Interfraction variation in prostate cancer - analysis of 11726 cone-beam CT
Popis výsledku v původním jazyce
Purpose: To investigate the setup margins in prostate cancer treatment without using daily online repositioning methods. Methods: We analysed the data from patients treated with curative-intend radiotherapy. Each patient underwent a series of pretreatment online localizations during daily setup using cone-beam CT. The skin-prostate shifts and bone-prostate shifts were recorded in anteroposterior (AP), craniocaudal (CC), and laterolateral (LL) direction. The safety margins based on van Herk equation (2.5Sigma+0.7 sigma) were calculated and the correlations between margins and various patient characteristics and prostate locations were investigated. Results: A total of 307 patients were included, representing 11,726 localizations resulting in 70,356 shifts. The mean skin-prostate setup inaccuracy was 0.8 +/- 5.4mm in AP, 1.3 +/- 4.8mm for CC, and 0.1 +/- 5.6mm in LL direction. The mean bone-prostate setup inaccuracy was 0.4 +/- 3.3mm in AP, 0.1 +/- 2.5mm for CC, and 0.1 +/- 1.4mm in LL
