abstract background: lung cancer is an important cause of cancer mortality. mortality is a familiar projection to address the burden of cancers. however, according to iranian death registry, about 20% of death statistics were still recorded in misclassified categories. the aim of this study was to estimate lung cancer mortality in iranian population, using bayesian approach to revise this miscl...

Background and purpose: Breast cancer is the most common type of cancer among women. In radiation therapy for breast cancer it is important to prevent damage to normal tissues particularly to lung tissue. In this study, we investigated the incidence of damage in patients with breast cancer by clinical and dosimetric parameters to identify the predictive factors. Materials and methods: An exp...

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...

We present a case of cervical cancer treated by concurrent chemoradiation. In radiation therapy part, the combination of the whole pelvic helical tomotherapy plus image-guided brachytherapy with megavoltage computed tomography of helical tomotherapy was performed. We propose this therapeutic approach could be considered in a curative setting in some problematic situation as our institution.

Gafchromic XRCT, radiochromic film is assessed over a broad energy range, from kilovoltage to megavoltage x rays for variations in reflected optical density to dose response. A large energy dependence was found with reflected optical density output for the same delivered dose varying from 7.8±0.35 at 25.5keV (50kVp) peaking at 12.1±0.5 at 54keV (125kVp) to 0.975±0.03 at 2300keV (10MV) when norm...

Lung cancer is a very aggressive and most deadly cancer in both men and women. Lung cancer is divided into two types of small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC). NSCLC is divided into 3 subgroups: adenocarcinoma (AC), squamous cell carcinoma (SqCC) and large cell carcinoma (LCC). Dopamine is involved in controlling motions, cognition, emotions, memory and reward mech...
