to play a role in ovarian carcinogenesis and chemoresistance. let-7i-5p, miR-122, miR-152-5p and miR-25-3p could act as diagnostic biomarkers in ovarian cancer.

    To assess clinical variables that may be useful in differentiating gynaecomastia from carcinoma and to analyse the contribution of mammography and ultrasound to the evaluation of male breast disease. All men who underwent mammography and/or ultrasound between 1993 and 2006 in our hospital were retrospectively evaluated. Clinical characteristics in patients with gynaecomastia and those with carcinoma were compared. Radiological findings were classified according to the BI-RADS (Breast Imaging Reporting and Data System) criteria. The diagnostic performance of physical examination, mammography and ultrasound was determined and compared. A total of 628 patients with 518 mammograms and 423 ultrasounds were reviewed. The final diagnoses were: 19 carcinomas, 526 gynaecomastias, 84 other benign conditions and 25 normal. There were statistically significant differences in age, bilateral involvement, clinical presentation and physical examination between patients with carcinoma and those with gynaecomastia. The diagnostic performance of physical examination was lower than that of mammography and ultrasound (p < 0.05 for specificity). Mammography was the most sensitive (94.7%) and ultrasound the most specific (95.3%) for detection of malignancy (p > 0.05). We propose an algorithm for the use of mammography and ultrasound in men. Mammography and ultrasound, with a negative predictive value close to 100%, make it possible to avoid very many unnecessary surgical procedures in men. (orig.)

  15. The Rare Benign Lesion That Mimics a Malignant Tumor in Breast Parenchyma: Nodular Fasciitis of the Breast

    2018-01-01

    Full Text Available We herein report the clinical and pathological findings of a rare case of nodular fasciitis in the breast parenchyma of a 48-year-old female. Because of potentially malignant findings on ultrasonography and during clinical examination, the patient underwent an excisional biopsy. Histologically, the lesion was composed of spindle to round shaped cells arranged in short bundles in a storiform pattern. Immunohistochemically, the cells were positive for vimentin and SMA and negative for desmin, S100, and CD34. Based on these morphological and immunohistochemical features, a diagnosis of nodular fasciitis was made. We emphasize that nodular fasciitis of the breast may show clinical features and imaging findings similar to those of breast cancer. The histopathologic diagnosis of nodular fasciitis can also be challenging. The purpose of this case report is to highlight the characteristics and the differential diagnosis of this rare neoplasm.

    Stromal factors have been identified as important for tumorigenesis and metastases of breast cancer. From 49 premenopausal women, samples were collected from benign or malignant tumors and the seemingly normal tissue adjacent to the tumor. The factors studied, with real-time polymerase chain reaction (PCR) and immunohistochemistry, were cyclooxygenase-1 and cyclooxygenase-2 (COX-1 and COX-2), syndecan-1 (S-1) and connective tissue growth factor (CTGF). COX-1 and S-1 mRNA levels were higher in the malignant tumors than in normal and benign tissues. The COX-2 mRNA level was lower in the malignant tumor than in the normal tissue, while CTGF mRNA did not differ between the groups. COX-1 immunostaining was higher in stroma from malignant tumors than in benign tissues, whereas COX-2 immunostaining was higher in the malignant tissue. Glandular S-1 immunostaining was lower in malignant tumors compared to benign and normal tissues, and the opposite was found in stroma. Conclusively, mRNA levels of COX-1 and COX-2 were oppositely regulated, with COX-1 being increased in the malignant tumor while COX-2 was decreased. S-1 protein localization switched from glandular to stromal cells in malignant tissues. Thus, these markers are, in premenopausal women, localized and regulated differently in normal/benign breast tissue as compared to the malignant tumor.

    Background Clinical trial results suggest that 5-alpha reductase inhibitors (5ARIs) for the treatment of benign prostatic hyperplasia (BPH) may increase the risk of gynecomastia and male breast cancer, but epidemiological studies have been limited. Patients and methods We conducted a cohort study with nested case–control analyses using the UK Clinical Practice Research Datalink. We identified men diagnosed with BPH who were free from Klinefelter syndrome, prostate, genital or urinary cancer, prostatectomy or orchiectomy, or evidence of gynecomastia or breast cancer. Patients entered the cohort at age ≥40 years and at least 3 years after the start of their electronic medical record. We classified exposure as 5ARIs (alone or in combination with alpha blockers [ABs]), AB only, or unexposed to 5ARIs and ABs. Cases were men who had a first-time diagnosis of gynecomastia or breast cancer. Incidence rates and incidence rate ratios (IRRs) with 95% confidence intervals (CIs) in the gynecomastia analysis and crude and adjusted odds ratios (ORs) with 95% CIs in both analyses were calculated. Results Compared to no exposure, gynecomastia risk was elevated for users of 5ARIs (alone or in combination with ABs) in both the cohort (IRR=3.55, 95% CI 3.05–4.14) and case–control analyses (OR=3.31, 95% CI 2.66–4.10), whereas the risk was null for users of AB only. The increased risk of gynecomastia with the use of 5ARIs persisted regardless of the number of prescriptions, exposure timing, and presence or absence of concomitant prescriptions for drugs known to be associated with gynecomastia. The risk was higher for dutasteride than for finasteride. 5ARI users did not have an increased risk of breast cancer compared to unexposed men (OR=1.52, 95% CI 0.61–3.80). Conclusion In men with BPH, 5ARIs significantly increased the risk of gynecomastia, but not breast cancer, compared to AB use and no exposure. PMID:28228662

    Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions

    Surgery is the treatment of choice for symptomatic tracheal obstruction due to benign or malignant thyroid disease. In case of inoperability, or when surgery is refused, few therapeutic alternatives are available. Interventional bronchoscopic procedures have only been reported anecdotally. The objective of this study is to evaluate the results of interventional bronchoscopic procedures in the treatment of severe tracheal obstruction due to thyroid disease. Retrospective cohort analysis. University hospital, tertiary referral center. Thirty consecutive patients referred for bronchoscopic treatment of benign (n = 17) or malignant (n = 13) thyroid-related upper airway obstruction due to tracheomalacia, extrinsic compression, and/or tracheal ingrowth. Indications for bronchoscopic treatment were medical or surgical inoperability, prevention or treatment of tracheomalacia, and refusal of surgery. There were no procedure-related complications. Rigid bronchoscopy with dilatation, stenting and/or Nd-YAG laser treatment, and clinical follow-up. Subjective improvement, pulmonary function tests, early and late complications, and survival. In the benign group, immediate (100% relief of dyspnea) and long-term (88% relief of dyspnea) results were excellent after airway stenting (21 stents used in 17 patients). There was one unrelated death 1 week after stenting in a 98-year-old patient. There were 6% and 30% short-term and long-term complications, respectively, that could be managed endoscopically. In the malignant group, Nd-YAG laser treatment (n = 3) and stenting (n = 13) yielded immediate and long-term success in 92% of patients. There were 15% short-term and 8% long-term complications. Median survival time was 540 days. Interventional bronchoscopic procedures including Nd-YAG laser treatment and stenting are valuable alternatives to surgery in inoperable thyroid-induced tracheal obstruction, or when surgery is refused.

    Previous studies have not showed consistent results for the level of expression of sodium/iodide symporter (NIS) in thyroid diseases, especially malignant tumor. We undertook this study to evaluate the distribution of NIS expression in malignant thyroid diseases and compare with that in benign thyoid disease. Total patients were 119 cases (Men 15, 48{+-}13 yrs). Total number of samples were 205 pieces. In malignant thyroid disease, there were 153 samples: 90 in papillary carcinoma, 4 in follicular carcinoma, 2 in medullary carcinoma and 57 in metastatic lymph node. In benign thyroid disease, there were 52 samples: 36 in goiter/cyst, 11 in thyroiditis and 5 in follicular adenoma. Using immunohistochemical methods, we probed 205 samples with monoclonal anti-NIS Ab. Grading of staining was scored as 0 (negative or absent), 1 (weakly positive), 2 (moderately positive) or 3 (strongly positive). Expression rate (ER) of NIS positivity in individual disease entity was expressed as percentage of total number divided by number in 2 plus 3 grade. ERs of malignant thyroid diseases were 63% in papillary carcinoma, 81% in metastatic lymph node, 71% in follicular carcinoma and 100% in medullary carcinoma. ERs of benign thyroid disease were 53% in goiter/cyst, 64% in thyroiditis and 40% in follicular adenoma. ER of benign thyroid deceases was higher than benign thyroid diseases (71% vs 54%). Grading of NIS expression in papillary carcinoma or goiter/cyst was heterogeneously distributed in considerable cases. Normal tissue also showed heterogeneous distribution or NIS expression, which was not correlated with that of primary lesion. In papillary thyroid carcinoma, distribution of NIS expression was heterogeneous and increased, and not different compared with that of benign thyroid disease.

    Background: Radiotherapy of benign diseases is controversial and rarely applied in Anglo-American countries, whereas in other parts of the world it is commonly practiced for several benign disorders. Similar to a European survey, a pattern of care study was conducted in Germany. Method: Using a mailed questionnaire, radiation equipment, treatment indication, number of patients, and treatment concepts were assessed in 1994, 1995, and 1996 in 134 of 152 German institutions (88%): 22 in East and 112 in West Germany; 30 in university hospitals and 104 in community hospitals. Average numbers of each institution and of all institutions were analyzed for frequencies and ratios between regions and among institutions. Radiation treatment concepts were analyzed. Results: A mean of 2 (range 1-7) megavoltage and 1.4 (range 0-4) orthovoltage units were available per institution; 32 institutions (24%) had no orthovoltage equipment. A mean of 20,082 patients were treated annually: 456 (2%) for inflammatory diseases (221 hidradenitis, 78 local infection, 23 parotitis; 134 not specified) 12,600 (63%) for degenerative diseases (2711 peritendinitis humeroscapularis, 1555 epicondylitis humeri; 1382 plantar/dorsal heel spur; 2434 degenerative osteoarthritis; 4518 not specified); 927 (5%) for hyperproliferative diseases (146 Dupuytren's contracture, 382 keloids; 155 Peyronie's disease; 244 not specified); 1210 (6%) for functional disorders (853 Graves' orbitopathy; 357 not specified); and 4889 (24%) for other disorders (e.g., 3680 heterotopic ossification prophylaxis). In univariate analysis, there were geographic (West vs. East Germany) differences in using radiation therapy (RT) for inflammatory and degenerative disorders, and institutional differences (university versus community hospitals) in using RT for hyperproliferative and functional disorders (p < 0.05). The prescribed dose concepts were mostly in the low dose range, <10 Gy but varied widely and inconsistently within

    BORIS, a paralog of the multifunctional CCCTC-binding factor (CTCF) gene is restricted to testis and normally not present in females. It is aberrantly activated in various human cancers including cancer breast. Using immunohistochemistry, western blot and/or RT-PCR, significantly higher levels of BORIS expression were reported in the neutrophils of cancer breast patients. We hypothesized that Flow Cytometry might be a better technique for objective quantitative evaluation of BORIS in neutrophils and we wanted to investigate if BORIS would discriminate between benign and malignant breast lesions. The study included 85 females; 52 breast cancer, 13 benign breast lesions and 20 age-matched healthy controls. BORIS expression in the neutrophils was detected by Flow Cytometry. High level of BORIS was detected in all malignant (64.4 ± 16.6%) and benign cases (67 ± 12.3), mean florescent intensity ratio (MFIR) of 7.2 ± 4.1 and 7 ± 3.5, median 5.8 and 6.6%; and staining index (SI) 8.3 ± 3.9 and 8.2 ± 3.4, median 7.6 and 7.9 respectively vs.13.4 ± 11.5% MFI 1.8 ± 0.7, median1.6 and SI 2.6 ± 0.69, median 2.5 for the control. BORIS level was comparable in the malignant and benign group (P = 0.934) and significantly higher than control (P = 0.0001). There was no correlation between neutrophil BORIS expression and ER/PR status, HER-2/neu expression or tumor stage or size. Increased BORIS expression in peripheral blood neutrophils is associated with both benign and malignant breast lesions; apparently, increased proliferation of breast tissue is the determining factor. This excludes BORIS as a tumor marker but it does not jeopardize its value as a potential therapeutic target. © 2016 International Clinical Cytometry Society. © 2016 International Clinical Cytometry Society.

    Full Text Available Objective: To assess and compare the risk factors in patients with benign gastric and duodenal ulcers and to correlate the prevalence of Helicobacter pylori (H. pylori infection in benign peptic ulcer disease. Methods: A total of 30 consecutive patients with peptic ulcer disease were included in this study after upper gastrointestinal endoscopy. Their clinical profile and endoscopic findings were noted. Antral biopsies were subjected to histopathological examination and urease test for detection of H. pylori. Results were correlated. The study was cleared by the Institute Research Council and the Ethics committee. Results: The male: female ratio was 11:4. Overall, H. pylori infection was prevalent in 93.3% of the patients. Patients who took spicy food had a significantly higher rate of H. pylori positivity (P=0.04. Smoking, alcohol intake and NSAIDs did not affect H. pylori status in patients. There was no significant association between the site of the ulcer and H. pylori infection. Conclusions: Based on our observations we conclude that prevalence of H. pylori infection is similar in duodenal and gastric ulcers and intake of spicy food is a significant risk factor.

    Distal pancreatectomy is the standard curative treatment for symptomatic benign, premalignant, and malignant disease of the pancreatic body and tail. The most obvious benefits of a laparoscopic approach to distal pancreatectomy include earlier recovery and shorter hospital stay. Spleen-preserving distal pancreatectomy should be attempted in case of benign disease. Spleen preservation can be achieved preferably by preserving the splenic vessels (Kimura technique), but also by resecting the splenic vessels and maintaining vascularity through the short gastric vessels and left gastroepiploic artery (Warshaw technique). Several studies have suggested a higher rate of spleen preservation with laparoscopy. The radical antegrade modular pancreatosplenectomy has become mainstay for treating pancreatic cancer and can be performed laparoscopically as well. Evidence on the feasibility and safety of laparoscopic distal pancreatectomy for cancer is scarce. Despite the obvious advantages of laparoscopic surgery, postoperative morbidity remains relatively high, mainly because of the high incidence of pancreatic fistula. For decades, surgeons have tried to prevent these fistulas but to date no strategy has been confirmed to be effective in 2 consecutive randomized studies. Pragmatic multicenter studies focusing on technical aspects of laparoscopic distal pancreatectomy are lacking and should be encouraged. PMID:26240565

    A deep understanding of thyroid pathophysiology is the basis for diagnosing and treating benign thyroid diseases with radioactive materials, known as radiopharmaceuticals, which are introduced into the body by injection or orally. After the radiotracer administration, the patient becomes the emitting source, and several devices have been studied to detect and capture these emissions (gamma or beta-negative) and transform them into photons, parametric images, numbers and molecular information. Thyroid scintigraphy is the only technique that allows the assessment of thyroid regional function and, therefore, the detection of areas of autonomously functioning thyroid nodules. Scintigraphy visualizes the distribution of active thyroid tissue and displays the differential accumulation of radionuclides in the investigated cells, thus providing a functional map. Moreover, this technique is a fundamental tool in the clinical and surgical management of thyroid diseases, including: single thyroid nodules with a suppressed thyroid-stimulating hormone level, for which fine-needle aspiration biopsy (FNAB) is used to identify hot nodules; multinodular goiters, especially larger ones, to identify cold or indeterminate areas requiring FNAB and hot areas that do not need cytologic evaluation, and to evaluate mediastinal extension; the diagnosis of ectopic thyroid tissue; subclinical hyperthyroidism to identify occult hyperfunctioning tissue; follicular lesions to identify a functioning cellular adenoma that could be benign, although such nodules are mostly cold on scintigraphy; to distinguish low-uptake from high-uptake thyrotoxicosis, and to determine eligibility for radioiodine therapy. © 2016 S.

    Objectives: To retrospectively investigate the added value of kinetic features measured by computer-aided diagnosis (CAD) for differentiating benign and malignant contralateral breast lesions detected by preoperative MRI in breast cancer patients. Methods: This study was approved by our institutional review board, and the requirement for informed consent was waived. Fifty-two breast MR images and their CAD kinetic features were obtained for 52 consecutive breast cancer patients with contralateral breast lesions detected by preoperative MRI and confirmed by excision (23 cancers and 29 benign lesions). Three experienced radiologists independently reviewed the MR images without CAD information and assessed probabilities of malignancy. Four weeks later, these probabilities were reanalyzed using stored CAD data. Diagnostic performances and detection rates of delayed washout components were compared between interpretations without and with CAD for each reader. Results: Use of MR CAD increased detection of washout component by 2.4- to 3.7-fold than visual assessment for enhancing contralateral lesions, which increased sensitivity (91% vs. 87% in reader 1; 96% vs. 74% in reader 2; 91% vs. 70% in reader 3) and decreased specificity, but statistical significance was only found for decreased specificity in one reader (52% vs. 28%, P = 0.039), and overall performance (areas under ROC curves 0.672 vs. 0.616 in reader 1; 0.624 vs. 0.603 in reader 2; 0.706 vs. 0.590 in reader 3) remained unimproved. Conclusion: Addition of MR CAD increased sensitivity and decreased specificity than radiologist's assessment alone for differentiating benign and malignant contralateral lesions in breast cancer patients and overall performance remained unimproved.

    Full Text Available OBJECTIVE To assess safety and feasibility of non-descent vaginal hysterectomy for benign gynaecological disease. METHODS A prospective study was conducted at the Department of Obstetrics and Gynaecology of P K Das Institute of Medical Sciences from January 2013 to December 2013. An effort was made to perform hysterectomies vaginally in women with benign or premalignant conditions in the absence of prolapse. A suspected adnexal pathology, endometriosis, immobility of uterus, uterus size more than 16 weeks was excluded from the study. Vaginal hysterectomy was done in usual manner. In bigger size uterus, morcellation techniques like bisection, debulking, coring, myomectomy, or combination of these were used to remove the uterus. Data regarding age, parity, uterine size, estimated blood loss, length of operation, intraoperative and postoperative complications and hospital stay were recorded. RESULTS A total of 100 cases were selected for non-descent vaginal hysterectomy. Among them, 97 cases successfully underwent nondescent vaginal hysterectomy. Majority of the patients (55% were in age group 40-45 yrs. Four patients were nulligravida and eight patients had previous LSCS. Uterine size was ≤ 12 weeks in 84 cases and > 12-16 weeks in 16 cases. Commonest indication was leiomyoma of uterus (43%. Mean duration of surgery was 70±20.5 minutes. Mean blood loss was 150±65 mL. Reasons for failure to perform NDVH was difficulty in opening pouch of Douglas in two cases because of adhesions and in one case there was difficulty in reaching the fundal myoma which prevented the uterine descent. Intra–operatively, one case had bladder injury (1% that had previous 2 LSCS. Postoperatively, complications were minimal which included postoperative fever (11%, UTI (8% and vaginal cuff infection was (4%. Mean hospital stay was 3.5 days. CONCLUSION Vaginal hysterectomy is safe, feasible in most of the women requiring hysterectomy for benign conditions with less

    Dose planning prior to radioiodine therapy of benign thyroidal disease is usually based on macrodosimetry. The paper shows that this assumption is acceptable. The common concepts for dose planning are given. The following target doses are nowadays widely accepted: 150 Gy for euthyroid goiter, 400 Gy for toxic adenoma, 150 Gy for disserminated autonomy, 200 Gy for hyperthyroid Grave's disease if posttherapeutic euthyroidism is intended, and 250 (to 300) Gy if the risk of recurrency is to be minimized ('ablative' concept). Finally, a surveyfis given concerning the precision in which the parameters relevant for the dose calcultion can be determined. For realistic favourable conditions, the dose can be determined with an accuracy of better than ±25%. (orig.) [de

    Radioiodine treatment is considered to be the treatment of choice in benign thyroid diseases because of its very low side effects. Real and hypothetic risks and side effects have to be differentiated. Both may occur early and late after the treatment. Radioiodinethyroiditis in small volumes at high doses is very rare. Exacerbation of a thyroid storm (0.34%) as well as local compressions accompanied with reactive edema of the thyroid are early real side effects of radioiodine treatment. Late real side effects are failure of treatment (7-30% of thyrotoxicosis) and induction of hypothyroidism (4-20% of functional autonomy and increasing frequency in Graves' diseases with time). Late hypothetic risks are somatic (1-9/10000 bis 1-9/100000) or genetic (1-9/100000). An early risk might be the misdiagnosis of an additional thyroid carcinoma. (orig.) [de

    Comparative preliminary analysis of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) data collected in the International Breast MR Consortium 6883 multicenter trial was performed to distinguish benign and malignant breast tumors. Prebiopsy DCE-MRI data from 45 patients with suspicious breast lesions were obtained. Semiquantitative mean signal-enhancement ratio ([Formula: see text]) was calculated for all lesions, and quantitative pharmacokinetic, parameters [Formula: see text], [Formula: see text], and [Formula: see text], were calculated for the subset with available [Formula: see text] maps ([Formula: see text]). Diagnostic performance was estimated for DCE-MRI parameters and compared to standard clinical MRI assessment. Quantitative and semiquantitative metrics discriminated benign and malignant lesions, with receiver operating characteristic area under the curve (AUC) values of 0.71, 0.70, and 0.82 for [Formula: see text], [Formula: see text], and [Formula: see text], respectively ([Formula: see text]). At equal 94% sensitivity, the specificity and positive predictive value of [Formula: see text] (53% and 63%, respectively) and K trans (42% and 58%) were higher than clinical MRI assessment (32% and 54%). A multivariable model combining [Formula: see text] and clinical MRI assessment had an AUC value of 0.87. Quantitative pharmacokinetic and semiquantitative analyses of DCE-MRI improves discrimination of benign and malignant breast tumors, with our findings suggesting higher diagnostic accuracy using [Formula: see text]. [Formula: see text] has potential to help reduce unnecessary biopsies resulting from routine breast imaging.

    To evaluate the diagnostic performance of three-dimensional (3D) image shear-wave elastography (SWE) for differentiating benign from malignant breast masses compared to two-dimensional (2D) SWE and B-mode ultrasound (US). This study consisted of 205 breast lesions from 199 patients who underwent B-mode US and SWE before biopsy from January 2014 to March 2016. Quantitative elasticity values (maximum and mean elasticity, Emax and Emean) obtained from 2D and 3D SWE (axial, sagittal, and coronal images) were reviewed retrospectively, in addition to the histopathological findings including immunohistochemistry profiles (luminal A, luminal B, human epidermal growth factor receptor 2 (HER2)-enriched, and triple-negative breast cancer) in cases of malignancy. Histopathological findings were regarded as the reference standard. The diagnostic performance of each data set was evaluated using the area under the receiver operating characteristic (ROC) curve (AUC) analysis to compare sensitivity and specificity. Among 205 lesions, 105 (51.22%) were malignant and 100 (48.78%) were benign. Compared to benign masses, malignant masses had higher values of Emax and Emean on both 2D and 3D SWE, the differences of which were statistically significant (pBreast Imaging-Reporting and Data System (BI-RADS) category 3 and category 4a lesions by adding each of the parameters for 2D and 3D SWE in B-mode US.

    Postoperative hypocalcaemia has been reported to be more common after total thyroidectomy (TT) for Graves' disease than after TT for benign atoxic multinodular goitre (MNG). The reasons for this potential association are not clear. In the present study, the frequency and risk factors of hypocalcaemia after TT for Graves' vs MNG were compared. Between January 1999 and October 2009, patients with first-time surgery for Graves' disease or MNG treated with a TT were included in the study. Postoperative hypocalcaemia was defined by symptoms, calcium levels and treatment with calcium and/or vitamin D analogues during postoperative hospital stay, at discharge, and at the 6-week and 6-month follow-ups. Outcomes were compared with Mann-Whitney, chi(2) and Fishers' exact test where appropriate and by multivariable logistic regression analysis. There were 128 patients with Graves' disease and 81 patients with MNG. Patients with Graves' disease were younger than patients with MNG (median age, 35 vs 51 years, p Graves' disease (p Graves' disease, there was no difference in the overall frequency of biochemical hypocalcaemia, low levels of PTH and/or treatment with calcium and vitamin D.

    The aim was to determine the efficacy, safety, and long-term clinical and functional results of coloanal anastomosis in patients with complicated benign and malignant rectal disease. Twenty-nine patients underwent coloanal or colopouch-anal anastomosis for either carcinoma of the rectum not technically amenable to conventional low anterior resection, severe radiation injury, large benign lower third tumors, or complications of previous operations. The mean age of the patients was 61 years and 82% were men. A diverting colostomy was constructed in 55% of the patients. The mean (+/- SEM) length of follow-up was 20 +/- 3 months. There was no operative mortality. Transient urinary retention, however, occurred in 40%, anastomotic stricture in 28%, and anastomotic leakage in 3.4%. Four patients (14%) could not have intestinal continuity restored and therefore were considered failures. The stool frequency for all remaining patients (N = 25) was 3 +/- 1 per day (mean +/- SEM) and did not vary with age, sex, or indication for operation. Complete continence was achieved by 84% of patients, but no patient was incapacitated by poor bowel function. In patients in whom a conventional colorectostomy is impractical or unwise, coloanal anastomosis is a safe and efficacious alternative operation that preserves anal continence.

    Full Text Available Photodynamic therapy (PDT uses a photosensitizer, light energy, and molecular oxygen to cause cell damage. Cells exposed to the photosensitizer are susceptible to destruction upon light absorption because excitation of the photosensitizing agents leads to the production of reactive oxygen species and, subsequently, direct cytotoxicity. Using the intrinsic cellular heme biosynthetic pathway, topical PDT selectively targets abnormal cells, while preserving normal surrounding tissues. This selective cytotoxic effect is the basis for the use of PDT in antitumor treatment. Clinically, PDT is a widely used therapeutic regimen for oncologic skin conditions such as actinic keratosis, squamous cell carcinoma in situ, and basal cell carcinoma. PDT has been shown, under certain circumstances, to stimulate the immune system and produce antibacterial, and/or regenerative effects while protecting cell viability. Thus, it may be useful for treating benign skin conditions. An increasing number of studies support the idea that PDT may be effective for treating acne vulgaris and several other inflammatory/infective skin diseases, including psoriasis, rosacea, viral warts, and aging-related changes. This review provides an overview of the clinical investigations of PDT and discusses each of the essential aspects of the sequence: its mechanism of action, common photosensitizers, light sources, and clinical applications in dermatology. Of the numerous clinical trials of PDT in dermatology, this review focuses on those studies that have reported remarkable therapeutic benefits following topical PDT for benign skin conditions such as acne vulgaris, viral warts, and photorejuvenation without causing severe side effects.

    This study aimed to evaluate concurrently detected thyroid pathologies in the patients who underwent surgery for primary hyperparathyroidism (PHPT). In this study, we retrospectively analyzed the files of the patients who underwent surgery for PHPT between 2012 and 2015. Pre- and post-operative laboratory examination results and preoperative radiological and nuclear medicine findings of the patients were retrospectively recorded. A total number of 41 patients with PHPT were divided into two groups as the Group 1 with PHPT and benign thyroid pathology (21 patients) and the Group 2 with PHPT and malignant thyroid pathology (20 patients). In Group 1, 18 and 3 of 21 patients were females and males, respectively. Group 2 included 15 male and 5 female patients. The mean age of the patients was found to be 55.6 and 53.9 years in Group 1 and Group 2, respectively. Both groups were matched for age and gender. In terms of thyroid pathology, 20 of 41 patients (48.7%) who underwent total thyroidectomy for PHPT were found to have thyroid papillary carcinoma while benign pathologic conditions were detected in 21 (51.3%) individuals. Cooccurrence of thyroid diseases and PHPT is common. Therefore, all the patients should preoperatively be evaluated for the presence of thyroid pathology to determine the technique of parathyroid surgery.

    One or more abnormal vertebrae detected on bone scintigraphy is a common finding in clinical practice, and it could pose a diagnostic dilemma especially in cancer patients, as either metastasis or benign disease may cause scintigraphic abnormality. The purpose of this study was to determine whether additional spine SPECT has a role in differentiating malignant from benign lesions in patients with back pain. We reviewed spine SPECT studies obtained over a three-year period in 108 patients. Among them, forty-five patients with abnormal SPECT and clinically followed records were evaluated (20 cancer patients were included). Uptake patterns were classified as follows: 1. Body: diffusely increased uptake, linear increased uptake of end plate, segmental increased uptake, and cold defect, 2 Posterior element; posterior to body (pedicle), posterior to intervertebral disc space (facet joint), and spinous process. Lesions were correlated with radiological findings and with final diagnosis. Sixty-nine bone lesions were detected on SPECT images, including 18 metastases, 28 degenerative diseases and 21 compression fractures. Cold defect (6) and segmental increased uptake (5) were dominant findings in metastasis: linear increased uptake (12), and facet joint uptake (15) were in degenerative change; and diffuse increased uptake (9), and linear increased uptake (9) were in compression fracture. Cold defect and segmental increased uptake of body were characteristic findings of metastasis, but care should be taken because compression fracture also shows segmental increased uptake in some cases. Degenerative disease was easily diagnosed because of the typical finding of linear increased uptake of end plate and facet joint. Therefore, additional bone SPECT after planar bone scan would be helpful for differentiating metastasis from benign condition in cancer patients

    To prospectively compare the diagnostic performances of two-dimensional (2D) and three-dimensional (3D) shear-wave elastography (SWE) for differentiating benign from malignant breast masses. B-mode ultrasound and SWE were performed for 134 consecutive women with 144 breast masses before biopsy. Quantitative elasticity values (maximum and mean elasticity in the stiffest portion of mass, Emax and Emean; lesion-to-fat elasticity ratio, Erat) were measured with both 2D and 3D SWE. The area under the receiver operating characteristic curve (AUC), sensitivity and specificity of B-mode, 2D, 3D SWE and combined data of B-mode and SWE were compared. Sixty-seven of the 144 breast masses (47 %) were malignant. Overall, higher elasticity values of 3D SWE than 2D SWE were noted for both benign and malignant masses. The AUC for 2D and 3D SWE were not significantly different: Emean, 0.938 vs 0.928; Emax, 0.939 vs 0.930; Erat, 0.907 vs 0.871. Either 2D or 3D SWE significantly improved the specificity of B-mode ultrasound from 29.9 % (23 of 77) up to 71.4 % (55 of 77) and 63.6 % (49 of 77) without a significant change in sensitivity. Two-dimensional and 3D SWE performed equally in distinguishing benign from malignant masses and both techniques improved the specificity of B-mode ultrasound.

    Proliferative benign breast conditions are associated with elevated risk of breast cancer, whereas nonproliferative conditions are not strongly associated with risk. Factors acting before onset of hyperplasia might be associated with both benign conditions and breast cancer, whereas those on the proliferative disease-to-cancer pathway would be associated only with cancer. Soy isoflavone exposure may influence breast cancer risk, but little is known of its association with benign conditions. We examined possible relationships between plasma genistein and daidzein concentrations and risk of breast disease in women, in a breast self-examination trial in Shanghai, China, diagnosed with breast cancer (n = 196) or a benign breast condition (n = 304), and 1,002 age-matched controls with no known breast disease. Benign conditions were classified as nonproliferative (n = 131) or proliferative with or without atypia (n = 173). Isoflavone concentrations were inversely associated with risk of nonproliferative and proliferative benign fibrocystic conditions, as well as with breast cancer, both with and without concomitant proliferative changes in ipsilateral noncancerous mammary epithelium (P(trend) 76.95 ng/mL) were less likely to have breast cancer (odds ratio, 0.26; 95% confidence interval, 0.13-0.50) or benign conditions (odds ratio, 0.40; 95% confidence interval, 0.23-0.70) compared with women in the lowest quartile (breast cancer with and without surrounding proliferative changes were not different, respectively, from observed risks for benign proliferative and nonproliferative conditions alone. Isoflavone exposure was inversely associated with fibrocystic breast conditions and breast cancer, and the results suggest that effects on cancer risk occur early in carcinogenesis.

    In a retrospective study of 400 dynamic MR examinations of the breast the signal/time ratio of 62 histopathologically correlated lesions (19 benign, 42 malignant) was evaluated. Points of evaluations were initial signal enhancement (1st and 2nd minute), post-initial signal apperance (2nd to 5th minute) and signal distribution (homogeneous, marginal). Based on these criteria, a point system was defined to help in the assessment of lesions in dynamic breast-MR imaging. The overall sensitivity of this method was 95.3%, the specificity to 89.5% and the accuracy to 93.5%. Pitfalls resulted in two cases of non-invasive carcinoma and in two patients with fibroadenoma.

    Cytological changes in terms of shape and size of nuclei are some of the common morphometric features to study breast cancer, which can be observed by careful screening of fine needle aspiration cytology (FNAC) images. This study attempts to categorize a collection of FNAC microscopic images into benign and malignant classes based on family of probability distribution using some morphometric features of cell nuclei. For this study, features namely area, perimeter, eccentricity, compactness, and circularity of cell nuclei were extracted from FNAC images of both benign and malignant samples using an image processing technique. All experiments were performed on a generated FNAC image database containing 564 malignant (cancerous) and 693 benign (noncancerous) cell level images. The five-set extracted features were reduced to three-set (area, perimeter, and circularity) based on the mean statistic. Finally, the data were fitted to the generalized Pearsonian system of frequency curve, so that the resulting distribution can be used as a statistical model. Pearsonian system is a family of distributions where kappa (κ) is the selection criteria computed as functions of the first four central moments. For the benign group, kappa (κ) corresponding to area, perimeter, and circularity was -0.00004, 0.0000, and 0.04155 and for malignant group it was 1016942, 0.01464, and -0.3213, respectively. Thus, the family of distribution related to these features for the benign and malignant group were different, and therefore, characterization of their probability curve will also be different.

    To develop a classification tree for the preoperative prediction of benign versus malignant disease in patients with small renal masses. This is a retrospective study including 395 consecutive patients who underwent surgical treatment for a renal mass classification tree to predict the risk of having a benign renal mass preoperatively was developed using recursive partitioning analysis for repeated measures outcomes. Age, sex, volume on preoperative imaging, tumor location (central/peripheral), degree of endophytic component (1%-100%), and tumor axis position were used as potential predictors to develop the model. Forty-five patients (11.4%) were found to have a benign mass postoperatively. A classification tree has been developed which can predict the risk of benign disease with an accuracy of 88.9% (95% CI: 85.3 to 91.8). The significant prognostic factors in the classification tree are tumor volume, degree of endophytic component and symptoms at diagnosis. As an example of its utilization, a renal mass with a volume of classification tree to predict the risk of benign disease in small renal masses has been developed to aid the clinician when deciding on treatment strategies for small renal masses.

    The goal of our study was to evaluate the diagnostic efficacy of diffusion-weighted imaging (DWI) in the differentiation of benign and malignant breast lesions. Between June 2012 and March 2013, 60 patients with 63 lesions (age range 29-70 years, mean age 48.6 years) were included in our study. All lesions, except complicated cysts and intra-mammary lymph nodes, were confirmed histopathologically. The patients were evaluated with a 1.5 Tesla MR scanner using dedicated bilateral breast coil. DWI images were obtained by echo planar imaging sequence and 'b' values were selected as 200, 600 and 1000 s/mm2. Apparent diffusion coefficient (ADC) values of both breast lesions and the normal fibroglandular tissue of the contralateral breast were calculated and statistically compared using Shapiro-Wilk test, Student's t-test, Mann-Whitney U test, chi-square test and the receiver operating curve. Of 63 lesions, 22 were malignant and 41 were benign. In malignant lesions, the mean ADC values were 1.40 ± 0.41 × 10 −3 mm 2 /s for b = 200, 1.05 ± 0.28 × 10 −3 mm 2 /s for b = 600 and 0.91 ± 0.20 × 10 −3 mm 2 /s for b = 1000 and in benign lesions, the mean ADC values were 2.13 ± 0.85 × 10 −3 mm 2 /s for b = 200, 1.64 ± 0.47 × 10 −3 mm 2 /s for b = 600 and 1.40 ± 0.43 × 10 −3 mm 2 /s for b = 1000. The success of ADC values in differentiation of benign and malignant lesions was statistically significant (P = 0.0001). The threshold values were determined to be 1.50 × 10 −3 mm 2 /s for b = 200, 1.22 × 10 −3 mm 2 /s for b = 600 and 0.98 × 10 −3 mm 2 /s for b = 1000 (P < 0.05). DWI can be an effective radiological method in the differentiation of benign and malignant breast lesions.

    In an effort to overcome the limitations of single-port laparoscopic cholecystectomy (LC) while preserving the cosmetic benefits of reduced ports cholecystectomy, we have developed a 2-port LC that allows for the full, unrestricted use of 4 laparoscopic instruments. We retrospectively analyzed data of patients who had undergone either 4-port LC or 2-port LC for benign gallbladder diseases between March 2007 and March 2013. Two incisions of 2-port LC were composed of an umbilical incision as the manner of single-port laparoscopic surgery and a 5-mm epigastric incision. These two incisions were utilized for comfortable bimanual manipulation under the liver-elevated vision provided by a liver retractor. During the study period, 766 patients underwent LC; 263 (34.3%) started with 4-port LC, and 503 (65.7%) started with 2-port LC. Of patients started with 2-port LC, 486 patients (96.6%) was ended up with 2-port without open conversion or addition of port(s). The two groups had similar operative time, open conversion rate, incidence of complications, analgesic requirement, and length of postoperative hospital stay. Multivariate analyses revealed that the independent factors related to prolonged operative time (≥ 90 th percentile) in 2-port LC were the presence of cholecystitis (odds ratio [OR] 2.412, 95% CI 1.246-4.668, p = 0.009) and admission through the emergency department (OR 2.132, 95% CI 1.135-4.004, p = 0.019). This study suggests that 2-port LC for benign gallbladder diseases is as safe and feasible as 4-port LC when it is performed by surgeons trained in conventional laparoscopic techniques.

  13. Application of SPECT/CT imaging in the diagnosis of benign diseases

    2014-01-01

    The application of recently introduced hybrid nuclear medicine methods gains importance in a variety of clinical fields, mainly because of the unique combination between functional and anatomical data provided by those methods and their capability for a precise localization of pathological processes. Single photon emission computed tomography, combined with computed tomography (SPECT/CT) is one of those methods. Its role in nuclear cardiology is important, because it provides quick attenuation correction and calculates the calcium score. In nuclear endocrinology SPECT/CT participates in thyroid and parathyroid examinations, especially in cases, where there is a need for localization of ectopic parathyroid or thyroid tissue. In nuclear pulmonology, one of the best ways to attribute certain changes seen on the SPECT, to the zone of interest on the CT, is to study the fused images obtained from the SPECT/ CT scanner. In cases of suspected infection and inflammation, fused images are indispensable for accurate localization of the involved tissue (structure) and for discrimination between normal/abnormal uptake. Careful reading of the CT component (even low-dose) is related (in 10% of cases) to clinically important incidental findings: effusions, tumors, metastases or lymph node pathology. SPECT/CT increases the specificity of the examinations and improves significantly the localization of pathological processes. It provides additional information, shortens the diagnostic algorithm and influences the extent of surgical procedures. In many hybrid examinations the preferred CT component is a low-dose one, without considerable radiation exposure. The opportunity to combine nuclear medicine techniques and contrast CT images, aiming at better diagnosis needs further development. SPECT/CT provides important additional information and more accurate diagnostics in patients with benign diseases. (authors) Key words: SPECT/CT. BENIGN DISEASES

    Full Text Available Abstract Background Colorectal cancer (CRC is often diagnosed at a late stage with concomitant poor prognosis. The hypersensitive analytical technique of proteomics can detect molecular changes before the tumor is palpable. The surface-enhanced laser desorption/ionization-time of flight-mass spectra (SELDI-TOF-MS is a newly-developed technique of evaluating protein separation in recent years. The protein chips have established the expression of tumor protein in the serum specimens and become the newly discovered markers for tumor diagnosis. The objective of this study was to find new markers of the diagnosis among groups of CRC, colorectal benign diseases (CBD and healthy controls. The assay of SELDI-TOF-MS with analytical technique of protein-chip bioinformatics was used to detect the expression of protein mass peaks in the sera of patients or controls. One hundred serum samples, including 52 cases of colorectal cancer, 27 cases of colorectal benign disease, and 21 cases of healthy controls, were examined by SELDI-TOF-MS with WCX2 protein-chips. Results The diagnostic models (I, II and III were setup by analyzed the data and sieved markers using Ciphergen - Protein-Chip-Software 5.1. These models were combined with 3 protein mass peaks to discriminate CRC, CBD, and healthy controls. The accuracy, the sensitivity and the particularity of cross verification of these models are all highly over 80%. Conclusions The SELDI-TOF-MS is a useful tool to help diagnose colorectal cancer, especially during the early stage. However, identification of the significantly differentiated proteins needs further study.

    Purpose: To determine the prevalence of breast arterial calcifications (BAC) detected on mammography and search for conditions that may influence their existence. Materials and methods: The mammograms of 6156 consecutive patients were reevaluated for the presence of BAC. Four hundred eighty-five women having BAC were enrolled in the patient group. Additionally, randomly selected 500 women, without BAC constituted the control group. Hospital records of the participants were reviewed for parity, menopausal status, oral contraceptive agent (OCA) usage, hormone replacement therapy (HRT) usage, presence of diabetes, hypertension, hyperlipidemia, albuminuria and history of myocardial infarction (MI). Results: Prevalence of BAC was 7.9% on mammograms. Ninety-four women were aged between 40 and 49 years, 165 were aged between 50 and 59 years and 226 were over 60 years among BAC positive 485 women. A significant relationship was found for the frequency of BAC versus age and HRT usage in all age groups (p 0.05). Conclusion: Most benign findings like BAC are not routinely reported during mammographic evaluation. Our study showed that, presence of BAC on mammography was strongly related to advancing age. However, these findings may signify a systemic risk and can be used as precautious indicators for undocumented systemic diseases, especially in premenopausal women

    The purposes of this study were to compare the tumor appearance of invasive breast cancer on direct-conversion molecular breast imaging using a standardized lexicon and to determine how often direct-conversion molecular breast imaging identifies all known invasive tumor foci in the breast, and whether this differs for invasive ductal versus lobular histologic profiles. Patients with prior invasive breast cancer and concurrent direct-conversion molecular breast imaging examinations were retrospectively reviewed. Blinded review of direct-conversion molecular breast imaging examinations was performed by one of two radiologists, according to a validated lexicon. Direct-conversion molecular breast imaging findings were matched with lesions described on the pathology report to exclude benign reasons for direct-conversion molecular breast imaging findings and to document direct-conversion molecular breast imaging-occult tumor foci. Associations between direct-conversion molecular breast imaging findings and tumor histologic profiles were examined using chi-square tests. In 286 patients, 390 invasive tumor foci were present in 294 breasts. A corresponding direct-conversion molecular breast imaging finding was present for 341 of 390 (87%) tumor foci described on the pathology report. Invasive ductal carcinoma (IDC) tumor foci were more likely to be a mass (40% IDC vs 15% invasive lobular carcinoma [ILC]; p < 0.001) and to have marked intensity than were ILC foci (63% IDC vs 32% ILC; p < 0.001). Direct-conversion molecular breast imaging correctly revealed all pathology-proven foci of invasive disease in 79.8% of cases and was more likely to do so for IDC than for ILC (86.1% vs 56.7%; p < 0.0001). Overall, direct-conversion molecular breast imaging showed all known invasive foci in 249 of 286 (87%) patients. Direct-conversion molecular breast imaging features of invasive cancer, including lesion type and intensity, differ by histologic subtype. Direct-conversion molecular

    Objective: To investigate the value of functional MRI in the diagnosis and differential diagnosis of breast diseases. Methods: Sixty-five patients with 68 lesions were enrolled in this study. Conventional T 1 WI and T 2 WI scan, dynamic contrast enhanced MRI, diffusion weighted imaging and 1 H single voxel MR spectroscopy were performed consequently. All lesions were verified by pathology, including 4 cases of breast adenosis, 22 fibroadenomas, 2 chronic inflammations, 3 cysts, 33 infitrating ductal carcinomas, 1 intraductal carcinoma and 3 cystosarcoma phyllodes tumors. Morphological features, maximum enhancement ratio, time-intensity curve, apparent diffusion coefficient and Choline peak were analyzed. Results: The detection rates of T 1 WI and T 2 WI were 14.7% (n=10) and 51.5% (n=35). The sensitivity, specificity, accuracy of dynamic contrast enhanced MRI for the malignant tumor were 94. 6%, 71.4% and 76.5% respectively. Retrospective study showed that diffusion weighted imaging, with the b value from 800 s/mm 2 to 1000 s/mm 2 , could be used to differentiate various types of breast lesions. 1 H signal voxel spectroscopy had a sensitivity of 51.4%, specificity of 82.6%, and accuracy of 67.6% for the malignent. The sensitivity, specificity and accuracy could reach 97.3%, 90.0% and 92.6% respectively by combining conventional scan, dynamic contrast enhanced MRI and MR spectroscopy. Conclusion: Functional MRI, with high sensitivity, specificity and accuracy, can be used widely in the diagnosis of malignant breast lesions. (authors)

    This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE), endorsed by the European Society for Radiotherapy and Oncology (ESTRO), the European Society of Digestive Endoscopy (ESDO), and the European Society for Clinical Nutrition and Metabolism (ESPEN). The Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system was adopted to define the strength of recommendations and the quality of evidence. Main recommendations for malignant disease 1 ESGE recommends placement of partially or fully covered self-expandable metal stents (SEMSs) for palliative treatment of malignant dysphagia over laser therapy, photodynamic therapy, and esophageal bypass (strong recommendation, high quality evidence). 2 For patients with longer life expectancy, ESGE recommends brachytherapy as a valid alternative or in addition to stenting in esophageal cancer patients with malignant dysphagia. Brachytherapy may provide a survival advantage and possibly a better quality of life compared to SEMS placement alone. (Strong recommendation, high quality evidence.) 3 ESGE recommends esophageal SEMS placement as the preferred treatment for sealing malignant tracheoesophageal or bronchoesophageal fistula (strong recommendation, low quality evidence). 4 ESGE does not recommend the use of concurrent external radiotherapy and esophageal stent treatment. SEMS placement is also not recommended as a bridge to surgery or prior to preoperative chemoradiotherapy. It is associated with a high incidence of adverse events and alternative satisfactory options such as placement of a feeding tube are available. (Strong recommendation, low quality evidence.) Main recommendations for benign disease 1 ESGE recommends against the use of self-expandable stents (SEMSs) as first-line therapy for the management of benign esophageal strictures because of the potential for adverse events, the availability of alternative therapies, and costs (strong

    Genes and proteins are known to have differences in their sensitivity to alterations. Despite numerous sequencing studies, proportions of harmful and harmless substitutions are not known for proteins and groups of proteins. To address this question, we predicted the outcome for all possible single amino acid substitutions (AASs) in nine representative protein groups by using the PON-P2 method. The effects on 996 proteins were studied and vast differences were noticed. Proteins in the cancer group harbor the largest proportion of harmful variants (42.1%), whereas the non-disease group of proteins not known to have a disease association and not involved in the housekeeping functions had the lowest number of harmful variants (4.2%). Differences in the proportions of the harmful and benign variants are wide within each group, but they still show clear differences between the groups. Frequently appearing protein domains show a wide spectrum of variant frequencies, whereas no major protein structural class-specific differences were noticed. AAS types in the original and variant residues showed distinctive patterns, which are shared by all the protein groups. The observations are relevant for understanding genetic bases of diseases, variation interpretation, and for the development of methods for that purpose. © 2017 Wiley Periodicals, Inc.

    Full Text Available A despeito do caráter benigno da endometriose, estima-se que 1% dos casos esteja relacionado com câncer, especialmente quando ambas as condições ocorrem nos ovários. Lesões extra-ovarianas encontradas no septo retovaginal, cólon, bexiga, vagina e peritônio da região pélvica também já foram associadas com neoplasias malignas. Várias características do tecido endometrial ectópico o aproximam do fenótipo neoplásico, e a própria endometriose possui comportamento tipicamente neoplásico com capacidade de invasão do estroma adjacente e associação com lesões à distância. Esta revisão atualiza conhecimentos diagnósticos, clínicos e terapêuticos dos implantes intestinais de tecido endometriótico, bem como sua relação com processos neoplásicos para melhor compreensão de seu caráter benigno ou de seu eventual potencial para malignidade.Endometriosis is generally assumed to be a benign disease, but it is estimated that 1% of cases are associated with cancer, especially when both conditions are present in the ovary. Extra-ovarian lesions in the rectovaginal septum, colon, bladder, vagina and peritoneum were already associated with malign neoplasia. Several characteristics of endometrial tissue are very similar to the neoplasia phenotype. Endometriosis itself typically behaves as a neoplasia process, spreading over adjacent stroma and being associated with distant lesions. This is an update on the diagnostic, clinical, and therapeutic knowledge of, management of bowel implants of endometrial tissue, as well as the relation with neoplastic processes to better understand its benign nature or eventual potential for malignancy.

    Objective: To study the clinical significance of perioperative changes of serum IL-10 level in patients with benign and malignant pulmonary diseases. Methods: Serum IL-10 levels in patients with benign (n=17) and malignant (n=25) pulmonary diseases were measured before and 1, 3, 7, 14 days after operation with RIA. Values in 82 controls were also taken. Results: The preoperative levels of serum IL-10 in patients with lung cancer were significantly higher than those in other groups (p 0.05); The levels of serum IL-10 in 36.4% of all the patients with lung cancer on day 14 were higher than the upper limit of the normal value. In patients with benign lung diseases, perioperative changes were slight and non-significant. Conclusion: Serum IL-10 level is a reliable parameter for distinguishing benign lung disease from malignant ones. Defining preoperative and postoperative changes of serum IL-10 levels might be of prognostic value in patients with lung cancer

    The clinical usefulness of mammography in postmenopausal women was evaluated by conducting a ''vertical'' analysis using indexes of sensitivity and specificity, and a separate ''horizontal'' analysis assessing the relationship between the mammographic test result and the occurrence of specific clinical management decisions. The patients included 105 women with breast cancer, 104 women with fibrocystic breast disease, and 103 women with clinically benign breasts. The study confirmed the generally accepted high values reported for the sensitivity and for the specificity of mammography as a test for breast cancer, while also helping to reconcile the widely varying indexes of test efficacy reported in some studies. The authors also observed that physicians' management decisions vary according to the mammographic interpretation, and include such distinctive clinical strategies as watchful expectancy (observe and follow), repeated mammograms, or breast biopsy. Future studies will need to determine reasons for specific management decisions, especially when they appear to contradict authoritative recommendations.

    In 1972, Beck introduced an inventory (BDI) for rapid screening of depression. The associations between the BDI and the risk of breast cancer (BC) are rarely considered together in prospective studies. In an extension of the Kuopio Breast Cancer Study, 115 women with breast cancer symptoms were semi-structurally interviewed in-depth as well as asked to complete standardised questionnaires (Forsen, Spielberger, MADRS), and all study variables were obtained before any diagnostic procedures were carried out. BDI was used to evaluate the depression of the study participants. The clinical examinations and biopsies showed BC in 34 patients, benign breast disease (BBD) in 53 patients, and 28 individuals were shown to be healthy (HSS). There was a trend for the women with HSS to have less sadness (BDI mean score, 0.27) than those of the BC (BDI mean score, 0.56) and BBD groups (BDI mean score, 0.49). The HSS group tended to be less pessimistic (BDI mean score, 0.15) than the patients in the BC group (BDI mean score, 0.44) and in the BBD group (BDI mean score, 0.42). The HSS group also had less self-accusation (BDI mean score, 0.19) than the patients in the BC group (BDI mean score, 0.50) and the patients in the BBD group (BDI mean score, 0.62). The HSS group also reported less work inhibition and weight loss than the patients in the BC group and in the BBD group. The mean sum of the scores of BDI variables was significantly lower in the HSS group (BDI mean score, 7.1) than in the BC (BDI mean score, 8.4) or BBD groups (BDI mean score, 8.8). The results of this study do not support a specific link between BDI and breast cancer risk. However, the patients with BC and BBD tended to have an increased risk for depressive symptoms.

    Mammography of male breast account for less than 1% of mammographic examinations in most breast services. Due to the low incidence of breast cancer in men the significant majority of mammographic diagnosis reveals benign diseases, mostly gynecomastia. Therefore it is most important to identify features of benign conditions, such as gynecomastia, in order to reduce the number of unnecessary surgical biopsies performed in these patients, for the same reason suspicious lesions must be recognized as well. Indications for mammography in men include evaluation of palpable mass, recent onset of breast nipple-areolar skin changes or papillary discharge, and previous history of cancer. (author)

    In order to study clinical significance of serum prostate-specific antigen (PSA), free prostate specific antigen (PSA), f/tPSA and six sex hormones in prostate diseases, the serum levels of PSA, fPSA, f/tPSA, T, P, E 2 , PRL, LH and FSH in 72 cases of hyperplasia of prostate patients and 40 patients with prostate cancer were determined by RIA. The results showed that the serum levels of T, E 2 , PRL, LH, FSH in the BPH Group were significantly lower than those of in Pca group, the serum level of P in Pca group were significantly lower than those in BPH group; the levels of fPSA and f/tPSA ratio in BPH Group were significantly higher than those in Pca group. The results suggest that benign and malignant prostate disease (BPH and Pca) was related with the hormone imbalance. The serum total PSA and fPSA can be regarded as important indicators in the diagnosis of BPH and Pea. The combined determination of PSA, fPSA and f/tPSA may improve the diagnostic accuracy of Pca.

    Full text: For the evaluation of bone metastases in patients (pts) with cancer, 99mTcMDP bone scintigraphy is an important tool, but some limitations exist. One of these is the differential diagnosis of malignant and degenerative benign bone disease. The aim of this study was to differentiate them using 99mTcCitrate and 99mTcMDP scintigraphy. Methods: 39 pts (92 lesions) with known malignant or degenerative benign bone disease were studied. 23 pts had malignant bone disease (48 lesions, group 1), the other 16 pts had degenerative benign bone disease (44 lesions, group2), for which the results of 99mTcMDP scintigraphy were positive. In both groups, 99mTcCitrate scintigraphy was performed within a time interval of 2-7 days after 99mTcMDP scintigraphy (555∼740MBq. static, 3hr, planar or SPECT i m a g e s w h e n r e q u i r e d ) . The 99mTccitrate/99mTcMDP lesion-to-background radioisotope uptake ratio (RUR) was calculated for each lesion. Conventional techniques (histopathology, X-ray, CT, MRI and clinical follow up) were considered to be proof of the presence of bone metastases and degenerative benign bone disease. Results: Uptake of 99mTcMDP in the two groups is the same (1.96±0.25 vs. 1.87±0.21; t=1.178, P>0.20), while in 99mTcCitrate image, malignant lesions demonstrated a higher uptake of lesion activity than that of benign degenerative lesions (1.47±0.42 vs. 1.09±0.38; t=2.887, P<0.01). The mean 99mTccitrate/99mTcMDP RUR in the malignant group was significantly higher than the mean in the benign group (0.78±0.21 vs. 0.54±0.19; t=3.646, P<0.001). Conclusions: The preliminary results of the study confirm the usefulness and feasibility of 99mTcCitrate scintigraphy for differentiating malignant from benign degenerative lesions seen as areas of increased activity on 99mTcMDP bone scintigraphy.

    To compare the diagnostic value of visual and semi-quantitative analysis of technetium-99m-poly-ethylene glycol, 4-arginine-glycine-aspartic acid ((99m)Tc-3PRGD2) scintimammography (SMG) for better differentiation of benign from malignant breast masses, and also investigate the incremental role of semi-quantitative index of SMG. A total of 72 patients with breast lesions were included in the study. Technetium-99m-3PRGD2 SMG was performed with single photon emission computed tomography (SPET) at 60 min after intravenous injection of 749 ± 86MBq of the radiotracer. Images were evaluated by visual interpretation and semi-quantitative indices of tumor to non-tumor (T/N) ratios, which were compared with pathology results. Receiver operating characteristics (ROC) curve analyses were performed to determine the optimal visual grade, to calculate cut-off values of semi-quantitative indices, and to compare visual and semi-quantitative diagnostic values. Among the 72 patients, 89 lesions were confirmed by histopathology after fine needle aspiration biopsy or surgery, 48 malignant and 41 benign lesions. The mean T/N ratio of (99m)Tc-3PRGD2 SMG in malignant lesions was significantly higher than that in benign lesions (Pvalue for the detection of primary breast cancer, the sensitivity, specificity and accuracy were 81.3%, 70.7%, and 76.4%, respectively. When a T/N ratio of 2.01 was used as cut-off value, the sensitivity, specificity and accuracy were 79.2%, 75.6%, and 77.5%, respectively. According to ROC analysis, the area under the curve for semi-quantitative analysis was higher than that for visual analysis, but the statistical difference was not significant (P=0.372). Compared with visual analysis or semi-quantitative analysis alone, the sensitivity, specificity and accuracy of visual analysis combined with semi-quantitative analysis in diagnosing primary breast cancer were higher, being: 87.5%, 82.9%, and 85.4%, respectively. The area under the curve was 0.891. Results of

    This thesis provides the fundamental characterization and differentiation of breast tissues using in vivo and ex vivo MR techniques in the hope that these techniques and experimental findings will be used on a larger scale and in a predictive manner in order to improve the specificity of diagnosis and treatment of breast cancer. In this dissertation, clinical studies were performed using proton magnetic resonance imaging and phosphorus magnetic resonance spectro-scopy ( 31 P MRS) to characterize and differentiate malignant breast tumors, benign breast tumors and normal breast tissues in vivo. These studies were carried out following the methodical characterization of chemical extracts of malignant breast tumor, benign breast tumor and normal breast parenchymal surgical tissue specimens using high resolution 31 P MRS. Alterations in breast tissue metabolism, as a result of pathological processes, were postulated to be responsible for measurable differences between malignant breast tumors, benign breast tumors and normal breast tissues using magnetic resonance techniques.

    Full Text Available Diabetic mastopathy is an uncommon, benign disease of the breast that can occur in women with diabetes and clinically mimic breast cancer. We describe a patient with long-standing type 1 diabetes who presented with a palpable breast mass with negative imaging findings on mammography, ultrasonography, and breast MRI. Surgical biopsy and histopathology confirmed diabetic mastopathy. We use this case to highlight the recognition, radiographic features, pathology, and management of this benign breast condition and emphasize that, in diabetic patients, the differential diagnosis of a new breast mass should include diabetic mastopathy.

    The purpose of this study is to evaluate the accuracy of differentiation between benign and malignant clustered microcalcifications without mass on mammogram. Fourty six mammograms of 44 patients showing clustered microcalcifications without mass were interpreted blindly by five independent observers majoring in breast imaging from different institutions. Twenty two were malignant (10 infiltrating ductal carcinomas, 12 intraductal carcinomas) and 24 were benign (all fibrocystic disease). The observers judge benignancy or malignancy of microcalcifications. The authors assess the accuracy of differential diagnosis of clustered microcalcifications. Of 24 cases proved benign microcalcifications, five radiologists correctly interpreted 20 on average as benign and of malignant 22 cases, 16 on average were correctly interpreted as malignant. The diagnostic accuracy of malignant microcalcifications was 71.8% on average(63.6%{approx}81.8%) and the diagnostic accuracy for benign microcalcifications was 83% on average(71%{approx}92%). It was 9 among total 46 cases that were misinterpreted by more than three radiologists. Among these 9 cases, malignant microcalcifications that had been misinterpreted as benign were seven, benign microcalcifications misinterpreted as malignant were two. The diagnostic accuracy of clustered malignant microcalcifications(71.8%) without mass on mammogram was lower than that of benign microcalcifications(83.3%). So, in case of suspected malignant microcalcification on mammogram, it is preferable that along with magnification view, histopathologic confirmation by core biopsy must be obtained.

Results: There were significant excess risks for all circulatory disease, with an excess relative risk Gy{sup -1} of 0.082 (95% CI 0.031-0.140), and ischemic heart disease, with an excess relative risk Gy{sup -1} of 0.102 (95% CI 0.039-0.174) (both p = 0.01), and indications of excess risk for stroke. There were no statistically significant (p > 0.2) differences between risks by endpoint, and few indications of curvature in the dose-response. There were significant (p < 0.001) modifications of relative risk by time since exposure, the magnitude of which did not vary between endpoints (p > 0.2). Risk modifications were similar if analysis was restricted to patients receiving radiation, although the relative risks were slightly larger and the risk of stroke failed to be significant. The slopes of the dose-response were generally consistent with those observed in the Japanese atomic bomb survivors and in occupationally and medically exposed groups. Conclusions: There were excess risks for a variety of circulatory diseases in this dataset, with significant modification of risk by time since exposure. The consistency of the dose-response slopes with those observed in radiotherapeutically treated groups at much higher dose, as well as in lower dose-exposed cohorts such as the Japanese atomic bomb survivors and nuclear workers, implies that there may be little sparing effect of fractionation of dose or low-dose-rate exposure.

    In radioiodine therapy of benign thyroid disease, a reduction of radioiodine uptake is known for consecutive administrations of 131I, which needs to be considered in therapy planning. Aim: Analysis of uptake reduction with regard on the time interval between radioiodine administration and the delivered dose to the thyroid tissue. Patients, methods: 200 patients were enrolled in the study and distributed into two groups (matched for diagnoses), each containing 32 patients with Graves' disease (target dose 250 Gy), 24 with focal (400 Gy), 44 with disseminated thyroid autonomy (150 Gy). In one group, a second fraction of radioiodine was given after 48 h (2d) due to an unexpected low radioiodine uptake or effective half-life, whereas in the other group the second fraction was given after 96 h (4d). Results: There was no significant difference between delivered doses due to the first fraction after four days: 2d: 86 ± 48 Gy (extrapolated) vs. 4d: 87 ± 41 Gy, p > 0.05. In 2d, delivered dose at time of second administration was significantly lower (51 μ 29 Gy) than in 4d (p < 0.01). The radioiodine uptake of the second fraction relative to the initial uptake was significantly lower in the 4d (4d: 63 ± 25% vs. 2d: 82 ± 24%, p < 0.01). In addition, a correlation between uptake reduction and delivered dose and an influence of the time interval between radioiodine administrations could be shown. Conclusions: Relative uptake of subsequent radioiodine fractions decreases with time after first administration and with increasing delivered dose to the thyroid. If a second fraction of 131I is given at an earlier time, the same therapeutic effect can be reached using lower amounts of activity, minimising radiation exposure and increasing efficiency of radioiodine therapy.

    Our aim was to ascertain the incidence of, reasons for, and risk factors associated with hospital readmission after an operation for benign distal esophageal disease. Using the American College of Surgeons National Surgical Quality Improvement Program database (2012-2014), patients with a primary diagnosis of gastroesophageal reflux disease, paraesophageal hiatal hernia, or achalasia who underwent fundoplication, paraesophageal hernia repair, or Heller myotomy were identified. The primary outcome was hospital readmission. Multivariable logistic regression analysis was used to identify risk factors associated with hospital readmission. Of the 14,478 patients included in this study, 801 (5.5%) were readmitted at a median of 11 days (interquartile range 6-17) postprocedure. Intolerance of oral intake (21.8%), respiratory complications (11.6%), abdominal pain (6.0%), and venous thromboembolic events (4.7%) were some of the most common reasons for readmission. Open operative approach (odds ratio 1.34, 95% confidence interval 1.05-1.71), chronic steroid use (odds ratio 1.48, 95% confidence interval 1.10-2.00), emergency admission (odds ratio 1.50, 95% confidence interval 1.01-2.21), and predischarge complication (odds ratio 1.91, 95% confidence interval 1.42-2.59) were associated most strongly with hospital readmission. Implementing standardized perioperative strategies, such as nutritional counseling, early ambulation, intensive pulmonary toilet, and deep vein thrombosis prophylaxis, may help decrease the number of preventable readmissions and enhance the overall quality of care in this patient population.

    To evaluate diagnostic performances of CESM for breast diseases with comparison to breast MRI in China. Sixty-eight patients with 77 breast lesions underwent MR and CESM. Two radiologists interpreted either MRI or CESM images, separately and independently. BI-RADS 1-3 and BI-RADS 4-5 were classified into the suspicious benign and suspicious malignant groups. Diagnostic accuracy parameters were calculated. Receiver operating characteristic (ROC) curves were constructed for the two modalities. The agreement and correlation between maximum lesion diameter based on CESM and MRI, or CESM and pathology were analyzed. Diagnostic accuracy parameters for CESM were sensitivity 95.8 %, specificity 65.5 %, PPV 82.1 %, NPV 90.5 % and accuracy 84.4 %. The diagnostic accuracy parameters for breast MRI were sensitivity 93.8 %, specificity 82.8 %, PPV 88.2 %, NPV 92.3 %and accuracy 89.6 %. Area under the curve (AUC) of ROC was 0.96 for breast MRI and 0.88 for CESM. The Bland-Altman plots showed a mean difference of 0.7 mm with 95 % limits of agreement of 11.4 mm in tumor diameter measured using CESM and breast MRI. The differences of size measurement between CESM and breast MRI were significant, whereas no difference was observed between CESM and pathology as well as between breast MRI and pathology. The better correlation with pathological results was found in CESM than breast MRI. Our study demonstrates that CESM possesses better diagnostic performances than breast MRI in terms of diagnostic sensitivity and lesion size assessment. And CESM is a good alternative method of screening breast cancer in high-risk people.

    Objective: To find the effective quantitative parameters for the differentiation of the breast lesions using the post-processing of time-signal curve of 3D dynamic-enhanced MRI. Methods: Thirty patients with 35 lesions underwent 3D dynamic-enhanced MRI and the time-signal curve was deduced. The four quantitative parameters including SImax, PH, Slope and Slope R were analyzed in benign and malignant lesions of the breast. Independent samples t test and rank sum test were used for the statistics. Results: Seyenteen benign lesions and 18 malignant lesions were included in this study. The SImax (M) of benign and malignant lesions were 375.2 and 158.1, the 95% confidence intervals of SImax were 278.2- 506. 0 and 160.5--374. 8. The PH (M) of benign and malignant lesions were 114.4 and 87. 8, the 95% confidence intervals of PH were 73.7-196.5 and 71.3-162. 9. The Slope (M) of benign and malignant lesions were 22.3 x 10 -3 and 44.0 x 10 -3 , the 95% confidence intervals of Slope were 13.7 x 10 -3 - 41.1 x 10 -3 and 46.1 x 10 -3 -81.8 x 10 -3 . The Slopea (M) of benign and malignant lesions were 2.6 and 11.4, the 95% confidence intervals of Slopea were 1.9-3.4 and 9.8-14.5. There were no significant differences on SImax and PH between benign and malignant lesions (P>0.05). The significant differences existed on Slope (P<0.01) and Slopea (P <0.01) between benign and malignant lesions of the breast. Conclusion: Slopea is a very effective parameter in the differential diagnosis of breast lesions. (authors)

    Diffuse skin thickening of the breast is produced by lymphedema usually secondary to obstruction of the axillary lymphatics. On physical examination, the affected breast is, due to increased fluid content, larger, heavier, and of higher overall density. Mammography reveals an increased coarse reticular pattern. Thickening of the skin can have many causes. It may be a result of tumor invasion or a tumor in the dermal lymphatics ; or because of lymphatic congestion through obstruction of lymphatic drainage within the breast, in the axilla, or centrally in the mediastinum. Further causes may be congestive heart failure, benign inflammation, primary skin processes such as psoriasis, or systemic diseases which involve the skin. Mammographic appearance is known to be nonspecific. Ultrasound can demonstrate skin thickening directly, but despite some reports suggesting that the cause of skin thickening can be inferred from the results of ultrasound, this is not usually of practical importance. The purpose of this study is to review the causes of skin thickening of the breast and to use mammography and US to differentiate the causes.

    The intention of the present thesis was the evaluation of a potential parathyroid dysfunction under treatment with radioactive iodine of benign thyroid diseases. It was to be examined whether a change in the parathyroid function would arise within the first week on treatment. So far there are some minor studies existing describing significant changes in the parathyroid hormone serum level within the first months after radioactive iodine therapy of benign and malignant thyroid diseases. Moreover, it is a fact that external beam-radiotherapy can induce neoplasia and that the risk for the subsequent development of primary hyperparathyroidism doubles or triples after external beam-radiotherapy of the head and neck. Up to now, however, an increased incidence for primary hyperparathyroidism following treatment with radioactive iodine ( 131 I) could not be proved. At the department of nuclear medicine of the university hospital Giessen-Marburg GmbH, location Marburg, a prospective cohort study was executed on radioactive iodine therapy of benign thyroid diseases with 105 probands (75 women / 30 men, mean age 60.62 ± 14.3 years). According to their thyroid diseases these 105 probands were classified into following subgroups: thyroid adenoma with 23 patients, multifocal thyroid autonomy with 8 patients, disseminated thyroid autonomy with 37 patients as well as the subgroup Graves' hyperthyroidism (without Graves' ophtalmopathy) and accordingly Graves' disease (with Graves' ophtalmopathy) with 37 patients. The serum level of the intact parathyroid hormone was determined directly before starting the radioactive iodine therapy on the admission day and on day 1, 3 and 5 of the radioactive iodine therapy as well as at the ambulant follow-up examination one month after the start of the therapy. In case of 99 of 105 probands the serum level of parathyroid hormone declined on treatment with 131 I with its nadir on day 3 of therapy (decline by 15.71 ng/l or 27

    Version 4 of the guideline for radioiodine therapy for benign thyroid diseases includes an interdisciplinary consensus ondecision making for antithyroid drugs, surgical treatment and radioiodine therapy. The quantitative description of a specific goiter volume for radioiodine therapy or operation was cancelled. For patients with nodular goiter with or without autonomy, manifold circumstances are in favor of surgery (suspicion on malignancy, large cystic nodules, mediastinal goiter, severe compression of the trachea) or in favor of radioiodine therapy (treatment of autonomy, age of patient, co-morbidity, history of prior subtotal thyroidectomy, profession like teacher, speaker or singer). For patients with Graves' disease, radioiodine therapy or surgery are recommended in the constellation of high risk of relapse (first-line therapy), persistence of hyperthyroidism or relapse of hyperthyroidism. After counseling, the patient gives informed consent to the preferred therapy. The period after radioiodine therapy of benign disorders until conception of at least four months was adapted to the European recommendation. (orig.)

    AIM: To analyze the difference in disease course and need for surgery in patients with Crohn’s disease (CD). METHODS: Data of 506 patients with incident CD were analyzed (age at diagnosis: 31.5 ± 13.8 years). Both hospital and outpatient records were collected prospectively with a complete clinical follow-up and comprehensively reviewed in the population-based Veszprem province database, which includes incident CD patients diagnosed between January 1, 1977 and December 31, 2008. Follow-up data were collected until December 31, 2009. All patients included had at least 1 year of follow-up available. Patients with indeterminate colitis at diagnosis were excluded from the analysis. RESULTS: Overall, 73 patients (14.4%) required resective surgery within 1 year of diagnosis. Steroid exposure and need for biological therapy were lower in patients with early limited surgery (P < 0.001 and P = 0.09). In addition, surgery rates during follow-up in patients with and without early surgery differed significantly after matching on propensity scores (P < 0.001, HR = 0.23). The need for reoperation was also lower in patients with early limited resective surgery (P = 0.038, HR = 0.42) in a Kaplan-Meier and multivariate Cox regression (P = 0.04) analysis. However, this advantage was not observed after matching on propensity scores (PLogrank = 0.656, PBreslow = 0.498). CONCLUSION: Long-term surgery rates and overall exposure to steroids and biological agents were lower in patients with early limited resective surgery, but reoperation rates did not differ.

    recognized uPARAP in Western blotting and gave a strong signal in immunohistochemistry. The immunohistochemic localization pattern was found to be identical to that of uPARAP mRNA as determined in parallel by in situ hybridization. uPARAP expression was then studied in both benign and malignant breast...... conclude that expression of uPARAP is associated with the abnormal breast and that expression appears in myofibroblasts, macrophages and myoepithelium.

    Objectives  To demonstrate the initial experience of robotic hysterectomy to treat benign uterine disease at a university hospital in Brazil. Methods  A cross-sectional study was conducted to review data from the first twenty patients undergoing robotic hysterectomy at our hospital. The surgeries were performed from November 2013 to August 2014, all of them by the same surgeon. The patients were reviewed for preoperative characteristics, including age, body mass index (BMI), indications for the hysterectomy and previous surgeries. Data of operative times, complications, postoperative pain and length of hospital stay were also collected. Results  The total operating room time was 252.9 minutes, while the operative time was 180.7 minutes and the console time was 136.6 minutes. Docking time was 4.2 minutes, and the average undocking time was 1.9 minutes. There was a strong correlation between the operative time and the patient's BMI ( r  = 0.670; p  = 0.001). The console time had significant correlation with the uterine weight and the patient's BMI ( r  = 0.468; p  = 0.037). A learning curve was observed during docking and undocking times. Conclusion  Despite its high cost, the robotic surgery is gaining more space in gynecological surgery. By the results obtained in our hospital, this surgical proposal proved to be feasible and safe. Our initial experience demonstrated a learning curve in some ways. Thieme Publicações Ltda Rio de Janeiro, Brazil.

    Intuitive segmentation-based CADx/radiomic features, calculated from the lesion segmentations of dynamic contrast-enhanced magnetic resonance images (DCE-MRIs) have been utilized in the task of distinguishing between malignant and benign lesions. Additionally, transfer learning with pre-trained deep convolutional neural networks (CNNs) allows for an alternative method of radiomics extraction, where the features are derived directly from the image data. However, the comparison of computer-extracted segmentation-based and CNN features in MRI breast lesion characterization has not yet been conducted. In our study, we used a DCE-MRI database of 640 breast cases - 191 benign and 449 malignant. Thirty-eight segmentation-based features were extracted automatically using our quantitative radiomics workstation. Also, 2D ROIs were selected around each lesion on the DCE-MRIs and directly input into a pre-trained CNN AlexNet, yielding CNN features. Each method was investigated separately and in combination in terms of performance in the task of distinguishing between benign and malignant lesions. Area under the ROC curve (AUC) served as the figure of merit. Both methods yielded promising classification performance with round-robin cross-validated AUC values of 0.88 (se =0.01) and 0.76 (se=0.02) for segmentationbased and deep learning methods, respectively. Combination of the two methods enhanced the performance in malignancy assessment resulting in an AUC value of 0.91 (se=0.01), a statistically significant improvement over the performance of the CNN method alone.

    To determine the accuracy of a probably benign assessment of non-palpable breast lesions (BI-RADS category 3) at mammography and/or ultrasound with immediate histological work-up. Stereotactic or ultrasound guided core needle breast biopsy (NBB) was performed to evaluate 288 lesions, which were prospectively assessed as BI-RADS category 3. Imaging findings included 195 masses, 73 calcification cases, 16 focal asymmetries, and four architectural distortion cases. After NBB, patients underwent either open surgical biopsy (OSB) (n=204) or mammographic follow-up (n=84) for at least 24 months. Histological results of NBB were compared with those of OSB. Three of the 288 lesions (1.0%) proved to be malignant at histological work-up, two of them were ductal carcinoma in situ (DCIS) and one of them was an invasive carcinoma. NBB revealed invasive carcinoma in 1/288 (0.35%) and atypical ductal hyperplasia (ADH) in 13/288 (4.5%) lesions. OSB revealed DCIS in 2/204 (1%) and invasive carcinoma in 1/204 (0.5%) lesions. The two DCIS were underestimated as ADH by NBB. The remaining 285 (99%) lesions proved to be benign at OSB or remained stable during follow-up. Confirmed by tissue diagnosis, the low likelihood of malignancy of prospectively assessed probably benign lesions is below the 2% threshold established for BI-RADS category 3. Imaging follow-up is a safe and effective alternative to immediate histological work-up for such lesions. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

    To determine whether two-view shear-wave elastography (SWE) improves the performance of radiologists in differentiating benign from malignant breast masses compared with single-view SWE. This prospective study was conducted with institutional review board approval, and written informed consent was obtained. B-mode ultrasonographic (US) and orthogonal SWE images were obtained for 219 breast masses (136 benign and 83 malignant; mean size, 14.8 mm) in 219 consecutive women (mean age, 47.9 years; range, 20-78 years). Five blinded radiologists independently assessed the likelihood of malignancy for three data sets: B-mode US alone, B-mode US and single-view SWE, and B-mode US and two-view SWE. Interobserver agreement regarding Breast Imaging Reporting and Data System (BI-RADS) category and the area under the receiver operating characteristic curve (AUC) of each data set were compared. Interobserver agreement was moderate (κ = 0.560 ± 0.015 [standard error of the mean]) for BI-RADS category assessment with B-mode US alone. When SWE was added to B-mode US, five readers showed substantial interobserver agreement (κ = 0.629 ± 0.017 for single-view SWE; κ = 0.651 ± 0.014 for two-view SWE). The mean AUC of B-mode US was 0.870 (range, 0.855-0.884). The AUC of B-mode US and two-view SWE (average, 0.928; range, 0.904-0.941) was higher than that of B-mode US and single-view SWE (average, 0.900; range, 0.890-0.920), with statistically significant differences for three readers (P ≤ .003). The performance of radiologists in differentiating benign from malignant breast masses was improved when B-mode US was combined with two-view SWE compared with that when B-mode US was combined with single-view SWE. © RSNA, 2013

    In order to investigate the expression of leptin receptors mRNA in breast tissue and plasma leptin levels in breast cancer patients with obesity and their relationship with clinical pathologic data, 124 subjects who were either obesity or had suffered from breast benign disease with obesity, or breast cancer with obesity were entered into this study. The levels of plasma leptin in all subjects were determined and leptin receptors mRNA expression levels were measured by RT-PCR in breast tissue of breast cancer patients with obesity and breast benign disease with obesity. The results showed that plasma leptin levels in breast cancer patients with obesity were significantly higher than those in breast benign disease with obesity and obesity patients alone (P<0.05). The expression of the leptin receptor long form [-Lep-R(L)-] mRNA and the leptin receptor short form [-Lep-R(S)-] mRNA in breast tissue of breast cancer patients with obesity were significantly higher than that in breast tissue of breast benign disease patients with obesity (P<0.05). The plasma leptin level had remarkable positive correlation with the expressions of the Lep-R(L) mRNA and the Lep-R(S) mRNA. The plasma leptin level and leptin receptors mRNA expression levels in patients were not correlated with the axillary node metastasis, menopause, the TNM stage or pathological type. Therefore, leptin may have a promoting effect on the carcinogenesis of breast cancer. (authors)

    Fibrocystic disease of the breast is a frequent cause of abnormal mammogram and ultrasonogram in patients with breast pain. The differentiation of fibrocystic disease form fibroadenoma or carcinoma is often difficult. The present study was performed to evaluate the mammographic and sonographic features of fibrocystic disease of the breast Mammograms and sonogram s of 45 patients with pathologically proven fibrocystic disease of breast were analyzed and correlated retrospectively with the pathologic specimens. Clinically the patients had palpable breast lumps or focal skin thickening. The patients were aged 19 to 64 years(average, 37 years) Histologic examination of 29 patients with abnormal findings in mammograms and/or sonograms revealed stromal fibrosis in 28(97%), cyst formation in 24(83%), epithelial hyperplasia in 29(90%), apocrine metaplasia in 7 (24%), chronic inflammation in 15 (52%), fibroadenomatous change in 2 (7%), large pseudocyst formation in 2 (7%), calcification in 1 (3%), and/or chondroid maseptol in 1 (3%). Of 43 patients with mammograms, 23 showed no detectable lesion, even in retrospect, because of dense mammograms there were well marginated mass in 7, poorly marginated mass in 4, multiple small nodules in 2, mixed density radio opaque mass in 3, radiolucent mass in one, and asymmetrical dense breast in 3. One case had calcification within the mass, and another one had very high density nodules that showed chondroid metaplasia. In 14 patients with sonograms, the echogenicity was variable; anechoic in 2, hypoechoic in 8, isoechoic in 3, or mixed echoic in one. The shape of the lesion was round in 2, ovoid in 8, tubular in 2, and irregular in 2. The margin was well marginated in 11 and poorly marginated in 3. Fibrocystic breast disease, which is a frequent cause of breast lumps, has variable findings in mammograms and sonograms. Therefore, fibrocystic disease should be included in the differential diagnosis of breast mass when the typical

    Fibrocystic disease of the breast is a frequent cause of abnormal mammogram and ultrasonogram in patients with breast pain. The differentiation of fibrocystic disease form fibroadenoma or carcinoma is often difficult. The present study was performed to evaluate the mammographic and sonographic features of fibrocystic disease of the breast Mammograms and sonogram s of 45 patients with pathologically proven fibrocystic disease of breast were analyzed and correlated retrospectively with the pathologic specimens. Clinically the patients had palpable breast lumps or focal skin thickening. The patients were aged 19 to 64 years(average, 37 years) Histologic examination of 29 patients with abnormal findings in mammograms and/or sonograms revealed stromal fibrosis in 28(97%), cyst formation in 24(83%), epithelial hyperplasia in 29(90%), apocrine metaplasia in 7 (24%), chronic inflammation in 15 (52%), fibroadenomatous change in 2 (7%), large pseudocyst formation in 2 (7%), calcification in 1 (3%), and/or chondroid maseptol in 1 (3%). Of 43 patients with mammograms, 23 showed no detectable lesion, even in retrospect, because of dense mammograms there were well marginated mass in 7, poorly marginated mass in 4, multiple small nodules in 2, mixed density radio opaque mass in 3, radiolucent mass in one, and asymmetrical dense breast in 3. One case had calcification within the mass, and another one had very high density nodules that showed chondroid metaplasia. In 14 patients with sonograms, theechogenicity was variable ; anechoic in 2, hypoechoic in 8, isoechoic in 3, or mixed echoic in one. The shape of the lesion was round in 2, ovoid in 8, tubular in 2, and irregular in 2. The margin was well marginated in 11 and poorly marginated in 3. Fibrocystic breast disease, which is a frequent cause of breast lumps, has variable findings in mammograms and sonograms. Therefore, fibrocystic disease should be included in the differential diagnosis of breast mass when the typical

    Benign thyroid disease ranks by far as the most frequent therapy in nuclear medicine. In Germany approximately 25 000 cases of hyperthyreosis are being treated in association with autonomy or Graves` disease, but also for the reduction of goiters or the correction of latent functional disturbances. In such indications radiotherapy is virtually free of risk as opposed to surgery and ranks more favorable in regard to costs and curative effects versus pharmacological long term treatment. Still regional varying therapeutical concepts and intentions are being pursued and trials of improvements described. There is consent in therapy that quality of treatment is closely linked to a specialized out-door platient preparation, individual hospital activity dosage and lifelong follow up including continued evaluation of therapeutical results. In this paper minimal requirements of outpatient measures before and after therapy are summarized which in Germany is only permitted on an inhospital patient basis. Considering basics of radioactive preventive law, scientific evidence of available results of therapeutical studies and a survey of German therapeutic centers, suggestions for a quality maintaining management in view of the most effective utilization for the limited available number of beds is presented for discussion.

    Objective: To assess the CT perfusion characteristics of breast diseases. Methods: Twenty-two patients with fibroadenoma accompanied with cyst (n=1), other benign diseases (n=5), and carcinomas (n=16) underwent breast CT scan. CT perfusion was performed for breast with cine mode (0.5 s per rotation ) on a multislice CT scanner, 120 kV, 60 mA, 4 x 5 mm collimation. Contrast injection was done by using 50 ml nonionic contrast agent (300 mg I/ml ), at a flow rate of 4 ml/s with a power injector, 5 seconds delay, and data acquisition lasted for 50 seconds. These data were processed on a GE AW 4.1 workstation using perfusion 3 software package, and the mean BF, BV, MTT and PS were measured and statistically analyzed. Results: The mean BF, BV, MTT and PS in carcinoma were (33.55 ± 28.40) ml·min -1 ·100 g -1 , (5.60±3.08) ml/100 g, (15.37±6.41) s, (18.71±10.42) ml· min -1 ·100 g -1 . The mean BF, BV, MTT and PS in contralateral normal breast of carcinoma were (10.36 ± 9.44) ml·min -1 ·100 g -1 , (0.70±0.22) ml/100 g, (13.55 ± 7.27) s, (1.54±1.74) ml·min -1 ·100 g -1 . The mean BF, BV, and PS between carcinoma and normal breast were statistically significant (P 0.05). The mean BF, BV, MTT and PS in fibroadenoma were (62.57 ± 19.62) ml·min -1 ·100 g -1 , (7.37 ±1.30) ml/100 g, (11.24 ± 3.34) s, (27.63 ± 3.87) ml·min -1 ·100 g -1 . The mean PS between carcinoma and fibroadenoma was statistically significant (P 0.05). The mean BF, BV, MTT and PS in benign lesion were (7.65 ± 10.24) ml·min -1 ·100 g -1 , (1.23 ± 0.97) ml/100 g, (14.94 ± 10.68) s, (1.81 ± 1.72) ml·min -1 ·100 g -1 . The mean BF, BV, and PS between carcinoma and benign lesion were statistically significant (P 0.05). Conclusion: MSCT perfusion may reflect the features of breast diseases, and provide valuable hemodynamic message. These parameters have a value in diagnosis of breast diseases and are helpful for differential diagnosis. (authors)

    Objective: To evaluate the value of SPECT/CT in assessment of femoral foci of abnormal bone metabolism classified as intermediated on bone scanning using 99Tcm-methylene diphosphonate (MDP). Methods: There were 94 patients with solitary femoral abnormal uptake in bone scanning included. SPECT was accompanied by inline CT over the femoral region. All of the images were blindly interpreted independently by two experienced board-certified radiologists. The reference standard was follow-up over half a year of MRI, CT, SPECT, or pathology. Diagnosis which consist with reference were counted as accurate. Diagnosis which either not consist with reference or undetermined were counted as false. Results: Of the 94 patients, 78 patients (male 42 , female 36, mean age 62 yrs) have the definite diagnosis of their femoral foci. 19 were proved to be metastasis and the other 59 were benign diseases. The diagnostic accuracy by bone SPECT, bone CT and fusion imaging were 58.9%, 87.2%, 96.2% respectively. Conclusions: Most of the solitary femoral foci caused by benign diseases. SPECT/CT using 99 Tc m -MDP has additional valuable in differentiating malignancy from benignancy in femoral foci . (authors)

    To compare the diagnostic performance of strain and shear wave elastography of breast masses for quantitative assessment in differentiating benign and malignant lesions and to evaluate the diagnostic accuracy of combined strain and shear wave elastography. Between January and February 2016, 37 women with 45 breast masses underwent both strain and shear wave ultrasound (US) elastographic examinations. The American College of Radiology Breast Imaging Reporting and Data System (BI-RADS) final assessment on B-mode US imaging was assessed. We calculated strain ratios for strain elastography and the mean elasticity value and elasticity ratio of the lesion to fat for shear wave elastography. Diagnostic performances were compared by using the area under the receiver operating characteristic curve (AUC). The 37 women had a mean age of 47.4 years (range, 20-79 years). Of the 45 lesions, 20 were malignant, and 25 were benign. The AUCs for elasticity values on strain and shear wave elastography showed no significant differences (strain ratio, 0.929; mean elasticity, 0.898; and elasticity ratio, 0.868; P > .05). After selectively downgrading BI-RADS category 4a lesions based on strain and shear wave elastographic cutoffs, the AUCs for the combined sets of B-mode US and elastography were improved (B-mode + strain, 0.940; B-mode + shear wave; 0.964; and B-mode, 0.724; P shear wave elastography showed significantly higher diagnostic accuracy than each individual elastographic modality (P = .031). These preliminary results showed that strain and shear wave elastography had similar diagnostic performance. The addition of strain and shear wave elastography to B-mode US improved diagnostic performance. The combination of strain and shear wave elastography results in a higher diagnostic yield than each individual elastographic modality. © 2017 by the American Institute of Ultrasound in Medicine.

    Granulomatous lobular mastitis is a rare chronic inflammatory disease of the breast. The differential diagnosis with malign breast disease is often not easy. In most cases a surgical biopsy is needed for correct diagnosis. Idiopathic granulomatous mastitis is an exclusion diagnosis, based on the demonstration of a characteristic histological pattern, combined with the exclusion of other possible causes of granulomatous breast lesions. There is still no generally accepted optimal treatment. If surgery forms part of the treatment, a conservative approach seems to be adequate in most cases. Another option is a long-term steroid treatment. It is mandatory to exclude infectious causes of granulomatous mastitis before corticoid therapy is started.

    Celiac disease is a chronic immune-mediated enteropathy in which dietary gluten induces an inflammatory reaction predominantly in the duodenum. Celiac disease is known to be associated with benign small bowel thickening and reactive lymphadenopathy that often regresses after the institution of a gluten-free diet. A 66-year-old male patient with celiac disease presented with abdominal pain and diarrheal illness. Computerized tomography of the abdomen revealed a duodenal mass. Endoscopic ultrasound-guided fine needle aspiration of the mass revealed bizarre stromal cells which represent a nonspecific tissue reaction to inflammation. This inflammatory mass regressed after the institution of a gluten-free diet. This case report describes a unique presentation of celiac disease in the form of a granulomatous self-regressing mass. Also, this is the first reported case of bizarre stromal cells found in association with celiac disease. In addition to lymphoma and small bowel adenocarcinoma, celiac disease can present with a benign inflammatory mass, which should be serially monitored for resolution with a gluten-free diet.

    The objective of this study was to present the initial operative experience of solo surgeon single-port laparoscopic surgery (SPLS) in the laparoscopic treatment of benign gynecologic diseases and to investigate its feasibility and surgical outcomes. Using a novel homemade laparoscope-anchored instrument system that consisted of a laparoscopic instrument attached to a laparoscope and a glove-wound retractor umbilical port, we performed solo surgeon SPLS in 13 patients between March 2011 and June 2012. Intraoperative complications and postoperative surgical outcomes were determined. The primary operative procedures performed were unilateral salpingo-oophorectomy (n = 5), unilateral salpingectomy (n = 2), adhesiolysis (n = 1), and laparoscopically assisted vaginal hysterectomy (n = 5). Additional surgical procedures included additional adhesiolysis (n = 4) and ovarian drilling (n = 1).The primary indications for surgery were benign ovarian tumors (n = 5), ectopic pregnancy (n = 2), pelvic adhesion (infertility) (n = 1), and benign uterine tumors (n = 5). Solo surgeon SPLS was successfully accomplished in all procedures without a laparoscopic assistant. There were no intraoperative or postoperative complications. Our laparoscope-anchored instrument system obviates the need for an additional laparoscopic assistant and enables SPLS to be performed by a solo surgeon. The findings show that with our system, solo surgeon SPLS is a feasible and safe alternative technique for the treatment of benign gynecologic diseases in properly selected patients.

    The intention of the present thesis was the evaluation of a potential parathyroid dysfunction under treatment with radioactive iodine of benign thyroid diseases. It was to be examined whether a change in the parathyroid function would arise within the first week on treatment. So far there are some minor studies existing describing significant changes in the parathyroid hormone serum level within the first months after radioactive iodine therapy of benign and malignant thyroid diseases. Moreover, it is a fact that external beam-radiotherapy can induce neoplasia and that the risk for the subsequent development of primary hyperparathyroidism doubles or triples after external beam-radiotherapy of the head and neck. Up to now, however, an increased incidence for primary hyperparathyroidism following treatment with radioactive iodine ({sup 131}I) could not be proved. At the department of nuclear medicine of the university hospital Giessen-Marburg GmbH, location Marburg, a prospective cohort study was executed on radioactive iodine therapy of benign thyroid diseases with 105 probands (75 women / 30 men, mean age 60.62 ± 14.3 years). According to their thyroid diseases these 105 probands were classified into following subgroups: thyroid adenoma with 23 patients, multifocal thyroid autonomy with 8 patients, disseminated thyroid autonomy with 37 patients as well as the subgroup Graves' hyperthyroidism (without Graves' ophtalmopathy) and accordingly Graves' disease (with Graves' ophtalmopathy) with 37 patients. The serum level of the intact parathyroid hormone was determined directly before starting the radioactive iodine therapy on the admission day and on day 1, 3 and 5 of the radioactive iodine therapy as well as at the ambulant follow-up examination one month after the start of the therapy. In case of 99 of 105 probands the serum level of parathyroid hormone declined on treatment with {sup 131}I with its nadir on day 3 of therapy (decline by 15.71 ng

    To investigate the diagnostic efficiency of decline rate of signal intensity and apparent diffusion coefficient with different b values for differentiating benign and malignant breast lesions on diffusion-weighted 3.0 T magnetic resonance imaging. A total of 152 patients with 162 confirmed histopathologically breast lesions (85 malignant and 77 benign) underwent 3.0 T diffusion-weighted magnetic resonance imaging. Four b values (0, 400, 800 and 1 000 s/mm²) were used. The signal intensity and ADC values of breast lesions were measured respectively. The signal intensity decline rate (SIDR) and apparent diffusion coefficient decline rate (ADCDR) were calculated respectively. SIDR = (signal intensity of lesions with low b value-signal intensity of lesions with high b value)/signal intensity of lesions with low b value, ADCDR = (ADC value of lesions with low b value-ADC value of lesions with high b value) /ADC value of lesions with low b value. The independent sample t-test was employed for statistical analyses and the receiver operating characteristic (ROC) curve for evaluating the diagnosis efficiency of SIDR and ADCDR values. Significant differences were observed in SIDR between benign and malignant breast lesions with b values of 0-400, 400-800 and 800-1 000 s/mm². The sensitivities of SIDR for differentiating benign and malignant breast lesions were 61.2%, 68.2% and 67.1%, the specificities 74.0%, 85.7% and 67.5%, the diagnosis accordance rates 67.3%, 76.5% and 67.3%, the positive predictive values 72.2%, 84.1% and 69.5% and the negative predictive values 63.3%, 71.0% and 65.0% respectively. Significant differences were observed in ADCDR between benign and malignant breast lesions with b values of 400-800 s/mm² and 800-1 000 s/mm². The sensitivities of SDR for differentiating benign and malignant breast lesions were 80.0% and 65.9%, the specificities 72.7% and 65.0%, the diagnostic accordance rates 76.5% and 65.4%, the positive predictive values 76.4% and 67

    To assess whether the BI-RADS classification in MR-Mammography (MRM) can distinguish between benign and malignant lesions. 207 MRM investigations were categorised according to BI-RADS. The results were compared to histology. All MRM studies were interpreted by two examiners. Statistical significance for the accuracy of MRM was calculated. A significant correlation between specific histology and MRM-tumour-morphology could not be reported. Mass (68%) was significant for malignancy. Significance raised with irregular shape (88%), spiculated margin (97%), rim enhancement (98%), fast initial increase (90%), post initial plateau (65%), and intermediate T2 result (82%). Highly significant for benignity was an oval mass (79%), slow initial increase (94%) and a hyperintense T2 result (77%), also an inconspicuous MRM result (77%) was often seen in benign histology. Symmetry (90%) and further post initial increase (90%) were significant, whereas a regional distribution (74%) was lowly significant for benignity. On basis of the BI-RADS classification an objective comparability and statement of diagnosis could be made highly significant. Due to the fact of false-negative and false-positive MRM-results, histology is necessary. (orig.)

    In this study 39 cases of abdominal benign disease were examined by PET using [sup 18]F-fluorodeoxyglucose (FDG), and 11 cases of them (i.e. 4 cases of liver abscess, 1 of pelvic abscess, 1 of omental abscess, 2 of chronic pancreatitis, 1 of inflammatory pseudotumor of liver, 1 of retroperitoneal leiomyoma and 1 of solid and cystic tumor of pancreas) which showed as high accumulation of FDG as malignant lesion were investigated of their clinical and pathological feature. We used Ci/Cp ratio as index to express the accumulation of FDG in the lesion, which was calculated from radioactivities of the lesion (Ci) and the plasma (Cp) at 60 mins after injection of FDG. The Ci/Cp ratio of the 11 cases was 3.64[+-]0.77. The pathological feature of the 9 inflammatory cases was high accumulation of inflammatory cells and that of the 2 benign tumor cases was solid proliferation of tumor cells. The serum of the 9 inflammatory cases showed high CRP value. It was considered that the high accumulation of FDG in inflammatory lesions was due to piles of FDG uptake of the many inflammatory cells, while the 2 benign tumors of high accumulation were considered that the tumor cell had as high glucose metabolism as malignancies.

    2013-01-01

    Full Text Available Introduction. Developments in immunological and quantitative real-time PCR-based analysis have enabled the detection, enumeration, and characterization of circulating tumor cells (CTCs. It is assumed that the detection of CTCs is associated with cancer, based on the finding that CTCs can be detected in all major cancer and not in healthy subjects or those with benign disease. Methods and Patients. Consecutive men, with suspicion of prostate cancer, had blood samples taken before prostate biopsy; mononuclear cells were obtained using differential gel centrifugation and CPCs detecting using anti-PSA immunocytochemistry. Positive samples underwent further classification with anti-P504S. Results. 329 men underwent prostate biopsy; of these men 83 underwent a second biopsy and 44 a third one. Of those with a biopsy negative for cancer, 19/226 (8.4% had CPCs PSA (+ P504S (− detected at first biopsy, 6/74 (8.1% at second biopsy, and 5/33 (15.2% at third biopsy. Men with cancer-positive biopsies did not have PSA (+ P504S (− CPCs detected. These benign cells were associated with chronic prostatitis. Conclusions. Patients with chronic prostatitis may have circulating prostate cells detected in blood, which do not express the enzyme P504S and should be thought of as benign in nature.

    Bile acids have been implicated in the development of gastrointestinal malignancies. Both the specific nature of individual bile acids and their concentration appear key factors in the carcinogenic potency of bile. Using liquid chromatography mass spectrometry (LC-MS) we performed quantitative profiling of bile extracted directly from the common bile duct in 30 patients (15 patients with pancreatic cancer and 15 patients with benign disease). Separation and detection of bile acids was performed using a 1.7μm particle size reversed-phase C 18 LC column at a flow rate of 200μL/min with negative electrospray ionization MS. A significant difference (p=0.018) was seen in the concentration of unconjugated cholic acid in the malignant group (0.643mmol/L) compared to the benign group (0.022mmol/L), with an overall significant difference (p=0.04) seen in the level of total unconjugated bile acids in the malignant group (1.816mmol/L) compared to the benign group (0.069mmol/L). This finding may offer the possibility of both understanding the biology of cancer development in the pancreas, as well as offering a potential diagnostic avenue to explore. However, a larger study is necessary to confirm the alterations in bile acid profiles reported here and explore factors such as diet and microbial populations on the bile acid profiles of these patient groups.

Methoden: Die Studie umfasst folgende Kollektive: 250 gesunde Probanden, 50 Patienten mit euthyreoter Struma diffusa, 161 Patienten mit euthyreoter Knotenstruma (davon 108 operierte Faelle, wobei sich 17 Karzinome fanden), 60 hyperthyreote Patienten mit autonomer Knotenstruma, 150 Patienten mit Thyreoiditis Hashimoto und 30 hyperthyreote Patienten mit M. Basedow. Ergebnisse: Die Grenze des Referenzbereichs errechnete sich zu 30 ng Tg/ml. Die Analyse der diffusen Strumen zeigte eine lineare Abhaengigkeit des Tg-Spiegels von der Schilddruesengroesse, wobei der Erwartungswert in etwa dem Organvolumen in ml entsprach. Knotige Veraenderungen fuehrten zu einem ueberproportionalen Tg-Anstieg, der allerdings einer grossen Varianz unterlag und daher im Einzelfall nur schwer abzuschaetzen war. Von den 17 Patienten mit Schilddruesenkarzinom lag der Tg-Spiegel in 10 Faellen unterhalb des Erwartungswertes, 2 Patienten zeigten einen Tg-Wert von >1000 ng/ml. Bei Autonomien fand sich bezogen auf eine durch Substitution extrem supprimierte Vergleichsgruppe ein signifikant hoeherer mittlerer Tg-Spiegel. Aufgrund der hohen Varianz der Tg-Werte beider Kollektive war die Diagnose der Autonomie anhand der Tg-Bestimmung jedoch kaum moeglich. In der Gruppe mit Thyreoiditis Hashimoto zeigte sich im Vergleich zum Normalkollektiv ein erniedrigter Tg-Spiegel. Bei M. Basedow war die mittlere Tg-Konzentration signifikant hoeher als in der Vergleichsgruppe mit Struma diffusa, dennoch lagen 47% aller Werte noch im Referenzbereich. Schlussfolgerung: Hohe Tg-Werte fuehren bei Verdacht auf Malignitaet, Autonomie oder M. Basedow zu einer hoeheren

    Besides individual care, regular follow-up studies in breast cancer patients have different aims, relative to different tumor stages at presentation. In early stages emphasis has to be laid on detection of loco-regional recurrences, which will not reduce overall survival if diagnosed and treated early. In addition, treatment effects and changes in the activity of disease are evaluated. Radiographic studies for detection of distant metastases are justified if followed by proper treatment. Early diagnosis of cancer of the opposite breast and of such cancers that are associated with breast cancer (colon, ovaries, endometrium) is imperative. The aim of a regular follow-up in more advanced tumor stages is to monitor the extent of disease and to prevent complications (e.g. fractures, spinal cord compression). In familial breast cancer first degree relatives should be included in the follow-up plan. The patient's psychosocial needs, even if not verbalized, should not be neglected. (Author)

    Purpose: Atypical hyperplasia (AH) (ductal or lobular) represents a marker for an increased risk for subsequent breast cancer in either breast, especially in premenopausal women and those with a positive family history. However, the impact of the presence of AH in association with an invasive breast cancer on ipsilateral breast recurrence rates or contralateral breast cancer in women treated with conservative surgery and radiation is unknown. For a number of clinicians the presence of marked proliferative changes with atypia at the time of diagnosis of an invasive cancer is an indication for mastectomy. In an attempt to address this issue, we compared the outcome of patients (pts) with proliferative disease with atypia to those in whom this pathologic feature was absent. Materials and Methods: From 1982-1994, 1537 women with stage I-II breast cancer underwent excisional biopsy, axillary dissection and radiation. 459 of these women had pathologic evaluation of the background adjacent benign breast tissue and represent the study population. The median followup was 6.3 yrs (range .1-14.5). The median age was 55 yrs (range 24 to 88). 23% had positive axillary nodes. 25% received adjuvant chemotherapy (CMF or CAF) with (9%) or without (16%) tamoxifen. 24% received tamoxifen alone. The study population was divided into 2 groups: 131 pts with atypical hyperplasia (ductal 99 pts, lobular 20 pts, and type not specified 12 pts) and 328 pts with no proliferative changes or proliferative changes without atypia. The comparability of the 2 groups was assessed for the following factors: clinical (race, age, menopausal status, method of detection of primary, primary tumor size, and family history), pathologic (histology, final resection margin, pathologic nodal status, presence or absence of LCIS, histologic subtype DCIS when present and estrogen and progesterone receptor status) and treatment related (re-excision and adjuvant chemotherapy and/or tamoxifen). Outcome was evaluated

    The purpose of this study is to evaluate thallium scanning as a potential test in differentiating malignant from benign lesions of breast. Thirty-one female patients underwent thallium scan of the breast. After intravenous injection of 74-111 MBq(2-3 mCi)of thallium-201, anterior and lateral images were obtained. We compared thallium scans with pathological results. Of 11 patients with breast cancers, 10 cases (90.9%) were detected using thallium scan. Thallium scan obtained in one patient who had breast cancer but received several cycles of chemotherapy did not show thallium uptake. The smallest detectable cancer was 1.5 cm in diameter. In contrast, there is no thallium accumulation in breasts of 17 of 20 patients with benign disease (85%), Three cases of 13 fibrocystic disease show thallium uptake in their breast. In conclusion, thallium scan is an effective test in differentiating benign from malignant lesion.

    The Nuclear Medicine Section of the IAEA has a long tradition in supporting the implementation of effective therapeutic application for the management of cancer and benign conditions. This obligation resides in Article II of the IAEA Statutes. The specific mission is to foster the application of nuclear medicine techniques in those diseases that may successfully be managed using radioisotopic applications. In addition to documents related to therapeutic application of unsealed radioisotopes, the IAEA was successful in managing a multicentre Coordinated Research Projects (CRPs) for the treatment of Hepato Cellular Carcinoma published recently in a special edition of the Seminars. Other CRPSs were aimed at improving quality of life of patients suffering from rheumatoid arthritis and haemophilic arthropathy and the palliation of disseminated metastatic bone pain. In addition, to disseminate knowledge, high level experts are invited to consultancy panels to assist in producing relevant documents in the field of Nuclear Medicine, including publications, manuals and educational material all of which are accessible on-line. The Department of Nuclear Sciences and Application (NA) has identified the need to enhance the availability and accessibility of Member States to medical radioisotopes potentially attractive for clinical use, one of these being Lutetium-177. To achieve this objective a world-wide network of cooperation was established. Since several countries operating nuclear reactors at a low to medium-neutron flux are capable of producing sufficient amounts of Lu-177 for the labelling of bone seeking radiopharmaceuticals, Lu-177 ethylenediamine tetra(methylene phosphonic acid) ( 177 Lu-EDTMP) has been identified for its clinical potential as a safe, sustainable and cost-effective radiopharmaceutical for the management of bone pain caused by metastatic prostate and breast cancer. To fulfil the highest standards of international legal requirements, animal studies and

    With increasing availability many centers are deploying expandable metallic stents to manage patients with diverse endobronchial disorders. Although these devices have an important role in malignant disease their usefulness in benign large airway disorders is less defined. Between 1997 and 2005, 31 patients aged 34 to 83 years with benign large airway compromise secondary to tracheomalacia (n = 7), posttracheostomy stricture (n = 8), posttracheostomy rupture (n = 2), postpneumonectomy bronchopleural fistula (n = 2), stricture after lung transplantation (n = 3), lobectomy, tuberculosis, traumatic injury to right main bronchus (n = 1 patient each), and external compression of the airway secondary to achalasia, multinodular goiter, aortic aneurysm, right brachiocephalic artery aneurysm, right interrupted aortic arch, and dissecting aneurysm (n = 1 patient each) who were medically unfit for formal surgical intervention were treated by Ultraflex stent deployment. The range of follow-up was 1 week to 96 months. Stents were deployed under anesthesia using rigid bronchoscopy. Complications included granulation tissue formation (n = 11) treated with Nd: YAG laser ablation, stent migration (n = 1; stent removed, another deployed), metal fatigue (n = 1), stent removal (n = 1), mucus plugging (n = 2), and halitosis (n = 6) difficult to treat despite antibiotics. Thirteen patients died of unrelated causes between 1 week and 15 months after stent deployment. Endobronchial metallic stents should be considered only for selected patients with large airway compromise secondary to benign airway diseases for whom other medical comorbidities contraindicate formal airway surgery. Once deployed, they are difficult to remove, are associated with significant complications, and require prospective bronchoscopic surveillance and often further therapeutic intervention.

    The aim of this study was to design a pattern recognition system for assisting the diagnosis of breast lesions, using image information from Ultrasound (US) and Digital Mammography (DM) imaging modalities. State-of-art computer technology was employed based on commercial Graphics Processing Unit (GPU) cards and parallel programming. An experienced radiologist outlined breast lesions on both US and DM images from 59 patients employing a custom designed computer software application. Textural features were extracted from each lesion and were used to design the pattern recognition system. Several classifiers were tested for highest performance in discriminating benign from malignant lesions. Classifiers were also combined into ensemble schemes for further improvement of the system's classification accuracy. Following the pattern recognition system optimization, the final system was designed employing the Probabilistic Neural Network classifier (PNN) on the GPU card (GeForce 580GTX) using CUDA programming framework and C++ programming language. The use of such state-of-art technology renders the system capable of redesigning itself on site once additional verified US and DM data are collected. Mixture of US and DM features optimized performance with over 90% accuracy in correctly classifying the lesions

    To measure procedure-related hospital readmissions within 30 days after discharge for patients who have a hysterectomy for benign disease. Secondary outcome quality measures evaluated were cost, estimated blood loss, length of stay and sum of costs associated with readmissions. Retrospective cohort study (Canadian Task Force classification II-2). Academic community hospital. Patients who underwent hysterectomy to treat benign disease from January 2008 to December 2012. Patients were grouped according to route of hysterectomy: robotic-assisted laparoscopic hysterectomy (robotic), laparoscopic hysterectomy (laparoscopic), abdominal hysterectomy (open via laparotomy), and vaginal hysterectomy (vaginal). Inclusion criteria were met by 2554 patients: 601 in the robotic group, 427 in the laparoscopic group, 1194 in the abdominal group, and 332 in the vaginal group. Readmission rates in the robotic cohort were significantly less (probotic cohorts: Robotic (1%), laparoscopic (2.5%), open (3.5%), vaginal (2.4%). Estimated blood loss, length of stay, and sum of readmission costs were also significantly less in the robotic cohort (probotic-assisted laparoscopic hysterectomy have a significantly lower chance of readmission robotics cohort also experienced a shorter length of stay, less estimated blood loss, and a cost savings associated with readmissions when compared to non-robotic approaches. Prospective registries describing quality outcomes, total sum of costs including 30 days follow-up, as well as patient-related quality of life benefits are recommended to confirm these findings and determine which surgical route offers the highest patient and societal value.

    Maxwell, A.J.; Mataka, G.; Pearson, J.M.

    2013-01-01

    Aim: To ascertain the negative predictive value (NPV) for atypia and malignancy of 14 G core biopsy of papillomas and to determine whether lesion type influences the likelihood of malignancy at lesion excision. Materials and methods: Ninety-six lesions with a 14 G core biopsy diagnosis of benign papilloma without atypia in 95 women were included. The imaging features (mass or microcalcification), biopsy mode, and number of core samples taken were documented. All patients subsequently underwent lesion excision with either extensive vacuum-assisted biopsy (VAB; 72 lesions) or surgery (24 lesions). Mammographic follow-up of at least 2 years was available for 32 lesions that were benign at VAB. Results: Atypia or malignancy was found more commonly in association with microcalcification (six of 29 lesions: 21%; median number of nine 14 G cores) than a mass (five of 67 lesions: 7%; median number of three 14 G cores), although the difference does not reach statistical significance (p = 0.088). The NPV of a 14 G core biopsy diagnosis of papilloma for atypia or malignancy is 89% (85/96). Disease underestimation may be more common in microcalcification lesions despite the greater number of cores obtained. Conclusion: Excision (using VAB or surgically) of all papillomas diagnosed as benign on 14 G needle core biopsy is recommended. Surgery may be more appropriate than VAB for some microcalcification lesions unless they are small and can be confidently removed in their entirety using VAB

    The treatment of malignant disease of the breast arouses more controversy and emotion than that of any other form of malignant disease. Many clinical trials have been carried out and others are still in progress. In addition, research work continues in regard to other aspects of the disease, such as epidemiology, population screening, and endocrine factors; yet little is really known about the true biological nature of carcinoma of the breast. A vast amount of literature has accumulated on the treatment of ''operable'' carcinoma of the breast, but it is not proposed to discuss here the merits or demerits of the various suggested treatments. Instead this chapter will be confined to the practical management of carcinoma of the breast as seen from the point of view of radiotherapist. For this reason greater attention will be paid to the radiotherapy techniques as practised at the Christie Hospital

    Purpose To investigate the performance of integrated approaches that combined intravoxel incoherent motion (IVIM) and non-Gaussian diffusion parameters compared with the Breast Imaging and Reporting Data System (BI-RADS) to establish multiparameter thresholds scores or probabilities by using Bayesian analysis to distinguish malignant from benign breast lesions and their correlation with molecular prognostic factors. Materials and Methods Between May 2013 and March 2015, 411 patients were prospectively enrolled and 199 patients (allocated to training [n = 99] and validation [n = 100] sets) were included in this study. IVIM parameters (flowing blood volume fraction [fIVIM] and pseudodiffusion coefficient [D*]) and non-Gaussian diffusion parameters (theoretical apparent diffusion coefficient [ADC] at b value of 0 sec/mm 2 [ADC 0 ] and kurtosis [K]) by using IVIM and kurtosis models were estimated from diffusion-weighted image series (16 b values up to 2500 sec/mm 2 ), as well as a synthetic ADC (sADC) calculated by using b values of 200 and 1500 (sADC 200-1500 ) and a standard ADC calculated by using b values of 0 and 800 sec/mm 2 (ADC 0-800 ). The performance of two diagnostic approaches (combined parameter thresholds and Bayesian analysis) combining IVIM and diffusion parameters was evaluated and compared with BI-RADS performance. The Mann-Whitney U test and a nonparametric multiple comparison test were used to compare their performance to determine benignity or malignancy and as molecular prognostic biomarkers and subtypes of breast cancer. Results Significant differences were found between malignant and benign breast lesions for IVIM and non-Gaussian diffusion parameters (ADC 0 , K, fIVIM, fIVIM · D*, sADC 200-1500, and ADC 0-800 ; P < .05). Sensitivity and specificity for the validation set by radiologists A and B were as follows: sensitivity, 94.7% and 89.5%, and specificity, 75.0% and 79.2% for sADC 200-1500 , respectively; sensitivity, 94.7% and 96.1%, and

    Behcet's disease is a vasculitis of unknown origin that was traditionally defined by oral and genital ulcers and uveitis. We describe a case of a patient with a diagnosis of Behcet's syndrome who presented a palpable lesion in the right breast with inflammatory signs. X-ray findings posed a differential diagnosis between tumoral and inflammatory pathology. The pathological findings confirmed a small-vessel vasculitis. We found two reports of breast involvement by this disease in the literature. Our patient was studied by mammogram and sonogram which together with clinical history are important to prevent delay in diagnosis and unnecessary therapeutic procedures. (orig.)

    2015-11-28

    Inflammation is a homeostatic mechanism aiming to maintain tissue integrity. The underlying immunological mechanisms and the interrelationship between ionizing radiation and inflammation are complex and multifactorial on cellular and chemical levels. On the one hand, radiation with single doses exceeding 1 Gy might initiate inflammatory reactions and thereby impact on tumor development. On the other hand, radiation is capable of attenuating an established inflammatory process, which is clinically used for the treatment of inflammatory and degenerative diseases with low-dose radiotherapy (single dose modulates inflammatory events in benign inflammatory and in malign diseases. A special focus is set on the role of tumor infiltrating lymphocytes and macrophages as biomarkers to predict treatment response and anti-tumor immunity and on mechanisms implicated in the anti-inflammatory effects of low-dose radiation therapy.

    1990-12-01

    Radioiodine treatment is considered to be the treatment of choice in benign thyroid diseases because of its very low side effects. Real and hypothetic risks and side effects have to be differentiated. Both may occur early and late after the treatment. Radioiodinethyroiditis in small volumes at high doses is very rare. Exacerbation of a thyroid storm (0.34%) as well as local compressions accompanied with reactive edema of the thyroid are early real side effects of radioiodine treatment. Late real side effects are failure of treatment (7-30% of thyrotoxicosis) and induction of hypothyroidism (4-20% of functional autonomy and increasing frequency in Graves' diseases with time). Late hypothetic risks are somatic (1-9/10000 bis 1-9/100000) or genetic (1-9/100000). An early risk might be the misdiagnosis of an additional thyroid carcinoma. (orig.).

    Cancer of the breast is the second most common cause of cancer in women. Mass in the breast, whether benign or malignant is a cause of anxiety to the patients and the family members. All breast lumps are considered to be carcinomas until proved otherwise and are the causes of concern both for the patient and surgeon. This is a retrospective study conducted in Kathmandu Model Hospital for a total duration of three years from August 2007 to August 2010. 114 sample of breast tissue sent for histopathology were studied. Peak incidence of benign lesion was in between 21-30 years and malignant lesions in between 31-50 years. No breast lesions were seen in the first decade of life. Cancer of the breast was seen in 12.28% of cases. Fibroadenoma and fibrocystic disease were the commonest benign lesion and infiltrating ductal carcinoma was the commonest malignant lesion. Specimens from 10 male breasts were received. Gynaecomastia was the most common lesion encountered in males. Infiltrating ductal carcinoma was seen in a 70 year old male. Breast cancer is one of the commonest causes of breast lump particularly in women and is growing public health problem in Nepal.

  20. Exosomal lncRNAs may to Help Distinguish Prostate Cancer from Benign Disease

    Full Text Available Exosomes are membranous vesicles containing various biomolecules including lncRNAs which are involved in cellular communication and are secreted from many cells including cancer cells. In our study, investigated the exosomal GAS5 and lincRNA-p21 lncRNA levels in urine samples from 30 patients with prostate cancer (PCa and 49 patients with benign prostatic hyperplasia. Quantification of lncRNA molecules was performed by real-time PCR. We observed a significant difference in the exosomal lincRNA-p21 levels between PCa and BPH patients whereas the GAS5 levels did not reveal a difference. Our data suggest that the discriminative potential of exosomal lincRNA-p21 levels may help to improve the diagnostic prediction of the malignant state for patients with prostate cancer.

    Standardisation of the classification of breast imaging reports will improve communication between the referrer and the radiologist and avoid ambiguity, which may otherwise lead to mismanagement of patients. Following wide consultation, Royal College of Radiologists Breast Group has produced a scoring system for the classification of breast imaging. This will facilitate audit and the development of nationally agreed standards for the investigation of women with breast disease. This five-point system is as follows: 1, normal; 2, benign findings; 3, indeterminate/probably benign findings; 4, findings suspicious of malignancy; 5, findings highly suspicious of malignancy. It is recommended that this be used in the reporting of all breast imaging examinations in the UK.

    Many women under age 35 years undergo breast imaging, and the vast majority of studies are normal or compatible with benign disease. In our series of 649 patients aged 13 - 34, the only significant indicators were a palpable mass or infection. In the 383 patients with either of these indications, mammographic and/or US findings were normal in 53%, compatible with benign disease in 14%, and suggestive of malignancy in 33%. Biopsy performed in 80 of these women revealed breast cancer in five (6%). None of the 266 women with low-yield indications (pain, modularity, galactorrhea, fibrocystic disease, screening) had significant imaging findings or clinical or surgical evidence of breast cancer

Materials and methods: Two-hundred-thirty-six male patients with different male breast diseases, diagnosed at our institution between January 1990 and July 2001, were retrospectively evaluated. The history, physical examination, mammographic and ultrasonographic findings were analyzed. Results: The spectrum of the disease in 236 male patients were gynecomastia (n=206), primary breast carcinoma (n=14), fat necrosis (n=5), lipoma (n=3), subareolar abscess (n=2), epidermal inclusion cyst (n=1), sebaceous cyst (n=1), hematoma (n=1), myeloma (n=1), and metastatic carcinoma (n=2). The distribution of patterns of gynecomastia were; 34% (n=71) nodular, 35% (n=73) dendritic and 31% (n=62) diffuse glandular. Gynecomastia was unilateral in 55% (n=113) and bilateral in 45% (n=93) of the patients. Male breast cancer presented as a mass without microcalcifications in 86% (n=12) and with microcalcifications in 7% (n=1) of patients. The mass was obscured by gynecomastia, partially in two, totally in one patient. The location of the mass was retroareolar in 46% (n=6) and eccentric to the nipple in 54% (n=7) of patients. On ultrasonography (US), the contours were well-circumscribed in 20% (n=3) and irregular in 80% (n=12) of the masses. Conclusion: Male breast has a wide spectrum of diseases, some of which have characteristic radiological appearances that can be correlated with their pathologic diagnosis. In the evaluation of the male breast, mammography and US are essential and should be performed along with physical examination

    The observed bimodal patterns of breast cancer incidence in the U.S. suggested that breast cancer may be viewed as more than one biological entity. We studied the factors potentially contributing to this phenomenon, specifically focusing on how disease heterogeneity could be linked to breast carcinogenesis mechanisms. Using empirical analyses and population-based biologically motivated modeling, age-specific patterns of incidence of ductal and lobular breast carcinomas from the SEER registry (1990-2003) were analyzed for heterogeneity and characteristics of carcinogenesis, stratified by race, stage, grade, and estrogen (ER)/progesterone (PR) receptor status. The heterogeneity of breast carcinoma age patterns decreased after stratification by grade, especially for grade I and III tumors. Stratification by ER/PR status further reduced the heterogeneity, especially for ER(+)/PR(-) and ER(-)/(-) tumors; however, the residual heterogeneity was still observed. The number of rate-limiting events of carcinogenesis and the latency of ductal and lobular carcinomas differed, decreasing from grade I to III, with poorly differentiated tumors associated with the least number of carcinogenesis stages and the shortest latency. Tumor grades play important role in bimodal incidence of breast carcinoma and have distinct mechanisms of carcinogenesis. Race and cancer subtype could play modifying role. ER/PR status contributes to the observed heterogeneity, but is subdominant to tumor grade. Further studies on sources of "remaining" heterogeneity of population with breast cancer (such as genetic/epigenetic characteristics) are necessary. The results of this study could suggest stratification rather than unification of breast cancer prevention strategies, risk assessment, and treatment.

    Preclinical and correlative studies suggest reduced breast cancer with higher lignan intake or blood levels. We conducted a pilot study of modulation of risk biomarkers for breast cancer in premenopausal women after administration of the plant lignan secoisolariciresinol given as the diglycoside (SDG). Eligibility criteria included regular menstrual cycles, no oral contraceptives, a greater than 3-fold increase in 5 year risk, and baseline Ki-67 ≥2% in areas of hyperplasia in breast tissue sampled by random periareolar fine needle aspiration (RPFNA) during the follicular phase of the menstrual cycle. SDG 50 mg daily was given for 12 months, followed by repeat RPFNA. The primary endpoint was change in Ki-67. Secondary endpoints included change in cytomorphology, mammographic breast density, serum bioavailable estradiol, and testosterone IGF-I and IGFBP-3, and plasma lignan levels. Forty-five of 49 eligible women completed the study with excellent compliance (median = 96%) and few serious side effects (4% grade 3). Median plasma enterolactone increased ~ 9-fold, and total lignans 16 fold. Thirty-six (80%) of the 45 evaluable subjects demonstrated a decrease in Ki-67, from a median of 4% (range 2–16.8 %) to 2% (range 0–15.2%) (p<0.001 by Wilcoxon signed rank test). A decrease from baseline in the proportion of women with atypical cytology (p=0.035) was also observed. Based on favorable risk biomarker modulation and lack of adverse events, we are initiating a randomized trial of SDG vs. placebo in premenopausal women. PMID:20724470

    Mammography of male breast account for less than 1% of mammographic examinations in most breast services. Due to the low incidence of breast cancer in men the significant majority of mammographic diagnosis reveals benign diseases, mostly gynecomastia. Therefore it is most important to identify features of benign conditions, such as gynecomastia, in order to reduce the number of unnecessary surgical biopsies performed in these patients, for the same reason suspicious lesions must be recognized as well. Indications for mammography in men include evaluation of palpable mass, recent onset of breast nipple-areolar skin changes or papillary discharge, and previous history of cancer.

    The aim of this study is to evaluate the fibrocystic breast disease rates and its association with different clinical, endocrine and metabolic parameters between main polycystic ovary syndrome (PCOS) phenotypes. One hundred thirty two consecutive women were included in the study. Body mass index, serum follicle-stimulating hormone, luteinizing hormone (LH), progesterone, estradiol, testosterone, dehydroepiandrosterone sulphate, fasting glucose, low density lipoprotein (LDL-C), total cholesterol, high density lipoprotein, insulin, insulin sensitivity and fibrocystic breast disease rates were compared among different phenotypes of PCOS. Group 1: Polycystic ovaries (PCO)-anovulation (n = 32), Group 2: Hyperandrogenemia (HA)-anovulation (n = 28), Group 3: HA-PCO (n = 29), Group 4: HA-PCO-anovulation (n = 43). There were statistically significant differences between the different phenotype groups in terms of waist-hip ratio (p = 0.006), serum LDL-C (p = 0.008), LH (p = 0.002), estradiol (p = 0.022), fasting glucose (p = 0.001), progesterone (p = 0.007), free testosterone levels (p fibrocystic breast disease rates. (p = 0.016). Higher free testosterone >3 pg/dl was protective for fibrocystic disease (RR = 0.316, 95:% CI 0.109-0.912, p = 0.033). Higher FG scores were more protective for fibrocystic disease (RR = 0.005, 95:% CI 0.001-0.042, p fibrocystic disease, while higher rates were observed in group 1 anovulatory-normoandrogenemic PCOS patients. Hyperandrogenemia is protective for fibrocystic diseases in PCOS.

    Fibrocystic changes (FCC) is the most common benign breast disease. The main pathophysiologic mechanism of FCC, excessive cell proliferation in response to monthly estrogen and progesterone changes. Regarding to antiproliferative of metformin, the aim of this study is the evaluation of the effect of metformin on FCC in women who were referred to gynecology clinics of ArakMETHODS:This study is a double blind placebo control randomized clinical trial. At the first among women who were referred to gynecology of Arak, 186 women with FCC between 18-40 years were selected. The women were randomly classified into three groups. The first group took metformin and the second group as placebo group took vitamin E and the third group did not take any drug during six months. All groups were compared in clinical symptoms based on visual analogue scale (VAS) and the sonographic data also were recorded and compared. Data analysis was performed by unilateral variance, student t and Chi-square. The three groups were not different in aspect of mean of the cysts number, cyst size, tenderness and discharge from breast before the intervention, but after the intervention, there was a significant decrease in metformin group (p value < 0.001) based on variance analysis test. There was not a meaningful difference of pain and the location of cysts between the groups after the intervention. The present study showed that metformin is effective in treatment of FCC and decreasing of clinical symptoms and imaging items.

    Women with atypical hyperplasia (AH) on a benign breast biopsy specimen are at increased risk for the development of breast cancer. However, the relation between the type and extent of AH (atypical ductal hyperplasia [ADH] vs atypical lobular hyperplasia [ALH]) and the magnitude of the breast cancer risk is not well defined. A nested case-control study of benign breast disease and breast cancer risk was conducted. Women with breast cancer and prior benign breast biopsy findings (488 cases) were matched to women with prior benign breast biopsy findings who were free from breast cancer (1907 controls). Benign breast biopsy slides were reviewed and categorized as nonproliferative, proliferative without atypia, or AH (ADH or ALH). The number of foci of AH was also recorded. Among women with ADH, the interrelation between the extent of atypia and breast cancer risk was not significant (odds ratio [OR] for 1 or 2 foci, 3.5; 95% confidence interval [CI], 2.2-5.6; OR for ≥3 foci, 2.7; 95% CI, 1.4-5.1; P = .41). Similarly, although the risk with ALH was higher for those with ≥3 foci than for those with breast cancer risk. The lack of a significant dose-response relation between the extent and type of atypia and breast cancer risk suggests that it would be premature to use the extent of atypia to influence management decisions for women with ADH or ALH. © 2015 American Cancer Society.

    Full Text Available Although the aetiology of Mondor′s disease remains unclear, the most commonly cited cause is trauma of some sort. Although surgical trauma has frequently been quoted, reports that specifically implicate aesthetic breast surgery are unusual in the literature. In this article, the authors report a case of superficial thrombophlebitis of the anterolateral chest wall secondary to breast augmentation surgery in a woman, five months after the procedure. The authors performed an analysis of the disease′s main etiologic components and preponderant clinical aspects, and determined all appropriate therapeutic measures.

    The malignancy risk, risk of being high-risk lesions after benign results on ultrasonography-guided 14-gauge core needle biopsies (US-CNBs), and their characteristics in breast lesions of 20 mm or greater were investigated. Eight hundred forty-seven breast lesions with benign results on US-CNB were classified as benign, high risk, and malignant through excision and clinical follow-up. The risks of being malignant or high risk were analyzed in all lesions, lesions 20 to 29 mm, and lesions 30 mm or greater. Their clinicopathological characteristics were evaluated. Of 847, 18 (2.1%) were malignant, 53 (6.3%) were high-risk lesions, and 776 (91.6%) were benign. Of 18 malignancies, 6 (33.3%) were malignant phyllodes tumors and 12 (66.7%) were carcinomas. In benign lesions 20 to 29 mm, risks of being malignant or high risk were 1.6% (9 of 566) and 4.4% (25 of 566). In 281 lesions 30 mm or greater, the risks of being malignant or high risk were 3.2% and 10%. The risk of being high risk in lesions 30 mm or greater was 10%, significantly higher than 4.4% of lesions 20 to 29 mm (P = 0.002). Excision can be considered in lesions measuring 20 mm or larger because of the 2.1% malignancy risk and the 6.3% risk of being high-risk lesions despite benign results on US-CNB. Excision should be considered in lesions measuring 30 mm or larger because of the 3.2% malignancy risk and the 10% risk of being high-risk lesions.

    As breast cancer tissues are stiffer than normal tissues, shear wave elastography (SWE) can locally quantify tissue stiffness and provide histological information. Moreover, tissue stiffness can be observed on three-dimensional (3D) colour-coded elasticity maps. Our objective was to evaluate the diagnostic performances of quantitative features in differentiating breast masses by two-dimensional (2D) and 3D SWE. Two hundred ten consecutive women with 210 breast masses were examined with B-mode ultrasound (US) and SWE. Quantitative features of 3D and 2D SWE were assessed, including elastic modulus standard deviation (E SD E ) measured on SWE mode images and E SD U measured on B-mode images, as well as maximum elasticity (E max ). Adding quantitative features to B-mode US improved the diagnostic performance (p < 0.05) and reduced false-positive biopsies (p < 0.0001). The area under the receiver operating characteristic curve (AUC) of 3D SWE was similar to that of 2D SWE for E SD E (p = 0.026) and E SD U (p = 0.159) but inferior to that of 2D SWE for E max (p = 0.002). Compared with E SD U , E SD E showed a higher AUC on 2D (p = 0.0038) and 3D SWE (p = 0.0057). Our study indicates that quantitative features of 3D and 2D SWE can significantly improve the diagnostic performance of B-mode US, especially 3D SWE E SD E , which shows considerable clinical value.

    To explore the feasibility of preoperative planning for treatment of benign mandibular lesions (BML) using digital technologies such as three-dimensional (3D) reconstruction, measurement, visualization as well as image contrast and design of neural positioning protection template (NPPT) in combination with 3D printing technology in the BML diagnosis and treatment. The 3D models of BML and inferior alveolar nerves (IAN) of 10 BML patients were reconstructed based on their digital imaging and communications in medicine (DICOM) data using MIMICS16.0 software. The models were used to visualize lesions and nerve contrast measurement and guide design of personalized NPPT and osteotomy after operation modality was determined in order to achieve accurate, minimally invasive operation with shortened intraoperative time. Intraoperative NPPT application could accurately locate lesions and their scope and assist osteotomy. The measurement results were consistent with those of preoperative reconstruction and measurement. The BML were curetted completely without damage IAN. The 10 BML patients had no numbness and other discomforts in the lower lip and mandibular teeth after operation. The digital diagnosis and treatment technology is an effective method for functional treatment of BML patients and its application could achieve personalized, minimally invasive and precise treatment and save intraoperation time.

    Among the rare anomalies of the breast development, polythelia is the most common, between 1% and 5% of women and men present supernumerary nipples. Polymastia, usually presenting as ectopic breast tissue without areola-nipple complex, is seen mostly along the milk line, extending from the axilla to the pubic region. Ectopic breast tissue is functionally analogous to mammary gland and it is subjected to the same alterations and diseases, whether benign or malignant, that affect normal breast tissue. We report the case of a 21 years-old female evaluated by the medical staff after founding a solid nodular mass by suspect axillary lymphadenopathy. Differential diagnosis with lymphoma is the major problem in these cases. The mass was removed and the intraoperative histological examination showed fibroadenoma in axillary supernumerary breast. Presence of ectopic breast tissue is a rare condition; development of benign mass or malignant degeneration is possible, but it is very unusual. In case of polymastia diagnosis is simple; in case of isolated nodule, without local inflammation or infection, there are greater difficulties. Ultrasonography is diagnostic in case of breast fibroadenoma, but it might be inadequate in ectopic localizations owing to the shortage of mammary tissue around the mass. Preoperative diagnosis is important to plan an adequate surgical treatment; lumpectomy is indicated in case of benign tissue; in case of malignancy, therapy is based on the standard treatment used for breast cancer (surgery, chemotherapy and radiation therapy).

    Three patients developed bilateral breast cancer at 10 to 24 years after mantle irradiation for locally or systemically advanced Hodgkin's disease (HD). Four of the six cancers in the three patients were detected only by mammography. Pathologically, five of the cancers were intraductal carcinomas (four with an invasive component) with one being a lobular carcinoma. Five of the six lesions were Stage I pathologically without evidence of axillary nodal involvement. It is recommended that female patients with Hodgkin's disease who have received mantle irradiation as part of the therapy for their Hodgkin's disease and who are observed for 10 or more years after completion of mantle irradiation be considered at risk for the development of breast cancer. Such patients should be monitored appropriately by routine bilateral mammograms to increase the early detection of early stage lesions.

    Although mammography is indisputably the best diagnostic method for detecting breast abnormalities, there are other techniques, such as ultrasonography and magnetic resonance, which are increasingly widely employed as additional indispensable aids. The present work compares mammography, ultrasound and magnetic resonance images of normal breast and of the major pathologies that can be observed in breast, including sclerosing adenosis, giant fibroadenoma, multifocal carcinoma, fibrocystic breast disease, infiltrating duct carcinoma, colloid carcinoma, radical scar, abscess and breast prosthesis.

    2001-07-01

    A new neural network technology was developed for improving the benign/malignant diagnosis of breast cancer using mammogram findings. A new paradigm, Adaptive Boosting (AB), uses a markedly different theory in solutioning Computational Intelligence (CI) problems. AB, a new machine learning paradigm, focuses on finding weak learning algorithm(s) that initially need to provide slightly better than random performance (i.e., approximately 55%) when processing a mammogram training set. Then, by successive development of additional architectures (using the mammogram training set), the adaptive boosting process improves the performance of the basic Evolutionary Programming derived neural network architectures. The results of these several EP-derived hybrid architectures are then intelligently combined and tested using a similar validation mammogram data set. Optimization focused on improving specificity and positive predictive value at very high sensitivities, where an analysis of the performance of the hybrid would be most meaningful. Using the DUKE mammogram database of 500 biopsy proven samples, on average this hybrid was able to achieve (under statistical 5-fold cross-validation) a specificity of 48.3% and a positive predictive value (PPV) of 51.8% while maintaining 100% sensitivity. At 97% sensitivity, a specificity of 56.6% and a PPV of 55.8% were obtained.

    The aim of this study was to assess the performance of shear wave elastography combined with BI-RADS classification of greyscale ultrasound images for benign/malignant differentiation in a large group of patients. One hundred and seventy-five consecutive patients with solid breast masses on routine ultrasonography undergoing percutaneous biopsy had the greyscale findings classified according to the American College of Radiology BI-RADS. The mean elasticity values from four shear wave images were obtained. For mean elasticity vs greyscale BI-RADS, the performance results against histology were sensitivity: 95% vs 95%, specificity: 77% vs 69%, Positive Predictive Value (PPV): 88% vs 84%, Negative Predictive Value (NPV): 90% vs 91%, and accuracy: 89% vs 86% (all P>0.05). The results for the combination (positive result from either modality counted as malignant) were sensitivity 100%, specificity 61%, PPV 82%, NPV 100%, and accuracy 86%. The combination of BI-RADS greyscale and shear wave elastography yielded superior sensitivity to BI-RADS alone (P=0.03) or shear wave alone (P=0.03). The NPV was superior in combination compared with either alone (BI-RADS P=0.01 and shear wave P=0.02). Together, BI-RADS assessment of greyscale ultrasound images and shear wave ultrasound elastography are extremely sensitive for detection of malignancy.

The patient usually are for routine checkup to nonspecific symptoms with few showing specific signs and symptoms. In this study, an attempt has been made to understand the role of ultrasound in diagnosing benign lesions with a drawback focused on early malignant lesion. Also, the differentiation of solid and cystic lesions can reduce biopsy. MATERIALS AND METHODS This study was done retrospectively evaluating 131 consecutive patients. The ultrasound study included evaluation of mainly female patients with few male cases. RESULTS Most common lesions were benign lesions. Among these benign lesions, fibroadenomas and fibrocystic disease were the commonest. However, there were no early malignant lesion seen in this study. CONCLUSION Breast ultrasound is choice of investigation in benign breast diseases. Also, such lesions can be easily followed up at primary level. However, there is a limited role in detecting early malignant lesions, which will require additional workup at a higher level especially in high-risk groups.

    In these two decades breast cancer is one of the leading cause of death among women. In breast cancer research, Mammographic Image is being assessed as a potential tool for detecting breast disease and investigating response to chemotherapy. In first stage of breast disease discovery, the density measurement of the breast in mammographic images provides very useful information. Because of the importance of the role of mammographic images the need for accurate and robust automated image enhancement techniques is becoming clear. Mammographic images have some disadvantages such as, the high dependence of contrast upon the way the image is acquired, weak distinction in splitting cyst from tumor, intensity non uniformity, the existence of noise, etc. These limitations make problem to detect the typical signs such as masses and microcalcifications. For this reason, denoising and enhancing the quality of mammographic images is very important. The method which is used in this paper is in spatial domain which its input includes high, intermediate and even very low contrast mammographic images based on specialist physician's view, while its output is processed images that show the input images with higher quality, more contrast and more details. In this research, 38 mammographic images have been used. The result of purposed method shows details of abnormal zones and the areas with defects so that specialist could explore these zones more accurately and it could be deemed as an index for cancer diagnosis. In this study, mammographic images are initially converted into digital images and then to increase spatial resolution power, their noise is reduced and consequently their contrast is improved. The results demonstrate effectiveness and efficiency of the proposed methods. (authors)

    The risk of female breast cancer in association with radiation exposure is well established, on the basis of follow-up studies of the atomic-bomb survivors and other exposed populations. This association is especially strong for women exposed before age 20 yr and appears to be much weaker among women exposed after age 40 yr. In this study, breast-tissue autopsy samples from high-dose and low-dose individuals in the Radiation Effects Research Foundation Life Span Study sample were examined in detail to determine whether nonproliferative or proliferative breast lesions are associated with radiation exposure. The results suggest that proliferative disease in general and atypical hyperplasia in particular are associated with radiation exposure and that the risk is strongest for subjects who were ages 40-49 yr at the time of the bombings. It is hypothesized that this finding may be related to the age dependence of radiation-induced breast cancer, in the sense that potential cancers reflecting early-stage changes induced at these ages by radiation exposure may receive too little hormonal promotion to progress to frank cancers.
