BACKGROUND/AIM 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 ai...

BACKGROUND The identification of special types of breast cancer might be of value in assessing prognosis and predicting response to therapy. METHODS A total of 7372 consecutive patients with immunohistochemically defined luminal invasive breast cancer operated at the European Institute of Oncology between 1997 and 2005 were included. We then explored patterns of recurrence by histological typ...

PURPOSE Breast cancer is the most common malignancy in American women and the second leading cause of death from cancer. The genetic and epigenetic alterations that initiate and drive cancer can be used as targets for detection of neoplasia in bodily fluids. Tumor cell-specific aberrant promoter hypermethylation can be detected in nipple aspirate and ductal lavage from breast cancer patients. I...

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 Fi...

Recent reports suggest that the finding of lobular neoplasia (atypical lobular hyperplasia [ALH] or lobular carcinoma in situ [LCIS]) in breast core needle biopsy specimens may be associated with an increased risk of both ductal carcinoma in situ (DCIS) or invasive carcinoma at excision. We reviewed our breast core biopsy material to see if we could confirm this finding. From 4,297 biopsies, 71...

Lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) of the breast are cytologically similar breast lesions that reportedly carry different relative risks of subsequent development of invasive carcinoma. They are frequently multifocal and bilateral. We have identified the chromosomal copy number changes in 31 LCIS and 14 ALH lesions from 28 cases and also the 7 invasive carci...

Bilateral risk reducing mastectomy results in the greatest breast cancer risk reduction but is an irreversible intervention. Total mastectomy can never remove all breast tissue and there is always a small risk of breast cancer. Regular follow up and surveillance is beneficial. We present the case of a 47-year-old woman who presented with axillary lymph node metastatic breast cancer after risk r...

Aberrant methylation of promoter CpG islands is a hallmark of human cancers and is an early event in carcinogenesis. We examined whether promoter hypermethylation contributes to the pathogenesis of benign breast lesions along a progression continuum to invasive breast cancer. The exploratory study cohort comprised 17 breast cancer patients with multiple benign and/or in situ lesions concurrentl...

Hyperplastic polyps of the stomach are regarded as benign. However, in rare cases they may contain incipient primary carcinomas. To our knowledge, breast carcinoma metastatic to a gastric hyperplastic polyp has not yet been reported. We describe the case of a 69-year-old woman to whom a gastric polyp was endoscopically excised. The patient had previously undergone a right mastectomy for mixed, ...
