Background: Lung cancer is one of the most common cancers and the leading cause of death due to cancer in the world. It has the highest mortality rate compared to breast, prostate, and other cancers. Different factors can be effective in the survival of lung cancer patients. The present study has evaluated survival and its related factors. Materials and Methods: The present study was performed...

Introduction: Lung cancer is the main cause of mortality in both genders worldwide. This disease is caused by the uncontrollable growth and development of cells in both or one of the lungs. Although the early diagnosis of this cancer is not an easy task, the earlier it is diagnosed, the higher will be the chance of treating. The objective of this study was to develop an optimized prediction mod...

Background: Micro-Ribonocellic Acids (miRNA) are non-coding nucleic acids that are evolutionally protected and have a length of 24-20 nucleotides. MiRNAs control the expression of genes after transcription by mRNA degradation or translation inhibition. By blocking the oncogenic miRNAs and creating the necessary and functional miRNAs (tumor suppressor), these small regulatory RNAs can have thera...

Objective(s): FOXP3 gene is an X-linked gene that encodes FOXP3 protein, an essential transcription factor in CD4+CD25+FOXP3+ regulatory T (Treg) cells.  We aimed, in the present study, to investigate the association of two FOXP3 polymorphisms, -2383 C/T (rs3761549) and IVS9+459 T/C (rs2280883), with lung cancer. Materials and Methods:  In a case-control study we analyzed genotypes and alleles ...

dichloroacetate (dca) as a small, cheap and available anticancer agent, is a pyruvate mimetic compound that stimulates the activity of pyruvate dehydrogenase (pdh) enzyme through inhibition of pyruvate dehydrogenase kinases (pdhk1-4). dca turns on programed cell death (apoptosis) which suppressed in tumor cells and therefore inhibits tumor growth. dca also interferes with the glucose uses of ca...

Background: Hookah smoking has been growing among people because consumers believe that smoking in the form of hookahs has lesser health effects than cigarettes. However, recent reports showed that water pipe smoking (WSP) increased heart rate, blood pressure, impaired pulmonary function and carbon monoxide intoxication. Chronic bronchitis, emphysema and coronary artery disease are serious prob...

Introduction: The proton beam produced in particle accelerators has an appropriate therapeutic potential. In this research, proton therapy of breast cancer is simulated using the MCNPX code in a MIRD phantom, also the contribution of scattered neutron dose during the proton therapy were calculated for the Heart, Lung and Liver.   Materials and Methods: For si...

Background: The potential hazards of exposure to radiation from radon have been of great concern worldwide, as it is associated with an increased risk of lung cancer. Radon (222Rn) and its progeny are the main sources of radioactivity in the environment. The half-life of 222Rn (3.82 days) is long enough for it to diffuse into and build up in homes. 220Rn or thoron from the 232Th series, and 219...

International reviews have concluded that consumption of fruit and vegetables might decrease the risk of lung cancer. However, the relevant epidemiological evidence still remains insufficient in Japan. Therefore, we performed a pooled analysis of data from four population-based cohort studies in Japan with >200 000 participants and >1700 lung cancer cases. We computed study-specific hazard rati...
