TL;DR: Maximal bowel displacement with IMRT yields favorable acute GI toxicity and pathologic downstaging profiles, as compared to 3D-CRT in preoperative CRT for rectal cancer and warrants further prospective investigation.

Daily patient setup error in prostate image guided radiation therapy with fiducial-based kilovoltage onboard imaging and conebeam computed tomography.
TL;DR: The residual setup errors following daily kV image guided localization, as determined by CBCT, were small, which demonstrates high accuracy of kV localization when fiducial markers are present.

Cone-beam computed tomography image guided therapy to evaluate lumpectomy cavity variation before and during breast radiotherapy.

TL;DR: Resimulation closer to the time of boost treatment should be considered in patients who are initially simulated within six weeks of surgery and/or with large CTVLC, because the rate of change of the LC is affected by the initial cavity size and the timing from surgery.

Daily Orthogonal Kilovoltage Imaging Using a Gantry-Mounted On-Board Imaging System Results in a Reduction in Radiation Therapy Delivery Errors
Gregory A. Russo,Muhammad M. Qureshi,Minh Tam Truong,Ariel E. Hirsch,Lawrence Orlina,Harry K. Bohrs,P. Clancy,John Willins,Lisa A. Kachnic +8 more
TL;DR: IGRT implementation has a patient safety benefit with a significant reduction in treatment delivery errors and is recommended in routine practice to complement existing quality assurance measures.

Dose-painted intensity-modulated radiation therapy (DP-IMRT) for anal cancer: No differences in treatment toxicity and early outcomes between human immunodeficiency virus (HIV) positive and negative patients.
Paul B. Romesser,Joseph D. Mancias,Muhammad M. Qureshi,Kevan L. Hartshorn,John Willins,Theodore S. Hong,Lisa A. Kachnic +6 more
TL;DR: HIV+ patients on HAART receiving concurrent chemotherapy with DP-IMRT for anal canal cancer showed similar two-year outcomes and no significant differences in acute toxicity compared to HIV- patients, and should be considered eligible for all national trials in which IMRT is employed.
