cancer starts with a change in one single cell. this change may be initiated by external agents and genetic factors. cancer is a leading cause of death worldwide and accounts for 7.6 million deaths (around 13% of all deaths) in 2008. lung, stomach, liver, colon and breast cancer cause the most cancer deaths each year. in this review, different aspects of gastric cancer; including clinical, path...

Background: Apelin has recently been considered as an adipokine secreted from visceral fat. Apelin and itsreceptor exist in many tissues including lung and play significant roles in many physiological andpathological activities. However, serum level of apelin-12 is unknown in smokers and in various types of lungmalignancies. There...

background: the dosimetric parameters required in lung cancer radiation therapy are taken from a homogeneous water phantom; however, during treatment, the expected results are being affected because of its inhomogeneity. therefore, it becomes necessary to quantify these deviations. objective: the present study has been undertaken to find out inter- and intra- lung density variations and its dos...

Lung cancer is one of the most dangerous diseases that cause a large number of deaths. Early detection and analysis can be very helpful for successful treatment. Image segmentation plays a key role in the early detection and diagnosis of lung cancer. K-means algorithm and classic PSO clustering are the most common methods for segmentation that have poor outputs. In t...

in spite the emergence of potent and broad spectrum antibiotics and recent advances in bronchoscopy and pulmonary physiotherapy, still there is a high rate of morbidity and mortality because of lung abscess. the objective of this study is the indication of risk factors, which have undesirable effects on the prognosis of lung abscess. in a retrospective study, all cases of lung abscess who was c...

inflammatory myopathy is a paraneoplastic syndrome. inflammatory myopathy may be the first manifestation of underlying malignancy. it was reported in patients with colon cancer, breast cancer, ovarian cancer, lung cancer and non-hodgkin lymphoma. there are few reports regarding inflammatory myopathy in patients with gastric cancer. we want to present inflammatory myopathy as early manifestation...

Background: To investigate the expression of TNF-α, IL-6, IL-10 in the plasma of patients with lung cancer who received radiation therapy (RT), and to analyze the correlation between these cytokines and radiation pneumonitis (RP). Materials and Methods: Patients with lung cancer who received 3D-CRT in our hospital were prospectively evaluated. Circulating cytokine levels were measured wit...
