P53-binding protein 1 (53BP1) is an early DNA damage response-protein that is rapidly recruited to sites of DNA double-strand breaks. The presence of 53BP1 nuclear foci can be considered as a cytologic marker for endogenous double-strand breaks reflecting genomic instability. This study aimed to clarify the early DNA damage response mediated by 53BP1 in tumor specimens of ductal resection margi...

The development of ectopic breast tissue is attributable to the failure of primitive mammary tissue to regress after the development of the mammary ridge, except at pectoral breast sites, and is most often evident in the axillae. Several benign and malignant breast diseases have been reported in ectopic axillary breast tissues. The most common cancerous pathology of ectopic breast tissue is inv...

AIM To study the protein expression patterns of MUC5AC and MUC6 in normal and diseased breast tissues and to compare their expression with that of a mucin (MUC1) normally expressed in mammary tissues. METHODS Formalin fixed, paraffin wax embedded tissue from 69 cases of invasive breast carcinoma and surrounding breast tissue was studied immunohistochemically with monoclonal antibodies against...

INTRODUCTION Rapidly enlarging mammary tumors, including invasive breast tumors, are clinically rare. Invasive micropapillary carcinoma (IMPC) of the breast is known to have aggressive behavior and poor clinical course compared to invasive ductal carcinoma. CASE PRESENTATION An 87-year-old woman presented with a rapidly enlarging tumor of the right breast over the course of 3 weeks. Ultrasono...

BACKGROUND Although the prognosis in malignant resectable intraductal papillary mucinous tumours of the pancreas (IPMT) is often considered more favourable than for ordinary pancreatic ductal adenocarcinoma, the long term outcome remains ill defined. AIMS To assess prognostic factors in patients with malignant IPMT after surgical resection, and to compare long term survival rates with those o...

Genomic instability is a hallmark of breast and other solid cancers. Presumably caused by critical telomere reduction, GI is responsible for providing the genetic diversity required in the multi-step progression of the disease. We have used multicolor fluorescence in situ hybridization and 3D image analysis to quantify genomic instability cell-by-cell in thick, intact tissue sections of normal ...

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 opera...

Infiltrating ductal carcinoma is the most common form of invasive breast cancer. It accounts for 80% of all types of breast cancer. We report an unusual presentation of histologically proven case of infiltrating ductal carcinoma of breast presented clinically as a small palpable areolar dermal lesion. Well defined hypoechoic cystic lesion in areolar dermis was present on ultrasound with a negat...

  Abstract   Background: The polymorphic variants at codon 72 of the p53 gene, encoding either   proline or arginine at residue 72, produce marked change in the structure of p53.   From the evidence that the DNAmismatch repair system and p53 interact to maintain   genomic integrity, we hypothesized that the codon 72 variation may influence the   prevalence of microsatellite instability a featur...
