CONTEXT AND OBJECTIVE Breast cancer is thought to derive from progressively aberrant, non-invasive breast lesions, but it is not known exactly how invasive breast cancer develops from these lesions. The aim of this study was to verify the changes in c-erbB-2 and p53 protein expression between non-neoplastic ducts, ductal carcinoma in situ and invasive ductal carcinoma found in the same breast. ...
We compared the health-related quality of life, impact of the disease, risk perception of recurrence and dying of breast cancer, and understanding of diagnosis of patients with ductal carcinoma in situ (DCIS) and invasive breast cancer 2-3 years after treatment. We included all women (N=211) diagnosed with DCIS or invasive breast cancer TNM stage I (T1, N0, and M0) in three community hospitals ...
PURPOSE The exact definition of pathologic complete response (pCR) and its prognostic impact on survival in intrinsic breast cancer subtypes is uncertain. METHODS Tumor response at surgery and its association with long-term outcome of 6,377 patients with primary breast cancer receiving neoadjuvant anthracycline-taxane-based chemotherapy in seven randomized trials were analyzed. RESULTS Dise...
Numerous studies have observed reduced breast cancer risk with increasing levels of physical activity, yet these findings have been inconsistent about optimal times of activity and effect modification by other factors. We investigated the association between recreational and occupational physical activity and breast cancer risk in a population-based case-control study in Massachusetts, New Hamp...
Background and purpose: Breast carcinoma is the most common malignant tumor leading to death among women. Risk of Metastasis of the tumor, as a major cause of death and disability in these patients is associated with factors such as number of involved lymph nodes, size of tumor, patient age and microscopic degree of the tumor. The aim of this study was to determine the Ë-cadherin manifestatio...
INTRODUCTION Estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER-2) expression are crucial in the biology of breast carcinoma. HER-2/neu gene is amplified and overexpressed in 15-30% of invasive breast cancers. HER-2-positive breast cancers have worse prognosis than HER-2 negative tumors and possess distinctive clinical features. The aim of this ...
background: aberrant methylation of cytosine-guanine dinucleotide islands leads to inactivation of tumor suppressor genes in breast cancer. tumor suppressor genes are unmethylated in normal tissue and often become hypermethylated during tumor formation, leading to gene silencing. we investigated the association between e-cadherin ( cdh1) and estrogen receptor-α (esrα) gene promoter methylation ...
Purpose: Recommended surveillance for BRCA1 and BRCA2 mutation carriers includes regular mammography and clinical breast examination, although the effectiveness of these screening techniques in mutation carriers has not been established. The purpose of the present study was to compare breast magnetic resonance imaging (MRI) with ultrasound, mammography, and physical examination in women at high...
background: there has been increasing trend towards surgical treatment of metastases across different cancer types, including breast cancer, in the recent decade. single metastasis of breast cancer to sternum is a rare situation. we present a case of sternectomy for metastasis from breast cancer. case presentation: a 58-year-old woman with a history of modified radical mastectomy for breast can...
introduction: breast cancer is the second most common cause of brain metastasis. although patient prognosis is poor, isolated brain metastasis occasionally can be an option for treatment with curative intent in breast cancer patients. case presentation: we report a patient with invasive ductal carcinoma of the breast who developed an isolated right frontal lobe metastasis within 5 months of fin...
