background & objectives: anaplastic lymphoma kinase (alk) is a receptor tyrosine kinase involved in the genesis of several human cancers. alk was initially identified because of its involvement in anaplastic large cell lymphoma (alcl). alk is believed to foster tumorigenesis following activation by autocrine and/or paracrine growth loops. studies reveal that the presence of anti-alk antibod...

Objectives This study aimed to assess PD-1gene polymorphism in salivary gland tumors in patients referred to Khalili Hospital in Shiraz. Methods This case-control study evaluated 48 patients with salivary gland tumors and 100 age- and sex-matched healthy controls. First, 5cc blood samples were obtained from patients and transferred to vials containing anti-coagulated EDTA. DNA was extracted, a...

objective: garlic (allium sativum) has anti-inflammatory, anti-mutagenesis, and immunomodulatory properties that modulate anti-tumor immunity and inhibit tumor growth. in this study we have examined the effect of a protein fraction isolated from fresh garlic on anti-tumor response and intra-tumor lymphocyte infiltration. materials and methods: in this experimental study a protein fraction was p...

background: bax and bcl-2 are the major members of bcl-2 family whose play a key role in tumor progression or inhibition of intrinsic apoptotic pathway triggered by mitochondrial dysfunction. therefore, the balance between pro- and anti-apoptotic members of this family can determine the cellular fate. methods: in this study, the relative level of mrna expression of bax and bcl-2 genes was deter...

introduction: the presence of her-2 has been shown to be a prognostic factor in many kinds of cancers, but its role in head and neck squamous cell carcinoma (hnscc) is not still defined. the purpose of the current study is to investigate the role of her-2 in hnscc and its correlation with various clinicopathologic parameters.   materials and methods: peripheral blood samples were obtained from ...

PURPOSE To investigate the correlated factors for lymph node metastasis and prognosis for patients with T2 gastric cancer. METHODS A total of 442 patients with T2 gastric cancer who underwent gastrectomy from January 1996 to December 2009 were evaluated. The clinicopathological parameters were analyzed for lymph node metastasis and prognosis, including gender, age, tumor size, tumor location,...

Introduction: Stereotactic Gamma Knife radiosurgery has been widely used for treating brain tumors. The scattered radiation outside of treatment field (peripheral dose) can induce the secondary cancer to specific organ. This paper investigated the absorbed dose to eyes, thyroid, heart, lung, breast and colon using a Monte Carlo technique for Mird phantom. We also study the ef...

background and objectives: rcc is one of the most common genitourinary cancers. accurate prediction of prognosis would be valuable for adjuvant trial design, counseling and effectively scheduling follow up visits. p53 is a tumor suppressor gene that expresses a protein that involved in both cell-cycle arrests after dna damage and apoptosis. presence of mutated p53 protein in tumors has been rel...

papillary microcarcinoma of thyroid (pmc) as a variant of papillary carcinoma less than 1 cm in size is a new clinicopathological entity, with high incidence and good prognosis. there are many differences between pmc and clinically apparent papillary thyroid carcinoma. also, there are some pmc case reports with unusual metastasis and aggressive courses. prognostic factors are age, size and morp...
