background and objective: the dbc2 (deleted in breast cancer 2) or rhobtb2 (located on 8p21) is a tumor suppressor gene associated with tumorigenesis. mutational studies of dbc2 at its promoter region in breast cancer revealed an important role for epigenetic changes contributing to its low expression. epigenetic changes through hypermethylation of the promoter can cause the inactivation of dbc...
Breast cancer, as a heterogeneous disease, includes a wide range of pathological and clinical behaviors. Current treatment protocols, including radiotherapy, chemotherapy, and hormone replacement therapy, are mainly associated with poor response and high rate of recurrence. Therefore, more efforts are needed to develop alternative therapies for this type of cancer. Immunotherapy, as a novel str...

background: chemotherapy-induced amenorrhea is one of long term side effects of adjuvant chemotherapy in patients with breast cancer which may interfere with their future reproductive function. although amenorrhea is well recognized, the actual incidence following taxanes remains uncertain. methods: in a cross sectional study, we identified breast cancer patients aged 45 years or younger who we...
Abstract Introduction: Estrogen receptor-positive (ER-positive) breast cancer is a subgroup of breast tumors that is more likely to respond to hormone therapy. ER-positive and ER- negative breast cancers tend to show different patterns of metastasis because of different signaling cascade and genes that are activated by estrogen response. Genetic factors can contribute to high rates of metastas...

Background: The breast cancer is the most common type of cancer in Iran. Hence determination of the optimal treatment and the contributing factors are important. The main aim in current study was to determine the association between tumor infiltration of lymphocytes (TIL) and complete pathological response in breast cancer patients after neoadjuvant chemotherapy. Methods and materials: In this...
Introduction: Breast cancer is one of the most common types of cancer and the most common type of malignancy in women, which has been growing in recent years. Patients with this disease have a chance of recurrence. Many factors reduce or increase this probability. Data mining is one of the methods used to detect or anticipate cancers, and one of its most common uses is to predict the recurrence...
Background: Breast cancer is the malignancy in humans and other mammals. Several risk factors are involved in their appearance such as higher hormone levels and obesity. Identification of a mouse mammary tumor virus supports a viral etiology for breast tumors in animals. Viruses have been implicated in the development of various cancers, but viral induction for formation breast cancer is contro...
Background and objectives: Breast carcinoma is one of the most common malignant diseases among women worldwide. In Iraq there are noticeable elevation in incidence rates and prevalence of advanced stages of breast cancer. Cobalamin (vitamin B12) is essential micronutrient involved in one carbon metabolism and DNA methylation, which affects cancer. All of these may be change in breast cancer. Th...
