abstract   background: gastric cancer is the second most common cancer and also the second cancer related death all over the world. in recent years recorded data for tumor has shown a rise in the incidence of gastric cancer in young individuals. the present study was designed to compare some of the epidemiologic characteristics of individuals suffering from gastric cancer aged below and above f...

Lung adenocarcinoma, the most commonly diagnosed type of lung cancer, has a poor prognosis even with combined surgery, chemotherapy, or molecular targeted therapies. Most patients are diagnosed with an in-operable advanced or metastatic disease, both pointing to the necessity of developing effective therapies for lung adenocarcinoma. Surfactant protein B (SP-B) has been found to be overexpresse...

the postgastrectomy recurrence rate is as high as 30-65%, with 5-year overall survival rates of <20%. local recurrence is very common which occurs in 38-45% of cases. the most common sites of locoregional recurrence are the gastric remnant at the anastomosis, the gastric bed, and the regional nodes. the recurrence may occur as early and late events after gastrectomy. most recurrences are early,...

most patients with gastrointestinal cancers refer to the health centers at advanced stages of the disease and conventional treatments are not significantly effective for these patients. therefore, using modern therapeutic approaches with lower toxicity bring higher chance for successful treatment and reduced adverse effects in such patients. the aim of this study is to evaluate the effect of av...

objective(s): in positron emission tomography (pet) studies, thoracic movement under free-breathing conditions is a cause of image degradation. respiratory gating (rg) is commonly used to solve this problem. two different methods, i.e., phase-gating (pg) and amplitude-gating (ag) pet, are available for respiratory gating. it is important to know the strengths and weaknesses of both methods when...

preoperative gleason score (gs) obtained from trans rectal ultra sonography (trus) is the most common grading system to evaluate the appropriate treatment for patients with clinically localized prostate cancer. but this method showed upgraded and downgraded results in comparison to gleason score obtained from radical prostatectomy. the current study aimed to determine clinical or pathological v...

Introduction: Our previous study identified LIM homeobox domain 6 (LHX6) as a frequently epigenetically silenced tumor-suppressor gene in lung cancer. However, its clinical value has never been evaluated, and the in-depth anti-tumor mechanism remains unclear. Methods: Public database was used for lung cancer, lung adenocarcinoma and lung squamous carcinoma patients and tissue microarray data wa...
