The purpose of this work was to determine alternative radiotherapy (RT) regimens that are biologically equivalent to clinically proven treatments using different RT modalities or different fractionation schemes. The concept of equivalent uniform dose

Purpose To evaluate whether real-time intraoperative ultrasound (US)-based dosimetry can replace conventional postoperative computed tomography (CT)-based dosimetry in prostate brachytherapy. Methods and Materials Between December 2001 and November 2

Brachytherapy using permanent seed implants has been an effective treatment for prostate cancer. However, seeds will migrate after implant, thus making the evaluation of post-implant dosimetry difficult. In this study, we developed a computer program

Many factors influence response in low-dose-rate (LDR) brachytherapy of prostate cancer. Among them, edema, relative biological effectiveness (RBE), and dose heterogeneity have not been fully modeled previously. In this work, the generalized linear-q

Parallel in vitro and in vivo studies provide insight into the relationship between clinical response and intrinsic cellular radiosensitivity and may aid in the development of predictive assays. Compilations of radiosensitivity parameters from in vit

No prospective dose escalation study for prostate brachytherapy (PB) with permanent implants has been reported. In this work, we have performed a dosimetric and biological analysis to explore the implications of dose escalation in PB using 125I and 1

Purpose: It has been suggested recently that the α/β ratio for human prostate cancer is low (around 1.5 Gy), and much debate on the evidence for such a low value is ongoing. Analyses reported so far ignored the contribution of tumor repopulation. E

Purpose A sequential two-phase process, initial and boost irradiation, is the common practice for the radiotherapy management of high-risk prostate cancer. In this work, we explore the feasibility of using intensity modulated radiation therapy (IMRT)

Objectives To determine whether the use of biopsy kits with 6 to 12 containers in which biopsies of the prostate are individually submitted and processed reduces the monthly rates of equivocal diagnoses. Methods We searched our computer records for p

Various radiotherapy (RT) modalities, such as external beam radiotherapy(EBRT) and permanent/high-dose-rate (HDR) brachytherapy, have been used for the management of localized prostate cancer. Using the linear-quadratic (LQ) model, we compared the re
