MUlticentre REtrospective comparison of definitive EBRT with or without HDR BRAchytherapy boost in patients with locally-advanced prostate cancer and regional lymph NOde metastases (MUREBRANO) - A propensity score matched analysis.

Background: Patients treated for clinically node-positive prostate cancer (PCa) are at high risk of recurrence. Local radiation dose escalation with brachytherapy (BT) has been shown to improve outcomes in advanced localised disease, but evidence is lacking for patients with pelvic lymph node metastases.

Methods: We retrospectively collected data on patients treated for clinically node-positive PCa with definitive external beam radiation therapy (EBRT) and androgen-deprivation therapy (ADT), with or without dose-escalation to the prostate using high-dose-rate (HDR)-BT.

Orchiepididymitis as a rare complication of TURP performed four weeks after high-dose-rate brachytherapy for prostate cancer.

The aim of this paper was to present a rare complication of orchiepididymitis in a patient treated with brachytherapy (BT) for prostate cancer, who underwent trans-ureteral resection of the prostate (TURP) four weeks after BT. A 73-year-old patient with prostate cancer (intermediate-risk group) was eligible for high-dose-rate (HDR) BT combined with androgen deprivation therapy (ADT) for 6 months (leuprorelin). Due to increased symptoms, such as urinary retention after BT, the patient required catheterization.

Salvage brachytherapy for recurrent prostate cancer after radiotherapy: An expert-endorsed review by uroGEC.

Radiorecurrent prostate cancer remains a challenging clinical scenario. Salvage brachytherapy, either low-dose-rate (LDR) or high-dose-rate (HDR), offers a promising organ-preserving option in carefully selected patients. This narrative review, endorsed by the uroGEC (Urology - Groupe Européen de Curiethérapie), summarizes current evidence, indications, techniques, outcomes, and limitations of SBT in men with local recurrence after primary radiotherapy.

COMIRI - COMplexity Index of interventional Radiotherapy (brachytherapy) Implants: assessment of procedures based on type, equipment, and team.

Historically, several classification systems have been used for brachytherapy, and they were based on the type of clinical purpose, type of implant and timing of the implant, dose-rate, and type of loading for treatment delivery. However, over the last decades, there have been some major technological advancements, including the introduction of image-guidance and possibility to modulate the dose delivered, which have led several authors (in order to highlight the differences between old technique and new approach) to label it in a different way by replacing "brachytherapy" with "interventional radiotherapy". Modern interventional procedures involve several key aspects, which contribute to the complexity of implant phase, such as implant type, imaging used during the procedure, and role of multi-disciplinary team in operating room.

Comparison of image registration methods in patients with non-melanoma skin cancer treated with superficial brachytherapy.

The accumulated dose from sequential treatments of metachronous non-melanoma skin cancer can be assessed using image registration, although guidelines for selecting the appropriate algorithm are lacking. This study shows the impact of rigid (RIR), deformable (DIR) and deformable structure-based (SDIR) algorithms on the skin dose. DIR increased: the maximum dose (39.

Biochemical control in intermediate- and high-risk prostate cancer after EBRT with and without brachytherapy boost.

Purpose: External beam radiotherapy (EBRT) with or without brachytherapy boost (BTB) has not been compared in prospective studies using guideline-recommended radiation dose and recommended androgen-deprivation therapy (ADT). In this multicenter retrospective analysis, we compared modern-day EBRT with BTB in terms of biochemical control (BC) for intermediate-risk (IR) and high-risk (HR) prostate cancer.

Methods: Patients were treated for primary IR or HR prostate cancer during 1999-2019 at three high-volume centers.

Physical parameters in thermal imaging of basal cell cancer patients treated with high-dose-rate brachytherapy - first study.

Background: The basal cell carcinoma (BCC) is often treated by surgery or radiotherapy using ionizing radiation. While there is an established diagnostic path before treatment and also for the follow-up there are no good noninvasive methods objectifying irradiated area evolution during treatment. The main goal of preliminary studies was to try to answer if there are any useful information that can be derived from temperature effects of high-dose-rate (HDR) brachytherapy in treatment of BCC.

Pre-Treatment Hemoglobin Concentration and Absolute Monocyte Count as Independent Prognostic Factors for Survival in Localized or Locally Advanced Prostate Cancer Patients Undergoing Radiotherapy.

The prognostic value of inflammatory indices, such as the absolute monocyte count (AMC), has been a subject of interest in recent prostate cancer (PCa) studies, while hemoglobin concentration (HGB) has been recognized as a survival factor in castration-resistant metastatic prostate cancer, but its value remains unclear in localized diseases. The aim of this study was to test the prognostic value of these two simple and inexpensive biomarkers for survival and was based on a cohort of 1016 patients treated with primary radiotherapy and androgen deprivation therapy for localized or locally advanced intermediate- or high-risk PCa. Complete survival data were available for all cases and were based on the National Cancer Registry, with a median observation time of 120 months (Interquartile Range (IQR) 80.

Magnetic resonance imaging in cervical cancer interventional radiotherapy (brachytherapy): a pictorial essay focused on radiologist management.

The standard treatment for locally advanced cervical cancer (LACC) is platinum-based chemotherapy in association with external beam radiotherapy (EBRT) and brachytherapy (BT), often also called 'interventional radiotherapy' (IRT). Magnetic resonance imaging (MRI) is the most accurate imaging modality for both staging and response evaluation; therefore MRI-guided IRT has become the method of choice for planning a radiation boost after EBRT. The aim of this paper was to describe the MRI radiological workflow currently ongoing at our Institution.

In-bore MR prostate biopsy - initial experience.

Introduction: The introduction of multiparametric MRI (mpMRI) has been a breakthrough in the diagnosis of noninvasive clinically significant prostate cancer. Currently, MR-guided prostate biopsy (in-bore biopsy) is the only biopsy method that uses real-time MRI in patients with suspected prostate cancer. The aim of the study was a retrospective analysis of the correlation between MRI results and histological findings of prostate samples suspected of malignancy, which were taken during MRI-guided biopsy.

High dose rate brachytherapy in nonmelanoma skin cancer-Systematic review.

Nonmelanoma skin cancers (NMSCs) are the most common malignancies worldwide. Millions of new cases every year present challenge to healthcare systems. Recent years brought numerous new data concerning high dose rate (HDR) brachytherapy (BT) as treatment option for NMSCs.

Pre-operative high-dose-rate brachytherapy in early-stage cervical cancer: long-term single-center results.

Purpose: The aim of the study was to report the outcomes of pre-operative high-dose-rate brachytherapy (pHDR-BT), followed by hysterectomy in patients with early cervical cancer.

Material And Methods: From January, 1998 to December, 2003, 113 women with IB1, IB2, and IIA1 cervical cancer (according to International Federation of Gynecology and Obstetrics [FIGO] 2018) were treated with pHDR-BT, and 6 to 8 weeks later followed by radical hysterectomy. Patients found to have positive lymph nodes, residual cervical cancer, involved parametria, or lymphovascular space invasion (LVSI) received post-operative adjuvant therapy.

Material And Methods: We retrospectively analyzed multiple PSA kinetics related to PSA nadir (nPSA), PSA bouncing, and biochemical recurrence (BCR) in 186 PCa patients treated with neoadjuvant androgen deprivation therapy (ADT), followed by EBRT combined with HDR-BT boost.

Basal Cell Carcinoma Treated with High Dose Rate (HDR) Brachytherapy-Early Evaluation of Clinical and Dermoscopic Patterns during Irradiation.

Basal cell carcinoma (BCC) is the most frequent malignancy of the Caucasian population. Dermoscopy is an established diagnostic method providing the bridge between clinical and pathological examination. Surface skin high dose rate (HDR) brachytherapy is an organ sparing treatment method used for non-surgical candidates.

Advanced dose calculation algorithm in superficial brachytherapy - the impact of tissue inhomogeneity on treatment plan dosimetry.

Purpose: Given tissue inhomogeneity and lack of backscatter media, superficial brachytherapy necessitates more accurate dosimetry than TG-43 formalism. However, the introduction of modern model-based dose calculation algorithms into clinical practice should be carefully evaluated. The aim of this work was to compare dose distributions calculated with TG-43 and advanced collapsed cone engine (ACE) algorithms for individual multi-catheter moulds, and investigate the impact of target size and the lack of bolus to differences between plans.

The Proper Administration Sequence of Radiotherapy and Anti-Vascular Agent-DMXAA Is Essential to Inhibit the Growth of Melanoma Tumors.

Vascular disrupting agents (VDAs), such as DMXAA, effectively destroy tumor blood vessels and cause the formation of large areas of necrosis in the central parts of the tumors. However, the use of VDAs is associated with hypoxia activation and residues of rim cells on the edge of the tumor that are responsible for tumor regrowth. The aim of the study was to combine DMXAA with radiotherapy (brachytherapy) and find the appropriate administration sequence to obtain the maximum synergistic therapeutic effect.

Exclusive 3D-brachytherapy as a good option for stage-I inoperable endometrial cancer: a retrospective analysis in the gynaecological cancer GEC-ESTRO Working Group.

Purpose: Analyse outcomes of stage-I inoperable endometrial cancer (EC) patients from seven European centres treated with 3D-image-guided brachytherapy (IGBT) alone.

Materials And Methods: From 2004 to 2018, 62 patients (41 stage-IA and 21 IB) were retrospectively studied, analysing anaesthetic procedure, applicator type, BT-planning imaging, clinical target volume (CTV), BT schedule, overall daily-dose equivalent to 2 Gy (EQD2) to the CTV and D2 cm for organs at risk. Complications were evaluated using CTCAEv4 scores.

Brachytherapy in a Single Dose of 10Gy as an "in situ" Vaccination.

Radiotherapy (RT) is one of the major methods of cancer treatment. RT destroys cancer cells, but also affects the tumor microenvironment (TME). The delicate balance between immunomodulation processes in TME is dependent, among other things, on a specific radiation dose.
