Objective: The aim of this study was to examine the expression of matriptase and survivin in breast carcinoma and correlate with clinicopathological parameters.Methods: Immunohistochemical analysis of matriptase and survivin were performed in tissue microarray slides of 290 cases, including 11 normal breast tissue; 27 fibrocystic disease; 17 fibroadenoma; 6 atypical ductal hyperplasia; 39 ductal carcinoma in situ, low grade (DCIS, low grade); 39 ductal carcinoma in situ, high grade (DCIS, high grade); 27 invasive ductal carcinoma, grade I (IDC, grade I); 78 invasive ductal carcinoma, grade II (IDC, grade II); and 46 invasive ductal carcinoma, grade III (IDC, grade III).Results: The average immunostaining scores of matriptase were 44.1 in normal breast tissue, 52.7 in fibrocystic disease, 76.5 in fibroadenoma, 81.7 in atypical ductal hyperplasia, 133.7 in low-grade DCIS, and 155.8 in high-grade DCIS. Among 151 breast IDC cases, the average immunostaining scores of matriptase were 172.7 in grade I, 211.7 in grade II, and 221.2 in grade III. Additionally, the average immunostaining scores of surviving also correlate with tumor grades and stages.Conclusions: Higher expressions of matriptase and survivin correlate significantly with clinicopathological parameters in breast cancer and the malignant potential in premalignant lesions. In addition, higher survivin expression had poorer prognosis of breast IDC cases.

One hundred cases of histologically proven invasive ductal carcinomas were histologically graded based on modified Bloom and Richardson Grading. Out of these 17 cases each of low grade, intermediate grade, and high grade invasive ductal carcinomas were selected for Immunostaining using the monoclonal antibodies Cyclin D1,pP53 and Her2/neu. It was found that for all three monoclonal antibodies the lowest histological grade of Invasive Ductal Carcinoma of the Breast showed the lowest positivity with Cyclin D1 ( 11.76%) and p53 ( 17.64%) and Her2/neu ( 47.05%). The intermediate grade tumour showed ( 70.58% ) positivity with Cyclin D1 and 58.58 % in p53 and Her2/neu. The high grade invasive ductal carcinoma of the breast showed the highest positivity of Cyclin D1 (76.47%) , p53 (88.24% ) ,Her2/neu ( 94.12% ); These suggest that Cyclin D1 , P53 and Her2/neuimmunoexpression positivity increases with rising histological grades of invasive ductal carcinoma of breast.

Ductal Hyperplasia

This is the case of a 44-year-old woman with a one-year history of a left pre-auricular mass. The surgical specimen is a 5 centimeter diameter tan-brown irregularly-shaped tissue whose cut surfaces are brown with cystic spaces. Microscopic sections show cystic and dilated ductal spaces lined by cells forming irregular, variably-sized secondary spaces. These spaces are arranged in a cribriform pattern that is reminiscent of breast ductal hyperplasia. (Figure 1) The ductal cells lining the spaces are small, multilayered, and generally bland. The superficial cells show apocrine-type cytoplasmic snouting. There is no significant nuclear atypia or mitotic activity noted. Necrosis is also absent. (Figure 2) Based on these features, we signed the case as a low-grade cribriform cyastadenocarcinoma (LGCCC).   LGCCC is an uncommon tumor presenting primarily as cystic parotid masses in elderly females. The histologic hallmark of this tumor is its morphologic resemblance to the spectrum of breast lesions ranging from ductal hyperplasia to low-grade ductal carcinoma-in-situ.1-4               Microscopic sections show an unencapsulated tumor consisting of single or multiple cysts lined by proliferated small and bland ductal cells with fine chromatin and small nucleoli. Within the cystic spaces, the cells are often arranged in a cribriform pattern with anastomosing intracystic micropapillae lining the cavity. Many superficial cells show apocrine-type secretions. Thus, the over-all appearance is quite comparable to breast lesions that are termed atypical ductal hyperplasia and low-grade ductal carcinoma-in-situ.1-4 Focal invasion into the surrounding tissue can be seen. Perineural or vascular invasion however is typically absent. Cellular pleomorphism and mitoses are also usually absent and necrosis is rare. Occasional tumors however may demonstrate a transition to an intermediate or high-grade cytology with the appearance of scattered mitoses and focal necrosis.1,2               This tumor needs to be distinguished from a conventional cystadenocarcinoma. The latter is a more frankly invasive tumor with smaller duct-like structures that infiltrate into the salivary parenchyma and surrounding connective tissue. A papillary-cystic variant of acinic cell carcinoma will have areas of acinar differentiation and a greater degree of epithelial proliferation.1,5 A high-grade salivary duct carcinoma will have a high-grade cytology with more frequent necrosis, mitoses, and pleomorphism.6 Special stains that help in the differential diagnosis include Periodic Acid-Schiff (PAS) stain with Diastase digestion (diastase-resistant cytoplasmic granules in an acinic cell carcinoma), and S100 (strong diffuse positivity in LGCCC).1               LGCCC is treated by complete surgical excision. Although there are only a few reported cases with follow-up, to our knowledge, none, to date, have recurred.1-4

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

Abstract Purpose The aim of the study was to evaluate the role of pseudo-continuous ASL-perfusion (pCASL-perfusion) in preoperative assessing of cerebral glioma grades. Methods The study group consisted of 253 patients aged 7 to 78 years with supratentorial gliomas (65 had low-grade gliomas (LGG), 188 – high-grade gliomas (HGG)). Maximal tumor blood flow (maxTBF) in small ROIs (20 mm2 ± 10 mm2) were evaluated by subsequently normalized tumor blood flow (nTBF) calculation which was compared with normal appearing white matter of center semiovale of the contralateral hemisphere. Results TBF and nTBF values were significantly differed in HGG and LGG groups, as well as grade II and grade III gliomas; grade III and grade IV gliomas (p < 0.001). ASL-perfusion has demonstrated both high sensitivity and specificity in differentiating LGG and HGG, grade II and grade III gliomas, but low sensitivity and specificity in distinguishing grade III and grade IV gliomas. We did not observe a significant difference in TBF in astrocytomas and oligodendrogliomas. Conclusion Current results demonstrate that 3D pCASL-perfusion is an effective diagnostic tool for preoperative differentiation of low and high grade gliomas.

Background: Breast cancer is one of the most common cancers among women in India. Stroma has an important role in the pathogenesis of carcinoma of breast. Stromal marker can be novel marker for assessing the prognosis of breast cancer.Methods: With the representative sections of 30 invasive ductal carcinoma of breast NOS type Hematoxylin and eosin staining was done. Immunohistochemistry was done with CD10. CD10 expression in stroma in cases and control slides were studied and statistically analyzed with histopathological grade.Results: 46% (14 out of 30) of cases showed strong positivity for stromal CD10. Only two cases of strong positivity for CD10 were noted in the adjacent normal breast parenchyma. Stromal expression of CD10 had a statistically significant association with breast carcinoma than in control slides, p value is 0.002. 77% (10 out of 13) of CD10 positive cases were high grade carcinomas. Association of CD10 expression with high grade tumour was statistically significant (p value is 0.04 which is less than 0.05). No association was found with mean age.Conclusions: As the grade of breast carcinoma increases the stromal expression of CD10 is increased. Stromal CD10 expression is directly correlated with higher tumour grade. CD10 could be used as novel prognostic marker and used to develop newer drugs.

Neurological tumours are categorized by the WHO as follows: neuroepithelial tumours (gliomas, oligodendrogliomas, ependymomas, pineal parenchymal tumours, medulloblastoma, neuronal and neuroglial tumours); cranial and paraspinal nerve tumours (schwannoma, neurofibromas); meningeal tumours (meningiomas); lymphomas; germ cell tumours (germinoma, teratoma); sellar region tumours (cranipharyngioma); and metastases. The tumours are classified according to grade. The WHO histological grading scheme used for astrocytomas is based on mitoses, nuclear pleomorphism, necrosis, and endothelial proliferation. WHO Grade I and Grade II tumours are low-grade tumours, and WHO Grade III and Grade IV tumours are high-grade tumours.

The literature shows a wide range in the frequencies of finding breast carcinoma in the excised specimens following a biopsy diagnosis of atypical ductal hyperplasia (ADH), likely due to a poor diagnostic reproducibility among different pathologists as well as an inherent heterogeneity in ADH. We evaluated whether histologic subtyping of ADH would help predict the risk of breast carcinoma. Our study consisted of 143 cases of ADH diagnosed by core needle biopsy and followed by excision. Of these, 54 cases (37.8%) showed carcinoma in the excised specimens (47 cases of ductal carcinoma in situ alone, 3 cases of invasive ductal carcinoma alone, and 4 cases of mixed invasive ductal carcinoma and ductal carcinoma in situ). We arbitrarily divided ADH into two subtypes: type A was considered when one or more ducts were completely replaced by low-grade ductal carcinoma in situ type cells but the lesion was <2 mm and type B was considered when one or more ducts were partially involved by low-grade ductal carcinoma in situ type cells regardless of lesion size. Type A was associated with a significantly higher frequency of breast carcinoma (63.6%) than type B (30.0%). ADH containing punctate necrosis showed a higher association of carcinoma (66.7%) compared to those without necrosis (35.1%). Within type B ADH, involvement of 3 or more foci had a higher frequency of carcinoma (50.0%) than involvement of fewer foci (26.6%). These histologic features of ADH may prove useful in predicting the likelihood of breast carcinoma and provide helpful information for patient's management.

Objective: The aim of the present study was to build protein profiles of untreated breast cancer patients of invasive ductal carcinoma grade II at tissue level in Pakistani population and to compare 2-D profiles of breast tumor tissues with matched normal tissues in order to evaluate for variations of proteins among them. Materials & Methods: Breast tissue profiles were made after polytron tissue lysis and rehydrated proteins were further characterized by using two-dimensional gel electrophoresis. On the basis of isoelectric point (pI) and molecular weight, proteins were identified by online tool named Siena 2-D database and their identification was further confirmed by using MALDI-TOF. Results: Among identified spots, 10 proteins were found to be differentially expressed i.e.; COX5A, THIO, TCTP, HPT, SODC, PPIA, calreticulin (CRT), HBB, albumin and serotransferrin. For further investigation, CRT was selected. The level of CRT in tumors was found to be significantly higher than in normal group (p < 0.05). The increased expression of CRT level in tumor was statistically significant (p = 0.010) at a 95% confidence level (p < 0.05) as analyzed by Mann-Whitney. CRT was found distinctly expressed in high amount in tumor tissue as compared to their matched normal tissues. Conclusion: It has been concluded that CRT expression could discriminate between normal tissue and tumor tissue so it might serve as a possible candidate for future studies in cancer diagnostic markers.

Canine cutaneous mast cell tumors (ccMCTs) are currently graded according to Patnaik and Kiupel grading schemes. The qualitative and semiquantitative parameters applied in these schemes may lead to inter- and intraobserver variability. This study investigates the prognostic value of volume-weighted mean nuclear volume ([Formula: see text]), a stereological estimation that provides information about nuclear size and its variability. [Formula: see text] of 55 ccMCTs was estimated using the “point-sampled intercept” method and compared with histological grade and clinical outcome. The clinical history of dogs treated with surgical excision alone was available for 30 ccMCTs. Statistical differences in [Formula: see text] were found between grade II ([Formula: see text]= 115 ± 29 µm3) and grade III ccMCTs ([Formula: see text]= 197 ± 63 µm3), as well as between low-grade ([Formula: see text]= 113 ± 28 µm3) and high-grade ccMCTs ([Formula: see text]= 184 ± 63 µm3). An optimal cutoff value of [Formula: see text] ≥ 150 µm3 and [Formula: see text] ≥ 140 µm3 was determined for grade III and high-grade ccMCTs, respectively. In terms of prognosis, [Formula: see text] was not able to predict the clinical outcome in 42% of the cases; however, cases with [Formula: see text]<125 µm3 had a favorable outcome. These results indicate that, despite having limited prognostic value when used as a solitary parameter, [Formula: see text] is highly reproducible and is associated with histological grade as well as with benign behavior.
