Feasibility study of deep inspiration breath-hold based volumetric modulated arc therapy for locally advanced left sided breast cancer patients.
BACKGROUND The purpose of this study was to assess the feasibility of deep inspiration breath-hold (DIBH) based volumetric modulated arc therapy (VMAT) for locally advanced left sided breast cancer patients undergoing radical mastectomy. DIBH immobilizes the tumor bed providing dosimetric benefits over free breathing (FB). MATERIALS AND METHODS Ten left sided post mastectomy patients were imm...

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...

PURPOSE The purpose of this study is to compare the dosimetric differences among volumetric modulated arc therapy (VMAT), fixed-field intensity modulated radiotherapy (IMRT) and three-dimensional conformal radiotherapy (3D-CRT) for the preoperative locally advanced rectal cancer (LARC). METHODS Ten LARC patients treated in our department using the simultaneous escalate strategy were retrospec...

Introduction: The rate of cardiac diseases have increased among patients who underwent radiotherapy for left-sided breast cancer. The study’s aim was evaluate the dose to organs at risk in free-breathing 3-dimensional conformal (FB-3DCRT) against 3-dimensional conformal deep inspiration breath-hold (3DCRT-DIBH) in patients with left-sided breast cancer. Ma...
متن کاملPostmastectomy radiation therapy in locally advanced breast cancer.
Despite wide efforts for early detection of breast cancer using screening mammography, locally advanced breast carcinomas account for a remarkable proportion of all breast carcinomas, particularly in developing countries. Locally advanced breast cancer may have widely different clinical and biological features. Radiotherapy plays an important role in the management of locally advanced breast ca...
