G2 ductal infiltrating carcinomas are a heterogeneous group of tumours with ambiguous clinical significance. This is because G2 carcinomas are almost always the largest category and poorly reproducible. Mitotic count (MC) is one of the causes of poor histological grading reproducibility. The phosphoistone H3 (PPH3) antibody improves identification of mitotic figures. The aim of our study is to demonstrate whether using a new histological grading system based on PPH3 immunostaining to assess MC can re-stratify G2 category...

BACKGROUND: Tumour infiltrating lymphocytes are an important component of the immune response to cancer and have a prognostic value in breast cancer. Although several studies have investigated the role of T-lymphocytes in breast cancer, the role of B lymphocytes (TIL-Bs) in Ductal carcinoma in situ (DCIS), remains uncertain. This study aimed to assess the role of TIL-Bs in DCIS. METHODS: 80 DCIS cases (36 pure DCIS and 44 mixed with invasive cancer) were immunohistochemically stained for B lineage markers CD19, CD20 and the plasma cell marker CD138...

Casting-type calcifications and a histopathological picture with cancer-filled duct-like structures have been presented as breast cancer with neoductgenesis. We correlated mammographic features and histopathological neoductgenesis with prognosis in a DCIS cohort with long follow-up. Mammographic features were classified into seven groups according to Tabár. Histopathological neoductgenesis was defined by concentration of ducts, lymphocyte infiltration, and periductal fibrosis. Endpoints were ipsilateral (IBE) in situ and invasive events...

BACKGROUND: It is desirable to decrease the underestimation rate of invasion in cases diagnosed as ductal carcinoma in situ (DCIS) in breast core needle biopsy (CNB) in order to determine the appropriate candidates for axillary staging. The objective of this study is to identify the predictors of invasion in histology. METHODS AND RESULTS: Consecutive 92 CNB's were retrospectively evaluated. The upstaging rate was 47.8% after surgery. Among all the evaluated parameters, high nuclear grade, single architectural pattern, marked periductal lymphocytic infiltration, partial myoepithelial loss and the presence of foci suspicious of microinvasion were the significant predictors of invasion (two tailed p values 0...

The precise role of interleukin (IL)-10 in breast cancer is not clear. Previous studies suggested a tumor-promoting role of IL-10 in breast cancer, whereas recent discoveries that IL-10 activated and expanded tumor-resident CD8(+) T cells challenged the traditional view. Here, we investigated the role of IL-10 in HLA-A2-positive breast cancer patients with Grade III, Stage IIA or IIB in-situ and invasive ductal carcinoma, and compared it with that of IL-2, the canonical CD8(+) T cell growth factor. We first observed that breast cancer patients presented higher serum levels of IL-2 and IL-10 than healthy controls...

INTRODUCTION: Breast carcinoma is one of the most common malignancies affecting women in developing countries. Molecular studies of breast carcinoma have classified the tumour based on the immunohistochemical staining into 4 subtypes, such as Luminal A, Luminal B, HER2/neu Positive and Triple Negative Breast Carcinoma (TNBC). TNBCs are reported to have an aggressive behaviour and wide metastasis, leading to selective treatment outcomes. AIM: The aim was to study the clinicopathological features such as age, site, tumour size, histopathological type, histologic grade, lymph node status, stage and treatment outcomes of triple negative breast carcinoma...

Introduction: The triple-negative breast cancer (TNBC), defined by the absence of receptors to oestrogen and progesterone and no histochemical expression of human epidermal receptor -2, is associated with a particularly aggressive behavior. The aim of our study was to determine the clinico-pathological, therapeutic and prognostic features associated with this type of breast cancer in Morocco. Methods: A cohort retrospective study, spread over 3 years, was conducted of 116 breast cancer patients, diagnosed between January 2009 and December 2011 at the Regional Center of Oncology...

We report here the case of a young man suffering from a rare germ cell tumour. The patient was a 25-year-old man who was referred to our centre for asthenia, stinging epigastric pain, and an iron deficiency anaemia. Gastroscopy revealed a circumferential vegetating lesion on the second portion of the duodenum. The lesion was indurated at the third portion of the duodenum, responsible for a tight stenosis. A computerized tomography-scan of the chest, abdomen and pelvis, and a pancreatic MRI showed a circumferential lesion with a bi-ductal dilatation (i...

An 80 year-old female presented with ductal breast carcinoma (stage II) three years ago, complained of asthenia and iron-deficiency anemia. No diagnosis was obtained after conventional endoscopy and iron supplements were indicated. Ten months later visible digestive hemorrhage was presented. Upper and lower endoscopy was repeated but non-diagnosis was obtained. Thus, video capsule endoscopy was indicated identifying a stenotic lesion arising in the mucosa of distal jejunum. Histopathological examination revealed a poorly mucinous differentiated signet-ring cell adenocarcinoma with an intense peri-tumoral lymphoid (Crohn´s-like lymphoid reaction) and lympho-vascular infiltration with no nodal metastases (pT3N0;7ª edition TNM classification)...

Papillary breast lesions are a heterogeneous group of tumors which mainly arise in the central mammary region, ranging from benign to malignant. Among them, solid papillary carcinoma (SPC) represents a very uncommon variant with indolent clinical behavior and excellent prognosis. The categorization of papillary lesions as benign, atypical or malignant is often difficult even for experienced pathologists. Furthermore, for prognostic purposes, to decide whether to consider a lesions as in situ when it is not associated with frank invasive foci of carcinoma may be problematic...

INTRODUCTION: Ductal carcinoma in situ (DCIS) is considered a heterogeneous lesion at the molecular level. However, there is a paucity of literature about the existence of molecular subtypes in DCIS which can predict their biological behavior at the preinvasive stage. MATERIALS AND METHODS: Precise prevalence of molecular subtypes of pure DCIS and DCIS component of infiltrating duct carcinoma (IDC) was evaluated using immunohistochemistry and correlated with known prognostic factors...

Lapatinib is an orally bioavailable dual inhibitor of the intracellular domain of both the HER2 protein and the epidermal growth factor receptor. This dual inhibitor can effectively prevent the downstream signal transduction initiated by a tyrosine kinase, thereby reducing the proliferation rate of tumor cells. Lapatinib was demonstrated to be beneficial in patients with HER2-positive locally advanced and metastatic breast cancer. We present here a case of interstitial pneumonitis that occurred after lapatinib treatment...

OBJECTIVE: To study the relationship among Her-2, Ki-67, p53 expression and the clinicopathologic characteristics of breast cancer in the patients of northern China. METHODS: Expression of Her-2, Ki-67, p53 and clinical characteristics of 260 breast cancer patients were retrospectively studied. RESULTS: Her-2 overexpression led to higher incidence rates of infiltrating ductal carcinoma and axillary lymph node metastasis, bigger diameters of the primary tumors, later pTNM staging, and a lower incidence rate of ductal carcinoma in situ (p < 0...

We report on the case of a 67-year-old man with granulocyte colony-stimulating factor (G-CSF) producing anaplastic carcinoma of the pancreas. Preoperative routine tests revealed an elevated white blood cell (WBC) count of 25.2 G/l, consisting almost exclusively of neutrophilic granulocytes (23.31 G/l) with a predominance of segmented neutrophils (78% of all neutrophilic granulocytes), and elevated levels of C-reactive protein at 87 mg/l. Upon surgery, local tumour infiltration was more extensive than expected from preoperative imaging...

Chronic inflammation (CI) is a risk factor for pancreatic cancer (PC) including the most common type, ductal adenocarcinoma (PDAC), but its role and the mechanisms involved are unclear. To investigate the role of CI in PC, we generated genetic mouse models with pancreatic specific CI in the presence or absence of TP53. Mice were engineered to express either cyclooxygenase-2 (COX-2) or IκB kinase-2 (IKK2), and TP53(+/+) or TP53(f/f) specifically in adult pancreatic acinar cells by using a full-length pancreatic elastase promoter-driven Cre...

Interrelations between cytokines, produced by invasive ductal carcinoma (IDC) and fibroadenoma (FA) of the breast, and angiogenic growth factor VEGF-A, expressed in IDC and FA, were investigated. The analysis of the cytokine profiles of IDC and FA was performed by cultivation of tumor biopsy specimens in vitro. Testing of the cytokine-producing reserve of the tumors for production of VEGF-A was conducted by culturing samples of IDC and FA in a medium containing polyclonal activator (a complex of phytohemagglutinin, concanavalin A, and lipopolysaccharide)...

Diagnostic assays for human epidermal growth factor receptor 2 (HER2) expression have a high predictive value because patients with HER2-positive tumors could benefit from HER2-targeted therapy. The aim of the present study is to analyze the incidence of HER2 gene amplification in selected tumors with adverse features that scored 1+ by immunohistochemistry (IHC). For that purpose, 331 consecutive invasive breast cancers (IBCs) were tested by IHC for HER2 expression between January and December 2013, 102 of which (31%) scored 1+...

BACKGROUND: Male breast cancer is a rare event, accounting for approximately 1% of all breast carcinomas. Although men with breast cancer had poorer survival when compared with women, data on prognosis principally derive from retrospective studies and from extrapolation of female breast cancer series. We reported the case of a very long survival patient. CASE PRESENTATION: A caucasian 42-year-old man underwent radical mastectomy with axillary dissection for breast cancer in 1993...
