the lung cancer is one of the most dangerous cancers and is also the leading cause of cancer death worldwide, accounting for about 1.3 million deaths annually. however in clinical practice, lung cancer therapies commonly do with chemotherapy, although it is hard because the lung cancer may progress to metastasis stage. the metastasis of lung cancer is highly dependent of expression of matrix me...
Although acrometastases are rare but clinically they are considered important. Their etiology is quite different from the metastases to other sites; bronchogenic carcinoma is by far the most frequent case. The prognosis is always similar to metastatic bronchial cancer with an average survival of three mo...
Background and Objective: Oral cancer accounts for less than 3% of all cancers. Despite recent improvement in diagnostic and treatment methods, the overall survival of the disease is unfavorable. Several studies have been performed to assess factors influencing lymph node metastasis and prognosis. The aim of this study was to evaluate some clinical and pathological factors influencing lymph ...
Bone is a common site of metastasis for various types cancer cells, including breast cancer, and the consequent skeleton-related events observed in patients are severe often fatal. Currently, it widely accepted that cancer-associated fibroblasts (CAFs) confer metastasis-promoting property to cells. Furthermore, clinical observations suggest CAFs mediate bone tropism metastatic Therefore, deeper...
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...
Background and purpose: The aim of this study was to estimate the disease-free survival rate, in female patients with breast cancer and determining the level of influencing factors. Materials and methods: In a retrospective cohort study, the records of 377 patients attending Mashhad Omid hospital, Iran, spanning the years 2006 to 2011 were selected using convenience sampling. The patients we...
Background and Objective: Mesenchymal stem cells (MSCs) promote metastasis in colorectal cancer; however, the mechanism underlying this process is not fully understood. Epithelial to mesenchymal transition (EMT) is a key step in tumor acquisition of metastatic phenotype. We aimed to investigate the effect of MSCs on the expression of EMT markers, as well as cancer stem cell markers in HT-29 col...
Cancer is a genetic condition. Some cancers are inherited, but most are caused by mutations in somatic cells. The cause of these mutations is inherent error in the transcription of DNA or exposure to carcinogens. Malignant melanoma is the most serious type of skin cancer which develops from pigment-containing cells known as melanocytes. The most potent risk factors for melanoma is the presence ...
Probiotics are defined as live bacteria and yeasts that exert beneficial effects for health. Among their various effects, anti-cancer properties have been highlighted in recent years. Such effects include suppression of the growth of microbiota implicated in the production of mutagens and carcinogens, alteration in carcinogen metabolism and protection of DNA from oxidative damage as well as reg...
