    An in vitro study was designed to evaluate the uptake of sestamibi (MIBI) in P-glycoprotein (Pgp) and glutathione-associated (GSH) multidrug-resistant (MDR) cell lines. MIBI uptake was studied in various human breast carcinoma cell lines, i.e. in wild-type (MCF7/wt) cells, in adriamycin-resistant (MCF7/adr) cells which express Pgp and in melphalan-resistant (MCF7/mph) cells with increased levels of GSH. The effects of buthiomine sulphoximine (BSO) and verapamil on MIBI uptake were also studied in the MCF7/mph and MCF7/adr cells respectively. The cells were incubated for 1 h with a dose of 0.1 MBq thallium-201 and technetium-99m MIBI. Both BIBI and 201 Tl uptakes were higher for MCF7/mph cells than for the other cells studied. The mean MIBI uptake in MCF7/adr cells was significantly lower than that in MCF7/wt cells (1.9%±0.5% vs 3.1%.0.6%; P 0.1). This study suggests that the uptake of MIBI is not diminished by glutathione-associated drug resistance and that MIBI uptake in a tumour sample does not necessarly indicate that a cancer is sensitive to drugs.

    The medical records of patients with pregnancy associated breastcarcinoma were critically reviewed to identify the tumor characteristics,maternal details, type of treatment delivered and disease outcome. Over thelast 5 years, there were 5 patients out of 220 giving a percentage prevalenceof 2.27%. The median age at presentation was 33 years. Three patients werediagnosed by the sixth week of gestational age. Three out of 5 presented withstage IIIA. Four patients has >6 positive axillary lymph nodes and grade IIIdisease. So in spite of the discovery of the tumor in the early weeks ofpregnancy, our patients presented with advanced disease, which is consistentwith the presentation of breast carcinoma in non-pregnant women in this partof the world. So it could be an ignored disease, which become evident withthe pregnancy. We highly encourage the obstetricians to perform thoroughbreast examination during the prenatal period with prompt referral of anysuspicious cases. (author)

    Full Text Available Continual increasing of breast cancer in young women, its rare discovery in the early stage (stage I, as well as high mortality from this disease, are the facts that explain why the breast cancer is a target for many scientists. Thanks to the Greek scientist Papanicolaou and his report (l928, a successful battle with the most frequent carcinoma in women - PVU carcinoma, has begun.With the development of exfoliative, brushing and fine needle aspiration cytological methods, the impressive results have been achieved. While cytologic methods are used more and more in the breast oncopathology worldwide, up to this moment their applications have been rare in our country, which is one more reason for this study reason more for this study.By using the exfoliative and fine needle aspiration cytology, 50 patients were examined. The following cells were discovered: foamy macrophages, lipoprotein background, mastitis, eritrocytes, ductal tumorous papilles, apocrine metaplasia and ductal carcinomas. Furthermore, cytological caracteristics of the breast cancers and both advantages and limitations of the cytologic methods were pointed out. It was concluded that, using cytological methods, discovery of both precancerous breast lesions and breast cancer was possible in the earli stage. Also, sufficient knowledge of histopathology was necessary for correct interpretation of cytological results because of frequent mimicry in oncologic pathology.

    We evaluate 311 breast cancer patients admitted to Yong Dong Severance Hospital Between October 1st 1985 and July 31th 1989, and were able to obtain the following conclusions. 1) There were 14(4.5%) bilateral breast cancers among the 311 confirmed breast cancers. 2) Among the bilateral breast cancers, 5(31%) were synchronous and 9(69%) metachronous. 3) Average interval between the first and the second breast cancer in metachronous cancers was 3.8 year(1-15 years). 4) Bilateral breast cancer was most prevalent in the fifth decade (6/14) with the mean age of 47 years. 5) Film mammogram and sonomammogram showed findings of typical breast malignancies. There was no additional specific findings for each cancer in bilateral breast cancers which was different from unilateral cancers. Therefor, in the patients with unilateral breast cancer, possibility of the second lesion in the contralateral side must be considered and a close follow up observation should be done for at least 3 years

    Circumscribe breast cancer is a well demarcated mass with or without a lobulated border simulating a benign tumor like fibroadenoma on mammography or breast US and is reported as approximate 10% of the incidence among primary breast carcinoma(1.2). Pathologically medullary, colloid, papillary, intraductal and rarely invasive ductal carcinomas are included in this group which show the less intense desmoplastic reaction than the scirrhous type cancer, resulting in the most favorable prognosis of all carcinoma of the breast. Among 214 primary breast carcinoma during the past 8 years, we experienced 6 case of pathologically proven circumscribed breast cancer(2 cases of medullary carcinoma, 1 of colloid carcinoma, 1 of intracystic papillary carcinoma, 2 of comedo type intraductal carcinoma). Clinically 2 cases showed bloody nipple discharge from one hole of a unilateral nipple orifice. Mammography showed a well circumscribed nodule with or without partial lobular contour and no pathologic calcification. Breast sonographic findings were a well defined heterogeneous hypoechoic nodule with weak posterior acoustic enhancement. Characteristically a thin dilated lactiferous duct between the mass and the nipple on US could be detected in 2 cases which clinically was accompanied by bloody nipple discharge. Although the mammographic criteria is promising as benign tumor, the possibility of circumscribed as benign tumor, the possibility of circumscribed breast carcinoma must be considered in heterogeneous hypoechoic nodule with weak posterior acoustic enhancement in US, especially in the presence of a dilated lactiferous duct between the mass and the nipple with bloody nipple discharge.

    Mammography has proven to be an effective modality for the detection of early breast carcinoma. However, 4-34 percent of breast cancers may be missed at mammography. Delayed diagnosis of breast carcinoma results in an unfavourable prognosis. The objective of this study was to determine the causes and characteristics of breast carcinomas missed by mammography at our institution, with the aim of reducing the rate of missed carcinoma. We reviewed the reports of 13,191 mammograms performed over a five-year period. Breast Imaging Reporting and Data Systems (BI-RADS) were used for the mammographical assessment, and reports were cross-referenced with the histological diagnosis of breast carcinoma. Causes of missed carcinomas were classified. Of 344 patients who had breast carcinoma and had mammograms done prior to surgery, 18 (5.2 percent) failed to be diagnosed by mammography. Of these, five were caused by dense breast parenchyma obscuring the lesions, 11 were due to perception and interpretation errors, and one each from unusual lesion characteristics and poor positioning. Several factors, including dense breast parenchyma obscuring a lesion, perception error, interpretation error, unusual lesion characteristics, and poor technique or positioning, are possible causes of missed breast cancers.

    Background Metaplastic carcinomas are ductal carcinomas that display metaplastic transformation of the glandular epithelium to non-glandular mesenchymal tissue. Metaplastic carcinoma has a poorer prognosis than most other breast cancers, so the differential diagnosis is important. Although many clinical and pathologic findings have been reported, to our knowledge, few imaging findings related to metaplastic carcinoma have been reported. Purpose To investigate whole-breast imaging findings, including mammography, sonography, MRI, and pathologic findings, including immunohistochemical studies of metaplastic carcinomas of the breast. Material and Methods We analyzed 33 cases of metaplastic carcinoma between January 2001 and January 2011. Mammography, ultrasonography, and MRI were recorded retrospectively using the American College of Radiology (ACR) breast imaging reporting and data system (BI-RADS) lexicon. Immunohistochemical studies of estrogen receptor (ER), progesterone receptor (PR), p53, and C-erbB-2 were performed. Results The most common mammographic findings were oval shape (37%), circumscribed margin (59%), and high density (74%). The most common sonogfindings were irregular shape (59.4%), microlobulated margin (41%), complex echogenicity (81%), parallel orientation (97%), and posterior acoustic enhancement (50%). Axillary lymph node metastases were noted for 25% of the sonographic examinations. On MRI, the most common findings of margin and shape were irregularity (57% and 52.4%, respectively). High signal intensity was the most common finding on T2-weighted images (57%). Immunohistochemical profile was negative for ER (91%, 29/32) and PR (81%, 26/32). Conclusion Metaplastic carcinomas might display more benign features and less axillary lymph node metastasis than IDC. High signal intensity on T2 MRI images and hormone receptor negativity would be helpful in differentiating this tumor from other breast cancers

    Lib, first identified as a novel beta-amyloid responsive gene in rat astrocytes, has an extracellular domain of 15 leucine-rich repeats (LRRs) followed by a transmembrane domain and a short cytoplasmic region. It is a distinctly inducible gene and is thought to play a key role in inflammatory states via the LRR extracellular motif, an ideal structural framework for protein-protein and protein-matrix interactions. To evaluate potential roles of Lib, we screened various tumors for Lib expression. Lib mRNA expression was high and uniquely expressed in breast tumor tissues, compared to paired normal breast tissues. Lib mRNA was localized in the ductal carcinoma cells and Lib protein displayed a homophilic association on the surface of cultured cells. These data suggest that Lib may play a role in the progression of breast carcinomas and may be a diagnostic marker for breast tumors.

    Among 910 survivors of childhood cancer, four developed infiltrating carcinoma of the breast and another had noninfiltrating breast tumor. Expected frequency was 0.3 cases of breast cancer in the series. The affected women developed breast carcinoma at ages 20, 25 and 38 years, and the men at ages 38 and 39 years, respectively. Each patient had received orthovoltage chest irradiation for treatment of Wilms' tumor or bone sarcoma between seven and 34 years previously, and estimated radiation dose to the breast exceeded 300 rad in each instance. Four patients also received diverse forms of chemotherapy. Survivors of childhood cancer have increased risk of developing breast cancer and should undergo periodic screening, particularly after breast tissue had been irradiated. Individualized radiotherapy planning can help exclude the breasts from treatment fields for some thoracic neoplasms

    Neuroendocrine breast carcinomas (NBCs) account for 2–5% of all invasive breast cancers and are histologically similar to neuroendocrine tumours from other sites. They typically express oestrogen receptor (ER), are HER2-negative and of luminal 'intrinsic' subtype. Here we sought to define the mutational profile of NBCs, and to investigate whether NBCs and common forms of luminal (ER+/HER2-) breast cancer display distinct repertoires of somatic mutations. Eighteen ER+/HER2- NBCs, defined as harbouring >50% of tumour cells expressing chromogranin A and/or synaptophysin, and matched normal tissue were microdissected and subjected to massively parallel sequencing targeting all exons of 254 genes most frequently mutated in breast cancer and/or related to DNA repair. Their mutational repertoire was compared to that of ER+/HER2- (n=240), PAM50-defined luminal breast cancers (n=209 luminal A; n=111 luminal B) and invasive lobular carcinomas (n=127) from The Cancer Genome Atlas. NBCs were found to harbour a median of 4.5 (range 1-11) somatic mutations, similar to that of luminal B breast cancers (median=3, range 0-17) but significantly higher than that of luminal A breast cancers (median=3, range 0-18, p=0.02). The most frequently mutated genes were GATA3, FOXA1, TBX3, ARID1A (3/18, 17%), and PIK3CA, AKT1, CDH1 (2/18, 11%). NBCs less frequently harboured PIK3CA mutations than common forms of ER+/HER2, luminal A and invasive lobular carcinomas (pcancers. No TP53 somatic mutations were detected in NBCs. Compared to common forms of luminal breast cancers, NBCs display a distinctive repertoire of somatic mutations featuring lower frequency of TP53 and PIK3CA mutations, and enrichment for FOXA1, TBX3 mutations, and akin to neuroendocrine tumours from other sites, ARID1A mutations.

    Skeletal imaging using radionuclides has proved to be a sensitive method for the detection of early bony metastases from breast carcinoma. Recent studies have found a relatively low rate of abnormal scans in patients with stage I and II breast cancers, and therefore it is open to question whether bone scanning should be part of the preoperative evaluation of any patient prior to breast surgery. We reviewed our experience with bone scans in 329 patients out of 406 histologically proven breast cancer patients to determine if any or all patients should have this procedure done routinely prior to breast surgery.

    A ten year experience with 2,077 consecutive mammographically guided needle-localization biopsies at a large community hospital is presented. By using this technique, 13.8 per cent of the biopsies were positive, yielding 284 carcinomas. The nonpalpable carcinomas discovered by mammography and the needle-localization technique were compared with those palpable carcinomas diagnosed during the same time period at York Hospital. In the final year of the study, 42.1 per cent of carcinomas treated at the York Hospital were diagnosed by the needle-localization technique. The mammographically detected carcinomas were smaller, more often node-negative and found, on average, at an earlier patient age than palpable carcinomas. The results of this study demonstrate that screening mammography, coupled with an aggressive biopsy policy, will lead to the discovery of many early, node-negative carcinomas of the breast.

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

    Full Text Available Carcinoma of the breast is one of the commonest cancers occurring in female and accounts for 1/3rd of all the malignant diseases occurring in them. It is mainly a disease of the developed countries and accounts for 1,00,000 deaths annually. Breast carcinoma is classified as Early breast cancer, Locally advanced breast cancer and Metastatic breast cancer. By definition early stage breast cancer constitutes breast tumors of clinical stages I, IIa and T2N1M0. Early breast cancer is the one diagnosed by mammography. Women when approaches at this stage, they can go for breast conservation surgery. Not all women are candidates for this approach, and some require mastectomy as part of their treatment. AIM To observe the incidence of early breast carcinoma with particular reference to the time taken by the patients to seek medical advice after the symptoms have developed i.e. the average time taken by the patients to seek medical advice, their appropriate management and prognosis. MATERIALS AND METHODS This prospective study was conducted over a period of 2 years from Oct-2012 to Oct-2014 in 30 female patients aged between 25-65 years who were presented with lump in breast of size ≤5cms with or without pain, with or without lymph nodes to the outpatient department. All the patients were thoroughly asked about history, examined clinically, investigated, staged and managed by surgery either Breast Conservation Surgery or Modified Radical Mastectomy. Postoperative complications were recorded and followed up regularly. RESULTS The incidence of early breast cancer in this study was 0.98% with peak age incidence between 40-60 years and duration of symptoms <6 months in 18 patients. Breast Conservation Surgery + axillary dissection + Radiotherapy was done in 23%. Prognosis was good in these patients with no local recurrence and death. CONCLUSION The prognosis of early stage breast carcinoma patients in this study was good. To have long term tumor free and

    Full Text Available Mucinous carcinoma is also known as mucoid carcinoma, colloid carcinoma, gelatinous carcinoma and mucin producing carcinoma. They are uncommon neoplasms of the breast and the reported incidence varies from 1-4%. Most of the mucinous carcinomas occur in older age group. FNAC can aid in diagnosis of mucinous carcinoma with only a few FNAC studies documented in literature. We present here a 56year old lady with a huge ulcerated breast mass clinically diagnosed as Malignant Phyllodes tumor. An FNAC was done which showed epithelial cell clusters with mild atypia in a background of both bluish violet and pink extracellular material. Spindle shaped cells were noted in the ground substance which led to a diagnosis of a phyllodes tumor with extensive myxoid change. Mastectomy was performed and the histopathological features confirmed a diagnosis of mucinous carcinoma. The tumor had areas showing thick collagenized fibrous septae separating tumor cell clusters and also areas of fibrosis. The pitfall in FNAC diagnosis may be due to the sampling from such an area.

    Full Text Available Inflammatory breast carcinoma is an extremely rare, rapidly progressive breast carcinoma which is a great masquerader and often is mistaken as an inflammatory lesion. This leads to the delay in diagnosis. Here, we report such a case where the mistaken clinical diagnosis led to it being treated with antibiotics. However, fine-needle aspiration cytology of the case saved the day. Histopathological confirmation followed by multimodal therapy was rendered, and the patient responded well to the treatment. Thus, awareness and recognition of this rare entity, which mimics various inflammatory and nonmalignant causes, is of paramount importance for the doctors and patients alike.

    2012-01-01

    Full Text Available Ductal carcinoma in situ (DCIS of the breast represents a complex, heterogeneous pathologic condition in which malignant epithelial cells are confined within the ducts of the breast without evidence of invasion. The increased use of screening mammography has led to a significant shift in the diagnosis of DCIS, accounting for approximately 27% of all newly diagnosed cases of breast cancer in 2011, with an overall increase in incidence. As the incidence of DCIS increases, the treatment options continue to evolve. Consistent pathologic evaluation is crucial in optimizing treatment recommendations. Surgical treatment options include breast-conserving surgery (BCS and mastectomy. Postoperative radiation therapy in combination with breast-conserving surgery is considered the standard of care with demonstrated decrease in local recurrence with the addition of radiation therapy. The role of endocrine therapy is currently being evaluated. The optimization of diagnostic imaging, treatment with regard to pathological risk assessment, and the role of partial breast irradiation continue to evolve.

    This review explores the mechanistic basis of breast carcinoma progression by focusing on the contribution of integrins. Integrins are essential for progression not only for their ability to mediate physical interactions with extracellular matrices but also for their ability to regulate signaling pathways that control actin dynamics and cell movement, as well as for growth and survival. Our comments center on the alpha6 integrins (alpha6beta1 and alpha6beta4), which are receptors for the laminin family of basement membrane components. Numerous studies have implicated these integrins in breast cancer progression and have provided a rationale for studying the mechanistic basis of their contribution to aggressive disease. Recent work by our group and others on mechanisms of breast carcinoma invasion and survival that are influenced by the alpha6 integrins are discussed.

    Full Text Available Invasive lobular carcinoma is the second most common type of invasive breast cancer accounting for approximately 5-10% of all invasive breast carcinomas. The metastatic patterns of lobular and ductal carcinomas are significantly different. Most series report a greater propensity for lobular carcinoma to metastasize to the gastrointestinal tract, gynecological organs and the peritoneum, while ductal carcinoma most frequently relapses in the liver, lungs and the brain. Gastrointestinal system metastases were observed in 6-18%, the most commonly affected organ is the stomach. We aimed to present a female patient who had been diagnosed with invasive lobular carcinoma of the breast ten years ago and had invasive ductal carcinoma of the other breast three years ago, investigated for excessive ascites and found to have invasive lobular breast carcinoma metastasis to the stomach.

    Full Text Available Cancer of the male breast is an uncommon event with metastases to the breast occurring even less frequently. Prostate carcinoma has been reported as the most frequent primary to metastasize to the breast; however, the reverse has not been previously reported. Herein, we present, for the first time, a case of breast carcinoma metastasizing to the prostate gland. Prostate needle core biopsy revealed infiltrative nests of neoplastic epithelioid cells, demonstrated by immunohistochemistry (IHC to be positive for GATA3 and ER and negative for PSA and P501S. A prostate cocktail by IHC study demonstrated lack of basal cells (p63 and CK903 and no expression of P501S. The patient’s previous breast needle core biopsy showed strong ER positivity and negative staining for PR and HER2. Similar to the prostate, the breast was negative for CK5/6, p63, and p40. This case demonstrates the importance of considering a broad differential diagnosis and comparing histology and IHC to prior known malignancies in the setting of atypical presentation or rare tumors.

    Full Text Available Metastasis to the thyroid gland is very rare. Recently, we experienced a case of thyroid metastasis from breast cancer accompanying a papillary thyroid. A 51-year-old female patient presented with a palpated lymph node on her left lateral neck. The patient had undergone a left modified radical mastectomy followed by chemotherapy and hormonal therapy 12 years prior. Ultrasonography of the neck revealed a malignant looking nodule at the left thyroid lobe, measuring 0.9 × 0.9 cm, and several cystic nodules at the right thyroid lobe. Ultrasonography of the neck additionally revealed a malignant looking lymph node at the right level VI. Fine-needle aspiration of the left thyroid lobe resulted in a diagnosis of papillary thyroid carcinoma and that of the right level VI in Hurthle cell lesion. The patient had a total thyroidectomy with selective dissection of the left neck node. Pathologic assessment of the specimen revealed metastatic carcinoma from the breast carcinoma and papillary thyroid carcinoma. Although the thyroid gland is highly vascularized, metastasis of malignant tumors to the thyroid is relatively rare and detection of metastasis shows a low frequency. So a careful evaluation of thyroid tumor should be considered in a patient with a history of other malignancy.

    Seven cases of mucinous (colloid) breast carcinoma were studied by electron microscopy. In addition to the predictably abundant mucosubstance production, the following observations merit elaboration: 1) absence of myoepithelial differentiation and basal lamina deposition, 2) notably developed cytoplasmic filamentous systems and relatively scarce lysosomes, 3) frequent and apparently well-developed intercellular junctions, and 4) a distinct paucity of vessels in the tumors' stroma. The rather favorable clinical prognosis of mucinous breast carcinoma despite the absence of myoepithelial differentiation and basal lamina deposition parallel observations made on medullary and tubular breast carcinomas, thus confirming that those parameters, however important, are not the sole determinants of an aggresive behavior. The conspicuous cytoplasmic filaments appear to be neither true myoepithelial filaments or tonfilaments. The peculiar arrangement of these contractile proteins and the suspected sarcity of lysosomal collagenases may be reflected in the rather low invasiveness of these carcinomas. Another factor that may impact favorably on the cohesiveness of these neoplastic cell clusters is the presence of abundant and well-developed intercellular junctions. We further speculate that the paucity of stromal vessels in these neoplasms may be the result of as yet unidentified factors that might inhibit angiogenesis.

    While the deregulation of iron homeostasis in breast epithelial cells is acknowledged, iron-related alterations in stromal inflammatory cells from the tumor microenvironment have not been explored. Immunohistochemistry for hepcidin, ferroportin 1 (FPN1), transferrin receptor 1 (TFR1) and ferritin (FT) was performed in primary breast tissues and axillary lymph nodes in order to dissect the iron-profiles of epithelial cells, lymphocytes and macrophages. Furthermore, breast carcinoma core biopsies frozen in optimum cutting temperature (OCT) compound were subjected to imaging flow cytometry to confirm FPN1 expression in the cell types previously evaluated and determine its cellular localization. We confirm previous results by showing that breast cancer epithelial cells present an ‘iron-utilization phenotype’ with an increased expression of hepcidin and TFR1, and decreased expression of FT. On the other hand, lymphocytes and macrophages infiltrating primary tumors and from metastized lymph nodes display an ‘iron-donor’ phenotype, with increased expression of FPN1 and FT, concomitant with an activation profile reflected by a higher expression of TFR1 and hepcidin. A higher percentage of breast carcinomas, compared to control mastectomy samples, present iron accumulation in stromal inflammatory cells, suggesting that these cells may constitute an effective tissue iron reservoir. Additionally, not only the deregulated expression of iron-related proteins in epithelial cells, but also on lymphocytes and macrophages, are associated with clinicopathological markers of breast cancer poor prognosis, such as negative hormone receptor status and tumor size. The present results reinforce the importance of analyzing the tumor microenvironment in breast cancer, extending the contribution of immune cells to local iron homeostasis in the tumor microenvironment context

    Adenoid cystic carcinoma (AdCC) is a rare type of triple-negative breast cancer (TNBC) characterized by the presence of the MYB-NFIB fusion gene. The molecular underpinning of breast AdCCs other than the MYB-NFIB fusion gene remains largely unexplored. Here we sought to define the repertoire of somatic genetic alterations of breast AdCCs. We performed whole-exome sequencing, followed by orthogonal validation, of 12 breast AdCCs to determine the landscape of somatic mutations and gene copy number alterations. Fluorescence in situ hybridization and reverse-transcription PCR were used to define the presence of MYB gene rearrangements and MYB-NFIB chimeric transcripts. Unlike common forms of TNBC, we found that AdCCs have a low mutation rate (0.27 non-silent mutations/Mb), lack mutations in TP53 and PIK3CA and display a heterogeneous constellation of known cancer genes affected by somatic mutations, including MYB, BRAF, FBXW7, SMARCA5, SF3B1 and FGFR2. MYB and TLN2 were affected by somatic mutations in two cases each. Akin to salivary gland AdCCs, breast AdCCs were found to harbour mutations targeting chromatin remodelling, cell adhesion, RNA biology, ubiquitination and canonical signalling pathway genes. We observed that, although breast AdCCs had rather simple genomes, they likely display intra-tumour genetic heterogeneity at diagnosis. Taken together, these findings demonstrate that the mutational burden and mutational repertoire of breast AdCCs are more similar to those of salivary gland AdCCs than to those of other types of TNBCs, emphasizing the importance of histological subtyping of TNBCs. Furthermore, our data provide direct evidence that AdCCs harbour a distinctive mutational landscape and genomic structure, irrespective of the disease site of origin.

    To evaluate radiological findings in patients submitted to surgical treatment for medullary breast cancer at Instituto Nacional de Cancer (INCa), Rio de Janeiro, RJ, Brazil, correlating them with histological results. A retrospective descriptive study was developed with patients submitted to surgery at INCa, in the period from January 1997 to December 2006, for identifying the presence of medullary breast carcinoma and analyzing radiological findings. Among 21,287 patients diagnosed with carcinoma, 76 (0.357%) had typical medullary breast carcinoma. The age range of these patients was 32-81 years (mean = 59.1 years). Mammography demonstrated lesions in 19 of these patients, 17 (89.5%) of them with masses, and 2 with focal asymmetry. Among the patients with masses, 15 (88.1%) presented with high density and 2 (11.9%) with isodensity. Twelve patients presented sonographic findings, 11 (91.6%) of them with hypoechoic masses, and one with an anechoic mass with areas of cystic degeneration. Nodular mass was the predominant radiological finding (89.5%), 88.1% of them corresponding to masses with high density and circumscribed margins. Despite the radiological characteristics of benignity, a solid, fast growing, highly dense mass with circumscribed margins should be further investigated to confirm the diagnosis. (author)

Methods: A prospective collaborative study was conducted by the Santa Casa de São Paulo and CTC-Center, on 540 breast lesions in women referred for percutaneous breast biopsy. Eighty-four carcinomas showing lesions on ultrasonography were included. These lesions were classified into four sonoelastographic scores, where scores of 1, 2, and 3 were considered false-negative, and a score of 4 was considered true-positive. Scores were compared against histopathologic results, which were divided into two groups, ie, soft lesions (group 1 and hard lesions (group 2. False-negative and true-positive results were also assessed for variation according to patient age and mean lesion diameter. Results: Of the 84 lesions studied, nine yielded false-negative results on sonoelastography and 75 yielded true-positive results. In terms of histopathologic classification, eight were assigned to group 1 and 76 to group 2. The chi-squared test showed a correlation between sonoelastographic scores and histopathologic lesion type. No statistically significant differences were observed according to patient age or largest lesion diameter. Conclusion: Our results revealed an association between sonoelastographic presentation of breast lesions and histology. False-negative results on sonoelastography were influenced by histologic type of lesion and not by lesion size or patient age. Keywords: ultrasound, breast, carcinoma, elastography

    Full Text Available Carcinoma of male breast is uncommon as it accounts for 0.7% of total breast cancer. The pathology of male breast cancer is remarkably similar to that of cancers seen in women. The same histological subtypes of invasive cancer are present, although papillary carcinomas (both invasive and in situ are more common and lobular carcinomas are less common. The predominant histological type, in males, as in females, reported in large series has been infiltrating ductal carcinoma with scattered reports of infiltrating lobular carcinoma, all of them of classical type except for a single case of pleomorphic infiltrating lobular carcinoma. Herein, we describe a case of pleomorphic lobular carcinoma occurring in male breast.

    Purpose: To report our experience on the detection of breast cancer (BC) through guided radiosurgical biopsies (GRSB) in the Gynecology Department of the Hospital Aeronautico Central (SGHAC). Materials and method: We retrospectively analyzed 622 GRSBs performed at the SGHAC between 1 January 1995 and 31 December 2004. We took into account single or associated lesions found in mammograms, which we subdivided into four types: 1) Non-palpable mammographic nodules; 2) Microcalcifications; 3) Structural distortions; 4) Mammographic asymmetries. Results: We found 332 non-palpable nodules (53.4%), 214 microcalcifications (34.4%), 40 structural distortions (6.4%), and 36 mammographic asymmetries (5.8%). Out of the 622 GRSBs performed during the above period, 152 BCs were diagnosed, that is, an incidence of 24.4% detected through this method. Out of the 152 BCs, 110 (72.4%) were invasive and 42 (27.6%) were noninvasive. Conclusions: Although 24.4% of BCs were identified through GRSBs, our tea m considers this to be the standard method for early detection of breast cancer. (author) [es

    Objective: To analyze the mammographic features of breast carcinoma and the correlation between the mammographic and pathologic findings. Methods: A prospective study of 397 consecutive mammograms in patients with breast carcinoma, including infiltrating ductal carcinoma (IDC, n=297), ductal carcinoma in situ (DCIS) and DCIS associated with small invasive foci (n=38), mucinous carcinoma (n=21), medullary carcinoma (n=22) and invasive lobular carcinoma (n=19), was performed to determine the correlations between the mammographic and pathologic findings. Results: (1) Microcalcifications appeared in 170 cases (42.8%), a mass in 258 cases (65.0%), and distortion in 33 cases (8.3%), respectively. (2) Microcalcifications were more commonly associated with DCIS and IDC (χ 2 =30.90, P 2 =30.87, P 2 =27.40, P 2 =6.22, P 2 =7.19, P < 0.01). Conclusion: The common features of breast carcinoma in mammography were microcalcifications, microcalcifications with a mass, a mass, and distortion IDC was the commonest in breast carcinoma, and could be considered when mammographic malignant features above mentioned were found except the appearance of microcalcifications alone, which was firstly suggestive of DCIS. A mass also appeared in medullary and mucinous carcinoma, and distortion appeared in invasive lobular carcinoma

    Genetic abnormalities in microenvironmental tissues with subsequent alterations of reciprocal interactions between epithelial and mesenchymal cells play a key role in the breast carcinogenesis. Although a few reports have demonstrated abnormal fibroblastic functions in normal-appearing fibroblasts taken from the skins of breast cancer patients, the genetic basis of this phenomenon and its implication for carcinogenesis are unexplored. We analyzed 12 mastectomy specimens showing invasive ductal carcinomas. In each case, morphologically normal epidermis and dermis, carcinoma, normal stroma close to carcinoma, and stroma at a distant from carcinoma were microdissected. Metastatic-free lymphatic tissues from lymph nodes served as a control. Using PCR, DNA extracts were examined with 11 microsatellite markers known for a high frequency of allelic imbalances in breast cancer. Losses of heterozygosity and/or microsatellite instability were detected in 83% of the skin samples occurring either concurrently with or independently from the cancerous tissues. In 80% of these cases at least one microsatellite marker displayed loss of heterozygosity or microsatellite instability in the skin, which was absent in carcinoma. A total of 41% of samples showed alterations of certain loci observed exclusively in the carcinoma but not in the skin compartments. Our study suggests that breast cancer is not just a localized genetic disorder, but rather part of a larger field of genetic alterations/instabilities affecting multiple cell populations in the organ with various cellular elements, ultimately contributing to the manifestation of the more 'localized' carcinoma. These data indicate that more global assessment of tumor micro- and macro-environment is crucial for our understanding of breast carcinogenesis.

  14. An unusual case of invasive papillary carcinoma of the breast

    Full Text Available Invasive papillary carcinoma is a rare variant of breast cancer. We report an unusual case of invasive papillary carcinoma of the breast with high nuclear grade, brisk mitosis, necrosis, extensive apocrine differentiation, and intense lymphoplasmacytic infiltrate; additionally triple-negativity for estrogen and progesterone receptors and Her2 neu. The patient underwent modified radical mastectomy and adjuvant chemotherapy. But, it was a node negative breast carcinoma. Increasing the awareness of this clinicopathologic entity would be helpful in avoiding overtreatment of patients with this cancer even if the tumor has negative morphological and immunohistochemical prognosticators.

    Purpose. - To report characteristics and outcome of breast cancer after irradiation for Hodgkin lymphoma with special focus on breast conservation surgery. Patients and methods. - Medical records of 72 women who developed either ductal carcinoma in situ or stage I-III invasive carcinoma of the breast after Hodgkin lymphoma between 1978 and 2009 were retrospectively reviewed. Results. - Median age at Hodgkin lymphoma diagnosis was 23 years old. Median total dose received by the mediastinum was 40 Gy, mostly by a mantle field technique. Breast cancer occurred after a median time interval of 21 years. Ductal invasive carcinoma and ductal carcinoma in situ represented respectively 71% and 19% of the cases. Locoregional treatment for breast cancer consisted of mastectomy with or without radiotherapy in 39 patients and of lumpectomy with or without adjuvant radiotherapy in 32 patients. The isocentric lateral decubitus radiation technique was used in 17 patients after breast conserving surgery (57%). With a median follow-up of 7 years, 5-year overall survival rate and locoregional control rate were respectively 74.5% and 82% for invasive carcinoma and 100% and 92% for in situ carcinoma. Thirteen patients died of progressive breast cancer and contralateral breast cancer was diagnosed in ten patients (14%). Conclusions. - Breast conserving treatment can be an option for breast cancers that occur after Hodgkin lymphoma despite prior thoracic irradiation. It should consist of lumpectomy and adjuvant breast radiotherapy with use of adequate techniques, such as the lateral decubitus isocentric position. (authors)

    Background: Carcinoma breast is most common cancer and the leading cause of cancer related deaths in women, with a multifactorial aetiology. This case control study was aimed at studying the possible link of body fat with the pathogenesis of carcinoma breast. Methods: A case control study extending over a period of two years (2015-2016) was conducted in which the body size and shape of 56 carcinoma breast cases was studied against 168 controls who had no breast disease. Results: Fifty-six women suffering from carcinoma breast had a higher BMI and fat distributed in the abdominal area A high BMI was found to be protective in pre-menopausal women (OR= 0.14 by; 95% CI: 0.02–0.77) while it was a risk factor in post-menopausal women (OR=2.39 by; 95% CI: 1.02–5.55). Waist-to-hip ratio (WHR) of ≥0.9 was associated with an increased risk of carcinoma breast compared to WHR ≤0.8 (OR=3.857 by; 95% CI: 0.875–17.05). Conclusion: the results show there is an increased risk of carcinoma breast in women having more fat cantered around the abdomen. (author)

    Breast cancer in men is uncommon, accounting for cancers. Even though lobular structures are quite infrequent in the male breast, rare cases of invasive lobular breast carcinoma have been described, representing 1-2% of all breast cancers in men. Risk factors include undescended testes, congenital inguinal hernia, orchiectomy, orchitis, testicular injury, infertility and Klinefelter's syndrome, previous thoracic radiotherapy, alterations of the oestrogen-testosterone ratio and familial history (BRCA 2 and 1). The authors present a case of a 52-year-old man with no relevant predisposing factors to breast cancer, who presented with a painless, firm nodule, fixed to the nipple on the left breast, associated with nipple retraction and ulceration, and fully characterised by mammogram and ultrasound. Histopathological and immunohistochemical analysis revealed the diagnosis of invasive lobular breast carcinoma and the patient underwent left radical mastectomy, followed by adjuvant chemotherapy, radiotherapy and hormonotherapy. A brief review of the literature is presented. 2016 BMJ Publishing Group Ltd.

    Secretory carcinoma is a rare low-grade breast carcinoma, initially termed juvenile breast cancer, but it is now known to occur in adults of both sexes. It is the only epithelial tumor of the breast with a balanced translocation, t(12;15), that creates an ETV6-NTRK3 gene translocation. In this paper, a 19-year-old male patient has had a right breast mass for 9 years which suddenly increased in size with no evidence of palpable axillary lymph nodes. The mass was excised for frozen section and was diagnosed as malignant growth for simple mastectomy. Microscopic examination revealed the classical features of secretory carcinoma. The tumor cells were positive for EMA and S-100 protein and focally positive for cytokeratin and ER but negative for progesterone receptor, CD34, and CEA. Four months later the patient developed ipsilateral axillary lymph node enlargement, with lymph node metastases in five of the dissected 19 lymph nodes. The patient was treated with six courses of chemotherapy and radiotherapy. Conclusion. Though considered an indolent neoplasm, secretory carcinoma does metastasize to lymph nodes. Surgery in the form of mastectomy with axillary clearance is the treatment of choice. This paper includes a rare case report of secretory carcinoma in young male patient, with axillary lymph node metastasis in spite of the indolent nature that this tumor is known to display

    Inflammatory breast carcinoma (IBC) diagnosis is usually based in the presence of typical clinical symptoms (redness and edema in more than 2/3 of the breast), which are not always associated with pathologic characteristics (subdermal lymphatics involvement). Whether exclusively pathologic findings without clinical symptoms are sufficient for IBC diagnosis remains controversial. A retrospective analysis of 163 clinically diagnosed IBC (CIC) either with dermal lymphatics invasion or not, was compared with another group of 99 patients with dermal lymphatics invasion without clinical symptoms (occult inflammatory carcinoma) (OIC). The following clinical and pathological characteristics have been analyzed and compared: age, menopausal status, clinical axillar node involvement, symptoms duration before diagnosis, grade, estrogen receptors, presence of metastases at diagnosis, local recurrence, metastasic dissemination, disease-free (DFS) and overall survival (OS). Median age was younger in CIC (52.3 vs. 63.8 years; p < 0.001). Symptom duration before diagnosis were significantly shorter in CIC (3.4 vs. 6.8 months: p < 0.0001). Visceral (36.2% vs. 17.2%; p = 0.001) and brain metastases (7.4% vs. 1%; p = 0.02) was significantly more frequent in CIC. Negative estrogen receptors were more frequent in CIC (34.9% vs. 65.1%: p < 0.004). Five-years DFS (25.6 vs. 51.6%; p < 0.0001) and OS (28.6 vs. 40%; p < 0.05) were shorter in CIC. CIC (regardless of subdermal lymphatics involvement) must be clearly differentiated from OIC. Prognosis of CIC patients is poorer, so this two entities should be clearly differentiated when therepeutic results are reported.

    The objective of this study was to analyze the incidence and treatment options of occult cancer or atypical lesions found in the histopathological examination of reduction mammoplasty (RM) specimens. The role of preoperative mammography and systematic histopathological examination are discussed. We performed a retrospective single-center database review of all patients who underwent a RM between January 2005 and December 2014. Preoperative examination, histopathological findings and follow-up were documented. A total of 1045 patients underwent RM, of which 97% were bilateral (1021). All patients received a mammography and routine clinical examination to exclude cancer preoperatively. The overall mean patient age was 40.2 years (14.2-73.4). A total of 19 patients (1.18%) had significant histopathological findings, all of whom were over 40 years of age. There were 4 incidental carcinomas (0.38%), of which 2 were DCIS (0.19%) and 2 invasive ductal carcinomas (0.19%). Incidence of postoperative diagnosis of occult breast cancer in RM specimens remains low, but poses significant therapeutic challenges. While emphasis should lay on preoperative diagnostics, routine histological analysis of RM specimens is recommended.

    AIM: To document the breast imaging findings of women with BRCA1 and BRCA2-associated breast carcinoma. MATERIALS AND METHODS: Family history clinic records identified 18 BRCA1 and 10 BRCA2 cases who collectively were diagnosed with 27 invasive breast carcinomas and four ductal carcinoma in situ (DCIS) lesions. All underwent pre-operative imaging (29 mammogram and 22 ultrasound examinations). All invasive BRCA-associated breast carcinoma cases were compared with age-matched cases of sporadic breast carcinoma. RESULTS: Within the BRCA cases the age range was 26-62 years, mean 36 years. Two mammograms were normal and 27 (93%) abnormal. The most common mammographic features were defined mass (63%) and microcalcifications (37%). Thirty-four percent of women had a dense mammographic pattern, 59% mixed and 7% fatty. Ultrasound was performed in 22 patients and in 21 (95%) indicated a mass. This was classified as benign in 24%, indeterminate in 29% and malignant in 48%. Mammograms of BRCA1-associated carcinomas more frequently showed a defined mass compared with BRCA2-associated carcinomas, 72 versus 36% (73% control group) whilst mammograms of BRCA2-associated carcinomas more frequently showed microcalcification, 73 versus 12% (8% control group; p<0.001). Thirty-six percent of the BRCA2-associated carcinomas were pure DCIS while none of the BRCA1 associated carcinomas were pure DCIS (p=0.004). Of those patients undergoing regular mammographic screening, 100% of BRCA2-associated carcinomas were detected compared with 75% of BRCA1-associated carcinomas. CONCLUSION: These data suggest that the imaging findings of BRCA1 and BRCA2-associated carcinomas differ from each other and from age-matched cases of sporadic breast carcinoma.

    Recently, growing interest in the potential link between metabolic disorders (i.e., diabetes, obesity, metabolic syndrome) and breast cancer has mounted, including studies which indicate that diabetic/hyperinsulinemic women have a significantly higher risk of bearing breast tumors that are more aggressive and associated with higher death rates. Insulin signaling is regarded as a major contributor to this phenomenon; much less is known about the role of heparan sulfate-degrading enzyme heparanase in the link between metabolic disorders and cancer. In the present study we analyzed clinical samples of breast carcinoma derived from diabetic/non-diabetic patients, and investigated effects of heparanase on insulin signaling in breast carcinoma cell lines, as well as insulin-driven growth of breast tumor cells. We demonstrate that heparanase activity leads to enhanced insulin signaling and activation of downstream tumor-promoting pathways in breast carcinoma cells. In agreement, heparanase enhances insulin-induced proliferation of breast tumor cells in vitro. Moreover, analyzing clinical data from diabetic breast carcinoma patients, we found that concurrent presence of both diabetic state and heparanase in tumor tissue (as opposed to either condition alone) was associated with more aggressive phenotype of breast tumors in the patient cohort analyzed in our study (two-sided Fisher's exact test; p=0.04). Our findings highlight the emerging role of heparanase in powering effect of hyperinsulinemic state on breast tumorigenesis and imply that heparanase targeting, which is now under intensive development/clinical testing, could be particularly efficient in a growing fraction of breast carcinoma patients suffering from metabolic disorders.

    1990-12-01

    100 cases of breast carcinoma were studied with lectin affinitive histochemistry technology. The result showed that Ricinus comunis agglutinin (RCA1) was located in almost all intraductal carcinomas but one, while the positive rates in the other types were obviously low (P less than 0.05). The positive rate of Ulex europaeus agglutinin-I (UEA1) in well-differentiated types was higher than that in poorly-differentiated ones (P less than 0.05). The location of Peanut agglutinin (PNA), Bandeiraea Simplicifolia (BSL) and UEA1 in breast carcinomas exhibited some regularity and it might be useful in understanding the differentiation of breast carcinomas. No relationship between changes of the eight lectins and metastases in axillary lymph nodes was observed, but the authors considered that PNA-affinitive histochemistry was beneficial to the detection of micrometastases in lymph nodes.

    Invasive lobular carcinoma of the breast is the second most common type of primary breast cancer, accounting for 8-14% of cases, but is often difficult to diagnose early. It typically shows a diffuse pattern of infiltration within the breast, resulting in a variety of often subtle radiological appearances. A similar infiltrative pattern is seen in its metastatic form, with involvement of the gastrointestinal tract, peritoneum, retroperitoneum, bone marrow, meninges and uterus occurring more frequently than with the more common infiltrating ductal carcinoma of the breast. This pictorial essay illustrates the spectrum of radiological appearances which may be encountered with both primary and secondary lobular carcinoma. Harake, M.D.J., Maxwell, A.J. and Sukumar, S.A.

    Despite the advances in mammography techniques, it still has a number of limitations. It is estimated that about 10 to 25% of lesions are overlooked in mammograms out of which about two thirds are detected retrospectively by radiologists and oncologists. Causes of missed breast cancer on mammography can be secondary to many factors including those related to the patient (whether inherent or acquired), the nature of the malignant mass itself, poor mammographic techniques, provider factors or interpretive skills of radiologists and oncologists (including perception and interpretation errors). Aim of Work: The aim of this study is to investigate the aforementioned factors hindering early breast cancer detection and in turn lowering mammographic sensitivity and to outline the major guidelines to overcome these factors aiming to an optimum mammographic examination and interpretation by radiologists and oncologists. Subject and Methods: We conducted this multicenter study over a two-year interval. We included 152 histo-pathological proven breast carcinomas that were initially missed on mammography. The cases were subjected to mammography, complementary US, MRI and digital mammography in some cases and all cases were histo-pathologically proven either by FNAB, CNB or open biopsy. Results: Revision of the pathological specimens of these 152 cases revealed 121 infiltrating ductal carcinomas, 2 lobular, 4 mucinous, 14 inflammatory carcinomas, 6 carcinomas in situ (3 of which were intracystic), 2 intraductal papillary carcinomas and 3 cases with Paget's disease of the nipple. In analyzing the causes responsible for misdiagnosis of these carcinomas we classified them into 4 causative factors; patient, tumor, technical or provider factors. Tumor factors were the most commonly encountered, accounting for 44. I %, while provider factors were the least commonly encountered in 14.5%. Carcino- mas were detected using several individual or combined complementary techniques. These

    Stromal fibroblasts actively participate in normal mammary gland homeostasis and in breast carcinoma growth and progression by secreting paracrine factors; however, little is known about the identity of paracrine mediators in individual patients. The purpose of this study was to characterize paracrine signaling pathways between breast carcinoma cells and breast carcinoma-associated fibroblasts (CAF) or normal mammary fibroblasts (NF), respectively. CAF and NF were isolated from breast carcinoma tissue samples and adjacent normal mammary gland tissue of 28 patients. The fibroblasts were grown in 3D collagen gel co-culture with T47D human breast carcinoma cells and T47D cell growth was measured. CAF stimulated T47D cell growth to a significantly greater degree than NF. We detected a considerable inter-individual heterogeneity of paracrine interactions but identified FGF2, HB-EGF, heparanase-1 and SDF1 as factors that were consistently responsible for the activity of carcinoma-associated fibroblasts. CAF from low-grade but not high-grade carcinomas required insulin-like growth factor 1 and transforming growth factor beta 1 to stimulate carcinoma growth. Paradoxically, blocking of membrane-type 1 matrix metalloprotease stimulated T47D cell growth in co-culture with NF. The results were largely mirrored by treating the fibroblasts with siRNA oligonucleotides prior to co-culture, implicating the fibroblasts as principal production site for the secreted mediators. In summary, we identify a paracrine signaling network with inter-individual commonalities and differences. These findings have significant implications for the design of stroma-targeted therapies.

    2015-10-01

    Acinic cell carcinomas (AcCC) of the breast have been reported to constitute the breast counterpart of salivary gland AcCCs, based on the similarities of their histological and immunohistochemical features. Breast AcCC is a vanishingly rare form of triple-negative breast cancer (TNBC). Recent studies have demonstrated that in TNBCs, the two driver genes most frequently mutated are TP53 (82%) and PIK3CA (10%). We sought to define whether breast AcCCs would harbour TP53 and PIK3CA somatic mutations, and if so, whether these would be present in salivary gland AcCCs. Sanger sequencing of the entire coding region of TP53 and of PIK3CA hotspot mutation sites of 10 breast and 20 salivary gland microdissected AcCCs revealed eight TP53 (80%) and one PIK3CA (10%) somatic mutations in breast AcCCs. No somatic mutations affecting these genes were found in the 20 salivary gland AcCCs analysed. Our findings demonstrate that breast AcCCs display TP53 and PIK3CA mutations at frequencies similar to those of common types of TNBCs, whereas these genes appear not to be altered in salivary gland AcCCs, suggesting that despite their similar histological appearances, AcCCs of the breast and salivary glands probably constitute unrelated diseases. © 2015 John Wiley & Sons Ltd.

    Full Text Available Breast metastases from distant carcinoma are infrequent, and cervix carcinoma is rarely the primary lesion. We describe the first case of a cervical squamous cell carcinoma with breast metastasis mimicking an inflammatory breast cancer in a 74-year-old woman. Seventeen months after the treatment of a primary tumor, the patient developed breast lesions looking like an inflammatory breast tumor. After a 1-year delay due to the patient’s refusal, pathological examination and immunohistochemistry confirmed the diagnosis of breast metastasis from a poorly differentiated squamous cell carcinoma. The volume of the breast was huge, associated with axillary lymphadenopathies and multiple lung metastases. Despite platinum-based chemotherapy, the disease progressed and the patient died rapidly, 3 months after the first chemotherapy cycle and 15 months after the first mammary symptoms. We review the literature concerning breast metastases from gynecologic cancers and, particularly, from cervical squamous cell carcinoma. Differential diagnosis of such lesions may be problematic but is essential to avoid unnecessary mutilating surgery and to institute the appropriate systemic therapy. The prognosis is poor.

    2011-08-01

    We describe a set of web-based calculators, available at http://www.CancerMath.net , which estimate the risk of breast carcinoma death, the reduction in life expectancy, and the impact of various adjuvant treatment choices. The published SNAP method of the binary biological model of cancer metastasis uses information on tumor size, nodal status, and other prognostic factors to accurately estimate of breast cancer lethality at 15 years after diagnosis. By combining these 15-year lethality estimates with data on the breast cancer hazard function, breast cancer lethality can be estimated at each of the 15 years after diagnosis. A web-based calculator was then created to visualize the estimated lethality with and without a range of adjuvant therapy options at any of the 15 years after diagnosis, and enable conditional survival calculations. NIH population data was used to estimate non-breast-cancer chance of death. The accuracy of the calculators was tested against two large breast carcinoma datasets: 7,907 patients seen at two academic hospitals and 362,491 patients from the SEER national dataset. The calculators were found to be highly accurate and specific, as seen by their capacity for stratifying patients into groups differing by as little as a 2% risk of death, and accurately accounting for nodal status, histology, grade, age, and hormone receptor status. Our breast carcinoma calculators provide accurate and useful estimates of the risk of death, which can aid in analysis of the various adjuvant therapy options available to each patient.

    Full Text Available The role of adhesion molecules is very important both in the activation of carcinogenesis and in the differentiation of subtypes of breast carcinoma, aiding in diagnosis, prognosis and therapeutic choice in these tumors. Therefore, understanding the functions and interrelationships among these molecules is crucial to the pathologist, who often uses these factors as a resource to differentiate tumors and further classify them according to a molecular point of view. Our goal is to describe the applicability and the difficulties encountered by the pathologist in the diagnosis of breast carcinoma, discussing the most commonly used markers of adhesion in routine analyses.

  20. Solid papillary carcinoma of the breast: A review

    Directory of Open Access Journals (Sweden)

    ZACKARIAH VK CLEMENT

    2017-01-01

    Full Text Available Solid papillary carcinoma of breast is a low-grade tumour originating in the ductal epithelium. It is commonly seen in post-menopausal women and account for <1% of all breast cancers. Patients can be asymptomatic, have nipple discharge or present with abnormal mammographic findings. Despite of some radiological features solid papillary carcinoma cannot be accurately diagnosed on imaging alone. The most important characteristic of this tumour is its behaviour and interesting pathological feature of lack of myoepithelial cells at the periphery. Its diagnosis can be challenging and its management is still debated. Management varies from breast conserving surgery to mastectomy. Currently there is no evidence to support the role of sentinel lymph node biopsy, radiotherapy and hormonal therapy. Therefore, accurate diagnosis with adequate local excision with breast conserving surgery is the optimal treatment.

    2015-09-01

    Basaloid carcinoma of the breast (BCB) is a rare, triple-negative aggressive primary breast tumor that can closely mimic cutaneous basal cell carcinoma (BCC), neuroendocrine tumors, adnexal neoplasms, and other primary breast tumors. Accurate diagnosis of this tumor is critical for appropriate clinical management. We add to the literature 2 female patients with BCB presenting with a nipple mass. Histopathologic findings from both patients showed dermal nests and cords of atypical basaloid cells with epidermal involvement, closely resembling cutaneous BCC. A panel of immunohistochemical stains, including the novel use of CK17, is essential for differentiating BCB from mimickers. BCB is a rare primary breast tumor that follows an aggressive clinical course and closely mimics many basaloid neoplasms, including cutaneous BCC clinicopathologically. Increased awareness of BCB among dermatologists and dermatopathologists is critical for accurate diagnosis and patient care.

    Full Text Available A 71-year-old woman, previously treated for malignant lymphoma, was admitted to our hospital with a tumor in the right breast. The tumor size was 2.0 cm in diameter, and the borderline was unclear. The core needle biopsy material revealed an invasive adenocarcinoma with metaplastic change. Right mastectomy and sentinel lymph node biopsy was performed. Histologically, the tumor was composed of mucus-secreting, epidermoid, and intermediate cells. These findings confirmed the diagnosis as mucoepidermoid carcinoma (MEC of the breast. MEC is more frequently observed in the salivary glands and occurs rarely in the breast, with an incidence of approximately 0.3% of all breast cancers. Because of the rarity of the disease, the clinicopathological features and clinical outcome have not been fully investigated. The relationship between MEC of the breast and lymphoma are unclear. Here we report a rare case of MEC of the breast.

    Pregnancy associated breast carcinoma requires making judicious use of all diagnostic modalities and the therapeutic options of surgery, irradiation, chemotherapy and hormonal therapy to enhance survival rates. Individualization of treatment for each patient is the key to success. The effects on future fertility, the time interval before next conception, and whether to breast feed or not are all well-documented. A multidisciplinary coordinated team approach to this ultimate challenge of patient care will prove fruitful. (author)

    2014-01-01

    Neuroendocrine carcinoma of the breast (NCB) is a fairly recent diagnostic entity added by WHO in 2003. Since then, studies have indicated that NCB potentially displays a worse prognosis than invasive ductal carcinoma. However, due to a lack of standard use of immunohistochemical staining...... for neuroendocrine markers and the fact that NCB may only show slight neuroendocrine morphology that can easily be overlooked, NCB is often underdiagnosed. Consequently, there is a need for fast and reliable detection method for NCB. Here, we take a first step toward finding an easy way of identifying NCB...... by investigating the usefulness of tissue microarray (TMA) analysis as a screening tool. We present our findings with regard to sensitivity and specificity compared with whole-mount sections. The material consists of 240 cases of breast cancer divided into 20 TMA blocks that were all immunohistochemically stained...

RESULTS The patients were regularly followed up and at the end of the study 35 (70% of the patients were doing well. 4(8% of the patients developed distant metastasis and 3 (6% of the patients developing local recurrence. 8 (16% of the patients were lost follow up. CONCLUSION About half of the cases presenting with breast cancer are in locally advanced stages. Multimodality therapy is the effective treatment of locally advanced carcinoma of breast. Breast cancer management is a challenge and improvement in therapies are needed for disease-free interval and overall survival period.

    Primary carcinoma with osteoclast-like giant cells is a very rare tumour of the female breast. The clinical course, histological, immunohistochemical and ultrastructural features of 61 cases of invasive duct carcinoma with osteoclast-like multinucleated giant cells (OMGCs) are reviewed and a new...... in the literature have shown that 86% of patients with these tumours are still alive after 5 years. Histologically, these tumours are invasive ductal carcinomas with OMGCs next to the neoplastic glands and within their lumen. Signs of recent and past haemorrhage are ubiquitously present in the highly vascularized...

    Adenoid cystic carcinoma of the breast is a rare histological type of triple-negative breast cancer with an indolent clinical behavior, often driven by the MYB-NFIB fusion gene. Here we sought to define the repertoire of somatic genetic alterations in two adenoid cystic carcinomas associated with high-grade triple-negative breast cancer. The different components of each case were subjected to copy number profiling and massively parallel sequencing targeting all exons and selected regulatory and intronic regions of 488 genes. Reverse transcription PCR and fluorescence in situ hybridization were employed to investigate the presence of the MYB-NFIB translocation. The MYB-NFIB fusion gene was detected in both adenoid cystic carcinomas and their associated high-grade triple-negative breast cancer components. Although the distinct components of both cases displayed similar patterns of gene copy number alterations, massively parallel sequencing analysis revealed intratumor genetic heterogeneity. In case 1, progression from the trabecular adenoid cystic carcinoma to the high-grade triple-negative breast cancer was found to involve clonal shifts with enrichment of mutations affecting EP300, NOTCH1, ERBB2 and FGFR1 in the high-grade triple-negative breast cancer. In case 2, a clonal KMT2C mutation was present in the cribriform adenoid cystic carcinoma, solid adenoid cystic carcinoma and high-grade triple-negative breast cancer components, whereas a mutation affecting MYB was present only in the solid and high-grade triple-negative breast cancer areas and additional three mutations targeting STAG2, KDM6A and CDK12 were restricted to the high-grade triple-negative breast cancer. In conclusion, adenoid cystic carcinomas of the breast with high-grade transformation are underpinned by the MYB-NFIB fusion gene and, akin to other forms of cancer, may be constituted by a mosaic of cancer cell clones at diagnosis. The progression from adenoid cystic carcinoma to high-grade triple

    Breast carcinoma exceptionally leads to metastatic linitis plastica. Distinguishing a breast cancer metastasis to the stomach from a primary gastric cancer on the basis of clinical and radiological signs is very challenging. Thanks to being cognizant of the previous history of invasive lobular carcinoma and the gastric biopsy followed by immunohistochemical analysis, gastric metastasis can be diagnosed. Despite the use of chemotherapy and hormonal therapy, gastric metastasis remains often associated with poor prognosis. We present a case where gastric biopsy allowed a metastatic breast cancer to the stomach to be diagnosed and we discuss its clinical, diagnostic, pathological and therapeutic particularities.

    Metastatic tumors to the jawbones are an infrequent but not rare phenomenon. The most common site of distant primary tumor metastasis to the jaw bones is the breast. The clinical signs and symptoms, and radiographic appearance of these lesions can be quite variable. In this report, an invasive ductal carcinoma of the breast that metastasized to the whole mandible is presented. The patient's medical history revealed that she had undergone a modified radical mastectomy on the right breast eight years ago.

    Glycogen-rich carcinoma of the breast is a rare histological subtype of breast cancer, usually reported to have poor prognosis. We present the case of a 59-year-old woman who underwent a mastectomy for a 3.5 cm clinically palpable left breast carcinoma, originally diagnosed as fibroadenoma on a screening mammogram four years before presentation. Diagnosis of clear cell carcinoma was based on certain histological characteristics of the tumour and immunohistochemical analysis (PAS staining, keratins AE1/AE3, EMA, cytokeratin 7, cytokeratin 20, melanosomes, vimentin, Chromogranin, Synaptophysin, S-100, SMA). No lymph node metastasis was found and as the tumour was ER positive and PgR negative, patient was treated only with an aromatase inhibitor upfront and remains free of disease 48 months now since operation. Glycogen-rich clear cell carcinoma of the breast is a rare tumor, its clinical behavior reported to be rather aggressive so far, might varies depending on special characteristics such as low grade and strongly positive ER expression.

    This study aims to evaluate the sensibility and specificity of MRI in the detection and size measuring of residual breast cancer in patients treated with neoadjuvant chemotherapy before surgery. This is a retrospective study of 32 women, who underwent breast MRI before and after neoadjuvant treatment. MRI has been confronted to surgical pathology results. The sensibility of MRI to assess pathologic Complete Response (no invasive residual tumor) was excellent (100%) but the specificity was low (55,5%). There was no false negative case and four false positive cases (Two ductal carcinomas in situ and two scars-like fibrosis). When MRI outcomes were compared with the presence or absence of invasive or in situ residual carcinoma, only one false negative case was noticed (one "in situ" residual tumor). The correlation between tumor size measured by MRI and histopathology was low (r=0,32). Underestimations of tumor size were due to non-continuous tumor regression or invasive lobular carcinoma or association of invasive carcinoma and intra ductal breast cancer. Over estimations of tumor size were due to chemotherapy-induced changes. MRI is a sensitive but poorly specific method to assess the pathological complete response after neoadjuvant chemotherapy. Estimation of tumor size and detection of isolated residual in situ carcinoma are fare. Therefore, surgical intervention remains necessary whatever the MRI outcomes.

    The present study was planned to assess the relationship of palmar dermatoglyphic patterns of hands in women with breast cancer and or at risk for developing breast cancer. This study was conducted on 100 histopathologically confirmed breast cancer patients in women and their digital dermatoglyphic patterns were studied to assess their association with the type and onset of breast cancer. Simultaneously 100 age-matched controls were also selected with no self or familial history of a diagnosed breast cancer and the observations were recorded. The differences of qualitative (dermatoglyphic patterns) data were tested for their significance using the chi-square test, and Student's t-test was used for quantitative (ridge counts and pattern intensity index) data analysis. The results of the study indicated statistically significant changes in finger ridge count and fingertip pattern in cases of carcinoma breast as compared to the control group. Palmar dermatoglyphics is simple, inexpensive, anatomical and non-invasive and may be used as a reliable indicator for screening of high-risk population in developing country like India, for early detection and early therapy, thus reducing the morbidity and mortality in cases of carcinoma breast.

    Full Text Available Malignant mesothelioma is an uncommon tumor with strong association with asbestos exposure. Few cases of malignant pleural mesothelioma metastatic to the female breast have been reported. Herein, we presented, for the first time, a case of locally infiltrating malignant pleural mesothelioma forming a mass in the breast of a male as the first pathologically confirmed manifestation of the disease. Breast ultrasound revealed an irregular mass in the right breast which involves the pectoralis muscle. Breast core biopsy revealed a proliferation of neoplastic epithelioid cells mimicking an infiltrating pleomorphic lobular carcinoma. IHC studies showed the cells to be positive for calretinin, CK5/6, WT1, and CK7. The cells were negative for MOC-31, BerEp4, ER, and PR. A final diagnosis of malignant mesothelioma, epithelioid type, was rendered. This case demonstrates the importance of considering a broad differential diagnosis in the setting of atypical presentation with application of a panel of IHC markers.

    Acinic cell carcinoma is an indolent form of invasive breast cancer, whereas microglandular adenosis has been shown to be a neoplastic proliferation. Both entities display a triple-negative phenotype, and may give rise to and display somatic genomic alterations typical of high-grade triple-negative breast cancers. Here we report on a comparison of previously published data on eight carcinoma-associated microglandular adenosis and eight acinic cell carcinomas subjected to targeted massively parallel sequencing targeting all exons of 236 genes recurrently mutated in breast cancer and/or DNA repair-related. Somatic mutations, insertions/deletions and copy number alterations were detected using state-of-the-art bioinformatic algorithms. All cases were of triple-negative phenotype. A median of 4.5 (1–13) and 4.0 (1–7) non-synonymous somatic mutations per carcinoma-associated microglandular adenosis and acinic cell carcinoma were identified, respectively. TP53 was the sole highly recurrently mutated gene (75% in microglandular adenosis versus 88% in acinic cell carcinomas), and TP53 mutations were consistently coupled with loss of heterozygosity of the wild-type allele. Additional somatic mutations shared by both groups included those in BRCA1, PIK3CA and INPP4B. Recurrent (n=2) somatic mutations restricted to microglandular adenosis or acinic cell carcinomas included those affecting PTEN and MED12, or ERBB4, respectively. No significant differences in the repertoire of somatic mutations were detected between microglandular adenosis and acinic cell carcinomas, and between this group of lesions and 77 triple-negative carcinomas from The Cancer Genome Atlas. Microglandular adenosis and acinic cell carcinomas, however, were genetically distinct from estrogen receptor-positive and/or HER2-positive breast cancers from The Cancer Genome Atlas. Our findings support the contention that microglandular adenosis and acinic cell carcinoma are part of the same spectrum of lesions

    There have been some reports of coincidental presentation of breast carcinoma and phyllodes tumor in the same breast. Most of the cases were carcinoma that arose from a phyllodes tumor with a histologically identified transitional area, and they behaved less aggressively than the usually encountered carcinoma. Collision tumors are rare clinical entities in which two histologically distinct tumor types show involvement at the same site. The occurrence of these tumors in the breast is extremely rare. Here, we report a case of 45-year-old woman who had both invasive ductal carcinoma as the finding of inflammatory carcinoma and a malignant phyllodes tumor in the same breast. There was no evidence of a transitional area between the phyllodes tumor and the invasive ductal carcinoma. To our knowledge, this is the first report of a collision tumor of inflammatory breast carcinoma coincident with a malignant phyllodes tumor in same breast.

    Carcinoma in the ''empty breast'' in our experience is so common that we doubt Wolfe's conclusions in his classification of parenchymal patterns. Amongst patients over 60 years, almost 70% of carcinomas were situated in an ''empty'' parenchyma and they did not develop in a parechymal group above P1. Mammographically, the ''empty breast'' is the structureless fatty breast of older women after the menopause. Some authors believe that there is a lower incidence of carcinomas in this type of breast than in other types of parenchyma, such as those showing mastopathies. Our experience concerning carcinomas in involuted breasts is described. (orig.) [de

  7. Breast carcinoma with neuroendocrine features: a brief review

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Breast carcinoma with neuroendocrine features (BCNF is a rare entity that is defined by a neuroendocrine (NE architecture and cytomorphology combined with an immunohistochemical expression of chromogranin A or B and/or synaptophysin. According to the 2012 World Health Organization (WHO classification, they are classified into three subtypes: invasive breast carcinoma with NE differentiation, well-differentiated NE tumor, and poorly differentiated small cell carcinoma. BCNF are typically positive for the estrogen and progesterone receptor and negative for Her-2/ neu protein. The clinical features are not sufficiently specific to distinguish BCNF from other breast carcinomas. BCNF can mimic benign lesions on mammography, so the additional use of ultrasound or MRI can improve detection. Other imaging tests are useful to detect or rule out metastatic disease. Although standardized treatment guidelines have not yet been established, the mainstay of treatment for early BCNFs is surgery. Adjuvant treatment decisions should be individualized and should take into consideration the prognostic and predictive factors, clinical evidence and the patient’s overall health treatment preferences. Therapeutic options in the metastatic setting include surgery, chemotherapy, peptide receptor radionuclide therapy and molecular-targeted agents. These options are not mutually exclusive and are interchangeable.

  8. In situ identification of CD44+/CD24- cancer cells in primary human breast carcinomas.

    Directory of Open Access Journals (Sweden)

    Giuseppe Perrone

    Full Text Available Breast cancer cells with the CD44+/CD24- phenotype have been reported to be tumourigenic due to their enhanced capacity for cancer development and their self-renewal potential. The identification of human tumourigenic breast cancer cells in surgical samples has recently received increased attention due to the implications for prognosis and treatment, although limitations exist in the interpretation of these studies. To better identify the CD44+/CD24- cells in routine surgical specimens, 56 primary breast carcinoma cases were analysed by immunofluorescence and confocal microscopy, and the results were compared using flow cytometry analysis to correlate the amount and distribution of the CD44+/CD24- population with clinicopathological features. Using these methods, we showed that the breast carcinoma cells displayed four distinct sub-populations based on the expression pattern of CD44 and CD24. The CD44+/CD24- cells were found in 91% of breast tumours and constituted an average of 6.12% (range, 0.11%-21.23% of the tumour. A strong correlation was found between the percentage of CD44+/CD24- cells in primary tumours and distant metastasis development (p = 0.0001; in addition, there was an inverse significant association with ER and PGR status (p = 0.002 and p = 0.001, respectively. No relationship was evident with tumour size (T and regional lymph node (N status, differentiation grade, proliferative index or HER2 status. In a multivariate analysis, the percentage of CD44+/CD24- cancer cells was an independent factor related to metastasis development (p = 0.004. Our results indicate that confocal analysis of fluorescence-labelled breast cancer samples obtained at surgery is a reliable method to identify the CD44+/CD24- tumourigenic cell population, allowing for the stratification of breast cancer patients into two groups with substantially different relapse rates on the basis of CD44+/CD24- cell percentage.

    Joseph M Catanzaro

    2011-04-01

    Full Text Available Squamous cell carcinoma antigen (SCCA belongs to the serine protease inhibitor (Serpin family of proteins. Elevated expression of SCCA has been used as a biomarker for aggressive squamous cell carcinoma (SCC in cancers of the cervix, lung, head and neck, and liver. However, SCCA expression in breast cancer has not been investigated. Immunohistochemical analysis of SCCA expression was performed on tissue microarrays containing breast tumor tissues (n = 1,360 and normal breast epithelium (n = 124. SCCA expression was scored on a tiered scale (0-3 independently by two evaluators blind to the patient's clinical status. SCCA expression was observed in Grade I (0.3%, Grade II (2.5%, and Grade III (9.4% breast cancers (p<0.0001. Comparing tissues categorized into the three non-metastatic TNM stages, I-III, SCCA positivity was seen in 2.4% of Stage I cancers, 3.1% of Stage II cancers, and 8.6% of Stage III breast cancers (p = 0.0005. No positive staining was observed in normal/non-neoplastic breast tissue (0 out of 124. SCCA expression also correlated to estrogen receptor/progesterone receptor (ER/PR double-negative tumors (p = 0.0009. Compared to SCCA-negative patients, SCCA-positive patients had both a worse overall survival and recurrence-free survival (p<0.0001 and p<0.0001, respectively. This study shows that SCCA is associated with both advanced stage and high grade human breast carcinoma, and suggests the necessity to further explore the role of SCCA in breast cancer development and treatment.

  11. Malignant melanoma and breast carcinoma: a bidirectional correlation.

    Ho, W L

    2012-02-01

    BACKGROUND: Epidemiologic and genetic studies have suggested a bidirectional association between breast carcinoma (BC) and malignant melanoma (MM). OBSERVATION: We present a series of patients with MM and BC detected in our department within a span of 6 months, raising concerns for the high associations between the two malignancies. This led us to match the concordance of the two tumours in the National Irish Cancer Registry. CONCLUSION: The national figures provide evidence of a link between BC and MM. We recommend increased awareness among clinicians leading to more detailed surveillance of both second primary tumours. All MM patients with a family history of BC should be referred to a breast clinic. Women above the age of 40 with MM should undergo annual mammography and those less than 40 may be better evaluated with a breast MRI. All breast cancer patients should be made aware of the significance of changing moles and those with suspicious lesions referred to a dermatologist for evaluation.

    Squamous cell carcinoma of the oral cavity (OSCC) is a common cancer form with relatively low 5-year survival rates, due partially to late detection and lack of complementary molecular markers as targets for treatment. Molecular profiling of head and neck cancer has revealed biological similarities with basal-like breast and lung carcinoma. Recently, we showed that 16 genes were consistently altered in invasive breast tumors displaying varying degrees of aggressiveness. To extend our findings from breast cancer to another cancer type with similar characteristics, we performed an integrative analysis of transcriptomic and proteomic data to evaluate the prognostic significance of the 16 putative breast cancer-related biomarkers in OSCC using independent microarray datasets and immunohistochemistry. Predictive models for disease-specific (DSS) and/or overall survival (OS) were calculated for each marker using Cox proportional hazards models. We found that CBX2, SCUBE2, and STK32B protein expression were associated with important clinicopathological features for OSCC (peritumoral inflammatory infiltration, metastatic spread to the cervical lymph nodes, and tumor size). Consequently, SCUBE2 and STK32B are involved in the hedgehog signaling pathway which plays a pivotal role in metastasis and angiogenesis in cancer. In addition, CNTNAP2 and S100A8 protein expression were correlated with DSS and OS, respectively. Taken together, these candidates and the hedgehog signaling pathway may be putative targets for drug development and clinical management of OSCC patients

    Full Text Available Background: Calretinin (CR, a known mesothelial marker, is expressed in both epithelial and mesenchymal malignancies including breast cancer. Aims: We aimed to measure the frequency of CR expression in correlation with other clinicopathological parameters of different molecular subtypes of invasive breast carcinoma and to study its prognostic implications in this common cancer.Study Design: Tissue microarrays were constructed from 225 tissue samples of breast carcinoma cases. Subjects and Methods: Immunostaining for CR in addition to estrogen receptors, progesterone receptors, human epidermal growth factor receptor 2 (HER2, epidermal growth factor receptor, CK5/6, and Ki-67 for molecular subtyping. Statistical Analysis Used: Chi-square and Fisher's exact tests were done using SPSS 18.0 software (IBM Inc.. Survival data were analyzed using Kaplan–Meier test, Log-rank test, and Cox proportional hazard models. Results: Cases of invasive breast carcinomas with different grades were classified into 84 luminal A, 45 luminal B, 27 HER2 positive, 40 basal-like, and 29 unclassified. High CR expression was associated with tumors of high grade (P < 0.0001, high locoregional recurrence (P = 0.005, hormonal receptors negative, and high Ki-67 indices. They frequently display a basal-like phenotype (70%, P < 0.0001, HER2 (59.3%, and luminal B (33.3% tumors compared to luminal A (9.5% and unclassified subtypes (17.2%. Moreover, it is associated with poor overall patient survival (P = 0.034, but it does not affect disease-free survival. Conclusions: Calretinin could be a reliable predictor marker of adverse prognosis in breast cancer.

    Full Text Available Cells release vesicles to the extracellular environment with characteristic nucleic acid, protein, lipid, and glycan composition. Here we have isolated and characterized extracellular vesicles (EVs and total cell membranes (MBs from ovarian carcinoma OVMz cells. EVs were enriched in specific markers, including Tsg101, CD63, CD9, annexin-I, and MBs contained markers of cellular membrane compartments, including calnexin, GRASP65, GS28, LAMP-1, and L1CAM. The glycoprotein galectin-3 binding protein (LGALS3BP was strongly enriched in EVs and it contained sialylated complex N-glycans. Lectin blotting with a panel of lectins showed that EVs had specific glycosignatures relative to MBs. Furthermore, the presence of glycoproteins bearing complex N-glycans with α2,3-linked sialic acid, fucose, bisecting-GlcNAc and LacdiNAc structures, and O-glycans with the T-antigen were detected. The inhibition of N-glycosylation processing from high mannose to complex glycans using kifunensine caused changes in the composition of EVs and induced a decrease of several glycoproteins. In conclusion, the results showed that glycosignatures of EVs were specific and altered glycosylation within the cell affected the composition and/or dynamics of EVs release. Furthermore, the identified glycosignatures of EVs could provide novel biomarkers for ovarian cancer.

    2011-01-01

    For years, the treatment for invasive lobular carcinoma (ILC) has been mastectomy secondary to the lack of studies investigating the efficacy of breast conservation therapy on patients afflicted with ILC and due to the lack of long-term follow up investigating locoregional recurrence in this patient population. In this article we report the clinical course of a patient diagnosed with ILC. We describe the case of a 50-year-old woman with stage IIB (T2N1M0) ER/PR positive right breast ILC who underwent a right modified radical mastectomy, postoperative chemotherapy, a prophylactic left simple mastectomy with bilateral breast reconstruction and tamoxifen. Approximately 12 years later, she presented with a deflated breast implant and recurrent breast cancer with metastatic spread. She received palliative radiotherapy then palliative chemotherapy. Unfortunately, she succumbed to the cancer less than a year after being diagnosed with metastatic disease. This may be the first case report of a ruptured breast implant presenting at the same time as the diagnosis of recurrent breast cancer

    Purpose/Objective: To evaluate the place of conservative treatment in invasive lobular carcinoma. Materials and Methods: From 01/01/85 to 31/12/92, 109 patients with clinically and mammographically unifocal invasive lobular carcinoma of the breast (T<35 mm) underwent tumorectomy, axillary dissection and radiation therapy; they received an adjuvant treatment in case of nodal involvement (n = 31) or lack of estrogen and progesterone receptors (n = 16). The entire breast received 50 Gy with a systematic boost of 10 Gy. Results: With a median follow-up of 86 months, we observed 11 isolated local recurrences (T0 = (3(19)), T1 = (6(41)), T2 = (2(49))), 7 local recurrences associated with metastases (T1 = (3(41)), T2 = (4(49))) and 7 cases of metastatic diseases (T1 = (4(41)), T2 = (3(49))). Among the 11 patients with isolated local recurrence, 7 are alive with no evidence of disease after salvage mastectomy. Nine contro-lateral breast cancers occurred, 2 synchronous and 7 metachronous. The 5-year actuarial local relapse free survival, metastase free survival and overall survival are respectively 87.3%, 89.5% and 92.5%, whatever histological subtypes. These results are comparable to those obtained in 1393 cases of infiltrating ductal carcinoma similarly treated during the same period in our institute, except for local relapse (87.3% vs 91%, p = 0.008). Conclusion: Conservative treatment for invasive lobular carcinoma of the breast (T<35 mm) is appropriate in the absence of clinical or mammographic multifocality

    The transition of ductal carcinoma in situ (DCIS) to invasive carcinoma is a key event in breast tumor progression that is poorly understood. Comparative molecular analysis of tumor epithelial cells from in situ and invasive tumors has failed to identify consistent tumor stage-specific differences. However, the myoepithelial cell layer, present only in DCIS, is a key distinguishing and diagnostic feature. To determine the contribution of non-epithelial cells to tumor progression, we analyzed the role of myoepithelial cells and fibroblasts in the progression of in situ carcinomas using a xenograft model of human DCIS. Progression to invasion was promoted by fibroblasts, but inhibited by normal myoepithelial cells. The invasive tumor cells from these progressed lesions formed DCIS rather than invasive cancers when re-injected into naive mice. Molecular profiles of myoepithelial and epithelial cells isolated from primary normal and cancerous human breast tissue samples corroborated findings obtained in the xenograft model. These results provide the proof of principle that breast tumor progression could occur in the absence of additional genetic alterations and that tumor growth and progression could be controlled by replacement of normal myoepithelial inhibitory signals.

    2017-04-01

    We report a case of a 46-year-old female who presented with a persistent lesion on the inferior right breast. The lesion was located within the scar from a breast augmentation procedure 12 years ago. The lesion had been treated as several conditions with no improvement. Biopsy revealed a superficial and nodular basal cell carcinoma, and the lesion was successfully removed with Mohs micrographic surgery. Basal cell carcinoma arising in a surgical scar is exceedingly rare with only 13 reported cases to date. This is the first reported case of basal cell carcinoma arising in a breast augmentation scar. We emphasize the importance of biopsy for suspicious lesions or those refractory to treatment, particularly those lesions that form within a scar.

    Breast cancer is the second most common cancer worldwide and the first among women. Invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) are the two major histological subtypes, and the clinical and molecular differences between them justify the search for new markers to distinguish them. As proteomic analysis allows for a powerful and analytical approach to identify potential biomarkers, we performed a comparative analysis of IDC and ILC samples by using two-dimensional electrophoresis and mass spectrometry. Twenty-three spots were identified corresponding to 10 proteins differentially expressed between the two subtypes. ACTB, ACTG, TPM3, TBA1A, TBA1B, VIME, TPIS, PDIA3, PDIA6, and VTDB were upregulated in ductal carcinoma compared to in lobular carcinoma samples. Overall, these 10 proteins have a key role in oncogenesis. Their specific functions and relevance in cancer initiation and progression are further discussed in this study. The identified peptides represent promising biomarkers for the differentiation of ductal and lobular breast cancer subtypes, and for future interventions based on tailored therapy.

  5. Concomitant Small Cell Neuroendocrine Carcinoma of Gallbladder and Breast Cancer

    Full Text Available The neuroendocrine carcinoma is defined as a high-grade malignant neuroendocrine neoplasm arising from enterochromaffin cells, usually disposed in the mucosa of gastric and respiratory tracts. The localization in the gallbladder is rare. Knowledge of these gallbladder tumors is limited and based on isolated case reports. We describe a case of an incidental finding of small cell neuroendocrine carcinoma of the gallbladder, observed after cholecystectomy for cholelithiasis, in a 55-year-old female, who already underwent quadrantectomy and sentinel lymph-node biopsy for breast cancer. The patient underwent radiotherapy for breast cancer and six cycles of chemotherapy with cisplatin and etoposide. Eighteen months after surgery, the patient was free from disease. Small cell neuroendocrine carcinoma of the gallbladder has poor prognosis. Because of the rarity of the reported cases, specific prognostic factors have not been identified. The coexistence of small cell neuroendocrine carcinoma of the gallbladder with another malignancy has been reported only once. The contemporary presence of the two neoplasms could reflect that bioactive agents secreted by carcinoid can promote phenotypic changes in susceptible cells and induce neoplastic transformation.

    Full Text Available Abstract Background Primary Non-Hodgkin's Lymphoma (PHNL of the breast is a rare entity, while secondary involvement of the breast with diffuse disease of Non-Hodgkin's lymphoma (NHL is more common. However, PNHL is the most frequent haematopoietic tumour of the breast. Diagnostic criteria for PNHL of the breast are presence of technically adequate pathologic specimens, close association of mammary tissue and lymphomatous infiltrate, no prior diagnosis of an extarammamary lymphoma, and no evidence of concurrent widespread disease, except for ipsilateral axillary lymph nodes if concomitant with the primary lesion. Case presentation A 57-year-old woman was recalled because her screening mammograms revealed three separate lesions in her right breast and one in the left. Histology of the lesions confirmed lymphoma in one breast with ductal carcinoma in the other. Conclusion Most of reported cases in literature have been involving the right breast, and almost all the patients were females. NHLs of the breast typically present as unilateral mass; the frequency of bilateral disease at first presentation ranges from 5–25%. Our objective is to report a case of primary lymphoma of the breast involving both axillae with concomitant bilateral primary breast cancer which has not been reported yet to our best of knowledge in literature.

    We have used a modified differential display PCR protocol for isolating 3' restriction fragments of cDNAs specifically expressed or overexpressed in metastatic prostate carcinoma cell line DU145. Several cDNA fragments were identified that matched to milk fat globule protein, UFO/Axl, a receptor tyrosine kinase, human homologue of a Xenopus maternal transcript, laminin and laminin receptor, human carcinoma-associated antigen, and some expressed sequence tags. The transcript for milk fat globule protein, a marker protein shown to be overexpressed in breast tumors, was elevated in DU145 cells. The expression of UFO/Axl, a receptor tyrosine kinase, was considerably higher in DU145 cells as compared to normal prostate cells and prostatic carcinoma cell line PC-3. The overexpression of UFO oncogene in DU145 cells is discussed in the context of prostate cancer metastasis.

    Breast cancer is rare in children and adolescents. In particular, there are very few cases of invasive ductal carcinoma in childhood. We report a case of invasive ductal carcinoma of the breast in a 14-year-old girl presenting as a palpable mass. While the tumor demonstrated a relatively benign appearance on ultrasound, magnetic resonance imaging revealed typical malignant features. Several polymorphisms of single nucleotide variation were observed on gene analysis. The patient underwent breast conserving surgery and received subsequent concurrent chemo-radiation therapy. An awareness that ductal carcinoma of the breast rarely occurs in children is important to detect early stage breast cancer. (orig.)

    We report a case of isolated gastrointestinal metastasis from breast lobular carcinoma, which mimicked primary anal cancer. In July 2000, an 88-year-old woman presented with infiltrating lobular cancer (pT1/G2/N2). The patient received postoperative radiotherapy and hormonal therapy. Four years later, she presented with an anal polypoid lesion. The mass was removed for biopsy. Immunohistochemical staining suggested a breast origin. Radiotherapy was chosen for this patient, which resulted in complete regression of the lesion. The patient died 3 years after the first manifestation of gastrointestinal metastasis. According to the current literature, we consider the immunohistochemistry features that are essential to support the suspicion of gastrointestinal breast metastasis, and since we consider the gastrointestinal involvement as a sign of systemic disease, the therapy should be less aggressive and systemic.

    2016-12-01

    Full Text Available Breast Ultrasound (US is an important tool for both screening and diagnostic examinations. Although breast US has benefitted from significant recent technical improvements, its use for the retroareolar region is known to be more challenging than for other locations. The retroareolar location was defined by Giess et al. in 1998 as the region where any lesion is situated at less than two cm from the nipple and/or involves the nipple-areolar complex on mammogram. Understanding of the complex anatomy and physiology of the nipple-areolar region is important to avoid misinterpretation and misdiagnosis. The ability for the breast imager to manage difficulties related to the retroareolar area is paramount by adjusting settings (compounding, frequency, Doppler and utilizing specific manoeuvers. Cases illustrating difficulties encountered in diagnosis of retroareolar carcinomas are presented.

    Full Text Available Background: Glycogen-rich clear cell breast carcinoma is a rare histological breast cancer subtype. Its prognosis may vary depending on specific clinical and pathological characteristics such as low grade, strong positivity of estrogen receptor (ER expression and early diagnosis. Case Presentation: We present the case of a 53-year-old woman with a bleeding 10-cm-diameter mass in the left breast. The histological examination showed a poorly differentiated tumor with malignant cells characterized by abundant clear cytoplasm. The diagnosis of clear cell carcinoma was based on the histological characteristics of the tumor, and a nonmammary origin was initially ruled out. The tumor was triple negative [i.e. ER, progesterone receptor (PR and HER2 negative]. Four months after the initial locoregional treatment, the patient developed lung and distant lymph node metastases. Conclusions: Glycogen-rich clear cell carcinoma of the breast is a rare tumor. Early diagnosis, absence of lymph node metastases and ER/PR positivity are associated with a better prognosis, as in other common breast cancer subtypes.

    The results are presented of 186 breast cancer patients treated initially for locoregional disease by radiotherapy alone, combining cobalt therapy with external electron beam or interstitial iridium implants. According to the TNM classification, the patients were distributed as follows: 3 T 1 N 0 , 2 T 1 N 1 , 33 T 2 N 0 , 36 T 2 N 1 , 16 T 3 N 0 , 26 T 3 N 1 , 6 T 3 N 2 , 14 T 4 N 0 , 29 T 4 N 1 , 9 T 4 N 2 and 12 T 4 N 3 . The 5- and 10-year survival rates (52.7 and 36.5 per cent respectively, for all patients) were directly correlated with the size and location of the breast tumor, and the extent of lymph node involvement. Locoregional recurrence was observed in 39.8 per cent of the cases, metastases alone in 26.8 per cent, and a combination of local recurrence and distant metastasis in 14.5 per cent of the cases. The local recurrences and metastases were directly correlated with the extent of locoregional involvement. Late complications and sequelae were mostly minor and occurred in less than 25 per cent of the cases; severe sequelae in no more than 2 per cent. They depended on the initial tumor volume and the tumor dose. The results, along with those in the literature, indicate that radiotherapy administered alone is a valid therapeutic option in breast cancer. (author). 23 refs.; 5 tabs

    Breast metastases are a relatively rare condition and account for approximately 0.5-2% of all breast tumors. Recognition of metastatic tumors in the breast is important because it would prevent unnecessary mutilating surgery and would lead to appropriate treatment of the primary tumor. Breast metastases from medullary thyroid cancer (MTC) are very rare with only 21 reported cases in the literature. Some MTCs mimic primary invasive lobular carcinoma of the breast histopathologically and radiologically, making the distinction between the two diagnostically challenging. We present the case of a 45-year-old female presenting with a lump breast, which was later found out to be metastasis from medullary carcinoma thyroid.

    Even with adequate history, the distinction of cutaneous metastatic breast carcinoma from primary sweat gland carcinoma can be difficult. Although previous studies have attempted to separate these tumors with various immunohistochemical panels, those series have been limited by small numbers of patients as well as the inclusion of benign sweat gland tumors. In this analysis, stains for p63, CK5/6, and D2-40 were included, as well as GATA3 and mammaglobin, in an evaluation of 21 primary sweat gland carcinomas and 33 examples of cutaneous metastatic breast carcinoma. Immunoreactivity for p63, CK5/6, D2-40, GATA3, and mammaglobin was respectively observed in 81%, 71%, 52%, 71%, and 5% of sweat gland carcinomas compared with 6%, 6%, 6%, 91%, and 45% of metastatic breast carcinomas. These differences were statistically significant for p63, CK5/6, and D2-40. For the diagnosis of metastatic breast carcinoma, GATA3 was the most sensitive marker (91%), but its sensitivity was substantially lower. Mammaglobin was 95% specific for breast carcinoma but again suffered from limited sensitivity (45%) in this context. These data suggest that p63 and CK5/6 are specific determinants for sweat gland carcinoma in the stated setting. In the absence of those analytes, metastatic breast carcinoma cannot always be identified to the exclusion of a primary tumor. This diagnostic scenario continues to require the procurement of a detailed clinical history regarding the number and duration of skin lesions in any given case.

    Full Text Available Matrix-producing breast cancer (MPC is a subtype of metaplastic carcinoma of the breast. It is a very rare tumor, which constitutes less than 1% of all malignant mammary tumors. The origin of this tumor is still unclear: there are molecular studies that suggest an origin from myoepithelial cells, whereas other studies underline the neoplastic transformation of a multipotent stem cell. Even the differential diagnosis of MPC and other breast neoplasms (phyllodes tumors and real sarcomas of the breast is not always easy. In the literature, a certain chemoresistance has been demonstrated, and a standard treatment of this tumor does not exist at this time. We report the case of a 44-year-old, premenopausal, female patient with a 6-cm breast lump. Neither imaging nor fine needle aspiration biopsy was crucial in achieving a diagnosis. The patient underwent a simple mastectomy. In consideration of the negative lymph node status, the patient was not subjected to radiotherapy or adjuvant chemotherapy. Moreover, since the receptor status was negative, hormone therapy was not necessary. The patient has been disease free for 4 years now.

    Breast cancer is a common cancer among women. The transverse rectus abdominis myocutaneous (TRAM) flap is a popular option because not only does it provide a breast with satisfactory bulk composed of autogenous tissue but it also provides an abdominal dermolipectomy to the patient. Fat necrosis remains a common problem following TRAM flap reconstruction, occurring in 10% to 36% of patients undergoing the procedure. A 44-year-old woman underwent a modified radical mastectomy followed by pedicled TRAM flap reconstruction after 5 months. Follow-up mammography 27 months after TRAM flap reconstruction showed a cluster of microcalcifications in the deep retroareolar area and recurrent breast carcinoma was highly suspected. Physical examination did not detect any abnormality of the reconstructed breast. Stereotactic hook localization was performed and an excisional biopsy was successfully done. The histological features of the resected specimens corresponded to fat necrosis change. Only with the awareness of the existence of such entity and careful follow-up can the occurrence of fat necrosis in TRAM flap reconstructed breasts be accurately detected and appropriately treated.

    The prospective study was carried out on 183 patients with histologically proven breast cancer received at Khartoum Teaching Hospital and Soba Hospital between January 1996 to May 1998. Most of the patients were from Khartoum State followed by patients coming from Western, Central and Northern states with incidence of 17%, 16% and 15% respectively. Gaalein, shaigia, mahas and rizigat were the commonest affected tribes in western Sudan. Few patients were from southern and northern Sudan. Genetic and environmental factors may be contributory factors. The incidence of male breast cancer was 3%, which is higher than that reported in the western world. In this study young age group, early menarche, late first pregnancy and nulliparity were the main risk factors. The multiparity, lactation and lack of positive family history did not protect our patients from developing breast cancer. Most of the patients presented with locally advanced for the disease. This is due to the aggressive nature of breast cancer among black population. Lung, bone and liver were the most frequent sites for metastases. Chest x-ray and skeletal survey were diagnostic of metastases. Ductal carcinoma was the commonest type of breast cancer in this study. Laboratory investigations in the form of full blood count, liver function test , blood urea and serum electrolytes have no prognostic value in our patients.(Author)

    Fibroadenoma is a commonly found benign tumor of the breast; however carcinoma in a fibroadenoma is rarely encountered. In this paper we described a case of fibroadenoma difficult to differentiate from carcinoma. A 17-year-old woman visited our hospital complaining of a left breast lump. Ultrasonography showed a well-defined and hypoechoic ovoid mass. Excisional biopsy was done and diagnosed as fibroadenoma; however it was difficult to differentiate histologically from carcinoma.

    Full Text Available Pure mucinous carcinoma is a rare special type of breast carcinoma with a 2% incidence and it is usualy asociated with a good prognosis. It must distingished from the mixed subtype of mucinos breast carcinoma, which has an invasive non-mucinous component in more than 10% of the tumor and change the favourable outcome of the first subtype. In this report we present a case of a premenopausal woman with a lump in right breast wich histopathologically proved to be a pure mucinous carcinoma associated with high grade ductal carcinoma in situ. Immunohistochemical and ancillary studies demonstrate a great heterogeneity of the neoplastic cells, with different molecular profile for each component of the tumor. The presence of ductal carcinoma in situ with a different imunophenotype from pure mucinous carcinoma rise the ipothesis of a different tumor cell biology which may change clincal evolution.

    2006-01-01

    We recently undertook expression profiling of all 19 human ADAMTS metalloproteinases (a disintegrin and metalloproteinase with thrombospondin motifs) in malignant and non-neoplastic breast tissue and showed that 11 of the ADAMTS genes are dysregulated in breast carcinoma. We identified a subgroup...... of ADAMTSs, based on functional and amino acid sequence similarity (ADAMTS1, 4, 5, 8 and 15), to be the focus of further study in breast carcinoma. Further RNA expression analysis by real-time PCR on a different cohort of 229 patients with breast cancer has identified ADAMTS8 as a predictor of poor overall...... breast carcinoma, fitted the expectation that relatively high expression levels of ADAMTS8 together with low expression levels of ADAMTS15 seen in human breast carcinoma are associated with a poor clinical outcome. In summary, ADAMTS8 and ADAMTS15 have emerged as novel predictors of survival in patients...

    Full Text Available We present a rare distinctive variant of invasive carcinoma of breast characterized by adnexal differentiation of tumor of trichoblastic type. The neoplasm was identified in a mastectomy specimen from an 83-year-old Chinese woman. Morphologically, the trichoblastic differentiation was characterized by the formation of solid sheets and nests of basaloid cells. The tumor cells were positive for cytokeratin 5/6, BER-EP4, bcl-2, and beta-catenin. Stromal cells were positive for CD10. The tumor cells exhibited a and ldquo;triple negative and rdquo; profile; the nuclei did not react with antibodies to estrogen and progesterone receptors but failed to show overexpression of the HER2/neu protein. The MIB-1 labeling index averaged 20%. It is hoped that this case increases awareness for this unique morphological variant of invasive ductal carcinoma.

    Objective: To evaluate the utility and role of fine needle aspiration cytology (FNAC) in essential surgical management of carcinoma breast. Patients and Methods: The study included one hundred cases of carcinoma of breast-97 females and 3 males, confirmed on histopathological examination and surgically treated at PNS Shifa, CMH Pano Aqil and PNS Rahat. FNA cytology was the primary tool of investigation in all. The benefit of the procedure was evaluated considering the ease of the procedure, cost, safety, reliability as screening procedure and its effect on sparing the patients from excision or incision biopsy and thus additional anesthesia. Results: Sensitivity of the procedure was 78%, specificity 100%, predictive value 100% and overall diagnostic accuracy 72%. Out of 78 cases, diagnosed as positive for malignancy on FNAC and later confirmed by histopathological examination, 58 underwent frozen section examination followed by definitive surgery (modified radical mastectomy). Remaining 20 cases underwent additional core biopsy. Out of these, 12 cases underwent definitive surgery without frozen section and 8 patients underwent frozen section examination followed by definitive surgery. A single case required general anesthesia (GA) while the patients undergoing core biopsy required a local anesthesia (LA) as well. Cases remaining undiagnosed by FNA-cytology (22 cases) required either an excision biopsy (17 cases) or incision biopsy (5 cases) under GA followed by definitive surgery, thus requiring general anesthesia twice during the management. Conclusion: FNA-cytology can positively affect the surgical management of carcinoma breast. It can be utilized to select the patients for frozen selection examination and can thus spare the patients from additional procedure of excision or incision biopsy under separate anesthesia. It may be adopted as a routine procedure in surgical outpatient. (author)

  11. Gene therapy for carcinoma of the breast: Genetic ablation strategies

    2000-01-01

    The gene therapy strategy of mutation compensation is designed to rectify the molecular lesions that are etiologic for neoplastic transformation. For dominant oncogenes, such approaches involve the functional knockout of the dysregulated cellular control pathways provoked by the overexpressed oncoprotein. On this basis, molecular interventions may be targeted to the transcriptional level of expression, via antisense or ribozymes, or post-transcriptionally, via intracellular single chain antibodies (intrabodies). For carcinoma of the breast, these approaches have been applied in the context of the disease linked oncogenes erbB-2 and cyclin D 1 , as well as the estrogen receptor. Neoplastic revision accomplished in modal systems has rationalized human trials on this basis

    Full Text Available Neuroendocrine carcinoma of the breast (NECB is a subtype of breast cancer. The diagnostic criteria of primary NECB were established in 2003 and updated in 2012. It is a rare entity, and few studies have reported the histogenesis, immunohistochemistry for a pathological diagnosis, clinical behavior, therapeutic strategies, and the prognostic factors. Because of the rarity of this disease, consistent diagnostic criteria will remind physicians of this disease when making a differential diagnosis to enable a timely diagnosis and prompt treatment. Herein, we report a case of primary NECB who presented with a history of right hip pain arising from an osteolytic lesion in the right acetabulum and ischium. The course of investigation started with metastasis in the right hip and concluded with a diagnosis of NECB. In addition to the case report, we also conducted a literature review.

    Adenomyoepithelioma of the breast is a rare tumor. A myoepithelial carcinoma arising within an adenomyoepithelioma is even more unusual. There are a limited number of reports discussing myoepithelial carcinoma; most of them describe pathological findings, but not imaging findings. We present a case of a 55-year-old woman who had a screen-detected myoepithelial carcinoma arising within an adenomyoepithelioma in her right breast. Upon the completion of a mammography and sonography an oval shaped mass with an indistinct margin in the upper portion of the right breast had been seen. It as appeared to be a spiculated, irregular-shaped, peripheral-enhancing mass on an MRI. On sonography-guided biopsy, an epithelial-myothelial tumor was confirmed, and the possibility of myoepithelial carcinoma was suggested. Breast-conserving surgery with a sentinel lymph node dissection was performed, and a pathological examination revealed a myoepithelial carcinoma arising within an adenomyoepithelioma.

    1996-01-01

    Purpose: To assess outcome of patients with bilateral breast carcinoma treated with bilateral breast conserving surgery with radiation therapy (CS+RT) and to compare their outcome to (1) patients with unilateral disease treated with CS+RT and (2) patients of comparable stage treated with bilateral mastectomy. Methods and Materials: The charts of all patients with the diagnosis of breast cancer treated with CS+RT at our facilities prior to 1993 were reviewed to identify patients with bilateral disease. A total of 50 patients identified as having bilateral breast cancer conservatively treated(BCT) served as the index population. Out of the 50 patients, 23 presented with synchronous bilateral breast cancer and 27 presented with metachronous bilateral breast cancer. A group of 984 patients with unilateral breast cancer (UCT) treated with CS+RT during the same time interval served as the first control group. A second control group was comprised of 42 patients with early stage bilateral breast cancer presenting during the same time interval treated with bilateral mastectomy (BMAST). Patients who had locally advanced disease in either breast or those patients treated exclusively for lobular carcinoma in situ in either breast were excluded from the analysis. Of the 42 BMAST patients, 33 presented with synchronous disease and nine presented with metachronous disease. Local-regional relapse rates were calculated from the date of treatment of each breast. Overall survival and distant relapse rates were calculated from the date of treatment of the second breast cancer diagnosed. Survival curves were calculated via the life table method and statistical comparisons between curves were performed using the log rank statistic. Chi square analysis was used to detect differences between categorical variables. Results: As of December 1995, the median follow-up of the bilateral conservatively treated patient population was 9.4 years. No statistically significant differences were noted

    Bone marrow scintigraphy was performed in 259 patients including 124 females with breast carcinoma using the technique of 99m Tc-labelled colloid retention by phagocytizing cells, thus visualizing the reticuloendothelial component of the bone marrow. The objective was to early diagnose hematogenic metastases. In five patients, simultaneous skeleton scintiscanning was not performed. The technique was shown to play a role in early diagnosis of bone metastases and of bone lesions in less usual loci and especially in the differential diagnosis of nonmalignant bone disease, such as arthrosis. Its constraints include an intensive cumulation of the radiopharmaceutical in the liver and the splenic reticuloendothelial systems, which precludes the assessment of the bone marrow in the adjacent areas; further a difficult interpretation of the results, high cost and long time of examination. It has no role in patients with disseminated forms of the disease with multiple bone metastases already shown by scintigraphy. Bone marrow scintigraphy alone is not a reliable method for early diagnosis of breast carcinoma (L.O.)

  18. A model of tumor architecture and spatial interactions with tumor microenvironment in breast carcinoma

    Breast carcinomas are cancers that arise from the epithelial cells of the breast, which are the cells that line the lobules and the lactiferous ducts. Breast carcinoma is the most common type of breast cancer and can be divided into different subtypes based on architectural features and growth patterns, recognized during a histopathological examination. Tumor microenvironment (TME) is the cellular environment in which tumor cells develop. Being composed of various cell types having different biological roles, TME is recognized as playing an important role in the progression of the disease. The architectural heterogeneity in breast carcinomas and the spatial interactions with TME are, to date, not well understood. Developing a spatial model of tumor architecture and spatial interactions with TME can advance our understanding of tumor heterogeneity. Furthermore, generating histological synthetic datasets can contribute to validating, and comparing analytical methods that are used in digital pathology. In this work, we propose a modeling method that applies to different breast carcinoma subtypes and TME spatial distributions based on mathematical morphology. The model is based on a few morphological parameters that give access to a large spectrum of breast tumor architectures and are able to differentiate in-situ ductal carcinomas (DCIS) and histological subtypes of invasive carcinomas such as ductal (IDC) and lobular carcinoma (ILC). In addition, a part of the parameters of the model controls the spatial distribution of TME relative to the tumor. The validation of the model has been performed by comparing morphological features between real and simulated images.

    Lobular carcinoma in situ (LCIS) clinically constitutes a risk factor for the subsequent development of either invasive lobular carcinoma (ILC) or invasive ductal carcinoma (IDC). In order to approach the possibility of this common precursor of both ILC and IDC, we investigated combined lobular and ductal carcinomas. Thirty-two cases of lobular carcinoma were picked up out of 773 cases of operated breast carcinomas. The histopathological detailed re-examination using immunostain of E-cadherin and β-catenin revealed a rather high frequency of combined lobular carcinomas than previous reports. Clinicopathologically, combined lobular carcinomas were younger and smaller than pure lobular carcinomas, and the cytological atypia was relatively low. These results suggested that combined lobular carcinomas could be detected in the earlier stage of breast cancer. Furthermore, the lobular and ductal components of combined carcinomas coexisted in the neighborhood and were distributed contiguously. The immunohistochemical phenotypes of both components were accorded in most combined cases. A genetic analysis using methylation-specific PCR on the HUMARA gene demonstrated that the same allele was inactivated in both lobular and ductal components in all detectable cases of combined carcinoma. Therefore, it is reasonable to assume that both lobular and ductal components of combined carcinomas are clonal and derived from the LCIS as the common precursor lesion, which may contradict the conventional concept that the lobular and ductal carcinomas arise from distinct differentiation pathways.

    Primary neuroendocrine carcinoma of the breast is a very rare malignant tumor. There are not many cases reported in the English literature since it was first documented in 1983. Reports on the imaging features, in particular the ultrasonographic features of this rare tumor are scarce. Herein, we report a case of aggressive primary infiltrating neuroendocrine carcinoma of the breast, masquerading as an inflammatory breast condition in a 22-year-old young lady, perhaps the youngest case ever reported in the English literature. We discuss the imaging features and highlight the Doppler ultrasonographic findings of this rare breast carcinoma. This is the first documentation on Doppler ultrasonographic findings of primary neuroendocrine carcinoma of the breast in the literature

    Full Text Available INTRODUCTION: Epstein-Barr virus (EBV-associated tumors show different expression patterns of latency genes. Since in breast carcinoma this pattern is not yet fully described, our aim was to characterize EBV latency pattern in our EBV positive breast carcinoma series. METHODS: The study was conducted on 71 biopsies of breast carcinoma and in 48 non-neoplastic breast controls. EBNA1, LMP2A and LMP1 expression was assessed by immunohistochemistry with monoclonal antibodies, while viral genomic DNA and EBERs RNA transcripts expression was performed by in situ hybridization. EBV presence was confirmed by PCR. RESULTS: EBV genomic DNA and EBNA1 expression were detected in 31% (22/71 of patients specifically restricted to tumor epithelial cells in breast carcinoma while all breast control samples were negative for both viral DNA and EBNA1 protein. LMP2A was detected in 73% of EBNA1 positive cases, none of which expressed either LMP1 protein or EBERs transcripts. CONCLUSIONS: These findings suggest that EBV expression pattern in the studied biopsies could be different from those previously observed in breast carcinoma cell lines and lead us to suggest a new, EBNA1, LMP2A positive and LMP1 and EBERs negative latency profile in breast carcinoma in our population.

    Full Text Available Abstract Background Prostate carcinoma is among the most common solid tumors to secondarily involve the male breast. Prostate specific antigen (PSA and prostate-specific acid phosphatase (PSAP are expressed in benign and malignant prostatic tissue, and immunohistochemical staining for these markers is often used to confirm the prostatic origin of metastatic carcinoma. PSA expression has been reported in male and female breast carcinoma and in gynecomastia, raising concerns about the utility of PSA for differentiating prostate carcinoma metastasis to the male breast from primary breast carcinoma. This study examined the frequency of PSA, PSAP, and hormone receptor expression in male breast carcinoma (MBC, female breast carcinoma (FBC, and gynecomastia. Methods Immunohistochemical staining for PSA, PSAP, AR, ER, and PR was performed on tissue microarrays representing six cases of gynecomastia, thirty MBC, and fifty-six FBC. Results PSA was positive in two of fifty-six FBC (3.7%, focally positive in one of thirty MBC (3.3%, and negative in the five examined cases of gynecomastia. PSAP expression was absent in MBC, FBC, and gynecomastia. Hormone receptor expression was similar in males and females (AR 74.1% in MBC vs. 67.9% in FBC, p = 0.62; ER 85.2% vs. 68.5%, p = 0.18; and PR 51.9% vs. 48.2%, p = 0.82. Conclusions PSA and PSAP are useful markers to distinguish primary breast carcinoma from prostate carcinoma metastatic to the male breast. Although PSA expression appeared to correlate with hormone receptor expression, the incidence of PSA expression in our population was too low to draw significant conclusions about an association between PSA expression and hormone receptor status in breast lesions.

    Metastastic carcinoma to extraocular muscles is extremely rare, but even more so is the case of a bilateral one. A 50-year-old woman with a history of mastectomy for a T4N1M0 right breast carcinoma was referred to us with diplopia due to bilateral extraocular muscle metastases, 5 years post mastectomy. Multiple metastases to the whole body were also present. A combination of high-dose irradiation, hormonotherapy and chemotherapy were performed. Despite the multidisciplinary treatment approach, the diplopia persisted. A literature review revealed only 4 cases of bilateral metastases to extraocular muscles. The present case is the second attributed to lobular carcinoma and the only one treated with a high dose of radiotherapy combined with systemic therapy. In a cancer patient, any orbital change must be examined for the possibility of an extraocular metastasis. Conclusions affecting the optimal treatment policy of extraocular muscle metastases are difficult to determine, due to the small number of reported cases. (c) 2008 S. Karger AG, Basel

    Purpose: Chemotherapy and accelerated superfractionated radiotherapy were prospectively applied for inflammatory breast carcinoma with the intent of breast conservation. The efficacy, failure patterns, and patient tolerance utilizing this approach were analyzed. Methods and Materials: Between 1983 and 1996, 52 patients with inflammatory breast carcinoma presented to the Medical College of Virginia Hospitals of VCU and the New England Medical Center. Thirty-eight of these patients were jointly evaluated in multidisciplinary breast clinics and managed according to a defined prospectively applied treatment policy. Patients received induction chemotherapy, accelerated superfractionated radiotherapy, selected use of mastectomy, and concluded with additional chemotherapy. The majority were treated with 1.5 Gy twice daily to field arrangements covering the entire breast and regional lymphatics. An additional 18-21 Gy was then delivered to the breast and clinically involved nodal regions. Total dose to clinically involved areas was 63-66 Gy. Following chemoradiotherapy, patients were evaluated with physical examination, mammogram, and fine needle aspiration x 3. Mastectomy was reserved for those patients with evidence of persistent or progressive disease in the involved breast. All patients received additional chemotherapy. Results: Median age was 51 years. Median follow-up was 23.9 months (6-86) months. The breast preservation rate at the time of last follow-up was 74%. The treated breast or chest wall as the first site of failure occurred in only 13%, and the ultimate local control rate with the selected use of mastectomy was 74%. Ten patients underwent mastectomy, 2 of which had pathologically negative specimens despite a clinically palpable residual mass. Response to chemotherapy was predictive of treatment outcome. Of the 15 patients achieving a complete response, 87% remain locoregionally controlled without the use of mastectomy. Five-year overall survival for

    Full Text Available Neurofibromatosis I (NF I, an autosomal dominant disorder is associated with increased risk of benign and malignant peripheral nerve sheath tumors and central nervous system tumors. There are only few case reports of breast carcinoma in known patients of NF I. We report a case of basal like carcinoma of the breast in a 69-year-old lady who had NF I. Considering the rare association of carcinomas with NF I and finding that both the NF I gene and a breast cancer pre-disposition gene, BRCA 1 are located in close proximity on chromosome 17q makes the association of these two conditions intriguing.

    Full Text Available Neurofibromatosis type 1 (NF1 has been associated with an increased risk for development of malignancy, especially malignant peripheral nerve sheath tumors. In addition, recently, literature has demonstrated an increased risk of breast cancer in women with NF1. The present paper shows a 53-year-old woman with NF1 who presented with metaplastic breast carcinoma and developed multiple metastases, including mandible. Furthermore, we reviewed the English literature, found 63 cases showing the association between NF1 and breast cancer, and added one more case. The present study demonstrated an important association between NF1 and breast cancer. Until the present time, there has been only one case of metaplastic breast carcinoma associated with NF1. Curiously, in our case the oral metastasis corresponded to sarcomatous component of metaplastic breast carcinoma.

    Full Text Available Background. Breast carcinoma is the most common malignancy in women worldwide. It is most commonly associated with metastases to the liver, lung, bone, and the brain. Invasive lobular carcinoma is a less common pathology with slightly higher metastases to the upper gastrointestinal tract. Invasive lobular carcinoma metastasis to the gallbladder is extremely rare. Method. In this paper we are presenting a case of a 67-year-old female with metastases of invasive lobular breast cancer to the gallbladder six years after her therapy. Conclusion. This case clearly signifies the nature of the micrometastatic foci of the invasive lobular carcinoma even many years after a successful treatment.

    The morphology of breast tumors is complicated and diagnosis can be difficult. We present here a novel diagnostic model which we validate on both array-based and RNA sequencing platforms which reliably distinguishes this tumor type across multiple cohorts. We also examine how this molecular classification predicts sensitivity to common chemotherapeutics in cell-line based assays. A total of 1845 invasive breast cancer cases in six cohorts were collected, split into discovery and validation cohorts, and a classifier was created and compared to pathological diagnosis, grade and survival. In the validation cohorts the concordance of predicted diagnosis with a pathological diagnosis was 92%, and 97% when inconclusively classified cases were excluded. Tumor-derived cell lines were classified with the model as having predominantly ductal or lobular-like molecular physiologies, and sensitivity of these lines to relevant compounds was analyzed. A diagnostic tool can be created that reliably distinguishes lobular from ductal carcinoma and allows the classification of cell lines on the basis of molecular profiles associated with these tumor types. This tool may assist in improved diagnosis and aid in explorations of the response of lobular type breast tumor models to different compounds. PMID:28303886

  12. Colorectal carcinomas in MUTYH-associated polyposis display histopathological similarities to microsatellite unstable carcinomas

    MUTYH-associated polyposis (MAP) is a recessively inherited disorder which predisposes biallelic carriers for a high risk of polyposis and colorectal carcinoma (CRC). Since about one third of the biallelic MAP patients in population based CRC series has no adenomas, this study aimed to identify specific clinicopathological characteristics of MAP CRCs and compare these with reported data on sporadic and Lynch CRCs. From 44 MAP patients who developed ≥ 1 CRCs, 42 of 58 tumours were analyzed histologically and 35 immunohistochemically for p53 and beta-catenin. Cell densities of CD3, CD8, CD57, and granzyme B positive lymphocytes were determined. KRAS2, the mutation cluster region (MCR) of APC, p53, and SMAD4 were analyzed for somatic mutations. MAP CRCs frequently localized to the proximal colon (69%, 40/58), were mucinous in 21% (9/42), and had a conspicuous Crohn's like infiltrate reaction in 33% (13/40); all of these parameters occurred at a higher rate than reported for sporadic CRCs. Tumour infiltrating lymphocytes (TILs) were also highly prevalent in MAP CRCs. Somatic APC MCR mutations occurred in 14% (5/36) while 64% (23/36) had KRAS2 mutations (22/23 c.34G>T). G>T tranversions were found in p53 and SMAD4, although the relative frequency compared to other mutations was low. MAP CRCs show some similarities to micro-satellite unstable cancers, with a preferential proximal location, a high rate of mucinous histotype and increased presence of TILs. These features should direct the practicing pathologist towards a MAP aetiology of CRC as an alternative for a mismatch repair deficient cause. High frequent G>T transversions in APC and KRAS2 (mutated in early tumour development) but not in P53 and SMAD4 (implicated in tumour progression) might indicate a predominant MUTYH effect in early carcinogenesis

  13. Pleomorphic Lobular Carcinoma of the Breast: Clinicopathological Analysis of a Distinctive and Rare Variant of Lobular Carcinoma

    2016-12-01

    Full Text Available Pleomorphic lobular carcinoma (PLC of the breast is an uncommon variant of invasive lobular carcinoma (ILC, accounting for 0.67% of all breast carcinomas and <5% of lobular carcinoma. This lesion is usually misdiagnosed as infiltrating ductal carcinoma. It has been identified as a distinct entity from classic ILC and is reported to be associated with a more aggressive clinical behavior than classic lobular carcinoma. In this report, we aim to describe radiological and pathological characteristics of PLC and to review the therapeutic management. We present a new case of PLC occurring in a 74-year-old woman, consulting for a retro-areolar mass in the right breast, measuring 3 cm in great diameter. She underwent a mastectomy. The tumor was described as PLC. Radiologically, the PLC is most commonly similar to invasive ductal carcinoma. It is described as a speculated mass on mammography or ultrasonography. However, unlike the classic variant, the tumor cells of the pleomorphic variant of ILC are larger and have abundant cytoplasm with large hyperchromatic nuclei that show prominent nucleoli. Positivity for hormone receptors and amplification of human epidermal growth factor-2/neu in PLC suggest that endocrine-related targeted therapy and trastuzumab may be valuable treatment regimens for these patients.

    Full Text Available Carcinoma of the cervix is the most common malignancy among women in India. Although metastatic disease is common, metastasis to breast is rare. A limited number of case reports are published in the world literature. Most of the previous reports of metastatic cervical carcinoma to breast are either autopsy series or widely disseminated disease where no treatment options were available. A rare case of cervical carcinoma presenting as metastasis in breast is reported here where palliative mastectomy improved the general condition of the patient. A female patient aged 58 years was diagnosed and treated for cervical carcinoma, FIGO stage 2B. Four months after the treatment which included both external beam and intracavitory radiotherapy, the patient presented with breast and lung metastasis. Palliative mastectomy was done which improved the general condition of the patient. Metastatic carcinoma of the cervix can present as a case of breast carcinoma. In an appropriate setting, this possibility should be kept in mind. Palliative mastectomy should be offered for patients of cervical carcinoma with metastasis to breast when needed.

    Invasive lobular carcinomas have an increased propensity for distant metastases, particularly to the peritoneum, ovaries, and uterus. In contrast, distant metastases of nonpalpable lobular carcinomas are extremely rare, and the causes of underlying symptoms of primary carcinomas remain unclear. We report a case of an asymptomatic invasive lobular carcinoma with a primary mammary lesion in a patient with rectal stenosis. A 69-year-old Japanese woman presented to our hospital for treatment of constipation. Although rectal stenosis was confirmed, thorough testing of her lower digestive tract did not identify its cause. Thus, an exploratory laparotomy and tissue biopsy was performed, and the presence of an invasive lobular carcinoma was confirmed. Subsequent breast examinations showed that the invasive lobular carcinoma that led to the rectal stenosis was a metastatic lesion from a primary lesion of the breast duct. As the present breast lobular carcinoma was asymptomatic and nonpalpable, we did not initially consider metastatic breast cancer as a cause of her symptoms, and the final diagnosis was delayed. Peritoneal metastasis from nonpalpable invasive lobular carcinomas is very rare. However, breast cancer metastasis should be considered when carcinomatous peritonitis is present in a patient with an unknown primary cancer.

    2016-04-01

    Full Text Available Background: Occurrence of gastric metastasis as the first symptom of breast carcinoma with a long period of latency before presentation of the primary breast carcinoma is rare. Case Report: A patient with gastric metastasis as the first symptom of lobular breast carcinoma, treated by neoadjuvant preoperative chemoradiotherapy and total gastrectomy, with complete local control. Fourteen months after presentation of the gastric metastasis a primary lobular breast carcinoma was discovered, treated by radiotherapy, chemotherapy and hormonal treatment with complete local response. Twenty-three months after diagnosis of breast cancer multiple colorectal metastases from the breast cancer occurred, which were treated by chemotherapy and hormonal treatment. Eighty-six months after diagnosis of gastric metastasis the patient died due to progression of cancer. Conclusions: Metastases to gastrointestinal or gynaecological tracts are more likely in invasive lobular carcinoma than invasive ductal cancer. The pathologist should determine whether or not they check estrogen and progesterone receptor status not simply by signet ring cell morphology but also by consideration of clinic-pathological correlation of the patient, such as the presence of a past history of breast cancer, or the colorectal localization of poorly differentiated carcinoma, which may occur less frequently than in the stomach.

    Breast cancer represents the second leading cause of cancer mortality among American women and accounts for more than 40 000 deaths annually. High-mobility group A1 (HMGA1) expression has been implicated in the pathogenesis and progression of human malignant tumours, including breast carcinomas. The aim of this study was to evaluate HMGA1 detection as an indicator for the diagnosis and prognosis of human breast carcinoma. HMGA1 expression has been analysed by immunohistochemistry in a large series of breast carcinoma resections (1338) combined on a tissue microarray mainly including the ductal carcinoma variant. The results were then correlated with clinicopathological parameters of patients. HMGA1 overexpression was found in the large majority of breast carcinoma samples and its overexpression positively correlated with HER-2/neu amplification and progesterone receptor, while a negative correlation was found with oestrogen receptor. Conversely, no HMGA1 expression was found in normal breast tissues. The data reported here indicate that HMGA1 is overexpressed in human breast carcinomas and its levels are associated with a particular endocrine status. Published by the BMJ Publishing Group Limited.

    While tuberculosis is still the leading opportunistic infection among human immunodeficiency virus-seropositive patients, extra-pulmonary tuberculosis is more common than pulmonary tuberculosis, with lymph nodes being a common site. Axillary lymph node pathology such as tuberculosis and lymphoma rarely mimics inflammatory breast carcinoma by producing lymphatic obstruction. We report a case of axillary lymph node tuberculosis in a 40-year-old immune-compromised woman, clinically presenting as inflammatory breast carcinoma. © The Author(s) 2015.

    Full Text Available Abstract Background This retrospective study aims to determine: 1 the sensitivity of preoperative mammography (Mx and ultrasound (US, and re-reviewed Mx to detect multifocal multicentric breast carcinoma (MMBC, defined by pathology on surgical specimens, and 2 to analyze the characteristics of both detected and undetected foci on Mx and US. Methods Three experienced breast radiologists re-reviewed, independently, digital mammography of 97 women with MMBC pathologically diagnosed on surgical specimens. The radiologists were informed of all neoplastic foci, and blinded to the original mammograms and US reports. With regards to Mx, they considered the breast density, number of foci, the Mx characteristics of the lesions and their BI-RADS classification. For US, they considered size of the lesions, BI-RADS classification and US pattern and lesion characteristics. According to the histological size, the lesions were classified as: index cancer, 2nd lesion, 3rd lesion, and 4th lesion. Any pathologically identified malignant foci not previously described in the original imaging reports, were defined as undetected or missed lesions. Sensitivity was calculated for Mx, US and re-reviewed Mx for detecting the presence of the index cancer as well as additional satellite lesions. Results Pathological examination revealed 13 multifocal and 84 multicentric cancers with a total of 303 malignant foci (282 invasive and 21 non invasive. Original Mx and US reports had an overall sensitivity of 45.5% and 52.9%, respectively. Mx detected 83/97 index cancers with a sensitivity of 85.6%. The number of lesions undetected by original Mx was 165/303. The Mx pattern of breasts with undetected lesions were: fatty in 3 (1.8%; scattered fibroglandular density in 40 (24.3%, heterogeneously dense in 91 (55.1% and dense in 31 (18.8% cases. In breasts with an almost entirely fatty pattern, Mx sensitivity was 100%, while in fibroglandular or dense pattern it was reduced to 45

    Aim: The aim of this study is to assess the value of carbohydrate antigen 549 (CA 549) in diagnosis and follow-up of breast carcinoma and compare CA 549 with other tumoral markers. Methods: A. We have studied 1230 determinations of CA 549 corresponding to 460 patients (3 male) with confirmed or suspected diagnosis of breast carcinoma. CA 549 was determined using a radioimmunometric assay that use a 'sandwich' technique on solid phase. B. To compare CA 549 with other tumoral markers we have reviewed the case history of 40 patients with advanced breast carcinoma. The tumoral markers studied were: CEA, CA 19.9, CA 15.3 and CA 549. C. We have performed a correlation study between the different tumoral markers on 124 evaluations and calculated the Pearson's correlation coefficient. Results: In the group of confirmed or suspected diagnosis of breast carcinoma (n=460): 187 patients (40,65%) showed pathological levels of CA 549. In the group of patients with advanced breast carcinoma (36 patients with metastasis and 4 with advanced local extension). the results of the different tumoral markers are presented. The Pearson's correlation coefficient between CA 549 and CA 15.3 was 0.814, while no correlation was found in the remaining markers. Conclusion: CA 549 is a good marker of progression or persistence of tumoral disease in breast carcinoma

    The present is an overview of recent data that describes the genetic underpinnings of the suppression of cancer metastasis. Despite the explosion of new information about the genetics of cancer, only six human genes have thus far been shown to suppress metastasis functionally. Not all have been shown to be functional in breast carcinoma. Several additional genes inhibit various steps of the metastatic cascade, but do not necessarily block metastasis when tested using in vivo assays. The implications of this are discussed. Two recently discovered metastasis suppressor genes block proliferation of tumor cells at a secondary site, offering a new target for therapeutic intervention

    Medullary carcinoma of the breast is a rare type breast cancer, and shows peculiar clinical features. In a series of 460 cases of breast cancer operated on at the hospital from 1975 to 2004, twelve (2.6%) cases were diagnosed as medullary carcinoma of the breast by postoperative pathological study. When the specimens from the twelve tumors were reevaluated according to the Ridolfi's subtype classification, six tumors were classified into typical medullary carcinoma (TMC) and the remaining six tumors into atypical medullary carcinoma (AMC). On mammography these tumors were visualized as homogeneously enhancing oval masses without calcification and the boundary was comparatively well-defined. US demonstrated well-defied masses with a heterogeneous, hypoechoic texture and with reinforcement of posterior echoes. The rate of lymph node metastasis was 33.3% in medullary carcinomas which was not significantly different from that of infiltrative ductal carcinomas experienced during the same period. The rate of a positivity of a hormone receptor was 8.3% in medullary carcinomas which was low in predominance in comparison with that of infiltrative ductal carcinomas. The positive rate for a HER2/neu (above2+) by the IHC method was 58%. An average observation period is 11 years, and all patients are alive. (author)

    2005-04-01

    Full Text Available In most of the cases, breast carcinoma is the primary tumor of the female population. Having in mind a well known fact that the best and most effective way for its terminal eradication is an early treatment upon its localization, tremendous efforts are being made to make an early diagnosis of breast cancer. The sooner the better. The early and precise diagnosis is of crucial importance in the application of adequate therapy, thus achieving more successful outcome with the possibility of complete healing. It is established on the basis of a routine clinical examination and supplementary diagnostic methods. Supplementary diagnostic methods may be noninvasive, minimally invasive and invasive. Noninvasive diagnostic methods are: mammography, xeromammography, ultrasound, thermography, galactography, pneumocystography, computerized mammography, translumination scintigraphy, magnetic resonance and tomography with positive emission.Minimally invasive diagnostic methods are: ductal lavage, aspiration cytology performed with a thin needle and “tru-cut” biopsy.Invasive methods include: biopsy “ex tempore” and “sentinel lymph node” biopsy.Great importance is attributed to the preoperative diagnosis with the help of which we are able to establish the precise and timely diagnosis.

    Metaplastic carcinoma, an uncommon subtype of breast cancer, is part of the spectrum of basal-like, triple receptor-negative breast carcinomas. The present study examined 20 surgical specimens of metaplastic breast carcinomas, for the presence of high-risk Human papillomavirus (HPV), which is suspected to be a potential carcinogenic agent for breast carcinoma. Mastectomy specimens from patients harboring metaplastic breast carcinoma, as defined by the World Health Organization (WHO), and who attended the Instituto Nacional de Cancerologia in Mexico City, were retrieved from the files of the Department of Pathology accumulated during a 16-year period (1995–2008). Demographic and clinical information was obtained from patients’ medical records. DNA was extracted from formalin-fixed, paraffin-embedded tumors and HPV type-specific amplification was performed by means of Polymerase chain reaction (PCR). Quantitative Real-time (RT) PCR was conducted in HPV positive cases. Statistically, the association of continuous or categorical variables with HPV status was tested by the Student t, the Chi square, or Fisher’s exact tests, as appropriate. High-risk HPV DNA was detected in eight (40%) of 20 metaplastic breast carcinomas: seven (87.5%) HPV-16 and one (12.5%) HPV-18. Mean age of patients with HPV-positive cases was 49 years (range 24–72 years), the same as for HPV-negative cases (range, 30–73 years). There were not striking differences between HPV + and HPV– metaplastic carcinomas regarding clinical findings. Nearly all cases were negative for estrogen, progesterone and Human epidermal growth factor receptor 2 (HER2), but positive for Epidermal growth factor receptor (EGFR). High-risk HPV has been strongly associated with conventional breast carcinomas, although the subtle mechanism of neoplastic transformation is poorly understood. In Mexican patients, the prevalence of HPV infection among metaplastic breast carcinomas is higher than in non-metaplastic ones

    Full Text Available Abstract Introduction Male breast cancer (MBC is a rare, yet potentially aggressive disease. Although literature regarding female breast cancer (FBC is extensive, little is known about the etiopathogenesis of male breast cancer. Studies from our laboratory show that MBCs have a distinct immunophenotypic profile, suggesting that the etiopathogenesis of MBC is different from FBCs. The aim of this study was to evaluate and correlate the immunohistochemical expression of cell cycle proteins in male breast carcinoma to significant clinico-biological endpoints. Methods 75 cases of MBC were identified using the records of the Saskatchewan Cancer Agency over 26 years (1970-1996. Cases were reviewed and analyzed for the immunohistochemical expression of PCNA, Ki67, p27, p16, p57, p21, cyclin-D1 and c-myc and correlated to clinico-biological endpoints of tumor size, node status, stage of the disease, and disease free survival (DFS. Results Decreased DFS was observed in the majority of tumors that overexpressed PCNA (98%, p = 0.004. The overexpression of PCNA was inversely correlated to the expression of Ki67 which was predominantly negative (78.3%. Cyclin D1 was overexpressed in 83.7% of cases. Cyclin D1 positive tumors were smaller than 2 cm (55.6%, p = 0.005, had a low incidence of lymph node metastasis (38.2%, p = 0.04 and were associated with increased DFS of >150 months (p = 0.04. Overexpression of c-myc (90% was linked with a higher incidence of node negativity (58.3%, p = 0.006 and increased DFS (p = 0.04. p27 over expression was associated with decreased lymph node metastasis (p = 0.04. P21 and p57 positive tumors were related to decreased DFS (p = 0.04. Though p16 was overexpressed in 76.6%, this did not reach statistical significance with DFS (p = 0.06 or nodal status (p = 0.07. Conclusion Aberrant cell cycle protein expression supports our view that these are important pathways involved in the etiopathogenesis of MBC. Tumors with overexpression

    Full Text Available Background: Breast cancer is the commonest cancer and 2nd most common cause of cancer death among women worldwide. Histologically breast cancer can be divided into Invasive Lobular Carcinoma (ILC, Invasive Ductal Carcinoma (IDC and others. ILC has its own unique patient’s demographic, histological appearance, imaging characteristics and clinical outcome. Previous published study has shown that ILC has better overall survival compared to IDC. Sadly, despite being so common, there is still lack of study comparing ILC and IDC in Malaysia setting. Methods: 5225 of patients diagnosed with ILC and IDC were managed in University Malaya Medical Center within 1993 to 2013 has been included in this study. Chi square test were performed to determine the demographic and clinical factors associated with ILC and IDC. Kaplen-Meier method was used to obtain overall survival of these patients. Through a Cox regression analysis, mortality in patients diagnosed with ILC and IDC were identified, by adjusting the possible confounding factors. Results: ILC is more common in elderly compared to younger patients. There is no association between ethnicity and types of invasive carcinoma. Patients with ILC were more likely to have lymph nodes involvement (p = 0.001, estrogen receptor positive (p = 0.001, absent of lymphovascular invasion (p = 0.028, mastectomy (p = 0.022 and hormonal therapy (p = 0.002 compared to IDC and it is statistically significant. Nevertheless, survival was not significantly different between ILC and IDC; 5-year OS; 77.4% (95% CI 77.34 to 77.46 and 71.3% (95% CI 71.29 to 71.30, respectively; the 10 year OS; 52.2% (95% CI 52.13 to 52.27 and 49.7% (95% CI 49.68 to 49.72, respectively. The adjusted hazard ratio comparing ILC and IDC using Cox regression was 1.21 (0.85 to 1.72 showing there is no significant difference between patients presented with ILC and IDC in terms of survival.

    2011-02-01

    Full Text Available The transfer of peptides identified through the phage display technology to clinical applications is difficult. Major drawbacks are the metabolic degradation and label instability. The aim of our work is the optimization of DUP-1, a peptide which was identified by phage display to specifically target human prostate carcinoma. To investigate the influence of chelate conjugation, DOTA was coupled to DUP-1 and labeling was performed with 111In. To improve serum stability cyclization of DUP-1 and targeted D-amino acid substitution were carried out. Alanine scanning was performed for identification of the binding site and based on the results peptide fragments were chemically synthesized. The properties of modified ligands were investigated in in vitro binding and competition assays. In vivo biodistribution studies were carried out in mice, carrying human prostate tumors subcutaneously. DOTA conjugation resulted in different cellular binding kinetics, rapid in vivo renal clearance and increased tumor-to-organ ratios. Cyclization and D-amino acid substitution increased the metabolic stability but led to binding affinity decrease. Fragment investigation indicated that the sequence NRAQDY might be significant for target-binding. Our results demonstrate challenges in optimizing peptides, identified through phage display libraries, and show that careful investigation of modified derivatives is necessary in order to improve their characteristics.

    Full Text Available Breast metastases are a relatively rare condition and account for approximately 0.5–2% of all breast tumors. Recognition of metastatic tumors in the breast is important because it would prevent unnecessary mutilating surgery and would lead to appropriate treatment of the primary tumor. Breast metastases from medullary thyroid cancer (MTC are very rare with only 21 reported cases in the literature. Some MTCs mimic primary invasive lobular carcinoma of the breast histopathologically and radiologically, making the distinction between the two diagnostically challenging. We present the case of a 45-year-old female presenting with a lump breast, which was later found out to be metastasis from medullary carcinoma thyroid.

    Salivary duct carcinoma (SDC) is a high-grade salivary gland malignancy with great morphological resemblance to invasive ductal carcinoma (IDC) of the breast. Rarely, female patients may have a past history of both SDC and IDC. When these patients present with distant metastasis, accurate identification of the primary tumor is particularly difficult. Additionally, rare metastasis of SDC to the breast and IDC to the salivary (parotid) gland can also present a diagnostic challenge. Our aim was to develop an immunohistochemical panel that reliably distinguishes SDC from IDC. We included all SDCs diagnosed from 1989 to 2016 (23 cases) and 29 treatment naïve and histologically similar IDCs. All cases were stained with androgen receptor (AR), estrogen receptor-alpha (ER-α), progesterone receptor (PR), HER-2, CK5/6, p63, and beta-catenin. The great majority (> 90%) of both SDCs and IDCs reacted positively to AR. The main discrepancy in the immunohistochemical profiles was a distinctly different reactivity to ER-α, PR and HER-2. While 28 IDCs (96.6%) reacted positively to ER-α and/or PR, the majority expressing both (82.8%) with a moderate to strong staining intensity, only 2 SDCs expressed ER-α (8.7%) and 5 others expressed PR (21.7%) with only one case expressing both (P value SDC (34.8%) were positive for HER-2 while none of the IDCs were positive (P value SDC from IDC. Positive reactivity to ER-α, PR or both and negative HER-2 favors a diagnosis of IDC while ER-α, PR negative, HER-2 positive tumors are more likely SDC.

    Full Text Available Pure primary squamous cell carcinoma of the breast (SCCB represents around 0.1% of breast carcinomas. Diagnosis requires independence from adjacent skin without metastatic disease. SCCB is often large at presentation with nonspecific mammographic and ultrasound findings. It is typically hormone receptor negative and aggressive. Mastectomy and adjuvant chemotherapy is the most common treatment, although treatment guidelines are not well established. We present a case of pure primary SCCB detected by high risk screening mammogram and treated with breast conserving surgery, chemotherapy, and radiation. We discuss clinical, radiologic, and pathologic findings.

    At time of presentation, fewer than 10% of patients have metastatic breast cancer. The most common sites of metastasis in order of frequency are bone, lung, pleura, soft tissue, and liver. Breast cancer metastasis to the uterus or gallbladder is rare and has infrequently been reported in the English literature. A 47 year old female with a recent history of thrombocytopenia presented with abnormal vaginal bleeding. Pelvic ultrasound revealed multiple uterine fibroids and endometrial curettings revealed cells consistent with lobular carcinoma of the breast. Breast examination revealed edema and induration of the lower half of the right breast. Biopsy of the right breast revealed invasive lobular carcinoma. Bone marrow aspiration obtained at a previous outpatient visit revealed extensive involvement by metastatic breast carcinoma. Shortly after discharge, the patient presented with acute cholecystitis and underwent cholecystectomy. Microscopic examination of the gallbladder revealed metastatic infiltrating lobular carcinoma. The final diagnosis was invasive lobular carcinoma of the right breast with metastasis to the bone marrow, endometrium, gallbladder, regional lymph nodes, and peritoneum. The growth pattern of invasive lobular carcinoma of the breast is unique and poses a challenge in diagnosing the cancer at an early stage. Unlike other types of breast cancer, it tends to metastasize more to the peritoneum, ovary, and gastrointestinal tract. Metastasis to the endometrium or gallbladder is rare. Metastatic spread should be considered in the differential diagnosis of patients with invasive lobular breast carcinoma presenting with abnormal vaginal bleeding or acute cholecystitis.

    ERBB2 and ERBB3 somatic gain-of-function mutations, which may be targeted by anti-ERBB2 therapies, were reported by high-throughput sequencing studies in 1% and 2% of invasive breast cancers respectively. Our study aims to determine ERBB2 and ERBB3 mutations frequencies in grade 3 and/or ERBB2-positive invasive lobular breast carcinomas (ILC). All the 529 ILC surgically-excised registered at Institut Curie in the years 2005 to 2008 were reviewed. Thirty-nine grade 3 ERBB2-negative ILC and 16 ERBB2-positive ILC were retrieved and subjected to Sanger sequencing of the ERBB2 and ERBB3 activation mutation hotspots (ERBB2: exons 8, 17, 19, 20, 21; ERBB3: exons 3, 6, 7, 8). Among the 39 grade 3 ERBB2-negative ILC, six tumors were found to have at least one detectable ERBB2 activating mutation (incidence rate: 15%, 95%CI [4%-27%]). No ERBB2 mutation was found among the 16 ERBB2-positive ILC. No ERBB3 mutation was found in any of the 55 ILC. ERBB2 mutations were statistically associated with solid ILC features (p=0.01). Survival analyses showed no significant prognostic impact of ERBB2 mutations. Our study demonstrates that high grade ERBB2-negative ILC display a high frequency of ERBB2 mutations, and should be subjected to systematic genetic screening.

    2017-01-01

    Full Text Available Vulvar carcinoma is a rare disease that accounts for 3–5% of all gynecologic malignancies. Breast represents an unusual site of metastasis and only a few cases are reported. We describe the first case of bilateral metastatic breast carcinoma of vulvar origin, at an 80-year-old female patient. Six months after treatment of her primary disease, she presented with bilateral metastatic squamous cell breast carcinoma. Diagnosis was based on clinical, radiological, and histological facts. Breast although rare is another potential site of metastasis in vulvar cancer and thus mammary gland examination should be considered in the follow-up of these patients. Differential diagnosis between primary and metastatic lesions is of utmost importance for appropriate management.

    Adenoid cystic carcinoma of the breast is a rare neoplasm, accounting for only 0.1% of all malignant breast tumours. It is more common in women in the sixth decade of their lives and often in the sub areolar area. The clinical criteria is not specific and the radiographic examination showed a benign-appearing tumour. The preoperative diagnosis is possible with fine-needle aspiration cytology. The diagnosis is made by histological examination, presented a difficult differential diagnosis with cribriform carcinoma; so it is necessary to use histochemical or immunohistochemical techniques. The treatment is not well established. It consists of lumpectomy with radiation or mastectomy. Compared to other locations, adenoid cystic carcinoma of the breast has a favorable prognosis. Lymph node involvement or distant metastases seldom occur. The aim of our study is to describe the epidemiological, clinico pathological characteristics, the treatment and the prognosis of this rare type of breast tumour. (authors)

  15. Case report of gastric outlet obstruction from metastatic lobular breast carcinoma.

    2015-09-25

    The most common malignancy to cause gastric outlet obstruction is primary gastric adenocarcinoma and it is followed by carcinoma of the pancreas and gallbladder. Herein, we report a case of gastric outlet obstruction secondary to metastatic lobular breast carcinoma. Fifty-seven year old Caucasian female with recently diagnosed metastatic lobular breast carcinoma to skin was referred to gastroenterology for evaluation of dyspepsia and dysphagia. She has past medical history significant for acid reflux and Clostridium difficile colitis. Computed tomography of her abdomen showed diffused bowel wall thickening without evidence of bowel obstruction. Due to persistent abdominal pain, an upper endoscopy was performed. The upper endoscopy showed gastritis and gastric stenosis in the gastric antrum. These lesions were biopsied and dilated with a balloon dilator. The biopsy of the gastric antrum later showed a metastatic carcinoma of breast origin with typical tumor morphology and immune-phenotype. Differentiating metastatic breast carcinoma from primary gastric adenocarcinoma cannot be done using histological examination alone. Immunohistochemistry is needed to differentiate the two based on staining for estrogen and progesterone receptors. The presence of gross cystic disease fluid protein 15 is also suggestive of metastatic breast carcinoma. The stomach has a significant capacity to distend (up to 2-4 L of food) and malignant gastric outlet obstruction is often undetected clinically until a high-grade obstruction develops. Our case demonstrates valuable teaching point in terms of broadening our differentials for gastric outlet obstruction. When patients present with gastric outlet obstruction, both non-malignant and malignant causes of gastric outlet obstruction should be considered. Once adenocarcinoma has been determined to be the cause of gastric outlet obstruction, further immunohistochemistry is needed to differentiate breast carcinoma from other carcinomas.

    The expression of ANO1 is considered to have diagnostic specificity for gastrointestinal stromal tumors. However, its function as a calcium-activated chloride channel suggests that the expression of ANO1 is not restricted to gastrointestinal stromal tumors. Recently, it has been reported that ANO1 has roles in the progression of human malignant tumors. However, the role of ANO1 in breast carcinoma has been controversial. Therefore, we investigated the expression of ANO1 in 139 breast carcinoma patients and the role of ANO1 in vitro . The immunohistochemical expression of ANO1 was significantly associated with the expression of β-catenin, cyclin D1, MMP9, snail, and E-cadherin. Especially, ANO1 expression was an independent indicator of poor prognosis of shorter overall survival and relapse-free survival of breast carcinoma patients by multivariate analysis. In MCF7 and MDA-MB-231 breast carcinoma cells, inhibition of ANO1 with T16Ainh-A01 or siRNA for ANO1 significantly suppressed the proliferation of cells. Knock-down of ANO1 with siRNA induced G0/G1 cell cycle arrest and significantly inhibited the invasiveness of breast carcinoma cells. Knock-down of ANO1 decreased the expression of β-catenin, cyclin D1, MMP9, snail, and N-cadherin, and increased the expression of E-cadherin. In conclusion, this study demonstrates that ANO1 expression is an indicator of poor prognosis of breast carcinoma patients and suggests that ANO1 might be a therapeutic target for breast carcinoma patients with ANO1-positive tumors and poor prognosis.

    The enhancing area surrounding breast carcinoma on MR mammography is correlated with findings from pathological examination. We studied 194 patients with breast cancer who underwent preoperative MR mammography. Of all malignant lesions presenting with an enhancing surrounding area on MR mammography, morphologic features including long spicules, a ductal pattern, diffuse enhancement or nodules were evaluated and compared with histopathological examination. A double breast coil was used; we performed a 3D FLASH sequence with contiguous coronal slices of 2 mm, before and after injection of 0.2 mmol/kg GD-DTPA, and subtraction images were obtained. In total, 297 malignant lesions were detected at MR mammography and 101 of them had one or more types of enhancing surrounding area. In 49 of the 53 cancers with long spicules and in 49 of the 55 cancers with surrounding ductal pattern of enhancement, pathological examination showed in situ and/or invasive carcinoma. Multiple nodules adjacent to the carcinoma were seen in 20 patients and corresponded with six cases of invasive and ten cases of ductal in situ carcinoma. A diffuse enhancing area next to a mass was seen in ten patients and consisted of carcinoma in all cases: seven in situ and three invasive carcinomas. Enhancing areas including long spicules, a ductal pattern, noduli, or diffuse enhancement surrounding a carcinoma corresponded with in situ or invasive extension of the carcinoma in 92.5, 89, 80 and 100% of cases, respectively.

    Thyroid carcinoma is usually indolent with good prognosis, as compared to other malignancy. Distant metastases from thyroid cancer are rare and usually manifest as multiple lesions especially in lungs, bones and lymph nodes, in advanced stages of the disease. Metastasis to the breast from thyroid carcinoma is extremely rare, with about 16 cases reported in the English literature. Herein, we reported a case of metastatic poorly differentiated thyroid carcinoma, which presented as 2 breast masses in a 72-year-old woman, 6 years after total thyroidectomy for papillary thyroid carcinoma. Although the computed tomography (CT) and ultrasonography (USG) image findings are nonspecific oval mass with circumscribed or partially indistinct margin, metastases from thyroid cancer should be included in the differential diagnosis when recurrence of thyroid carcinoma is suspected. Also, fusion images of CT and USG are helpful to the radiologists in localizing the targeted lesion and conducting accurate USG-guided biopsy.

    2017-01-01

    Full Text Available Background: In India, the number of new breast cancer cases is about 115,000 per year and this is expected to rise to 250,000 new cases per year by 2015. It needs to be noted that breast cancer is leading in the age groups of 15–34 years which is a cause of concern as this denotes the need for educative and awareness programs targeting younger members of the society, to implement early practices of breast examination. This study was carried out with the intention of assessing the level of knowledge and awareness of carcinoma breast and breast self-examination (BSE in female college students. Materials and Methods: This cross-sectional study was carried out in a well-known basic sciences college. After the pretest questionnaire was given, an awareness talk was given about breast cancer and BSE. A posttest questionnaire was administered. The data of pre- and post-test were collected and analyzed using SPSS. Results: Pretest and posttest were collected from 1030 students. The age of the study participants was ranged between 18 and 23 years. Most of them were aware of breast carcinoma, but half of them thought breast cancer affects the elderly. Regarding different aspects studied, 58% had a knowledge of at least one of the symptoms and 59% knew at least one of the risk factors for breast carcinoma. Only 185 (18% women knew about BSE and 107 women practice it. Conclusions: This study concluded that the awareness of the breast cancer was good but the knowledge of signs and BSE was poor, which is utmost important for early detection and in reduction of mortality.

    Aberrant expression of E-cadherin has been associated with the development of metastases in patients with breast cancer. Even though the expression of E-cadherin has been studied in primary breast tumors, little is known about its expression at the distant metastatic sites. We investigate the relationship between E-cadherin expression in primary breast carcinoma and their distant, non-nodal metastases. Immunohistochemical analysis of E-cadherin was performed in tissues from 30 patients with primary invasive breast carcinoma and their distant metastases. E-cadherin expression was evaluated as normal or aberrant (decreased when compared with normal internal positive controls, or absent). Twenty-two (73%) invasive carcinomas were ductal, and eight (27%) were lobular. Of the primary invasive ductal carcinomas, 55% (12/22) had normal E-cadherin expression and 45% (10/22) had aberrant expression. All of the metastases expressed E-cadherin with the same intensity as (12 tumors) or with stronger intensity than (10 tumors) the corresponding primaries. Of the invasive lobular carcinomas, one of eight (12%) primary carcinomas and none of the metastases expressed E-cadherin in the cell membranes, but they accumulated the protein in the cytoplasm. Aberrant E-cadherin expression is frequent in invasive ductal carcinomas that progress to develop distant metastases. Distant metastases consistently express E-cadherin, often more strongly than the primary tumor. Invasive lobular carcinomas have a different pattern of E-cadherin expression, suggesting a different role for E-cadherin in this form of breast carcinoma

Invasive ductal carcinoma was the most common histological type (n = 47; 79.7%. At PET/CT, 53 (89.8% of the lesions demonstrated anomalous concentrations of 18F-FDG, with maximum SUV ranging from 0.8 to 23.1 (mean: 5.5. A statistically significant association was observed between higher values of maximum SUV and histological type, histological grade, molecular subtype, tumor diameter, mitotic index and Ki-67 expression. Conclusion PET/CT performed with specific protocol for assessment of breasts has demonstrated good sensitivity and was associated with relevant histological/immunohistochemical factors related to aggressiveness and prognosis of breast carcinomas.

    Neuroendocrine carcinoma of the breast - a very recent diagnosis, which was not recognized by WHO until 2003 - has lately been the subject of increasing attention. It is defined as a primary breast cancer with morphologic features similar to other types of neuroendocrine tumors of the lung......, apparent limitations of the WHO definition appear to influence diagnosis. Here, we present our own results obtained from 13 cases and furthermore review previous reports with particular reference to incidence, clinical, histological, and prognostic features....

  3. Automated quantification of aligned collagen for human breast carcinoma prognosis

    2014-01-01

    Full Text Available Background: Mortality in cancer patients is directly attributable to the ability of cancer cells to metastasize to distant sites from the primary tumor. This migration of tumor cells begins with a remodeling of the local tumor microenvironment, including changes to the extracellular matrix and the recruitment of stromal cells, both of which facilitate invasion of tumor cells into the bloodstream. In breast cancer, it has been proposed that the alignment of collagen fibers surrounding tumor epithelial cells can serve as a quantitative image-based biomarker for survival of invasive ductal carcinoma patients. Specific types of collagen alignment have been identified for their prognostic value and now these tumor associated collagen signatures (TACS are central to several clinical specimen imaging trials. Here, we implement the semi-automated acquisition and analysis of this TACS candidate biomarker and demonstrate a protocol that will allow consistent scoring to be performed throughout large patient cohorts. Methods: Using large field of view high resolution microscopy techniques, image processing and supervised learning methods, we are able to quantify and score features of collagen fiber alignment with respect to adjacent tumor-stromal boundaries. Results: Our semi-automated technique produced scores that have statistically significant correlation with scores generated by a panel of three human observers. In addition, our system generated classification scores that accurately predicted survival in a cohort of 196 breast cancer patients. Feature rank analysis reveals that TACS positive fibers are more well-aligned with each other, are of generally lower density, and terminate within or near groups of epithelial cells at larger angles of interaction. Conclusion: These results demonstrate the utility of a supervised learning protocol for streamlining the analysis of collagen alignment with respect to tumor stromal boundaries.

    Male breast cancer is rare, comprising only 1% of all mammary cancers; invasive ductal carcinoma is by far the commonest subtype in both men and women. Though lobular breast cancer is the second most common subtype seen in women, such cancers are extremely uncommon in men, and this is likely related to the lack of lobular development in the male breast. Thus, due to the rarity of this subtype among breast cancers, compounded by the overall rarity of breast cancer in men, current understanding of the pathogenesis of this disease and its management is largely derived from case series and extrapolation of information from the larger cohort of female patients. This paper provides a systematic review on invasive lobular carcinoma of the male breast in the context of an illustrative case study. A comprehensive analysis of the National Cancer Institute’s Surveillance, Epidemiology, and End Results Data 1973–2013 leading to an exploration of the pathogenesis, epidemiology, clinical presentation, diagnosis, tumor characteristics, and management of lobular breast carcinoma in men is also discussed. Lobular subtype of breast cancer remains an enigmatic elusive disease that needs additional research to unravel its overall pathogenesis and molecular profile to provide insight for improved therapeutic management options.

    Full Text Available Abstract Background Lobular breast carcinoma usually shows poor responsiveness to chemotherapies and often lacks targeted therapies. Since FGFR1 expression has been shown to play pivotal roles in primary breast cancer tumorigenesis, we sought to analyze the status of FGFR1 gene in a metastatic setting of lobular breast carcinoma, since promising FGFR1 inhibitors has been recently developed. Methods Fifteen tissue metastases from lobular breast carcinomas with matched primary infiltrative lobular breast carcinoma were recruited. Eleven cases showed loco-regional lymph-nodal and four haematogenous metastases. FGFR-1 gene (8p12 amplification was evaluated by chromogenic in situ hybridization (CISH analysis. Her-2/neu and topoisomerase-IIα gene status was assessed. E-cadherin and Hercept Test were also performed. We distinguished amplification (>6 or cluster of signals versus gains (3–6 signals of the locus specific FGFR-1 gene. Results Three (20% primary lobular breast carcinomas showed >6 or cluster of FGFR1 signals (amplification, six cases (40% had a mean of three (range 3–6 chromogenic signals (gains whereas in 6 (40% was not observed any abnormality. Three of 15 metastasis (20% were amplified, 2/15 (13,4% did not. The ten remaining cases (66,6% showed three chromogenic signals. The three cases with FGFR-1 amplification matched with those primary breast carcinomas showing FGFR-1 amplification. The six cases showing FGFR-1 gains in the primary tumour again showed FGFR-1 gains in the metastases. Four cases showed gains of FGFR-1 gene signals in the metastases and not in the primary tumours. Her-2/neu gene amplification was not observed in all cases but one (6% case. Topoisomerase-IIα was not amplified in all cases. Conclusions 1 a subset of metastatic lobular breast carcinoma harbors FGFR-1 gene amplification or gains of chromogenic signals; 2 a minor heterogeneity has been observed after matching primary and metastatic carcinomas; 3 in the

    Full Text Available Malignant tumors of the oral cavity which are metastatic are very rare and consist of 1% of malignancies of the oral cavity. Numbness or paresthesia of the lower lip or the chin is the main feature of presence of metastasis in the jaw. Our patient was a 38 year old woman with chief complaint of pain in the right half of her face, jaw and teeth. Her medical history revealed a radical mastectomy with lymphadenectomy in the left breast because of invasive ductal carcinoma grade II/III and stage IIIA (T2N2M0 without distant metastasis, followed by chemotherapy (before and after the surgery and radiotherapy two years ago. Following complementary examinations a malignant bone lesion in particular osteosarcoma was suspected. According to this evidence, possibility of early diagnosis of malignant tumors is very important for dentists and maxillofacial surgeons. Symptoms such as paresthesia of the lip and chin is very helpful in differential diagnosis of metastatic lesions from other similar clinical cases especially in patients with history of malignancies which minimize surgical and mental injuries and increase life expectancy of patients.

    In the early period of the pregnancy, the radiological protection of the unborn child is of particular concern. In several reports dose thresholds for deterministic effects as well as dose values that increase the probability of stochastic effects have been established. The aim of this article was to estimate the peripheral dose (PD) in order to evaluate the absorbed dose in utero for breast carcinoma treatment related to the radiotherapy procedures established in our hospital. The treatment was simulated using an anthropomorphic phantom Alderson-Rando, and two similar treatment planning with and without wedges were performed, taken into account the average field parameters used in 300 treatment planning patients. The PD values were determined with a NE 2571 ionization chamber in a General Electric linac for the treatments considered. Experimental measures provided dose in utero values slightly higher than 5 cGy, dose threshold established in some articles for radioinduced effects in the fetus. The planning system underestimated the PD values and no significant influence with the use of wedges was found. (author)

  9. An Unusual Clinical Presentation of Gastrointestinal Metastasis From Invasive Lobular Carcinoma of Breast

    Full Text Available Introduction. We present an unusual case of metastatic lobular breast carcinoma. Typical areas of metastasis include bone, gynecological organs, peritoneum, retroperitoneum, and gastrointestinal (GI tract, in order of frequency. With regard to GI metastasis, extrahepatic represents a rare site. Case. Two years after being diagnosed with invasive lobular breast carcinoma, a 61-year-old female complained of 3 months of nonspecific abdominal pain and diarrhea. A colonoscopy revealed 5 tubular adenomatous polyps in the ascending and transverse colon. Contrast computed tomography (CT of the abdomen and pelvis was done 7 months after the colonoscopy to further evaluate persistent diarrhea. The CT results were consistent with infectious or inflammatory enterocolitis. Despite conservative management, symptoms failed to improve and a repeat diagnostic colonoscopy was obtained. Random colonic biopsies revealed metastatic high-grade adenocarcinoma of the colon. Discussion. Metastatic lobular breast carcinoma to the GI tract can distort initial interpretation of endoscopic evaluation with lesions mimicking inflammation. The interval between discovery of GI metastasis and diagnosis of lobular breast cancer can vary widely from synchronous to 30 years; however, progression is most often much sooner. Nonspecific symptoms and subtle appearance of metastatic lesions may confound the diagnosis. A high index of suspicion is needed for possible metastatic spread to the GI tract in patients with a history of invasive lobular breast carcinoma. Perhaps, patients with nonspecific GI symptoms should have an endoscopic examination with multiple random biopsies as invasive lobular carcinoma typically mimics macroscopic changes consistent with colitis.

    Full Text Available Abstract Background Cowden Syndrome (CS patients with germ line point mutations in the PTEN gene are at high risk for developing breast cancer. It is believed that cells harboring these mutant PTEN alleles are predisposed to malignant conversion. This article will characterize the biochemical and biological properties of a mutant PTEN protein found in a commonly used metastatic breast cancer cell line. Methods The expression of PTEN in human breast carcinoma cell lines was evaluated by Western blotting analysis. Cell line MDA-MB-453 was selected for further analysis. Mutation analysis of the PTEN gene was carried out using DNA isolated from MDA-MB-453. Site-directed mutagenesis was used to generate a PTEN E307K mutant cDNA and ectopic expressed in PC3, U87MG, MCF7 and Pten-/- mouse embryo fibroblasts (MEFS. Histidine (His-tagged PTEN fusion protein was generated in Sf9 baculovirus expression system.

The intracellular localization of PTEN E307K was determined by subcellular fractionation experiments. The ability of PTEN E307K to alter cell growth, migration and apoptosis was analyzed in multiple PTEN-null cell lines. Results We found a mutation in the PTEN gene at codon 307 in MDA-MB-453 cell line.

    Fibroadenoma (FA) is the most common benign tumor of the female breast and several studies have reported that women with it have increased risk of breast cancer. While the ductal carcinoma in situ (DCIS) is a very early form of breast cancer. Thus, early detections of FA and DCIS are critical for improving breast tumor outcome and survival. In this paper, we use multiphoton microscopy (MPM) to obtain the high-contrast images of fresh, unfixed, unstained human breast specimens (normal breast tissue, FA and DCIS). Our results show that MPM has the ability to identify the characteristics of FA and DCIS including changes of duct architecture and collagen morphology. These results are consistent with the histological results. With the advancement of MPM, the technique has potential ability to serve as a real-time noninvasive imaging tool for early detection of breast tumor.

    Invasive lobular carcinoma of the breast is known to produce intracellular mucin and has been recognized in single-case reports to show extracellular mucin production, as well. This latter morphology is not only rare but must also be under- or misdiagnosed. The aim was to better characterize this entity. Cases of lobular cancers demonstrating extracellular mucin formation were identified in a multi-institutional effort and their clinical and morphologic features were assessed. Immunohistochemistry was used to characterize the E-cadherin-membrane complex, neuroendocrine differentiation, and to some extent, mucin formation. All but one of the eight cases occurred in postmenopausal patients. Extracellular mucin production was present in 5 to 50% of the tumour samples and rarely also appeared in nodal and distant metastases. The tumours were completely E-cadherin negative and showed cytoplasmic p120 positivity. The majority (n = 6/8) was also completely negative for β-catenin, but two tumours displayed focal β-catenin positivity in the mucinous area. MUC1 and MUC2 expression was observed in all and 7/8 tumours, respectively; neuroendocrine differentiation was present in only one. Invasive lobular carcinoma with extracellular mucin formation is a rare morphologic variant of lobular carcinoma prone to be misdiagnosed and warranting further studies.

    Full Text Available Lobular breast carcinoma involving the colon is a rare condition. In most cases reported in the literature, metastases are detected after a 20-year latency period after the initial diagnosis. Here we describe a case in which metastatic lobular breast carcinoma and colonic metastasis were simultaneously diagnosed—with only 4 days between the two diagnoses. A 55-year-old woman underwent mammography and colonoscopy in the setting of the National Cancer Screening Program. A malignant nodule in the left breast was detected, and core-biopsy revealed an invasive lobular carcinoma. Simultaneously, numerous intestinal micropolyps were sampled. Histological examination of the latter showed tumor cells growing in cords and presenting signet-ring appearance, thereby confirming metastatic breast carcinoma. In cases such as the one described here, pathological diagnosis can be extremely difficult and deep biopsies are required. Metastatic breast cancer involving the colon can be considerably underestimated because of the unspecificity of the clinical manifestations, the long latency period, and diverse radiological findings that can lead to misdiagnosis. We conclude that clinicians should rule out intestinal metastasis in patients diagnosed with breast cancer, especially the lobular type, and presenting non-specific abdominal symptoms.

    In the past three decades, the detection rate of ductal carcinoma in situ of the breast has dramatically increased due to breast screening programs. As a consequence, about 20% of all breast cancer cases are detected in this early in situ stage. Some ductal carcinoma in situ cases will progress to invasive breast cancer, while other cases are likely to have an indolent biological behavior. The presence of tumor-infiltrating lymphocytes is seen as a promising prognostic and predictive marker in invasive breast cancer, mainly in HER2-positive and triple-negative subtypes. Here, we summarize the current understanding regarding immune infiltrates in invasive breast cancer and highlight recent observations regarding the presence and potential clinical significance of such immune infiltrates in patients with ductal carcinoma in situ. The presence of tumor-infiltrating lymphocytes, their numbers, composition, and potential relationship with genomic status will be discussed. Finally, we propose that a combination of genetic and immune markers may better stratify ductal carcinoma in situ subtypes with respect to tumor evolution.

    The first reference concerning the multiple primary malignant neoplasms was made by Bilroth, 1880 and since then a large number of studies have been published. Furthermore, an increasing incidence of simultaneous cancers are currently observed (16,18). At the same time, several retrospective populational studies evidenced the association between breast and endometrium carcinoma. It is well known that both uterus and breast are hormone-dependent organs and are likely to be influenced by the same oncogenic stimulus, either of endocrine nature or dietary origin (2, 3, 14). The risk of developing endometrial carcinoma is higher in patients already affected by breast neoplasm and is much more evident in older women within the first five years following the diagnosis of breast tumor. Conversely, patients with endometrial carcinoma may present a second mammary neoplasm and the relative risk is around 2.0 (1, 17). Although the existence of a correlation between these two primary malignant neoplasms is clearly observed, the absence of systematic studies directed to the screening of endometrial cancer in women with breast carcinoma is surprising. This study deals with histological analysis of the endometrium of postmenopausal patients with breast cancer and aims to determine the possible changes that might have occurred in the onset of the disease.

    2008-01-01

    Background and Objective: Survivin is a novel member of the inhibitor of apoptosis (IAP) gene family. It is associated with more aggressive behavior and parameters of poor prognosis in most human cancers including gastric, colorectal and bladder carcinomas. However, conflicting data exist on its prognostic effect in breast cancer. This current study is designed to assess survivin expression in breast carcinoma relating results with clinico pathological parameters, proliferation (MIB-1) and molecular classification. Material and Methods: Our retrospective study com- prised of 65 archived cases of breast carcinoma. Samples from the tumor and the adjacent normal breast tissue were immuno stained for survivin and MIB-1. Nuclear and cytoplasmic survivin expression was evaluated in normal breast tissue and carcinoma regarding both the intensity and the percentage of positive cells. ER, PR, HER2 were used as surrogate markers to classify the cases into four molecular subtypes. Results: Survivin expression was detected in 78.5% of breast carcinomas. The adjacent normal breast tissue was immuno negative. Survivin expression showed significant association with increased tumor size ( p <0.0001), high histologic grade ( p =0.04), lymph node metastases ( p <0.001), advanced tumor stage ( p <0.0001), MIB-1 expression ( p =0.02), negative estrogen receptor status ( p =0.01) and negative progesterone receptor status ( p <0.0001). The subcellular localization of survivin significantly related to histologic grade, stage and lymph node involvement. The percentage of TNP (triple negative phenotype) and HER2+/ER-PR- tumors expressing survivin were significantly higher compared to the Luminal subtypes ( p =0.01). Conclusion: Survivin expression was associated with parameters of poor prognosis in breast cancer. Moreover, the cancer-specific expression of survivin, coupled with its importance in inhibiting cell death and in regulating cell division, makes it a potential target for novel

    Full Text Available Breast carcinomas are complex, three-dimensional tissues composed of cancer epithelial cells and stromal components, including fibroblasts and extracellular matrix. In vitro models that more faithfully recapitulate this dimensionality and stromal microenvironment should more accurately elucidate the processes driving carcinogenesis, tumor progression, and therapeutic response. Herein, novel in vitro breast carcinoma surrogates, distinguished by a relevant dimensionality and stromal microenvironment, are described and characterized. A perfusion bioreactor system was used to deliver medium to surrogates containing engineered microchannels and the effects of perfusion, medium composition, and the method of cell incorporation and density of initial cell seeding on the growth and morphology of surrogates were assessed. Perfused surrogates demonstrated significantly greater cell density and proliferation and were more histologically recapitulative of human breast carcinoma than surrogates maintained without perfusion. Although other parameters of the surrogate system, such as medium composition and cell seeding density, affected cell growth, perfusion was the most influential parameter.

    Full Text Available FLI1 is a member of ETS family of transcription factors that regulate a variety of normal biologic activities including cell proliferation, differentiation, and apoptosis. The expression of FLI1 and its correlation with well-known breast cancer prognostic markers (ER, PR and HER2 was determined in primary breast tumors as well as four breast cancer lines including: MCF-7, T47D, MDA-MB-231 and MDA-MB-468 using RT-qPCR with either 18S rRNA or ACTB (β-actin for normalization of data. FLI1 mRNA level was decreased in the breast cancer cell lines under study compared to the normal breast tissue; however, Jurkat cells, which were used as a positive control, showed overexpression compared to the normal breast. Regarding primary breast carcinomas, FLI1 is significantly under expressed in all of the stages of breast cancer upon using 18S as an internal control. This FLI1 expression was correlated with ER, PR and HER2 status. In conclusion FLI1 can be exploited as a preliminary marker that can predict the status of ER, PR and HER2 in primary breast tumors.

    Apocrine carcinoma of the breast is a rare, primary breast cancer characterized by the apocrine morphology, estrogen receptor-negative and androgen receptor-positive profile with a frequent overexpression of Her-2/neu protein (~30%). Apart from the Her-2/neu target, advanced and/or metastatic apocrine carcinomas have limited treatment options. In this review, we briefly describe and discuss the molecular features and new theranostic biomarkers for this rare mammary malignancy. The importance of comprehensive profiling is highlighted due to synergistic and potentially antagonistic molecular events in the individual patients.

    Adenoid cystic carcinoma (ACC) of the breast is a rare malignant salivary-type neoplasm that has a good prognosis and represents less than 1% of all breast cancers. It is a triple negative carcinoma that presents as a painful mass. The mean age at the time of diagnosis is 50-60 years old. The solid variant of this type of tumour with basaloid features and presence of nodal metastases is very rare and considered to have a more aggressive clinical course. We present a case with presence of axillary lymph node metastases that was successfully treated with no evidence of recurrence one year after the diagnosis and review the literature.

    Thyroid cancer incidence is rapidly increasing. Papillary Thyroid Carcinoma (PTC), the most frequent hystotype, usually displays good prognosis, but no effective therapeutic options are available for the fraction of progressive PTC patients. BRAF and RET/PTC are the most frequent driving genetic lesions identified in PTC. We developed two complementary in vitro models based on RET/PTC1 oncogene, starting from the hypothesis that miRNAs modulated by a driving PTC-oncogene are likely to have a role in thyroid neoplastic processes. Through this strategy, we identified a panel of deregulated miRNAs. Among these we focused on miR-199a-3p and showed its under-expression in PTC specimens and cell lines. We demonstrated that miR-199a-3p restoration in PTC cells reduces MET and mTOR protein levels, impairs migration and proliferation and, more interesting, induces lethality through an unusual form of cell death similar to methuosis, caused by macropinocytosis dysregulation. Silencing MET or mTOR, both involved in survival pathways, does not recapitulate miR-199a-3p-induced cell lethality, thus suggesting that the cooperative regulation of multiple gene targets is necessary. Integrated analysis of miR-199a-3p targets unveils interesting networks including HGF and macropinocytosis pathways. Overall our results indicate miR-199a-3p as a tumor suppressor miRNA in PTC.

    Invasive lobular breast cancer (ILC) accounts for 10-15% of all invasive breast carcinomas. It is generally ER positive (ER+) and often associated with lobular carcinoma in situ (LCIS).

    P-31 magnetic resonance (MR) spectroscopy has been used to characterize breast lesions and to monitor tumor response to chemotherapy in patients with breast carcinoma and non-Hodgkin lymphoma. PME/PCr was the most useful ratio in differentiating carcinomatous from benign breast masses. Both breast carcinoma and lymphoma patients showed elevated levels of PMEs, Pi, and PDEs. P-31 ratio trends were observed in all patients following chemotherapy. These reached a point of maximum change, after which they reversed. The same trends were observed following each administration. Changes in P-31 ratios and in tumor pH were detected within 1 hour following chemotherapy. The rate of change of certain ratios (eg, Pi/adenosine triphosphate) appears to be a good early indicator of tumor response

    Breast-conserving surgery has become an important way of surgical treatment for breast cancer worldwide nowadays. Multiphoton microscopy (MPM) has the ability to noninvasively visualize tissue architectures at the cellular level using intrinsic fluorescent molecules in biological tissues without the need for fluorescent dye. In this study, MPM is used to image the microstructures of terminal duct lobular unit (TDLU), invasive ductal carcinoma and the boundary region between normal and cancerous breast tissues. Our study demonstrates that MPM has the ability to not only reveal the morphological changes of the cuboidal epithelium, basement membrane and interlobular stroma but also identify the boundary between normal breast tissue and invasive ductal carcinoma, which correspond well to the Hematoxylin and Eosin (H and E) images. Predictably, MPM can monitor surgical margins in real time and provide considerable accuracy for resection of breast cancerous tissues intraoperatively. With the development of miniature, real-time MPM imaging technology, MPM should have great application prospects during breast-conserving surgery.

    Breast cancer among women is one of the most common carcinomas worldwide. Compared to developed countries, the breast cancer cases reported in India have boosted rapidly. At the same time, alarming statistics show that ratio of mortality cases over the total incidences is significantly high in comparison to developed world (Global Heath Estimates, WHO 2015). In recent times, several oncogenic signaling pathways have shown convergent effects on various types of cancer cell metabolism including breast cancer leading to tumor development. In 1931, German biochemist Otto Warburg revealed that cancer cells burn sugar (glycolysis) differently than normal cells. Cancer cells prefer to burn sugar over energy rich fats even when cellular oxygen conditions favor mitochondrial fat burning. Further, Warburg hypothesized that cancer is caused by mitochondrial dysfunction forcing the cells to use aerobic glycolysis instead of oxidative phosphorylation (OXPHOS). MicroRNAs (miRNAs) are critical classes of small ~22 nt non-coding endogenous RNAs implicated in gene expression regulation. To date, miRNAs have shown to regulate many cellular metabolic pathways critical for breast carcinoma patho-physiology. There is common consent that miRNAs dedicated to mitochondria and cellular metabolism have profound positive effects on breast carcinoma survival and metastasis. Therefore, in future there is huge scope for identification of miRNA types playing as a driver in mitochondria for breast tumor development. Further, several strategies to taming as well as knocking down these miRNA in breast tumor would be one of the fascinating approaches in medical sciences and cancer therapy. Here, we review updated scientific findings and possible therapeutic interventions with reference to miRNAs, mitochondria, cellular metabolism and breast carcinoma.

    Generalized morphea is a rare idiopathic form of scleroderma that literally means “hard skin.” Morphea is usually considered an isolated event that is not associated with malignancy. However, case reports of lung, hematologic, and breast cancer occurring simultaneously with large plaque morphea have caused dermatologists to question whether a work-up for malignancy is appropriate. We highlight a case of generalized morphea that preceded invasive ductal carcinoma of the breast and provide a di...

    In case of concerning about recurrence case after operative treatment of breast cancer, we must suppose existence of dormant breast cancer cell. To elucidate a rational treatment of the breast cancer in the dormant stage, we have developed a new treatment model using human breast carcinoma xenografts (MCF-7, R-27 and Br-10) in nude mice. After the sc inoculation of the tumors, the treatment was initiated with or without the previous estradiol (E2) stimulation. While MCF-7 was sensitive to mitomycin C (6 mg/kg i.p.) and and tamoxifen pellet (2.5 mg/mouse s.c.) in the dormant and exponential growth phase, R-27 and Br-10 were sensitive to the drugs only in the exponential growth phase but not in the dormant stage. These results suggested that the sensitivity of human breast carcinoma cells in the dormant stage is rather low, however some strain would be also sensitive to the treatment. This model seems to be useful in evaluating the adjuvant therapy of breast carcinoma after surgery.

    Pleomorphic lobular carcinoma is an uncommon form of breast cancer and a subtype of invasive lobular carcinoma. It has unique histopathologic features that translate to a more aggressive phenotype with an associated poor prognosis. Unlike classical invasive lobular carcinoma, it can lose estrogen and progesterone receptor expression and demonstrate HER-2/neu amplification. It remains to be determined, however, whether the pleomorphic histology independently predicts a worse outcome or whether other known associated negative prognostic factors such as larger tumor size, increased metastatic disease, and associated worse molecular subtypes commonly present in pleomorphic carcinoma account for the poor prognosis. Here we present an updated review of the unique pathologic and clinical features of pleomorphic lobular carcinoma needed to guide management for women with this subtype of cancer.

    : To study the pattern of expression of triiodothyronine (T3) receptors and type I 5'-deiodinase in various breast pathologies comparing malignant and nonmalignant epithelia that include lactational change. A retrospective study was performed on formalin-fixed, paraffin-embedded archival material from 146 cases of carcinomas, normal breast tissue, breast tissue showing lactational change, and benign breast lesions. Archive tissue blocks were selected and sections were cut for immunohistochemistry to study the expression of thyroid hormone receptor α-1 (THR-α1) in the cytoplasm and nuclei of cells in tissues under study. Thick sections were cut for type I 5'-deiodinase evaluation using reverse transcriptional PCR.THR-α1 showed no nuclear expression in the carcinoma group. Combined nuclear and cytoplasmic expression was seen in 47.6%, 63.4%, 64.3%, and 58.3% in the benign, fibrocystic, fibroadenoma, and lactational change groups, respectively, compared with only 17.4% of cases in the carcinoma group. This suggests deregulation of the thyroid hormone in breast cancer. Theories for the possible role of thyroid hormone in the pathogenesis of breast cancer are discussed.Type I 5'-deiodinase was not shown to be differentially expressed in malignant versus nonmalignant groups. Our study revealed substantial reduction in the protein expression profile of THRs in malignant versus nonmalignant mammary epithelium suggesting a possible role in breast cancer development. The presence of THRs in mammary epithelium seems to be protective against the development of breast cancer. This could serve as a potential prognostic and therapeutic target for breast cancer.

    We examined the expression and ligand specificity of the alpha 2 beta 1 integrin on human mammary epithelial cells (HMEC) and a panel of breast carcinoma cell lines in vitro. We found that the alpha 2 beta 1 integrin was universally, but quite variably expressed on these cells by FACS analysis. No significant correlation was observed between its expression and other known cellular phenotypes. Substrate attachment assays using blocking antibodies demonstrated that alpha 2 beta 1 integrin served as a receptor for collagen on HMEC and almost all breast carcinoma cells. However, its contribution to laminin binding of these cells appeared to be related to cellular differentiation as evaluated by sex steroid receptor status and by markers of epithelial-mesenchymal transition, i.e. loss of E-cadherin and expression of vimentin. Two different populations of non-malignant immortalized HMEC (184A1N4 and MCF-10A) contained cells capable of using alpha 2 beta 1 integrin as a laminin receptor. Breast cancer cell lines positive for estrogen receptor (ER) and E-cadherin (MCF-7, T47D, ZR75-1) could also use alpha 2 beta 1 integrin as a laminin receptor. Conversely, alpha 2 beta 1 integrin appeared to be incapable of binding to laminin or to be a very minor receptor for laminin on metastatic ER-negative breast carcinoma cells that expressed vimentin (MDA-MB 231, MDA-MB 435, and MDA-MB 436). These findings suggest that the ligand specificity of alpha 2 beta 1 integrin, i.e. its function as a laminin receptor, may be regulated during the malignant progression of breast carcinoma cells. A reduced contribution of alpha 2 beta 1 integrin to the cellular laminin binding appears to be associated with an increased malignant phenotype and with an epithelial-mesenchymal transition of breast carcinoma cells.

    Full Text Available Abstract Breast carcinoma with osteoclastic giant cells (OGCs is characterized by multinucleated OGCs, and usually displays inflammatory hypervascular stroma. OGCs may derive from tumor-associated macrophages, but their nature remains controversial. We report two cases, in which OGCs appear in common microenvironment despite different tumoural histology. A 44-year-old woman (Case 1 had OGCs accompanying invasive ductal carcinoma, and an 83-year-old woman (Case 2 with carcinosarcoma. Immunohistochemically, in both cases, tumoural and non-tumoural cells strongly expressed VEGF and MMP12, which promote macrophage migration and angiogenesis. The Chalkley count on CD-31-stained sections revealed elevated angiogenesis in both cases. The OGCs expressed bone-osteoclast markers (MMP9, TRAP, cathepsin K and a histiocyte marker (CD68, but not an MHC class II antigen, HLA-DR. The results indicate a pathogenesis: regardless of tumoural histology, OGCs derive from macrophages, likely in response to hypervascular microenvironments with secretion of common cytokines. The OGCs have acquired bone-osteoclast-like characteristics, but lost antigen presentation abilities as an anti-cancer defense. Appearance of OGCs may not be anti-tumoural immunological reactions, but rather pro-tumoural differentiation of macrophage responding to hypervascular microenvironments induced by breast cancer.

    Full Text Available Abstract Background High serum levels of estradiol are associated with increased risk of postmenopausal breast cancer. Little is known about the gene expression in normal breast tissue in relation to levels of circulating serum estradiol. Methods We compared whole genome expression data of breast tissue samples with serum hormone levels using data from 79 healthy women and 64 breast cancer patients. Significance analysis of microarrays (SAM was used to identify differentially expressed genes and multivariate linear regression was used to identify independent associations. Results Six genes (SCGB3A1, RSPO1, TLN2, SLITRK4, DCLK1, PTGS1 were found differentially expressed according to serum estradiol levels (FDR = 0. Three of these independently predicted estradiol levels in a multivariate model, as SCGB3A1 (HIN1 and TLN2 were up-regulated and PTGS1 (COX1 was down-regulated in breast samples from women with high serum estradiol. Serum estradiol, but none of the differentially expressed genes were significantly associated with mammographic density, another strong breast cancer risk factor. In breast carcinomas, expression of GREB1 and AREG was associated with serum estradiol in all cancers and in the subgroup of estrogen receptor positive cases. Conclusions We have identified genes associated with serum estradiol levels in normal breast tissue and in breast carcinomas. SCGB3A1 is a suggested tumor suppressor gene that inhibits cell growth and invasion and is methylated and down-regulated in many epithelial cancers. Our findings indicate this gene as an important inhibitor of breast cell proliferation in healthy women with high estradiol levels. In the breast, this gene is expressed in luminal cells only and is methylated in non-BRCA-related breast cancers. The possibility of a carcinogenic contribution of silencing of this gene for luminal, but not basal-like cancers should be further explored. PTGS1 induces prostaglandin E2 (PGE2 production which

    Population-based screening for carcinoma of the breast by mammography has yielded an abundance of data, not all of which have been processed yet, the mammographic (radiographic) data in particular. The present study concerns an analysis of the mammographic signs in the histologically proven carcinomas (invasive and intraductal) detected by these three screening programs. The radiographic signs of the screened carcinomas were compared with those of the clinical carcinomas diagnosed in the Utrecht University Hospital (to be called AZU carcinomas). These AZU carcinomas were taken as reference material, and were therefore analysed in the same way as the screening material. (Auth.)

    The lung large-cell neuroendocrine carcinoma (LCNEC) is a very rare aggressive neuroendocrine tumor with a high propensity to metastasize and very poor prognosis. We report an atypical presentation of lung LCNEC was diagnosed from a metastatic nodule on the breast. Our patient is a 59-years-old woman that presented in March 2014 nonproductive cough. A CT scan showed multiple brain, lung, adrenal gland and liver secondary lesions; moreover, it revealed a breast right nodule near the chest measuring 1.8 cm. The breast nodule and lung lesions were biopsied and their histology and molecular diagnosis were LCNEC of the lung. To our knowledge, this is the first documented case of breast metastasis from LCNEC of the lung. Furthermore, breast metastasis from extramammary malignancy is uncommon and its diagnosis is difficult but important for proper management and prediction of prognosis. Therefore, a careful clinical history with a thorough clinical examination is needed to make the correct diagnosis. Moreover, metastasis to the breast should be considered in any patient with a known primary malignant tumor history who presents with a breast lump. Anyhow, pathological examination should be performed to differentiate the primary breast cancer from metastatic tumor. Therefore, an accurate diagnosis of breast metastases may not only avoid unnecessary breast resection, more importantly it is crucial to determine an appropriate and systemic treatment. © 2015 John Wiley & Sons Ltd.

    The concept of early detection of breast cancer is first correlated to primary tumor size and than the efforts relating to 'early detection' are described: identification of in-sity carcinomas and other histologic lesions which might be either precancerous or early preinvasive forms of breast cancer; definition of a high risk group, using here mammography. The examination of contralateral breast is emphasized as part of the definition of 'high risk', as well as, most recently, the possibility of screnning of assymptomatic populations. Partial mastectomy, or lumpectomy, are briefly analysed in the therapeutic behavior. (M.A.) [pt

    Secondary radiation-induced cancers are rare but well-documented as long-term side effects of radiation in large populations of breast cancer survivors. Multiple neoplasms are rare. We report a case of esophageal adenocarcinoma in a patient treated previously for breast cancer and clear cell carcinoma of the kidney. A 56 year-old non smoking woman, with no alcohol intake and no familial history of cancer; followed in the National Institute of Oncology of Rabat Morocco since 1999 for breast carcinoma, presented on consultation on January 2011 with dysphagia. Breast cancer was treated with modified radical mastectomy, 6 courses of chemotherapy based on CMF regimen and radiotherapy to breast, inner mammary chain and to pelvis as castration. Less than a year later, a renal right mass was discovered incidentally. Enlarged nephrectomy realized and showed renal cell carcinoma. A local and metastatic breast cancer recurrence occurred in 2007. Patient had 2 lines of chemotherapy and 2 lines of hormonotherapy with Letrozole and Tamoxifen assuring a stable disease. On January 2011, the patient presented dysphagia. Oesogastric endoscopy showed middle esophagus stenosing mass. Biopsy revealed adenocarcinoma. No evidence of metastasis was noticed on computed tomography and breast disease was controlled. Palliative brachytherapy to esophagus was delivered. Patient presented dysphagia due to progressive disease 4 months later. Jejunostomy was proposed but the patient refused any treatment. She died on July 2011. We present here a multiple neoplasm in a patient with no known family history of cancers. Esophageal carcinoma is most likely induced by radiation. However the presence of a third malignancy suggests the presence of genetic disorders.

    Full Text Available Background: Tumor budding is a histopathologic entity refers to small cluster of cancer cells at the invasive edge of tumor. It was assumed that tumor budding is linked to epithelial-mesenchymal transition, an early event in metastasis. Objective: This study aimed to find out the correlation of tumor budding with E-cadherin and MMP-9 expression and risk of metastasis in breast carcinoma. Method: We investigated 35 cases breast carcinoma with metastasis and 35 cases without metastasis. The number of tumor budding was counted in cytokeratin-stained slides with 400x magnification (0.57 mm2. Result: Cut-off point by ROC analysis was 11 and the patient was categorized into low grade (0-10 buds and high grade (11 or more buds tumor budding. Inter-observer agreement was good with K value 0.914. Low level of E-cadherin was not significantly correlated with high grade tumor budding (p=0.660, meanwhile high level of MMP-9 was significantly correlated with high grade tumor budding (p=0.001. High grade tumor budding was a significant, independent risk factor of metastasis in breast carcinoma (OR=38.2, 95% CI 7.5-193.7, p<0.001. Conclusion: In conclusion, tumor budding grade is related to level of MMP-9 but has no correlation E-cadherin expression. High grade tumor budding is an independent risk factor of metastasis in breast carcinoma.

    Fibroadenomas are a type of benign tumor that occur in young women below the age of 35 years old. The tumors are the second most common type of tumor after fibrocystic disease. The chance of carcinoma arising in a fibroadenoma is extremely low. To date, fibroadenomas can evolve into a number of different types of malignancy. The present study is the first to describe a case of bilateral primary breast cancer with a unilateral invasive ductal carcinoma within a fibroadenoma. The current study presents a case of a 48-year-old female who presented with 2 stiff lumps on bilateral breasts, diagnosed as bilateral breast carcinoma, with a unilateral invasive ductal carcinoma within a fibroadenoma in the right breast. The patient underwent a bilateral mastectomy and subsequently received 4 cycles of chemotherapy (epirubicin, 60 mg/m2 and cyclophosphamide, 600 mg/m2) every 21 days, followed by 4 cycles of docetaxel chemotherapy (100 mg/m2) every 21 days. The patient then received maintenance endocrine therapy (tamoxifen, 20 mg, twice daily) for 19 months. The patient was followed up every 3 months, and at the last follow-up examination in May 2015, the patient exhibited no signs of recurrence. PMID:26622700

    The treatment of ductal carcinoma in situ has been widely reported in the western and other Asian countries, but the relevant data in Hong Kong are relatively limited. This study aimed to evaluate the latest detection and treatment pattern for ductal carcinoma in situ in Hong Kong so as to guide planning of future service provision. This was a retrospective case series study. A total of 573 patients who registered with the Hong Kong Breast Cancer Registry, and were diagnosed and treated in Hong Kong from January 2001 to December 2011 were reviewed. Compared with invasive breast cancer patients, patients with ductal carcinoma in situ were younger (median, 48.6 vs 50.3 years; Pincome (PHong Kong, ductal carcinoma in situ is more frequently found in the higher social classes and managed in the private sector. The clinical outcome of ductal carcinoma in situ is excellent and more than half of the patients can be successfully managed with breast-conserving surgery.

    Invasive pleomorphic lobular carcinoma (PLC) is an aggressive subtype of invasive lobular carcinoma of the breast, which has its own histopathological and biological features. The metastatic patterns for PLC are distinct from those of invasive ductal carcinoma. In addition, pancreatic metastasis from PLC is extremely rare. We report a rare case of a 48-year-old woman presenting with clinical gastrointestinal symptoms and pancreatic metastasis of PLC. The pancreatic tumor was composed of pleomorphic tumor cells arranged in the form of solid sheets and nests and as single files, with frequent mitotic figures, nucleolar prominence, high nuclear to cytoplasmic ratio and loss of cohesion. The malignant cells were positive for p120 (cytoplasmic) and GATA3 and negative for estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2, E-cadherin, gross cystic disease fluid protein 15 and mammaglobin, which indicated a lobular carcinoma phenotype of the breast. To the best of our knowledge, this is one of the few reported cases in the literature of pancreatic metastasis of invasive lobular carcinoma of the breast, of which the definitive diagnosis was obtained only after surgery. Rare metastasis sites should be considered, particularly, when a patient has a medical history of PLC.

    Immune competence was evaluated in 43 patients of carcinoma breast, 77 patients of cancer cervix, as compared to 30 normal healthy women. The study also included 25 women from the two carcinoma groups, who had undergone radiotherapy. A reduction in the white blood cell count, absolute lymphocyte count, active T-cell count and absolute T-cell count were observed in patients with carcinoma of the breast and cervix prior to irradiation. Radiation therapy resulted in a striking reduction of all the three parameters in both the carcinoma groups. Substantial recovery was observed within a year after cessation of therapy. Increased number of peripheral B lymphocytes was observed in carcinoma of the breast as well as the cervix prior to irradiation. At completion of radiation, the number decreased markedly in both groups of patients. Gradual recovery took place within a year. The reduction in lymphocyte numbers and its subpopulations could not be attributed to thymic irradiation, since patients receiving pelvic and mediastinal (including thymic) radiotherapy showed similar changes.

    Full Text Available Worldwide, breast cancer is the most frequently diagnosed life-threatening cancer and the leading cause of cancer death among women. Approximately 7% of all breast cancers are diagnosed in women <40 years of age. Young age at diagnosis influences prognosis negatively as they present with more advanced disease at diagnosis and a poorer 5-year survival than older patients. The present study includes breast cancer patients in the age group of 18 to 40 years to enrich our knowledge about clinical presentation and pathological characteristics of breast cancer. To find out the clinical presentation and pathological characteristics of breast cancer among the young age group.  This cross-sectional study was done over 100 cases of histopathologically proven breast cancer from structured Questionnaire was used as data collection tool. Mean age was 33.89 years. Among the respondents 88% are married. Among the total studied population 61 respondents had the history of oral contraceptive pill use. Family history of cancer presents in 13.0% respondents and absent in 87.0% respondents. Among the respondents 95% patients presented with lump in the breast. 97.0% had invasive carcinoma 90% were invasive ductal carcinoma in which 46.0% were moderately differentiated. 51.0% patients were in the stage IIa and stage IIb.

    Objective: To evaluate and recognize the dynamic and morphological MRI characteristics of ductal carcinoma in situ (DCIS) of the breast and provide imaging information for the early detection and treatment planning. Methods: All MRI data in 71 patients with histologically proved DCIS were analyzed retrospectively. The 71 patients were divided into two groups, N1 (pure DCIS, 44 patients) and N2 (DCIS with microinvasion, 27 patients). According to the BI-RADS descriptors, all lesions were defined as a focus (smaller than 5 mm in diameter), mass and no-mass-like three enhancement types. The morphological features (M1 = focus, M2 =linear or linear-branched, M3 = branching-ductal, M4 = segmental, M5 = focal, M6 = regional, M7 = diffuse, M8 = mass) and the time-intensity curve (TIC) pattern [type Ⅰ (persistent enhancement curves), type Ⅱ (plateau), type Ⅲ (washout) and type Ⅳ (the same enhancement as glandular tissue)] were described. Chi-square test was used for the morphological characteristics of lesions. Results: The 73 DCIS lesions were found in 71 patients, and 5.5% (n=4) were stippled lesions, 87.7% (n=64) were no-mass like lesions, 6.8% (n=5) were mass-like lesions. In no-mass-like lesions (n= 64), M3 was found in 15 cases, M4 in 34 cases, M5 in 9 cases and M6 in 6 cases, respectively, M3 and M4 were the most common distribution patterns. In N1 group (n=45) and N2 group (n=28), M3, M4, M5, M6 were found in 7 and 8, 21 and 13, 7 and 2, 3 and 3 cases, respectively. There were no statistic differences between two groups (P>0.05). In 31 showed heterogeneous enhancement, both M3 and M4 were observed in 35.5% (11/31). In 26 clustered ring enhancement lesions, M4 was observed in 88.5% (23/26). Four lesions showed reticular enhancement, 2 lesions showed a clumped enhancement and 1 lesion showed homogeneous enhancement. In 5 mass-like lesions, N1 group had 3 cases, N2 group had 2 cases. Four lesions showed lobulated margin, 4 lesions showed speculated margin, 1

    Adenoid cystic carcinoma (ACC) is a subtype of adenocarcinoma that is usually seen in the salivary glands. It has also been reported in other organs including the breast, skin, tracheobronchial tree, cervix, larynx, and Bartholin gland. ACC in the breast is rare, accounting for less than 0.1% of all breast cancers. Furthermore, the imaging characteristics of ACC of the breast have not been well described in the literature, especially regarding the findings with magnetic resonance imaging (MRI). Here, we report radiologic findings of a rare case of ACC in the breast by mammography, sonography, computed tomography (CT), positron emission tomography/CT, and MRI with pathologic correlation and a review of the literature

    The role of the integrin alpha 6 beta 1 in breast carcinoma progression was studied by targeted elimination of this integrin in MDA-MB-435 cells, a human breast carcinoma cell line that is highly metastatic in athymic mice. The strategy used is based on the finding that expression of a cytoplasmi...... in the liver after intrahepatic injection because of extensive apoptosis in the beta 4-delta CYT transfectants. These data suggest that a major function of the alpha 6 beta 1 integrin in breast carcinoma is to facilitate tumorigenesis and promote tumor cell survival in distant organs....

    Full Text Available Metastatic lesions to the clivus have been reported in various cancers including lung cancer, prostate carcinoma, skin melanoma, and hepatocellular carcinoma. There have been only a few reports of breast cancer presenting with isolated clival metastasis. We report a case of 35-year-old lady, who was known case of breast carcinoma presented with diplopia as the only sign of clival metastasis. The etiology was established by magnetic resonance imaging which showed an enhancing lesion in the clivus. The diagnosis of clival metastasis from breast cancer was confirmed by transsphenoidal biopsy.

    The objective of this study was to compare the differential expression of established histopathologic and biologic markers of proliferation, apoptosis, and angiogenesis in invasive lobular carcinoma (ILC) and invasive ductal carcinoma (IDC) in a group of axillary node-negative breast cancers. Two hundred twenty patients with axillary node-negative ILC and IDC who underwent surgery at the University of Texas M. D. Anderson Cancer Center between 1978 and 1995 had tissue available for analysis. Of these, 206 (94%) had IDC and 14 (6%) had ILC. Estrogen receptors, progesterone receptors, tumor and stromal expression of vascular endothelial growth factor receptor 2, CD44, laminin-5, E-cadherin, and topoisomerase-2 were evaluated by immunohistochemical analysis. HER2/neu and alpha6beta4 integrin were evaluated by in situ hybridization. The Fisher exact test was used to calculate significant differences between ILC and IDC. Median age was 59 years. Invasive lobular carcinoma was more likely to occur in patients aged > 50 years. Invasive lobular carcinoma tended to be > 2 cm (50% vs. 39%), have a nuclear grade of 1/2 (100% vs. 72%), be estrogen receptor positive (93% vs. 70%), HER2/neu negative (92% vs. 68%), have high CD44 expression (31% vs. 16%), low stromal vascular endothelial growth factor receptor 2 expression (36% vs. 47%), no E-cadherin expression (0 vs. 90%), and low laminin-5 expression (15% vs. 25%), compared with IDC. Invasive lobular carcinoma and IDC might be distinct histologic types of breast cancer with different expression of biologic markers. These differences, not all being statistically significant in this small study, might generate hypotheses to develop tailored options for future systemic therapy.

  4. Myiasis associated with an invasive ductal carcinoma of the left breast: case study

    Felipe Tavares Rodrigues

    Full Text Available ABSTRACT Most breast cancers originate in the ductal epithelium and are referred to as invasive ductal carcinoma. In this study we report on the clinical procedures adopted to diagnose myiasis in association with infiltrating metastatic breast carcinoma in a female patient. A 41 years old woman came to the Federal Hospital of Andaraí complaining of intense itching, warmth, redness and hardening of the breast, which had acquired the aspect of an orange peel. A lesion in the left breast was cavitated, dimpled, had fetid odor, and had fibrotic and infected air nodules filled with exudate and Dipteran larvae. The tissue was cleaned and 33 larvae were extracted. The patient was hospitalized and received Ivermectin. Eighteen of the larvae extracted from the patient were placed in 70% alcohol, and twelve were placed in a container with sterile wood shavings under controlled conditions until they metamorphosed into adults. The taxonomic identification of the flies revealed that the culprit was Cochliomyia hominivorax. A histopathological exam conducted three months earlier had revealed infiltrating ductal carcinoma. Two months after the myiasis treatment, the breast tissue had healed. The patient had waited ten days from the onset of the myiasis to seek treatment, and that delay interfered negatively in the prognosis of both the neoplasm and the myiasis. This study is relevant to public health in view of the strong social impact of myiasis.

    Between 1960 and 1978, 87 patients with locally advanced Tsub(3-4)Nsub(0-3)M 0 carcinoma of the breast were treated with 5,000 to 8,000 rad of external beam supervoltage radiotherapy. Initial clinical eradication of the tumour was observed in 76 of 87 cases (87%), but the actuarial probability of local control at 5 yr was only 53%. Furthermore, the actuarial probability of disease-free survival was 25% at 5 yr and 13% at 10 yr. Most of the patients eventually succumbed to metastatic breast carcinoma and the actuarial survival at 5 yr was 43% and at 10 yr, 16%. The addition of adjuvant low-dose chemotherapy, given to 13 patients, did not affect the rates of local control, survival or disease-free survival. The most common long-term complication was extensive and deforming radiation-induced fibrosis of the treated breast. The actuarial probability of 10-yr survival without a local recurrence and without severe fibrosis of the treated breast was only 17.5%. The role of adjuvant high-dose chemotherapy in the treatment of locally advanced breast carcinoma and the possible use of improved radiotherapy techniques to achieve a more effective long-term local control and a more desirable cosmetic end result are discussed.

    Invasive lobular breast cancer (ILC) accounts for 10-15% of all invasive breast carcinomas. It is generally ER positive (ER+) and often associated with lobular carcinoma in situ (LCIS). Genome-wide association studies have identified more than 70 common polymorphisms that predispose to breast cancer, but these studies included predominantly ductal (IDC) carcinomas. To identify novel common polymorphisms that predispose to ILC and LCIS, we pooled data from 6,023 cases (5,622 ILC, 401 pure LCIS) and 34,271 controls from 36 studies genotyped using the iCOGS chip. Six novel SNPs most strongly associated with ILC/LCIS in the pooled analysis were genotyped in a further 516 lobular cases (482 ILC, 36 LCIS) and 1,467 controls. These analyses identified a lobular-specific SNP at 7q34 (rs11977670, OR (95%CI) for ILC = 1.13 (1.09-1.18), P = 6.0 × 10(-10); P-het for ILC vs IDC ER+ tumors = 1.8 × 10(-4)). Of the 75 known breast cancer polymorphisms that were genotyped, 56 were associated with ILC and 15 with LCIS at Plobular breast cancer specific predisposition polymorphism at 7q34, and shown for the first time that common breast cancer polymorphisms predispose to LCIS. We have shown that many of the ER+ breast cancer predisposition loci also predispose to ILC, although there is some heterogeneity between ER+ lobular and ER+ IDC tumors. These data provide evidence for overlapping, but distinct etiological pathways within ER+ breast cancer between morphological subtypes.

    Full Text Available Abstract Background To date, the clinical presentation and prognosis of mixed ductal/lobular mammary carcinomas has not been well studied, and little is known about the outcome of this entity. Thus, best management practices remain undetermined due to a dearth of knowledge on this topic. Methods In this paper, we present a clinicopathologic analysis of patients at our institution with this entity and compare them to age-matched controls with purely invasive ductal carcinoma (IDC and historical data from patients with purely lobular carcinoma and also stain-available tumor specimens for E-cadherin. We have obtained 100 cases of ductal and 50 cases of mixed ductal/lobular breast carcinoma. Results Clinically, the behavior of mixed ductal/lobular tumors seemed to demonstrate some important differences from their ductal counterparts, particularly a lower rate of metastatic spread but with a much higher rate of second primary breast cancers. Conclusions Our data suggests that mixed ductal/lobular carcinomas are a distinct clinicopathologic entity incorporating some features of both lobular and ductal carcinomas and representing a pleomorphic variant of IDC.

  9. Primary small cell neuroendocrine carcinoma of the breast: The histogenetic diatribe

    Full Text Available The article entitled “Primary small cell neuroendocrine carcinoma of the breast: a report of two cases and review of the literature” by Spinelli et al. [1]. The authors stated that “the histogenesis is still unclear because the presence of neuroendocrine cells in normal breast has not been proved conclusively”. Moreover they reported two histogenetic hypotheses, the first one stating that “small cell neuroendocrine carcinoma (SCNC is a variant of metaplastic carcinoma arising from a lobular or ductal carcinoma”, the second one claiming that “it is a distinct type of breast carcinoma different from the usual type”. We appreciate this case report and we agree with the authors on the histogenetic diatribe of this rare type of breast neoplasia. In this background, we would highlight our previous case report about a solid variant of mammary adenoid cystic carcinoma merging with "small cell carcinoma" [2] in which we found positivity for CD10 and S100 and negativity for estrogen receptors, both in sbACC and in SCC, in keeping with a myoepithelial origin of both neoplastic areas [3] supporting the hypothesis that the “two components share the same histogenetic myoepithelial origin and represent an example of dedifferentiation along neuroendocrine phenotype lines occurring in a multipotential neoplastic stem line, already committed towards a myoepithelial phenotype”. These findings are in keeping with the first hypothesis about the metaplastic, divergent histogenetic nature of SNSC and we think that this rare SNSC, albeit arising from a different tumor, could be introduced in this case review of the literature, also for its contribute to the histogenetic diatribe.

In this study, we used short tandem repeated sequences to assess genomic heterogeneity and to determine hereditary relationships among primary tumor areas and regional metastases from 30 breast cancer patients. We found that primary carcinomas were genetically heterogeneous and sampling multiple areas was necessary to adequately assess genomic variability. LN metastases appeared to originate at different time periods during disease progression from different sites of the primary tumor and the extent of genomic divergence among regional metastases was associated with a less favorable patient outcome (P = 0.009). In conclusion, metastasis is a complex process influenced by primary tumor heterogeneity and variability in the timing of dissemination. Genomic variation in primary breast tumors and regional metastases may negatively impact clinical diagnostics and contribute to therapeutic resistance. PMID:26279627

    Large cell neuroendocrine carcinoma of the breast (NECB) is an extremely rare type of breast cancer; little is known about effective chemotherapies, and data on pathologic response to treatment are unavailable. We report the case of a 34-years-old woman with large cell NECB with initial clinical and pathologic evidence of treatment response to anthracycline-containing neo-adjuvant therapy. Histologic reassessment early during anthracycline chemotherapy revealed cell death with necrosis of 50% of the tumor cells seen in the biopsy specimen. After completing neo-adjuvant chemotherapy, the patient underwent breast-conserving surgery. Pathologic evaluation of the surgical specimen showed a partial response but margins were positive for residual carcinoma. Despite repeated neo-adjuvant chemotherapy, radiotherapy, and surgical resection, the tumor grew rapidly between surgeries and recurred systemically. Therefore, we review the literature on large cell NECB and its treatment options. © 2015 Wiley Periodicals, Inc.

    Full Text Available We report a very rare case of extensive ductal carcinoma in situ (DCIS of the breast with secretory features in a 30-year old Japanese woman. The patient presented with a nodule in the lower inner quadrant of the left breast measuring approximately 2-3 cm, accompanied by an irregular tumor shadow with segmental microcalcification on mammography. These findings suggested malignancy, and excisional biopsy was performed following core needle biopsy. Pathological diagnosis was that of DCIS with secretory features. A treatment plan of simple mastectomy and sentinel lymph node biopsy was chosen. Most previous reports have only described invasive secretory carcinoma of the breast. We have only been able to find 2 case reports of non-invasive secretory lesion in the English literature to date. Because the characteristics of this lesion are not widely known, we thought it important to share our findings.

    Tuberculous mastitis is an uncommon disease even in countries where tuberculosis is highly endemic. It typically presents a diagnostic challenge masquerading as carcinoma or other primary disease of the breast. We report the case of a young multiparous Nigerian woman who presented with a tender left breast lump and enlargement of the left axillary lymph nodes for which a provisional diagnosis of carcinoma of the breast was made after clinical and radiological evaluation. The mass was pathologically diagnosed as tuberculous mastitis and anti-tuberculous therapy was instituted although she later absconded. This case shows that TM may present a diagnostic challenge on clinical, radiologic and microbiological investigation. Therefore, a high index of suspicion as well as FNAC and/or histological evaluation of tissue samples remain very important its diagnosis.

    We have reported that fusions of murine dendritic cells (DCs) and murine carcinoma cells reverse unresponsiveness to tumor-associated antigens and induce the rejection of established metastases. In the present study, fusions were generated with primary human breast carcinoma cells and autologous DCs. Fusion cells coexpressed tumor-associated antigens and DC-derived costimulatory molecules. The fusion cells also retained the functional potency of DCs and stimulated autologous T cell proliferation. Significantly, the results show that autologous T cells are primed by the fusion cells to induce MHC class I-dependent lysis of autologous breast tumor cells. These findings demonstrate that fusions of human breast cancer cells and DCs activate T cell responses against autologous tumors.

    We present a case of apocrine breast carcinoma in a 45 year-old woman with bilateral silicone breast prosthesis whose clinical manifestations and mammography were that of a palpable nodule-high glandular density, rounded and with imprecise borders devoid of any visible microcalcifications. A bibliographical revision confirmed the infrequent association of this type of tumor with the presence of silicone breast implants, precisely in which we consider its radiological interest to lie.

    Technetium-99-Sestamibi scintimammography has emerged as a new procedure for the imaging of breast tumors, Currently, a large clinical experience has been developed and the results published. At the present time, the major drawback of this procedure appears to be its low sensitivity for the detection of breast carcinomas smaller than 1 cm in diameter. There are other biologic and technical issues that remain to be overcome to optimally image the breasts. Some of these include: development of a dedicated breast imager using nuclear medicine techniques, development of stereotactic needle localization of the abnormalities that demonstrate focal increase uptake in women with normal mammogram and breast physical examination, manufacturing of a breast compression device so that they can immobilize the breast in place for more adequate imaging, overcoming the issue of unilateral or bilateral diffuse breast uptake that is noted in 7 - 10 percent of the cases and finally determination of optimal dose and imaging factors. This review includes their experience at Harbor-University of California, Los Angeles Medical Center with the use of this agent for breast imaging since 1992

    The method of three-dimensional display of hepatocellular carcinoma using conventional hepatic arteriogram by computer graphics method was newly exploited and applied in clinical use. Three-dimensional models were reconstructed from contour lines of tumors demonstrated as hypervascular lesions by hepatic arteriography. Although objects were limited by angiographic images in which tumors need to be demonstrated as nodules with hypervascularity, this method of three-dimensional display was not worse on accuracy than that using computed tomographic images. According to this method property of the tumor expressed by vascularity was demonstrated clear and in addition volume of the tumor was calculated easily. When the tumor arose in necrotic changes in which demonstrated as a vascular lesion by hepatic arteriography with reduction of size in usual by conservative treatment such as transcathter arterial embolization therapy, this three-dimensional display was able to demonstrate such changes clear. This preliminary study demonstrates the feasibility and clinical usefulness of three-dimensional display of hepatocellular carcinoma using hepatic arteriogram by computer graphics method. (author)

    Full Text Available Abstract Background Sentinel lymph node (SLN biopsy is the standard of care for the surgical assessment of the axilla during breast cancer surgery. However, the diagnostic accuracy of intraoperative frozen section analysis for confirming metastatic involvement of SLNs in cases of invasive lobular carcinoma (ILC versus that of invasive ductal carcinoma (IDC has generated controversy secondary to a frequently low-grade cytologic appearance and an often discohesive pattern displayed by metastatic lymph nodes in ILC. In the current report, we present a comparison of intraoperative frozen section analysis for confirming the presence of metastatic disease within SLNs during breast cancer surgery for ILC and IDC. Methods We evaluated the results of 131 consecutive cases of ILC from 1997 to 2008 and 133 cases of IDC (selected by a random sequence generator program from amongst 1163 consecutive cases of IDC from the same time period. All cases had at least one SLN that had both intraoperative frozen section analysis and confirmatory permanent section analysis performed. Results No statistically significant difference was found in the sensitivity (67% vs. 75%, P = 0.385, specificity (100% vs. 100%, accuracy (86% vs. 92%, P = 0.172, false negative rate (33% vs. 25%, P = 0.385, negative predictive value (81% vs. 89%, P = 0.158, and positive predictive value (100% vs. 100% for frozen section analysis for confirming the presence of metastatic disease within SLNs during breast cancer surgery for ILC and IDC. Conclusion Since there was no statistically significant difference in sensitivity, specificity, accuracy, false negative rate, negative predictive value, and positive predictive value between frozen section analysis of SLNs for patients with ILC and IDC, the clinical accuracy of confirming metastatic involvement of SLNs on frozen section analysis for ILC should not be considered inferior to the clinical accuracy for IDC. Therefore, frozen section analysis

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

    Full Text Available Abstract Background The coexistence of breast cancer and tuberculosis is very rare. This can create a dilemma in the diagnosis and treatment as there are no pathognomonic symptoms or signs to distinguish both diseases. Case presentation A female patient was seen in the breast clinic for a right breast lump. Clinical examination and investigation confirmed cancer and tuberculosis of the right breast. She underwent right mastectomy and axillary clearance and received chemo and radiotherapy. Unfortunately, she died of wide spread metastases. Conclusion The simultaneous occurrence of these two major illnesses in the breast can lead to many problems regarding diagnosis and treatment. Though rare, surgeons, pathologists and radiologists should be aware of such condition.

    Invasive lobular breast cancer (ILC) accounts for 10–15% of all invasive breast carcinomas. It is generally ER positive (ER+) and often associated with lobular carcinoma in situ (LCIS). Genome-wide association studies have identified more than 70 common polymorphisms that predispose to breast cancer, but these studies included predominantly ductal (IDC) carcinomas. To identify novel common polymorphisms that predispose to ILC and LCIS, we pooled data from 6,023 cases (5,622 ILC, 401 pure LCIS) and 34,271 controls from 36 studies genotyped using the iCOGS chip. Six novel SNPs most strongly associated with ILC/LCIS in the pooled analysis were genotyped in a further 516 lobular cases (482 ILC, 36 LCIS) and 1,467 controls. These analyses identified a lobular-specific SNP at 7q34 (rs11977670, OR (95%CI) for ILC = 1.13 (1.09–1.18), P = 6.0×10−10; P-het for ILC vs IDC ER+ tumors = 1.8×10−4). Of the 75 known breast cancer polymorphisms that were genotyped, 56 were associated with ILC and 15 with LCIS at Pbreast cancer specific predisposition polymorphism at 7q34, and shown for the first time that common breast cancer polymorphisms predispose to LCIS. We have shown that many of the ER+ breast cancer predisposition loci also predispose to ILC, although there is some heterogeneity between ER+ lobular and ER+ IDC tumors. These data provide evidence for overlapping, but distinct etiological pathways within ER+ breast cancer between morphological subtypes. PMID:24743323

    Full Text Available Acinic cell carcinoma of the breast is an extremely rare, malignant neoplasm characterized by widespread acinar cell-like differentiation and clinically low-grade malignancy. Herein, we report a case of acinic cell carcinoma of the breast in a 41-year-old woman. The tumor was poorly demarcated but had a firm consistency. It was removed with lumpectomy, and sentinel lymph node biopsy was performed to check for metastasis. Microscopically, the tumor showed an infiltrative growth pattern with a combination of solid, trabecular, and microglandular areas. Many of the tumor cells had abundant clear vacuolated cytoplasm containing zymogen-typed granules which resemble acinar cells of the salivary glands. The immunohistochemical profile of the tumor was also similar to that of salivary gland acinic cell carcinoma: the tumor cells were positive for amylase, lysozyme, α-1-antichymotrypsin, S-100 protein, and epithelial membrane antigen and negative for estrogen receptor, progesterone receptor, and human epidermal growth factor receptor 2. She received postoperative chemoradiation therapy and has been well for 3 years since surgery. As studies on large series are lacking, further studies are needed to elucidate the biological characteristics of acinic cell carcinoma of the breast.

    Whole chicken breast was injected with potassium bicarbonate (PB), sodium bicarbonate (SB), and potassium lactate (K-lactate) and salt, alone or in combination at different concentration levels. The objectives were to 1) investigate the effects of different concentration of PB, SB, and PL on instrumental color, water-holding capacity (WHC), objective tenderness, expressible moisture, and moisture content and 2) evaluate whether sodium-containing ingredients can be replaced with potassium as a potential strategy to reduce total sodium content in the finished product. Results showed that chicken breast tissue marinated with SB and PB had greater moisture retention, display characteristics, and cooked product qualities than chicken breast tissue injected with water and the nonmarinated control. The L* values (lightness) did not change over the period of retail display and were not different compared to the control (P>0.05). The chicken breast enhanced with SB, PB, and K-lactate retained better retail display color than the controls (marinated with water and nonmarinated). Increasing the potassium bicarbonate concentration from 0.5 to 1.5% significantly improved the water-holding capacity (82.17 to 92.61%; Pretail display and cooked meat quality than SB. This study suggests that chicken breast tissue can be marinated with KB as a healthier alternative to phosphate or SB. © 2015 Poultry Science Association Inc.

    Full Text Available Aim. Paclitaxel based neoadjuvant chemotherapy regimen (NAT in the setting of locally advanced breast cancer (LABC can render inoperable tumor (T4, N2/N3 resectable. The aim of this study was to assess the status of carcinoma in the breast and lymph nodes after paclitaxel based NAT in order to find out the patient and the tumor characteristics that correspond to the pathological responses which could be used as a surrogate biomarker to assess the treatment response. Materials and Methods. Clinical and tumor characteristics of patients with breast carcinoma (n=48 were assessed preoperatively. These patients were subjected to modified radical mastectomy after 3 courses of paclitaxel based NAT regimen. The pathological responses of the tumor in the breast and the lymph nodes were studied by using Chevallier’s system which graded the responses into pathological complete response (pCR, pathological partial response (pPR, and pathological no response (pNR. Results. Our studies showed a pCR of 27.1% and a pPR of 70.9% . Clinically small sized tumors (2–5 cms and Bloom Richardson’s grade 1 tumors showed a pCR. Mean age at presentation was 50.58 yrs. 79.2% of cases were invasive ductal carcinoma NOS; only 2.1% were invasive lobular carcinoma, their response to NAT being the same. There was no downgrading of the tumor grades after NAT. Ductal carcinoma in situ and lymphovascular invasion were found to be resistant to chemotherapy. The histopathological changes noted in the lymph nodes were similar to that found in the tumor bed. Discussion and Conclusion. From our study we conclude that histopathological examination of the tumor bed is the gold standard for assessing the chemotherapeutic tumor response. As previous studies have shown pCR can be used as a surrogate biomarker to assess the tumor response.

    2016-01-01

    Background: Gall bladder carcinoma is one of the most common cancers in India. Gall bladder cancer with metastasis to the breast is very rare. Herein we intend to report a case of carcinoma gall bladder with breast metastasis and a short review of the literature. Methods: This report describes an interesting and unusual case of gall bladder carcinoma presenting with breast metastasis. Case report: A 38-year lady presented with complaints of right abdominal pain. Bilateral breast examination showed 2 2 cm palpable lump in the upper outer quadrant of the left breast. Contrast-enhanced CT of the abdomen and pelvis showed circumferential thickening of gall bladder with the loss of fat plane with the adjacent liver parenchyma. Biopsy from the breast lump was reported as metastatic adenocarcinoma compatible with primary in the gall bladder. Whole body PET-CT showed gall bladder mass with abdominal and pelvic nodes with metastasis to liver, left breast, C7 vertebral body and left supra-clavicular node. She was diagnosed to have disseminated carcinoma gall bladder with liver, breast and supraclavicular nodal metastasis. She received palliative chemotherapy with gemcitabine and carboplatin and radiotherapy to C7 vertebra. After receiving 3 cycles of chemotherapy, chemotherapy was changed to the second line with single agent capecitabine. In spite of two lines of chemotherapy, she succumbed to disease progression and expired. Conclusion: There are limited examples of gall bladder adenocarcinoma with simultaneous metastasis to breast in the English literature. Our case showed an unusual dissemination of gall bladder cancer

  11. Characterization of ductal and lobular breast carcinomas using novel prolactin receptor isoform specific antibodies

    Heger Christopher D

    2010-12-01

    Full Text Available Abstract Background Prolactin is a polypeptide hormone responsible for proliferation and differentiation of the mammary gland. More recently, prolactin's role in mammary carcinogenesis has been studied with greater interest. Studies from our laboratory and from others have demonstrated that three specific isoforms of the prolactin receptor (PRLR are expressed in both normal and cancerous breast cells and tissues. Until now, reliable isoform specific antibodies have been lacking. We have prepared and characterized polyclonal antibodies against each of the human PRLR isoforms that can effectively be used to characterize human breast cancers. Methods Rabbits were immunized with synthetic peptides of isoform unique regions and immune sera affinity purified prior to validation by Western blot and immunohistochemical analyses. Sections of ductal and lobular carcinomas were stained with each affinity purified isoform specific antibody to determine expression patterns in breast cancer subclasses. Results We show that the rabbit antibodies have high titer and could specifically recognize each isoform of PRLR. Differences in PRLR isoform expression levels were observed and quantified using histosections from xenografts of established human breast cancer cells lines, and ductal and lobular carcinoma human biopsy specimens. In addition, these results were verified by real-time PCR with isoform specific primers. While nearly all tumors contained LF and SF1b, the majority (76% of ductal carcinoma biopsies expressed SF1a while the majority of lobular carcinomas lacked SF1a staining (72% and 27% had only low levels of expression. Conclusions Differences in the receptor isoform expression profiles may be critical to understanding the role of PRL in mammary tumorigenesis. Since these antibodies are specifically directed against each PRLR isoform, they are valuable tools for the evaluation of breast cancer PRLR content and have potential clinical importance in

    Host interactions with tumor cells contribute to tumor progression by several means. This study was done to determine whether mammary epithelium could interact with breast carcinoma by producing substances capable of inducing motility in the cancer cells. Conditioned medium of immortalized 184A1 mammary epithelium collected in serum-free conditions induced dose-dependent motility in the MCF-7 breast carcinoma cell line by both a semiquantitative scattering assay and a Boyden chamber assay. Purification of the motility factor revealed that it was laminin 332 (formerly laminin 5) by mass spectroscopy. A Western blot of the 184A1 conditioned medium using a polyclonal antibody confirmed the presence of laminin 332 in the conditioned medium. Blockage of the motility with antibodies to the laminin 332 and its receptor components, alpha(3) and beta(1) integrins, provided further evidence that tumor cell motility was caused by the laminin 332 in the conditioned medium. Invasion of MCF-7, BT-20, and MDA-MB-435 S was induced by purified laminin 332 and 184A1 conditioned medium and blocked by an anti-alpha(3) integrin antibody. Staining of carcinoma in situ from breast cancer specimens revealed that laminin 332 in the myoepithelium adjacent to the preinvasive cells provided a source of laminin 332 that could potentially encourage the earliest steps of stromal invasion. In metaplastic breast carcinomas, the presence of laminin 332-producing cells coexpressing alpha(3) integrin and the greater metastatic potential of tumors with higher laminin 332 levels suggest that laminin 332 expression is associated with aggressive features in these human breast cancers.

    Full Text Available The mechanism of progression from ductal carcinoma in situ (DCIS to invasive ductal carcinoma (IDC remains largely unknown. We compared gene expression in tumors with simultaneous DCIS and IDC to decipher how diverse proteins participate in the local invasive process.Twenty frozen tumor specimens with concurrent, but separated, DCIS and IDC were microdissected and evaluated. Total RNA was extracted and microarray analysis was performed using Affymetrix GeneChip® Human Gene 1.0 ST Arrays. Microarray data were validated by quantitative real time reverse transcription-PCR (qRT-PCR and immunohistochemistry. Controls included seven pure in situ carcinomas, eight fragments from normal breast tissue, and a series of mouse breast carcinomas (MMTV-PyMT.Fifty-six genes were differentially expressed between DCIS and IDC samples. The genes upregulated in IDC samples, and probably associated with invasion, were related to the epithelial-mesenchymal transition (ASPN, THBS2, FN1, SPARC, and COL11A1, cellular adhesion (GJB2, cell motility and progression (PLAUR, PLAU, BGN, ADAMTS16, and ENPP2, extracellular matrix degradation (MMP11, MMP13, and MMP14, and growth/proliferation (ST6GAL2. qRT-PCR confirmed the expression patterns of ASPN, GJB2, ENPP2, ST6GAL2, and TMBS10. Expression of the ASPN and GJB2 gene products was detected by immunohistochemistry in invasive carcinoma foci. The association of GJB2 protein expression with invasion was confirmed by qRT-PCR in mouse tumors (P < 0.05.Conclusions: The upregulation of ASPN and GJB2 may play important roles in local invasion of breast ductal carcinomas.

    Full Text Available Abstract Because metaplastic carcinoma of the breast encompasses a great variety of histopathology, diagnostic challenges abound, especially within the realm of cytology. The authors compiled and studied an eight-case series comprised of metaplastic breast carcinomas and lesions initially suspicious cytologically for metaplastic carcinoma in order to assess the degree of cytologic-histologic correlation and to identify recurring problematic themes surrounding the cytology-based diagnosis of this neoplasm. The cytologic and histologic slides from eight cases suspicious for metaplastic breast carcinoma diagnosed by fine needle aspiration (FNA were collected and analyzed through a seven-year retrospective search of case files at our institution. Based on cytologic characteristics, the cases were separated into three groups. Group 1 consisted of three cases presenting with poorly differentiated adenocarcinoma and squamoid components on FNA. Group 2 was composed of two cases that featured a monophasic, malignant ductal cell population on cytology, while the cytologic specimens for the third group of cases presented with a mesenchymal component with or without a malignant glandular constituent. Cytologic-histologic correlation was present in two of three cases demonstrating a mesenchymal component, and there was 100% sensitivity in the cytologic detection of those mesenchymal elements. However, in only one of three cases was there an accurate cytologic diagnosis of metaplastic carcinoma when squamoid changes were present on FNA. Both cases demonstrating only malignant glandular elements on cytologic specimens revealed an additional component of malignant squamous differentiation upon the examination of mastectomy-derived tissue. These results indicate that squamous-like changes identified on FNA should be interpreted with caution and that sampling error remains a problematic recurrence in cytology. Regardless, there appears to be promise concerning

    Invasive lobular carcinoma (ILC) is the second most common type of breast cancer accounting for 5%-15% of all the breast cancer cases. The present study was performed on 171 breast cancer patients from Balochistan registered in CENAR (Center for Nuclear Medicine and Radiotherapy), Quetta. Written consent was obtained from the patients. The history of the disease was taken from the patients, and the patients' enrollment files were retrieved. Of the 171 patients, 5 (2.96%) were diagnosed with ILC with tumor Grade II, and stage of the cancer reported was Grade III in all the 5 patients affected with ILC. ILC is the second most common type of breast cancer diagnosed with comparatively lower grade but almost reported infiltrating.

    Viruses including Epstein–Barr virus (EBV), a human equivalent of murine mammary tumour virus (MMTV) and human papillomavirus (HPV) have been implicated in the aetiology of human breast cancer. We report the presence of HPV DNA sequences in areolar tissue and tumour tissue samples from female patients with breast carcinoma. The presence of virus in the areolar–nipple complex suggests to us a potential pathogenic mechanism. Polymerase chain reaction (PCR) was undertaken to amplify HPV types in areolar and tumour tissue from breast cancer cases. In situ hybridisation supported the PCR findings and localised the virus in nipple, areolar and tumour tissue. Papillomavirus DNA was present in 25 of 29 samples of breast carcinoma and in 20 of 29 samples from the corresponding mamilla. The most prevalent type in both carcinomas and nipples was HPV 11, followed by HPV 6. Other types detected were HPV 16, 23, 27 and 57 (nipples and carcinomas), HPV 20, 21, 32, 37, 38, 66 and GA3-1 (nipples only) and HPV 3, 15, 24, 87 and DL473 (carcinomas only). Multiple types were demonstrated in seven carcinomas and ten nipple samples. The data demonstrate the occurrence of HPV in nipple and areolar tissues in patients with breast carcinoma. The authors postulate a retrograde ductular pattern of viral spread that may have pathogenic significance

    Full Text Available Metastatic spread of breast carcinoma to the colon and rectum is rare. We report the case of a patient treated for lobular breast carcinoma presenting 17 years later with metastatic breast cancer of the colon. A 63-year-old lady with a past history of right-sided invasive lobular carcinoma of the breast presented with persistent diarrhoea. Colonoscopy with biopsies revealed a benign-looking stricture at the rectosigmoid junction. A CT scan of the abdomen and pelvis revealed a benign-looking stricture in keeping with a probable diverticular stricture. A Hartmann procedure was performed and histology revealed a metastatic lobular carcinoma with oestrogen and progesterone receptor-positive status. Treatment was commenced with letrozole and the patient remains well under clinical surveillance. In a patient with a history of breast carcinoma who presents with gastrointestinal symptoms the possibility of gastrointestinal tract spread should always be considered. Endoscopic diagnosis may be misleading with pathological diagnosis only being made following surgical resection. A history of breast carcinoma must be declared to the histopathologist following surgical resection so that an accurate diagnosis is made and appropriate treatment is commenced.

    Full Text Available Extrapulmonary small cell carcinomas (EPSCC are extremely rare. Most reports indicate success with therapy directed at the tumor as if it was pulmonary small cell carcinoma Primary small cell carcinoma of the breast is an uncommon form of EPSCC. Differentiating between a primary small cell carcinoma of the breast from metastatic disease to the breast is very important. According to the literature, there have been approximately 70 cases reported worldwide. Of these cases, only two cases are documented in men. Prognosis is varied and depends on stage of disease at presentation. A combination of surgery, chemotherapy and/or radiation is required to adequately treat patients with small cell carcinoma of the breast. We present a case of a male patient diagnosed with stage IV non-small cell lung carcinoma first and then subsequently diagnosed with a concurrent small cell carcinoma of the breast responding to treatment with concurrent chemotherapy and radiation.

    Abstract Our aim was to assess the feasibility and accuracy of contrast-enhanced ultrasound (CEUS) of the breast with SonoVue microbubbles for pre-operative size measurement of invasive breast carcinomas. Seven patients diagnosed with nine invasive breast carcinomas prospectively underwent gray-scale ultrasound and CEUS of the breast according to a standardized protocol. CEUS of the breast was performed by a Philips iU22 scanner equipped with a 4–8 MHz linear array transducer. We used a single dose of 2.4 ml SonoVue as contrast agent. Breast lesion morphology was scored according to the sonographic BI-RADS lexicon criteria and classified accordingly. The greatest tumor dimensions on gray-scale ultrasound and CEUS of the breast were finally compared with the greatest histopathologic tumor sizes. Gray-scale ultrasound underestimated the histopathologic tumor size in 6/9 cases (67%), whereas CEUS of the breast underestimated tumor size in only 3/9 (33%) cases. CEUS of the breast was significantly more accurate for tumor size assessment. Greatest tumor dimension as measured with gray-scale ultrasound of the breast was within 2 mm of the pathologic tumor size in only 2/9 cases (22%), whereas CEUS of the breast accurately assessed tumor size within 2 mm of pathologic tumor size in 6/9 (67%) of the cases (P<0.05). CEUS of the breast proved to be a feasible and safe procedure. It is more accurate than gray-scale ultrasound of the breast for pre-operative size assessment of invasive ductal breast carcinomas.

    Full Text Available INTRODUCTION : Breast carcinoma is the most common malignant tumor and the leading cause of death in women worldwide 1 . It accounts for 15 % of all cancer deaths 2 . According to the World Health Organisation (WHO, approximately 70% of breast cancers occur in women with none of the known risk factors. Only about 5% of breast cancers are inherited. Various protocols are in use for the assessment of prognosis, and also to assist further management of these cases. Of various parameters, expression of hormonereceptors Estrogen receptor (ER and Progesterone receptor (PR ar e significant AIMS AND OBJECTIVES : To study the occurrence of ER and PR status in breast cancer patients attending S.V.R.R.G.G. Hospital. To correlate the expression of prognostic factors like age at presentation menarche, menopause, parity, tumor size, number of lymph nodes, metastasis histology, grading with ER and PR status. MATERIALS AND METHODS : This clinic opathological study of carcinoma breast was carried out in patients admitted to SVRRGG Hospital, Tirupati during the period from September 2011 to August 2013 after obtaining approval from scientific committee and ethical committee .Forty cases of breast carcinoma were taken into study.

    Full Text Available Primary neuroendocrine carcinomas of the breast are extremely rare. Neuroendocrine tumors mainly occur in the broncopolmonary system and gastrointestinal tract. The diagnosis of small cell neuroendocrine carcinoma (SCNC of the breast can only be made if a non mammary site is excluded or if an in situ component can be found. We are going to describe two cases and to discuss their clinical, radiological and pathological manifestations. Introduction: Neuroendocrine tumors are rare and slow-growing neoplasias derived from neuroendocrine cells. We describe two cases of small cell neuroendocrine carcinoma of the breast and discuss their clinical, radiological and pathological manifestations. Case report: Our patients are two Italian females (38 and 36 year-old with no family history of breast disease. In both cases the diagnosis was confirmed after surgery, when immunohistochemistry revealed a neuroendocrine differentiation of the tumor. The patients are alive and disease free after more than ten years of follow-up. Conclusion: Primary neuroendocrine carcinomas of the breast are extremely rare. The diagnosis of SCNC of the breast can only be made if a non mammary site is excluded or if an in situ component can be found. After surgery, a strict follow-up including octreotide scan should be performed and this doesn’t differ from the one of the usual breast carcinoma.

    Glycogen-rich clear cell carcinoma (GRCC) of the breast is a rare type of breast carcinoma. Knowledge about the characteristics of this type is fragmentary, and the prognosis is on debate. In this study, we aimed to summarize the clinical, pathologic, and biologic characteristics of GRCC of the breast and analyze the survival. We reviewed the cases of breast cancer in our hospital between January 1999 and December 2009 and identified 28 patients as GRCC of the breast. The routine hematoxylin-eosin staining, periodic acid-Schiff (PAS) staining, and diastase PAS staining were performed on the tumor tissues. The expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2), Ki67 and P53 were evaluated by immunohistochemistry. Tumors with a HER-2 score of 2+ were confirmed by fluorescent in situ hybridization test. Each GRCC case, who had complete follow-up data, was compared with four cases of usual invasive ductal carcinomas as controls in the same database and matched with age, year of diagnosis, tumor size, nodal status, and immunophenotype. The chi-squared test and the Fisher's exact test were used to compare the characteristics of GRCC cases and controls. The univariate analysis was used to study the prognosis, and Kaplan-Meier method was used to compare the survival of two groups. The clinicopathologic and imaging features were analyzed in the GRCC cases. Tumor sizes ranged from 0.8 to 7.5 cm (mean, 3.2 cm). Thirteen cases (46.4%) had positive lymph nodes. The positivity of ER and PR was 61.5% (16 of 26). HER-2 was positive for three cases (12%). The positivity of Ki67 and P53 were 87.5% and 45.8%, respectively. Twenty-four cases were followed up from 19 to 158 months. The prognosis of GRCC of the breast was significantly related with the number of positive lymph nodes (p free survival (p = 0.900) between GRCC of the breast and the usual invasive ductal carcinomas. GRCC of the breast may not have a worse

    Breast cancer risk estimates for atypical lesions are based primarily on case-control studies of patients with open biopsies. The authors report the cumulative breast cancer incidence after a core biopsy diagnosis of atypical hyperplasia (ductal or lobular) or lobular carcinoma in situ. A cohort study with central pathology review was conducted on 393 patients who had core biopsy diagnoses of atypical hyperplasia and lobular carcinoma in situ from 1995 through 2010. Follow-up was available for 255 of 264 patients (97%) at a median of 87 months (range, 3-236 months). There were 212 patients (54%) who were not upgraded on excision and had no personal history of breast cancer. Of these, 21 of 212 (9.9%) developed breast cancer, including 15 invasive carcinomas, 4 ductal carcinomas in situ, 1 pleomorphic lobular carcinoma in situ, and 1 unknown type. The prior core biopsy diagnoses were atypical ductal hyperplasia for 11 patients (52%) and atypical lobular hyperplasia/lobular carcinoma in situ in the remaining 10 patients (48%). The number of atypical foci in the core biopsy was not significantly associated with the subsequent development of breast cancer (P = .42). Of the 15 invasive carcinomas, 11 (73%) were ipsilateral, 11 (73%) were pathologic T1 tumors, 5 (33%) were pathologic N1 tumors, 13 (87%) were estrogen receptor-positive, and 1 (7%) was amplified for human epidermal growth factor receptor 2. In patients who had an initial diagnosis of atypical hyperplasia or lobular carcinoma in situ on core biopsy, the 7-year cumulative breast cancer incidence was 9.9%. Most tumors were ipsilateral, stage I, estrogen receptor-positive, invasive carcinomas. The current data support close clinical and radiologic follow-up for more than 5 years in this patient population.

    Paraneoplastic neurological disorders are rare complications of breast carcinoma. Lambert-Eaton Myasthenic Syndrome (LEMS) is most commonly associated with small cell lung cancer. However, a combination of LEMS and subacute cerebellar degeneration as paraneoplastic syndromes is extremely rare, and has never been described in association with breast cancer.

  11. Cytoplasmic Skp2 expression is associated with p-Akt1 and predicts poor prognosis in human breast carcinomas.

    Directory of Open Access Journals (Sweden)

    Jing Liu

    Full Text Available BACKGROUND: S-phase kinase protein 2 (Skp2, an oncogenic protein, is a key regulator in different cellular and molecular processes, through ubiquitin-proteasome degradation pathway. Increased levels of Skp2 are observed in various types of cancer and associated with poor prognosis. However, in human breast carcinomas, the underlying mechanism and prognostic significance of cytoplasmic Skp2 is still undefined. METHODS: To investigate the role of cytoplasmic Skp2 expression in human breast carcinomas, we immnohistochemically assessed cytoplasmic Skp2, p-Akt1, and p27 expression in 251 patients with invasive ductal carcinomas of the breast. Association of cytoplasmic Skp2 expression with p-Akt1 and p27 was analyzed as well as correspondence with other clinicopathological parameters. Disease-free survival and overall survival were determined based on the Kaplan-Meier method and Cox regression models. RESULTS: Cytoplasmic of Skp2 was detected in 165 out of 251 (65.7% patients. Cytoplasmic Skp2 expression was associated with larger tumor size, more advanced histological grade, and positive HER2 expression. Increased cytoplasmic Skp2 expression correlated with p-Akt1 expression, with 54.2% (51/94 of low p-Akt1-expressing breast carcinomas, but 72.6% (114/157 of high p-Akt1-expressing breast carcinomas exhibiting cytoplasmic Skp2 expression. Elevated cytoplasmic Skp2 expression with low p-Akt1 expression was associated with poor disease-free and overall survival (DFS and OS, and Cox regression models demonstrated that cytoplasmic Skp2 expression was an independent prognostic marker for invasive breast carcinomas. CONCLUSION: Cytoplasmic Skp2 expression is associated with aggressive prognostic factors, such as larger tumor size, and advanced histological grade of the breast cancers. Results demonstrate that combined cytoplasmic Skp2 and p-Akt1 expression may be prognostic for patients with invasive breast carcinomas, and cytoplasmic Skp2 may serve as a

    CHEK2*1100delC is a moderate-risk breast cancer susceptibility allele with a high prevalence in the Netherlands. We performed copy number and gene expression profiling to investigate whether CHEK2*1100delC breast cancers harbor characteristic genomic aberrations, as seen for BRCA1 mutated breast cancers. We performed high-resolution SNP array and gene expression profiling of 120 familial breast carcinomas selected from a larger cohort of 155 familial breast tumors, including BRCA1, BRCA2, and CHEK2 mutant tumors. Gene expression analyses based on a mRNA immune signature was used to identify samples with relative low amounts of tumor infiltrating lymphocytes (TILs), which were previously found to disturb tumor copy number and LOH (loss of heterozygosity) profiling. We specifically compared the genomic and gene expression profiles of CHEK2*1100delC breast cancers (n = 14) with BRCAX (familial non-BRCA1/BRCA2/CHEK2*1100delC mutated) breast cancers (n = 34) of the luminal intrinsic subtypes for which both SNP-array and gene expression data is available. High amounts of TILs were found in a relatively small number of luminal breast cancers as compared to breast cancers of the basal-like subtype. As expected, these samples mostly have very few copy number aberrations and no detectable regions of LOH. By unsupervised hierarchical clustering of copy number data we observed a great degree of heterogeneity amongst the CHEK2*1100delC breast cancers, comparable to the BRCAX breast cancers. Furthermore, copy number aberrations were mostly seen at low frequencies in both the CHEK2*1100delC and BRCAX group of breast cancers. However, supervised class comparison identified copy number loss of chromosomal arm 1p to be associated with CHEK2*1100delC status. In conclusion, in contrast to basal-like BRCA1 mutated breast cancers, no apparent specific somatic copy number aberration (CNA) profile for CHEK2*1100delC breast cancers was found. With the possible exception of copy number loss

    A retrospective study of two methods of ovarian ablation as primary therapy for metastatic carcinoma of the breast was carried out using records from this cancer institute. Sixty-one radiation and 97 surgical ovarian ablations, performed from 1972 to 1977, were assessed. Over-all response was similar for the surgical and irradiation groups. Survival from the time of ovarian ablation was greater in both groups in those who responded positively than in those who did not. Factors other than estrogen receptor status can determine the response of patients with metastatic carcinoma of the breast to ovarian ablation. The results indicate that clinical determinates and not the efficiency of one method over the other should be the main criteria for choosing between ovarian ablation by irradiation or by oophorectomy

    2017-08-01

    We present a case of a 71-year-old woman with recurrent stroke episodes due to non-bacterial thrombotic endocarditis (NBTE) leading to the diagnosis of an early-stage breast carcinoma. NBTE is associated with a variety of inflammatory states, including malignancy. NBTE presents itself with systemic embolization, mostly stroke. Treatment consists of treating the underlying condition and start of systemic anticoagulation therapy. Cardiac surgery is restricted to highly selected cases, since prognosis usually is limited by the neoplasm, which usually is in an advanced stage at time of diagnosis of NBTE. The malignancy usually is diagnosed prior to NBTE. Cases presenting with NBTE leading to the diagnosis of malignancy, however, are rarely reported. To our knowledge, we present the first case leading to the diagnosis of an early-stage breast carcinoma.

    Full Text Available There is evidence that breast cancer is a heterogeneous disease phenotypically as well as molecular biologically. So far, heterogeneity on the molecular biological level has not been investigated in potential precursor lesions, such as ductal hyperplasia (DH and ductal carcinoma in situ (DCIS. In this study we applied comparative genomic hybridization (CGH to formalin‐fixed, paraffin‐embedded breast tissue with DH and DCIS, adjacent to invasive ductal carcinoma (IDC, to screen these potential precursor lesions for whole genomic chromosomal imbalances. Laser‐microdissection was used to select pure cell populations from the sections. Isolated DNA was amplified by degenerate oligonucleotide primed PCR (DOP‐PCR and further processed for CGH analysis.

    2018-01-01

    Full Text Available We report here on a case of 51-year-old woman with metastatic small cell carcinoma of the breast that came from her cancer of the uterine cervix. She underwent radical hysterectomy with bilateral salpingo-oophorectomy due to small cell carcinoma of the uterine cervix, and adjuvant radiotherapy was administered to the pelvis. Breast metastasis with a palpable mass then occurred 3 months after the primary surgery. Simple mastectomy and adjuvant chemotherapy were performed. She initially showed a good response to the therapy, yet she ultimately died of multiple metastases with a fulminating disease course. This is an extremely rare case, and only 1 similar case has been reported earlier, so we report on this case along with a review of the relevant literature.

    Low megavolt electron beam therapy was used to treat 68 women and one man with recurrent carcinoma of the breast on the chest wall. Photon irradiation had been used previously in 53 patients. Of the 63 patients who survived 2 months or longer after electron irradiation, 59 (94%) achieved a complete response. Persistent radiation ulcers developed in only 2 patients (3%). No other late radiation complications were observed. Nineteen patients (28%) survived 3 years after electron irradiation, with a median survival of 54 months. In this group, disease eventually recurred in all patients who received a calculated NSD of less than 1400 ret; no disease recurred in the patients who received doses greater than 1400 ret. It is concluded that megavolt electron irradiation is effective in the treatment of chest wall recurrence from carcinoma of the breast and is safe even in patients who have had a previous course of photon irradiation.

    Full Text Available Cutaneous metastasis may correspond to the initial clinical presentation of hidden internal malignancies. In patients presenting said neoplasia, clinical manifestations of breast cancer reaches 23.9%. Considering that neoplastic alopecia appears as an unusual pattern of the said metastasis, this report describes a case of such uncommon neoplastic alopecia which presents itself as a cutaneous metastasis of rapid progression in a patient with prior breast cancer history. We present a 47-year-old female patient reporting lesions at the scalp, and who was asymptomatic with a 1-year evolution. The patient reported prior breast cancer history and presence of lung metastasis, and was undergoing chemotherapy at the time of consultation. A dermatological evaluation showed only a nodular lesion with erythematous surface and a diameter measuring about 4 cm, firm in consistency, and immovable. She was routed to the Department of Dermatological Surgery, and the results from histopathology were consistent with a diagnosis of metastatic breast adenocarcinoma. Neoplastic alopecia appears as an unusual form of cutaneous metastasis which is predominantly described in association with breast cancer. The lesion’s clinical features play a crucial role at the differential diagnosis, as the presence of erythema could distinguish neoplastic alopecia from alopecia areata. The existence of cutaneous metastasis leads to unfavorable outcomes. As a conclusion, cutaneous evaluation of patients is essential for treating visceral metastases, since the forms of cutaneous metastasis are diverse and can also affect the scalp.

    Purpose: The purpose of this study was to evaluate the relationship between a family history of breast or ovarian cancer and outcome after breast-conserving surgery and radiation in women presenting with an initial diagnosis of ductal carcinoma in situ (DCIS) of the breast. Methods and Materials: A total of 146 consecutive women with a pathologic diagnosis of ductal carcinoma in situ as their first diagnosis of any breast cancer were identified; 28 (19%) had a positive family history of breast or ovarian cancer in a first-degree relative, 27 (19%) had a positive family history in a second-degree relative, and 91 (62%) had no family history. Pathologic, clinical, and treatment factors, and clinical outcomes for each family history group were compared. Cosmesis and complications were recorded at each follow-up. Patients were treated between 1978 and 1995, and the median follow-up was 7.1 years. Results: Patients with a positive family history in a first- or second-degree relative each had an 8% incidence of local failure at 10 years, while the negative family history group demonstrated a 16% local failure rate (p = 0.33). Overall survival at 10 years for patients with a positive family history in a first- or second-degree relative was 100% and for those with a negative family history was 91% (p = 0.08). The negative family history group had a higher median age that may account for the difference in overall survival. Cause-specific survival (CSS) was 97%, 100%, and 99%, respectively, at 10 years (p = 0.25). There were no differences in the cosmetic results or complication rates between women with a positive or negative family history. Conclusion: We have shown that a family history of breast and/or ovarian cancer is not associated with an adverse outcome for women treated with breast conservation therapy for DCIS. Local recurrence, cause-specific survival, overall survival, cosmesis, and complication rates were comparable to that of similarly treated women with

    Intracystic papillary carcinoma (IPC) of the breast is very rare, and it has a much better prognosis than the other types of breast carcinoma. We experienced a case of intracystic papillary carcinoma that we diagnosed in an 83-year-old-woman. MR imaging of the IPC shows a multicystic appearance with a subacute or chronic stage of intracystic hemorrhage. The contrast-enhanced MR imaging demonstrates enhancement of the cyst wall and mural nodules, and this modality proved to be successful for making an accurate preoperative diagnosis

    Full Text Available Abstract Introduction Tumors can metastasize to the oral cavity and affect the jaws, soft tissue and salivary glands. Oral cavity metastases are considered rare and represent approximately 1% of all oral malignancies. Because of their rarity and atypical clinical and radiographic appearance, metastatic lesions are considered a diagnostic challenge. The purpose of this report is to present a rare case of a metastatic breast carcinoma mimicking a periodontal abscess in the mandible. Case presentation A 55-year-old Caucasian woman was referred to our clinic for evaluation of bisphosphonate-induced jaw osteonecrosis. She had undergone modified radical mastectomy with axillary lymph node dissection for invasive ductal carcinoma of the left breast. Her clinical examination showed diffuse swelling and a periodontal pocket of 6 mm exhibiting suppuration in the posterior right mandible. Moreover, paresthesia of the lower right lip and chin was noted. There were no significant radiographic findings other than alveolar bone loss due to her periodontal disease. Although the lesion resembled a periodontal abscess, metastatic carcinoma of the breast was suspected on the basis of the patient's medical history. The area was biopsied, and histological analysis confirmed the final diagnosis of metastatic breast carcinoma. Conclusion The general dentist or dental specialist should maintain a high level of suspicion while evaluating patients with a history of cancer. Paresthesias of the lower lip and the chin should be considered ominous signs of metastatic disease. This case highlights the importance of the value of a detailed medical history and thorough clinical examination for the early detection of metastatic tumors in the oral cavity.

    Using an antiserum against carcinoembryonic antigen, which was free from non-specific cross-reacting antigen activity, carcinoembryonic antigen has been demonstrated in 45 out of 90 breast carcinomas by an indirect three-stage immunoperoxidase method. The presence of carcinoembryonic antigen appears to be related to good histological differentiation but not to histological type, lymph node metastasis, or recurrence within two years of primary diagnosis. It is suggested that the varying result...

    Indium is generally presumed to localize in the bone marrow within the erythroid cell line. Fibrosis, inflammation, lymphoma, extended field radiation, chemotherapy, or combinations of both treatment modalities generally depress the uptake of indium by the marrow in a complex fashion. We report a case of metastatic breast carcinoma and pancytopenia in which the In-111 scan appeared qualitatively similar to a Tc-99m MDP bone scan. Findings were confirmed by bone marrow biopsy

    Basal-like breast carcinomas often are regarded for circumscribed solitary lesions having unfavorable prognosis. On the other hand, a considerable proportion of breast carcinomas is multifocal and has increased metastatic potential. In this study, we analyzed the subgross distribution of the lesions in a series of basal-like carcinomas, compared it with that in nonbasal-like tumors and studied the frequency of vascular invasion and lymph node metastasis in relation to focality of the lesions. A total of 511 consecutive cases documented in large-format histologic sections were studied. Tumors expressing at least one of the basal (myoepithelial) markers (CK5/6, CK14, EGFR) in at least one of the invasive tumor foci were categorized as basal-like tumors. Triple-negative (ER/PR/HER-2-negative) basal-like carcinomas also were analyzed. The distribution of lesions and the frequency of vascular invasion and lymph node metastasis were analyzed. The study was approved by the Regional Ethical Committee Uppsala-Örebro. In 44% of cases, the invasive component was multifocal or diffuse. Combining the in situ and invasive tumor components resulted in 61% of cases with multifocal/diffuse distribution. The only statistically significant difference observed was that basal-like tumors lacked in situ components more often (21% vs. 9%; P = 0.0075). No significant differences could be demonstrated regarding vascular invasion and lymph node status. Lymph node metastasis appeared significantly more frequently in multifocal cases in both tumor categories. Basal-like breast carcinomas are as frequently multifocal as their non-basal-like counterparts; multifocality is associated with increased risk for vascular invasion and lymph node metastasis in both tumor categories.

    Invasive ductal carcinoma with lobular features (IDC-L) is not recognized as a distinct subtype of breast cancer, and its clinicopathologic features and outcomes are unknown. In this retrospective study, we focused on characterization of clinicopathologic features and outcomes of IDC-L and compared them to invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC). 183 cases of IDC-L from 1996 to 2011 were compared with 1,499 cases of IDC and 375 cases of ILC. Available slides of IDC-L (n = 150) were reviewed to quantify the lobular component (≤ 20, 21-50, 51-80, >80 %), defined as small cells individually dispersed, arranged in linear cords, or in loose aggregates without the formation of tubules or cohesive nests. E-cadherin immunostain was performed to confirm ductal origin. Compared to IDC, IDC-L was more likely to have lower histologic grade (p lobular component in IDC-L had no impact on the size, nodal status, stage, or outcome. Our data suggest that although IDC-L may be a variant of IDC, with >90 % of cases being E-cadherin positive, the clinical and biological characteristics are more similar to that of ILC.

    Pure mucinous breast carcinoma (PMBC) is an uncommon histological type of breast cancer characterized by a large amount of mucin production. MicroRNA (miRNA) is a large class of small noncoding RNA of about 22 nt involved in the regulation of various biological processes. This study aims to identify the miRNA expression profile in PMBC. MiRNA expression profiles in 11 PMBCs were analyzed by miRNA-microarray and real-time polymerase chain reaction (PCR). Thirty-one PMBCs and 27 invasive ductal carcinoma of no special types (IDC-NSTs) were assessed by immunohistochemistry using antibodies against ER, PR-progesterone receptor, HER2, Ki-67, Bcl-2, p53, PCNA, and CK5 and 6. We analyzed the miRNA expression in 11 PMBCs and corresponding normal tissues using miRNA-microarray and real-time PCR, and found that miR-143 and miR-224-5p were significantly downregulated in mucinous carcinoma tissue. Compared with IDC-NSTs, PMBC showed a significantly higher ER positive rate, lower HER-2 positive rate, and lower cell proliferation rates. To our knowledge, this is the first study to demonstrate the miRNA expression profile of PMBC, and our findings may lead to further understanding of this type of breast cancer

    Breast carcinoma is an unpredictable disease in the sense that some patients may die at early disease stage due to wide-spread metastasis within six months to one year, while others may survive longer. This study was aimed to evaluate the risk factors for breast carcinoma occurrence and histopathological features of breast carcinoma developed in the social and economical conditions of Pakistan. Methods: A total of 224 female breast cancer diagnosed patients with uncovered medical insurance visiting at the Oncology clinic of a teaching hospital at Karachi, Pakistan were selected for the study. Two hundred and twenty-four (224) healthy female subjects free of any cancer diagnosis were selected as control from different areas of the city. Information on stress, occupation, life history, and life style was obtained through personal interviews. Breast tumour pathology was evaluated for histological grade, lymph node metastasis and hormone receptor status by using standard methods. Student's t-test, Chi-square test and ANOVA were used for comparison. Results: Breast cancer patients in significantly high percentage reported early marriages, abortion occurrence, stressful life style, family cancer history and past disease suffering from diabetes and hypertension. Life style including aerosol chewing and fat rich food intake was significantly high among the patients (p<0.05). On histopathological analysis, patients at the age of 40 years and below were identified in significantly high percentage with tumour grade III, 1-3 lymph node metastasis and hormone receptor negative type. Increasing age was associated with low tumour grade and less percentage of lymph node metastasis. Significantly high percentage of patients were presented with hormone receptor positive tumour (p<0.05). Conclusion: The contributing factors for breast carcinoma occurrence were related to life history and life-style of the patients. Medical insurance uncovered patients at initial diagnosis were

    In 1979 histologically confirmed cases of carcinoma of the breast the diagnostic values of clinical examination, mammography and aspiration biopsy were compared. The effect of combining these three diagnostic methods was evaluated. Clinical examination and mammography each produced a positive diagnosis in 89% of the cases, and in 88% aspiration biopsy. A combination of these three methods enabled a positive diagnosis of carcinoma of the breast in 99% of the cases. Fine needle biopsy and mammography carried out by the clinician seem to be as effective as when done by the cytologist and diagnostic radiologist. A combination of clinical examination, mammography and aspiration biopsy increases the diagnostic accuracy of breast cancer. (orig.) [de

    We have investigated the effects of laminin, on the plasminogen-activator system of MCF-7 breast-carcinoma cells. MCF-7 cells were incubated on plastic or laminin-coated wells, and medium and cell lysate aliquots were assayed for tissue-type (tPA) and urokinase-type plasminogen activator (uPA) by a chromogenic assay in combination with anti-uPA antibodies. Cells cultured on laminin displayed a 5-fold increase in tPA activity and a 2-fold decrease in uPA activity relative to cells on plastic. These effects could be mimicked by laminin fragment P1 but not by collagen I or fibronectin. tPA activity of cells treated with estradiol (10 nM) was 3-fold higher, that of cells on laminin treated with estradiol was 15-fold higher, than that of control. Northern-blot analysis showed that tPA mRNA levels were up-regulated by estradiol and laminin, whereas PAI-1 mRNA levels were down-regulated by laminin and not affected by E2. Concomitant treatment with laminin and estradiol, decreased PAI-1 mRNA and increased tPA mRNA levels, accounting for the synergistic increase in tPA activity. Laminin exerted only a modest (approx. 2-fold) inhibitory effect on uPA mRNA levels. In the breast-carcinoma cell line MDA-MB-231, down-regulation of PAI-1 and uPA mRNA by laminin was not observed. Adhesion assays indicated that alpha2beta1 is the predominant receptor for laminin in MCF-7 cells. MDA-MB-231 cells expressed alpha2 (54%) but this integrin is not used as a laminin receptor. These results support a role for alpha2beta1 in mediating interactions of MCF-7 with LN.

    We previously established a rapid three-dimensional assay for discrimination of normal and malignant human breast epithelial cells using a laminin-rich reconstituted basement membrane. In this assay, normal epithelial cells differentiate into well-organized acinar structures whereas tumor cells fail to recapitulate this process and produce large, disordered colonies. The data suggest that breast acinar morphogenesis and differentiation is regulated by cell-extracellular matrix (ECM) interactions and that these interactions are altered in malignancy. Here, we investigated the role of ECM receptors (integrins) in these processes and report on the expression and function of potential laminin receptors in normal and tumorigenic breast epithelial cells. Immmunocytochemical analysis showed that normal and carcinoma cells in a three-dimensional substratum express profiles of integrins similar to normal and malignant breast tissues in situ. Normal cells express {alpha}1, {alpha}2, {alpha}3, {alpha}6, {beta}1 and {beta}4 integrin subunits, whereas breast carcinoma cells show variable losses, disordered expression, or down regulation of these subunits. Function-blocking experiments using inhibitory antiintegrin subunit antibodies showed a >5-fold inhibition of the formation of acinar structures by normal cells in the presence of either anti-{beta}1 or anti-{alpha}3 antibodies, whereas anti-{alpha}2 or -{alpha}6 had little or no effect. In experiments where collagen type I gels were used instead of basement membrane, acinar morphogenesis was blocked by anti-{beta}1 and -{alpha}2 antibodies but not by anti-{alpha}3. These data suggest a specificity of integrin utilization dependent on the ECM ligands encountered by the cell. The interruption of normal acinar morphogenesis by anti-integrin antibodies was associated with an inhibition of cell growth and induction of apoptosis. Function-blocking antibodies had no inhibitory effect on the rate of tumor cell growth, survival or

    CD40L was found to reduce doxorubicin-induced apoptosis in non Hodgkin's lymphoma cell lines through caspase-3 dependent mechanism. Whether this represents a general mechanism for other tumor types is unknown. The resistance induced by CD40L against apoptosis induced by a panel of cytotoxic chemotherapeutic drugs in non Hodgkin's lymphoma and breast carcinoma cell lines was investigated. Doxorubicin, cisplatyl, etoposide, vinblastin and paclitaxel increased apoptosis in a dose-dependent manner in breast carcinoma as well as in non Hodgkin's lymphoma cell lines. Co-culture with irradiated L cells expressing CD40L significantly reduced the percentage of apoptotic cells in breast carcinoma and non Hodgkin's lymphoma cell lines treated with these drugs. In breast carcinoma cell lines, these 5 drugs induced an inconsistent increase of caspase-3/7 activity, while in non Hodgkin's lymphoma cell lines all 5 drugs increased caspase-3/7 activity up to 28-fold above baseline. Co-culture with CD40L L cells reduced (-39% to -89%) the activation of caspase-3/7 induced by these agents in all 5 non Hodgkin's lymphoma cell lines, but in none of the 2 breast carcinoma cell lines. Co culture with CD40L L cells also blocked the apoptosis induced by exogenous ceramides in breast carcinoma and non Hodgkin's lymphoma cell lines through a caspase-3-like, 8-like and 9-like dependent pathways. These results indicate that CD40L expressed on adjacent non tumoral cells induces multidrug resistance to cytotoxic agents and ceramides in both breast carcinoma and non Hodgkin's lymphoma cell lines, albeit through a caspase independent and dependent pathway respectively

    This study assessed whether age-related differences in breast carcinoma knowledge and perceived risk exist among women in a primary care setting and whether these women's beliefs about the best age to begin screening mammography reflect those of their physicians. Consecutive women ages 30-70 years who visited an academic general medicine practice were asked to complete a questionnaire assessing breast carcinoma knowledge, beliefs, and perceived risk. Women's risk estimates were compared with individual risk probabilities derived from the Gail model. Women's beliefs about when to begin screening mammography were compared with the beliefs of the attending physicians in the practice. Questionnaire results were compared across age groups. Six hundred seventy-four women completed the survey. Overall, knowledge scores were negatively correlated with age (correlation coefficient = -0.30, P = 0.001). The level of knowledge about the benefits of mammography was high across all age groups. In contrast, knowledge that breast carcinoma incidence increases with age was poor. Only 28% of all women recognized that breast carcinoma is more common among women age 65 years than among women age 40 years. Among all women, 26% underestimated their risk of developing breast carcinoma in the next 10 years, 32% correctly estimated their risk, and 42% overestimated their risk. Fifty-five percent thought that mammography should begin when a woman is age 30-35 years. In contrast, all surveyed physicians recommended that a woman start undergoing mammography at age 40 years or older. In this primary care setting, older women had poorer breast carcinoma knowledge than younger women but were equally likely to appreciate the benefits of mammography. Most women were unaware that age is a risk factor for breast carcinoma. Improved education of females by their physicians may resolve some of the observed discrepancies regarding the optimal age to begin screening mammography.

    Full Text Available Breast cancer (BC is the second most common cancer diagnosed in American women and is also the second leading cause of cancer death in women. Research has focused heavily on BC metastasis. Multiple signaling pathways have been implicated in regulating BC metastasis. Our knowledge of regulation of BC metastasis is, however, far from complete. Identification of new factors during metastasis is an essential step towards future therapy. Our labs have focused on Semaphorin 6D (SEMA6D, which was implicated in immune responses, heart development, and neurogenesis. It will be interesting to know SEMA6D-related genomic expression profile and its implications in clinical outcome. In this study, we examined the public datasets of breast invasive carcinoma from The Cancer Genome Atlas (TCGA. We analyzed the expression of SEMA6D along with its related genes, their functions, pathways, and potential as copredictors for BC patients’ survival. We found 6-gene expression profile that can be used as such predictors. Our study provides evidences for the first time that breast invasive carcinoma may contain a subtype based on SEMA6D expression. The expression of SEMA6D gene may play an important role in promoting patient survival, especially among triple negative breast cancer patients.

    Invasive Lobular Carcinoma (ILC) is frequently a mammographic and diagnostic dilemma; thus any additional information that CAD (Computer-Aided Detection) systems can give radiologists may be helpful. Our study was to evaluate the role of CAD numeric values as indicators of malignancy and the effect of breast density in the diagnosis of ILC. Eighty consecutive biopsy-proven ILC cases with CAD (ImageChecker {sup registered}, Hologic vertical stroke R2, Santa Clara, CA, versions 2.3, 3.1, 3.2, 5.0, 5.2) diagnosed between June 2002 and December 2004 were retrospectively reviewed. Data included: BIRADS {sup registered} breast density, whether CAD marked the cancer at diagnosis year or years prior, and lesion type. Study mammograms underwent additional CAD scans (Image Checker {sup registered} V5.3, V8.0, V8.1) to obtain a numeric value associated with each marker, low values represent increasingly suspicious features. CAD correctly marked 65% (52/80) of ILC cases, detection was found to decrease with increased breast density. Numeric values of CAD marks at sites of carcinoma showed median score of 171 (range 0 - 1121). The CAD marker may potentially be used as an additional indicator of suspicious lesion features in all breast densities and higher likelihood that an area on the mammogram requires further investigation.

    Full Text Available Invasive lobular breast cancer (ILC accounts for 10-15% of all invasive breast carcinomas. It is generally ER positive (ER+ and often associated with lobular carcinoma in situ (LCIS. Genome-wide association studies have identified more than 70 common polymorphisms that predispose to breast cancer, but these studies included predominantly ductal (IDC carcinomas. To identify novel common polymorphisms that predispose to ILC and LCIS, we pooled data from 6,023 cases (5,622 ILC, 401 pure LCIS and 34,271 controls from 36 studies genotyped using the iCOGS chip. Six novel SNPs most strongly associated with ILC/LCIS in the pooled analysis were genotyped in a further 516 lobular cases (482 ILC, 36 LCIS and 1,467 controls. These analyses identified a lobular-specific SNP at 7q34 (rs11977670, OR (95%CI for ILC = 1.13 (1.09-1.18, P = 6.0 × 10(-10; P-het for ILC vs IDC ER+ tumors = 1.8 × 10(-4. Of the 75 known breast cancer polymorphisms that were genotyped, 56 were associated with ILC and 15 with LCIS at P<0.05. Two SNPs showed significantly stronger associations for ILC than LCIS (rs2981579/10q26/FGFR2, P-het = 0.04 and rs889312/5q11/MAP3K1, P-het = 0.03; and two showed stronger associations for LCIS than ILC (rs6678914/1q32/LGR6, P-het = 0.001 and rs1752911/6q14, P-het = 0.04. In addition, seven of the 75 known loci showed significant differences between ER+ tumors with IDC and ILC histology, three of these showing stronger associations for ILC (rs11249433/1p11, rs2981579/10q26/FGFR2 and rs10995190/10q21/ZNF365 and four associated only with IDC (5p12/rs10941679; rs2588809/14q24/RAD51L1, rs6472903/8q21 and rs1550623/2q31/CDCA7. In conclusion, we have identified one novel lobular breast cancer specific predisposition polymorphism at 7q34, and shown for the first time that common breast cancer polymorphisms predispose to LCIS. We have shown that many of the ER+ breast cancer predisposition loci also predispose to ILC, although there is some heterogeneity

    Full Text Available The prevalence of ductal carcinoma in situ (DCIS of the breast has increased substantially after the introduction of breast cancer screening programs, although the clinical effects of early DCIS detection and treatment remain unclear. The standard treatment for DCIS has involved local breast-conserving surgery (BCS followed by radiotherapy (RT or total mastectomy with/without endocrine therapy, and the choice of local treatment is not usually based on clinicopathologic or biological factors. However, we have investigated the effectiveness of local treatment using breast surgery and RT using Surveillance, Epidemiology, and End Results data, and found that the effectiveness of breast surgery was modified by the nuclear grade. Furthermore, breast cancer-specific survival was identical between patients with low-grade DCIS who did and did not undergo surgery. Moreover, we found that RT after BCS for DCIS was only associated with a survival benefit among patients with risk factors for local recurrence, such as nuclear grade, age, and tumor size. Ongoing clinical trials and translational research have attempted to develop a treatment strategy that prevents the overdiagnosis and overtreatment of low-risk DCIS, as well as a biology-based treatment strategy for using targeted therapy. Therefore, to develop a tailored treatment strategy for DCIS, we need to identify molecular and biological classifications based on the results from translational research, national databases, and clinical trials.

    Breast cancer (BC) shows very high incidence rates in Uruguayan women. The present factor analysis of ductal carcinoma of the breast, the most frequent histological type of this malignancy both in Uruguay and in the World, was conducted at a prepaid hospital of Montevideo, Uruguay. We identified 111 cases with ductal BC and 222 controls with normal mammograms. A factor analysis was conducted using 39 food groups, allowing retention of six factors analyzed through logistic regression in order to obtain odds ratios (OR) associated with ductal BC. The low fat and non-alcoholic beverage patterns were inversely associated (OR=0.30 and OR=0.45, respectively) with risk. Conversely, the fatty cheese pattern was positively associated (OR=4.17) as well as the fried white meat (OR=2.28) and Western patterns (OR 2.13). Ductal BC shared similar dietary risk patterns as those identified by studies not discriminating between histologic type of breast cancer.

    A 70-year-old female patient with prior breast cancer was diagnosed with colorectal carcinoma six years following the original breast referral. The cancers were both discovered at an early stage enabling potentially curative surgery to be performed, with an associated good long-term prognosis. This article explores a range of cancer risk factors associated with lifestyle, genetics and medication to ascertain whether the two primary cancers were independent oncological events, or whether they were related. Factors such as smoking, alcohol consumption, genetic predisposition and the use of contraceptives and Tamoxifen may increase the relative risk for both cancers. Various studies have offered conflicting data regarding the relative risk for developing the second cancer, but long-term cohort studies will continue to add to the evidence base. It is possible that the outcomes of these studies may have implications for the follow up of breast cancer patients within the colorectal cancer screening service.

    Full Text Available Abstract Background Recent studies suggest an association between chronic inflammation, modulating the tissue microenvironment, and tumor biology. Tumor environment consists of tumor, stromal and endothelial cells and infiltrating macrophages, T lymphocytes, and dendritic cells, producing an array of cytokines, chemokines and growth factors, accounting for a complex cell interaction and regulation of differentiation, activation, function and survival of tumor and surrounding cells, responsible for tumor progression and spreading or induction of antitumor immune responses and rejection. Tumor Necrosis Factor (TNF family members (19 ligands and 29 receptors represent a pleiotropic family of agents, related to a plethora of cellular events from proliferation and differentiation to apoptosis and tumor reduction. Among these members, BAFF and APRIL (CD257 and CD256 respectively gained an increased interest, in view of their role in cell protection, differentiation and growth, in a number of lymphocyte, epithelial and mesenchymal structures. Methods We have assayed by immunohistochemistry 52 human breast cancer biopsies for the expression of BAFF and APRIL and correlated our findings with clinicopathological data and the evolution of the disease. Results BAFF was ubiquitely expressed in breast carcinoma cells, DCIS, normal-appearing glands and ducts and peritumoral adipocytes. In contrast, APRIL immunoreactive expression was higher in non-malignant as compared to malignant breast structures. APRIL but not BAFF immunoreactivity was higher in N+ tumors, and was inversely related with the grade of the tumors. Neither parameter was related to DFS or the OS of patients. Conclusion Our data show, for the first time, an autocrine secretion of BAFF and APRIL from breast cancer cells, offering new perspectives for their role in neoplastic and normal breast cell biology and offering new perspectives for possible selective intervention in breast cancer.

We hypothesize that activation of the SHH pathway contributes to the recurrence of breast carcinoma.Methods: Fifty consecutive patients with invasive breast carcinoma following curative resection were enrolled in this prospective study. The ratios of messenger RNA (mRNA expression for Sonic Hedgehog (SHH, patched homolog-1 (PTCH-1, glioma-associated oncogene-1 (GLI-1, and smoothened (SMOH were measured between breast carcinoma tissue and paired noncancerous breast tissue. These ratios were compared with their clinicopathologic characteristics. These factors and the mRNA ratios were compared between patients with recurrence and those without recurrence.Results: The size of the invasive cancer correlated significantly with the ratio of SHH mRNA (P=0.001, that of PTCH-1 mRNA (P=0.005, and that of SMOH mRNA (P=0.021. Lymph node involvement correlated significantly with the ratio of SMOH mRNA (P=0.041. The correlation between Her-2 neu and the ratio of GLI-1 mRNA was statistically significant (P=0.012. Each ratio of mRNA of SHH, PTCH-1, GLI-1, and SMOH correlated significantly with cancer recurrence (P<0.001 for each.Conclusion: We suggest that high expression of SHH mRNA, PTCH-1 mRNA, GLI-1 mRNA, and SMOH mRNA in breast cancer tissue correlates with invasiveness and is a potential biomarker to predict postoperative recurrence.Keywords: SHH pathway, breast carcinoma, prediction, recurrence

    From 1981 to 1988, 265 patients with breast cancer stages I and II (UICC-1987), were evaluated after conservative treatment with quadrantectomy plus axillectomy, radiotherapy and chemotherapy. After surgical treatment, the patients were submitted to radiation therapy in the breast. One hundred and fifty six (58,8%) patients were submitted to adjuvant chemotherapy. The median clinical follow-up period was 42.8 months with a minimum of 24 and a maximum of 99 months. Six (2,3%) patients presented local recurrence and 48 (18,1%) presented distant metastasis. After five years the total survival rate was 89,7% and the disease free survival rate was 75% in the same period. The study did not show significant differences among the clinical stages classified after surgery and the use of adjuvant chemotherapy did not influence the results of the many stages.

    Purpose: The optimal management of breast cancer in elderly women is not well established. Therefore, the present study was undertaken to evaluate the outcome of breast cancer in elderly women treated with breast-conserving surgery and definitive breast irradiation. Methods and Materials: An analysis was performed of 558 women age ≥ 50 years treated with breast-conserving surgery and definitive breast irradiation for Stages I-II invasive carcinoma of the breast. Of the 558 total women, there were 173 elderly women age ≥ 65 years and a comparison group of 385 women age 50-64 years. Treatment for all women included complete gross excision of the primary tumor, pathologic axillary lymph node staging, and definitive breast irradiation. Adjuvant systemic chemotherapy was used in 18% (102 out of 558) of the overall group. Adjuvant tamoxifen was used in 17% (94 out of 558) of the overall group. The median follow-up after treatment was 6.2 years (mean = 6.4 years; range 0.1-15.4 years). Results: Elderly patients age ≥ 65 years and patients age 50-64 years were both found to have tumors with adverse prognostic features, including clinical T2 lesions (43 vs. 34%, respectively; p = 0.055), estrogen receptor negativity (9 vs. 16%, respectively; p = 0.13), and progesterone receptor negativity (17 vs. 21%, respectively; p = 0.50). Pathologic axillary lymph node staging showed that 24% of the elderly women were node positive, including 8% with four or more positive nodes, which was not different from women age 50-64 years (p = 0.23). There was no difference between the two age groups for the rate of deaths from breast cancer at 10 years (13 vs. 13%, respectively; p = 0.71). However, there was a significant difference between the two age groups for the rate of deaths from intercurrent disease at 10 years (11 vs. 2%, respectively; p = 0.0006). There were no differences between the two age groups for the 10-year rates of overall survival (77 vs. 85%, respectively; p = 0

    One hundred patients with operable breast cancer received 'prophylactic' postoperative irradiation after mastectomy. In addition, during irradiation and for four months afterwards, part of the patients received immunotherapy (BCG scarification and oral administration of levamisole), while the rest served as controls. Although survival time in the two groups was about the same, disease-free survival time was significantly longer in the immunotherapy group. Tumor reactivation was preceded by deterioration of the Leucocyte Migration Inhibition Index.

  11. The Reproducibility of Nuclear Morphometric Measurements in Invasive Breast Carcinoma

    Full Text Available The intraobserver and interobserver reproducibility of computerized nuclear morphometry was determined in repeated measurements of 212 samples of invasive breast cancer. The influence of biological variation and the selection of the measurement area was also tested. Morphometrically determined mean nuclear profile area (Pearson’s r 0.89, grading efficiency (GE 0.95 and standard deviation (SD of nuclear profile area (Pearson’s r 0.84, GE 0.89 showed high reproducibility. In this respect, nuclear morphometry equals with other established methods of quantitative pathology and exceeds the results of subjective grading of nuclear atypia in invasive breast cancer. A training period of eight days was sufficient to produce clear improvement in consistency of nuclear morphometry results. By estimating the sources of variation it could be shown that the variation associated with the measurement procedure itself is small. Instead, sample associated variation is responsible for the majority of variation in the measurements (82.9% in mean nuclear profile area and 65.9% in SD of nuclear profile area. This study points out that when standardized methods are applied computerized morphometry is a reproducible and reliable method of assessing nuclear atypia in invasive breast cancer. For further improvement special emphasize should be put on sampling rules of selecting the microscope fields and measurement areas.

  12. The Expression of the Zonula Adhaerens Protein PLEKHA7 Is Strongly Decreased in High Grade Ductal and Lobular Breast Carcinomas.

    Directory of Open Access Journals (Sweden)

    Full Text Available PLEKHA7 is a junctional protein, which participates in a complex that stabilizes E-cadherin at the zonula adhaerens. Since E-cadherin is involved in epithelial morphogenesis, signaling, and tumor progression, we explored PLEKHA7 expression in cancer. PLEKHA7 expression was assessed in invasive ductal and lobular carcinomas of the breast by immunohistochemistry, immunofluorescence and quantitative RT-PCR. PLEKHA7 was detected at epithelial junctions of normal mammary ducts and lobules, and of tubular and micropapillary structures within G1 and G2 ductal carcinomas. At these junctions, the localization of PLEKHA7 was along the circumferential belt (zonula adhaerens, and only partially overlapping with that of E-cadherin, p120ctn and ZO-1, as shown previously in rodent tissues. PLEKHA7 immunolabeling was strongly decreased in G3 ductal carcinomas and undetectable in lobular carcinomas. PLEKHA7 mRNA was detected in both ductal and lobular carcinomas, with no observed correlation between mRNA levels and tumor type or grade. In summary, PLEKHA7 is a junctional marker of epithelial cells within tubular structures both in normal breast tissue and ductal carcinomas, and since PLEKHA7 protein but not mRNA expression is strongly decreased or lost in high grade ductal carcinomas and in lobular carcinomas, loss of PLEKHA7 is a newly characterized feature of these carcinomas.

    Invasive micropapillary serous carcinoma (MPSC) also designated "low-grade serous carcinoma" (LGSC) of the ovary is characterized by small micropapillae that infiltrate underlying tissue (ovarian stroma). On occasion these tumors in addition to the micropapillae contain large macropapillae lined by bland epithelium. In rare cases, the entire tumor is composed of macropapillae. In these cases, the question of whether this is an invasive carcinoma or an unusual type of adenofibroma has been raised. The goal of this study was to describe this unusual macropapillary pattern of invasion in LGSC. Cases of LGSC containing macropapillae were retrieved from the files of the Johns Hopkins Hospital. In addition to a detailed morphologic analysis, the mutational status of KRAS and BRAF in the macropapillary, noninvasive, and invasive MPSC components was analyzed by nucleotide sequencing. There were 14 cases containing macropapillae (11 cases of LGSC, 2 cases of atypical proliferative serous tumor (APST) with microinvasion, and 1 case of APST with a focus of LGSC with macropapillae in perivaginal soft tissue). In 3 cases, extraovarian metastases contained macropapillae. Molecular analysis of the primary tumor components (macropapillary, noninvasive, and invasive MPSC and/or APST) was performed in 7 cases and of a lymph node metastasis with macropapillae in 1 case. The identical KRAS mutation was detected in all of the analyzed components of the primary ovarian tumors in 4 cases. In one of these cases, macropapillae in the lymph node metastasis contained a KRAS mutation identical to the primary tumor. The BRAF mutation identified in 1 case was identical in all components of the ovarian tumor. The identical mutations in the macropapillae and the other tumor components in each case indicate that they are clonally related. The finding of macropapillae within lymph nodes supports the interpretation that the macropapillary component is another manifestation of invasion in LGSC. The

    Improving technologies for the detection and purification of bone marrow (BM) micrometastatic cells in breast cancer patients should lead to earlier prognosis of the risk of relapse and should make it possible to design more appropriate therapies. The technique used has to overcome the challenges resulting from the small number of target cells (one per million hematopoietic cells) and the heterogeneous expression of micrometastatic cell markers. In the present study, we have assessed the clinical relevance of current methods aimed at detecting rare disseminated carcinoma cells. BM aspirates from 32 carcinoma patients were screened for the presence of micrometastatic cells positive for epithelial cell adhesion molecule and positive for cytokeratins, using optimized immunodetection methods. A comparison with data obtained for 46 control BM aspirates and a correlation with the clinical status of patients were performed. We developed a sensitive and efficient immunomagnetic protocol for the enrichment of BM micrometastases. This method was used to divide 32 breast carcinoma patients into three categories according to their epithelial cell adhesion molecule status. These categories were highly correlated with the recently revised American Joint Committee on Cancer staging system for breast cancer, demonstrating the clinical relevance of this simple and reliable immunomagnetic technique. We also evaluated immunocytochemical detection of cytokeratin-positive cells and cytomorphological parameters. Immunocytochemistry-based methods for the detection of BM micrometastases did not provide any information about the clinical status of patients, but helped to refine the immunomagnetic data by confirming the presence of micrometastases in some cases. We also tested a new density gradient centrifugation system, able to enrich the tumor fraction of BM specimens by twofold to threefold as compared with standard Ficoll methods. These improved methods for the detection of

    To fully elucidate the clinicopathological features of breast carcinoma in sclerosing adenosis (SA-BC). Clinical and histological characteristics of 206 SA-BCs from 180 patients were retrospectively evaluated. Immunohistochemical phenotype was examined. The clinicopathological relevance of the topographical pattern of SA-BCs was analysed. Overall, up to 46 patients (25.6%) had contralateral cancer, either SA associated or not. Of 99 cases who underwent core needle biopsy (CNB), 36 were underestimated as adenosis or atypical ductal hyperplasia at CNB, 5 invasive cases were misinterpreted as in situ carcinomas, whereas 4 ductal carcinoma in situ (DCIS) cases were overdiagnosed as invasive carcinoma. Microscopically, 163 tumours were in situ, including 136 DCIS, 19 lobular carcinomas in situ (LCIS) and 8 mixed DCIS/LCIS; of these carcinomas in situ (CIS), 37 had microinvasion. The DCIS group exhibited low, intermediate and high grades in 53.7%, 34.6% and 11.8% of cases, respectively, mostly with solid (43.4%) or cribriform (41.9%) pattern. Forty out of 43 invasive cases were invasive ductal carcinoma (IDC), mostly DCIS predominant. Immunophenotypically, luminal A phenotype was identified in 55.1%, 63.2% and 45.0% of DCIS, LCIS and IDC cases, respectively. Topographical type A group (carcinoma being entirely confined to SA, n=176) was characterised by smaller size, less invasiveness, lower grade and more frequency of luminal A immunophenotype compared with type B group (≥ 50% but not all of the carcinomatous lesion being located in SA, n=30) (all P<0.05). CIS, especially non-high-grade DCIS, represents the most common variant of SA-BC, and luminal A is the most predominant immunophenotype. CNB assessment might be challenging in some SA-BCs. The topographical pattern has great clinicopathological relevance. Careful evaluation of the contralateral breast and long-term follow-up for patients with SA-BC is necessary given its high prevalence of bilaterality. © Article

    Tumor-infiltrating lymphocytes and immune checkpoint proteins such as PD-L1 are potential prognostic factors and therapeutic targets in breast cancer. Most studies characterizing the breast tumor immune microenvironment have focused on ductal carcinomas. Here we investigate the tumor microenvironment of primary invasive lobular carcinomas. Previously constructed tissue microarrays of 47 lobular carcinomas were labeled by immunohistochemistry for PD-L1, CD8, CD20, and FoxP3. The stromal immune infiltrate density was qualitatively scored as a percentage of tumor area: 1+ (50%). The average immune cell subtype per high-power field was quantitatively scored. The percentage PD-L1 labeling on tumor-infiltrating lymphocytes was scored as none, focal (lobular carcinomas contained PD-L1 + tumor-infiltrating lymphocytes with the majority showing 1+ immune infiltrates with focal-moderate PD-L1 labeling. PD-L1 was expressed by tumor cells in 17% of lobular carcinomas. In contrast to ductal carcinomas, there was no correlation between the immune infiltrate density, the PD-L1 expression by lobular carcinoma cells, tumor grade, or the expression of estrogen receptor or human epidermal growth factor receptor-2. However, both the tumor-infiltrating lymphocyte density and the average CD8 + T-cell counts correlated with immune cell PD-L1 status (P=0.004 and 0.03, respectively). Similar to breast ductal carcinomas, PD-L1 + lobular breast carcinomas had higher numbers of PD-L1 + tumor-infiltrating lymphocytes (63%) than PD-L1 - lobular carcinomas (23%; P=0.04). These data show that a subset of primary breast lobular carcinomas both express PD-L1 on tumor cells and contain PD-L1 + tumor-infiltrating lymphocytes, suggesting the possibility of both constitutive and adaptive PD-L1 expression. Together, these results support immunotherapy as a potential treatment for a subset of patients with primary invasive lobular breast carcinomas.

    This work presents experimental and analytical comparison of terahertz transmission and reflection imaging modes for assessing breast carcinoma in excised paraffin-embedded human breast tissue. Modeling for both transmission and reflection imaging is developed. The refractive index and absorption coefficient of the tissue samples are obtained. The reflection measurements taken at the system's fixed oblique angle of 30° are shown to be a hybridization of TE and TM modes. The models are validated with transmission spectroscopy at fixed points on fresh bovine muscle and fat tissues. Images based on the calculated absorption coefficient and index of refraction of bovine tissue are successfully compared with the terahertz magnitude and phase measured in the reflection mode. The validated techniques are extended to 20 and 30 μm slices of fixed human lobular carcinoma and infiltrating ductal carcinoma mounted on polystyrene microscope slides in order to investigate the terahertz differentiation of the carcinoma with non-cancerous tissue. Both transmission and reflection imaging show clear differentiation in carcinoma versus healthy tissue. However, when using the reflection mode, in the calculation of the thin tissue properties, the absorption is shown to be sensitive to small phase variations that arise due to deviations in slide and tissue thickness and non-ideal tissue adhesion. On the other hand, the results show that the transmission mode is much less sensitive to these phase variations. The results also demonstrate that reflection imaging provides higher resolution and more clear margins between cancerous and fibroglandular regions, cancerous and fatty regions, and fibroglandular and fatty tissue regions. In addition, more features consistent with high power pathology images are exhibited in the reflection mode images.

    Breast cancer is the second leading cause of cancer death among women. Its early diagnosis is extremely important to prevent avoidable deaths. However, malignancy assessment of tissue biopsies is complex and dependent on observer subjectivity. Moreover, hematoxylin and eosin (H&E)-stained histological images exhibit a highly variable appearance, even within the same malignancy level. In this paper, we propose a computer-aided diagnosis (CAD) tool for automated malignancy assessment of breast tissue samples based on the processing of histological images. We provide four malignancy levels as the output of the system: normal, benign, in situ and invasive. The method is based on the calculation of three sets of features related to nuclei, colour regions and textures considering local characteristics and global image properties. By taking advantage of well-established image processing techniques, we build a feature vector for each image that serves as an input to an SVM (Support Vector Machine) classifier with a quadratic kernel. The method has been rigorously evaluated, first with a 5-fold cross-validation within an initial set of 120 images, second with an external set of 30 different images and third with images with artefacts included. Accuracy levels range from 75.8% when the 5-fold cross-validation was performed to 75% with the external set of new images and 61.11% when the extremely difficult images were added to the classification experiment. The experimental results indicate that the proposed method is capable of distinguishing between four malignancy levels with high accuracy. Our results are close to those obtained with recent deep learning-based methods. Moreover, it performs better than other state-of-the-art methods based on feature extraction, and it can help improve the CAD of breast cancer. Copyright © 2018 Elsevier Ltd. All rights reserved.

The anti-cancer mechanism of IDOE remains unclear. This study aims to investigate the antiproliferative activity of IDOE on breast carcinoma T47D cells and lung carcinoma A549 cells. The growth inhibitory effects of IDOE on breast carcinoma T47D cells, lung carcinoma A549 cells, and normal lymphocytes were evaluated by the MTT assay. Morphological analysis of apoptosis induction was performed by acridine orange/ethidium bromide dual-staining and Hoechst 33342 nuclear staining. The cell cycle profile, caspase-3 expression, and annexin V staining were evaluated by flow cytometry. IDOE inhibited the growth of A549 and T47D cells in a dose- and time-dependent manner with IC50 values of 10.46 and 1.3 μg/mL, respectively. IDOE was not significantly toxic to normal lymphocytes. The cells became detached from the monolayer and rounded up, had fragmented nuclei and condensed chromatin, and the numbers of apoptotic cells increased (P = 0.0003). IDOE-induced cell death was associated with activated caspase-3 expression followed by cell cycle arrest at G2/M phase. IDOE inhibited the proliferation of breast cancer cells and lung carcinoma cells and induced caspase-3-mediated apoptosis and cell cycle arrest in the treated cells.

    Metaplastic breast carcinoma (MBC) is a rare malignancy comprised of ductal, squamous and/or mesenchymal elements with problematic diagnosis. This study analyses MBC identifying its cytologic and histologic features and emphasizing the combined role of FNAC, histopathology and immunohistochemistry (IHC) in its diagnosis. Cytology and histopathology files search yielded 21 cases identified as MBC from January 2005 to December 2010. FNAC and the histopathology slides were re-examined for the presence and frequency of various elements. Cytological and histopathological diagnoses were made and the cases subtyped according to WHO classification. Cytokeratin and vimenten IHC were used to confirm diagnosis when required. On FNAC, 52.4% were diagnosed as malignant, 9.5% as suspicious for malignancy and 38.1% as benign lesions. Most frequent cytologic findings were squamous and spindle cell elements (52.4% each). Histopathology revealed 76.2% pure epithelial tumors and 23.8% mixed epithelial-mesenchymal tumors. Squamous cell carcinoma was the most frequent histological subtype (33.3%). Carcinosarcomas were dimorphic on IHC& spindle cell carcinomas were positive for both cytokeratin and vimentin. Presence of dual components, squamous, spindle elements, mesenchymal fragments and necrosis in moderate to high cellularity breast FNAC provides clues for the diagnosis of MBC.

    Full Text Available Breast cancer is the leading cause of cancer death in women and the second most common cancer worldwide after lung cancer. The remarkable heterogeneity of breast cancers influences numerous diagnostic, therapeutic and prognostic factors. Triple-negative breast cancers (TNBCs lack expression of HER2 and the estrogen and progesterone receptors and often contain lymphocytic infiltrates. Most of TNBCs are invasive ductal carcinomas (IDCs with poor prognosis, whereas prognostically more favorable subtypes such as medullary breast carcinomas (MBCs are somewhat less frequent. Infiltrating T cells have been associated with an improved clinical outcome in TNBCs. The prognostic role of γδ T cells within CD3+ tumor-infiltrating T lymphocytes remains unclear. We analyzed 26 TNBCs, 14 IDCs and 12 MBCs, using immunohistochemistry for the quantity and patterns of γδ T-cell infitrates within the tumor microenvironment. In both types of TNBCs, we found higher numbers of γδ T cells in comparison with normal breast tissues and fibroadenomas. The numbers of infiltrating γδ T cells were higher in MBCs than in IDCs. γδ T cells in MBCs were frequently located in direct contact with tumor cells, within the tumor and at its invasive border. In contrast, most γδ T cells in IDCs were found in clusters within the tumor stroma. These findings could be associated with the fact that the patient’s prognosis in MBCs is better than that in IDCs. Further studies to characterize these γδ T cells at the molecular and functional level are in progress.

    Invasive ductal carcinoma (IDC) with lobular features (IDC-L) is not recognized as a subtype of breast cancer. We previously showed that IDC-L may be a variant of IDC with clinicopathological characteristics more similar to invasive lobular carcinoma (ILC). We sought to determine the re-excision rates of IDC-L compared with ILC and IDC, and the feasibility of diagnosing IDC-L on core biopsies. Surgical procedure, multiple tumor foci, tumor size, and residual invasive carcinoma on re-excision were recorded for IDC-L (n = 178), IDC (n = 636), and ILC (n = 251). Re-excision rates were calculated by excluding mastectomy as first procedure cases and including only re-excisions for invasive carcinoma. Slides of correlating core biopsies for IDC-L cases initially diagnosed as IDC were re-reviewed. For T2 tumors (2.1-5.0 cm), re-excision rates for IDC-L (76 %) and ILC (88 %) were higher than that for IDC (42 %) (p = 0.003). Multiple tumor foci were more common in IDC-L (31 %) and ILC (26 %) than IDC (7 %) (p < 0.0001), which was a significant factor in higher re-excision rates when compared with a single tumor focus (p < 0.001). Ninety-two of 149 patients (62 %) with IDC-L were diagnosed on core biopsies. Of the 44 patients initially diagnosed as IDC, 30 were re-reviewed, of which 24 (80 %) were re-classified as IDC-L. Similar to ILC, re-excision rates for IDC-L are higher than IDC for larger tumors. Patients may need to be counseled about the higher likelihood of additional procedures to achieve negative margins. This underscores the importance of distinguishing IDC-L from IDC on core biopsies.

    The importance of microenvironment and context in regulation of tissue-specific genes is finally well established. DNA exposure to, or sequestration from, nucleases can be used to detect differences in higher order chromatin structure in intact cells without disturbing cellular or tissue architecture. To investigate the relationship between chromatin organization and tumor phenotype, we utilized an established 3-D assay where normal and malignant human breast cells can be easily distinguished by the morphology of the structures they make (acinus-like vs tumor-like, respectively). We show that these phenotypes can be distinguished also by sensitivity to AluI digestion where the malignant cells are resistant to digestion relative to non-malignant cells. Reversion of the T4-2 breast cancer cells by either cAMP analogs, or a phospatidylinositol 3-kinase (P13K) inhibitor not only reverted the phenotype, but also the chromatin sensitivity to AluI. By using different cAMP-analogs, we show that the cAMP-induced phenotypic reversion, polarization, and shift in DNA organization act through a cAMP-dependent-protein-kinase A-coupled signaling pathway. Importantly, inhibitory antibody to fibronectin also reverted the malignant phenotype, polarized the acini, and changed chromatin sequestration. These experiments show not only that modifying the tumor microenvironment can alter the organization of tumor cells but also that architecture of the tissues and the global chromatin organization are coupled and yet highly plastic.

    The application of magnetic fluid hyperthermia (MFH) with nanoparticles has been shown to inhibit tumor growth in several animal models. However, the feasibility of using MFH in vivo to treat breast cancer is uncertain, and the mechanism is unclear. In the present study, it was observed that the intratumoral administration of MFH induced hyperthermia significantly in rats with Walker-265 breast carcinomas. The hyperthermia treatment with magnetic nanoparticles inhibited tumor growth in vivo and promoted the survival of the tumor-bearing rats. Furthermore, it was found that MFH treatment downregulated the protein expression of vascular endothelial growth factor (VEGF) in the tumor tissue, as observed by immunohistochemistry. MFH treatment also decreased the gene expression of VEGF and its receptors, VEGF receptor 1 and 2, and inhibited angiogenesis in the tumor tissues. Taken together, these results indicate that the application of MFH with nanoparticles is feasible for the treatment of breast carcinoma. The MFH-induced downregulation of angiogenesis may also contribute to the induction of an anti-tumor effect. PMID:24765139

    Purpose: The results of breast-conservation therapy using breast irradiation and a boost to the tumor excision site with either electron beam or interstitial 192 Ir implant are reviewed. Methods and Materials: A total of 701 patients with histologically confirmed Stage T1 and T2 carcinoma of the breast were treated with wide local tumor excision or quadrantectomy and breast irradiation. The breast was treated with tangential fields using 4 or 6 MV photons to deliver 48 to 50 Gy in 1.8 to 2 Gy daily dose, in five weekly fractions. In 80 patients the regional lymphatics were irradiated. In 342 patients with Stage T1 and 107 with Stage T2 tumors, boost to the primary tumor excision site was delivered with 9 MeV and, more frequently, with 12 MeV electrons. In 91 patients with Stage T1 and 38 patients with Stage T2 tumors an interstitial 192 Ir implant was performed. Tumor control, disease-free survival, cosmesis, and morbidity of therapy are reviewed. Minimum follow-up is 4 years (median, 5.6 years; maximum, 24 years). Results: The overall local tumor recurrence rates were 5% in the T1 and 11% in the T2 tumor groups. There was no significant difference in the breast relapse rate in patients treated with either electron beam or interstitial 192 Ir boost. Regional lymph node recurrences were 1% in patients with T1 and 5% with T2 tumors. Distant metastases were recorded in 5% of the T1 and 23% of the T2 groups. The 10-year actuarial disease-free survival rates were 87% for patients with T1 and 75% for patients with T2 tumors. Disease-free survival was exactly the same in patients receiving either electron beam or interstitial 192 Ir boost. Cosmesis was rated as excellent/good in 84% of patients with T1 tumors treated with electron beam and 81% of patients treated with interstitial implant, and 74 and 79%, respectively, in patients with T2 tumors. Conclusions: Breast-conservation therapy is an effective treatment for patients with T1 and T2 carcinoma of the breast. There

    Cyclooxygenase-2 (COX-2) overexpression is implicated in increased risk and poorer outcomes in breast cancer in young women. We investigated COX-2 regulation in normal premenopausal breast tissue and its relationship to malignancy in young women. Quantitative COX-2 immunohistochemistry was performed on adjacent normal and breast cancer tissues from 96 premenopausal women with known clinical reproductive histories, and on rat mammary glands with distinct ovarian hormone exposures. COX-2 expression in the normal breast epithelium varied more than 40-fold between women and was associated with COX-2 expression levels in ductal carcinoma in situ and invasive cancer. Normal breast COX-2 expression was independent of known breast cancer prognostic indicators, including tumor stage and clinical subtype, indicating that factors regulating physiological COX-2 expression may be the primary drivers of COX-2 expression in breast cancer. Ovarian hormones, particularly at pregnancy levels, were identified as modulators of COX-2 in normal mammary epithelium. However, serial breast biopsy analysis in nonpregnant premenopausal women suggested relatively stable baseline levels of COX-2 expression, which persisted independent of menstrual cycling. These data provide impetus to investigate how baseline COX-2 expression is regulated in premenopausal breast tissue because COX-2 levels in normal breast epithelium may prove to be an indicator of breast cancer risk in young women, and predict the chemopreventive and therapeutic efficacy of COX-2 inhibitors in this population.

    Background: Mammary adenoid cystic carcinoma (ACC) is a rare breast cancer. The aim of this retrospective study was to assess prognostic factors and patterns of failure, as well as the role of radiation therapy (RT), in ACC. Methods: Between January 1980 and December 2007, 61 women with breast ACC were treated at participating centers of the Rare Cancer Network. Surgery consisted of lumpectomy in 41 patients and mastectomy in 20 patients. There were 51(84%) stage pN0 and 10 stage cN0 (16%) patients. Postoperative RT was administered to 40 patients (35 after lumpectomy, 5 after mastectomy). Results: With a median follow-up of 79 months (range, 6–285), 5-year overall and disease-free survival rates were 94% (95% confidence interval [CI], 88%–100%) and 82% (95% CI, 71%–93%), respectively. The 5-year locoregional control (LRC) rate was 95% (95% CI, 89%–100%). Axillary lymph node dissection or sentinel node biopsy was performed in 84% of cases. All patients had stage pN0 disease. In univariate analysis, survival was not influenced by the type of surgery or the use of postoperative RT. The 5-year LRC rate was 100% in the mastectomy group versus 93% (95% CI, 83%–100%) in the breast-conserving surgery group, respectively (p = 0.16). For the breast-conserving surgery group, the use of RT significantly correlated with LRC (p = 0.03); the 5-year LRC rates were 95% (95% CI, 86%–100%) for the RT group versus 83% (95% CI, 54%–100%) for the group receiving no RT. No local failures occurred in patients with positive margins, all of whom received postoperative RT. Conclusion: Breast-conserving surgery is the treatment of choice for patients with ACC breast cancer. Axillary lymph node dissection or sentinel node biopsy might not be recommended. Postoperative RT should be proposed in the case of breast-conserving surgery.

    Purpose: To determine outcomes of accelerated partial-breast irradiation (APBI) with MammoSite in the treatment of ductal carcinoma in situ (DCIS) after breast-conserving surgery. Methods and Materials: We conducted a prospective, multicenter trial between 2003 and 2009. Inclusion criteria included age >18 years, core needle biopsy diagnosis of DCIS, and no prior breast cancer history. Patients underwent breast-conserving surgery plus MammoSite placement. Radiation was given twice daily for 5 days for a total of 34 Gy. Patients were evaluated for development of toxicities, cosmetic outcome, and ipsilateral breast tumor recurrence (IBTR). Results: A total of 41 patients (42 breasts) completed treatment in the study, with a median follow up of 5.3 years. Overall, 28 patients (68.3%) experienced an adverse event. Skin changes and pain were the most common adverse events. Cosmetic outcome at 6 months was judged excellent/good by 100% of physicians and by 96.8% of patients. At 12 months, 86.7% of physicians and 92.3% of patients rated the cosmetic outcome as excellent/good. Overall, 4 patients (9.8%) developed an IBTR (all DCIS), with a 5-year actuarial rate of 11.3%. All IBTRs were outside the treatment field. Among patients with IBTRs, the mean time to recurrence was 3.2 years. Conclusions: Accelerated partial-breast irradiation using MammoSite seems to provide a safe and cosmetically acceptable outcome; however, the 9.8% IBTR rate with median follow-up of 5.3 years is concerning. Prospective randomized trials are necessary before routine use of APBI for DCIS can be recommended.

    The SRY-related HMG-box family of transcription factors member SOX2 has been mainly studied in embryonic stem cells as well as early foregut and neural development. More recently, SOX2 was shown to participate in reprogramming of adult somatic cells to a pluripotent stem cell state and implicated in tumorigenesis in various organs. In breast cancer, SOX2 expression was reported as a feature of basal-like tumors. In this study, we assessed SOX2 expression in 95 primary tumors of postmenopausal breast cancer patients. Samples from 95 patients diagnosed and treated at the University of Tuebingen Institute of Pathology and Women's Hospital were analyzed by immunohistochemistry for SOX2 expression in the primary tumor samples and in corresponding lymph node metastasis, where present. Furthermore, SOX2 amplification status was assessed by FISH in representative samples. In addition, eighteen fresh frozen samples were analyzed for SOX2, NANOG and OCT4 gene expression by real-time PCR. SOX2 expression was detected in 28% of invasive breast carcinoma as well as in 44% of ductal carcinoma in situ (DCIS) lesions. A score of SOX2 expression (score 0 to 3) was defined in order to distinguish SOX2 negative (score 0) from SOX2 positive samples (score 1-3) and among latter the subgroup of SOX2 high expressors (score 3 > 50% positive cells). Overall, the incidence of SOX2 expression (score 1-3) was higher than previously reported in a cohort of lymph node negative patients (28% versus 16.7%). SOX2 expression was detected across different breast cancer subtypes and did not correlate with tumor grading. However, high SOX2 expression (score 3) was associated with larger tumor size (p = 0.047) and positive lymph node status (0.018). Corresponding metastatic lymph nodes showed higher SOX2 expression and were significantly more often SOX2 positive than primary tumors (p = 0.0432). In this report, we show that the embryonic stem cell factor SOX2 is expressed in a variety of early

    Full Text Available Invasive lobular breast carcinoma is the second most common type of breast cancer after invasive ductal carcinoma. According to the American Cancer Society, more than 180,000 women in the United States find out they have invasive breast cancer each year. Personal history of breast cancer and certain changes in the breast are correlated with an increased breast cancer risk. The aim of this work was to analyze breastfeeding in patients with infiltrating lobular breast carcinoma, in relation with: 1 clinicopathological parameters, 2 hormonal receptors and 3 tissue-based tumor markers.The study included 80 women with ILC, 46 of which had breastfeed their children. Analyzed parameters were: age, tumor size, axillary lymph node (N, distant metastasis (M, histological grade (HG, estrogen receptor (ER, progesterone receptor (PR, androgen receptor (AR, Ki-67, p53 and BCL2.ILC of non-lactating women showed a larger (p = 0.009, lymph node involvement (p = 0.051 and distant metastasis (p = 0.060. They were also more proliferative tumors measured by Ki-67 (p = 0.053. Breastfeeding history did not influence the subsequent behavior of the tumor regardless of histological subtype.Lactation seems to influence the biological characteristics of ILC defining a subgroup with more tumor size, axillary lymph node involvement, distant metastasis and higher proliferation measured by ki-67 expression.

    Full Text Available Despite the advances that have been made in the fields of molecular and cell biology, there is still considerable debate explaining how the breast cancer cells progress through carcinogenesis and acquire their metastatic ability. The lack of preventive methods and effective therapies underlines the pressing need to identify new biomarkers that can aid early diagnosis and may be targets for effective therapeutic strategies. In this study we explore the pituitary tumor-transforming gene 1 (PTTG1 expression in primary ductal breast carcinoma, lymph node infiltration, and distant metastases. Three human cell lines, 184B5 derived from normal mammary epithelium, HCC70 from a primary ductal carcinoma, and MDA-MB-361 from a breast metastasis, were used for quantifying PTTG1 mRNA expression. The PTTG1 immunohistochemical expression was carried out on specimens taken from eight patients with invasive ductal breast cancer who underwent surgical treatment and followup for five years retrospectively selected. The study demonstrated that PTTG1 is expressed gradually in primary ductal breast carcinoma, lymph node infiltration, and distant metastases. Our findings suggest that the immunohistochemical evaluation of PTTG1 expression might be a powerful biomarker of recognition and quantification of the breast cancer cells in routine pathological specimens and a potential target for developing an effective immunotherapeutic strategy for primary and metastatic breast cancer.

    A controversy of the role of Epstein-Barr virus (EBV) infection in breast carcinomas has been reported in the literature. We carried on this research to explore possible association between EBV infection and breast invasive ductal carcinoma (IDC) in Egyptian women attending our center. This study carried out at Sohag university hospital on 84 paraffin embedded samples of breast tissue, of them 42 breast IDC as the case group and 42 breast fibroadenomas as the control group. Nested PCRand immunohistochemistry (IHC) done separately for all samples to identify the Epstein-Barr nuclear antigen-1 (EBNA-1) gene and EBV latent membrane protein-1 (LMP-1) respectively, in breast cancer cells and controls. Specimen considered positive when both (EBNA-1) gene and LMP-1 were detected using PCR and IHC separately for the same sample, this was achieved by 10/42 (23.81%) of breast IDC (case group) and 6/42 (14.29%) of breast fibro-adenomas (control group) (P-value=0.4). Nodal involvement was the only parameter that demonstrated a significant statistical relationship with EBV presence in cancerous tissue with p-value=0.003. Our research could not find a significant statistical association between EBV infection and breast IDC in Egyptian women attending our center, but, there might be an association between the existence of EBV and tumor aggressiveness.

    Enumeration of circulating tumor cells (CTCs) isolated from the peripheral blood of breast cancer patients holds promise as a clinically relevant, minimally invasive diagnostic test. However, CTC utility has been limited as a prognostic indicator of survival by the inability to stratify patients beyond general enumeration. In comparison, histological biopsy examinations remain the standard method for confirming malignancy and grading malignant cells, allowing for cancer identification and then assessing patient cohorts for prognostic and predictive value. Typically, CTC identification relies on immunofluorescent staining assessed as absent/present, which is somewhat subjective and limited in its ability to characterize these cells. In contrast, the physical features used in histological cytology comprise the gold standard method used to identify and preliminarily characterize the cancer cells. Here, we superimpose the methods, cytologically subtyping CTCs labeled with immunohistochemical fluorescence stains to improve their prognostic value in relation to survival. In this single-blind prospective pilot study, we tracked 36 patients with late-stage breast cancer over 24 months to compare overall survival between simple CTC enumeration and subtyping mitotic CTCs. A power analysis (1-β = 0. 9, α = 0.05) determined that a pilot size of 30 patients was sufficient to stratify this patient cohort; 36 in total were enrolled. Our results confirmed that CTC number is a prognostic indicator of patient survival, with a hazard ratio 5.2, p = 0.005 (95 % CI 1.6-16.5). However, by simply subtyping the same population based on CTCs in cytological mitosis, the hazard ratio increased dramatically to 11.1, p cancer, (2) mitotic CTCs may significantly correlate with shortened overall survival, and (3) larger and more defined patient cohort studies are clearly called for based on this initial pilot study.

    Full Text Available Abstract Background Breast cancer incidence in India is on rise. We report epidemiological, clinical and survival patterns of breast cancer patients from community perspective. Methods All breast cancer patients treated at this hospital from July 2000 to July 2005 were included. All had cytological or histological confirmation of breast cancer. TNM guidelines for staging and Immunohistochemistry to assess the receptor status were used. Either lumpectomy with axillary lymph node dissection or Modified radical mastectomy (MRM was done for operable breast cancer, followed by 6 cycles of adjuvant chemotherapy with FAC or CMF regimens to patients with pT >1 cm or lymph node positive or estrogen receptor negative and radiotherapy to patients after breast conservation surgery, pT size > 5 cm, 4 or more positive nodes and stage IIIB disease. Patients with positive Estrogen receptor or Progesterone receptor were advised Tamoxifene 20 mg per day for 3 years. Descriptive analysis was performed. Independent T test and Chi-square test were used. Overall survival time was computed by Kaplan – Meier method. Results Of 1488 cancer patients, 122 (8.2% had breast cancer. Of 122 patients, 96.7% had invasive breast carcinoma and 3.3% had sarcoma. 94% came from the rural and semi urban areas. Premenopausal women were 27%. The median age was 50 years. Stage I-6.8%, II-45.8%, III-22%, IV-6.8%, Bilateral breast cancer – 2.5%. The mean pT size was 3.9 cm. ER and PR were positive in 31.6% and 28.1% respectively. MRM was done in 93.8%, while 6.3% patients underwent breast conservation surgery. The mean of the lymph nodes dissected were 3. CMF and FAC regimens were used in 48.8% and 51.2% of patients respectively. FAC group were younger than the CMF group (43.6 yr vs. 54 yrs, P = 0.000. Toxicities were more in FAC than CMF group, alopecia (100% vs. 26.2%, grade2 or more emesis (31.8% vs. 9.2%, grade2 or more fatigue (40.9% vs.19%, anemia (43.1% vs. 16.6%. Median

    Full Text Available Abstract Background The homeobox gene HEX is expressed in several cell types during different phases of animal development. It encodes for a protein localized in both the nucleus and the cytoplasm. During early mouse development, HEX is expressed in the primitive endoderm of blastocyst. Later, HEX is expressed in developing thyroid, liver, lung, as well as in haematopoietic progenitors and endothelial cells. Absence of nuclear expression has been observed during neoplastic transformation of the thyroid follicular cells. Aim of the present study was to evaluate the localization and the function of the protein HEX in normal and tumoral breast tissues and in breast cancer cell lines. Methods HEX expression and nuclear localization were investigated by immunohistochemistry in normal and cancerous breast tissue, as well as in breast cancer cell lines. HEX mRNA levels were evaluated by real-time PCR. Effects of HEX expression on Sodium Iodide Symporter (NIS gene promoter activity was investigated by HeLa cell transfection. Results In normal breast HEX was detected both in the nucleus and in the cytoplasm. In both ductal and lobular breast carcinomas, a great reduction of nuclear HEX was observed. In several cells from normal breast tissue as well as in MCF-7 and T47D cell line, HEX was observed in the nucleolus. MCF-7 treatment with all-trans retinoic acid enhanced HEX expression and induced a diffuse nuclear localization. Enhanced HEX expression and diffuse nuclear localization were also obtained when MCF-7 cells were treated with inhibitors of histone deacetylases such as sodium butyrate and trichostatin A. With respect to normal non-lactating breast, the amount of nuclear HEX was greatly increased in lactating tissue. Transfection experiments demonstrated that HEX is able to up-regulate the activity of NIS promoter. Conclusion Our data indicate that localization of HEX is regulated in epithelial breast cells. Since modification of localization

    To investigate clinical implications of FDG uptake in the thyroid glands in patients with advanced breast carcinoma by comparing metabolic and morphologic patterns on positron emission tomography (PET)/computed tomography (CT). The institutional review board waived the requirement for informed consent. A retrospective analysis was performed in 146 women (mean age 54 years) with advanced breast carcinoma who received systemic treatment. All patients underwent PET-CT before and after treatment. All PET-CT studies were reviewed in consensus by two reviewers. Morphologic changes including volume and mean parenchymal density of the thyroid glands were evaluated. Maximum standardized uptake value (SUVmax) and total lesion glycolysis (TLG) were determined to evaluate metabolic changes. These parameters were compared between patients with chronic thyroiditis who received thyroid hormone replacement therapy and those who did not. Of the 146 patients, 29 (20%) showed bilaterally diffuse uptake in the thyroid glands on the baseline PET-CT scan. The SUVmax showed a linear relationship with volume (r = 0.428, p = 0.021) and the mean parenchymal density (r = -0.385, p = 0.039) of the thyroid glands. In 21 of the 29 patients (72%) with hypothyroidism who received thyroid hormone replacement therapy, the volume, mean parenchymal density, SUVmax, and TLG of the thyroid glands showed no significant changes. In contrast, 8 of the 29 patients (28%) who did not receive thyroid hormone replacement therapy showed marked decreases in SUVmax and TLG. Diffuse thyroid uptake on PET-CT represents active inflammation caused by chronic thyroiditis in patients with advanced breast carcinoma. Diffuse thyroid uptake may also address the concern about subclinical hypothyroidism which develops into overt disease during follow-up. (orig.)

    To evaluate the impact of MHC antigen expression on the survival of patients with cancer, 77 human breast carcinomas were investigated for the expression of beta 2-microglobulin (beta 2m), HLA-A,B,C and HLA-DR. Thirty-one benign breast tumours were stained for comparison. The results for the carcinomas were related to the survival data of the cancer patients. The expression of beta 2m, HLA-A,B,C and HLA-DR was significantly lower in malignant tumours compared to the benign lesions. Whereas al...

    Morphometric features of nuclear perimeter, nuclear area, feret ratio, and feret circle were studied in a series of 64 cases of ductal carcinoma in situ (DCIS) of the breast in Singapore women. The results were compared with pathologic parameters of tumor size, nuclear grade, necrosis, cell polarization, and architectural pattern. There was statistically significant correlation between nuclear perimeter and area with all the pathologic parameters, with the strongest association observed for nuclear grade (P parameters and feret ratio or circle, indicating that nuclear roundness or lack of it did not factor as a significant component in the pathologic assessment.

    Accelerated whole-breast radiotherapy (RT) with tumor bed boost in the treatment of early invasive breast cancer has demonstrated equivalent local control and cosmesis when compared with standard RT. Its efficacy in the treatment of ductal carcinoma in situ (DCIS) remains unknown. Patients treated for DCIS with lumpectomy and negative margins were eligible for 2 consecutive hypofractionated whole-breast RT clinical trials. The first trial (New York University [NYU] 01-51) prescribed to the whole breast 42 Gy (2.8 Gy in 15 fractions) and the second trial (NYU 05-181) 40.5 Gy (2.7 Gy in 15 fractions) with an additional daily boost of 0.5 Gy to the surgical cavity. Between 2002 and 2009, 145 DCIS patients accrued, 59 to the first protocol and 86 to the second trial. Median age was 56 years and 65% were postmenopausal at the time of treatment. Based on optimal sparing of normal tissue, 79% of the patients were planned and treated prone and 21% supine. At 5 years' median follow-up (60 months; range 2.6-105.5 months), 6 patients (4.1%) experienced an ipsilateral breast recurrence in all cases of DCIS histology. In 3/6 patients, recurrence occurred at the original site of DCIS and in the remaining 3 cases outside the original tumor bed. New contralateral breast cancers arose in 3 cases (1 DCIS and 2 invasive carcinomas). Cosmetic self-assessment at least 2 years after treatment is available in 125 patients: 91% reported good-to-excellent and 9% reported fair-to-poor outcomes. With a median follow-up of 5 years, the ipsilateral local recurrence rate is 4.1%, comparable to that reported from the NSABP (National Surgical Adjuvant Breast and Bowel Project) trials that employed 50 Gy in 25 fractions of radiotherapy for DCIS. There were no invasive recurrences. These results provide preliminary evidence that accelerated hypofractionated external beam radiotherapy is a viable option for DCIS. Copyright © 2012 Elsevier Inc.

    Sarcoma occurring in soft tissues after radiotherapy is a rare complication of radiation treatment of tumours. It was most often described after treatment for breast cancer as well as for non-Hodgkin lymphoma and cervical carcinoma. The time interval between the radiation therapy and the development of the sarcoma can be very wide. Treatment demands radical surgical resection of the sarcoma with the edge of the resected tissue without tumour cells. In some cases, this is followed by chemotherapy or radiotherapy. The median survival time is 23 months, the longest survival being associated with sarcomas removed in a radical way. We present the case of a female patient with recurring leiomyosarcoma of the chest wall after radiotherapy for cancer of the right breast. In 2006, this 62-year-old patient was operated on to keep her right breast with axilla exenteration. After the surgery, hormonal therapy was followed by adjuvant radiotherapy of the right breast and the adjacent axilla. We used a linear accelerator and the total amount of radiation was 50 Gy (2 Gy fractionally once a day, five days a week). Four years after the operation, leiomyosarcoma was diagnosed in the pectoral muscle at the site where the tumour of the right breast had been excised. Between 2011 and 2013, a total of five operations of re-occurring sarcoma were performed - two excisions of the tumour, a mastectomy, rib resection and, at last, block resection of the chest wall. Adjuvant oncological treatment was not indicated. The patient, now being 69 years old, is still in a good physical and mental condition without any generalization of the disease. Sarcoma of the chest wall is a relatively rare consequence of radiotherapy for breast cancer. Sarcoma treatment involves radical surgical resection of the tumour whenever possible. The surgery is mostly followed by radiotherapy which, however, is impossible in a patient after breast-preserving surgery for carcinoma with radiotherapy. Chemotherapy is not

    Objective was to compare initial metastatic breast carcinoma (MBC) with recurrent MBC and assess their biologic phenotypes and clinical behaviors. A comparison of clinical and biological characteristics and median overall survival times were assessed in the 251 patients with MBC at the Division of Medical Oncology, Ege University School of Medicine and the Division of radiation Oncology, Tepecik Government Hospital, Izmir, Turkey between 1995 and 2004. Hormone receptors, c-erb B-2,ki-67 and p53 expressions were performed by immunohistochemistry. Out of 251 MBC patients, 206 patients had recurrent MBC and 45 had initial MBC. Regarding survival there was no difference between the recurrent MBC group and the initial MBC group. The initial MBC group had a higher proportion of T4 tumors (46% versus 27%), a lower proportion of T-1-2 tumors (31% versus 55%; p=0.01), and higher percentage of patients with high Ki-67 expression (64% versus 49%; p=0.05). Multivariate analysis showed that T stage was an independent prognostic factor (p=0.02). Patients with initial MBC tended to present with larger tumors. This relationship can be explained by delayed diagnosis. The potential for reducing death rates from breast cancer is contingent on educational improvement and increased screening rates. (author)

The case concerns a 71-year-old female patient treated for ankylosing spondylitis, with a positive family history of breast cancer. The patient presented at the surgical clinic for incision of an abscess of the mammary gland localized in the lower inner quadrant that was a consequence of previous trauma to the right breast. The abscess was incised and the serosanguineous contents were evacuated. The wound was drained and antibiotics (Dalacin with Metronidazol were administered for the period of 10 days. During the treatment, a cutaneous fistula was formed. At the incision site, a hard thickening was palpable (tumor. Core needle biopsy of the clinically palpable tumor was performed and the purulent material from the fistula was collected for a culture test. Complete blood count did not reveal leucocytosis. In accordance with the obtained sensitivity report, the patient was started on antibiotics again. Breast ultrasound performed upon the completion of the antibiotic therapy, in the right breast, revealed two solidcystic oval lesions with thick echogenic walls and blurred margins. Both masses contained dense levels of fluid material and solid polycyclic structures. On sonoelastography, the lesions were heterogeneous with a high Young’s modulus. In the right axillary fossa, ultrasound examination revealed three abnormal lymph nodes enlarged to 31 mm length, which were rounded, hypoechoic and without visible sinuses. Histopathology of the core needle biopsy performed at admittance and after the antibiotic therapy indicated a breast abscess (presence of fibrinous and partly fibrinopurulent material. The mass was finally resected to confirm histopathology. The resected material revealed the presence of an invasive, moderately differentiated cribriform carcinoma, which developed within a cyst, with a

    A 69-year-old white Italian woman was first seen at Memorial Sloan-Kettering Cancer Center in 1981 concerning several skin growths on her back. The patient had had several basal cell carcinomas surgically removed from her back during the preceding 5 years. There was no history of arsenic ingestion or prolonged sun exposure and her family history was negative for skin cancer. The patient had developed pulmonary tuberculosis in 1938 and was treated with pneumothorax therapy. She had had more than 50 fluoroscopic examinations of the chest following this therapy, as well as multiple diagnostic x-ray films since that time. On the back, clustered in the interscapular region, were multiple scars and nine erythematous nodules with pearly borders, telangiectasia, and translucent surfaces. Within several nodules there were areas of light and dark brown pigmentation. Biopsy of all lesions revealed basal cell carcinoma, some of which were pigmented, without evidence of chronic radiodermatitis. All lesions were treated with curettage and electrodesiccation three times with good cosmetic results.

    Full Text Available Breast cancer is a major cause of mortality in women due to malignant diseases and is the most prevalent type of cancer in western countries. According to investigations which has been done in Iran so far, the prevalence of disease in our country is also very high, therefore complete attention to clinical and pathological findings of this disease would be extremely essential. In this study, the direct relationship between axillary lymph node involvement and the aggressiveness of invasive ductal carcinoma has been brought into consideration. This study is a case series of 90 patients which all of them have had radical mastectomy because of breast cancer and all their samples has been referred to the center of pathology of Imam hospital. Based on modified Bloom-Richardson grading, all the samples have been graded. The study of all lymph node samples related to above cases has also been conducted along with the main study. The most frequent ages of disease was 31 to 40 and left breast had most involvement. From all cases, 12.2% were in grade I with 27.2% lymph node involvement, 66.7% grade II with 73.4% lymph node involvement and 21.1% in grade III with 100% lymph node involvement (P=0.00008. Based on statistical analysis we concluded that the axillary lymph node involvement in breast cancer is strongly associated with the aggressiveness of invasive ductal carcinoma. This important point should not be neglected in planning for treatment of this kind of disease.

    Background: Invasive lobular carcinoma (ILC) is more often multifocal and bilateral than invasive ductal carcinoma. MRI is usually recommended for detection of all ILC sites. The performance of known diagnostic breast MRI criteria for ILC characterization has not been evaluated to date using bilateral mastectomy specimens as gold standard. Purpose: To determine the value of BI-RADS 2006 MRI criteria for ILC detection and characterization, using pathological examination of bilateral mastectomy specimens as the reference standard. Material and Methods: Between 2004 and 2007, we retrospectively included all patients with pathologically documented ILC referred to our institution for bilateral mastectomy and preoperative bilateral breast MRI. The location, diameter, and characteristics (BI-RADS) of all lesions were compared with pathological findings. The sensitivity and positive predictive value of bilateral breast MRI for the diagnosis of ILC were calculated. Association of MRI BI-RADS categorical variables and characterization of ILC were assessed (Fisher exact test). Results: Among 360 patients treated for ILC in 2004-2007, 15 patients qualified for this study. Thirty-one ILC foci were found on pathological examination (30 ipsilateral and 1 contralateral tumor; mean diameter 23 mm; range 2-60 mm) and all were identified on MRI, with 90% of masses and 10% non-mass-like enhancements; MRI features significantly associated with ILC included absence of smooth margins (P = 0.02) and rim-shaped enhancement (P = 0.039). Enhancement kinetics of the 31 foci were evenly distributed among wash-out, plateau, and persistent profiles. Eleven additional lesions were seen on MRI, mainly corresponding to fibrocystic disease; 91% presented as masses and 9% had a wash-out profile. Conclusion: Based on the 2006 BI-RADS criteria, breast MRI shows a high sensitivity for ILC detection, at the expense of a 26% false-positive rate, suggesting that a pathological proof by US- or MR

    Full Text Available Although subsequent breast cancer risk after primary lobular carcinoma in situ (LCIS has been studied intensively, whether the risk of second breast cancer after first LCIS varies with hormone receptor (HR status of primary tumor remains unclear.We identified 10,304 women with primary pure unilateral LCIS between 1998 and 2007 from the Surveillance, Epidemiology and End Results (SEER 18 Registries. Kaplan-Meier estimates of 5 or 10-year probabilities of second ipsilateral breast cancers (IBCs and contralateral breast cancers (CBCs were calculated. Multivariable Cox proportional model was performed to identify impact of HR status of primary LCIS, and other demographic, clinicopathologic or treatment characteristics on risk of second IBCs or CBCs.Of the 10,304 women with primary LCIS included in this study, 9949 (96.5% patients had HR+ tumors, and 355 (3.5% had HR- tumors. Multivariable-adjusted analyses showed that although there was no difference in risk of total second IBCs between women with HR+ and HR- LCIS (P = 0.152, patients with HR+ LCIS had a statistically lower risk of second invasive IBCs compared to those with HR- LCIS (hazard ratio 0.356, 95% CI 0.141-0.899, P = 0.029. Women with primary HR+ LCIS had lower risks of both second total and invasive CBCs compared to those with HR- LCIS (total CBCs: hazard ratio 0.340, 95% CI 0.228-0.509, P<0.001; invasive CBCs: hazard ratio 0.172, 95% CI 0.108-0.274, P<0.001. Additionally, black women had a 2-fold risk of developing subsequent total IBCs than white women (P = 0.028.This population-based study demonstrated that the risk of second breast cancers was significantly increased in women with HR- first LCIS compared to those with HR+ LCIS. These findings warrant intensive surveillance for second breast cancers in HR- LCIS survivors.

    In humans, two main types of membrane melatonin receptors have been identified, MT1 and MT2. Expression of MT1 in neoplastic cells seems to increase the efficacy of melatonin's oncostatic activity. The purpose of this study was to determine the distribution and the intensity of MT1 expression in breast cancer cells and to correlate it with clinicopathological factors. Immunohistochemical studies (IHC) were conducted on 190 cases of invasive ductal breast carcinomas (IDC) and molecular studies were performed on 29 cases of frozen tumor fragments and selected breast cancer cell lines. Most of the studied tumors manifested a membranous/cytoplasmic IHC expression of MT1. In IDC, the MT1 expression was higher than in fibrocystic breast disease. MT1 expression was higher in estrogen receptor positive (ER+) and HER2 positive (HER2+) tumors. Triple negative tumors (TN) manifested the lowest MT1 expression level. The lowest MT1 protein expression level was noted in the TN breast cancer cell line MDA-MB-231 compared with ER+ cell lines MCF-7 and SK-BR-3. MT1 mRNA expression was negatively correlated with the malignancy grade of the studied IDC cases. Moreover, higher MT1 expression was associated with patients' longer overall survival (OS) in the group of ER+ breast cancers and treated with tamoxifen. Multivariate analysis indicated that MT1 was an independent prognostic factor in the ER+ tumors for OS and event-free survival in the ER+ tumors. The results of this study may point to a potential prognostic and therapeutic significance of MT1 in IDC. © 2013 John Wiley & Sons A/S. Published by Blackwell Publishing Ltd.

    The POK family of proteins plays an important role in not only embryonic development and cell differentiation, but also in oncogenesis. Leukemia/lymphoma-related factor (LRF) belongs to the POK family of transcriptional repressors and is also known as POK erythroid myeloid ontogenic factor (POKEMON), which binds to short transcripts of HIV-1 (FBI-1) and TTF-1 interacting peptide (TIP21). Its oncogenic role is known only in lymphoma, non-small cell lung carcinoma, and malignant gliomas. The functional expression of LRF in human breast carcinoma has not yet been confirmed. The aim of this study was to investigate and compare the expression of LRF in human breast cancer tissues and other human tumors. The expression of LRF mRNA transcripts and protein was observed in twenty human benign and malignant breast biopsy tissues. Expression of LRF was observed in several formalin-fixed tissues by immunohistochemistry and immunofluorescence. All malignant breast tissues expressed mRNA transcripts and protein for LRF. However, 40% and 15% benign breast biopsy tissues expressed LRF mRNA transcripts and protein, respectively. The overall expression of LRF mRNA transcripts and total protein was significantly more in malignant breast tissues than the benign breast tissues. LRF expression was also observed in the nuclei of human colon, renal, lung, hepatocellular carcinomas and thymoma tumor cells. In general, a significantly higher expression of LRF was seen in malignant tissues than in the corresponding benign or normal tissue. Further studies are warranted to determine the malignant role of LRF in human breast carcinoma. PMID:20471975

    Full Text Available Background/Aim. Most human cancers, including breast one, increase in frequency with aging. The aim of this study was to explore the hypothesis that aging also alters breast cancer biology. Methods. The study included 120 women with primary invasive ductal carcinoma of the breast. We correlated the patients age and diagnosis with the commonly used clinical, pathological factors and newer tumor biomarkers. Immunohistochemical staining was conducted for p53, c-erbB-2, Ki-67, estrogen (ER, progesterone (PR receptors, and angiogenesis. Results. In our study, the patients with axillary lymph node metastases and negative steroid hormone receptors (ER and PR were significantly younger than the patients with nodal involvement and positive hormone receptors. There was also a significant association between the patients age, diagnosis and angiogenesis. No association was found between the patients age and tumor size, histological grade, p53, c-erbB-2, and Ki-67. Conclusion. The results of our study supported only partially the hypothesis that the breast cancer biology is significantly affected by a patient's age.

    Microcalcifications (MCs) are routinely used to detect breast cancer in mammography. Little is known, however, about their materials properties and associated organic matrix, or their correlation to breast cancer prognosis. We combine histopathology, Raman microscopy, and electron microscopy to image MCs within snap-frozen human breast tissue and generate micron-scale resolution correlative maps of crystalline phase, trace metals, particle morphology, and organic matrix chemical signatures within high grade ductal carcinoma in situ (DCIS) and invasive cancer. We reveal the heterogeneity of mineral-matrix pairings, including punctate apatitic particles (<2 µm) with associated trace elements (e.g., F, Na, and unexpectedly Al) distributed within the necrotic cores of DCIS, and both apatite and spheroidal whitlockite particles in invasive cancer within a matrix containing spectroscopic signatures of collagen, non-collagen proteins, cholesterol, carotenoids, and DNA. Among the three DCIS samples, we identify key similarities in MC morphology and distribution, supporting a dystrophic mineralization pathway. This multimodal methodology lays the groundwork for establishing MC heterogeneity in the context of breast cancer biology, and could dramatically improve current prognostic models.

    Mucins are highly immunogenic glycoproteins that are abundantly expressed by breast and other adenocarcinomas. In order to progress in the understanding of the structure immunity relationship of the breast tumor associated mucin and normal tissue mucin, two forms of breast carcinoma associated mucin, muc7-BV and pem-BV, were expressed in a baculovirus expression system. The muc7-BV was constructed by inserting the seven tandem repeats of mucin core cDNA fragment into transfer vector pAc360, forming a fusion protein containing 14 amino acids of the baculovirus polyhedrin N-terminus. The pem-BV was constructed by cloning full-length mucin cDNA into the transfer vector pVL1392. The recombinant mucins were purified using immunoaffinity chromatography. The purified muc7-BV and pem-BV had molecular weights of 28 and 59 kd, respectively. No carbohydrate was detected on these recombinant mucins and is speculated to explain why both forms of recombinant mucin showed strong affinity to tumor-specific monoclonal antibody SM3. These recombinant mucins may have the potential value to develop vaccines against breast and other adenocarcinomas and to induce cytotoxic T-lymphocyte lines for immunotherapy of the same.

    Large core biopsy is a recently introduced method for pre-operative evaluation of breast lumps. The aim of this study was to evaluate the usefulness of this technique in providing pre-operative diagnostic and prognostic information that can lead to a correct line of treatment. We compared 41 cases of breast carcinomas diagnosed both by core biopsies and surgically removed samples. A high (93%) diagnostic agreement was obtained. Moreover, we found a significant correlation for mitotic count (r = 0.76), oestrogen receptor (r = 0.78), progesterone receptor (r = 0.80), p53 (r = 0.86) and c-erbB-2 (r = 0.90) analysis between core biopsy and definitive surgical pathology. An agreement for histological grading evaluation between the two techniques was obtained in 32 out of 40 cases (k = 0.65) whereas in the other cases, a lower grade was assigned by evaluating core biopsies. These findings suggest that percutaneous core breast biopsy is a valid tool for pre-operative management of breast lesions, but this should be confirmed in larger, prospective studies.

    Purpose of this article is to evaluate the most frequent mammographic, US and MR findings of invasive lobular carcinoma and the role of MRI in defining multifocality and/or multi centricity of this tumor histotype. 45 lobular carcinomas in 39 patients were studied and selected from 421 breast cancers. Core biopsy with a 14G needle was performed in 39 cases, under US guidance in 36/39 and under mammographic guidance in 3/39 cases. Surgical biopsy was performed in 2 cases and the diagnosis could be made only after mastectomy in 5 cases. All patients were examined with mammography and US and (10-13 MHz) and 8 also with MRI. 28/46 palpable lesions (60.9%). Core biopsy correctly diagnosed 38/39 lesions (97.4%). The most frequent mammographic findings was that of a nodular opacity without microcalcifications (34.8%), followed by a mass with spiculate d borders (30.4%). Microcalcifications were seen in one case only (2.2%). Mammography detected no abnormalities in 15.2% of cases, but US showed a lesion in 2 of these cases. The most frequent US pattern was that of a hypoechoic lesion (43.5%), followed by posterior US beam attenuation. No US signs of abnormality were seen 15.2%. MRI correctly detected 13 lesions. Contrast enhancement was greater than 70% at one minute in 10 cases and greater than 40% in one case; two lesions exhibited atypical slow contrast enhancement, peaking at 5 minutes. MRI detected 5 lesions missed both mammography and US and showed multifocal (3 and 2) lesions where the other techniques had detected one lesion only. At mammography and US invasive lobular carcinoma exhibits no different features than ductal carcinoma but is difficult to identify especially in its early stages. US is a useful tool especially to characterize mammography-detected lesions but in the experience it also demonstrated 2 lesions missed at mammography. MRI is a precious examination to define the multifocal, multi centric or bilateral character of invasive lobular carcinoma

    Breast carcinoma is the most common malignancy and leading cause of cancer-related deaths in women worldwide including Saudi Arabia. Breast cancer in Saudi women develops at a much early age with median age of onset of 49 years compared to 62 years observed in patients from USA. Aberrations in wingless and integration site growth factor (Wnt) signaling pathway have been pathologically implicated in development of breast cancers and hence its role was examined in Saudi patients. We immunohistochemically examined various components of Wnt signaling pathway including β-catenin, tumor suppressor proteins, adenomatous polyposis coli (APC), and Axin, expression of naturally occurring pathway antagonists such as Dickkopf Wnt signaling pathway inhibitor 3 (DKK3), FRP2, and WIF1, as well as Wnt target cyclin D1 and c-Myc to establish if the pathway is constitutively activated in breast cancers arising in Saudi women. Cytoplasmic β-catenin, indicative of activation of the pathway, was observed in 24% of cases. Expression of APC and Axin, which are components of β-catenin destruction complex, was lost in 5% and 10% of tumors, respectively. Additionally, Wnt signaling inhibitors DKK3, FRP2, and Wnt inhibitory factor 1 (WIF1) were not expressed in 8%, 14%, and 5% breast tumors, respectively. Overall, accumulation of cytoplasmic β-catenin and downregulation of other Wnt pathway proteins (APC/Axin/DKK3/FRP2/WIF1) were found in approximately half of the breast cancers (47%) in our cohort. Consistent with this, analysis of Wnt target genes demonstrated moderate-to-strong expression of c-Myc in 58% and cyclin D1 in 50% of breast cancers. Deregulation of Wnt pathway was not associated with age of onset of the disease, tumor grade, and triple-negative status of breast cancers. High level of deregulated expression of Wnt pathway proteins suggests its important role in pathogenesis of breast cancers arising in Saudi women who may benefit from development of therapeutic drugs

    The aim of this study was to evaluate the contribution of the BRCA1 and BRCA2 promoter methylation in the pathogenesis of sporadic breast cancer in Tunisian patients. Breast carcinoma tissues (n=117) and available paired normal breast tissues (n=65) from Tunisian women who had no family history were investigated for the methylation status of BRCA1 and BRCA2 promoters using methylation-specific PCR. Breast specimens from women without carcinoma (16 fibroadenomas and 5 mastopathies) were used as control. Hypermethylation of BRCA1 and BRCA2 promoters was detected respectively in 60.7% and 69.2% of the carcinoma tissues, and in only 7.7% and 4.6% of the paired normal breast tissues. None of the fibroadenomas and mastopathies showed hypermethylation. Correlations were found between BRCA1 and BRCA2 hypermethylation and decrease in their mRNA expression (p=0.02 and p=0.009, respectively). Moreover, BRCA1 methylation correlates with patients age (p=0.01) and triple negative (ER-, PR-, HER2-) tumors (p=0.01). Patients with methylated BRCA1 and/or BRCA2 had a significant prolonged survivals compared to those with unmethylated tumors (p=0.002). Our results suggest an important role of BRCA1 and BRCA2 promoter methylation in breast cancer development in the Tunisian population. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Full Text Available Abstract Background ADAM33 protein is a member of the family of transmembrane glycoproteins composed of multidomains. ADAM family members have different activities, such as proteolysis and adhesion, making them good candidates to mediate the extracellular matrix remodelling and changes in cellular adhesion that characterise certain pathologies and cancer development. It was reported that one family member, ADAM23, is down-regulated by promoter hypermethylation. This seems to correlate with tumour progression and metastasis in breast cancer. In this study, we explored the involvement of ADAM33, another ADAM family member, in breast cancer. Methods First, we analysed ADAM33 expression in breast tumour cell lines by RT-PCR and western blotting. We also used 5-aza-2'-deoxycytidine (5azadCR treatment and DNA bisulphite sequencing to study the promoter methylation of ADAM33 in breast tumour cell lines. We evaluated ADAM33 methylation in primary tumour samples by methylation specific PCR (MSP. Finally, ADAM33 promoter hypermethylation was correlated with clinicopathological data using the chi-square test and Fisher's exact test. Results The expression analysis of ADAM33 in breast tumour cell lines by RT-PCR revealed gene silencing in 65% of tumour cell lines. The corresponding lack of ADAM33 protein was confirmed by western blotting. We also used 5-aza-2'-deoxycytidine (5-aza-dCR demethylation and bisulphite sequencing methodologies to confirm that gene silencing is due to ADAM33 promoter hypermethylation. Using MSP, we detected ADAM33 promoter hypermethylation in 40% of primary breast tumour samples. The correlation between methylation pattern and patient's clinicopathological data was not significantly associated with histological grade; tumour stage (TNM; tumour size; ER, PR or ERBB2 status; lymph node status; metastasis or recurrence.

    Full Text Available O câncer de mama em homens é uma doença incomum. A cada 150 casos de câncer de mama é esperada a ocorrência de apenas um no sexo masculino. Devido à baixa incidência desta neoplasia, grande parte do seu conhecimento é oriunda do carcinoma de mama no sexo feminino, cujos parâmetros diagnósticos, prognósticos e terapêuticos são bem estabelecidos na literatura. Entretanto, a distribuição dos fenótipos moleculares dos carcinomas da mama masculina é pouco conhecida. Pela análise de dados clínicos e imuno-histoquímicos estudamos os diferentes perfis de uma amostra de 20 casos de tumores invasores de mama em homens. Utilizamos um painel de cinco anticorpos composto por receptor de estrogênio, citoqueratinas 5/6, citoqueratinas 8/18, HER-1 e HER-2. Dos 20 casos examinados, 19 eram carcinomas do tipo ductal não-especial (95% e um do tipo lobular (5%. A maioria dos casos foi composta por mastectomias (65%, sendo a média de tamanho das neoplasias de 2,8 cm e o grau histológico mais freqüente o II (60%. Do total, 86,6% dos casos apresentaram metástases linfonodais. O número médio de linfonodos comprometidos foi de 5,2 nas amostras com axila positiva.

    Introduction: With a molecular weight an order of magnitude lower than antibodies but possessing comparable affinities, Nanobodies (Nbs) are attractive as targeting agents for cancer diagnosis and therapy. An anti-HER2 Nb could be utilized to determine HER2 status in breast cancer patients prior to trastuzumab treatment. This provided motivation for the generation of HER2-specific 5F7GGC Nb, its radioiodination and evaluation for targeting HER2 expressing tumors. Methods: 5F7GGC Nb was radioiodinated with 125 I using Iodogen and with 131 I using the residualizing agent N ε -(3-[ 131 I]iodobenzoyl)-Lys 5 -N α -maleimido-Gly 1 -GEEEK ([ 131 I]IB-Mal-D-GEEEK) used previously successfully with intact antibodies. Paired-label internalization assays using BT474M1 cells and tissue distribution experiments in athymic mice bearing BT474M1 xenografts were performed to compare the two labeled Nb preparations. Results: The radiochemical yields for Iodogen and [ 131 I]IB-Mal-D-GEEEK labeling were 83.6 ± 5.0% (n = 10) and 59.6 ± 9.4% (n = 15), respectively. The immunoreactivity of labeled proteins was preserved as confirmed by in vitro and in vivo binding to tumor cells. Biodistribution studies showed that Nb radiolabeled using [ 131 I]IB-Mal-D-GEEEK, compared with the directly labeled Nb, had a higher tumor uptake (4.65 ± 0.61% ID/g vs. 2.92 ± 0.24% ID/g at 8 h), faster blood clearance, lower accumulation in non-target organs except kidneys, and as a result, higher concomitant tumor-to-blood and tumor-to-tissue ratios. Conclusions: Taken together, these results demonstrate that 5F7GGC anti-HER2 Nb labeled with residualizing [ 131 I]IB-Mal-D-GEEEK had better tumor targeting properties compared to the directly labeled Nb suggesting the potential utility of this Nb conjugate for SPECT ( 129 I) and PET imaging ( 124 I) of patients with HER2-expressing tumors.

    Breast invasive ductal carcinoma (IDC) and invasive lobular carcinoma (ILC) have different metastatic patterns, but the exact pattern of metastases from ILC is poorly known. This study aimed to determine the frequency of ILC metastases in atypical locations, with an emphasis on gastric metastases. Patients with ILC treated at the Saint-Sacrement Hospital (Quebec City, Canada) and the Maisonneuve-Rosemont Hospital (Montreal, Canada) between January 2003 and December 2009 were retrospectively reviewed. Demographic, clinical, and follow-up data were retrieved from the medical charts. Metastases that were diagnosed during follow-up were recorded. Among the 481 patients with ILC, 74 (15.4%) were diagnosed with metastases after a median follow-up of 46 months. Among these 74 patients, 41.9% had metastases in atypical sites. Five patients were diagnosed with histologically confirmed gastric metastases of ILC. Metastases of breast ILC to atypical sites might be more frequent than previously reported. Clinicians should keep a high level of suspicion when a patient with a history of ILC develops digestive symptoms. It is important to differentiate metastases from a primary GI tumor by using immunohistochemical markers. J. Surg.

    Expression of hepatocyte growth factor (HGF) and its tyrosine kinase receptor, c-Met, is positively correlated with breast carcinoma progression. We found that in invasive and metastatic MTLn3 breast carcinoma cells, HGF stimulated both initial adhesion to and motility on the extracellular matrix (ECM) ligands laminin 1, type I collagen, and fibronectin. Next, analysis with function-perturbing antibodies showed that adhesion to the different ECM proteins was mediated through specific beta1 integrins. In MTLn3 cells, HGF induced rapid tyrosine phosphorylation and activation of both c-Met and focal adhesion kinase (FAK). Cell anchorage and adhesion to the ECM substrates was required for HGF-induced FAK activation, since HGF failed to trigger tyrosine phosphorylation of FAK in suspended cells. Our results provide evidence that the 2 signaling pathways, integrin/ECM and c-Met/HGF, cooperate synergistically to induce FAK activation in an adhesion-dependent manner, leading to enhanced cell adhesion and motility. Moreover, we found that a FRNK (the FAK-related non-kinase)-like molecule is expressed in MTLn3 cells. Since FRNK acts as a competitive inhibitor of FAK function, our results suggest that a FRNK-like protein could facilitate disassembly of focal adhesions and likely be responsible for the HGF-induced scattering and motility of MTLn3 cells.

    Full Text Available Objective: The aim is to show ultrasound (US findings of additional malignant lesions of breast carcinoma visualized on targeted second-look US that were not identified by mammography or US prior to the time of diagnosis. Materials and Methods: A double-blind retrospective review of the US results from January 2008 through August 2010 of 228 patients with known breast cancer was conducted by two expert radiologists. The focus of the review was on the second-look US characteristics (following BI-RADS criteria of 26 documented additional malignant lesions of the 76 with successful sonographic correlation from the 123 lesions detected by magnetic resonance imaging (MRI. All of them, before the MRI, had an initial mammography and a US with a histopathological biopsy of the primary lesion. Results: Approximately 60 to 70% of the findings were classified as BI-RADS 2 and BI-RADS 3, while assessing the final US category. The review of the second-look US showed the size of the second malignant additional lesion ranged from 3 to 22 mm, of which 90% were smaller than 10 mm and 66% were smaller than 7 mm. Conclusions: Most additional malignant lesions, nonpalpable carcinomas, which were previously not detected by mammography and US at first-look diagnosis, were detected by a targeted second-look US examination. These lesions were of category BI-RADS 2 and BI-RADS 3 and smaller than 7 mm.

    Telomere dysregulation occurs in both the in situ and invasive stages of many carcinomas, including breast. Knockout experiments have identified several telomere-associated proteins required for proper telomere function and maintenance, including telomere repeat-binding factor 1 and 2 (TRF1 and TRF2), protection of telomeres (POT1), and TRF1-interacting nuclear factor 2 (TIN2). Using telomere content assays and quantitative reverse transcription-polymerase chain reaction (RT-PCR), we examined the relationship between telomere length and the mRNA levels of telomere-associated proteins in breast tumors. The levels of TRF2, TRF1, TIN2, and POT1 mRNA, but not telomerase reverse transcriptase (TERT) RNA, are inversely correlated with telomere content in breast tumors. Significant associations were identified between the mRNA levels of TRF1, TIN2, and POT1; however, there were no significant associations with the mRNA levels of TRF2 or TERT. These associations suggest that a complex transcriptional program coordinately regulates the expression of these mRNAs. We examined the promoter regions of the telomere-associated proteins to identify transcription factors consistent with the observed patterns of presumed coordinate expression. We demonstrated in human breast cancer cell lines that expressions of TRF1, TIN2, and POT1 are upregulated by dexamethasone, suggesting activation of the glucocorticoid receptor, whereas TERT, TRF2, TRF1, TIN2, and POT1 are upregulated by tumor necrosis factor-α (TNF-α), suggesting activation of the nuclear factor kappa B transcription factor. These findings link telomere content in breast tumors to the coordinate expression of several telomere-associated proteins previously shown to be negative regulators of telomere length in cell lines. The results further suggest a possible link between the expressions of the telomere-associated proteins and mediators of stress and inflammation. Telomere content assays and quantitative RT-PCR demonstrate

    Highlights: • Apparent diffusion coefficient is a quantitative parameter which reflects molecular water movement. • Grading is an independent prognostic factor which correlates with other histopathological features. • Apparent diffusion coefficient values were significantly different between G1 and G3 classes. - Abstract: Purpose: The aim of this study was to evaluate whether the apparent diffusion coefficient (ADC) provided by 3.0 T (3 T) magnetic resonance diffusion-weighted imaging (DWI) varied according to the grading of invasive breast carcinoma. Materials and methods: A total of 92 patients with 96 invasive breast cancer lesions were enrolled; all had undergone 3 T magnetic resonance imaging (MRI) for local staging. All lesions were confirmed by histological analysis, and tumor grade was established according to the Nottingham Grading System (NGS). MRI included both dynamic contrast-enhanced and DWI sequences, and ADC value was calculated for each lesion. ADC values were compared with NGS classification using the Mann–Whitney U and the Kruskal–Wallis H tests. Grading was considered as a comprehensive prognostic factor, and Rho Spearman test was performed to determine correlation between grading and tumor size, hormonal receptor status, HER2 expression and Ki67 index. Pearson's Chi square test was carried out to compare grading with the other prognostic factors. Results: ADC values were significantly higher in G1 than in G3 tumors. No significant difference was observed when G1 and G3 were compared with G2. Tumor size, hormonal receptor status, HER2 expression and Ki67 index correlated significantly with grading but there was a significant difference only between G1 and G3 related to the ER and PR status, HER2 expression and Ki67 index. There was no statistically significant difference in lesion size between the two groups. Conclusion: ADC values obtained on 3 T DWI correlated with low-grade (G1) and high-grade (G3) invasive breast carcinoma. 3

    Objective: To investigate histopathological and immuno phenotypic differences between breast carcinomas sporadic (CM E) and developed in the context of breast cancer (B C) Family (CM F). Methodology: The study included in the CME group (n = 34) patients (pts) with unilateral CM diagnosed after age 30 without family history of CM. In CM F group (n = 26) family members were included pts with 3 or more cases of CM (at least one diagnosed before age 50) or two cases with any of the following sub-criteria: at least one case diagnosed before age 35, paternal transmission, bilateral breast cancer, cancer ovary. Each group was subdivided into 2 subgroups according to age at diagnosis of CM: age equal to or greater than 40 years (subgroup 1) and age under 40 years (subgroup 2). It recorded the clinical characteristics and conventional anatomical and pathological parameters. By immunohistochemistry (IHC) expression of estrogen receptors was studied and progesterone (E R, P R), HER2, p3, bcl-2 and Ki67. Appropriate statistical tests were applied to Univariate and multivariate analyzes. Results: Mean age at diagnosis (45 vs 58, p <0.001) and tumor size (p <0.05) were lower in the CMF group than in the group with CME. In both groups predominant histological type was infiltrating ductal carcinoma NOS. He documented a tendency to higher histological grade and lower E R expression in CMF regarding CME. There were no differences in the expression of Pr, HER2, Ki67, bcl2 and p53. while in the CMF group no differences in tumor characteristics were observed by age diagnosis, in the CME, subgroup 2 showed a predominance of edges expansive growth, lower tubular differentiation, histological grade end stores III, minor component in situ, and low expression of RE. Discussion: Morphologic and immune phenotypic features are similar to the CMF studies documented in the United States and Europe, which agrees with the ancestral origin predominant in our population. Overall, the group presented

    The clinical outcomes and therapeutic strategies for infiltrating ductal carcinoma (IDC) and infiltrating lobular carcinoma (ILC) are not uniform. The primary objectives of this study were to identify the differences in the clinical characteristics and prognoses between ILC and IDC, and identify the high-risk population based on the hormone receptor status and metastasis sites. The Surveillance, Epidemiology, and End Results Program database was searched and patients diagnosed with ILC or IDC from 1990 to 2013 were identified. In total,796,335 patients were analyzed, including 85,048 withILC (10.7%) and 711,287 withIDC (89.3%). The ILC group was correlatedwith older age, larger tumor size, later stage, lower grade, metastasis disease(M1) disease, and greater counts ofpositive lymph nodesandestrogen-receptor-positive (ER)/progesterone receptor-positive (PR) positive nodes. The overall survival showed an early advantage for ILC but a worse outcome after 5 years. Regarding the disease-specific survival, the IDC cohort had advantages over the ILC group, both during the early years and long-term. In hormone status and metastasis site subgroup analyses, the ER+/PR+ subgroup had the best survival, while the ER+/PR- subgroup had the worst outcome, especially the ILC cohort. ILC and IDC had different metastasis patterns. The proportion of bone metastasis was higher in the ILC group (91.52%) than that in the IDC (76.04%), and the ILC group was more likely to have multiple metastasis sites. Survival analyses showed patients with ILC had a higher risk of liver metastasis (disease-specific survival[DSS]; P = 0.046), but had a better overall survival than the bone metastasis group (P<0.0001). We concluded that the long-term prognosis for ILC was poorer than that for IDC, and the ER+/PR- subgroup had the worst outcome. Therefore, the metastasis pattern and prognosis must be seriously evaluated, and a combination of endocrine therapy and chemotherapy should be considered. PMID

    Full Text Available Abstract Background Multiple primary cancers have a low incidence particularly when cancers are synchronous. Few cases of synchronous head and neck cancer and breast carcinoma are reported in the literature. Case presentation We report here an exceptional case of a 47 years old Moroccan woman presenting two synchronous cancers, the first in the nasopharynx and the second in the breast. The patient was treated successfully with a combined strategy associating chemotherapy, radiation therapy, and surgery. She remains disease free after 27 months of follow up. Conclusions Treatment strategy in the case of multiple primary cancers remains controversial because of the variety of presentations; initial aggressive treatment reports good results.

    Women diagnosed with lobular carcinoma in situ (LCIS) have a 3-fold to 10-fold increased risk of developing invasive breast cancer. The objective of this study was to evaluate the life expectancy (LE) and differences in survival offered by active surveillance, risk-reducing chemoprevention, and bilateral prophylactic mastectomy among women with LCIS. A Markov simulation model was constructed to determine average LE and quality-adjusted LE (QALE) gains for hypothetical cohorts of women diagnosed with LCIS at various ages under alternative risk-reduction strategies. Probabilities for invasive breast cancer, breast cancer-specific mortality, other-cause mortality and the effectiveness of preventive strategies were derived from published studies and from the National Cancer Institute's Surveillance, Epidemiology, and End Results database. Assuming a breast cancer incidence from 1.02% to 1.37% per year under active surveillance, a woman aged 50 years diagnosed with LCIS would have a total LE of 32.78 years and would gain 0.13 years (1.6 months) in LE by adding chemoprevention and 0.25 years (3.0 months) in LE by adding bilateral prophylactic mastectomy. After quality adjustment, chemoprevention resulted in the greatest QALE for women ages 40 to 60 years at LCIS diagnosis, whereas surveillance remained the preferred strategy for optimizing QALE among women diagnosed at age 65 years and older. In this model, among women with a diagnosis of LCIS, breast cancer prevention strategies only modestly affected overall survival, whereas chemoprevention was modeled as the preferred management strategy for optimizing invasive disease-free survival while prolonging QALE form women younger than 65 years.

  10. Mitochondrial calcium uniporter activity is dispensable for MDA-MB-231 breast carcinoma cell survival.

    Duane D Hall

    Full Text Available Calcium uptake through the mitochondrial Ca2+ uniporter (MCU is thought to be essential in regulating cellular signaling events, energy status, and survival. Functional dissection of the uniporter is now possible through the recent identification of the genes encoding for MCU protein complex subunits. Cancer cells exhibit many aspects of mitochondrial dysfunction associated with altered mitochondrial Ca2+ levels including resistance to apoptosis, increased reactive oxygen species production and decreased oxidative metabolism. We used a publically available database to determine that breast cancer patient outcomes negatively correlated with increased MCU Ca2+ conducting pore subunit expression and decreased MICU1 regulatory subunit expression. We hypothesized breast cancer cells may therefore be sensitive to MCU channel manipulation. We used the widely studied MDA-MB-231 breast cancer cell line to investigate whether disruption or increased activation of mitochondrial Ca2+ uptake with specific siRNAs and adenoviral overexpression constructs would sensitize these cells to therapy-related stress. MDA-MB-231 cells were found to contain functional MCU channels that readily respond to cellular stimulation and elicit robust AMPK phosphorylation responses to nutrient withdrawal. Surprisingly, knockdown of MCU or MICU1 did not affect reactive oxygen species production or cause significant effects on clonogenic cell survival of MDA-MB-231 cells exposed to irradiation, chemotherapeutic agents, or nutrient deprivation. Overexpression of wild type or a dominant negative mutant MCU did not affect basal cloning efficiency or ceramide-induced cell killing. In contrast, non-cancerous breast epithelial HMEC cells showed reduced survival after MCU or MICU1 knockdown. These results support the conclusion that MDA-MB-231 breast cancer cells do not rely on MCU or MICU1 activity for survival in contrast to previous findings in cells derived from cervical, colon, and

    To determine age-related association of Her-2/neu expression with histological and immunohistochemical prognostic markers in female breast carcinoma. Study Design: Cross sectional, observational study. Place and Duration of Study: Department of Histopathology, Armed Forces Institute of Pathology, Rawalpindi, from January 2004 to December 2007. Methodology: Patients of primary operable female breast carcinoma were categorised as 50 years (post-menopausal) age groups. Histological type, tumour size, tumour grade and lymph node status were determined while estrogen receptor (ER), progesterone receptor (PR) and Her-2/neu expression were evaluated immunohistochemically. Association of Her-2/neu with histological and immunohistochemical prognostic markers was determined in pre-menopausal, peri-menopausal and post- menopausal age groups using the x2 test for uni- and multivariate analysis. Results: Out of the 722 patients, 230 (31.9%) were in pre-menopuasal, 221 (30.6%) in peri-menopausal and 271 (37.5%) in post-menopausal age group. Infiltrating ductal carcinoma was the pre-dominant subtype in all the age groups. Mean tumour size was 4.3 +- 2.3 cm (range 0.4-17 cm) and lymph node metastasis was seen in 310 (70.8%) cases. Her-2/neu showed association with ER in the all the age groups while PR only showed association in the peri-menopausal and postmenopausal women. Her-2/neu showed no association with tumour size, tumor grade and lymph node metastases in pre-menopausal and peri-menopausal women while it showed positive association with tumour size and lymph node metastasis in the post-menopausal women (p < 0.05). Conclusion: Majority (62%) patients were under 50 years as against the Western epidemiology. Association of Her-2/neu with ER, PR, tumour size and lymph node metastasis was age related as pre-menopausal, peri-menopausal and postmenopausal had variable expression of these prognostic markers with therapeutic and prognostic implications.

    2011-11-01

    Full Text Available Abstract Background Diagnosis of ductal carcinoma in situ (DCIS in breast cancer cases is challenging for pathologist due to a variety of in situ patterns and artefacts, which could be misinterpreted as stromal invasion. Microinvasion is detected by the presence of cytologically malignant cells outside the confines of the basement membrane and myoepithelium. When malignant cells invade the stroma, there is tissue remodeling induced by perturbed stromal-epithelial interactions. Carcinoma-associated fibroblasts (CAFs are main cells in the microenvironment of the remodeled tumor-host interface. They are characterized by the expression of the specific fibroblast activation protein-alpha (FAP-α, and differ from that of normal fibroblasts exhibiting an immunophenotype of CD34. We hypothesized that staining for FAP-α may be helpful in determining whether DCIS has microinvasion. Methods 349 excised breast specimens were immunostained for smooth muscle actin SMA, CD34, FAP-α, and Calponin. Study material was divided into 5 groups: group 1: normal mammary tissues of healthy women after plastic surgery; group 2: usual ductal hyperplasia (UDH; group 3: DCIS without microinvasion on H & E stain; group 4: DCIS with microinvasion on H & E stain (DCIS-MI, and group 5: invasive ductal carcinoma (IDC. A comparative evaluation of the four immunostains was conducted. Results Our results demonstrated that using FAP-α and Calponin adjunctively improved the sensitivity of pathological diagnosis of DCIS-MI by 11.29%, whereas the adjunctive use of FAP-α and Calponin improved the sensitivity of pathological diagnosis of DCIS by 13.6%. Conclusions This study provides the first evidence that immunostaining with FAP-α and Calponin can serve as a novel marker for pathologically diagnosing whether DCIS has microinvasion.

    Full Text Available A second malignant neoplasm has been found to be more frequent than might be expected from the general population rates. Therapy-related myelodysplastic syndrome and acute leukemia are dreaded long-term complications of five cases of hematological malignancies following treatment for successful breast cancer therapy (therapeutic drugs or radiotherapy. We encountered carcinoma from north India over a 7-year period from 1999 to 2005. The patients presented 2-5 years after treatment of breast carcinoma. Three patients underwent surgery and received chemoradiotherapy. One patient received chemotherapy after surgery. One patient underwent only surgery and after 3 years presented with acute myeloid leukemia and bone marrow metastasis of carcinoma of the breast. At the time of presentation, all the patients had either bicytopenia or pancytopenia. A close follow-up with complete blood cell counts of the patients who previously had carcinoma of the breast is suggested for early detection of hematological abnormalities. However, the poor prognosis, limited financial resources and poor health insurance coverage results in few patients and their family members opting for treatment.

    Full Text Available Background : Cytological grading (CG on aspirates of breast carcinoma is a useful tool for surgical maneuver and prognosis. Aims : An endeavor was made to use CG on aspirates of breast carcinoma using Robinson′s grade and to correlate it with Bloom Richardsons′ histopathological grading. Materials and Methods : A total of 59 patients of breast carcinoma, aged 28-57 years, were aspirated and the smears were graded using Robinson′s criteria. All the cases were correlated with Bloom Richardson′s grade on histopathology in mastectomy specimens. Lymphadenopathy in 38 cases was aspirated and stained with Papanicolaou and Romanowsky stain. Results : Robinson′s CG correlated well with Bloom Richardson′s histopathological grading. For grade I and II tumors, there was substantial strength of agreement between cytology and histopathology, while in grade III, the concordance was nearly perfect. Lymph node metastasis was found in 27 of 32 axillary nodes, three of five cervical nodes and the only palpable supraclavicular node. Lymph node metastasis was observed in three with cytological grade II, 28 of grade III and none of grade I. All grade I had stage A, two of grade II had stage B, while all grade III had either stage B or stage C disease. Conclusions : Thus, CG of breast carcinoma correlates well with histopathological grading and may well be useful as a prognostic marker.

    Metastases to breast are much rarer than primary breast tumors. We now present a case of 45-year-old female, who presented with an isolated breast mass. A positron emission tomography-computed tomography (PET-CT) done revealed hypermetabolic right breast nodules, soft tissue deposits, and multiple nodal involvement. The biopsy from the breast and axillary lymph node showed dense lymphoid infiltrate and was interpreted initially as granulomatous inflammation. However, the lumps were hard and suspicious for primary breast cancer, so an immunohistochemistry for cytokeratin was performed which highlighted the epithelial cell clusters masked within the inflammatory infiltrate and the diagnosis of undifferentiated carcinoma, lymphoepithelioma-like was made. After the diagnosis was made, it was realized that the patient had been treated earlier for a nasopharyngeal carcinoma (NPC). The in situ hybridization (ISH) test for Epstein-Barr virus-encoded RNA ISH was positive in the tumor cells, and hence, a diagnosis of metastatic NPC was finally made. The patient subsequently developed extensive nodal, skeletal, and soft tissue metastatic disease but was alive till September 2015. Although extremely rare, metastatic NPC can occur in the breast and the above case highlights that it mimics an inflammatory lesion. This case highlights the importance of the multidisciplinary approach for appropriate tumor diagnosis and patient management.

    Full Text Available Metastases to breast are much rarer than primary breast tumors. We now present a case of 45-year-old female, who presented with an isolated breast mass. A positron emission tomography-computed tomography (PET-CT done revealed hypermetabolic right breast nodules, soft tissue deposits, and multiple nodal involvement. The biopsy from the breast and axillary lymph node showed dense lymphoid infiltrate and was interpreted initially as granulomatous inflammation. However, the lumps were hard and suspicious for primary breast cancer, so an immunohistochemistry for cytokeratin was performed which highlighted the epithelial cell clusters masked within the inflammatory infiltrate and the diagnosis of undifferentiated carcinoma, lymphoepithelioma-like was made. After the diagnosis was made, it was realized that the patient had been treated earlier for a nasopharyngeal carcinoma (NPC. The in situ hybridization (ISH test for Epstein–Barr virus-encoded RNA ISH was positive in the tumor cells, and hence, a diagnosis of metastatic NPC was finally made. The patient subsequently developed extensive nodal, skeletal, and soft tissue metastatic disease but was alive till September 2015.

    Invasive lobular carcinoma (ILC) comprises approximately 10% of breast cancers and appears to have a distinct biology. Because it is less common than infiltrating ductal carcinoma (IDC), few data have been reported that address the biologic features of ILC in the context of their clinical outcome. In the present study we undertook an extensive comparison of ILC and IDC using a large database to provide a more complete and reliable assessment of their biologic phenotypes and clinical behaviors. The clinical and biological features of 4140 patients with ILC were compared with those of 45,169 patients with IDC (not otherwise specified). The median follow-up period was 87 months. In comparison with IDC, ILC was significantly more likely to occur in older patients, to be larger in size, to be estrogen and progesterone receptor positive, to have lower S-phase fraction, to be diploid, and to be HER-2, p53, and epidermal growth factor receptor negative. It was more common for ILC than for IDC to metastasize to the gastrointestinal tract and ovary. The incidence of contralateral breast cancer was higher for ILC patients than for IDC patients (20.9% versus 11.2%; P < 0.0001). Breast preservation was modestly less frequent in ILC patients than in IDC patients. The 5-year disease-free survival was 85.7% for ILC and 83.5% for IDC (P = 0.13). The 5-year overall survival was 85.6% for ILC and 84.1% for IDC (P = 0.64). Despite the fact that the biologic phenotype of ILC is quite favorable, these patients do not have better clinical outcomes than do patients with IDC. At present, management decisions should be based on individual patient and tumor biologic characteristics, and not on lobular histology

    5'AMP-activated protein kinase (AMPK) and the mammalian target of rapamycin (mTOR) are two serine/threonine protein kinases responsible for cellular energy homeostasis and translational control, respectively. Evidence suggests that these two kniases are potential targets for cancer chemotherapy against hepatocellular carcinoma (HCC). Antroquinonol that is isolated from Antrodia camphorate, a well-known Traditional Chinese Medicine for treatment of liver diseases, displayed effective anticancer activity against both HBV DNA-positive and -negative HCC cell lines. The rank order of potency against HCCs is HepG2>HepG2.2.15>Mahlavu>PLC/PRF/5>SK-Hep1>Hep3B. Antroquinonol completely abolished cell-cycle progression released from double-thymidine-block synchronization and caused a subsequent apoptosis. The data were supported by down-regulation and reduced nuclear translocation of G1-regulator proteins, including cyclin D1, cyclin E, Cdk4 and Cdk2. Further analysis showed that the mRNA expressions of the G1-regulator proteins were not modified by antroquinonol, indicating an inhibition of translational but not transcriptional levels. Antroquinonol induced the assembly of tuberous sclerosis complex (TSC)-1/TSC2, leading to the blockade of cellular protein synthesis through inhibition of protein phosphorylation including mTOR (Ser(2448)), p70(S6K) (Thr(421)/Ser(424) and Thr(389)) and 4E-BP1 (Thr(37)/Thr(46) and Thr(70)). Furthermore, the AMPK activity was elevated by antroquinonol. Compound C, a selective AMPK inhibitor, significantly reversed antroquinonol-mediated effects suggesting the crucial role of AMPK. Besides, the loss of mitochondrial membrane potential and depletion of mitochondrial content indicated the mitochondrial stress caused by antroquinonol. In summary, the data suggest that antroquinonol displays anticancer activity against HCCs through AMPK activation and inhibition of mTOR translational pathway, leading to G1 arrest of the cell-cycle and subsequent cell

    The locoregional control of 60 to 61 patients supports the results published by other centers and compares favorably with results of any surgical series. The cosmetic results are excellent with only three of 61 patients having severe fibrosis of the breast develop. No rib fractures, skin ulcerations, symptomatic radiation pneumonitis, edema of the arm or limitation of arm movement have been observed as complications. Ten of the 28 patients who have had axillary dissection had transient edema of the breast develop. Results of numerous studies suggest that primary radiotherapy without mastectomy is appropriate treatment for early carcinoma of the breast. The accessibility of the breast makes it relatively easy to deliver curative doses of radiation with minimal damage to surrounding normal tissues. The cumulative radiotherapy experience has demonstrated the gratifying results of not only maintaining a rather normal breast but also avoiding the negative physical and psychologic repercussions of the mastectomy. Radiation therapy is an alternative to Halsted's radical mastectomy

    Our study was done to assess the cytological changes due to oncotherapy in breast carcinoma especially on morphometry and proliferative activity. Cytological aspirates were collected from a total of 32 cases of invasive ductal carcinoma both before and after oncotherapy. Morphometry was done on the stained cytological smears to assess the different morphological parameters of cell dimension by using the ocular morphometer and the software AutoCAD 2007. Staining was done with Ki-67 and proliferating cell nuclear antigen (PCNA) as proliferative markers. Different morphological parameters were compared before and after oncotherapy by unpaired Student's t test. Statistically significant differences were found in morphometric parameters, e.g., mean nuclear diameter, mean nuclear area, mean cell diameter, and mean cell area, and in the expression of proliferative markers (Ki-67 and PCNA). Statistical analysis was done by obtaining p values. There are statistically significant differences between morphological parameter of breast carcinoma cells before and after oncotherapy.

    Metaplastic carcinoma of the breast (MCB) is a rare form of cancer containing mixture of epithelial and mesenchymal elements in variable combinations. Few and conflicting clinical data are available in the literature addressing optimal treatment modalities, prognosis and outcome. A retrospective study was conducted to review all patients with MCB diagnosed and treated at Breast Unit of Azienda Ospedaliera "Santa Maria" Terni - Italy between 2001/2010. The aim is to describe patient's clinic pathologic features and to analyze treatment results. Six female patients were studied. The median age was 48 years (range 14/58). The median tumor size was 9 cm. (range 3/18 cm.). Two cases (33%) were identified as purely epithelial and 4 (67%) as mixed epithelial and mesenchymal metaplasia. Hormone receptors were positive in only 2 patients. Modified radical mastectomy performed in 3 patients and 5 underwent axillary node dissection. Adjuvant chemotherapy was given to all patients and postoperative radiotherapy to 4. Four patients relapsed with median time of relapse of 12 months. MCB is an aggressive form of breast cancer associated with poor outcome, high incidence of local recurrence and pulmonary metastases. The disease tends to be estrogen/progesterone receptor negative. Tumor size has an important impact on outcome. The best treatment approach is yet to be defined.

    Breast cancer is the most common malignant neoplastic process and the second cause of death for women. Ovarian cancer, despite having a lower incidence, represents an important cause of morbidity and mortality because it is usually discovered in advanced stages. The presence of both forms of cancer in a patient is associated with a high risk of BRCA1 gene mutations, which are responsible, together with BRCA2 gene mutations, for most of the breast and ovarian cancer family. Our case is special because it presents a synchronous and a rare association of a primary ovarian dysgerminoma (with an incidence of less than 1% of ovarian cancers) and a primary breast carcinoma in a patient of 46 years old. Immunohistochemical examination was performed using a panel of five biomarkers: oestrogen receptor, progesterone receptor, Herceptest, p53 and BRCA1. In our case, we identified a negative hormonal status and the absence of HER2/neu expression but a positive immuno-expression for p53 protein and BRCA1 protein. Postoperative course was favourable for the patient after each surgery, and she was discharged with the recommendation to perform a genetic counselling. Celsius.

    Compromised patterns of gene expression result in genomic instability, altered patterns of gene expression and tumour formation. Specifically, aberrant DNA hypermethylation in gene promoter regions leads to gene silencing, whereas global hypomethylation events can result in chromosomal instability and oncogene activation. Potential links exist between environmental agents and DNA methylation, but the destabilizing effects of environmental exposures on the DNA methylation machinery are not understood within the context of breast cancer aetiology. We assessed genome-wide changes in methylation patterns using a unique methylation profiling technique called amplification of intermethylated sites (AIMS). This method generates easily readable fingerprints that represent the investigated cell line's methylation profile, based on the differential cleavage of DNA with methylation-specific isoschisomeric restriction endonucleases. We validated this approach by demonstrating both unique and reoccurring sites of genomic hypomethylation in four breast carcinoma cell lines treated with the cytosine analogue 5-azacytidine. Comparison of treated with control samples revealed individual bands that exhibited methylation changes, and these bands were excized and cloned, and the precise genomic location individually identified. In most cases, these regions of hypomethylation coincided with susceptible target regions previously associated with chromosome breakage, rearrangement and gene amplification. Similarly, we observed that acute benzopyrene exposure is associated with altered methylation patterns in these cell lines. These results reinforce the link between environmental exposures, DNA methylation and breast cancer, and support a role for AIMS as a rapid, affordable screening method to identify environmentally induced DNA methylation changes that occur in tumourigenesis

    Full Text Available It has been well established that estrogen plays an important role in the progression and treatment of breast cancer. However, the role of triiodothyronine (T3 remains controversial. We have previously shown its capacity to stimulate the development of positive estrogen receptor breast carcinoma, induce the expression of genes (PR, TGF-alpha normally stimulated by estradiol (E2, and suppress genes (TGF-beta normally inhibited by E2. Since T3 regulates growth hormones, metabolism, and differentiation, it is important to verify its action on other genes normally induced by E2. Therefore, we used DNA microarrays to compare gene expression patterns in MCF-7 breast adenocarcinoma cells treated with E2 and T3. Several genes were modulated by both E2 and T3 in MCF-7 cells (Student’s t-test, P 2.0, pFDR < 0.05. We confirmed our microarray results by real-time PCR. Our findings reveal that certain genes in MCF-7 cells can be regulated by both E2 and T3.

    The aim of our study was to establish which clinical, radiologic and pathologic factors could predict the risk of under- and overestimation of the breast ductal carcinoma in situ (DCIS) size when preoperatively measuring the maximum mammographic extent of microcalcifications (MEM). We made a retrospective review of patients with a DCIS treated in our Breast Unit between May 2005 and May 2012. Clinical, pathologic and radiologic data were evaluated as possible predictive factors for over- or underestimation of DCIS size when measuring MEM. We obtained precise measurements of MEM in 82 patients (84 DCIS lesions). Maximum MEM measurement correctly estimated maximum pathology size in 57 lesions (68.7 %). Patients with a correctly estimated DCIS, with an underestimated DCIS and with an overestimated DCIS significantly differed in DCIS ER expression (p = 0.022) and in maximum MEM measurement (p = 0.000). Constructing two ROC curves, we found that a maximum MEM measurement ≥25 mm and ER expression ≥90 % were both discrimination points for overestimation and ER ≤ 45 % was a discrimination point for underestimation. Using these cutoff points, we defined four groups of patients with different risks of over- and underestimation. Risk of over- or underestimation of DCIS size through MEM measurement depends on DCIS ER expression and MEM itself. Identifying which patients are at a significant risk of over- or underestimation could help the breast surgeon when discussing the surgical options with the patient.

    The present study comprises 847 women operated upon for invasive breast carcinoma at 19 surgical departments and enrolled in protocol DBCG-82TM from January 1983 to November 1987. Among them 662 (78%) were allocated for breast-preserving therapy or mastectomy by randomization, while 185 patients (22%) did not accept randomization. Within the randomized group 6% could not be entered into adjuvant protocols, i.e. subsequent programmes of postoperative therapy and follow-up. This left 619 evaluable patients. In the non-randomized series 26% did not fulfil the demands for entrance into the adjuvant protocols, leaving 136 evaluable patients, 60 of whom had chosen a breast-preserving operation and 76 mastectomy. In the randomized series the patients in the two treatment arms were comparable in age, menopausal status, site of tumour, pathoanatomical diameter of the tumour, number of removed axillary lymph nodes, number of metastatic axillary lymph nodes, and distribution on adjuvant regimens. Ninety per cent of the patients in the randomized group accepted the method offered, whereas 10% declined and wanted the alternate form of operation. The median follow-up period was approximately 1.75 years. The cumulative recurrence rate in the randomized group was 13% and in the non-randomized group 7%. These results are preliminary. Life-table analyses have not so far demonstrated differences in recurrence-free survival either in the randomized or the non-randomized series. (orig.)

    Laparoscopic cholecystectomy and an excision of the left breast mass were performed. The breast mass was pathologically confirmed to be infiltrating ductal carcinoma not otherwise specified and with predominantly cystic degeneration. The patient received chemotherapy with tamoxifen for the breast cancer, and transarterial chemoembolization for the HCC. Concomitant breast cancer and HCC in a male patient were rarely reported in the literature. Herein, we have discussed the possible relationship of these two disease entities.

    Polarization imaging has been recognized as a potentially powerful technique for probing the microstructural information and optical properties of complex biological specimens. Recently, we have reported a Mueller matrix microscope by adding the polarization state generator and analyzer (PSG and PSA) to a commercial transmission-light microscope, and applied it to differentiate human liver and cervical cancerous tissues with fibrosis. In this paper, we apply the Mueller matrix microscope for quantitative detection of human breast ductal carcinoma samples at different stages. The Mueller matrix polar decomposition and transformation parameters of the breast ductal tissues in different regions and at different stages are calculated and analyzed. For more quantitative comparisons, several widely-used image texture feature parameters are also calculated to characterize the difference in the polarimetric images. The experimental results indicate that the Mueller matrix microscope and the polarization parameters can facilitate the quantitative detection of breast ductal carcinoma tissues at different stages.

    Full Text Available Breast cancer estrogen receptor (ER status is one of the strong additional factors in predicting response of patients towards hormonal treatment. The main aim of this study was to assess the morphological characteristics and proliferative activity using MIB-1(Ki-67 of estrogen receptor negative invasive breast ductal carcinoma (NOS type as well as to correlate these features with clinicopathological data. We also aim to study the expression of c-erbB2 in ER negative breast tumors. High proliferative rate (MIB-1 above 20% was observed in 63 (63.6% of 99 ER negative tumors and that these tumors were associated with high expression of c-erbB2 (57.6%. We observed that MIB-1 is a reliable independent prognostic indicator for ER negative infiltrating ductal carcinoma in this study.

    Invasive lobular carcinoma (ILC) accounts for approximately 10% of all breast carcinomas and is characterized by higher levels of androgen receptor (AR) compared to invasive ductal carcinoma (IDC). Despite this potentially androgen-responsive environment, the combined importance of AR and androgen metabolism in non-neoplastic lobules and lobular carcinoma remains unknown. Therefore, in this study, we evaluated the status of pivotal androgen-producing enzymes 17β-hydroxysteroid dehydrogenase type 5 (17βHSD5) and 5α-reductase type 1 (5αRed1) in 178 cases of ILC and surrounding histologically non-neoplastic lobular tissue using immunohistochemistry. Androgen receptor prevalence was higher but androgenic enzymes lower in ILC than non-neoplastic lobules. In ILC cases the status of 5αRed1 and 17βHSD5 was inversely correlated with tumor size (P = 0.0053) and nuclear grade (P = 0.0290), and significantly associated with better overall survival of the patients (P = 0.0059). Based on these findings, we hypothesized that androgen signaling could act as a tumor suppressor. As previous studies suggested that androgens might partially act by increasing levels of the estrogen inactivating enzyme 17β-hydroxysteroid dehydrogenase type 2 (17βHSD2) in IDC tissues, this was reasonably considered a potential mechanism of androgen actions. Significantly positive correlation was detected between the status of androgenic enzymes and 17βHSD2 (P Cancer Science published by Wiley Publishing Asia Pty Ltd on behalf of Japanese Cancer Association.

    Magnetic resonance imaging (MRI) is highly sensitive in detecting invasive lobular carcinoma (ILC) of the breast. In our institution, patients who are deemed to be suitable for breast conserving surgery (BCS) with unifocal small ILC on standard imaging are offered breast MRI to exclude multifocal and larger ILC. Our study investigates the usefulness of breast MRI in ILC. A prospective cohort study over a 58-month period, including all consecutive patients with ILC having breast MRI. Primary objective was to find out the proportion of ILC patients where preoperative MRI caused a change in the surgical treatment. Secondary objectives included finding mastectomy rate (initial & final), re-operation rate, cancer size correlation with different imaging modalities and final histopathology, loco-regional recurrence and disease-free survival. A total of 334 bilateral breast MRI were performed including 72 (21.5%) MRI for ILC patients. All these MRI were carried out within 2 week of patients given the diagnosis (median 5.5 days). Age range was 24-83 (median 56.5) years. Nineteen of 72 ILC patients (26.4%) had a change in their planned operation from BCS to a different operation owing to MRI findings (seven patients with multifocal cancers, 10 with significantly larger size of the cancer and two with contralateral malignancy). Initial mastectomy rate was 31.9%, final mastectomy rate was 36.1% and re-operation rate in BCS group was 18.3%. MRI correlated better with ILC histopathology cancer size than mammogram and ultrasound scans. There was no statistically significant difference (p = 0.999) between the cancer size on histology (median 23 mm) and MRI (median 25 mm). However, mammogram (median 17 mm) and ultrasound (median 14.5 mm) scans showed cancer sizes significantly different to final histology cancer size (p = 0.0008 and p = 0.0021 respectively). Over a 44 months median follow-up (range 27-85), 95.8% disease-free survival and 98.6% overall survival have been observed

    2016-02-01

    There is evidence from the literature that the terms "ductal carcinoma in situ" and "lobular carcinoma in situ" (DCIS and LCIS) should be eliminated in clinical breast cancer practice and replaced with the new "ductal intraepithelial neoplasia" (DIN) and "lobular intraepithelial neoplasia" (LIN) terminology. The main purpose of the present article is to expand on this argument from a cognitive psychology perspective and offer suggestions for further research, emphasizing how the elimination of the term "carcinoma" in "in situ" breast cancer diagnoses has the potential to reduce both patient and health care professional confusion and misperceptions that are often associated with the DCIS and LCIS diagnoses, as well as limit the adverse psychological effects of women receiving a DCIS or LCIS diagnosis. We comment on the recent peer-reviewed literature on the clinical implications and psychological consequences for breast cancer patients receiving a DCIS or LCIS diagnosis and we use a cognitive perspective to offer new insight into the benefits of embracing the new DIN and LIN terminology. Using cognitive psychology and cognitive science in general, as a foundation, further research is advocated in order to yield data in support of changing the terminology and therefore, offer a chance to significantly improve the lives and psychological sequelae of women facing such a diagnosis.

    Breast cancer is a heterogeneous disease with different molecular subtypes that have varying responses to therapy. An ongoing challenge in breast cancer research is to distinguish high-risk patients from good prognosis patients. This is particularly difficult in the low-grade, ER-positive luminal A tumors, where robust diagnostic tools to aid clinical treatment decisions are lacking. Recent data implicating chromatin regulators in cancer initiation and progression offers a promising avenue to develop new tools to help guide clinical decisions. Here we exploit a published transcriptome dataset and an independent validation cohort to correlate the mRNA expression of selected chromatin regulators with respect to the four intrinsic breast cancer molecular subtypes. We then perform univariate and multivariate analyses to compare the prognostic value of a panel of chromatin regulators to Ki67, a currently utilized proliferation marker. Unsupervised hierarchical clustering revealed a gene cluster containing several histone chaperones and histone variants highly-expressed in the proliferative subtypes (basal-like, HER2-positive, luminal B) but not in the luminal A subtype. Several chromatin regulators, including the histone chaperones CAF-1 (subunits p150 and p60), ASF1b, and HJURP, and the centromeric histone variant CENP-A, associated with local and metastatic relapse and poor patient outcome. Importantly, we find that HJURP can discriminate favorable and unfavorable outcome within the luminal A subtype, outperforming the currently utilized proliferation marker Ki67, as an independent prognostic marker for luminal A patients. The integration of chromatin regulators as clinical biomarkers, in particular the histone chaperone HJURP, will help guide patient substratification and treatment options for low-risk luminal A breast carcinoma patients.

    Full Text Available Breast cancer is one of the most devastating cancers afflicting women, being a main cause of cancer related death. Approximately 50% of these patients have developed regional or distant metastases at the time of diagnosis; hence, an early diagnosis and surgery with indicated neoadjuvant therapy are crucial in eradicating this disease and improving patient survival. A significant percentage of patients, even after initial satisfactory tumor removal, still face the threat of metastatic diseases which could plague a wide spectrum of body sites such as bones, lungs, central nervous system, liver and gastrointestinal tract (mostly upper gastrointestinal locations. Colonic and anorectal involvement by metastatic breast cancer has been less frequently reported in disseminated diseases. Typically, metastatic disease presents as a mass, enteric stenosis, or obstruction. Rare cases, however, may not form an endoscopically or radiologically recognizable lesion, and thus could be overlooked. Here we report a unique case of random colon biopsies in a patient presenting with epigastric pain, whose stomach biopsy showed Helicobacter pylori-associated chronic active gastritis. No colonoscopic lesion was present; however, microscopic examination of the “random biopsy” revealed scattered single and small clusters of tumor cells involving the lamina propria of the colonic mucosa, morphologically and immunophenotypically consistent with metastatic disease from breast carcinoma. The clinical presentation and histopathology of the case were reviewed and compared with limited cases reported in the literature. We conclude that high levels of suspicion and alertness are essential to identify occult microscopic gastrointestinal metastatic breast cancer in the absence of a grossly appreciable lesion.

  19. Expression analysis of carbohydrate antigens in ductal carcinoma in situ of the breast by lectin histochemistry

    Full Text Available Abstract Background The number of breast cancer patients diagnosed with ductal carcinoma in situ (DCIS continues to grow. Laboratory and clinical data indicate that DCIS can progress to invasive disease. Carbohydrate-mediated cell-cell adhesion and tumor-stroma interaction play crucial roles in tumorigenesis and tumor aggressive behavior. Breast carcinogenesis may reflect quantitative as well as qualitative changes in oligosaccharide expression, which may provide a useful tool for early detection of breast cancer. Because tumor-associated carbohydrate antigens (TACA are implicated in tumor invasion and metastasis, the purpose of this study was to assess the expression of selected TACA by lectin histochemistry on DCIS specimens from the archival breast cancer tissue array bank of the University of Arkansas for Medical Sciences. Methods For detection of TACA expression, specimens were stained with Griffonia simplicifolia lectin-I (GS-I and Vicia vilosa agglutinin (VVA. We studied associations of lectin reactivity with established prognostic factors, such as tumor size, tumor nuclear grade, and expression of Her-2/neu, p53 mutant and estrogen and progesterone receptors. Results We observed that both lectins showed significant associations with nuclear grade of DCIS. DCIS specimens with nuclear grades II and III showed significantly more intense reactivity than DCIS cases with nuclear grade I to GS-1 (Mean-score chi-square = 17.60, DF = 2; P = 0.0002 and VVA (Mean-score chi-square = 15.72, DF = 2; P = 0.0004. Conclusion The results suggest that the expression of VVA- and GS-I-reactive carbohydrate antigens may contribute to forming higher grade DCIS and increase the recurrence risk.

    Since October 1976, the treatment policy in our Radiotheapy Center for Stage I carcinoma of the breast has been excision of the tumor mass, when it was cosmetically suitable, followed by irradiation to the breast and periphereal lymphatics. Eighty-three patients were admitted between October 1976 and March 1980. They underwent local excision of the tumor and then received 5000 rad in 5 weeks to the breast, supraclavicular, axillary and internal mammary chain lymph nodes. Each field was treated every day. A boost was then given to the scar, bringing the dose up to 6500 rad, calculated at maximum tumor depth, depending upon the size of the tumor prior to surgery. Cosmetic results were quite good, and the local control rate at 54 months is 98%. The survival with no evidence of disease (NED) at 54 months (actuarial) is 83%. Twenty-one out of 83 patients have had complications (25.3%); of these, 28.8% were surgical and the remainder results from radiotherapy after surgery, either from radiotherapy alone or from combination of treatments. Of the total of 21 complications, 18 were mild and 3 were serious.These results compare favorably with the results achieved in the same Hospital with radical surgery as far as local tumor control and survival with no evidence of disease (NED) is concerned. The results also compared with the great majority of surgical series reported in the literature, allowing us to conclude that patients treated with radiation have nothing to lose and much to gain by preserving the breast

    Invasive lobular carcinomas (ILC) represent the most common subtype of invasive breast cancer and account for about 5-15% of all breast cancer cases. Invasive lobular carcinoma is often accompanied by in situ lesions, by lobular neoplasia (LN). Invasive lobular carcinomas display diverse histologic patterns varying from classical through solid to pleomorphic subtypes. When analyzing histological subtypes, the classical variant is reported to have a more favorable outcome. The majority of inva...

    Over the last three years 30,000 mammograms were performed in the Department of Diagnostic Imaging of Universidade Federal de Sao Paulo/Escola Paulista de Medicina. Accessory breast tissue was observed in 0.23% of the individuals. We report a case of a 44-year-old woman presenting a hard nodule adhered to the subcutaneous tissue in right inframammary topography. At ultrasonography, a hypoechogenic solid nodule with irregular contour measuring 1.4 cm was observed. Magnetic resonance imaging showed type II (plateau) dynamic curve. Breast adenocarcinoma was subsequently diagnosed by biopsy. Accessory breast carcinomas generally present with an ill-defined histopathological aspect and early dissemination. Early detection is essential to begin treatment in the initial stages, with better chances of cure. (author)

    Micropapillary carcinoma (MPC) is a rare histological special type of breast cancer, characterized by an aggressive clinical behaviour and a pattern of copy number aberrations (CNAs) distinct from that of grade- and oestrogen receptor (ER)-matched invasive carcinomas of no special type (IC-NSTs). The aims of this study were to determine whether MPCs are underpinned by a recurrent fusion gene(s) or mutations in 273 genes recurrently mutated in breast cancer. Sixteen MPCs were subjected to microarray-based comparative genomic hybridization (aCGH) analysis and Sequenom OncoCarta mutation analysis. Eight and five MPCs were subjected to targeted capture and RNA sequencing, respectively. aCGH analysis confirmed our previous observations about the repertoire of CNAs of MPCs. Sequencing analysis revealed a spectrum of mutations similar to those of luminal B IC-NSTs, and recurrent mutations affecting mitogen-activated protein kinase family genes and NBPF10. RNA-sequencing analysis identified 17 high-confidence fusion genes, eight of which were validated and two of which were in-frame. No recurrent fusions were identified in an independent series of MPCs and IC-NSTs. Forced expression of in-frame fusion genes (SLC2A1-FAF1 and BCAS4-AURKA) resulted in increased viability of breast cancer cells. In addition, genomic disruption of CDK12 caused by out-of-frame rearrangements was found in one MPC and in 13% of HER2-positive breast cancers, identified through a re-analysis of publicly available massively parallel sequencing data. In vitro analyses revealed that CDK12 gene disruption results in sensitivity to PARP inhibition, and forced expression of wild-type CDK12 in a CDK12-null cell line model resulted in relative resistance to PARP inhibition. Our findings demonstrate that MPCs are neither defined by highly recurrent mutations in the 273 genes tested, nor
