the study of aaag repeat polymorphism in promoter of errg gene and its association with the risk of breast cancer in isfahan region
چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...

Pancreatic tumors show large interfractional position variation. In addition, changes in gastrointestinal gas volumes and body contour take place over the course of radiation therapy. We aimed to quantify the effect of these anatomical changes on target dose coverage, for the clinically used fiducial marker-based patient position verification and, for comparison, also for simulated bony anatomy...
متن کاملDose uncertainties in IMPT for oropharyngeal cancer in the presence of anatomical, range, and setup errors.
PURPOSE Setup, range, and anatomical uncertainties influence the dose delivered with intensity modulated proton therapy (IMPT), but clinical quantification of these errors for oropharyngeal cancer is lacking. We quantified these factors and investigated treatment fidelity, that is, robustness, as influenced by adaptive planning and by applying more beam directions. METHODS AND MATERIALS We us...

Background and Aim: Today, cancer is considered as a major health problem and affects the health of society. Breast cancer is the second leading cause of cancer death in women after lung cancer. According to epidemiological studies, cancer is the second most common cause of death after cardiovascular disease worldwide and the third leading cause of death after cardiovascular disease and acciden...
متن کاملRadiobiological and physical effects of patient setup errors during whole breast irradiation
Background: The dose-related effects of patient setup errors on bio-physical indices were evaluated for the conventional wedge (CW) and field-in-field (FIF) whole breast irradiation techniques (WBI). Materials and Methods: The treatment plans of 10 patients receiving left WBI were retrospectively selected for evaluation. The bio-physical effects of dose variations were evaluated by shifting the...
