BACKGROUND EBT and EBT3 radioChromic films have been used in radiotherapy dosimetry for years. OBJECTIVE The aim of the current study is to compare EBT and EBT3 radioChromic films in dosimetry of radiotherapy fields for treatment of parotid cancer. METHODS Calibrations of EBT and EBT3 films were performed with identical setups using a 6 MV photon beam(More)
The detection of KRAS and BRAF mutations is a crucial step for the correct therapeutic approach and predicting the epidermal growth factor receptor (EGFR)-targeted therapy resistance of colorectal carcinomas. The concomitant KRAS and BRAF mutations occur rarely in the colorectal cancers (CRCs) with the prevalence of less than 0.001% of the cases. In(More)
Inflammation plays a key role in the development of colorectal cancer. Several studies revealed that inflammatory disease of the colon, such as Crohn’s disease and Ulcerative colitis, substantially increase the risk of colorectal cancer (Lennard-Jones et al., 1977; Lashner et al., 1989; Rhodes and Campbell, 2002). Prostaglandins are molecules of particular(More)
BACKGROUND The prostaglandin-endoperoxide synthase 2 [PTGS2, commonly known as cyclooxygenase-2 (COX-2)] is an enzyme induced by proinflammatory stimuli that is often overexpressed in malignant tissue and involved in the synthesis of prostaglandins and thromboxanes, regulators of processes such as inflammation, cell proliferation, and angiogenesis, all(More)
OBJECTIVE Radiochromic EBT3 film is a later generation of radiochromic films. The aim of this study is to compare EBT and EBT3 radiochromic films in radiotherapy fields of breast cancer. METHODS A RANDO phantom was irradiated by a 6 MV Siemens Primus linac with medial and lateral fields of radiotherapy of breast cancer. Dosimetry was performed in various(More)
