PURPOSE To assess the effect of tumor detection method (screening versus symptom-based diagnosis) in predicting breast cancer survival and investigate how biological features of breast cancer are related to the tumor detection method. PATIENTS AND METHODS The study population consisted of 5,481 women diagnosed with primary invasive breast cancer between 1997 and 2005 and received their treatm...
A major problem of current cancer research and therapy is prediction of tumor recurrence after initial treatment, rather than the simple biological characterization of the malignancy and proliferative properties of tumors. Breast conservation therapy (BCT) is a well-approved, standard treatment for patients with early stages of breast cancer, which consists of lumpectomy and whole-breast irradi...
Background and Aim: Breast cancer is an increasingly important social problem throughout the world. Rate of disease-free survival can be used to evaluate the effects of treatment and disease outcome and assess indices of disease prevention, diagnosis and treatment. With this aim in mind we made an assessment of 5-year disease-free survival in breast cancer patients. Material and Methods: 403 br...
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: we conducted a retrospective analysis to evaluate the impact of omission of supraclavicular radiotherapy on supraclavicular failure rate and treatment outcomes in n1 breast cancer patients with evaluation of prognostic factors that affected supraclavicular recurrence free survival. methods: this study analyzed the medical records of 109 patients with n1 breast cancer. all patients u...
Introduction: Psycho-spiritual therapy (mind-body spirituality) is a multidimensional, transpersonal, and integrative intervention for breast cancer survivors. This study aimed to determine the effectiveness of counseling based on transpersonal psychotherapy (spirituality therapy, mind and body) in reducing the fear of recurrence in breast cancer survivors. Methods: This was a randomized contro...
The prediction of breast cancer recurrence is a crucial problem in research that requires accurate and efficient models. This study aims to compare the performance different machine learning techniques predicting types recurrence. In this study, logistic regression, decision tree, K-Nearest Neighbors, artificial neural network algorithms was compared on dataset. results show algorithm outperfor...
Background: Breast cancer is one of the most common recurrence cancers among women. There are several factors that can affect the multiple recurrence of this disease, which have been studied and recognized in various studies, however, with the fact that these factors are known, can not always accurately predict the incidence of metastasis. On the other hand, simultaneous examination of the type...
mri of the breast has evolved as a non-invasive imaging modality and is ideally suited for several indications e.g. pre-operative staging and screening in women at increased risk for breast cancer. the widespread use opens also the discussion on over-diagnosis if only 20 - 30 out of 100 mri - guided breast biopsies lead to the diagnosis of breast cancer. thus mri based strategies are needed to ...
Introduction: Breast cancer is the most common cancer in women. Patients are treated with chemotherapy initially, and if not chemically treated, the risk of recurrence of the disease increases yearly. Therefore, methods for identifying patients for whom chemotherapy would be most beneficial are very important. The Oncotype DX test is a prognostic assay that predicts the likelihood of breast can...
