Breast cancer is one of the top cancer-death causes and specifically accounts for 10.4% of all cancer incidences among women. The prediction of breast cancer recurrence has been a challenging research problem for many researchers. Data mining techniques have recently received considerable attention, especially when used for the construction of prognosis models from survival data. However, exist...
Background: The value of CA15-3(cancer antigen 15-3) marker in early detection of breast cancer recurrence has been studied in several prospective trials. But the results of these studies are different. This may be due to variable cutoff points used for analysis, different intervals between CA15-3 measurements and the differences between patients population. This study was done to examine the p...
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...
patients and methods in this cross-sectional study, data of 584 female patients (mean age of 45.9 years) referred to breast cancer research center (tehran, iran) were analyzed anonymously. spss and norm softwares (2.03) were used for data transformation, running and interpretation of cca and replacing missing values, respectively. data were obtained from breast cancer research center, tehran, i...
Cancer is a collection of diseases that involves growing abnormal cells with the potential to invade or spread to the body. Breast cancer is the second leading cause of cancer death among women. A method for 5-year breast cancer recurrence prediction is presented in this manuscript. Clinicopathologic characteristics of 579 breast cancer patients (recurrence prevalence of 19.3%) were analyzed an...

Background and Objective: IGFs (Insulin-like growth factors) and some binding proteins can cause occurrence and recurrence of breast cancer. Since the role of combined exercise training on these factors is not clear, therefore, the aim of this study was to look at the changes of IGF axis and some binding proteins in postmenopausal women with breast cancer after 15 weeks of combined exercise tra...
Introduction: Breast cancer (BC) is the most common cancer diagnosed in women in Worldwide.A breast cancer diagnosis can be a life-changing and stressful experience that can lead to chronic mental health conditions such as posttraumatic stress disorder (PTSD) and fear of cancer recurrence(FCR). This study examined the effect of written exposure therapy and mindfulness-based stress reduction on...
PURPOSE This study aims to explore gene expression profiles that are associated with locoregional (LR) recurrence in breast cancer after mastectomy. PATIENTS AND METHODS A total of 94 breast cancer patients who underwent mastectomy between 1990 and 2001 and had DNA microarray study on the primary tumor tissues were chosen for this study. Eligible patient should have no evidence of LR recurren...
Background and Objective: Tamoxifen is the most commonly used treatment for the patients with breast cancer called ER +, which prevents the expression of genes that are effective in the growth and proliferation of cancer cells by estrogen. Resistant to Tamoxifen is a major clinical problem in breast cancer treatment. In recent studies, the role of microRNAs in tamoxifen resistance has been rais...
