background: breast cancer arising in young patients (≤ 40 years) is being considered as a distinct clinical entity with more aggressive tumor features and poorer survival. our aim was to assess the impact of age on survival among a large group of iranian women diagnosed with breast cancer. methods: in a cross-sectional study, demographic and clinicopathological characteristics of patients with ...
introduction: acute myeloid leukemia (aml) is a clonal disease characterized by heterogeneous involvement of hematopoietic bone marrow cell populations. in aml patients, a variety of clinical and biologic parameters, including surface markers, have been examinedfor potential value in predicting treatment response and survival. by checking the myeloid, lymphoid and nonspecific markers on the bla...
background and purpose: the goal of this study is application of the proportional hazards model (ph) and accelerated failure time model (aft), with consideration weibull distribution, to determine the level of effectiveness of the factors affecting on the level of disease-free survival (dfs) of the patients with breast cancer. materials and methods: based on the retrospective descriptive studie...
Background: Due to limited clinical data in pediatric-type sarcomas (rhabdomyosarcoma, Ewing's sarcoma, PNET, and desmoplastic small round-cell tumor), the aim of this study was to evaluate the demographic characteristics and identifying prognostic factors for survival. Materials and Methods: We retrospectively reviewed 110 patients with pediatric-type sarcomas. Overall and disease free surviva...
Background:The incidence rate of head and neck cancer in the world is about 560,000 new cases a year. Larynx cancer is the most common malignancy in head and neck in Iran. The most common head and neck carcinoma is the malignancy of squamous epithelial cells. This study was conducted to determine the survival rate of patients undergoing nonsurgical treatment methods for larynge...
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...
background: triple negative breast cancer (tnbc) is reported to be associated with a high risk of recurrence, poor overall survival (os), and disease-free survival (dfs) rates. this study evaluated the clincopathological features and survival of non-metastatic tnbc women in the capital of iran compared with other areas of the world. methods: in a retrospective study, 119 women with tnbc based o...
Background: Mediterean region. Disease-free survival is common to evaluate the treatment of cancers. Severalfactors have been determined as prognostic factors for disease-free survival in studies.Breast cancer is the most common cancer among women especially in easternMethods: in Fayazbakhsh hospital, Tehran.

Background & Objectives: Colon cancer is currently of high incidence and mortality rate. Identifying the factors influencing its prognosis can be very beneficial to its clinical treatment. Recent studies have shown that lymph nodes ratio can be considered as an important prognostic factor. The aim of the present study is to investigate the effect of this factor on the prognosis of the ...
Background and Aim: Many researchers have studied survival (time to death) of gastric cancer patients. Although gastric cancer diagnosed in early stages can be cured by surgery, chance of relapse still exists after operation. Hence, we should consider both events, that is, relapse of the disease and death, in order to be able to make a more precise estimation for survival of the patients. The p...
