    Secretory carcinoma of the breast is a rare tumor initially described in children but occurring equally in adult population. This unusual breast cancer subtype has a generally favorable prognosis, although several cases have been described in adults with increased aggressiveness and a risk of metastases. However, surgery is still considered the most appropriate treatment for this pathology. We describe the case of a 50 -year-old woman who has undergone a breast conservative surgery for a little tumor, preoperatively diagnosticated by a fine needle aspiration biopsy (FNAB) as a well differentiated infiltrating carcinoma.

    The thyroid gland is an uncommon site for metastasis to develop and thus metastases arising from breast cancer are rarely observed. In the present study, we describe a case of a 45-year-old female with a three-year history of breast cancer who presented with a thyroid mass that was diagnosed as metastatic breast carcinoma by histopathological analysis of the subtotal thyroidectomy specimen. To ascertain the diagnosis of metastatic breast cancer, we evaluated two types of markers; those that p...

    Full Text Available Metastasis to breast from nonmammary malignancy is only about 1.3–2.7%. A few cases of squamous cell carcinoma of esophagus and adenocarcinoma of stomach metastasizing to breast have been reported, but this is probably the first report of breast metastasis from esophagogastric junction (EGJ cancer in the English literature. Herein we report a case of a 32-year-old patient diagnosed as adenocarcinoma of gastroesophageal junction, presenting with left breast metastasis two years after treatment. Given unusual site of metastasis in a follow-up case of EGJ cancer, not only it is challenging to differentiate it from primary carcinoma of breast but also it is important from treatment point of view. In our case, clinical data, radiology, histopathology, and immunohistochemistry (IHC led us to reach the diagnosis.

  6. Imaging screening of breast cancer: primary results in 5307 cases

    International Nuclear Information System (INIS)

    Objective: To discuss the values of three screening methods for the detection of early breast cancer, and to analyze the features of the screening cancer. Methods: The first screening of breast cancer were performed in 5307 women who aged from 20 to 76 years with median age of 49 years. The three screening methods included physical examination with ultrasound and mammography, physical examination with mammography and mammography only. The rate of recall, biopsy, cancer detection of three methods were analyzed and the mammographic findings were reviewed. Chi-square test or Fisher's exact test were used for the statistics. Results: The recall rates were 4.90% (49/1001), 6.90% (166/2407) and 4. 48% (85/1899) in three methods respectively, the biopsy rates were 1.60% (16/1001), 1.04% (25/2407) and 0.63% (12/1899), the cancer detection rates were 0.50% (5/1001), 0.17% (4/2407) and 0 (0/1899). There were statistical differences among the three groups (χ2=12.99,6.264,8.764, P<0.05). Physical examination with ultrasound and mammography had the highest cancer detection rate, ten breast cancers were detected and 8 were early stage breast cancer. Of seven cancers detected by mammography, only two were found by ultrasound. A cluster of calcifications were found in 2 cases, linear calcifications in 2 cases. One case presented as a asymmetric density, one as a asymmetric density with calcifications, one as multiple nodules with a cluster of calcifications. Two breast cancers presented as asymmetric density were missed on mammography and diagnosed correctly after retrospective review. Conclusion: Physical examination with ultrasound and mammography is the best method for breast cancer screening. The breast cancer can be detected by mammography earlier than other methods.

  7. Case-control study of fetal microchimerism and breast cancer.

    Directory of Open Access Journals (Sweden)

    Vijayakrishna K Gadi

    Full Text Available BACKGROUND: Prior pregnancy is known to protect against development of breast cancer. Recent studies have demonstrated that pregnancy has the capacity to establish small numbers of immunologically active fetal-derived cells in the mother, a phenomenon known as fetal microchimerism (FMc. We asked whether presence of FMc, routinely acquired during pregnancy, is a protective factor for breast cancer. METHODOLOGY/PRINCIPAL FINDINGS: DNA extracts from peripheral blood specimens were obtained from a population-based case-control study of risk factors for breast cancer in women 21 to 45 years old. Specimens were tested with quantitative PCR for presence and concentrations of male DNA presumed to derive from prior pregnancies with a male fetus. Odds ratios (OR and 95% confidence intervals (CI were estimated with consideration of multiple established reproductive and environmental risk factors for breast cancer. FMc results were generated on 99 parous women, 54 with primary invasive breast cancer and 45 general population controls. FMc prevalence was 56% (25/45 and 26% (14/54 in controls and cases, respectively. Women harboring FMc were less likely to have had breast cancer (OR = 0.29, 95% CI 0.11-0.83; p = 0.02, adjusting for age, number of children, birth of a son, history of miscarriage, and total DNA tested. In addition, FMc concentrations were higher in controls versus cases (p = 0.01. Median concentrations were 2 (0-78 and 0 (0-374 fetal genomes/10(6 maternal genomes in controls and cases, respectively. CONCLUSIONS: Results suggest that the enigma of why some parous women are not afforded protection from breast cancer by pregnancy might in part be explained by differences in FMc. Mechanistic studies of FMc-derived protection against breast cancer are warranted.

    Full Text Available Abstract Introduction The incidence of tuberculosis is rising worldwide and rare manifestations of the past are seen more often nowadays. Mammary tuberculosis is a rare clinical entity, often mimicking breast cancer or abscesses of benign or malignant origin. Clinical awareness is necessary during diagnostic work-up for establishing the correct diagnosis and treatment. Case presentation We present a case of breast tuberculosis diagnosed in a 73 year old woman at our institution. The patient presented with a palpable mass of the right breast with clinical, laboratory and mammographic findings indicative of breast carcinoma. The patient underwent lumpectomy and sentinel lymph node biopsy. Frozen section of the tumor and the sentinel node revealed "granulomatous inflammation", while gross examination confirmed the diagnosis of tuberculous mastitis. The patient received anti-tuberculosis therapy for six months with no side effects or any further complications. Conclusion Breast tuberculosis is an obscure disease often mistaken for carcinoma or pyogenic abscess of the breast, especially if well-defined clinical features are absent. A high index of suspicion is required because the disease can usually be treated conservatively with current antituberculous modalities while surgical intervention is reserved for rare cases only.

    2013-01-01

    Summary Background Significant controversy exists in the literature regarding the role of pregnancy in the prognosis of breast cancer. We designed a matched case-case study, matching pregnancy-associated breast cancer (PABC) cases with breast cancer cases for stage, age, and year of diagnosis. Patients and Methods 39 consecutive cases of PABC were matched with 39 premenopausal cases of breast cancer. Univariate and multivariate survival analyses followed by adjustment for stage, grade, estrogen receptor status, and age at diagnosis, were performed. Results Regarding overall survival (OS), univariate analysis pointed to longer OS in non-PABC cases vs. PABC cases. Accordingly, a more advanced stage predicted shorter survival. In the multivariate analysis, the independent aggravating effect mediated by pregnancy persisted. Interestingly, a post hoc nested analysis within PABC cases indicated that the 3rd trimester pointed to shorter OS. The aforementioned results on OS were also replicated during the examination of relapse-free survival. Conclusion Implementing a matched case-case design, the present study points to pregnancy as a poor prognostic factor for breast cancer. PMID:24415971

    Breast metastasis from gastric carcinoma is rare. We present a case of right breast mass with microcalcification in which the diagnosis of poorly differentiated adenocarcinoma from the stomach was made after a biopsy. Pleomorphic microcalcification was noted in the ill-defined breast mass, which is a rare feature in breast metastasis. Since breast metastasis usually signifies advanced metastatic disease, differentiating primary breast cancer from metastasis is important for appropriate treatment. PMID:23091550

    Conclusion: Although metastasis of breast cancer to the genital organs is an uncommon event, breast carcinoma is still considered the second source of extragenital malignant metastasis to the uterus. Overall, the most popular sites for metastasis of breast carcinoma to the female reproductive system include the ovaries and the uterine cervix. The uterine corpus is the least common site involved. In this regard metastasis to a uterine leiomyoma is a rare event.

    OBJECTIVE Discussion of diagnosis, treatment and prognosis of nonpalpable TO breast cancer.METHODS Between 1978 and 1997, 9,980 female patients with operable breast cancer were treated surgically, of which 276 were determined to have TO breast cancer. Most TO breast cancers could be detected promptly with careful examination of presenting symptoms, such as nipple discharge, local thickening of the breast, nipple erosion, nipple retraction and postmenopausal mastalgia, while 12 cases were detected by routine mammography of the contralateral breast.RESULTS All patients were treated surgically and their tissue subjected to histopathological examination. Most cases (73.0%) were noninvasive or early invasive carcinoma. Axillary lymph nodes metastases were found in 7.69% of 234 mastectomy cases.CONCLUSION The survival rate was significantly increased if the tumor was in an early stage. The 5-, 10-, 15-years survival rates were 98.1%,94.6% and 90.3%, respectively.

    Gastric metastasis is rare but it can be the initial symptom of cancer. The second leading cause of this type of metastasis is breast cancer. A lack of clinical signs and nonspecific side effects of the treatment of primary tumors can lead to the misdiagnosis of metastatic gastric cancer. Upper gastrointestinal endoscopy with biopsy and immunohistochemistry should be used for diagnosis. Treatment is palliative; it includes chemo, endocrine, and radiation therapies. Four patients with breast cancer and gastric metastasis were identified. All the patients tested positive for estrogen and progesterone receptors, and received chemotherapy and hormone therapy. One patient underwent surgery and two received radiation therapy. Patients with breast cancer and gastrointestinal symptoms should be investigated for gastric metastasis, given its morbidity and negative impact on quality of life.

  3. A case control study of risk factors associated with female breast cancer

    International Nuclear Information System (INIS)

    To find the association of various risk factors with breast cancer. Study Design: It was a case-control study. Place and Duration of Study: The study was carried out in NORI Hospital Islamabad and Combined Military Hospital Rawalpindi between August, 2013 and February, 2014. Material and Methods: Two hundred breast cancer patients and 200 control subjects were inducted. A short approved and planned questionnaire was used to collect data regarding basic demographic, menstrual and reproductive characteristics of participating females. Cases and controls were then interviewed after taking written consent. Results: Breast cancer patients and control subjects did not differ regarding age (p = 0.15), early menarche (OR for menarche at <13 years vs. ?13=1.3, 95% CI = 0.84 - 2.02), and history of breast cancer in 1st degree relatives did not increase breast cancer risk (OR = 1.0, 95% CI = 0.57 - 1.74). Nulliparous women had significantly higher risk than parous women (OR = 2.43, 95% CI = 1.22 - 4.84) and women with late menopause compared to women with early onset of menopause were also at higher risk for breast cancer (OR for menopause at ? 50 vs. < 50 = 5.16, 95% CI = 2.59 - 10.29). Conclusion: Nulliparity and menopausal age of more than 50 years was associated with increased breast cancer risk. Breast feeding and age less than 25 years at first live birth was not protective against breast cancer. (author)

    A traumatic neuroma is a tangle of neural fibers and connective tissues which develop at the end of a proximal nerve stump following the nerve injury. The incidence of traumatic neuroma after breast cancer surgery is extremely low, and so far, there are only 11 cases being reported in literature. We present sonographic and pathologic features of a traumatic neuroma that mimics the recurrent breast carcinoma identified on follow-up ultrasound examinations after breast cancer surgery.

    Objective: To study the biological characteristics, the therapeutic procedure and the prognosis of male breast cancer.Methods: 34 patients with male breast cancer were retrospectively analyzed, who were diagnosed and treated in the First Hospital of Jilin University between 1980 and March 2005. Results: Clinical TNM stage of the patients were stage Ⅰ, 6patients, stage Ⅱ, 24 patients and stage Ⅲ, 4 patients. Positive lymph nodes were found in 35.3% of the patients. All these patients received modified radical mastectomy. The 5-year survival rate was 65.3%. Postoperation recurrence rate was 11.8%.Conclusions: Patients with male breast cancer should receive surgical treatment, assisted with adjuvant treatment, such as radiotherapy, chemotherapy, endocrine therapy and so on. TNM stage and expression of hormone receptor may be the main factors affecting the prognosis.

    An 84-year-old woman was examined for an enlargement of an induration in the left breast. A ventriculoperitoneal shunt had been placed for postoperative normal pressure hydrocephalus of a cerebral hemorrhage, and it had penetrated the mass according to the computed tomography findings. Breast cancer was diagnosed after a close examination; however, close observation was selected because her family rejected treatment. She developed somnolence 7 months after the initial examination, and ventricular dilatation and expansion of the low-density region around the ventricle were noted on computed tomography, suggesting that the enlarged tumor had excluded the shunt and caused obstruction. The growth of breast carcinoma involving a shunt tube can be the cause of obstruction of a ventriculoperitoneal shunt. Our findings suggest that a breast lesion should be evaluated at both pre- and postoperation. PMID:26943684

    The liver is one of the commonest sites of metastatic involvement in breast cancer, usually evident as focal lesions on imaging tests. Rarely, the pattern of metastatic spread is so diffuse that it remains radiologically occult. Such patients usually present with signs of hepatic insufficiency without any focal lesions on liver imaging. In such cases, liver biopsy is required to make a definitive diagnosis. We report a case of a 56-year-old postmenopausal woman with metastatic breast cancer who presented with subacute progressive liver failure. Repeated imaging of the liver was normal or non-descript. Liver biopsy finally established the diagnosis of intrasinusoidal metastases from breast cancer.

    Full Text Available Abstract Background Tobacco smoke exposure may be associated with increased breast cancer risk, although the evidence supporting the association is inconclusive. We conducted a case-control study in Delaware, incorporating detailed exposure assessment for active and secondhand smoke at home and in the workplace. Methods Primary invasive breast cancer cases diagnosed among female Delaware residents, ages 40–79, in 2000–2002 were identified through the Delaware cancer registry (n = 287. Delaware drivers license and Health Care Finance Administration records were used to select age frequency-matched controls for women Results A statistically significant increased risk of breast cancer was observed for ever having smoked cigarettes (odds ratio = 1.43, 95% confidence interval = 1.03–1.99. However, there was no evidence of a dose-response relationship between breast cancer risk and total years smoked, cigarettes per day, or pack-years. Neither residential nor workplace secondhand smoke exposure was associated with breast cancer. Recalculations of active smoking risks using a purely unexposed reference group of women who were not exposed to active or secondhand smoking did not indicate increased risks of breast cancer. Conclusion These findings do not support an association between smoking and breast cancer.

    We report a case of a 59-year-old woman who was forced to undergo mastectomy of the right breast (Rt Bt) plus axillary lymph node (Ax) dissection for right breast cancer at another hospital. The pathological diagnosis was invasive ductal carcinoma( scirrhou[s sci], pT2N2M0, Stage IIIA, estrogen recepto[r ER[]+], progesterone recepto[r PgR[]+], human epidermal growth factor receptor-2[HER2][2+]). Although no recurrence was observed after postoperative adjuvant chemotherapy and endocrine therapy, skin metastasis on the left back and pleuritis carcinomatosa were detected at our hospital 9 years and 6 months after the operation. Thereafter, bone metastasis, contralateral lymph node metastasis, and frequent occurrence of hepatic metastasis were sequentially detected. The patient was treated with chemotherapy (a total of 4 regimens) and endocrine therapy in addition to radiation therapy for lymph node metastasis over a period of approximately 2 years and 3 months; however, disease control was poor. Therefore, combined chemotherapy with paclitaxel and bevacizumab was initiated from February 2012. Soon after the initiation of combination therapy, the serum carcinoembryonic antigen (CEA) level gradually reduced and computed tomography (CT) revealed that the multiple-organ metastases had remarkably reduced in size. The response was classified as a clinical partial response (cPR). Although adverse events such as peripheral neuropathy, nose bleeding, and high blood pressure were observed, these were all of lesser that Grade 2 severity. The efficacy of chemotherapy was noted for 11 months. PMID:24394122

  1. Population-based case-control study of breast cancer in Albania

    Full Text Available In Albania, breast cancer is an important cause of death among women, with increasing incidence from 65 cases in 1970, to 400 cases in 2007. This is the first study concerning breast cancer risk factors in Albania. We used a population-based case-control study of 948 women with breast cancer compared with 1019 controls recruited from other hospitals through random selection. Early age at menarche was found to be a significantly strong risk factor during the pre- and postmenopausal groups with OR 10.04 and 12.1, respectively. In addition, nulliparity is associated with higher risk while abortion did not indicate any influence in the multivariate model. The findings from this study have shown that reproductive and menstrual variables are significant predictors of breast cancer risk in Albanian women, as seen in studies of other western countries.

  2. Inheritance of proliferative breast disease in breast cancer kindreds

    International Nuclear Information System (INIS)

    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

  3. Urinary strontium and the risk of breast cancer: A case-control study in Guangzhou, China

    International Nuclear Information System (INIS)

    Strontium has been widely used in industries like electronic and pharmacy. It has a carcinogenic potential, however, and no study has been conducted to evaluate its effects on cancer risk. The aim of this study was to explore the possible association between strontium and breast cancer risk in a case-control study including 240 incident invasive breast cancer patients and 246 age-matched controls. We measured the urinary concentrations of strontium by inductively coupled plasma mass spectrometry, and conducted face-to-face interviews to obtain information on potential breast cancer risk factors. Multivariable analysis was used to estimate the association. Creatinine-adjusted levels [median (25th, 75th) μg/g] of strontium were 155.59 (99.05, 230.70) in the breast cancer patients and 119.62 (81.97, 163.76) in the controls. Women in the highest tertile of strontium showed 124% increased risk of breast cancer, when compared with those in the lowest tertile after adjustment for the potential risk factors [OR (95% CI): 2.24 (1.42–3.81)]. This association was particularly strong for HER2 positive breast cancer [OR (95% CI): 10.92 (3.53–33.77)], and only occurred among premenopausal women. These results suggest a potential role of strontium in the development of breast cancer and urge further studies on the environmental contamination and the physiological and pathological mechanisms of strontium.

    Full Text Available Abstract Background Breast cancer is the most common form of malignancy affecting women worldwide. It is also the leading cancer in females in Cyprus, with approximately 400 new cases diagnosed annually. It is well recognized that genetic variation as well as environmental factors modulate breast cancer risk. The main aim of this study was to assess the strength of associations between recognized risk factors and breast cancer among Cypriot women. This is the first epidemiological investigation on risk factors of breast cancer among the Cypriot female population. Methods We carried out a case-control study, involving 1,109 breast cancer patients and a group of 1,177 controls who were recruited while participating in the National screening programme for breast cancer. Information on demographic characteristics and potential risk factors were collected from both groups during a standardized interview. Logistic regression analysis was used to assess the strength of the association between each risk factor and breast cancer risk, before and after adjusting for the possible confounding effect of other factors. Results In multivariable models, family history of breast cancer (OR 1.64, 95% CI 1.23, 2.19 was the strongest predictor of breast cancer risk in the Cypriot population. Late menarche (OR 0.64, 95% CI 0.45, 0.92 among women reaching menarche after the age of 15 vs. before the age of 12 and breastfeeding (OR 0.74, 95% CI 0.59, 0.92 exhibited a strong protective effect. In the case of breastfeeding, the observed effect appeared stronger than the effect of pregnancy alone. Surprisingly, we also observed an inverse association between hormone replacement therapy (HRT although this may be a product of the retrospective nature of this study. Conclusion Overall the findings of our study corroborate with the results of previous investigations on descriptive epidemiology of risk factors for breast cancer. This investigation provides important background

    We investigated the relationship between methylxanthine consumption and breast cancer using data from a case-control study which included 1,510 cases and 1,882 controls identified through a nation-wide breast cancer screening program. There was no evidence of a positive association between methylxanthine consumption and risk of breast cancer. In fact, there was some suggestion of a negative association, particularly in women diagnosed after age 50. In addition, there was no evidence of increased risk with past or recent methylxanthine consumption, or with the consumption of caffeine or specific beverages, most notably brewed or instant caffeinated coffee and tea.

  9. Four cases of radiation pneumonia after breast conservative therapy for breast cancer

    International Nuclear Information System (INIS)

    Between 1983 and 1996, a series of 240 patients with early stage breast cancer were treated with breast conservative treatment, and 201 patients of them all received irradiation at a dose of 46-60 Gy to the affected breast. Among the 201 patients who received breast irradiation, four (2.0%) patients experienced radiation pneumonia. These four patients with radiation pneumonia presented with coughing from 7 to 20 weeks after irradiation. Chest X-ray film revealed interstitial pneumonia in a lung field where coincided with the irradiated field in them. Three out of four patients demanded steroids, but all patients got well within 4 months. Radiation pneumonia following conservative surgery and radiotherapy for breast cancer is an infrequent complication, but attention should be paid to radiation pneumonia if the patient suffers from persistent coughing after radiotherapy.

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

    2009-01-01

    @@ Breast cancer is one of the most commonly seen malignant tumors in the female population, and it ranks the first in the incidence of malignancies among women. The skeleton is a common metastatic site for advanced breast cancer and is where spinal metastasis is most frequently seen. The incidence rate of spinal metastasis in descending order is as follows: thoracic vertebrae, lumbar vertebrae, sacrococcy-geal vertebrae and cervical vertebrae. Although osseous metastasis of breast cancer is very common, cases with metastasis to all vertebral bodies is currently very rare. The diagnostic method of osseous metastasis of breast cancer typically includes radiograph, CT and MRI. Ordinary radiograph has a high specificity but a low sensitivity, so total vertebral body metastases can only be detected when the extent of osteoclasia exceeds 50%. Some diagnostic shortcomings remain, although the sensitivity of CT and MRI has been greatly improved compared to the radiograph. At present, the most advanced synchronous PET-CT visualization can presumably raise the sensitivity and specificity in the diagnosis of breast cancer, based on the features of 18F-FDG imaging, and combined with morphologic change and precise localization. The following case report is in regard to a patient with total vertebral body metastasis from breast cancer detected by PET-CT.

    A panel of Japanese and American pathologists reviewed existing histologic material used to study breast cancer risk among the A-bomb survivors in Hiroshima and Nagasaki, a population in which incidence studies have found a strong relationship between breast cancer risk and radiation dose. The primary charge to the panel was to define a body of confirmed cases in the Life Span Study sample of the Radiation Effects Research Foundation that would require little or no review for inclusion in future studies of breast cancer incidence. Broad agreement on histologic type was reached for 298 of 300 confirmed cases. The distribution of histologic types was, overall, similar to that seen in other studies of breast cancer in Japanese women, and did not appear to depend on dose; thus radiation-induced breast cancer appeared to be no different histologically from other breast cancer. Also, no evidence was found of variation in histologic type by city, age at exposure, age at diagnosis, or calendar time. PMID:6331630

    Full Text Available Background: Breast cancer is one of the most prevalent cancers among women and features increasing trends of incidence rates. Worldwide, yearly about 1.67 million of new cases and 522,000 of deaths from breast cancer are registered. The aim of this study was to determine the risk factors of breast cancer in women and to identify high risk groups. Methods: In a case-control study, 170 women with breast cancer who were registered in cancer registration system from 2011 to 2015 at Dezful City, Iran, were compared with 170 healthy women with confirmation of mammography. After age matching of groups, the needed information about risk factors and demographic information including information, educational level, marital status, family history of breast cancer, age at menarche, parity, oral contraceptive use, age at first pregnancy, menopausal status, and age at menopause, breastfeeding, stress, abortion, alcohol use and smoking, hormone therapy and physical activity was collected by a questionnaire. The analysis of collected data was performed by using odds ratio and logistic regression model and SPSS software, version 16 (SPSS, Inc., Chicago, IL, USA. The statistical significance was set at a two-sided p-value of %5. Results: The results of this study showed that, women with the family history [OR: 6.78 (95% CI: 2.15-21.41] and women with the stress history [OR: 4.86 (95% CI: 2.46-9.59] had higher risk of breast canser, while women with the history of having physical activity at least once a week [OR: 0.29 (95% CI: 0.13-0.65] and women with the history breast feeding for 3 to 4 years [OR: 0.36 (95% CI: 0.16-0.81] had lower risk of breast cancer. Conclusion: It is recommended that the mentioned risk factors and protective factors be considered in first and second level (screening of preventive programs.

    We reported a case of port site metastasis in a 57-year-old patient who underwent video-assisted thoracic surgery (VATS) resection of pulmonary metastasis from breast cancer. Port site metastasis after VATS is very rare in patients with breast cancer. However, when suspicious lesions are detected near the port site in patients who have undergone VATS for pulmonary metastasis, port site metastasis should be considered in the differential diagnosis.

    Breast cancer is the most common malignancy in women worldwide. Tea has anticarcinogenic effects against breast cancer in experimental studies. However, epidemiologic evidence that tea protects against breast cancer has been inconsistent. A case-control study was conducted in Southeast China between 2004 and 2005. The incidence cases were 1009 female patients aged 20-87 years with histologically confirmed breast cancer. The 1009 age-matched controls were healthy women randomly recruited from breast disease clinics. Information on duration, frequency, quantity, preparation, type of tea consumption, diet and lifestyle were collected by face-to-face interview using a validated and reliable questionnaire. Conditional logistic regression analyses were used to estimate odds ratios (ORs) and associated 95% confidence intervals. Compared with non-tea drinkers, green tea drinkers tended to reside in urban, have better education and have higher consumption of coffee, alcohol, soy, vegetables and fruits. After adjusting established and potential confounders, green tea consumption was associated with a reduced risk of breast cancer. The ORs were 0.87 (0.73-1.04) in women consuming 1-249 g of dried green tea leaves per annum, 0.68 (0.54-0.86) for 250-499 g per annum, 0.59 (0.45-0.77) for 500-749 g per annum and 0.61 (0.48-0.78) for >or=750 g per annum, with a statistically significant test for trend (P consumption of green tea can protect against breast cancer. More research to closely examine the relationship between tea consumption and breast cancer risk is warranted. PMID:17183063

    Full Text Available Abstract Background Drinking water contaminated by wastewater is a potential source of exposure to mammary carcinogens and endocrine disrupting compounds from commercial products and excreted natural and pharmaceutical hormones. These contaminants are hypothesized to increase breast cancer risk. Cape Cod, Massachusetts, has a history of wastewater contamination in many, but not all, of its public water supplies; and the region has a history of higher breast cancer incidence that is unexplained by the population's age, in-migration, mammography use, or established breast cancer risk factors. We conducted a case-control study to investigate whether exposure to drinking water contaminated by wastewater increases the risk of breast cancer. Methods Participants were 824 Cape Cod women diagnosed with breast cancer in 1988–1995 and 745 controls who lived in homes served by public drinking water supplies and never lived in a home served by a Cape Cod private well. We assessed each woman's exposure yearly since 1972 at each of her Cape Cod addresses, using nitrate nitrogen (nitrate-N levels measured in public wells and pumping volumes for the wells. Nitrate-N is an established wastewater indicator in the region. As an alternative drinking water quality indicator, we calculated the fraction of recharge zones in residential, commercial, and pesticide land use areas. Results After controlling for established breast cancer risk factors, mammography, and length of residence on Cape Cod, results showed no consistent association between breast cancer and average annual nitrate-N (OR = 1.8; 95% CI 0.6 – 5.0 for ≥ 1.2 vs. Conclusion Results did not provide evidence of an association between breast cancer and drinking water contaminated by wastewater. The computer mapping methods used in this study to link routine measurements required by the Safe Drinking Water Act with interview data can enhance individual-level epidemiologic studies of multiple health

    Full Text Available Breast cancer rates and median age of onset differ between Western Europe and North Africa. In Western populations, 5 to 10 % of breast cancer cases can be attributed to major genetic factors such as BRCA1 and BRCA2, while this attribution is not yet well defined among Africans. To help determine the contribution of BRCA1 mutations to breast cancer in a North African population, we analysed genomic DNA from breast cancer cases ascertained in Algiers. Both familial cases (at least three breast cancers in the same familial branch, or two with one bilateral or diagnosed before age 40 and sporadic cases less than 38 years of age were studied. Complete sequencing plus quantitative analysis of the BRCA1 gene was performed. 9.8 % (5/51 of early-onset sporadic and 36.4 % (4/11 of familial cases were found to be associated with BRCA1 mutations. This is in contrast 10.3 % of French HBOC families exhibiting a BRCA1 mutation. One mutation, c.798_799delTT, was observed in two Algerian families and in two families from Tunisia, suggesting a North African founder allele. Algerian non-BRCA1 tumors were of significantly higher grade than French non-BRCA tumors, and the age at diagnosis for Algerian familial cases was much younger than that for French non-BRCA familial cases. In conclusion, we observed a much higher frequency of BRCA1 mutations among young breast cancer patients than observed in Europe, suggesting biological differences and that the inclusion criterea for analysis in Western Europe may not be applicable for the Northern African population.

    Full Text Available Abstract Male breast cancer accounts for 1% of all breast cancer cases, and men tend to be diagnosed at an older age than women (mean age is about 67 years. Several risk factors have been identified, such as genetic and hormonal abnormalities. The present study reported the case of a 25-year-old man who was diagnosed with an advanced invasive ductal carcinoma; however, he did not have any important risk factors. Even though more data is emerging about this disease, more efforts to understand risk factors, treatment options and survival benefits are needed. In this case, we discussed the risk factors as well as the impaired fertility associated with breast cancer therapies.

    A 64-year-old woman noticed a lump of the right breast and consulted our outpatient clinic. She had undergone multiple excisional biopsies of fibroadenomas in both breasts and mastectomy for invasive ductal carcinoma (IDC) of the left breast. After completing 5 years of treatment with adjuvant tamoxifen, she had undergone screening with annual physical examinations and occasional computed tomography. She was declared recurrence-free 13 years after breast cancer surgery, although lumps were detected in the right breast, probably due to fibroadenomas. Mammography, ultrasonography, and magnetic resonance imaging revealed that the lump was irregularly shaped, 2 cm in diameter, and adjacent to a fibroadenoma with macrocalcification. Two axillary lymph nodes were enlarged and suggestive of metastasis. A core needle biopsy revealed IDC of the right breast. She underwent a right partial mastectomy with axillary lymph node dissection. The IDC was 2 cm in diameter, of nuclear grade 2, and adjacent to a 0.7-cm fibroadenoma with a macrocalcification. The margins of the IDC close to the fibroadenoma were clearly demarcated by the fibrous capsule of the fibroadenoma. Four axillary lymph nodes were positive for metastasis. In the present case the presence of fibroadenoma might have interfered with the early detection of the contralateral IDC. The history of multiple excisions of fibroadenomas and mastectomy for breast cancer suggests an increased risk of contralateral breast cancer for the patient's entire life; therefore, regular annual follow-up, such as physical examinations and mammography, is recommended.

    Full Text Available Abstract Background Male breast cancer (MBC is a rare disease representing less than 1% of all malignancies in men and only 1% of all incident breast cancers. Our study details clinico-pathological features, treatments and prognostic factors in a large Moroccan cohort. Findings One hundred and twenty-seven patients were collected from 1985 to 2007 at the National Institute of Oncology in Rabat, Morocco. Median age was 62 years and median time for consultation 28 months. The main clinical complaint was a mass beneath the areola in 93, 5% of the cases. Most patients have an advanced disease. Ninety-one percent of tumors were ductal carcinomas. Management consisted especially of radical mastectomy; followed by adjuvant radiotherapy and hormonal therapy with or without chemotherapy. The median of follow-up was 30 months. The evolution has been characterized by local recurrence; in twenty two cases (17% of all patients. Metastasis occurred in 41 cases (32% of all patients. The site of metastasis was the bone in twenty cases; lung in twelve cases; liver in seven case; liver and skin in one case and pleura and skin in one case. Conclusion Male breast cancer has many similarities to breast cancer in women, but there are distinct features that should be appreciated. Future research for better understanding of this disease at national or international level are needed to improve the management and prognosis of male patients.

    Full Text Available Abstract Background Household cleaning and pesticide products may contribute to breast cancer because many contain endocrine disrupting chemicals or mammary gland carcinogens. This population-based case-control study investigated whether use of household cleaners and pesticides increases breast cancer risk. Methods Participants were 787 Cape Cod, Massachusetts, women diagnosed with breast cancer between 1988 and 1995 and 721 controls. Telephone interviews asked about product use, beliefs about breast cancer etiology, and established and suspected breast cancer risk factors. To evaluate potential recall bias, we stratified product-use odds ratios by beliefs about whether chemicals and pollutants contribute to breast cancer; we compared these results with odds ratios for family history (which are less subject to recall bias stratified by beliefs about heredity. Results Breast cancer risk increased two-fold in the highest compared with lowest quartile of self-reported combined cleaning product use (Adjusted OR = 2.1, 95% CI: 1.4, 3.3 and combined air freshener use (Adjusted OR = 1.9, 95% CI: 1.2, 3.0. Little association was observed with pesticide use. In stratified analyses, cleaning products odds ratios were more elevated among participants who believed pollutants contribute "a lot" to breast cancer and moved towards the null among the other participants. In comparison, the odds ratio for breast cancer and family history was markedly higher among women who believed that heredity contributes "a lot" (OR = 2.6, 95% CI: 1.9, 3.6 and not elevated among others (OR = 0.7, 95% CI: 0.5, 1.1. Conclusions Results of this study suggest that cleaning product use contributes to increased breast cancer risk. However, results also highlight the difficulty of distinguishing in retrospective self-report studies between valid associations and the influence of recall bias. Recall bias may influence higher odds ratios for product use among participants who believed

  11. Aberrant DNA methylation of cancer-related genes in giant breast fibroadenoma: a case report

    Directory of Open Access Journals (Sweden)

    Orozco Javier I

    2011-10-01

    Full Text Available Abstract Introduction Giant fibroadenoma is an uncommon variant of benign breast lesions. Aberrant methylation of CpG islands in promoter regions is known to be involved in the silencing of genes (for example, tumor-suppressor genes and appears to be an early event in the etiology of breast carcinogenesis. Only hypermethylation of p16INK4a has been reported in non-giant breast fibroadenoma. In this particular case, there are no previously published data on epigenetic alterations in giant fibroadenomas. Our previous results, based on the analysis of 49 cancer-related CpG islands have confirmed that the aberrant methylation is specific to malignant breast tumors and that it is completely absent in normal breast tissue and breast fibroadenomas. Case presentation A 13-year-old Hispanic girl was referred after she had noted a progressive development of a mass in her left breast. On physical examination, a 10 × 10 cm lump was detected and axillary lymph nodes were not enlarged. After surgical removal the lump was diagnosed as a giant fibroadenoma. Because of the high growth rate of this benign tumor, we decided to analyze the methylation status of 49 CpG islands related to cell growth control. We have identified the methylation of five cancer-related CpG islands in the giant fibroadenoma tissue: ESR1, MGMT, WT-1, BRCA2 and CD44. Conclusion In this case report we show for the first time the methylation analysis of a giant fibroadenoma. The detection of methylation of these five cancer-related regions indicates substantial epigenomic differences with non-giant fibroadenomas. Epigenetic alterations could explain the higher growth rate of this tumor. Our data contribute to the growing knowledge of aberrant methylation in breast diseases. In this particular case, there exist no previous data regarding the role of methylation in giant fibroadenomas, considered by definition as a benign breast lesion.

    We investigate the familial risks of cancers of the breast and ovary, using data pooled from three population-based case-control studies of ovarian cancer that were conducted in the United States. We base estimates of the frequency of mutations of BRCA1 (and possibly other genes) on the reported occurrence of breast cancer and ovarian cancer in the mothers and sisters of 922 women with incident ovarian cancer (cases) and in 922 women with no history of ovarian cancer (controls). Segregation analysis and goodness-of-fit testing of genetic models suggest that rare mutations (frequency .0014; 95% confidence interval .0002-.011) account for all the observed aggregation of breast cancer and ovarian cancer in these families. The estimated risk of breast cancer by age 80 years is 73.5% in mutation carriers and 6.8% in noncarriers. The corresponding estimates for ovarian cancer are 27.8% in carriers and 1.8% in noncarriers. For cancer risk in carriers, these estimates are lower than those obtained from families selected for high cancer prevalence. The estimated proportion of all U.S. cancer diagnoses, by age 80 years, that are due to germ-line BRCA1 mutations is 3.0% for breast cancer and 4.4% for ovarian cancer. Aggregation of breast cancer and ovarian cancer was less evident in the families of 169 cases with borderline ovarian cancers than in the families of cases with invasive cancers. Familial aggregation did not differ by the ethnicity of the probands, although the number of non-White and Hispanic cases (N = 99) was sparse. 14 refs., 3 figs., 6 tabs.

  13. Early breast cancer

    International Nuclear Information System (INIS)

    The therapy of early breast cancer has been changing during the last decennium. It requires a multi-disciplinary approach and in each of these disciplines improvements have been implemented. The result is that treatment schedules can now be adapted to specific subgroups. In this review early breast cancer is defined as operable disease, using the criteria set out by Haagensen. Emphasis is given to describing the new developments in prognostic criteria, since these form the basis for creating subgroups for specific treatment schedules. Distinction is made between the factors relating to growth rate and those relating to metastatic potential. Data on screening promises a beneficial effect of the implementation of screening in national health care programs. Important shifts are seen in treatment schedules; the place of postoperative radiotherapy after classic ablative treatment is being challenged, whereas it plays a major role in the new breast conserving therapy schedules. The data mentioned in the review suggest that a large proportion of 'operable' cases can be treated with breast conservation but details in the technique of breast conserving therapy are still under investigation. They form a major part of the coming prospective studies in breast cancer. Improvements in reconstruction techniques, creating better cosmetic results, make reconstruction more competitive with breast conserving therapy. The use of chemotherapy and endocrine manipulation in early breast cancer has now been clearly confirmed by the overview technique by the Peto-group, thanks to all efforts of individual trialists together.

  14. Passive Smoking and Breast Cancer Risk among Non-Smoking Women: A Case-Control Study in China.

    Directory of Open Access Journals (Sweden)

    Bin Li

    Full Text Available The role of passive smoking on breast cancer risk was unclear. This study aimed to evaluate the association between passive smoking and breast cancer risk among Chinese women.A hospital-based case-control study, including 877 breast cancer cases and 890 controls, frequency-matched by age and residence, was conducted. A structured questionnaire was used to collect information on passive smoking history through face-to-face interview by trained interviewers. Unconditional logistic regression models were used to estimate the association between passive smoking and breast cancer risk. A positive association between any passive smoking exposure and breast cancer risk was observed. Compared with women who were never exposed to passive smoking, women who were ever exposed had a higher breast cancer risk, with the adjusted odds ratio (OR and 95% confidence interval (CI of 1.35 (1.11-1.65. Similar result was found on home passive smoking exposure and breast cancer risk, but not on workplace passive smoking exposure. Women who were ever exposed to tobacco smoke at home had a higher risk of breast cancer compared with never exposed women, with the adjusted OR (95% CI of 1.30 (1.05-1.61. Home passive smoking exposure showed significant dose-response relationships with breast cancer risk in smoker-years, cigarettes/day and total pack-years (Ptrend=0.003, 0.006 and 0.009, respectively. An increased total smoker-years of any passive exposure significantly elevated the risk of breast cancer (Ptrend<0.001. Positive associations and dose-response relationships were found among postmenopausal women and all subtypes of estrogen receptor (ER and progesterone receptor (PR status of breast cancer.Passive smoking was associated with an increased risk of breast cancer among non-smoking Chinese women. A stronger positive association with breast cancer risk was seen mainly among postmenopausal women.

    Pilomatrixoma or calcifying epithelioma of Malherbe is a rare, benign, skin tumour originating from piliferous follicles; breast localization is considered to be very rare. These lesions can origin from the peri-areolar piliferous bulbs and, due to the clinical and imaging features, be easily misdiagnosed as a breast neoplasm. We present a case of pilomatrixoma of the left breast in a woman of 43 years appearing as a firm, deep nodule in the external quadrants. The lesion had mammographic and sonographic malignant features, but histological analysis on core-needle biopsy and surgical specimens revealed this unusual benign lesion. PMID:24421922

  17. Sequencing analysis of SLX4/FANCP gene in Italian familial breast cancer cases.

    Directory of Open Access Journals (Sweden)

    Irene Catucci

    Full Text Available Breast cancer can be caused by germline mutations in several genes that are responsible for different hereditary cancer syndromes. Some of the genes causing the Fanconi anemia (FA syndrome, such as BRCA2, BRIP1, PALB2, and RAD51C, are associated with high or moderate risk of developing breast cancer. Very recently, SLX4 has been established as a new FA gene raising the question of its implication in breast cancer risk. This study aimed at answering this question sequencing the entire coding region of SLX4 in 526 familial breast cancer cases from Italy. We found 81 different germline variants and none of these were clearly pathogenic. The statistical power of our sample size allows concluding that in Italy the frequency of carriers of truncating mutations of SLX4 may not exceed 0.6%. Our results indicate that testing for SLX4 germline mutations is unlikely to be relevant for the identification of individuals at risk of breast cancer, at least in the Italian population.

  18. Two cases of bronchiolitis obliterans organizing pneumonia (BOOP) induced radiotherapy after surgery of breast cancer

    International Nuclear Information System (INIS)

    We report two cases of bronchiolitis obliterans organizing pneumonia (BOOP) induced radiotherapy after surgery of breast cancer. One of the patients was a 58-year-old woman. She underwent a conserving surgery for bilateral breast cancers, and received radiation therapy to the remaining part of bilateral breasts. Two months after the termination of irradiation, cough, fever and general fatigue developed. We clinically diagnosed this case as BOOP after radiation therapy. After initiation of oral steroid therapy, the clinical symptoms and radiographic findings disappeared. Another patient was a 57 year-old woman. She underwent radical mastectomy for right breast cancer. A month after the operation, she suffered from local recurrence, so radiation therapy to the thoracic wall was performed. After irradiation, resection of the thoracic wall lesion was performed because of malignancy from local skin biopsy specimen. Two months after the termination of irradiation, cough, dyspnea and fever developed. We clinically diagnosed this case as radiation-induced BOOP by bronchoalveolar lavage (BAL) and transbronchial lung biopsy (TBLB) findings. After an initiation of steroid therapy, the clinical symptoms and radiographic findings disappeared. It is important to be aware of BOOP as a complication in the patient who was given radiation after surgery of breast cancer. (author)

    Cadmium, an environmental pollutant, may act like an estrogen and be a potential risk factor for estrogen-dependent diseases such as breast cancer. We examined the hypothesis that higher dietary cadmium intake is associated with risk of overall and hormone receptor-defined breast cancer in Japanese women, a population with a relatively high cadmium intake. The study was conducted under a case-control design in 405 eligible matched pairs from May 2001 to September 2005 at four hospitals in Nagano Prefecture, Japan. Dietary cadmium intake was estimated using a food frequency questionnaire. Multivariable-adjusted odds ratios (ORs) and 95% confidence intervals (CIs) of breast cancer and its hormone-receptor-defined subtypes were calculated by tertile of dietary cadmium intake. We found no significant association between dietary cadmium and risk of total breast cancer in either crude or multivariable-adjusted analysis. Adjusted ORs for tertiles of cadmium intake were 1.00, 1.19, and 1.23 (95% CI, 0.76-2.00; P for trend=0.39) for whole breast cancer. Further, no significant associations were seen across strata of menopausal status, smoking, and diabetes in multivariable-adjusted models except for adjusted OR for continuous cadmium intake in postmenopausal women. A statistically significant association was found for estrogen receptor-positive (ER+) tumors among postmenopausal women (adjusted OR=1.00, 1.16, and 1.94 [95% CI, 1.04-3.63; P for trend=0.032]). Although the present study found no overall association between dietary cadmium intake and breast cancer risk, higher cadmium intake was associated with increased risk of ER+ breast cancer in postmenopausal women, at least at regular intake levels in Japanese women in the general population. Further studies are needed to confirm this association. PMID:23608001

    Full Text Available Abstract Background Primary non-Hodgkin lymphoma (NHL of the breast represents 0.04–0.5% of malignant lesions of the breast and accounts for 1.7–2.2% of extra-nodal NHL. Most primary cases are of B-cell phenotype and only rare cases are of T-cell phenotype. Anaplastic large cell lymphoma (ALCL is a rare T-cell lymphoma typically seen in children and young adults with the breast being one of the least common locations. There are a total of eleven cases of primary ALCL of the breast described in the literature. Eight of these cases occurred in proximity to breast implants, four in relation to silicone breast implant and three in relation to saline filled breast implant with three out of the eight implant related cases having previous history of breast cancer treated surgically. Adjuvant postoperative chemotherapy is given in only one case. Secondary hematological malignancies after breast cancer chemotherapy have been reported in literature. However in contrast to acute myeloid leukemia (AML, the association between lymphoma and administration of chemotherapy has never been clearly demonstrated. Case Presentation In this report we present a case of primary ALCL of the breast arising in reconstruction mamoplasty capsule of saline filled breast implant after radical mastectomy for infiltrating ductal carcinoma followed by postoperative chemotherapy twelve years ago. Conclusion Primary ALK negative ALCL arising at the site of saline filled breast implant is rare. It is still unclear whether chemotherapy and breast implantation increases risk of secondary hematological malignancies significantly. However, it is important to be aware of these complications and need for careful pathologic examination of tissue removed for implant related complications to make the correct diagnosis for further patient management and treatment. It is important to be aware of this entity at this site as it can be easily misdiagnosed on histologic grounds and to exclude

    Full Text Available Introduction & Background: Benign lesions are very common in breast. The most important consideration for physicians is to differentiate benign processes from malignant ones .Hence the clinicians and radi-ologists both wish to differentiate them even before surgical procedures. The Iranian Center for Breast Cancer linked to Jahad Daneshgahi Center is a referral place for patients with breast complaints. Patients & Methods: Retrospective study of sonographic findings of 111 patients with benign patho-logic diagnosis revealed 72.1% accuracy for sonogra-phy in diagnosing benign masses. In 31 cases (27.9%, the sonographic diagnosis was incorrect. Among the different benign lesions, the most common lesions were cysts, fibradenomas, and fibrocystic changes with respective sonographic accuracy of 100%, 90%, and 62.5%. Results: It shows that sonography has a high sensitiv-ity for diagnosis of benign breast lesions and this sen-sitivity is higher in cysts and fibradenomas which are the most common benign pathologies of breast. Conclusion: As a result, in this center sonography is an imaging modality for evaluating benign breast le-sion especially in young patients with dense breasts and palpable masses. Its unique role in diagnosis of the cysts is valuable especially to avoid repeated biopsies.

  5. Breast lymphoscintigraphy for sentinel node identification in clinically axillary node negative breast cancer: A preliminary report of 35 cases

    International Nuclear Information System (INIS)

    Full text: Lymphoscintigraphy is a sensitive, minimally invasive method for identifying sentinel lymph node (SLN). It has been extensively validated in malignant melanoma, penile cancer and recently in breast cancer. The aims of this study were to analyze and determine the clinical value of lymphoscintigraphy in SLN localization in woman undergoing surgery for breast cancer and to evaluate the predictive value of SLN versus axillary lymph node status in these patients. Pre-operative breast lymphoscintigraphy were preformed in 35 female patients with breast cancer and clinically negative axillary node. Mean age was 52.8 years (range 38 to 73 years). Prior to surgery, 74 MBq of Tc-99m nanocolloid in 0.2 to 0.5 ml was injected intra-dermally over the tumor mass. Immediately after injection, anterior dynamic images were acquired for 20 minutes, followed by anterior and lateral views static images at 30 minute, 1 hour and 2 hour using single-head gamma camera until SLN visualized. The SLN location was marked externally on skin. All patients underwent standard modified radical mastectomy with axillary node dissection. All lymph nodes were examined carefully by a skilled histopathologist. SLNs were assessed by visual inspection of both dynamic and static images. Comparison of SLN and axillary lymph node histopathologic results was done in order to define the means of SLN biopsy's ability to reflect the final status of axilla. The mean size of the primary breast tumor mass was 2.54 cm (1.0 to 4.0 cm). In 20/35 (57.1%), the SLNs were visualized in 20-minute dynamic imaging. In 12 patients, the SLNs were seen after delayed imaging and/or repositioning the patient. Overall estimated SLN identification rate was 91.43%. Of those 32 cases in whom the SLNs were localized on lymphoscintigraphy, 9 cases were positive for metastatic tumors and the rest were negative for tumor involvement. Four out of these 9 cases, SLN was the only node that contained metastatic tumor cells and in 5

    We report a case of recurrent cough and migratory pulmonary infiltrates in a 55-year-old woman after adjuvant thoracic radiotherapy for breast cancer. The pulmonary infiltrates were initially limited to the area adjacent to the irradiated breast, but later migrated to the opposite lung. The diagnosis of bronchiolitis obliterans organizing pneumonia (BOOP) was made using transbronchial biopsy, which disclosed intraluminal fibrosis in the distal airspace, together with a radiographic appearance typical of BOOP. This case was assumed to be in a series of reported cases of BOOP primed by radiotherapy. (author)

    We analyzed the treatment outcomes and prognostic factors of breast conserving surgery, followed by postoperative radiotherapy. Materials and Methods: A total of 424 breast cancer patients treated with breast conserving surgery and postoperative radiotherapy between February 1992 and January 2001 were retrospectively analyzed. A quadrantectomy and axillary lymph node dissection was performed in 396 patients. A total of 302 patients had T1 disease, and 122 patients had T2 disease. Lymph node involvement was confirmed in 107 patients. Whole breast irradiation was administered at up to 50.4 Gy in 28 fractions, followed by a 10 Gy boost in 5 fractions to the tumor bed. In addition, 57 patients underwent regional lymph node irradiation. Moreover, chemotherapy was administered in 231 patients. A regimen consisting of cyclophosphamide, methotrexate, and 5-fluorouracil was most frequently used with 170 patients. The median follow-up time was 64 months. Results: The 5-year local control rate was 95.6%. During the follow-up period, local tumor recurrence was observed in 15 patients. The 5-year overall and disease-free survival rates were 93.1% and 88.7%, respectively. The 5-year overall survival rates, by stage, were 94.8% for stage I, 95.0% for stage IIA, 91.1% for stage IIB, 75.9% for stage IIIA, and 57.1% for stage IIIC. As for disease-free survival, the corresponding figures, by stage (in the same order), were 93.1%, 89.4%, 82.8%, 62.0%, and 28.6%, respectively. The advanced N stage (p=0.0483) was found to be a significant prognostic factor in predicting poor overall survival, while the N stage (p=0.0284) and age at diagnosis (p=0.0001) were associated with disease-free survival. Conclusion: This study has shown that breast conserving surgery and postoperative radiotherapy for early breast cancer results was excellent for local control and survival.

    Metastatic breast cancer involving the hepatobiliary tract or ascites secondary to peritoneal carcinomatosis has been well described. Luminal gastrointestinal tract involvement is less common and recognition of the range of possible presentations is important for early and accurate diagnosis and treatment. We report 6 patients with a variety of presentations of metastatic breast cancer of the luminal gastrointestinal tract. These include oropharyngeal and esophageal involvement presenting as dysphagia with one case of pseudoachalasia, a linitis plastica-like picture with gastric narrowing and thickened folds, small bowel obstruction and multiple strictures mimicking Crohn's disease, and a colonic neoplasm presenting with obstruction. Lobular carcinoma,representing only 10% of breast cancers is more likely to metastasize to the gastrointestinal tract. These patients presented with gastrointestinal manifestations after an average of 9.5 years and as long as 20 years from initial diagnosis of breast cancer. Given the increased survival of breast cancer patients with current therapeutic regimes, more unusual presentations of metastatic disease, including involvement of the gastrointestinal tract can be anticipated.

    Male breast cancer is rare, with some pathological and radiological differences from female breast cancer. There is less familiarity with the imaging appearances of male breast cancer, due to its rarity and the more variable use of preoperative imaging. This review will illustrate the commonest imaging appearances of male breast cancer, with emphasis on differences from female breast cancer and potential pitfalls in diagnosis, based on a 10 year experience in our institution.

    Full Text Available Abstract Background Many women in Iran have a relatively high body mass index. To investigate whether the condition contributes to excess breast cancer cases, a case-control study was conducted to assess the relationships between anthropometric variables and breast cancer risk in Tehran, Iran. Methods All incident cases of breast cancer in the Iranian Centre for Breast Cancer (ICBC were identified through the case records. Eligible cases were all postmenopausal women with histological confirmed diagnosis of breast cancer during 1996 to year 2000. Controls were randomly selected postmenopausal women attending the ICBC for clinical breast examination during the same period. The body mass index (BMI was calculated based on weights and heights as measured by the ICBC nursing staff. Both tests for trend and logistic regression analysis were performed to calculate odds ratios and 95% confidence intervals as measures of relative risk. Results In all, 116 breast cancer cases and 116 controls were studied. There were no significant differences between cases and control with regard to most independent variables studied. However, a significant difference was observed between cases and controls indicating that the mean BMI was higher in cases as compared to controls (P = 0.004. Performing logistic regression analysis while controlling for age, age at menopause, family history of breast cancer and parity, the results showed that women with a BMI in the obese range had a three fold increased risk of breast cancer [odds ratio (OR = 3.21, 95% confidence interval (CI: 1.15–8.47]. Conclusion The results suggest that obesity in postmenopausal women could increase risk of breast cancer and it merits further investigation in populations such as Iran where it seems that many women are short in height, and have a relatively high body mass index.

    Cachexia, a wasting syndrome associated with advanced cancer and metastasis, is rarely documented in breast cancer patients. However, the incidence of cachexia in breast cancer is now thought to be largely underestimated. In our case report of a breast cancer patient with bone metastasis monitored during the course of her treatment, we document the development of cachexia by image analysis in relation to her metastatic burden. Elucidation of the link between metastatic burden and cachexia could unveil a highly specific screening process for metastasis, by assessing true muscle mass loss. Our patient was a 49-year-old premenopausal woman, with metastatic invasive ductal breast carcinoma in the vertebral and iliac bones on presentation, which progressed with new metastases to her hips, thigh bones, and vertebrae. In the two-year period, that is between her diagnosis and death, she lost >10% of her baseline weight. During these two years, we retrospectively identified a decrease in paraspinal muscle (PM) at the third lumbar vertebra followed by a sharp decline in weight. The increased tumor burden over time in metastatic sites was accompanied by a decrease in abdominal muscle and visceral and subcutaneous fat and was followed by the patient’s demise. The increasing tumor burden in the patient was correlated with the mass of other tissues to determine the tissue that could best serve as a surrogate marker to cachexia and tumor burden. We noted a strong negative correlation between PM area and metastatic tumor area at the third lumbar vertebral level, with PM loss correlating to increasing tumor burden. The monitoring of PM wasting may serve as a marker, and therefore a prognostic factor, for both cachexia and extent of metastatic disease, especially in breast cancer, where metastasis to bone is frequent. Based on our data and review of the literature in this case study, longitudinal monitoring of cachexia in the selected muscle groups can give clinicians early

    The treatment of locoregionally recurrent breast cancer in patients who have previously undergone radiation therapy is challenging. Special techniques are often required that both eradicate the disease and minimize the risks of retreatment. We report the case of a patient with an early-stage left breast cancer who developed inflammatory-type recurrence requiring re-irradiation of the chest wall using bolus electron conformal therapy with image-guided treatment delivery. The patient was a 51-year-old woman who had undergone lumpectomy, axillary lymph node dissection, and adjuvant whole-breast radiation therapy for a stage I left breast cancer in June 1998. In March 2009, she presented at our institution with biopsy-proven recurrent inflammatory carcinoma and was aggressively treated with multi-agent chemotherapy followed by mastectomy that left a positive surgical margin. Given the patient's prior irradiation and irregular chest wall anatomy, bolus electron conformal therapy was used to treat her chest wall and draining lymphatics while sparing the underlying soft tissue. The patient still had no evidence of disease 21 months after treatment. Our results indicate that bolus electron conformal therapy is an accessible, effective radiation treatment approach for recurrent breast cancer in patients with irregular chest wall anatomy as a result of surgery. This approach may complement standard techniques used to reduce locoregional recurrence in the postmastectomy setting.

    Due to their lipophilic properties, dioxins (PCDD/PCDFs) and other organohalogen compounds bioaccumulate in the food chain, with diet accounting for over 90% of non-occupational exposures. To date, few epidemiologic studies have examined the relationship between dioxins and breast cancer in human populations. Most have examined risks in occupational cohorts or in populations exposed to dioxins from the Seveso accident6-8. Results from these studies have been conflicting and have largely been limited by a lack of individual-level measures of exposure, small numbers of cases, and inability to account for established breast cancer risk factors. Very little is known about the potential health effects of low-level environmental dioxin contamination. We present data on PCDD/PCDFs, organochlorine pesticides (OCPs), polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs) in adipose tissues of women participating in a breast cancer case-control study centered in the San Francisco Bay Area. In addition, we examine distributions of these chemicals in breast and abdominal adipose of women undergoing mastectomies with concurrent breast reconstruction. If concentrations were equivalent, use of abdominal adipose would greatly enhance the pool for controls for future epidemiological studies.

  20. A nested case-control study on female breast cancer risk among medical diagnostic X-ray workers in China

    International Nuclear Information System (INIS)

    Objectives: To research whether prolonged or repeated low-level ionizing radiation can induce female breast cancer or not and to investigate other risk factors related to breast cancer risk, a nested case-control study was done. Methods: 30 cases of breast cancers were enrolled in the study, 4 normal persons were selected from X-ray workers as controls to match each case. Logistic regression model was used for risk analysis. Results: 1) Accumulative breast dose is a significant risk factor, odds ratio (OR) between two dose levels (10c Gy) is 1.73 (95%CI = 1.05-2.84). 2) ORs of other two factors, obesity and family history of breast cancer, are 4.07 (P = 0.01) and 26.67 (P = 0.024) respectively. 3) Interaction may exist between occupational X-ray exposure and obesity or non-lactation. Conclusions: Longtime and low-level occupational X-ray exposure may relate to excess risk of female breast cancer among medical diagnostic X-ray workers. Family history of breast cancer and obesity are also the significant risk factors of the cancer. The existence of obesity and non-lactation may enhance the effect of radiation-induced breast cancer

    Of ophthalmic involvement from metastatic breast cancer, extraocular/intraorbital metastases are extremely rare. External beam radiotherapy has been a mainstay palliation for symptomatic orbital metastases. We present a case of bilateral orbital metastases from breast cancer successfully treated with stereotactic radiotherapy (SRT). A 38-year-old woman presented with decreased vision in the right eye for 3 weeks. Eight months previously, she underwent whole-brain radiotherapy for multiple brain metastases from breast cancer. Visual acuity was hand motion, and the eyelid closed incompletely in the affected eye. Computed tomography scans showed a 3-cm extraconal mass in the right orbit. She underwent temporary tarsorrhaphy followed by SRT. A total dose of 39 Gy was delivered to the right orbital mass in three daily fractions. Four months later, her visual function was normal in both eyes and the right orbital mass disappeared. A new lesion was detected in the left orbit. She underwent SRT for the left orbital lesion using the same dose-fractionation schedule. No radiation-related toxicities were observed. She died 19 months after the first SRT. Our case suggests that SRT may be an effective and safe treatment option in patients with orbital metastases from breast cancer. PMID:21999613

    Deleted in colorectal carcinoma (DCC), a netrin-1 dependence receptor, is correlated with cell progression, migration, and adhesion. Evidence indicated that DCC was frequently down-regulated in many cancers. However, the association of DCC with breast cancer remains uncertain. We conducted a case-control study to investigate the impact of three DCC gene variants (rs2229080, rs7504990, and rs4078288) on breast cancer susceptibility in Chinese women. This study included 560 breast cancer patients and 583 age-matched healthy controls from Northwest China. The three gene variants were genotyped via Sequenom MassARRAY. Odds ratios (ORs) and 95% confidence intervals (CIs) were utilized to evaluate the associations. We found that individuals with the rs2229080 C/G, C/C, and C/G-CC genotypes had a higher breast cancer risk, and the minor allele C was associated with increased breast cancer risk in an allele model. We observed a significantly decreased breast cancer risk with the rs7504990 C/T, T/T, and C/T-T/T genotypes, and the minor allele T was protective against breast cancer in an allele model. In addition, rs2229080 was associated with the axillary lymph node (LN) metastasis status. An age-stratified analysis revealed an association between rs2229080 and reduced breast cancer risk among older patients (≥ 49 years). Furthermore, the haplotype analysis showed that the Crs2229080Crs7504990Ars4078288 haplotype was associated with a decreased breast cancer risk. However, the results indicated a lack of association between rs4078288 and breast cancer risk. These findings affirmed that rs2229080 and rs7504990 polymorphisms in DCC might be related with breast cancer susceptibility in Chinese women.

  6. Soft tissue sarcomas after radiation treatment for breast cancer. Three case studies and review of literature

    International Nuclear Information System (INIS)

    Aims: By means of 3 cases with infield soft tissue carcinomas after radiotherapy for breast cancer, symptoms and therapy are described. Consequences for treatment planning and patient's information before radiotherapy for breast cancer are discussed. Patients: Three of 1,025 patients with breast cancer irradiated from 1984 to 1997 suffered from infield secondary soft tissue sarcomas. The latency periods were 61, 49 and 59 months. Two patients had been treated with breast-conserving therapy (computerized planning, 50 Gy to reference point, 5 times 2 Gy/week, 5-MV photons), 1 patient received a local boost dose of 15 Gy (10-MeV electrons), patient 3 radiotherapy of the thoracic wall and regional lymph nodes after mastectomy using 12-MeV electrons (thoracic wall) and 5-MV photons (lymph node areas) to 50 Gy, 5 times 2 Gy/week. No adjuvant chemotherapy was given. All sarcomas were very extensive, all patients died from local progression and/or distant failure after 17, 13 and 12 months. Results: The incidence of spontaneous sarcomas of the breast in about 0.06%, after operation and radiotherapy 0.09 to 0.45%. No correlations to radiotherapy technique and no risk factors were found. Radiation dose could play a role, but there are very sparse data about this. (orig.)

    OBJECTIVE In Europe and America breast cancer commonly occurs in women of middle and old age, with a median age of about 57 years. Modified radical mastectomy now called standard radical mastectomy, has taken the place of traditional radical mastectomy. Patients with breast cancer at an early stage commonly receive BCT (breast conservative therapy). The TNM stage (especially the lymph node status) affects the prognosis, and adjuvant therapy can improve survival. In China, only a few reports have been pubIished studying large numbers of breast cancer patients. This study was designed to analyze the clinical features, surgical pattern and treatment outcome of resectable breast cancer, as well as to explore the prognostic factors and the effect of adjuvant therapy, with a goal to improve the level of diagnosis and treatment.METHODS Records of the 6,263 patients with resectable breast cancer who had been admitted into our hospital from June 1964 to June 2003 were analyzed retrospectively.RESULTS Of the 6,263 cases, 98.8% were female. Breast cancer occurred most frequently in patients of ages 40~49 years (41.0%), especially in patients 45~49 years old (25.2%). A breast lump, which occurred in 96.2% of the patients, was the main clinical manifestation. The overall 5- and 10-year survival rates were 75.16% and 40.44%. Of the patients in TNM stages 0-1,Ⅱ, and Ⅲ, the 5-year survival rates were 96.8%, 73.7% and 46.4% respectively and the 10-year survival rates were 78.7%, 64.6% and 33.5% respectively. The 5-, and 10-year survival rates were higher in the lymph node negative group than in the lymph node positive group (80.3% vs. 55.6%, and 59.2% vs. 31.9%, P<0.01). Since the 1980s there was no significant difference in survival rates of patients who received a radical mastectomy compared to a modified radical mastectomy(P>0.05). Of the 73 patients who underwent breast conservative therapy, no local recurrence or metastasis occurred during a maximal follow-up of 17

    Breast Cancer, with a life-time prevalence of about 10-12%, is the most common cancer in women. In 2013, the actress Angelina Jolie, by announcing she had a double mastectomy, increased the awareness of a family history of breast and ovarian cancer and the treatment available to reduce the inherited risks. In Germany, each year about 25 out of 100,000 women (age-standardized according to European Standard) die of the disease. The number of newly diagnosed cases is about 72,000 per year. In comparison, many other countries record higher levels. Investing in the development of new therapies has therefore been key for many years. Prevention programs, such as the mammography screening are publicly touted, in both cases with the aim to reduce breast cancer mortality. To accurately assess the risk in underwriting, it is important to know about the risk factors for the development of breast cancer, as well as the latest advances in prevention, therapy and their prognostic classification. The following article provides an overview. PMID:25000626

    Full Text Available Abstract Background The effect of antioxidants on breast cancer is still controversial. Our objective was to assess the association between antioxidants and breast cancer risk in a large population-based case-control study. Methods The study population included 2,362 cases with pathologically confirmed incident breast cancer (866 premenopausal and 1,496 postmenopausal and 2,462 controls in Canada. Intakes of antioxidants from diet and from supplementation as well as other potential risk factors for breast cancer were collected by a self-reported questionnaire. Results Compared with subjects with no supplementation, 10 years or longer supplementation of zinc had multivariable-adjusted odds ratios (OR and 95% confidence intervals (CI of 0.46 (0.25-0.85 for premenopausal women, while supplementation of 10 years or longer of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc had multivariable-adjusted ORs (95% CIs of 0.74 (0.59, 0.92, 0.58 (0.36, 0.95, 0.79 (0.63-0.99, 0.75 (0.58, 0.97, and 0.47 (0.28-0.78, respectively, for postmenopausal women. No significant effect of antioxidants from dietary sources (including beta-carotene, alpha-carotene, lycopene, lutein and zeaxanthin, vitamin C, vitamin E, selenium and zinc or from supplementation less than 10 years was observed. Conclusions This study suggests that supplementation of zinc in premenopausal women, and supplementation of multiple vitamin, beta-carotene, vitamin C, vitamin E and zinc in postmenopausal women for 10 or more years may protect women from developing breast cancer. However, we were unable to determine the overall effect of total dose or intake from both diet and supplement.

    Breast cancer is frequently associated with venous thromboembolism (VTE). VTE may result in significant morbidity, a substantial economic burden and even leads to patients' death. Risk factor identification and management of VTE in breast cancer patients remains poorly studied. We evaluated breast cancer patients' baseline and treatment characteristics in predicting VTE occurrence as well as its prognosis. We conducted a case-control study of all breast cancer patients with a VTE diagnosed between January 2007 and December 2011 at the Instituto Nacional de Câncer (INCA) in Brazil. Two hundred and twenty five patients developed VTE and were compared with 225 controls, in the 5-year study period. The bulk of the thrombotic events were unilateral (94.2%) VTEs of the lower extremity (78.7%), largely proximally located (78%). VTE occurred more often within the first 3 years after the diagnosis of cancer (66.2%), being more common in the first 6 months (21.8%). Significant predictors of developing VTE were age 50 years and over (OR 1.85, 95% CI: 1.16-2.95), PS equal to or above 3 (OR 2.01, 95% CI: 1.24-3.26), and the presence of a CVC (OR 2.56, 95% CI: 1.42-4.62). This large retrospective analysis of VTE in breast cancer patients confirms that most events occur early in the treatment course. The incidence of VTE was associated with patients' age, PS, and the presence of CVC. Prospective studies are needed to evaluate outpatient thromboprophylaxis for selected groups of patients.

  13. A case of recurrent organizing pneumonia after radiation therapy for postoperative breast cancer

    International Nuclear Information System (INIS)

    We report the case of a 61-year-old female patient with breast cancer who developed recurrent organizing pneumonia outside the radiation field after radiation therapy for postoperative breast cancer. The patient had received tangential radiation therapy and aromatase inhibitors for postoperative breast cancer. Chest computed tomography confirmed an irregular nodule and ground-glass opacities in the left lower lobe outside the radiation field 10 months after radiation therapy. The nodule demonstrated high uptake on 18F-fluorodeoxyglucose positron emission tomography; therefore, lung cancer could not be ruled out. We performed partial resection of the lung, and a diagnosis of organized pneumonia was made on histopathological examination of the resected specimen. Three days after surgery, a chest radiograph revealed an abnormal shadow in the right lower field. The possibility of organizing pneumonia was considered when pulmonary infiltrate did not respond to conventional antibiotic therapy and the patient recovered completely after treatment with steroids. Furthermore, chest CT performed 4 months after surgery revealed consolidation in the right lower lobe. Again, the patient recovered completely with steroid treatment, indicating the possibility of recurrent organizing pneumonia. The number of such reported cases has increased in recent years; however, the etiology remains unclear. In the case presented, aromatase inhibitor therapy combined with radiation therapy may have been the cause of the organizing pneumonia. (author)

    The level of total adiponectin, a mixture of different adiponectin forms, has been reported associated with breast cancer risk with inconsistent results. Whether the different forms play different roles in breast cancer risk prediction is unclear. To examine this, we measured total and high molecular weight (HMW) adiponectin in a case-control study (1167 sets). Higher circulating HMW adiponectin was negatively associated with breast cancer risk after adjusting for menopausal status and family history of breast cancer (P=0.024). We analyzed the relationship between adiponectin and breast cancer risk in 6 subgroups. Higher circulating HMW adiponectin was also negatively associated with breast cancer risk (P=0.020, 0.014, 0.035) in the subgroups of postmenopausal women, negative family history of breast cancer, BMI>=24.0. Total adiponectin was positively associated with breast cancer (P=0.028) in the subgroup of BMIbreast cancer risk (P=0.034, 0.0116). This study showed different forms of circulating adiponectin levels might play different roles in breast cancer risk. A higher circulating HMW adiponectin is associated with a decreased breast cancer risk, especially in postmenopausal, without family history of breast cancer or BMI>=24.0 subgroups, whereas higher circulating HMW adiponectin levels is a risk factor in women with a family history of breast cancer. Further investigation of different forms of adiponectin on breast cancer risk is needed.

    Full Text Available Over the last three decades an increase in the incidence of breast cancer has been observed in the previously low-risk Asian countries. This study is designed to determine the risk factors of breast cancer for Pakistani women as little information exists in this regard. A case-control study of 564 female breast cancer cases diagnosed at the two cancer hospitals at Lahore (INMOL and SKMCH during the time period Jan 1, 1998 to Dec 31, 1998 was carried out. Four hundred and forty eight women aged 24-80 years out of 564 cases were complete with respect to defined criteria and were eligible for the study. Population-based controls were selected to match for age of cases in the ratio 1:2. The data were analyzed considering ‘all women’ and then separate analyses were done for ‘premenopausal’ and ‘postmenopausal women’. Women with family history of breast cancer, history of consanguineous marriage, smoking and high BMI (≥28 are at increased risk of breast cancer for all three groups. Early menarche (45 years was a strong determinant of breast cancer. Higher number of full-term pregnancies (>3 was protective for ‘all women’ and ‘premenopausal women’ but in case of ‘postmenopausal women’ the poor with higher number of pregnancies were significantly protected. Late age at first FTP (>25 years is a significant risk factor for postmenopausal women.

    The aim of the present study was to assess criterion validity and external reliability of a questionnaire on risk factors for breast cancer. Materials and Methods. Women with breast cancer diagnosis (the cases) (N=40) and matched individuals without cancer (the controls) (N=40) were asked to fill in a questionnaire twice: on a day of admission to hospital (Q1) and on a day before discharge (Q2), with a time interval of 4-6 days. The questionnaire included questions (N=150) on demographic and socioeconomic factors, diseases in the past, family history of cancer, woman's health, smoking, alcohol use, diet, physical activity, and work environment. Criterion validity of the questionnaire Q2 relative to reference questionnaire Q1 was assessed with the Spearman correlation coefficient (SCC); external reliability of the questionnaire was measured in terms of the intraclass correlation coefficient (ICC). Statistical analysis was performed with SPSS 16. Results. The responses to most of the questions on socioeconomic factors, family history on cancer, female health, lifestyle risk factors (smoking, alcohol use, physical activity) correlated substantially in both the cases and the controls with SCC and ICC>0.7 (pcases drank at the ages up to 25 years and 26-35 years as well as time of use of estrogen and estrogens-progestin during menopause by the cases. Moderate and substantial SCC and ICC were determined for different food items. Only the response of the cases on veal consumption did not correlate significantly. Conclusions. The questionnaire on breast cancer risk factors is valid and reliable for most of the questions included. PMID:23803031

    Full Text Available Abstract Introduction Gastrointestinal tract soft tissues metastasis is a well-known occurrence with invasive lobular breast cancer subtypes. Gastric involvement is more common, with reports of both diffuse and localized involvements. Usually, a gastric localized involvement presents as wall thickening with an appearance similar to that of a gastrointestinal stromal tumour; rarely does a localized metastatic deposit grow aggressively to present as a large tumour causing obstructive symptoms. Our case highlights one such unusual presentation in a patient presenting with non-specific gastrointestinal symptoms. To the best of our knowledge, there have been no previous reports on a similar presentation occurring from a localized metastasis. Case presentation A 65-year-old Caucasian woman awaiting an outpatient oral gastroduodenoscopy for symptoms of intermittent vomiting, epigastric pains and weight loss of six weeks’ duration presented acutely with symptoms of haematemesis and abdominal distension. An initial contrast-enhanced computed tomography scan showed a grossly dilated stomach with a locally advanced stenosing tumour mass at the pylorus. Our patient had a history of left mastectomy and axillary clearance followed by adjuvant endocrine therapy for an oestrogen receptor- and progesterone receptor-positive, grade 2, invasive lobular breast cancer. The oral gastroduodenoscopy confirmed the computed tomography findings; biopsies of the pyloric mass on immunohistochemistry stains were strongly positive for pancytokeratin and gross cystic disease fluid proteins, consistent with an invasive lobular breast cancer metastasis. She received a palliative gastrojejunal bypass and her adjuvant endocrine treatment was switched over to exemestane. Conclusion Our case highlights the aggressive behaviour of a localized gastric metastasis that is unusual and unexpected. Gastrointestinal symptomatology can be non-specific and, at times, non-diagnostic on

    The aim of this study was to assess why women delay in getting treatment (i.e. surgery) for breast cancer, as well as to explore on what type of issues are involved in such delay cases. Basic interpretative of qualitative methodology was applied to construct the reality of delay phenomena, and its interaction with social worlds. Six themes were identified: new conception of breast cancer treatment, psychological defenses, health support system, symtomatology experience, model and barriers. The delay issue in breast cancer requires attention as a multidimensional problem as this will facilitate more comprehensive and effective intervention to reduce delay.

  11. Implementing Case Management in New York State’s Partnerships for Publicly Funded Breast Cancer Screening

    2008-04-01

    Full Text Available IntroductionThis research aimed to explore differences in the implementation of case management among local breast cancer screening partnerships in New York State after changes in federal public policy in 1998 and to achieve a better understanding of case management in a new and distinct practice setting. Capacity and willingness to implement change were theorized to explain local differences in implementation. Local breast cancer screening programs that received federal funding through the New York State Department of Health were invited to participate in the study.MethodsA mail survey was administered to the directors of New York’s 53 local breast cancer screening partnerships in 2003. The survey included questions about willingness and capacity to implement case management and a scale to assess case management program philosophy. Factor analysis and correlations were used to compare willingness and capacity with differences in implementation.ResultsTwo common factors — task focus and self-identity focus — were identified as factors that differentiated case management programs. Task-focus partnerships undertook a broader range of tasks but were less likely to report autonomy in making program changes. Self-identity partnerships were less likely to report difficulties with other agencies and scored highly on innovation, involvement in work, and interest in client service. Having a nurse as the case manager, being aware of the standards of case management, and providing health education were associated with both task focus and self-identity focus.ConclusionThe study identified distinct styles of implementation. These styles have implications for the breadth of services provided, such as whether client-level services only are offered. Interagency coordination was facilitated in partnerships with comprehensive case management.

  13. Breast Cancer Metastasis to the Stomach Resembling Early Gastric Cancer

    OpenAIRE

    Eo, Wan Kyu

    2008-01-01

    Breast cancer metastases to the stomach are infrequent, with an estimated incidence rate of approximately 0.3%. Gastric metastases usually are derived from lobular rather than from ductal breast cancer. The most frequent type of a breast cancer metastasis as seen on endoscopy to the stomach is linitis plastica; features of a metastatic lesion that resemble early gastric cancer (EGC) are extremely rare. In this report, we present a case of a breast cancer metastasis to the stomach from an infi...

    Our objective was to analyze detailed anthropometric characterization for risk of breast cancer in Uruguayan women. The design was a case-control study. The setting was Pereira Rossell Women's Hospital, Montevideo, Uruguay. Subjects were 343 incident breast cancer cases and 1,042 frequency-matched healthy controls who were interviewed on menstrual and reproductive story; and a series of skin folds, circumferences, and diameters were measured to calculate fat and muscle fractions and the derived fat-to-muscle ratio (FMR). Odds ratio (ORs) coefficients were taken as estimates of relative risk derived from unconditional logistic regression. Muscle fraction was negatively associated with risk [OR for highest quartile = 0.23, 95% confidence interval (CI) = 0.15-0.34], fat fraction was positively associated (OR = 3.90, 95% CI = 2.62-5.80), and FMR was positively associated (OR = 4.45, 95% CI = 2.99-6.62). Stratified analyses by body mass index levels also showed risk increases for the highest tertiles of FMR, always displaying significant linear trends. Since increases of risk were found in overweight and in normal weight women, results suggest that fractions and amount of muscle and fat components might be risk factors for breast cancer on the basis of currently existing metabolic and immune interrelationships between adipose and muscular tissue given by glutamine, exercise-derived myokines, and other cytokines produced by these tissues.

    A case of occult breast cancer with pseudothrombocytopenia (PTCP) is reported. A 50-year-old woman was consulted with a left axillary tumor. Ductal carcinoma was found by the core needle biopsy, and no primary lesion was detected. Her preoperative platelet count, obtained from an ethylene diamine tetraacetic acid (EDTA) sampling bottle, was 3.1 x 10(4) per mL, but she had no history of bleeding problems. A heparinized blood sample showed a normal platelet count of 390 x 10(4) per mL. These findings suggested a diagnosis of occult breast cancer with EDTA-dependent PTCP, and level II axillary lymph node dissection was performed. She received adjuvant chemotherapy and radiotherapy, but she died 2 years and 5 months after the surgery because of lung and brain metastases. Awareness of the phenomenon and knowledge of the underlying physiological principles will enable surgeons to manage patients with EDTA-dependent PTCP appropriately. PMID:20495328

    Science.gov (United States)

    This infographic shows the Breast Cancer Subtypes in Women. It’s important for guiding treatment and predicting survival. Know the Science: HR = Hormone receptor. HR+ means tumor cells have receptors for the hormones estrogen or progesterone, which can promote the growth of HR+ tumors. Hormone therapies like tamoxifen can be used to treat HR+ tumors. HER2 = Human epidermal growth Factor receptor, HER2+ means tumor cells overexpress (make high levels of) a protein, called HE2/neu, which has been shown to be associated with certain aggressive types of breast cancer. Trastuzumab and some other therapies can target cells that overexpress HER2. HR+/HER2, aka “LuminalA”. 73% of all breast cancer cases: best prognosis, most common subtype for every race, age, and poverty level. HR-/HER2, aka “Triple Negative”: 13% of all breast cancer cases, Worst prognosis, Non-Hispanic blacks have the highest rate of this subtype at every age and poverty level. HR+/HER2+, aka “Luminal B”, 10% of all breast cancer cases, little geographic variation by state. HR-/HER2+, aka”HER2-enriched”, 5% of all breast cancer cases, lowest rates for all races and ethnicities. www.cancer.gov Source: Special section of the Annual Report to the Nation on the Status of Cancer, 1975-2011.

    International Nuclear Information System (INIS)

    Breast cancer is the leading cause of cancer deaths in Ghanaian women.To describes the characteristics of breast cancer patients attending the Komfo Anokye Teaching Hospital in Kumasi, Ghana.The study was conducted at the Komfo Anokye Teaching Hospital. Between July 1st 2004 and June 30th 2009 patients presenting with breast lumps were assessed by clinical examination, imaging studies and pathological examination. Relevant clinical and pathological were recorded prospectively data on all patients with microscopically proven breast cancer. The cancers were graded according to the modified Bloom-Richardson system. Tissue immunoperoxidase stains for oestrogen, progesterone receptors and c-erb2 oncogene were performed with commercially prepared antigens and reagents.Nineteen thousand four hundred and twenty – three (19,423) patients were seen during the study period. There were 330 (1.7%) patients with histologically proven breast cancer. The mean age was 49.1 years. A palpable breast lump was detected in 248 patients (75.2%). Two hundred and eighty –one patients (85.2%) presented with Stages III and IV , 271 (82.1%) invasive and 230 ( 85.2%) high grade carcinomas. Oestrogen and progesterone receptors were positive in 32 and 9 cases respectively. Her2 protein was positive in 11 cases. In Kumasi, as in other parts of Ghana, breast cancer affects mostly young pre-menopausal who present with advanced disease. The cancers have unfavourable prognostic features and are unlikely to respond to hormonal therapy. (au)

    Background: The proportion of node-negative breast cancer patients has been increasing with improvement of diagnostic modalities and early detection. However, there is a 20–30% recurrence in node-negative breast cancers. Determining who should receive adjuvant therapy is challenging, as the majority are cured by surgery alone. Hence, it requires further stratification using additional prognostic and predictive factors. Subjects and Methods: Ours is a single institution retrospective study, on 300 node-negative breast cancer cases, who underwent primary surgery over a period of 7 years (2005–2011). We excluded all cases who took NACT. Prognostic factors of age, size, lymphovascular emboli, estrogen receptor (ER), progesterone receptor (PR), HER2neu Ki-67, grade and molecular classification were analyzed with respect to those with and without early events (recurrence, metastases or second malignancy, death) using-Pearson Chi-square method and logistic regression method for statistical analysis. Results: Majority belonged to the age group of 50–70 years. On univariate analysis, size >5 cm (P = 0.03) and ER negativity had significant association (P = 0.05) for early failures; PR negativity and lymphovascular emboli (LVE) had borderline significance (P = 0.07). Multivariate analysis showed size >5 cm to be significant (P = 0.04) and LVE positivity showed borderline significant association (P = 0.07) with early failures. About 62% belonged to luminal category followed by basal-like (25%) in molecular classification. Conclusions: ER negativity, PR negativity, LVE/lymphovascular invasion positivity and size >5 cm (T3 and T4) are associated with poor prognosis in node-negative breast cancers. PMID:26981506

    The associations of SNPs in TOX3 gene with breast cancer risk were investigated by some Genome-wide association studies and epidemiological studies, but the study results were contradictory. To derive a more precise estimate of the associations, we conducted a meta-analysis. ORs with 95% CI were used to assess the strength of association between TOX3 polymorphisms and breast cancer risk in fixed or random effect model. A total of 37 publications with 97275 cases and 128686 controls were identified. We observed that the rs3803662 C > T, rs12443621 A > G and rs8051542 C > T were all correlated with increased risk of breast cancer. In the stratified analyses by ethnicity, significantly elevated risk was detected for all genetic models of the three SNPs in Caucasians. In Asian populations, there were significant associations of rs3803662 and rs8051542 with breast cancer risk. Whereas there was no evidence for statistical significant association between the three SNPs and breast cancer risk in Africans. Additionally, we observed different associations of rs3803662 with breast cancer risk based on different ER subtype and BRCA1/BRCA2 mutation carriers. In conclusion, the meta-analysis suggested that three SNPs in TOX3 were significantly associated with breast cancer risk in different populations.

    Abstract Background Pesticides are widely used in households to control insects and weeds. Several studies, over the past decades, have examined the possible relationship of serum concentration of organochlorine pesticides and the development of breast cancer. However, little data exists regarding an association between self-reported, residential exposure to pesticides and breast cancer risk. We, therefore, present a case-control study examining self-reported exposure to household pesticides ...

    A 54-year-old woman underwent conserving surgery for right breast cancer, and received a cumulative dose of 50 Gy of radiation therapy to the remaining part of the right breast. About five months after the termination of irradiation, cough and low-grade fever developed. The chest radiograph showed an infiltrative shadow in the right lung field. Organizing pneumonia was identified in the transbronchial lung biopsy specimen. After prednisolone was given to the patient the clinical symptoms and infiltrates seen in the radiograph disappeared. In the course of tapering the prednisolone dose, new infiltrative shadows developed in the upper right lung and the left lung. The histologic changes were shown by transbronchial lung biopsy to be organizing pneumonia. The increased dose of prednisolone resulted in the rapid improvement of the clinical symptoms and chest radiograph abnormalities. This case suggests that breast radiation after conserving surgery for breast cancer may cause a pathologic process similar to that of bronchiolitis obliterans organizing pneumonia. (author)

    Since several studies have demonstrated the inadequate diagnostic performance of mammography in high risk women, over the past two decades, different breast imaging tests have been evaluated as additional diagnostic methods to mammography, and the most relevant ones are the techniques that do not imply the use of X-rays, considering the young age of these patients and the higher radio-sensitivity. Breast dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) has risen growing interest not only because of the absence of use of X-rays, but also because it provides morpho-functional features, which may depict biological characteristics of breast tissues, including invasive and in situ cancers. Different multicenter non-randomized prospective studies aimed to evaluate breast DCE-MRI as an integral part of surveillance programs, agreed about the evidence that in high risk women screening with DCE-MRI is more effective than either mammography and/or ultrasound. Moreover, this modality leads to the identifications of cancers at a more favorable stage, allowing a real advantage in terms of tumor size and nodal involvement. The medical community is evaluating to suggest DCE-MRI alone as screening modality in high-risk women, as it was reported that in these cases the sensitivity of MRI plus conventional imaging was not significantly higher than that of MRI alone. Breast MRI is now recommended as part of screening program for high risk women by both European and American guidelines. PMID:26924173

    Full Text Available Abstract Background Older paternal age may increase the germ cell mutation rate in the offspring. Maternal age may also mediate in utero exposure to pregnancy hormones in the offspring. To evaluate the association between paternal and maternal age at birth with the risk of breast cancer in female offspring, a case-control study was conducted in Korea. Methods Histologically confirmed breast cancer cases (n = 1,011 and controls (n = 1,011 with no present or previous history of cancer, matched on year of birth and menopausal status, were selected from several teaching hospitals and community in Seoul during 1995–2003. Information on paternal and maternal ages and other factors was collected by interviewed questionnaire. Odds ratio (OR and 95% confidence interval (95% CI were estimated by unconditional logistic regression model adjusting for family history of breast cancer in 1st or 2nd degree relatives, and lifetime estrogen exposure duration. Results The risk of breast cancer significantly increased as the paternal age increased (p for trend = 0.025. The association was stronger after controlling for maternal age; women whose fathers were aged ≥40 years at their birth had 1.6-fold increased risk of breast cancer compared with fathers aged Conclusion These findings suggest that older paternal age increases the risk of breast cancer in their female offspring.

    Older adults are underrepresented in medical research for many reasons, including recruitment difficulties. Recruitment of older adults for research studies is often a time-consuming process and can be more challenging when the study involves older adults with unique exposures to traumatic events and from minority groups. The current article provides a brief overview of (a) challenges encountered while recruiting aging women Holocaust survivors for a case control study and (b) strategies used for meeting those challenges. The case group comprised women Holocaust survivors who were recently diagnosed with breast cancer and the control group comprised healthy women from a Holocaust-survivor community in Israel.

    Breast cancer is a leading cause of cancer-related deaths in women worldwide. Although tumorectomy,radiotherapy, chemotherapy and hormone replacement therapy have been used for the treatment of breast cancer, there is no effective therapy for patients with invasive and metastatic breast cancer. Immunotherapy may be proved effective in treating patients with advanced breast cancer. Breast cancer immunotherapy includes antibody based immunotherapy, cancer vaccine immunotherapy, adoptive T cell transfer immunotherapy and T cell receptor gene transfer immunotherapy. Antibody based immunotherapy such as the monoclonal antibody against HER-2/neu (trastuzumab) is successfully used in the treatment of breast cancer patients with over-expressed HER-2/neu, however, HER-2/neu is over-expressed only in 25-30% of breast cancer patients. Cancer vaccine immunotherapy is a promising method to treat cancer patients. Cancer vaccines can be used to induce specific anti-tumor immunity in breast cancer patients, but cannot induce objective tumor regression. Adoptive T cell transfer immunotherapy is an effective method in the treatment of melanoma patients. Recent advances in anti-tumor T cell generation ex vivo and limited clinical trial data have made the feasibility of adoptive T cell transfer immunotherapy in the treatment of breast cancer patients. T cell receptor gene transfer can redirect the specificity of T cells. Chimeric receptor, scFv(anti-HER-2/neu)/zeta receptor, was successfully used to redirect cytotoxic T lymphocyte hybridoma cells to obtain anti-HER-2/neu positive tumor cells, suggesting the feasibility of treatment of breast cancer patients with T cell receptor gene transfer immunotherapy. Clinical trials will approve that immunotherapy is an effective method to cure breast cancer disease in the near future.

    We encountered a case of occult contralateral breast cancer, previously undetected by conventional imaging such as mammography (MMG) and ultrasonography (US), but incidentally detected by contrast-enhanced magnetic resonance imaging (CE-MRI). We present it here with a review of the literature. A 67-year-old Japanese woman was referred to our hospital in October 2000 because of a 1.5 cm right breast lump detected in a medical checkup. MMG, US and fine needle aspiration cytology revealed a cancerous lesion during the right breast. No mass lesion was palpable nor was any detected by MMG or US in the left breast. Bilateral breast CE-MRI was performed for more detailed evaluation. Consequently, an occult contralateral breast cancerous lesion was detected incidentally by CE-MRI, with the images showing rapid initial enhancement of time to signal intensity curves. Before surgery, bilateral breast lesions were diagnosed as invasive ductal carcinoma by open biopsy. She underwent bilateral breast conserving surgery with bilateral axillary lymph node dissection. The postoperative course was uneventful and no recurrence has been noted as of January 18th, 2004. CE-MRI of the contralateral breast should be of value as a routine screen in those patients with a known or suspected malignancy in one breast considering the limits of breast cancer detection by such conventional modalities as MMG and US.

    Full Text Available Background: Clinical, animal, and epidemiological studies have clearly demonstrated that cancer is a hormonally mediated disease and several factors that influence hormonal status or are markers of change in hormonal status have been shown to be associated with the risk of breast cancer. Aims: To identify the association of various reproductive factors with breast cancer. Settings and Design: A hospital-based, matched, case-control study. Materials and Methods: Three hundred and twenty newly diagnosed breast cancer cases and three hundred and twenty normal healthy individuals constituted the study population. The subjects in the control group were matched individually with the cases for their age ± 2 years and socioeconomic status. A pre-tested, semi-structured questionnaire was administered to each individual to collect information on identification data, socio-demographic profile, and reproductive factors. Statistical Analysis Used: The Chi-square test and unpaired t-test were used. The conditional univariate logistic regression analysis (unadjusted odds ratio and confidence intervals was used to calculate the significance level of each variable followed by multivariate regression analysis. Results and Conclusions: The cases had a lower mean age at menarche, higher age at marriage, higher mean age at last child birth, lower mean duration of breastfeeding, higher number of abortions, late age at menopause, history of oral contraceptive pills, and a family history of breast cancer as compared to the controls. The results of the present study revealed a strong association of reproductive factors with breast cancer in the Indian population.

    Full Text Available Abstract Background In Taiwan, there is a high incidence of breast cancer and a high prevalence of viral hepatitis. In this case-control study, we used a population-based insurance dataset to evaluate whether breast cancer in women is associated with chronic viral hepatitis infection. Methods From the claims data, we identified 1,958 patients with newly diagnosed breast cancer during the period 2000-2008. A randomly selected, age-matched cohort of 7,832 subjects without cancer was selected for comparison. Multivariable logistic regression models were constructed to calculate odds ratios of breast cancer associated with viral hepatitis after adjustment for age, residential area, occupation, urbanization, and income. The age-specific ( Results There were no significant differences in the prevalence of hepatitis C virus (HCV infection, hepatitis B virus (HBV, or the prevalence of combined HBC/HBV infection between breast cancer patients and control subjects (p = 0.48. Multivariable logistic regression analysis, however, revealed that age Conclusions HCV infection, but not HBV infection, appears to be associated with early onset risk of breast cancer in areas endemic for HCV and HBV. This finding needs to be replicated in further studies.

  19. Frequency of the ATM IVS10-6T→G variant in Australian multiple-case breast cancer families

    International Nuclear Information System (INIS)

    Germline mutations in the genes BRCA1 and BRCA2 account for only a proportion of hereditary breast cancer, suggesting that additional genes contribute to hereditary breast cancer. Recently a heterozygous variant in the ataxia–telangiectasia mutated (ATM) gene, IVS10-6T→G, was reported by an Australian multiple-case breast cancer family cohort study (the Kathleen Cuningham Foundation Consortium for Research into Familial Breast Cancer) to confer a substantial breast cancer risk. Although this variant can result in a truncated ATM product, its clinical significance as a high-penetrance breast cancer allele or its role as a low-penetrance risk-modifier is controversial. We determined the frequency of ATM IVS10-6T→G variants in a cohort of individuals affected by breast and/or ovarian cancer who underwent BRCA1 and BRCA2 genetic testing at four major Australian familial cancer clinics. Seven of 495 patients (1.4%) were heterozygous for the IVS10-6T→G variant; the carrier rate in unselected Australian women with no family history of breast cancer is reported to be 6 of 725 (0.83%) (P = 0.4). Two of the seven probands also harboured a pathogenic BRCA1 mutation and one patient had a BRCA1 unclassified variant of uncertain significance. These findings indicate that the ATM IVS10-6T→G variant does not seem to occur at a significantly higher frequency in affected individuals from high-risk families than in the general population. A role for this variant as a low-penetrance allele or as a modifying gene in association with other genes (such as BRCA1) remains possible. Routine testing for ATM IVS10-6T→G is not warranted in mutation screening of affected individuals from high-risk families

    Ten patients with endobronchial metastasis from primary breast cancer were found among 1200 fibreoptic bronchoscopies. Six of these patients had radiological signs suggesting bronchial obstruction. The diagnosis was verified in nine cases by means of bronchoscopic biopsy or cytology and in one by thoracotomy. Endobronchial metastasis should be considered when symptoms or chest films suggest endobronchial disease in a patient with a history of breast cancer.

    Familial breast cancer is important because of all the known risk factors associated with developing the disease. The one with the most predictability is a positive family history. It is also important because a family history causes anxiety in the families concerned, and young women will often ask their chance of developing the disease. This form of breast cancer accounts for 10% of causes and has factors that distinguish it from the sporadic variety. Relatives of familial breast cancer pati...

    Full Text Available Abstract Background Previous epidemiological studies have inconsistently shown a modestly increased breast cancer risk associated with hormone replacement therapy (HRT. Limited information is available about different formulations – particularly concerning different progestins. Methods A case-control study was performed within Germany in collaboration with regional cancer registries and tumor centers. Up to 5 controls were matched breast cancer cases. Conditional logistic regression analysis was applied to estimate crude and adjusted odds ratios (OR and 95% confidence intervals (95% CI. Stratified analyses were performed to compare the risk of different estrogens, progestins, and combinations. Results A total of 3593 cases of breast cancer were identified and compared with 9098 controls. The adjusted overall risk estimate for breast cancer (BC associated with current or past use of HRT was 1.2 (1.1–1.3, and almost identical for lag times from 6 months to 6 years prior to diagnosis. No significant trend of increasing BC risk was found with increasing duration of HRT use, or time since first or last use in aggregate. Many established BC risk factors significantly modified the effect of HRT on BC risk, particularly first-degree family history of BC, higher age, lower education, higher body mass index (BMI, and never having used oral contraceptives (OCs during lifetime. Whereas the overall risk estimates were stable, the numbers in many of the sub-analyses of HRT formulation groups (estrogens, progestins, and combinations were too small for strong conclusions. Nevertheless, the BC risk seems not to vary much across HRT formulation subgroups. In particular, no substantial difference in BC risk was observed between HRT containing conjugated equine estrogens (CEE or medroxyprogesterone acetate (MPA and other formulations more common in Europe. Conclusion The BC risk of HRT use is rather small. Low risk estimates for BC and a high potential for

    We are investigating the feasibility of improving breast cancer risk prediction by computerized mammographic parenchymal pattern (MPP) analysis. A case-control study was conducted to investigate the association of the MPP measures with breast cancer risk. The case group included 168 contralateral CC-view mammograms of breast cancer patients dated at least one year prior to cancer diagnosis, and the control group included 522 CC-view mammograms from one breast of normal subjects. We extracted and compared four types of statistical texture feature spaces that included run length statistics and region size statistics (RLS/RSS) features, spatial gray level dependence (SGLD) features, gray level difference statistics (GLDS) features, and the feature space combining these three types of texture features. A linear discriminant analysis (LDA) classifier with stepwise feature selection was trained and tested with leave-one-case-out resampling to evaluate whether the breast parenchyma of future cancer patients could be distinguished from those of normal subjects in each feature space. The areas under ROC curves (Az) were 0.71, 0.72, 0.71 and 0.76 for the four feature spaces, respectively. The Az obtained from the combined feature space was significantly (pbreast cancer risk and four categories of MPP measures: 0.2 (C4) while patient age was treated as a confounding factor. The adjusted ORs of breast cancer for C2, C3 and C4 were 3.23, 7.77 and 25.43, respectively. The preliminary result indicated that our proposed computerized MPP measures were strongly associated with breast cancer risk.

    A case-control study of the role of diet in the etiology of breast cancer was conducted in Athens, Greece. There are reasons to believe that the diet of the Greek population is characterized by greater heterogeneity than that in most countries where such studies have been undertaken. The case series consisted of 120 consecutive patients with histologically confirmed breast cancer admitted to either of two teaching hospitals over a 12-month period. The controls were 120 patients admitted to a teaching hospital for trauma and orthopedic conditions during the same period. Dietary histories concerning the frequency of consumption of 120 foods and drinks were obtained by interview. Cases reported significantly less frequent consumption of vegetables as a group and, within that group, specifically of cucumber, lettuce and raw carrot. After adjustment for potential external confounding variables and for confounding between food categories, the odds ratio for persons in the highest quintile of vegetable consumers, relative to those in the lowest quintile, was 0.09 with 95% confidence limits 0.03-0.30. That is to say, the lowest quintile of vegetable consumers had about 10 times the breast cancer risk of the highest quintile. For a score based on consumption of only the 3 specified salad items the odds ratio over the extreme quartiles was 0.12 (0.05-0.32). There was no association with consumption of fats and oils, alcohol or coffee, and no significant association with any other major food category (including alcohol and coffee) after adjustment for confounding variables.

    Sarcoidosis is a benign systematic granulomatous disorder of unknown etiology and is associated with various malignancies. However, granulomatous and metastatic lymph node lesions are difficult to distinguish even when using precise and modern diagnostic methods, such as positron emission tomography. Thus, histological verification is the only method that can be used to accurately describe the nature of this disease. In this article, we report a case of non-luminal HER-2/neu-positive breast cancer in a patient without history of sarcoidosis and suspected to have metastatic disease.

Eleven months after radiation, magnetic resonance imaging showed diffuse leukoencephalopathy. Twenty-two months after radiation, the patient had gait disturbance, parkinsonism, dementia and urinary incontinence. From this experience, stereotactic radiosurgery such as cyber knife and gamma knife therapy, representing a new modality for delivering intense focal radiation, should be come preferred techniques for treating patients with brain metastases, to avoid the potential cognitive side effects of fractionated whole-brain radiotherapy.

    Full Text Available Abstract Background Pesticides are widely used in households to control insects and weeds. Several studies, over the past decades, have examined the possible relationship of serum concentration of organochlorine pesticides and the development of breast cancer. However, little data exists regarding an association between self-reported, residential exposure to pesticides and breast cancer risk. We, therefore, present a case-control study examining self-reported exposure to household pesticides with regard to associated risk of breast cancer. Methods This study was conducted in the area in and around New York City, NY and included 1205 patients (447 cases and 758 controls. Cases were defined as women with newly diagnosed breast cancer or carcinoma in-situ, while controls included women with benign breast diseases or those undergoing non-breast related surgery. All patients were asked a series of questions to determine their pesticide exposure, including the type of pesticide, location of exposure (inside vs. outside the home, who applied the pesticide (self vs. a professional and duration of pesticide use. Logistic regression models were used to estimate unadjusted and adjusted odds ratios (OR and corresponding 95% confidence intervals (CI. Results The most common pests encountered in participants' homes were ants, carpenter ants, and cockroaches. The calculated adjusted odds ratios for both self and professionally applied pesticides, specifically against the above mentioned insects, with regard to breast cancer risk were 1.25 (95% CI: 0.79-1.98 and 1.06 (95% CI: 0.65-1.73, respectively. Similarly, odds ratios and confidence intervals were calculated for other types of pesticides. Conclusions Overall, the results of our study did not show an association between self-reported exposure to pesticides and breast cancer risk. Future studies, utilizing a larger sample size and more specific detail on time frame of pesticide exposure, are needed to

    To evaluate the mammographic and clinical features of bilateral breast cancer. We retrospectively reviewed clinical records(n=23) and mammograms (n=15) of 23 patients with bilateral breast cancer. Patients' age, location of the tumor and pathologic staging were determined from clinical records. Mammographic features were classified as spiculated mass, nonspiculated mass, mass with microcalcification, microcalcification only, asymmetric density, and normal. Of the 23 cases of bilateral breast cancer, 8(34.8%) were synchronous and 15(65.2%) were metachronous. Age at diagnosis of cancer in the first breast was between 27 and 59(mean 43) years ; there was no statistically significant difference in mean age between patients with synchronous and metachronous cancer. The mean interval between the diagnosis of each lesion of the metachronous pairs was 9.1 years. In 11 of 23 cases(48%), tumors were locaated in the same quadrant, and in the other 12 cases(52%), they were in different quadrant. At mammography, five of 15 metachronous cancers(33%) were similar in appearance and 10 pairs(67%) were different. In 4 of 23 cases(17%), cancer in the first breast was at stage 0 and stage 1, and in 13 of 23(57%), cancer in the second breast was at this same stage. In bilateral breast cancer, the two breasts frequently show different mammographic features. Cancer of the second breast was at an early stage; this suggest that regular examination and mammography are important and can allow early detection of contralateral breast cancer.

    2011-10-01

    Full Text Available Abstract Background Breast cancer (BC is the most common cancer for women in the western world. From very few cases an extraordinary increase in BC was observed in the Inuit population of Greenland and Canada although still lower than in western populations. Previous data suggest that exposure to persistent organic pollutants (POPs might contribute to the risk of BC. Rat studies showed that perfluorinated compounds (PFCs cause significantly increase in mammary fibroadenomas. This study aimed at evaluating the association between serum levels of POPs/PFCs in Greenlandic Inuit BC cases and their controls, and whether the combined POP related effect on nuclear hormone receptors affect BC risk. Methods Thirty-one BC cases and 115 controls were sampled during 2000-2003 from various Greenlandic districts. The serum levels of POPs, PFCs, some metals and the combined serum POP related effect on estrogen- (ER, androgen- (AR and Ah-receptor (AhR transactivity were determined. Independent student t-test was used to compare the differences and the odds ratios were estimated by unconditional logistic regression models. Results We observed for the very first time a significant association between serum PFC levels and the risk of BC. The BC cases also showed a significantly higher concentration of polychlorinated biphenyls at the highest quartile. Also for the combined serum POP induced agonistic AR transactivity significant association to BC risk was found, and cases elicited a higher frequency of samples with significant POP related hormone-like agonistic ER transactivity. The AhR toxic equivalent was lowest in cases. Conclusions The level of serum POPs, particularly PFCs, might be risk factors in the development of BC in Inuit. Hormone disruption by the combined serum POP related xenoestrogenic and xenoandrogenic activities may contribute to the risk of developing breast cancer in Inuit. Further investigations are needed to document these study conclusions.

    International Nuclear Information System (INIS)

    This retrospective analysis was performed to evaluate osteolytic bone lesions of breast cancer in the thoracic and lumbar spine after radiotherapy (RT) in terms of stability using a validated scoring system. The stability of 157 osteolytic metastases, treated from January 2000 to January 2012, in 115 patients with breast cancer was evaluated retrospectively using the Taneichi score. Predictive factors for stability were analyzed and survival rates were calculated. Eighty-five (54 %) lesions were classified as unstable prior to RT. After 3 and 6 months, 109 (70 %) and 124 (79 %) lesions, respectively, were classified as stable. Thirty fractures were detected prior to RT, and after RT seven cases (4.5 %) with pathologic fractures were found within 6 months. None of the examined predictive factors showed significant correlation with stability 6 months after RT. After a median follow-up of 16.7 months, Kaplan-Meier estimates revealed an overall survival of 83 % after 5 years. The majority of patients showed an improved or unchanged stability of the involved vertebral bodies after 6 months. The patients showed only minor cancer-related morbidity during follow-up and reached comparably high survival rates. (orig.)

    Breast cancer is the most common malignancy among women in the Western society. Over the past decades it has become apparent that breast cancer incidence rates are increasing steadily, whereas the mortality rates for breast cancer have remained relatively constant. Information through the media on this rising number of cases has increased breast health awareness but has also introduced anxiety in the female population. This combination of factors has made the need for prevention of breast cancer an urgent matter. Breast cancer does not seem to be a single disease entity. A specific etiologic factor may therefore have more influence on one form may therefore have more influence on one form of breast cancer than another. So far though, as shown in their summary of current knowledge on established and dubious risk factors, no risk factors have been identified that can explain a major part of the incidence. Efforts to identify other ways for primary prevention have also been discouraging, even though breast cancer is one of the most investigated tumours world-wide. Thus, at this point i time, the most important strategy to reduce breast cancer mortality is early detection through individual counselling and organised breast screening programs. The recent isolation of breast cancer susceptibility genes may introduce new ways to reduce the risk of breast cancer in a small subset of women.

  5. Contralateral breast cancer risk

    International Nuclear Information System (INIS)

    The use of breast-conserving treatment approaches for breast cancer has now become a standard option for early stage disease. Numerous randomized studies have shown medical equivalence when mastectomy is compared to lumpectomy followed by radiotherapy for the local management of this common problem. With an increased emphasis on patient involvement in the therapeutic decision making process, it is important to identify and quantify any unforeseen risks of the conservation approach. One concern that has been raised is the question of radiation- related contralateral breast cancer after breast radiotherapy. Although most studies do not show statistically significant evidence that patients treated with breast radiotherapy are at increased risk of developing contralateral breast cancer when compared to control groups treated with mastectomy alone, there are clear data showing the amount of scattered radiation absorbed by the contralateral breast during a routine course of breast radiotherapy is considerable (several Gy) and is therefore within the range where one might be concerned about radiogenic contralateral tumors. While radiation related risks of contralateral breast cancer appear to be small enough to be statistically insignificant for the majority of patients, there may exist a smaller subset which, for genetic or environmental reasons, is at special risk for scatter related second tumors. If such a group could be predicted, it would seem appropriate to offer either special counselling or special prevention procedures aimed at mitigating this second tumor risk. The use of genetic testing, detailed analysis of breast cancer family history, and the identification of patients who acquired their first breast cancer at a very early age may all be candidate screening procedures useful in identifying such at- risk groups. Since some risk mitigation strategies are convenient and easy to utilize, it makes sense to follow the classic 'ALARA' (as low as reasonably

We present the results obtained with a prototype of a new mini gamma camera developed especially for the operative lymphoscintigraphy of the axillary area in case of breast cancer. This prototype is composed of 10 mm thick parallel lead collimator, a 2 mm thick GSO:Ce inorganic scintillating crystal from Hitachi and a Hamamatsu H8500 flat panel multianode (64 channels) photomultiplier tube (MAPMT) equipped with a dedicated electronics. Its actual field of view is 50 × 50mm2. The gamma interaction position in the GSO scintillating plate is obtained by calculating the center of gravity of the fired MAPMT channels. The measurements performed with this prototype demonstrate the usefulness of this mini gamma camer...

  8. Eleven cases of breast scirrhous carcinoma with a diameter of one centimeter or less detected by breast cancer screening

    International Nuclear Information System (INIS)

    Clinical, imaging, and histopathological characteristics were examined for breast scirrhous carcinoma with diameters of 1 cm or less detected by breast cancer screening. At our institution, screening includes palpation and mammography as well as ultrasound examinations of all patients. Single lesions were discovered by mammography in 3 patients and by ultrasound in 8 patients. None of the lesions were palpable. Lesions were detected by mammography in 3 patients. However, lesions were detected by ultrasound in all patients. On ultrasound, 82% of findings showed a mass. MRI was performed for 7 patients and demonstructed all of the lesions. In these patient so diagnoses by fine needle aspiration cytology were malignant lesions or lesions suspicious of malignancy in 55% of the patients. Histopathologically, 91% were nuclear grade 1, positive for hormone receptors, and negative for HER2. Breast scirrhous carcinoma with diameters of 1 cm or less detected by breast cancer screening were mostly detected by ultrasound and showed good prognosis. (author)

    The level of total adiponectin, a mixture of different adiponectin forms, has been reported associated with breast cancer risk with inconsistent results. Whether the different forms play different roles in breast cancer risk prediction is unclear. To examine this, we measured total and high molecular weight (HMW) adiponectin in a case-control study (1167 sets). Higher circulating HMW adiponectin was negatively associated with breast cancer risk after adjusting for menopausal status and family...

    One thousand, four hundred and forty-six patients with carcinoma of the breast treated with Halsted mastectomy (167), Patey mastectomy (732), and conservative surgery with axillary dissection, either at the same time (340), or separately (207), were evaluated with regard to the number and distribution of axillary lymph nodes. A total of 29,378 were removed and examined, on average 20.3 per patient. The average number of nodes was 13.5 at the first level, 4.5 at the second and 2.3 at the third. The same number of nodes were removed in patients treated with extensive surgery, such as Halsted mastectomy and limited surgery such as lumpectomy and in independent axillary dissection. In 839 cases metastases were found in the axilla. The average number of involved nodes was 6.4. Out of 839 patients, the first level was the site of metastases in 828, the second level in 364 and the third in 187. When a single lymph node was involved, it was nearly always at the first level. In only 11 cases, were the second and/or third levels invaded without metastases at the first level. Therefore, the percentage of cases with skipping metastases was very low (1.3%). It appears from the present data that the spread of breast cancer to the axilla follows a regular pattern; the first level is invaded first, whilst in most cases, the second and third levels are involved only when the first is substantially affected.

    In breast cancer, radiotherapy is an essential component of the treatment. After conservative surgery for an infiltrating carcinoma, radiotherapy must be systematically performed, regardless of the characteristics of the disease, because it decreases the rate of local recurrence and by this way, specific mortality. Partial breast irradiation could not be proposed routinely but only in very selected and informed patients. For ductal carcinoma in situ, adjuvant radiotherapy must be also systematically performed after lumpectomy. After mastectomy, chest wall irradiation is required for pT3-T4 tumours and if there is an axillary nodal involvement, whatever the number of involved lymph nodes. After neo-adjuvant chemotherapy and mastectomy, in case of pN0 disease, chest wall irradiation is recommended if there is a clinically or radiologically T3-T4 or node positive disease before chemotherapy. Axillary irradiation is recommended only if there is no axillary surgical dissection and a positive sentinel lymph node. Supra and infra-clavicular irradiation is advised in case of positive axillary nodes. Internal mammary irradiation must be discussed case by case, according to the benefit/risk ratio (cardiac toxicity). Dose to the chest wall or the breast must be between 45-50Gy with a conventional fractionation. A boost dose over the tumour bed is required if the patient is younger than 60 years old. Hypofractionation (42.5 Gy in 16 fractions, or 41.6 Gy en 13 or 40 Gy en 15) is possible after tumorectomy and if a nodal irradiation is not mandatory. Delineation of the breast, the chest wall and the nodal areas are based on clinical and radiological evaluations. 3D-conformal irradiation is the recommended technique, intensity-modulated radiotherapy must be proposed only in case of specific clinical situations. Respiratory gating could be useful to decrease the cardiac dose. Concomitant administration of chemotherapy in unadvised, but hormonal treatment could be start with

    Male breast cancer, which represents only 1% of all breast cancers, is occasionally associated with a family history of breast cancer. Sporadic male breast cancers presenting with another primary breast cancer are extremely rare. In this article, we report on a 70-year-old male patient with bilateral multifocal and synchronous breast cancer and without a family history of breast cancer.

    Phosphatidylinositol-3-kinase (PI3K) is a group of enzymes involved in cellular growth, proliferation, differentiation, cell motility, intracellular trafficking, and survival that play very important roles in developing breast cancer. PIK3CA is a gene that encodes α catalytic subunit of this enzyme. A common polymorphism of PIK3CA, rs7640662 (C/G), was analyzed, and its association to breast cancer cases was determined. In this study, DNA was extracted from peripheral blood samples of 278 women suffering from breast cancer and 128 healthy women. Tetra-primer amplification refractory mutation system polymerase chain reaction (T-ARMS-PCR) method was performed to genotype rs7640662. P values and ODD ratios were measured using SPSS. P value less than 0.05 and ODD ratios more than 1 were considered as significant. All ODD ratios were less than 1, and P values were more than 0.05 showing that rs7640662 (C/G) and breast cancer are not significantly associated. However, the genotypes observed in the Persian population, as an ancient population living in the Middle East, was significantly different from the genotypes reported by HapMap for Asian populations. As a conclusion, rs7640662 was not associated with the risk of breast cancer in a Persian population; however, it was observed that heterozygote (GC) is the most common genotypes in both case and control samples.

    Full Text Available Abstract For head and neck as well as for oromaxillofacial surgery, the use of the pectoralis major myocutaneous (PMMC flap is a standard reconstructive technique after radical surgery for cancers in this region. We report to our knowledge for the first development of breast cancer in the PMMC flap in a 79 year old patient, who had undergone several operations in the past for recurring squamous cell carcinoma of the jaw. The occurrence of a secondary malignancy within the donor tissue after flap transfer is rare, but especially in the case of transferred breast tissue and the currently high incidence of breast cancer theoretically possible. Therefore preoperative screening mammography seems advisable to exclude a preexisting breast cancer in female patients undergoing such reconstruction surgery. Therapy for breast cancer under these circumstances is individual and consists of radical tumor resection followed by radiation if applicable and a standard systemic therapeutic regimen on the background of the patients individual prognosis due to the primary cancer.

    Overweight or obese women are at increased risk of developing and dying from breast cancer. Obesity-driven inflammation may stimulate prostaglandin E2 (PGE2)-mediated aromatase activation and estrogen biosynthesis in breast tissues. We hypothesized that increased production of PGE2 would contribute to elevated breast cancer risk in postmenopausal women. We carried out a case-cohort study with 307 incident breast cancer cases and 300 subcohort members from the Sister Study cohort. HRs and 95% confidence intervals (CI) were estimated for the association between urinary levels of a major PGE2 metabolite (PGE-M) and breast cancer risk using Prentice's pseudo-likelihood approach. Several lifestyle factors were associated with urinary levels of PGE-M: smoking, high-saturated fat diet, and obesity increased urinary PGE-M, and use of nonsteroidal antiinflammatory drugs (NSAID) decreased urinary PGE-M. Although there was no association between urinary PGE-M and postmenopausal breast cancer risk in the overall analysis or among regular users of NSAIDs, there was a positive association among postmenopausal women who did not regularly use NSAIDs with HRs of 2.1 [95% confidence interval (CI): 1.0-4.3]; 2.0 (95% CI: 1.0-3.9); and 2.2 (95% CI: 1.1-4.3) for the second, third, and highest quartiles of PGE-M. Our findings suggest a link between systemic PGE2 formation and postmenopausal breast cancer, and a possible modification of the association by lifestyle and pharmacologic interventions. If confirmed in larger studies, these results may have useful implications for the development of preventive strategies. PMID:23636050

    Full Text Available Cancer metastasis, resistance to therapies and disease recurrence are significant hurdles to successful treatment of breast cancer. Identifying mechanisms by which cancer spreads, survives treatment regimes and regenerates more aggressive tumours are critical to improving patient survival. Substantial evidence gathered over the last 10 years suggests that breast cancer progression and recurrence is supported by cancer stem cells (CSCs. Understanding how CSCs form and how they contribute to the pathology of breast cancer will greatly aid the pursuit of novel therapies targeted at eliminating these cells. This review will summarise what is currently known about the origins of breast CSCs, their role in disease progression and ways in which they may be targeted therapeutically.

    Full Text Available Abstract Background Breast cancer is one of the major public health problems among women worldwide. A number of epidemiological studies have been carried out to find the role of dietary fat and the risk of breast cancer. The main objective of the present communication is to summarize the evidence from various case-control and cohort studies on the consumption of fat and its subtypes and their effect on the development of breast cancer. Methods A Pubmed search for literature on the consumption of dietary fat and risk of breast cancer published from January 1990 through December 2003 was carried out. Results Increased consumption of total fat and saturated fat were found to be positively associated with the development of breast cancer. Even though an equivocal association was observed for the consumption of total monounsaturated fatty acids (MUFA and the risk of breast cancer, there exists an inverse association in the case of oleic acid, the most abundant MUFA. A moderate inverse association between consumption of n-3 fatty acids and breast cancer risk and a moderate positive association between n-6 fatty acids and breast cancer risk were observed. Conclusion Even though all epidemiological studies do not provide a strong positive association between the consumption of certain types of dietary fat and breast cancer risk, at least a moderate association does seem to exist and this has a number of implications in view of the fact that breast cancer is an increasing public health concern.

    The clinical and pathological characteristics and prognostic outcome of patients with hereditary breast/ovarian cancer and BRCA2 mutations are poorly known. Hence, the present study aimed to correlate the BRCA2 mutation status with clinical characteristics and overall survival of 102 breast/ovarian cancer patients in Kerala, South India. All the coding regions of BRCA2 genes were PCR amplified and analyzed for mutations employing Conformation Sensitive Gel Electrophoresis and characterized by sequencing. The ORs with 95% Cls was computed to assess the association between BRCA2 gene mutation status and clinicopathologic characteristics of breast cancer patients. Survival curves were generated according to Kaplan-Meier method using Log Rank test and Cox proportional hazards regression method. Out of the 102 breast/ovarian cancer patients with known BRCA2 status, 19 were BRCA2 mutation positive. In survival analysis, BRCA2 gene mutation status (P = 0.02) and clinicopathologic parameters such as tumour size (p = 0.01), metastasis (P = 0.01), disease stage (P = 0.03) and laterality (P = 0.02) were significantly associated with poor prognosis of breast cancer patients. Patients with hereditary breast/ovarian cancer resulting from a BRCA2 mutation have been conclusively shown to have a worse survival prognosis compared to the non mutated group of patients.

    Full Text Available Background: Primary synchronous bilateral breast cancer (PSBBC is a rare clinical entity. The reported incidence ranges between 0.3% and 12%. There are several controversial issues regarding PSBBC pertaining to the diagnostic criteria, nomenclature, and management policies. Materials and Methods: Fourteen cases of PSBBC treated between 2001 to 2010 at our institute were retrospectively analysed in regards to demographic data, management and follow up. Results: PSBBC constituted 0.19% of total breast cancer patients at our institute. Age ranged from 28 to 78 years. PSBBC were detected by clinical examination in eight cases and by mammography in six cases. Twelve patients underwent bilateral modified radical mastectomy, one had unilateral mastectomy on one side and breast conservation on the other side and one patient has bilateral breast conservation. Majority of patients belonged to stage 2 and stage 3. All patients were found to have invasive ductal carcinoma. Five cases were ER/PR positive and 8 patients were triple hormone receptor negative. Eight patients received unilateral and six received bilateral adjuvant radiotherapy. Nine patients received adjuvant chemotherapy. 5 patients received adjuvant hormonal therapy. Median follow up of patients was 15.4 months. Conclusion: PSBBC is a rare event warranting awareness and screening of the contralateral breast in patients with unilateral breast cancer. These patients require individualized treatment planning based on the tumor factors of the index lesion. Further multi institutional prospective studies are needed for adequate understanding of management of PSBBC.

  8. Evaluation of enhancement patterns using three-dimensional dynamic contrast-enhanced MR imaging in 209 cases of breast cancer

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate contrast-enhanced patterns using three-dimensional (3D) dynamic MR imaging in 209 cases of breast cancer. Three-dimensional dynamic imaging of the breast (1.5-T scanner) was performed in 755 cases. Of 227 breast carcinomas, 209 cases that were histologically confirmed were enrolled in this study. The histological diagnoses included ductal carcinoma in situ (DCIS) (n=12), invasive ductal carcinoma (n=176), mucinous carcinoma (n=10), meduliary carcinoma (n=4), invasive lobular carcinoma (n=6), and other (n=1). Tumor size was a mean 24.6 mm in diameter (range, 7-110 mm), including 110 cases of small breast carcinomas (≤2 cm). The contrast-enhancement pattern was analyzed from the early phase of 3D-MRI and the post-contrast T1-weighted spin echo (SE) image acquired before the delayed phase of 3D-MRI. The type of peripheral enhancement (PE) was evaluated on the early and delayed phases of 3D-MRI. These enhancement patterns were also compared with the histological findings of small breast carcinomas. The sensitivity of the 209 cases of breast carcinoma was 99% (207/209) on 3D dynamic MRI. Two hundred six cases (98.6%), including all DCIS, showed strong enhancement on the early phase of 3D MRI. An increased washout pattern showing signal intensity lower than that of fat on post-contrast T1-weighted imaging was noted in 201 cases (96.1%), of which 179 cases (85.6%) showed washout patterns. PE was identified in 63 cases (30.4%) and in 35 of 110 cases of small breast carcinoma (31.8%). Delayed PE following central washout was noted in 65% of 63 cases and 71.4% of 35 cases of small breast carcinoma. Delayed PE was well correlated with marginal fibrosis. Three-dimensional dynamic MRI of the breast was highly sensitive for breast carcinoma. Delayed PE following central washout was considered a specific finding of breast carcinoma. It is important to understand the enhancement patterns of 3D dynamic MRI for excellent specificity of

    Full Text Available Abstract Background Interleukins and cytokines play an important role in the pathogenesis of many solid cancers. Several single nucleotide polymorphisms (SNPs identified in cytokine genes are thought to influence the expression or function of these proteins and many have been evaluated for their role in inflammatory disease and cancer predisposition. The aim of this study was to evaluate any role of specific SNPs in the interleukin genes IL1A, IL1B, IL1RN, IL4R, IL6 and IL10 in predisposition to breast cancer susceptibility and severity. Methods Candidate single nucleotide polymorphisms (SNPs in key cytokine genes were genotyped in breast cancer patients and in appropriate healthy volunteers who were similar in age, race and sex. Genotyping was performed using a high throughput allelic discrimination method. Data on clinico-pathological details and survival were collected. A systematic review of Medline English literature was done to retrieve previous studies of these polymorphisms in breast cancer. Results None of the polymorphisms studied showed any overall predisposition to breast cancer susceptibility, severity or to time to death or occurrence of distant metastases. The results of the systematic review are summarised. Conclusion Polymorphisms within key interleukin genes (IL1A, IL1B, IL1RN, IL4R, IL6 and IL10 do not appear to play a significant overall role in breast cancer susceptibility or severity.

    Directory of Open Access Journals (Sweden)

    Wasiksiri, S.

    2002-07-01

    Full Text Available Breast Cancer Susceptibility Gene1 (BRCA1 is a tumor suppressor gene for breast and ovarian cancers. The gene locates at chromosome 17q21 and encodes for 1863 amino acids protein. It is believed that BRCA1 protein is involved in many functions such as DNA repair, centrosome replication, cell cycle checkpoint and replication of other genes. More than 800 mutations have been found in the population with an increased risk of cancer incidence in their families. Germ-line mutation of BRCA1 accounts for 5-10 percent of all breast cancer cases. Epigenetic modifications also reduce the function of normal BRCA1 gene. Several methods are used for laboratory diagnosis of cancer-related mutations. The development of breast cancer in carriers at risk with BRCA1 mutations may be prevented by suitable prevention plans such as breast cancer screening, ovarian cancer screening, surgery and cancer chemotherapy.

    Full Text Available Vitamin D is postulated to decrease the risk of breast cancer by inhibiting cell proliferation via the vitamin D receptor (VDR. Two common single nucleotide polymorphisms (SNPs in the VDR gene, rs1544410 (BsmI and rs2228570 (FokI, are inconsistently associated with breast cancer risk in Caucasian populations, while data for Asians are scarce. Here, we investigated the possible contribution of these SNPs to breast cancer risk in Pakistani breast cancer patients and in controls participating in a hospital-based breast cancer case-control study (PAK-BCCC.Genotyping of the BsmI and FokI SNPs was performed by PCR-based restriction fragment length polymorphism (RFLP analysis of 463 genetically enriched female breast cancer cases with known BRCA1/2 status and in 1,012 controls from Pakistan. The association between SNP genotypes and breast cancer risk was investigated by logistic regression adjusted for potential breast cancer risk factors and stratified by BRCA1/2 status and family history. Odds ratios (ORs and 95% confidence intervals (CIs were reported.The b allele of the BsmI was associated with an increased breast cancer risk (per b allele OR 1.28, 95% CI 1.09-1.49, P = 0.003. Subgroup analysis revealed that this effect was restricted to BRCA1/2 non-carriers (per b allele OR 1.33, 95% CI 1.11-1.59, P = 0.002 and was stronger in those who reported a positive family history of breast and/or ovarian cancer (per b allele OR 1.64, 95% CI 1.20-2.22, P = 0.002. No association with breast cancer risk was detected for the FokI SNP.The BsmI polymorphism in the VDR gene may be associated with an increased breast cancer risk in Pakistani women negative for BRCA1/2 germline mutations.

    2008-11-01

    Full Text Available Abstract Background Leptin, a 16 kDa polypeptide hormone, implicated in various physiological processes, exerts its action through the leptin receptor, a member of the class I cytokine receptor family. Both leptin and leptin receptor have recently been implicated in processes leading to breast cancer initiation and progression in animal models and humans. An A to G transition mutation in codon 223 in exon 6 of the leptin receptor gene, resulting in glutamine to arginine substitution (Gln223Arg, lies within the first of two putative leptin-binding regions and may be associated with impaired signaling capacity of the leptin receptor. This study was designed to assess the role of this polymorphism in breast cancer susceptibility in Nigerian women. Methods We utilized a polymerase chain reaction (PCR-based restriction fragment length polymorphism (RFLP assay to evaluate the association between the Gln223Arg polymorphism of the leptin receptor gene and breast risk in Nigeria in a case control study involving 209 women with breast cancer and 209 controls without the disease. Study participants were recruited from surgical outpatient clinics and surgical wards of four University Teaching Hospitals located in Midwestern and southeastern Nigeria between September 2002 and April 2004. Results Premenopausal women carrying at least one LEPR 223Arg allele were at a modestly increased risk of breast cancer after adjusting for confounders (OR = 1.8, 95% confidence interval [CI] 1.0–3.2, p = 0.07. There was no association with postmenopausal breast cancer risk (OR = 0.9, 95% CI 0.4–1.8, p = 0.68. Conclusion Our results suggest that the LEPR Gln223Arg polymorphism in the extracellular domain of the LEPR receptor gene is associated with a modestly increased risk of premenopausal breast cancer in Nigerian women.

Premenopausal women carrying at least one LEPR 223Arg allele were at a modestly increased risk of breast cancer after adjusting for confounders (OR = 1.8, 95% confidence interval [CI] 1.0–3.2, p = 0.07). There was no association with postmenopausal breast cancer risk (OR = 0.9, 95% CI 0.4–1.8, p = 0.68). Our results suggest that the LEPR Gln223Arg polymorphism in the extracellular domain of the LEPR receptor gene is associated with a modestly increased risk of premenopausal breast cancer in Nigerian women

    Axillary lymph node metastasis without breast involvement from ovarian cancer is rare. We report a case of a 68-year-old woman proven as ovarian serous papillary carcinoma and metastatic papillary carcinoma of the omentum on surgical diagnostic laparoscopy. In addition, a hypermetabolic lymph node was detected in left axilla and was considered a reactive benign lesion. Mammography and ultrasonography showed no focal lesion in both breasts, but ultrasonography-guided core needle biopsy for the lymph node revealed metastatic serous papillary carcinoma from ovarian origin. Even with a low incidence of axillary lymph node metastasis without breast involvement from ovarian cancer and only marginally elevated standardized uptake value in positron emission tomography, the possibility of metastasis at axillary lymph node in patients with known primary ovarian cancer must be considered.

    Data from a population-based case-control study conducted in Adelaide, South Australia, and involving 451 case-control pairs, were analysed to determine whether the associations of menstrual, reproductive, dietary and other factors with risk of breast cancer differed by oestrogen receptor (ER) status. Data on ER status were available for 380 cases. The proportion of tumours which were ER+ increased with age, and there was a higher proportion of ER+ tumours in post-menopausal than in premenopa...

  16. Traumatic neuroma in a patient with breast cancer after mastectomy: a case report and review of the literature

    2012-02-01

    Full Text Available Abstract The incidence of traumatic neuroma is extremely low, especially in those patients with breast cancer after mastectomy. There are only 10 cases reported in the literature. We report a patient who developed a palpable nodular mass near the mastectomy scar. The result of excisional biopsy was traumatic neuroma. Review of the literature reveal 10 cases with breast cancer of traumatic neuromas after mastectomy. Traumatic neuroma is a benign lesion and a reparative response of the nerve to injury, either direct/indirect trauma or chronic inflammation. Benign lesions as traumatic neuromas are more rarely seen after mastectomy. However, in order to manage patients' treatment, the most critical problem is to distinguish it from recurrent breast carcinoma. Although assistant examination methods such as ultrasound and computed tomography are valuable to a certain extent, the final diagnosis can only be confirmed on pathologic examination.

    Lesser degrees of terminal duct-lobular unit (TDLU) involution predict higher breast cancer risk; however, standardized measures to quantitate levels of TDLU involution have only recently been developed. We assessed whether three standardized measures of TDLU involution, with high intra/inter pathologist reproducibility in normal breast tissue, predict subsequent breast cancer risk among women in the Mayo benign breast disease (BBD) cohort. We performed a masked evaluation of biopsies from 99 women with BBD who subsequently developed breast cancer (cases) after a median of 16.9 years and 145 age-matched controls. We assessed three metrics inversely related to TDLU involution: TDLU count/mm(2), median TDLU span (microns, which approximates acini content), and median category of acini counts/TDLU (0-10; 11-20; 21-30; 31-50; >50). Associations with subsequent breast cancer risk for quartiles (or categories of acini counts) of each of these measures were assessed with multivariable conditional logistic regression to estimate odds ratios (ORs) and 95 % confidence intervals (CI). In multivariable models, women in the highest quartile compared to the lowest quartiles of TDLU counts and TDLU span measures were significantly associated with subsequent breast cancer diagnoses; TDLU counts quartile4 versus quartile1, OR = 2.44, 95 %CI 0.96-6.19, p-trend = 0.02; and TDLU spans, quartile4 versus quartile1, OR = 2.83, 95 %CI = 1.13-7.06, p-trend = 0.03. Significant associations with categorical measures of acini counts/TDLU were also observed: compared to women with median category of 25 acini counts/TDLU were at significantly higher risk, OR = 3.40, 95 %CI 1.03-11.17, p-trend = 0.032. Women with TDLU spans and TDLU count measures above the median were at further increased risk, OR = 3.75 (95 %CI 1.40-10.00, p-trend = 0.008), compared with women below the median for both of these metrics. Similar results were observed for combinatorial metrics of TDLU

    In a consortium including 23 637 breast cancer patients and 25 579 controls of East Asian ancestry, we investigated 70 single-nucleotide polymorphisms (SNPs) in 67 independent breast cancer susceptibility loci recently identified by genome-wide association studies (GWASs) conducted primarily in European-ancestry populations. SNPs in 31 loci showed an association with breast cancer risk at P < 0.05 in a direction consistent with that reported previously. Twenty-one of them remained statistically significant after adjusting for multiple comparisons with the Bonferroni-corrected significance level of <0.0015. Eight of the 70 SNPs showed a significantly different association with breast cancer risk by estrogen receptor (ER) status at P < 0.05. With the exception of rs2046210 at 6q25.1, the seven other SNPs showed a stronger association with ER-positive than ER-negative cancer. This study replicated all five genetic risk variants initially identified in Asians and provided evidence for associations of breast cancer risk in the East Asian population with nearly half of the genetic risk variants initially reported in GWASs conducted in European descendants. Taken together, these common genetic risk variants explain ∼10% of excess familial risk of breast cancer in Asian populations. PMID:23535825

    The paper presents a Case-Based Reasoning Tool for Breast Cancer Knowledge Management to improve breast cancer screening. To develop this tool, we combine both concepts and techniques of Case-Based Reasoning (CBR) and Data Mining (DM). Physicians and radiologists ground their diagnosis on their expertise (past experience) based on clinical cases. Case-Based Reasoning is the process of solving new problems based on the solutions of similar past problems and structured as cases. CBR is suitable for medical use. On the other hand, existing traditional hospital information systems (HIS), Radiological Information Systems (RIS) and Picture Archiving Information Systems (PACS) don't allow managing efficiently medical information because of its complexity and heterogeneity. Data Mining is the process of mining information from a data set and transform it into an understandable structure for further use. Combining CBR to Data Mining techniques will facilitate diagnosis and decision-making of medical experts.

    Traumatic neuromas are rare benign lesions that develop from non-neoplastic proliferation of axons, schwann cells, and fibroblasts at the proximal end of transected or injured nerves as a result of trauma or surgery. We present the case of a traumatic neuroma in a 47-year-old female who was treated with a right modified radical mastectomy for breast cancer 14 years ago. Ultrasound examination revealed an oval-shaped hypoechoic nodule at the 9-O'clock position in the right chest wall. Color Doppler imaging showed no increased blood flow and a positron emission tomography-computed tomography examination revealed no fluorodeoxyglucose uptake in this nodule. The typical histologic findings were present.

    Background:Breast cancer is one of the most common malignancies in women. Genome-wide association studies have identified FGFR2 as a breast cancer susceptibility gene. Common variation in other fibroblast growth factor (FGF) receptors might also modify risk. We tested this hypothesis by studying...... genotyped single-nucleotide polymorphisms (SNPs) and imputed SNPs in FGFR1, FGFR3, FGFR4 and FGFRL1 in the Breast Cancer Association Consortium.Methods:Data were combined from 49 studies, including 53 835 cases and 50 156 controls, of which 89 050 (46 450 cases and 42 600 controls) were of European ancestry......, 12 893 (6269 cases and 6624 controls) of Asian and 2048 (1116 cases and 932 controls) of African ancestry.

    BACKGROUND: In parous women preeclampsia has been associated with reduced risk of developing breast cancer. Characteristics of births following preeclamptic pregnancies may help understand mechanisms involved in the breast cancer risk reduction inferred by preeclampsia. METHODS: We conducted...... a register-based cohort study of all Danish women giving birth during 1978-2010 (n = 778,701). The association between preeclampsia and breast cancer was evaluated overall and according to birth characteristics by means of incidence rate ratios (IRR) estimated in Poisson regression models. RESULTS: Compared...... with women with non-preeclamptic pregnancies only, women with one or more preeclamptic pregnancies were 19% significantly less likely to develop breast cancer (IRR = 0.81 [95% CI 0.72-0.93]). We found some indication of greater risk reduction in women with term births, one or more previous births...

    Full Text Available Although cancer promotes inflammation, the role of inflammation in tumor-genesis is less well established. The aim was to examine if low-grade inflammation is related to post-menopausal breast cancer risk, and if obesity modifies this association.In the Malmö Diet and Cancer cohort, a nested case-control study was defined among 8,513 women free of cancer and aged 55-73 years at baseline (1991-96; 459 were diagnosed with invasive breast cancer during follow-up (until December 31st, 2010. In laboratory analyses of blood from 446 cases, and 885 controls (matched on age and date of blood sampling we examined systemic inflammation markers: oxidized (ox-LDL, interleukin (IL-1β, IL-6, IL-8, tumor necrosis factor (TNF-α, white blood cells, lymphocytes and neutrophils. Odds ratios (OR and 95% confidence intervals (CI for breast cancer risk was calculated using multivariable conditional logistic regression.Inverse associations with breast cancer were seen in fully-adjusted models, for 2nd and 3rd tertiles of ox-LDL, OR (95% CI: 0.65 (0.47-0.90, 0.63 (0.45-0.89 respectively, p-trend = 0.01; and for the 3rd tertile of TNF-α, 0.65 (0.43-0.99, p-trend = 0.04. In contrast, those in the highest IL-1β category had higher risk, 1.71 (1.05-2.79, p-trend = 0.01. Obesity did not modify associations between inflammation biomarkers and breast cancer.Our study does not suggest that low-grade inflammation increase the risk of post-menopausal breast cancer.

The associations of pathological characteristics with cumulative survival were evaluated using Kaplan–Meier analysis.Results: Univariate analyses revealed that overall survival was associated with cofilin levels, N category, TNM stage, estrogen receptor status, progesterone receptor status, and molecular subtypes. Cofilin status and TNM stage independently affected overall survival, although P-cofilin expression was not associated with patient survival. In the P-cofilin-negative subgroup, cofilin expression was significantly associated with patient survival, although cofilin expression was not significantly associated with patient survival in the P-cofilin-positive subgroup. We further analyzed the P-cofilin-negative cases and found that Ki-67 expression was significantly elevated in the subgroup that was strongly positive for

    Immunosuppression plays a pivotal role in assisting tumors to evade immune destruction and promoting tumor development. We hypothesized that genetic variation in the immunosuppression pathway genes may be implicated in breast cancer tumorigenesis. We included 42,510 female breast cancer cases and 40,577 controls of European ancestry from 37 studies in the Breast Cancer Association Consortium (2015) with available genotype data for 3595 single nucleotide polymorphisms (SNPs) in 133 candidate genes. Associations between genotyped SNPs and overall breast cancer risk, and secondarily according to estrogen receptor (ER) status, were assessed using multiple logistic regression models. Gene-level associations were assessed based on principal component analysis. Gene expression analyses were conducted using RNA sequencing level 3 data from The Cancer Genome Atlas for 989 breast tumor samples and 113 matched normal tissue samples. SNP rs1905339 (A>G) in the STAT3 region was associated with an increased breast cancer risk (per allele odds ratio 1.05, 95 % confidence interval 1.03-1.08; p value = 1.4 × 10(-6)). The association did not differ significantly by ER status. On the gene level, in addition to TGFBR2 and CCND1, IL5 and GM-CSF showed the strongest associations with overall breast cancer risk (p value = 1.0 × 10(-3) and 7.0 × 10(-3), respectively). Furthermore, STAT3 and IL5 but not GM-CSF were differentially expressed between breast tumor tissue and normal tissue (p value = 2.5 × 10(-3), 4.5 × 10(-4) and 0.63, respectively). Our data provide evidence that the immunosuppression pathway genes STAT3, IL5, and GM-CSF may be novel susceptibility loci for breast cancer in women of European ancestry. PMID:26621531

    One in every 12 women will develop breast cancer; the incidence increases with age, dietary fat intake, caloric intake, height, and weight. The 10-year survival rate of breast cancer patients who refuse therapy is virtually zero. Segmental mastectomy plus radiation and lumpectomy, combined with systemic (adjuvant)chemotherapy, are alternatives under investigation at the National Institutes of Health that may increase the survival rate by decreasing metastatic complications.

    Objective: This study was performed to exam the relativeship between mammographic calcifications and breast cancer. Methods: All of the 184 patients with breast diseases underwent mammography before either an open biopsy or a mastectomy. The presence,morphology, and distribution of calcifications visualized on mammograms for breast cancer were compared with the controls who remained cancer free. Statistical comparisons were made by using the x2 test. Results:Of the 184 patients with breast diaeases, 93 malignant and 91 benign lesions were histologically confirmed.Calcifications were visualized on mammograms in 60(64%) of 93 breast cancers and 26 (28%) of 91 non breast cancers. The estimated odds ratio (OR) of breast cancer was 4.5 in women with calcifications seen on mammograms, compared with those having none (P<0.01). Of the 60 breast carcinomas having mammographic calcifications, 28 (47%) were infiltrating ductal carcinomas.There were only 8 (24%) cases with infiltrating ductal cancers in the group of without calcifications seen on the mammograms (P<0.05). Conclusion: Our finding suggests that mammographic calcification appears to be a risk factor for breast cancer. The granular and linear cast type calcification provide clues to the presence of breast cancer, especially when the carcinomas without associated masses were seen on mammograms.

    A dietary case-control study based on 818 newly diagnosed breast cancer (BC) patients was conducted in Israel between 1975 and 1978. The role of coffee and total methylxanthine intake from coffee, tea, cola, chocolate, and cocoa drinks was evaluated in the BC patients as compared to that in two matched control populations [surgical controls (SC) and neighborhood controls (NC)]. Because it has been suggested that caffeine enhances mammary carcinogenesis in rats fed high polyunsaturated fat diets, analysis was done also in relation to fat consumption. When comparison was done to both matched control groups, a nonsignificant negative association was found between consumption of cups of coffee and BC (odds ratios of greater than or equal to 4 cups of coffee/day vs. less than or equal to 1 per week = 0.6 for BC/NC and 0.7 for BC/SC). This association was observed in all 3 ethnic subgroups studied. The pattern was stronger among the high-fat consumers after controlling for several hormonal confounding factors (two-tailed P-value for linear trend = 0.06 for SC and P = 0.05 for NC). In addition, when the consumption of methylxanthine of BC patients was compared to that of benign breast patients, adjusted by age and ethnic group, a diminished risk was found (odds ratio for BC of the highest level of methylxanthine vs. lowest level = 0.59).

    Breast cancer is one of the most common female malignant tumors. According to data statistics, the incidence of breast cancer was 7% to 10% for a variety of malignant tumors, being only lower than that of uterine cancer. The methods of treating breast cancer are given priority over operative treatment and combined with chemotherapy and radiotherapy. However, exosmosis of chemotherapeutic drugs is a common complication of chemotherapy. Exosmosis of drugs can stimulate local organs to induce acute inflammatory reaction and necrosis, which finally lead to wound infection and difficulty in healing. In December 2013, a patient with full-thickness wound (an area of 5 × 3 cm) dehiscence at the completion of the second phase of chemotherapy for left breast cancer after radical operation was admitted to our department. Her wound had healed after radical operation. The patient followed an integrative therapy treatment protocol that consisted of an external application of a phytomedicine called Sanguis Draconis and combined with a series of conventional treatments, including 3M Transparent Dressing moist therapy, increase in nutrition, and prevention therapies for infection. The patient's integrative treatment program resulted in complete wound healing, and the successful completion of the late 6 courses of chemotherapy. The article describes the nursing experiences associated with this case study.

    Full Text Available Abstract Background Accumulative evidence suggests that low folate intake is associated with increased risk of breast cancer. Polymorphisms in genes involved in folate metabolism may influence DNA methylation, nucleotide synthesis, and thus individual susceptibility to cancer. Thymidylate synthase (TYMS is a key enzyme that participates in folate metabolism and catalyzes the conversion of dUMP to dTMP in the process of DNA synthesis. Two potentially functional polymorphisms [a 28-bp tandem repeat in the TYMS 5'-untranslated enhanced region (TSER and a 6-bp deletion/insertion in the TYMS 3'-untranslated region (TS 3'-UTR] were suggested to be correlated with alteration of thymidylate synthase expression and associated with cancer risk. Methods To test the hypothesis that polymorphisms of the TYMS gene are associated with risk of breast cancer, we genotyped these two polymorphisms in a case-control study of 432 incident cases with invasive breast cancer and 473 cancer-free controls in a Chinese population. Results We found that the distribution of TS3'-UTR (1494del6 genotype frequencies were significantly different between the cases and controls (P = 0.026. Compared with the TS3'-UTR del6/del6 wild-type genotype, a significantly reduced risk was associated with the ins6/ins6 homozygous variant genotype (adjusted OR = 0.58, 95% CI = 0.35–0.97 but not the del6/ins6 genotype (OR = 1.09, 95% CI = 0.82–1.46. Furthermore, breast cancer risks associated with the TS3'-UTR del6/del6 genotype were more evident in older women, postmenopausal subjects, individuals with a younger age at first-live birth and individuals with an older age at menarche. However, there was no evidence for an association between the TSER polymorphism and breast cancer risks. Conclusion These findings suggest that the TS3'-UTR del6 polymorphism may play a role in the etiology of breast cancer. Further larger population-based studies as well as functional evaluation of the

  18. Genetic variation in TLR or NFkappaB pathways and the risk of breast cancer: a case-control study

    International Nuclear Information System (INIS)

    Toll-like receptors (TLRs) and the transcription factor nuclear factor-κB (NFκB) are important in inflammation and cancer. We examined the association between breast cancer risk and 233 tagging single nucleotide polymorphisms within 31 candidate genes involved in TLR or NFκB pathways. This population-based study in the Seattle area included 845 invasive breast cancer cases, diagnosed between 1997 and 1999, and 807 controls aged 65–79. Variant alleles in four genes were associated with breast cancer risk based on gene-level tests: MAP3K1, MMP9, TANK, and TLR9. These results were similar when the risk of breast cancer was examined within ductal and luminal subtypes. Subsequent exploratory pathway analyses using the GRASS algorithm found no associations for genes in TLR or NFκB pathways. Using publicly available CGEMS GWAS data to validate significant findings (N = 1,145 cases, N = 1,142 controls), rs889312 near MAP3K1 was confirmed to be associated with breast cancer risk (P = 0.04, OR 1.15, 95% CI 1.01–1.30). Further, two SNPs in TANK that were significant in our data, rs17705608 (P = 0.05) and rs7309 (P = 0.04), had similar risk estimates in the CGEMS data (rs17705608 OR 0.83, 95% CI 0.72–0.96; CGEMS OR 0.90, 95% CI 0.80–1.01 and rs7309 OR 0.83, 95% CI 0.73–0.95; CGEMS OR 0.91, 95% CI 0.81–1.02). Our findings suggest plausible associations between breast cancer risk and genes in TLR or NFκB pathways. Given the few suggestive associations in our data and the compelling biologic rationale for an association between genetic variation in these pathways and breast cancer risk, further studies are warranted that examine these effects

For over 50 years, there have been serious attempts to identify viruses which may have a role in breast cancer. Despite these efforts, the establishment of conclusive evidence for such a role has been elusive. However, the development of extremely sophisticated new experimental techniques has allowed the recent development of evidence that human papilloma virus, Epstein-Barr virus, mouse mammary tumor virus and bovine leukemia virus may each have a role in the causation of human breast cancers.

    The hypothesis has been raised that coffee consumption may increase the incidence of breast cancer, based on the report that fibrocystic breast disease, a risk factor for breast cancer, regresses after abstention from coffee and other methylxanthines. The relation between recent coffee consumption and the risk of breast cancer was evaluated in a case-control study, based on interviews conducted 1975-1982 at several mainly eastern US teaching and community hospitals. The responses of 2,651 women with newly diagnosed breast cancer were compared with those of 1,501 controls with nonmalignant conditions and 385 controls with cancers at other sites. The relative risk estimates for levels of coffee drinking up to seven or more cups daily, relative to none, approximated 1.0 with narrow 95% confidence intervals. After allowance for confounding, the relative risk estimate for drinking at least five cups a day was 1.2 (95% confidence interval, 0.9-1.6) using the noncancer controls and 1.1 (0.7-1.6) using the cancer controls. Coffee consumption was not associated with an increase in the risk of breast cancer among women with a history of fibrocystic breast disease, nor were tea or decaffeinated coffee associated with an increase in the risk of breast cancer. The results suggest that the recent consumption of coffee does not influence the incidence of breast cancer. PMID:4025289

  6. Gene × Gene interaction between MnSOD and GPX-1 and breast cancer risk: a nested case-control study

    International Nuclear Information System (INIS)

    Germ-line mutations in genes such as BRCA1, BRCA2, and ATM can cause a substantial increase in risk of breast cancer. However, these mutations are rare in the general population, and account for little of the incidence of sporadic breast cancer in the general population. Therefore, research has been focused on examining associations between common polymorphisms and breast cancer risk. To date, few associations have been described. This has led to the hypothesis that breast cancer is a complex disease, whereby a constellation of very low penetrance alleles need to be carried to present a risk phenotype. Polymorphisms in the manganese superoxide dismutase (MnSOD) and glutathione peroxidase (GPX-1) genes have been proposed as low penetrance alleles, and have not been clearly associated with breast cancer. We investigated whether variants at both polymorphisms, while not independently associated with breast cancer risk, could influence breast cancer risk when considered together. A case-control study nested within the Nurses' Health Study was performed comparing 1262 women diagnosed with breast cancer to 1533 disease free women. The MnSOD (Val16Ala, rs1799725) and GPX-1 (Pro198Leu, rs1050450) were genotyped via TaqMan assay. Disease risk was evaluated using logistic regression. While neither allele alone shows any change in breast cancer risk, an increase in the risk of breast cancer (OR 1.87, 95% CI 1.09 – 3.19) is observed in individuals who carry both the Ala16Ala genotype of MnSOD and the Leu198Leu genotype of GPX-1. Polymorphisms in the GPX-1 and MnSOD genes are associated with an increased risk of breast cancer

    The BioScan System was developed by OmniCorder Technologies, Inc. at the Jet Propulsion Laboratory. The system is able to locate cancerous lesions by detecting the cancer's ability to recruit a new blood supply. A digital sensor detects infrared energy emitted from the body and identifies the minute differences accompanying the blood flow changes associated with cancerous cells. It also has potential use as a monitoring device during cancer treatment. This technology will reduce the time taken to detect cancerous cells and allow for earlier intervention, therefore increasing the overall survival rates of breast cancer patients.

    Regarding 'mate' intake (infusion of Ilex paraguariensis herb, a staple beverage in temperate South American regions), most epidemiologic studies showed positive associations with risk of some cancers, (e.g. upper aerodigestive tract), but evidence on breast cancer (BC) risk is limited to a previous multi-site study, which reported a non significant odds ratio [OR]=0.85, 95% confidence interval [95% CI] 0.67-1.09, p for trend=0.31) for the highest quartile of intake. The present study was conducted in order to further assess associations of 'mate' intake with BC risk. We combined two databases of women belonging to public and private healthcare hospitals. The sample included 572 BC incident cases and 889 controls interviewed with a specific questionnaire featured by socio-demographic, reproductive and lifestyle variables, and a food frequency questionnaire of 64 items, also analyzing 'mate' intake (consumer status, daily intake, age at start, age at quit, duration of habit, intensity of intake). ORs and their 95%CI were calculated through unconditional logistic regression, adjusting for relevant potential confounders. The highest quartile of 'mate' intake was inversely associated with BC risk (OR=0.40, 95%CI 0.26-0.57, p for trend women (OR=0.36), among other results. As conclusions, we found evidence of a significant inverse association for 'mate' intake and BC risk. PMID:27039789

    Full Text Available Demodex folliculorum and Demodex brevis are obligatory parasites that live in sebaceous glands and follicles. When immune system becomes suppressed by any reason, patients become vulnerable to obligatory parasites like D. folliculorum and D. brevis. Immune system becomes suppressed in cancer patients who undergo chemotherapy, and as a result these patients become vulnerable to infestations. In our case, a 45 year-old female has been admitted to oncology clinic for a medical treatment of breast cancer. Her systematic physical examination was normal, except redness on her cheeks and forehead. There was no abnormality in biochemical and haematological laboratory values. We have decided to apply chemotherapy of Adriamycin, cyclophosphamide and 5-fluorouracil. Due to the itchy redness on her cheeks and forehead, we had performed an examination for demodex before chemotherapy; and we have identified 20 mites/cm2 on her right and left cheeks, and 15 mites/cm2 on her forehead. When our patient had came our clinic with increasing complaint of itchy rash, after the first course of chemotherapy we have reexamined demodex. The result of microscopic examination revealed large amount of demodex of 50 mites/cm2 on her right and left cheeks and 30 mites/cm2 on her forehead, which were nearly 2.5-times higher than the previous examination. This increase probably was associated with immune suppression of chemotherapy.

    Background Results from epidemiologic studies on the relationship between vitamin D and breast cancer risk are inconclusive. It is possible that vitamin D may be effective in reducing risk only of specific subtypes due to disease heterogeneity. Methods and Findings In case-control and case-series analyses, we examined serum concentrations of 25-hydroxyvitamin D (25OHD) in relation to breast cancer prognostic characteristics, including histologic grade, estrogen receptor (ER), and molecular subtypes defined by ER, progesterone receptor (PR) and HER2, among 579 women with incident breast cancer and 574 controls matched on age and time of blood draw enrolled in the Roswell Park Cancer Institute from 2003 to 2008. We found that breast cancer cases had significantly lower 25OHD concentrations than controls (adjusted mean, 22.8 versus 26.2 ng/mL, p<0.001). Among premenopausal women, 25OHD concentrations were lower in those with high- versus low-grade tumors, and ER negative versus ER positive tumors (p≤0.03). Levels were lowest among women with triple-negative cancer (17.5 ng/mL), significantly different from those with luminal A cancer (24.5 ng/mL, p = 0.002). In case-control analyses, premenopausal women with 25OHD concentrations above the median had significantly lower odds of having triple-negative cancer (OR = 0.21, 95% CI = 0.08–0.53) than those with levels below the median; and every 10 ng/mL increase in serum 25OHD concentrations was associated with a 64% lower odds of having triple-negative cancer (OR = 0.36, 95% CI = 0.22–0.56). The differential associations by tumor subtypes among premenopausal women were confirmed in case-series analyses. Conclusion In our analyses, higher serum levels of 25OHD were associated with reduced risk of breast cancer, with associations strongest for high grade, ER negative or triple negative cancers in premenopausal women. With further confirmation in large prospective studies, these findings could warrant

    We employed a semi-Markov multistate model for the simultaneous analysis of various endpoints describing the course of breast cancer. Results were compared with those from standard analyses using a Cox proportional hazards model. We included 3,012 patients with invasive breast cancer newly diagnosed between 2001 and 2005 who were recruited in Germany for a population-based study, the Mamma Carcinoma Risk Factor Investigation (MARIE Study), and prospectively followed up until the end of 2009. Locoregional recurrence and distant metastasis were included as intermediate states, and deaths from breast cancer, secondary cancer, and other causes were included as competing absorbing states. Tumor characteristics were significantly associated with all breast cancer-related endpoints. Nodal involvement was significantly related to local recurrence but more strongly related to distant metastases. Smoking was significantly associated with mortality from second cancers and other causes, whereas menopausal hormone use was significantly associated with reduced distant metastasis and death from causes other than cancer. The presence of cardiovascular disease at diagnosis was solely associated with mortality from other causes. Compared with separate Cox models, multistate models allow for dissection of prognostic factors and intermediate events in the analysis of cause-specific mortality and can yield new insights into disease progression and associated pathways.

  2. Genetic analysis of the vitamin D receptor gene in two epithelial cancers: melanoma and breast cancer case-control studies

    International Nuclear Information System (INIS)

    Vitamin D serum levels have been found to be related to sun exposure and diet, together with cell differentiation, growth control and consequently, cancer risk. Vitamin D receptor (VDR) genotypes may influence cancer risk; however, no epidemiological studies in sporadic breast cancer (BC) or malignant melanoma (MM) have been performed in a southern European population. In this study, the VDR gene has been evaluated in two epithelial cancers BC and MM. We have conducted an analysis in 549 consecutive and non-related sporadic BC cases and 556 controls, all from the Spanish population, and 283 MM cases and 245 controls. Genotyping analyses were carried out on four putatively functional SNPs within the VDR gene. An association with the minor allele A of the non-synonymous SNP rs2228570 (rs10735810, FokI, Met1Thr) was observed for BC, with an estimated odds ratio (OR) of 1.26 (95% CI = 1.02–1.57; p = 0.036). The synonymous variant rs731236 (TaqI) appeared to be associated with protection from BC (OR = 0.80, 95%CI = 0.64–0.99; p = 0.047). No statistically significant associations with MM were observed for any SNP. Nevertheless, sub-group analyses revealed an association between rs2228570 (FokI) and absence of childhood sunburns (OR = 0.65, p = 0.003), between the 3'utr SNP rs739837 (BglI) and fair skin (OR = 1.31, p = 0.048), and between the promoter SNP rs4516035 and the more aggressive tumour location in head-neck and trunk (OR = 1.54, p = 0.020). In summary, we observed associations between SNPs in the VDR gene and BC risk, and a comprehensive analysis using clinical and tumour characteristics as outcome variables has revealed potential associations with MM. These associations required confirmation in independent studies

    INTRODUCTION: Digoxin use is associated with increased incidence of breast and uterus cancers. We postulated that digoxin use might affect tumor characteristics and increase relapse risk in women with breast cancer. METHODS: Incident breast cancer cases in Danish women (n = 49,312; 1995 to 2008...... in Cox regression models. RESULTS: At diagnosis, tumors in digoxin users were more likely ER+ (85.4% vs. 78.6%: P = 0.002) and have grade 1 ductal histology (37.2% vs. 25.7%; P = 0.004), compared to non-users. 45 relapses occurred in women already using digoxin at breast cancer diagnosis (1,487 person...... cancers arising in digoxin-using women had better prognostic features. After adjustment for markers, overall breast cancer relapse risk in digoxin users was not increased significantly, although recurrence hazards for ER+ tumors were higher in the first year following diagnosis....

    BACKGROUND: Manganese superoxide dismutase (MnSOD) inhibits oxidative damage and cancer therapy effectiveness. A polymorphism in its encoding gene (SOD2: Val16Ala rs4880) may confer poorer breast cancer survival, but data are inconsistent. We examined the association of SOD2 genotype and breast......-metastatic breast cancer from 1990-2001, received adjuvant Cyclo, and were registered in the Danish Breast Cancer Cooperative Group. We identified 118 patients with BCR and 213 matched breast cancer controls. We genotyped SOD2 and used conditional logistic regression to compute the odds ratio (OR) and associated 95...... cancer recurrence (BCR) among patients treated with cyclophosphamide-based chemotherapy (Cyclo). We compared our findings with published studies using meta-analyses. METHODS: We conducted a population-based case-control study of BCR among women in Jutland, Denmark.

    The prognosis associated with brain metastasis arising from breast cancer is very poor. Eribulin is a microtubule dynamic inhibitor synthesized from halichondrin B, a natural marine product. In a phase III study (EMBRACE), eribulin improved overall survival in patients with heavily pretreated metastatic breast cancers. However, these studies included few patients with brain metastases. Metastatic brain tumors (MBT) were detected during first-line palliative chemotherapy in a 43-year-old woman with breast cancer metastasis to the lung and mediastinal nodes; the genetic subtype was luminal B-like human epidermal growth factor receptor 2 (HER2)-negative. Whole brain radiotherapy (WBRT) followed by eribulin treatment continuously decreased the size, and induced regression, of the MBT with systemic disease stability for 12 months. Another 48-year-old woman with metastatic breast cancer (HER2+ subtype) presented with MBT. Following surgical resection of the tumor, eribulin with concurrent WBRT showed regression of the MBT without systemic progression for 18 months. PMID:27382400

    Introduction Percent mammographic density (PMD) is a strong and highly heritable risk factor for breast cancer. Studies of the role of PMD in familial breast cancer may require controls, such as the sisters of cases, selected from the same 'risk set' as the cases. The use of sister controls would allow control for factors that have been shown to influence risk of breast cancer such as race/ethnicity, socioeconomic status and a family history of breast cancer, but may introduce 'overmatching' ...

    Full Text Available Background: The traditional methods of studying the gene-environment interactions need a control group. However, the selection of an appropriate control group has been associated with problems. Therefore, new methods, such as case-only design, have been created to study such interactions. The objective of this study was to compare the case-only and case-control designs using data from patients with breast cancer.Methods: The interaction of genetic and environmental factor as well as the ratio of control to population odds ratio was calculated for case-only (300 patients with breast cancer and case-control (300 cases of breast cancer and 300 matched controls designs. Results: The confidence intervals and -2log likelihood in all variables in case-only design was smaller than those in the matched case-control design. In case-only design, the standard errors of some variables such as age at menarche, the first delivery at the age of 35 yrs and more or no delivery, the history of having live birth, use of oral contraception pills, breastfeeding history were less than those in the matched case-control design. Conclusion: The findings indicate that the case-only design is an efficient method to investigate the interaction of genetic and environmental factors.

    2013-01-01

    Background: Data regarding the safety and effectiveness of aromatase inhibitors (AIs) as monotherapy or combined with gonadotropin-releasing hormone (GnRH) analogue in male breast cancer are scarce. Methods: In this retrospective chart review, cases of male breast cancer patients treated with AIs with or without a GnRH analogue were evaluated. Results: Twenty-three men were included into this case series. Aromatase inhibitors in combination with or without a GnRH analogue were given as first-line therapy in 60.9% and as second-line therapy in 39.1% of patients, respectively. All patients had visceral metastases, whereas in five of them bone lesions coexisted. In all cases AIs were tolerated well, and no case of grade 3 and 4 adverse events was reported. A partial response was observed in 26.1% of patients and stable disease in 56.5%. Median overall survival (OS) was 39 months and median progression-free survival (PFS) was 13 months. Regarding OS and PFS, no significant effects of GnRH analogue co-administration or type of AI were noted. Conclusion: Our study shows that AIs with or without GnRH analogues may represent an effective and safe treatment option for hormone-receptor positive, pretreated, metastatic, male breast cancer patients.

    This retrospective analysis was performed to evaluate osteolytic bone lesions of breast cancer in the thoracic and lumbar spine after radiotherapy (RT) in terms of stability using a validated scoring system. The stability of 157 osteolytic metastases, treated from January 2000 to January 2012, in 115 patients with breast cancer was evaluated retrospectively using the Taneichi score. Predictive factors for stability were analyzed and survival rates were calculated. Eighty-five (54 %) lesions were classified as unstable prior to RT. After 3 and 6 months, 109 (70 %) and 124 (79 %) lesions, respectively, were classified as stable. Thirty fractures were detected prior to RT, and after RT seven cases (4.5 %) with pathologic fractures were found within 6 months. None of the examined predictive factors showed significant correlation with stability 6 months after RT. After a median follow-up of 16.7 months, Kaplan-Meier estimates revealed an overall survival of 83 % after 5 years. The majority of patients showed an improved or unchanged stability of the involved vertebral bodies after 6 months. The patients showed only minor cancer-related morbidity during follow-up and reached comparably high survival rates. (orig.)

    Full Text Available In order to analyze detailed anthropometric characterisation for risk of breast cancer (BC in premenopausal Uruguayan women, a case-control study was carried out at the Pereira Rossell Women’s Hospital, Montevideo, where 253 incident BC cases and 497 frequency-matched healthy controls were interviewed on menstrual and reproductive story, and a series of body measurements were performed to calculate body composition and somatotype. Odds ratio (OR’s coefficients were taken as estimates of relative risk derived from unconditional logistic regression. Results show a positive association for the fat fraction (OR for highest quartile =4.19, 95% CI (95% Confidence Interval 2.70-6.50 as well as for the fat-to-muscle ratio (OR=4.68, 95% CI 2.98-7.36. Muscle fraction was inversely associated with risk (OR=0.53 95% CI 0.36-0.78. High endomorphism was the only somatotype variable associated to the disease risk (OR=1.69, 95% CI 1.13-2.54, however, losing its association when fat amount was included in the regression model. Stratified analyses by body mass index (BMI levels, bone weight, age groups and number of live births also showed risk increases for the highest fat fractions, displaying significant linear trends. Albeit most of the literature reports a putative slight protective effect for a high BMI in premenopausal women, our results suggest that fat fraction, amount and distribution might play a role as predisposing factors for premenopausal BC.

    We evaluated individual grain-containing foods and whole and refined grain intake during adolescence, early adulthood, and premenopausal years in relation to breast cancer risk in the Nurses' Health Study II. Grain-containing food intakes were reported on a baseline dietary questionnaire (1991) and every 4 years thereafter. Among 90,516 premenopausal women aged 27-44 years, we prospectively identified 3235 invasive breast cancer cases during follow-up to 2013. 44,263 women reported their diet during high school, and from 1998 to 2013, 1347 breast cancer cases were identified among these women. Cox proportional hazards regression was used to estimate relative risks (RR) and 95 % confidence intervals (95 % CI) of breast cancer for individual, whole and refined grain foods. After adjusting for known breast cancer risk factors, adult intake of whole grain foods was associated with lower premenopausal breast cancer risk (highest vs. lowest quintile: RR 0.82; 95 % CI 0.70-0.97; P trend = 0.03), but not postmenopausal breast cancer. This association was no longer significant after further adjustment for fiber intake. The average of adolescent and early adulthood whole grain food intake was suggestively associated with lower premenopausal breast cancer risk (highest vs lowest quintile: RR 0.74; 95 % CI 0.56-0.99; P trend = 0.09). Total refined grain food intake was not associated with risk of breast cancer. Most individual grain-containing foods were not associated with breast cancer risk. The exceptions were adult brown rice which was associated with lower risk of overall and premenopausal breast cancer (for each 2 servings/week: RR 0.94; 95 % CI 0.89-0.99 and RR 0.91; 95 % CI 0.85-0.99, respectively) and adult white bread intake which was associated with increased overall breast cancer risk (for each 2 servings/week: RR 1.02; 95 % CI 1.01-1.04), as well as breast cancer before and after menopause. Further, pasta intake was inversely associated with

    Full Text Available We report a case of pregnancy-associated breast cancer with metastasis to the brain, likely resulting from hereditary breast and ovarian cancer (HBOC. A 35-year-old woman (gravida 2, para 0-1-0-1 underwent a right mastectomy and right axillary dissection after a cesarean section at 30 years of age; her mother died at 47 years of age due to breast cancer. Histopathological examination indicated an invasive ductal carcinoma with triple-negative cancer (cancer stage 2B [pT3N0M0]. The patient refused adjuvant therapy because of the risk of infertility. After 4 years, she became pregnant naturally. At 18 weeks’ gestation, she experienced aphasia and dyslexia due to brain metastasis. The pregnancy was terminated at 21 weeks’ gestation after thorough counseling. Her family history, young-onset disease, and histopathological findings suggested HBOC. She declined genetic testing for BRCA1/2, though genetic counseling was provided. In cases of pregnancy-related breast cancer, consideration must be given to whether the pregnancy should be continued and to posttreatment fertility. HBOC should also be considered. Genetic counseling should be provided and the patient should be checked for the BRCA mutation, as it is meaningful for the future of any potential children. Genetic counseling should be provided even if the cancer is advanced or recurrent.

  20. KRAS rs61764370 is associated with HER2-overexpressed and poorly-differentiated breast cancer in hormone replacement therapy users: a case control study

    International Nuclear Information System (INIS)

    A single nucleotide polymorphism located in the 3'-untranslated region of the KRAS oncogene (KRAS variant; rs61764370) disrupts a let-7 miRNA binding and was recently reported to act as a genetic marker for increased risk of developing human cancers. We aimed to investigate an association of the KRAS variant with sporadic and familial breast cancer and breast tumor characteristics. Genotyping was accomplished in 530 sporadic postmenopausal breast cancer cases, 165 familial breast cancer cases (including N = 29, who test positive for BRCA1/2 mutations) and 270 postmenopausal control women using the flurogenic 5' nuclease assay. Information on hormone replacement therapy (HRT) use and tumor characteristics in sporadic breast cancer cases was ascertained from a postal questionnaire and pathology reports, respectively. Associations between the KRAS genotype and breast cancer or breast tumor characteristics were assessed using chi-square test and logistic regression models. No evidence of association was observed between the KRAS variant and risk of sporadic and familial breast cancer - either among BRCA carriers or non-BRCA carriers. The KRAS variant was statistically significantly more often associated with human epidermal growth factor receptor 2 (HER2) - positive tumors and tumors of higher histopathologic grade. However, both associations were detected only in HRT users. Our data do not support the hypothesis that the KRAS variant rs61764370 is implicated in the aetiology of sporadic or of familial breast cancer. In postmenopausal women using HRT, the KRAS variant might lead to HER2 overexpressed and poorly-differentiated breast tumors, both indicators of a worse prognosis

American, Dutch, Swedish and Italian studies spanning the 1960s to the 1980s reveal a benefit from screening (reduced mortality from breast cancer) that occurs unambiguously only in women 50 years of age and over. Physicians who choose to screen mammographically their over-49-year-old female patients must do so with the ...

    Full Text Available Abstract Background The relationship between breast cancer and organochlorine exposure is controversial and complex. As estrogen receptor positive and negative breast cancer may represent different entities of the disease, this study was undertaken to evaluate organochlorines influence on breast cancer risk and survival according to receptor status. Methods The background material stems from the Copenhagen City Heart Study (Denmark 1976-78. The breast cancer risk was investigated in a cohort nested case-control design including 161 cases and twice as many breast cancer free controls. The cases served as a cohort in the survival analysis. Serum organochlorine concentrations were determined by gaschromotography. Results The observed increased breast cancer risk associated with exposure to dieldrin derived from women who developed an estrogen receptor negative (ERN tumor (Odds ratio [OR] I vs. IV quartile, 7.6, 95% confidence interval [95% CI] 1.4-46.1, p-value for linear trend 0.01.

In the highest quartile of polychlorinated biphenyls (ΣPCB it was more than 2-fold increased (Relative risk [RR] I vs. IV quartile, 2.5, 95% CI 1.1-5.7, but no dose-response relation was apparent. Conclusion The results do not suggest that exposure to potential estrogenic organochlorines leads to development of an ERP breast cancer. A possible adverse effect on prognosis of hormone-responsive breast cancers needs to be clarified.

    Full Text Available BACKGROUND Breast cancer is the most common malignant tumour in women worldwide. The relationship between breast cancer and thyroid disease is a controversy. Many of the studies showed hypothyroidism as the commonly found thyroid abnormality in breast cancer. [1] There is considerable evidence for an increased risk of thyroid and breast cancer in patients with iodine deficiency. This ability of iodine to reduce the risk of breast cancer is attributed to the ability of iodine and its compounds to induce apoptosis so that appropriate cell death occurs. Instead, in the absence of optimum level of iodine in the body the transformed cells continue to grow and divide resulting in cancer. AIMS 1. To find out the association of thyroid hormones and breast cancer in early breast cancer patients. 2. To find out the association of thyroid peroxidase antibodies in early breast cancer patients. Settings Cases: 82 breast cancer patients in early stage who attended the breast clinic. Controls: 82 age matched controls (Between 25-80 years. Design: Case control study. MATERIALS AND METHOD In this study, investigated for thyroid function test (T3, T4, TSH and thyroid peroxide antibody level in 82 early breast cancer patients. STATISTICAL ANALYSIS SPSS 16. RESULTS Statistically significant low T4 and high TSH in breast cancer patients, along with elevated thyroid peroxidase antibody.

    Full Text Available Jane Bryce1, Martina Bauer2, Peyman Hadji21National Cancer Institute, Naples, Italy; 2Philipps University of Marburg, Marburg, GermanyBackground: In order to reduce the risk of recurrence, adjuvant treatment with an aromatase inhibitor (AI is recommended for postmenopausal women following surgery for hormone receptor-positive breast cancer. AIs are associated with improved disease-free survival compared with tamoxifen. The adverse events associated with AIs resemble those of menopause, such as bone density loss and musculoskeletal symptoms.Purpose: We examine the case of a postmenopausal woman who was prescribed anastrozole, a nonsteroidal AI, as adjuvant therapy following surgery for estrogen and progesterone receptor-positive (ER and PgR+ breast cancer.Methods and sample: A 58-year-old postmenopausal woman diagnosed with ER and PgR+ breast cancer was prescribed anastrozole as adjuvant therapy following a right-inferior quadrantectomy. After experiencing joint pain and stiffness, she was prescribed paracetamol and a topical nonsteroidal anti-inflammatory drug. She was also counseled on nonpharmacological interventions. However, she continued to experience symptoms, and reported that she was not taking anastrozole regularly.Results: The case study patient ultimately found relief by switching to letrozole, another aromatase inhibitor. This approach is supported by recent studies examining the benefits of switching strategies between aromatase inhibitors in order to relieve symptoms of arthralgia/myalgia.Conclusions: Both adherence and strategies for managing aromatase inhibitor-associated arthralgia are key to deriving maximal clinical benefit from AI therapy. Switching from one aromatase inhibitor to another may provide a viable option in managing adverse events and enhancing adherence to medication.Keywords: adherence, anastrozole, aromatase inhibitor, arthralgia, breast cancer, letrozole

    A 47-year-old Korean woman with right middle lobe lung adenocarcinoma, malignant pleural effusion, and multiple lymph node and bone metastases, after three months of lung cancer diagnosis, presented with a palpable right breast mass. Images of the right breast demonstrated architectural distortion that strongly suggested primary breast cancer. Breast biopsy revealed metastatic lung cancer with a negative result for estrogen receptor (ER), progesterone receptor (PR) and mammaglobin, and a positive result for thyroid transcription factor-1 (TTF-1). We present a case of breast metastasis from a case of lung cancer with an extensive micropapillary component, which was initially misinterpreted as a primary breast cancer due to unusual image findings with architectural distortion.

    Full Text Available This paper presents a case of a patient with invasive ductal breast cancer following breast augmentation. Following breast implants rupture in March 2013 the breast implants have been removed – histopathological examination revealed leaked silicone with inflammatory infiltration, without evidence of cancerous lesions. Diagnostic imaging revealed multiple encapsulated silicone particles and clusters of post-inflammatory macrocalcifications in both breasts. In January 2014 the patient presented with symptoms of massive inflammation of the left breast. Following surgical consultation the patient had undergone radical left-sided mastectomy with lymphadenectomy. Postoperative histopathological examination revealed a multifocal advanced invasive ductal cancer G3 pT3pN3a (vascular invasion, metastases in 11 of 12 examined axillary lymph nodes. Following surgery the patient was qualified for further treatment – chemotherapy, radiotherapy, hormone therapy. The discussion includes a review of literature on the risk evaluation of co-occurrence of breast cancers in women with silicone breast implants and presents diagnostic challenges of breast cancer in this patient group.

    Full Text Available Functional neuroimaging is an innovative but at this stage underutilized method to assess the efficacy of psychotherapy for depression. Functional magnetic resonance imaging (fMRI was used in this case study to examine changes in brain activity in a depressed breast cancer patient receiving an 8-session Behavioral Activation Treatment for Depression (BATD, based on the work of Hopko and Lejuez (2007. A music listening paradigm was used during fMRI brain scans to assess reward responsiveness at pre- and posttreatment. Following treatment, the patient exhibited attenuated depression and changes in blood oxygenation level dependence (BOLD response in regions of the prefrontal cortex and the subgenual cingulate cortex. These preliminary findings outline a novel means to assess psychotherapy efficacy and suggest that BATD elicits functional brain changes in areas implicated in the pathophysiology of depression. Further research is necessary to explore neurobiological mechanisms of change in BATD, particularly the potential mediating effects of reward responsiveness and associated brain functioning.

    Summary. Breast cancer is by far the most common cancer in women in the western world. In 90% of breast cancers, environmental factors are among the causes. The frequency with which the tumour occurs in the outer upper part of the breast has risen with above average rates in recent decades. Aluminium salts as ingredients in deodorants and antiperspirants are being absorbed by the body to a greater extent than hitherto assumed. Their toxicity for healthy and diseased breast tissue cells includ...

    A 62-year-old woman presented with a right breast tumor. Examination yielded a diagnosis of right breast cancer (T4bN3bM1[lung]). After right breast mastectomy for local control, 9 sessions of chemotherapy containing an anthracycline and taxane were administered. Because of progression of lung metastasis, bevacizumab and paclitaxel were administered. Follow-up computed tomography(CT)scans showed that the multiple solid lung metastases had reduced in size, but a hollowing effect was noted. Eight months later, the patient developed left pneumothorax. The origin of the pneumothorax was unclear, but the hollowing due to the lung metastases seen after bevacizumab treatment was thought to be the cause. The pneumothorax resolved after tube thoracostomy, but disease progression occurred because of the lack of chemotherapy, and the patient's general condition worsened. Although rare, we speculate that there is a risk of pneumothorax after bevacizumab- containing chemotherapy.

  13. Breast cancer in atomic bomb survivors

    International Nuclear Information System (INIS)

    Thirty eight years after the atomic bombings, studies of the Radiation Effects Research Foundation (RERF) on the extended Life Span Study (LSS) sample have continued to provide important information on radiation carcinogenesis. The third breast cancer survey among this sample revealed 564 cases during the period 1950-80, of which 412 were reviewed microscopically. The following statements reflect the conclusions from the current investigation; 1) the relationship between radiation dose and breast cancer incidence was consistent with linearity and did not differ markedly between the Hiroshima and Nagasaki survivors, 2) a dose-related breast cancer risk was observed among women who were in their first decade of life at the time of exposure, 3) the relative risk of radiationinduced breast cancer decreased with increasing age at exposure, 4) the pattern over time of age-specific breast cancer incidence is similar for exposed and control women (that is, exposed women have more breast cancer than control women but the excess risk closely follows normal risk as expressed by age-specific population rates), and 5) radiation-induced breast cancer appears to be morphologically similar to other breast cancer

    Common variation on 14q24.1, close to RAD51B, has been associated with breast cancer: rs999737 and rs2588809 with the risk of female breast cancer and rs1314913 with the risk of male breast cancer. The aim of this study was to investigate the role of RAD51B variants in breast cancer predisposition, particularly in the context of familial breast cancer in Finland. We sequenced the coding region of RAD51B in 168 Finnish breast cancer patients from the Helsinki region for identification of possible recurrent founder mutations. In addition, we studied the known rs999737, rs2588809, and rs1314913 SNPs and RAD51B haplotypes in 44,791 breast cancer cases and 43,583 controls from 40 studies participating in the Breast Cancer Association Consortium (BCAC) that were genotyped on a custom chip (iCOGS). We identified one putatively pathogenic missense mutation c.541C>T among the Finnish cancer patients and subsequently genotyped the mutation in additional breast cancer cases (n = 5259) and population controls (n = 3586) from Finland and Belarus. No significant association with breast cancer risk was seen in the meta-analysis of the Finnish datasets or in the large BCAC dataset. The association with previously identified risk variants rs999737, rs2588809, and rs1314913 was replicated among all breast cancer cases and also among familial cases in the BCAC dataset. The most significant association was observed for the haplotype carrying the risk-alleles of all the three SNPs both among all cases (odds ratio (OR): 1.15, 95% confidence interval (CI): 1.11–1.19, P = 8.88 x 10−16) and among familial cases (OR: 1.24, 95% CI: 1.16–1.32, P = 6.19 x 10−11), compared to the haplotype with the respective protective alleles. Our results suggest that loss-of-function mutations in RAD51B are rare, but common variation at the RAD51B region is significantly associated with familial breast cancer risk. PMID:27149063

    A functional DNA repair system has been identified as important in the prevention of tumour development. Previous studies have hypothesized that common polymorphisms in DNA repair genes could play a role in breast cancer risk and also identified the potential for interactions between these polymorphisms and established breast cancer risk factors such as physical activity. Associations with breast cancer risk for 99 single nucleotide polymorphisms (SNPs) from genes in ten DNA repair pathways were examined in a case-control study including both Europeans (644 cases, 809 controls) and East Asians (299 cases, 160 controls). Odds ratios in both additive and dominant genetic models were calculated separately for participants of European and East Asian ancestry using multivariate logistic regression. The impact of multiple comparisons was assessed by correcting for the false discovery rate within each DNA repair pathway. Interactions between several breast cancer risk factors and DNA repair SNPs were also evaluated. One SNP (rs3213282) in the gene XRCC1 was associated with an increased risk of breast cancer in the dominant model of inheritance following adjustment for the false discovery rate (P breast cancer risk or their modification by breast cancer risk factors were observed.

  19. Managing arthralgia in a postmenopausal woman taking an aromatase inhibitor for hormonesensitive early breast cancer: a case study

    International Nuclear Information System (INIS)

    In order to reduce the risk of recurrence, adjuvant treatment with an aromatase inhibitor (AI) is recommended for postmenopausal women following surgery for hormone receptor-positive breast cancer. AIs are associated with improved disease-free survival compared with tamoxifen. The adverse events associated with AIs resemble those of menopause, such as bone density loss and musculoskeletal symptoms. We examine the case of a postmenopausal woman who was prescribed anastrozole, a nonsteroidal AI, as adjuvant therapy following surgery for estrogen and progesterone receptor-positive (ER and PgR+) breast cancer. A 58-year-old postmenopausal woman diagnosed with ER and PgR+ breast cancer was prescribed anastrozole as adjuvant therapy following a right-inferior quadrantectomy. After experiencing joint pain and stiffness, she was prescribed paracetamol and a topical nonsteroidal anti-inflammatory drug. She was also counseled on nonpharmacological interventions. However, she continued to experience symptoms, and reported that she was not taking anastrozole regularly. The case study patient ultimately found relief by switching to letrozole, another aromatase inhibitor. This approach is supported by recent studies examining the benefits of switching strategies between aromatase inhibitors in order to relieve symptoms of arthralgia/myalgia. Both adherence and strategies for managing aromatase inhibitor-associated arthralgia are key to deriving maximal clinical benefit from AI therapy. Switching from one aromatase inhibitor to another may provide a viable option in managing adverse events and enhancing adherence to medication

    Full Text Available The present article describes the ongoing (partial remission of a female patient (41 years old from estrogen receptor (ER-positive/progesterone receptor (PR-negative metastatic breast cancer in response to a combination treatment directed towards the revitalization of the mitochondrial respiratory chain (oxidative phosphorylation, the suppression of NF-kappaB as a factor triggering the inflammatory response, and chemotherapy with capecitabine. The reduction of tumor mass was evidenced by a continuing decline of CA15-3 and CEA tumor marker serum levels and 18FDG-PET-CT plus magnetic resonance (MR imaging. It is concluded that such combination treatment might be a useful option for treating already formed metastases and for providing protection against the formation of metastases in ER positive breast cancer. The findings need to be corroborated by clinical trials. Whether similar results can be expected for other malignant tumor phenotypes relying on glycolysis as the main energy source remains to be elucidated.

    2016-01-01

    Vaginal cancer is a rare malignancy accounting for 1-2% of all pelvic neoplasms. Dissemination usually occurs through local invasion and rarely metastasises to distal locations. Metastasis of vaginal cancer to the breast is extremely infrequent and unique. A 66-year-old Asian woman presented with vaginal bleeding and was found to have a vaginal mass and a left breast mass. Pathological assessment of the biopsies revealed identical squamous cell characteristics of both masses. We describe a very rare and novel case of a distally located vaginal carcinoma with metastasis to the breast Federation of Gynecology and Obstetrics (FIGO) stage IV (FIGO IVB). Robot-assisted extrafascial total hysterectomy with local vaginal mass excision and partial mastectomy of the left breast were performed. After surgery, the patient underwent adjuvant chemotherapy followed by breast and pelvic radiotherapy, with maintained complete remission after 3 years of follow-up. This combination of findings and treatment is very distinct with a unique and favourable response. PMID:27444140

    Introduction The evidence on the relationship between breast cancer and different types of antihypertensive drugs taken for at least 5 years is limited and inconsistent. Furthermore, the debate has recently been fueled again with new data reporting an increased risk of breast cancer among women with a long history of use of antihypertensive drugs compared with nonusers. Methods In this case-control study, we report the antihypertensive drugs–breast cancer relationship in 1,736 breast cancer cases and 1,895 healthy controls; results are reported stratifying by the women’s characteristics (i.e., menopausal status or body mass index category) tumor characteristics and length of use of antihypertensive drugs. Results The relationship among breast cancer and use of calcium channel blockers (CCB) for 5 or more years had odds ratio (OR) = 1.77 (95% CI, 0.99 to 3.17). Stratifying by BMI, the OR increased significantly in the group with BMI ≥ 25 (OR 2.54, 95% CI, 1.24 to 5.22). CCBs were even more strongly associated with more aggressive tumors, (OR for invasive tumors = 1.96, 95% CI = 1.09 to 3.53; OR for non ductal cancers = 3.97, 95% CI = 1.73 to 9.05; OR for Erbb2+ cancer = 2.97, 95% CI: 1.20 to 7.32). On the other hand, premenopausal women were the only group in which angiotensin II receptor blockers may be associated with breast cancer (OR = 4.27, 95% CI = 1.32 to 13.84) but this could not be identified with any type or stage. Use of angiotensin-converting-enzyme inhibitors, beta blockers and diuretics were not associated with risk. Conclusions In this large population-based study we found that long term use of calcium channel blockers is associated with some subtypes of breast cancer (and with breast cancer in overweight women).

    Full Text Available Abstract Background Primary prevention of breast cancer through prophylactic mastectomy can reduce the risk of malignancy in high-risk individuals. No type of mastectomy completely removes all breast tissue, but a subcutaneous mastectomy leaves more tissue in situ than does a simple mastectomy. Case presentation We report a case of invasive breast cancer in a BRCA2-positive woman 33 years after bilateral subcutaneous mastectomy. To our knowledge, only one case of primary breast cancer after prophylactic mastectomy in a BRCA1-positive patient has been reported in the literature and none in BRCA2-positive individuals. Conclusion Careful documentation and long follow-up is essential to fully assess the benefits and risks of preventive surgical procedures in BRCA1 and BRCA2 mutation carriers.

  17. A Case-Control Study to Estimate the Impact of the Icelandic Population-Based Mammography Screening Program on Breast Cancer Death

    International Nuclear Information System (INIS)

    Background: The Icelandic breast cancer screening program, initiated November 1987 in Reykjavik and covering the whole country from December 1989, comprises biennial invitation to mammography for women aged 40-69 years old. Purpose: To estimate the impact of mammography service screening in Iceland on deaths from breast cancer. Material and Methods: Cases were deaths from breast cancer from 1990 onwards in women aged 40 and over at diagnosis, during the period November 1987 to December 31, 2002. Age- and screening-area-matched, population-based controls were women who had also been invited to screening but were alive at the time their case died. Results: Using conditional logistic regression on the data from 226 cases and 902 controls, the odds ratio for the risk of death from breast cancer in those attending at least one screen compared to those never screened was 0.59 (95% CI 0.41-0.84). After adjustment for healthy-volunteer bias and screening-opportunity bias, the odds ratio was 0.65 (95% CI 0.39-1.09). Conclusion: These results indicate a 35-40% reduction in breast cancer deaths by attending the Icelandic breast cancer screening program. These results are consistent with the overall evidence from other observational evaluations of mammography-based programs

  18. Screening for breast cancer in a high-risk series

    International Nuclear Information System (INIS)

    A unique cohort of women at increased risk of breast cancer because of prior X-ray treatment of acute mastitis and their selected high-risk siblings were offered periodic breast cancer screening including physical examination of the breasts, mammography, and thermography. Twelve breast cancers were detected when fewer than four would have been expected based on age-specific breast cancer detection rates from the National Cancer Institute/American Cancer Society Breast Cancer Demonstration Detection Projects. Mammography was positive in all cases but physical examination was positive in only three cases. Thermography was an unreliable indicator of disease. Given the concern over radiation-induced risk, use of low-dose technique and of criteria for participation that select women at high risk of breast cancer will maximize the benefit/risk ratio for mammography screening

    Breast cancer-related lymphedema is one of the complications resulting from treatment. It is defined as arm oedema in the breast cancer patients caused by interruption of the flow of the axillary lymphatic system from surgery or radiation therapy, which results in the accumulation of fluid in the subcutaneous tissue of the arm, with a decrease in tissue distensibility around the joints and an increased weight of the extremity. Decongestive lymphatic therapy is common management for lymphedema. A program combining skin care, manual lymphatic drainage, exercise, and compression therapy (multilayer bandage or garment) is recognised as the best practice in lymphedema management. Kinesio taping (KT) for lymphatic drainage is a new choice in the field of physical therapy. The material and the original concept of the taping technique were introduced by Dr Kenso Kase in 1973. K-tape had been designed to allow 30-40% longitudinal stretch. It is composed of 100% cotton fibers and acrylic heat sensitive glue. Development of the technique for its administration is still ongoing. The paper discusses the case of a woman with breast cancer, in whom lymphedema occurred. The patient had three weeks of therapy. The treatment consisted of 12 manual lymphatic drainage, 12 pneumatic compressions and 3 applications of the KT method (due to the lack of standard multi-layer bandaging). During the measurement of oedema it was noted that KT had a significant effect on the reduction of lymphedema and accelerates healing effects compared to standard methods.

    The purpose of this work is to give practical guidelines for radiotherapy of locally advanced, inflammatory and metastatic breast cancer at first presentation. A comprehensive survey of the literature using the search phrases ''locally advanced breast cancer'', ''inflammatory breast cancer'', ''breast cancer and synchronous metastases'', ''de novo stage IV and breast cancer'', and ''metastatic breast cancer'' and ''at first presentation'' restricted to ''clinical trials'', ''randomized trials'', ''meta-analysis'', ''systematic review'', and ''guideline'' was performed and supplemented by using references of the respective publications. Based on the German interdisciplinary S3 guidelines, updated in 2012, this publication addresses indications, sequence to other therapies, target volumes, dose, and fractionation of radiotherapy. International and national guidelines are in agreement that locally advanced, at least if regarded primarily unresectable and inflammatory breast cancer should receive neoadjuvant systemic therapy first, followed by surgery and radiotherapy. If surgery is not amenable after systemic therapy, radiotherapy is the treatment of choice followed by surgery, if possible. Surgery and radiotherapy should be administered independent of response to neoadjuvant systemic treatment. In patients with a de novo diagnosis of breast cancer with synchronous distant metastases, surgery and radiotherapy result in considerably better locoregional tumor control. An improvement in survival has not been consistently proven, but may exist in subgroups of patients. Radiotherapy is an important part in the treatment of locally advanced and inflammatory breast cancer that should be given to all patients regardless to the intensity and effect of

    Full Text Available Benign lymphoreticulosis (cat scratch disease, CSD may have a clinical course that varies from the most common lymphadenitis localized in the site of inoculation, preceded by the typical “primary lesion,” to a context of severe systemic involvement. Among these uncommon clinical aspects, there is mammarian granulomatous lymphadenitis which may appear as a mastitis or a solitary intraparenchymal mass, giving the impression of a breast tumor. In these cases, intensive clinical, instrumental, and laboratory investigations are necessary to exclude malignancy. Because of its rarity, in equivocal cases, it is reasonable to use surgical excision for accurate histological examination. We report a case of CSD of the breast in a 59-year-old woman, analyzing the clinical, histopathological, and instrumental appearance and also performing a literature review.

    OBJECTIVE Different mammographic features are probably predictive of different prognosis. However, ambiguity still exists in understanding the relationship between them. In resent years, digital mammography has been available for clinical use which has led to a revolution in the resolving of images and an increase in early-stage breast cancer detection.Based on the above knowledge, this study was performed to evaluate the relationship between full-field digital mammographic features and clinicopathologic characteristics in breast cancer.METHODS Digital mammograms of 176 patients with pathologically proven breast cancer were reviewed. Also, clinical and pathologic records (histological types and axillary lymph nodes status) were retrospectively examined.RESULTS Most of the patients with a solitary microcalcification were young women under the age of 50(84.4%), but the majority of the patients with microcalcifications complicated by a mass were elderly women. Microcalcifications detected by mammography occurred frequently in ductal carcinoma in situ (28.1%) and in early invasive carcinoma (15.6%). Breast cancers with expression of microcalcifications combined with a spiculate mass had a high metastatic rate of axillary lymph nodes (69.4%). A high metastatic rate of axillary lymph nodes was also found in the patients with solitary worm-like microcalcifications (57.1%), solitary spiculate mass (53.7%) and solitary non-worm-like microcalcifications (44.4%). Simple worm-like microcalcifications accompanied with metastasis of 4 to 9 axillary lymph nodes occurred in 42.9% of the(6/14) cases. The patients with microcalcifications combined by a spiculate mass and with metastasis of 4 to 9 axillary lymph nodes accounted for 27.8% (10/36) of the cases,and those with metastases of 10 and over accounted for 16.7% (6/36).CONCLUSION Solitary microcalcifications occur frequently in young women and are usually associated with early breast cancer. There is a close relationship

    Full Text Available Abstract Introduction Breast cancer is one of the most important health problems in the world and affects a great number of women over the entire globe. This group of tumors rarely presents as bilateral disease and, when it does happen, normally occurs within the same histological type. We report a rare case of concurrent bilateral breast cancer with two different histology types, a breast carcinoma and a breast sarcoma, in a 42-year-old woman referred to our hospital. Case presentation A 42-year-old Caucasian woman admitted to our institute in August 1999, presented with a nodule in the left breast of 3.0 × 2.5 cm, and, in the right breast, one of 1.0 cm, suspected of malignancy and with a clinically negative armpit. Biopsies had revealed invasive mammary carcinoma (right breast and sarcoma (left breast. She was submitted to bilateral modified radical mastectomy. A histological study showed an invasive mammary carcinoma degree II lobular pleomorphic type with invasion of seven of the 19 excised axillary nodes in the right breast and, in the left breast, a sarcoma of the mammary stroma, for which the immunohistochemistry study was negative for epithelial biomarkers and positive for vimentin. Later, she was submitted for chemotherapy (six cycles of 75 mg/m2 5-fluorouracil, epirubicin and cyclophosphamide followed by radiotherapy of the thoracic wall and axillary nodes on the left. Hormone receptors were positive in the tumor of the right breast, and tamoxifen, 20 mg, was prescribed on a daily basis (five years followed by letrozole, 2.5 mg, also daily (five years. She presented no sign of negative evolution in the last consultation. Conclusion The risk of development of bilateral breast cancer is about 1% each year within a similar histological type, but it is higher in tumors with lobular histology. In this case, the patient presented, simultaneously, two histologically distinct tumors, thus evidencing a rare situation.

    Full Text Available Congenital malformations of the breast appear in 10 % of the population. The existence of mammary tissue at any line of the breast is classified according to Kajava’s categories into eight classes which differ one from the other in the presence or absence of the areola of the breast, nipple and glandular tissue. This report presents a case of a puerpera who had delivered her child seven days before her attendance to hospital. She presented with discharge from her both axillae. On physical examination, a supernumerary nipple with milky secretion out from it was found in her right axilla and secretion throughout the contralateral axilla through the skin pores, with absence of nipple and areola in that axillary region. The echographic study revealed the presence of bilateral ectopic mammary tissue. This case belongs to Kajava’s class IV classification in the left axilla and a variery of Type I in the right axilla. In facing a mammary malformation, a conservative attitude seems to be the most appropriate although esthetics requires surgery. To keep into account the presence of supernumerary breasts will be a need for the prevention of breast cancer. This case has been presented due to all these reasons and the unusual features of this case.

    Globally, the burden of breast cancer (BC) continues to increase. BC related lymphedema (BCRL) is currently non curable and as a life time risk it affects at least 25% of BC patients. Knowing more about BCRL and appropriate control of its modifiable risk factors can improve quality of life (QOL) of the affected patients. In this case control study to detect factors, 400 women with BCRL (as the case group) and 283 patients with BC without lymphedema (as the control group) that were referred to Shiraz University of Medical Sciences affiliated BC clinic center were assessed. The data were analyzed in SPSS. The mean age of the case group was 52.3±11.0 years and of the control group was 50.1±10.9 years. In patients with BCRL, 203(50.7%) had left (Lt) side BC and in non- lymphedema group 151 (53.3%) had Lt side BC. Out of all BCRL patients, 204 (51%) had lymphedema in all parts of their affected upper extremities, 100 (25%) had swelling in the arm and forearm and 23 (5.7%) had edema in both the upper extremity and trunk. Edema, heaviness, concern about changing body image, pain and paresthesia were the most common signs/symptoms among patients with BCRL. In BCRL patients, the difference of circumference between the affected upper limb and non-affected limb was 4.4±2.5 cm and the difference in volume displacement was 528.7±374.4 milliliters. Multiple variable analysis showed that moderate to severe activity (OR; odds ratio =14, 95% CI: 2.6-73.3 ), invasiveness of BC (OR =13.7, 95% CI: 7.3-25.6), modified radical mastectomy (OR=4.3, 95% CI: 2.3-7.9), BMI =>25 (OR=4.2, 95% CI: 2-8.7), radiotherapy (OR=3.9, 95% CI: 1.8-8.2 ), past history of limb damage (OR=1.7, 95% CI: 0.9-3.1) and the number of excised lymph nodes (OR=1.06, 95% CI: 1.02-1.09) were the significant predictors of lymphedema in women with BC. Modifiable risk factors of BCRL such as non-guided moderate to severe physical activity, high BMI and trauma to the limb should be controlled as early as possible in

    Choline and betaine are essential nutrients involved in one-carbon metabolism and have been hypothesised to affect breast cancer risk. Functional polymorphisms in genes encoding choline-related one-carbon metabolism enzymes, including phosphatidylethanolamine N-methyltransferase (PEMT), choline dehydrogenase (CHDH) and betaine-homocysteine methyltransferase (BHMT), have important roles in choline metabolism and may thus interact with dietary choline and betaine intake to modify breast cancer risk. This study aimed to investigate the interactive effect of polymorphisms in PEMT, BHMT and CHDH genes with choline/betaine intake on breast cancer risk among Chinese women. This hospital-based case-control study consecutively recruited 570 cases with histologically confirmed breast cancer and 576 age-matched (5-year interval) controls. Choline and betaine intakes were assessed by a validated FFQ, and genotyping was conducted for PEMT rs7946, CHDH rs9001 and BHMT rs3733890. OR and 95 % CI were estimated using unconditional logistic regression. Compared with the highest quartile of choline intake, the lowest intake quartile showed a significant increased risk of breast cancer. The SNP PEMT rs7946, CHDH rs9001 and BHMT rs3733890 had no overall association with breast cancer, but a significant risk reduction was observed among postmenopausal women with AA genotype of BHMT rs3733890 (OR 0·49; 95 % CI 0·25, 0·98). Significant interactions were observed between choline intake and SNP PEMT rs7946 (P interaction=0·029) and BHMT rs3733890 (P interaction=0·006) in relation to breast cancer risk. Our results suggest that SNP PEMT rs7946 and BHMT rs3733890 may interact with choline intake on breast cancer risk.

  15. A population-based case-cohort study of the risk of myocardial infarction following radiation therapy for breast cancer

    International Nuclear Information System (INIS)

    Objective: To describe the risk of acute myocardial infarction (AMI) after radiation therapy (RT) for breast cancer (BrCa) in an exposed population. Methods: We identified and validated cases of AMI (vAMI), by electrocardiographic or enzyme criteria, among all 6680 women who received post-operative RT following lumpectomy or mastectomy, within 12 months following diagnosis of BrCa between 1982 and 1988 in Ontario, Canada. We identified women without vAMI whose death certification was ascribed to AMI (dAMI). We abstracted risk factors and treatment exposures for a random sample of women from the 6680, and for all with vAMI or dAMI. The hazards of vAMI and of dAMI were estimated using multivariate Cox proportional hazards models, corrected for study design. Results: We validated 121 cases of vAMI and identified 92 cases of dAMI. The risk of vAMI associated with RT to the left breast HR = 1.96 (1.09, 3.54) among women at age ≥ 60 at time of RT, adjusted for history of smoking and prior MI. The adjusted HR dAMI = 1.90 (1.08, 3.35) for exposure to anterior internal mammary node (IMC) RT. Among women who received anterior left breast boost RT, increasing area of the boost is associated with adjusted HR vAMI = 1.02 (1.00, 1.03)/cm2, and adjusted HR dAMI = 1.02 (1.01, 1.03)/cm2. Conclusion: The risks of vAMI and dAMI following RT for BrCa are related to anatomic sites of RT (left breast, area of anterior left breast boost field, and anterior IMC field)

    Full Text Available Background: Enzymes of the Glutathione S-transferase system (GST modulate the effects of exposure to several cytotoxic and genotoxic agents. Nitric oxide (NO is constitutively synthesized in the endothelium by endothelial nitric oxide synthase (eNOS and acts as a pleiotropic regulator involved in carcinogenesis. Vitamin D levels may influence breast cancer development. The vitamin D receptor (VDR is a crucial mediator for the cellular effects of vitamin D and additionally interacts with other cell-signaling pathways that influence cancer development. Objectives: To check for the association of polymorphisms of GST, eNOS3 and VDR genes with the susceptibility and severity of breast cancer in Egyptian cases. Subjects: This work included 100 cases with breast cancer and 100 healthy individuals. The mean age of cases was 48.31±11.40 years. They included 100 females.Methods: DNA was amplified using PCR-RFLP for detection of polymorphisms related to eNOS3 and VDR , also DNA was amplified using PCR-SSP for detection of polymorphisms related to GST and calculating the odds ratios and their 95% confidence intervals.Results: Total cases showed high significant frequency of eNOS3-786 CC (P<0.05, OR=18.58 genotypes, GSTT1(null (OR = 2.68; CI 95%=1.51-4.75; p=0.001. These were considered risk genotypes for disease susceptibility. On the other hand, total cases showed low significant frequency with homozygosity for eNOS3-786 TT (P=0.01 and the GSTT1 gene was present in 42.0% of the cancers and in 66.0% of controls (OR = 0.37; CI 95%= 0.21-0.66; p=0.001. These may be considered low risk genotypes. No significant difference in frequencies of null and present genotypes of GSTM1 and VDR FOKI in total cases compared to controls. Conclusions: Polymorphisms related to eNOS3-786, GSTT1 and VDR FOKI genes may be considered genetic markers for BC among Egyptian cases. This may have potential impact on family counselling as well as future management plans.

  20. Estrogens and breast cancer

    Full Text Available In this review, we summarize the epidemiologic evidence for the associations of oral contraceptives and postmenopausal hormones with risk of breast cancer. We also describe the biologic plausibility of these relationships. Overall, there appears to be little, if any, increase in risk with oral contraceptive use in general, even among users for 10 or more years. However, compared to never users, current oral contraceptive users appear to have a modest elevation in risk that subsides within about 10 years after cessation of use. For postmenopausal hormones, the weight of the evidence suggests little or no increase in risk among users of short duration, or for use in the past. However, current longer term use is associated with an increased risk of breast cancer that increases with duration. This increase in risk is large enough, and well enough supported, to be considered along with the other risks and benefits of postmenopausal hormone therapy.

    Although alcohol intake is an established risk factor for overall breast cancer, few studies have looked at the relationship between alcohol use and breast cancer risk by the four major subtypes of breast cancer and very few data exist in the alcohol-breast cancer relationship in Spanish women. A population-based case-control study was conducted in Galicia, Spain. A total of 1766 women diagnosed with invasive breast cancer between 1997 and 2014 and 833 controls participated in the study.

    A 46-year-old female underwent surgery for cancer of the right breast mammary (T3N2M0) in Sep 2010. Following post surgery, adjuvant chemotherapy of CAF regimens (cyclophosphamide+adriamycin+fluorouracil) was administered. Two years later, multiple pulmonary and skeletal metastatic lesions had been found by CT (computerized tomography) and ECT (emission computed tomograph) imaging. She received the treatment of second-line chemotherapy regimens of GP (cisplatin + gemcitabine). In the meantime, we administered Chinese traditional herb drugs (Fei Decoction, mixed a variety of effective herbal components) to help her recover from the poor condition. After taking the Chinese herbs for 2 months, the tumour marker (CEA, CA15-3) dramatically decreased, resulting in the normal range. Both lung and bone metastatic sites reduced according to CT and ECT imaging, and the patient felt free from the complaint of pulmonary and cardiac discomfort. Over time, the quality of life has been greatly improved, we have managed to prolong the PFS (progression-free-survival) and TTP (time-to-progression) from the onset to date. CTM (Chinese traditional medicine) considers human body as a dynamic platform in which all organs are correlative and bind each other. Relationship between heart, liver, spleen, lung and kidney is like an interlink between mother and son, and runs in cycle as a circle. In the course of this combined treatment, we showed that Chinese herbal medicine played an important role in the therapy of breast cancer. Chinese herbs might be an additional choice with their better benefits and tolerability in the treatment of recurrent breast cancer.

  3. Improved detection of breast cancer on FDG-PET cancer screening using breast positioning device

    International Nuclear Information System (INIS)

    The aim of this study was to investigate the detection rate of breast cancer by positron emission tomography cancer screening using a breast positioning device. Between January 2004 and January 2006, 1,498 healthy asymptomatic individuals underwent cancer screening by fluorine-18 fluorodeoxyglucose positron emission tomography (FDG-PET) at our institution; 660 of 1498 asymptomatic healthy women underwent breast PET imaging in the prone position using the breast positioning device to examine the mammary glands in addition to whole-body PET imaging. All subjects that showed abnormal 18F-FDG uptake in the mammary glands were referred for further examination or surgery at our institution or a local hospital. Our data were compared with the histopathological findings or findings of other imaging modalities in our institution and replies from the doctors at another hospital. Of the 660 participants, 7 (1.06%) were found to have breast cancers at a curable stage. All the seven cancers were detected by breast PET imaging, but only five of these were detected by whole-body PET imaging; the other two were detected by breast PET imaging using the breast positioning device. In cancer screening, prone breast imaging using a positioning device may help to improve the detection rate of breast cancer. However, overall cancer including mammography and ultrasonography screening should be performed to investigate the false-negative cases and reduce false-positive cases. The effectiveness of prone breast PET imaging in cancer screening should be investigated using a much larger number of cases in the near future. (author)

    2012-11-01

    Being a significant health problem that affects patients in various age groups, breast cancer has been extensively studied to date. Recently, molecular breast cancer classification has advanced significantly with the availability of genomic profiling technologies. Proteomic technologies have also advanced from traditional protein assays including enzyme-linked immunosorbent assay, immunoblotting and immunohistochemistry to more comprehensive approaches including mass spectrometry and reverse phase protein lysate arrays (RPPA). The purpose of this manuscript is to review the current protein markers that influence breast cancer prediction and prognosis and to focus on novel advances in proteomic classification of breast cancer.

    2012-06-01

    Full Text Available Abstract Background Li-Fraumeni-Syndrome (LFS is an autosomal-dominant, inherited tumour predisposition syndrome associated with heterozygous germline mutations in the TP53 gene. Patients with LFS are at a high risk to develop early-onset breast cancer and multiple malignancies, among which sarcomas are the most common. A high incidence of childhood tumours and close to 100% penetrance has been described. Knowledge of the genetic status of the TP53 gene in these patients is critical not only due to the increased risk of malignancies, but also because of the therapeutic implications, since a higher rate of radiation-induced secondary tumours in these patients has been observed. Case report We report a patient with LFS harbouring heterozygous, pathogenic TP53 germline mutation, who was affected by four synchronous malignancies at the age of 40: a myxofibrosarcoma of the right upper arm, bilateral breast cancer and a periadrenal liposarcoma. Radiological treatments and a surveillance program were adjusted according to recommendations for LFS patients. Conclusion Management of tumour treatment of patients with LFS is different to the general population because of their risk for secondary cancers in the radiation field. Screening procedures should take a possibly elevated risk for radiation induced cancer into account.

    Full Text Available Background: The axillary lymph node stage is one of the single most important determinants in the prognosis of breast cancer patients. The disadvantages of the two previous methods used for evaluating axillary node metastasis, i.e., axillary lymph node dissection and sentinel lymph node biopsy, have directed researchers to investigate new techniques for this purpose. The aim of the current study was to evaluate the clinical usefulness of axillary ultrasonography in detecting axillary metastasis. Methods: This study was conducted during a 12-month period. The breast cancer cases included in this study were all clinically diagnosed as stages I and II, with no prior treatment to the axillary region by surgery and/or chemo-radiotherapy. Excluded from the study group were patients with palpable axillary lymph nodes, those who had major organ failure or concomitant malignancy. All included patients with non-palpable axillary lymph nodes underwent axillary ultrasound examination. An ultrasound- guided core needle biopsy was performed on patients with suspected metastasis. Results: There were 125 female patients with a mean age of 49.6 years included in this study. From these, 16 (12.8% cases had positive axillary sonographic findings. Pathologic evaluation of tissue specimens (taken by ultrasound-guided core needle biopsy in 10 (62.5% out of 16 patients were positive, and in the patient group of 6 (37.5% cases, studies were negative. Axillary ultrasonography had a sensitivity of 35.7%, specificity of 93.8%, positive predictive value of 62.5%, and negative predictive value of 83.5%. Conclusion: The axillary ultrasonogram is a reliable technique in the determination of axillary nodal metastatic involvement in breast cancer patients. By use of this method a significant amount of complications and costs related to the previous techniques can be avoided.

  7. Searching for early breast cancer biomarkers by serum protein profiling of pre-diagnostic serum; a nested case-control study

    International Nuclear Information System (INIS)

    Serum protein profiles have been investigated frequently to discover early biomarkers for breast cancer. So far, these studies used biological samples collected at or after diagnosis. This may limit these studies' value in the search for cancer biomarkers because of the often advanced tumor stage, and consequently risk of reverse causality. We present for the first time pre-diagnostic serum protein profiles in relation to breast cancer, using the Prospect-EPIC (European Prospective Investigation into Cancer and nutrition) cohort. In a nested case-control design we compared 68 women diagnosed with breast cancer within three years after enrollment, with 68 matched controls for differences in serum protein profiles. All samples were analyzed with SELDI-TOF MS (surface enhanced laser desorption/ionization time-of-flight mass spectrometry). In a subset of 20 case-control pairs, the serum proteome was identified and relatively quantified using isobaric Tags for Relative and Absolute Quantification (iTRAQ) and online two-dimensional nano-liquid chromatography coupled with tandem MS (2D-nanoLC-MS/MS). Two SELDI-TOF MS peaks with m/z 3323 and 8939, which probably represent doubly charged apolipoprotein C-I and C3a des-arginine anaphylatoxin (C3adesArg), were higher in pre-diagnostic breast cancer serum (p = 0.02 and p = 0.06, respectively). With 2D-nanoLC-MS/MS, afamin, apolipoprotein E and isoform 1 of inter-alpha trypsin inhibitor heavy chain H4 (ITIH4) were found to be higher in pre-diagnostic breast cancer (p < 0.05), while alpha-2-macroglobulin and ceruloplasmin were lower (p < 0.05). C3adesArg and ITIH4 have previously been related to the presence of symptomatic and/or mammographically detectable breast cancer. We show that serum protein profiles are already altered up to three years before breast cancer detection

    Full Text Available Abstract Background Ataxia telangiectasia-mutated and Rad3-related (ATR is a member of the PIK-related family which plays, along with ATM, a central role in cell-cycle regulation. ATR has been shown to phosphorylate several tumor suppressors like BRCA1, CHEK1 and TP53. ATR appears as a good candidate breast cancer susceptibility gene and the current study was designed to screen for ATR germline mutations potentially involved in breast cancer predisposition. Methods ATR direct sequencing was performed using a fluorescent method while widely available programs were used for linkage disequilibrium (LD, haplotype analyses, and tagging SNP (tSNP identification. Expression analyses were carried out using real-time PCR. Results The complete sequence of all exons and flanking intronic sequences were analyzed in DNA samples from 54 individuals affected with breast cancer from non-BRCA1/2 high-risk French Canadian breast/ovarian families. Although no germline mutation has been identified in the coding region, we identified 41 sequence variants, including 16 coding variants, 3 of which are not reported in public databases. SNP haplotypes were established and tSNPs were identified in 73 healthy unrelated French Canadians, providing a valuable tool for further association studies involving the ATR gene, using large cohorts. Our analyses led to the identification of two novel alternative splice transcripts. In contrast to the transcript generated by an alternative splicing site in the intron 41, the one resulting from a deletion of 121 nucleotides in exon 33 is widely expressed, at significant but relatively low levels, in both normal and tumoral cells including normal breast and ovarian tissue. Conclusion Although no deleterious mutations were identified in the ATR gene, the current study provides an haplotype analysis of the ATR gene polymorphisms, which allowed the identification of a set of SNPs that could be used as tSNPs for large-scale association

    Full Text Available Background. The parotid gland is an unusual site for metastatic disease and when metastasis occurs, it commonly originates from head and neck primaries. Spread from distant infraclavicular sites such as the breast, into the parotid, is even more unusual with very few cases reported in the literature. Case Report. We describe the case of a 65-year-old woman presenting for a rapidly enlarging right parotid mass. She had a history of an invasive ductal carcinoma of the right breast and was disease-free in the past 6 years prior to her presentation. She was thereafter diagnosed as having a solitary parotid metastasis from breast origin. A total parotidectomy was done and she was referred for adjuvant radiotherapy. Conclusion. Any parotid metastasis should be investigated, especially in patients with a prior history of cancer where the possibility of metastasis, even if improbable, should be kept in mind. Fine needle aspiration biopsy (FNAB is the first diagnostic procedure to be done and immunocytochemistry can provide valuable information even if it is not always needed for diagnosis. Superficial parotidectomy when feasible with adjuvant radiotherapy is the preferred approach for solitary metastasis of the parotid. The prognosis, however, remains poor regardless of the treatment modality used.

    Life-style has a major influence on the incidence of breast cancer. To evaluate the effects of life-style related metabolic-endocrine factors on breast cancer risk we conducted a case-control study comparing 223 women aged 38 to 75 years presenting with operable (stage I or II) breast cancer and 441 women of the same age having no breast cancer, who participated in a population-based breast cancer screening program. Women reporting diabetes mellitus were excluded. Sera from 110 women of the same age group presenting with early stage melanoma, lymphoma or cervical cancer were used as a second 'other-cancer control group'. Serum levels of C-peptide were significantly higher in early breast cancer cases compared to controls. The same was found for the ratios C-peptide to glucose or C-peptide to fructosamine, indicating insulin resistance. Sex hormone binding globulin was inversely, triglycerides and available estradiol were positively related to C-peptide. Serum C-peptide levels were related to body mass index (BMI), and to waist/hip ratio (WHR), in particular in controls. However, the relative increase of C-peptide, C-peptide to glucose or C-peptide to fructosamine in cases was independent of BMI or WHR. The log relative risk was linearly related to the log C-peptide levels. Relative risk according to quintiles, and adjusted for age, family history, BMI and WHR, for women at the 80% level was 2.9 as compared with those at the 20% level for C-peptide. Elevated C-peptide or C-peptide to fructosamine values were not observed in the sera from women belonging to the 'other-cancer control group'. This study suggests that hyperinsulinemia with insulin resistance is a significant risk factor for breast cancer independent of general adiposity or body fat distribution. PMID:1399128

    Full Text Available Inflammatory cytokines within the tumor microenvironment are linked to progression in breast cancer. Interleukin- (IL- 19, part of the IL-10 family, contributes to a range of diseases and disorders, such as asthma, endotoxic shock, uremia, psoriasis, and rheumatoid arthritis. IL-19 is expressed in several types of tumor cells, especially in squamous cell carcinoma of the skin, tongue, esophagus, and lung and invasive duct carcinoma of the breast. In breast cancer, IL-19 expression is correlated with increased mitotic figures, advanced tumor stage, higher metastasis, and poor survival. The mechanisms of IL-19 in breast cancer have recently been explored both in vitro and in vivo. IL-19 has an autocrine effect in breast cancer cells. It directly promotes proliferation and migration and indirectly provides a microenvironment for tumor progression, which suggests that IL-19 is a prognostic marker in breast cancer and that antagonizing IL-19 may have therapeutic potential.

  14. Human Papilloma Viruses and Breast Cancer – Assessment of Causality

    Lawson, James Sutherland; Glenn, Wendy K.; Whitaker, Noel James

    2016-01-01

    High risk human papilloma viruses (HPVs) may have a causal role in some breast cancers. Case–control studies, conducted in many different countries, consistently indicate that HPVs are more frequently present in breast cancers as compared to benign breast and normal breast controls (odds ratio 4.02). The assessment of causality of HPVs in breast cancer is difficult because (i) the HPV viral load is extremely low, (ii) HPV infections are common but HPV associated breast cancers are uncommon, and (iii) HPV infections may precede the development of breast and other cancers by years or even decades. Further, HPV oncogenesis can be indirect. Despite these difficulties, the emergence of new evidence has made the assessment of HPV causality, in breast cancer, a practical proposition. With one exception, the evidence meets all the conventional criteria for a causal role of HPVs in breast cancer. The exception is “specificity.” HPVs are ubiquitous, which is the exact opposite of specificity. An additional reservation is that the prevalence of breast cancer is not increased in immunocompromised patients as is the case with respect to HPV-associated cervical cancer. This indicates that HPVs may have an indirect causal influence in breast cancer. Based on the overall evidence, high-risk HPVs may have a causal role in some breast cancers. PMID:27747193

    Part of the substantial unexplained familial aggregation of breast cancer may be due to interactions between common variants, but few studies have had adequate statistical power to detect interactions of realistic magnitude. We aimed to assess all two-way interactions in breast cancer susceptibility between 70 917 single nucleotide polymorphisms (SNPs) selected primarily based on prior evidence of a marginal effect. Thirty-eight international studies contributed data for 46 450 breast cancer cases and 42 461 controls of European origin as part of a multi-consortium project (COGS). First, SNPs were preselected based on evidence (P 10−10). In summary, we observed little evidence of two-way SNP interactions in breast cancer susceptibility, despite the large number of SNPs with potential marginal effects considered and the very large sample size. This finding may have important implications for risk prediction, simplifying the modelling required. Further comprehensive, large-scale genome-wide interaction studies may identify novel interacting loci if the inherent logistic and computational challenges can be overcome. PMID:24242184

    The comparable diagnostic accuracy of {sup 99m}Tc-sestamibi scintimammogram (SM) in patients with dense and fatty breasts was reported in the U. S and Canadian multicenter clinical trials (JNM 37 : p74-75, 1996). This is not the case with mammography which misses breast cancer in dense breasts often. The reported incidence of dense breast among Korean is about 50% as opposed to 25% in western population seen on mammograms. Therefore, dense breast would be more problematic in the evaluation of breast cancer among Korean. Thirty five highly selected patients with breast mass and 2 patients after silicon mammoplasty were evaluated by sonography (US), mammography (Mam) and SM. The patient's age ranged from 28 to 40 (average 34.6). Each patient received 20 mCi of {sup 99m}Tc MIBI intravenously and in 5-10 min simultaneous prone lateral views were obtained for 10 min followed by a supine anterior view with arms up for 10 min. Interpretive criteria of breast cancer by SM was any focal increased uptake (mild-marked) within the breast (single or multiple). In two patients with silicon mammoplasty, US and Mam were not useful while SM excluded breast cancer although small (> 1.0 cm) lesion could not be completely excluded. In 19 patients with biopsy confirmed carcinoma (larger than 1.5 cm), The results of three modalities were the following. The remaining 15 patients considered to have benign diseases (76% by Mam, 93% by US, 93% by SM) and are being followed at the surgical clinic. In conclusion, SM is very useful in the evaluation of breast mass in highly selected patients with dense breast which is more common among Korean and in patients after silicon augmentation. Therefore, SM should be used more often in patients (especially young) with dense breast and after mammoplasty than mammography in the detection of breast cancer.

    Full Text Available A 46-year-old Korean woman was diagnosed with stage III breast cancer and underwent 8 cycles of neoadjuvant chemotherapy, breast conservation surgery and adjuvant radiotherapy. However, the cancer recurred in the right upper lung (RUL and the right pulmonary hilum after 8 months. The RUL nodule was removed through a wedge resection, and the pathologic finding was revealed as a metastatic adenocarcinoma. Adjuvant chemotherapy was recommended, but she refused it because she feared adverse reactions to chemotherapy. Instead, Korean Medicine Therapy with intravenous wild ginseng pharmacopuncture (WGP, Cordyceps sinensis pharmacopuncture, Trichosanthes kirilowii pharmacopuncture, Euonymus alatus pharmacopuncture (EAP and Astragalus membranaceus pharmacopuncture was started. After a month, the disease looked stable, but findings of newly occurring metastatic lymphadenopathies appeared on CT after 6 months. Salvage chemotherapy was recommended, but she also refused it. At this time, Prunella vulgaris pharmacopuncture was started. Finally, a complete resolution was confirmed on PET-CT after 5 months, and she has remained in stable condition for more than 6 months with WGP, EAP, a Soram nebulizer solution inhalation and the oral intake of Soramdan S and Hangamdan S.

    Purpose and approach: to report a case of morphea (localized scleroderma) in a patient following breast cancer therapy and to summarize the current literature. Results and conclusion: the occurrence of morphea is an unexpected late effect (approximately 1 year after the end of radiation therapy) which occurs frequently in the irradiated breast in women with breast-conserving therapy. The pathogenesis is unclear. The main differential diagnoses are recurrence of carcinoma and a radiogenic subcutaneous fibrosis (in most cases, the final diagnosis can only be made by means of a biopsy). Diagnosis and therapy must be performed in cooperation between dermatologist and radiooncologist. (orig.)

    Although alcohol intake is an established risk factor for overall breast cancer, few studies have looked at the relationship between alcohol use and breast cancer risk by the four major subtypes of breast cancer and very few data exist in the alcohol-breast cancer relationship in Spanish women. A population-based case-control study was conducted in Galicia, Spain. A total of 1766 women diagnosed with invasive breast cancer between 1997 and 2014 and 833 controls participated in the study. Data on demographics, breast cancer risk factors, and clinico-pathological characteristics were collected. We examined the alcohol-breast cancer association according to the major breast cancer subtypes [hormone-receptor-positive, HER2-negative (luminal A); hormone-receptor-positive, HER2-positive (luminal B); hormone-receptor-negative, HER2-negative (TNBC); and hormone-receptor-negative, HER2-positive (HER2 overexpressing)] as well as grade and morphology in Spanish women. With the exception of HER2 overexpressing, the risk of all subtypes of breast cancer significantly increased with increasing alcohol intake. The association was similar for hormonal receptor positive breast cancer, i.e., luminal A and luminal B breast cancer (odds ratio, OR 2.16, 95 % confidence interval, CI 1.55-3.02; and OR 1.98, 95 % CI 1.11-3.53, respectively), and for TNBC (TNBC: OR 1.93, 95 % CI 1.07-3.47). The alcohol-breast cancer association was slightly more pronounced among lobular breast cancer (OR 2.76, 95 % CI 1.62-4.69) than among ductal type breast cancers (OR 2.21, 95 % CI 1.61-3.03). In addition, significant associations were shown for all grades, I, II and III breast cancer (OR 1.98, 95 % CI 1.26-3.10; OR 2.34, 95 % CI 1.66-3.31; and OR 2.16, 95 % CI 1.44-3.25 for Grades I, II and III, respectively). To our knowledge, this is the first study to examine the association of breast cancer subtypes and alcohol intake in Spanish women. Our findings indicate that breast cancer risk increased

    Breast density, as assessed by mammography, reflects breast tissue composition. Breast epithelium and stroma attenuate x-rays more than fat and thus appear light on mammograms while fat appears dark. In this review, we provide an overview of selected areas of current knowledge about the relationship between breast density and susceptibility to breast cancer. We review the evidence that breast density is a risk factor for breast cancer, the histological and other risk factors that are associat...

    Breast cancer is one of the most common cancers with greater than 1,300,000 cases and 450,000 deaths each year worldwide. The development of breast cancer involves a progression through intermediate stages until the invasive carcinoma and finally into metastatic disease. Given the variability in clinical progression, the identification of markers that could predict the tumor behavior is particularly important in breast cancer. The determination of tumor markers is a useful tool for clinical m...

    Clinical management of breast cancer relies on case stratification, which increasingly employs molecular markers. The motivation behind delineating breast epithelial differentiation is to better target cancer cases through innate sensitivities bequeathed to the cancer from its normal progenitor state. A combination of histopathological and molecular classification of breast cancer cases suggests a role for progenitors in particular breast cancer cases. Although a remarkable fraction of the re...

    We performed digital subtraction angiography (DSA) on 42 patients with breast diseases to investigate its efficiency. As a result we came to the following conclusions: 1. The sensitivity was well evaluated in intraarterial digital subtraction angiography (IA-DSA) of breast. 2. IA-DSA could diagnose difficult cases like cancer which had undergone augmentation mammoplasty, or like Paget's disease and others. 3. DSA was a safe examination method. 4. The sensitivity of IA-DSA of breast cancer is superior to intravenous digital subtraction angiography (IV-DSA).

  9. A case-control study of the HER2 Ile655Val polymorphism in relation to risk of invasive breast cancer

    International Nuclear Information System (INIS)

    Overexpression of the HER2 proto-oncogene in human cancer cells has been associated with a poor prognosis, and survival improves with therapy targeting the HER2 gene. Animal studies and protein modeling suggest that the Ile655Val polymorphism located in the transmembrane domain of the HER2 protein might influence breast cancer development by altering the efficiency of homodimerization. To investigate this genetic polymorphism, incident cases of invasive breast cancer (N = 1,094) and population controls of a similar age (N = 976) were interviewed during 2001 to 2003 regarding their risk factors for breast cancer. By using DNA collected from buccal samples mailed by the participants, the HER2 Ile655Val polymorphism was evaluated with the Applied Biosystems allelic discrimination assay. Odds ratios (ORs) and 95% confidence intervals (95% CIs) were estimated by logistic regression adjusted for numerous breast cancer risk factors. Analysis was restricted to women with self-reported European descent. Prevalence of the Val/Val genotype was 5.6% in cases and 7.1% in controls. In comparison with the Ile/Ile genotype, the Ile/Val genotype was not significantly associated with breast cancer risk (OR 0.97, 95% CI 0.79 to 1.18), whereas the Val/Val genotype was associated with a reduced risk (OR 0.63, 95% CI 0.42 to 0.92). This inverse association seemed strongest in older women (OR 0.51, 95% CI 0.29 to 0.89 for women aged more than 55 years), women without a family history of breast cancer (OR 0.54, 95% CI 0.35 to 0.84), postmenopausal women with greater body mass index (OR 0.43, 95% CI 0.20 to 0.91 for a body mass index of 25.3 kg/m2 or more), and cases diagnosed with non-localized breast cancer (OR 0.49, 95% CI 0.26 to 0.90). Although results from our population-based case-control study show an inverse association between the HER2 Ile655Val polymorphism and risk of invasive breast cancer, most other studies of this single-nucleotide polymorphism suggest an overall null

    The increasing availability of electronic health records (EHRs) creates opportunities for automated extraction of information from clinical text. We hypothesized that natural language processing (NLP) could substantially reduce the burden of manual abstraction in studies examining outcomes, like cancer recurrence, that are documented in unstructured clinical text, such as progress notes, radiology reports, and pathology reports. We developed an NLP-based system using open-source software to process electronic clinical notes from 1995 to 2012 for women with early-stage incident breast cancers to identify whether and when recurrences were diagnosed. We developed and evaluated the system using clinical notes from 1,472 patients receiving EHR-documented care in an integrated health care system in the Pacific Northwest. A separate study provided the patient-level reference standard for recurrence status and date. The NLP-based system correctly identified 92% of recurrences and estimated diagnosis dates within 30 days for 88% of these. Specificity was 96%. The NLP-based system overlooked 5 of 65 recurrences, 4 because electronic documents were unavailable. The NLP-based system identified 5 other recurrences incorrectly classified as nonrecurrent in the reference standard. If used in similar cohorts, NLP could reduce by 90% the number of EHR charts abstracted to identify confirmed breast cancer recurrence cases at a rate comparable to traditional abstraction.

    Breast magnetic resonance imaging (MRI) is recommended as an adjunct to mammography for women who are considered at elevated risk of developing breast cancer. As a key component of breast MRI, dynamic contrast-enhanced MRI (DCE-MRI) uses a contrast agent to provide high intensity contrast between breast tissues, making it sensitive to tissue composition and vascularity. Breast DCE-MRI characterizes certain physiologic properties of breast tissue that are potentially related to breast cancer risk. Studies have shown that increased background parenchymal enhancement (BPE), which is the contrast enhancement occurring in normal cancer-unaffected breast tissues in post-contrast sequences, predicts increased breast cancer risk. Signal enhancement ratio (SER) computed from pre-contrast and post-contrast sequences in DCE-MRI measures change in signal intensity due to contrast uptake over time and is a measure of contrast enhancement kinetics. SER quantified in breast tumor has been shown potential as a biomarker for characterizing tumor response to treatments. In this work we investigated the relationship between quantitative measures of SER and breast cancer risk. A pilot retrospective case-control study was performed using a cohort of 102 women, consisting of 51 women who had diagnosed with unilateral breast cancer and 51 matched controls (by age and MRI date) with a unilateral biopsy-proven benign lesion. SER was quantified using fully-automated computerized algorithms and three SER-derived quantitative volume measures were compared between the cancer cases and controls using logistic regression analysis. Our preliminary results showed that SER is associated with breast cancer risk, after adjustment for the Breast Imaging Reporting and Data System (BI-RADS)-based mammographic breast density measures. This pilot study indicated that SER has potential for use as a risk factor for breast cancer risk assessment in women at elevated risk of developing breast cancer.

    We investigated if associations of breast density and breast cancer differ according to the level of other known breast cancer risk factors, including body mass index (BMI), age at menarche, parity, age at first child's birth, age at menopause, alcohol consumption, a family history of breast cancer, a history of benign breast disease, and physical activity. This study included 1,044 postmenopausal incident breast cancer cases diagnosed within the Nurses' Health Study cohort and 1,794 matched controls. Percent breast density, absolute dense, and non-dense areas were measured from digitized film images with computerized techniques. Information on breast cancer risk factors was obtained prospectively from biennial questionnaires. Percent breast density was more strongly associated with breast cancer risk in current postmenopausal hormone users (≥50 vs. 10 %: OR 5.34, 95 % CI 3.36-8.49) as compared to women with past (OR 2.69, 95 % CI 1.32-5.49) or no hormone history (OR 2.57, 95 % CI 1.18-5.60, p-interaction = 0.03). Non-dense area was inversely associated with breast cancer risk in parous women, but not in women without children (p-interaction = 0.03). Associations of density with breast cancer risk did not differ by the levels of BMI, age at menarche, parity, age at first child's birth, age at menopause, alcohol consumption, a family history of breast cancer, a history of benign breast disease, and physical activity. Women with dense breasts, who currently use menopausal hormone therapy are at a particularly high risk of breast cancer. Most breast cancer risk factors do not modify the association between mammographic breast density and breast cancer risk.

    Background: Logistic regression is one of the most widely used models to analyze the relation between one or more explanatory variables and a categorical response in the field of epidemiology, health and medicine. When there is strong correlation among explanatory variables, i.e.multicollinearity, the efficiency of model reduces considerably. The objective of this research was to employ latent variables to reduce the effect of multicollinearity in analysis of a case-control study about breast cancer risk factors.

    Methods: The data belonged to a case-control study in which 300 women with breast cancer were compared to same number of controls. To assess the effect of multicollinearity, five highly correlated quantitative variables were selected. Ordinary logistic regression with collinear data was compared to two models contain latent variables were generated using either factor analysis or principal components analysis. Estimated standard errors of parameters were selected to compare the efficiency of models. We also conducted a simulation study in order to compare the efficiency of models with and without latent factors. All analyses were carried out using S-plus.

    Results: Logistic regression based on five primary variables showed an unusual odds ratios for age at first pregnancy (OR=67960, 95%CI: 10184-453503 and for total length of breast feeding (OR=0. On the other hand the parameters estimated for logistic regression on latent variables generated by both factor analysis and principal components analysis were statistically significant (P<0.003. Their standard errors were smaller than that of ordinary logistic regression on original variables. The simulation showed that in the case of normal error and 58% reliability the logistic regression based on latent variables is more efficient than that model for collinear variables.

    2009-07-01

    Full Text Available Abstract Introduction Multiple distinct tumors arising in a single individual or within members of a family raise the suspicion of a genetic susceptibility disorder. Case presentation We present the case of a 52-year-old Caucasian woman diagnosed with sebaceous gland carcinoma of the eyelid, followed several years later with subsequent diagnoses of breast cancer and papillary carcinoma of the thyroid. Although the patient was also exposed to radiation from a pipe used in the oil field industry, the constellation of neoplasms in this patient suggests the manifestation of a known hereditary susceptibility cancer syndrome. However, testing for the most likely candidates such as Muir-Torre and Cowden syndrome proved negative. Conclusion We propose that our patient's clustering of neoplasms either represents a novel cancer susceptibility disorder, of which sebaceous gland carcinoma is a characteristic feature, or is a variant of the Muir-Torre syndrome.

    Asian women, including Korean, have a relatively higher incidence of dense breast tissue, compared with western women. Dense breast tissue has a lower sensitivity for the detection of breast cancer and a higher relative risk for breast cancer, compared with fatty breast tissue. Thus, there were limitations in the mammographic screening for women with dense breast tissue, and many studies for the supplemental screening methods. This review included appropriate screening methods for Korean women with dense breasts. We also reviewed the application and limitation of supplemental screening methods, including breast ultrasound, digital breast tomosynthesis, and breast magnetic resonance imaging; and furthermore investigated the guidelines, as well as the study results.

    International Nuclear Information System (INIS)

    The conservative treatment of early breast cancer always requires irradiation of residual mammary tissue. The preliminary results obtained in 45 early breast cancer patients, who received quadrantectomy plus axillary dissection, followed by radiation of residual breast are reported. Radiation was performed by the two opposed field technique. In some cases the residual breast tissue was compressed using a special accessory provided with the Theratron 780. In addition to the tumor dose of 50 GY, 10 GY boots was added to the surgical scar using 7 MeV electrons. The 6 patients with positive axillary nodes received 6 courses of adjuvant chemotherapy (CMF) after radiotherapy. All patients are currently alive and free of disease. The 64% (29 patients) were followed up for at least 5 years, and 36% (16 patients) for at least 3 years. Only 2 cases of local recurrence were encountered (4,4%). The esthetic result was satisfactory in all cases. No side effects due to treatment were noted

    Full Text Available Abstract Background A recent genome wide case-control association study identified NuMA region on 11q13 as a candidate locus for breast cancer susceptibility. Specifically, the variant Ala794Gly was suggested to be associated with increased risk of breast cancer. Methods In order to evaluate the NuMa gene for breast cancer susceptibility, we have here screened the entire coding region and exon-intron boundaries of NuMa in 92 familial breast cancer patients and constructed haplotypes of the identified variants. Five missense variants were further screened in 341 breast cancer cases with a positive family history and 368 controls. We examined the frequency of Ala794Gly in an extensive series of familial (n = 910 and unselected (n = 884 breast cancer cases and controls (n = 906, with a high power to detect the suggested breast cancer risk. We also tested if the variant is associated with histopathologic features of breast tumors. Results Screening of NuMA resulted in identification of 11 exonic variants and 12 variants in introns or untranslated regions. Five missense variants that were further screened in breast cancer cases with a positive family history and controls, were each carried on a unique haplotype. None of the variants, or the haplotypes represented by them, was associated with breast cancer risk although due to low power in this analysis, very low risk alleles may go unrecognized. The NuMA Ala794Gly showed no difference in frequency in the unselected breast cancer case series or familial case series compared to control cases. Furthermore, Ala794Gly did not show any significant association with histopathologic characteristics of the tumors, though Ala794Gly was slightly more frequent among unselected cases with lymph node involvement. Conclusion Our results do not support the role of NuMA variants as breast cancer susceptibility alleles.

  9. Evidence based radiation oncology: Breast cancer

    International Nuclear Information System (INIS)

    Purpose: Radiotherapy is, similar to surgery, a local treatment. In the case of breast cancer, it is generally given after conservative or after more extensive, tumour and patient adapted, surgery. The target volumes can be the breast and/or the thoracic wall and/or the regional lymph node areas. The integration and the extent of radiotherapy as part of the comprehensive treatment of the breast cancer patient, including the amount of surgery and the sequencing with the systemic treatments, has to be well discussed with all medical specialists involved in treating breast cancer on a multidisciplinary basis. Guidelines for the appropriate prescription and execution of radiotherapy are of utmost importance. However, individualisation based on the individual patients' and tumours' characteristics should always be envisaged. Materials and methods: Based on a review of the literature the level of evidence that is available for the indications for radiotherapy is summarised, as well as the main clinical questions that are unanswered today. An overview of the recent and ongoing clinical trails in breast cancer will highlight some of the current ongoing debates. Conclusions: In the case of breast cancer, radiotherapy, given after as well conservative as extensive risk-adapted surgery, significantly reduces the risk of local and regional recurrences. Especially for patients with an intermediate to high absolute risk for local recurrences, a positive influence on overall survival has been shown, notably when appropriate radiotherapy techniques are used. Most important is that the best results that we can offer to our breast cancer patients for all clinical endpoints (local and regional control; quality of life; cosmetic results; survival) can be obtained by a multidisciplinary and patient-oriented approach, involving all those involved in the treatment of breast cancer patients

    Full Text Available BACKGROUND: The association between polymorphisms on 5p12 and breast cancer (BC has been widely evaluated since it was first identified through genome-wide association approach; however, the studies have yielded contradictory results. We sought to investigate this inconsistency by performing a comprehensive meta-analysis on two wildly studied polymorphisms (rs10941679 and rs4415084 on 5p12. METHODS: Databases including Pubmed, EMBASE, Web of Science, EBSCO, and Cochrane Library databases were searched to find relevant studies. Odds ratios (ORs with 95% confidence intervals (CIs were used to assess the strength of association. The random-effects model was applied, addressing heterogeneity and publication bias. RESULTS: A total of 19 articles involving 100,083 cases and 163,894 controls were included. An overall random-effects per-allele OR of 1.09 (95% CI: 1.06-1.12; P = 4.5 × 10(-8 and 1.09 (95% CI: 1.05-1.12; P = 4.2 × 10(-7 was found for the rs10941679 and rs4415084 polymorphism respectively. Significant results were found in Asians and Caucasians when stratified by ethnicity; whereas no significant associations were found among Africans/African-Americans. Similar results were also observed using dominant or recessive genetic models. In addition, we find both rs4415084 and rs10941679 conferred significantly greater risks of ER-positive breast cancer than of ER-negative tumors. CONCLUSIONS: Our findings demonstrated that rs10941679-G allele and rs4415084-T allele might be risk-conferring factors for the development of breast cancer, especially in Caucasians and East-Asians.

  11. Evaluation of the effectiveness of kinesio taping application in a patient with secondary lymphedema in breast cancer: a case report

    Full Text Available Breast cancer-related lymphedema is one of the complications resulting from treatment. It is defined as arm oedema in the breast cancer patients caused by interruption of the flow of the axillary lymphatic system from surgery or radiation therapy, which results in the accumulation of fluid in the subcutaneous tissue of the arm, with a decrease in tissue distensibility around the joints and an increased weight of the extremity. Decongestive lymphatic therapy is common management for lymphedema. A program combining skin care, manual lymphatic drainage, exercise, and compression therapy (multilayer bandage or garment is recognised as the best practice in lymphedema management. Kinesio taping (KT for lymphatic drainage is a new choice in the field of physical therapy. The material and the original concept of the taping technique were introduced by Dr Kenso Kase in 1973. K-tape had been designed to allow 30-40% longitudinal stretch. It is composed of 100% cotton fibers and acrylic heat sensitive glue. Development of the technique for its administration is still ongoing. The paper discusses the case of a woman with breast cancer, in whom lymphedema occurred. The patient had three weeks of therapy. The treatment consisted of 12 manual lymphatic drainage, 12 pneumatic compressions and 3 applications of the KT method (due to the lack of standard multi-layer bandaging. During the measurement of oedema it was noted that KT had a significant effect on the reduction of lymphedema and accelerates healing effects compared to standard methods.

  15. Advancement flaps are enough in most cases as onco plastic technique for breast cancer even with central or periareolar localisation

    International Nuclear Information System (INIS)

    I have read with great interest khafagy et all s article in ENC1 2012:24:91-6 This small series needs explanations for following questions: 1- Thirteen cases with N0 have been operated by a complete axillary dissection. Would it be better to undertake sentinel lymph node biopsy (SLNB) in these cases? 2- The patients with periareolar tumor localization (half of the patients) underwent needlessly a pedicled flap operation instead of an advancement flap or simple rotation flap. They are simple and therefore less time-consuming onco plastic procedures. They do not require whole nippleareola complex excision. Therefore, advancement flaps or periareolar mastopexy [1] were more reasonable. 3- Ten patients with N2 represent locally advanced cancer of breast (Stage III). They should be treated by primary chemotherapy instead of surgery first. It needs explanation. 4- Four cases with N+ have not been given adjuvant chemotherapy. It should be explained. 5- The rates of good cosmetic results were the same for both patients and doctors. But in the literature, the rates of health professionals are nearly always lower than patients [2], It needs explanation. 6- The condition of contralateral breasts has not been presented. Is not there some cases requiring contralateral mastoplasty, reduction or any other cosmetic procedure? Kind regards.

  16. Ovarian stimulation in patients with breast cancer.

    Breast cancer is the most prevalent malignancy among women under 50. Improvements in diagnosis and treatment have yielded an important decrease in mortality in the last 20 years. In many cases, chemotherapy and radiotherapy develop side effects on the reproductive function. Therefore, before the anti-cancer treatment impairs fertility, clinicians should offer some techniques for fertility preservation for women planning motherhood in the future. In order to obtain more available oocytes for IVF, the ovary must be stimulated. New protocols which prevent exposure to increased estrogen during gonadotropin stimulation, measurements to avoid the delay in starting anti-cancer treatment or the outcome of ovarian stimulation have been addressed in this review. There is no evidence of association between ovarian stimulation and breast cancer. It seems that there are more relevant other confluent factors than ovarian stimulation. Factors that can modify the risk of breast cancer include: parity, age at full-term birth, age of menarche, and family history. There is an association between breast cancer and exogenous estrogen. Therefore, specific protocols to stimulate patients with breast cancer include anti-estrogen agents such as letrozole. By using letrozole plus recombinant follicular stimulating hormone, patients develop a multifollicular growth with only a mild increase in estradiol serum levels. Controlled ovarian stimulation (COS) takes around 10 days, and we discuss new strategies to start COS as soon as possible. Protocols starting during the luteal phase or after inducing the menses currently prevent a delay in starting ovarian stimulation. Patients with breast cancer have a poorer response to COS compared with patients without cancer who are stimulated with conventional protocols of gonadotropins. Although many centres offer fertility preservation and many patients undergo ovarian stimulation, there are not enough studies to evaluate the recurrence, breast cancer

  17. Positive margins and intraductal cancer does not impact local control in treating early stage breast cancer conservatively: a study of 902 cases

    International Nuclear Information System (INIS)

    Purpose: We have retrospectively reviewed our community setting cancer center's 14 year experience treating early stage breast cancer (T1, T2, N0, N1) with lumpectomy and post operative (post-op) irradiation (XRT) to determine if the presence of microscopically positive margins and/or intraductal cancer has an impact on local control. Materials and Methods: Between January 1, 1981 and December 31, 1994, 902 consecutive early stage breast cancers were treated with lumpectomy and post-op XRT, totaling 4500 cGy to the whole breast with a 1500 cGy boost to the tumor bed, for a total dose to the tumor bed of 6000 cGy. The presence or absence of microscopically positive margins, pure intraductal tumor and/or minimal (min) or extensive (ext) intraductal component (IDC) associated with an invasive tumor was determined if recorded on the pathology report. If not specifically recorded, the slides were reviewed by our pathologist (one of the authors) and a determination was made. Due to the absence of inking of the specimen and or sending the specimen in pieces, 30 of the tumors were listed as indeterminate. We defined min IDC as less than 25% of the invasive tumor containing intraductal cancer, and ext IDC as greater than 25%. Our average follow up was 5 years (yrs) with a range from 3 months to 15 yrs. Results: Stratification of our cases showed 614 (68%) breasts had T1, 208 (23%) T2, and 80 (9%) pure intraductal tumors. Analysis of the invasive tumors revealed 216 (29%) tumors with min IDC, and 72 (8%) with ext IDC. We identified 251 (28%) with microscopically positive margins that were equally dispersed between the T1, T2 and pure intraductal and invasive tumors with min and ext IDC. The Kaplan-Meier method was used to calculate local control in breasts with tumor having microscopically positive margins which was 95% and 85% at 5 and 10 yrs and for microscopically negative margins 96% and 89% at 5 and 10 yrs. Similar method was used to calculate local control in breasts

    This manifesto was prepared by a European Breast Cancer (EBC) Council working group and launched at the European Breast Cancer Conference in Glasgow on 20 March 2014. It sets out optimal technical and organisational requirements for a breast cancer pathology service, in the light of concerns about variability and lack of patient-centred focus. It is not a guideline about how pathology services should be performed. It is a call for all in the cancer community--pathologists, oncologists, patient advocates, health administrators and policymakers--to check that services are available that serve the needs of patients in a high quality, timely way.

  19. Spontaneous pneumothorax after radiation therapy for breast cancer. A case report

    International Nuclear Information System (INIS)

    A 41-year-old asymptomatic woman was referred to our hospital for a right pneumothorax noted incidentally on a chest radiograph. She had undergone surgery, radiation at a total dose of 60 Gy, and adjuvant chemotherapy therapy for right breast cancer 14 months previously. A chest tube was inserted into the right pleural cavity. Although the right lung expanded immediately, air leakage increased gradually and the right lung collapsed again three days after drainage. Computed tomography (CT) revealed the thickening of the frontal pleura of the right lower lobe, which resulted from radiation therapy, with chest tube compression and no blebs. We selected video-assisted thoracic surgery (VATS). The thoracoscopic view showed air leakage from the pleural fissures compressed by the chest tube. Plication was performed for this lesion and air leakage was stopped. No findings of recurrence have been noted since the operation. (author)

  20. Radiologic aspects of breast cancers detected through a breast cancer screening program

    International Nuclear Information System (INIS)

    Early detection in breast cancer and reduced mortality in women with this disease is today attributed to widespread use of mammography. High-quality performance is essential in all steps of breast cancer screening programs in order to avoid unnecessary anxiety and surgery in the women concerned. This report presents radiologic aspects of screening cancers. A total of 8370 asymptomatic women aged 50-69 years were screened with 2-view mammography, of which only 70 (0.84 percent) were selected for surgery after a thorough work-up. Cancers were verified histologically in 61 women and 9 showed non-malignant histology, giving a cancer detection rate of 7.3 cancers per thousand screened asymptomatic women. The benign/malignant ratio in the operated cases is thus approximately 1:7. The cancers detected showed all existing types of mammographic features where 77 percent (47 cases) showed rather typical findings, such as spiculated densities both with and without microcalcifications. The results indicate that surgery can be minimized without impairing the breast cancer detection rate. Radiologists in screening programs should be aware that a large proportion of non-palpable breast cancers present in rather unconventional forms. This point is important in order to maintain a high cancer detection rate and thereby justify the widespread use of mammography as a screening tool for breast cancer in asymptomatic women.

    2005-06-01

    Full Text Available Abstract Background The availability of geographic information from cancer and birth defect registries has increased public demands for investigation of perceived disease clusters. Many neighborhood-level cluster investigations are methodologically problematic, while maps made from registry data often ignore latency and many known risk factors. Population-based case-control and cohort studies provide a stronger foundation for spatial epidemiology because potential confounders and disease latency can be addressed. Methods We investigated the association between residence and colorectal, lung, and breast cancer on upper Cape Cod, Massachusetts (USA using extensive data on covariates and residential history from two case-control studies for 1983–1993. We generated maps using generalized additive models, smoothing on longitude and latitude while adjusting for covariates. The resulting continuous surface estimates disease rates relative to the whole study area. We used permutation tests to examine the overall importance of location in the model and identify areas of increased and decreased risk. Results Maps of colorectal cancer were relatively flat. Assuming 15 years of latency, lung cancer was significantly elevated just northeast of the Massachusetts Military Reservation, although the result did not hold when we restricted to residences of longest duration. Earlier non-spatial epidemiology had found a weak association between lung cancer and proximity to gun and mortar positions on the reservation. Breast cancer hot spots tended to increase in magnitude as we increased latency and adjusted for covariates, indicating that confounders were partly hiding these areas. Significant breast cancer hot spots were located near known groundwater plumes and the Massachusetts Military Reservation. Discussion Spatial epidemiology of population-based case-control studies addresses many methodological criticisms of cluster studies and generates new exposure

  2. The thyroid, iodine and breast cancer

    International Nuclear Information System (INIS)

    A renewal of the search for a link between breast cancer and thyroid disease has once again demonstrated an increased prevalence of autoimmune thyroid disease in patients with breast cancer. This is the most recent of many studies showing an association between a variety of thyroid disorders and breast cancer. Such an association is not surprising as both diseases are female predominant with a similar postmenopausal peak incidence. The significance of the presence of thyroid autoantibodies, particularly thyroid peroxidase antibodies, in serum from patients with breast cancer is unknown, but it has been suggested that antibody positivity is associated with better prognosis. One area in which thyroid and breast functions overlap is in the uptake and utilization of dietary iodide. Experimental findings showing the ability of iodine or iodine-rich seaweed to inhibit breast tumour development is supported by the relatively low rate of breast cancer in Japanese women who consume a diet containing iodine-rich seaweed. However, there is as yet no direct evidence that iodine, iodinated compounds, or a combination of iodine and selenium is the antimammary carcinogenic element in the Japanese diet. It remains to be resolved whether the perceived breast cancer–thyroid disease relationship is thyroid or iodine related or, in the case of thyroid autoantibodies, is the consequence of an immune response to the carcinoma. Is this response breast specific and does it relate to iodine status? These and many other questions await resolution before a definitive role in the natural history of breast carcinoma can be assigned to the thyroid

  3. Change in HER-2/neu Status from Negative to Positive following Treatment in Breast Cancer: A Case Report

    Directory of Open Access Journals (Sweden)

    Lakshmi Sivarajan

    2011-01-01

    Full Text Available Introduction: Approximately 25–30% of breast cancers are assumed to be HER-2/neu positive. It is well known that HER-2/neu-positive cancers after treatment with trastuzumab can become HER-2/neu negative. Change in HER-2/neu status from negative to positive following treatment has not been well studied. We describe a patient with inflammatory breast cancer who was initially HER-2/neu negative but became positive after treatment. A 59-year-old postmenopausal white female saw her surgeon for violaceous discoloration of the left breast for 4 months. The surgeon palpated a mass measuring 6 cm in the patient’s left breast. Additionally, there was violaceous discoloration involving two thirds of the breast. Biopsy of the breast mass and skin revealed inflammatory breast cancer. The tumor was estrogen receptor positive, progesterone receptor positive and HER-2/neu negative. The patient was given four cycles of chemotherapy with cyclophosphamide, doxorubicin and docetaxol. She subsequently underwent a mastectomy, excision of the skin over the chest wall and axillary node dissection. Of the axillary lymph nodes, 14/14 were involved. The tumor was still estrogen receptor positive and progesterone receptor positive, but HER-2/neu was 2+ by immunohistochemistry and amplified at 3.3 as detected by fluorescent in situhybridization. The patient received trastuzumab along with chemotherapy followed by radiation therapy and letrozole. She is currently receiving trastuzumab and letrozole in the adjuvant setting and appears to be doing well. Conclusion: A breast cancer which was initially HER-2/neu negative can become positive following treatment. Therefore, re-biopsy may be necessary during the course of treatment of breast cancer to re-assess the HER-2/neu status. This gives the clinician the opportunity to include drugs like trastuzumab and lapatinib in the treatment of patients with a transformation to HER-2/neu-positive cancer.

    Full Text Available Background. The incidence of premenopausal breast cancer is rising throughout South Asia. Our objective was to determine the role of risk factors associated with Westernization for premenopausal breast cancer in Bangladesh. Methods. We conducted a matched case-control study between January 1, 2007, and December 31, 2010, at four hospitals in Bangladesh. Cases were premenopausal women diagnosed with invasive breast cancer. Controls were premenopausal women with no personal history of breast cancer. Logistic regression was used to calculate the odds ratios (OR for breast cancer. Results. We identified 129 age-matched pairs. The mean age of breast cancer diagnosis was 37.5 years. Each year decrease in the age of menarche significantly increased the risk of breast cancer (OR = 1.67, 95% CI 1.09–2.56, P=0.02. The risk was also increased with a current body mass index of ≥25 kg/m2 (OR = 5.24, 95% CI 1.10–24.9, P=0.04. Age at first childbirth, parity, and breastfeeding were not significantly associated with premenopausal breast cancer risk (P>0.05. Conclusions. Age at menarche and adult weight gain were associated with premenopausal breast cancer risk. Other factors associated with Westernization may not be relevant to premenopausal breast cancer risk in Bangladesh.

  6. Aluminium, antiperspirants and breast cancer.

    2005-09-01

    Aluminium salts are used as the active antiperspirant agent in underarm cosmetics, but the effects of widespread, long term and increasing use remain unknown, especially in relation to the breast, which is a local area of application. Clinical studies showing a disproportionately high incidence of breast cancer in the upper outer quadrant of the breast together with reports of genomic instability in outer quadrants of the breast provide supporting evidence for a role for locally applied cosmetic chemicals in the development of breast cancer. Aluminium is known to have a genotoxic profile, capable of causing both DNA alterations and epigenetic effects, and this would be consistent with a potential role in breast cancer if such effects occurred in breast cells. Oestrogen is a well established influence in breast cancer and its action, dependent on intracellular receptors which function as ligand-activated zinc finger transcription factors, suggests one possible point of interference from aluminium. Results reported here demonstrate that aluminium in the form of aluminium chloride or aluminium chlorhydrate can interfere with the function of oestrogen receptors of MCF7 human breast cancer cells both in terms of ligand binding and in terms of oestrogen-regulated reporter gene expression. This adds aluminium to the increasing list of metals capable of interfering with oestrogen action and termed metalloestrogens. Further studies are now needed to identify the molecular basis of this action, the longer term effects of aluminium exposure and whether aluminium can cause aberrations to other signalling pathways in breast cells. Given the wide exposure of the human population to antiperspirants, it will be important to establish dermal absorption in the local area of the breast and whether long term low level absorption could play a role in the increasing incidence of breast cancer.

    Full Text Available Both diet and nutrition have been studied in relationship with breast cancer risk, as the great variation among different countries in breast cancer incidence could possibly be explained through the inflammatory and immune response, as well as antioxidant intake, among others.To date, no clear association with diet beyond overweight and weight gain has been found, except for alcohol consumption. Nonetheless, the small number of studies done in middle to low income countries where variability of food intake is wider,is beginning to show interesting results.Tanto la dieta como la nutrición han sido estudiadas en relación con el riesgo de cáncer de mama, dada la gran variación de incidencia de cáncer entre países, y la posibilidad de explicarla a través de la respuesta inflamatoria o inmune, así como ingesta de antioxidantes,entre otros.Hasta la fecha, ninguna asociación clara con la dieta ha sido encontrada, excepto para el consumo de alcohol, más allá del sobrepeso y del incremento de peso.

  12. Epigenetics and Breast Cancers

    Directory of Open Access Journals (Sweden)

    An T. Vo

    2012-01-01

    Full Text Available Several of the active compounds in foods, poisons, drugs, and industrial chemicals may, by epigenetic mechanisms, increase or decrease the risk of breast cancers. Enzymes that are involved in DNA methylation and histone modifications have been shown to be altered in several types of breast and other cancers resulting in abnormal patterns of methylation and/or acetylation. Hypermethylation at the CpG islands found in estrogen response element (ERE promoters occurs in conjunction with ligand-bonded alpha subunit estrogen receptor (Erα dimers wherein the ligand ERα dimer complex acts as a transcription factor and binds to the ERE promoter. Ligands could be 17-β-estradiol (E2, phytoestrogens, heterocyclic amines, and many other identified food additives and heavy metals. The dimer recruits DNA methyltransferases which catalyze the transfer of methyl groups from S-adenosyl-L-methionine (SAM to 5′-cytosine on CpG islands. Other enzymes are recruited to the region by ligand-ERα dimers which activate DNA demethylases to act simultaneously to increase gene expression of protooncogenes and growth-promoting genes. Ligand-ERα dimers also recruit histone acetyltransferase to the ERE promoter region. Histone demethylases such as JMJD2B and histone methyltransferases are enzymes which demethylate lysine residues on histones H3 and/or H4. This makes the chromatin accessible for transcription factors and enzymes.

    2012-01-01

    Full Text Available Patients with triple receptor-negative breast cancer often develop aggressive metastatic disease, which also might involve the brain. In many cases, systemic and local treatment is needed. It is important to consider the toxicity of chemo- and radiotherapy, especially when newly approved drugs become available. Randomised studies leading to drug approval often exclude patients with newly diagnosed brain metastases. Here we report our initial experience with eribulin mesylate and whole-brain radiotherapy (WBRT in a heavily pretreated patient with multiple brain, lung, and bone metastases from triple receptor-negative breast cancer. Eribulin mesylate was given after 4 previous lines for metastatic disease. Two weeks after the initial dose, that is, during the first cycle, the patient was diagnosed with 5 brain metastases with a maximum size of approximately 4.5 cm. She continued chemotherapy and received concomitant WBRT with 10 fractions of 3 Gy. After 3 cycles of eribulin mesylate, treatment was discontinued because of newly diagnosed liver metastases and progression in the lungs. No unexpected acute toxicity was observed. The only relevant adverse reactions were haematological events after the third cycle (haemoglobin 9.5 g/dL, leukocytes 3.1×109/L. The patient died from respiratory failure 18.5 months from diagnosis of metastatic disease, and 2.7 months from diagnosis of brain metastases. To the best of our knowledge, this is the first report on combined WBRT and eribulin mesylate.

Unlike the few previously reported cases of intrasinusoidal spread of breast cancer, our patient was palliated with a transjugular intrahepatic portosystemic shunt along with salvage chemohormonal therapy. In addition, our patient demonstrated proof of the principle of the dependence of capecitabine (Xeloda efficacy on dose scheduling as predicted by laboratory studies based on Gompertzian tumor growth and the Norton-Simon hypothesis. Case presentation We report the case of a 52-year-old Caucasian woman who developed radiological signs of portal hypertension without radiological evidence of hepatic metastasis five years after being diagnosed with metastatic breast cancer. She was receiving chemotherapy for stage IV breast cancer initially thought to be metastatic only to the bones. During salvage therapy with high-dose estradiol (Estradiol valerate, vinorelbine (Navelbine and bevacizumab (Avastin, she suddenly developed signs of portal hypertension confirmed on computed tomography and by portal and systemic venous pressure measurements. Drug toxicity due to bevacizumab (Avastin was initially and incorrectly entertained as a cause. The patient underwent palliative transjugular intrahepatic portosystemic shunt and transhepatic venous liver biopsy, which revealed the presence of rapidly progressive and uncontrolled metastatic breast cancer. The new discovery of radiologically occult intrasinusodal hepatic metastases with secondary micronodular cirrhosis was found to be the cause of her sudden onset portal hypertension. The patient's resistance to capecitabine (Xeloda was reversed by changing the schedule of medication to biweekly 7/7 (7 days ingesting drug alternating with 7 days off drug from

    Recent population studies suggest a role of smoking in the etiology of breast cancer, but few have been conducted among African American women. In a collaborative project of four large studies, we examined associations between smoking measures and breast cancer risk by menopause and hormone receptor status [estrogen receptor-positive (ER+), ER-negative (ER-) and triple-negative (ER-, PR-, HER2-)]. The study included 5791 African American women with breast cancer and 17376 African American controls. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated in multivariable logistic regression analysis with adjustment for study and risk factors. Results differed by menopausal status. Among postmenopausal women, positive associations were observed for long duration and greater pack-years of smoking: relative to never smoking, fully adjusted ORs were 1.14 (95% CI: 1.03-1.26) for duration ≥20 years and 1.16 (95% CI: 1.01-1.33) for ≥20 pack-years. By contrast, inverse associations were observed among premenopausal women, with ORs of 0.80 (95% CI: 0.68-95) for current smoking and 0.81 (95% CI: 0.69-0.96) for former smoking, without trends by duration. Associations among postmenopausal women were somewhat stronger for ER+ breast cancer. The findings suggest that the relation of cigarette smoking to breast cancer risk in African American women may vary by menopausal status and breast cancer subtype. PMID:27207658

    Full Text Available Murtaza Akhtar, Subhrajit Dasgupta, Murtuza Rangwala Department of Surgery, NKP Salve Institute of Medical Sciences and Research Centre, Nagpur, Maharashtra, India Introduction: Breast cancer is the most common female cancer in the world. Triple negative breast cancer (TNBC is a recently identified biological variant with aggressive tumor behavior and poor prognosis. Data of hormonal status from the Indian population is scarce due to financial constraints in performing immunohistochemistry evaluation. The present study aims to prospectively analyze receptor status of all breast cancer patients and identify TNBC and compare their clinical profile and short term survival with other non-TNBC group. Materials and methods: All cytologically and histopathologically confirmed cases of carcinoma breast were prospectively enrolled. In a longitudinal study at tertiary care hospital in central India based on the hormonal status, they were further divided into TNBC and other groups. Comparison of risk factors, clinical profile and short-term survival was carried out. Results: A total 85 patients were enrolled and of them 37 (43.7% were TNBC. On comparing risk factors ie, age, age at menarche, total reproductive age, age at first child birth, and menopausal status – no statistical significance was observed between the TNBC and non-TNBC groups. But on comparison of clinical profile TNBC tumors were significantly large with majority of patients presenting as locally advanced breast cancer (83%. No statistical difference was observed in axillary lymph node status between two groups. TNBC tumors were histologically more aggressive (grade 3 compared to other groups. No statistically significant difference was observed in short term overall survival but all three deaths were observed in the TNBC group only and two local recurrences after surgery were observed in the TNBC group. Conclusion: TNBC forms a large proportion of carcinoma breast patients in a central

    Full Text Available BACKGROUND: There is extensive epidemiological evidence that menopausal hormone therapy (MHT increases breast cancer risk, particularly combinations of estrogen and progestagen (EP. We investigated the effects of the specific formulations and types of therapies used by French women. Progestagen constituents, regimen (continuous or sequential treatment by the progestagen, and time interval between onset of menopause and start of MHT were examined. METHODS: We conducted a population-based case-control study in France in 1555 menopausal women (739 cases and 816 controls. Detailed information on MHT use was obtained during in-person interviews. Odds ratios and 95% confidence interval adjusted for breast cancer risk factors were calculated. RESULTS: We found that breast cancer risk differed by type of progestagen among current users of EP therapies. No increased risk was apparent among EP therapy users treated with natural micronized progesterone. Among users of EP therapy containing a synthetic progestin, the odds ratio was 1.57 (0.99-2.49 for progesterone-derived and 3.35 (1.07-10.4 for testosterone-derived progestagen. Women with continuous regimen were at greater risk than women treated sequentially, but regimen and type of progestagen could not be investigated independently, as almost all EP combinations containing a testosterone-derivative were administered continuously and vice-versa. Tibolone was also associated with an increased risk of breast cancer. Early users of MHT after onset of menopause were at greater risk than users who delayed treatment. CONCLUSION: This study confirms differential effects on breast cancer risk of progestagens and regimens specifically used in France. Formulation of EP therapies containing natural progesterone, frequently prescribed in France, was not associated with increased risk of breast cancer but may poorly protect against endometrial cancer.

  19. MTHFR 677C>T polymorphism and the risk of breast cancer: evidence from an original study and pooled data for 28031 cases and 31880 controls.

    Full Text Available Methylenetetrahydrofolate reductase (MTHFR acts at an important metabolic point in the regulation of cellular methylation reaction. It assists in the conversion of 5, 10-methylenetetrahydrofolate to 5-methyltetrahydrofolate. The latter aids in remethylation of homocysteine to de novo methionine that is required for DNA synthesis. The objective of this study was to examine the effect of MTHFR 677 C>T polymorphism on the risk of breast cancer in the Indian sub-continent.We genotyped 677 C>T locus in 1096 individuals that were classified into cases (N=588 and controls (N=508. Genotype data were analyzed using chi-square test. No significant difference was observed in the distribution of genotypes between cases and controls in north Indian (P = 0.932, south Indian (P = 0.865, and pooled data (P = 0.680. To develop a consensus regarding the impact of 677C>T polymorphism on breast cancer risk, we also conducted a meta-analysis on 28031 cases and 31880 controls that were pooled from sixty one studies. The overall summary estimate upon meta-analysis suggested no significant correlation between the 677C>T substitution and breast cancer in the dominant model (Fixed effect model: OR = 0.97, P=0.072, Random effects model: OR = 0.96, P = 0.084 or the recessive model (Fixed effect model: OR = 1.05, P = 0.089; Random effects model: OR= 1.08, P= 0.067.677 C>T substitution does not affect breast cancer risk in the Indo-European and Dravidian populations of India. Analysis on pooled data further ruled out association between the 677 C>T polymorphism and breast cancer. Therefore, 677 C>T substitution does not appear to influence the risk of breast cancer.

    The Korean Breast Cancer Society (KBCS) has reported a nationwide breast cancer data since 1996. We present a comprehensive report on the facts and trends of breast cancer in Korea in 2013. Data on the newly diagnosed patients in the year 2013 were collected from 99 hospitals by using nationwide questionnaire survey. Clinical characteristics such as stage of cancer, histologic types, biological markers, and surgical management were obtained from the online registry database. A total of 19,316 patients were newly diagnosed with breast cancer in 2013. The crude incidence rate of female breast cancer including carcinoma in situ was 76.2 cases per 100,000 women. The median age at diagnosis was 50 years, and the proportions of postmenopausal women with breast cancer accounted for more than half of total patients. The proportion of early breast cancer increased consistently, and the pathologic features have changed accordingly. Breast-conserving surgery was performed in more cases than total mastectomy in the year. The total number of breast reconstruction surgeries markedly increased approaching 3-fold in last 11 years. According to annual percentile change of invasive cancer incidence, the incidence increased rapidly until 2010. And thereafter the increase of it became steadier. For ductal carcinoma in situ, the incidence consistently increased during the same period without any joinpoint. Analysis of nationwide registry data will contribute to defining of the trends and characteristics of breast cancer in Korea.

    An association of cigarette smoking with breast cancer risk has been hypothesized. However, results from previous studies have been inconsistent. This case-control study investigated the association of cigarette smoking with breast cancer risk in terms of estrogen-receptor/progesterone-receptor (ER/PgR) status. From among female patients aged 30 years and over admitted to a single hospital in Japan between 1997 and 2011, 1,263 breast cancer cases (672 ER+/PgR+, 158 ER+/PgR-, 22 ER-/PgR+, 308 ER-/PgR- and 103 missing) and 3,160 controls were selected. History of smoking (ever, never), some smoking-related measures, and passive smoking from husbands (ever, never) were assessed using a self-administered questionnaire. Polytomous logistic regression and tests for heterogeneity across ER+/PgR + and ER-/PgR- were conducted. For any hormone receptor subtype, no significant association was observed between history of smoking (ever, never) and breast cancer risk. Analysis of smoking-related measures revealed that starting to smoke at an early age of ≤19 years was significantly associated with an increased risk of postmenopausal ER-/PgR- cancer (odds ratio = 7.01, 95% confidence interval: 2.07-23.73). Other measures of smoking such as the number of cigarettes per day, the duration of smoking, and start of smoking before the first birth were not associated with breast cancer risk for any receptor subtype. There was no association between passive smoking (ever, never) and breast cancer risk for any of the four subtypes. These results indicate that history of smoking and passive smoking from husbands may have no overall effect on breast cancer risk for any hormone receptor subtype. However, it is possible that women who start to smoke as teenagers may have a higher risk of developing postmenopausal ER-/PgR- cancer. Further studies are needed to clarify the association of smoking with breast cancer risk, especially the role of starting to smoke at an early age. PMID

In the study reported here, a 78-year-old female patient was admitted to the hospital with circulatory failure. At autopsy, the spleen (weight: 420 g) was extremely firm with a diffusely blackberry-colored cut surface. There were no signs of carcinomatous process at autopsy. By histology, the spleen showed diffuse metastatic carcinomatous infiltration. Using immunohistochemistry, an antibody to breast carcinoma antigen (BioGenex) labelled metastatic cells of the spleen and bone marrow. The patient was blood group O. Labelling for binding of lectins with and without blood group antigen specificity and monoclonal antibodies was carried out. The B blood group specific Banderiaea simplicifolia agglutinin I and an anti-B blood group monoclonal antibody labelled all the metastatic cells of spleen and bone marrow intensely. There was no detection of blood group A antigen by either binding of Dolichos biflorus agglutinin or anti-blood group A monoclonal antibodies. These observations raise the possibility that the detected incompatible B blood group antigen determinants on the metastatic cells were immunogenic. The surviving carcinoma cells may have found a place of refuge from immune surveillance in the spleen and in the bone marrow

    Full Text Available Background: Breast cancer is now the most common cancer in many parts of India and the incidence varies from 12 to 31/100000, and is rising. Locally advanced breast cancer (LABC accounts for 30 - 35% of all cases of breast cancers in India. LABC continues to present a challenge and imposes a major health impact in our country. Materials and Methods: We carried out a analysis of our LABC patients who received neoadjuvant chemotherapy (NACT at our hospital over a 10-year period, from January 1995 to December 2004. We analyzed the response to NACT, disease-free survival (DFS, and overall survival (OS. Results: Patients with stages IIIA, IIIB, and IIIC were included. LABC comprised of 26.24% (609 patients of new patients. One hundred and twenty-eight (31.1% patients received NACT. Median age was 48 years and estrogen receptor was positive in 64%. Chemotherapy protocol was an FEC (5-Fluorouracil, Epirubicin, Cyclophosphamide regimen in the following doses: Cyclophosphamide 600 mg/m2, 5-FU 600 mg/m2, and Epirubicin 75 mg/m2 given every three weeks, six doses, followed by modified radical mastectomy (MRM and locoregional radiotherapy. The overall response rate (complete response (CR + partial response (PR was 84.4%, clinical CR (cCR was 13.3% and pathological CR (pCR was 7.8%. Median DFS and OS were 33 and 101 months, respectively. The disease-free survival (DFS and overall survival (OS at five years were 41 and 58%, respectively. Conclusions: This study analyzes the outcome in patients who received NACT, in the largest number of LABC patients from a single center in India, and our results are comparable to the results reported from other centers.

    This case series describes 3 cases in which ultrasound-guided intercostobrachial perineural injection was used for intercostobrachial neuralgia, a common cause of postmastectomy pain syndrome. All cases had undergone modified radical mastectomy with axillary lymph node dissection for breast cancer. Two cases developed axillary and unilateral chest wall pain. The third case initially presented with axillary pain and lateral shoulder pain 1 year out from radical mastectomy. After a cervical epidural steroid injection, her lateral shoulder pain resolved, but she continued to have residual chest wall paresthesia. It was at this time, we decided to treat with an intercostobrachial nerve perineural injection. Injury to the intercostobrachial nerve is thought to be a common cause of postmastectomy pain. In our case series, all patients had pain relief after the intercostobrachial perineural injection. There is a relative dearth of published information on the treatment of postmastectomy pain and more specifically intercostobrachial neuralgia. We review the anatomy of the intercostobrachial nerve and its variants, etiologies of intercostobrachial neuralgia, and current indications and methods of an intercostobrachial perineural injection.

  16. Case-control analysis of breast cancer in a screened population: implications for the assessment of environmental exposure risk factors

    International Nuclear Information System (INIS)

    The appropriateness of using epidemiologic data from screened populations is investigated. Particular emphasis is given to design advantages and disadvantages of case-control studies using such data, statistical issues that arise in their analysis, and implications for testing hypotheses concerning environmental exposures. Concepts and techniques are illustrated with a recently completed study of breast cancer among screenees. Adjustment of odds ratios for number of screenings, symptomticity and year of first screening was necessary to avoid bias. When case subgroups are compared by classical methods, it should be done directly, rather than indirectly to controls, otherwise spurious trends may appear that are the result of the choice of baseline exposure group rather than risk differences. The multiple logistic model was used to adjust for many factors simultaneously and to model interaction between study factors. It is shown how careful interpretation of logistic regression parameters enables one to design a unified test to compare case subgroups simultaneously to one another and to controls and to test for initiation and promotion of cancer by environmental risk factors

    2010-02-01

    Male breast cancer (MaleBC) is a rare disease, accounting for development; low-penetrance gene mutations (i.e. CHEK-2) are more common but involve a lower risk increase. About 90% of all male breast tumors have proved to be invasive ductal carcinomas, expressing high levels of hormone receptors with evident therapeutic returns. The most common clinical sign of BC onset in men is a painless palpable retroareolar lump, which should be evaluated by means of mammography, ultrasonography and core biopsy or fine needle aspiration (FNA). To date, there are no published data from prospective randomized trials supporting a specific therapeutic approach in MaleBC. Tumor size together with the number of axillary nodes involved are the main prognostic factors and should guide the treatment choice. Locoregional approaches include surgery and radiotherapy (RT), depending upon the initial clinical presentation. When systemic treatment (adjuvant, neoadjuvant and metastatic) is delivered, the choice between hormonal and or chemotherapy (CT) should depend upon the clinical and biological features, according to the FBC management guidelines. However great caution is required because of high rates of age-related comorbidities. PMID:19427229

    Objective To explore the clinical and pathological characteristics of 110 interval cancer cases in first three rounds breast cancer screening of Shunyi District. Methods The breast cancer incidence registration system and the database of breast cancer screening were linked to identify the interval cancer cases. The characteristics of interval breast cancers were compared with breast cancers from the outpatients among the same period. Results Compared with breast cancer outpatients, interval cancer cases were younger and of smaller size on breast ultrasonography( P<0�05) . Compared with similar size of breast cancer outpatients, true in⁃terval cancer cases had significantly higher proportions of malignant calcification on mammography and invasive ductal carcinoma( P<0�05) . Among the total 110 interval breast cancer cases, only 1 case was assigned to mammography as a referral, and the referral pro⁃portion was only 0�91%. In regard to the diagnosis mammography, 53 out of 103 interval cases( 48�2%) were characterized by malig⁃nant calcification. Conclusion In breast cancer screening, women with younger age are prone to interval cancer. As nearly half of the interval cancer cases contained malignant calcification on diagnostic mammography, breast cancer screening using breast ultrasonography and additional mammography may avoid part of interval cancer cases.%目的:分析顺义区三轮乳腺癌筛查中110例间期癌患者的临床及病理特征。方法将顺义区历年乳腺癌发病个案信息与北京市妇幼保健网络信息系统中适龄女性乳腺癌筛查数据进行关联,查询乳腺间期癌患者。将间期癌患者与同时期在我院乳腺中心就诊的乳腺癌患者进行特征比较。结果与门诊收治的原发性乳腺癌相比,间期癌患者年龄偏小、超声肿物较小,差异均有统计学意义( P<0�05)。与病灶大小相近的门诊收治的乳腺癌患者相比,真正间期癌X线检查恶

    Full Text Available Summary. Breast cancer is by far the most common cancer in women in the western world. In 90% of breast cancers, environmental factors are among the causes. The frequency with which the tumour occurs in the outer upper part of the breast has risen with above average rates in recent decades. Aluminium salts as ingredients in deodorants and antiperspirants are being absorbed by the body to a greater extent than hitherto assumed. Their toxicity for healthy and diseased breast tissue cells includes various well-documented pathomechanisms. In the sense of primary and secondary prevention, the cancer-triggering potential of aluminium and its use in anti-perspirant deodorants must be re-evaluated. For the same reason the access to a targeted diagnosis and treatment of aluminium loading must be facilitated.

    Full Text Available With the aim of evaluating clinical aspects, age, breed, presence of metastasis, chemotherapeutical protocol, use of COX-2 inhibitors and survival rate in female dogs diagnosed with inflammatory carcinoma at the Hospital Veterinario de Uberaba (HVU, a retrospective analysis was performed on the medical records of 14 female dogs seen at HVU between July, 2011 and July, 2012 and diagnosed with inflammatory breast cancer. The breeds included were crossbred, poodle, Brazilian terrier, teckel and Belgian shepherd. Average age: 11.1 years. Outbreaks of distant metastasis were detected in 7 animals, out of which 5 patients received COX-2 inhibitors as sole treatment and only 4 received chemotherapeutical treatment. The protocol, constituted by piroxicam, cyclophosphamide, carboplatin and doxorubicin showed the highest survival time (210 days. In conclusion, inflammatory carcinoma is a disease of bad prognosis, short survival time and produces systemic alterations that reduce therapeutic response. Apparently, the most accurate therapeutic form is the association of COX-2 inhibitors and chemotherapeutics; however, controlled clinical studies are needed in order to evaluate these suggestions.

    Objective:The pathological complete response (pCR) rates of neoadjuvant chemotherapy (NAC) in triple-nega-tive breast cancer (TNBC) was reported higher than that in non-TNBC but ranged from 12%to 48%. pCR was reported to be a predictor of long overal survival and exact pCR rate of NAC in TNBC would give us some hints on how to improve outcomes of TNBC patients. The meta-analysis was conducted to estimate the pCR rate of NAC for TNBC through contrasting the pCR rates of TNBC and non-TNBC tumors in NAC. Methods:Studies were selected from the PubMed database and Cochrane Col aboration Library. pCR rates were col ected in groups of TNBC and non-TNBC tumors. Review Manager 4.2 was used to perform forest plots and funnel plots. Results:The analysis included 22 studies with 7168 patients, the aggregate pCR rate was 29.5%in TNBC group, which was 17.7%higher than non-TNBC. The summary relative risk (RR) for pCR rate of TNBC group with that of non-TNBC group was 2.55. No obvious statistical heterogeneity and publication bias was detected. Conclu-sion:This meta-analysis demonstrated that NAC showed a higher pCR rate in TNBC than non-TNBC.

  6. Screening for breast cancer with mammography

    International Nuclear Information System (INIS)

    Mammography is generally accepted as a useful problem-solving clinical tool in characterizing known breast lesions, so that appropriate and timely treatment can be given. However, it remains grossly underutilized at what it does best: screening. The major strengths of mammography are (a) its ability to detect breast cancer at a smaller, potentially more curable stage than any other examination, and (b) its proved efficacy in reducing breast cancer mortality in asymptomatic women aged 40-74. If, as has recently been estimated, screening with mammography and physical examination can be expected to lower breast cancer deaths by 40%-50% among those actually examined (13), then the lives of almost 20,000 U.S. women might be saved each year if screening were to become very widely used. The challenges of the next decade are clear, to mount much more effective campaigns to educate physicians and lay women about the life-saving benefits of breast cancer screening, to devise increasingly effective and lower cost screening strategies, to further improve the current high quality of mammographic imaging despite its increasing proliferation, and to train large numbers of breast imaging specialists to guarantee that the growing case load of screening and problem-solving mammograms is interpreted with a very high level of skill

Breast cancer is especially known for long asymptomatic periods, up to 25 years, with no evidence of the disease, followed by a relapse. Factors that determine the cell's decision to enter a dormant state and that control its duration remain unclear. In recent years, considerable progress has been made in understanding how tumor cells circulating in the blood interact and extravasate into secondary sites and which factors might determine whether these cells survive, remain dormant, or become macrometastases. The mechanisms of tumor cell dormancy are still not clear. Two different hypotheses are currently discussed: tumor cells persist either by completely withdrawing from the cell cycle or by continuing to proliferate at a slow rate that is counterbalanced by cell death. Because dormant disseminated tumor cells may be the founders of metastasis, one hypothesis is that dormant tumor cells, or at least a fraction of them, share stem cell-like characteristics that may be responsible for their long half-lives and their suggested resistance to standard chemotherapy. Therefore, knowledge of the biology of tumor cell dormancy may be the basis from which to develop innovative targeted therapies to control or eliminate this tumor cell fraction. In this review, we discuss biological mechanisms and clinical implications of tumor dormancy in breast cancer patients.Keywords: tumor dormancy, disseminated tumor cell, circulating tumor cell, targeted therapy

    Inflammatory breast cancer (IBC) is both the least frequent and the most severe form of epithelial breast cancer. The diagnosis is based on clinical inflammatory signs and is reinforced by pathological findings. Significant progress has been made in the management of IBC in the past 20 years. Yet survival among IBC patients is still only one-half that among patients with non-IBC. Identification of the molecular determinants of IBC would probably lead to more specific treatments and to improve...

    Introduction Breast cancer is the most common cancer in morocco women were it occupies the first place in term of incidence and mortality. The aim of the present paper is to evaluate the risk factors associated with a breast cancer in a population of Moroccan women. Methods A case-control study was conducted with population women whose age is less than 40 years during 2008-2010 at the National Institute of Oncology of Rabat. These women were interviewed for Epidemiological information and risk factor for breast cancer. Results Included in this study were 124 cases and 148 age matched controls. No statistically significant case-control difference was found for the early age of menarche (OR = 2.474; CI 95%: 1.354- 4.521), and family antecedents of first degree of breast cancer (OR = 11.556; 95% CI: 2.548-52.411). However physical activity (OR = 0.507; 95% CI: 0.339 -0.757) early maternity age (OR = 0.212; 95% CI: 0.087 - 0.514), multiparity (OR = 0.742; 95% CI: 0.359 -1.539) and breastfeeding than 6 months (OR = 0.739; 95% CI: 0.357 -1.523) appear as significant protective factors. Conclusion This study show the criminalization of only part of the known risk factors of breast cancer in this age group and confirms the probable protective role of physical activity and factors related to life reproductive women in our study (early childbearing, multiparity and lactation).

  15. The Role of Large-Format Histopathology in Assessing Subgross Morphological Prognostic Parameters: A Single Institution Report of 1000 Consecutive Breast Cancer Cases

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available Breast cancer subgross morphological parameters (disease extent, lesion distribution, and tumor size provide significant prognostic information and guide therapeutic decisions. Modern multimodality radiological imaging can determine these parameters with increasing accuracy in most patients. Large-format histopathology preserves the spatial relationship of the tumor components and their relationship to the resection margins and has clear advantages over traditional routine pathology techniques. We report a series of 1000 consecutive breast cancer cases worked up with large-format histology with detailed radiological-pathological correlation. We confirmed that breast carcinomas often exhibit complex subgross morphology in both early and advanced stages. Half of the cases were extensive tumors and occupied a tissue space ≥40 mm in its largest dimension. Because both in situ and invasive tumor components may exhibit unifocal, multifocal, and diffuse lesion distribution, 17 different breast cancer growth patterns can be observed. Combining in situ and invasive tumor components, most cases fall into three aggregate growth patterns: unifocal (36%, multifocal (35%, and diffuse (28%. Large-format histology categories of tumor size and disease extent were concordant with radiological measurements in approximately 80% of the cases. Noncalcified, low-grade in situ foci, and invasive tumor foci <5 mm were the most frequent causes of discrepant findings.

  16. Environmental chemical exposures and breast cancer

    Directory of Open Access Journals (Sweden)

    E. Stanley

    2016-02-01

    Full Text Available As a hormone-sensitive condition with no single identifiable cause, breast cancer is a major health problem. It is characterized by a wide range of contributing factors and exposures occurring in different combinations and strengths across a lifetime that may be amplified during periods of enhanced developmental susceptibility and impacted by reproductive patterns and behaviours. The vast majority of cases are oestrogen-receptor positive and occur in women with no family history of the disease suggesting that modifiable risk factors are involved. A substantial body of evidence now links oestrogen-positive breast cancer with environmental exposures. Synthetic chemicals capable of oestrogen mimicry are characteristic of industrial development and have been individually and extensively assessed as risk factors for oestrogen-sensitive cancers. Existing breast cancer risk assessment tools do not take such factors into account. In the absence of consensus on causation and in order to better understand the problem of escalating incidence globally, an expanded, integrated approach broadening the inquiry into individual susceptibility breast cancer is proposed. Applying systems thinking to existing data on oestrogen-modulating environmental exposures and other oestrogenic factors characteristic of Westernisation and their interactions in the exposure, encompassing social, behavioural, environmental, hormonal and genetic factors, can assist in understanding cancer risks and the pursuit of prevention strategies. A new conceptual framework based on a broader understanding of the “system” that underlies the development of breast cancer over a period of many years, incorporating the factors known to contribute to breast cancer risk, could provide a new platform from which government and regulators can promulgate enhanced and more effective prevention strategies.

  1. On ionising radiation and breast cancer risk

    International Nuclear Information System (INIS)

    A cohort of 3,090 women with clinical diagnosis of benign breast disease (BBD) was studied. Of these, 1,216 were treated with radiation therapy during 1925-54 (median age 40 years). The mean dose to the breasts was 5.8 Gy (range 0-50 Gy). Among other organs the lung received the highest scattered dose (0.75 Gy; range 0.004-8.98 Gy) and the rectum the lowest (0.008 Gy; range 0-0.06 Gy). A pooled analysis of eight breast cancer incidence cohorts was done, including: tumour registry data on breast cancer incidence among women in the Life Span Study cohort of atomic bomb survivors; women in Massachusetts who received repeated chest fluoroscopic during lung collapse treatment for tuberculosis; women who received x-ray therapy for acute post-partum mastitis; women who were irradiated in infancy for enlarged thymus glands ; two Swedish cohorts of women who received radiation treatments during infancy for skin hemangioma; and the BBD) cohort. Together the cohorts included almost 78,000 women (-35,000 were exposed), around 1.8 million woman-years and 1500 cases. The breast cancer incidence rate as a function of breast dose was analysed using linear-quadratic Poisson regression models. Cell-killing effects and other modifying effects were incorporated through additional log-linear terms. Additive (EAR) and multiplicative (ERR) models were compared in estimating the age-at-exposure patterns and time related excess. The carcinogenic risks associated with radiation in mammographic mass screening is evaluated. Assessment was made in terms of breast cancer mortality and years of life. Effects were related to rates not influenced by a mammographic mass screening program and based on a hypothetical cohort of 100,000 40-year old women with no history of breast cancer being followed to 100 years of age. Two radiation risk assumptions were compared. The dose-response relationship is linear with little support in data for an upward curvature at low to medium doses. The competing effect

    Aim: The aim of the study is to investigate the impact of the cytochrome P450 2E1, which is the most efifcient CYP450 family member in generating reactive oxygen species (ROS), on cellular energy metabolism of breast cancer cells and therefore the effects of CYP2E1 on breast carcinogenesis.Methods: The estrogen receptor positive MCF-7 and the triple negative MDA-MB-231 breast cancer cells were used as experimental system to estimate ROS generation in these cells overexpressing CYP2E1 and treated with the glycolytic inhibitors 3-bromopyruvate or 2-deoxyglucose in the presence or absence of the CYP2E1 inhibitor chlormethiazole. Adenosine triphosphate (ATP) assay was used to measure ATP production and lactate assay to quantify the eflfux of lactic acid in breast cancer cells treated with the CYP2E1 inhibitor chlormethiazole, the mitochondrial membrane potential and cell viability assays were employed to assess the pathway of cellular energy production and cellular death respectively after treatment of MCF-7 and MDA-MB-231 with the CYP2E1 activator acetaminophen or the CYP2E1 inhibitor chlormethiazole. Results: The results indicated increased ROS generation in breast cancer cells overexpressing CYP2E1. ROS generation was differentially regulated in breast cancer cells upon treatment with the CYP2E1 inhibitor chlormethiazole. Chlormethiazole treated MCF-7 cells exhibited reduced lactate eflfux implying that CYP2E1 directly or indirectly regulates the glycolytic rate in these cells. Furthermore the mitochondrial membrane potential of both MCF-7 and MDA-MB-231 cells was differentially affected by the CYP2E1 activator acetaminophen versus the CYP2E1 inhibitor chlormethiazole providing additional support for the involvement of CYP2E1 in energy metabolic pathways in breast cancer.Conclusion: Results presented in this study provide evidence to suggest that CYP2E1 regulates cellular energy metabolism of breast cancer cells in a manner dependent on cell type and potentially on

    One-third of women with self-discovered breast cancer are symptomatic for 3 months or more before seeking evaluation. Few studies examine women's accounts of this important time. Using narrative analysis in the style of Labov and Waletzky, breast cancer cases from a larger mixed-tumor sample of patients receiving chemotherapy were examined for the details of breast cancer symptom discovery and the events relevant to the timing of diagnosis and treatment. The majority (56.3%) of women in the sample sought evaluations within days, many proceeding to immediate diagnosis. Factors cited by women as influencing the delayed timing of initial provider evaluation were that they attributed the symptoms to a benign process, and they perceived gender role-related constraints. Many women in this younger-aged sample had false-negative mammographic examinations, and many reported receiving false reassurance from providers on initial consultation visits. Women who delayed evaluations sought them only as symptoms advanced.

  8. A fully-automated software pipeline for integrating breast density and parenchymal texture analysis for digital mammograms: parameter optimization in a case-control breast cancer risk assessment study

    2013-02-01

    Estimating a woman's risk of breast cancer is becoming increasingly important in clinical practice. Mammographic density, estimated as the percent of dense (PD) tissue area within the breast, has been shown to be a strong risk factor. Studies also support a relationship between mammographic texture and breast cancer risk. We have developed a fullyautomated software pipeline for computerized analysis of digital mammography parenchymal patterns by quantitatively measuring both breast density and texture properties. Our pipeline combines advanced computer algorithms of pattern recognition, computer vision, and machine learning and offers a standardized tool for breast cancer risk assessment studies. Different from many existing methods performing parenchymal texture analysis within specific breast subregions, our pipeline extracts texture descriptors for points on a spatial regular lattice and from a surrounding window of each lattice point, to characterize the local mammographic appearance throughout the whole breast. To demonstrate the utility of our pipeline, and optimize its parameters, we perform a case-control study by retrospectively analyzing a total of 472 digital mammography studies. Specifically, we investigate the window size, which is a lattice related parameter, and compare the performance of texture features to that of breast PD in classifying case-control status. Our results suggest that different window sizes may be optimal for raw (12.7mm2) versus vendor post-processed images (6.3mm2). We also show that the combination of PD and texture features outperforms PD alone. The improvement is significant (p=0.03) when raw images and window size of 12.7mm2 are used, having an ROC AUC of 0.66. The combination of PD and our texture features computed from post-processed images with a window size of 6.3 mm2 achieves an ROC AUC of 0.75.

    The most frequent cancer among women in the Western world arises in the breast accounting for over 1.7 million new cases in 2012, a number which is still rising. Much attention is paid to the discovery of new ways to prevent breast cancer, as is the search for new treatment modalities with a minimum

  12. Breast cancer correlates in a cohort of breast screening program participants in Riyadh, KSA

    International Nuclear Information System (INIS)

    Background: Breast cancer is the first cancer among females in the Kingdom of Saudi Arabia, accounting for 27.4% of all newly diagnosed female cancers in 2010. There are several risk factors affecting the incidence of breast cancer where some factors influence the risk more than the others. Aim: We aimed to identify the different risk factors related to breast cancer among females participating in the breast-screening program in Riyadh, KSA. Methods: Based on data from phase-I of the breast-screening program, a case-control study was conducted on women living in Riyadh, KSA. A sample of 349 women (58 cases and 290 controls) was recruited to examine the different breast cancer correlates. Multivariate regression model was built to investigate the most important risk factors. Results: The mean age of cases was 48.5 ± 7.1 years. Age at marriage, number of pregnancy, age at menopause, oral contraceptive pills, breast feeding and family history of breast cancer in first-degree relative were identified as the most important correlates among the studied cohort. Conclusions: The findings of the current work suggested that age at marriage, age at menopause ≥50 years, and 1st degree family history of breast cancer were risk factors for breast cancer, while, age at menopause<50 years, number of pregnancies and practicing breast feeding were protective factors against breast cancer. There was no effect of body mass index or physical inactivity. Further studies are needed to explore the hereditary, familial and genetic background risk factors in Saudi population.

    Various effective strategies have recently been described in the treatment of breast cancer, including endocrine therapy, chemotherapy, and molecular-targeted therapy, providing long-term survival benefits even after cancer recurrence. However, terminal-stage patients experience side effects and worse quality of life (QOL), in addition to deterioration of their general condition caused by the progression of the disease itself. When providing the best supportive care, use of anti-cancer drugs is not taboo and can represent a good option as long as physical, social, psychological, and spiritual supports are provided to both the patients and their families. Medroxyprogesterone acetate (MPA) is an endocrine therapeutic drug. In Japan, MPA is used only as a late-line endocrine therapy for breast cancer recurrence because many other endocrine therapy drugs are much more effective and MPA increases the risk of thrombosis and obesity. Here, we report 2 patients with breast cancer who reached terminal stage more than 10 years after the first diagnosis. MPA was administered as the final-line treatment. During that time, their appetite and QOL improved and the patients became more active than when they had been undergoing aggressive anticancer treatment. Both patients spent quality time with their families until their death. MPA may be a good option as part of palliative care of breast cancer patients in terminal stage. PMID:27067852

    Normofractionated radiotherapy is standard for adjuvant management of patients treated with breast conservative surgery for breast cancer. However, many elderly patients are not eligible to such strategy, either because of concurrent diseases, or because the tumor is inoperable. Several protocols of exclusive radiotherapy have been reported in the literature, frequently using hypofractionated radiotherapy and endocrine therapy. We report a case of a patient treated with exclusive endocrine and radiotherapy and address the state of the art on hypofractionated schemes for the management of elderly breast cancer patients. While hypofractionated radiotherapy does not compromise the oncologic or cosmetic outcome, there is no prospective data that assesses the place of radiotherapy for the exclusive treatment of elderly patients. This strategy should be further assessed in clinical randomized trial.

    This study aimed to examine the joint effects of folate intake, polymorphisms of 5,10- methylenetetrahydrofolate reductase (MTHFR), methionine synthesis reductase (MTRR) and methionine synthase (MTR) genes and breast cancer risk. A case-control study of 570 consecutively recruited breast cancer cases and 576 controls was conducted in Guangzhou, China. Multifactor dimensionality reduction and logistic regression approach were used to evaluate gene-gene interaction. The covariates were chosen based on comparison of baseline characteristics of cases and controls. Folate intake was found to be inversely associated with breast cancer risk. The MTRRrs162036 GG genotype was associated with a decreased risk of breast cancer [adjusted odds ratio (OR) 0.41, 95% confidence interval (CI) 0.20-0.85]. Compared with the wild-type group (MTRRrs162036 AA with MTRrs1805087 AA) MTRRrs162036 AA with MTRrs1805087 GA + GG was associated with a decreased risk (OR 0.70, 95% CI 0.48-1.03). With the combined MTHFRrs1801131 TT and MTHFRrs1801133 GG genotypes as a reference, MTHFRrs1801131 TT with MTHFRrs1801133 GA + AA was associated with a decreased risk (OR 0.78, 95% CI 0.57 - 1.08) and MTHFRrs1801131 GT + GG with MTHFRrs1801133 GA + AA was associated with an increased risk (OR 1.35, 95% CI 0.88-2.05). The joint impact of MTRRrs162036 and MTRrs1805087, MTHFRrs1801131 and MTHFRrs1801133, folate and MTHFRrs1801133 may contribute to breast cancer risk.

    Estrogens, and to a lesser extent progesterones, influence the proliferation, differentiation and physiology of breast tissue as well as the development and progression of breast cancer. Genetic variants in the steroid hormone receptor genes ESR1 and PGR (belonging to the nuclear receptor superfamily) could therefore modify sporadic breast cancer susceptibility. Two studies have shown a protective effect associated with variants in ESR1 in 2 distinct populations. We studied 4 single nucleotide polymorphisms (SNPs) in ESR1 and 4 in PGR in 550 consecutive and unrelated sporadic Spanish breast cancer patients and 564 healthy Spanish controls. We observed a dominant protective effect for the S10S variant in ESR1, with an estimated odds ratio (OR) of 0.75 (95% CI = 0.58-0.97; p = 0.03) although functional studies did not show changes in the RNA stability. A small subset of individuals carried a haplotype combination that corroborates this protection. No other SNP considered in either gene was found to be associated with sporadic breast cancer. Our results obtained in a European population confirm the protective role of the S10S variant in ESR1, previously reported in an Asian and a European-American population. PMID:16477637

    Recently, we reported microchimerism to be oppositely associated with maternal breast and colon cancer. In women with a blood test positive for male microchimerism the risk of breast cancer development was reduced to one third, whereas the risk of colon cancer was elevated 4-fold. In this article addendum, I report the survival of cases in the original study after being diagnosed with cancer. Despite small numbers, the analysis suggests that microchimerism may be positively associated with su...
