    Full Text Available Background: Caregivers of individuals suffering from cancer illnesses are at risk of having subjected to mental health consequences. There is a paucity of data comparing the caregiver burden of cancer breast and cancer cervix patients. Aim: The aim of the present study is to compare the caregiver burden of cancer breast and cancer cervix patients. To study the association of caregiver burden with demographic factors like age, gender, duration of caregiving etc. Materials & Methods: This Cross sectional study is performed on the key relatives of patients of 31 cancer cervix and 31 cancer breast patients. Burden assessment schedule was used. Results: Our findings suggest burden is more in male caregivers of breast cancer patients. It is not so in caregivers of cancer cervix patients. Whenever the caregiver is closely related to the patients the burden is high in both groups. Whenever the burden scores were high the depression scores were also high. Treatment modalities as a whole correlates with burden scores in caregivers of breast cancer patients but not in cancer cervix patients. Conclusion: Caregivers with breast and cervical cancer patients are vulnerable if the caregiver is male, from low socioeconomical background, more closely related and when the patients received poor treatment modalities.

  6. Eighteen cases of small breast cancer: a comparative study of mammography, CT scan and pathology

    International Nuclear Information System (INIS)

    Objective: To improve the early diagnosis of breast cancer through a study of the mammography and CT findings of small breast cancer. Methods: The mammography and CT findings of 18 cases of small breast cancer (φ≤2.0 cm in diameter) were studied and compared with pathological results. Results: The diagnostic accuracy of CT and mammography was 83% and 61%, respectively. There was a statistical difference between both modalities (P<0.05), CT scan was superior to mammography. However, there was no difference between them when assessing the lesion arising in F-type breast. In detecting breast fine cluster of calcification, the sensitivity of mammography was better than CT scan. Conclusion: The patient suspected of small breast cancer should take mammography as the first evaluation. CT scan is reserved for the further investigation. The mammography combined with CT scan can improve the early diagnostic rate of breast cancer

    Full Text Available Abstract Background An estimated 12% of females in the United States will develop breast cancer in their lifetime. Although, there are advances in treatment options including surgery and chemotherapy, breast cancer is still the second most lethal cancer in women. Thus, there is a clear need for better methods to predict prognosis for each breast cancer patient. With the advent of large genetic databases and the reduction in cost for the experiments, researchers are faced with choosing from a large pool of potential prognostic markers from numerous breast cancer gene expression profile studies. Methods Five microarray datasets related to breast cancer were examined using gene set analysis and the cancers were categorized into different subtypes using a scoring system based on genetic pathway activity. Results We have observed that significant genes in the individual studies show little reproducibility across the datasets. From our comparative analysis, using gene pathways with clinical variables is more reliable across studies and shows promise in assessing a patient's prognosis. Conclusions This study concludes that, in light of clinical variables, there are significant gene pathways in common across the datasets. Specifically, several pathways can further significantly stratify patients for survival. These candidate pathways should help to develop a panel of significant biomarkers for the prognosis of breast cancer patients in a clinical setting.

  15. Characterization of genomic alterations in radiation-associated breast cancer among childhood cancer survivors, using comparative genomic hybridization (CGH arrays.

    Full Text Available Ionizing radiation is an established risk factor for breast cancer. Epidemiologic studies of radiation-exposed cohorts have been primarily descriptive; molecular events responsible for the development of radiation-associated breast cancer have not been elucidated. In this study, we used array comparative genomic hybridization (array-CGH to characterize genome-wide copy number changes in breast tumors collected in the Childhood Cancer Survivor Study (CCSS. Array-CGH data were obtained from 32 cases who developed a second primary breast cancer following chest irradiation at early ages for the treatment of their first cancers, mostly Hodgkin lymphoma. The majority of these cases developed breast cancer before age 45 (91%, n = 29, had invasive ductal tumors (81%, n = 26, estrogen receptor (ER-positive staining (68%, n = 19 out of 28, and high proliferation as indicated by high Ki-67 staining (77%, n = 17 out of 22. Genomic regions with low-copy number gains and losses and high-level amplifications were similar to what has been reported in sporadic breast tumors, however, the frequency of amplifications of the 17q12 region containing human epidermal growth factor receptor 2 (HER2 was much higher among CCSS cases (38%, n = 12. Our findings suggest that second primary breast cancers in CCSS were enriched for an "amplifier" genomic subgroup with highly proliferative breast tumors. Future investigation in a larger irradiated cohort will be needed to confirm our findings.

    Full Text Available Abstract Background Germline mutations in the BRCA1 gene predispose to the development of breast cancer, exhibiting a specific histological phenotype. Identification of possible hallmarks of these tumors is important for selecting patients for genetic screening and provides inside in carcinogenetic pathways. Since BRCA1-associated breast cancers have pushing borders that prevent them from easily reaching vessels and are often of the medullary (like type that is known to have a low rate of lympho-vascular invasion (LVI, we hypothesized that absence of LVI could characterize BRCA1 related breast cancer. Methods A population of 68 BRCA1 related invasive breast cancers was evaluated for LVI by an experienced breast pathologist blinded to mutation status, and compared to a control group matched for age, grade and tumor type. Results LVI was present in 25.0% of BRCA1 related cases, compared to 20.6% of controls (P = 0.54, OR = 1.29, CI 0.58-2.78. Conclusion LVI is frequent in BRCA1 germline mutation related breast cancers, but seems to occur as often in sporadic controls matched for age, grade and tumor type. Apparently, these hereditary cancers find their way to the blood and lymph vessels despite their well demarcation and often medullary differentiation.

    More than 20-year follow-up of A-bomb survivors in Hiroshima and Nagasaki has a crucial role in determining the relationship of radiation to the occurrence of breast cancer. In 1967, Wanebo et al have first reported 27 cases of breast cancer during the period 1950-1966 among the Adult Health Study population of A-bomb survivors. Since then, follow-up surveys for breast cancer have been made using the Life Span Study (LSS) cohort, and the incidence of breast cancer has increased year by year; that is breast cancer was identified in 231 cases by the first LSS series (1950-1969), 360 cases by the second LSS series (1950-1974), 564 cases by the third LSS series (1950-1980), and 816 cases in the fourth LSS series (1950-1085). The third LSS series have revealed a high risk for radiation-induced breast cancer in women aged 10 or less at the time of exposure (ATE). Both relative and absolute risks are found to be decreased with increasing ages ATE. Based on the above-mentioned findings and other studies on persons exposed medical radiation, radiation-induced breast cancer is characterized by the following: (1) the incidence of breast cancer is linearly increased with increasing radiation doses; (2) both relative and absolute risks for breast cancer are high in younger persons ATE; (3) age distribution of breast cancer in proximally exposed A-bomb survivors is the same as that in both distally A-bomb survivors and non-exposed persons, and there is no difference in histology between the former and latter groups. Thus, immature mammary gland cells before the age of puberty are found to be most radiosensitive. (N.K.)

  8. Matched-pair analysis of patients with female and male breast cancer: a comparative analysis

    International Nuclear Information System (INIS)

    Male breast cancer (MBC) is a rare disease accounting for approximately 1% of all breast carcinomas. Presently treatment recommendations are derived from the standards for female breast cancer. However, those approaches might be inadequate because of distinct gender specific differences in tumor biology of breast cancer. This study was planned in order to contrast potential differences between female and male breast cancer in both tumor biological behavior and clinical management. MBC diagnosed between 1995-2007 (region Chemnitz/Zwickau, Saxony, Germany) was retrospectively analyzed. Tumor characteristics, treatment and follow-up of the patients were documented. In order to highlight potential differences each MBC was matched with a female counterpart (FBC) that showed accordance in at least eight tumor characteristics (year of diagnosis, age, tumor stage, nodal status, grade, estrogen- and progesterone receptors, HER2 status). 108 male/female matched-pairs were available for survival analyses. In our study men and women with breast cancer had similar disease-free (DFS) and overall (OS) survival. The 5-years DFS was 53.4% (95% CI, range 54.1-66.3) in men respectively 62.6% (95% CI, 63.5-75.3) in women (p > 0.05). The 5-years OS was 71.4% (95% CI, 62.1-72.7%) and 70.3% (95% CI, 32.6-49.6) in women (p > 0.05). In males DFS analyses revealed progesterone receptor expression as the only prognostic relevant factor (p = 0.006). In multivariate analyses for OS both advanced tumor size (p = 0.01) and a lack of progesterone receptor expression were correlated (p = 0.01) with poor patients outcome in MBC. Our comparative study revealed no survival differences between male and female breast cancer patients and gives evidence that gender is no predictor for survival in breast cancer. This was shown despite of significant gender specific differences in terms of frequency and intensity of systemic therapy in favor to female breast cancer

    Full Text Available Breast cancer persists as the most common cause of cancer death in women worldwide. Ovarian cancer is also a significant source of morbidity and mortality, as the fifth leading cause of cancer death among women. This reflects the continued need for further understanding and innovation in cancer treatment. Though breast and ovarian cancer usually present as distinct clinical entities, the recent explosion of large-scale -omics research has uncovered many overlaps, particularly with respect to genetic and epigenetic alterations. We compared genetic, microenvironmental, stromal, and epigenetic changes common between breast and ovarian cancer cells, as well as the clinical relevance of these changes. Some of the most striking commonalities include genetic alterations of BRCA1 and 2, TP53, RB1, NF1, FAT3, MYC, PTEN, and PIK3CA; down regulation of miRNAs 9, 100, 125a, 125b, and 214; and epigenetic alterations such as H3K27me3, H3K9me2, H3K9me3, H4K20me3, and H3K4me. These parallels suggest shared features of pathogenesis. Furthermore, preliminary evidence suggests a shared epigenetic mechanism of oncogenesis. These similarities, warrant further investigation in order to ultimately inform development of more effective chemotherapeutics, as well as strategies to circumvent drug resistance.

    Very little is known about the chromosomal regions harbouring genes involved in initiation and progression of BRCAX-associated breast cancers. We applied comparative genomic hybridization (CGH) to identify the most frequent genomic imbalances in 18 BRCAX hereditary breast cancers and compared them to chromosomal aberrations detected in a group of 27 sporadic breast cancers. The aberrations observed most frequently in BRCAX tumours were gains of 8q (83%), 19q (67%), 19p (61%), 20q (61%), 1q (56%), 17q (56%) and losses of 8p (56%), 11q (44%) and 13q (33%). The sporadic cases most frequently showed gains of 1q (67%), 8q (48%), 17q (37%), 16p (33%), 19q (33%) and losses of 11q (26%), 8p (22%) and 16q (19%). Losses of 8p and gains 8q, 19 as well as gains of 20q (with respect to ductal tumours only) were detected significantly more often in BRCAX than in sporadic breast cancers. Analysis of 8p-losses and 8q-gains showed that these aberrations are early events in the tumorigenesis of BRCAX tumors. The findings of this report indicate similarities between BRCAX and BRCA2 tumours, possibly suggesting a common pathway of disease. These findings need confirmation by more extensive studies because only a limited number of cases were analysed and there are relatively few reports published. PMID:15540206

  14. 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

  15. Comparative study on mammography between triple negative and triple positive breast cancer

    International Nuclear Information System (INIS)

    Objective: To analyze the mammographic findings of triple-negative breast cancer [TNBC, which is estrogen receptor (ER) negative, progesterone receptor (PR) negative, and human epidermal growth factor receptor 2 (HER2) negative] and triple-positive breast cancer (TPBC, which is ER positive, PR positive, and HER2 positive), and to evaluate the relationship of immunohistochemologic receptor status and mammographic findings. Methods: The immunohistochemistry results of 631 cases with breast cancers were reviewed, including 117 cases of TNBC and 44 cases of TPBC. All of the patients took mammography at initial diagnosis. We retrospectively evaluated the visibility, morphology, distribution and size of the lesion (masses and calcifications) and breast density on mammography of TNBC, and compared them with those of TPBC. The age onset and tumor sizes of TNBC and TPBC were compared by using Chi-square test and t test. Results: The visibility rate of TNBC and TPBC on mammography were 88.0%(103/117) and 90.9% (40/44), and the difference between them was insignificant (χ2=0.055, P >0.05). TNBC was more frequently associated with merely a mass (56/103) than TPBC (12/40) (χ2=6.860, P<0.01), and the mean diameter of the mass of TNBC [(2.6 ± 1.4) cm] was larger than that of TPBC [(2.0 ± 0.6) cm] (t=2.087, P<0.05). TNBC were less frequently associated with microcalcifications (37/103) than TPBC (24/40) (χ2=7.423, P<0.01). Mammographic density and lesion visibility were similar between the two different immunophenotypes of breast cancers. The mean age of TNBC (52±9) was more than that of TPBC (48 ±8) (t=2.759, P<0.01). Infiltrating ductal carcinoma was the main pathologic type of both groups. Basal-like breast cancer accounted for 49% (57/117) of TNBC while none happened in TPBC. Conclusions: TNBC shows merely a mass with indistinct margins,lager size and is less associated with microcalcifications. These mammographic features might be useful in diagnosing triple negative

  17. Variation in mammographic appearance between projections of small breast cancers compared with radial scars

    International Nuclear Information System (INIS)

    Full text: Aims: The study aims to assess variation in appearance between mammographic projections (conspicuity variation) for invasive breast cancers (IBCs) compared with respect to breast density and the proportion of cases detected by one of two readers and required a third (consensus) read. Materials and methods: The study was approved by the Breast Screen Victoria research committee. Mammograms of 75 randomly selected invasive breast cancers, with histological diameter :510 mm (IBC), were mixed with 67 consecutively detected RS, all from a double-reading population-based breast cancer screening programme. On blinded review, these 142 lesions were classified for mammographic findings and assessed for marked or minor conspicuity variation between views. We assessed the associations between lesion type, lesion spicules and centres, breast density, conspicuity variation and proportion detected by one reader only. Results: Marked conspicuity variation was common, but not statistically different for BC and RS (64% vs. 66%, X2 = 0.8, P = 0.04). Conspicuity variation did not correlate with spiculation type (long, fine or short, broad based) or lesion centres (lucent or dense) (p 2 2.3, P = 0.5; RS, X2 = 0.95, P = 0.6). Density did not vary by lesion type. In the screening programme, 29% of BC (125 of 431) versus 43% of RS (32 of 75) had been detected by one of two readers (X2 2.7, P = 0.098). Conclusions: Two-thirds of small IBCs displayed marked conspicuity variation, similar to RS. Therefore, conspicuity variation does not discriminate between IBC and RS.

    In the Edinburgh Randomised Breast Screening Project (EBSP) to December 1988 there were 500 cancers in the study population invited to screening and 340 cancers identified in the control population. The size and negative lymph node status characteristics of invasive cancers from the two populations were significantly different (P less than 0.05). The cancers detected by screening were predominantly 'early stage', with 16% noninvasive (PTIS) and 42% invasive stage I (pT1 node negative), whereas cancers were frequently 'late stage' (more than pT2) and inoperable in nonattenders (44%) and controls (36%). Grouped according to customary size ranges of invasive cancers, the proportion of cases lymph node positive differed in those screen detected compared with controls, but the benefit in favour of screen detection was not constant. In comparisons of cancers detected at prevalence and incidence screens, as a test of conformity with screening theory, no significant differences were apparent according to size and lymph node status, yet the characteristics of histological type of cancer discriminated significantly (P less than 0.05). When these same histological characteristics were used to compare survival, the capacity to separate invasive cancers into two groups having good and poor survival probabilities was evident, with a significant improvement for the screen detected poor survival group compared with controls (P less than 0.05).

  19. Conspicuity of breast cancer according to histopathological type and breast density when imaged by full-field digital mammography compared with screen-film mammography

    International Nuclear Information System (INIS)

    To compare the conspicuity of different histopathological types of breast cancer according to breast density and mammographic imaging in patients with screen-detected breast cancers undergoing both full-field digital mammography (FFDM) and screen-film mammography (SFM) in the United Kingdom National Health Service Breast Screening Programme (NHSBSP). 185 patients underwent routine screening with SFM followed by further imaging using FFDM with consequent diagnosis of breast cancer. All SFM and soft-copy FFDM images were evaluated by two readers in an independent, retrospective review. The visualisation and conspicuity of the mammographic abnormality were recorded and graded using a four-level scale. Conspicuity of breast cancer was qualitatively evaluated. Breast density and conspicuity were correlated with histopathological diagnosis and inter-observer correlation was calculated. Mixed Model ANOVA demonstrated significant differences between FFDM and SFM (p < 0.001) and breast densities (p = 0.009): conspicuity of the mammographic abnormality (p < 0.001) and visualisation of the dominant mammographic feature (p < 0.001) were significantly greater with FFDM than SFM. This held true for both readers and for all histopathological tumour types with no significant differences between each tumour type. FFDM is significantly superior to SFM for conspicuity of screen-detected breast cancers for all histopathological types and breast densities. (orig.)

    Screening guidelines recommend that women with 20 % or greater lifetime risk of breast cancer undergo annual breast MRI screening to supplement mammography, irrespective of age. In patients less than 40 years, mammography is often avoided due to concerns about radiation and decreased performance. However, prior studies have been limited by large percentages of women above 40 with decreased breast density. Our purpose was to test whether adding mammography to breast MRI screening compared to breast MRI screening alone in women below 40 increases cancer detection rates. After obtaining IRB approval, chart review identified patients aged 25-40 years undergoing breast MR screening (2005-2014). Demographics, risk factors, BI-RADS assessments, background parenchymal enhancement, and mammographic breast tissue density were recorded. Cancer detection rates, short-term follow-up (BIRADS 3), image-guided biopsy (BIRADS 4,5), and PPV1-3 were calculated. 342 breast MRI exams were identified (average age was 33, 37 % were nulliparous, and 64 % had prior benign biopsy), 226 (66 %) of which underwent concurrent mammography. Risk factors included 64 % with breast cancer in first-degree relative(s), 90 % had heterogeneous or extremely dense breast tissue on mammography, and 16 % were BRCA carriers. Four invasive cancers were detected by MRI (11.7 cancers/1000 examinations, 95 % CI 8.3, 15.1). None of these was detected by mammography, and no cancers were independently identified by mammography. Breast MRI screening in high-risk women under 40 yielded elevated cancer detection rates (11.7/1000). The cancer detection rate for mammography was 0 %, suggesting that MRI alone may be useful in screening high-risk women under 40. PMID:27444927

    Background Breast conserving surgery (BCS) has been the standard surgical procedure for the treatment of early breast cancer. Endoscopic subcutaneous mastectomy (ESM) plus immediate reconstruction with implants is an emerging procedure. The objective of this prospective study was to evaluate the clinical outcomes of these two surgical procedures in our clinical setting.Methods From March 2004 to October 2007, 43 patients with breast cancer underwent ESM plus axillary lymph node dissection and immediate reconstruction with implants, while 54 patients underwent BCS. The clinical and pathological characteristics, surgical safety, and therapeutic effects were compared between the two groups. Results There were no significant differences in the age, clinical stage, histopathologic type of tumor, operative blood loss, postoperative drainage time, and postoperative complications between the two groups (P>0.05).The postoperative complications were partial necrosis of the nipple and superficial skin flap in the ESM patients, and hydrops in the axilla and residual cavity in the BCS patients. There was no significant difference in the rate of satisfactory postoperative cosmetic outcomes between the ESM (88.4%, 38/43) and BCS (92.6%, 50/54) patients (P>0.05). During follow-up of 6 months to 4 years, all patients treated with ESM were disease-free, but 3 patients who underwent BCS had metastasis or recurrence-one of these patients died of multiple organ metastasis.Conclusions After considering the wide Indications for use, high surgical safety, and favorable cosmetic outcomes, we conclude that ESM plus axillary lymph node dissection and immediate reconstruction with implants-the new surgery of choice for breast cancer-warrants serious consideration as the prospective next standard surgical procedure.

    Tamoxifen and anastrozole are widely used as adjuvant treatment for early stage breast cancer, but their hepatotoxicity is not fully defined. We aimed to compare hepatotoxicity of anastrozole with tamoxifen in the adjuvant setting in postmenopausal breast cancer patients. Three hundred and fifty-three Chinese postmenopausal women with hormone receptor-positive early breast cancer were randomized to anastrozole or tamoxifen after optimal primary therapy. The primary end-point was fatty liver disease, defined as a liver–spleen ratio <0.9 as determined using a computed tomography scan. The secondary end-points included abnormal liver function and treatment failure during the 3-year follow up. The cumulative incidence of fatty liver disease after 3 years was lower in the anastrozole arm than that of tamoxifen (14.6% vs 41.1%, P < 0.0001; relative risk, 0.30; 95% CI, 0.21–0.45). However, there was no difference in the cumulative incidence of abnormal liver function (24.6% vs 24.7%, P = 0.61). Interestingly, a higher treatment failure rate was observed in the tamoxifen arm compared with anastrozole and median times to treatment failure were 15.1 months and 37.1 months, respectively (P < 0.0001; HR, 0.27; 95% CI, 0.20–0.37). The most commonly reported adverse events were ‘reproductive system disorders’ in the tamoxifen group (17.1%), and ‘musculoskeletal disorders’ in the anastrozole group (14.6%). Postmenopausal women with hormone receptor-positive breast cancer receiving adjuvant anastrozole displayed less fatty liver disease, suggesting that this drug had a more favorable hepatic safety profile than tamoxifen and may be preferred for patients with potential hepatic dysfunction.

    Breast cancer is the most frequently diagnosed cancer of women in North America. Despite advances in treatment that have reduced mortality, breast cancer remains the second leading cause of cancer induced death. Several well established tools are used to screen for breast cancer including clinical breast exams, mammograms, and ultrasound. Thermography was first introduced as a screening tool in 1956 and was initially well accepted. However, after a 1977 study found thermography to lag behind other screening tools, the medical community lost interest in this diagnostic approach. This review discusses each screening tool with a focus brought to thermography. No single tool provides excellent predictability; however, a combination that incorporates thermography may boost both sensitivity and specificity. In light of technological advances and maturation of the thermographic industry, additional research is required to confirm the potential of this technology to provide an effective non-invasive, low risk adjunctive tool for the early detection of breast cancer.

    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 Purpose: Intensity modulated radiotherapy (IMRT and volumetric modulated arc therapy (VMAT has the capacity to optimize the dose distribution. We analyzed the dosimetric differences of plans in treatment planning system (TPS between VMAT and IMRT in treating breast cancer. Methods: Fourteen patients were simulated, planned, and treated with VMAT using single, double or partial arcs. IMRT treatments were generated using 4 to 5 tangential IMRT fields for the same patients. All treatment plans were planned for 50 Gy in 25 fractions. The VMAT and IMRT plans were compared using the planning target volume (PTV dose and doses to the other organs at risk (OARs. Results: For the PTV, comparable minimum, mean, maximum, median, and modal dose as well equivalent sphere diameter of the structure (Equis were observed between VMAT and IMRT plans and found that these values were significantly equal in both techniques. The right lung mean and modal doses were considerably higher in VMAT plans while maximum value was considerably lower when compared with IMRT plans. The left lung mean and modal doses were higher with VMAT while maximum doses were higher in IMRT plans. The mean dose to the heart and maximum dose to the spinal cord was lower with IMRT. The mean dose to the body was higher in VMAT plans while the maximum dose was higher in IMRT plans. Conclusion: Four field tangential IMRT delivered comparable PTV dose with generally less dose to normal tissues in our breast cancer treatment study. The IMRT plans typically had more favourable dose characteristics to the lung, heart, and spinal cord and body dose when compared with VMAT. The only minor advantage of VMAT for breast cases was slightly better PTV coverage.

  19. A comparative study of breast cancer mass screening using ultrasonography and mammography at a single institution

    International Nuclear Information System (INIS)

    In order to evaluate the effectiveness of ultrasonic screening for breast cancer (US group) in comparison with mammographic screening (MMG group), we analyzed 78,214 breast screening examinees presenting between 2007 and 2008 at our institution. The cancer detection rate in the US group was lower than that in the MMG group. However, the average age in the US group was significantly younger than that in the MMG group, and the rate of annual screening was significantly higher in the former than in the latter. In the US subgroup who underwent annual screening, the recall rate and the cancer detection rate were significantly lower, and the rate of detection of early breast cancers was significantly higher than that in the subgroup who underwent screening biennially or at longer intervals, and there was no significant inter-group difference in the cancer detection rate between women in their 40s and those aged 50 or above who underwent annual screening. The proportion of early breast cancers detected was almost the same in the both groups. In summary, US screening as well as MMG screening seems to be useful for detection of early breast cancer. Although a high recall rate for US screening has been reported previously, annual screening and sufficient quality control based on the guidelines proposed by the Japan Association of Breast and Thyroid Sonology (JABTS) are considered to reduce the recall rate.

    Full Text Available Abstract Background Use of complementary and alternative medicine (CAM by women with breast cancer is often said to be increasing, yet few data exist to confirm this commonly held belief. The purpose of this paper is to compare overall patterns of CAM use, as well as use of specific products and therapies at two different points in time (1998 vs 2005 by women diagnosed with breast cancer. Methods Surveys were mailed to women randomly selected from the Ontario Cancer Registry (Canada in the spring of 1998 (n = 557 and again in the spring of 2005(n = 877. Results The response rates were 76.3% in 1998 and 63% in 2005. In 1998, 66.7% of women reported using either a CAM product/therapy or seeing a CAM therapist at some time in their lives as compared with 81.9% in 2005 (p = 0.0002. Increases were seen in both use of CAM products/therapies (62% in 1998 vs. 70.6% in 2005 and visits to CAM practitioners (39.4% of respondents in 1998 vs 57.4% of respondents in 2005. Women in 2005 reported that 41% used CAM for treating their breast cancer. The most commonly used products and practitioners for treating breast cancer as reported in 2005 were green tea, vitamin E, flaxseed, vitamin C, massage therapists and dietitians/nutritionists. Conclusion CAM use (both self-medication with products and visits to CAM practitioners increased significantly from 1998 to 2005. Now that more than 80% of all women with breast cancer report using CAM (41% in a specific attempt to management their breast cancer, CAM use can no longer be regarded as an "alternative" or unusual approach to managing breast cancer.

Our aim was to assess the statistical association of DRC level and breast cancer (BC using a case–control epidemiological study in a Hispanic community. Methods We conducted a comparative observational study to assess the validity of DRC in detecting BC in 824 women throughout Puerto Rico. Over a 6-year period, we compared 285 women newly diagnosed with BC to 539 without BC. DRC levels were measured in lymphocytes by means of a host-cell reactivation assay. We assessed the sensitivity, specificity, and association using the receiver operating characteristic curve analysis. Multiple logistic regression-adjusted odds ratios were estimated with 95% confidence level to measure the strength of the association of DRC and BC after adjusting for all confounders simultaneously. Results Compared to women without cancer, women with BC showed an average decrease of 60% in their DRC levels (p p Conclusions Our results support the usefulness of DRC level as a measure of BC risk. Additional studies in other populations are needed to further verify its usefulness.

  7. Postoperative radiotherapy following mastectomy for patients with left-sided breast cancer: A comparative dosimetric study

    International Nuclear Information System (INIS)

    The purposes of this article were to compare the biophysical dosimetry for postmastectomy left-sided breast cancer using 4 different radiotherapy (RT) techniques. In total, 30 patients with left-sided breast cancer were randomly selected for this treatment planning study. They were planned using 4 RT techniques, including the following: (1) 3-dimensional conventional tangential fields (TFs), (2) tangential intensity-modulated therapy (T-IMRT), (3) 4 fields IMRT (4F-IMRT), and (4) single arc volumetric-modulated arc therapy (S-VMAT). The planning target volume (PTV) dose was prescribed 50 Gy, the comparison of target dose distribution, conformity index, homogeneity index, dose to organs at risk (OARs), tumor control probability (TCP), normal tissue complication probability (NTCP), and number of monitor units (MUs) between 4 plans were investigated for their biophysical dosimetric difference. The target conformity and homogeneity of S-VMAT were better than the other 3 kinds of plans, but increased the volume of OARs receiving low dose (V5). TCP of PTV and NTCP of the left lung showed no statistically significant difference in 4 plans. 4F-IMRT plan was superior in terms of target coverage and protection of OARs and demonstrated significant advantages in decreasing the NTCP of heart by 0.07, 0.03, and 0.05 compared with TFs, T-IMRT, and S-VMAT plan. Compared with other 3 plans, TFs reduced the average number of MUs. Of the 4 techniques studied, this analysis supports 4F-IMRT as the most appropriate balance of target coverage and normal tissue sparing

  12. Comparative actions of progesterone, medroxyprogesterone acetate, drospirenone and nestorone on breast cancer cell migration and invasion

    2008-06-01

    Full Text Available Abstract Background Limited information is available on the effects of progestins on breast cancer progression and metastasis. Cell migration and invasion are central for these processes, and require dynamic cytoskeletal and cell membrane rearrangements for cell motility to be enacted. Methods We investigated the effects of progesterone (P, medroxyprogesterone acetate (MPA, drospirenone (DRSP and nestorone (NES alone or with 17β-estradiol (E2 on T47-D breast cancer cell migration and invasion and we linked some of these actions to the regulation of the actin-regulatory protein, moesin and to cytoskeletal remodeling. Results Breast cancer cell horizontal migration and invasion of three-dimensional matrices are enhanced by all the progestins, but differences are found in terms of potency, with MPA being the most effective and DRSP being the least. This is related to the differential ability of the progestins to activate the actin-binding protein moesin, leading to distinct effects on actin cytoskeleton remodeling and on the formation of cell membrane structures that mediate cell movement. E2 also induces actin remodeling through moesin activation. However, the addition of some progestins partially offsets the action of estradiol on cell migration and invasion of breast cancer cells. Conclusion These results imply that P, MPA, DRSP and NES alone or in combination with E2 enhance the ability of breast cancer cells to move in the surrounding environment. However, these progestins show different potencies and to some extent use distinct intracellular intermediates to drive moesin activation and actin remodeling. These findings support the concept that each progestin acts differently on breast cancer cells, which may have relevant clinical implications.

  17. Breast cancer detection using high-resolution breast PET compared to whole-body PET or PET/CT

    International Nuclear Information System (INIS)

    To compare the performance characteristics of positron emission mammography (PEM) with those of whole-body PET (WBPET) and PET/CT in women with newly diagnosed breast cancer. A total of 178 women consented to PEM for presurgical planning in an IRB-approved protocol and also underwent either WBPET (n = 69) or PET/CT (n = 109) imaging, as per usual care at three centers. Tumor detection sensitivity, positive predictive values, and 18F-fluorodeoxyglucose (FDG) uptake were compared between the modalities. The effects of tumor size, type, and grade on detection were examined. The chi-squared or Fisher's exact tests were used to compare distributions between groups, and McNemar's test was used to compare distributions for paired data within subject groups, i.e. PEM versus WBPET or PEM versus PET/CT. The mean age of the women was 59 ± 12 years (median 60 years, range 26-89 years), with a mean invasive index tumor size of 1.6 ± 0.8 cm (median 1.5 cm, range 0.5-4.0 cm). PEM detected more index tumors (61/66, 92 %) than WBPET (37/66, 56 %; p < 0.001) or PET/CT (95/109, 87 % vs. 104/109, 95 % for PEM; p < 0.029). Sensitivity for the detection of additional ipsilateral malignancies was also greater with PEM (7/15, 47 %) than with WBPET (1/15, 6.7 %; p = 0.014) or PET/CT (3/23, 13 % vs. 13/23, 57 % for PEM; p = 0.003). Index tumor detection decreased with decreasing invasive tumor size for both WBPET (p = 0.002) and PET/CT (p < 0.001); PEM was not significantly affected (p = 0.20). FDG uptake, quantified in terms of maximum PEM uptake value, was lowest in ductal carcinoma in situ (median 1.5, range 0.7-3.0) and invasive lobular carcinoma (median 1.5, range 0.7-3.4), and highest in grade III invasive ductal carcinoma (median 3.1, range 1.4-12.9). PEM was more sensitive than either WBPET or PET/CT in showing index and additional ipsilateral breast tumors and remained highly sensitive for tumors smaller than 1 cm. (orig.)

    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. Cellular & Molecular Immunology.

  5. Early breast cancer

    International Nuclear Information System (INIS)

    Breast cancer remains a common disease throughout the world. Here we review new knowledge about early breast cancer obtained during the past 5 years. The prognosis of early breast cancer is generally favorable. Especially, ductal carcinoma in situ has been regarded as a non-life-threatening disease. Therefore, early diagnosis and early onset of the treatment has been important. Early age at menarche, late age at first birth, and late age at menopause are related to breast cancer risk. Examination by mammography and ultrasonography is still the most effective means of detection for premenopausal and postmenopausal women, respectively. Additionally, there have been important advances in MRI, sentinel lymph node biopsy, breast-conserving surgery, partial breast irradiation, neoadjuvant systemic therapy, and adjuvant systemic therapy. Another approach to keeping the disease under control is the elucidation of breast cancer's molecular biological features. Assessment of potential molecular targets can lead to early diagnosis and molecular targeted treatment. (author)

    1997-01-01

    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.

    2016-05-01

    Breast cancer makes up a quarter of all cancer in women, which is why research into new diagnostic methods and sample preparations need to be developed at an accelerated pace. Researchers are looking for diagnostic tools to detect when an individual has cancer cells and use that information to see what measurements and approaches can be used to take further diagnostic steps. The most common method of sample preparation is the imbibing of tumor tissue in paraffin, which can produce a background for spectroscopic measurements in the range of 500-3500 cm-1. In this study we demonstrated that proper preparation of paraffin-embedded specimens and the measurement methodology can eliminate paraffin vibration, as was done in the work Depciuch et al. 2015. Thanks to this spectroscopic technique there may become a reliable and accurate method of diagnosing breast cancer based on the evidence found from the prepared samples. The study compared the results obtained through Raman spectroscopy and FTIR (Fourier Transform Infrared) measurements of healthy and cancerous breast tissues that were either embedded in paraffin or deparaffinized. The resulting spectrum and accurate analysis led to the conclusion that the appropriate measurement of the background and the elimination of peaks from the paraffin had the greatest impact on the reliability of results. Furthermore, after the accurate, detailed studies FTIR and Raman spectroscopy on samples of breast tissue that were deparaffinized or embedded in paraffin, including a complete analysis of the peak after transformation Kramers-Kröning (KK), it was found that sample preparation did not affect the result obtained by measuring the reflectance in the mid-infrared range, and that this only had a minimal effect relating to the intensity obtained by the measurement of the Raman peak. Only in special cases, when Raman spectroscopic methods are used for research to find the peculiarities of the spectra, are deparaffinization recommended

    Neuroendocrine breast cancer is thought to account for about 1% of all breast cancers. This rare type of breast malignancy is more common in older women and presents as a low-grade, slow-growing cancer. The most definitive markers that indicate neuroendocrine carcinoma are the presence of chromogranin, synaptophysin or neuron-specific enolase, in at least 50% of malignant tumour cells. The authors present a case report of an 83-year-old woman, admitted to their institution with right breast l...

    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.

We have reported a higher incidence of HER2 and C-MYC oncogene amplification in breast cancers from A-bomb survivors. The purpose of this study was to clarify the effect of A-bomb radiation exposure on genomic instability (GIN, which is an important hallmark of carcinogenesis, in archival formalin-fixed paraffin-embedded (FFPE tissues of breast cancer by using microarray-comparative genomic hybridization (aCGH. Methods Tumor DNA was extracted from FFPE tissues of invasive ductal cancers from 15 survivors who were exposed at 1.5 km or less from the hypocenter and 13 calendar year-matched non-exposed patients followed by aCGH analysis using a high-density oligonucleotide microarray. The total length of copy number aberrations (CNA was used as an indicator of GIN, and correlation with clinicopathological factors were statistically tested. Results The mean of the derivative log ratio spread (DLRSpread, which estimates the noise by calculating the spread of log ratio differences between consecutive probes for all chromosomes, was 0.54 (range, 0.26 to 1.05.

    The usefulness of TF for detection of breast cancer was investigated and compared with Tc-99m Sestamibi(MIBI). We performed scintimammography(SM) in a total of 55 patients with breast tumors, 28 patients underwent MIBI SM other 27 patients underwent TF SM. Sensitivity, specificity, and accuracy values obtained with MIBI and TF SM for breast cancer were 73.7%, 58.9%, 83.9% and 70.6%, 61.1% and 83.3%, respectively. Also we investigated whether early imaging with TF may be used for evaluating Pgp status in breast cancer patients. Fifteen patients with breast cancer were evaluated. Tumor/background ratio(T/Bg) and washout rates(WR) were calculated, which were compared with the amount of Pgp staining in tumour cells. The average WR were 0.35±0.09. The WR demostrated significant correlation with the amount of Pgp expression (rho=0.73, p<0.01). TF was effective in detecting breast cancer. TF washout at 1hr showed good correlation with the amount of Pgp. Thus 1hr delay imaging with TF may suffice for evaluating Pgp status in breast cancer patients

    Full Text Available Sentinel lymph node biopsy (SLNB is routinely used in the staging of invasive breast cancer. The aim of this study was to investigate the diagnostic accuracy of ultrasonography (US compared to magnetic resonance imaging (MRI in the pre-operative assessment of metastatic disease to the axilla in breast cancer patients at our community hospital. We retrospectively reviewed a prospectively collected database of 277 patients seen at our breast center from 2009 to 2010. Patients with invasive breast cancer were then evaluated for axillary metastasis. Lymph nodes were sampled using fine needle aspiration (FNAB or core biopsy. Histopathology of the sentinel lymph nodes (SLN or results of the axillary dissection were compared to US or MRI results. A total of 228 patients had invasive breast cancer. In these patients, 122 lymph nodes were sampled. Pathology proven metastases to axillary lymph nodes were found in 76 cases. Accuracy and sensitivity were higher in US than MRI in detecting metastatic disease to the axilla (70.2%, 84.6%, P<0.001 and 60.0%, 52.6%, P <0.1, respectively. US was more accurate than MRI at detecting metastatic breast cancer in the axilla in our community hospital. Axillary US should be a routine part of assessment of breast cancer patients.

  12. Pregnancy After Breast Cancer.

    1999-05-01

    BACKGROUND: The issue of pregnancy following the diagnosis and treatment of breast cancer is important because the incidence of breast cancer is increasing in women of childbearing age. The fact that many women are delaying childbearing, whether for educational, professional, or personal reasons, increases the number of women who will undergo breast cancer treatment before completing childbearing. METHODS: Data on pregnancy in breast cancer survivors are limited and consist only of retrospective data. This paper reviews the published literature on the influence of subsequent pregnancy on breast cancer, including three recent large-scale population-based studies. RESULTS: The survival of women with breast carcinoma who subsequently become pregnant is not reported to be decreased in any of the published series. However, several biases may be present that justify the concern regarding the conclusions. CONCLUSIONS: Further research on the safety of subsequent pregnancy after breast carcinoma treatment is needed. To address these issues, patients are currently being accrued for a large, prospective, multicenter study of young breast carcinoma patients. PMID:10758557

    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.

  14. Dosimetric study comparing volumetric arc modulation with RapidArc and fixed dynamic intensity-modulated radiation therapy for breast cancer radiotherapy after breast-conserving surgery

    International Nuclear Information System (INIS)

    Objective: To compare the dosimetric difference between volumetric are modulation with RapidArc and fixed field dynamic IMRT for breast cancer radiotherapy after breast-conserving surgery. Methods: Twenty patients with early left-sided breast cancer received radiotherapy after breast-conserving surgery. After target definition, treatment planning was performed by RapidArc and two fixed fields dynamic IMRT respectively on the same CT scan. The target dose distribution, homogeneity of the breast, and the irradiation dose and volume for the lungs, heart, and contralateral breast were read in the dose-volume histogram (DVH) and compared between RapidArc and IMRT. The treatment delivery time and monitor units were also compared. Results: In comparison with the IMRT planning,the homogeneity of clinical target volume (CTV), the volume proportion of 95% prescribed dose (V95%) was significantly higher by 0.65% in RapidArc (t=5.16, P=0.001), and the V105% and V110% were lower by 10.96% and 1.48 % respectively, however, without statistical significance (t=-2.05, P=0.055 and t=-1.33, P=0.197). The conformal index of planning target volume (PTV) by the RapidArc planning was (0.88±0.02), significantly higher than that by the IMRT planning [(0.74±0.03), t=18.54, P<0.001]. The homogeneity index (HI) of PTV by the RapidArc planning was 1.11±0.01, significantly lower than that by the IMRT planning (1.12±0.02, t=-2.44, P=0.02). There were no significant differences in the maximum dose (Dmax) and V20 for the ipsilateral lung between the RapidArc and IMRT planning, but the values of V10, V5, Dmin and Dmean by RapidArc planning were all significantly higher than those by the IMRT planning (all P<0.01). The values of max dose and V30 for the heart were similar by both techniques, but the values of V10 and V5 by the RapidArc planning were significantly higher (by 18% and 50%, respectively). The V5 of the contralateral breast and lung by the RapidArc planning were increased by 9

  16. Studies Comparing Screen-Film Mammography and Full-Field Digital Mammography in Breast Cancer Screening: Updated Review

    International Nuclear Information System (INIS)

    Full-field digital mammography (FFDM) has several potential benefits as compared with screen-film mammography (SFM) in mammography screening. Digital technology also opens for implementation of advanced applications, including computer-aided detection (CAD) and tomosynthesis. Phantom studies and experimental clinical studies have shown that FFDM is equal or slightly superior to SFM for detection and characterization of mammographic abnormalities. Despite obvious advantages, the conversion to digital mammography has been slower than anticipated, and not only due to higher costs. Until very recently, some countries did not even permit the use of digital mammography in breast cancer screening. The reason for this reluctant attitude was concern about lower spatial resolution and about using soft-copy reading. Furthermore, there was a lack of data supporting improved diagnostic accuracy using FFDM in a screening setting, since two pioneer trials both showed nonsignificantly lower cancer detection rate at FFDM. The 10 studies comparing FFDM and SFM in mammography screening published so far have shown divergent and rather conflicting results. Nevertheless, there is a rapid conversion to digital mammography in breast cancer screening in many western countries. The aim of this article is to give an updated review of these studies, discuss the conflicting findings, and draw some conclusions from the results

    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.

    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.

    Nanomedicine formulations such as biodegradable nanoparticles (nps) and liposomes offer several advantages over traditional routes of administration: due to their small size, nanocarriers are able to selectively accumulate inside tumours or inflammatory tissues, resulting in improved drug efficacy and reduced side effects. To further augment targeting ability of nanoparticles towards tumour cells, specific ligands or antibodies that selectively recognise biomarkers over-expressed on cancer cells, can be attached to the surface either by chemical bond or by hydrophilic/hydrophobic interactions. In the present work, Herceptin (HER), a monoclonal antibody (mAb) able to selectively recognise HER-2 over-expressing tumour cells (such as breast and ovarian cancer cells), was absorbed on the surface of nanoparticles through hydrophilic/hydrophobic interactions. Nps were prepared by a modified single emulsion solvent evaporation method with five different polymers: three commercial polyesters (poly(ε-caprolactone) (PCL), poly (D,L-lactide) (PLA) and poly (D,L-lactide-co-.glycolide) (PLGA)) and two novel biodegradable polyesterurethanes (PURs) based on Poly(ε-caprolactone) blocks, synthesised with different chain extenders (1,4-cyclohexane dimethanol (CDM) and N-Boc-serinol). Polyurethanes were introduced as matrix-forming materials for nanoparticles due to their high chemical versatility, which allows tailoring of the materials final properties by properly selecting the reagents. All nps exhibited a small size and negative surface charge, suitable for surface functionalisation with mAb through hydrophilic/hydrophobic interactions. The extent of cellular internalisation was tested on two different cell lines: MCF-7 and SK-BR-3 breast cancer cells showing a normal and a high expression of the HER-2 receptor, respectively. Paclitaxel, a model anti-neoplastic drug, was encapsulated inside all nps, and release profiles and cytotoxicity on SK-BR-3 cells were also assessed

    Highlights: • The unique protein expression profiles were found that separate radiosensitive from normal sensitive breast cancer patients. • The oxidative stress response, coagulation properties and acute phase response suggested to be the hallmarks of radiation sensitivity. - Abstract: Radiation therapy is a cornerstone of modern cancer treatment. Understanding the mechanisms behind normal tissue sensitivity is essential in order to minimize adverse side effects and yet to prevent local cancer reoccurrence. The aim of this study was to identify biomarkers of radiation sensitivity to enable personalized cancer treatment. To investigate the mechanisms behind radiation sensitivity a pilot study was made where eight radiation-sensitive and nine normo-sensitive patients were selected from a cohort of 2914 breast cancer patients, based on acute tissue reactions after radiation therapy. Whole blood was sampled and irradiated in vitro with 0, 1, or 150 mGy followed by 3 h incubation at 37 °C. The leukocytes of the two groups were isolated, pooled and protein expression profiles were investigated using isotope-coded protein labeling method (ICPL). First, leukocytes from the in vitro irradiated whole blood from normo-sensitive and extremely sensitive patients were compared to the non-irradiated controls. To validate this first study a second ICPL analysis comparing only the non-irradiated samples was conducted. Both approaches showed unique proteomic signatures separating the two groups at the basal level and after doses of 1 and 150 mGy. Pathway analyses of both proteomic approaches suggest that oxidative stress response, coagulation properties and acute phase response are hallmarks of radiation sensitivity supporting our previous study on oxidative stress response. This investigation provides unique characteristics of radiation sensitivity essential for individualized radiation therapy.

    Full Text Available The possible role of viruses in breast cancer etiology remains an unresolved question. We hypothesized that if some viruses are involved, it may be in a subgroup of breast cancers only. Epidemiological arguments drove our interest in breast cancer subgroups that are more frequent in Africa, namely inflammatory breast cancer (IBC and triple-negative breast cancer. We tested whether viral prevalence was significantly higher in these subgroups.One hundred fifty-five paraffin-embedded malignant breast tumors were randomly selected at the pathology laboratory of the University Hospital of Annaba (Algeria to include one third of IBC and two thirds of non-IBC. They were tested for the presence of DNA from 61 viral agents (46 human papillomaviruses, 10 polyomaviruses, and 5 herpesviruses using type-specific multiplex genotyping assays, which combine multiplex PCR and bead-based Luminex technology.Viral DNA was found in 22 (17.9% of 123 tumors. The most prevalent viruses were EBV1 and HPV16. IBC tumors carried significantly more viruses (any type than non-IBC tumors (30% vs. 13%, p<0.04. Similarly, triple-negative tumors displayed higher virus-positivity than non-triple-negative tumors (44% vs. 14%, p<0.009.Our results suggest an association between the presence of viral DNA and aggressive breast cancer phenotypes (IBC, triple-negative. While preliminary, they underline the importance of focusing on subgroups when studying viral etiology in breast cancer. Further studies on viruses in breast cancer should be conducted in much larger samples to confirm these initial findings.

    Objective:To explore the efficacy of tamoxifen and letrozole in the adjuvant hormonal therapy of postmenopausal breast cancer.Methods:A total of 60 patients with postmenopausal breast cancer who were admitted in our hospital from May, 2012 to May, 2015 were included in the study and randomized into the observation group and the control group. The patients in the observation group were given letrozole, while the patients in the control group were given tamoxifen. The change of serum VEGF level before and after treatment, the mass shrinking degree after treatment, and the change of tumor grading in the two groups were observed. The clinical efficacy and adverse reactions were compared.Results:After treatment, the serum VEGF level in the observation group [(145.79±41.28) pg/mL] was significantly lower than that in the control group [(214.62±53.51) pg/mL]. The mass shrinking degree in the observation group (56.89±15.43) was significantly greater than that in the control group (45.17±11.16). In the tumor grading, 46.67% (14/30) at stage I in the observation group was significantly greater than that in the control group [13.33% (4/30)], 13.33% (4/30) at stage III significantly less than that in the control group [36.67% (11/30)] . The total response rate in the observation group [90.00% (27/30)] was significantly higher than that in the control group [66.66% (20/30)]. Conclusions:In the neoadjuvant endocrine therapy of postmenopausal breast cancer, letrozole has a better effect than tamoxifen, and can significantly reduce the tumor grading; therefore, it deserves to be widely recommended in the clinic.

    Viruses are the accepted cause of many important cancers including cancers of the cervix and anogenital area, the liver, some lymphomas, head and neck cancers and indirectly human immunodeficiency virus associated cancers. 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. This is potentially good news as effective vaccines are already available to prevent infections from carcinogenic strains of human papilloma virus, which causes cancer of the uterine cervix

  1. Comparative accuracy of different techniques in planning radiation therapy of breast cancer

    International Nuclear Information System (INIS)

    The authors report the results of the analysis of several factors contributing to the accuracy of treatment planning in the radiation therapy of breast cancer. Different techniques (non-radiological vs CT-based) were used for the acquisition of patients' data; different methods (manual vs computerized) were employed for dose calculation. As for geometric parameters describing the external outline and target volume, mean differences were lower than 4%. Switching from a completely manual method to a CT-based one with computerized calculation, a 3.56% mean decrease in the value of reference isodose (p<0.01) was observed, togheter with a 3.87% mean increase in the estimated inhomogeneity (p<0.001). The non-CT-based outline of target volume exhibited geographic missing of inner portions of the target in 8/16 patients. Our results demonstarte that treatment planning procedures can be a significant source of clinically relevant inaccuracy, which may affect treatment outcome and tumor control

  2. Treatment choices in breast cancer: a comparative analysis of mastectomy patients and radiation patients

    International Nuclear Information System (INIS)

    This descriptive-exploratory study identified factors that distinguished women on the basis of the treatment they chose for breast cancer. A semi-structured interview and questionnaire was administered to 30 respondents who received mastectomy and 31 who received lumpectomy with radiation. The variables investigated as potential predictors of treatment choice were (1) participation in treatment planning, (2) knowledge of illness and treatment alternatives, (3) health locus of control, (4) sex-role identification, (5) body image, (6) social support and (7) age. As perceptions of the outcome of treatment influence attitudes about treatment choice, five variables relating to perceived treatment consequences were also examined. These were (1) social support, (2) body image, (3) satisfaction with medical care, (4) satisfaction with treatment and (5) general well-being. The major findings in regard to the predictor variables included a profile of the characteristics of each group. The radiation group had more knowledge, participated in planning to a greater extent, investigated treatment options more often and typically made their own decisions about treatment. The mastectomy group was older, attributed locus of control to chance and demonstrated nonsignificant trends toward locus of control in powerful others and toward a feminine sex-role identification; 50% cited Surgeon's Advice as the basis of their choice

    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.

    Patient-centered decision making about hot flash treatments often incorporates a balance of efficacy and side effects in addition to patient preference. This systematic review examines randomized controlled trials (RCTs) comparing at least two non-hormonal hot flash treatments in breast cancer survivors. In July 2015, PubMed, SCOPUS, CINAHL, Cochrane, and Web of Science databases were searched for RCTs comparing active, non-hormonal hot flash treatments in female breast cancer survivors. Thirteen trials were included after identifying 906 potential studies. Four trials were dose comparison studies of pharmacologic treatments citalopram, venlafaxine, gabapentin, and paroxetine. Hot flash reduction did not differ by tamoxifen or aromatase inhibitor use. Citalopram 10, 20, and 30 mg daily had comparable outcomes. Venlafaxine 75 mg daily improved hot flashes without additional side effects from higher dosing. Gabapentin 900 mg daily improved hot flashes more than 300 mg. Paroxetine 10 mg daily had fewer side effects than 20 mg. Among four trials comparing different pharmacologic treatments, venlafaxine alleviated hot flash symptoms faster than clonidine; participants preferred venlafaxine over gabapentin. Five trials compared pharmacologic to non-pharmacologic treatments. Acupuncture had similar efficacy to venlafaxine and gabapentin but may have longer durability after completing treatment and fewer side effects. We could not perform a pooled meta-analysis because outcomes were not reported in comparable formats. Clinical trial data on non-hormonal hot flash treatments provide comparisons of hot flash efficacy and other patient important outcomes to guide clinical management. Clinicians can use the information to help patients select hot flash interventions. PMID:27015968

    Full Text Available Trials with tamoxifen have clearly shown that the risk of developing oestrogen receptor positive breast cancer can be reduced by at least 50% with prophylactic agents. The current challenge is to find new agents which achieve this or better efficacy, but with fewer side effects. Recent results indicate that the SERM raloxifene has similar efficacy to tamoxifen, but leads to fewer endometrial cancers, gynecological symptoms, and thromboembolic events. Results for contralateral tumors in adjuvant trials suggest that aromatase inhibitors may be able to prevent up to 70%–80% of ER-positive breast cancers, and this is currently being investigated in two large prevention trials, one using anastrozole (IBIS-II and the other exemestane (MAP.3. New agents are needed for receptor negative breast cancer and several possibilities are currently under investigation.

    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

  12. Tangential vs. defined radiotherapy in early breast cancer treatment without axillary lymph node dissection. A comparative study

    International Nuclear Information System (INIS)

    Recent studies have demonstrated low regional recurrence rates in early-stage breast cancer omitting axillary lymph node dissection (ALND) in patients who have positive nodes in sentinel lymph node dissection (SLND). This finding has triggered an active discussion about the effect of radiotherapy within this approach. The purpose of this study was to analyze the dose distribution in the axilla in standard tangential radiotherapy (SRT) for breast cancer and the effects on normal tissue exposure when anatomic level I-III axillary lymph node areas are included in the tangential radiotherapy field configuration. We prospectively analyzed the dosimetric treatment plans from 51 consecutive women with early-stage breast cancer undergoing radiotherapy. We compared and analyzed the SRT and the defined radiotherapy (DRT) methods for each patient. The clinical target volume (CTV) of SRT included the breast tissue without specific contouring of lymph node areas, whereas the CTV of DRT included the level I-III lymph node areas. We evaluated the dose given in SRT covering the axillary lymph node areas of level I-III as contoured in DRT. The mean VD95% of the entire level I-III lymph node area in SRT was 50.28 % (range, 37.31-63.24 %), VD45Gy was 70.1 % (54.8-85.4 %), and VD40Gy was 83.5 % (72.3-94.8 %). A significant difference was observed between lung dose and heart toxicity in SRT vs. DRT. The V20Gy and V30Gy of the right and the left lung in DRT were significantly higher in DRT than in SRT (p < 0.001). The mean heart dose in SRT was significantly lower (3.93 vs. 4.72 Gy, p = 0.005). We demonstrated a relevant dose exposure of the axilla in SRT that should substantially reduce local recurrences. Furthermore, we demonstrated a significant increase in lung and heart exposure when including the axillary lymph nodes regions in the tangential radiotherapy field set-up. (orig.)

    Full Text Available Abstract Background NUCKS (Nuclear, Casein Kinase and Cyclin-dependent Kinase Substrate is a nuclear, DNA-binding and highly phosphorylated protein. A number of reports show that NUCKS is highly expressed on the level of mRNA in several human cancers, including breast cancer. In this work, NUCKS expression on both RNA and protein levels was studied in breast tissue biopsies consisted of invasive carcinomas, intraductal proliferative lesions, benign epithelial proliferations and fibroadenomas, as well as in primary cultures derived from the above biopsies. Specifically, in order to evaluate the level of NUCKS protein in correlation with the histopathological features of breast disease, immunohistochemistry was employed on paraffin sections of breast biopsies of the above types. In addition, NUCKS expression was studied by means of Reverse Transcription PCR (RT-PCR, real-time PCR (qRT-PCR and Western immunoblot analyses in the primary cell cultures developed from the same biopsies. Results The immunohistochemical Results showed intense NUCKS staining mostly in grade I and II breast carcinomas compared to normal tissues. Furthermore, NUCKS was moderate expressed in benign epithelial proliferations, such as adenosis and sclerosing adenosis, and highly expressed in intraductal lesions, specifically in ductal carcinomas in situ (DCIS. It is worth noting that all the fibroadenoma tissues examined were negative for NUCKS staining. RT-PCR and qRT-PCR showed an increase of NUCKS expression in cells derived from primary cultures of proliferative lesions and cancerous tissues compared to the ones derived from normal breast tissues and fibroadenomas. This increase was also confirmed by Western immunoblot analysis. Although NUCKS is a cell cycle related protein, its expression does not correlate with Ki67 expression, neither in tissue sections nor in primary cell cultures. Conclusion The results show overexpression of the NUCKS protein in a number of non

    Obesity is a risk factor for breast cancer recurrence and death. Women who reside in rural areas have higher obesity prevalence and suffer from breast cancer treatment-related disparities compared to urban women. The objective of this 5-year randomized controlled trial is to compare methods for delivering extended care for weight loss maintenance among rural breast cancer survivors. Group phone-based counseling via conference calls addresses access barriers, is more cost-effective than individual phone counseling, and provides group support which may be ideal for rural breast cancer survivors who are more likely to have unmet support needs. Women (n=210) diagnosed with Stage 0 to III breast cancer in the past 10 years who are ≥ 3 months out from initial cancer treatments, have a BMI 27-45 kg/m(2), and have physician clearance were enrolled from multiple cancer centers. During Phase I (months 0 to 6), all women receive a behavioral weight loss intervention delivered through group phone sessions. Women who successfully lose 5% of weight enter Phase II (months 6 to 18) and are randomized to one of two extended care arms: continued group phone-based treatment or a mail-based newsletter. During Phase III, no contact is made (months 18 to 24). The primary outcome is weight loss maintenance from 6 to 18 months. Secondary outcomes include quality of life, serum biomarkers, and cost-effectiveness. This study will provide essential information on how to reach rural survivors in future efforts to establish weight loss support for breast cancer survivors as a standard of care. PMID:24486636

  18. Randomized controlled trial to evaluate the effects of progressive resistance training compared to progressive muscle relaxation in breast cancer patients undergoing adjuvant radiotherapy: the BEST study

    International Nuclear Information System (INIS)

    Cancer-related fatigue (CRF) is one of the most common and distressing side effects of cancer and its treatment. During and after radiotherapy breast cancer patients often suffer from CRF which frequently impairs quality of life (QoL). Despite the high prevalence of CRF in breast cancer patients and the severe impact on the physical and emotional well-being, effective treatment methods are scarce. Physical activity for breast cancer patients has been reported to decrease fatigue, to improve emotional well-being and to increase physical strength. The pathophysiological and molecular mechanisms of CRF and the molecular-biologic changes induced by exercise, however, are poorly understood. In the BEST trial we aim to assess the effects of resistance training on fatigue, QoL and physical fitness as well as on molecular, immunological and inflammatory changes in breast cancer patients during adjuvant radiotherapy. The BEST study is a prospective randomized, controlled intervention trial investigating the effects of a 12-week supervised progressive resistance training compared to a 12-week supervised muscle relaxation training in 160 patients with breast cancer undergoing adjuvant radiotherapy. To determine the effect of exercise itself beyond potential psychosocial group effects, patients in the control group perform a group-based progressive muscle relaxation training. Main inclusion criterion is histologically confirmed breast cancer stage I-III after lumpectomy or mastectomy with indication for adjuvant radiotherapy. Main exclusion criteria are acute infectious diseases, severe neurological, musculosceletal or cardiorespiratory disorders. The primary endpoint is cancer-related fatigue; secondary endpoints include immunological and inflammatory parameters analyzed in peripheral blood, saliva and urine. In addition, QoL, depression, physical performance and cognitive capacity will be assessed. The BEST study is the first randomized controlled trial comparing progressive

    Consensus is still lacking on guidelines for breast-cancer screening with mammography: who should be screened, how frequently at what age, to what benefits and at what risks. 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 ...

Methods: Cost-effectiveness analysis from a US third-party payer perspective. A 10 year Markov model was developed to estimate costs and effects of using each method of risk assessment. The percentages of patients assessed as high, moderate, or low risk were obtained from multicenter, prospective, randomized controlled trials. The analysis simulated the experience of women progressing through various model states representing clinical treatments and subsequent disease. Published recurrence data for Mammostrat® were adjusted appropriately to account for differences between definitions and samples of Oncotype DX® and Mammostrat® in the original clinical trials. Cost and utility data were obtained from previously published studies. Sensitivity analyses examined how base-case results might differ when input values and assumptions varied. Results: Base-case costs for women assessed using Mammostrat® were $15,782, compared with $18,051 for women assessed with Oncotype DX®. Thus, cost savings of $2,268 resulted from using Mammostrat®. Both Mammostrat® and Oncotype DX® resulted in similar life years (9.880 and 9.882 and quality-adjusted life years (7.935 and 7.940, respectively. Sensitivity analyses demonstrated that the assumptions made about recurrence are the key drivers of model results. Discussion: Cost savings associated with the use of Mammostrat® instead of Oncotype DX® are largely due to the difference in cost between the two tests.

  3. 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

    Expression of proliferating cell nuclear antigen (PCNA) has been shown to be of prognostic value in patients with certain types of cancer. The aim of this study was to determine if the abundance of PCNA is inversely correlated with survival of patients with breast cancer. Paraffin blocks were available from 68 patients, all of whom had been followed clinically for at least 5 years. Sections from 20 patients showed no reactivity to PCNA and were excluded from the study because it was not possible to distinguish between true negatives and false negatives (those due to poor fixation of the original specimens). The PCNA index (the number of stained cancer cells as a percentage of the total number of cancer cells present) was calculated for the remaining 48 patients. Results were analysed by Wilcoxon's rank sum test (two tailed) and Pearson's correlation coefficient. There was no statistical difference between the PCNA indices of those patients dead from their disease within 5 years of diagnosis compared with those alive and without signs of breast cancer at 5 years. There was also no correlation between PCNA index and size of the cancer, involvement of axillary lymph nodes, time to recurrence or time to death. There was, however, a significant correlation between PCNA index and histological grade (P = 0.029). It appears that PCNA staining of stored paraffin sections is of little prognostic value in patients with breast cancer. PMID:8101708

    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

    Breast tumorigenesis proceeds through an accumulation of specific genetic alteration. Breast malignant transformation is dependent on not only the rate of cell production but also on apoptcsis,a genetically prograined process of autonomous ceil death. We investigated whether breast tumorigenesis involved an altered susceptibility to apoptosis and proliferation by examining normal breast epithelium and breast cancer sampies. We found there is a great inhibition of spontaneous apoptosis in breast cancer ceils compared with normal breast epithelium. The inhibition of apoptosis in breast cancer may contribute to neoplastic transformation.

  14. Progestins and breast cancer.

    Pasqualini, Jorge R

    2007-10-01

    Progestins exert their progestational activity by binding to the progesterone receptor (form A, the most active and form B, the less active) and may also interact with other steroid receptors (androgen, glucocorticoid, mineralocorticoid, estrogen). They can have important effects in other tissues besides the endometrium, including the breast, liver, bone and brain. The biological responses of progestins cover a very large domain: lipids, carbohydrates, proteins, water and electrolyte regulation, hemostasis, fibrinolysis, and cardiovascular and immunological systems. At present, more than 200 progestin compounds have been synthesized, but the biological response could be different from one to another depending on their structure, metabolism, receptor affinity, experimental conditions, target tissue or cell line, as well as the biological response considered. There is substantial evidence that mammary cancer tissue contains all the enzymes responsible for the local biosynthesis of estradiol (E(2)) from circulating precursors. Two principal pathways are implicated in the final steps of E(2) formation in breast cancer tissue: the 'aromatase pathway', which transforms androgens into estrogens, and the 'sulfatase pathway', which converts estrone sulfate (E(1)S) into estrone (E(1)) via estrone sulfatase. The final step is the conversion of weak E(1) to the potent biologically active E(2) via reductive 17beta-hydroxysteroid dehydrogenase type 1 activity. It is also well established that steroid sulfotransferases, which convert estrogens into their sulfates, are present in breast cancer tissues. It has been demonstrated that various progestins (e.g. nomegestrol acetate, medrogestone, promegestone) as well as tibolone and their metabolites can block the enzymes involved in E(2) bioformation (sulfatase, 17beta-hydroxysteroid dehydrogenase) in breast cancer cells. These substances can also stimulate the sulfotransferase activity which converts estrogens into the biologically

  18. Screening for breast cancer post reduction mammoplasty

    International Nuclear Information System (INIS)

    Aim: To investigate whether remodelling of the breast after breast reduction surgery has an effect on mammographic cancer detection. Methods and materials: For women who attended population-based screening between January 1998 to December 2007, data were extracted on their age, history of previous breast reduction, and the result of screening (recall for further assessment, cancer, or no cancer). The number of cancers detected, recalls per 1000 screens and the characteristics of the cancers detected in the two groups was compared. Results: In total 244,147 women with 736,219 screening episodes were reviewed. In the 4743 women who had a breast reduction, 51 breast cancers were detected [age standardized rate (ASR) of 4.28 per 1000 screening episodes; 95% CI 3.11-5.46], compared with 4342 breast cancers in 239 404 women screened in the non-reduction group (ASR of 5.99 per 1000 screening episodes; 95% CI 5.81-6.16). There were fewer cancers in the breast reduction group with a relative risk of 0.71. There was no significant difference in the rate of recall between the two groups, with a crude recall rate of 46.1 per 1000 screening episodes post-breast reduction compared with 50.7 per 1000 screening episodes for women without breast reduction. There was no significant difference in the pathological type or location of the cancer between the two groups of women. Conclusion: Postoperative breast changes following reduction mammoplasty do not significantly hinder analysis of the screening mammogram.

    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 Breast cancer is the leading cause of cancer in females between the ages of 15 and 54, and the second leading cause of cancer death in women in the United States. Diagnosis begins with detection by breast examination (clinical breast exam or breast self-exam or by radiologic studies, like mammography. Many advances in the diagnosis of breast cancer have taken place in recent years. This article will review the history of radiologic advances in the diagnosis of breast cancer. Use of technological advancements in digital breast tomosynthesis, magnetic resonance imaging, and ultrasound in breast cancer diagnosis will be presented. Advantages and disadvantages of these diagnostic interventions when compared to older, traditional X-ray films will be discussed. It is important for all nurses, including radiology and oncology nurses, to be well informed about these varied diagnostic modalities, and appreciate the fact that advances in radiologic imaging technologies can yield improved outcomes for breast cancer patients.

    Full Text Available This is a literature review on the aetiology and pathogenesis of breast cancer, which is the most common cancer worldwide, and the second leading cause of cancer death, especially in Western countries. Several aetiological factors have been implicated in its pathogenesis, and include age, genetics, family history, diet, alcohol, obesity, lifestyle, physical inactivity, as well as endocrine factors. These factors act separately or together in the causation of breast cancer. More recently, triple negative breast cancer has been described in certain categories of patients and is associated with poorer prognosis and earlier recurrence compared with the conventional breast cancer. Therefore, adequate knowledge of these factors is important in identifying high risk groups and individuals, which will help in screening, early detection and follow-up. This will help to decrease the morbidity and mortality from this life-threatening disease.

    To compare the usefulness of mammography and clinical examination in the evaluation of residual cancer of locally-advanced breast carcinoma treated with neoadjuvant chemotherapy. Among 67 patients with locally advanced breast carcinoma who were treated with neoadjuvant chemotherapy, 18, aged 35-67 (mean, 48) years, underwent mammography before and after this therapy. The 18 sets of mammographs were analyzed retrospectively and compared with the results of clinical examination based on histologic diagnosis. On histologic examinations, 16 of 18 patients (89%) were found to have residual cancer, but in one of these 16, mammography did not show this same result. On mammography, residual cancer was found in 16 patients, but in one of this group, histologic examination did not reveal the same finding. Clinically, a complete response was shown by four patients, and a partial response by 11 ; three showed no response. On histolgogic examination, three of the four patients with complete clinical response were found to have residual cancer. Post-treatment mammographic findings showed that 11 patients had measurable mass ; all of these had residual cancer (positive predictive value : 100%). However, five of seven patients in whom no measurable mass was evident also had residual cancer. Seven of 8 patients in whom microcalcifications were seen on mammography were found to have residual cancer (positive predictive value : 88%). The sensitivity of mammography in predicting residual cancer was greater than that of clinical examination (94% vs 81%), even when microscopic residual cancer was considered as a complete response (92% vs 77%). The specificity of mammography was the same as that of clinical examination(50% vs 50%, 20% vs 20%). In evaluating residual cancer of locally-advanced breast carcinoma after neoadjuvant chemotheragy, mammography is more accurate and informative than clincal examination. In predicting residual cancer, however, it is not accurate enough to replace

    To evaluate the impact of whole-body {sup 18}F-FDG PET/CT on initial staging of breast cancer in comparison to conventional staging modalities. This study included 102 breast cancer patients, 101 patients were eligible for evaluation. Preoperative whole-body staging with PET/CT was performed in patients with clinical stage ≥ T2 tumours or positive local lymph nodes (n = 91). Postoperative PET/CT was performed in patients without these criteria but positive sentinel lymph node biopsy (n = 10). All patients underwent PET/CT and a conventional staging algorithm, which included bone scan, chest X-ray and abdominal ultrasound. PET/CT findings were compared to conventional staging and the impact on therapeutic management was evaluated. PET/CT led to an upgrade of the N or M stage in overall 19 patients (19 %) and newly identified manifestation of breast cancer in two patients (2 %). PET/CT findings caused a change in treatment of 11 patients (11 %). This is within the range of recent studies, all applying conventional inclusion criteria based on the initial T and N status. PET/CT has a relevant impact on initial staging and treatment of breast cancer when compared to conventional modalities. Further studies should assess inclusion criteria beyond the conventional T and N status, e.g. tumour grading and receptor status. (orig.)

    Breast cancers in BRCA1 gene mutation carriers often have specific histologic features: grade III tumors with pushing margins. Our purpose was to compare the mammographic and histologic features of breast cancers in carriers with those in age-matched sporadic controls. The features of breast cancers in 27 BRCA1 carriers found during annual surveillance were compared to those in 107 age-matched sporadic controls. The carriers had no (classic) spiculated mammographic lesions, a high percentage of well-defined masses and hardly any masses with microcalcifications, whereas the controls had significantly fewer well-defined ones and only in 27% spiculated lesions on the mammogram. The well-defined mammographic tumors correlated in 83% of the carriers and in 70% of the controls with histologic circumscribed tumor margins. Spiculated mammographic lesions in the controls were in 90% grade I or II tumors. DCIS with or without infiltration was seen in 22% of the carriers and in 45% of the controls. In conclusion, breast cancers diagnosed in BRCA1 carriers do not have classic malignant mammographic features. A minority of the young sporadic controls show the classic malignant lesion on the mammogram. Both carriers and controls generally show a good correlation between their mammographic- and histologic tumor pattern. (orig.)

  15. Patients With T1 to T2 Breast Cancer With One to Three Positive Nodes Have Higher Local and Regional Recurrence Risks Compared With Node-Negative Patients After Breast-Conserving Surgery and Whole-Breast Radiotherapy

    International Nuclear Information System (INIS)

    Purpose: To evaluate locoregional recurrence according to nodal status in women with T1 to T2 breast cancer and zero to three positive nodes (0-3N+) treated with breast-conserving surgery (BCS). Methods and Materials: The study subjects comprised 5,688 women referred to the British Columbia Cancer Agency between 1989 and 1999 with pT1 to T2, 0-3N+, M0 breast cancer, who underwent breast-conserving surgery with clear margins and radiotherapy (RT) of the whole breast. The 10-year Kaplan-Meier local, regional, and locoregional recurrence (LR, RR, and LRR, respectively) were compared between the N0 (n = 4,433) and 1-3N+ (n = 1,255) cohorts. The LRR was also examined in patients with one to three positive nodes (1-3N+) treated with and without nodal RT. Multivariate analysis was performed using Cox regression modeling. Results: Median follow-up was 8.6 years. Systemic therapy was used in 97% of 1-3N+ and 41% of N0 patients. Nodal RT was used in 35% of 1-3N+ patients. The 10-year recurrence rates in N0 and 1-3N+ cohorts were as follows: LR 5.1% vs. 5.8% (p = 0.04); RR 2.3% vs. 6.1% (p < 0.001), and LRR 6.7% vs. 10.1% (p < 0.001). Among 817 1-3N+ patients treated without nodal RT, 10-year LRR were 13.8% with age <50 years, 20.3% with Grade III, and 23.4% with estrogen receptor (ER)-negative disease. On multivariate analysis, 1-3N+ status was associated with significantly higher LRR (hazard ratio [HR], 1.85; 95% confidence interval, 1.34-2.55, p < 0.001), whereas nodal RT significantly reduced LRR (HR, 0.59; 95% confidence interval, 0.38-0.92, p = 0.02). Conclusion: Patients with 1-3N+ and young age, Grade III, or ER-negative disease have high LRR risks approximating 15% to 20% despite BCS, whole-breast RT and systemic therapy. These patients may benefit with more comprehensive RT volume encompassing the regional nodes

    Full Text Available Background: The high number of breast cancer patients who receive radiation therapy after surgery has caused many to think about a shorter period of radiotherapy, which can significantly reduce the radiotherapy machine time, labor hours, and fewer patient visits. This study was designed to evaluate the acute skin effects and cosmetic outcomes of short course radiotherapy in early-stage breast cancer in comparison with the conventional treatment method.Methods: Fifty-two patients with operable breast cancer (pT1-3pN0M0 who underwent breast conservation surgery in Tehran Cancer Institute during January 2011 to January 2012, were randomly assigned to undergo radiotherapy by either receiving conventional treatment (dose: 50 Gy in 25 fractions with subsequent electron boost or a short-course hypofractionated radiotherapy (dose: 42.5 Gy in 16 fractions and a subsequent electron boost.Results: There were no skin changes during the first or the second week of treatment in the two groups. Cutaneous complications began after the third week as grade 1 skin toxicity after termination of the short-course radiotherapy but there were no difference in complication rate after four weeks of treatment. Six months and one year after treatment, there were no differences in terms of skin complications or cosmetic outcomes between the two groups.Conclusion: Although the use of a whole-breast irradiation with a hypofractionated schedule was associated with desirable outcomes, in term of skin toxicity and cosmetics, but longer follow-up periods with larger sample sizes are needed to confirm these results.

  19. Dosimetry of breast cancer

    International Nuclear Information System (INIS)

    The systemic therapy of breast cancer has also changed profoundly during the last 60 years, and in this time the integration of treatment modalities involve a major area of investigation. The dosimetry of breast cancer presents different complications which can range from the Physician's handling of the neoplasia up to the simple aspects of physical simulation, contour design, radiation fields, irregular surfaces and computer programs containing mathematical equations which differ little or largely with the reality of the radiation distribution into the volume to be irradiated. We have studied the problem using two types of measurements to determine how the radiation distribution is in irregular surfaces, and designing an easier skill to be used with each patient, in order to optimize the treatment with respect to the simulation and verification process.

    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.

    Full Text Available BACKGROUND: Assessing neighborhood environment in access to mammography remains a challenge when investigating its contextual effect on breast cancer-related outcomes. Studies using different Geographic Information Systems (GIS-based measures reported inconsistent findings. METHODS: We compared GIS-based measures (travel time, service density, and a two-Step Floating Catchment Area method [2SFCA] of access to FDA-accredited mammography facilities in terms of their Spearman correlation, agreement (Kappa and spatial patterns. As an indicator of predictive validity, we examined their association with the odds of late-stage breast cancer using cancer registry data. RESULTS: The accessibility measures indicated considerable variation in correlation, Kappa and spatial pattern. Measures using shortest travel time (or average and service density showed low correlations, no agreement, and different spatial patterns. Both types of measures showed low correlations and little agreement with the 2SFCA measures. Of all measures, only the two measures using 6-timezone-weighted 2SFCA method were associated with increased odds of late-stage breast cancer (quick-distance-decay: odds ratio [OR] = 1.15, 95% confidence interval [CI] = 1.01-1.32; slow-distance-decay: OR = 1.19, 95% CI = 1.03-1.37 after controlling for demographics and neighborhood socioeconomic deprivation. CONCLUSIONS: Various GIS-based measures of access to mammography facilities exist and are not identical in principle and their association with late-stage breast cancer risk. Only the two measures using the 2SFCA method with 6-timezone weighting were associated with increased odds of late-stage breast cancer. These measures incorporate both travel barriers and service competition. Studies may observe different results depending on the measure of accessibility used.

    Breast cancer is the most frequently diagnosed neoplastic disease in women around menopause often leading to a significant reduction of these women's ability to function normally in everyday life. The increased breast cancer incidence observed in epidemiological studies in a group of women actively participating in social and professional life implicates the necessity of conducting multidirectional studies in order to identify risk factors associated with the occurrence of this type of neoplasm. Taking the possibility of influencing the neoplastic transformation process in individuals as a criterion, all the risk factors initiating the process can be divided into two groups. The first group would include inherent factors such as age, sex, race, genetic makeup promoting familial occurrence of the neoplastic disease or the occurrence of benign proliferative lesions of the mammary gland. They all constitute independent parameters and do not undergo simple modification in the course of an individual's life. The second group would include extrinsic factors conditioned by lifestyle, diet or long-term medical intervention such as using oral hormonal contraceptives or hormonal replacement therapy and their influence on the neoplastic process may be modified to a certain degree. Identification of modifiable factors may contribute to development of prevention strategies decreasing breast cancer incidence. PMID:26528110

    With mammography firmly established as an integral part of efforts to reduce breast cancer mortality, many believe it is time to concentrate on prevention. Part of the multifaceted approach to preventing and treating this disease is unraveling its molecular, genetic and physiological makeup. Another aspect is ensuring that women have the information they need to make informed decisions about screening and treatment. Studies also point to the influence of nutrition, exercise, medicines and a patient's adherence to screening on cancer risk and recovery. PMID:20445140

  8. Interleukin-19 in Breast Cancer

    Directory of Open Access Journals (Sweden)

    2013-01-01

    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.

  10. A comparative analysis of 3D conformal deep inspiratory–breath hold and free-breathing intensity-modulated radiation therapy for left-sided breast cancer

    International Nuclear Information System (INIS)

    Patients undergoing radiation for left-sided breast cancer have increased rates of coronary artery disease. Free-breathing intensity-modulated radiation therapy (FB-IMRT) and 3-dimensional conformal deep inspiratory–breath hold (3D-DIBH) reduce cardiac irradiation. The purpose of this study is to compare the dose to organs at risk in FB-IMRT vs 3D-DIBH for patients with left-sided breast cancer. Ten patients with left-sided breast cancer had 2 computed tomography scans: free breathing and voluntary DIBH. Optimization of the IMRT plan was performed on the free-breathing scan using 6 noncoplanar tangential beams. The 3D-DIBH plan was optimized on the DIBH scan and used standard tangents. Mean volumes of the heart, the left anterior descending coronary artery (LAD), the total lung, and the right breast receiving 5% to 95% (5% increments) of the prescription dose were calculated. Mean volumes of the heart and the LAD were lower (p<0.05) in 3D-DIBH for volumes receiving 5% to 80% of the prescription dose for the heart and 5% for the LAD. Mean dose to the LAD and heart were lower in 3D-DIBH (p≤0.01). Mean volumes of the total lung were lower in FB-IMRT for dose levels 20% to 75% (p<0.05), but mean dose was not different. Mean volumes of the right breast were not different for any dose; however, mean dose was lower for 3D-DIBH (p = 0.04). 3D-DIBH is an alternative approach to FB-IMRT that provides a clinically equivalent treatment for patients with left-sided breast cancer while sparing organs at risk with increased ease of implementation

    Breast cancer in men is a rare disease, accounting for approximately 1% of all breast cancer cases. Although the epidemiologic literature regarding female breast cancer is extensive, relatively little is known about the etiology of male breast cancer (MBC). This review is intended to summarize the existing body of evidence on genetic and epidemiologic risk factors for breast cancer in men. Overall, the epidemiology of MBC presents similarities with the epidemiology of female breast cancer. Major genetic factors associated with an increased risk of breast cancer for men include BRCA2 mutations, which are believed to account for the majority of inherited breast cancer in men, Klinefelter syndrome, and a positive family history. Suspected genetic factors include AR gene mutations, CYP17 polymorphism, Cowden syndrome, and CHEK2. Epidemiologic risk factors for MBC include disorders relating to hormonal imbalances, such as obesity, testicular disorders (e.g., cryptorchidism, mumps orchitis, and orchiectomy), and radiation exposure. Suspected epidemiologic risk factors include prostate cancer,prostate cancer treatment, gynecomastia, occupational exposures (e.g., electromagnetic fields, polycyclic aromatic hydrocarbons, and high temperatures), dietary factors (e.g., meat intake and fruit and vegetable consumption), and alcohol intake.

  12. Radiation as a cause of breast cancer

    International Nuclear Information System (INIS)

    The possible role of radiation as a factor in the causation of breast cancer was investigated. Some variables said to be associated with a high risk of breast cancer include genetic factors, pre-existing breast disease, artificial menopause, family history of breast cancer, failure to breast feed, older than usual age at time of first pregnancy, high socioeconomic status, specific blood groups, fatty diet, obesity, and hormonal imbalances. To this list we must add ionizing radiation as an additional and serious risk factor in the causation of breast cancer. Among the irradiated groups which have an increase in the incidence of cancer of the breast are: tuberculous women subjected to repeated fluoroscopy; women who received localized x-ray treatments for acute post-partum mastitis; atom-bomb survivors; other x-ray exposures involving the breast, including irradiation in children and in experimental animals; and women who were treated with x rays for acne or hirsuitism. The dose of radiation received by the survivors of the atom bomb who subsequently developed cancer of the breast ranged from 80 to 800 rads, the tuberculous women who were fluoroscoped received an estimated 50 to 6,000 rads, the women who were treated for mastitis probably were exposed to 30 to 700 rads, and the patients with acne received 100 to 6,000 rads. These imprecise estimates are compared with mammographic doses in the range of 10s of rads to the breast at each examination, an imprecise estimate depending on technique and equipment. However imprecise these estimates may be, it is apparent that younger women are more likely than older women to develop cancer from exposure to radiation. It is pointed out that the American Cancer Society advises that women under 35 years should have mammography only for medical indication, not for so-called screening

  14. Breast cancer therapies weighed

    International Nuclear Information System (INIS)

    Even as the National Institutes of Health came under fire last week for giving short shrift to women in the institute's basic and clinical research programs, the report of a recent NIH consensus conference points up the need for more research on how to treat early breast cancer. Although the experts were able to agree on the best surgical treatment for women with early breast cancer, they couldn't resolve the more controversial issue of whether the patients should subsequently receive systemic treatment - chemotherapy or hormone therapy - to prevent recurrence of their disease. The panel reaffirmed that the removal of the lump and nearby lymph nodes, followed by irradiation, is just as effective as a mastectomy. But then came the contentious question: should women with early breast cancer, especially those without detectable lymph node metastases, receive drug therapy to prevent recurrence of the disease? Currently, 70% of such cancers are successfully treated with surgery and radiation alone. For this reason, about 2 years ago, the National Cancer Institute issued a clinical alert saying that addition treatment with drugs or hormones is a credible therapeutic option worthy of careful attention for all early stage patients. This pronouncement engendered a storm of criticism. A consensus panel concluded that in cases where tumors are 1 centimeter or less in diameter and no lymph nodes are affected, the likelihood of recurrence is so small that the benefits of adjuvant therapy would be insignificant. But for the patients with larger tumors, the panel concluded that the decision is an individual one that depends on personal preferences and a variety of prognostic factors that can help to indicate whether a woman is at high risk of having a recurrence and should therefore have adjuvant therapy

  15. Effects of irradiation for cervical cancer on subsequent breast cancer

    International Nuclear Information System (INIS)

    Previous research suggests that cervical cancer patients have a lower risk of breast cancer than women in the general population. Possible explanations include opposing risk factors for cervical cancer and breast cancer, the effect of irradiation used to treat cervical cancer, or both. The purpose of this study was to explore the relationship between irradiation for cervical cancer and the subsequent development of breast cancer. There was no statistically significant relationship between radiation to the ovarian area and the risk of breast cancer in this study. However, the results were consistent with a 19% reduction in risk for women irradiated for cervical cancer when compared to nonirradiated women. In a dose-response analysis, there was a nonsignificant trend of decreased risk of breast cancer with increased radiation up to 1800 rad. There was no consistent pattern for higher doses. The trend, although nonsignificant, differed by age. Women <60 years of age at irradiation were generally at a lower risk of breast cancer than nonirradiated women. Women over 59 years were at an increased risk. There are some potentially important findings from this study which might influence medical care. These should be examined in the larger International Radiation Study

  17. Ten year results of a randomised trial comparing two conservative treatment strategies for small size breast cancer

    International Nuclear Information System (INIS)

    We report the 10-year results of a randomised clinical trial in which two different breast conservation treatment strategies were compared in women with small, non-metastatic primary breast cancer: quadrantectomy, axillary dissection and radiotherapy (QUART) versus tumorectomy and axillary dissection followed by external radiotherapy and a boost with 192Ir implantation (TART). No second surgery was given to women with affected surgical margins. Axillary node positive women received adjuvant medical therapy. From 1985-1987, this trial accrued 705 patients, 360 in the QUART and 345 in the TART arm. Crude cumulative incidence curves for intrabreast tumour recurrence (IBTR) and metastases as first events and mortality curves in each of the two treatment arms were computed. A crude cumulative incidence curve of IBTR as a second event (in women who had already had a local recurrence) was also computed. The two groups were compared in terms of hazard for IBTR, metastases or death occurrence by using Cox regression models, both with and without adjustment for patient age, tumour size, number of metastatic axillary nodes and histology. Possible interactions between the aforementioned prognostic factors and the type of surgery were also investigated. The two groups were well matched for baseline patient and tumour characteristics, the only exception being resection margins, which were more often positive in the TART group. At the Cox model, a significant difference between groups was detected for IBTR (P<0.0001), but not for distant metastases and overall survival. In particular, 5- and 10-year estimates of crude cumulative incidence of IBTR were 4.7 and 7.4% in the QUART group, and 11.6 and 18.6% in the TART group. The difference was not substantially affected by patient or disease characteristics. Likewise, the status of resection margins in women who underwent TART treatment did not significantly influence the risk of occurrence of IBTRs. Finally, the rate of second IBTR

  18. Genetic factors and breast cancer laterality

    International Nuclear Information System (INIS)

    Women are more likely to develop cancer in the left breast than the right. Such laterality may influence subsequent management, especially in elderly patients with heart disease who may require radiation therapy. The purpose of this study was to explore possible factors for such cancer laterality. In this work, clinical data for consecutive patients with histologically confirmed breast cancer were reviewed, with emphasis on clinical presentation and family history. Between 2005 and 2012, 687 patients with breast cancer were seen. Two women with incomplete data and eleven men were excluded. In total, 343 (50.9%) patients presented with left breast cancer, 311 (46.1%) with right breast cancer, and 20 (3.0%) with simultaneous bilateral malignancy. There were no significant differences between the three groups, especially in regards to clinical presentation and tumor characteristics. A total of 622 (92.3%) patients had unilateral primary, 20 (3.0%) had simultaneous bilateral, and 32 (4.7%) had metachronous primary breast cancer with subsequent contralateral breast cancer after 7.5–236 months. The worst 10-year survival was for bilateral simultaneous (18%) compared with unilateral (28%) and metachronous primaries (90%). There were no differences in survival in relation to breast cancer laterality, handedness, and presence or absence of a family history of cancer. There were significant similarities between patients and first-degree relatives in regards to breast cancer laterality, namely same breast (30/66, 45.5%), opposite breast (9/66, 13.6%), and bilateral cancer (27/66, 40.9, P=0.01163). This was more evident among patients and their sisters (17/32, 53.1%) or mothers (11/27, 40.7%, P=0.0689). There were also close similarities in relation to age at initial diagnosis of cancer for patients and their first-degree relatives for age differences of ≤5 years (48/166, 28.9%), 6–10 years (34/166, 20.5%), and >11 years (84/166, 50.6%, P=0.12065).

    Mammograms are one of the most widely used techniques for preliminary screening of breast cancers. There is great demand for early detection and diagnosis of breast cancer using mammograms. Texture based feature extraction techniques are widely used for mammographic image analysis. In specific, wavelets are a popular choice for texture analysis of these images. Though discrete wavelets have been used extensively for this purpose, spherical wavelets have rarely been used for Computer-Aided Diagnosis (CAD) of breast cancer using mammograms. In this work, a comparison of the performance between the features of Discrete Wavelet Transform (DWT) and Spherical Wavelet Transform (SWT) based on the classification results of normal, benign and malignant stage was studied. Classification was performed using Linear Discriminant Classifier (LDC), Quadratic Discriminant Classifier (QDC), Nearest Mean Classifier (NMC), Support Vector Machines (SVM) and Parzen Classifier (ParzenC). We have obtained a maximum classification accuracy of 81.73% for DWT and 88.80% for SWT features using SVM classifier. PMID:24000991

    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

    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...

  4. Scintigraphic diagnosis of breast cancer in highly selected patients with dense breast and silicon breast augmentation

    International Nuclear Information System (INIS)

    The comparable diagnostic accuracy of 99mTc-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 99mTc 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

    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

    Societal perceptions may factor into the high rates of nontreatment in patients with lung cancer. To determine whether bias exists toward lung cancer, a study using the Implicit Association Test method of inferring subconscious attitudes and stereotypes from participant reaction times to visual cues was initiated. Participants were primarily recruited from an online survey panel based on US census data. Explicit attitudes regarding lung and breast cancer were derived from participants' ratings (n = 1778) regarding what they thought patients experienced in terms of guilt, shame, and hope (descriptive statements) and from participants' opinions regarding whether patients ought to experience such feelings (normative statements). Participants' responses to descriptive and normative statements about lung cancer were compared with responses to statements about breast cancer. Analyses of responses revealed that the participants were more likely to agree with negative descriptive and normative statements about lung cancer than breast cancer (Plung cancer compared with breast cancer; mean response times in the lung cancer/negative conditions were significantly shorter than in the lung cancer/positive conditions (Pcaregivers, healthcare providers, and members of the general public had comparable levels of negative implicit attitudes toward lung cancer. These results show that lung cancer was stigmatized by patients, caregivers, healthcare professionals, and the general public. Further research is needed to investigate whether implicit and explicit attitudes and stereotypes affect patient care. PMID:26698307

  14. Breast cancers in elderly women

    International Nuclear Information System (INIS)

    Breast cancer is the most commonly diagnosed cancer and leading cause of cancer mortality in women worldwide. Nearly half of the global total of breast cancer cases occurs in patients > 65 years of age. Advanced age at the diagnosis of breast cancer is associated with more favorable tumor biology, as indicated by increased hormone sensitivity, attenuated HER- 2/neu overexpression, and lower grades and proliferative indices Elderly patients, however, are more likely to present with larger and more advanced tumors, and recent reports suggest that lymph node involvement increases with age. Elderly patients care less likely to be treated according to accepted treatment guidelines and under treatment can, as a consequence, have a strong negative impact on survival.Breast cancer in elderly patients represents a great social problem and is expected to remain one of the most common cancers in the next half century.

    Many cancer cells rely on aerobic glycolysis for energy production and targeting of this pathway is a potential strategy to inhibit cancer cell growth. In this study, inhibition of five glycolysis pathway molecules (GLUT1, HKII, PFKFB3, PDHK1 and LDH) using 9 inhibitors (Phloretin, Quercetin, STF31, WZB117, 3PO, 3-bromopyruvate, Dichloroacetate, Oxamic acid, NHI-1) was investigated in panels of breast and ovarian cancer cell line models. All compounds tested blocked glycolysis as indicated by increased extracellular glucose and decreased lactate production and also increased apoptosis. Sensitivity to several inhibitors correlated with the proliferation rate of the cell lines. Seven compounds had IC50 values that were associated with each other consistent with a shared mechanism of action. A synergistic interaction was revealed between STF31 and Oxamic acid when combined with the antidiabetic drug metformin. Sensitivity to glycolysis inhibition was also examined under a range of O2 levels (21% O2, 7% O2, 2% O2 and 0.5% O2) and greater resistance to the inhibitors was found at low oxygen conditions (7% O2, 2% O2 and 0.5% O2) relative to 21% O2 conditions. These results indicate growth of breast and ovarian cancer cell lines is dependent on all the targets examined in the glycolytic pathway with increased sensitivity to the inhibitors under normoxic conditions.

    Full Text Available Presented modern literature data on the features of the pathogenesis, course, clinical and morphological expression and tumor characteristics, parameters and nodal metastasis of hematogenous bilateral breast cancer. Highlight the results of domestic and foreign studies in recent years to determine the prognostic factors and recurrence of synchronous and metachronous bilateral breast cancer. It was revealed that the frequency of bilateral breast tumor lesions varies widely, ranging from 0.1 to 20%, with metachronous tumors recorded significantly higher (69.6% than the synchronous (22.7%. The probability of occurrence of metachronous breast cancer is higher in women with a family history, as well as if they have a gene mutation BRCA-1. Found that the most common histological type of breast tumor with bilateral lesions is invasive ductal. However, the incidence of invasive lobular cancer and non-invasive lobular cancer is slightly higher among synchronous bilateral cancer compared with unilateral disease. Studies have shown that in a double-sided synchronous breast cancer tumor, as a rule, has a lower degree of differentiation, and the higher the expression level of estrogen receptors and progesterone receptors. Relevance of the issue because the identification of patterns in the study of lymphatic and hematogenous features bilateral metastasis of mammary tumors provides a basis for speculation about the differences in the progression of neoplastic disease in these groups and is a cause for further detailed research in this area to identify and evaluate the prognosis and also the choice of tactics of such patients.

    Full Text Available Objectives: We compared outcomes in post-menopausal estrogen receptor-positive (ER+ breast cancer patients treated with neoadjuvant hormonal therapy (NAHT or neoadjuvant chemotherapy (NACT.Methods: We retrospectively identified post-menopausal women who received either NAHT or NACT for non-metastatic, non-inflammatory, ER+, Her2neu negative breast cancer from 2004 to 2011. We compared long-term rates of locoregional relapse free survival (LRFS, distant metastasis free survival (DMFS, and overall survival (OS using the Kaplan-Meier method. The Cox proportional hazards model was used to identify patient and disease factors significantly associated with these endpoints. Results: We identified 99 patients in our study, including 27 who received NAHT and 72 who received NACT. There were no differences in 4-year LRFS, DMFS, or OS between groups. On Cox proportional hazards modeling, the type of systemic therapy (NAHT vs. NACT was not associated with OS. However, patients with progesterone receptor (PR positive disease had a 92% lower risk of death compared to patients with PR negative disease.Conclusions: Our data suggest that outcomes are not adversely affected by NAHT in post-menopausal women with ER+ breast cancer. Therefore, NAHT is a viable and potentially less toxic option than NACT in appropriately selected patients. Furthermore, although PR negative disease appears to be associated with poor prognosis, intensification of systemic treatment with chemotherapy may not be associated with improvement of disease-related outcomes in this patient population.

    Background There is an association between postmenopausal tamoxifen therapy and endometrial pathologies. We investigated the usefulness of diagnostic hysteroscopy and transvaginal ultrasonography (TVS) and estimated whether diagnostic hysteroscopy improves detection of endometrial pathologies in postmenopausal breast cancer patients on tamoxifen. Methods Ninety-seven postmenopausal breast cancer patients who had been taking tamoxifen 20 mg/d for ≥6 months went through TVS, diagnostic hysteroscopy, and endometrial biopsy examinations. The presence of endometrial histopathologic features with abnormal TVS and diagnostic hysteroscopic findings were correlated. Results No endometrial cancer was found in any of the 97 patients. Fifty-three patients (54.6%) developed endometrial polyps as diagnosed histopathologically. Fifty-nine patients (60.8%) tested positive in TVS exams, of whom 43 had polyps, four had hyperplasia, and 12 atrophy. Thirty-eight patients (39.2%) tested negative in TVS exams, of whom 10had polyps, three hyperplasia, and 25 atrophy. TVS exams presented 63.6% specificity, 81.8% sensitivity, 72.9%positive-predictive value, and 73.7% negative-predictive value, whereas the corresponding values of diagnostic hysteroscopy were 100%, 98.1%, 100%, and 97.8% respectively. The correct ratio of hysteroscopy was significantly higher than that of TVS (P=0.000). Conclusions In postmenopausal breast cancer patients treated with tamoxifen, TVS alone is not sufficient for the detection of endometrial pathologies. Additional use of diagnostic hysteroscopy considerably improves the detection of polyps, thus significantly reducing the rate of false-negative findings of endometrial pathologies.

  4. A comparative study of the biologic and molecular basis of murine mammary carcinoma: a model for human breast cancer

    International Nuclear Information System (INIS)

    Tritiated-DNA complementary to mouse mammary tumor virus (MMTV) RNA was synthesized in an endogeneous reaction with MMTV particles. This DNA was used as a probe via molecular hybridization to detect MMTV-specific RNA in 'spontaneous' mammary tumors of several strains of mice, including the 'nonproducer' BALB/c mammary tumors. MMTV-specific RNA was also found in certain normal tissues (spleen, kidney, and epididymis) of a high-mammary-cancer strain (GR). Aging or treatment with nonviral carcinogens also induced the appearance of MMTV-specific RNA in certain normal tissues of the low-mammary-cancer strains, C57BL and BALB/c. The relationship of the presence of MMTV-specific RNA to the etiology and pathogenesis of murine mammary neoplasia and its potential application to human breast cancer are discussed

    Full Text Available Mitochondria play important roles in cellular energy metabolism, free radical generation, and apoptosis. Mitochondrial DNA has been proposed to be involved in carcinogenesis because of its high susceptibility to mutations and limited repair mechanisms in comparison to nuclear DNA. Breast cancer is the most frequent cancer type among women in the world and, although exhaustive research has been done on nuclear DNA changes, several studies describe a variety of mitochondrial DNA alterations present in breast cancer. In this review article, we to provide a summary of the mitochondrial genomic alterations reported in breast cancer and their functional consequences.

    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

  8. 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)

    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)

    Recent studies have demonstrated low regional recurrence rates in early-stage breast cancer omitting axillary lymph node dissection (ALND) in patients who have positive nodes in sentinel lymph node dissection (SLND). This finding has triggered an active discussion about the effect of radiotherapy within this approach. The purpose of this study was to analyze the dose distribution in the axilla in standard tangential radiotherapy (SRT) for breast cancer and the effects on normal tissue exposure when anatomic level I-III axillary lymph node areas are included in the tangential radiotherapy field configuration. We prospectively analyzed the dosimetric treatment plans from 51 consecutive women with early-stage breast cancer undergoing radiotherapy. We compared and analyzed the SRT and the defined radiotherapy (DRT) methods for each patient. The clinical target volume (CTV) of SRT included the breast tissue without specific contouring of lymph node areas, whereas the CTV of DRT included the level I-III lymph node areas. We evaluated the dose given in SRT covering the axillary lymph node areas of level I-III as contoured in DRT. The mean V{sub D95} {sub %} of the entire level I-III lymph node area in SRT was 50.28 % (range, 37.31-63.24 %), V{sub D45} {sub Gy} was 70.1 % (54.8-85.4 %), and V{sub D40} {sub Gy} was 83.5 % (72.3-94.8 %). A significant difference was observed between lung dose and heart toxicity in SRT vs. DRT. The V{sub 20} {sub Gy} and V{sub 30} {sub Gy} of the right and the left lung in DRT were significantly higher in DRT than in SRT (p < 0.001). The mean heart dose in SRT was significantly lower (3.93 vs. 4.72 Gy, p = 0.005). We demonstrated a relevant dose exposure of the axilla in SRT that should substantially reduce local recurrences. Furthermore, we demonstrated a significant increase in lung and heart exposure when including the axillary lymph nodes regions in the tangential radiotherapy field set-up. (orig.)

    Recently, energy- and intensity-modulated electron radiotherapy (MERT) has garnered a growing interest for the treatment of superficial targets. In this work, we carried out a comparative dosimetry study to evaluate MERT, photon beam intensity-modulated radiation therapy (IMRT) and conventional tangential photon beams for the treatment of breast cancer. A Monte Carlo based treatment planning system has been investigated, which consists of a set of software tools to perform accurate dose calculation, treatment optimization, leaf sequencing and plan analysis. We have compared breast treatment plans generated using this home-grown treatment optimization and dose calculation software for these treatment techniques. The MERT plans were planned with up to two gantry angles and four nominal energies (6, 9, 12 and 16 MeV). The tangential photon treatment plans were planned with 6 MV wedged photon beams. The IMRT plans were planned using both multiple-gantry 6 MV photon beams or two 6 MV tangential beams. Our results show that tangential IMRT can reduce the dose to the lung, heart and contralateral breast compared to conventional tangential wedged beams (up to 50% reduction in high dose volume or 5 Gy in the maximum dose). MERT can reduce the maximum dose to the lung by up to 20 Gy and to the heart by up to 35 Gy compared to conventional tangential wedged beams. Multiple beam angle IMRT can significantly reduce the maximum dose to the lung and heart (up to 20 Gy) but it induces low and medium doses to a large volume of normal tissues including lung, heart and contralateral breast. It is concluded that MERT has superior capabilities to achieve dose conformity both laterally and in the depth direction, which will be well suited for treating superficial targets such as breast cancer.

    Full Text Available Indigenous Māori women have a 60% higher breast cancer mortality rate compared with European women in New Zealand. We investigated differences in cancer biological characteristics and their impact on breast cancer mortality disparity between Māori and NZ European women.Data on 2849 women with primary invasive breast cancers diagnosed between 1999 and 2012 were extracted from the Waikato Breast Cancer Register. Differences in distribution of cancer biological characteristics between Māori and NZ European women were explored adjusting for age and socioeconomic deprivation in logistic regression models. Impacts of socioeconomic deprivation, stage and cancer biological characteristics on breast cancer mortality disparity between Māori and NZ European women were explored in Cox regression models.Compared with NZ European women (n=2304, Māori women (n=429 had significantly higher rates of advanced and higher grade cancers. Māori women also had non-significantly higher rates of ER/PR negative and HER-2 positive breast cancers. Higher odds of advanced stage and higher grade remained significant for Māori after adjusting for age and deprivation. Māori women had almost a 100% higher age and deprivation adjusted breast cancer mortality hazard compared with NZ European women (HR=1.98, 1.55-2.54. Advanced stage and lower proportion of screen detected cancer in Māori explained a greater portion of the excess breast cancer mortality (HR reduction from 1.98 to 1.38, while the additional contribution through biological differences were minimal (HR reduction from 1.38 to 1.35.More advanced cancer stage at diagnosis has the greatest impact while differences in biological characteristics appear to be a minor contributor for inequities in breast cancer mortality between Māori and NZ European women. Strategies aimed at reducing breast cancer mortality in Māori should focus on earlier diagnosis, which will likely have a greater impact on reducing breast

  16. Aluminium, antiperspirants and breast cancer.

    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.

  17. US findings of bilateral primary breast cancer: Retrospective study

    International Nuclear Information System (INIS)

    Background: For women with breast cancer, the contralateral breast is at high risk. The bilateral cancers may be synchronous or metachronous. If the bilateral breast cancers have similar ultrasonography (US) appearances, the US findings of the first breast cancer (index cancer) might lead to early detection of the contralateral cancer. The purpose of this study was to identify the US characteristics of bilateral breast cancer and to determine whether bilateral breast cancers have similar US appearances and whether the US findings for one breast cancer might be predictive of the contralateral breast cancer. Methods: We retrospectively reviewed the US manifestations of 58 patients with surgically proven bilateral primary breast cancer and compared the contralateral cancer with the index cancer by evaluation the margin, shape, inside echoes, posterior attenuation, calcification and color flow signals of 58 lesion pairs to investigate whether the bilateral breast cancers have similar US appearances. Results: Bilateral primary breast cancers were more located in upper outer quadrant, frequently spiculation, taller than wide shape, with irregular margin, heterogeneous internal echo and acoustic shadowing, containing microcalcification and abundant color flow signals. The most common US appearances were taller than wide shape (75.0%, 87/116), irregular margins (79.3%, 92/116) and heterogeneous internal echo (86.2%, 100/116). Of the total 58 lesion pairs, 18 (31.0%) pairs had similar US characteristics, whereas 40 (69.0%) pairs had different US characteristics. Conclusions: US signs of the index cancer do not indicate the most likely appearance of the second cancer in the contralateral breast. Evaluation of the contralateral cancer should be performed without regard for the US findings for the index 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

    Ornithine decarboxylase (ODC), the rate-limiting enzyme in polyamine biosynthesis that decarboxylates ornithine to putrescine, has become a promising target for cancer research. The aim of this study is to investigate the role of ODC in breast cancer. We detected expression of ODC in breast cancer tissues and four breast cancer cell lines, and transfected breast cancer cells with an adenoviral vector carrying antisense ODC (rAd-ODC/Ex3as) and examined their growth and migration.ODC was overexpressed in breast cancer tissues and cell lines compared with non-tumor tissues and normal breast epithelial celis,and there was a positive correlation between the level of ODC mRNA and the staging of tumors.The expression of ODC correlated with cyclin D1,a cell cycle protein,in synchronized breast cancer MDA-MB-231 cells.Gene transfection of rAd-ODC/Ex3as markedly down-regulated expression Of ODC and cyclin D1,resulting in suppression of proliferation and cell cycle arrest at G0-G1 phase,and the inhibifion of colony formation,an anchorage-independent growth pattern,and the migratory ability of MDA-MB-231 cells.rAd-ODC/Ex3as also markedly reduced the concentration of putrescine,but not spermidine or spermine,in MDA-MB-231 cells.The results suggested that the ODC gene might act as aprognostic factor for breast cancer and it could be a promising therapeutic target.

    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. Sin embargo, los estudios que se están realizando en países de mediano a bajo nivel de ingresos, con mayor variabilidad de ingesta de alimentos, comienzan a mostrar resultados interesantes.

    In the therapy of metastatic breast cancer MAP was used with different dosages and different forms of administration. Pharmacokinetics and pharmacodynamics were investigated. MAP plasma concentrations are dose dependent with great interindividual variation. The cortisol suppressive effect is dependent on plasma concentrations with only narrow interindividual variability. The oral administration of the crystal suspension is equivalent to the administration of tablets concerning plasma levels und endocrine effects. The therapy schedule for i.m. application used here leads to lower MAP plasma concentrations and correspondingly to a minor endocrine effect than in oral therapy. Tumor effective and cortisol suppressive plasma concentrations seem to have the same level. PMID:6215599

    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.

    Multispectral imaging (MSI) based on imaging and spectroscopy, as relatively novel to the field of histopathology, has been used in biomedical multidisciplinary researches. We analyzed and compared the utility of multispectral (MS) versus conventional red-green-blue (RGB) images for immunohistochemistry (IHC) staining to explore the advantages of MSI in clinical-pathological diagnosis. The MS images acquired of IHC-stained membranous marker human epidermal growth factor receptor 2 (HER2), cytoplasmic marker cytokeratin5/6 (CK5/6), and nuclear marker estrogen receptor (ER) have higher resolution, stronger contrast, and more accurate segmentation than the RGB images. The total signal optical density (OD) values for each biomarker were higher in MS images than in RGB images (all P  0.05). However, by quantifying MS images, the total signal OD values of HER2 positive expression were correlated with lymph node status and histological grades (P = 0.02 and 0.04). Additionally, the consistency test results indicated the inter-observer agreement was more robust in MS images for HER2 (inter-class correlation coefficient (ICC) = 0.95, r s = 0.94), CK5/6 (ICC = 0.90, r s = 0.88), and ER (ICC = 0.94, r s = 0.94) (all P < 0.001) than that in RGB images for HER2 (ICC = 0.91, r s = 0.89), CK5/6 (ICC = 0.85, r s = 0.84), and ER (ICC = 0.90, r s = 0.89) (all P < 0.001). Our results suggest that the application of MS images in quantitative IHC analysis could obtain higher accuracy, reliability, and more information of protein expression in relation to clinico-pathological characteristics versus conventional RGB images. It may become an optimal IHC digital imaging system used in quantitative pathology. PMID:26537585

    A prospective randomized study was carried out to evaluate the effectiveness of MPA in the treatment of breast cancer by comparing low dose (600 mg/day) with high dose (1,200 mg/day) of MPA. In 35 evaluable cases, the response rate to treatment was 40.0% (8/20) with low dose MPA and 26.7% (4/15) with high dose MPA. There was no significant difference between the two groups. The serum MPA concentration measured by high-performance liquid chromatography (HPLC) assay was 23.2 +/- 17.6 ng/ml in the low-dose group and 89.5 +/- 56.7 ng/ml in the high-dose group. Intrapatient variability in serum MPA concentration was relatively stable, but interpatient variability was large. No correlation was found between the response rate and serum MPA concentration. The above results indicate that a low dose of MPA (600 mg/day) is a useful treatment with high effectiveness and safety in advanced and recurrent breast cancer patients. Though no exact data on the optimal serum concentration could not be obtained, it was obvious that a successful response cannot be expected from a serum MPA concentration of less than 17 ng/ml, which was the average serum concentration in NC and PD patients of the low-dose group.

    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.

    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

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

    Full Text Available Background: Chemotherapy for breast cancer often deteriorates quality of life, augments fatigue, and induces neutropenia. Mistletoe preparations are frequently used by cancer patients in Central Europe. Physicians have reported better quality of life in breast cancer patients additionally treated with mistletoe preparations during chemotherapy. Mistletoe preparations also have immunostimulant properties and might therefore have protective effects against chemotherapy-induced neutropenia.Patients and Methods: We conducted a prospective randomized open label pilot study with 95 patients randomized into three groups. Two groups received Iscador® M special (IMS or a different mistletoe preparation, respectively, additionally to chemotherapy with six cycles of cyclophosphamide, adriamycin, and 5-fluoro-uracil (CAF. A control group received CAF with no additional therapy. Here we report the comparison IMS (n = 30 vs. control (n = 31. Quality of life including fatigue was assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30. Neutropenia was defined as neutrophil counts <1,000/µl and assessed at baseline and one day before each CAF cycle.Results: In the descriptive analysis all 15 scores of the EORTC-QLQ-C30 showed better quality of life in the IMS group compared to the control group. In 12 scores the differences were significant (p < 0.02 and nine scores showed a clinically relevant and significant difference of at least 5 points. Neutropenia occurred in 3/30 IMS patients and in 8/31 control patients (p = 0.182.Conclusions: This pilot study showed an improvement of quality of life by treating breast cancer patients with IMS additionally to CAF. CAF-induced neutropenia showed a trend to lower frequency in the IMS group.

    This study was conducted during the period from february 2004 to July 2004; with the objective of measuring the levels of estrogen (E2), carcinoembryonic antigen (CEA) and cancer antigen of breast (CA-15.3) so as to facilitate the early diagnosis of breast cancer and determine the involvement of these parameters as risk factors for breast cancer. Ninety blood samples were collected from Sudanese females, divided into two groups; control group and patient groups. The patients group was sixty Sudanese females visiting the Radio Isotope Center, Khartoum (RICK) and they were confirmed as breast cancer patient by histopathology. The levels of the above mentioned parameters were determined by using radioimmunoassay technique. The results showed that, no significant (p=0.05) difference between the levels of the estrogen in patients compared to the control, on the other hand there was non significant (p>0.05) elevation in CEA levels in the patients with breast cancer compared to the control. The level of CA15.3 was significantly (p<0.0001) higher in the breast cancer patients compared to the control.(Author)

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.

  18. Transillumination in breast cancer detection: screening failures and potential

    International Nuclear Information System (INIS)

    This prospective study of 1265 women referred to a multimodality breast diagnostic center compares the sensitivity for breast cancer detection of state-of-the-art transillumination light scanning and film-screen mammography. Of 33 biopsy-proven cancers, transillumination light scanning detected 58%, while mammography detected 97% of the cancers. Light scanning did detect 55% of the nonpalpable breast cancers, and 30% of those tumors smaller than 1 cm. Detection of breast cancer by light scanning was affected by breast size, but not architecture, and was directly related to tumor size. Although transillumination light scanning can detect some small curable breast cancers (smaller than 1 cm), it does not do so at a sensitivity adequate for screening

    Eribulin mesylate is a synthetic analog of halichondrin B (a polyether macrolide isolated from a marine sponge). It is a nontaxane microtubule dynamics inhibitor with a novel mechanism of action. It is the first drug that has demonstrated an improvement in overall survival as a single agent compared with the physician's choice of currently available treatments in locally advanced or metastatic breast cancer, previously treated with anthracyclines and taxanes. It has shown a good manageable tolerability profile. This drug has been approved by the US FDA and by the EMA for patients with locally advanced or metastatic breast cancer who have received at least two chemotherapeutic regimens for advanced/metastatic disease. Prior therapy should have included an anthracycline and a taxane in either the adjuvant or metastatic setting unless patients were not suitable for these treatments. The aim of this article is to describe the mechanism of action, pharmacokinetics, pharmacodynamics and the most relevant clinical trials in the development of this drug. PMID:24161305

Forty-one patients were randomized from September 2008 to July 2009 to receive either; (1 bevacizumab 5 mg/kg day 1 and day 15, carboplatin area under the curve (AUC-2 day 1, day 8, and day 15, and paclitaxel 60 mg/m2 day 1, day 8, and day 15 (arm-I; or (2 carboplatin AUC-5 day 1, docetaxel 75 mg/m2 day 1 (arm-II. The Kaplan–Meier method was used for estimating survival; log-rank test for comparing survival curves. The primary end point was PFS, and secondary end points were overall survival (OS and safety.Results: PFS was 10 months in arm I versus 10.2 months in arm II (P = 0.9. The OS rate was similar in both arms: 37.6 months for arm I versus 37.4 months for arm II (P = 0.92. The toxicity revealed higher incidence of hypertension and proteinuria in arm I; however, with higher incidence of grade III–IV neutropenia and neutropenic fever in arm II.

    Full Text Available Many oncological drugs that are being used in the adjuvant setting were first submitted for reimbursement in the metastatic stage, with differences in incremental cost-effectiveness ratios (ICERs in both settings having potential implications for reimbursement and pricing. The aim of this study is to identify a possible trend in the cost-effectiveness for the early/adjuvant and late/metastatic stages of oncological drugs through review and case study.We reviewed pairs of cost-effectiveness analyses of the same oncological drug in different stages for Scotland and the Netherlands. The case study in this report was directed at trastuzumab in the Dutch situation. Using a simplified Markov model, the cost-effectiveness in early and late stage of breast cancer was calculated and compared to the findings from the review.Comparable studies were found for cetuximab, bortezomib and bosutinib. Treatments in the late stage were found to be more expensive per QALY by a factor ranging from 1.5 to 12. The case study provided a similar result; late stage treatment was more expensive by a factor 10. Using, for example, a threshold of € 80,000/QALY, the early stage of cetuximab, bosutinib and trastuzumab are deemed cost-effective, while their compared late stage is lifted over the threshold and potentially considered not cost-effective.ICERs of oncological drugs used in different stages are more unfavourable in the late stage than in the early stage. Applying a reasonable threshold may result in early stage treatment being deemed cost-effective while late stage potentially not. Authorities should be aware of this when assessing oncological drugs and interpreting the corresponding ICERs, in the situation where oncological drugs are generally most submitted for reimbursement in the late stage initially.

    The rate of breast cancer screening for women of all ages in Japan is increasing. However, little is known about the biological differences between screen- and self-detected tumors. We used data from the Japanese Breast Cancer Registry (JBCR), a nationwide registry of newly diagnosed breast cancer cases in Japan, to investigate patients diagnosed between January 1, 2004 and December 31, 2011. We compared the clinicopathological features of tumors and assessed yearly trends regarding the proportion of screen-detected cases during the study period. We found that 31.8 % (65,358/205,544) of cancers were detected by screening. Asymptomatic tumors detected by screening (asymptomatic) were more likely to have favorable prognostic features than those that were self-detected (ductal carcinoma in situ [DCIS]: 19.8 versus 4.1 %, node-negative: 77.0 versus 61.6 %, and estrogen receptor-positive [ER+]: 82.0 versus 72.9 %, respectively). All these findings were statistically significant (p DCIS increased from 41.5 to 66.0 % and that of ER+ cancers increased from 23.2 to 39.7 %. This study demonstrated that low-risk tumors, including DCIS, ER+, and lower TNM stage, account for a substantial proportion of clinical screening-detected cancers. The differences in biological characteristics between screen- and self-detected cancers may account in part for the limited efficacy of breast cancer screening programs aimed at improving breast cancer mortality.

    Breast cancer is defined as a chronic disease.Increasing amounts of attention have been paid to the health management of breast cancer survivors. An important issue is how to find the most appropriate method of follow-up in order to detect long-term complications of treatment, local recurrence and distant metastasis and to administer appropriate treatment to the survivors with recurrence in a timely fashion. Different oncology organizations have published guidelines for following up breast cancer survivors. However, there are few articles on this issue in China. Using the published follow-up guidelines,we analyzed their main limitations and discussed the content,follow-up interval and economic benefits of following up breast cancer survivors in an effort to provide suggestions to physicians.Based on a large number of clinical trials, we discussed the role of physical examination, mammography, liver echograph, chest radiography, bone scan and so on. We evaluated the effects of the above factors on detection of distant disease, survival time,improvement in quality of life and time to diagnosis of recurrence.The results of follow-up carried out by oncologists and primary health care physicians were compared. We also analyzed the correlation factors for the cost of such follow-up. It appears that follow-up for breast cancer survivors can be carried out effectively by trained primary health care physicians. If anything unusual arises, the patients should be transferred to specialists.

    High-resolution array comparative genomic hybridisation (aCGH) analysis of DNA copy number aberrations (CNAs) was performed on breast carcinomas in premenopausal women from Western New York (WNY) and from Gomel, Belarus, an area exposed to fallout from the 1986 Chernobyl nuclear accident. Genomic DNA was isolated from 47 frozen tumour specimens from 42 patients and hybridised to arrays spotted with more than 3000 BAC clones. In all, 20 samples were from WNY and 27 were from Belarus. In total, 34 samples were primary tumours and 13 were lymph node metastases, including five matched pairs from Gomel. The average number of total CNAs per sample was 76 (range 35-134). We identified 152 CNAs (92 gains and 60 losses) occurring in more than 10% of the samples. The most common amplifications included gains at 8q13.2 (49%), at 1p21.1 (36%), and at 8q24.21 (36%). The most common deletions were at 1p36.22 (26%), at 17p13.2 (26%), and at 8p23.3 (23%). Belarussian tumours had more amplifications and fewer deletions than WNY breast cancers. HER2/neu negativity and younger age were also associated with a higher number of gains and fewer losses. In the five paired samples, we observed more discordant than concordant DNA changes. Unsupervised hierarchical cluster analysis revealed two distinct groups of tumours: one comprised predominantly of Belarussian carcinomas and the other largely consisting of WNY cases. In total, 50 CNAs occurred significantly more commonly in one cohort vs the other, and these included some candidate signature amplifications in the breast cancers in women exposed to significant radiation. In conclusion, our high-density aCGH study has revealed a large number of genetic aberrations in individual premenopausal breast cancer specimens, some of which had not been reported before. We identified a distinct CNA profile for carcinomas from a nuclear fallout area, suggesting a possible molecular fingerprint of radiation-associated breast cancer. PMID:16222315

    The prognostic value of tumor infiltrating lymphocytes in breast cancer has long been recognized by histopathologists. These observations were reaffirmed by recent immunohistochemistry and gene expression profiling studies that also revealed an association between greater chemotherapy sensitivity and extensive lymphocytic infiltration in early stage breast cancers treated with neoadjuvant chemotherapy. These results suggest that local anti-tumor immune response can at least partially control cancer growth and may mediate the antitumor effects of chemotherapy. However, until recently, there was no direct clinical evidence to demonstrate that enhancing anti-tumor immune response could lead to clinical benefit in breast cancer patients. The recent development of clinically effective immune checkpoint inhibitors made it possible to test the therapeutic impact of augmenting the local anti-tumor immune response. Two Phase I clinical trials using single agent anti-PD-1 (MK-3475, pembrolizumab) and anti-PD-L1 (MPDL3280A, atezolizumab) antibodies demonstrated close to 20% tumor response rates in heavily pretreated, metastatic, triple negative breast cancers. The most remarkable feature of the responses was their long duration. Several patients had disease control close to a year, or longer, which has not previously been seen with chemotherapy regimens in this patient population. A large number of clinical trials are currently underway with these and similar drugs in the neoadjuvant, adjuvant and metastatic settings to define the role of this new treatment modality in breast cancer.

    Full Text Available Breast cancer remains a major public health problem, being the second cause of cancer death in women. There is a marked tendency to restrict the extension of surgical gesture, which directly leads to two different attitudes: radical surgery and conservative surgery, to which, at least in our country, there are still some delays. Prospective and retrospective studies have shown that, in 20 years, conservative and radical therapy had about the same rate of survival and disease-free interval, at least for stage I and II breast cancer, the only real counterargument against conservative surgery being that, in principle, the higher rate of recurrence local constraint can be solved by postoperative radiotherapy. Finally, the survival rate is the main parameter of evaluation, assessing the effectiveness of the treatment in breast cancer, and in all its other forms.

  8. The role of lipolysis stimulated lipoprotein receptor in breast cancer and directing breast cancer cell behavior.

    Directory of Open Access Journals (Sweden)

    Denise K Reaves

    Full Text Available The claudin-low molecular subtype of breast cancer is of particular interest for clinically the majority of these tumors are poor prognosis, triple negative, invasive ductal carcinomas. Claudin-low tumors are characterized by cancer stem cell-like features and low expression of cell junction and adhesion proteins. Herein, we sought to define the role of lipolysis stimulated lipoprotein receptor (LSR in breast cancer and cancer cell behavior as LSR was recently correlated with tumor-initiating features. We show that LSR was expressed in epithelium, endothelium, and stromal cells within the healthy breast tissue, as well as in tumor epithelium. In primary breast tumor bioposies, LSR expression was significantly correlated with invasive ductal carcinomas compared to invasive lobular carcinomas, as well as ERα positive tumors and breast cancer cell lines. LSR levels were significantly reduced in claudin-low breast cancer cell lines and functional studies illustrated that re-introduction of LSR into a claudin-low cell line suppressed the EMT phenotype and reduced individual cell migration. However, our data suggest that LSR may promote collective cell migration. Re-introduction of LSR in claudin-low breast cancer cell lines reestablished tight junction protein expression and correlated with transepithelial electrical resistance, thereby reverting claudin-low lines to other intrinsic molecular subtypes. Moreover, overexpression of LSR altered gene expression of pathways involved in transformation and tumorigenesis as well as enhanced proliferation and survival in anchorage independent conditions, highlighting that reestablishment of LSR signaling promotes aggressive/tumor initiating cell behaviors. Collectively, these data highlight a direct role for LSR in driving aggressive breast cancer behavior.

    2016-01-01

    Breast cancer, one of the most common cancers in women, has various treatment modalities. Neoadjuvant therapy (NAT) has been used in many clinical trials because it is easy to evaluate the treatment response to therapeutic agents in a short time period; consequently, NAT is currently a standard treatment modality for large-sized and locally advanced breast cancers, and its use in early-stage breast cancer is becoming more common. Thus, chances to encounter breast tissue from patients treated with NAT is increasing. However, systems for handling and evaluating such specimens have not been established. Several evaluation systems emphasize a multidisciplinary approach to increase the accuracy of breast cancer assessment. Thus, detailed and systematic evaluation of clinical, radiologic, and pathologic findings is important. In this review, we compare the major problems of each evaluation system and discuss important points for handling and evaluating NAT-treated breast specimens. PMID:27068026

    Directory of Open Access Journals (Sweden)

    Full Text Available Abstract Background Cancer cell migration is fundamentally required for breast tumour invasion and metastasis. The insulin-like growth factor 1 tyrosine kinase receptor (IGF-1R and the chemokine G-protein coupled receptor, CXCR4 have been shown to play an important role in breast cancer metastasis. Our previous study has shown that IGF-1R can transactivate CXCR4 via a physical association in the human MDA-MB-231 metastatic breast cancer cell line and that this plays a key role in IGF-I-induced migration of these cells. In the present study we used pharmacological inhibition and RNAi to identify PI3Kγ as an important migration signalling molecule downstream of receptor transactivation in MDA-MB-231 cells. To identify PI3Kγ-regulated proteins upon transactivation of CXCR4 by IGF-I, we undertook a comparative proteomics approach using 2-D- Fluorescence Difference Gel Electrophoresis (DIGE and identified the proteins by mass spectrometry. Results These experiments identified eukaryotic elongation factor 2 (eEF2 as a novel downstream target of PI3Kγ after activation of the IGF-1R-CXCR4 heterodimer by IGF-I. Further analysis demonstrated that eEF2 is phosphorylated in MDA-MB-231 cells in response to IGF-I and that this is dependent on PI3Kγ activity. Conclusions Our data imply a novel role for PI3Kγ in facilitating cell migration by regulating phosphorylation of eEF2.

    To compare the average glandular dose (AGD) and diagnostic performance of mediolateral oblique (MLO) digital breast tomosynthesis (DBT) plus cranio-caudal (CC) digital mammography (DM) with two-view DM, and to evaluate the correlation of AGD with breast thickness and density. MLO and CC DM and DBT images of both breasts were obtained in 149 subjects. AGDs of DBT and DM per exposure were recorded, and their correlation with breast thickness and density were evaluated. Paired data of MLO DBT plus CC DM and two-view DM were reviewed for presence of malignancy in a jack-knife alternative free-response ROC (JAFROC) method. The AGDs of both DBT and DM, and differences in AGD between DBT and DM (ΔAGD), were correlated with breast thickness and density. The average JAFROC figure of merit (FOM) was significantly higher on the combined technique than two-view DM (P = 0.005). In dense breasts, the FOM and sensitivity of the combined technique was higher than that of two-view DM (P = 0.003) with small ΔAGD. MLO DBT plus CC DM provided higher diagnostic performance than two-view DM in dense breasts with a small increase in AGD. (orig.)

  17. Dermatologic radiotherapy and breast cancer

    International Nuclear Information System (INIS)

    This study was set up to provide quantitative data to evaluate unsubstantiated claims that improper dermatologic radiation techniques may cause breast cancer. A thin mylar window ionization rate meter placed at the location of the right breast of an Alderson-RANDO anthropomorphic phantom was used to measure direct and scatter radiation reaching the female breast during radiotherapy of the facial region (as given for acne). The results indicate that scatter doses are very small; they are influenced by radiation quality and the use or nonuse of a treatment cone. Quantitative risk estimates show that the very small risk of breast cancer induction can be reduced even further by the use of proper radiation protection measures. (orig.)

  1. Breast cancer screening in Canada: a review

    International Nuclear Information System (INIS)

    Organized screening for breast cancer in Canada began in 1988 and has been implemented in all provinces and 2 of the 3 territories. Quality initiatives are promoted through national guidelines which detail best practices in various areas, including achieving quality through a client-service approach, recruitment and capacity, retention, quality of mammography, reporting, communication of results, follow-up and diagnostic workup, and program evaluation; it also offers detailed guidelines for the pathological examination and reporting of breast specimens. The Canadian Breast Cancer Data Base is a national breast cancer screening surveillance system whose objective is to collect information from provincial-screening programs. These data are used to monitor and evaluate the performance of programs and allow comparison with national and international results. A series of standardized performance indicators and targets for the evaluation of performance and quality of organized breast cancer screening programs have been developed from the data base. Although health care is a provincial responsibility in Canada, the collective reporting and comparison of results both nationally and internationally is beneficial in evaluating and refining both screening programs and individual radiologist performance. The results of Canadian performance indicators compare favourably with those of other well-established international screening programs. There are variations in performance indicators across the provinces and territories, but these differences are not extreme. (author)

    Objective: to evaluate the comparative impact of magnetic resonance imaging and bone scintigraphy in bone metastases of breast cancer. Methods and patients: in 81 patients with histologically proven breast cancer magnetic resonance imaging of the axial skeleton and whole-body bone scintigraphy had been performed. Images were retrospectively reviewed and compared for detection of metastases, extent of metastatic disease and therapeutic implications according to the patients' records. Results: about 54/81 (67%) patients revealed bone metastases. In 7/54 (13%) patients with bone metastases, scintigraphy was false negative. In one patient a solitary sternal metastases was seen. In 26/53 [49%] patients with spinal metastases, magnetic resonance imaging showed more extensive disease. Local radiotherapy or surgery was indicated in ten patients with metastases not evident in bone scintigraphy, in 20 patients with positive results by both imaging modalities and in six patients with metastases of pelvis imaged by bone scintigraphy only. Conclusion: magnetic resonance imaging of the axial skeleton and pelvis appears superior for staging as only one patient had metastases merely outside the axial skeleton and local therapy was indicated even in spinal regions negative in bone scintigraphy.

    2010-01-01

    Cancer of breast has emerged as the leading site of cancer in most urban populations of India. For the year 2007, there have been an estimated 82,000 new cases of cancer Breast in India. It is rapidly replacing cancer of cervix as the most important leading site of cancer among women. The data collected over the years from five urban population based cancer registries namely Bangalore, Bhopal, Chennai, Delhi and Mumbai, under the network of National Cancer Registry Programme (NCRP) have shown a statistical rising trend in the incidence rate of breast cancer. In hospital-based cancer registries, cancer of the breast is the leading site of cancer in Mumbai and Thiruvananthapuram, second leading site in Bangalore, Dibrugarh and Chennai. Cancer of breast constitutes 14.3 to 30.0% of all cancers in women in these HBCRs. The report on 'Development of an Atlas of Cancer in India' showed that Chandigarh (39.5), North Goa (36.8), Aizawl (36.2) and Panchkula (34.6) had the higher microscopic incidence rates of breast cancer compared to that seen in Delhi PBCR that had the highest rate among all PBCRs.

    2014-01-01

    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.

  7. Comprehensive analysis of NuMA variation in breast cancer

    International Nuclear Information System (INIS)

    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. 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. 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. Our results do not support the role of NuMA variants as breast cancer susceptibility alleles

  8. Transcription profiles of non-immortalized breast cancer cell lines

    International Nuclear Information System (INIS)

    Searches for differentially expressed genes in tumours have made extensive use of array technology. Most samples have been obtained from tumour biopsies or from established tumour-derived cell lines. Here we compare cultures of non-immortalized breast cancer cells, normal non-immortalized breast cells and immortalized normal and breast cancer cells to identify which elements of a defined set of well-known cancer-related genes are differentially expressed. Cultures of cells from pleural effusions or ascitic fluids from breast cancer patients (MSSMs) were used in addition to commercially-available normal breast epithelial cells (HMECs), established breast cancer cell lines (T-est) and established normal breast cells (N-est). The Atlas Human Cancer 1.2 cDNA expression array was employed. The data obtained were analysed using widely-available statistical and clustering software and further validated through real-time PCR. According to Significance Analysis of Microarray (SAM) and AtlasImage software, 48 genes differed at least 2-fold in adjusted intensities between HMECs and MSSMs (p < 0.01). Some of these genes have already been directly linked with breast cancer, metastasis and malignant progression, whilst others encode receptors linked to signal transduction pathways or are otherwise related to cell proliferation. Fifty genes showed at least a 2.5-fold difference between MSSMs and T-est cells according to AtlasImage, 2-fold according to SAM. Most of these classified as genes related to metabolism and cell communication. The expression profiles of 1176 genes were determined in finite life-span cultures of metastatic breast cancer cells and of normal breast cells. Significant differences were detected between the finite life-span breast cancer cell cultures and the established breast cancer cell lines. These data suggest caution in extrapolating information from established lines for application to clinical cancer research

  10. Tumor-suppressor activity of RRIG1 in breast cancer

    International Nuclear Information System (INIS)

    Retinoid receptor-induced gene-1 (RRIG1) is a novel gene that has been lost in several types of human cancers. The aim of this study was to determine whether RRIG1 plays a role in breast cancer, such as in the suppression of breast cancer cell growth and invasion. Immunohistochemistry was used to detect RRIG1 expression in breast tissue specimens. Gene transfection was used to restore or knock down RRIG1 expression in breast cancer cell lines for analysis of cell viability, colony formation, and migration/invasion potential. Reverse-transcription polymerase chain reaction and western blot assays were used to detect the changes in gene expression. The RhoA activation assay was used to assess RRIG1-induced inhibition of RhoA activity. The immunohistochemical data showed that RRIG1 expression was reduced in breast cancer tissues compared with normal and atypical hyperplastic breast tissues. RRIG1 expression was inversely correlated with lymph node metastasis of breast cancer but was not associated with the status of hormone receptors, such as estrogen receptor, progesterone receptor, or HER2. Furthermore, restoration of RRIG1 expression inhibited proliferation, colony formation, migration, and invasion of breast cancer cells. Expression of RRIG1 also reduced phosphorylated Erk1/2 and Akt levels; c-Jun, MMP9, and Akt expressions; and RhoA activity. In contrast, knockdown of RRIG1 expression promoted breast cancer cell proliferation, colony formation, migration, and invasion potential. The data from the current study indicated that RRIG1 expression was reduced or lost in breast cancer and that restoration of RRIG1 expression suppressed breast cancer cell growth and invasion capacity. Future studies will determine the underlying molecular mechanisms and define RRIG1 as a tumor-suppressor gene in breast cancer

  11. Breast density and mode of detection in relation to breast cancer specific survival: a cohort study

    International Nuclear Information System (INIS)

    The aim of this study was to examine breast density in relation to breast cancer specific survival and to assess if this potential association was modified by mode of detection. An additional aim was to study whether the established association between mode of detection and survival is modified by breast density. The study included 619 cases from a prospective cohort, The Malmö Diet and Cancer Study. Breast density estimated qualitatively, was analyzed in relation to breast cancer death, in non-symptomatic and symptomatic women, using Cox regression calculating hazard ratios (HR) with 95% confidence intervals. Adjustments were made in several steps for; diagnostic age, tumour size, axillary lymph node involvement, grade, hormone receptor status, body mass index (baseline), diagnostic period, use of hormone replacement therapy at diagnosis and mode of detection. Detection mode in relation to survival was analyzed stratified for breast density. Differences in HR following different adjustments were analyzed by Freedmans%. After adjustment for age and other prognostic factors, women with dense, as compared to fatty breasts, had an increased risk of breast cancer death, HR 2.56:1.07-6.11, with a statistically significant trend over density categories, p = 0.04. In the stratified analysis, the effect was less pronounced in non-symptomatic women, HR 2.04:0.49-8.49 as compared to symptomatic, HR 3.40:1.06-10.90. In the unadjusted model, symptomatic women had a higher risk of breast cancer death, regardless of breast density. Analyzed by Freedmans%, age, tumour size, lymph nodes, grade, diagnostic period, ER and PgR explained 55.5% of the observed differences in mortality between non-symptomatic and symptomatic cases. Additional adjustment for breast density caused only a minor change. High breast density at diagnosis may be associated with decreased breast cancer survival. This association appears to be stronger in women with symptomatic cancers but breast density could

    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...

  14. A comparative study of methylene blue dye and methylene blue with radioactive tracer in breast cancer sentinel node mapping

    International Nuclear Information System (INIS)

    Sentinel lymph node (SLN) biopsy was performed in 72 women with primary breast cancer. During the SLN biopsy, blue dye was used in 18 patients (blue dye; B group), and methylene blue associated with radioactive tracer was used with rhenium colloid in 12 patients (R group) and with phytate in 42 patients (F group). The identification rate of SLNs was 83.3% in the B group, 91.7% in the R group, and 92.9% in the F group. The frequency of SLNs was higher in the B group than in the R or the F group. Back up lymph node dissection was performed in all cases following the identification of SLNs. The rate of accurate identification was 93.3% in the B group, 90.9% in the R group, and 92.3% in the F group. In conclusion, the identification rate was lower in the B group than in the R or the F group, suggesting that methylene blue associated with radioactive tracer using rhenium colloid or phytate may improve the reliability of SLN biopsy.

  4. Breast cancer epidemiology and risk factors

    International Nuclear Information System (INIS)

    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

    Highlights: • The addition of supplemental US to mammography depicted additional 5.0 cancers per 1000 postoperative women. • Positive biopsy rate of mammography-detected lesions was 66.7% (4 of 6) and that of US-detected lesions was 40.0% (6 of 15). • US can be helpful to detect mammographically occult breast cancer in the contralateral breast in women with previous history of cancer and dense breast. - Abstract: Objective: To determine whether supplemental screening ultrasound (US) to mammography could improve cancer detection rate of the contralateral breast in patients with a personal history of breast cancer and dense breasts. Materials and methods: During a one-year study period, 1314 screening patients with a personal history of breast cancer and dense breasts simultaneously underwent mammography and breast US. BI-RADS categories were given for mammography or US-detected lesions in the contralateral breast. The reference standard was histology and/or 1-year imaging follow-up, and the cancer rate according to BI-RADS categories and cancer detection rate and positive biopsy rate according to detection modality were analyzed. Results: Of 1314 patients, 84 patients (6.4%) were categorized as category 3 with one interval cancer and one cancer which was upgraded to category 4A after 6-month follow-up US (2.5% cancer rate, 95% CIs 1.5–9.1%). Fifteen patients (1.1%) had category 4A or 4B lesions in the contralateral breast. Four lesions were detected on mammography (two lesions were also visible on US) and 11 lesions were detected on US and 5 cancers were confirmed (33.3%, 95% CIs 15.0–58.5%). Six patients (0.5%) had category 4C lesions, 2 detected on mammography and 4 on US and 4 cancers were confirmed (66.7%, 95% CIs 29.6–90.8%). No lesions were categorized as category 5 in the contralateral breast. Cancer detection rate by mammography was 3.3 per 1000 patients and that by US was 5.0 per 1000 patients, therefore overall cancer detection rate by

    Full Text Available BACKGROUND: During the first two decades of the U.S. AIDS epidemic, and unlike some malignancies, breast cancer risk was significantly lower for women with human immunodeficiency virus (HIV infection compared to the general population. This deficit in HIV-associated breast cancer could not be attributed to differences in survival, immune deficiency, childbearing or other breast cancer risk factors. HIV infects mononuclear immune cells by binding to the CD4 molecule and to CCR5 or CXCR4 chemokine coreceptors. Neoplastic breast cells commonly express CXCR4 but not CCR5. In vitro, binding HIV envelope protein to CXCR4 has been shown to induce apoptosis of neoplastic breast cells. Based on these observations, we hypothesized that breast cancer risk would be lower among women with CXCR4-tropic HIV infection. METHODS AND FINDINGS: We conducted a breast cancer nested case-control study among women who participated in the WIHS and HERS HIV cohort studies with longitudinally collected risk factor data and plasma. Cases were HIV-infected women (mean age 46 years who had stored plasma collected within 24 months of breast cancer diagnosis and an HIV viral load≥500 copies/mL. Three HIV-infected control women, without breast cancer, were matched to each case based on age and plasma collection date. CXCR4-tropism was determined by a phenotypic tropism assay. Odds ratios (OR and 95% confidence intervals (CI for breast cancer were estimated by exact conditional logistic regression. Two (9% of 23 breast cancer cases had CXCR4-tropic HIV, compared to 19 (28% of 69 matched controls. Breast cancer risk was significantly and independently reduced with CXCR4 tropism (adjusted odds ratio, 0.10, 95% CI 0.002-0.84 and with menopause (adjusted odds ratio, 0.08, 95% CI 0.001-0.83. Adjustment for CD4+ cell count, HIV viral load, and use of antiretroviral therapy did not attenuate the association between infection with CXCR4-tropic HIV and breast cancer. CONCLUSIONS: Low

    Full Text Available Abstract Background Male breast cancer is a comparatively rare disease, and simultaneous bilateral male breast cancer is considered to be an extremely rare event. Risk factors are said to be genetic factors and hormonal abnormalities due to obesity or testicular diseases. Case presentation The patient was a 47-year-old Japanese male. His family had no history of female breast cancer. This patient also had hypospadias and hormonal examination indicated the presence of primary testicular potential hypogonadism, and these hormonal abnormalities seemed to be present since childhood or the fetal period. The bilateral breast cancer developed in this man at a comparatively young age, and histopathological studies of multiple sections showed that there was almost no normal epithelial cell in the ducts, while the ducts were almost completely filled with breast cancer cells. Conclusion It is thought that male breast cancer is caused by an imbalance between estrogen and testosterone. We cannot rule out the possibility that the breast cancer developed due to the effect of the slight elevation of estrogen over a long period of time, but the actual causative factors in this patient were unable to be definitively identified. In the future, we hope to further elucidate the causes of male breast cancer.

    Since adjuvant chemotherapy and hormonal therapy generally extend disease free survival in breast cancer rather than provide a cure, we have examined the current breast cancer paradigm. Heterogeneity is a fundamental characteristic of breast cancer tissue and a well recognized aspect of the disease. There are variations in natural history, histopathology, biochemistry and endocrinology, and molecular biology of cancer tissues and cells within the tissues. A variety of data indicate that growth kinetics are also variable, not only from tumor to tumor, but also during the natural history of an individual's tumor. To better understand kinetic heterogeneity, a stochastic numeric computer model of the natural history of breast cancer has been developed. To be consistent with inter- and intratumor kinetic heterogeneity and with late relapse, the model predicts that tumors grow in an irregular fashion with alternating periods of growth and periods of dormancy rather than the generally accepted modified exponential, or Gompertzian fasion. The prediction of irregular growth has been compared to data relevant to growth characteristics of human breast cancer. Much data support the concept of irregular kinetics and temporary dormancy rather than steady, Gompertzian growth of human breast cancer. Thus, in addition to drug resistance, kinetic heterogeneity may help explain the limited impact that traditional chemotherpeutic treatment has had on mortality from breast cancer. Although the mechanisms underlying irregular growth need to be better understood, non-Gompertzian growth kinetics indicates that there may be alternative approaches for breast cancer treatment.

    Full Text Available Length of survival of cancer patients is an important indicator for knowing the outcome of treatment in any study. Epidemiological features and biological profile of breast cancer appear to be different in developing countries as compared to Western countries. Knowing the factors that influence survival rates among women with breast cancer may help define early detection actions, and improve treatment and care proposals in all the areas of health. Therefore, this study aims to identify, the publications defining the factors influencing survival for women with breast cancer in India. PUBMED database was searched from January 1990 to April 2016, using the key words Breast cancer, breast cancer outcome and Survival and their corresponding Mesh terms were used in combination with Boolean operators like OR, AND. Five year overall survival rate of breast cancer in India ranged from 40-62%. The results from 16 publications showed that survival of breast cancer varies widely depending on number of factors like age, stage at diagnosis, marital status, educational level, hormonal status, clinical extent of disease and treatment. The publications that make up this review present contributing factors that affect the survival rate of women with breast cancer in India. This information on survival studies can pinpoint the lacunae in treatment modalities and can guide us to do basic and translational research so the preventive strategies can be implemented.

  15. A comparative dosimetric study for treating left-sided breast cancer for small breast size using five different radiotherapy techniques: conventional tangential field, filed-in-filed, Tangential-IMRT, Multi-beam IMRT and VMAT

    International Nuclear Information System (INIS)

    To compare the dosimetry for the left-sided breast cancer treatment using five different radiotherapy techniques. Twenty patients with left sided breast cancer were treated with conservative surgery followed by radiotherapy. They were planned using five different radiotherapy techniques, including: 1) conventional tangential wedge-based fields (TW); 2) field-in-field (FIF) technique; 3) tangential inverse planning intensity-modulated radiation therapy (T-IMRT); 4) multi-field IMRT (M-IMRT); and 5) volumetric modulated arc therapy (VMAT). The CTV, PTV and OARs including the heart, the regions of coronary artery (CA), the contralateral breast, the left and right lung were delineated. The PTV dose was prescribed 50Gy and V47.5≥95%. Same dose constraint was used for all five plans. The planned volumetric dose of PTV and PRV-OARs were compared and analyzed. Except VMAT (Average V47.5 was 94.72%±1.2%), all the other four plans were able to meet the V95% (V47.5) requirement. T-IMRT plan improved the PTV dose homogeneity index (HI) by 0.02 and 0.03 when compared to TW plan and VMAT plan, and decreased the V5, V10 and V20 of all PRV-OARs. However, the high dose volume (≥ 30Gy) of the PRV-OARs in T-IMRT plan had no statistically significant difference compared with the other two inverse plans. In all five plans, the dose volume of coronary artery area showed a strong correlation to the dose volume of the heart (the correlation coefficients were 0.993, 0.996, 1.000, 0.995 and 0.986 respectively). Compared to other techniques, the T-IMRT technology reduced radiation dose exposure to normal tissues and maintained reasonable target homogeneity, VMAT is not recommended for left-sided breast cancer treatment. In five techniques, the dose-volume histogram (DVH) of the heart can be used to predict the dose-volume histogram (DVH) of the coronary artery

    Full Text Available Purpose: Human papillomaviruses (HPV may have a role in some breast cancers. The purpose of this study is to fill important gaps in the evidence. These gaps are: (i confirmation of the presence of high risk for cancer HPVs in breast cancers, (ii evidence of HPV infections in benign breast tissues prior to the development of HPV positive breast cancer in the same patients, (iii evidence that HPVs are biologically active and not harmless passengers in breast cancer.Methods: RNA-seq data from The Cancer Genome Atlas (TCGA was used to identify HPV RNA sequences in breast cancers. We also conducted a retrospective cohort study based on polymerase chain reaction (PCR analyses to identify HPVs in archival specimens from Australian women with benign breast biopsies who later developed breast cancer. To assess whether HPVs in breast cancer were biologically active, the expression of the oncogenic protein HPV E7 was assessed by immunohistochemistry (IHC.Results: Thirty (3.5% low risk and 20 (2.3% high risk HPV types were identified in 855 breast cancers from the TCGA data base. The high risk types were HPV 18 (48%, HPV 113 (24%, HPV 16 (10%, HPV 52 (10%. Data from the PCR cohort study, indicated that HPV type 18 was the most common type identified in breast cancer specimens (55% of 40 breast cancer specimens followed by HPV 16 (13%. The same HPV type was identified in both the benign and subsequent breast cancer in 15 patients. HPV E7 proteins were identified in 72% of benign breast specimens and 59% of invasive breast cancer specimens.Conclusions: There were 4 observations of particular interest: (i confirmation by both NGS and PCR of the presence of high risk HPV gene sequences in breast cancers, (ii a correlation between high risk HPV in benign breast specimens and subsequent HPV positive breast cancer in the same patient, (iii HPVs in breast cancer are likely to be biologically active (as shown by transcription of HPV DNA to RNA plus the expression of

    Full Text Available Melissa C Southey,1 Zhi L Teo,1 Ingrid Winship2 1Genetic Epidemiology Laboratory, Department of Pathology, The University of Melbourne, Victoria, Australia; 2The Department of Medicine, The University of Melbourne, Victoria, Australia and The Royal Melbourne Hospital, Parkville, Victoria, Australia Abstract: For almost two decades, breast cancer clinical genetics has operated in an environment where a heritable cause of breast cancer susceptibility is identified in the vast minority of women seeking advice about their personal and/or family history of breast and/or ovarian cancer. A new wave of genetic information is upon us that promises to provide an explanation for the greater proportion of current missing heritability of breast cancer. Whilst researchers refine bioinformatic and analytic methodology necessary to interpret the new genetic data, attention needs to be paid to defining appropriate and coordinated pathways for the translation of this information so that it can be applied in clinical genetic services for the benefit of the majority of women who currently have no explanation for their breast cancer susceptibility. The search for additional breast cancer susceptibility genes remains a very active area of research. Exhausting the power of linkage studies that identified BRCA1 and BRCA2, the research community moved to candidate gene studies that led to the identification of ATM, BRIP1, CHEK2, and PALB2 as so-called "moderate-risk" breast cancer susceptibility genes. Mutations in these genes are rare and although early reports suggested that, on average, they are associated with moderate risks of breast cancer; population-based studies have demonstrated that at least some mutations in these genes are associated with breast cancer risks that are comparable to the average risk associated with BRCA2 mutations. The search for additional breast cancer susceptibility genes has now moved onto research platforms applying massively parallel

    Full Text Available Background: Clinical experiences have revealed that patients with breast cancer experience various sexual problems following their treatment. Breast cancer negatively impacts the sexual life of the afflicted couples, and as a traumatic event can influence women’s psychosexual functioning and intimate relationship. This review focuses on sexuality after breast cancer and on a growing need for bio-psycho-social guidelines for breast cancer treatment. Methods: This study aims to review the literature on management, psychological outcomes and sexual dysfunction in patients with breast cancer. Results: Although the benefits of the current treatment strategies are well established, many cancer survivors are at risk for developing psycho physiological symptoms including sexual dysfunction. Cancer and treatment-related factors can influence sexual functioning. We review current treatment -related side effects on sexual functioning such as desire, arousal and orgasm in breast cancer patients. Despite the impact of medical treatment on survival of patients with breast cancer, no satisfactory steps have been taken towards improving sexual functioning of these patients. Conclusion: Breast cancer affects many aspects of sexuality, including changes in physical functioning and in the perception of feminity. Sexual dysfunction following breast cancer should be diagnosed and managed as a systematic approach with multidisciplinary inputs. Healthcare professionals should assess the effects of medical and surgical treatment on the sexuality of breast cancer survivors.

    Background Many researches suggested that obesity increased the risk of breast cancer, but the mechanism was currently unknown. Adipocytokines might mediate the relationship. Our study was aimed to investigate the relationship between serum levels of resistin, adiponectin and leptin and the onset, invasion and metastasis of breast cancer.Methods Blood samples were collected from 80 newly diagnosed, histologically confirmed breast cancer patients and 50 age-matched healthy controls. Serum levels of resistin, adiponectin and leptin were determined by enzyme-linked immunosorbent assays (ELISA); fasting blood glucose (FBG), lipids, body mass index (BMI), and waist circumference (WC) were assayed simultaneously.Results Serum levels of adiponectin ((8.60±2.92) mg/L vs (10.37±2.81) mg/L, P=0.001) and HDL-c were significantly decreased in breast cancer patients in comparison to controls. Serum levels of resistin ((26.35±5.36) μg/L vs (23.32±4.75)μg/L, P=0.000), leptin ((1.35±0.42) μg/L vs (1.06±0.39) μg/L, P=0.003), FBG and triglyceride (TG) in breast cancer patients were increased in contrast to controls, respectively. However, we did not find the significant difference of the serum levels of resistin, adiponectin and leptin between premenopausal breast cancer patients and healthy controls (P=0.091, 0.109 and 0.084, respectively). The serum levels of resistin, adiponectin and leptin were significantly different between patients with lymph node metastasis (LNM) and those without LNM (P=0.001, 0.000 and 0.006, respectively).The stepwise regression analysis indicated that the tumor size had the close correlation with leptin (R2=0.414, P=0.000)and FBG (R2=0.602, P=0.000). Logistic regression analysis showed that reduced serum levels of adiponectin (OR:0.805;95%CI: 0.704-0.921; P=0.001), HDL (OR: 0.087; 95%CI: 0.011-0.691, P=0.021), elevated leptin (OR:2.235;95%CI:1.898-4.526; P=0.004) and resistin (OR: 1.335; 95%CI: 1.114-2.354; P=0.012) increased the risk for

    International Nuclear Information System (INIS)

    Background and purpose: The aim of the present paper is to update the practical guidelines for postoperative adjuvant radiotherapy of breast cancer published in 2007 by the breast cancer expert panel of the German Society for Radiooncology (Deutsche Gesellschaft fuer Radioonkologie, DEGRO). The present recommendations are based on a revision of the German interdisciplinary S-3 guidelines published in July 2012. Methods: A comprehensive survey of the literature concerning radiotherapy following breast conserving therapy (BCT) was performed using the search terms 'breast cancer', 'radiotherapy', and 'breast conserving therapy'. Data from lately published meta-analyses, recent randomized trials, and guidelines of international breast cancer societies, yielding new aspects compared to 2007, provided the basis for defining recommendations according to the criteria of evidence-based medicine. In addition to the more general statements of the DKG (Deutsche Krebsgesellschaft), this paper addresses indications, target definition, dosage, and technique of radiotherapy of the breast after conservative surgery for invasive breast cancer. Results: Among numerous reports on the effect of radiotherapy during BCT published since the last recommendations, the recent EBCTCG report builds the largest meta-analysis so far available. In a 15 year follow-up on 10,801 patients, whole breast irradiation (WBI) halves the average annual rate of disease recurrence (RR 0.52, 0.48-0.56) and reduces the annual breast cancer death rate by about one sixth (RR 0.82, 0.75-0.90), with a similar proportional, but different absolute benefit in prognostic subgroups (EBCTCG 2011). Furthermore, there is growing evidence that risk-adapted dose augmentation strategies to the tumor bed as well as the implementation of high precision RT techniques (e.g., intraoperative radiotherapy) contribute substantially to a further reduction of local relapse rates.

    Full Text Available Abstract Background Birth size, and particularly birth length, is positively associated with breast cancer risk in adulthood. The objective of this study was to examine whether birth size is associated with survival among breast cancer patients. Methods Information on birth size (weight, length and ponderal index (kg/length (m3 was collected from birth archives for 331 breast cancer patients who were diagnosed at two university hospitals in Norway (Bergen and Trondheim. The patients were followed from the time of diagnosis until death from breast cancer, death from another cause, or to the end of follow-up, and birth size was related to survival, using Cox regression analysis. Results Breast cancer patients with birth length ≥ 52 cm had nearly twice the risk of dying (hazard ratio, 1.92, 95% confidence interval, 1.09-3.41 from breast cancer compared to women with birth length less than 48 cm, after adjustment for place of birth and year of diagnosis. Similar analyses related to birth weight and ponderal index showed no clear association with breast cancer survival. Conclusions Poorer outcome of breast cancer patients with high birth length may reflect effects of factors that stimulate longitudinal growth and simultaneously increase the risk of metastases and fatal outcome. It is possible that the insulin-like growth factor (IGF system is involved in the underlying mechanisms.

  18. Mutation analysis of breast cancer gene BRCA among breast cancer Jordanian females

    International Nuclear Information System (INIS)

    To screen mutations of the tumor suppressor breast cancer susceptibility gene 1 (BRCA1) within 3 exons among Jordanian breast cancer females. A total of 135 Jordanian breast cancer females were genetically analyzed by denaturing gradient electrophoresis (DGGE) for mutation detection in 3 BRCA1 exons (2, 11 and 20) between 2000-2002 in Al-Basheer Hospital, Amman, Jordan. Of the studied patients 50 had a family history of breast cancer, 28 had a family history of cancer other than breast cancer, and 57 had no family history of any cancer. Five germline mutations were detected among breast cancer females with a family history of breast cancers (one in exon 2 and 4 mutations in exon 11). Another germline mutation (within exon 11) was detected among breast cancer females with family history of cancer other than breast cancer, and no mutation was detected among breast cancer females with no family history of any cancer or among normal control females. Screening mutations within exon 2, exon 11 and exon 20 showed that most screened mutations were within BRCA1 exon 11 among breast cancer Jordanian families with a family history of breast cancer.

  19. Measurement of tumour size with mammography, sonography and magnetic resonance imaging as compared to histological tumour size in primary breast cancer

    International Nuclear Information System (INIS)

    Tumour size in breast cancer influences therapeutic decisions. The purpose of this study was to evaluate sizing of primary breast cancer using mammography, sonography and magnetic resonance imaging (MRI) and thereby establish which imaging method most accurately corresponds with the size of the histological result. Data from 121 patients with primary breast cancer were analysed in a retrospective study. The results were divided into the groups “ductal carcinoma in situ (DCIS)”, invasive ductal carcinoma (IDC) + ductal carcinoma in situ (DCIS)”, “invasive ductal carcinoma (IDC)”, “invasive lobular carcinoma (ILC)” and “other tumours” (tubular, medullary, mucinous and papillary breast cancer). The largest tumour diameter was chosen as the sizing reference in each case. Bland-Altman analysis was used to determine to what extent the imaging tumour size correlated with the histopathological tumour sizes. Tumour size was found to be significantly underestimated with sonography, especially for the tumour groups IDC + DCIS, IDC and ILC. The greatest difference between sonographic sizing and actual histological tumour size was found with invasive lobular breast cancer. There was no significant difference between mammographic and histological sizing. MRI overestimated non-significantly the tumour size and is superior to the other imaging techniques in sizing of IDC + DCIS and ILC. The histological subtype should be included in imaging interpretation for planning surgery in order to estimate the histological tumour size as accurately as possible

  20. Estrogen and progesterone receptor levels in nonneoplastic breast epithelium of breast cancer cases versus benign breast biopsy controls

    International Nuclear Information System (INIS)

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

    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.

    2016-01-01

    Compared with other fields of medicine, there is hardly an area that has seen such fast development as the world of breast cancer. Indeed, the way we treat breast cancer has changed fundamentally over the past decades. Breast imaging has always been an integral part of this change, and it undergoes constant adjustment to new ways of thinking. This relates not only to the technical tools we use for diagnosing breast cancer but also to the way diagnostic information is used to guide treatment. There is a constant change of concepts for and attitudes toward breast cancer, and a constant flux of new ideas, new treatment approaches, and new insights into the molecular and biological behavior of this disease. Clinical breast radiologists and even more so, clinician scientists, interested in breast imaging need to keep abreast with this rapidly changing world. Diagnostic or treatment approaches that are considered useful today may be abandoned tomorrow. Approaches that seem irrelevant or far too extravagant today may prove clinically useful and adequate next year. Radiologists must constantly question what they do, and align their clinical aims and research objectives with the changing needs of contemporary breast oncology. Moreover, knowledge about the past helps better understand present debates and controversies. Accordingly, in this article, we provide an overview on the evolution of breast imaging and breast cancer treatment, describe current areas of research, and offer an outlook regarding the years to come.

    Full Text Available BACKGROUND AND METHODS: Formalin Fixed Paraffin Embedded (FFPE samples represent a valuable resource for cancer research. However, the discovery and development of new cancer biomarkers often requires fresh frozen (FF samples. Recently, the Whole Genome (WG DASL (cDNA-mediated Annealing, Selection, extension and Ligation assay was specifically developed to profile FFPE tissue. However, a thorough comparison of data generated from FFPE RNA and Fresh Frozen (FF RNA using this platform is lacking. To this end we profiled, in duplicate, 20 FFPE tissues and 20 matched FF tissues and evaluated the concordance of the DASL results from FFPE and matched FF material. METHODOLOGY AND PRINCIPAL FINDINGS: We show that after proper normalization, all FFPE and FF pairs exhibit a high level of similarity (Pearson correlation >0.7, significantly larger than the similarity between non-paired samples. Interestingly, the probes showing the highest correlation had a higher percentage G/C content and were enriched for cell cycle genes. Predictions of gene expression signatures developed on frozen material (Intrinsic subtype, Genomic Grade Index, 70 gene signature showed a high level of concordance between FFPE and FF matched pairs. Interestingly, predictions based on a 60 gene DASL list (best match with the 70 gene signature showed very high concordance with the MammaPrint® results. CONCLUSIONS AND SIGNIFICANCE: We demonstrate that data generated from FFPE material with the DASL assay, if properly processed, are comparable to data extracted from the FF counterpart. Specifically, gene expression profiles for a known set of prognostic genes for a specific disease are highly comparable between two conditions. This opens up the possibility of using both FFPE and FF material in gene expressions analyses, leading to a vast increase in the potential resources available for cancer research.

    Full Text Available A growing body of evidence suggests that breast cancer recurrence risk is linked to lifestyle behaviors. This study examined correlations between breast cancer recurrence, risk reduction beliefs, and related behaviors among African American breast cancer survivors (AA BCSs. Study participants included 191 AA BCSs, mean age = 56.3 years, who completed a lifestyle assessment tool. Most respondents believed that being overweight (52.7%, lack of physical activity (48.7%, and a high fat diet (63.2% are associated with breast cancer recurrence. Over 65% considered themselves overweight; one third (33.5% agreed that losing weight could prevent recurrence, 33.0% disagreed, while the remaining 33.5% did not know; and nearly half (47.9% believed that recurrence could be prevented by increasing physical activity. Almost 90% survivors with BMI < 25 Kg/M2 reported no recurrence compared to 75.7% with BMI ≥ 25 Kg/M2 (p = 0.06; nearly all of the women (99.2% answered “yes” to seeking professional help to lose weight, 79.7% of which were recurrence-free (p = 0.05. These results provide information about AA BCSs’ beliefs and behaviors protective against breast cancer recurrence. Additional research is warranted to determine the effectiveness of educational interventions for AA BCSs that promote consumption of a healthy diet and engaging in regular physical activity.

    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.

  12. Breast Cancer Susceptibility Gene1 (BRCA1

    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.

    2013-01-01

    For almost two decades, breast cancer clinical genetics has operated in an environment where a heritable cause of breast cancer susceptibility is identified in the vast minority of women seeking advice about their personal and/or family history of breast and/or ovarian cancer. A new wave of genetic information is upon us that promises to provide an explanation for the greater proportion of current missing heritability of breast cancer. Whilst researchers refine bioinformatic and analytic methodology necessary to interpret the new genetic data, attention needs to be paid to defining appropriate and coordinated pathways for the translation of this information so that it can be applied in clinical genetic services for the benefit of the majority of women who currently have no explanation for their breast cancer susceptibility. The search for additional breast cancer susceptibility genes remains a very active area of research. Exhausting the power of linkage studies that identified BRCA1 and BRCA2, the research community moved to candidate gene studies that led to the identification of ATM, BRIP1, CHEK2, and PALB2 as so-called "moderate-risk" breast cancer susceptibility genes. Mutations in these genes are rare and although early reports suggested that, on average, they are associated with moderate risks of breast cancer; population-based studies have demonstrated that at least some mutations in these genes are associated with breast cancer risks that are comparable to the average risk associated with BRCA2 mutations. The search for additional breast cancer susceptibility genes has now moved onto research platforms applying massively parallel sequencing capable of sequencing whole human exomes and genomes in single instrument runs. These programs are identifying a large number of additional putative breast cancer susceptibility genes, many of which are currently undergoing validation. It is highly anticipated that the remaining missing heritability of breast cancer

  16. Population screening for breast cancer in the European Community

    International Nuclear Information System (INIS)

    Although our understanding of the causes of breast cancer is increasing, it is as yet not possible to recommend measures to decrease its occurrence. Therefore we have to resort to a substitute called secondary prevention which aims at preventing the occurrence of metastatic breast cancer and death by detecting the primary cancer in the breast at an earlier point in its natural history. The question whether this can be achieved can only be answered by scientific study. Such studies are being called: population-based screening programmes. Screening requires one or more tests by which one can partition a population in those who probably have a cancer and those who have not. Since an early breast cancer does not produce symptoms like pain the test has to be some sort of objective assessment. In the field of detecting breast cancer we have been greatly helped by the development of a radiologic technique called mammography. Mammography basically is not an easy technique since there is little contrast between structures in the breast compared with e.g. bone. The quality of mammograms, therefore, was not very high in the pioneering era during the nineteen-fifties and -sixties. This presentation discusses a move of a few doctors in New York city: a radiologist, a surgeon and epidemiologist, to design a scientific study which could answer the question whether mammography, added to a standard clinical examination of the breast would decrease mortality from breast cancer

    2006-01-01

    Objective: To investigate the molecular etiology of breast cancer by way of studying the differential expression and initial function of the related genes in the occurrence and development of breast cancer. Methods: Two hundred and eighty-eight human tumor related genes were chosen for preparation of the oligochips probe. mRNA was extracted from 16 breast cancer tissues and the corresponding normal breast tissues, and cDNA probe was prepared through reverse-transcription and hybridized with the gene chip. A laser focused fluorescent scanner was used to scan the chip. The different gene expressions were thereafter automatically compared and analyzed between the two sample groups. Cy3/Cy5>3.5 meant significant up-regulation. Cy3/Cy5<0.25 meant significant down-regulation. Results: The comparison between the breast cancer tissues and their corresponding normal tissues showed that 84 genes had differential expression in the Chip. Among the differently expressed genes, there were 4 genes with significant down-regulation and 6 with significant up-regulation. Compared with normal breast tissues, differentially expressed genes did partially exist in the breast cancer tissues. Conclusion: Changes in multi-gene expression regulations take place during the occurrence and development of breast cancer; and the research on related genes can help understanding the mechanism of tumor occurrence.

    International Nuclear Information System (INIS)

    BACH1 (BRCA1-associated C-terminal helicase 1; also known as BRCA1-interacting protein 1, BRIP1) is a helicase protein that interacts in vivo with BRCA1, the protein product of one of the major genes for hereditary predisposition to breast cancer. Previously, two BACH1 germ line missense mutations have been identified in early-onset breast cancer patients with and without family history of breast and ovarian cancer. In this study, we aimed to evaluate whether there are BACH1 genetic variants that contribute to breast cancer risk in Finland. The BACH1 gene was screened for germ line alterations among probands from 43 Finnish BRCA1/2 negative breast cancer families. Recently, one of the observed common variants, Ser-allele of the Ser919Pro polymorphism, was suggested to associate with an increased breast cancer risk, and was here evaluated in an independent, large series of 888 unselected breast cancer patients and in 736 healthy controls. Six BACH1 germ line alterations were observed in the mutation analysis, but none of these were found to associate with the cancer phenotype. The Val193Ile variant that was seen in only one family was further screened in an independent series of 346 familial breast cancer cases and 183 healthy controls, but no additional carriers were observed. Individuals with the BACH1 Ser919-allele were not found to have an increased breast cancer risk when the Pro/Ser heterozygotes (OR 0.90; 95% CI 0.70–1.16; p = 0.427) or Ser/Ser homozygotes (OR 1.02; 95% CI 0.76–1.35; p = 0.91) were compared to Pro/Pro homozygotes, and there was no association of the variant with any breast tumor characteristics, age at cancer diagnosis, family history of cancer, or survival. Our results suggest that the BACH1 Ser919 is not a breast cancer predisposition allele in the Finnish study population. Together with previous studies, our results also indicate that although some rare germ line variants in BACH1 may contribute to breast cancer development, the

    Case Study Amy is a 44-year-old woman with severe autism. She lives with her sister Susan, who is her caregiver and guardian. Amy is ambulatory and able to dress and feed herself. She is a healthy individual with no other significant comorbidities. She walks daily and enjoys her sister's company. Amy's life expectancy is greater than 10 years. However, she is difficult to care for medically, as she will not allow a physical examination and strikes out when strangers try to touch her. She is nonverbal and unable to participate in decision-making. INITIAL DIAGNOSIS Amy has a history of breast cancer diagnosed 2 years ago, originally presenting as a stage I lesion (T2N0) that was palpated by her caregiver while bathing. She underwent right simple mastectomy with sentinel lymph node resection. Susan recalls that the mastectomy was a very challenging ordeal, as Amy kept pulling out IV lines, drains, and dressings. Susan felt that Amy withdrew from her after the procedure as she most likely associated Susan with the cause of the pain, making her role as caregiver more difficult. Pathology confirmed an invasive ductal carcinoma, moderately differentiated, 2.4 cm, estrogen/progesterone receptor negative, HER2/neu negative, with negative surgical margins. Two right axillary sentinel lymph nodes were negative for disease. The standard of care for a patient with these tumor features is surgery plus adjuvant chemotherapy (National Comprehensive Cancer Network [NCCN], 2012). According to the Adjuvant Online! database (2012), Amy's risk for relapse was approximately 40% without adjuvant treatment; her risk for mortality was approximately 29%. After meeting with a medical oncologist, Amy did not receive adjuvant chemotherapy. According to Susan, she was not offered the choice, and the decision was not explained to them. She was simply told that it was not necessary. Aside from pathology, previous records were unavailable for review. Medical assessment of Amy's level of autism

    The mammalian transcriptome has recently been revealed to encompass a large number of noncoding RNAs (ncRNAs) that play a variety of important regulatory roles in gene expression and other biological processes. MicroRNAs (miRNAs), the best studied of the short noncoding RNAs (sncRNAs), have been extensively characterized with regard to their biogenesis, function and importance in tumorigenesis. Another class of sncRNAs called piwi-interacting RNAs (piRNAs) has also gained attention recently in cancer research owing to their critical role in stem cell regulation. Long noncoding RNAs (lncRNAs) of >200 nucleotides in length have recently emerged as key regulators of developmental processes, including mammary gland development. lncRNA dysregulation has also been implicated in the development of various cancers, including breast cancer. In this review, we describe and discuss the roles of sncRNAs (including miRNAs and piRNAs) and lncRNAs in the initiation and progression of breast tumorigenesis, with a focus on outlining the molecular mechanisms of oncogenic and tumor-suppressor ncRNAs. Moreover, the current and potential future applications of ncRNAs to clinical breast cancer research are also discussed, with an emphasis on ncRNA-based diagnosis, prognosis and future therapeutics.

    The aim of the study was to prospectively compare the diagnostic value of whole-body diffusion-weighted imaging (DWI) and FDG PET/CT for breast cancer (BC) staging. Twenty BC patients underwent whole-body FDG PET/CT and 1.5-T DWI. Lesions with qualitatively elevated signal intensity on DW images (b = 800 s/mm{sup 2}) were rated as suspicious for tumour and mapped to individual lesions and different compartments (overall 552 lesions). The apparent diffusion coefficient (ADC) value was determined for quantitative evaluation. Histopathology, MRI findings, bone scan findings, concordant findings between FDG PET/CT and DWI, CT follow-up scans and plausibility served as the standards of reference defining malignancy. According to the standards of reference, breasts harboured malignancy in 11, regional lymph nodes in 4, M1 lymph nodes in 3, bone in 7, lung in 2, liver in 3 and other tissues in 3 patients. On a compartment basis, the sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) for the detection of malignancies were 94, 99, 98, 97 and 98% for FDG PET/CT and 91, 72, 76, 50 and 96% for DWI, respectively. Of the lesions seen on DWI only, 348 (82%) turned out to be false-positive compared to 23 (11%) on FDG PET/CT. The average lesion ADC was 820 {+-} 300 with true-positive lesions having 929 {+-} 252 vs 713 {+-} 305 in false-positive lesions (p < 0.0001). Based on these initial data DWI seems to be a sensitive but unspecific modality for the detection of locoregional or metastatic BC disease. There was no possibility to quantitatively distinguish lesions using ADC. DWI alone may not be recommended as a whole-body staging alternative to FDG PET(/CT). Further studies are necessary addressing the question of whether full-body MRI including DWI may become an alternative to FDG PET/CT for whole-body breast cancer staging. (orig.)

    Objective: The aim of this study was to evaluate the capability of dynamic contrast enhanced MR-mammography (MRM) for the interpretation of axillary lymph nodes (LNs) in patients with breast cancer. Material and methods: 25 patients with breast cancer preoperatively underwent both FDG positron emission computed tomography (PET-CT) and dynamic contrast enhanced MRM. The maximum signal increase (SI{sub max}) and curve shape (types I–III) of contrast enhanced LNs ≥0.5 cm (short-axis) were analyzed in MRM and correlated to the maximum standard uptake value (SUV{sub max}) of FDG PET-CT. 29 healthy women with MRM served as control group. Enhancement kinetics of all malignant LNs were compared to LN findings of the healthy control group. Results: Overall 33 contrast enhanced LNs on preoperative MRM had a corresponding FDG uptake on PET-CT. 30 of the PET positive LNs were classified as surely malignant (mean SUV{sub max} 7.3 (±5.4)). The mean SI{sub max} of these LNs was not significantly different to the control group (222% vs 197%), but malignant LNs had a significantly higher rate of type III curves with rapid washout (93% vs 66%, p = 0.008). Conclusion: The maximum signal increase is not capable of differentiating malignant from benign axillary LNs. However, since malignant LNs showed a higher frequency of rapid washout curves (type III curves) on corresponding MRM future studies should concentrate on the analysis of this parameter. In clinical routine the curve shape still should be taken with care as there is a high overlap with benign LNs.

    Breast cancer is the most common cancer and the second most common cause of death from cancer in women.The aim of this studywas to determine which is more accurate imaging test mammography or ultrasound for diagnosis of breast cancer based on the women's age and breast density. We examined 546 patients with breast symptoms, by clinical breast examination, mammography and ultrasound. A total of 546 breast lesions were examined by histopathology analyses. Histopathology results revealed the presence of 259 invasive cancers, and 287 benign lesions. Sensitivity varied significantly with age and breast density. In the 259 women who had both tests, ultrasound had a higher sensitivity than mammography in women younger than 45 years, whereas mammography had a higher sensitivity than ultrasound in women older than 60 years. The sensitivity according to age was 52,1% for mammography and 72,6% for ultrasound. The specificity according to age was 88, 5% for ultrasound and 73, 9% for mammography. Comparing the sensitivity of mammography and ultrasound according to the breast density indicates that mammographic sensitivity was 82,2% among women with predominantly fatty breast, but 23.7% in women with heterogeneous dense breasts, with the increase of fibro glandular density the level of sensitivity with mammography decreases, while ultrasonographic sensitivity was 71,1% among women with predominantly fatty breast and 57,0% for heterogeneous dense breasts. Our data indicate that sensitivity and specificity of ultrasound was statistically significantly greater than mammography in patients with breast symptoms for the detection of breast cancer and benign lesions particularly in dense breast and in young women.

    Diet may play a role in both promoting and inhibiting human breast cancer development. In this review, nutritional risk factors such as consumption of dietary fat, meat, fiber, and alcohol, and intake of phytoestrogen, vitamin D, iron, and folate associated with breast cancer are reviewed. These nutritional factors have a variety of associations with breast cancer risk. Type of fat consumed has different effects on risk of breast cancer: consumption of meat is associated with heterocyclic amine (HCA) exposure; different types of plant fiber have various effects on breast cancer risk; alcohol consumption may increase the risk of breast cancer by producing acetaldehyde and reactive oxygen species (ROS); intake of phytoestrogen may reduce risk of breast cancer through genomic and non-genomic action; vitamin D can reduce the risk of breast cancer by inhibiting the process of cancer invasion and metastasis; intake of dietary iron may lead to oxidative stress, DNA damage, and lipid peroxidation; and lower intake of folate may be linked to a higher risk of breast cancer.

  20. Clinicopathological significance of PTPN12 expression in human breast cancer

    International Nuclear Information System (INIS)

    Protein tyrosine phosphatase non-receptor type 12 (PTPN12) is a recently identified tumor suppressor gene (TSG) that is frequently compromised in human triple-negative breast cancer. In the present study, we investigated the expression of PTPN12 protein by patients with breast cancer in a Chinese population and the relationship between PTPN12 expression levels and patient clinicopathological features and prognosis. Additionally, we explored the underlying down-regulation mechanism from the perspective of an epigenetic alteration. We examined PTPN12 mRNA expression in five breast cancer cell lines using semi-quantitative reverse-transcription PCR, and detected PTPN12 protein expression using immunohistochemistry in 150 primary invasive breast cancer cases and paired adjacent non-tumor tissues. Methylation-specific PCR was performed to analyze the promoter CpG island methylation status of PTPN12. PTPN12 was significantly down-regulated in breast cancer cases (48/150) compared to adjacent noncancerous tissues (17/150; P < 0.05). Furthermore, low expression of PTPN12 showed a significant positive correlation with tumor size (P = 0.047), lymph node metastasis (P = 0.001), distant metastasis (P = 0.009), histological grade (P = 0.012), and survival time (P = 0.019). Additionally, promoter CpG island hypermethylation occurs more frequently in breast cancer cases and breast cancer cell lines with low PTPN12 expression. Our findings suggest that PTPN12 is potentially a methylation-silenced TSG for breast cancer that may play an important role in breast carcinogenesis and could potentially serve as an independent prognostic factor for invasive breast cancer patients

    The F box protein Skp2 is oncogenic. Skp2 and Skp2B, an isoform of Skp2 are overexpressed in breast cancer. However, little is known regarding the mechanism by which Skp2B promotes the occurrence and development of breast cancer. Here, we determined the expression and clinical outcomes of Skp2 in breast cancer samples and cell lines using breast cancer database, and investigated the role of Skp2 and Skp2B in breast cancer cell growth, apoptosis and cell cycle arrest. We obtained Skp2 is significantly overexpressed in breast cancer samples and cell lines, and high Skp2 expression positively correlated with poor prognosis of breast cancer. Both Skp2 and Skp2B could promote breast cancer cell proliferation, inhibit cell apoptosis, change the cell cycle distribution and induce the increased S phase cells and therefore induce cell proliferation in breast cancer cells. Moreover, the 2 isoforms could both suppress PIG3 expression via independent pathways in the breast cancer cells. Skp2 suppressed p53 and inhibited PIG3-induced apoptosis, while Skp2B attenuated the function of PIG3 by inhibiting PHB. Our results indicate that Skp2 and Skp2B induce breast cancer cell development and progression, making Skp2 and Skp2B potential molecular targets for breast cancer therapy. PMID:27111245

    Women constitute the majority of the aging United States (US) population, and this has substantial implications on cancer population patterns and management practices. Breast cancer is the most common women's malignancy, while ovarian cancer is the most fatal gynecological malignancy in the US. In this review, we focus on these subsets of women's cancers, seen more commonly in postmenopausal and elderly women. In order to systematically investigate the complexity of cancer progression and response to treatment in breast and ovarian malignancies, we assert that integrated mathematical modeling frameworks viewed from a systems biology perspective are needed. Such integrated frameworks could offer innovative contributions to the clinical women's cancers community, as answers to clinical questions cannot always be reached with contemporary clinical and experimental tools. Here, we recapitulate clinically known data regarding the progression and treatment of the breast and ovarian cancers. We compare and contrast the two malignancies whenever possible in order to emphasize areas where substantial contributions could be made by clinically inspired and validated mathematical modeling. We show how current paradigms in the mathematical oncology community focusing on the two malignancies do not make comprehensive use of, nor substantially reflect existing clinical data, and we highlight the modeling areas in most critical need of clinical data integration. We emphasize that the primary goal of any mathematical study of women's cancers should be to address clinically relevant questions.

    Abstract Aims: Vorinostat (suberoylanilide hydroxamic acid; SAHA) is a histone deacetylase inhibitor (HDACi) approved in the clinics for the treatment of T-cell lymphoma and with the potential to be effective also in breast cancer. We investigated the responsiveness to SAHA in human breast primary tumors and cancer cell lines. Results: We observed a differential response to drug treatment in both human breast primary tumors and cancer cell lines. Gene expression analysis of the breast cancer cell lines revealed that genes involved in cell adhesion and redox pathways, especially glutathione metabolism, were differentially expressed in the cell lines resistant to SAHA compared with the sensitive ones, indicating their possible association with drug resistance mechanisms. Notably, such an association was also observed in breast primary tumors. Indeed, addition of buthionine sulfoximine (BSO), a compound capable of depleting cellular glutathione, significantly enhanced the cytotoxicity of SAHA in both breast cancer cell lines and primary breast tumors. Innovation: We identify and validate transcriptional differences in genes involved in redox pathways, which include potential predictive markers of sensitivity to SAHA. Conclusion: In breast cancer, it could be relevant to evaluate the expression of antioxidant genes that may favor tumor resistance as a factor to consider for potential clinical application and treatment with epigenetic drugs (HDACis).

  11. Prognostic factors of breast cancer

    International Nuclear Information System (INIS)

    The prognostic factors must to be differentiated of the predictive ones. A prognostic factor is any measurement used at moment of the surgery correlated with the free interval of disease or global survival in the absence of the systemic adjuvant treatment and as result is able to correlate with the natural history of the disease. In contrast, a predictive factor is any measurement associated with the response to a given treatment. Among the prognostic factors of the breast cancer are included the clinical, histological, biological, genetic and psychosocial factors. In present review of psychosocial prognostic factors has been demonstrated that the stress and the depression are negative prognostic factors in patients presenting with breast cancer. It is essential to remember that the assessment of just one prognostic parameter is a help but it is not useful to clinical and therapeutic management of the patient.(author)

  12. Endocrine therapy of breast cancer

    International Nuclear Information System (INIS)

    This book results from a meeting of the ESO (European School of Oncology) Task Force on endocrine aspects of breast cancer. The contributions stem from some of the most outstanding researchers in Europe and highlight mainly methodological issues and new avenues for future research. The chapters on basic research deal primarily with experimental strategies for studying the relationship between steroid hormones, growth factors, and oncongenes. The clinically oriented chapters treat the methodology of clinical trials. Provocative questions are raised, such as: What are the pitfalls in endocrine trials? What does statistical proof mean? How can we consider a quality of life endpoint in the adjuvant setting? Two special reports deal with the controversial issues of chemoprevention in high-risk normal women and the optimization of the hormonal contribution to the adjuvant therapy of breast cancer. Topics considered included oncogenic transformations, radiotherapy, steroid hormones, cell proliferation, tamoxifen, and preventive medicine

    2009-01-01

    Most cases of breast cancer are diagnosed in older adults. Compared with younger women, older women as a group are at increased risk for breast-cancer-specific mortality and at higher risk for treatment-associated morbidity as well. At the same time, older women are less likely to be offered preventive care or adjuvant therapy for this disease. There are major gaps in evidence regarding the optimal evaluation and treatment of older women with breast cancer due to significant under-representat...

    Full Text Available linical trials have shown that the status of the women achieving complete pathomorphological repression (CPR of a tumor is characterized by significantly improved survival as compared to that of those who have not to an equal degree. The achievement of CPR as an intermediate marker for improved survival is chiefly observed in women with aggressive subtypes of breast cancer (BC: triple-negative and HER-2-positive. In patients with the latter subtype, addition of trastuzumab to neoadjuvant chemotherapy doubles the rate of CPR and correlates with higher survival rates. The performed clinical trials have established that neoadjuvant endocrine therapy is the most suitable treatment for patients with steroid hormone receptor overexpression. Whether it may be used in combination with targeted (anti-HER-2 therapy for estrogen and HER-2 coexpression is being investigated. Neoadjuvant therapy for suitable BC stages can accelerate the assessment of novel medications through identification of predictive biological markers for response (CPR in particular. Although standard neoadjuvant therapy gives an obvious benefit to patients with CPR, other patients with the so-called residual disease are at high recurrence risk.

    1999-03-01

    We have studied hair using fibre X-ray diffraction studies with synchrotron radiation and find that hair from breast-cancer patients has a different intermolecular structure to hair from healthy subjects. These changes are seen in all samples of scalp and pubic hair taken from women diagnosed with breast cancer. All the hair samples from women who tested positive for a mutation of the BRCA1 gene, which is associated with a higher risk of breast cancer, also show these changes. Because our results are so consistent, we propose that such hair analyses may be used as a simple, non-invasive screening method for breast cancer.

    To evaluate if the screening performance parameters of digital mammography (DM) in a decentralized screening organization were comparable with film-screen mammography (FSM). A nationwide screening program was launched in 2001, and since 2005 screening with DM has been allowed. Firstly, the parameters of the three regional screening units (RSUs) that first switched to DM (11,355 women) were compared with the FSM period of the same three RSUs (23,325 women). Secondly, they were compared with the results of the whole central breast unit (CBU). The recall rate (RR) of the DM group in the initial round was 2.64% [2.40% for FSM (p = 0.43)] and in the subsequent round 1.20% [1.58% for FSM (p = 0.03)]. The cancer detection rate (CDR) was 0.59% for DM and 0.64% for FSM (p = 0.56). The percentage of ductal carcinoma in situ was 0.07% for DM and 0.16% for FSM (p = 0.02). The positive predictive value was high in the subsequent rounds (DM 48.00%, FSM 45.93%) and lower in the initial round (DM 24.05%, FSM 24.86%). Compared with the results of the whole CBU, DM showed no significant difference. DM can be introduced in a decentralized screening organization with a high CDR without increasing the RR. (orig.)

    Full Text Available Ectopic or accessory breast tissue is most commonly located in the axilla, though it may be present anywhere along the milk line. Development is hormone dependent, similar to normal breast tissue. These lesions do not warrant any intervention unless they produce discomfort, thus their identification and distinction from other breast pathologies, both benign and malignant, is essential. We report a case with locally advanced breast cancer who presented with an ipsilateral axillary mass following surgery, radiotherapy, and chemotherapy. Subsequent evaluation with excision biopsy showed duct ectasia in axillary breast tissue and the patient was continued on hormone therapy with tamoxifen.

    Objective: To find an effective, sensitive, specific and noninvasive diagnostic method of breast cancer. Methods: 109 masses of 102 patients with breast lesions smaller than 2 cm in diameter were divided into three groups to undergo 99mTc-MIBI imaging and compared with the results of pathology examination. 20 cases without breast lesions were selected as control. Abnormal condensation of 99mTc-MIBI in the breast reaching 10% higher than that in the counterpart of the healthy breast was regarded as positive. Results: Of 32 breast cancers, positive imaging appeared in 25. Negative imaging were found in 31 of 38 benign breast lesions. Of 39 occult breast lesions, positive imaging appeared in 6 and 3 of them were breast cancer, 2 of 3 patients with slightly increased 99mTc-MIBI imaging threshold were breast cancer also. No positive imaging was found in the control group. The diagnostic accuracy, sensitivity, specificity, positive predictive value, negative predictive value of 99mTc-MIBI was 88.4%, 89.2%, 88.0%, 75.0% and 95.3%, respectively. Conclusion: 99mTc-MIBI imaging had higher sensitivity and accuracy in the diagnosis of breast cancer and differentiation between benign and malignant breast lesions. It could provide useful information for the diagnosis of clinically suspected breast cancer.

    Full Text Available Breast cancer is known from ancient time,and the treatment strategy evolved as our understanding of the disease changed with time. In 460 BC Hippocrates described breast cancer as a humoral disease and presently after a lot of studies breast cancer is considered as a local disease with systemic roots. For most of the twentieth century Halsted radical mastectomy was the "established and standardized operation for cancer of the breast in all stages, early or late". New information about tumor biology and its behavior suggested that less radical surgery might be just as effective as the more extensive one. Eventually, with the use of adjuvant therapy likeradiation and systemic therapy, the extent of surgical resection in the breast and axilla got reduced further and led to an era of breast conservation. The radiation treatment of breast cancer has evolved from 2D to 3D Conformal and to accelarated partial breast irradiation, aiming to reduce normal tissue toxicity and overall treatment time. Systemic therapy in the form of hormone therapy, chemotherapy and biological agents is now a well-established modality in treatment of breast cancer. The current perspective of breast cancer management is based on the rapidly evolving and increasingly integrated study on the genetic, molecular , biochemical and cellular basis of disease. The challenge for the future is to take advantage of this knowledge for the prediction of therapeutic outcome and develop therapies and rapidly apply more novel biologic therapeutics.

    Objective To investigate the diagnostic and prognostic value of total and free prostate-specific antigen (PSA) in breast cancer women. Methods Using the microparticle enzyme immunoassay system, we measured the concentrations of these markers in the sera of 85 women with breast cancer and in 30 healthy women.Results Free PSA levels were significantly higher in women with breast cancer than healthy women (P <0. 05 ).The percentage of free PSA predominant subjects was 37. 6% in breast cancer patients and 3. 3% in healthy women.In women with breast cancer,total PSA positivity was 23.5% and free PSA positivity was 27. 1%. When compared to negatives,total PSA positive patients had a higher percentage of lymph node involvement tamours ( P >0. 05).However, patients with predominant free PSA had a higher percentage of early stage than patients with predominant PSA-ACT. Conclusion This study indicate clinical significance of preoperative measurement of serum total and free PSA in diagnosis and prognosis of women with breast cancer. The expression of KLKs is correlated with carcinogenesis of breast cancer.

    Paclitaxel is widely used in the treatment of patients with metastatic breast cancer (MBC). Formulations of paclitaxel contain surfactants and solvents or albumin derived from human blood. The use of co-solvents such as polyoxyethylated castor oil is thought to contribute to toxicity profile and hypersensitivity reactions as well as leaching of plasticizers from polyvinyl chloride bags and infusion sets. Currently, nab-paclitaxel, an albumin-bound paclitaxel in nanometer range continues to be the preferred taxane formulation used in clinic. This study (CTRI/2010/091/001116) investigated the efficacy and tolerability of a polyoxyethylated castor oil- and albumin-free formulation of paclitaxel [paclitaxel injection concentrate for nanodispersion (PICN)] compared with nab-paclitaxel in women with refractory MBC. The current study was a multicenter, open-label, parallel-group, randomized, comparative phase II/III trial evaluating the efficacy and safety of PICN (260 mg/m(2) [n = 64] and 295 mg/m(2) [n = 58] every 3 weeks) compared with nab-paclitaxel (260 mg/m(2) every 3 weeks [n = 58]) in women 18 and 70 years old with confirmed MBC. Overall response rate (ORR) was assessed with imaging every 2 cycles. An independent analysis of radiologic data was performed for evaluable patients. Progression-free survival (PFS) was a secondary efficacy measure. Independent radiologist-assessed ORRs in the evaluable population of women aged ≥70 years were 35, 49, and 43 % in the PICN 260 mg/m(2), PICN 295 mg/m(2), and nab-paclitaxel 260 mg/m(2) arms, respectively. Median PFS in the evaluable population was 23, 35, and 34 weeks in the PICN 260 mg/m(2), PICN 295 mg/m(2), and nab-paclitaxel 260 mg/m(2) arms, respectively. Adverse events occurred in similar proportions of patients across treatment arms. Hypersensitivity reactions were not frequently observed with the clinical use of PICN across the treatment cohorts. In women with metastatic breast cancer, PICN at 260 and 295 mg/m(2

Methods: Study data was collected in community settings in New York City between the years of 2011-2012. Participants (N=592 were black and Hispanic individuals who attended a breast cancer screening community outreach program. Breast cancer screening rates as well as demographic data were collected. Results: Results revealed that Afro-Caribbean and foreign-born Hispanics are at a greater risk for non-adherence in breast cancer screening compared with African Americans and US-born Hispanics. Conclusions: The majority of breast screening research and community outreach programs categorize people into broad racial and ethnic groups (e.g., black and Hispanic. The results revealed significant variability within these broader racial/ethnic categories with regard to breast cancer screening. Community outreach programs and future research efforts should target the subpopulations that are at particular risk for breast cancer screening non-adherence.

In the current study, we analyzed the incidence of thyroid cancer and breast cancer in 50 US states and in the District of Columbia to ascertain how often these two diseases are associated. Methods: Data on the incidence of thyroid cancer were obtained from the Centers for Disease Control and Prevention and the National Cancer Institute and data on the incidence of breast cancer were from the American Cancer Society. Data on the average number of children per family with children and mean household income were sourced from the US Bureau of the Census and prevalence of obesity by state is determined from a paper published in 2010 on state-specific obesity prevalence among US adults by the Centers for Disease Control and Prevention. Results: There was a significant association between breast and thyroid cancer (P=0.002. Since the incidence of breast cancer increases with increasing income and obesity, while decreasing with parity, multiple linear regression was performed. Breast cancer incidence was significantly related to thyroid cancer incidence (β=0.271, P=0.039, inversely related to average number of children per family with children (β=-0.271, P=0.039, unrelated to adult obesity (β=0.134, P=0.369, and significantly related to family income (β=0.642, P<0.001. Conclusion: This study identifies an association between breast and thyroid cancer. The association suggests that unexplored breast-thyroid cancer susceptibility loci exist and warrant further study.

  12. Up-regulation of bone marrow stromal protein 2 (BST2) in breast cancer with bone metastasis

    International Nuclear Information System (INIS)

    Bone metastases are frequent complications of breast cancer. Recent literature implicates multiple chemokines in the formation of bone metastases in breast cancer. However, the molecular mechanism of metastatic bone disease in breast cancer remains unknown. We have recently made the novel observation of the BST2 protein expression in human breast cancer cell lines. The purpose of our present study is to investigate the expression and the role of BST2 in bone metastatic breast cancer. cDNA microarray analysis was used to compare the BST2 gene expression between a metastatic to bone human breast cancer cell line (MDA-231BO) and a primary human breast cancer cell line (MDA-231). The BST2 expression in one bone metastatic breast cancer and seven non-bone metastatic breast cancer cell lines were also determined using real-time RT-PCR and Western blot assays. We then employed tissue array to further study the BST2 expression in human breast cancer using array slides containing 20 independent breast cancer tumors that formed metastatic bone lesions, 30 non-metastasis-forming breast cancer tumors, and 8 normal breast tissues. In order to test the feasibility of utilizing BST2 as a serum marker for the presence of bone metastasis in breast cancer, we had measured the BST2 expression levels in human serums by using ELISA on 43 breast cancer patients with bone metastasis, 43 breast cancer patients without bone metastasis, and 14 normal healthy controls. The relationship between cell migration and proliferation and BST2 expression was also studied in a human breast recombinant model system using migration and FACS analysis. The microarray demonstrated over expression of the BST2 gene in the bone metastatic breast cancer cell line (MDA-231BO) compared to the primary human breast cancer cell line (MDA-231). The expression of the BST2 gene was significantly increased in the bone metastatic breast cancer cell lines and tumor tissues compared to non-bone metastatic breast cancer

    The present study evaluated dose distribution in the male breast using thermoluminescent dosimeters (TLDs). The rate of male breast cancers has increased in recent years, due to the deficiency of preventive examinations (male mammography). Still, male breasts have smaller volumes than female breasts, thus, from the point of view of radiation protection, it is essential to monitor the doses received by the male breast, as well as those received by healthy and critical organs in order to evaluate radiotherapy performance and aid treatment planning. For this reason, the treatment of male breast cancer was simulated with the radiation by linear accelerator in Alderson Rando phantom and doses were measured with thermoluminescent dosimeters. The results of the treatment planning and measured were compared. (author)

    Current use of menopausal hormone therapy (MHT) has important implications for postmenopausal breast cancer risk, and observed associations might be modified by known breast cancer susceptibility loci. To provide the most comprehensive assessment of interactions of prospectively collected data on MHT and 17 confirmed susceptibility loci with invasive breast cancer risk, a nested case-control design among eight cohorts within the NCI Breast and Prostate Cancer Cohort Consortium was used. Based on data from 13,304 cases and 15,622 controls, multivariable-adjusted logistic regression analyses were used to estimate odds ratios (OR) and 95 % confidence intervals (CI). Effect modification of current and past use was evaluated on the multiplicative scale. P values <1.5 × 10(-3) were considered statistically significant. The strongest evidence of effect modification was observed for current MHT by 9q31-rs865686. Compared to never users of MHT with the rs865686 GG genotype, the association between current MHT use and breast cancer risk for the TT genotype (OR 1.79, 95 % CI 1.43-2.24; P interaction = 1.2 × 10(-4)) was less than expected on the multiplicative scale. There are no biological implications of the sub-multiplicative interaction between MHT and rs865686. Menopausal hormone therapy is unlikely to have a strong interaction with the common genetic variants associated with invasive breast cancer. PMID:26802016

    This paper presents the development of a prototype Tactile Mapping Device (TMD) system comprised mainly of a tactile sensor array probe (TSAP), a 3-D camera, and a force/torque sensor, which can provide the means to produce tactile maps of the breast lumps during a breast palpation. Focusing on the key tactile topology features for breast palpation such as spatial location, size/shape of the detected lesion, and the force levels used to demonstrate the palpable abnormalities, these maps can record the results of clinical breast examination with a set of pressure distribution profiles and force sensor measurements due to detected lesion. By combining the knowledge of vision based, neural networks and tactile sensing technology; the TMD is integrated for the investigation of soft tissue interaction with tactile/force sensor, where the hard inclusion (breast cancer) can be characterized through neural network learning capability, instead of using simplified complex biomechanics model with many heuristic assumptions. These maps will serve as an objective documentation of palpable lesions for future comparative examinations. Preliminary results of simulated experiments and limited pre-clinical evaluations of the TMD prototype have tested this hypothesis and provided solid promising data showing the feasibility of the TMD in real clinical applications.

  1. Primary breast cancer: European radiotherapy trials

    International Nuclear Information System (INIS)

    For many years in Europe, surgically operable breast carcinomas have been treated by conservative treatments. There are two methods of conservative treatment: limited surgery with or without auxiliary dissection followed by irradiation and irradiation as the primary treatment. Depending on the size of the primary tumor and clinical findings in the axillae, patients were referred to either of the two treatment alternatives. Generally, limited surgery and irradiation was performed in patients with early breast carcinomas, while irradiation as the primary treatment was used for more locally advanced cancers. Since 1960, conservative treatments with megavoltage for patients with invasive breast carcinomas have been used more and more frequently. These conservation methods have been used hoping to achieve long-term survival comparable to that obtained by mastectomy and breast preservation with good cosmetic results. This chapter reviews results at 5 and 10 years obtained in Europe by several authors concerning early breast infiltration carcinomas treated by limited surgery or without axillary dissection followed by irradiation

    2003-10-01

    Breast cancer is the most commonly occurring cancer in women. The lifetime risk of being diagnosed with breast cancer is approximately 1 in 10 thereby the highest out of all cancers. Breast cancer screening programs have been shown to decrease the mortality rates of women between ages 50-69, since cancers are detected at an earlier, more favourable stage. It is apparent that the development of breast cancer is a slow process following initial transformation of the breast tissue. Hence, there has been a strong effort within the research community to understand risk factors for the disease. Risk factors are defined as those characteristics that are more common in people with the disease when compared to the normal population. Quantification of an individual's breast cancer rate may lead that individual to modify her lifestyle and/or diet. Lifestyle changes could lead to a reduction in the incidence of breast cancer. Anatomically, the presence of increased amounts of fibroglandular tissue raises the estimated risk by up to 6 fold (correct for age), hence representing one of the strongest known risk factors pertaining to the entire female population. In this study the relative area of mammographic densities within a mammogram will be used as a global risk assessment tool. It has been shown previously that quantification of water, lipids, haemoglobin and other tissue chromophores of the optically interrogated breast tissue, which also gives rise to the mammographic densities, is feasible through near-infrared spectroscopy. Thus, the hypothesis for this study is that optical transillumination spectroscopy provides consistent and/or complementary information to conventional mammography in quantifying breast tissue density.

    Full Text Available Abstract Background The overall incidence of male breast cancer is around 1% of all breast cancers and is on the rise. In this review we aim to present various aspects of male breast cancer with particular emphasis on incidence, risk factors, patho-physiology, treatment, prognostic factors, and outcome. Methods Information on all aspects of male breast cancer was gathered from available relevant literature on male breast cancer from the MEDLINE database over the past 32 years from 1975 to 2007. Various reported studies were scrutinized for emerging evidence. Incidence data were also obtained from the IARC, Cancer Mondial database. Conclusion There is a scenario of rising incidence, particularly in urban US, Canada and UK. Even though more data on risk factors is emerging about this disease, more multi-institutional efforts to pool data with large randomized trials to show treatment and survival benefits are needed to support the existing vast emerging knowledge about the disease.

  10. Bilateral breast cancer: an evaluation of risk factors and outcome

    International Nuclear Information System (INIS)

    PURPOSE: To compare the outcome of bilateral breast cancer patients to that of patients with unilateral disease. MATERIALS AND METHODS: From 1960-1995, 1254 stage O/I/II/III patients with primary breast cancer were treated by either mastectomy or breast conservation therapy at Thomas Jefferson University Hospital. There were 1141 (91.2%) unilateral, 41 (3.1%) synchronous and 65 (5.7%) metachronous breast cancer patients. Synchronous breast cancers were defined as having a second cancer diagnosis within one year of initial diagnosis. There were 46.2% of patients stage O/I at initial diagnosis, while 68% were stage O/I at subsequent diagnosis. For the metachronous breast cancers, the median interval between first and second diagnosis was 44 months (range of 13-287 months). Median follow-up time was 58 months for the synchronous cancers (15-218 months) and 107 months (21-360 months) for the metachronous cancers. Overall and NED survival, local control and distant metastatic disease rates from the time of the first and second diagnosis were calculated for the synchronous and metachronous patients. These were then compared to the unilateral breast cancer patients and to each other. RESULTS: Synchronous bilateral breast cancer patients had a worse 5 and 10 year NED survival rate (71.2% and 57.0%) compared to the unilateral patients (83.8% and 77.8%) p=.015 and also a higher distant metastasis rate (70.6% and 54.9% vs. 83.5% and 77.8%) (p=.005). Local control and overall survival comparisons were not statistically significant in this group when compared to unilateral patients. There was also no difference noted when comparing metachronous to unilateral patients for the above parameters. When analyzing metachronous and synchronous patients there was a trend revealing a worse NED survival at 5 and 10 years (84.5% and 82.2% vs. 71.2% and 57% p=.07) and a higher metastatic rate (85.9% and 80.9% vs. 70.6% and 54.9% p=.01) in the synchronous group. CONCLUSION: We conclude that

  14. Immunohistochemical study of estrogen receptors and progesterone in breast cancer

    International Nuclear Information System (INIS)

    Presence of estrogen receptors in breast tumors allows to judge about sensitivity of cancer to hormone therapy and diseases prognosis. Objective of the study is to compare histological forms of patient's age and various estrogen receptors combination in breast cancer. 30 patients were undergone to immune-histo-chemical examination of breast tumors in the Semipalatinsk cancer clinic. According to expression of estrogen and testosteron receptors they were divided into 4 groups. The most wide-spread histologic type of cancer was dust-infiltrative. This type took place of 3.3 % for the first group, 9.9 % for the second group, 16-6 % for the third one, and 36.6 % for the fourth one. Histological type of cancer had not effects on expression of receptors estrogen and progesterone in tumor. Rare breast cancer types like medullary occurred only in the fourth group. Dividing breast cancer into positive and negative or with expression of one hormone depending on expression of estrogen, testosteron receptors may be regarded as a sensible way. More expanded examination on immune-histo-chemical markers allows extending topics regarding therapy of breast cancer. (author)

  15. Dosimetric prospective study comparing 2D and 3D planning for irradiation of supraclavicular and infraclavicular regions in breast cancer patients

    International Nuclear Information System (INIS)

    Purpose: The purpose of this study is to compare 2D plan and 3D plan regarding coverage of the target (supraclavicular and infraclavicular regions) and dose reaching the risk organs (using mean DVH). Depending on the results of this study, modifications can be made to the 2D conventional planning of supraclavicular and infraclavicular regions in order to achieve better coverage of the target tissues. Materials and methods: This is a dosimetric study carried out at the radiation oncology department in NCI-Cairo University in the period from January 2012 to October 2012, on 15 patients with breast cancer who are eligible for supraclavicular and infraclavicular irradiation. For All patients, a 2D and a 3D plan were done. Results: We found that the coverage of the supraclavicular and infraclavicular regions and the chest wall or breast together with levels I and II axilla (PTV) were significantly better with the 3D technique with less over dose than the 2D technique. That difference was highly significant and was most evident in MRM cases. Also we found that organs at risk received a dose in the 3D technique that was more than that received in the 2D technique, again that difference was highly significant and was also most evident in MRM cases but all doses were still within tolerance. Conclusions: From the present study we concluded that the coverage of the supraclavicular and infraclavicular PTV is significantly worse with the 2D technique using a single oblique field at a fixed depth of 3 cm for all patients despite their different builts.

  16. Breast cancer stem cells and radiation

    Science.gov (United States)

    Phillips, Tiffany Marie

    2007-12-01

    The present studies explore the response of breast cancer stem cells (BCSC's) to radiation and the implications for clinical cancer treatment. Current cancer therapy eliminates bulky tumor mass but may fail to eradicate a critical tumor initiating cell population termed "cancer stem cells". These cells are potentially responsible for tumor formation, metastasis, and recurrence. Recently cancer stem cells have been prospectively identified in various malignancies, including breast cancer. The breast cancer stem cell has been identified by the surface markers CD44+/CD24 -(low). In vitro mammosphere cultures allow for the enrichment of the cancer stem cell population and were utilized in order to study differential characteristics of BCSC's. Initial studies found that BCSC's display increased radiation resistance as compared to other non-stem tumor cells. This resistance was accompanied by decreased H2AX phosphorylation, decreased reactive oxygen species formation, and increased phosphorylation of the checkpoint protein Chk1. These studies suggest differential DNA damage and repair within the BCSC population. Studies then examined the consequences of fractionated radiation on the BCSC population and found a two-fold increase in BCSC's following 5 x 3Gy. This observation begins to tie cancer stem cell self-renewal to the clinical stem cell phenomenon of accelerated repopulation. Accelerated repopulation is observed when treatment gaps increase between sequential fractions of radiotherapy and may be due to cancer stem cell symmetric self-renewal. The balance between asymmetric and symmetric stem cell division is vital for proper maintenance; deregulation is likely linked to cancer initiation and progression. The developmental Notch-1 pathway was found to regulate BCSC division. Over-expressing the constitutively active Notch-1-ICD in MCF7 cells produced an increase in the BCSC population. Additionally, radiation was observed to increase the expression of the Notch-1

  19. IMRT technique in patients with breast cancer treated with breast conserving therapy - obstacles and advantages

    International Nuclear Information System (INIS)

    Breast cancer is the most frequently occurring type of malignant tumour in women in Poland. About 12 thousand new cases of breast cancer are registered annually, among which the greater part (70-80%) is represented by women in the early phase of the disease. Conserving therapy is the standard approach in early breast cancer. The role of radiotherapy as a supplement to surgical treatment is also underlined. For over 100 years radiotherapy has been one of the basic methods to treat patients with malignant tumour of the breast. Nowadays the use of ionizing radiation has become an integral method of the multidisciplinary and modern treatment of patients with breast cancer after conserving surgery. Within the last few years the improvement of radiotherapy techniques has been observed to correct the therapeutic index of radiation. The modulation of the intensity of the beam (intensity modulated radiation therapy, IMRT) is a new method of radiotherapy which assures delivery of the highest possible radiation dose into the area of the tumour with the simultaneous maximum protection of healthy tissues. The purpose of this study is to set out the present state of knowledge on possibilities of using the technique of IMRT on patients with breast cancer after conserving therapy. In the article available literature is reviewed and an analysis of the advantages and disadvantages of using IMRT in breast cancer compared to standard conformal techniques is presented. (authors)
