## Microsatellite instability (MI + ) is associated with defects in mismatch repair, resulting in a 'mutator' phenotype and the development and progression of cancer. MI + has been documented in invasive breast carcinomas. This study was undertaken to determine whether MI + is found in the early n

โฆ Synopsis
Evidence is mounting that ductal carcinoma in situ (DCIS) is a direct precursor of invasive breast cancer. Recent molecular biological and cytogenetic studies have revealed chromosomal gains and losses involved in breast carcinogenesis. This editorial discusses how the gains and losses on the different chromosomes fit into previously defined morphological routes of progression from normal cells through DCIS to invasive carcinoma, and the possible uses of these gains and losses in the classification of DCIS and the risk assessment of DCIS patients.

Experimental studies suggest that cyclin D1 is a potential oncogene but in clinical studies of invasive breast cancer, overexpression of cyclin D1 is found to be associated with oestrogen receptor (ER) expression and low histological grade, both markers of good prognosis. Immunohistochemistry has be
Cyclin D1 (CCND1) amplification is found in 10-15 per cent of invasive breast carcinomas, but it is not well established whether this gene alteration also occurs in the precursor of invasive breast carcinoma, ductal carcinoma in situ (DCIS). By Southern blot analysis, cyclin D1 gene amplification wa
Background. Ductal carcinoma in situ (DCIS) of the male breast is an uncommon disease, accounting for approximately 7% of all male breast carcinomas. Compared with invasive carcinomas of the breast, the prognosis associated with DCIS in men is excellent; however, clinical features, pathology, and tr
There is strong evidence that ductal carcinoma in situ (DCIS) represents a precursor lesion of invasive breast cancer. In order to analyse specific chromosomal alterations of DCIS, 38 paraffin-embedded specimens of DCIS and six associated invasive carcinomas were examined by means of comparative gen
Ductal carcinoma in situ (DCIS) was a relatively uncommon disease process when we relied on palpation to detect breast lesions. With the advent of more widespread mammography screenings, the surgeon is faced with a welcome opportunity to prevent cancer by dealing with a precursor lesion. Discovering
