To evaluate the association between pelvic bone marrow (BM) dose volume parameters and probability of acute hematological toxicity (HT), a cohort cervical cancer patients receiving definitive chemoradiation (CRT) was assessed.Medical records treated by CRT (45 Gy in 25 fractions, without constraints applied to BM) were reviewed. Baseline weekly collected. BM retrospectively delineated divided into sub-sites: iliac crests, lower pelvis, lumbosacral region. volumes (V) 5, 10, 20, 30, 40 (V5,...

Residual distal parametrial involvement after radiochemotherapy is a true challenge for brachytherapists since the width and asymmetry of high-risk clinical target volume (HR-CTV) are difficult to cover properly with standard implant.Dosimetric plans five patients treated Venezia advanced gynecological applicator at our institution were reviewed. For each patient, we compared original plan new where oblique needles removed re-optimized manually. Optimization process was halted when EQD210...

The dose calculation algorithms, integrated in a radiotherapy treatment planning system, use different approximations to swiftly compute the distributions. Any biological effect is somehow related delivered tissues. Thus, optimization of radiation oncology requires, as basis, most accurate carry out best possible prediction Normal Tissue Complication Probability (NTCP), well Tumor Control (TCP). Presently, number bio-mathematical models exist estimate TCP and NTCP from physical calculated...

Purpose: Prostate cancer patients with bilateral prosthetic titanium hips present a unique challenge for external beam radiotherapy. Titanium prostheses cause kVCT streak artifacts resulting in inaccurate CT numbers. Megavoltage x-ray attenuation through can be as high 64%. Task group report #63 of the AAPM recommends avoidance accurate dose calculations. In this study, we will compare Tomotherapy, IMRT and Rapid Arc treatment plans using MVCT data sets, passing avoiding prostheses. Method...

Background: The three-dimensional image-guided radiation therapy is very important in volumetric modulated arc (VMAT) to enhance accuracy throughout the course of a patient's treatment. image guidance can ensure safe administration prescribed dose patient. Aim: This study investigated patient set-up uncertainties based on three different registration methods cone bean CT (CBCT) using for clinical sites. Methods: A total 396 CBCT performed lung VMAT plan verification as per institution...
