[source] Predictors of Mastectomy in a Certified Breast Center , The Surgeon is an Independent Risk FactorTHE BREAST JOURNAL, Issue 4 2008Roland Reitsamer MD Abstract:, The current study examined predictors of mastectomy in a certified breast center with the main impact on the factor surgeon. A total of 663 patients were analyzed for their mastectomy rates. Included were patients with T1 and T2 tumors, who had their surgery performed by one of three specialized breast surgeons with a workload of at least 50 new breast cancer cases per year. On multivariate analysis central tumor localization, positive lymph node status, nonunifocality, large tumor size, and the surgeon were independent predictors of mastectomy. Surgeon A had a mastectomy rate of 30.5% (50/164), surgeon B 26.9% (43/160) respectively, and surgeon C had a mastectomy rate of 15.8% (27/171), p = 0.005. Patients, who had surgery performed by surgeon A or surgeon B were 2.34 [95% confidence interval (CI): 1.38,3.97, p < 0.005] respectively 1.96 (95% CI: 1.14,3.36, p = 0.01) times as likely to have a mastectomy than patients who had surgery performed by surgeon C. Even in a certified breast center with specialized breast surgeons the surgeon is an independent risk factor of mastectomy, as the tumor criteria are given at the time of diagnosis. [source] Local Recurrence of Breast Cancer after Skin-Sparing Mastectomy Following Core Needle Biopsy: Case Reports and Review of the LiteratureTHE BREAST JOURNAL, Issue 3 2006Juan Luis Uriburu MD Abstract: The latest advances in diagnostic and therapeutic procedures for breast cancer have provided valuable technological breakthroughs. Yet the long-term consequences of these modern methods are still quite unclear. Such is the case for stereotactic or ultrasound-guided histologic needle biopsy and skin-sparing mastectomy. We report on three patients who presented with multicentric breast cancer diagnosed by stereotactic needle biopsy and treated by skin-sparing mastectomy. All three patients developed recurrence at the core needle entry site. Records of 58 patients with breast cancer who were treated by skin-sparing mastectomy followed by immediate reconstruction (with transverse rectus abdominis muscle [TRAM] flap or tissue expander) at the Breast Diseases Division of Buenos Aires British Hospital between December 1999 and December 2003 were reviewed retrospectively. Eleven of these patients were diagnosed by histologic needle biopsy. The mean follow-up was 28 months (range 5,60 months). Three (skin or subcutaneous) local recurrences at the needle entry site, diagnosed in a mean time of 23.6 months (16, 22, and 23 months), were reported. The three patients underwent complete resection with clear margins, radiation therapy to the "neobreast," and tamoxifen. All three patients are disease free with a mean postrecurrence follow-up of 24.3 months (30, 23, and 22 months). Based on the evidence of displacement of tumor cells and the potential nonresection of such tumor seeding at the time of skin-sparing mastectomy, as well as the poor probability of postoperative radiation therapy, we recommend surgical resection of the needle biopsy tract, including the dermal entry site, at the time of mastectomy. [source] Autofluorescence and diffuse reflectance spectroscopy and spectral imaging for breast surgical margin analysisLASERS IN SURGERY AND MEDICINE, Issue 1 2010Matthew D. Keller MS Abstract Background and Objective Most women with early stage breast cancer have the option of breast conserving therapy, which involves a partial mastectomy for removal of the primary tumor, usually followed by radiotherapy. The presence of tumor at or near the margin is strongly correlated with the risk of local tumor recurrence, so there is a need for a non-invasive, real-time tool to evaluate margin status. This study examined the use of autofluorescence and diffuse reflectance spectroscopy and spectral imaging to evaluate margin status intraoperatively. Materials and Methods Spectral measurements were taken from the surface of the tissue mass immediately following removal during partial mastectomies and/or from tissues immediately after sectioning by surgical pathology. A total of 145 normal spectra were obtained from 28 patients, and 34 tumor spectra were obtained from 12 patients. Results After correlation with histopathology, a multivariate statistical algorithm classified the spectra as normal (negative margins) or tumor (positive margins) with 85% sensitivity and 96% specificity. A separate algorithm achieved 100% classification between neo-adjuvant chemotherapy-treated tissues and non-treated tissues. Fluorescence and reflectance-based spectral images were able to demarcate a calcified lesion on the surface of a resected specimen as well. Conclusion Fluorescence and reflectance spectroscopy could be a valuable tool for examining the superficial margin status of excised breast tumor specimens, particularly in the form of spectral imaging to examine entire margins in a single acquisition.

[source] Breast Reconstruction after Bilateral Prophylactic Mastectomy in Women at High Risk for Breast CancerTHE BREAST JOURNAL, Issue 2009Liron Eldor MD Abstract:, Several studies have shown the effectiveness of bilateral prophylactic mastectomies (BPM) at reducing the risk of developing breast cancer in women by more than 90%. A growing number of women at high risk for breast cancer are electing to undergo prophylactic mastectomy as part of a risk reduction strategy. This unique group of women frequently chooses to undergo reconstructive surgery as a part of their immediate treatment plan. Breast reconstruction after BPM has profound physiological and emotional impact on body image, sexuality, and quality of life. These factors should be taken into consideration and addressed when consulting the patient prior to BPM and reconstructive surgery. The timing of reconstructive surgery, the type of mastectomy performed, the reconstructive modalities available, and the possibility to preserve the nipple,areola complex, should all be discussed with the patient prior to surgery. In this article, we review our experience and the current existing literature on breast reconstruction for high-risk women after BPM.

[source] Areolar Cosmetic Tattoo Ink Darkening: A Complication of Q-Switched Alexandrite Laser TreatmentDERMATOLOGIC SURGERY, Issue 1 2002Sung-Eun Chang MD background and objective. Medical tattooing of the areola is widely performed in Korea. However, cosmetic tattoos containing flesh-tone, purple-red, and yellow dyes are sometimes resistant to Q-switched laser and may even become darker. method. Two Korean women in their 30s who had a mastectomy got light brown to red areolar medical tattoos but they were not satisfied with the shape and size of the tattoos. They underwent Q-switched alexandrite laser treatment with a 3 mm collimated beam at fluences of 7.5,8 J/cm2 in order to trim the irregular contour and reduce the diameter of the tattoos. results. Within 5 minutes a dark gray to black discoloration of the treated area was evident and remained dark for 6 weeks. Improvement was not noted after two further Q-switched Nd:YAG laser treatments. conclusion. Medical areolar tattoos should be approached with extra caution when attempting their removal with high-energy pulsed lasers such as Q-switched alexandrite laser and a small test site should be performed prior to treatment. [source] Synchronous metastases to the liver and pancreas from a primary neuroendocrine carcinoma of the breast diagnosed by fine-needle aspirationDIAGNOSTIC CYTOPATHOLOGY, Issue 1 2008Maria McIntire M.D. Abstract Extrapulmonary neuroendocrine carcinoma is uncommon. Cases of primary neuroendocrine carcinoma of the breast have been reported, though rare. We report the case of a 53-year-old woman who underwent a mastectomy for breast carcinoma and presented three years later with synchronous masses in the head of the pancreas and liver. Fine-needle aspiration of both organs revealed a neuroendocrine carcinoma. The original breast tumor was reviewed and found to express neuroendocrine markers. A diagnosis of a primary neuroendocrine carcinoma of the breast was rendered. Diagn. Cytopathol. 2008;36:54,57. © 2007 Wiley-Liss, Inc. [source] Development of three different neoplasias in a patient in an 18-year period of timeEUROPEAN JOURNAL OF CANCER CARE, Issue 3 2010P. HERAS md HERAS P., GEORGOPOULOU A.P., HATZOPOULOS A. & KRITIKOS K. (2010) European Journal of Cancer Care 19, 413,416 Development of three different neoplasias in a patient in an 18-year period of time This study presents a rare case of a patient who developed three different types of neoplasia in an 18-year period of time. The case presents a 31-year-old man with a history of treated Hodgkin's lymphoma in the neck region at the age of 13 years. The patient was admitted at the General Hospital of Nafplio for differential diagnosis of pain in the right subcostal region initiated 1 month before his admission and normochromic, normocytic anaemia. The laboratory examinations lead to the diagnosis of a sarcoma in the cardioesophageal junction. The patient was subjected to total gastrectomy. Nine months later he is admitted with a palpable firm lump in the nipple of the right breast, which suggested a malignant neoplasia. The patient was subjected to modified radical mastectomy. The appearance of three different types of neoplasia in three different organ systems in the same patient and the infrequency of the specific neoplasias individually and in combination present a special interest considering the patient's genetic background and the uniqueness of the case in the international literature. [source] ERBB2, TBX2, RPS6KB1, and MYC alterations in breast tissues of BRCA1 and BRCA2 mutation carriersGENES, CHROMOSOMES AND CANCER, Issue 1 2004Camilo Adem Breast cancer risk is greatly increased in women who carry mutations in the BRCA1 or BRCA2 genes. Because breast cancer initiation is different between BRCA1/2 mutation carriers and women who do not carry mutations, it is possible that the mechanism of breast cancer progression is also different. Histopathologic and genetic studies have supported this hypothesis. To test this hypothesis further, we utilized a large cohort of women who underwent therapeutic mastectomy (TM) and contralateral prophylactic mastectomy (PM). From this cohort, we developed case groups of women with a family history of breast cancer with BRCA1/2 deleterious mutations, with unclassified variant alterations, and with no detected mutation and matched these cases with sporadic controls from the same TM and PM cohort. Fluorescence in situ hybridization was performed on paraffin sections by use of dual-color probes for ERBB2/CEP17, MYC/CEP8, TBX2/CEP17, and RPS6KB1/CEP17. All malignant and benign lesions, including putative precursor lesions, were studied. The invasive cancers from deleterious mutation carriers had a higher prevalence of duplication of MYC (P = 0.006) and TBX2 (P = 0.0008) compared to controls and a lower prevalence of ERBB2 amplification (P = 0.011). Coduplication of MYC and TBX2 was common in the in situ and invasive lesions from the deleterious mutation carriers. The odds ratio of having a BRCA1/2 mutation is 31.4 (95% CI = 1.7,569) when MYC and TBX2 are coduplicated but ERBB2 is normal. Unclassified variant carriers/no mutation detected and sporadic controls had a similar prevalence of alterations, suggesting that hereditary patients with no deleterious mutations follow a progression pathway similar to that of sporadic cases. With the exception of one atypical ductal hyperplasia lesion, no putative precursor lesion showed any detectable alteration of the probes tested. There was no significant intratumoral heterogeneity of genetic alterations. Our data confirm that a specific pattern of genomic instability characterizes BRCA1/2 -related cancers and that this pattern has implications for the biology of these cancers. Moreover, our current and previous results emphasize the interaction between phenotype and genotype in BRCA1/2 -related breast cancers and that a combination of morphologic features and alterations of ERBB2, MYC, and TBX2 may better define mechanisms of tumor progression, as well as determine which patients are more likely to carry BRCA1/2 mutations. © 2004 Wiley-Liss, Inc. [source] Resolution of Menstrually Related Migraine Following Aggressive Treatment for Breast CancerHEADACHE, Issue 3 2010Todd A. Smitherman PhD (Headache 2010;50:485-496) Hormonal influences associated with the female menstrual cycle play strong roles in both migraine and particular types of breast cancer, but there is limited literature on the effects of breast cancer treatment regimens in women with migraine. The present case describes resolution of menstrually related migraine following aggressive treatment for infiltrating ductal carcinoma (neoadjuvant chemotherapy, single radical mastectomy, and locoregional radiation therapy) that was maintained with supplemental treatment using tamoxifen, an anti-estrogenic agent. This novel case is presented to stimulate further research into the hormonal mechanisms underlying migraine. [source] Use of instrumental variables in the presence of heterogeneity and self-selection: an application to treatments of breast cancer patientsHEALTH ECONOMICS, Issue 11 2007Anirban Basu Abstract Instrumental variable (IV) methods are widely used in the health economics literature to adjust for hidden selection biases in observational studies when estimating treatment effects. Less attention has been paid in the applied literature to the proper use of IVs if treatment effects are heterogeneous across subjects and individuals select treatments based on expected idiosyncratic gains or losses from treatments. In this paper we compare conventional IV analysis with alternative approaches that use IVs to estimate treatment effects in models with response heterogeneity and self-selection. Instead of interpreting IV estimates as the effect of treatment at an unknown margin of patients, we identify the marginal patients and we apply the method of local IVs to estimate the average treatment effect and the effect on the treated on 5-year direct costs of breast-conserving surgery and radiation therapy compared with mastectomy in breast cancer patients. We use a sample from the Outcomes and Preferences in Older Women, Nationwide Survey which is designed to be representative of all female Medicare beneficiaries (aged 67 or older) with newly diagnosed breast cancer between 1992 and 1994. Our results reveal some of the advantages and limitations of conventional and alternative IV methods in estimating mean treatment effect parameters. Copyright © 2007 John Wiley & Sons, Ltd. [source] Racial/Ethnic Disparities in Knowledge about Risks and Benefits of Breast Cancer Treatment: Does It Matter Where You Go?HEALTH SERVICES RESEARCH, Issue 4 2008Sarah T. Hawley Objective. To evaluate the association between provider characteristics and treatment location and racial/ethnic minority patients' knowledge of breast cancer treatment risks and benefits. Data Sources/Data Collection. Survey responses and clinical data from breast cancer patients of Detroit and Los Angeles SEER registries were merged with surgeon survey responses (N=1,132 patients, 277 surgeons). Study Design. Cross-sectional survey. Multivariable regression was used to identify associations between patient, surgeon, and treatment setting factors and accurate knowledge of the survival benefit and recurrence risk related to mastectomy and breast conserving surgery with radiation. Principal Findings. Half (51 percent) of respondents had survival knowledge, while close to half (47.6 percent) were uncertain regarding recurrence knowledge. Minority patients and those with lower education were less likely to have adequate survival knowledge and more likely to be uncertain regarding recurrence risk than their counterparts (p<.001). Neither surgeon characteristics nor treatment location attenuated racial/ethnic knowledge disparities. Patient,physician communication was significantly (p<.001) associated with both types of knowledge, but did not influence racial/ethnic differences in knowledge. Conclusions. Interventions to improve patient understanding of the benefits and risks of breast cancer treatments are needed across surgeons and treatment setting, particularly for racial/ethnic minority women with breast cancer. [source] A case of erythema elevatum diutinum associated with breast carcinomaINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 11 2005Fikriye Yilmaz MD A 53-year-old woman diagnosed with invasive ductal-type breast carcinoma was referred to our clinic with red,purple lesions on the hands and legs. She had neither pruritus nor pain. The first lesion developed on the dorsal hand. In the following days, new lesions appeared on the extensor surface of the legs. The patient had been treated with modified radical mastectomy and three courses of cyclophosphamide, adriamycin, and fluorouracil chemotherapy. Dermatologic examination revealed reddish-violaceous papules and plaques ranging from a few millimeters to 2 cm in diameter, bilaterally located on the dorsal hands, especially over the metacarpophalangeal and interphalangeal joints (Fig. 1). Multiple red,purple, circumscribed papules and plaques of various diameters were observed bilaterally over the shins (Fig. 2). The largest of these plaques showed an annular configuration. The nails showed distal subungual keratosis and yellow discoloration. The rest of the physical examination was normal. Figure 1. Violaceous papules and plaques on the dorsal hands Figure 2. Red,purple, circumscribed, papules and plaques over the shins A biopsy taken from the medial side of the shin revealed a predominantly neutrophilic infiltrate and nuclear dust around the dermal vessels and orthokeratotic stratum corneum (Fig. 3). Figure 3. Predominantly neutrophilic infiltrate and nuclear dust around the dermal vessels and orthokeratotic stratum corneum (hematoxylin and eosin stain, ×100) Complete blood count, routine biochemical tests and fasting lipids, serologic tests of bacterial and viral agents, serum electrophoresis, and serologic profiles for autoimmune connective tissue diseases revealed normal results. Mycologic examination of nail clippings did not show any evidence of fungal infection. In the light of our clinical and histopathologic findings, a diagnosis of erythema elevatum diutinum was made, and the patient was given topical clobetasol propionate therapy. Complete clearance was achieved in 3 weeks (Fig. 4). After six courses of cyclophosphamide, adriamycin, and fluorouracil chemotherapy, and radiotherapy, no recurrence of erythema elevatum diutinum lesions was observed. Figure 4.

SOLDEVILLA Abstract A 69-year-old hypertensive woman presented with eye and mouth dryness, bilateral parotid gland enlargement, associated with anasarca and proteinuria. Family history was notable for malignancies including breast, nasopharyngeal and colon cancers. Physical exam disclosed hypertension, bilaterally enlarged, firm, non-tender parotid glands, fine bibasilar crackles and bipedal edema. Anti Ro/Sjögren's syndrome antigen A antibody was positive, with negative tests for anti La/Sjögren's syndrome antigen B and anti-nuclear antibody (ANA). Chest radiographs showed basal infiltrates. Sjögren's syndrome associated with glomerulonephritis and interstitial lung disease was diagnosed, and she received pulse methylprednisololone followed by oral prednisone with dramatic improvement. Two months later, while on prednisone 5 mg/day, she returned to the clinic with an enlarging fixed non-tender right breast mass. She underwent modified radical mastectomy of the right breast, and pathologic report revealed diffuse, small cell, non-Hodgkin's lymphoma of the breast; axillary lymph nodes were negative for tumor. She opted for alternative therapy and did not return to the clinic until 7 months later when she developed sudden monocular blindness in the right eye with no other systemic manifestations. Magnetic resonance imaging (MRI) revealed swelling and enhancement of intracanalicular and pre-chiasmatic segments of the right optic nerve and right side of the optic chiasm. Considerations were Devic's disease versus metastases. She received pulse methylprednisolone therapy (1 g/day for 3 days) with partial recovery of vision. She is scheduled for lymphoma chemotherapy to include rituximab. [source] Functional intravascular volume deficit in patients before surgeryACTA ANAESTHESIOLOGICA SCANDINAVICA, Issue 4 2010M. BUNDGAARD-NIELSEN Background: Stroke volume (SV) maximization with a colloid infusion, referred to as individualized goal-directed therapy, improves outcome in high-risk surgery. The fraction of patients who need intravascular volume to establish a maximal SV has, however, not been evaluated, and there are only limited data on the volume required to establish a maximal SV before the start of surgery. Therefore, we estimated the occurrence and size of the potential functional intravascular volume deficit in surgical patients. Methods: Patients scheduled for mastectomy (n=20), open radical prostatectomy (n=20), or open major abdominal surgery (n=20) were anaesthetized, and before the start of surgery, a 200 ml colloid fluid challenge was provided and repeated if a ,10% increment in SV estimated by oesophageal Doppler was established. The volume needed for SV maximization defined the intravascular volume deficit. Results: Forty-two (70%) of the patients needed volume to establish a maximal SV. For the patients needing volume, the required amount was median 200 ml (range 200,600 ml), with no significant difference between the three groups of patients. The required volume was ,400 ml in nine patients (15%). Conclusion: The majority of anaesthetized patients present with a functional intravascular volume deficit before surgery. Although the deficit in general was minor, a fraction of patients presented with a deficit that may be of clinical relevance, emphasizing the importance of the individual approach of goal-directed fluid therapy. [source] Epithelioid angiosarcoma of the breast involving the skin: a highly aggressive neoplasm readily mistaken for mammary carcinomaJOURNAL OF CUTANEOUS PATHOLOGY, Issue 2 2003M. C. Fariña Background: Angiosarcomas are malignant neoplasms of endothelial cells. Angiosarcoma of the breast is a rare neoplasm that behaves in a highly malignant fashion. It must be differentiated from benign vascular proliferations and from mammary carcinoma. Methods: We report on a 49-year-old-woman who presented with a large mass involving the left breast. Results: The lesion had an erythematoviolaceous hue and livedoid pattern at the periphery. Histopathologic study showed an epithelioid malignant neoplasm, and immunohistochemical studies demonstrated that neoplastic cells expressed immunoreactivity for endothelial cell markers. Conclusions: A diagnosis of epithelioid angiosarcoma of the breast was established. The patient was treated with radical mastectomy, but she refused any other additional therapy. [source] SAPHO syndrome masquerading as metastatic bone diseaseJOURNAL OF MEDICAL IMAGING AND RADIATION ONCOLOGY, Issue 5 2005NH Theumann Summary A 46-year-old woman who had had a right mastectomy for breast carcinoma a month before underwent bone scintigraphy. The examination revealed multiple pelvic, vertebral and sternal hot spots suggestive of bone metastases. Standard X-rays and CT confirmed the presence of bony lesions but they were not typical of bone metastases. As the radiographic appearance was reminiscent of SAPHO syndrome (synovitis, acne, pustulosis, hyperostosis, osteitis), bone biopsies were performed. Histology showed fibrosis and hyperostosis but no tumour cells. On further questioning, the patient revealed she had had palmar pustulosis and sacroiliitis some years earlier. The purpose of the case report is to show that accurate diagnosis of SAPHO syndrome requires careful clinical and radiological examinations. [source] Effects of postoperative ketamine infusion on pain control and feeding behaviour in bitches undergoing mastectomyJOURNAL OF SMALL ANIMAL PRACTICE, Issue 12 2007S. Sarrau Objectives: To determine if ketamine administered to bitches at the end of a mastectomy, followed by a six-hour constant rate infusion (CRI), improved postoperative opioid analgesia and feeding behaviour. Methods: The bitches were randomised into three groups: the placebo group received 0·09 ml/kg isotonic saline intravenously followed by a six-hour CRI of 0·5 ml/kg/hour, the low-dose ketamine received 150 ,g/kg ketamine intravenously followed by a six-hour CRI of 2 ,g/kg/minute and the high-dose ketamine group received 700 ,g/kg ketamine intravenously followed by a six-hour CRI of 10 ,g/kg/minute. Any additional opioids given were recorded at the time of extubation and at intervals after extubation. Food intake was evaluated eight (T8) and 20 (T20) hours after extubation by measuring the per cent coverage of basal energy requirements (BER). Results: No significant difference was observed for opioid requirements between the three groups. The mean percentages of BER coverage did not differ significantly at T8 but the difference between the high-dose and low-dose ketamine groups (P=0·014), and the high-dose ketamine and placebo groups (P=0·038) was significant at T20. Clinical Significance: This study demonstrated that 700 ,g/kg ketamine given intravenously postoperatively followed by a six-hour ketamine CRI of 10 ,g/kg/minute improved patient feeding behaviour. [source] Is pleomorphic lobular carcinoma really a distinct clinical entity?JOURNAL OF SURGICAL ONCOLOGY, Issue 5 2008Claire L. Buchanan MD Abstract Background Attempts to define the clinical behavior of pleomorphic lobular carcinoma (PLC) have been limited to small series, and clinical management strategies have yet to be established. We describe our experience with PLC as compared to classic ILC and invasive ductal carcinoma (IDC). Methods From 9/1996 to 5/2003, clinical and histopathologic data for 5,635 patients undergoing primary surgical treatment and sentinel lymph node biopsy for breast cancer were collected. Four hundred eighty one (8.5%) patients were diagnosed with ILC; 3,978 (70.6%) with IDC. Of those with ILC, 356 (74%) patients had material available for pathologic re-review and comprise our study population: 52 were classified as PLC; 298 were classified as classic ILC; and 6 cases were reclassified as IDC. We compared clinical, pathologic, and treatment factors for patients with PLC, ILC, and IDC using the Wilcoxon rank sum and Fisher's exact tests. Results PLC were larger than ILC and IDC (20 vs. 15 vs. 13, P,<,0.001), had more positive nodes (median 1 vs. 0 vs. 0, P,<,0.05) and more frequently required mastectomy (63.5% vs. 38.7% vs. 28.8%, P,<,0.001). In addition, more patients with PLC had developed metastatic disease compared to patients with ILC (11.5% vs. 3.7%, P,<,0.05). Conclusions These findings suggest that PLC is a distinct clinical entity that presents at a more advanced stage and may require more aggressive surgical and adjuvant treatment. J. Surg.

[source] Primary sarcoma of the breastJOURNAL OF SURGICAL ONCOLOGY, Issue 3 2004Manoj Pandey Abstract Background and Objectives Primary sarcoma occurring in breast is rare and comprises 0.5,1% of all breast neoplasm. Majority of the series include both stromal and cystosarcoma phyllodes, only a few hundred cases of sarcomas other then cystosarcoma are reported. Patients and Methods We carried out a retrospective analysis of 19 patients with primary sarcoma of the breast treated between 1982 and 2002. Results Mean age of the patients was 38.6 years (12,70 years). Gradually progressive swelling was the commonest presenting feature. There were eight cases of angiosarcoma, four cases of spindle cell sarcoma, two each of pleomorphic sarcoma and stromal sarcoma, and one each of malignant fibrous histiocytoma, embryonal rhabdomyosarcoma, and sarcoma (NOS). Eight of these were high-grade (42%). Eight patients underwent either radical or modified mastectomy, three underwent wide excisions, and one underwent quadrantectomy. Ten (52.6%) patients received postoperative adjuvant radiation. Two patients received chemotherapy. After a mean follow-up time of 34.5 months (median 25 months), eight patients failed. Failure was local in five, opposite breast in one, and both local and distant in two. The disease free survival at 3-year was 39%. In univariate analysis only the margin of first surgery was found to be a significant predictor of survival (P,=,0.05). Conclusions Primary sarcomas of the breast are aggressive tumors. Surgical treatment should consist of at least simple mastectomy. All attempts should be made to achieve a negative margin as this appears to be the only factor influencing survival in these patients.

[source] In vitro interaction between mouse breast cancer cells and mouse mesenchymal stem cells during adipocyte differentiationJOURNAL OF TISSUE ENGINEERING AND REGENERATIVE MEDICINE, Issue 5 2009Feng Xu Abstract Surgical treatment following breast cancer, i.e. lumpectomy and mastectomy, may not efficiently remove all cancerous cells. As such, when mesenchymal stem cells (MSCs) are incorporated into the breast reconstruction process, it is likely that those MSCs will encounter remnant cancerous cells after transplantation into the defect site. The potential interaction between breast cancer cells and MSCs remains unclear. We hypothesized that paracrine interactions might occur between cells and various proteinases, growth factors and other cytokine molecules in the local microenvironment. Conditioned media (CM) from two mouse mammary cancer cell lines (4T1 and 4T07) and one mouse mammary epithelial cell line (NMuMG) were studied in the experimental model. Post-confluent mouse MSCs (D1 cells) were differentiated with an adipogenic hormonal cocktail. Conditioned media from the three cell types did not have an inhibitory effect on D1 cell viability; however, triglyceride (TG) and Oil red O (ORO) analysis results showed that 4T1-CM significantly inhibited D1 adipocyte differentiation and reduced lipid vesicle accumulation in the differentiating D1 cells. Preliminary analysis of the conditioned media revealed that a higher presence of matrix metalloprotease-9 (MMP-9) and urokinase plasminogen activator (uPA) was present in the 4T1-CM as compared to the levels found in 4T07-CM and NMuMG-CM, which were below the detection limit. Additionally, the conditioned medium of differentiated D1 cells on day 12 had a negative effect on 4T1 and 4T07 cell viability but no effect on NMuMG cell viability. The results suggest that mouse breast cancer cells modulate mouse MSC adipogenic differentiation, the level of modulation specific to the metastatic level. Copyright © 2009 John Wiley & Sons, Ltd.

[source] Histologic classification of ductal carcinoma in situMICROSCOPY RESEARCH AND TECHNIQUE, Issue 2 2002Shabnam Jaffer Abstract Prior to the current mammographic era, ductal carcinoma in situ (DCIS) usually presented as a large mass, was classified morphologically by architecture, and treated by mastectomy. The introduction of screening mammography led to an increase in the incidence of DCIS, a decrease in the average size of DCIS, and an increased emphasis on its heterogeneous nature. Thus, a reproducible and prognostically relevant classification system for DCIS is necessary. The ultimate goal of this classification is proper selection of patients for whom lumpectomy would suffice rather than mastectomy. Features to evaluate include: extent and size of disease, adequacy of resection margins, and histology. While none of the proposed histological classification systems were endorsed at the recent Consensus Conference on the Classification of DCIS, nuclear grade was the most important feature common to most of them. Architecture was given secondary importance. By definition, DCIS is a non-invasive clonal proliferation of epithelial cells originating in the terminal duct lobular unit, which would be expected to be monomorphic; however, it is the degree of nuclear pleomorphism that is primarily used to separate DCIS into low, intermediate, and high grades. Architecturally, DCIS has been divided into the following types: comedo, solid, cribriform, micropapillary, and papillary. Different architectural patterns and grades may be present in a given particular case; however, some combinations of patterns occur more frequently than others. Interobserver studies have shown nuclear grading to be interpreted with greater consistency than architecture, and nuclear grading methods have correlated with biological and molecular marker studies.

[source] Muco-epidermoid carcinoma of the breastPATHOLOGY INTERNATIONAL, Issue 9 2006Rie Horii A very rare case of muco-epidermoid carcinoma of the breast is reported. A 54-year-old woman noticed a breast lump and consulted the Cancer Institute Hospital, Tokyo. Physical examination revealed a mass with an unclear margin in the upper outer area of the left breast. Both mammography and ultrasonography showed an irregularly shaped mass, suggesting invasive carcinoma. Aspiration cytology revealed solid clusters of two types of cancer cells: ones with mucus in the cytoplasm, and others without mucus. Cytological features resembled muco-epidermoid carcinoma of the salivary gland but it was not possible to establish a diagnosis of the histological type because muco-epidermoid carcinoma of the breast had not previously been encountered by the authors. After incisional biopsy, left mastectomy with axillary lymph node dissection was performed. Histologically the tumor was surrounded by a fibrous pseudocapsule and was composed of intraductal carcinoma foci and invasive cancer nests. Intraductal carcinoma foci were the low papillary type. Stromal invasion showed many solid nests composed of mucus-containing and squamoid cancer cells. There was no common invasive ductal carcinoma component in this tumor. These histological features confirmed the diagnosis as muco-epidermoid carcinoma of the breast. This is the first report of muco-epidermoid carcinoma of the breast in Japan. [source] Signet-ring cell carcinoma of the breastPATHOLOGY INTERNATIONAL, Issue 1 2000Shian-Min Liu Primary signet-ring cell carcinoma of the breast is a very rare tumor and is not recognized as an independent entity of the World Health Organization classification of breast tumor. Primary signet-ring cell carcinoma of the breast is usually considered as a variant of mucinous carcinoma or lobular carcinoma and usually originates from the lobular epithelium. A case of primary signet-ring cell carcinoma of the breast in a 68-year-old woman is presented. Histologically, the majority of neoplastic cells had an intracytoplasmic mucin collection. The histological presence of ductal carcinoma in situ, absence of lobular lesion and immunoreactivity for estrogen and progesterone receptors implicated the tumor cells arising from ductal epithelium. The papillary or organoid growth pattern is characteristic in this case. The patient underwent a modified radical mastectomy and was subsequently followed up for 6 months. [source] Influence of some anthropometric parameters on the risk of development of distal complications after mastectomy carried out because of breast carcinomaAMERICAN JOURNAL OF HUMAN BIOLOGY, Issue 3 2003Zbigniew Kopanski The analysis included 46 women after radical breast amputation because of cancer with which lymphoedema occurred in the upper limb, as well as 51 women in whom no lymphoedema occurred during the period of the observation. Both groups were subjected to a comparative analysis as for height, body mass, and weight,height indexes: BMI, Quetelet, Rohrer, and Pignet,Verwaeck. The results show that women with high body mass, obesity (BMI > 30.0), and high values of the Quetelet (>370), Rohrer (>1.59), and Pignet,Verwaeck (>93.1) indexes are threatened to a significant degree with lymphoedema of the upper limbs after cancer-related mastectomy. On the other hand, slim body build and low index values appear to be a factor protecting from the occurrence of lymphoedema of the upper limb. Am. J. Hum.

[source] Support needs and acceptability of psychological and peer consultation: attitudes of 108 women who had undergone or were considering prophylactic mastectomyPSYCHO-ONCOLOGY, Issue 8 2008Andrea F. Patenaude Abstract Objective: Prophylactic mastectomy (PM) offers 90% or greater reduction in risk of breast cancer to women at increased hereditary risk. Nonetheless, acceptance in North America is low (0,27%) and 25,50% of women electing surgery report psychological distress and/or difficulty adapting following PM. Most women also report reduced cancer worry postoperatively. Psychological consultation to aid decision-making and post-surgical coping is not routinely offered. This retrospective, cross-sectional study explored interest in and acceptability of psychological consultation for issues related to PM among 108 women who had undergone or were considering surgery. Method: Qualitative interviews were conducted with 26 healthy women who had undergone prophylactic mastectomy of both (bilateral) breasts (BPM), 45 women who had undergone prophylactic mastectomy of one breast (unilateral contralateral) (UPM) after diagnosis of invasive breast cancer in the other breast or ductal carcinoma in situ (DCIS), and 37 women who were considering having PM surgery. Results: Of the women who had undergone PM, more than half felt pre-surgical psychological consultation was advisable; nearly 2/3 thought post-surgical psychological consultation would be helpful. All women currently considering PM believed psychological consultation would aid decision-making and preparation for surgery. Strong support was reported in all groups for the emotional and informational value of speaking with a woman who had previously undergone PM. Conclusions: Narratives illustrate the nature and intensity of the need for psychological support and describe preferences for the role of the psychologist. Suggestions are offered for integration of psychological services for women deciding about or adapting to PM. Copyright © 2008 John Wiley & Sons, Ltd. [source] Body image and sexual problems in young women with breast cancerPSYCHO-ONCOLOGY, Issue 7 2006Pat Fobair Abstract Purpose: The purpose of this study was to determine the frequency of body image and sexual problems in the first months after treatment among women diagnosed with breast cancer at age 50 or younger. Background: Breast cancer treatment may have severe effects on the bodies of younger women. Surgical treatment may be disfiguring, chemotherapy may cause abrupt menopause, and hormone replacement is not recommended. Methods: A multi-ethnic population-based sample of 549 women aged 22,50 who were married or in a stable unmarried relationship were interviewed within seven months of diagnosis with in situ, local, or regional breast cancer. Results: Body image and sexual problems were experienced by a substantial proportion of women in the early months after diagnosis. Half of the 546 women experienced two or more body image problems some of the time (33%), or at least one problem much of the time (17%). Among sexually active women, greater body image problems were associated with mastectomy and possible reconstruction, hair loss from chemotherapy, concern with weight gain or loss, poorer mental health, lower self-esteem, and partner's difficulty understanding one's feelings. Among the 360 sexually active women, half (52%) reported having a little problem in two or more areas of sexual functioning (24%), or a definite or serious problem in at least one area (28%). Greater sexual problems were associated with vaginal dryness, poorer mental health, being married, partner's difficulty understanding one's feelings, and more body image problems, and there were significant ethnic differences in reported severity. Conclusions: Difficulties related to sexuality and sexual functioning were common and occurred soon after surgical and adjuvant treatment. Addressing these problems is essential to improve the quality of life of young women with breast cancer. Copyright © 2005 John Wiley & Sons, Ltd. [source] Psychosocial functioning in women who have undergone bilateral prophylactic mastectomyPSYCHO-ONCOLOGY, Issue 1 2004Kelly A. Metcalfe The purpose of this study was to determine the current psychosocial functioning of women who had previously had a bilateral prophylactic mastectomy. Women in the province of Ontario who had undergone prophylactic mastectomy between 1991 and 2000 were asked to complete questionnaires that assessed psychological distress, sexual activity, overall satisfaction with decision to have a prophylactic mastectomy, and body image. Ninety-seven percent of the women were satisfied with their decision to have a prophylactic mastectomy, but young women (<50 years) were less likely to report satisfaction than older women (p=0.001). Women with a strong family history of breast cancer or a BRCA1 or BRCA2 mutation experienced more cancer-related distress than those with a limited family history. Women who had reconstruction following mastectomy reported higher levels of satisfaction with general body shape and appearance than those without reconstruction. In conclusion, the majority of women were satisfied with their decision to undergo prophylactic mastectomy and were not experiencing abnormal levels of psychological distress, low levels of sexual activity, or difficulties with body image.
