Evaluation of Dose-Volume Histograms after Prostate Seed Implantation

Abstract

A learning curve characterized by an increase in the D90post can be observed and results in a stable technique after 18 patients. An important factor influencing the learning curve in addition to the precision of seed positioning is organ volume definition on postimplant imaging.

Transperineal Permanent Seed Implantation of “Low-Risk” Prostate Cancer

“…Using TPSI, besides the experience of the implanting team an optimal treatment technique in TPSI is essential [13]. Grimm et al [10] implanted 125 patients between 1988 and 1990 and reported a follow-up of 10 years (Figure 3).…”

Changes of Dose Delivery Distribution within the First Month after Permanent Interstitial Brachytherapy for Prostate Cancer

“…Permanent interstitial brachytherapy with 125 I or 103 Pd seed implants is a common treatment for early-stage prostate cancer [7,10,11,16]. Computed tomography-(CT-)based dosimetry is currently recommended as the standard for postimplant dosimetry [1,8,12,13].…”

Comparative Treatment Planning on Localized Prostate Carcinoma

“…Current options for the treatment of organ-confined prostate cancer include radical surgery, photon-based external-beam therapy, brachytherapy or special treatment options such as proton radiotherapy [2,8,12,15,18,20,21,28,30,38].…”
