Background & Objective: Ki-67 evaluation is an essential tool to define luminal A and B breast cancers, which is not yet systematized. The International Ki67 in Breast Cancer Working Group suggests the counting of 500 or 1000 cancer cells, which is a time-consuming process. Therefore, novel methods, such as the Eye-10 method and stepwise counting strategy, are proposed to facil...
In this study, we performed high-resolution array comparative genomic hybridization with an array of 4153 bacterial artificial chromosome clones to assess copy number changes in 44 archival breast cancers. The tumors were flow sorted to exclude non-tumor DNA and increase our ability to detect gene copy number changes. In these tumors, losses were more frequent than gains, and gains in 1q and lo...
Introduction & Objective: Genetic agents play important roles in developing of cancers. Mutations and polymorphism affects on p53 protein function in suppressing tumor. We aimed to investigate the intron 3 polymorphism of p53 in Isfahanian breast invasive ductal carcinoma. Materials & Methods: We undertook a case–control study on 192 controls and 192 patients with breast invasive ductal carc...
Background: Breast cancer is the most common malignancy in females worldwide. Several etiological factors including environmental factors have been recognized for breast cancer. Epstein Barr virus as a viral etiological factor has been proposed. So far, several studies have investigated the relationship between development of breast cancer and Epstein Barr virus, but few have been done in Iran....
BACKGROUND Invasive ductal carcinoma is a kind of very typical breast cancer. The goal of our research was to figure out the molecular mechanism of Invasive ductal carcinoma and to find out its potential therapy targets. RESULTS The total amount of 478 differentially expressed genes in Invasive ductal carcinoma which compared with normal breast epithelial cells were recognized. Functional enr...
Skin-sparing mastectomy with immediate breast reconstruction can provide an excellent cosmetic result. Despite its increasing popularity, few studies have assessed the risk of recurrence when the procedure is used for the treatment of ductal carcinoma in situ. To evaluate the oncologic safety of skin-sparing mastectomy used for the treatment of ductal carcinoma in situ, the recurrence rate was ...
Background: Breast pathologies has a greatinfluence on morbidities and mortalities in all nations. Reasons for high prevalence of breast cancer in Iran is a point of intensedebate, which needs more data for better interpretion. Thus, we decided to perform a study showing frequencies of breast pathologies. Methods: In a cross sectional study in Rasule- Akramhospital, we gathered information...
The transition from ductal carcinoma in situ to invasive ductal carcinoma is a key event in breast cancer progression that is still not well understood. To discover the microRNAs regulating this critical transition, we used 80 biopsies from invasive ductal carcinoma, 8 from ductal carcinoma in situ, and 6 from normal breast. We selected them from a recently published deep-sequencing dataset [Fa...
objective: to review her-2/neu and tp53 status and their correlation with all other prognostic clinicopathologic features of infiltrative ductal breast carcinomas. materials and methods: this cross sectional study was performed on 139 patients with infiltrative ductal breast carcinoma who were diagnosed between may 2000 and march 2006 at the surgery and pathology departments of alzahra hospital...
background and objectives: breast cancer is the most common malignancy among women in the world. the aim of this study was to assess estrogen receptor (er), progesterone receptor (pr) and her-2/neu of infiltrating ductal carcinoma (idc) with tumor size, histologic grade, lymph node metastasis and age. methods: this study was carried out on 300 tissue blocks ofpatients with idc who underwent mas...
