Radiobiological optimization comparison between pulse-dose-rate and high-dose-rate brachytherapy in patients with locally advanced cervical cancer.

Only scarce data are available on the possibility to include radiobiological optimization as part of the dosimetric process in cervical cancer treated with brachytherapy (BT). We compared dosimetric outcomes of pulse-dose-rate (PDR) and high-dose-rate (HDR)-BT, according to linear-quadratic model.

Dosimetric comparison of circular Eye Physics and Collaborative Ocular Melanoma Study plaques to treat uveal melanoma.

We sought to formally compare Collaborative Ocular Melanoma Study (COMS) and similar-shaped (circular) eye physics (EP) plaques dosimetrically by examining both tumor coverage and critical structure doses.

Long-term oncological and functional outcomes support use of low-dose-rate brachytherapy with or without external beam radiation in young men (≤60 years) with localized prostate cancer.

To evaluate the oncological and functional outcomes of young men treated with low-dose-rate brachytherapy (BT) for prostate cancer (PCa).

Comparison of the prognostic value of F-18 FDG PET/CT metabolic parameters of primary tumors and MRI findings in patients with locally advanced cervical cancer treated with concurrent chemoradiotherapy.

To evaluate the effect of metabolic parameters of pretreatment primary tumor and regional lymph nodes with F-18-FDG PET/CT compared with MRI findings for the prognostic value and disease-free survival (DFS) in locally advanced cervical cancer.

Individualized 3D-printed templates for high-dose-rate interstitial multicathether brachytherapy in patients with breast cancer.

High-dose-rate, multicatheter interstitial brachytherapy is technically complex and operator-dependent, requiring lengthy training and specialized skills. Furthermore, until the advent of contouring on computerized tomography (CT) images, difficulties existed in locating the target volume precisely. The present article reports the results of a study that aimed at producing and validating a 3D-printed template to aid in target volume localization for multicatheter interstitial brachytherapy in patients with ...

Prostate-specific antigen bounce in patients treated before 60 years old by iodine 125 brachytherapy for prostate cancer is frequent and not a prognostic factor.

The only prognostic factor of prostate-specific antigen (PSA) bounce in prostate cancer found in several studies is young age but has never been specifically studied in this subset of patients for long-term results. Bounce characteristics, histological, clinical, and dosimetric data in young patients were analyzed, as well as their impact on toxicity and survival.

Predictive factors of long-term rectal toxicity following permanent iodine-125 prostate brachytherapy with or without supplemental external beam radiation therapy in 2216 patients.

We analyzed factors associated with rectal toxicity after iodine-125 prostate brachytherapy (BT) with or without external beam radiation therapy (EBRT).

Evaluation of the "Quadrella" at 3 years: New index to assess functional and oncological performance specific to prostate brachytherapy.

"Quadrella" index has been recently developed to assess oncological and functional outcomes after prostate brachytherapy (PB). We aimed to evaluate this index at 1, 2, and 3 years, using validated questionnaires, assessed prospectively.

Five fraction accelerated partial breast irradiation using noninvasive image-guided breast brachytherapy: Feasibility and acute toxicity.

To improve efficiency, convenience, and cost, a prospective phase II trial was initiated to evaluate accelerated partial breast irradiation delivered with noninvasive image-guided breast brachytherapy (NIBB) via five once-daily fractions.

The role of radiation therapy in the treatment of Stage II endometrial cancer: A large database study.

The optimum adjuvant treatment for Stage II endometrial cancer patients is unknown. External beam radiation therapy (EBRT) is often considered the standard of care; however, retrospective series suggest that brachytherapy (BT) alone may be sufficient for selected patients. As randomized data are lacking, we used a large database to explore this question.

New approach of ultra-focal brachytherapy for low- and intermediate-risk prostate cancer with custom-linked I-125 seeds: A feasibility study of optimal dose coverage.

To present the feasibility study of optimal dose coverage in ultra-focal brachytherapy (UFB) with multiparametric MRI for low- and intermediate-risk prostate cancer.

Assessment of a source position checking tool for the quality assurance of transfer tubes used in HDR 192Ir brachytherapy treatments.

The determination of source positions before treatment is an essential part of the quality assurance (QA) associated with high dose rate brachytherapy treatments. The purpose of this study was to design and commission a tool to allow the quantification of source positions across multiple transfer tube types.

Comments on "Low-dose-rate prostate brachytherapy: 4-8 week postimplant prostate-specific antigen a novel predictor of biochemical failure-free survival".

Deformable image registration-based contour propagation yields clinically acceptable plans for MRI-based cervical cancer brachytherapy planning.

To study the dosimetric impact of deformable image registration-based contour propagation on MRI-based cervical cancer brachytherapy planning.

A Medicare cost analysis of MRI- versus CT-based high-dose-rate brachytherapy of the cervix: Can MRI-based planning be less costly?

While some institutions deliver multiple fractions per implant for MRI-based planning, it is common for only one fraction to be delivered per implant with CT-based cervical brachytherapy. The purpose of this study was to compare physician costs, hospital costs, and overall costs for cervical cancer patients treated with either CT-based or MRI-based high-dose-rate (HDR) cervical brachytherapy to determine if MRI-based brachytherapy as described can be financially feasible.

Validation of MRI to TRUS registration for high-dose-rate prostate brachytherapy.

The objective of this study was to develop and validate an open-source module for MRI to transrectal ultrasound (TRUS) registration to support tumor-targeted prostate brachytherapy.

A comparison of early prostate-specific antigen decline between prostate brachytherapy and different fractionation of external beam radiation-Impact on biochemical failure.

The aim of this study was to compare early prostate-specific antigen (PSA) decline patterns and PSA nadirs between low-dose-rate seed prostate brachytherapy (LDR-PB) and different fractionations of external beam radiotherapy (EBRT) and their predictive importance for biochemical failure (bF).

Cost-effectiveness of adjuvant intravaginal brachytherapy in high-intermediate risk endometrial carcinoma.

We assessed the cost-effectiveness of adjuvant intravaginal brachytherapy (IVBT) vs. observation after total hysterectomy and bilateral salpingo-oophorectomy (TH/BSO) for high-intermediate risk (HIR) endometrial carcinoma.

Efficacy and safety of iodine-125 radioactive seeds brachytherapy for advanced non-small cell lung cancer-A meta-analysis.

This meta-analysis was conducted to investigate the efficacy and safety of 125I brachytherapy for locally advanced non-small cell lung cancer (NSCLC).

Treatment planning considerations for permanent breast seed implant.

To determine an optimal planning strategy for permanent breast seed implant that minimizes dose heterogeneity without degrading coverage and conformity.

Limitations in learning: How treatment verifications fail and what to do about it?

The purposes of this study were: to provide dialog on why classic incident learning systems have been insufficient for patient safety improvements, discuss failures in treatment verification, and to provide context to the reasons and lessons that can be learned from these failures.

Clinical outcomes using image-guided interstitial brachytherapy for definitive cervical cancer patients with high-risk clinical target volumes greater than 30 cc.

Given the limited data using an interstitial approach with 3D-based planning for definitive cervical cancer utilizing the GEC-ESTRO defined high-risk clinical target volume (HR-CTV), we reviewed our institutional experience of cervical cancer patients with HR-CTVs ≥ 30 cc to determine whether our clinical and toxicity outcomes are acceptable.
